Description

Technical Field

[0001] This utility model belongs to the technical field of tobacco production equipment, specifically relating to a glue gun mechanism. Background Technology

[0002] The cigarette paper laminations, carrying the tobacco, are glued at the glue gun to seal the paper and wrap the tobacco, forming a long cigarette strip. After prolonged use, glue residue accumulates inside the glue gun, clogging the glue path and causing insufficient glue supply, affecting the normal operation of the cigarette rolling machine. Maintenance of the glue gun requires disassembly and internal cleaning. The current glue gun consists of three sections: the front, middle, and rear sections. The glue supply tube and air tube are connected and sealed by a pressure plate squeezing a clamp. During routine maintenance or cleaning, the glue tube and air tube must be detached from the gun body to remove the glue gun. Repeated disassembly and reassembly deform the clamp, compromising the seal and causing glue leakage. Insufficient glue supply, clamping of the clamp onto the gun body, and inconvenient and laborious disconnection of the tubing all contribute to the problem. The unreliable seal leads to glue leakage, necessitating improvements. Utility Model Content

[0003] The purpose of this utility model is to provide a glue gun mechanism that enables quick and efficient assembly of the glue gun during cleaning and maintenance, improves efficiency, enhances sealing, prevents glue leakage, and ensures better functionality during use, thereby solving the problems existing in the background art.

[0013] Furthermore, sealing rings are installed at the connections of the glue storage chamber, air storage chamber, glue inlet channel, and air inlet channel at the front, middle, and rear sections of the glue gun.

[0014] Furthermore, a nozzle cover fixing boss is provided at the front end of the gun body, the first nozzle cover passes through the nozzle cover fixing boss, and the second nozzle cover passes through the notch of the nozzle cover fixing boss.

[0015] The beneficial effects of this utility model are:

[0016] In this technical solution, both the glue inlet tube and the air inlet tube are connected to the gun body via quick-connect couplings, making disassembly and assembly convenient.
