Description

Technical Field

[0001] The invention relates to the technical field related to sandpaper production, in particular to an adsorption-type positioning device for sandpaper gluing. Background Art

[0002] Sandpaper refers to a kind of paper or cloth with abrasive particles connected by a durable adhesive. It is widely used as a tool for grinding, polishing and grinding the surface of objects. When processing objects such as metal, wood and walls, sandpaper can remove protrusions or burrs on the surface of objects to make the surface of objects smoother. The production and processing of sandpaper includes many steps, including gluing the base paper used for sandpaper production, spreading sand particles, drying and cutting, etc. In the process of gluing the sandpaper base paper, the sandpaper base paper needs to be positioned;

[0003] With reference to patent application publication number CN114558745A, the application publication date is 2022.05.31, which discloses a paper surface gluing device and a gluing process for sandpaper production, which belongs to the field of sandpaper production technology, and includes a workbench, a fixed component, a scraping component and a gluing component. The fixed end of the fixed component is slidably matched with the workbench, the scraping component is arranged on the workbench and the scraping component is located above the fixed component, and the gluing component is arranged on a movable structure. The present invention fixes the base paper on the workbench by a fixed component to avoid the displacement of the base paper during the gluing process affecting the gluing effect. The movable structure of the scraping component drives the gluing component to move back and forth, and the gluing component glues the base paper. The movable structure continues to drive the scraping structure to move back and forth to scrape the glue on the base paper. By adjusting the distance between the scraping structure and the base paper, the glue on the base paper is scraped and the amount of glue retained on the base paper is controlled to avoid excessive glue from penetrating the base paper and affecting the later sandpaper production.

[0004] Reference patent application publication number 202321770741.9, application publication date 2023.07.07, discloses a gluing device for sandpaper base paper production, including a workbench, U-shaped frames are arranged on both sides above the workbench, a screw is threadedly connected to the middle part of the upper part of the U-shaped frame, a turntable is fixedly connected to the upper end of the screw, a pressing plate is rotatably connected to the lower end of the screw, a fourth slot is arranged on the inner side of the U-shaped frame, a third slider is fixedly connected to one end of the pressing plate, and the third slider is slidably connected to the inside of the fourth slot, and the U-shaped frame, the screw and the pressing plate are arranged to clamp and fix the two ends of the sandpaper base paper, so as to ensure the stability of the sandpaper during gluing, and there will be no deviation and poor manual pressing effect, and at the same time, a driving motor and a bidirectional screw are arranged to enable the threaded block to drive the two clamping assemblies above to move relative to each other, so as to clamp sandpaper base papers of different sizes, thereby increasing the practicality and convenience of the device;

[0005] However, the existing sandpaper gluing device still has the following shortcomings:

[0006] 1. The existing sandpaper gluing device, when gluing the sandpaper base paper, mostly directly presses and fixes the sandpaper, and the sandpaper base paper is usually in a roll, which is inconvenient to transport the base paper and to process the base paper in batches. The pressing and fixing easily makes it inconvenient to perform the gluing operation on the pressing and clamping position of the sandpaper base paper, and the actual gluing effect is not uniform enough;

[0007] 2. The existing sandpaper gluing device is not convenient for positioning base papers of different sizes, and the sandpaper base paper is prone to offset or skew during the gluing process, which affects the stability of the sandpaper base paper during the gluing process;

[0008] 3. In the existing sandpaper gluing device, the flatness of the sandpaper base paper is poor during the gluing process, which easily causes the gluing position to be easily arched and warped. The positioning effect of the sandpaper gluing position needs to be improved urgently.

The roller 16 installed at the lower end of the connecting long plate 15 and the movable block 17 fixedly connected to the side of the connecting long plate 15 first slide between the linkage block 22 and the adjustment plate 19 according to the size of the sandpaper base paper, and the linkage block 22 is fixed to the movable end of the spring 21, and the linkage block 22 squeezes the spring 21, so that the spring 21 undergoes elastic deformation, and the linkage block 22 is fixedly connected to the positioning pin 23, and the linkage block 22 drives the positioning pin 23 to extend and retract, so that the positioning pin 23 is disengaged from the fixing hole 24, thereby releasing the limit between the adjustment plate 19 and the support plate 18;

[0050] Then, according to the size of the sandpaper base paper, the adjusting plate 19 is pushed, the adjusting plate 19 slides with the supporting plate 18, and the adjusting plate 19 drives the limit block 25 to slide with the supporting plate 18, thereby improving the sliding stability between the adjusting plate 19 and the supporting plate 18, and the upper end of the adjusting plate 19 is fixedly connected with an auxiliary bracket 20, and the upper end of the auxiliary bracket 20 is fixedly connected with the anti-deviation plate 12. During the sliding process of the adjusting plate 19 and the supporting plate 18, the adjusting plate 19 drives the anti-deviation plate 12 to extend and retract at the upper end of the positioning seat 1 through the auxiliary bracket 20, thereby facilitating the anti-deviation of the front and rear sides of the upper end of the positioning seat 1 The spacing between the plate 12 and the anti-deviation plate 12 is adjusted so that the spacing between the anti-deviation plate 12 at the upper end of the positioning seat 1 and the anti-deviation plate 12 is equal to the width of the sandpaper base paper.

The fixing cap 8 connected to the outer surface of the fixing rod 7 by rotating the thread is fitted between the fixing cap 8 and the movable push plate 9. The fixing cap 8 drives the movable push plate 9 to slide between the fixing rod 7. The middle part of the movable push plate 9 is fixedly connected with a fixing pin 10. The movable push plate 9 drives the fixing pin 10 to extend and retract between the mounting block 4, so that the fixing pin 10 is inserted into the mounting groove 6 at the corresponding position on the mounting bracket 5, which is convenient for limiting the mounting block 4 and the mounting bracket 5. Then the reduction motor 31 is started. The reduction motor 31 drives the lower conveying clamping roller 2 to rotate slowly on both sides of the positioning seat 1, so as to facilitate the clamping and conveying of the sandpaper base paper.

[0052] The cam 15 is provided with a plurality of movable blocks 17, and the movable blocks 17 are provided on the sides of the plurality of movable blocks 17. The ...

[0053] When the sandpaper base paper is transported to the middle of the positioning seat 1, the sandpaper base paper is coated with glue by the glue coating component installed in the middle of the upper end of the positioning seat 1, and in the actual transportation and gluing process, the sandpaper base paper is coated with glue. Figure 1 and Fig.12As shown, an adsorption assembly 26 is provided in the middle of the positioning seat 1, and the adsorption assembly 26 is arranged in the middle of the positioning seat 1, and the adsorption assembly 26 includes a suction device 27 fixedly installed on the front and rear sides of the middle of the positioning seat 1, a suction hood 28 arranged in the middle of the positioning seat 1, and a suction groove 29 equidistantly arranged in the middle of the upper end of the positioning seat 1. The suction device 27 is started, and the suction device 27 sucks air through the suction hood 28, and the suction hood 28 is arranged at the lower end of the suction groove 29, so that the sandpaper base paper in the middle of the positioning seat 1 can be adsorbed and fixed, thereby preventing the sandpaper base paper from warping or arching during the gluing and conveying process, thereby achieving a better gluing effect, and having high practicality. At the same time, the adsorption force on the sandpaper base paper is smaller than the conveying force of the lower conveying roller 2 and the upper conveying roller 3 at the left and right ends of the positioning seat 1 on the sandpaper base paper, so that the adsorption will not affect the conveying of the sandpaper base paper.
