[0002] A glue gun is a device used to spray or inject glue onto the surface of an object under pressure. It is usually installed at the output end of the coating system for operators to use.
[0003] Due to the differences in seasons and regions, the temperature and viscosity of the glue have a great impact on the delivery of the glue, especially in the glue coating system with a long delivery pipeline or a complex connection structure. The glue often solidifies in the pipeline due to temperature changes during transportation, causing the pipeline to be blocked, thus affecting the normal operation of the glue coating system. In the prior art, operators often set a heating component outside the delivery pipeline, and heat the pipeline through the heating component to achieve heating and heat preservation treatment of the glue in the pipeline. However, the glue remaining in the cavity of the glue gun will still cause the glue to block the glue gun when the temperature changes.
[0004] Therefore, in order to solve the above problems and avoid blockage of the glue channel in the glue gun due to temperature changes of the glue, it is necessary to improve the existing glue gun structure so that the glue gun can heat the glue in the glue channel, thereby achieving temperature control of the glue in the gun.
