Description

This application claims the priority of the Chinese patent application submitted to the China Patent Office on May 21, 2021, with the application number 202110558635.3, and the title of the invention is "A system and method for online crushing and processing of waste boards on a continuous hot-pressed line for wood-based panels". The entire contents are incorporated by reference in this application.

technical field

The invention belongs to the field of wood processing, and relates to waste board treatment technology generated in the production process of wood-based panels, in particular to an on-line crushing and processing system and method for waste boards in a continuous hot-pressing line of wood-based panels.

Background technique

Since the wood-based panel continuous hot press has a series of unique advantages such as continuous production, good product quality, high thickness accuracy of the board, low raw material consumption, many board specifications, high productivity, energy saving and heat saving, etc., it has been more and more popular in the production of wood-based panels. more and more widely used. At present, there are about 200 continuous hot-pressing production lines in China. The common 8-foot continuous hot press machine can produce continuous strips with a width of 2500mm and a thickness of 2-40mm. At the exit of the continuous hot press, both sides of the continuous strip are sawed and aligned to form a strip with a width of 2440mm. , and then cut into a large panel with a length of 7340mm through a cross-cut saw, and after passing the inspection of the panel quality device, it is sent to the flap cooling device by the large panel roller conveyor line, and after cooling, only sanding is performed. Specification sawing Cutting, a large panel can be cut into 6 sheets of 1220mm×2440mm specifications.

Although the wood-based panel continuous heat press is very advanced, it is inevitable to produce waste boards during the production process. The main reasons are: (1) The moisture content of the raw material is too high, or the temperature, pressure, and time are not well controlled during the hot pressing process. After hot pressing, after the raw edge plate is output from the press, bubbling will occur, making the plate in the thickness direction. Delamination occurs and becomes a waste board; (2) When the press is shut down and restarted for production, the first board that is output from the press after hot pressing cannot meet the requirements due to many indicators such as density and thickness. Rejection of waste boards; (3) The last section of boards before the press stops will also be rejected as waste boards; (4) The boards produced between different types of raw materials will also be rejected as waste boards; (5) After hot pressing, the Plates that fail to pass the density and thickness tests should also be rejected as waste plates.

For the unqualified waste boards, the maximum format size is 7340mm×2440mm, and the maximum weight of waste boards can reach about 315kg based on the conventional thickness of 22mm and density of 800kg/ ^m3 .

At present, the existing wood-based panel continuous hot-pressing line is not equipped with a waste board processing device. The waste boards detected by the board quality inspection device are manually removed from the large-scale board drum before entering the flap cooling device. Conveyor line, and then transported out of the hot press workshop for processing. Due to the large size and weight of the waste boards, it is labor-intensive to remove them manually. In addition, due to the large size of the waste boards, it is troublesome to carry them out of the workshop either manually or with the help of a shipping device. The wood-based panel continuous hot-pressing line has a high degree of automation, requiring very few operators, and only a few people monitor it in the control room. When waste boards are generated, additional personnel are required to handle them, resulting in labor waste, or temporary deployment of personnel from outside the hot-pressing workshop to remove them, causing inconvenience in management. This waste board processing method is extremely inconsistent with the automation degree of the wood-based panel continuous hot-pressing line.
