[0001] The utility model relates to the technical field of furniture processing equipment, in particular to a cold pressing device for processing wood veneer materials. Background Art

[0002] The cold press machine for wood veneer materials is used to press furniture panels, wooden doors, and various boards. It can make the adhesion between the boards more firm and make the pressure of the boards strong without rebound.

[0003] Before cold pressing, glue will be applied between the boards. Therefore, during cold pressing, the glue will be squeezed by the wood board and overflow. Therefore, the wood board after cold pressing needs to be cleaned of the overflowing glue. However, during the cold pressing process, some of the overflowing glue will stick to the pressing plate and base of the cold press. Therefore, after the wood board is pressed, the glue attached to the pressing plate and base will bond to the top and bottom wood boards, which is not conducive to the separation of the board from the pressing plate or base, and requires manual separation. Utility Model Content

[0004] The utility model aims to provide a cold pressing device for processing wood veneer materials to solve the problems raised in the above-mentioned background technology.

[0023] Furthermore, multiple push-down mechanisms are symmetrically arranged inside the pressure plate 3. Both ends of the mounting plate 11 are fixedly connected to the inner wall of the groove by welding. The size of the movable hole corresponds to the size of the push-down rod 5. A threaded groove is provided at the top of the push-down rod 5. The position and number of the threaded grooves correspond to the position and number of the connecting bolts 9 respectively. A through hole is provided at the top of the connecting plate 6. The through hole has a smooth inner wall. The threads on the inner wall of the threaded groove are meshed with the threads on the outer wall of the connecting bolt 9.
