Description

Technical Field

[0001] The utility model relates to the technical field of pulp molding machines, in particular to an automatic lifting mechanism for a pulp molding machine fishing pond mold. Background Technique

[0002] According to the Chinese patent publication number CN212316554U, a molding mechanism of a pulp molding device is disclosed. The technical solution is as follows: "It includes a frame. A pulp tank is connected to the frame, and an upper mold is connected above the pulp tank on the frame. The pulp tank is divided into an inner cavity and an outer cavity by a partition. The inner cavity is connected to a feed pipe, and the outer cavity is connected to an overflow pipe. The partition includes a vertical section, and the lower end of the vertical section is connected to a downward inclined section. The downward inclined section inclines towards the center of the pulp tank. A lifting drive component is connected to the lower side of the inner cavity of the pulp tank on the frame. The drive end of the lifting drive component extends into the inner cavity of the pulp tank and is connected to a molding lower mold. A downward inclined surface is arranged on the lower side of the molding lower mold to cooperate with the downward inclined section of the partition. A pulp suction pipe is connected to the lower side of the molding lower mold. The pulp suction pipe passes through the pulp tank and extends to the lower side of the pulp tank. For the molding mechanism of the pulp molding device, the concentration of pulp water is uniform, the pulp water is sufficient, and sediment accumulation and overflow splashing will not occur."

[0003] The above technical solution has the following defects: 1. The lifting drive component oil cylinder is placed below the pulp tank, which will increase the height of the lower components of the machine, and the overall height of the machine will also be raised, which is not conducive to operation; 2. The lifting drive component oil cylinder is placed below the pulp tank, which is inconvenient for later maintenance and replacement; 3. There is a seal at the connection part of the piston rod of the jacking oil cylinder, the pulp suction pipe and the pulp tank. On the one hand, there is a risk of aging and leakage of the sealing ring; at the same time, since grease will adhere to the surface of the piston rod of the jacking oil cylinder mechanism, it will pollute the pulp pond and seriously affect the product quality; 4. The lower mold is carried on the lifting drive component oil cylinder and cannot be mechanically locked, and there is a risk of falling due to its own weight. Therefore, an automatic lifting mechanism for a pulp molding machine fishing pond mold is proposed to solve the above problems. Content of the Utility Model
