AI Technical Summary

Technical Problem

In existing electric glue feeding mechanisms, single-sided power drive leads to uneven glue stick feeding, which is prone to deviation or jamming, affecting glue dispensing stability and hindering the miniaturization design of hot melt glue guns.

Method used

The system employs a worm gear reduction transmission system and an adjustment and switching mechanism. Through the combination of worm, worm wheel, reduction gear and feeding gear, it achieves stable and uniform feeding of rubber rods. The cooperation of eccentric wheel and helical gear ensures precise supply of lubricating oil and avoids lubricating oil waste.

Benefits of technology

It ensures stable and uniform glue stick feeding, prevents deviation or jamming, improves glue dispensing stability and hot melt glue gun working reliability, while reducing lubricant waste and adapting to portable use needs.

Abstract

This utility model relates to the field of hot melt glue guns and discloses a glue feeding mechanism for a hot melt glue gun. The hot melt glue gun includes a feeding lubrication mechanism and an adjustment switching mechanism on its inner wall. The feeding lubrication mechanism includes a worm gear, the left end of which is rotatably connected to the inner wall of the hot melt glue gun. A worm wheel is meshed with the outer wall of the worm gear. A rotating rod is fixedly connected to the inner wall of the worm wheel. A reduction gear is fixedly connected to the outer wall of the rotating rod. A second reduction gear is meshed with the outer wall of the first reduction gear. A second rotating rod is fixedly connected to the inner wall of the second reduction gear. In this utility model, by setting up a feeding lubrication mechanism, the feeding gears can ensure stable and uniform feeding of the glue stick. Simultaneously, the synchronous relative rotation of the two feeding gears can apply a balanced force from both sides of the glue stick, preventing the glue stick from shifting or jamming during feeding, thus improving the working reliability and glue dispensing stability of the hot melt glue gun.
