Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, and more specifically, to a punching device for a heating pad packaging material. Background Art

[0002] In order to ensure the air permeability of the heating pad packaging material, holes are punched on the surface. The diameter of the holes varies according to the air permeability required. The rolling punching method of placing needles on the roller surface is adopted, which is not only efficient but also neatly arranged. However, most of the hole diameters are fixed and cannot be adjusted, and the overall effect is not good. Based on this, the utility model proposes a punching device for heating pad packaging materials. Utility Model Content

[0005] The utility model is further configured as follows: a plurality of first forming protrusions are respectively arranged around both ends of the roller surface of the upper roller.

[0006] The utility model is further configured as follows: the roller surface of the upper roller is provided with a second forming protrusion extending along the axial direction.

[0007] The utility model is further configured as follows: the regulating gasket is made of a non-metallic material without ferromagnetism.

[0008] The utility model is further configured as follows: the soft rubber layer is made of rubber material.

[0009] To sum up, the utility model has the following beneficial effects: the punching device for the heating patch packaging material involved in the utility model can adjust the height of the cone needle extending out of the slot by changing the number of pad adjustment gaskets. Because the diameters of the cone needles in the height direction are not equal, the function of adjusting the punching diameter can be achieved. The punching efficiency is high, the punching hole diameter is adjustable, the overall function is complete, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0014] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0015] Example 1

[0016] See also Figures 1 to 3 As shown, the punching device for a heating patch packaging material involved in this embodiment comprises an upper roller 1 and a lower roller 2, the roller surface of the lower roller 2 is provided with a soft rubber layer 3, the soft rubber layer 3 is made of rubber material, the roller surface of the upper roller 1 is provided with a plurality of adjusting grooves 4, the groove bottoms of the adjusting grooves 4 are buried with magnets 5, a ferromagnetic cone needle seat 6 is provided in the adjusting groove 4, a conical cone needle 7 is provided at one end of the cone needle seat 6 facing away from the magnet 5, at least one adjusting gasket 8 is provided in the adjusting groove 4 between the cone needle seat 6 and the magnet 5, and the adjusting gasket 8 is made of a non-ferromagnetic non-metallic material.

[0017] In this embodiment, the heating patch packaging material to be punched is conveyed between the upper roller 1 and the lower roller 2 in a strip form. When conveyed between the upper roller 1 and the lower roller 2, the cone needle 7 extending out of the slot will pierce the packaging material and penetrate the soft rubber layer 3 to punch holes in the packaging material. The height of the cone needle 7 extending out of the slot is adjusted by changing the number of pads of the adjustment gasket 8. Since the cone needle 7 is conical, the cross-sectional diameters at different heights are not the same.
