Transverse wave type tabletting crushing machine for powder coating

Abstract

The invention discloses a transverse wave type tabletting crushing machine for powder coating. The transverse wave type tabletting crushing machine comprises a tabletting part, a crushing part and a conveying belt. First-stage compression rollers are two hollow circular rollers, wherein the dimension of a gap between the first-stage compression rollers is 1.5-2.5 millimeters, the axes of the first-stage compression rollers are parallel, and shaft rods at the two ends of the first-stage compression rollers are connected with a machine frame. Second-stage compression rollers are two hollow wave-surface rollers, wherein the axes of the second-stage compression rollers are parallel, and shaft rods at the two ends of the second-stage compression rollers are connected with the machine frame. Undulant wave crests and wave troughs which are parallel to the axes of the wave-surface rollers are arranged on the surfaces of the wave-surface rollers. The peak of one wave crest of one wave-surface roller and the low point of one wave trough of the other wave-surface roller are both located on a connecting line between the axes of the two wave-surface rollers, and the dimension of a gap between the peak and the low point is 1-1.5 millimeters at the moment. Long teeth and short teeth which are distributed in the circumferential direction are arranged on the surfaces of crushing rollers in a spaced and arrayed mode in the axial direction. The radius of the circle where the periphery of each long tooth is located is larger than that of the circle where the periphery of each short tooth is located. The transverse wave type tabletting crushing machine can be rotated easily during powder grinding, multidirectional grinding is achieved, sedimentation is unlikely to occur, the efficiency is improved, the structure is simple, implementation is easy, and the transverse wave type tabletting 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 transverse wave tablet crushing machine. 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 pul...

[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 increase in 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. However, the existing tablet crushing mechanism The fragments produced are all flat, and the deposition efficiency is low during powder grinding, and the larger fragments appear uneven when crushed. These problems still need to be solved to promote the development of the powder coating industry.
