Of course, the number of processing stations and tool positions can be flexibly adjusted according to the output and the size of the production workshop. If 8 workstations are used, 8 sets of cutters, 8 blanking channels, and a semi-tubular positioning silo 501 are selected, which are within the spirit and principle of the present invention.

There are 12 semi-tubular positioning bins 501 installed on the lower side of the outlet of the unloading channel, and the nuts can be rolled into the semi-tubular positioning bins 501 for positioning and processing through the unloading channel of the automatic nut taking and kernel automatic sorting and positioning mechanism; The positioning bin 501 can be rotated and inclined at a certain angle, and the nuts in it can be discharged into the conveyor belt below.

The semi-tubular positioning bins 501 for loading nuts are installed on the rotating bracket 502. There are 12 semi-tubular positioning bins 501, each of which is facing the outlet of one unloading channel, and the nuts coming out of the unloading channel will fall on the The semi-tubular positioning silo 501 is similar to a nut peeling and kernel processing station, and has a better positioning function by adopting the design of the semi-arc cross-section tubular positioning silo.

The two ends of the rotating bracket 502 are provided with rotating rods 503 , one end of which is inserted into the upper bearing of the multi-tool mechanism frame 3 , and the other end extends to the outside of the multi-tool mechanism frame 3 and is hinged with the connecting swing rod 504 .

The connecting pendulum rod 504 can drive the rotating rod 503 to rotate back and forth to realize the rotation, inclination and reset of the semi-tubular positioning bin 501 .

The other end of the connecting pendulum rod 504 is eccentrically connected with a rotating plate 505, and the center of the rotating plate 505 is connected with a positioning and processing silo rotating motor 506. The rotation of the positioning and processing silo rotating motor 506 drives the connecting pendulum rod 504 to move to realize a semi-tubular positioning silo. 501 rotation tilt and reset. Of course, other mechanical structures such as air cylinders and cam mechanisms can also be used to push the connecting pendulum rod 504 , so as to realize the rotation, tilt and reset of the semi-tubular positioning bin 501 .

The rotary motor 506 of the positioning and processing bin is fixed on the multi-tool frame 3 through the mounting plate, and its output shaft is fixedly connected with the rotary disk 505 .

The front and rear ports of the semi-tubular positioning silo 501 are symmetrically arranged with 12 sets of fixed knives 2 and 1 movable knives with opposite knife edges, that is, two pairs are a group, a total of 12 fixed knives 2 and 12 movable knives 1, please refer to Fig. 1 to Figure 5.

The specific installation method is as follows. The fixed knife 2 is installed on the multi-tool frame 803 through the fixed knife holder plate 201 facing the front port of the semi-tubular positioning bin 501, and there are 12 in total.

The moving knife 1 is installed on the moving knife rest plate 101, that is, the rear port of the moving knife 1 is installed on the moving knife rest plate 101 by tightening the pressing plate I102, there are 12 in total.

The moving knife holder plate 101 drives the moving knife 1 to move closer to or away from the fixed knife 2 through the sliding screw 103, that is, the sliding screw 103 is connected with the servo motor 107, and the servo motor 107 drives the sliding screw 103 to rotate, so as to drive the screw The rod slider 104 and the moving knife holder plate 101 move, so that the moving knife 1 can move to the fixed knife 2 or move away from the fixed knife 2. Of course, a linear push rod motor with adjustable stroke can also be used to achieve the same technical effect. or cylinder.

The sliding block 105 is installed on both sides of the moving tool rest plate 101, and the sliding rail 106 is installed on the multi-tool mechanism frame 3. The design of the sliding block 105 and the sliding rail 106 ensures the smooth movement of the moving tool rest plate 101 and the moving knife 1 ,precise.

By moving the moving knife 1 to the fixed knife 2, after the two knives are basically abutted, the knife edges can be closed, and the nuts located in the semi-tubular positioning bin 501 can be squeezed and broken accurately and efficiently.

Further, as shown in FIG. 6 , the movable knife 1 and/or the fixed knife 2 includes a shell-breaking knife 1102, and the shell-breaking knife 1102 is crescent-shaped. Therefore, through the abutment of the crescent-shaped knives in the static station, the double-knife for nuts can be realized. Opening, the opening is double arc, which can basically be butted, so the nut shell is very easy to fall off, and the sliding screw pair controlled by the servo motor, that is, the sliding screw and the slider to control the moving knife 1, can quickly align the moving knife 1 and The fixed knife 2 is controlled by the knife when the shell is broken. For example, when the diameter of the nut is too small, the mobile knife 1 and the fixed knife 2 may not be able to completely break the shell. Therefore, it is necessary to adjust the feed stroke of the mobile knife holder plate 101, which is programmable by PLC. The logic controller controls the servo motor 107, and then controls the feed stroke of the moving tool holder plate 101. When using, it is only necessary to manually adjust the parameters on the screen according to the size of the nut diameter, so that the machine's shell breaking rate and integrity can reach an ideal level. state, control is more convenient, and has better human-computer interaction.

The movable knife 1 and the fixed knife 2 also include a knife shank 1101, the shell-breaking knife 1102 is installed on one end of the knife shank 1101, and the other end is installed on the movable knife rest plate 101 or the fixed knife rest plate 201 by tightening the pressure plate, and the knife rod 1101 A knife sleeve 1103 is slidably sleeved on the side close to the shell breaking knife 1102. The shell breaking knife 1102 is extended outside the end face of the knife sleeve 1103, the end face is an arc surface, and the other end face is provided with a spring 1104, which is sleeved on the knife On the rod 1101, it can press the knife sleeve 1103 to give a certain pressure to the knife sleeve 1103, and the knife sleeve 1103 has certain functions of holding, clamping and positioning the nuts during the process of breaking the shell of the nuts.
