Multi-station forming device for producing paper pulp seedling cup

Abstract

The invention relates to the technical field of squeezing fiber paper pulp or paper stock producing articles in models during a paper making period, in particular to a multi-station forming device for producing a paper pulp seedling cup. One or more multi-station forming machines are arranged at the inner periphery of a pulp chest; automatic flow control valves are arranged on the multi-station forming machines and are connected with a pulp conveying pipe; a metering pump is arranged on the pulp conveying pipe; a small-size stirrer is further arranged at the center of the pulp chest; an compressed air cylinder and a vacuum cylinder are respectively arranged on the left side and the right side of the small-size stirrer. According to the multi-station forming device disclosed by the invention, multiple stations existing in one chest can be realized; only one pulp conveying pipe is needed even if the number of the work stations is more; pipeline interfaces and pipeline elbows are reduced; the resistances of compressed air and vacuum in a pipeline are also reduced, and the leakage probability is reduced. No excessive pulp, overflow port, overflow groove, pulp reflowing pipe, pulp storage chest for reflowing pulp or pulp returning pump is needed. The investment of equipment is saved, the occupied space of a workshop is reduced, and the energy consumption of multiple circulating pipelines is reduced. The multi-station forming device has the advantages of high efficiency, small occupied area and low energy consumption.

Description

[technical field] [0001] The invention relates to the technical field of producing objects by pressing fiber pulp or paper material in a model in papermaking, in particular to a multi-station forming device for producing pulp seedling cups. [Background technique] [0002] Pulp seedling cups use recycled paper as raw material, add peat, plant fiber and other organic fertilizers, and add a certain amount of papermaking additives to make slurry. After vacuum adsorption and molding on the molding machine through the molding die, it can be dried or dried in the sun. The laminated packaging is a finished product, and there are special requirements for reheating and shaping. The pulp blind seedling cup can be degraded. After degradation, the cup body becomes fertilizer. The root of the seedlings in the cup can extend out of the cup body and be transplanted directly. There is no need to manually remove the seedlings from the cup like plastic seedling cups, which saves labor and does...
