[0002] The function of the strapping machine is to make the plastic strapping tape close to the surface of the package being strapped, improve the quality of packaging, enhance the reliability of component transportation, and reduce production costs. However, there is a common problem in the existing automatic packaging system. The position of the strapping tape cannot be accurately positioned, and the strapping tape will be skewed during the packaging process, which brings greater risks to the transportation and loading and unloading of the product;

[0003] In the production process of PP recycled strapping tape, it is necessary to use a correction device to assist production. For example, a Chinese patent discloses a PP recycled strapping tape correction device (authorization announcement number CN209905145U). This patented technology can solve the problem of strapping tape skew through the positioning and limiting functions of the limit device;

[0004] However, the above-disclosed deviation correction device still has some defects when in use: when in use, the device simply corrects the deviation through the limit device, and cannot compress the strapping tape for protection, nor can it adjust the protection position according to the thickness of the rolled strapping tape, which affects the convenience of deviation correction. Therefore, those skilled in the art provide a deviation correction device for a PP recycled strapping tape production line to solve the problems raised in the above background technology.
