Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plate processing, especially to a plate production and processing pre-press. BACKGROUND

[0002] The pre-press in plate production and processing plays an important role. In the plate production process, such as the production of plywood, fiberboard, particle board, etc., the raw materials are often in a loose state. Taking plywood as an example, multiple veneers are glued and pressed. The veneers are not tightly attached to each other after gluing, and there are many air gaps. The pre-press can make these loose veneers or other plate raw materials preliminarily compact by applying a certain pressure, making the layers more tightly attached to each other and reducing internal voids, laying a good foundation for subsequent hot pressing and other processes, which helps to improve the final density uniformity of the plate. For plates that need to be stacked and glued in multiple layers, it is necessary to maintain the relative position stability between the layers after gluing to prevent misalignment and slippage.

[0003] However, the prior art, such as Chinese Patent No. CN220429351U, "Small Pre-Press for Plate Production and Processing", discloses a small plate pre-press for plate production and processing, which includes a base plate, the outer wall of the base plate is provided with a base, the inner wall of the base is provided with a hydraulic cylinder, one end of the hydraulic cylinder is provided with a table assembly, the outer wall of the table assembly is provided with an upper support, the outer wall of the upper support is provided with a pre-press assembly, and the outer wall of the table assembly is provided with a side support. The pre-press assembly includes a slide seat provided on the inner wall of the upper support, two spring barrels are provided at the bottom of the slide seat, and rollers are provided at the bottom of the spring barrels. The plate pre-press, through the setting of the pre-press assembly, selects appropriate spring force according to needs, and in use, through the setting of the spring barrels, the rollers and the plate have good adhesion pressure, and the pressure is moderate.

[0004] However, this device does not have a clamping and centering structure, and cannot moderately clamp the plate from both sides or all around to accurately fix it at the center position or the predetermined accurate position of the pre-press working platform. It cannot ensure that the position of the plate during each pressing is standard and consistent, and manual centering and alignment are required, increasing labor costs. The device does not have an automatic push-out structure, and the pressed plate needs to be manually or with the help of other external equipment to be taken out from the pre-press. This process is time-consuming, reduces production efficiency, increases the possibility of safety accidents caused by human operation errors or equipment failures, and cannot create a safer atmosphere for the production environment. UTILITY MODEL CONTENTS

[0005] The purpose of this invention is to address the problems in the existing technology where the sheet metal cannot be properly clamped from both sides or around the edges to accurately fix it in the center or a predetermined position on the pre-pressing machine's working platform.
