Longitudinal wave type tabletting and crushing machine for powder coatings

Abstract

The invention discloses a longitudinal wave type tabletting and crushing machine for powder coatings. The longitudinal wave type tabletting and crushing machine comprises a tabletting part, a crushing part and a conveying belt. Two primary compression rollers are hollow round rollers; the gap between the two primary compression rollers is 1.5 mm to 2.5 mm; the axes of the two primary compression rollers are in parallel; and shaft rods at the two ends of each primary compression roller are connected with a machine frame. Two secondary compression rollers are hollow wave surface rollers; the axes of the two secondary compression rollers are in parallel; and shaft rods at the two ends of each secondary compression roller are connected with the machine frame. Annular up-and-down wave crests and troughs are arranged on the surfaces of the wave surface rollers. The shaft rods at one ends of the secondary compression rollers are connected through a second synchronous gear and rotate at the same speed; the wave crests of one wave surface roller are aligned at the wave troughs of the other wave surface roller; and the gap between the wave crest face and the wave trough face which are opposite is 1 mm to 1.5 mm. Long teeth and short teeth which are distributed in the circumferential direction are arrayed on the surface of a crushing roller in the axial direction at intervals, and the radius of the circle where the edges of the long teeth are located is larger than the radius of the circle where the edges of the short teeth are located. Overturning can be conducted easily during powder grinding so that multidirectional grinding can be achieved, accumulation is not likely to happen, the efficiency is improved, the structure is simple, implementation is easy, and the longitudinal wave type tabletting and crushing machine is suitable for application and popularization.

Description

technical field [0001] The invention relates to a powder coating processing equipment, in particular to a powder coating longitudinal wave tablet crusher. Background technique [0002] my country is the manufacturing center of the world, and it needs to consume a large amount of coatings every year. Most of the existing coatings are prepared liquid types. The cost of transportation must be high in barrels. Restricted by factors, powder coatings have developed rapidly in recent years. It has the advantages of low bagging cost, small space occupied by storage and transportation, small proportion compared with unit dosage, no volume dilution and no climate influence, avoiding losses due to freezing, and further reducing Storage and transportation costs in winter, with the need for increased production of powder coatings, there is no major technological advancement in its manufacturing equipment, such as tablet crushers, which are used to make fragments and then further pulverized...
