Description

Liquid glue conveying device

The present invention provides a liquid glue conveying device, especially a conveying device in which air and liquid glue do not come into contact with liquid glue, and at the same time, the liquid glue can obtain sufficient pressure by manipulating the pressure of the container.

Press, modern people pay great attention to environmental protection and human health. Therefore, for the processing of raw materials or finished products, most of the processing options that can ensure a clean environment and human health are used as the processing options, and they are familiar with the adhesion or For the fitting of shoe materials, liquid glue is mostly applied directly to the workpiece to be processed. In order to facilitate the bonding of different materials and obtain better quality of the finished product after bonding or bonding, the traditional manufacturing process uses high pressure The procedure for operating the sealed barrel, but the replacement of the rehydration glue is carried out by dumping at the work site. This is prone to accidentally polluting the site when dumping, and because the liquid glue inevitably contains volatile gases, This procedure inevitably has a certain opening and closing procedure, as well as the operator's operating knowledge, and there is considerable electrical operation at the scene, which will inevitably be dangerous when the operator is slightly careless.

Furthermore, the traditional high-pressure barrel air compressor directly pressurizes the high-pressure water and gas In this way, it is prone to contamination, which will directly contaminate the surface of the object to be processed.
