[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, capable of significant deformation under small external forces, and returns to its original shape after the force is removed. Rubber is a completely amorphous polymer. There are two types of rubber: natural rubber and synthetic rubber. Natural rubber is made by extracting latex from plants such as rubber trees and rubber grass; synthetic rubber is obtained by polymerizing various monomers. Rubber products are widely used in various aspects of industry and daily life.

[0003] Existing film cutting devices typically require multiple operations during use, and the cutting blade is often difficult to store after cutting. To address these issues, we propose a film cutting device with guiding and centering capabilities. Utility Model Content

[0004] The purpose of this invention is to provide a film cutting device with guiding and centering capabilities to solve the problems mentioned in the background art.

[0010] Preferably, the ends of the two B-screws are respectively provided with a cross member and a cross groove, and the cross member is engaged in the cross groove.

[0011] Preferably, the main component includes a base, a fixed seat, and a rotating disk, wherein the fixed seat is mounted on the base, and the rotating disk is rotatably mounted on the fixed seat.

[0012] Preferably, the moving component further includes a motor, which is mounted on the base. The output end of the motor is connected to lead screw A, which passes through and extends out of the surface of the fixed base. Both brackets are slidably disposed on the base.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. When cutting film, cutting can be performed using cutting components. During this process, the cutting efficiency can be improved by using two symmetrically arranged cutting components. During the first cut, the two mounting plates will move outward to cut the sheet film into strips. Then, the rotating disk will rotate the film. After rotating 90°, the cutting components will move in the opposite direction, causing the two mounting plates to move inward to cut the strip film into small rectangular sheet structures. With this setup, the film can be quickly cut in just two cutting operations, and the cutting device can be positioned in the center of the device after cutting.

[0019] 2. To prevent the rotating disk from colliding with the two supports during rotation, the two supports can be connected by a lead screw (A). Rotating the lead screw (A) allows the two supports to move relative to each other, thus keeping them away from each other during rotation and preventing collisions. After rotation, the lead screw (A) can be rotated in the opposite direction to return the two supports to their original positions. This design allows the device to occupy a smaller area during daily use. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a film cutting device with guiding and centering capabilities, including a main body component 1, a moving component 2 and a fixing component 4 installed on the main body component 1, and a cutting component 3 installed on the moving component 2.

[0028] The movable component 2 includes a lead screw 22 and a bracket 23. There are two brackets 23, and both brackets 23 are on the main component 1. The two brackets 23 are symmetrically arranged, and the lead screw 22 is threadedly connected to the two brackets 23.

[0029] The cutting assembly 3 includes a movable part 31, a mounting plate 32, a cutting device 33, and a B-screw 34. A limiting groove is provided on the bracket 23. The movable part 31 and the B-screw 34 are both set in the limiting groove. The movable part 31 is threaded onto the B-screw 34. The mounting plate 32 is mounted on the movable part 31. The cutting device 33 is mounted on the mounting plate 32.

[0030] There are two cutting components 3, and the two cutting components 3 are symmetrically arranged and respectively set on two brackets 23.

[0031] Specifically, when cutting the film, the film is first placed on the main component 1. At this time, the B screw 34 can be rotated to drive the moving part 31 to move, which in turn drives the mounting plate 32 and the cutting device 33 to move. During the movement of the cutting device 33, the film can be cut. In actual use, the film is usually placed on the rotating disk 13. After the first cut is completed, a second cut is required. When performing the second cut, the rotating disk 13 needs to be rotated. In order to avoid the rotating disk 13 from colliding with the bracket 23, the A screw 22 can be rotated to change the position of the two brackets 23. After the rotating disk 13 is rotated, the A screw 22 can be rotated in the opposite direction to return the bracket 23 to its original position.

[0032] In this embodiment, the ends of the two B screws 34 are respectively provided with a cross member and a cross groove, and the cross member is engaged in the cross groove.

[0033] Specifically, during use, an external motor can be connected to lead screw 34 B, enabling lead screw 34 to rotate automatically. In use, a cross-shaped component can be set at the end of one lead screw 34, and a cross groove can be set at the end of the other lead screw 34. The cross-shaped component is engaged in the cross groove, so that a single external motor can rotate both lead screws 34.

[0034] In this embodiment, the main component 1 includes a base 11, a fixed seat 12 and a rotating disk 13. The fixed seat 12 is mounted on the base 11, and the rotating disk 13 is rotatably mounted on the fixed seat 12.

[0035] Specifically, in actual use, the rotating disk 13 is rotatably mounted on the fixed seat 12, so that the film can be rotated during secondary cutting. The fixed seat 12 is fixedly installed on the base 11, which facilitates the subsequent passage of the lead screw 22 through the fixed seat 12 to connect the two brackets 23.

[0036] In this embodiment, the moving component 2 also includes a motor 21, which is mounted on the base 11. The output end of the motor 21 is connected to the lead screw 22 A, which passes through and extends out of the surface of the fixed seat 12. Both brackets 23 are slidably disposed on the base 11.

[0037] Specifically, in use, a motor 21 can be installed on the base 11, and the output end of the motor 21 can be connected to the lead screw 22 A. Thus, by starting the motor 21, the lead screw 22 A can be rotated.

[0038] In this embodiment, the cutting device 33 consists of multiple cutting blades, and the surface of the rotating disk 13 is provided with multiple cutting grooves, with the positions of the multiple cutting blades corresponding to the positions of the multiple cutting grooves.

[0039] Specifically, in order to improve cutting efficiency, the cutting device 33 is composed of multiple cutting blades, and each cutting blade corresponds to the position of the cutting groove, so that the cutting blade can always move within the cutting groove when the cutting device 33 moves.

[0040] In this embodiment, the fixing component 4 includes an A fixing member 41 and an A connecting member 42. There are two A connecting members 42, and both A connecting members 42 are mounted on the rotating disk 13. The A fixing member 41 is rotatably disposed between the two A connecting members 42. The fixing component 4 also includes a B fixing member 43 and a B connecting member 44. There are two B connecting members 44, and both B connecting members 44 are mounted on the rotating disk 13. The B fixing member 43 is rotatably disposed between the two B connecting members 44.

[0041] Specifically, when placing the film, in order to prevent the film from moving during subsequent cutting, the four sides of the film can be fixed by fixing part A 41 and fixing part B 43. The film can be pressed by fixing part A 41 and fixing part B 43. Fixing part A 41 is set between two connecting parts A 42 and fixing part B 43 is set between two connecting parts B 44. The position of fixing part A 41 and fixing part B 43 can be controlled by rotation, thereby controlling whether the film is pressed.

[0042] In this embodiment, the B fixing member 43 and the A fixing member 41 have the same shape, and the length of the B fixing member 43 is less than that of the A fixing member 41.

[0043] Specifically, in order to prevent the A fixing member 41 and the B fixing member 43 from colliding with each other during rotation, the length of the B fixing member 43 is less than the length of the A fixing member 41.

[0044] The working principle and usage process of this utility model are as follows: When cutting the film, the film can be placed on the rotating disk 13 and the position of the film can be fixed by the fixing component 4. At this time, the film can be efficiently cut by running two cutting components 3. After the first cutting is completed, the motor 21 is run to make the two supports 23 move away from each other. Then the rotating disk 13 is rotated. After the rotating disk 13 is rotated 90°, the motor 21 is run in reverse to return the supports 23 to their positions. Then the cutting components 3 are run in reverse to cut the film a second time. After the second cutting is completed, both cutting devices 33 are set at the center position of the device.

[0045] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
