Description

Technical Field

[0001] The utility model belongs to the technical field of paper-plastic processing, and in particular relates to a paper product forming hot-pressing and shaping machine. Background Art

[0002] Paper products refer to the production activities of using paper and paperboard as raw materials and further processing them into paper products. Paper product packaging has a wide range of uses, and the use of various types of paper packaging is widespread in all aspects of human life and production. Thermoforming machine is a type of forming machine, suitable for rubber, paper products, plastics and other industries. Put the paper raw material in the mold, sandwich it between the upper and lower hot plate molds, and apply pressure under the intelligent constant temperature of the electric heating plate to shape the raw material.

[0003] Before the hot pressing process, the paper product forming hot pressing and shaping machine of the prior art needs to screen out the broken paper fibers from the pulp pool, perform preliminary grouting and shaping, form a paper embryo, and then place the paper embryo on the mold of the hot pressing and shaping machine for hot pressing. Since the paper embryo is only initially formed and contains a certain amount of moisture and debris fibers, the debris fibers often fall and adhere to the surface of the mold before being placed in the hot pressing mold, resulting in uneven defects in the paper plastic product after hot pressing. When there are too many debris fibers, they need to be manually removed, which is more troublesome. Utility Model Content
