Hot-pressing shaping machine for paper-pulp molding and working method thereof

Abstract

The invention discloses a hot-pressing shaping machine for paper-pulp molding and belongs to the field of key technologies of cleaning production. The hot-pressing shaping machine comprises a hot-pressing shaping machine platform, a lower mold seat, a hot-pressing component, a transferring manipulator and a forming machine for paper-pulp molding, wherein the hot-pressing component comprises a first sliding block, a third cylinder and an adsorbing plate; the hot-pressing shaping machine platform is internally provided with an electric heating module which is positioned under the lower mold seat; the first sliding block is arranged on a sliding rail of the forming machine for paper-pulp molding; the third cylinder is connected with the first sliding block; the adsorbing plate is arranged atthe extending end of the third cylinder and is internally provided with an electric heating module and a second electromagnet; and the adsorbing plate is opposite to the lower mold seat in the upsideand downside. The hot-pressing shaping machine disclosed by the invention has the beneficial effects of reasonable structure design, high working efficiency and flexibility in application. A working method of the hot-pressing shaping machine for paper-pulp molding has the beneficial effects of high automation degree in the working process, increased production efficiency and suitability for industrial large-scale application.

Description

technical field [0001] The invention belongs to the key technical field of clean production, and particularly relates to a pulp molding hot-pressing machine. The invention also relates to a working method of a pulp molding hot-pressing machine. Background technique [0002] Pulp molding is a three-dimensional papermaking technology. It usually uses waste newspapers, recycled cartons, paper tubes, pure wood pulp, etc. as raw materials. The wet blank pulp semi-finished product of a certain shape is shaped by adsorption on the mesh mold, and then the pulp molded product (such as a molded paper cup) is processed through a drying and hot-pressing shaping process. [0003] Pulp molding equipment is to form wet pulp in a mold and then dehydrate and dry it into a container product of the desired shape. There are currently two forms: one is to complete pulping in the mesh mold, vacuum adsorption, and preliminary removal. After the moisture, it enters the drying process for drying. ...

AI Technical Summary

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
