Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, and particularly relates to a drying device for the production of pulp molding products. Background Technique

[0002] Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material and shapes paper products of a certain shape on a molding machine with special molds. It has four major advantages: the raw material is waste paper, including board paper, waste carton paper, waste white edge paper, etc., with a wide source; its production process is completed by processes such as pulping, adsorption molding, and drying and shaping, which is harmless to the environment; it can be recycled and reused; its volume is smaller than that of foamed plastics, can be overlapped, and is convenient for transportation. Pulp molding, in addition to being used as lunch boxes and tableware, is more used for industrial buffer packaging and has developed very rapidly.

[0003] In the prior art, drying treatment is often required in the production process of pulp molding. In the common drying process of pulp molding, a large number of moldings are often stacked and placed for drying at the same time. The surfaces of the moldings mostly have depressions and protrusions of different degrees, and it is easy to form four corners that are damp and difficult to dry, resulting in an unsatisfactory drying effect.

[0004] Based on this, this scheme proposes a drying device for the production of pulp molding products. Content of the Utility Model
