Description

Glue gun mechanism Technical Field The utility model belongs to the technical field of tobacco production equipment, and particularly relates to a glue gun mechanism. Background The cigarette paper lap joint carrying the cut tobacco is glued at the glue gun, so that the cigarette paper lap joint is adhered to wrap the cut tobacco, and a long cigarette rod is formed. After the glue gun is used for a long time, glue dirt is deposited in the glue gun to block a glue path, so that glue supply is not smooth, and the normal operation of a cigarette making machine is affected. When maintaining the glue gun, need to disassemble and carry out inside cleanness, the glue gun that now uses comprises 3 sections, be glue gun anterior segment, glue gun middle section and glue gun rear segment respectively, supply rubber tube and trachea to be by clamp sleeve connection and seal of pressing plate extrusion cutting ferrule, need to break away from the rifle body with the rubber tube trachea and just can take off the glue gun when daily maintenance or clean glue gun, the cutting ferrule warp after the dismouting repeatedly can't guarantee the leakproofness and lead to leaking glue, glue supply is not enough, the cutting ferrule card is on the rifle body, also inconvenient when the pipeline breaks away from, waste time and energy, the leakproofness is unreliable, lead to leaking glue, it is necessary to improve it.
