Description

Technical Field

[0001] The utility model relates to the technical field of plywood production, in particular to a plywood shaping cold pre-pressing machine. Background Art

[0002] Plywood is one of the three major types of man-made boards and can also be used as material for airplanes, ships, trains, cars, buildings and packaging boxes. Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesives. Usually, an odd number of veneers are used, and the fiber directions of adjacent veneers are glued perpendicular to each other. After the plywood is assembled, it is necessary to use a pre-pressing machine to pre-press the slabs first, so that the multi-layer plywood is pre-pressed into one piece.

[0003] In the prior art, Chinese patent publication number CN216831401U discloses a plywood pre-pressing machine, which relates to the technical field of plywood production, and includes a frame, a pre-pressing platform and a pre-pressing mechanism. The pre-pressing mechanism includes a hydraulic cylinder and a pre-pressing plate. The hydraulic cylinder is located at the top of the frame, and the piston rod of the hydraulic cylinder passes through the frame and is connected to the pre-pressing plate. The pre-pressing platform is provided with a conveying mechanism for horizontally conveying the sheet assembly, and the conveying mechanism extends to the outer sides of the two ends of the pre-pressing platform along the conveying direction; the frame is provided with an adjustment mechanism for adjusting the position of the sheet assembly on both sides of the pre-pressing platform, and the adjustment mechanism includes a pressing plate assembly arranged in the vertical direction and a telescopic cylinder fixed on the frame for pushing the pressing plate assembly to move; the pressing plate assembly includes a first pressing plate and a second pressing plate, and the first pressing plate and the second pressing plate are connected by a plurality of springs, and the first pressing plate is connected to the telescopic cylinder. The pre-pressing machine facilitates loading and unloading of the sheet and can avoid the sheet offset during the pre-pressing process.

[0004] However, when the utility model is actually used, during the processing, the surface of the plywood is prone to have a lot of wood chips and fragments. It is not convenient to clean the plywood before pre-pressing, so that the wood chips and the plywood are pre-pressed together, which affects the flatness of the plywood. The surface is prone to unevenness, affecting the appearance, so improvement is needed. Utility Model Content
