Description

Technical Field

[0001] The utility model relates to the technical field of wood powder material drying for molded pallets, in particular to a wood powder material drying device for producing high-strength molded pallets. Background Art

[0002] Molded pallets are made by drying some small wood scraps and some plant straw, adding glue and mixing, and then placing them in a mold for hot pressing, which can effectively reuse resources. The drying step is to control the moisture in the raw materials so that the finished pallets are not easy to deform or mold and rot, thereby extending the service life of the pallets.

[0003] When the existing pallet is used to produce wood powder materials for drying, only part of the raw materials can be moved forward slowly during the rotation of the scraper, resulting in large differences in the time it takes for the same batch of raw materials put into the insulation cylinder to be sent out of the insulation cylinder. Some of the raw materials may even remain in the insulation cylinder and be sent out together with the next batch of raw materials, resulting in large differences in the degree of drying of the raw materials. It is easy for some raw materials to be over-dried, which has a great impact on the quality of the final pallet. Utility Model Content
