Forming mechanism of paper pulp molding equipment

Abstract

The invention relates to a forming mechanism of paper pulp molding equipment. The forming mechanismcomprises a machine frame, wherein the machine frame is connected with a paper pulp tank; the machineframe is positioned above the paper pulp tank and is connected with an upper die; the interior of the paper pulp tank is divided into an inner cavity and an outer cavity through a partition plate. The inner cavity is connected with a slurry inlet pipe; the outer cavity is connected with an overflow pipe; the partition plate comprises a vertical section; the lower end of the vertical section is connected with a lower inclined section which is inclined downwards; the lower inclined section inclines towards the center of the paper pulp tank; the machine frame is located on the lower side of theinner cavity of the paper pulp tank and connected with a lifting driving part; the driving end of the lifting driving part extends into the inner cavity of the paper pulp tank and is connected with aforming lower die; the lower side of theforming lower die is provided with a lower inclined surface mathed with the lower incline section of the partition plate; the lower side of the forming lower die is connected with a pulp suction pipe; the pulp suction pipe passes through the paper pulp tank and extend to the lower side of the paper pulp tank. According to the forming mechanism of the paper pulp molding equipment, paper pulp concentration is uniform and sufficient, and nopulp accumulation and overflow splashing is caused.

Description

technical field [0001] The invention relates to a sealing mechanism, in particular to a molding mechanism of pulp molding equipment. Background technique [0002] Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material, and molds a certain shape of paper products with a special mold on the molding machine. During the molding process, the lower mold needs to be placed in the pulp in the pulp tank The lower reciprocating movement is used for pulp suction. After the pulp suction is completed, part of the water is discharged through the pulp suction pipe, so that the pulp stays on the lower forming die. The lower forming die rises and then cooperates with the upper die to shape. During the process, the pulp water in the pulp tank must overflow to the outer cavity before being discharged. The inner cavity of the pulp tank of traditional pulp molding equipment is generally square, and there are dead corners in the inner cavity. During the re...

After the pulp suction is completed, part of the water is discharged through the pulp suction pipe, so that the pulp stays on the lower forming die. The lower forming die rises and then cooperates with the upper die to shape. During the process, the pulp water in the pulp tank must overflow to the outer cavity before being discharged. The inner cavity of the pulp tank of traditional pulp molding equipment is generally square, and there are dead corners in the inner cavity. During the reciprocating movement of the upper and lower molds , will cause uneven pulp water concentration, insufficient pulp volume, sedimentation, overflow and splashing, etc.
