Description

Technical Field

[0002] Molded lunch boxes are made of sugarcane bagasse, straw, wheat straw, bamboo and other agricultural and forestry materials as the main raw materials. They are plant fiber molded tableware made through pulping, forming, molding, drying and other processes. They include molded paper cups, molded paper bowls, molded paper lunch boxes, molded paper plates, molded paper dishes, etc. During the production process, the paper film is usually processed and formed in a hot pressing mold.

[0003] According to the search, the Chinese patent with patent number CN115323829A discloses a water-resistant and oil-resistant pulp lunch box forming device and method, including a workbench, the upper surface of the workbench is fixedly connected to a side panel, the top of the side panel is fixedly connected to a top panel, the lower surface of the top panel is fixedly connected to a hydraulic cylinder, the movable end of the hydraulic cylinder is fixedly connected to a fixed rod, the end of the fixed rod away from the hydraulic cylinder is fixedly connected to a hot pressing module, a forming groove is provided inside the workbench, and a protective mechanism is provided on the side panel. By providing a protective shell, when the staff performs a picking or placing operation, the electric push rod controls the slide plate to move up, which is used to control the movement of the connecting rod and control the two protective shells to move closer to the middle on the slide rod, so that the hot pressing module is stored in the protective shell, effectively preventing the staff from being scalded by the hot pressing module.

[0004] Regarding the above-mentioned related technologies, the inventors believe that although the above-mentioned device can realize the hot pressing forming of the lunch box and has the effect of preventing burns, the lunch box after hot pressing is prone to excess scraps at the edge due to thermal expansion and contraction and the shape of the paper film, and the overall edge is not smooth, affecting the use. Therefore, when the requirements for the paper box are high, it is necessary to perform additional trimming operations on the lunch box to ensure the quality of the paper box. The additional trimming operations will increase the operating steps, thereby affecting the processing efficiency of the lunch box, and the transfer of trimming by the staff will also increase the burden on the staff. For this reason, we propose a water-resistant and oil-resistant pulp lunch box forming device and method. Summary of the invention
