Description

A hot-melt glue gun with a temperature-controlled leak-proof device

technical field

The utility model relates to the technical field of hot-melt glue guns, in particular to a hot-melt glue gun with a temperature control leak-proof device.

Background technique

Hot melt glue gun is a decoration tool with precise breaking effect, a variety of nozzles, which can meet the requirements of different production lines, and unique filter design, which is conducive to cleaning and so on. Ordinary hot melt glue guns will not deform when used at a high temperature of 300°C for a long time, and the joints are durable. Therefore, hot melt adhesive machines are widely used in electronics factories, food factories, packaging factories, etc. to bond products with hot melt adhesive strips. The manual strip hot melt glue gun can make up for the shortcomings of the automatic spray gun and meet the needs of mobile use. The shell of the gun body is made of imported materials, which can withstand high temperatures of 300 ° C, ensuring no deformation under long-term high-temperature use, and The gun body is light in weight, convenient and flexible to operate.
