However, the PE film is relatively thin, and when it is laid on the first guide roller and the second guide roller, it is easy to be attracted to the equipment under the action of static electricity. Moreover, the PE film needs to be smoothed frequently during the laying process, which is inconvenient and the laying experience is not ideal.

[0005] Therefore, in order to solve the above problems, a PE film traction device is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a PE film traction device to solve the problem mentioned in the background art that the prior art device can adjust the tension of the PE film by setting a first guide roller and a second guide roller. However, the PE film is relatively thin and is easily adsorbed on the equipment under the action of static electricity when it is laid on the first guide roller and the second guide roller. Moreover, during the laying process, the PE film needs to be smoothed frequently, which is inconvenient to operate and results in an unsatisfactory laying experience.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a PE film traction device, comprising: a base plate, wherein a winding shaft is installed at the left end of the top surface of the base plate, and a conveying roller is installed at the right end of the top surface of the base plate;

[0008] A tensioning structure is installed on the top surface of the base plate. The tensioning structure includes a fixing frame, which is fixedly installed in the middle of the top surface of the base plate. A fixing guide shaft is movably installed on the surface of the fixing frame via a bearing. A guide groove is formed at the upper end of the surface of the fixing frame, and a sliding groove is formed at the lower end of the surface of the fixing frame. An installation frame is slidably installed on the inner side of the guide groove. An adjusting guide shaft is movably installed on the bottom end of the installation frame via a bearing. A hand-operated screw is rotatably connected to the top surface of the installation frame. A moving rod is slidably installed on the inner side of the sliding groove. A handle is fixedly connected to the rear end of the moving rod. A fixing plate is fixedly connected to the top surface of the moving rod. A pressure plate is slidably installed on the inner side of the fixing plate. A pull block is fixedly connected to the bottom surface of the pressure plate, and a first spring is sleeved on the outer side of the pull block.

[0009] Preferably, a limiting structure is installed at both ends of the inner side of the slide. The limiting structure includes a retaining ball, which is inserted into the top surface of the slide. A second spring is fixedly connected to the top surface of the retaining ball.

[0010] Preferably, there are two sets of fixed guide shafts, and the adjusting guide shaft is located on the lower side between the two sets of fixed guide shafts.

[0011] Preferably, the groove is adapted to the fixed guide shaft and the adjusting guide shaft.

[0013] Preferably, the pressure plate is adapted to the moving rod, the pull block passes through the fixed plate, and the two ends of the first spring are fixedly connected to the pull block and the fixed plate.

[0014] Preferably, the bottom end of the ball protrudes from the inner wall of the groove, and one end of the second spring is fixedly connected to the fixing frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By opening a groove on the surface of the fixed frame, the movable rod and the pressure plate can fix the PE film. Pulling the handle can drive the movable rod to move along the groove, which can pull the PE film to lay on the outside of the fixed guide shaft and the adjusting guide shaft so as to wind the PE film, improve the laying efficiency of the PE film, and ensure the user experience of the device.

[0016] This invention features a tension / relaxation structure. The PE film is inserted into the conveyor roller. Pulling the handle moves the moving rod, which pushes a retaining ball, causing it to retract into the inner wall of the chute. The retaining ball then compresses the second spring, releasing the limiting effect on the moving rod and allowing it to move freely within the chute to the right end. Pulling the pull block raises the pressure plate inside the fixed plate, separating it from the moving rod. One end of the PE film is placed between the moving rod and the pressure plate. Releasing the pull block causes the pressure plate to return to its original position under the elastic force of the first spring, pressing the PE film onto the top of the moving rod. When the pull block is pulled again to move the moving rod, the moving rod pulls the PE film, allowing the PE film to be laid on the outside of the fixed guide shaft and the adjusting guide shaft according to the direction of the chute. This improves the laying efficiency of the PE film and eliminates the need for frequent smoothing of the PE film, saving manpower. Then, the PE film is removed from the moving rod and wound onto the winding shaft. The winding shaft can be rotated to wind up the PE film. Rotating the hand screw can move the mounting bracket in the guide groove, and the position and height of the adjusting guide shaft can be adjusted up and down to adjust the position between the adjusting guide shaft and the fixed guide shaft, thus achieving convenient adjustment of the PE film tension.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 An embodiment of a PE film traction device provided by this utility model:

[0024] The base plate 1, winding shaft 11 and conveying roller 12 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0025] A PE film traction device includes: a base plate 1, a winding shaft 11 installed on the left end of the top surface of the base plate 1, and a conveying roller 12 installed on the right end of the top surface of the base plate 1.

[0026] A tensioning structure 2 is installed on the top surface of the base plate 1. The tensioning structure 2 includes a fixing frame 21, which is fixedly installed in the middle of the top surface of the base plate 1. A fixing guide shaft 22 is movably installed on the surface of the fixing frame 21 via bearings. A guide groove 23 is formed at the upper end of the surface of the fixing frame 21, and a sliding groove 24 is formed at the lower end of the surface of the fixing frame 21. A mounting frame 25 is slidably installed on the inner side of the guide groove 23. An adjusting guide shaft 26 is movably installed on the bottom end of the mounting frame 25 via bearings. A hand-operated screw 27 is rotatably connected to the top surface of the mounting frame 25. A moving rod 28 is slidably installed on the inner side of the sliding groove 24. A handle is fixedly connected to the rear end of the moving rod 28. 29. A fixed plate 210 is fixedly connected to the top surface of the moving rod 28. A pressure plate 211 is slidably installed on the inner side of the fixed plate 210. A pull block 212 is fixedly connected to the bottom surface of the pressure plate 211. A first spring 213 is sleeved on the outer side of the pull block 212. By opening a groove 24 on the surface of the fixed frame 21, the moving rod 28 can fix the PE film in cooperation with the pressure plate 211. Pulling the handle 29 can drive the moving rod 28 to move along the groove 24, which can pull the PE film to lay on the outside of the fixed guide shaft 22 and the adjusting guide shaft 26 so as to wind the PE film, improve the laying efficiency of the PE film, and ensure the user experience of the device.

[0027] Furthermore, a limiting structure 3 is installed at both ends of the inner side of the slide 24. The limiting structure 3 includes a retaining ball 31, which is inserted into the top surface of the slide 24. A second spring 32 is fixedly connected to the top surface of the retaining ball 31. When the moving rod 28 moves, it pushes the retaining ball 31, causing the retaining ball 31 to retract into the inner wall of the slide 24. The retaining ball 31 will squeeze the second spring 32, which can release the limiting of the moving rod 28.

[0028] Furthermore, two sets of fixed guide shafts 22 are provided, and the adjusting guide shaft 26 is located on the lower side between the two sets of fixed guide shafts 22. The fixed guide shafts 22, together with the adjusting guide shaft 26, can pull the PE film so as to wind up the PE film.

[0029] Furthermore, the slide 24 is adapted to the fixed guide shaft 22 and the adjusting guide shaft 26. When the moving rod 28 moves in the slide 24, it can pull the PE film so that the PE film is laid on the fixed guide shaft 22 and the adjusting guide shaft 26.

[0030] Furthermore, the hand-operated screw 27 passes through the fixed frame 21 and is threadedly connected to the hand-operated screw 27. Rotating the hand-operated screw 27 can drive the adjusting guide shaft 26 to move, thereby adjusting the positional relationship between the adjusting guide shaft 26 and the fixed guide shaft 22, which facilitates the adjustment of the tension of the PE film.

[0031] Furthermore, the pressure plate 211 is adapted to the moving rod 28, the pull block 212 passes through the fixed plate 210, and the two ends of the first spring 213 are fixedly connected to the pull block 212 and the fixed plate 210. The first spring 213 provides power for the pressure plate 211 to clamp the PE film in conjunction with the moving rod 28.

[0032] Furthermore, the bottom end of the locking ball 31 protrudes from the inner wall of the slide groove 24, and one end of the second spring 32 is fixedly connected to the fixing frame 21. The locking ball 31, in conjunction with the second spring 32, can limit the position of the moving rod 28 inside the slide groove 24, preventing the moving rod 28 from displacing inside the slide groove 24.

[0033] Working principle: Before use, insert the PE film into the conveyor roller 12, pull the handle 29 to move the moving rod 28. When the moving rod 28 moves, it will push the retaining ball 31, causing the retaining ball 31 to retract into the inner wall of the slide 24. The retaining ball 31 will squeeze the second spring 32, which can release the limit on the moving rod 28, so that the moving rod 28 can move in the slide 24 to move the moving rod 28 to the right end of the inner side of the slide 24.

[0034] Pulling the pull block 212 causes the pressure plate 211 to rise inside the fixed plate 210, separating the pressure plate 211 from the moving rod 28. One end of the PE film is placed between the moving rod 28 and the pressure plate 211. Releasing the pull block 212 causes the pressure plate 211 to return to its original position under the elastic action of the first spring 213. The pressure plate 211 then presses the PE film onto the top surface of the moving rod 28. Pulling the pull block 212 again causes the moving rod 28 to move, which in turn pulls the PE film, allowing it to be laid on the outside of the fixed guide shaft 22 and the adjusting guide shaft 26 according to the direction of the slide groove 24. This improves the laying efficiency of the PE film and eliminates the need for frequent smoothing of the PE film, saving manpower. Then, the PE film is removed from the moving rod 28 and wound onto the winding shaft 11. The winding shaft 11 can rewind the PE film when it rotates.

[0035] Rotating the hand screw 27 can move the mounting bracket 25 within the guide groove 23, allowing the height of the adjusting guide shaft 26 to be adjusted up and down, thereby adjusting the position between the adjusting guide shaft 26 and the fixed guide shaft 22, and realizing convenient adjustment of the PE film tension.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model.
