[0002] The flexible packaging printing and slitting machine is a kind of mechanical equipment widely used in the flexible packaging industry. It is mainly used to slit wide flexible packaging materials into multiple narrow materials. During the operation of the current slitting machines on the market, it is difficult to flexibly adjust the cutting depth of the slitting knife according to the actual thickness of the flexible packaging material. This design limitation makes the machine mainly suitable for processing flexible packaging of a specific thickness, which greatly limits its extensiveness and flexibility in practical applications, and reduces the versatility and use efficiency of the equipment; in addition, when the existing slitting machine is in operation, the position of the slitting knife installed on it is often fixed, and it lacks the ability to quickly adjust to meet the needs of different slitting sizes. This fixed design makes it difficult for the machine to flexibly respond to the diverse flexible packaging slitting needs on the market, and thus cannot meet the user's requirements for efficient and precise cutting of products of different specifications and sizes. Therefore, we propose an automatic device for a flexible packaging printing and slitting machine. Utility Model Content
