[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1As shown, a PE film traction device includes a base 1, a feeding assembly 2 is fixedly installed on the upper right part of the base 1, a cleaning assembly 3 is fixedly installed on the front and rear parts of the feeding assembly 2, a leveling and limiting assembly 4 is fixedly installed on the upper middle part of the base 1, and a material receiving structure 5 is fixedly installed on the upper left part of the base 1.

[0026] The PE film to be processed can be loaded through the loading component 2, so that the PE film can reach the position to be processed later at a certain speed. The dust on the upper and lower surfaces of the PE film can be processed during its movement through the cleaning component 3, thereby ensuring the production quality of the product and preventing dust particles from damaging the surface of the PE film. The smoothing and limiting component 4 can not only flatten the wrinkles on the surface of the film, but also limit the moving direction of the PE film to ensure the winding of the PE film. The PE film can be wound up through the winding structure, and the PE film roll can be freely removed after winding to a certain extent.

[0027] like Figure 2 and Figure 3 As shown, the feeding assembly 2 includes two adjusting screws 22 and two fixed plates 21. The lower ends of the two fixed plates 21 are fixedly installed at the front and rear positions of the upper right part of the base 1. Adjustment grooves 23 are opened on the opposite sides of the two fixed plates 21. The upper and lower ends of the two adjusting screws 22 are rotatably connected to the inner walls of the two adjusting grooves 23. The outer walls of the two adjusting screws 22 are threadedly connected with moving blocks 24. The opposite sides of the two moving blocks 24 are rotatably connected with adjusting rollers 25.

[0028] By rotating the two adjusting screws 22, the two moving blocks 24 can drive the adjusting rollers 25 to adjust according to the thickness of the PE film fed.

[0029] like Figure 3 As shown, a loading roller 26 is rotatably connected to the bottom of the opposite sides of the two fixed plates 21, and a motor 27 is fixedly installed at the front bottom of the front fixed plate 21. The output end of the motor 27 is fixedly connected to the front end of the loading roller 26, and the loading roller 26 is located directly below the adjusting roller 25.

[0030] The feeding roller 26 is driven to rotate below the adjusting roller 25 by the output end of the motor 27, and a PE film passes between the two rollers.

[0031] like Figure 2 and Figure 4 As shown, the cleaning assembly 3 includes four sliding rods 31, and limiting grooves 32 are provided at the upper and lower positions of the left parts of the opposite sides of the two fixed plates 21. The left and right ends of the four sliding rods 31 are fixedly installed on the inner walls of the four limiting grooves 32, and the outer walls of the four sliding rods 31 are slidably connected to sliders 33, and the opposite sides of four adjacent sliders 33 are rotatably connected to rotating rods 34, and the opposite sides of four adjacent rotating rods 34 are rotatably connected to cleaning rollers 35.

[0032] When the PE film passes through, its upper and lower surfaces drive the two cleaning rollers 35 to rotate around the four sliders 33 through the four rotating rods 34, so that the four sliders 33 slide on the four sliding rods 31, so that it can handle PE films of different thicknesses through the two cleaning rollers 35.

[0033] like Figure 4 As shown, the left and right parts of the outer walls of the four slide bars 31 are movably sleeved with springs 36, the ends of the eight adjacent springs 36 that are away from each other are fixedly connected to the front and rear parts of the outer walls of the slide bars 31, and the ends of the eight adjacent springs 36 that are close to each other are fixedly connected to the adjacent surfaces of the four sliders 33.

[0034] The eight springs 36 are subjected to pressure or tension when the slider 33 moves. The eight springs 36 convert different forces into elastic potential energy. When the slider 33 moves, the rotating rod 34 drives the cleaning roller 35 to rotate a certain angle. The elastic potential energy of the spring 36 can not only clean the surface of the PE film through the cleaning roller 35, but also reset the two cleaning rollers 35 after the film passes, which is convenient for subsequent processing of different types of films.

[0035] like Figure 5 As shown, the smoothing limit assembly 4 includes a mounting frame 41, the front and rear parts of the lower end of the mounting frame 41 are fixedly installed at the front and rear positions of the middle part of the upper end of the base 1, and the bottom position on the opposite side of the inner wall of the mounting frame 41 is rotatably connected with a reverse double-threaded rod 43, the front end of the reverse double-threaded rod 43 passes through the front part of the mounting frame 41 and is fixedly connected with a turning handle 44, and the front and rear parts of the outer wall of the reverse double-threaded rod 43 are both threadedly connected with a driving block 45.

[0036] The reverse double-threaded rod 43 is rotated by the rotation of the turning handle 44 , and the two driving blocks 45 are threadedly connected with the reverse double-threaded rod 43 to move closer to or farther from each other.

[0037] like Figure 5 As shown, a fixed roller 42 is fixedly installed at the middle position on the opposite side of the inner wall of the mounting frame 41, and sliding grooves are provided at the front and rear positions of the top of the outer wall of the fixed roller 42. The front and rear parts of the outer wall of the fixed roller 42 are movably sleeved with limiting rings 47, and the top of the inner wall of the two limiting rings 47 are slidingly connected to the inner walls of the two sliding grooves. The left and right parts of the upper ends of the two driving blocks 45 are rotatably connected with adjusting rods 46, and the ends of four adjacent adjusting rods 46 away from the driving blocks 45 are rotatably connected to the bottom of the outer walls of the two limiting rings 47.

[0038] Through the movement of the two driving blocks 45, the four adjacent adjusting rods 46 push or pull the two limiting rings 47 to move in the slide groove, so that the two limiting rings 47 can limit the PE film located therebetween.

[0039] like Figure 5As shown, an electric push rod 48 is fixedly installed in the middle of the upper end of the mounting frame 41, and the output end of the electric push rod 48 passes through the top of the mounting frame 41 and is fixedly installed with a top plate 49, and three linearly arranged spring guide shafts 410 are fixedly installed at the lower end of the top plate 49, and a smoothing plate 411 is fixedly installed at the lower end of the three spring guide shafts 410.

[0040] The output end of the electric push rod 48 drives the top plate 49 and the smoothing plate 411 to move to the surface of the PE film, so that the uneven parts of the PE film are smoothed by the smoothing plate 411 during the movement. The elastic potential energy of the three spring guide shafts 410 can turn the contact between the smoothing plate 411 and the surface of the PE film into elastic contact, thereby preventing damage to the surface of the PE film.

[0041] The working principle of the utility model is as follows: before the PE film is loaded, it passes between the adjusting roller 25 and the feeding roller 26, and according to the actual thickness of the PE film, the two adjusting screws 22 are rotated, so that the two moving blocks 24 drive the adjusting roller 25 to move downward until the surface of the adjusting roller 25 contacts the upper surface of the PE film, and the motor 27 is started. The output end of the motor 27 drives the feeding roller 26 to rotate, and the feeding roller 26 gives a leftward force to the lower surface of the PE film to move it. During the movement of the PE film, it passes through the two cleaning rollers 35. The staff rotates the handle 44 according to the length of the PE film, and the reverse double-threaded rod 43 rotates, so that the two driving blocks 45 drive the four adjusting rods 46 to push or pull the two limit rings 47, so that the opposite sides of the two limit rings 47 are attached to the two sides of the PE film to prevent the PE film from shifting in position during the movement. At the same time, the output end of the electric push rod 48 drives the smoothing plate 411 to flatten the unevenness and wrinkles on the surface of the PE film, and the three spring guide shafts 410 can prevent the surface of the PE film from being damaged due to excessive pressure.

[0042] Due to the movement of the PE film, the two cleaning rollers 35 are rotated through the four rotating rods 34 to make them fit more closely to the upper and lower surfaces of the PE film. When the four rotating rods 34 rotate, the four sliding blocks 33 are pushed to move on the sliding rods, so that the four springs 36 are subjected to extrusion force and stretching force. The different forces are converted into elastic potential energy of the springs 36. After the PE film finishes the traction work, the elastic potential energy can reset the two cleaning rollers 35.

[0043] The PE film is then rolled up by the material collection structure 5 , and after the drawing is completed, the roll formed by the PE film can be freely removed from the material collection structure 5 .

[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
