Hot melt glue gun

Abstract

The invention discloses a hot melt glue gun. The hot melt glue gun comprises an outer shell; an inner rotating cylinder is rotationally connected into the outer shell; a plurality of glue pipes are movably mounted in the inner rotating cylinder; the front ends of the glue pipes are fixedly connected with a glue outlet conical head; a guide plate is formed on the inner wall of the inner rotating cylinder; a guide chute is formed in the guide plate; a one-way transmission shaft is rotationally connected into the outer shell; a driving plate is slidably connected into the outer shell; through grooves are formed in the inner walls of the glue pipes; a switching gear is connected in the outer shell; the lower portion of the outer shell is slidably connected with a switching plate; a linkage plate is formed at the upper end of the switching plate; and a heating sheet is arranged on the linkage plate. When the switching plate is located at the front limit position, the one-way transmission shaft rotates to enable a lowest glue stick to be fed forwards; and when the switching plate is located at the rear limit position, the one-way transmission shaft rotates to enable the inner rotating cylinder to rotate. According to the hot melt glue gun, the glue sticks can be heated for adhesion; the glue sticks with various colors can be mounted and accommodated; and the glue outlet conical head can move forwards and backwards, use is simple and convenient, and glue head pollution is prevented.

Description

technical field [0001] The invention belongs to the technical field of hot melt glue guns, in particular to hot melt glue guns. Background technique [0002] The Chinese patent document with the document number CN205887364U discloses a safety hot melt glue gun, which is suitable for melting a glue strip to output a melt glue liquid, and includes a gun housing, a melt glue propulsion unit, and a control assembly. The gun housing includes a glue filling port for filling the glue strip and a glue outlet for outputting the molten glue liquid. The glue pushing unit includes a trigger, a glue pushing mechanism controlled by the trigger, and a heater. The hot-melt glue gun is added with a timing device, and then the counting module is electrically connected with the warning device for control, so as to achieve the purpose of reducing structural redundancy, the control is more convenient, the integration is high, and the manufacturing cost can be effectively reduced. [0003] The ...
