Description

Technical Field

[0001] This utility model relates to the field of pulp molding technology, specifically to a pulp molding suction filter forming machine. Background Technology

[0002] The pulp molding suction filter molding machine is a piece of equipment used to produce molded pulp products. It primarily uses suction filtration technology to uniformly mold pulp raw materials. Its working principle involves using negative pressure suction to adsorb the pulp suspension onto the mold surface, and then removing excess water through a filtration process, ultimately forming the molded pulp product. This molding machine is suitable for producing various environmentally friendly packaging, disposable tableware, industrial pallets, and other pulp products. It boasts advantages such as high efficiency, energy saving, and environmental friendliness, and is widely used in the packaging, food, and consumer goods industries.

[0003] In the prior art, such as the Chinese patent with publication number CN221608486U entitled "A Pulp Molding Suction Filter Molding Machine," the disclosed technical solution describes a device that uses a first lifting device and a second lifting device to drive the entire fixed frame to rise or fall, or the pulp tank to rise or fall individually. Raising the entire fixed frame facilitates the removal of the wet preform by a robotic arm, while lowering the frame moves it away from the robotic arm to avoid collision. Raising the pulp tank allows the molding device to be immersed in the pulp for suction filtration molding, while lowering the tank allows the molding device to leave the pulp. This prevents collisions and mutual influence between components, improving work efficiency. However, during the wet paper preform molding process, uneven fiber distribution in the pulp entering the mold leads to uneven thickness on different surfaces of the wet paper preform during suction filtration molding, affecting the quality of the final product.

This causes the lower template 320 to vibrate while reciprocating, causing the pulp on the upper surface of the lower template 320 to flow back and forth, making the fiber distribution more uniform, and making the fiber adhesion on the forming filter screen 321 more uniform. This makes the thickness of each surface of the wet paper mold blank formed by suction filtration more uniform.

[0024] The second hydraulic telescopic rod 300 drives the lower template 320 to rise through the lifting frame 310 and move it out of the pulp. It then closes with the upper template 280 to squeeze and dewater. After dewatering, the first air pump 250 is started, and the wet paper mold blank is adsorbed through the first connecting pipe 260 to demold. After demolding, the motor 220 drives the T-block 240 to move the upper template 280 above the lifting plate 160 through the screw 230. The first hydraulic telescopic rod 170 drives the lifting plate 160 to move upward so that the wet paper mold blank falls on the lifting plate 160. Then, the first hydraulic telescopic rod 170 drives the lifting plate 160 to descend onto the support plate 150 for easy handling by the operator.
