Cleaning device for back face of breathable net belt of artificial board preforming press

Abstract

The invention belongs to the technical field of artificial board producing machinery and discloses a cleaning device for the back face of a breathable net belt of an artificial board preforming press. The cleaning device comprises a hair brush, a roller, a protective cover, a poking piece, a wind sucking port and a support; the hair brush is arranged on the outer face of the roller; left and right ends of the roller are respectively fixed on the support; left and right ends of the protective cover are fixed on the support and wrap the hair brush and the roller; left and right ends of the poking piece are fixed on the support and are arranged in the middle of the wind sucking port; the wind sucking port is arranged below the protective cover and is in the vertical direction, and a wind gap is downward. According to the cleaning device for the back face of the breathable net belt of the artificial board preforming press, removed fibers can be prevented from returning to the face of the breathable net belt, the hair brush can be cleaned effectively due to the existence of the poking piece, the product quality can be improved, the waste board rate can be reduced and the environment pollution in a workshop can be reduced.

Description

technical field [0001] The invention belongs to the technical field of wood-based panel production machinery, and relates to a device for cleaning a breathable mesh belt, in particular to a device for cleaning the reverse side of a breathable belt of a wood-based panel pre-pressing machine. Background technique [0002] The medium and high-density fiberboard of wood-based panels is made of raw materials that are ground into fibers and then pre-pressed and hot-pressed into fiberboards. The pre-pressing machine is the main equipment. Its important function is to initially compact the fluffy slab fibers after paving to reduce the fiberboard. Increase the thickness of the slab, improve the internal strength of the slab, and discharge the gas in it, and prepare for the slab transportation and hot pressing in the subsequent process. The breathable mesh belt is an important part of the pre-pressing machine, and it is mostly made of non-metallic materials such as nylon or polyuretha...

AI Technical Summary

Problems solved by technology

Authorized notification number CN202377236U discloses an online cleaning device that does not need to be shut down. It blows compressed air to the mesh belt, blows off the fibers on the breathable mesh belt, and immediately sucks the fibers away through the dust removal cover, but cannot clean the breathable mesh belt. Fiber impurities adsorbed on the reverse side (that is, the non-working side)

[0004] Due to the fact that the reverse side of the air mesh belt (that is, the non-working surface) will gradually accumulate raw material fiber impurities during the pre-compression and exhaust process, which will affect the exhaust, and the surface of the pre-paved slab will be exhausted from the middle to both sides. Seriously, because the gas cannot be removed, the gas left in the fiber will cause the slab to crack in the subsequent process
