Scrape coating machine for edge banding

Abstract

The invention relates to the technical field of edge banding production equipment, in particular to a scrape coating machine for an edge banding. The scrape coating machine comprises a machine tool provided with an unwinding plate, an adhesive melting device, a scrape coating device, an edge banding turning device, a cooling channel and a winding plate, wherein the unwinding plate is located above the front side of the machine tool, the adhesive melting device is located on the rear side of the machine tool, the scrape coating device is located on the front side of the machine tool and connected with the adhesive melting device, the edge banding turning device is connected with an output end of the scrape coating device, the cooling channel is connected with an output end of the edge banding turning device, and the winding plate is located on one side of an outlet end of the cooling channel. The scrape coating machine for the edge banding is small in size, lower in production cost and little in occupied space during use; the glue spreading edge sealing machine is suitable for coating the back side of the edge banding with a hot melt adhesive, is particularly suitable for the edge banding with the width ranging from 16 mm to 65 mm and the thickness ranging from 0.4 mm to 3 mm, the coating quantity is 50 -250 g / m<2>, the production efficiency is high, the adhesive coating is uniform and stable, and the adhesive coating quality is good.

Description

technical field [0001] The invention relates to the technical field of edge banding strip production equipment, in particular to an edge banding strip coating machine. Background technique [0002] Edge banding is a material for protecting, decorating and beautifying the section of furniture panels. Its main function is to seal the section of the panel so as to prevent the panel from being damaged by the environment and unfavorable factors during use. Unique color and texture design and other decorations make the applied furniture panel products more textured and three-dimensional. For flat edge banding products, back coating treatment is an important process related to product quality. [0003] The prior art has disclosed a device for applying hot melt adhesive on the back of the edge band, which includes an unwinding device for releasing the edge band, and applies hot melt adhesive on the back side of the edge band to obtain a glued edge band. A melt glue coating device,...

AI Technical Summary

Problems solved by technology

There are the following four defects in the above-mentioned existing edge banding back coating device: one, each device is connected in sequence to form an assembly line type edge banding back coating hot melt adhesive device, this kind of assembly line type edge banding back coating The hot melt adhesive device occupies a very large area, and the production cost is high; second, this kind of edge banding back coating hot melt adhesive device can only apply glue to thinner edge banding, and the flexibility is poor; third, the glue coating method belongs to Roller coating, after the completion, an edge banding strip with a textured hot-melt adhesive is formed, and the contact area of ​​the edge banding strip is small when sealing and bonding the cross-section of the board, and the bonding effect is not good; 4. Melting glue device and coating The devices are all fixed installations and cannot be disassembled. When hot melt adhesive particles of different materials or colors need to be replaced, production needs to be stopped for replacement. The replacement process is cumbersome and time-consuming.
