Brown mattress thermoforming method and device

Abstract

The invention discloses a hot press molding method of a palm mattress and a device. The method is characterized in that a plurality of layers of palm fiber sheets are hot-pressed simultaneously. The device comprises a base (1) and a top frame (2), wherein more than three layers of hot-press boards (5) used for hot-pressing and molding the palm fiber sheets are arranged between the base (1) and the top frame (2); a pressurization seat (8) which can pressurize the hot-press boards (5) is arranged above the hot-press boards (5), supported by the top frame (2) and controlled to move up and down through a lifting rail (3) and a hydraulic cylinder (6); at least one hot-pressing oil pipe which can convey hot oil into each layer of a hot-press board (5) is arranged on each layer of the hot-press board (5); and all the layers of the hot-press boards (5) are controlled to be separated or form press-fit through separation rods (4). According to the palm mattress and the device, batch production of the palm mattress can be realized, the production efficiency and the hot press molding quality of the palm mattress are improved, the hot pressing accuracy is higher, and the application range is wider.

Description

technical field [0001] The invention relates to a method and device for hot-pressing a brown mattress, and belongs to the technical field of mattress processing in bedding. Background technique [0002] At present, most of the production of brown mattresses is formed by hot-pressing brown silk sheets. The traditional production method is to heat-press the whole mattress, and press the brown silk sheets from bottom to top on the hot-pressing equipment. Because the mattress pressed out in this way is integral, only one mattress can be pressed at a time, and each mattress is produced independently according to the thickness, lacking the technology of standardized flow operation, resulting in very low production efficiency. And the process of pressing from bottom to top consumes more energy because of the gravity of the pressure seat to be overcome. Secondly, the dimensional accuracy of the existing brown mattress hot-pressing device is not very high, and there are pressure dev...

AI Technical Summary

Problems solved by technology

Since the mattress pressed out in this way is integral, only one mattress can be pressed at a time, and each mattress is produced independently according to its thickness, lacking the technology of standardized flow operation, resulting in very low production efficiency

Moreover, the process of pressing from bottom to top consumes more energy because of the need to overcome the gravity of the pressurized seat

Secondly, the dimensional accuracy of the existing brown mattress hot-pressing device is not very high, there are pressure deviation, overpressure, undervoltage and other situations during hot pressing, and the reject rate is high

Moreover, the hot-pressing plates of the existing brown mattress hot-pressing devices are usually flat plates, which cannot be pressed to produce some mattresses with special shapes, and the scope of application is narrow.

Therefore, existing brown mattress thermocompression forming method and device are still unsatisfactory
