Continuous pulp shaping machine and working method thereof

Abstract

The invention discloses a continuous pulp shaping machine, and belongs to the key technical field of cleaning production. The continuous pulp shaping machine comprises a hot pressing shaping machine table, a lower mold base, a hot pressing assembly, a transfer manipulator and a pulp molding forming machine; the hot pressing assembly comprises a first sliding block, a third air cylinder and an adsorption plate, the pulp molding forming machine comprises a pulp pool, a first driving motor, a rotating track, a set of upper pulp suction molds, a set of upper pulp suction mold driving assemblies, aset of lower pulp suction molds, a set of lower pulp suction mold driving assemblies, a forming mold, a forming mold driving assembly, a gantry, an extrusion forming table, an upper pulp suction moldfeeding assembly and a lower pulp suction mold feeding assembly. The continuous pulp shaping machine is reasonable in structural design, high in working efficiency and flexible to apply. A working method of the continuous pulp shaping machine has the advantages that the degree of automation in the working process is high, the production efficiency is improved, and the working method is suitable for industrial large-scale application.

Description

technical field [0001] The invention belongs to the key technical field of clean production, in particular to a continuous pulp shaping machine. The invention also relates to a working method of a continuous pulp shaping machine. Background technique [0002] Pulp molding is a three-dimensional papermaking technology, usually using waste newspapers, recycled cartons, paper tubes, pure wood pulp, etc. After adsorption on the net mold, a certain shape of wet pulp semi-finished product is formed, and then dried and hot-pressed to process the pulp molded product (such as a molded paper cup). [0003] Pulp molding equipment is to mold the wet pulp in the mold and then dehydrate and dry it to form a container product of the desired shape. There are currently two forms: one is to complete the pulp making in the net mold, vacuum adsorption, and preliminary removal After the moisture content, it enters the drying process for drying.

Problems solved by technology

[0003] Pulp molding equipment is to mold the wet pulp in the mold and then dehydrate and dry it to form a container product of the desired shape. There are currently two forms: one is to complete the pulp making in the net mold, vacuum adsorption, and preliminary removal After the moisture content, it enters the drying process for drying. The disadvantage is that the paper blank is easy to deform during the transfer process due to its high water content, and shrinks and deforms again during the drying process. Therefore, it must be dried again after drying. The product is heated, pressed, shaped, and trimmed, and the product cannot eliminate the texture of the paper-making net; the other is in-mold grouting and extrusion, and electric drying is once formed. Pressing and drying with a net, the disadvantage is that it is still unable to eliminate the texture of the product, and the mesh is easy to block, and it needs to be washed repeatedly with water, and the net mold is easy to be damaged

In addition, there are currently two commonly used methods for pulp forming and drying: one is to use steam, heat transfer oil, and microwaves as heat sources, and complete the drying in the drying tunnel. The disadvantage is that the product is easy to deform, and it needs hot pressing and shaping after drying; Pressurized drying has the disadvantages of high energy consumption, high cost, and the heating element is easily damaged

Therefore, for the current high-efficiency production rhythm, there is no efficient integrated pulp molding machine for production, which greatly reduces work efficiency
