Description

Full-automatic medium/high density fiberboard processing production line

Technical Field

The utility model relates to a fibreboard manufacture equipment technical field especially relates to a in full-automatic/high density fibreboard processing lines.

Background

During the manufacturing process of the fiberboard, wood chip raw materials of different materials are needed to be proportioned, and therefore a feeding system capable of realizing flexible proportioning needs to be designed. Meanwhile, in the process of manufacturing the fiberboard, the wood chip raw material needs to be washed by a washing machine so as to remove impurities such as sandstone and the like in the wood chip raw material. During washing, the wood chip raw materials are conveyed into a case of the washing machine and float on the water surface in the case, and the wood chip raw materials on the water surface are repeatedly pressed into the water by continuously beating and pressing the washing roller, so that sundries such as gravels attached to the wood chip raw materials are separated, and the purpose of cleaning the wood chip raw materials is achieved.

In the existing washing machine, a certain gap is usually reserved between the left end face and the right end face of the washing roller and the inner wall faces of the left side and the right side corresponding to the case, and in the washing process, part of wood chip raw materials are easily clamped into the gap, so that the material clamping of the washing roller is stopped, the washing operation cannot be normal, and even the overload burning of a roller driving motor is caused. In order to solve the problem, the existing washing machine needs to be optimized and improved. In addition, in order to achieve the environmental protection goal in the production process, the cleaning water of the washing machine needs to be effectively recycled, so that the environmental protection performance and the energy saving performance of the production line are improved, and therefore a corresponding water recycling system needs to be designed for the washing machine.

Paving and forming are important processes for producing medium-density fiberboards, and forming equipment of the paving and forming machine is a paving machine. A strickle device is arranged at the slab outlet end of the spreading machine, and is particularly important as the last part of the spreading machine. The slab band with certain width and thickness in the forming chamber of the spreading machine is strickled off by the needle roller, so that the slab band reaches the thickness with flat upper surface and meeting the process requirements, and meanwhile, the needle roller scrapes redundant materials to the air suction opening and sucks the redundant materials back to the storage bin for recycling. The prior strickle device has no density adjusting function, can not adjust the density of the plate blank in a certain area of the formed plate blank in the width direction, and can not meet the order requirement of non-uniform density.

The pre-pressing forming process mainly has the function of preliminarily compacting the plate blank on the conveying belt through a pre-pressing machine to prepare for subsequent hot-pressing forming. The left side and the right side of the plate blank pre-pressed by the pre-press are usually uneven, and if the uneven rim charge directly enters the continuous hot press without treatment for hot pressing, irregular flashes are formed on the left side and the right side of the plate blank, so that raw materials are wasted, and the subsequent flash removing process is added.

In the production process of the environment-friendly medium density fiberboard, the molded plain board slabs need to be stacked, but due to different orders, the sizes of the plain board slabs produced in different batches are different. And the storage platform of the middle storage unit on the production line is a plurality of support ribs formed by civil engineering, so that in the process of stacking the plate blanks continuously produced on the production line into the plate stacks, the plate blanks need to be subjected to centering control, namely, the storage of the plate stacks needs to face the problem of centering placement, so that the center of the whole stack of plate blanks is located at the center of the storage platform, the position of the plate stacks is not accurate when the storage is avoided, the bottom support of the whole stack of plate blanks is not symmetrical, and the whole stack of plate blanks is deformed. The existing stacking platform is basically a stacking platform with a fixed standard and cannot meet the centering and stacking requirements of plates with different specifications.
