Description

Technical Field

[0001] This utility model relates to the field of gluing technology in sandpaper production, and in particular to a gluing device for sandpaper production. Background Technology

[0002] The adhesives used in sandpaper production mainly include resin adhesives and sandpaper adhesives. Resin adhesives are typically used for coating the substrate, while sandpaper adhesives are used to enhance the adhesion between the abrasive grains and the substrate.

[0003] Existing sandpaper production requires a gluing device to apply adhesive during production. However, this process typically involves evenly spreading the adhesive across the sandpaper surface, resulting in excess adhesive spilling onto the outer edges of the sandpaper, leading to significant adhesive consumption and requiring manual intervention. To address these issues, we propose a new sandpaper production gluing device. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a gluing device for sandpaper production, which can solve the problem that existing sandpaper production requires the use of a gluing device to apply glue to the sandpaper. However, when applying glue to sandpaper, it is usually necessary to evenly apply the glue to the surface of the sandpaper, which may result in excess glue leaking onto the outside of the sandpaper, leading to a large amount of glue consumption and requiring manual handling.

[0006] To solve the above technical problems, this utility model provides a gluing device for sandpaper production, which adopts the following technical solution: it includes a processing table, a conveyor belt is provided inside the processing table, and residual liquid recovery components are provided on both the front and rear sides of the conveyor belt;

[0007] The residual liquid recovery assembly includes a collection box, a reciprocating screw, a slider, a baffle, an adhesive scraper, recovery chambers, a recovery pipe, and a pump. The collection box is fixedly installed on the top of the processing table, and a reciprocating screw is rotatably connected between the inner walls of the front and rear sides of the collection box. A slider is movably connected to the external thread of the reciprocating screw. A baffle is fixedly installed inside the collection box, and the slider is slidably disposed between the baffle and the inner side of the collection box. An adhesive scraper is fixedly installed on the side of the slider near the baffle, and the lower surface of the adhesive scraper is attached to the bottom of the inner side of the collection box. Two recovery chambers are sequentially opened from front to back on the bottom of the inner side of the collection box, and a recovery pipe is fixedly connected to the bottom of each of the two recovery chambers. A pump is fixedly installed on the bottom of the processing table, and the input end of the pump is fixedly connected to the recovery pipe.

[0008] Optionally, a support frame is fixedly installed on the top of the processing table, and an adhesive storage box is fixedly installed on the top of the support frame. Input pipes are fixedly installed on both sides of the adhesive storage box, and the top output ends of the two pumps are fixedly connected to the input pipes.

[0009] Optionally, an addition tube is fixedly installed on the top of the adhesive storage box, and a dispensing machine is fixedly installed at the bottom of the adhesive storage box. The dispensing machine is located at the bottom inside the support frame, and the dispensing end of the dispensing machine is directly facing the surface of the conveyor belt.

[0010] Optionally, a first fixed plate and a second fixed plate are symmetrically fixed on the top of the processing table. A first rotating shaft and a second rotating shaft are rotatably connected between the first fixed plate and the second fixed plate from front to back. The conveyor belt is movably disposed outside the first rotating shaft and the second rotating shaft. A drive motor is fixedly installed on the right side of the second fixed plate. The output end of the drive motor is fixedly connected to the right end of the second rotating shaft.

[0011] Optionally, the first rotating shaft extends to the outside of the first fixed plate and the second fixed plate respectively, and a first bevel gear is fixedly installed at both ends of the first rotating shaft. The front ends of the two reciprocating screws extend to the front side of the collection box, and a second bevel gear is fixedly installed at the front ends of the two reciprocating screws. The second bevel gear meshes with the adjacent first bevel gear.

[0012] Optionally, a connecting frame is fixedly installed between the tops of the two collection boxes, and a plurality of spreading plates are fixedly installed at the bottom of the connecting frame, with each spreading plate located directly above the conveyor belt.

[0013] In summary, this utility model has at least one of the following beneficial effects: 1. By setting up a residual liquid recovery component, when the adhesive coating on the sandpaper surface is spread evenly, the excess adhesive overflows into the collection box. By setting up a first rotating shaft, a first bevel gear, a reciprocating screw, and a second bevel gear, the reciprocating screws on both sides of the conveyor belt also rotate simultaneously. The rotation of the reciprocating screw drives the adhesive scraper on one side of the slider to push the adhesive inside the collection box into the recovery chamber. Then, the pump, recovery pipe, and input pipe add the adhesive inside the recovery chamber back into the adhesive storage box, completing the residual liquid recovery of the adhesive. This realizes the recycling of adhesive, reduces adhesive waste, and eliminates the need for manual cleaning by staff.

[0014] 2. By setting up a dispensing machine, the adhesive inside the adhesive storage box is applied to the sandpaper surface on the conveyor belt. As the conveyor belt moves, the droplets of adhesive are spread evenly by the spreading plate. By setting up multiple spreading plates, multiple droplets of adhesive can be spread evenly on the sandpaper surface. This not only ensures the adhesive is spread evenly, but also works in conjunction with the dispensing machine to complete the application with a small amount of adhesive, reducing adhesive waste.
