Description

Technical Field

[0001] This utility model relates to the technical field of decorative film cutting mechanisms, specifically a decorative film cutting mechanism. Background Technology

[0002] In today's decorative materials industry, decorative films are increasingly widely used. Whether for wall and furniture surface decoration in home renovation or for creating a unique atmosphere in commercial spaces, decorative films are favored for their diverse colors and convenient construction characteristics. Decorative film is an ultra-thin flexible material made of high molecular polymers (such as PVC, PU, ​​PET, etc.), with a thickness usually between 0.1-0.5mm. It is given rich surface effects through printing, embossing or coating processes.

[0003] During the use of decorative film, it is produced into rolls for easy movement and storage. Then, during use, the decorative film is cut into the required actual size using a cutting mechanism. The cutting mechanism of decorative film usually consists of a bracket, a transmission system, and a blade assembly.

[0004] Currently, when using a decorative film cutting mechanism, it is usually necessary to allow the decorative film to pass through the inside of the cutting structure, then adjust its position according to the actual required size of the decorative film, and then drive the cutting mechanism to move, thereby completing the cutting of the decorative film.

[0005] However, during the cutting process, it is only after the cut end of the decorative film is manually pulled to separate the cut part from the main body that it is known whether the decorative film has been cut and broken. This leads to reliance on manual peeling, which reduces work efficiency. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide a cutting mechanism for decorative film, so as to solve the technical problem that after the cutting is completed, the cut end of the decorative film is manually pulled to separate the cut part from the main body, so as to know whether the decorative film is broken. This leads to the reliance on manual peeling, which reduces work efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cutting mechanism for decorative film, comprising a base, a supporting structure on the top of the base, a connecting block fixedly connected to the top of the base, fixing blocks fixedly connected to both sides of the connecting block, and the top of the fixing block being a sloping structure; a fixing frame fixedly connected to the top of the base; a slider that fits with the connecting block at the bottom of the fixing frame; a connecting member connected to the bottom of the slider via a fixing rod; a cutting device installed at the bottom of the connecting member; a first roller rotatably connected to one side of the connecting member; a set of connecting rods rotatably connected to both ends of the connecting member via a rotating shaft; a coil spring provided at the connection between the rotating shaft and the connecting member; and a second roller that fits with the fixing block rotatably connected to the bottom of the connecting rod.

[0008] By adopting the above technical solution, the decorative film roll to be cut is fixed by the support structure. Then, one end of the decorative film is pulled to pass through the bottom of the fixing frame. The length of the decorative film is adjusted according to the actual needs, and then the decorative film is laid flat on the top of the connecting block in a loose state. At this time, the drive slider at the bottom of the fixing frame drives the cutting device to move, which allows the first roller to move on the top of the connecting block, thereby fixing the decorative film at the cutting position and preventing displacement during the cutting process. During the cutting process, the second roller moves on the top of the fixing block, so that the second roller moves with the change of the inclined surface of the fixing block. After the cutting is completed, the decorative film is pushed to both sides by the movement of the second roller, so that the decorative film is separated after the cutting. The design of the first and second rollers ensures that the decorative film maintains tension at all times during the cutting, ensuring that the decorative film can be cut and separated. It can also quickly separate the cut decorative film from the main body, reduce manual peeling steps, and improve work efficiency.

[0009] The present invention is further configured such that the support structure includes a set of columns, a movable rod and a threaded groove, and a set of columns is fixedly connected to the top of the base, one of the columns is movably connected to the movable rod, the other column is provided with a threaded groove on its surface, and one end of the movable rod moves in the threaded groove.

[0010] By adopting the above technical solution, after the decorative film roll to be cut is located in the middle of a set of columns, the movable rod can pass through the decorative film roll, and the other end of the movable rod is connected to another column through a threaded groove, so that the decorative film roll can move on the surface of the movable rod, making it easy to pull the decorative film according to the actual required length, thereby realizing the cutting of the decorative film.

[0011] The present invention is further configured such that the bottom of the fixing frame is provided with a sliding groove, and a slider that matches the sliding groove is slidably connected in the sliding groove. A threaded rod that matches the slider is rotatably connected in the sliding groove. One end of the threaded rod movably passes through one end of the sliding groove and extends to the outside. A motor that matches the threaded rod is installed at one end of the fixing frame, and the output end of the motor is connected to one end of the threaded rod.

[0012] By adopting the above technical solution, the starting motor drives the threaded rod to move, and the rotation of the threaded rod drives the slider to move in the groove, so that the connecting parts and the cutting device can move synchronously, thereby realizing the cutting of the decorative film.

[0013] The present invention is further configured such that a groove is provided on the top of the connecting block, and the cutting device moves within the groove.

[0014] By adopting the above technical solution, the groove can provide a clear position for the cutting device. When the decorative film to be cut is located at the top of the connecting block, the cutting can be completed by the movement of the cutting device in the groove.

[0015] The present invention is further provided with a rubber pad at the bottom of the base and positioning holes at each of the four corners of the base.

[0016] By adopting the above technical solution, the design of the rubber pad can increase the friction between the base and the contact surface, thereby increasing the stability of the cutting mechanism during operation. At the same time, fixing parts such as bolts can be set in the positioning hole to fix the position of the base, which can further increase the stability of the cutting mechanism.

[0017] The present invention is further configured such that the end of the fixing block closer to the motor is designated as the low end, and the end of the fixing block farther from the motor is designated as the high end.

[0018] By adopting the above technical solution, when the driving slider moves, the second roller can move synchronously on the top of the fixed block. The change of the inclined structure can squeeze the second roller, which makes it easier to push the cut decorative film to move to both sides.

[0019] The present invention is further configured such that the slider is configured as a "T" shaped structure.

[0020] By adopting the above technical solution, the stability of the slider during the sliding process can be increased, preventing the slider from falling out of the groove, thereby making the movement of the cutting device more stable.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention involves laying the decorative film flat on top of a connecting block, then driving a slider and a cutting device to move. This allows the first roller to move on top of the connecting block, fixing the decorative film at the cutting position and preventing displacement during cutting. During cutting, the second roller moves on top of the fixing block, following the slope of the fixing block to push it to both sides, thus separating the decorative film. The design of the first and second rollers ensures that the outer part of the decorative film is always under tension, guaranteeing successful cutting and separation. It also allows for quick separation of the cut decorative film from the main body, reducing manual peeling steps and improving work efficiency. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] A cutting mechanism for decorative film, such as Figure 1-5As shown, the device includes a base 1, with a rubber pad 2 at the bottom of the base 1 to increase the friction between the base 1 and the contact surface, thereby increasing the stability of the cutting mechanism during operation. Positioning holes 3 are provided at the four corners of the base 1. By setting bolts and other fixing parts in the positioning holes 3, the base 1 is connected to the contact surface, which facilitates the fixing of the base 1 and helps to increase the stability of the cutting mechanism during operation.

[0032] A support structure is then provided on the top of the base 1 to fix the decorative film roll to be cut. A connecting block 9 is fixedly connected to the top of the base 1, and fixing blocks 11 are fixedly connected to both sides of the connecting block 9. The top of the fixing block 11 is set as a sloping structure. A fixing frame 7 is fixedly connected to the top of the base 1. A slider 13 that fits with the connecting block 9 is provided at the bottom of the fixing frame 7. The bottom of the slider 13 is connected to a connector 17 through a fixing rod 16. A cutting device 19 is installed at the bottom of the connector 17, so that the slider 13 drives the cutting device 19 to move at the bottom of the fixing frame 7. A first roller 18 is rotatably connected to one side of the connector 17. During the cutting process, the first roller 18 is always in front of the connector 17 and the connecting block 9 advances. Rollers are used to fix the position of the decorative film to be cut, preventing displacement due to external forces during the cutting process and affecting the cutting effect. Both ends of the connector 17 are rotatably connected to a set of connecting rods 21 via a rotating shaft 20, allowing the connecting rods 21 to rotate via the rotating shaft 20. A coil spring 22 is provided at the connection between the rotating shaft 20 and the connector 17, so when the connecting rod 21 is subjected to external force, it can rotate via the rotating shaft 20, and after the external force disappears, it can be reset by the coil spring 22. The bottom of the connecting rod 21 is rotatably connected to a second roller 8 that engages with the fixing block 11, allowing the second roller 8 to move on the top of the fixing block 11. The inclined structure at the top of the fixing block 11 applies external force to the connecting rod 21, thereby changing the position of the second roller 8.

[0033] Meanwhile, the supporting structure includes a set of columns 4, a movable rod 5, and a threaded groove 6. A set of columns 4 is fixedly connected to the top of the base 1. The movable rod 5 is movably connected inside one of the columns 4, and the other column 4 has a threaded groove 6 on its surface. One end of the movable rod 5 moves in the threaded groove 6. When the decorative film roll to be cut is placed between the set of columns 4, the movable rod 5 can be pushed through the middle of the decorative film roll and connected and fixed to the other column 4 through the threaded groove 6, thereby fixing the decorative film roll without affecting the rotation of the decorative film roll on the outer surface of the movable rod 5, which facilitates the cutting of the decorative film according to the actual situation.

[0034] The end of the fixing block 11 closest to the motor 15 is designated as the low end, and the end of the fixing block 11 furthest from the motor 15 is designated as the high end, so that the second roller 8 can move from the low end to the high end on the top of the fixing block 11, thereby better achieving rapid separation of the decorative film from the main body.

[0035] Furthermore, a groove 12 is provided at the bottom of the fixing frame 7. A slider 13 that matches the groove 12 is slidably connected in the groove 12, and the slider 13 is set with a "T" shaped structure. A threaded rod 14 that matches the slider 13 is rotatably connected in the groove 12. One end of the threaded rod 14 moves through one end of the groove 12 and extends to the outside. A motor 15 that matches the threaded rod 14 is installed at one end of the fixing frame 7, and the output end of the motor 15 is connected to one end of the threaded rod 14. When the motor 15 is started, it drives the threaded rod 14 to rotate, thereby driving the slider 13 to move in the groove 12. This allows the cutting device 19 to move synchronously with it to cut the decorative film. At the same time, a groove 10 is provided on the top of the connecting block 9. The cutting device 19 moves in the groove 10, which provides a clear movement space for the cutting device 19. Therefore, when the cutting device 19 moves in the groove 10, it can complete the cutting of the decorative film on the top of the connecting block 9.

[0036] Therefore, in use, the decorative film roll to be cut can be fixed by the support structure, and then one end of the decorative film can be pulled to pass through the bottom of the fixing frame 7. The length of the decorative film can be adjusted according to the actual needs, and then the decorative film to be cut can be laid flat on the top of the connecting block 9. The decorative film is in a loose state. At this time, the drive slider 13 drives the cutting device 19 to move at the bottom of the fixing frame 7, which allows the first roller 18 to move on the top of the connecting block 9, thereby fixing the decorative film at the cutting position and preventing displacement during the cutting process. During the cutting process, the second roller 8 is driven to move on the top of the fixing block 11, so that the second roller 8 moves with the change of the inclined surface of the fixing block 11. After the cutting is completed, the decorative film can be pushed to both sides by the movement of the second roller 8, so that the decorative film can be separated after the cutting. The design of the first roller 18 and the second roller 8 can keep the decorative film under tension at all times during the cutting, ensuring that the decorative film can be cut and separated. It can also quickly separate the cut decorative film from the main body, reduce manual peeling steps, and improve work efficiency.
