Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to an automated gluing device for sandpaper processing. Background Technology

[0002] Sandpaper is a type of coated abrasive tool made of paper or fabric as the base material, with abrasives such as alumina and silicon carbide evenly attached, and bonded and cured through a special process. It is used for grinding, polishing, rust removal and roughness treatment of material surfaces.

[0003] In the manufacturing of abrasive tools and various grinding materials, sandpaper usually needs to be coated with adhesive to firmly bond the abrasive, improve the service life and grinding performance of the sandpaper. Automated adhesive coating equipment for sandpaper processing can precisely control the amount and position of adhesive, achieve efficient and uniform adhesive coating, and greatly improve production efficiency and product quality consistency.

[0004] However, existing automated glue-applying devices for sandpaper processing have the following shortcomings:

[0005] In the existing technology, automated gluing devices for sandpaper processing can usually only perform gluing operations on sandpaper base paper of a specific size. However, the length and width of different sandpapers are not uniform and there are significant differences. Existing devices lack an effective size adaptation and fixing mechanism, making it inconvenient to securely fix sandpaper of different sizes. As a result, the sandpaper is prone to shifting during the gluing process, leading to deviations in the glue spraying position and ultimately affecting the quality of the gluing.

[0006] Therefore, we propose an automated glue-applying device for sandpaper processing to solve the problems mentioned above. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

A first motor 6 is fixedly connected to the bottom of the rotating shaft 5. A gear 7 is fixedly fitted onto the outer wall of the rotating shaft 5. Two racks 8 are meshed onto the outer walls of the gear 7. The top of the operating table 1 is fixedly equipped with... There are two second slide rails 9, and the outer walls of the two second slide rails 9 are movably fitted with second sliders 10. The tops of the two first sliders 3 and the two racks 8 are fixedly connected with fixed frames 11. The tops of the two fixed frames 11 are fixedly connected with cylinders 12, and the telescopic ends of the two cylinders 12 are movably inserted into the interior of the two fixed frames 11. The telescopic ends of the two cylinders 12 are fixedly connected with pressure plates 13. The tops of the two pressure plates 13 are fixedly connected with a set of guide rods 14, and the outer walls of the two sets of guide rods 14 are movably inserted into the interior of the two fixed frames 11.

[0027] The effect achieved by the entire embodiment 1 is as follows: during use, the first motor 6 is started according to the length of the sandpaper to be coated. The output end of the first motor 6 drives the rotating shaft 5 and the gear 7 to rotate. Since the outer wall of the gear 7 is meshed with the outer wall of the two racks 8, the rotation of the gear 7 will drive the two racks 8 to move in opposite directions. With the guidance of the sliding component, the two racks 8 will then drive the two fixed frames 11 to move synchronously, so that the two pressure plates 13 are in the appropriate positions on both sides of the sandpaper. At this time, the two cylinders 12 are started, and their telescopic ends drive the two pressure plates 13 to move toward the sandpaper, thereby firmly clamping the sandpaper and preventing it from shifting during the coating process, ensuring the accurate spraying position of the adhesive, and thus improving the coating quality.

[0028] Example 2, as Figure 2-5As shown, the top of the operating table 1 is provided with a slide groove 15. A third slider 16 is slidably embedded in the inner wall of the slide groove 15. A threaded rod 17 is threadedly connected to the inner wall of the third slider 16. A second motor 18 is fixedly connected to one side of the outer wall of the threaded rod 17. Two second bearings 19 are fixedly sleeved on the outer wall of the threaded rod 17. An L-shaped fixing plate 20 is fixedly connected to the top of the third slider 16. A third slide rail 21 is fixedly installed on the top of the L-shaped fixing plate 20. A movable frame 22 is fixedly sleeved on the outer wall of the third slide rail 21. Two fourth slide rails 23 are fixedly installed on the outer wall of the movable frame 22. A sliding frame 24 is movably fitted between the outer walls of the two fourth slide rails 23. A glue brush 25 is fixedly connected to the bottom of the sliding frame 24, and a first electric push rod 26 is fixedly connected to the top of the sliding frame 24. A second electric push rod 27 is fixedly connected to one side of the outer wall of the movable frame 22. A glue delivery pipe 28 is fixedly connected to the input end of the glue brush 25. A connecting hose 29 is fixedly connected to the input end of the glue delivery pipe 28. A glue pump 30 is fixedly connected to the input end of the connecting hose 29. A glue outlet pipe 31 is fixedly connected to the input end of the glue pump 30. A melt tank 32 is fixedly connected to the input end of the glue outlet pipe 31.

[0029] The effect achieved by the entire embodiment 2 is as follows: During use, after the sandpaper is fixed, the second motor 18 is started, and its output shaft drives the threaded rod 17 to rotate. Based on the thread transmission principle, the rotation of the threaded rod 17 drives the third slider 16 to move horizontally in the slide groove 15. The third slider 16 then drives the L-shaped fixing plate 20 and the glue brush 25 to move synchronously. Through the reciprocating motion of the glue brush 25, glue can be evenly applied to sandpaper of different lengths. At the same time, the second electric push rod 27 is started, and its telescopic end drives the moving frame 22 to move horizontally along the third slide rail 21, thereby adjusting the position of the glue brush 25 in the horizontal direction. After the glue is applied to part of the sandpaper, the glue is applied to another part of the sandpaper by moving the position of the glue brush 25, so that the glue application operation of sandpaper of different widths can be carried out comprehensively and accurately.

[0030] The working principle of the entire device is as follows: First, place the sandpaper on top of the operating table 1. Then, start the first motor 6 according to the length of the sandpaper to be coated. The output of the first motor 6 drives the rotating shaft 5 and gear 7 to rotate synchronously. The rotation of gear 7 drives two racks 8 to move in opposite directions. Under the support and guidance of the two first slide rails 2 and two first sliders 3, the two racks 8 drive the two fixed frames 11 to move synchronously, so that the two pressure plates 13 accurately reach the appropriate positions on both sides of the sandpaper. At this time, start the two cylinders 12, whose telescopic ends push the two pressure plates 13 closer to the sandpaper, thus firmly clamping the sandpaper and preventing it from shifting during the coating process. Subsequently, start the glue pump 30 and the first electric push rod 26. The telescopic end of the first electric push rod 26 drives the sliding frame 24 to move downwards, so that the bottom of the glue brush 25 is tightly attached to the top of the sandpaper. Simultaneously... The glue pump 30 is started, extracting and pressurizing the glue in the glue tank 32. The glue is then delivered to the glue brush 25 through the glue delivery pipe 28 to begin the glue application. Next, the second motor 18 is started, and its output shaft drives the threaded rod 17 to rotate. The rotation of the threaded rod 17 causes the third slider 16 to move horizontally within the slide groove 15. The third slider 16 drives the L-shaped fixing plate 20 and the glue brush 25 to move synchronously. Through the reciprocating movement of the glue brush 25, glue can be evenly applied to sandpaper of different lengths. Furthermore, by starting the second electric push rod 27, its telescopic end drives the moving frame 22 to slide horizontally along the third slide rail 21, thereby adjusting the horizontal position of the glue brush 25. After one area of ​​the sandpaper has been glued, the position of the glue brush 25 is moved to apply glue to another area of ​​the sandpaper, thus enabling comprehensive and efficient glue application for sandpaper of different widths.
