Description

Technical Field

[0001] This utility model relates to the field of abrasive cloth processing technology, and in particular to an abrasive cloth coating device that provides uniform coating. Background Technology

[0002] Sandpaper and abrasive cloth are the oldest and most widely used coated abrasives, and are used extensively in various manual sanding operations.

[0003] During the processing of sandpaper, the sandpaper parameters and brand name are printed on one side, and resin glue needs to be applied to the other side, requiring the use of a sandpaper glue applicator.

[0004] A coating device for abrasive cloth with uniform coating capability, application number CN202420818146.6, includes a support frame; two mounting brackets fixedly installed on the top of the support frame; a mounting shaft rotatably mounted on the two mounting brackets; a coating roller fixedly sleeved on the mounting shaft, the coating roller being used to coat the processed abrasive cloth with adhesive; a drive motor mounted on one side of the mounting brackets, the output shaft of the drive motor being fixedly connected to one end of the mounting shaft; and a placement box fixedly installed on the two mounting brackets, the placement box being used to place the resin adhesive used in the abrasive cloth processing, the bottom of the placement box being equipped with a discharge box, the bottom of the discharge box having multiple discharge holes for dripping the resin adhesive onto the coating roller. The coating device for abrasive cloth with uniform coating capability provided by this solution can perform uniform coating operations on abrasive cloth, effectively improving the coating effect of abrasive cloth. The device uses a roller coating method to apply the adhesive, and the resin adhesive is dripped onto the coating roller through the adhesive discharge hole. This method is prone to uneven distribution of adhesive on the roller surface, resulting in an excessively thin adhesive layer or accumulation in the sandpaper. There is a large difference in adhesive layer thickness between the edge and the center of the sandpaper. In addition, the placement box is placed on top of the device, and impurities can easily enter the placement box, which can easily cause the adhesive discharge hole to be blocked, affecting the normal operation of the device.

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-3As shown in the figure, this utility model embodiment proposes a uniformly coated abrasive cloth adhesive applicator, comprising: a base 1, the lower end face of which is provided with anti-slip texture to improve the stability of the device; two upright plates 2 are fixedly connected to the upper end face of the base 1; an adhesive supply component, an adhesive application component, and a lifting component are installed on the two upright plates 2; a rotating roller 3 is installed on the lifting component; the adhesive application component includes an adhesive application roller 4 and an adhesive leveling roller 5 rotatably connected between the two upright plates 2; there is a corresponding gap between the adhesive application roller 4 and the adhesive leveling roller 5; the adhesive application roller 4 has a bidirectional spiral groove with the groove depth gradually changing from the middle to both ends; a collecting plate 6 is fixedly connected between the two upright plates 2; a scraper is fixedly connected to the upper end face of the collecting plate 6; the scraper is in contact with... On the glue-spreading roller 5, a collection groove 7 is fixedly connected to the collection plate 6. The collection groove 7 passes through one of the vertical plates 2. The scraper scrapes the excess glue on the glue-spreading roller 5 onto the collection plate 6. Then the glue is discharged through the collection groove 7 on the collection plate 6. The user can collect the glue at the discharge end of the collection groove 7. A first rotating gear 8 and a second rotating gear 9 are rotatably connected to the side wall of the other vertical plate 2. The first rotating gear 8 and the second rotating gear 9 mesh with each other. The first rotating gear 8 is fixedly connected to the glue-spreading roller 4, and the second rotating gear 9 is fixedly connected to the glue-spreading roller 5. A first motor 10 is fixedly installed on the side wall of one of the vertical plates 2. The rotating end of the first motor 10 is fixedly connected to the glue-spreading roller 4.

[0021] The adhesive supply assembly includes a collection box 11 fixedly connected to the upper surfaces of two upright plates 2. A drain pipe is connected to the collection box 11, and a valve is installed on the drain pipe. A limit ring 12 is fixedly connected to the inner wall of the collection box 11. A mounting bracket 13 slides inside the collection box 11, and a filter screen 14 is fixedly installed on the inner wall of the mounting bracket 13. Two handles are fixedly connected to the upper surface of the mounting bracket 13, facilitating the user to remove the mounting bracket 13 from the collection box 11, thus improving the portability of the device. The mounting bracket 13 is mounted on the limit ring 12. A metering pump 15 is fixedly installed on one of the upright plates 2. The metering pump 15 is existing technology. When the metering pump 15 delivers adhesive, it relies on its fixed displacement characteristics and volumetric working principle to form a volume change in the sealed cavity through the periodic movement of moving parts. In the suction stage, the cavity expands to generate negative pressure, drawing the high-viscosity adhesive from the storage port. In the discharge stage, the cavity volume is compressed, applying pressure to the adhesive and pushing it through the discharge port for stable output. This will not be elaborated further here. The liquid extraction end of the metering pump 15 is connected to the collection box 11. A connecting pipe 16 is installed between the two vertical plates 2. The connecting pipe 16 is connected to the liquid outlet end of the metering pump 15. Multiple nozzles are installed on the connecting pipe 16. A first sprocket 17 is fixedly connected to the first rotating gear 8. A second sprocket is rotatably connected to the side wall of the collection box 11.

A rotating roller 3 is rotatably connected to the two lifting blocks 21. A second motor 22 is fixedly installed on the side wall of one of the lifting blocks 21. The rotating end of the second motor 22 is fixedly connected to the rotating roller 3. The cylinder 20 can drive the lifting block 21 to move, thereby realizing the adjustment of the distance between the coating roller 4 and the evenly coating roller 5, making the device suitable for coating gauze of different thicknesses and improving the practicality of the device.

[0023] In use, the device is placed at the designated processing location. The cylinder 20, with its movable lifting block 21, raises and lowers the rotating roller 3 to a suitable position. The fabric is then placed between the rotating roller 3 and the coating roller 4. The first motor 10 and the second motor 22 then begin operation, causing the rotating roller 3 and coating roller 4 to rotate. Simultaneously, the metering pump 15 draws the adhesive from the collection tank 11 to the connecting pipe 16. The adhesive is then discharged through the nozzle and applied to the coating roller 4. Subsequently, with the cooperation of the first rotating gear 8 and the second rotating gear 9... The rotating glue roller 5, with its bidirectional spiral groove and counter-rotating shape, evenly spreads the glue on the glue roller 4 radially, resulting in a uniform and controllable glue layer thickness. This solves the problems of glue overflow at the edges and insufficient glue in the center of the fabric. During the application process, the stirring rod 19 rotates under the drive of the first sprocket 17, the second sprocket, and the chain 18, preventing the glue from separating and settling. At the same time, the filter screen 14 isolates and collects impurities in the glue in the collection box 11, preventing impurities from clogging the connecting pipe 16 and the nozzle, thus ensuring the normal operation of the device.
