Description

Technical Field

[0001] The utility model relates to the technical field of round die-cutting machines, in particular to a round die-cutting machine convenient for waste removal. Background Technique

[0002] All kinds of die-cutting processes are based on the die-cutting machine, so the die-cutting machine closely related to us is the most important component of die-cutting, generally divided into two die-cutting forms: flat-bed and round-bed. The selection of the die-cutting machine is usually determined by the complexity and quantity of the order. Each die-cutting machine has its own advantages and the production orders it is suitable for. For example, the round-bed die-cutting machine is suitable for the production of large-size cardboard and large-batch orders; while the flat-bed die-cutting machine is more suitable for the production of complex die-cutting tool layouts and small-batch orders, but it cannot reach the level of the round-bed die-cutting machine in terms of production speed and cardboard processing size.

[0003] The existing round-bed die-cutting machine consists of a frame, a feeding device, a die-cutting device and a waste box. For the existing round-bed die-cutting machine, during the die-cutting process, there is a lack of a fixing mechanism, and the material is prone to deviation during the reciprocating movement, reducing the accuracy of the die-cutting position, affecting the quality of the carton, and resulting in a high waste rate; hundreds of die-cut cardboard sheets are stacked together, and the removal of the waste paper edges and middle chip scraps needs to be completed manually, with high labor intensity and low work efficiency.

[0004] Based on this, this scheme proposes a round-bed die-cutting machine convenient for waste removal. Content of the Utility Model
