Problems solved by technology

The requirements for the bonding of fabrics and panels are relatively high. First, quantitative spraying is required. Too much glue is easy to see through, too little is easy to bulge, and secondly, there must be no unevenness or graininess on the surface. Uneven spraying will also cause streaks on the surface
Existing manual spray guns can also spray hot melt adhesive, but the amount of glue sprayed manually is not uniform, far from meeting our requirements, and it is time-consuming and laborious

Abstract

The invention discloses an automatic hot melt adhesive spraying device for screen cloth. The device comprises a conveyor belt, a hot melt adhesive machine, a nozzle group, a sensing device, a motor and a control box, wherein the hot melt adhesive machine communicates with the nozzle group through an adhesive pipe, the sensing device is arranged on the front side of the nozzle group, the nozzle group comprises a plurality of adhesive spraying groups, each adhesive spraying group comprises a spray gun, an air pipe, an electromagnetic valve and an air pressure control valve, a spray sheet is arranged in each spray gun, and a plurality of adhesive spraying holes are formed in each spray sheet. The hot melt adhesive can be quantitatively sprayed in a mist mode, mist spraying is more uniform, under the condition that it is guaranteed that the peel strength reaches the standard after the fabric and a plate are bonded, surface defects caused by adhesive penetration are avoided, and surface unevenness and granular sensation do not exist.

Description

technical field [0001] The invention relates to a device for making screens, in particular to a device for automatically spraying hot melt glue on screen cloth. Background technique [0002] At present, among office furniture products, screens are an indispensable requirement for customers. In most of the screen products, the table screen is composed of cloth panels, so panel cloth has become a necessary process. The bonding requirements of fabrics and boards are relatively high. Firstly, quantitative spraying is required. Too much glue is easy to see through, too little is easy to bulge, and secondly, there should be no surface unevenness, graininess, and uneven spraying will cause streaks on the surface. Existing manual spray guns can also spray hot melt adhesive, but the amount of glue sprayed manually is uneven, far from meeting our requirements, and it is time-consuming and laborious. Contents of the invention [0003] The technical problem to be solved by the prese...
