[0033] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0034] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a laser film cutting machine, including a workbench 1, the top of the workbench 1 is fixedly connected to two brackets 2, the outside of the bracket 2 is fixedly connected to a motor 9, the output end of the motor 9 is fixedly connected to a bidirectional screw rod 10, the external threaded connection of the bidirectional screw rod 10 is two threaded sleeves 4, one side of the two threaded sleeves 4 is fixedly connected to two moving columns 6, the internal sliding connection of the two moving columns 6 is two sliding rods 5, the bottom of the moving column 6 is fixedly connected to a telescopic rod 11, the opposite side of the two brackets 2 is fixedly connected to a connecting frame 3, and a disassembly component is installed on the top of the workbench 1, which is used to disassemble the tool 21.

[0035] Specifically, the entire structure is provided with stability and support by the workbench 1 and the bracket 2 to ensure that the film cutting machines ensure that they work stably. The motor 9 provides power to drive the bidirectional screw 10 to rotate. When the bidirectional screw 10 rotates, the two threaded sleeves 4 move left and right on the screw to achieve movement toward or away from each other. The movement of the threaded sleeve 4 drives the moving column 6 to move. The slide rod 5 provides a guide for the movement of the moving column 6 to ensure that the moving column 6 moves in a straight line. At the same time, the telescopic rod 11 controls the height of the tool 21 by telescoping to achieve precise positioning. The connecting frame 3 provides movement space for the bidirectional screw 10, thereby allowing the two threaded sleeves 4 to move inside the connecting frame 3.

[0036] Reference Figure 2 and Figure 4 The disassembly includes an installation shell 12, the top of the installation shell 12 is fixedly connected to the bottom of the telescopic rod 11, the inside of the installation shell 12 is slidably connected to a pull rod 16, the outside of the pull rod 16 is provided with a spring 17, one end of the spring 17 is fixedly connected to a movable plate 18, one side of the movable plate 18 is fixedly connected to a block 19, the bottom of the installation shell 12 is slidably connected to a fixed plate 14, the bottom of the fixed plate 14 is fixedly connected to a tool 21, and a groove 20 is provided on the outside of the fixed plate 14.

[0037] Specifically, under the elastic force of the spring 17, the block 19 can automatically be stuck in the groove 20 of the fixed plate 14, so that the fixed plate 14 and the tool 21 at the bottom thereof can be stably locked at the bottom of the mounting shell 12, ensuring that the tool 21 will not be displaced due to vibration or external force during the film cutting process, thereby ensuring the accuracy and stability of the film cutting. By pulling the handle 15, the pull rod 16 can be driven to move, thereby compressing the spring 17 and driving the movable plate 18 to move. The movement of the movable plate 18 will cause the block 19 to move out of the groove 20, releasing the lock on the fixed plate 14. At the same time, the design of the telescopic rod 11 allows the entire film cutting assembly to be telescopically adjusted in the vertical direction to adapt to laser films of different thicknesses or heights, thereby increasing the adaptability and flexibility of the equipment.

[0038] Reference Figure 3 The end of the bidirectional screw rod 10 is rotatably connected to the inside of the connecting frame 3, and the outside of the threaded sleeve 4 is slidably connected to the inside of the connecting frame 3. A feed roller 7 is fixedly connected to one side of the top of the workbench 1, and a receiving roller 8 is fixedly connected to the other side.

[0039] Specifically, the connecting frame 3 provides a stable support and rotation platform for the bidirectional screw 10. When the threaded sleeve 4 moves on the bidirectional screw 10, its outer portion can be guided and supported by the connecting frame 3 to ensure the smoothness and accuracy of the movement. The function of the feed roller 7 is to feed the laser film to be cut into the working area of ​​the film cutting machine to ensure that the laser film can be cut smoothly and continuously by the film cutting blade. The function of the receiving roller 8 is to collect the cut laser film to ensure that the cut products can be collected neatly and orderly for subsequent processing and packaging.

[0040] Reference Figure 1 The two ends of the sliding rod 5 are fixedly connected to the outside of the bracket 2, and the two sides of the bottom of the mounting shell 12 are fixedly connected with the smoothing plate 13. One end of the pull rod 16 extends to the outside of the mounting shell 12 and is provided with a handle 15. The other end of the spring 17 is fixedly connected to the inside of the mounting shell 12. The outside of the movable plate 18 is slidably connected to the inside of the mounting shell 12, and the outside of the block 19 is inserted into the inside of the groove 20.

[0041] Specifically, the slide bar 5 provides a stable sliding track for the moving column 6, ensuring that the moving column 6 can move smoothly in the horizontal direction. The function of the smoothing plate 13 may be to level or support the material to be cut to ensure the accuracy and quality of the cutting. The handle 15 is convenient for the user to operate. By pulling the handle 15, the user can easily move the pull rod 16. The spring 17 provides elastic force for the entire locking and unlocking mechanism, ensuring that the block 19 can be stably inserted into or moved out of the groove 20. When the moving plate 18 drives the block 19 to insert into the groove 20, the fixed plate 14 and the tool 21 thereon are locked; when the block 19 is moved out of the groove 20, the fixed plate 14 and the tool 21 can be disassembled.

[0042] Working principle: When the motor 9 is started, it drives the bidirectional screw 10 to rotate. The rotation of the bidirectional screw 10 causes the two threaded sleeves 4 connected to it to move left and right on the screw. The movement of the threaded sleeve 4 drives the movable column 6 fixedly connected to it to move left and right under the guidance of the slide rod 5. At the same time, under the extension and contraction of the telescopic rod 11, the height of the tool 21 can be controlled. By driving the bidirectional screw 10 to rotate forward and backward and the speed of rotation by the motor 9, the moving distance and speed of the film cutting blade can be accurately controlled, thereby achieving accurate cutting of the laser film.

[0043] Secondly, the block 19 is stuck in the groove 20 of the fixed plate 14 under the elastic force of the spring 17, and the fixed plate 14 is therefore locked at the bottom of the mounting shell 12. The tool 21 is fixed to the bottom of the fixed plate 14 and is locked together with the fixed plate 14, so that the film cutting operation can be performed stably. When the tool 21 needs to be removed, the handle 15 is pulled by external force to drive the pull rod 16 to move, so that the spring 17 compresses the tension and drives the movable plate 18 to move, thereby moving the block 19 out of the groove 20, losing the lock of the block 19, and the fixed plate 14 drives the tool 21 to slide out at the bottom of the mounting shell 12, thereby realizing disassembly.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
