Ultra-strong shaving board production process

Abstract

The invention discloses an ultra-strong shaving board production process. The ultra-strong shaving board production process comprises the steps that (1), raw materials are chipped and conveyed to a swing screen, and metal components are excluded in the conveying process; (2), after the swing screen screens the raw materials, large wood chips are returned to a chipping machine for reprocessing, andthe qualified wood chips enter a wood chip stock bin and then enter a transition stock bin; (3), after the wood chips are flaked, the wood chips enter a wet shavings stock bin; (4), wet shavings arepreheated through a preheating pipeline and then enter a dryer for drying; (5), after drying, the shavings are subjected to dust removal through a cyclone dust collector, and then the shavings are separated through a material separation device and enter a three-layer shavings screen for screening; and (6), the three-layer shavings screen screens out large shavings, qualified core layer shavings and qualified skin layer shavings. By the adoption of the ultra-strong shaving board production process, the static bending strength and the inner gluing strength of shaving boards are greatly improved,the physical and mechanical properties are improved, the density is relatively reduced, raw materials are saved compared with similar products, the cost input is reduced, the energy consumption is reduced, and the function of saving glue is achieved.

Description

Technical field [0001] The invention relates to the field of particleboard, specifically a super-strength particleboard production process. Background technique [0002] The existing process is to use a chipper to chip small diameter wood or branch wood into small wood blocks with a thickness of about 5cm-8cm and a thickness of about 2cm-3cm. After passing through an intermediate conveyor and storage, they are transported to the shavings by a conveyor. In the machine, the wood chips are sliced ​​through the shavings to form machine-made shavings. The machine-made shavings are transported to the shavings screen by a conveyor for screening. The shavings screened out are divided into wood powder, qualified surface shavings, qualified core shavings, and oversized shavings material. The general process is to transport the wood flour to the wood flour silo for later incineration. The qualified surface shavings enter the surface silo, and the qualified core shavings enter the core silo...

AI Technical Summary

Problems solved by technology

[0003] Now domestic flaker equipment is basically relatively mature. If human factors are not considered, the ratio of the core layer shavings to the large shavings that are basically qualified in normal use of the equipment accounts for 1:15. All the large shavings that come out are ground into fine surface materials, which are all used on the surface of the particleboard. The main defect is that the large shavings are ground into relatively fine surface materials by a grinder, and the better core layer shaving raw materials are broken, resulting in relative process waste. ,The large shavings play a decisive role in the strength of the particleboard. On the one hand, it is a waste of resources to break the large shavings again, and on the other hand, the relative energy consumption of the large shavings is a waste of energy.
