Device for supplying unmelted hot melt adhesive pieces

Abstract

The invention discloses a device for supplying unmelted hot melt adhesive pieces. The structure of the device comprises a power cord, a control panel, a feedwell, a preheating thermal insulation device, an air vent, a steel backing plate, a handle, an opening and closing door, a plug pin, and a feeding funnel, wherein the feeding funnel is embedded in the left end of the upper surface of the preheating thermal insulation device, the steel backing plate is welded with the lower end of the preheating thermal insulation device, the air vent is embedded in the upper end of the front side of the preheating thermal insulation device, the plug pin is welded with the left end of the opening and closing door, and the opening and closing door is hinged to the left end of the front side of the preheating thermal insulation device by the plug pin. The device for supplying unmelted hot melt adhesive pieces heats the hot melt adhesive pieces firstly through the preheating thermal insulation device when supplying the hot melt adhesive pieces to make the temperature of the hot melt adhesive pieces between the freezing point and the melting point, so that the hot melt adhesive pieces can quickly reach the melting point temperature when entering a melting box of a hot melt adhesive machine, thereby shortening the melting time of the hot melt adhesive pieces, improving the hot melt efficiency, ensuring the adhesive supply speed, and avoiding feeding interruption of the hot melt adhesive machine during the adhesive application.

Description

technical field [0001] The invention relates to a device for supplying unmelted hot-melt adhesive blocks, which belongs to the field of hot-melt adhesive blocks. Background technique [0002] Hot melt adhesive block is a kind of plastic adhesive. Its physical state changes with the change of temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless. It is an environmentally friendly chemical product. The current technical public equipment is in When supplying hot melt adhesive blocks, they are all untreated hot melt adhesive blocks under normal temperature conditions. At this time, the hot melt adhesive block is in a solidified state. Since it takes a long time for the hot melt adhesive block to rise from the freezing point temperature to the melting point temperature, the sol The efficiency is poor. When the hot melt adhesive is used quickly, the newly supplied hot melt adhesive block may not have time to mel...

AI Technical Summary

Problems solved by technology

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a device for supplying unmelted hot melt adhesive blocks, so as to solve the problem that the common equipment in the current technology is untreated under normal temperature conditions when supplying hot melt adhesive blocks. At this time, the hot melt adhesive block is in a solidified state. Since it takes a long time for the hot melt adhesive block to rise from the solidification point temperature to the melting point temperature, the sol efficiency is poor. When the hot melt adhesive is used quickly, the new supply The hot melt adhesive block may not have time to melt, resulting in the problem that the hot melt adhesive machine is cut off and shut down
