Description

TECHNICAL FIELD

[0001] The utility model belongs to the polyethylene wax production technical field, and specifically relates to a powder making device for polyethylene wax production. BACKGROUND

[0002] Polyethylene wax, also known as high molecular wax, is referred to as polyethylene wax. It is widely used due to its excellent cold resistance, heat resistance, chemical resistance and wear resistance. In normal production, this part of wax can be directly added to polyolefin processing as an additive, which can increase the gloss and processing performance of the product. As a lubricant, it has stable chemical properties and good electrical properties. Polyethylene wax has good compatibility with polyethylene, polypropylene, polyvinyl acetate, ethylene-propylene rubber and butyl rubber. It can improve the flowability of polyethylene, polypropylene and ABS and the demolding property of polymethyl methacrylate and polycarbonate. Compared with other external lubricants, polyethylene wax has stronger internal lubrication.

[0003] The file with the application number CN202022866475.2 proposes a powder making machine for polyethylene wax powder production. By installing a uniform material mechanism and a feed inlet on the top of the tower body, granular polyethylene wax falls onto the filter screen of the uniform material mechanism. The translation drive drives the push plate to reciprocate above the filter screen, spreads the accumulated material, and makes the material pass through the filter screen quickly and more evenly to the crushing mechanism below, improving the crushing efficiency and crushing uniformity. The crushing rollers of the crushing mechanism are provided with a plurality of crushing teeth. When the crushing rollers rotate, the crushing teeth on the adjacent crushing rollers engage with each other and extrude the granular polyethylene wax, crushing the granular polyethylene wax into fine powder. Compared with vertical installation, the horizontal arrangement of the crushing rollers can more evenly crush the falling material.

[0004] However, the above-mentioned powder making machine increases the translation mechanism to uniformly discharge and crush, but when crushing is only carried out by the crushing roller, part of the material will be pressed through the gap between the teeth of the crushing roller and enter the subsequent material collecting box. This requires multiple repeated crushing and is prone to cause part of the material to stick, affecting use. Utility model content
