The hollow pneumatic cylinder 701 has a cylinder liner 703 and a telescopic rod 704, wherein the cylinder liner 703 is fixedly arranged in the second mounting hole of the outer side wall 602.

The test cylinder 705 is fixedly arranged at the end part of the telescopic rod 704 of the hollow pneumatic cylinder 701, and the hollow pneumatic cylinder 701 can drive the test cylinder 705 to move; an air charging hole 706 is arranged in the test cylinder 705 in a penetrating way, the air charging hole 706 is in butt joint communication with the second air charging channel 702, and the end part of the test cylinder 705, which is opposite to the telescopic rod 704, protrudes outwards along the radial direction to form a limiting clamp protrusion 707;
And the test clamping sleeve 708 is arranged on the outer surface of the outer side wall 602 of the hollow sector-shaped detection block 6 and corresponds to the second mounting hole, and the test clamping sleeve 708 is matched with the limit clamping protrusion 707 so as to compress the rubber product 9 to be detected.
As shown in fig. 1 and 4, the hollow sector detection block 6 includes a ceiling wall 603 having a sector shape, and left and right and inner side walls 601, 602 connected to the ceiling wall 603. Wherein, the left and right side walls are rectangular plate-shaped, and the inner and outer side walls 601, 602 are arc-shaped plate-shaped. The shapes of all the hollow sector detection blocks 6 are the same, and the corresponding central angle of each hollow sector detection block 6 is 360 degrees/n. Thus, the n hollow sector-shaped detection blocks 6 are closely arranged in the circumferential direction to form a circular ring shape.
Wherein, the inner side wall 601 of the hollow sector detection block 6 is a side wall close to the center of the bearing disc 4, and the outer side wall 602 is a side wall far away from the center of the bearing disc 4. Further, the number of the first mounting holes and the second mounting holes is two, and the two first mounting holes and the two second mounting holes are respectively arranged at the positions of the inner side wall 601 and the outer side wall 602 of the hollow sector detection block 6, which are close to the diagonal points. Thus, the rubber product detection devices 7 provided in the first mounting hole and the second mounting hole can be prevented from interfering with each other. In this way, the number of the rubber product detection devices 7 to be provided is increased.
In order to prevent the second inflation line 8 connected to the second inflation channel 702 from being entangled during the rotation of the rubber product detection apparatus 7, the embodiment of the present invention provides the slip ring 5 to enable the second inflation line 8 to rotate in synchronization with the rubber product detection apparatus 7. Therefore, during the operation of the rubber product detection apparatus according to the embodiment of the present invention, the second inflation line 8 and the rubber product detection device 7 remain relatively stationary, so that the second inflation line 8 is prevented from being twisted and wound with each other.
As shown in fig. 5, the first inflation channel may be a through hole concentrically provided in the cylindrical body 501 of the slip ring 5, the lower end of which is in communication with the air source through the first inflation line. Alternatively, the first inflation channel may be a part of the first inflation line, that is, a through hole is concentrically provided in the cylindrical body 501, and the upper end of the first inflation line is inserted into the through hole to form the first inflation channel.
The rotary joint 503 is in the shape of a hollow cylinder, is disposed at the upper end of the first inflation channel, and has a degree of freedom of circumferential rotation. To maintain the tightness of the inflation, the swivel 503 is in sealing connection with the first inflation channel. Specifically, the inner wall of the first inflation channel may have a sealing step in a ring shape, and a sliding sealing friction pair is disposed between the lower end of the rotary joint 503 and the sealing step. Thereby, the tightness between the rotary joint 503 and the first inflation passage is ensured without affecting the rotation of the rotary joint 503.
To enable communication of one air source with a plurality of rubber product detection devices 7, the swivel joint 503 may be implemented with the rubber product detection devices 7 by a four-way joint provided in a branched form.
As shown in fig. 7, the rotary joint 503 is connected to the vertical ports of the three-way joint 10, and the two horizontal ports of the three-way joint 10 are respectively connected to the horizontal ports of the two first-stage four-way joints 11.

Two vertical ports of the second-stage four-way joint 12 are respectively communicated with the second inflation channel 702 through a second inflation pipeline 8, the other horizontal port of the second-stage four-way joint 12 is connected with one vertical port of the third-stage four-way joint …, and so on until all the second inflation channels 702 are communicated with the rotary joint 503 through the four-way joint.
Thus, each horizontal port of the three-way joint 10 is correspondingly connected with the rubber product detection device 7, and the sweeping radian of the rubber product detection device along the circumferential direction is 180 degrees. That is, all the rubber product inspection devices 7 are divided into two, wherein one half of the rubber product inspection devices 7 communicate with one horizontal port of the three-way joint 10 through the connection network formed by the four-way joint, and the other half of the rubber product inspection devices 7 communicate with the other horizontal port of the three-way joint 10 through the connection network formed by the four-way joint.
By this, through the above structural design, the air supply to all the rubber product detecting devices 7 can be realized by using one air source. Thus, the uniformity of air supply is better, and the implementation cost is lower.

The cylindrical body 501 is provided with an endless track in sliding contact with a plurality of brushes. The loop draws two power supply lines 506, and a plurality of pneumatic cylinders 701 are connected to the two power supply lines 506.
In this embodiment, the brushes are plate-like or sheet-like and made of a conductive material such as metal. The ring is cylindrical, the outer wall of the ring is inwards recessed to form an annular groove, and a plurality of brushes extend into the annular groove. Therefore, the annular groove can limit the electric brush, so that the electric brush can be well contacted with the loop, and conductive connection is realized.
The lower end of the cylindrical body 501 is provided with a containing groove corresponding to the first inflation channel, and the loop is fixedly arranged in the containing groove in an interference fit manner. Thus, the cylindrical body 501 can drive the ring to rotate synchronously during the rotation process.
Two power supply lines 506 are led out from the upper end of the loop for supplying electric power to the plurality of hollow pneumatic cylinders 701. The carrier disc 4 may be provided with a stop collar, on which holes corresponding to the plurality of hollow pneumatic cylinders 701 are provided. An intermediate conductive wire connected to a plurality of hollow pneumatic cylinders 701 is inserted in the hole and connected to a power supply line 506.
As shown in fig. 1 to 4, the support 1 is further provided with a support frame 13, and the support frame 13 is provided with a control cabinet 14 for controlling the operation of the motor. One side of the support 1 corresponding to the support frame 13 is provided with a transparency detection mechanism (not shown) for detecting the transparency of the rubber product, a first operation station is formed on the opposite side of the support 1 to the support frame 13, a second operation station is formed on the side of the support 1 between the first operation station and the support frame 13, and the second operation station is located at the downstream of the first operation station along the rotation direction of the bearing disc 4.
In this embodiment, the transparency detecting mechanism is used to detect the transparency and the uniformity of the transparency of the rubber product 9 to be detected in the inflated state after the inflation, and may be implemented by any suitable existing configuration.
Specifically, for example, the transparency detection mechanism may adopt a photographing device (such as a camera) that is commonly used at present, and determine whether the transparency and the transparency uniformity of the rubber product 9 to be detected meet the requirements by taking a photograph of the rubber product 9 to be detected in a bulge state and transmitting the photograph to a computer in the control cabinet 14 for analysis.
Or an illumination component such as an infrared emitter and a receiver can be adopted, and whether the transparency and the transparency uniformity of the rubber product 9 to be detected meet the requirements can be judged according to whether the difference between the light intensities received by the receiver is within a set range.
The first operation station and the second operation station are used for an operator to stand, and the operator can sleeve the rubber product 9 to be detected on the test cylinder 705 of the rubber product detection device 7 at the first operation station and the second operation station. Wherein the second operating station is located between the first operating station and the support frame 13, and the second operating station is located downstream of the first operating station in the direction of rotation of the carrying disc 4. Preferably, the second operating work is 90 ° out of phase with the first operating station in the direction of rotation of the carrying disc 4, and the support frame 13 is 180 ° out of phase with the first operating station in the direction of rotation of the carrying disc 4. Namely, taking the first operation station as a starting point, the bearing disc 4 rotates 90 degrees to reach the position of the second operation station, and rotates 180 degrees to reach the position of the supporting frame 13.
Further, a collecting tank 15 is further provided on the bracket 1 for accommodating the rubber product detected by the rubber product detecting device 7 and the transparency detecting mechanism. The collecting trough 15 is located between the support frame 13 and the first operating station and the collecting trough 15 is out of phase with the first operating station by 270 ° in the direction of rotation of the carrier disc 4. I.e. starting from the first operating station, the carrier disc 4 is rotated 270 deg. to the position of the collecting trough 15.
The collection tank 15 can collect rubber products meeting both quality and transparency requirements; alternatively, the collection tank 15 may be divided into two areas, one of which is used for collecting rubber products that do not meet both the quality and transparency requirements and the other of which is used for collecting rubber products that meet both the quality and transparency requirements.
In this embodiment, the hollow pneumatic cylinder 701 may be of any suitable existing configuration, such as a hollow cylinder provided by CN206356717U, which is not limited in this embodiment of the present invention.
The end of the telescopic rod 704 of the hollow pneumatic cylinder 701 is provided with a connecting flange 709, and the connecting flange 709 and the test cylinder 705 can be fixed by a plurality of connecting bolts uniformly distributed along the circumferential direction. In order to seal the gas filled in the second gas filling channel 702 of the hollow pneumatic cylinder 701, a sealing ring is pressed between the connection flange 709 and the test cylinder 705, and the sealing ring surrounds the outlet end of the second gas filling channel 702.
An air charging hole 706 is arranged in the test cylinder 705 in a penetrating way, and the air charging hole 706 is in butt joint communication with the second air charging channel 702. Preferably, the inflation port 706 is located in the center of the test cylinder 705, i.e., the inflation port 706 is disposed concentric with the test cylinder 705. In addition, a silencing element 712 is disposed in the air charging hole 706 to silence noise generated by the air flow during air discharging, so as to avoid noise in a large decibel. The sound attenuating element 712 may take any suitable existing configuration and is not limited in this regard.
And, the end of the test cylinder 705 facing away from the telescopic rod 704 is outwards protruded along the radial direction to form a limit clamp protrusion 707, and a test clamp sleeve 708 matched with the limit clamp protrusion 707 is arranged on the outer surface of the outer side wall of the hollow sector-shaped detection block 6. Thus, the hollow pneumatic cylinder 701 can drive the test cylinder 705 to move, and when the test cylinder 705 is sleeved with the rubber product 9 to be detected, the rubber product 9 to be detected is pressed between the limiting clamp protrusion 707 and the end part of the test clamp sleeve 708.
Further, a limiting groove 710 is formed on the outer wall of the limiting clip protrusion 707 in an inward concave manner, and a flexible sealing ring 711, such as a silica gel sealing ring, is disposed in the limiting groove 710. And, further, a limit groove 710 corresponds to an end of the test ferrule 708. In this way, the flexible sealing ring 711 can increase the tightness of the sleeve between the rubber product 9 to be detected and the test cylinder 705, and can buffer the impact of the test clamping sleeve 708 on the test cylinder 705 to protect the test cylinder 705 from being damaged.
The cylinder sleeve 703 of the hollow pneumatic cylinder 701 is connected to a second inflation line 8, and the second inflation line 8 is in butt-joint communication with the second inflation channel 702. Specifically, a flange may be disposed at one end of the second inflation pipeline 8, a cylinder liner 703 of the hollow pneumatic cylinder 701 is also disposed with a flange, and the two flanges are connected by bolts. The other end of the second inflation line 8 is connected to a high-pressure air source through a rotary joint 503, a first inflation channel 502, and a first inflation line in order to inflate air into the rubber product 9 to be tested through a second inflation channel 702 of the hollow air cylinder 701 and an inflation hole 706 of the test cylinder 705.
The second inflation line 8 is provided with a pressure sensing element (not shown), which may be a pressure sensor or a pressure gauge, for example, in signal connection with the control processor, the pressure sensing element being arranged to measure the pressure of the gas flow in the second inflation line 8 when the gas is deflated. Specifically, when the deflation is started to the time t1, the pressure detection element detects that the air flow pressure is P1; when the deflation is continued to the time t2, the pressure detecting element detects that the air flow pressure is P2. When the difference between P1 and P2 is within the predetermined range [0, deltaP ], the control processor determines that the rubber article 9 to be detected is acceptable. That is, during the deflation process from time t1 to time t2, the rubber product 9 to be detected is not decompressed due to other air leakage except for normal air exhaustion through the air charging hole 706 and the second air charging channel 702. When the difference between P1 and P2 is not within the predetermined range [0, deltaP ], the control processor determines that the rubber article 9 to be detected is not acceptable. That is, during the deflation process from time t1 to time t2, the rubber product 9 to be detected is decompressed due to other air leakage besides the normal air exhaust through the air charging hole 706 and the second air charging channel 702.
In this embodiment, the control processor may be implemented in any suitable manner. In particular, for example, the control processor may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the microprocessor or processor, logic gates, switches, application SPECIFIC INTEGRATED Circuits (ASICs), programmable logic controllers (Programmable Logic Controller, PLCs), and embedded micro-control units (Microcontroller Unit, MCUs), examples of which include, but are not limited to, the following micro-control units: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, silicone Labs C8051F320. It will also be appreciated by those skilled in the art that the control unit can be implemented entirely by logic programming method steps to cause the same to be implemented in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded micro control units, etc., in addition to the functionality of the control processor being implemented in a purely computer readable program code.
In this embodiment, Δp may be determined according to practical situations, which is not limited in the embodiment of the present invention. In addition, in the present embodiment, the high pressure is calculated in kilograms. In the art, 8-10kg are considered to be high pressure. Or alternatively, higher than one normal atmospheric pressure is considered to be high pressure.
