Technical Field
[0001] The invention relates to the technical field of pulp molding processing, in particular to an air suction side punching machine for pulp molding three-dimensional products. Background Art
[0002] With the rapid development of the pulp molding industry and the increasing demand for diverse functionalities in three-dimensional products, adding notches to the sides of three-dimensional molds has become a key design trend to meet the assembly and coordination requirements of composite products. The vacuum side punch, with its efficient and precise side punching capabilities, has become a key piece of equipment to address this need.
[0003] However, traditional side punching dies for paper and plastic products often rely on independent hydraulic presses for installation and operation, exposing numerous limitations in actual production applications. First, the molds require dedicated hydraulic press equipment, which not only increases equipment purchase costs but also prevents flexible allocation of equipment resources, significantly increasing the company's production costs. Second, during the production process, limited by the fixed matching mode of equipment and molds, wiring flexibility is poor, making it difficult to quickly respond to the production needs of different products, resulting in redundant manpower and low production efficiency. Third, the side punching mold has a complex structure, a long processing and manufacturing cycle, and high process precision requirements, further increasing mold R&D and production costs. In addition, during the production process, traditional side punching molds are prone to mold wear and reduced punching accuracy. Frequent fault repairs and debugging lead to increased downtime, seriously restricting overall production efficiency.
[0004] Therefore, in order to address the technical bottleneck of side punching molds for traditional paper-plastic products, it is urgent to carry out technological innovation based on existing devices and develop a low-cost, flexible, efficient and stable side punching device for pulp-molded three-dimensional products to promote the high-quality development of the pulp molding industry.

[0029] The staff connects the compressed air to the vacuum generator 5, and connects it to the cylinder 6, vacuum base 14, punching manual valve 3 and suction manual valve 4 through the vacuum generator 5. Then, after placing the product on the vacuum positioning block 12, the suction manual valve 4 is pushed to firmly suck the product, and then the punching manual valve 3 is pushed to drive the top block 8 to move through the output end of the cylinder 6.
