This blown film coating traction device, by comprising a top adjusting frame, a top adjusting roller, an electric cylinder support platform, an electric cylinder body, a sliding rod, and a sliding sleeve, allows for smoother vertical movement of the top adjusting frame during use. The electric cylinder body extends upwards, pushing the top adjusting frame upwards. The top adjusting roller on the top adjusting frame supports the film and lifts it upwards, increasing the film surface tension. The sliding rod and sliding sleeve facilitate smoother vertical movement of the top adjusting frame, enabling easy adjustment of film tension and addressing the problem of devices lacking this feature.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Please see Figures 1-3 This utility model provides a technical solution: a blown film coating traction device, including a worktable 1, and a smoothing component 2 for smoothing blown films of different thicknesses, an adjustment component 3 for adjusting the tension of the blown film, and a guide component 4 for guiding and limiting the blown film from left to right on the top of the worktable 1. A support plate 6 is symmetrically installed on one end of the top of the workbench 1. A second motor 7 is fixedly connected to one side of the support plate 6. A rotating rod 8 is fixedly connected to the drive end of the second motor 7. A take-up roller 10 is fixedly connected to the outer wall of the rotating rod 8. A second limiting plate 9 is fixedly connected to both ends of the take-up roller 10 on the outer wall of the rotating rod 8. A coating device 5 is fixedly connected to the top of the workbench 1 on the side near the guide component 4, and support legs are fixedly connected to the bottom of the workbench 1 around all four sides. When the film needs to be wound up, the second motor 7 is started, which drives the rotating rod 8 to rotate, which in turn drives the winding roller 10 to rotate, thus winding up the film and providing the main power for the device. The coating equipment 5 applies a protective layer to the film. The rotating rod 8 drives the two second limit plates 9 to rotate, which limits the film and prevents it from slipping off the outer wall of the winding roller 10 and getting tangled on the rotating rod 8, causing inconvenience to the workers.

[0020] Please see Figure 3 The smoothing component 2 includes connecting plates 201 symmetrically installed on the top of the workbench 1. The bottom of the connecting plates 201 is fixedly connected to the top of the workbench 1. A fixing block 204 is fixedly connected to one side of each of the two connecting plates 201. Holes are opened inside the two fixing blocks 204. A spring 206 is fixedly connected to the top of the hole. A lifting block 207 is fixedly connected to one end of the spring 206. A lifting rod 205 is fixedly connected to one side of the lifting block 207. A sliding groove is opened on one side of the fixing block 204. The width of the chute matches the diameter of the lifting rod 205. The outer wall of the lifting rod 205 is rotatably connected to the first rotating roller 208. The two ends of the first rotating roller 208 are fixedly connected to the outer wall of the lifting rod 205 with the first limiting plate 209. A fixing plate 202 is fixedly connected to one side of the two connecting plates 201 near the bottom of the fixing block 204. A fixing shaft 203 is fixedly connected between the two fixing plates 202. A second rotating roller 210 is rotatably connected to the outer wall of the fixing shaft 203. When the film needs to be smoothed, the take-up roller 10 moves the film between the first roller 208 and the second roller 210. The first roller 208 moves according to the film thickness, which in turn moves the lifting rod 205. The lifting rod 205 then moves the first limiting plate 209, which in turn moves the two lifting blocks 207. The lifting rod 205 is limited by a groove. At this time, the two lifting blocks 207 cause the spring 206 to retract. The spring 206's elasticity causes the lifting blocks 207 to move, which in turn moves the lifting rod 205. The lifting rod 205 then moves the first roller 208 and the first limiting plate 209, thus enabling the first roller 208 to press and smooth films of different thicknesses.

[0021] Please see Figure 1 and Figure 2 The adjustment component 3 includes a positioning plate 304 symmetrically installed on the top of the workbench 1. The bottom of the positioning plate 304 is fixedly connected to the top of the workbench 1. A guide groove is provided inside the positioning plate 304. A first moving block 303 is slidably connected inside the guide groove. A first motor 301 is fixedly connected to the bottom of the workbench 1. A reciprocating screw 302 is fixedly connected to the drive end of the first motor 301.

The outer wall of the guide rod 305 is slidably connected to the inner wall of the second moving block 306. A rotating rod 8 and two second limiting plates 9 are also installed between the first moving block 303 and the second moving block 306. A rotating roller is rotatably installed on the outer wall of the rotating rod 8 between the two second limiting plates 9. When wrinkles are observed in the film during operation, the first motor 301 is started, which drives the reciprocating screw 302 to rotate. The reciprocating screw 302 drives the first moving block 303 to move, which drives the rotating rod 8 to move. The rotating rod 8 drives the rotating roller and the two second limiting plates 9 to move. At the same time, the rotating rod 8 drives the second moving block 306 to move. The guide rod 305 limits and guides the second moving block 306. The rotating roller provides pressure to the film, thereby adjusting the tension of the film.

[0022] Please see Figure 2 The guide assembly 4 includes symmetrically opened limiting grooves 403 on the top of the workbench 1. The inner walls of the two limiting grooves 403 are slidably connected to guide blocks 404. The top of the guide blocks 404 is fixedly connected to a moving plate 402. A directional groove 405 is opened on one side of the moving plate 402. A bidirectional electric push rod 401 is fixedly connected near the top of the workbench 1 between the two moving plates 402.
