Plastic film code spraying device

The invention belongs to the technical field of packaging machinery, and relates to a plastic film code spraying device comprising a left wallboard and a right wallboard which are arranged to be parallel to each other. A reeling shaft is rotatably arranged at the front end between the left wallboard and the right wallboard. An unreeling shaft is rotatably arranged at the rear end between the left wallboard and the right wallboard. An aluminum plastic reeling film is wound on the unreeling shaft. A first rubber compression roller is rotatably arranged on the aluminum plastic reeling film. A second rubber compression roller is rotatably arranged on the reeling shaft. A second guide roller and an eleventh guide roller are rotatably arranged at the upper part between the unreeling shaft and the reeling shaft. A fifth guide roller, a sixth guide roller, a seventh guide roller, a second rubber guide roller and an eighth guide roller are rotatably arranged at the lower part between the unreeling shaft and the reeling shaft. The plastic film code spraying device is used for solving soft plastic packaging products with subtle difference in series products so that production cost of enterprises is greatly reduced and order delivery time of clients is also greatly shortened.
