[0037] Reference Figure 5The drive assembly includes a motor 9 and a cam 12. The motor 9 is fixedly connected to the bottom of the outer wall of the mounting plate 19 and provides a power source to drive the operation of the entire system. A turntable 10 is fixedly connected to the output end of the motor 9. The turntable 10 converts and transmits the rotational motion of the motor 9. A first eccentric shaft 11 is fixedly connected to one edge of the turntable 10. The first eccentric shaft 11 generates eccentric circular motion under the rotation of the turntable 10. A reciprocating assembly is fixedly connected to the other side of the turntable 10. The reciprocating assembly provides power to the suction assembly. The cam 12 is fixedly connected to the conveyor belt 2, which facilitates the rotation of the cam 12 to drive the conveyor belt 2 to rotate and transport the product. The outer wall of the cam 12 has multiple cam grooves 13. The cam grooves 13 are engaged with the first eccentric shaft 11. Through the engagement between the first eccentric shaft 11 and the cam grooves 13, the cam grooves 13 are rotated during the rotation of the first eccentric shaft 11, thereby realizing the transmission of force.

[0038] Reference Figure 4 The reciprocating assembly includes a second eccentric shaft 14, which is fixedly connected to the edge of the turntable 10 away from the first eccentric shaft 11. This allows the turntable 10 to rotate and drive the second eccentric shaft 14 to perform circular motion. A limit block 15 is fixedly connected to the side of the second eccentric shaft 14 away from the turntable 10. The limit block 15 is used to limit the components on the second eccentric shaft 14. A rotating frame 16 is slidably connected to the outer wall of the second eccentric shaft 14. The rotation of the second eccentric shaft 14 enables the reciprocating drive of the rotating frame 16. A first connecting rod 17 is fixedly connected to the outer wall of the rotating frame 16. The first connecting rod 17 is used to transmit the reciprocating motion of the rotating frame 16.

[0039] Reference Figures 4-6 The cleaning component includes two mounting brackets 23, both of which are fixedly connected to the mounting plate 19. The mounting brackets 23 provide a stable mounting base for the core components of the cleaning component. Slider 24 is slidably connected inside the mounting brackets 23. The slider 24 achieves flexible movement adjustment through the sliding connection design. An internal gear ring 25 is fixedly connected between the two sliders 24. The internal gear ring 25 achieves reciprocating motion through cooperation with the half gear 22. A second connecting rod 26 is fixedly connected to the outer wall of the internal gear ring 25.

The end of the second connecting rod 26 away from the internal gear ring 25 is fixedly connected to the wiping plate 27. The wiping plate 27 is used to clean the surface of the product to be processed.

[0040] Reference Figure 6The output end of the motor 9 is fixedly connected to the first sprocket 20. The rotation of the first sprocket 20 transmits the power of the motor 9 to the second sprocket 21. The second sprocket 21 and the half gear 22 are rotatably connected to the outer wall of the mounting plate 19. The first sprocket 20 and the second sprocket 21 mesh to form a stable gear transmission structure, which further transmits the power of the motor 9 to the half gear 22. The half gear 22 meshes with the internal gear ring 25. Through the linkage between the half gear 22 and the internal gear ring 25, the wiping plate 27 in the cleaning component is driven to reciprocate.

[0041] Reference Figure 7 The suction assembly includes a cylinder 28, which is fixedly connected to the placement plate 8. The cylinder 28 serves as the core structure of the suction assembly and is used to house the piston 29. The piston 29 is also slidably connected inside the cylinder 28. The reciprocating motion of the piston 29 enables the suction or discharge of gas. Two one-way valves 30 are fixedly connected to the outer wall of the cylinder 28. The one-way valves 30 can control the gas flow direction and ensure the one-wayness and stability of the airflow. One of the one-way valves 30 is equipped with a suction pipe 31, which is used to suck up the smoke and dust generated during the processing.

[0042] Reference Figure 8 The filter assembly includes a filter box 32, which is fixedly connected to the placement plate 8. The filter box 32 provides efficient filtration for the processing environment. A filter screen 33 is installed inside the filter box 32, which can effectively intercept dust and particulate matter and prevent dust from entering the one-way valve 30 and causing blockage of the one-way valve 30.

[0043] Reference Figures 4-7 A dust suction plate 35 is fixedly connected to the frame 1. The dust suction plate 35 is used to cover and guide the running path of the suction pipe 31 to prevent dust and impurities from leaking out during the suction process. The end of the suction pipe 31 away from the one-way valve 30 passes through the inside of the filter box 32 and is set inside the dust suction plate 35. The through design of the suction pipe 31 allows the sucked dust to directly enter the filter box 32 for processing, avoiding secondary pollution of dust. A sliding groove 34 is opened on the surface of the support plate 18. The outer wall of the second connecting rod 26 is slidably connected to the inside of the sliding groove 34. The sliding of the second connecting rod 26 inside the sliding groove 34 allows the second connecting rod 26 to run smoothly when driving the cleaning component, effectively reducing motion resistance and wear, thereby extending the service life of the equipment and improving the reliability of operation.

[0044] Reference Figure 1 and Figure 2The laser lithography assembly includes a support column 4, which is fixedly connected to a mounting frame 3. The support column 4 is used to support and carry the laser lithography machine 7, ensuring stability during processing. An adjustment handle 5 is rotatably connected to the top of the support column 4, which can adjust the height of the support column and the laser lithography machine 7 by rotation. A movable column 6 is slidably connected to the outer wall of the support column 4. The movable column 6 achieves precise positioning of the laser lithography machine 7 through a sliding design. The laser lithography machine 7 is fixedly connected to the outer wall of the movable column 6. The laser lithography machine 7 uses a high-energy laser beam to perform high-precision pattern etching or text printing on the label surface, thereby improving processing quality and precision.

[0045] Working principle: When label printing is required, the height of the moving column 6 is adjusted by rotating the adjustment handle 5. After adjustment, the position of the moving column 6 is adjusted so that the laser lithography machine 7 can accurately perform laser lithography on the product. Then, the motor 9 is powered on. After the motor 9 is powered on, it rotates and drives the turntable 10 to rotate. The first eccentric shaft 11 on the turntable 10 drives the cam 12 to rotate through the circumferential motion. The cam 12 further drives the conveyor belt 2 to rotate and transport the product.

[0046] During the product conveying process, the motor 9 will also drive the first sprocket 20 to rotate, and through the meshing with the second sprocket 21, drive the second sprocket 21 to rotate. When the second sprocket 21 rotates, it will drive the half gear 22 to rotate, which will further drive the internal gear ring 25 to slide back and forth. The reciprocating sliding of the internal gear ring 25 will be transmitted to the second sprocket 21 through the second connecting rod 26, and the second sprocket 21 will wipe the product surface.

[0047] Subsequently, the product is conveyed to the marking area by the conveyor belt 2. At this time, the product is marked by the laser lithography machine 7. During the marking process, the motor 9 is in a rotating state. The rotation of the motor 9 will drive the turntable 10 to rotate and drive the second eccentric shaft 14 to rotate, thereby driving the rotating frame 16 to slide back and forth. When the rotating frame 16 slides, it will drive the first connecting rod 17 to slide back and forth. When the first connecting rod 17 slides, it will drive the piston 29 to slide back and forth, thereby increasing or decreasing the air pressure inside the cylinder 28. When the air pressure inside the cylinder 28 decreases, the smoke and impurities generated during the lithography process will be adsorbed by the suction pipe 31 and the dust suction plate 35. At the same time, the impurities will be filtered by the filter screen 33 inside the filter box 32 to prevent clogging of the one-way valve 30.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
