Description

Synchronous feeding device of multilayer press

Technical Field

The application relates to the technical field of plate processing equipment, in particular to a synchronous feeding device of a multilayer press.

Background

In the processing technology of the plate, in order to improve the processing efficiency of the plate, a multi-layer press is designed to carry out hot pressing on raw materials to form the plate. However, in the use of the multi-layer press, the traditional feeding manner is that an operator loads the plate raw materials to be hot-pressed on the hot press plate layer by layer, the contact time between the plate raw material loaded first and the plate raw material loaded last is a certain time difference with the hot press plate, which may be 30 seconds, 1 minute, 2 minutes or even longer, and the thermosetting time of the adhesive in the plate raw materials on each layer of hot press plate is different, which causes the hot-pressing process of the plate raw materials on each layer of hot press plate to be different, and further causes the plate quality produced on each layer of hot press plate to be different. Therefore, a synchronous feeding device is needed to synchronously feed the raw materials to each layer of hot pressing plates of the press so as to avoid the problem that the quality of the plate is affected due to different contact time between each pressing plate and the raw materials.

The Chinese patent with the application number of 201820926342.X provides a bamboo chip hot press which is provided with a synchronous feeding device, wherein the synchronous feeding device comprises a fixed frame, a material rack for placing plates and a driving assembly for driving the plates to enter a pressing station; the material rack comprises a plurality of U-shaped rods for supporting the plates and a plurality of first locking bolts, a placing station for placing the plates is formed between every two adjacent U-shaped rods, and the height of the placing station is consistent with that of the pressing station; the driving assembly comprises a hydraulic telescopic rod, a third vertical rod welded at one end of the hydraulic telescopic rod, a plurality of pushing pieces used for pushing the plates into the pressing station and a hydraulic pump used for driving the hydraulic telescopic rod to stretch. The technical advantage lies in that the driving assembly is adopted to push the raw materials on the material rack, so that the synchronous feeding of the raw materials is realized, and the problem of different contact time between each pressing plate and the raw materials is avoided. However, the decorative paper, the wear-resistant paper and the like used in the plate raw materials are coiled materials, and each layer of raw materials in the plate raw materials are stacked without fixation, so that when the plate raw materials are pushed by the driving assembly in the synchronous feeding device, the stacked plate raw materials are prone to scattering. Once scattered plate raw materials are hot-pressed by the hot-pressing plate, the obtained product is different from the expected product, so that the production quality of the multi-layer press is reduced.
