DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 As shown, in the embodiment of the utility model, a film cutting and rolling machine tension control device comprises a mounting frame 1, on which a guide roller 2 is symmetrically rotatably connected for conveying a film, a movable notch 3 is symmetrically arranged in the middle of the mounting frame 1, slide rails 4 are arranged on both sides of the movable notch 3, and sliding blocks 5 are slidably connected on the slide rails 4, and the movable notch 3 is used for the movement of the sliding blocks 5, and a tensioning roller 6 is rotatably connected between the two sliding blocks 5, and an adjusting mechanism 7 is arranged on the sliding blocks 5, and the adjusting mechanism 7 is used to drive the sliding blocks 5 to move up and down on the slide rails 4, and then adjust the upper and lower positions of the tensioning roller 6 in the movable notch 3, a dust scraping frame 8 is arranged on one side of the upper part of the mounting frame 1, and a plurality of electric push rods 9 are arranged below the dust scraping frame 8, and a mounting frame body 10 is arranged on the telescopic ends of the plurality of electric push rods 9, and a driving mechanism 11 is arranged on the mounting frame body 10, and a dust scraping assembly 12 is fixedly connected to the output end of the driving mechanism 11;

[0024] After the film to be rolled up passes through the guide roller 2 and the tensioning roller 6, the sliding block 5 is driven to move up and down along the slide rail 4 by adjusting the adjusting mechanisms 7 on both sides, and then the up and down movement position of the tensioning roller 6 in the movable groove is adjusted. By adjusting the position of the tensioning roller 6, the transported film above the tensioning roller 6 has a certain tensioning force to avoid loosening during film transportation. In addition, when the tensioning roller 6 is adjusted, the electric push rod 9 moves down to drive the dust scraping assembly 12 under the mounting frame 10 to move down until the dust scraping assembly 12 is located on the surface of the film being transported between the guide roller 2 and the tensioning roller 6. The driving mechanism 11 adjusts the specific angle of the dust scraping assembly 12 until the dust scraping assembly 12 fits the surface of the film and scrapes off some dust stuck on the surface of the film, which can avoid the film from being easily loosened during the winding process, resulting in uneven film thickness and affecting product quality, and can scrape off some dust on the surface of the film.

[0025] In one embodiment, see Figure 1 and Figure 2 As shown, limiting holes 51 are provided on both sides of the upper part of the sliding block 5, and a plurality of threaded holes 41 are provided on the slide rail 4. The sliding block 5 is provided with fastening bolts for passing through the limiting holes 51 and the threaded holes 41. When the sliding block 5 is adjusted to a suitable position by the adjusting mechanism 7, and the position of the tensioning roller 6 has reached a suitable position, the film is effectively tensioned at this time, and a fastening bolt (not shown in the figure) is passed through the limiting hole 51 and a corresponding threaded hole 41 on the slide rail 4 to fix the entire sliding block 5, thereby fixing the position of the tensioning roller 6 and preventing the tensioning roller 6 from being loosened due to force. When the position of the sliding block 5 needs to be adjusted again, the fastening bolt can be removed.

[0026] In one embodiment, see Figure 1 and Figure 2 As shown, the adjustment mechanism 7 includes an adjustment seat 71, which is fixedly connected to both sides of the mounting frame 1. A lifting screw 72 is rotatably connected to the adjustment seat 71. The end of the lifting screw 72 away from the adjustment seat 71 is fixedly connected to a connecting block 73, and the connecting block 73 is fixedly connected to the sliding block 5. When it is necessary to adjust the position of the sliding block 5 on the slide rail 4, the lifting screw 72 is rotated to drive the connecting block 73 to move down or up, thereby adjusting the sliding block 5 to move up and down on the slide rail 4, and then adjusting the up and down position of the tensioning roller 6 in the movable slot 3 to achieve the adjustment of the film tension.

[0027] In one embodiment, see Figure 1 and Figure 2 As shown, a rotating handle 74 is provided on the lifting screw 72 . The provision of the rotating handle 74 facilitates an operator to rotate the lifting screw 72 .

[0028] In one embodiment, see Figure 1 , Figure 2 and Figure 3As shown, the driving mechanism 11 includes a support frame 111, and a support frame 111 is arranged on the mounting frame 10, and the support frame 111 is arranged below the dust scraper frame 8, and a driving motor 112 is arranged on one side of the upper part of the support frame 111, and the output end of the driving motor 112 is fixedly connected with a rotating shaft 113, and the rotating shaft 113 is rotatably connected to the support frame 111, and a dust scraper assembly 12 is fixedly connected to the rotating shaft 113. When the height position of the tensioning roller 6 in the movable groove 3 changes, the conveying angle of the film will also change accordingly. At this time, the driving motor 112 can drive the rotating shaft 113 to rotate, and then adjust the dust scraper assembly 12 fixedly connected to the rotating shaft 113 to a certain angle, so that the dust scraper assembly 12 is in contact with the surface of the film transported between the guide roller 2 and the tensioning roller 6, and a small amount of dust on the surface of the film is scraped off, so as to avoid some dust on the surface of the film affecting the quality of the product.

[0029] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the dust scraping assembly 12 includes a connecting frame 121, which is fixedly connected to the rotating shaft 113. A dust scraping plate 122 is arranged below the connecting frame 121. The connecting frame 121 is fixedly connected to the rotating shaft 113 so that the dust scraping plate 122 can adjust its angle as the rotating shaft 113 rotates to adapt to different production processes and film transportation angles.

[0030] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the scraper plate 122 is detachably connected to the bottom of the connecting frame 121. The scraper plate 122 is detachably connected to the bottom of the connecting frame 121. The scraper plate 122 is easier to clean and replace. During use, the scraper plate 122 is accumulated or contaminated by dust. The operator can easily remove the scraper plate 122 for cleaning or replacement.

[0031] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, a rubber layer 123 is provided on the scraper plate 122. The softness of the rubber layer 123 can reduce the friction and scratches on the surface of the film, and avoid surface damage caused by the hard material of the scraper plate 122 directly contacting the surface of the film, thereby protecting the integrity and flatness of the surface of the film. The setting of the rubber layer 123 effectively improves the cleaning effect of the scraper plate 122 and can protect the surface of the film, making the entire scraper assembly 12 more suitable for use in the film production process.
