Description

Technical Field

[0001] The utility model relates to packaging equipment, in particular to a high-efficiency follow-up cam corner inserting mechanism for an automatic packaging machine. Background Art

[0002] During the sealing operation of a packaging bag, in order to form a three-dimensional structure in the packaging bag, a corner inserting mechanism is required to perform corner inserting treatment on both sides of the packaging bag. For example, the patent document CN218537347U discloses a corner inserting mechanism, which includes a frame, and also includes a driving shaft and a driven shaft. The driving shaft and the driven shaft are arranged in parallel on the frame from bottom to top. There are an upper sealer and a lower sealer, and the upper sealer and the lower sealer are respectively arranged on the driven shaft and the driving shaft. There is a cam, which is fixed on the driven shaft, and there is a convex block along its axial direction on its inner side. There is an annular groove on the outer periphery of the cam, and the annular groove forms a C-shaped groove at the convex block. There is a corner inserting member, which is horizontally slidably connected to the frame, and a guide is arranged on the corner inserting member to cooperate with the annular groove for sliding. Through the cooperative design of each structure, the transfer link after the corner inserting operation of the packaging bag is reduced. After the corner inserting operation of the bag, the sealing operation can be completed immediately. It can ensure that the corner inserting and sealing of the bag are neat and beautiful after forming, and improve the packaging quality. However, the corner inserting guide structure of this corner inserting mechanism is relatively complex, and it is easy to have a problem of asynchronous operation with the sealing mechanism, affecting the sealing quality. Therefore, it is necessary to optimize the structure of this corner inserting mechanism to overcome the above defects. Summary of the Utility Model
