Technical Field

[0001] The utility model relates to the field of die-cutting equipment, in particular to automatic die-cutting equipment for sheet materials. Background Art

[0002] Die-cutting machines are generally called die-cutting machines, cutting machines, and CNC punching machines. They are mainly used for die-cutting (full cutting, half cutting), creasing, and hot stamping of some corresponding non-metallic materials, self-adhesive stickers, EVA, double-sided tape, electronics, mobile phone pads, etc. Therefore, manufacturers will use automatic die-cutting equipment to cut sheet materials when producing and preparing some sheet materials (i.e. sheet packaging materials, such as foam, cardboard, pearl cotton, etc.).

[0003] However, the current automatic die-cutting equipment still has some shortcomings. For example, the existing automatic die-cutting equipment has a poor positioning effect. Since the sheet materials to be cut will be stacked when they are cut, the stacked sheet materials are prone to position shift when the die-cutting equipment is cutting the sheet materials, which easily increases the probability of defective products and easily interferes with the subsequent processing of the staff, resulting in certain usage defects.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structural deficiencies and provides an automatic die-cutting device for sheet materials. Utility Model Content

By setting the positioning clamping plate 51 and the workbench 1 as a sliding structure, the positioning clamping plate 51 is more stable and smooth when moving forward and backward along the top of the workbench 1. An elastic buffer mechanism 55 is fixedly installed on the inner side of the positioning clamping plate 51, and the end of the elastic buffer mechanism 55 is fixedly connected with a positioning plate 56. The end of the elastic buffer mechanism 55 is fixedly connected to the inner side of the positioning clamping plate 51, and the other end of the elastic buffer mechanism 55 is fixedly connected to the outer side of the positioning plate 56, and the positioning plate 56 forms an elastic structure with the positioning clamping plate 51 through the elastic buffer mechanism 55. By setting the positioning plate 56 and the positioning clamping plate 51 as an elastic structure, the positioning plate 56 will not cause wear to the sheet material when positioning and clamping the sheet material.

[0023] like Figure 1 and Figure 3As shown, the support column 6 is fixedly installed at the bottom of the workbench 1 symmetrically, and a top plate 7 is fixedly installed on the top of the support column 6, and a punching cylinder 8 is installed on the top of the top plate 7 by bolts, and the extended end of the punching cylinder 8 is fixedly connected with a punching assembly 9 by bolts, and the punching assembly 9 includes a bearing plate 91, a punching tool 92, a limiting mechanism 93, a fourth connecting plate 94 and a limiting spring 95, and the punching tool 92 is fixedly installed at the bottom of the bearing plate 91, and the limiting mechanism 93 is symmetrically installed at the bottom of the bearing plate 91, and the limiting mechanism 93 includes a first connecting plate 931, a second connecting plate 932, a connecting seat 933, a second fixing plate 934, a connecting rod 935, a limiting roller 936 and a third connecting plate 937, and the inner side of the first connecting plate 931 is rotatably connected to the second connecting plate 932 through a connecting shaft, and the bottom of the second connecting plate 932 is fixedly installed with a connecting seat 933, and the bottom of the connecting seat 933 is symmetrically installed with a second fixing plate 934, and the second fixing plate 934 is rotatably connected to the inside of the second fixing plate 934, and the end of the connecting rod 935 is fixedly installed.
