specific Embodiment approach

[0024] As a specific embodiment of the present invention, the lower surface of the support plate 2 is symmetrically provided with a plurality of transition hooks 22, and below each transition hook 22 is a No. 1 hook 311, and each No. 1 hook 311 is fixed on On the side of the driving plate 31, below each No. 1 hook 311 is a No. 2 hook 321, and each No. 2 hook 321 is fixedly connected to the side of the driven plate 32. Each No. 2 hook 321 is bolted with a wire rope 23. One end, the wire rope The other end of 23 passes through the transitional hook 22, and is tethered on the No. 1 hook 311, and a push plate 231 is provided between adjacent steel wire ropes 23; The cooperation between the active plate 31 and the driven plate 32 strengthens the extrusion force on the plywood again; when the active plate 31 and the driven plate 32 move towards each other and approach at the same time, the No. 1 hook 311 on the active plate 31 pulls the wire rope 23 One end, then the other end of th...

Abstract

The invention belongs to the technical field of prepressing machines, and particularly relates to a prepressing machine for a plywood production line. The prepressing machine comprises a workbench, wherein a supporting plate and a prepressing unit are arranged on the workbench; the prepressing unit comprises a driving plate, a driven plate and lead screws; the upper plate surface of the driving plate is fixedly connected to the lower plate surface of a first plate through bolts, the inner sides of the four corners of the driving plate are connected to the four lead screws through first ball seats, and the four corners of the driving plate are in clearance fit with the outer rings of four supporting columns; one end of each lead screw is hinged to the supporting plate, and the other end ofeach lead screw is hinged to the workbench; the driven plate is arranged below the driving plate, the inner sides of the four corners of the driven plate are connected to the four lead screws throughsecond ball seats, the four corners of the driven plate are in clearance fit with the outer rings of the four supporting columns, and the rotating direction of balls in the second ball seats is opposite to the rotating direction of balls in the first ball seats; and through the cooperation among the supporting plate, an air cylinder and the prepressing unit, prepressing treatment of plywood is realized.

Description

technical field [0001] The invention belongs to the technical field of pre-pressing machines, in particular to a pre-pressing machine for a plywood production line. Background technique [0002] The pre-pressing machine is an auxiliary machine of the plywood production line. It is a mechanical device for preliminary bonding before gluing in order to shorten the hot-pressing cycle and improve the quality of the boards during the production process. The pre-pressing machine belongs to the pressure machine. The pre-pressing machine mainly cold-presses the veneer after gluing and assembling for a short time to make it preliminarily shaped, and then sends it to the hot-pressing machine for hot-pressing and gluing. It is an important equipment and an important link to improve the quality of plywood. The pre-pressing machine is generally composed of a frame, a fixed beam, a movable beam, a plate ejection device, an oil cylinder, a hydraulic system, and an electric control device. ...
