Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing equipment, and particularly relates to a punching machine for non-woven fabric processing. Background Art

[0002] In the non-woven fabric processing technology, the punching process is mainly used to enhance the air permeability of the material, achieve specific pattern designs, or facilitate subsequent processing operations such as sewing and binding. In the actual production process, the traditional non-woven fabric punching process mainly relies on mechanical punching, laser cutting, hot melt punching, etc. Among them, the mechanical punching method forms holes by die extrusion, and burrs are easily formed at the edges of the holes during stamping, which affects the processing quality. Therefore, a punching machine for non-woven fabric processing is proposed to solve this problem. Content of the Utility Model

[0003] In view of this, the utility model provides a punching machine for non-woven fabric processing, which can drive the connecting structure through the driving structure to make the punching head of the punching die cooperate with the bottom die base for punching. After the punching head completes the punching operation, the heating ring performs heat treatment on the burrs at the punching edge, thereby effectively avoiding the situation that the punching burrs affect the production quality.

[0004] To solve the above technical problems, the utility model provides a punching machine for non-woven fabric processing, including a bottom die base and a punching structure corresponding to the bottom die base. The punching structure includes a punching die head corresponding to the bottom die base, a driving structure for driving the punching die head to act, and a connecting structure connecting the punching die head and the driving structure.

[0005] The punching die head includes a punching head corresponding to the bottom die base. A connecting protrusion is provided at the upper end of the punching head, and a heat-sealing component is fixedly sleeved around the connecting protrusion.

[0006] The heat-sealing component includes a heat-insulating sleeve sleeved around the outer periphery of the connecting protrusion. A heating ring is sleeved around the outer periphery of the heat-insulating sleeve. The shape of the heating ring corresponds to the shape of the punching head. A limiting collar is fixedly provided on the heat-insulating sleeve at the upper part of the heating ring. The outer periphery of the limiting collar is circularly arranged, and its cross-section is larger than the cross-section of the punching head.

[0007] A plurality of slots are provided on the limiting collar, and fasteners are provided in the slots. The fasteners pass through the limiting collar and the heat-insulating sleeve and are connected to the connecting protrusion.

[0008] The driving structure includes a mounting frame and a telescopic drive fixedly provided on the mounting frame.

[0009] The connecting structure includes a coupling provided at the output end of the telescopic drive. The other end of the coupling is fixedly connected with a connecting rod. A guiding hole corresponding to the connecting rod is provided at the lower part of the mounting frame. The connecting rod passes through the guiding hole, and a connecting seat is provided at this end. The connecting seat is fixedly connected with the connecting protrusion.

[0010] The lower part of the heat insulation sleeve is arranged in an annular gasket shape, and the upper part is arranged in a sleeve shape.

[0011] A wire passing hole is also provided on the limit collar.

[0012] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0013] 1. The driving structure drives the connecting structure to make the punching head of the punching die head cooperate with the bottom die base for punching. After the punching operation of the punching head is completed, the heating ring performs heat treatment on the burrs at the punching edge, thereby effectively avoiding the situation that the punching burrs affect the production quality.

[0014] 2. Fix the mounting frame on the non-woven fabric processing equipment that needs to perform punching operations. The bottom die base and the punching head are installed corresponding to each other up and down. Further, the telescopic drive drives the connecting structure to move, and then the connecting rod of the connecting structure moves in the guiding hole to avoid the connecting rod shifting during the stamping operation and causing equipment damage. Further, the punching head moves to punch the non-woven fabric. After the punching head and the bottom die base cooperate to complete the punching action, the telescopic drive continues to push downward, and then the heating ring moves to the non-woven fabric opening position to perform heat treatment on the burrs at the opening position, thereby removing the burrs at the opening.

[0015] 3. The outer periphery of the heating ring, the outer periphery of the punching head, and the heat insulation sleeve are arranged with the same annular gasket-shaped position structure. The inner periphery of the heat insulation sleeve is arranged in cooperation with the outer periphery of the connecting protrusion, thereby isolating the heat generated by the heating ring during use and avoiding excessive heat conduction to the punching head.
