Hot melt glue gun has precise opening and closing effect, a variety of nozzles, can meet the requirements of different production lines, unique filter design, easy to clean and other characteristics. General hot melt glue guns will not deform when used at 300℃ for a long time, and the joints are durable. Therefore, hot melt glue machines are widely used in electronics factories, food factories, packaging factories, etc. to bond products with hot melt adhesive strips. To make up for the shortcomings of automatic spray guns and meet the needs of mobile use, the gun body shell is made of imported materials, which can withstand 300℃ high temperature, ensuring that it will not deform under long-term high temperature use, and the gun body is light in weight, convenient and flexible to operate. The unique protective gear design prevents operators from accidentally getting scalded while working. At present, it is difficult to control the amount of glue discharged from the gun head of the hot melt glue dispensing gun on the market when it is working. There are many types of items that are glued with hot melt glue dispensing guns, and the sizes are different, and the required glue coating sizes are also different. The fixed glue outlet is not convenient for meeting the use of various items. Moreover, when using a hot melt glue dispensing gun, the gun body is often in a suspended state, and the hand has no force fulcrum, which is prone to shaking and tilting, resulting in deviation during the glue application, and then causing the glue coating position to be incorrect, which greatly reduces the adhesion effect.
