[0002] Coating machines are mainly used for surface coating processes on films, paper, and other materials. This machine coats a roll of substrate with a specific functional adhesive, paint, or ink, then dries it before cutting it into sheets or rewinding it. It uses a specialized multi-functional coating head to achieve various forms of surface coating. During the coating process, the gap between the coating head and the substrate affects the coating quality. If the gap is too large, it will lead to uneven coating; if the gap is too small, it will cause severe wear on the coating head, affecting its service life. Therefore, during the production of the coating head, it is necessary to thoroughly grind the coating head to ensure full adhesion between the coating head and the substrate, guaranteeing processing quality.

[0003] Existing grinding devices require manual clamping and fixing of the coating head during grinding. However, the coating head is generally made of metal and is relatively heavy. It is inconvenient to manually place it inside the grinding device for fixing and disassembly. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-disassembly and replacement coating head grinding device for coating machines, which allows for convenient and rapid disassembly and replacement of the coating head.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0023] 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.

[0024] Reference Figures 2-4 This utility model provides an embodiment of a coating head grinding device for a coating machine that can be quickly disassembled and replaced. It includes a mounting plate 1, with support plates 26 fixedly connected to the lower sides of both the left and right ends of the mounting plate 1. A base plate 2 is fixedly connected to the lower side of the mounting plate 1. Inclined grooves 3 are formed at both the left and right ends of the base plate 2. A sliding bearing plate 4 is provided on the inner side of the mounting plate 1. Straight grooves 5 are formed at both the left and right ends of the bearing plate 4. Movable blocks 6 are slidably connected to the inner sides of the straight grooves 5. A movable rod is fixedly connected to the lower end of the movable block 6. 7. The lower end of the movable rod 7 is movably connected to the inner side of the inclined groove 3. The top of the movable block 6 is fixedly connected to an L-shaped plate 8. A clamp 9 for fixing the coating head is installed on the upper side of the L-shaped plate 8. A movable channel 10 is provided in the middle of the bearing plate 4. An electric push rod 11 is provided inside the movable channel 10. The rear end of the electric push rod 11 is fixedly connected to the rear end of the mounting plate 1. A push plate 12 is fixedly connected to the driving end of the electric push rod 11. The end of the push plate 12 is fixedly connected to the front end of the bearing plate 4.

[0025] The coating head is fixed to the L-shaped plate 8 by the clamp 9. The L-shaped plate 8 is fixedly connected to the movable block 6, which can slide left and right in the straight groove 5. The movable rod 7 at the lower end of the movable block 6 is movably connected to the inclined groove 3 on the base plate 2. When the support plate 4 moves back and forth, the movable rod 7 slides along the inclined groove 3, driving the movable block 6 to move left and right, thereby adjusting the position of the coating head. The support plate 4 is driven to move back and forth by the electric push rod 11. The rear end of the electric push rod 11 is fixed inside the rear end of the mounting plate 1, and the driving end is connected to the inner side of the front end of the support plate 4 through the push plate 12. When the driving end of the electric push rod 11 extends forward, it pushes the support plate 4 forward. At this time, the movable rod 7 slides along the inclined groove 3. The movement causes the two movable blocks 6 located in the middle of the support plate 4 to move along the straight groove 5 to both ends, causing the clamping plate 9 to move to both ends of the support plate 4. When the support plate 4 is exposed from the device and away from the grinding area, the coating head is placed in the upper middle of the support plate 4. Then, the drive end of the electric push rod 11 retracts, causing the support plate 4 to move backward and the clamping plate 9 to move towards the middle, clamping and fixing the coating head. By moving the support plate 4 back and forth, the coating head can be moved forward from the middle of the device, making it easy to replace. At the same time, by moving the support plate 4 back and forth, the clamping plate 9 moves left and right, clamping and fixing the coating head, thus facilitating the disassembly and installation of the coating head.

[0026] Reference Figure 1 and Figure 5 A back plate 17 is fixedly connected to the rear end of the mounting plate 1. An electric slide rail 21 with left and right drive is installed on the lower side of the upper end of the back plate 17. A hydraulic rod 22 is installed on the lower side of the electric slide rail 21. A grinding machine 23 is fixedly connected to the drive end of the hydraulic rod 22. A groove 18 is opened in the middle of the rear end of the back plate 17. A slider 19 that slides left and right is provided on the inner side of the groove 18. A water spray pipe 20 is passed through the middle of the slider 19. A lever 24 is fixedly connected to the outside of the hydraulic rod 22. A slot 25 is opened at the rear end of the lever 24. The front end of the water spray pipe 20 is movably connected to the inner side of the slot 25.

[0027] When the coating head moves below the grinding machine 23, the hydraulic rod 22 is activated to drive the grinding machine 23 to descend. The drive motor on the grinding machine 23 drives the grinding wheel below to rotate and grind the coating head. At the same time, the electric slide rail 21 drives the hydraulic rod 22 and the grinding machine 23 to move left and right to grind the coating head.

[0028] Reference Figure 1 and Figure 5 The left and right ends of the support plate 4 are provided with cavities 13 for storing wastewater. The lower rear end of the support plate 4 is fixedly connected with a drain pipe 14 for discharging wastewater. The upper side of the support plate 4 is provided with a through hole 15 for collecting wastewater. The middle part of the bottom plate 2 is provided with an opening 16 for the lower end of the drain pipe 14 to move back and forth.

[0029] The hydraulic rod 22 drives the water spray pipe 20 and the slider 19 to move left and right inside the slide groove 18 via the toggle plate 24, so that the water spray pipe 20 moves with the movement of the grinder 23. During grinding, water is sprayed onto the grinding wheel and coating head of the grinder 23 through the water spray pipe 20 to cool them down. The water carries the grinding debris through the through hole 15 and is collected in the cavity 13. The drain pipe 14 is used to drain the water and impurities collected in the cavity 13.

[0030] Working principle: During the grinding of the coating head, the electric push rod 11 is activated. The electric push rod 11 drives the support plate 4 forward via the push plate 12, and drives the movable rod 7 to move inside the inclined groove 3. This causes the movable block 6 to move towards both ends inside the straight groove 5, moving the two clamping plates 9 away from each other. After the support plate 4 is away from the grinding area, the coating head is placed in the middle of the upper side of the support plate 4. Then, the electric push rod 11 drives the support plate 4 backward via the push plate 12. At this time, the movable rod 7 moves inside the inclined groove 3, and the movable block 6 moves inside the straight groove 5, thereby moving the clamping plates 9 located at both ends of the support plate 4 towards the middle, thus grinding the coating head. The coating head is clamped and fixed; when the coating head moves to the bottom of the grinding machine 23, the hydraulic rod 22 is activated to drive the grinding machine 23 to descend. The drive motor on the grinding machine 23 drives the grinding wheel below to rotate and grind the coating head. At the same time, the electric slide rail 21 drives the hydraulic rod 22 and the grinding machine 23 to move left and right to grind the coating head. The hydraulic rod 22 drives the water spray pipe 20 and the slider 19 to move left and right inside the slide groove 18 through the toggle plate 24, so that the water spray pipe 20 moves with the movement of the grinding machine 23. During grinding, water is sprayed onto the grinding wheel and coating head of the grinding machine 23 through the water spray pipe 20 for cooling and impurity removal.

[0031] 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.
