Special glue melting device for high-viscosity and high-softening-point hot melt glue

Abstract

The invention provides a special glue melting device for high-viscosity and high-softening-point hot melt glue. The special glue melting device comprises a glue melting furnace body and a heating system; the heating system is arranged in the glue melting furnace body; the glue melting furnace body is sequentially provided with an upper-section glue melting area, a middle-section glue homogenizingarea and a lower-section glue storage area from top to bottom; the upper-section glue melting area is provided with a melting cutter assembly; a transverse flow guiding plate assembly is arranged in the middle-section glue homogenizing area; and the lower-section glue storage area is provided with a shunting cutter assembly and a vertical multi-wing flow guiding assembly. The glue melting device is sequentially provided with the upper-section glue melting area, the middle-section glue homogenizing area and the lower-section glue storage area from top to bottom; a material block enters the upper-section glue melting area from a glue inlet, is sheared by the melting cutter assembly and enters the middle-section glue homogenizing area; the transverse flow guiding plate assembly in the middle-section glue homogenizing area realizes static stirring of the melt glue so that the melt glue is uniform; and the melt glue enters the lower-section glue storage area to be stored. According to the glue melting device, the glue melting amount can reach 0.75-1.5 kg / min under the control of glue melting heating temperature of 180 DEG C to 235 DEG C.

Description

technical field [0001] The invention relates to the technical field of hot-melt adhesive production equipment, in particular to a special-purpose melting device for hot-melt adhesive with high viscosity and high softening point. Background technique [0002] In the new era of rapid high-tech development, my country's auto industry has entered a technological leap powered by new energy batteries, big data, and artificial intelligence, and a new era of driverless driving is coming soon. How to ensure the safety of automobile tires in motion must be promoted to an important agenda. [0003] At present, at home and abroad, the safety of automobile tires in driving is basically adopted: implanting a kind of anti-puncture and anti-leakage material on the inner bottom surface of the tire. When the tires of a moving car are pierced by foreign objects, there is no air leakage or slight air leakage, so as to ensure that the car can still continue to drive. There are generally three ...

Problems solved by technology

As a result, the speed of the melt glue cannot keep up with the demand for the glue output speed, so when producing and processing tires, it is necessary to increase the temperature of the melt glue (about 240°C to 260°C), and extend the heating time (3 to 5 hours), so as to ensure the processing of tires When the glue output is satisfied, the hot melt colloid will be degraded and deteriorated, carbon deposits and coking, and the viscosity will be uneven after long-term heating at high temperature, which will seriously affect the quality of the colloid. The tires cannot meet the quality requirements of not leaking, and there are often disadvantages that cannot meet the continuous processing

In particular, most of the melting glue equipment currently on the market has a melting glue volume of 20kg / 3h, which is low in efficiency, and how to increase the melting glue volume has always been the industry's long-standing demand
