Screen, production method of screen and shredder provided with screen

Abstract

The invention relates to a screen, a production method of the screen and a shredder provided with the screen. The screen is matched with a toothed knife roll and comprises a screen plate, wherein screen holes are formed in the screen plate, the screen plate bends and extends in a first direction, and the section, perpendicular to the first direction, of the screen plate is waved so as to be meshed with the toothed knife roll. The section, perpendicular to the first direction, of the screen plate is waved and is meshed with the toothed knife roll, so that the knife roll is matched with the screen during operation, smaller materials shred by the knife roll can fall off via the screen holes, and materials with diameters larger than those of the screen holes can continuously move along with the knife roll to be further shred and then fall off via the screen holes. The waved screen plate has a smaller gap with the knife roll, so that the materials can smoothly enter the screen holes 40 and fall off quickly, material blockage is prevented, and the size of the screen holes is not required to be increased.

Description

technical field [0001] The invention relates to the field of environmental protection machinery, in particular to a screen, a manufacturing method thereof and a shredder equipped with the screen. Background technique [0002] A shredder is a machine used for finely crushed materials. It is generally used to process unprocessed raw materials or scraps to make them smaller in size. It can be used to shred plastic, rubber, tires, fibers, paper, wood, iron drums, Solid or hollow materials such as waste electrical appliances, waste cables, industrial scraps, domestic waste, etc., have a wide range of applications in various fields. After the materials in the shredder are crushed, they need to be screened through the screen. [0003] The screen holes provided on the screen are generally circular holes, prismatic holes, and cross-shaped holes. Due to the structural limitations of the screen, the shredded materials are scattered in an irregular manner. Due to the small screen hole...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to solve the problem that the screen of the shredder cannot ensure the smooth passage of materials through the screen holes at the same time and ensure a certain size requirement, and provide a screen that can ensure the smooth passage of materials and has a high discharge quality and its manufacture.
