A kind of gluing device and working method for flannelette sandpaper produced by sandpaper

Abstract

The invention discloses a flannelette abrasive paper sizing device for abrasive paper production, and a working method thereof. The flannelette abrasive paper sizing device for abrasive paper production comprises a double-layer support. An upper support body is installed on the upper top surface of the double-layer support. A lower support body is installed on the lower top surface of the double-layer support. The upper support body is rotationally connected with a sizing roller. The lower support body is rotationally connected with a feeding roller. The sizing roller is located over the feeding roller. A plurality of glue scraper plates which are distributed in an array manner are inlaid in the circumferential surface of the sizing roller. A sizing wheel is inlaid between every two adjacent glue scraper blades. A portal frame located above the sizing wheel is arranged on the top surface of the double-layer support. An installation plate is connected to the bottom surface of a top plate of the portal frame. A plurality of glue injection nozzles which are distributed in an array manner are inlaid in the bottom surface of the installation plate. According to the flannelette abrasivepaper sizing device for abrasive paper production, the sizing roller can be partially replaced and repaired conveniently, recycling is achieved, and the production cost is reduced; and the surfaces ofmaterials can be coated glue more sufficiently and evenly, glue layers are more consistent in thickness, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of sandpaper production, in particular to a flannelette sandpaper gluing device for sandpaper production and a working method thereof. Background technique [0002] Flannel sandpaper is widely used in hardware, construction, furniture, automobiles and other fields. It is mainly used on electric and pneumatic polishing machines for surface polishing of metal, wood and other materials. Coating adhesive on the back of the velvet sandpaper to bond other materials to form a composite layer, so that the velvet sandpaper reaches a certain hardness, which is convenient for subsequent cutting and shaping of the velvet sandpaper; however, the existing velvet sandpaper gluing devices mostly use integral Glue roller, once the glue roller is partially worn, it will affect the balance of gluing, the glue roller must be replaced as a whole, and it cannot be reused through partial repair, resulting in waste of resources and...

[0002] Flannel sandpaper is widely used in hardware, construction, furniture, automobiles and other fields. It is mainly used on electric and pneumatic polishing machines for surface polishing of metal, wood and other materials. Coating adhesive on the back of the velvet sandpaper to bond other materials to form a composite layer, so that the velvet sandpaper reaches a certain hardness, which is convenient for subsequent cutting and shaping of the velvet sandpaper; however, the existing velvet sandpaper gluing devices mostly use integral Glue roller, once the glue roller is partially worn, it will affect the balance of gluing, the glue roller must be replaced as a whole, and it cannot be reused through partial repair, resulting in waste of resources and increase in cost; at the same time, the existing gluing device Most of the glue is set under the conveying line, and the glue roller is dipped to pick up the glue to glue the material passing through the top. This kind of gluing method is prone to uneven gluing and inconsistent thickness of the glue layer.
