Abstract

The invention relates to the field of hot melt devices, and discloses a hot melt device for producing thermoplastic polyurethane elastomers. The device comprises a bottom plate, wherein hydraulic rodsare arranged on two sides of the top outer wall of the bottom plate, and fixed blocks are arranged on the top outer walls of the hydraulic rods; a hot melt tank body is arranged on the outer walls ofthe fixed blocks, and feed boxes are arranged on the top outer wall of the hot melt tank body; insulation covers are connected to the top outer walls of the feed boxes by hinges; a feed pipe is arranged at the bottom inner wall of each feed box and the top inner wall of the hot melt tank body, and discharge plates are arranged on two sides of the bottom inner walls of the feed boxes. The device has the following advantages and effects: the feed boxes, a second motor and crushing rollers are arranged, after materials enter the feed boxes, the second motor is started, the materials are crushedby the crushing rollers, the surface area of the crushed materials is increased, the hot melting speed of the materials can be effectively improved, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of hot-melt devices, in particular to a hot-melt device for producing thermoplastic polyurethane elastomers. Background technique [0002] Thermoplastic polyurethane elastomer is also called thermoplastic polyurethane rubber. Thermoplastic polyurethane rubber is cross-linked by intermolecular hydrogen bonds or slightly cross-linked between macromolecular chains. As the temperature increases or decreases, these two cross-linked structures are reversible. [0003] After searching, the Chinese patent application number is 201821720598.1, which discloses a hot-melt device for the production of thermoplastic polyurethane elastomers, including a box body. The box body is a cylindrical barrel, and the inner wall of the box is provided with a heating plate. The inside of the box body is provided with a stirring device for convection of the material. The present invention improves the existing device and adds a stirr...
