Description

Technical Field

[0001] This utility model relates to the field of thin film production technology, and in particular to a trimming machine for thin film production. Background Technology

[0002] BOPP film is a polymer film widely used in packaging, printing, and labeling. It features high strength, good transparency, excellent barrier properties and stiffness, as well as good moisture resistance and chemical corrosion resistance. Trimming is necessary during the production of BOPP film.

[0003] A BOPP film trimming machine is disclosed in publication number "CN222204278U". It includes a housing and a first support block. The first support block is fixedly connected to the surface of the housing. An trimming adjustment device is located inside the housing. A tension adjustment device is located on the surface of the housing. The surface of the first support block is movably connected to a guide roller via a rotating shaft. A second support block is fixedly connected to the surface of the housing. BOPP film is wound onto the surface of the guide roller. This BOPP film trimming machine, through the cooperation of the trimming adjustment device and the tension adjustment device, eliminates the need for manual adjustment of the bushing position by the operator, reducing the operator's workload and improving work efficiency. The rotating rod drives the third support block and the take-up roller to move horizontally away from the second support block, increasing the distance between the second and third support blocks and increasing the tension of the BOPP film, making the trimming of the BOPP film more precise and improving the trimming quality.

[0004] Although this solution allows the position of the cutter to be adjusted according to the width of the film, during use, after the cutter trims the film, the high winding speed causes some trimmed film fragments to stick to the surface of the film, which affects the production and use of the film. Therefore, this needs to be improved. Utility Model Content

[0029] Reference Figures 1 to 6The present invention provides a further description of an embodiment of a trimming machine for thin film production.

[0030] A film trimming machine includes a support frame 1 and support legs 2, with the support legs 2 fixedly connected to the support frame 1; it also includes: multiple take-up rollers 3 evenly arranged on the support frame 1 and fixedly connected to it; two support cylinders 4 symmetrically arranged on the support frame 1 and fixedly connected to it; a support block 5 fixedly connected to the output end of the support cylinders 4; a support cutter 6 mounted on the support block 5 and fixedly connected to it; and a cleaning mechanism. The cleaning mechanism is placed on the support frame 1 and is used to clean the trimming debris adhering to the film. The cleaning groove 7 is opened on the support frame 1. There are two cleaning blocks 8, which are symmetrically arranged in the cleaning groove 7 and slidably connected to the cleaning groove 7. The cleaning shaft 9 is set on the cleaning block 8 and fixedly connected to the cleaning block 8. The cleaning wheel 10 is rotatably connected to the cleaning shaft 9. The driving component is set on the support frame 1. The moving mechanism is set on the support frame 1 and is used to clean the film debris that falls onto the support frame 1 after trimming.

[0031] Reference Figure 5 In a preferred embodiment, the driving component includes: a driving frame 11, which is disposed on the support frame 1 and fixedly connected to the support frame 1; a motor frame 12, which is fixedly connected to the driving frame 11; a driving motor 13, which is fixedly connected to the motor frame 12; a driving shaft 14, which is fixedly connected to the output end of the driving motor 13; and a rotating component disposed on the driving shaft 14.

[0032] This configuration ensures that when the drive motor 13 is running, it drives the drive shaft 14, which is fixedly connected to the output end of the drive motor 13, to rotate, thereby driving the rotating components to run.

[0033] Reference Figure 5 In a preferred embodiment, the rotating component includes: two rotating blocks 15, which are symmetrically arranged on the drive shaft 14 and threadedly connected to the drive shaft 14; two first rotating shafts 16, which are symmetrically arranged on the rotating blocks 15 and fixedly connected to the rotating blocks 15; a rotating plate 17, which is rotatably connected to the first rotating shafts 16; a second rotating shaft 18, which is rotatably connected to the rotating plate 17; and a sliding component, which is disposed on the drive frame 11.

[0034] This configuration causes the rotating block 15, which is threadedly connected to the drive shaft 14, to rotate, causing the rotating blocks 15 to move away from each other, and causing the rotating plate 17, which is rotatably connected to the first rotating shaft 16, to rotate, thereby driving the sliding component to run.

[0035] Reference Figure 3 and Figure 5In a preferred embodiment, the sliding component includes: a first sliding groove 19, which is formed on the drive frame 11; a second sliding groove 20, which is formed on the drive frame 11; a third sliding groove 21, which is formed on the support frame 1; and two sliding blocks 22, which are symmetrically arranged in the first sliding groove 19, slidably connected to the first sliding groove 19, and fixedly connected to the second rotating shaft 18.

[0036] Reference Figure 1 and Figure 5 In a preferred embodiment, the sliding block 22 is fixedly connected to the cleaning shaft 9 and slidably connected to the second sliding groove 20 and the third sliding groove 21.

[0037] This configuration allows the sliding block 22, which is fixedly connected to the second drive shaft, to slide within the first sliding groove 19, the second sliding groove 20, and the third sliding groove 21. This causes the sliding blocks 22 to move closer together, which in turn moves the cleaning shaft 9, which is fixedly connected to the sliding block 22. This causes the cleaning block 8, which is fixedly connected to the cleaning shaft 9, to slide within the cleaning groove 7 until the cleaning wheel 10 comes into contact with the film, thereby cleaning the film debris adhering to the film.

[0038] Reference Figure 6 In a preferred embodiment, the moving mechanism includes: a moving frame 23, which is disposed on the support frame 1 and fixedly connected to the support frame 1; a moving motor 24, which is fixedly connected to the moving frame 23; a moving shaft 25, which is fixedly connected to the output end of the moving motor 24; and a transmission component, which is disposed on the support frame 1.

[0039] This configuration ensures that when the mobile motor 24 is running, it drives the mobile shaft 25, which is fixedly connected to the output end of the mobile motor 24, to rotate, thereby driving the transmission components.

[0040] Reference Figure 6 In a preferred embodiment, the transmission component includes: a transmission rod 26, which is disposed on the support frame 1 and fixedly connected to the support frame 1; and a transmission plate 27, which is disposed on the transmission rod 26, slidably connected to the transmission rod 26, and threadedly connected to the moving shaft 25.

[0041] This configuration allows the transmission plate 27, which is threadedly connected to the movable shaft 25, to rotate, causing the transmission plate 27 to slide on the transmission rod 26, thereby driving the transmission plate 27 to slide at the bottom of the support frame 1, thus cleaning up the debris that falls from the bottom of the support frame 1.

[0042] Working principle: When in use, the drive motor 13 is started first, which drives the drive shaft 14 fixedly connected to the output end of the drive motor 13 to rotate, causing the rotating block 15 threadedly connected to the drive shaft 14 to rotate. The rotating blocks 15 move away from each other, causing the rotating plate 17 rotatably connected to the first rotating shaft 16 to rotate. This causes the sliding block 22 fixedly connected to the second transmission shaft to slide in the first sliding groove 19, the second sliding groove 20 and the third sliding groove 21, causing the sliding block 22 to move closer to each other. This causes the cleaning shaft 9 fixedly connected to the sliding block 22 to move, causing the cleaning block 8 fixedly connected to the cleaning shaft 9 to slide in the cleaning groove 7 until the cleaning wheel 10 comes into contact with the film, thereby cleaning the film debris adhering to the film.

[0043] Next, the mobile motor 24 is started, which drives the mobile shaft 25, which is fixedly connected to the output end of the mobile motor 24, to rotate. This causes the transmission plate 27, which is threadedly connected to the mobile shaft 25, to rotate. The transmission plate 27 slides on the transmission rod 26, which in turn drives the transmission plate 27 to slide at the bottom of the support frame 1, thereby cleaning up the debris that falls at the bottom of the support frame 1.

[0044] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
