Description

Technical Field

[0001] This utility model relates to an adjustable film cutting device, belonging to the field of film cutting technology. Background Technology

[0002] A film cutting device is a machine used to cut film materials to specific sizes and shapes. Film cutting devices are commonly used in food packaging, medical device packaging, and industrial applications, improving production efficiency and product quality.

[0003] Although current cutting devices can meet the routine cutting needs of films, two major problems exist in actual operation. First, the film is prone to wrinkling during transport, which not only affects the appearance quality of the film but also leads to dimensional deviations and uneven edges in the cut product, greatly reducing the accuracy and quality of cutting and significantly diminishing the overall effectiveness of the device. Second, in the cutting stage, the lack of an effective limiting mechanism causes the film to easily shift position under force, resulting in inaccurate cutting positions, frequent defects, and seriously affecting the stability and reliability of the cutting device, thus making the device unreliable in use.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] This utility model provides an adjustable film cutting device.

[0027] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes a frame 1, which is the main body of the cutting device. A placement roller 2 is provided on one side of the frame 1 to place the uncut film roll. Two conveying rollers 3 with clearance fit are provided in the middle of the frame 1 to convey the film. Sliding grooves 12 are provided on both sides of the frame 1. A discharge groove 13 is provided in the middle of the frame 1. A fixing frame 4 is fixed in the middle of the upper end of the frame 1. A cylinder 5 is fixed in the middle of the fixing frame 4. A mounting frame 6 is fixed at the driving end of the cylinder 5. A cutting blade 7 is detachably installed in the middle of the mounting frame 6 by bolts. A connecting structure is provided on one side of the mounting frame 6. The connecting structure includes two fixing blocks 8. A connecting frame 9 is rotatably connected to one end of each of the two fixing blocks 8. A sliding frame 10 is rotatably connected to the other end of each of the two connecting frames 9. A moving roller 11 is fixed in the middle of each of the two sliding frames 10.

[0028] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4It is worth noting that the two fixed blocks 8 are fixed to one end of the mounting frame 6 on one side. The cross-section of the two fixed blocks 8 is U-shaped. The upper ends of the two connecting frames 9 are rotatably connected to one end of the two fixed blocks 8. The lower ends of the two connecting frames 9 are rotatably connected to the upper ends of the two sliding frames 10. The outer surfaces of the two sliding frames 10 are slidably connected to the inner walls of the two sliding grooves 12. The vertical cross-section of the two sliding frames 10 is T-shaped. The two ends of the moving roller 11 are fixed to the adjacent sides of the two sliding frames 10.

[0029] In use, the film on the placement roller 2 is first smoothly conveyed to the space between two sliding grooves 12 by two conveying rollers 3 with a clearance fit. Then, the conveying rollers 3 stop rotating. Next, the mounting frame 6 is driven by the cylinder 5 to move downwards. At this time, the cutting blade 7, detachably mounted on the mounting frame 6 by bolts, moves downwards synchronously. Simultaneously, two fixing blocks 8 fixedly connected to one side of the mounting frame 6 also move downwards. During the downward movement, the two fixing blocks 8, through two connecting frames 9 rotatably connected to one end, drive the two sliding frames 10 to begin sliding under the limiting constraint of the sliding grooves 12.

[0030] Driven continuously by cylinder 5, the two sliding frames 10, limited by the inner wall of the slide groove 12, move downwards first, causing the moving rollers 11 fixed on the adjacent sides of the two sliding frames 10 to press tightly against the film. As cylinder 5 continues to move downwards, the two sliding frames 10, guided by the inner walls of the two slide grooves 12, begin to move laterally. During this process, the two laterally moving sliding frames 10 drive the moving rollers 11 fixed on their adjacent sides to move laterally synchronously. Until the moment the cutting blade 7 cuts the film, the two sliding frames 10, along with the moving rollers 11, quickly leave the film surface.

[0031] After cutting, cylinder 5 drives mounting frame 6 to move cutting blade 7 slightly upward. Simultaneously, two conveying rollers 3 begin to operate, transporting subsequent film between two chutes 12. The newly conveyed film pushes the already cut film, causing it to fall from discharge chute 13 to the other side of frame 1. Through this series of continuous actions, automatic leveling is achieved, effectively preventing wrinkles in the film during transport, which would affect the cutting effect, thus improving the efficiency of the cutting device.

[0032] Example 2

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on Example 1, a function for stabilizing pressure has been added;

[0034] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that two stabilizing frames 14 are fixed on both sides of the mounting frame 6. Each stabilizing frame 14 has a support frame 15 slidably connected to its inner wall. Each support frame 15 has a spring 16 fixed to its upper end. One of the pressing frames 17 is fixed to the lower end of each of the two support frames 15. The upper sides of the two stabilizing frames 14 are fixed to both ends of one side of the mounting frame 6. The outer surface of each support frame 15 is slidably connected to the inner wall of each stabilizing frame 14. The vertical cross-section of each support frame 15 is T-shaped. The upper ends of the two pressing frames 17 are fixed to the lower ends of the four support frames 15. The two pressing frames 17 are set on both sides of the cutting blade 7. The lower end of each spring 16 is fixed to one end of each support frame 15, and the upper end of each spring 16 is fixed to the upper inner wall of each stabilizing frame 14.

[0035] In use, this invention works as follows: the cylinder 5 drives the mounting frame 6 to move downwards, and the stabilizing frames 14 fixed on both sides of the mounting frame 6 move downwards synchronously. During the downward movement of the stabilizing frames 14, the support frame 15, which is slidably connected to its inner wall, is also driven to move downwards. The moving support frame 15 causes the pressing frame 17, which is fixed at its lower end, to come into contact with the film first. At this time, under the support of the film and the frame 1, the pressing frame 17 remains stationary. Meanwhile, the cylinder 5 continues to drive the mounting frame 6 and the cutting blade 7, which is detachably mounted on the middle of the mounting frame 6 via bolts, to continue moving downwards. As the mounting frame 6 moves further downwards, the stabilizing frame 14 begins to compress the spring 16 fixed on it. The spring 16 generates elastic force after being compressed, and this elastic force gradually presses the film tightly against the frame 1. In this way, the film can be stably pressed during the cutting process, achieving a stable pressing effect and effectively avoiding positional displacement due to force, thereby improving the stability of the cutting device.
