In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example 1:
as shown in fig. 1 and 2: the embodiment provides a method for punching a hole in a non-metal elastic material, wherein the non-metal elastic material 1 can be one layer or multiple layers in a composite mode, preferably is an air-tight or slightly air-tight water-repellent material film or a composite material of the water-repellent material film and a non-woven fabric, the water-repellent material film is preferably made of a PP material, a PA material, a PVC material, an EVA material, a PU material, a TPU material, a PET material, a PE material, a polyester material or a nylon material, and the non-woven fabric is preferably at least one of a polypropylene (PP) non-woven fabric, a Polyester (PET) non-woven fabric, a Polyamide (PA) non-woven fabric, a viscose non-woven fabric, an acrylic non-woven fabric, a polyethylene (HDPE) non. Before punching, the non-elastic area 2 needs to be formed on the non-metal elastic material 1, then the non-elastic area 2 is punched, the diameter of the holes can be very small or even reach micron level, the number of the holes 3 in one non-elastic area 2 can be one or more, and the actual diameter and the number are determined according to the required size of the non-elastic area for air permeability. The number of the non-elastic regions 2 can be several, and the non-elastic regions are uniformly distributed on the non-metal elastic material 1 in an array. Of course the non-elastic regions 2 may also be distributed non-uniformly, as long as the diameter and number of holes made meet their requirements for the amount of ventilation. The inelastic zone can be selected from a circle, a ring, an ellipse, an elliptical ring, a polygon and a polygonal ring, the inelastic zone can also adopt the nesting of the rings, and the punched hole can be selected from a circle, an ellipse or a polygon. Preferably, when the inelastic zone 2 is circular or annular, the corresponding punched holes 3 are circular holes, when the inelastic zone 2 is elliptical or elliptical annular, the corresponding punched holes 3 are elliptical holes, and when the inelastic zone 2 is polygonal or polygonal annular, the corresponding punched holes 3 are polygonal holes, so as to ensure that the edge distances between the holes 3 and the inelastic zone 2 are consistent, and the holes 3 are not easy to deform along with the extension of the non-metallic elastic material 1, that is: the pores 3 do not undergo a change in pore size as the non-metallic material is stretched in its entirety or partially.
Further, the inelastic regions 2 may be formed by partially losing the elasticity of the nonmetallic elastic material 1 by a hot-melt method, a high-frequency welding method, an ultrasonic welding method, or an adhesive method. Specifically, the non-elastic region 2 may be thermally fused on the non-metal elastic material 1 by using a thermal fusion machine, a cross section of a thermal fusion portion of the thermal fusion machine is matched with the non-elastic region 2, a punching needle of the thermal fusion machine is located inside the thermal fusion portion, and after the thermal fusion portion is contacted with the non-metal elastic material 1, the punching needle extends out of the thermal fusion portion and pierces through the non-elastic region 2.
Example 2:
as shown in fig. 1 and 3: this embodiment is different from embodiment 1 in that: the method comprises the steps of fixedly connecting a non-elastic sheet 4 with a non-metal elastic material 1 by using a hot melting method, a high-frequency welding method, an ultrasonic welding method or a bonding method, forming a non-elastic area 2 by the non-elastic sheet 4 after the non-elastic sheet 4 is stably connected with the non-metal elastic material 1, and then punching a hole in the non-elastic sheet 4 and simultaneously penetrating through the non-metal elastic material 1. Of course, it is also possible to make a preformed hole in the non-elastic sheet 4 and then punch the hole 3 in the non-metallic elastic material 1 through the preformed hole. Other technical features and effects are the same as those of embodiment 1, and are not described herein again.
The invention arranges the non-elastic area 2 on the non-metal elastic material 1 by using a hot melting method, a high-frequency welding method, an ultrasonic welding method or a bonding method, wherein the non-elastic area 2 can be formed by the non-metal elastic material 1 or by adding the non-elastic sheet 4, then the non-elastic area 2 is perforated, and the hole 3 needs to penetrate through the non-elastic sheet 4 and the non-metal elastic material 1. Because the non-elastic area 2 can not deform along with the extension of the non-metal elastic material 1, the shape and the size of the hole 3 in the non-metal elastic material can be effectively ensured, and the ventilation quantity of the non-metal elastic material 1 is stable.
The invention solves the technical problem that the holes on the non-metal elastic material can be stretched, deformed and enlarged when the non-metal elastic material is stretched, so that the air permeability of the non-metal elastic material 1 can be effectively controlled to be required, and guarantees are provided for further utilizing the perforated non-metal elastic material 1 to manufacture products such as heating masks, self-heating bags, warming pastes and the like.
The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed.
