Air floating type sheeting and crushing machine for powder coating

Abstract

The invention discloses an air floating type sheeting and crushing machine for powder coating. The air floating type sheeting and crushing machine comprises a sheeting part, a conveyer belt and a crushing part. The conveyer belt is unfolded through a driven roller and a driving roller which are arranged at the two ends of a rack. A longitudinal groove is formed in the position of the longitudinal center line under the upper belt. Carrier rollers are arranged on the two sides of the longitudinal groove. An upper opening of the longitudinal groove is flush with the upper edges of the carrier rollers and is attached to the lower face of the upper belt. An air pipe introduced through a side plate is arranged below the longitudinal groove and communicates with the longitudinal groove through at least one vertical pipe. Air holes are formed in the positions, within the width range of the longitudinal groove, of the longitudinal center line of the conveyer belt. Shaft rods at one ends of two crushing rollers are connected through third synchronous gears so that the crushing rollers can rotate at an equal speed. Long teeth and short teeth are axially arrayed on the surface of each crushing roller at intervals, and the long teeth and the short teeth are distributed in the circumferential direction. The radius of a circle where the outer edges of the long teeth are located is greater than the radius of a circle where the outer edges of the short teeth are located. The radiating efficiency is high, sheeted pieces cannot adhere to the conveyer belt under the action of an air cushion, and the machine is simple in structure, easy to implement and suitable for application and popularization.

Description

technical field [0001] The invention relates to a powder coating processing equipment, in particular to an air-floating tablet crushing machine for powder coating. 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, its manufacturing equipment has not made major technological progress, such as tablet crushers, materials are mixed, melted, extruded, and compressed, a...

Problems solved by technology

[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, its manufacturing equipment has not made major technological progress, such as tablet crushers, materials are mixed, melted, extruded, and compressed, and then crushed after being cooled and transported by the conveyor belt. Since the sheet after tableting has not been fully cured, it is easy to stick to the conveyor belt, and the contaminated conveyor belt is not easy to clean. This problem still needs to be solved to promote the development of the powder coating industry.
