[0020] The linkage mechanism comprises a connecting seat 4, a pair of guide rods 5 movably arranged inside the connecting seat 4, the guide rods 5 being fixedly installed inside the mounting table 1, the guide rods 5 being capable of keeping the stability of the connecting seat 4 during movement, the connecting seat 4 being provided with a mounting groove 6 on one side, the mounting groove 6 being provided with a limiting ring 7 fixedly installed on the inner wall surface of the mounting groove 6 on both sides, the connecting pipe 8 being rotatably arranged inside the limiting ring 7, the connecting pipe 8 being capable of rotating under the limitation of the limiting ring 7, and the connecting seat 4 being capable of moving along the guide rods 5, the connecting seat 4 being capable of moving the limiting ring 7 and the connecting pipe 8 at the same time; the reciprocating screw rod 2, the guide rod 5, the connecting pipe 8 and the winding roller 15 are arranged in parallel along the length direction; the connecting pipe 8 is movably sleeved outside the guide rod 5 on one side, the connecting pipe 8 being capable of moving along the length direction of the guide rod 5 with the movement of the connecting seat 4, and the connecting pipe 8 being capable of rotating around the guide rod 5;

When the pull rod 10 is pulled, the pull rod 10 will be inclined, and the pull rod 10 can drive the connecting pipe 8 to rotate when the pull rod 10 is inclined. In this process, the reciprocating screw rod 2 can also be driven to rotate, so as to drive the connecting seat 4 and the pull rod 10 to move, and the two working states do not affect each other.
[0022] When the motor drives the reciprocating screw rod 2 to rotate, the reciprocating screw rod 2 drives the linkage block 2 and the connecting seat 4 to move, the connecting seat 4 can move along the length direction of the guide rod 5, the connecting seat 4 can drive the limiting ring 7 and the connecting pipe 8 to move, so as to drive the pull rod 10 to move along the length direction of the guide rod 5, the waste can be introduced to the specified position of the winding roller 15 by the limiting ring 13 for winding, and the waste can be uniformly wound along the length direction of the winding roller 15;
[0023] According to the description Figure 2As shown, during the winding process, the pull rod 10 needs to be slightly inclined towards one side of the winding roller 15, so that the spring 12 remains in a state of tension, and since the waste is intermittently fed to the device in small sections, the length of the waste entering the inside of the device increases after a small section is fed. The force acting on the pull rod 10 by the waste decreases, and the pull rod 10 is pulled towards the side away from the winding roller 15 under the action of the elastic force of the spring 12. Then the motor is started to drive the winding roller 15 to rotate counterclockwise by a specified angle. During the rotation of the winding roller 15, the pulling force of the waste on the pull rod 10 increases, causing the pull rod 10 to incline again towards the side close to the winding roller 15, and the spring 12 is further stretched. Then the winding roller 15 stops rotating, and a small section of waste is again fed into the device, and the cycle is repeated. In addition, it should be noted that the motor driving the winding roller 15 is a stepper motor with self-locking function, which will not rotate when stopped due to pulling, causing the tightened waste to loosen.
[0024] Working principle: During the working process of the stretch film packaging machine waste winding device, the film waste is wound on the winding roller 15 through the limiting ring 13. During the winding process, after a small section of waste is fed, the pull rod 10 will incline under the action of the elastic force of the spring 12, and the waste will always remain in a state of tension. Then the winding roller 15 is started to rotate by a corresponding angle, and the waste is wound on the winding roller 15. At the same time, the pull rod 10 will incline in the opposite direction, and the spring 12 will be further stretched. Then a small section of waste is fed again, and the cycle is repeated intermittently. At the same time of winding, the reciprocating screw rod 2 can be driven to rotate, which can drive the linkage block 3 and the connecting seat 4 to move. The connecting seat 4 moves along the length direction of the guide rod 5, which drives the connecting pipe 8 to move. The connecting pipe 8 drives the pull rod 10 and the limiting ring 13 to move, so that the limiting ring 13 can drive the waste to move on the winding roller 15, and the waste can be evenly wound on the winding roller 15.
[0025] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent substitutions or changes to the technical solution and the inventive concept of the present application within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
