[0023] Please see Figure 1 , Figure 2 as well as Figure 3This utility model provides a technical solution: a traction device for stretch film production, including a platform 1, an anti-deviation component on the top of the platform 1, and an installation component on the top of the platform 1. The anti-deviation component includes a cavity 21 inside the platform 1, a through-hole 22 on the top of the cavity 21, a drive plate 23 in the through-hole 22, a bidirectional screw 24 connected to the drive plate 23, a first motor 25 fixedly connected to one end of the bidirectional screw 24, a movable plate 26 fixedly connected to the top of the drive plate 23, limiting rings 27 on both sides of the movable plate 26, and a driving component for moving the limiting rings 27. The bidirectional screw 24 is screwed to the drive plate 23 and rotatably connected to the platform 1. The first motor 25 drives the bidirectional screw 24 to rotate. The rotation of the bidirectional screw 24 drives the two drive plates 23 to move in opposite directions, which in turn drives the movable plate 26 to move, which in turn drives the limiting rings 27 to move back and forth. The system can limit the movement of the stretch film to prevent deviation during winding and ensure winding stability. The drive component includes a fixed plate 51 fixedly connected to the top two sides of the moving plate 26, a cylinder 52 fixedly connected to one side of the fixed plate 51, and a connecting plate 53 fixedly connected to the output end of the cylinder 52. The connecting plate 53 is fixedly connected to the limiting ring 27. The fixed plate 51 can fix the cylinder 52. When the cylinder 52 works, it can push the connecting plate 53 to move, which in turn can drive the limiting ring 27 to move. The two limiting rings 27 on the front and rear sides can move left and right, moving away from the winding drum 35, which facilitates the disassembly and assembly of the winding drum 35. Support grooves 81 are respectively opened on both sides of the bottom of the cavity 21. Support blocks 82 are slidably connected in the support grooves 81. The support blocks 82 are fixedly connected to the drive plate 23. The movement of the drive plate 23 can drive the support blocks 82 to move. The support blocks 82 can guide the drive plate 23 to prevent the drive plate 23 from tilting.

[0024] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4The mounting components include vertical plates 31 fixedly connected to the top two sides of the platform 1, a rotating shaft 32 connected to the vertical plates 31, a mounting opening 33 on the top of the rotating shaft 32, a connecting rod 34 in the mounting opening 33, a winding drum 35 fixedly connected to the outside of the connecting rod 34, slots 36 on both sides of the connecting rod 34, a mounting cavity 37 in the rotating shaft 32, a sliding plate 38 in the mounting cavity 37, a push plate 39 fixedly connected to the top of the sliding plate 38, and a groove on one side of the mounting cavity 37. 40. A guide rod 41 fixedly connected to one side of the slide plate 38, a spring 42 fixedly connected to one end of the guide rod 41, and an insert rod 43 fixedly connected to the other side of the slide plate 38. The insert rod 43 is inserted into the slot 36, and the guide rod 41 is slidably connected to the groove 40. By pushing the push plate 39, the slide plate 38 can be moved. The movement of the slide plate 38 can cause the guide rod 41 to compress the spring 42, causing it to deform. At the same time, the slide plate 38 can move the insert rod 43, and the connecting rod 34 can be inserted into the mounting port 33. The spring 42 returns to its original position, which can then... The movable rod 43 is inserted into the slot 36 to fix the take-up drum 35, allowing for quick release and installation of the take-up drum 35, thus improving efficiency. One end of one of the rotating shafts 32 is fixedly connected to a second motor 91, which is fixedly connected to the vertical plate 31. When the second motor 91 is started, it drives the rotating shaft 32 to rotate, which in turn drives the take-up drum 35 to rotate, facilitating the winding of the stretch film. An anti-rotation groove 61 is provided at the bottom of the mounting port 33, and anti-rotation devices are fixedly connected to both sides of the connecting rod 34. Plate 62, anti-rotation plate 62 is inserted into anti-rotation groove 61. Anti-rotation plate 62 can be inserted into anti-rotation groove 61 to ensure that when the rotating shaft 32 rotates, it drives the connecting rod 34 to rotate, which in turn facilitates the rotation of the take-up drum 35. A positioning groove 71 is opened at the bottom of the mounting port 33. Positioning blocks 72 are fixedly connected to both sides of the connecting rod 34. Positioning blocks 72 are inserted into positioning groove 71. Positioning blocks 72 can be vertically inserted into positioning groove 71 to restrict the front and rear directions of the take-up drum 35 and prevent it from shifting back and forth.

[0025] Working principle: During operation, pushing the push plate 39 moves the slide plate 38, which in turn moves the insertion rod 43 and guide rod 41. The guide rod 41 deforms the spring 42, causing it to deform. Then, the connecting rod 34 is inserted into the mounting port 33, the positioning block 72 is inserted into the positioning groove 71, and the anti-rotation plate 62 is inserted into the anti-rotation groove 61. Releasing the push plate 39 resets the spring 42, causing the slide plate 38 to reset, which in turn resets the insertion rod 43, allowing it to insert into the slot 36. This fixes the take-up drum 35 to the rotating shaft 32, and then the wrapping film is fixed to the outside of the take-up drum 35. Starting the second motor 91 then rotates the rotating shaft 32. This can then drive the take-up drum 35 to rotate, thereby winding the stretch film. The cylinder 52, when started, can push the connecting plate 53 to move. The movement of the connecting plate 53 can drive the limiting ring 27 to move, so that the limiting ring 27 is in contact with the take-up drum 35. Then, the first motor 25, when started, can drive the bidirectional screw 24 to rotate. The rotation of the bidirectional screw 24 can drive the two drive plates 23 to move, which in turn can drive the moving plate 26 to move, which in turn can drive the limiting ring 27 to move, thereby limiting the stretch film in front and behind to prevent it from deviating during winding. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
