Description

Technical Field

[0001] The utility model relates to the field of hot pressing devices, in particular to a hot grinding and hot pressing device used for producing artificial fiberboards. Background Art

[0002] Wood fiberboard is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into veneers, and then gluing them with adhesives. Usually, an odd number of veneers are used, and the fibers of adjacent veneers are glued perpendicular to each other. In the production of wood fiberboard, the hot press is one of the main equipment in the production process of wood fiberboard. It is used to hot press and glue the board blanks after the glue is applied.

[0003] After searching, a medium density fiberboard hot pressing forming device with the publication number CN202122558418.2 is specifically disclosed, including a bottom plate, support plates are provided on both sides of the top surface of the bottom plate, and a cross plate is provided on the top surface of the support plate, and hydraulic cylinders are installed on both sides of the top surface of the cross plate. In the utility model, the push plate is driven by the hydraulic cylinder to move, so that the fixed plate on the bottom surface of the push plate moves, and the hot pressing plate on the bottom surface of the fixed plate moves at the same time. When the hot pressing plate extends into the mold groove on the hot pressing mold, the fiberboard can be processed. The use of the limit rod, spring, buffer block and the buffer grooves on both sides of the top surface of the hot pressing mold can effectively play a buffering and shock absorbing role in the processing process, slow down the vibration generated in the processing process, reduce the adverse effects of large vibration on the processing process, and improve the stability in the processing process, which is beneficial to improve the production quality of the fiberboard.

[0004] Most hot presses use electric heating wires to heat the hot press plate and then hot press the fiberboard. However, in the existing technology, the hot press plate on the fiberboard hot press device does not have the function of edge grinding during the hot pressing process, which increases the labor intensity of workers and the labor cost of the enterprise production, which is not conducive to improving production efficiency. The hot press plate does not have a buffering function during the hot pressing process, which makes it easy for the hot press plate to cause impact during the hot pressing process. After a long time, the consumption of the hot press plate will be accelerated, thereby causing damage to the hot press plate and reducing the service life of the hot press plate.

[0005] Therefore, it is necessary to invent a hot grinding and hot pressing device for producing artificial fiberboard to solve the above problems. Utility Model Content
