It should be further noted that, when the end of the driving shaft 231 connected to the driven shaft 232 rotates to a direction horizontally toward the side of the cutting mechanism 3 (the first output shaft 233 moves to the left end of the side hole 263 shown in fig. 5), the first output shaft 233 is fixedly connected to the electric suction cup 671 on the left side of fig. 20, and when the driving shaft 231 starts to drive the driven shaft 232 to move to the other side from this state, the PLC controller immediately controls to stop the electric suction cup 671 on the side, so that the transmission assembly 6 does not move synchronously with the first output shaft 233 when the driving shaft 231 starts to move, and when the first output shaft 233 moves to the position of the electric suction cup 671 on the other side, the period is 1 second, then the PLC controller immediately controls to start the electric suction cup 671 on the side, so that the first output shaft 233 and the transmission assembly 6 are connected together, and then the transmission assembly 6 can synchronously drive the flattened heat shrink sleeve to perform movement adjustment along with the movement of the first output shaft 233.

When the end of the driving handle 231 connected with the driven handle 232 rotates to the direction of one side where the winding mechanism 4 is located, that is, when the first output shaft 233 moves to the position of the contact sensor 262 on the right side in fig. 5, after that, the driving handle 231 starts to drive the driven handle 232 to move back, so that the first output shaft 233 is also driven to move back, at this time, the PLC controller immediately stops the electric suction cup 671 on the side, so that the first output shaft 233 and the conveying component 6 are not connected into a whole, and when the first output shaft 233 moves to the position of the electric suction cup 671 on the other side, the interval is 1 second, then the PLC controller immediately controls the electric suction cup 671 on the side to be started, so that the first output shaft 233 is connected with the conveying component 6 into a whole again, and then the conveying component 6 can move and adjust synchronously along with the movement of the first output shaft 233 to the side close to the fixed cylinder 24.

In the following process, the rotation direction of the rotation handle 641 is the anticlockwise direction shown in fig. 1 (namely, the anticlockwise rotation of the side winding mechanism 4 where the arrangement mechanism 2 is located), after the flattened heat-shrinkable sleeve is moved out of the fixed cylinder 24, the flattened heat-shrinkable sleeve is continuously pushed on one side of the fixed cylinder 24 so that one end of the flattened heat-shrinkable sleeve gradually moves between the C-shaped frames 61 on two sides until the end of the heat-shrinkable sleeve is level with one end of the C-shaped frames 61, the rotating motor five is started by the PLC controller so as to control the rotation of the synchronous wheel three 63 and the synchronous wheel four 64, the rotation handle 641 synchronously rotates along with the step wheel four 64, so that the connecting strip 651 moves circularly along with the rotation handle 641, the lifting piece 66 is pressed on the surface of the heat-shrinkable sleeve at the moment, and the lifting piece is pressed against the spring six by the action of the lifting piece 66, and then, the end of the transmission assembly 6 and the clamped heat-shrinkable sleeve are driven by the driving handle 231, the driven handle 232 and the first output shaft 233 to move to the side close to the winding drum 43 until the first output shaft 233 moves to the end of the side hole 263 close to the side of the winding drum 43, at this time, the right end of the C-shaped frame 61 is in contact with the outer surface of the winding drum 43, the rotating motor five is continuously started by the PLC controller, so that the connecting bar 651 continuously rotates with the rotating handle 641, the end of the heat-shrinkable sleeve is conveyed forward by the lifting member 66, during the movement of the rotating handle 641 for completing the second cycle, when the lifting member 66 is separated from the surface of the heat-shrinkable sleeve, the end of the heat-shrinkable sleeve has been moved to the position contacting the third sensor 47 against the elastic plate 437, and then, when the rotating handle 641 completes the second cycle, the rotating motor five is stopped, the securing peg is in a vertically upward position.

Then, during one round trip of the output shaft one 233, the conveying assembly 6 presses the heat-shrinkable sleeve in conveyance from a position close to the fixed cylinder 24, that is, pauses when the fixing bolt rotates to a vertically downward position, and then feeds out the heat-shrinkable sleeve at a position close to the winding drum 43, that is, stops to a vertically upward position after the fixing bolt rotates a half turn again, and then moves back to a position close to the fixed cylinder 24 with the output shaft one 233, and sequentially circulates.

Wherein the reciprocating speed of the conveying component 6 at other times is consistent with the speed of the winding drum 43 for winding the heat-shrinkable sleeve except the process of firstly conveying the end part of the heat-shrinkable sleeve into the winding drum 43.

The application method of the winding and cutting integrated machine for the PVC heat-shrinkable sleeve comprises the following steps:

Firstly, one end of a heat-shrinkable sleeve is inserted into a fixed cylinder 24 after passing through a cutting mechanism 3, the end of the heat-shrinkable sleeve is inserted forward along a guide plate 243 and passes through the lower part of a pressing plate 241, so that the heat-shrinkable sleeve passing through the fixed cylinder 24 forms a flat structure under the action of the two heat-shrinkable sleeves, after the end of the heat-shrinkable sleeve is flattened and removed from the fixed cylinder 24, the heat-shrinkable sleeve is pushed forward again, the end of the heat-shrinkable sleeve falls at one end of a C-shaped frame 61 of a two-side conveying assembly 6, the end of the heat-shrinkable sleeve is flush with one end of the C-shaped frame 61, a rotating motor five is started through a PLC (programmable logic controller) to control the rotation of a synchronous wheel three 63 and a synchronous wheel four 64, and the synchronous driving rotating handle 641 is synchronously driven to rotate together, thereby a connecting strip 651 drives a lifting piece 66 to reciprocate, and when the rotating handle 641 is rotated to a vertical downward position, the lifting piece 66 is tightly pressed on the heat-shrinkable sleeve to be fixed between the two C-shaped frames 61;

Secondly, a first rotating motor is started through a PLC controller to drive the first rotating motor to rotate the driving gear 22, so that the fluted disc 23 is indirectly driven to rotate, the driving handle 231 synchronously moves along with the rotation of the fluted disc 23, and meanwhile, the driving handle 231 drives the driven handle 232 connected with the driving handle 231 to move together;

The states of the driving lever 231 and the driven lever 232 include the following two specific states:

In the state a, when the end of the driving handle 231 connected to the driven handle 232 is located in the horizontal left direction as shown in fig. 2, that is, when the first output shaft 233 contacts with the left end of the side hole 263, the C-shaped frame 61 is located nearest to the position of the fixed cylinder 24, and when the first output shaft 233 contacts with the electric suction cup 671 at the left end of the first connecting groove 67, as the driving handle 231 moves from this position to the right direction as shown in fig. 2, the first output shaft 233 slides from the left end to the right end along the first connecting groove 67 under the action of the driven handle 232 and is connected with the electric suction cup 671 on the right side as a whole, and then the C-shaped frame 61 continues to move to the right side as shown in fig. 2 along with the first output shaft 233;

in the state B, when the end of the driving shaft 231 connected to the driven shaft 232 is located in the horizontal right direction in fig. 2, that is, when the first output shaft 233 contacts the right end of the side hole 263, the C-shaped frame 61 is located closest to the winding drum 43, and in this state, there are two cases:

In case a, when the end of the heat-shrinkable sleeve is about to be contacted with the winding drum 43 for the first time (i.e. the end of the heat-shrinkable sleeve is fixed), at this time, one end of the C-shaped frame 61 is contacted with the outer surface of the winding drum 43, the lifting member 66 is controlled to move synchronously with the rotating handle 641 by continuously starting the rotating motor five, so that the end of the heat-shrinkable sleeve pressed at the bottom moves into the winding drum 43, and in the process of completing the second rotating cycle of the rotating handle 641, when the lifting member 66 is separated from the surface of the heat-shrinkable sleeve, the heat-shrinkable sleeve is already moved to the position contacting the third sensor 47 against the elastic plate 437 and triggers the third sensor 47, at this time, the electromagnet two 46 is started and the ejector rod 438 penetrating through the inside is firmly fixed, so that the positions of the positioning plate 434 and the rotating drum 435 are fixed, and the end of the heat-shrinkable sleeve is also fixed at the notch position of the first inner groove 431;

In the case B and the subsequent reciprocation process except the case a, when the C-shaped frame 61 moves to the position, the lifting member 66 continues to rotate along with the rotating handle 641 until the rotating handle 641 is in the vertically upward position, then the C-shaped frame 61 moves back to the position of the state a along with the first output shaft 233, at this time, the rotating handle 641 continues to rotate to the vertically downward position to compress and pause the heat-shrinkable sleeve, and then moves to the position of the state B along with the first output shaft 233, so that the heat-shrinkable sleeve is conveyed in a reciprocating circulation assistance manner;

Then, after the end part of the heat-shrinkable sleeve is fixed, the driving motor is started to enable the driving piece 58 to rotate along with the end part under the action of the transmission component 531, the heat-shrinkable sleeve starts to be rolled, after the rolling tube 43 is wound for one circle (namely, the driving piece 58 rotates for one circle), the electromagnet II 46 stops working, at the moment, under the action of the spring III and the spring IV, the elastic plate 437 moves reversely to reset, so that the positioning plate 434 at the moment also resets and rotates under the action of the rotating cylinder 435 immediately, and the reset is stopped when the elastic plate 437 cannot move continuously;

Meanwhile, in the process of rolling the rolling drum 43, the adjusting piece 57 moves to the side where the first fixing plate 52 is located from an initial position (the position can be set by itself and the position is different according to the difference of rolling circle numbers) under the action of the screw drive, at the moment, one end of the guide sleeve 56 contacts with the side wall of the second fixing plate 53, when the adjusting piece 57 moves into the clamping hole of the adjusting gear 54, the limit key 59 originally embedded in the clamping hole is directly ejected, so that the adjusting gear 54 and the adjusting piece 57 are connected into a whole at the moment, the other end of the adjusting piece 57 just leaves the guide sleeve 56, at the same time, the third electromagnet 584 stops working, the fourth electromagnet starts to start, so that the screw rod 582 and the input part 581 at the moment are integrated, the output part 583 is firmly fixed between the inner walls of the first fixing plate 52 and cannot act, then, with the continuous output of the driving motor, the adjusting gear 54 rotates along with it and synchronously drives the transmission gear two 55 below to rotate, then the transmission gear one 51 on the other side is controlled to synchronously rotate along with it, with the start rotation of the transmission gear one 51, the synchronous wheel one 122 synchronously drives the rotation of the synchronous wheel two 322 under the drive of the synchronous shaft one 121 (in the state that the electromagnet is in the power-on working state), the synchronous wheel two 322 controls the rotation of the synchronous shaft two 321, so that the bevel gears two 37 on the two sides drive the bevel gears one 36 meshed with the bevel gears two to rotate, and then controls the rotation of the output shaft two 33, and with the arrangement of the lines on the output shaft two 33 opposite to each other, the upper and lower cutters 35 are respectively moved and adjusted along with the two moving strips 34 to the side close to the middle, thereby realizing the cutting operation of the heat-shrinkable sleeve (during the period, the adjusting gear 54 rotates only 1/4 circle, namely 90 degrees), the rotation angle sensor starts synchronously and monitors the rotation angle in the process when the adjusting gear 54 starts rotating, then after the cutting operation is finished, the driving motor is started again and rotated reversely by 90 degrees, so that the adjusting gear 54 and the adjusting piece 57 are reset to the position just contacted, the cutting mechanism 3 is reset, then, the electromagnet is stopped to work, then, the position of the guide sleeve 56 is moved to be contacted with the adjusting gear 54, the input part 581 and the screw rod part 582 are driven continuously, and the adjusting piece 57 is moved to be reset to the side of the second fixed plate 53 along the guide hole of the guide sleeve 56;

After the adjusting piece 57 is reset, the electromagnet III 584 is started, the electromagnet IV is stopped, so that the output part 583 is connected with the screw rod part 582 and the input part 581 again to form a whole, and the winding drum 43 is continuously controlled to wind the rest part according to the original winding direction under the action of the driving motor until all winding is finished;

after all the heat-shrinkable tubes are rolled, the movable frame 41 is controlled to move to the other side along the direction of the first fixed groove 13, so that the limiting piece 42 drives the clamped heat-shrinkable tubes to be taken down from the rolling tube 43, and finally the taken-down heat-shrinkable tubes are bundled and fixed.
