Description

Technical Field

[0002] The buffer paper forming machine is mainly aimed at the needs of in-box packaging. The roll of paper is folded and processed into a buffer paper pad with filling, winding, fixing and buffering functions. During the production process, if the roll of raw material has a multi-layer folded layer structure, the final buffer paper pad will have better buffering function. The buffer paper forming machine needs to use metal plates as the shell during the production process. The metal plates need to be polished during the processing process. Usually, a polishing device is required to produce the metal shell of the buffer paper forming machine.

[0003] However, during the use of the traditional grinding device for producing the metal shell of the buffer paper forming machine, the metal sheet used as the shell is mainly placed on the workbench, the sheet is limited and fixed by a fixing mechanism, and then the outer surface of the metal sheet is driven by the grinding head through the driving device to grind. After the metal sheet is polished, the outer side of the metal sheet is bent according to the shape requirements of the shell to form a connecting surface that is convenient for the shell to be docked. However, the traditional grinding device has a single function and cannot bend the metal sheet. The operator needs to use additional equipment for processing, and the operation steps are cumbersome, which leads to the problem of low shell production efficiency.
