Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery and equipment, and particularly relates to a sealing part adjusting device with high automation degree and high synchronization. Background Technique

[0002] Many products, such as sanitary napkins, disposable wet wipes, etc., are packaged using plastic film packaging, and sealing and forming are required during packaging. In the existing sealing machines, a triangular plug board is inserted into the packaging bag, and then the extrusion forming is achieved by the extrusion of the discharged constant pressure component to complete the main actions of the sealing and forming of the plastic film packaging bag. In addition, the position of the rear baffle and the cylinder is adjusted through the rear baffle adjusting component to prevent the product from overshooting and falling.

[0003] However, the existing sealing machine equipment still has certain defects: among them, the triangular plug board component is driven by a cylinder. When changing the product size, the screw rod needs to be adjusted to adjust the position of the cylinder so as to indirectly adjust the final position of the triangular plug board. The discharged constant pressure part is also driven by a cylinder. Therefore, in the prior art, whenever the size of the packaged product is changed, each component of the sealing and forming needs to manually adjust the screw rod, which leads to troublesome mold change and long required time. Secondly, the discharged horizontal pressure plate driven by the cylinder and the triangular plug board lack synchronization, which is not conducive to debugging the machine when changing the mold and debugging the equipment. In addition, the rear baffle adjusting component uses a handwheel to connect the screw rod, and the screw rod is adjusted manually to adjust the rear baffle. Summary of the Utility Model
