Example Embodiment

[0024] The purpose of the present invention is to provide a pre-press, the movable cross beam of the pre-press is provided with a synchronization device, so that the end of the movable cross beam of the pre-press can keep synchronous up and down movement, and avoid the tilt of the movable cross beam, Therefore, damage to each oil cylinder connected with the movable beam is avoided, and equipment maintenance costs are reduced.

[0025] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Please refer to Figure 1 to Figure 3 , figure 1 It is a schematic diagram of the front structure of the pre-press provided in the embodiment of the present invention, figure 2 It is a schematic diagram of the cooperation between the gear and the rack in the pre-press provided in the embodiment of the prese...

Abstract

The invention discloses a pre-pressing machine. The pre-pressing machine comprises a rack, a moving cross beam, lifting oil cylinders, a plurality of main oil cylinders, synchronizing shafts, gears and racks, wherein the synchronizing shafts are rotationally arranged on the moving cross beam and parallel with a plane of the moving cross beam, and axes of the synchronizing shafts are parallel with a connecting line of the plurality of main oil cylinders; the same gears are arranged at two ends of each synchronizing shaft; and the racks are fixedly arranged on the rack of the pre-pressing machine, correspond to the gears in a one-to-one manner and are meshed with the gears. When the moving cross beam moves up and down, the gears are meshed with the racks and drive the synchronizing shafts to rotate, and rotation angles of two ends of each synchronizing shaft are equal all the time, so that two ends of the moving cross beam move up and down synchronously all the time, the problem that the two ends of the moving cross beam are inclined due to inconsistency of motions of the main oil cylinders is effectively solved, all oil cylinders connected to the moving cross beam are effectively protected, and the equipment maintenance cost is effectively reduced.

Description

Technical field [0001] The invention relates to the technical field of pressure machinery, in particular to a pre-press. Background technique [0002] Pre-pressing machine is an auxiliary machine for the plywood production line. It is a mechanical equipment for preliminary bonding of the panels before gluing in order to shorten the hot pressing cycle and improve the quality of the board during the production process. It is mainly used for the glued panels. Perform a short-time cold pressing to make it preliminary shape, and then send it to a hot press for hot pressing and gluing. The pre-press has an important general purpose for improving the quality of plywood and is an indispensable important equipment in the plywood production line. [0003] The pre-compressor is generally composed of a frame, movable beams, main cylinders, hydraulic systems, and control devices. The bottom of the frame is provided with a fixed beam, which is used to place the plates to be pressed, and the top ...
