Pulp box and paper-form wet base forming equipment

Abstract

The invention provides a pulp box. The pulp box comprises a box body, a first pulp feeding device and a second pulp feeding device and is characterized in that the box body comprises a bottom wall anda lateral wall; the bottom wall is provided with a bottom plate, the bottom plate separates an upper cavity into an upper cavity body and a lower cavity body, at least one upwardly-extending verticalwall is arranged on the bottom plate, an overflow groove is formed between each vertical wall and the lateral wall, and the upper cavity body is communicated with the lower cavity body through the overflow grooves; the first pulp feeding device is arranged in the lower cavity body and communicates the lower cavity body and the upper cavity body; the second pulp feeding device is arranged on the lateral wall and communicates the overflow groove with an external pulp tank; the external pulp tank conveys pulp to the overflow grooves through the second pulp feeding device, the first pulp feedingdevice conveys the pulp of the lower cavity body to the upper cavity body, and the pulp of the upper cavity body flows back into the lower cavity body through the overflow grooves. The invention further provides paper-form wet base forming equipment using the pulp box. The pulp can uniformly flows in the box body of the pulp box. By the paper-form wet base forming equipment, large-batch productionof high-precision paper-form wet bases can be achieved.

Description

technical field [0001] The invention relates to the field of pulp molded product devices, in particular to a slurry box and a paper mold wet blank forming equipment. Background technique [0002] Pulp molding is a green and environmentally friendly product made of completely recyclable plant fiber pulp or waste paper as the basic material. It is the best substitute for foam plastic products in the fields of broken product liner packaging and so on. [0003] The paper mold wet blank production equipment on the market includes a frame, a slurry box, an upper mold mechanism and a lower mold mechanism arranged on the frame. The slurry box is arranged at the lower part of the frame, and the lower mold mechanism is arranged above the slurry box. The mechanism can enter or exit the slurry box to prepare the wet paper mold blank. The upper mold mechanism is arranged on the upper part of the frame corresponding to the lower mold mechanism, which is used to transfer the paper mold we...

AI Technical Summary

Problems solved by technology

A common slurry box includes a box body. When the lower mold mechanism enters or exits the slurry box, the liquid level in the box fluctuates, and the slurry does not flow directionally, resulting in uneven concentration of the slurry every time the slurry is sucked and formed, which seriously affects the paper mold. The quality of the wet billet affects subsequent processing

Later, the manufacturer of paper mold wet blank production equipment installed an overflow tank on the side of the slurry tank, so that when the liquid level in the tank fluctuated, the slurry exceeding the height of the edge of the tank overflowed into the overflow tank, thereby overcoming The uneven concentration of the slurry is caused by the non-directional flow of the slurry, but this kind of slurry box has the following defects: after the lower mold mechanism absorbs the slurry, part of the slurry will settle to the bottom of the slurry box, making it difficult to accurately control the slurry concentration in the slurry box , resulting in a low qualified rate of pulp molded products. At the same time, because part of the slurry flows into the overflow tank and is directly discharged out of the slurry tank, it leads to waste of resources
