Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, and specifically relates to an automatic die-cutting machine for step-by-step cutting of die-cut products. Background Art

[0002] An automatic die-cutting machine is a cutting device, which is widely used in multiple industries such as packaging, printing, electronics, pharmaceuticals, chemicals, and food. The automatic die-cutting machine uses metal die-cutting tools to cut materials into specific shapes through automated control, and is mainly used for die-cutting processes of various materials such as non-metallic materials, self-adhesive labels, and electronic components.

[0003] Currently, the structure of a die-cutting machine is generally similar to that of a die-cutting machine disclosed in a patent application with the application number "CN201720137538.6", including a feeding roller, a pinch roller, a die-cutting mechanism, and a receiving roller. The die-cutting mechanism includes an upper die base, a lower die base, a die-cutting knife, and a pressing cylinder. The die-cutting knife is located at the front end of the upper die base, and the pressing cylinder drives the upper die base to move relative to the lower die base. It also includes a swing arm and a swing mechanism. One end of the swing arm is hinged to the upper die base through a hinge shaft, and the other end is sleeved on the transmission shaft of the die-cutting knife. The swing mechanism drives the swing arm to swing around the hinge shaft. However, this utility model is prone to deformation under the influence of mechanical stress when cutting complex-shaped or large-sized products, thereby affecting the appearance quality of the products, and the cutting accuracy will decrease, further affecting the functions of the products.

[0004] Therefore, the utility model proposes an automatic die-cutting machine for step-by-step cutting of die-cut products to solve the above problems. Summary of the Utility Model
