[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Refer to the instruction manual Figure 1-5 The present invention provides a graphene composite heating fabric, comprising a graphene heating film 1, wherein a plurality of circular holes 2 are processed at the top of the graphene heating film 1, and a ventilating tube 3 is penetrated inside each circular hole 2, and an antibacterial layer 4, a reinforcement layer 5 and a protective layer 6 are sequentially arranged at the top and bottom of the graphene heating film 1 from the inside to the outside;

[0035] Specifically, the antibacterial layer 4 includes a mesh cloth 41, and two mesh cloths 41 are respectively arranged at the top and bottom of the graphene heating film 1, the reinforcement layer 5 includes a mesh cloth 51, and the two mesh cloths 51 are respectively arranged on the outer walls of the two mesh cloths 41, the protective layer 6 includes a wear-resistant cloth 61, and the two wear-resistant cloths 61 are respectively arranged on the outer walls of the two mesh cloths 51, the two wear-resistant cloths 61, the two mesh cloths 41 and the two mesh cloths 51 are all sleeved on the outside of the multiple breathable tubes 3, and the surface of the wear-resistant cloth 61 is hot-pressed to form a plurality of breathable holes 62;

[0036] Next, a slider 63 is fixedly sewn on the adjacent sides of the two wear-resistant cloths 61 , and a slide rail 64 is fixedly sewn on the adjacent side of the mesh cloth 51 51 , and the slider 63 is slidably disposed in the slide rail 64 .

[0037] The graphene heating film 1 is powered on to generate heat, and the heat is conducted through the antibacterial layer 4, the reinforcement layer 5 and the protective layer 6, so that the graphene composite heating fabric can generate heat stably, and a plurality of air permeable tubes 3 are arranged in the graphene heating film 1, and the plurality of air permeable tubes 3 are used to support and ventilate the inside of the graphene composite heating fabric, so that the air circulation speed of the graphene composite heating fabric is accelerated, and the heat can be dissipated more effectively, so that the surface temperature of the fabric is relatively reduced, and the heating effect is weakened. When the wear-resistant fabric 61 is pulled upward, The multiple air holes 62 on the wear-resistant cloth 61 are staggered with the multiple air tubes 3, and the wear-resistant cloth 61 and the reinforcement layer 5 are adhered together using the Velcro fleece surface 65 and the Velcro sticky surface 66. At this time, the wear-resistant cloth 61 can block the air tube 3, thereby reducing the air permeability of the graphene composite heating cloth. When the air permeability is reduced, the heat dissipation is blocked, which will cause the temperature of the cloth to continue to rise, thereby improving the heating effect of the cloth. By adjusting the position of the wear-resistant cloth 61, the heating effect of the graphene composite heating cloth can be quickly adjusted.

[0038] In this embodiment, the surfaces of the two wear-resistant cloths 61 that are close to each other are fixedly sewn with multiple Velcro surfaces 65, and the surfaces of the two mesh cloths 51 that are far away from each other are fixedly sewn with the same number of Velcro adhesive surfaces 66 as the Velcro surfaces 65, and the Velcro adhesive surfaces 65 are bonded to the Velcro adhesive surfaces 66.

[0039] In this embodiment, a filter screen 7 is fixedly sewn on the surface of the two wear-resistant cloths 61 on the side away from each other. The filter screen 7 is arranged on the outside of the wear-resistant cloth 61. The filter screen 7 can filter dust and impurities in the outside air to prevent the dust and impurities from clogging the air tube 3 and affecting the air permeability of the graphene composite heating cloth.

[0040] In this embodiment, if Figure 6As shown, the mesh cloth 41 is woven by a plurality of transverse woven wires 42 and a plurality of longitudinal woven wires 43 through a warp knitting machine, and a plurality of through holes 44 having the same number as the breathable tube 3 are formed between the transverse woven wires 42 and the longitudinal woven wires 43. The transverse woven wires 42 are silver ion antibacterial fibers, which can effectively inhibit the growth and reproduction of microorganisms such as bacteria and molds. The longitudinal woven wires 43 are spandex fibers, which have high elasticity, can quickly return to their original shape after stretching, are not easily deformed, and can therefore be reused.

[0041] In this embodiment, if Figure 7 As shown, the mesh cloth 2 51 is made of multiple fiber filaments 1 52 and multiple fiber filaments 2 53 woven by a warp knitting machine, and multiple through holes 2 54 of the same number as the breathable tube 3 are formed between the fiber filaments 1 52 and the fiber filaments 2 53. The fiber filaments 1 52 are PBT elastic fibers, which have good elasticity, wear resistance and chemical resistance, and can therefore recover quickly after deformation. The fiber filaments 2 53 are polyester fibers, which have high strength and good tensile and tear resistance. The resulting fabric is tough and durable, can withstand large external forces, and is not easily damaged, and is therefore suitable for use in the present invention.

[0042] The preparation process of the above-mentioned graphene composite heating fabric has the following specific preparation steps:

[0043] Step 1: using a warp knitting machine to weave a plurality of transverse knitting threads 42 and a plurality of longitudinal knitting threads 43 into a mesh cloth 1 41, and to weave a plurality of fiber threads 1 52 and a plurality of fiber threads 2 53 into a mesh cloth 2 51;

[0044] Step 2: Use the installation mechanism to heat-press a plurality of circular holes 2 on the graphene heating film 1, then place a plurality of air-permeable tubes 3 in a plurality of electric clamps 14 respectively, and then transport and install the plurality of air-permeable tubes 3 in the plurality of circular holes 2 together;

[0045] Step three: Place mesh cloth 1 41 , mesh cloth 2 51 and wear-resistant cloth 61 on the outer wall of the graphene heating film 1 from the inside out, and use a warp knitting machine to sew the graphene heating film 1 , two mesh cloths 1 41 , two mesh cloths 2 51 and two wear-resistant cloths 61 together to obtain a graphene composite heating fabric.

[0046] Among them, Figure 8-9As shown, the structure of the installation mechanism in the preparation method is: it includes a processing table 8, a bracket 9 is fixedly provided on the top of the processing table 8, and a laser transmitter 10 for opening holes in the graphene heating film 1 is provided at the bottom of the bracket 9. Specifically, the laser transmitter 10 uses the AOC series. This type of laser transmitter 10 has a wavelength of 355nm, has precise power consumption control and extremely high precision, can achieve one-time cutting, precise cutting and fast cutting, and has an ultra-high cutting accuracy of ±0.02mm, so it is suitable for the opening processing of the graphene heating film 1, and a feeding rack 11 is provided in front of the bracket 9. Two top plates 12 are provided at the bottom of the feeding rack 11. The tops of the two top plates 12 are connected to the feeding rack 11 through multiple electric push rods 13. Specifically, the electric push rod 13 uses the M909 type, and the bottoms of the two top plates 12 are fixed with multiple electric clamps 14 for fixing the breathable tube 3. Specifically, the electric clamp 14 uses PZN+80-1.

[0047] The bottom end of the bracket 9 is installed on the top of the processing table 8 through a linear module 15, and the top of the laser transmitter 10 is installed on the bracket 9 through a linear module 2 16. Specifically, the linear module 15 and the linear module 16 are 32RSA-ST. The stroke of this type of linear module 15 and linear module 16 can reach 914mm, and the maximum force is 6036N, so it is suitable for use in the present invention.

[0048] By placing air cylinders 3 on the electric clamps 14 at the bottom ends of the two top plates 12, after placing the graphene heating film 1 on the processing table 8, first use the linear module 2 16 to drive the laser emitter to move, and use the laser emitter to process multiple circular holes 2 on the graphene heating film 1, and then use the linear module 1 15 to drive the bracket 9 and the feeding rack 11 to move above the graphene heating film 1, and then use the electric push rod 13 to drive the top plate 12 connected thereto to move downward, and insert multiple air cylinders 3 into the multiple circular holes 2 at one time, and the air cylinder 3 and the graphene heating film 1 are first glued together by glue, and finally a warp knitting machine is used to sew the graphene heating film 1, two mesh cloths 1 41, two mesh cloths 2 51 and two wear-resistant cloths 61 together. After processing a piece of graphene heating film 1, a new graphene heating film 1 can be placed, and during the processing, the staff has sufficient time to place a new air cylinder 3, thereby improving the processing efficiency.

[0049] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
