Production safety is always the top priority in production and operation. The die-cutting machine used for raw material cutting adopts chain-type transmission and automatic conveying. In practice, the chain at the end is easy to be hinged to the worker's work clothes, which poses an unsafe hazard. In the prior art, for example, the invention patent with application number 201320063937.4 includes a die-cutting machine body, a transmission chain and a sprocket.
