Description

Technical Field

[0001] The utility model relates to the technical field of plate pressing machine equipment, in particular to a pressure maintaining device for a one-step forming plate pressing machine. Background Art

[0002] Presses are used to press furniture panels, wooden doors, various boards, and other items together. They also flatten and shape items, creating a stronger, tighter bond. They provide strong pressure without backlash. Presses can be broadly categorized as screw-type or hydraulic-type. Hydraulic cold presses generally offer superior performance. Screw-type presses are noisy and have slower lifting speeds than hydraulic presses. Hydraulic presses are quieter and offer faster lifting speeds.

[0003] In logistics transportation, we often encounter the transportation of clothing and textiles. After these textiles and clothing are bagged, there is a lot of gas inside, which takes up a lot of space. In addition, the existing vacuum method cannot maintain the shape of the object while removing the air. The traditional one-time forming press often requires a long time of pressing to ensure the tightness of the object. The existing hydraulic or screw press wastes a lot of energy when pressing for a long time due to factors such as the stress of the object and the hydraulic state, and cannot effectively maintain the same height for long-term extrusion. Therefore, a pressure maintaining device for a one-time forming press is proposed to solve the above problems. Utility Model Content
