  • Patent number: 11111054
    Abstract: An equal-fork pallet comprising a pallet body is provided. The pallet body is provided with a stand structure and a reinforcing structure, the reinforcing structure is a reinforcing rib embodied by a groove structure pressed on the surface of the pallet body, and the reinforcing rib comprises a connection type reinforcing rib and a semi-partition type reinforcing rib, the stand structure comprises a corner stand, an edge stand and a center stand, and neither end of the partition type reinforcing rib is connected to the stand. The equal-fork pallet has a reasonable structural design and strong pressure bearing capacity, with targeted layout and design of the reinforcing rib centralized position and stress concentration position such as stand. The pallet can overcome the problems of low local compressive strength and proneness to produce stress fracture and local cracking.

  • Patent number: 10773417
    Abstract: The present invention provides a method for processing a molded tray based on bamboo-wood mixed shavings, comprising: extracting, crushing, mixing, drying, separating by wind separation, heat balance treatment, mixing glue, paving and hot pressing, cooling and grinding, inspecting and warehousing. In the invention, the industrial trays are manufactured by mixed bamboo and wood materials. The bamboo materials do not include bamboo peels and other impurities. The use of bamboo materials can improve the quality of trays from raw materials and reduce the moisture content of the trays. In addition, the brittleness of bamboo materials can improve the hardness of trays. The combined bamboo materials and wood materials can increase the toughness of the product and reduce the cost; furthermore, each link in the production process is elaborately designed and adjusted in the invention. The industrial trays made by the processing method of the present invention have increased the weight supporting capacity by at least 1.
