DETAILED DESCRIPTION

[0053] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than 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.

[0054] like Figure 1-Figure 14As shown, a process for making a tensioning rod provided in this embodiment includes the following steps: weaving a dense woven area 100 and a patterned woven area 200 in sequence according to preset sizes, wherein the weaving density of the patterned woven area 200 is lower than that of the dense woven area 100; locally applying glue along the surface of the dense woven area 100; after the gluing is completed, cutting is performed on the dense woven area 100 as required to form a tensioning rod 400; wherein the patterned woven area 200 between any two adjacent sections of the dense woven area 100 is the height of the tensioning rod 400.

[0055] It should be noted that the reinforcement manufacturing process provided in the present embodiment can adopt a new weaving process and a local gluing process, which can save cost and weight and prevent material waste on the basis of realizing the manufacturing of the reinforcement 400; specifically, the dense weaving area 100 and the pattern weaving area 200 are woven in sequence according to the preset size, and the woven original cloth fabric can be made of cotton cloth, polyester cloth or nylon cloth, etc. In the weaving stage, the dense weaving area 100 and the pattern weaving area 200 are woven with the corresponding width according to the required product size, and the dense weaving area 100 is used as the local gluing position of the end of the reinforcement 400, that is, the dense weaving area 100 forms a cover cloth 500 and a base cloth 600 respectively. Connection, by making the weaving density of the patterned weaving area 200 lower than that of the densely woven area 100, that is, the patterned weaving area 200 serves as the height side wall position of the reinforcement 400, and utilizing the low weaving density, it is possible to reduce the weight of the reinforcement 400 and improve the air permeability while ensuring the strength and toughness of the reinforcement 400; further, by locally applying glue on the surface of the densely woven area 100, glue can be applied at intervals along the extension direction of the densely woven area 100. When the gluing is completed, the reinforcement 400 is formed by cutting at the densely woven area 100. When the reinforcement 400 needs to be installed on the inflatable product, it only needs to be connected using the glued position.

[0056] Optionally, the densely woven area 100 and the patterned woven area 200 can be woven in a manner that the weft yarns are arranged in parallel, and the warp yarns are woven with the weft yarns in a V-shaped bend sequence; wherein the weft edge formed by weaving can be formed by rotating the weft yarn around the outer warp yarn and returning it back toward the other side, and this weft edge resists wear because the returned weft yarn locks the outer warp yarn.

[0057] The reinforcement manufacturing process provided in this embodiment includes the following steps: weaving a dense woven area 100 and a pattern woven area 200 in sequence according to a preset size, wherein the weaving density of the pattern woven area 200 is lower than that of the dense woven area 100; locally applying glue along the surface of the dense woven area 100; after the glue application is completed, cutting is performed on the dense woven area 100 according to needs to form a reinforcement 400; wherein the pattern woven area 200 between any two adjacent sections of the dense woven area 100 is the height of the reinforcement 400; by adopting a weaving method The method uses different weaving densities to form a dense weaving area 100 and a pattern weaving area 200, so that the formed tensioning rod 400 has the advantages of being strong, light and breathable. The surface of the dense weaving area 100 forming the surface of the tensioning rod 400 can also be partially coated with glue, which saves cost, reduces weight, ensures material waste, and alleviates the technical problems in the prior art that the surface of the tensioning rod 400 is fully coated with glue, resulting in an increase in the cost and weight of the inflatable product, and the tensioning rod 400 will block the airflow and affect the inflation and deflation efficiency.

[0058] On the basis of the above embodiments, further, in a preferred embodiment of the present invention, the step of locally applying glue along the surface of the dense woven area 100 also includes: determining the local gluing range according to the area range of the welding points set for the inflatable product; the local gluing of any two adjacent groups of dense woven areas 100 are arranged symmetrically about the center line of the patterned woven area 200; and drying the local glue to form an adhesive layer 300.

[0059] In this embodiment, according to the size of the welding points set for the inflatable product, two groups of corresponding patterns of glue are applied in the dense woven area 100, that is, each dense woven area 100 has two groups of local glue application, and the two groups are symmetrically arranged with respect to the center line of the dense woven area 100. The two groups of glue application points can be distributed in an orderly manner, and the shape can be regular or based on a mold. Glue is applied according to the shape of the mold, and the mold can be a regular or irregular pattern, and the width of the glue or film can be different; that is, the structure and shape of the glue application points can be set according to a benchmark that is convenient for operation during the manufacturing process.

[0060] In a preferred embodiment of the present invention, the local gluing includes local point gluing, local line gluing, local surface gluing, local casting or local film pasting.

[0061] In this embodiment, the local glue coating can be performed by means of a mold at the same time, or it can be symmetrically arranged on two opposite sides of the tie rod 400 by means of mold casting.

[0062] Optionally, there are multiple choices for the sticky material for local glue coating, such as: TPE (Thermoplastic Elastomer), TPU (Thermoplastic polyurethanes), TPR (Thermo-Plastic-Rubber material), TPV (Thermoplastic Vulcanizate), PVC (Polyvinyl chloride), TPO (Thermoplastic polyolefin), TPVC (polyvinyl chloride thermoplastic elastomer), TPVE (phenyl vinyl ether), EVA (Ethylene Vinyl Acetate), etc.; preferably, the local glue coating can be local glue coating or local film application of TPU or PVC.

[0063] like Figure 1-Figure 4 As shown, it should be noted that for different inflatable products, the shape of the tie rod 400 can be various, such as C-shaped tie rod and ring-shaped tie rod; for the C-shaped tie rod manufacturing process, in a preferred embodiment of the present invention, the following steps are also included: weaving to form two sections of dense woven areas 100, and weaving a patterned woven area 200 between the two sections of dense woven areas 100; cutting within the two sections of dense woven areas 100 to form a C-shaped tie rod with a long mesh structure.

[0064] In this embodiment, two sections of densely woven areas 100 and one section of patterned woven area 200 are used as a stage of the door width cycle, that is, the two sections of densely woven areas 100 are used as the two ends of the tie rod 400, and one section of patterned woven area 200 is used as the height side wall of the tie rod 400. The two sections of densely woven areas 100 can be bent relative to the patterned woven area 200, that is, after the two sections of densely woven areas 100 are connected with the cover cloth 500 and the base cloth 600 respectively, the patterned woven area 200 just forms the height side wall of the tie rod 400. By using a low weaving density, the weight of the tie rod 400 can be reduced and the breathability can be improved.

[0065] In a preferred embodiment of the present invention, the step of cutting in the dense woven area 100 according to demand also includes: weaving the dense woven area 100 and the pattern woven area 200 in sequence in an intermittent weaving manner; cutting along the center line of the dense woven area 100; using the two sections of the cut dense woven area 100 on the opposite sides of the pattern woven area 200 as the tie rod 400 structure to form a long mesh structure of the tie rod 400.

[0066] In the present embodiment, during the cutting process of the C-shaped reinforcement, in order to ensure a circular weaving method within the width, the dense weaving area 100 and the pattern weaving area 200 are woven in sequence by utilizing an interval weaving method, wherein the widths of any two adjacent groups of dense weaving areas 100 are the same. In order to ensure that the specifications of each reinforcement 400 after cutting are the same, the center of the dense weaving area 100 is cut, that is, each reinforcement 400 includes a section of pattern weaving area 200 and symmetrically arranged dense weaving areas 100 cut along the center line. This achieves a circular weaving method within the width when manufacturing multiple reinforcements 400, thereby improving the weaving efficiency.

[0067] With regard to the manufacturing process of the annular tensioning reinforcement, in a preferred embodiment of the present invention, the following steps are also included: weaving to form three sections of dense woven areas 100, and weaving a patterned woven area 200 between any two adjacent sections of dense woven areas 100; using the three sections of dense woven areas 100 to form a first section of dense woven area 101, a second section of dense woven area 102 and a third section of dense woven area 103; cutting at the midline of the first section of dense woven area 101 and the third section of dense woven area 103, and cutting the local glue-coated area in half; sealing the first section of dense woven area 101 and the third section of dense woven area 103 after cutting to form an annular tensioning reinforcement; wherein, one end of the annular tensioning reinforcement is the first section of dense woven area 101 and the third section of dense woven area 103 after cutting and sealing, and the other end of the annular tensioning reinforcement is the second section of dense woven area 102; weaving the dense woven area 100 and the patterned woven area 200 in sequence in an intermittent weaving manner to form a circular weaving.

[0068] In this embodiment, during the cutting process of the annular tie bar, in order to ensure the loop weaving method within the door width, the dense woven area 100 and the pattern woven area 200 are woven in sequence by using the interval weaving method, wherein the widths of any two adjacent groups of dense woven areas 100 are the same. In order to ensure that the specifications of each tie bar 400 after cutting are the same, three sections of dense woven areas 100 and one section of pattern woven area 200 are used as a stage of the door width cycle, and the three adjacent sections of dense woven areas 100 are named the first section of dense woven area 101, the second section of dense woven area 102 and the third section of dense woven area 103. The first section of dense woven area 101 and the third section of dense woven area 103 are cut based on the center of the first section of dense woven area 101 and the third section of dense woven area 103, and then the cut first section of dense woven area 101 and the third section of dense woven area 103 are aligned and edge-sealed. That is, the first section of dense woven area 101 and the third section of dense woven area 103 after cutting serve as one end of the reinforcement 400, the complete second section of dense woven area 102 serves as the other end of the reinforcement 400, and the two adjacent sections of patterned woven area 200 serve as two relatively high side walls of the annular reinforcement. After the two ends of the annular reinforcement are respectively connected with the cover cloth 500 and the base cloth 600, the two adjacent sections of patterned woven area 200 just form the high side walls of the reinforcement 400. The low weaving density can also reduce the weight of the reinforcement 400 and improve the air permeability. During cutting, the dense woven area 100 needs to be cut at intervals to ensure that the two ends of the annular reinforcement are still the width of a section of dense woven area 100, thereby realizing the circular weaving method within the door width when manufacturing multiple reinforcements 400, thereby improving the weaving efficiency.

[0069] like Figure 5-Figure 9 As shown, in a preferred embodiment of the present invention, the pattern weaving area 200 is a grid structure weaving area; or, the pattern weaving area 200 includes woven reinforcing ribs 201 and a pattern area 202, the pattern area 202 forms a hollow pattern structure, and the reinforcing ribs 201 have multiple reinforcing ribs, and the reinforcing ribs 201 are woven along the edges of the pattern area 202.

[0070] In this embodiment, there can be multiple structures of the pattern weaving area 200 between any two adjacent sections, for example: the first is to form a weaving area by a grid structure without manufacturing a pattern, and the grid can be square or diamond-shaped; the second is to form a unit pattern by weaving dense lines, and the unit array, symmetry, rotation and other patterns are arranged in an orderly or free arrangement to form a pattern, and the reinforcing ribs 201 are added in combination with the pattern according to the stress conditions; the third is that for regular patterns, each group or several groups can be directly hollowed out, and the hollowed-out edges are densely packed with weaving lines, namely, reinforcing ribs 201, and the number of groups of reinforcing ribs 201 is not less than the number of patterns; by setting the weaving of the pattern weaving area 200, by increasing the density of the weaving lines, increasing the reinforcing ribs 201 and the pattern area 202, and increasing the toughness of the tie rod 400, any shape hollowing can be performed at appropriate positions to reduce the weight and air permeability of the tie rod 400.

[0071] like Figure 1-Figure 14 As shown, a tensioning rod provided in this embodiment is manufactured by the tensioning rod manufacturing process described above; since the technical effect of the tensioning rod 400 provided in this embodiment is the same as the technical effect obtained by the tensioning rod manufacturing process provided in the above embodiment, it will not be described in detail here.

[0072] like Figure 12-14 As shown, an inflatable product provided in this embodiment includes: a cover cloth 500, a base cloth 600 and the above-mentioned tie rod 400; the tie rod 400 is located between the cover cloth 500 and the base cloth 600, and rubber coating layers are arranged at intervals along the two side surfaces of the tie rod 400, and the tie rod 400 is connected to the cover cloth 500 and the base cloth 600 respectively through the rubber coating layers on both sides through a hot melt process; a plurality of tie rods 400 are provided, and the plurality of tie rods 400 are arranged at intervals along an extension direction perpendicular to the tie rod 400.

[0073] In a preferred embodiment of the present invention, it also includes a side wall 700; the side wall 700 is arranged circumferentially along the edge of the cover cloth 500, and the side wall 700 is respectively connected to the cover cloth 500 and the base cloth 600, and an inflatable space for accommodating the tensioning rod 400 is formed between the cover cloth 500, the side wall 700 and the base cloth 600.

[0074] Optionally, since the tie rods 400 mainly play a supporting and shaping role, in order to make the inflatable product provided by this embodiment have a more stable shape and not easy to deform, a plurality of tie rods 400 can be arranged at intervals between the cover cloth 500 and the base cloth 600.

[0075] In this embodiment, the tie rod 400 is used in the application of an inflatable mattress, wherein the cover cloth 500 and the base cloth 600 can both be made of TPU coated fabric, which is environmentally friendly and wear-resistant and suitable for a variety of outdoor environments; by arranging several C-shaped tie rods or annular tie rods made by the above process between the cover cloth 500 and the base cloth 600, it is also possible to have a support of the side wall 700 in the same series, and arrange them evenly at intervals. The opposite sides of the tie rod 400 are hot-melt connected with the cover cloth 500 and the base cloth 600 through the position of local glue coating, so that the welding point of the air mattress is concave downward after inflation, while other places bulge upward, so that multiple patterns are formed on the surface of the inflatable mattress, and it also acts as a pillar, and by providing an air valve on the inflatable mattress, the technical effects of fast inflation and deflation and convenient carrying are achieved; the C-shaped tie rod or annular tie rod formed by the tie rod manufacturing process provided in the above embodiment is actually applied, and the tie rod 400 has the effect of light weight and ventilation, which ensures faster inflation and deflation and improves efficiency.
