Description

Composite fabric and punching die

Technical Field

The present invention relates to a composite fabric and a punching mold, and more particularly, to a composite fabric having an annular composite structure and a punching mold for forming the annular composite structure.

Background

In general, to protect a user, such as an athlete, from impact during athletic scrubs, prior composite fabrics have included a layer of elastic material between two structures to provide protection. However, while providing protection, the conventional composite fabric is provided with an elastic material layer, so that the ductility and the mobility of the composite fabric are reduced, and the flexibility during use is further reduced, thereby causing discomfort during use.

In view of the above, there has been developed a new composite fabric, in which through holes are punched in an elastic material layer to improve the extensibility of the composite fabric, which can improve the flexibility of the composite fabric to some extent during use, but still hinder the flexibility of the composite fabric during a wide range of stretching.

In view of the above, a composite fabric that provides protection while maintaining extensibility and mobility remains a goal of common efforts by the relevant industries.

Embodiments of the present invention will be described below with reference to the accompanying drawings. For the purposes of clarity, numerous implementation details are set forth in the following description. However, the reader should understand that these implementation details should not be used to limit the utility model. That is, in some embodiments of the utility model, these implementation details are not necessary. In addition, some conventional structures and elements are shown in the drawings in a simplified schematic manner for the sake of simplifying the drawings; and repeated elements will likely be referred to using the same reference number or similar reference numbers.

Referring to fig. 1 and 2, fig. 1 is a schematic top view of a composite fabric 100 according to a first embodiment of the present invention, and fig. 2 is a side cross-sectional view of the composite fabric 100 according to an embodiment of fig. 1. As shown in fig. 1 and 2, the composite fabric 100 includes a base fabric structure 110, a covering structure 130 and a plurality of ring-shaped composite structures 120. The base fabric structure 110 has an upper surface, and the cover structure 130 is disposed on the upper surface of the base fabric structure 110. The plurality of annular composite structures 120 are disposed between the base fabric structure 110 and the covering structure 130, and the covering structure 130 covers the annular composite structures 120. Each of the annular composite structures 120 includes an inner through hole 121 for penetrating the base fabric structure 110, the annular composite structures 120 are arranged at intervals and have a gap d between the annular composite structures 120, wherein the annular composite structures 120 may include elastic material layers.

The annular composite structure 120 provides protection against impacts by the elasticity of the elastomeric layer. Furthermore, through the structure of the inner through hole 121 and the gap d between the annular composite structures 120, a gap for movement is formed between the annular composite structures 120, and the annular composite structures 120 can provide a protection function independently without being influenced by each other, so as to avoid reducing mobility, thereby improving ductility and mobility of the composite fabric 100. Thereby, the protection of the user during use can be provided and the flexibility during use can be maintained.

Specifically, the base fabric structure 110 and the covering structure 130 may be made of mesh material, the mesh material may be elastic mesh, Polyurethane (PU) cloth, Thermoplastic Polyurethane (TPU) cloth, or leather, and the elastic material layer of the annular composite structure 120 may be made of foam material, but the utility model is not limited thereto.

Further, each annular composite structure 120 may include an inner edge 122 and an outer edge 123. The inner edge 122 defines an inner through hole 121, and the outer edge 123 is substantially polygonal, and the number of sides of the polygon is more than three. Furthermore, the shape of the inner edge 122 of each annular composite structure 120 may correspond to the shape of the outer edge 123 of each annular composite structure 120. In the first embodiment, the number of sides of the polygon is six, so that the overall shape of the annular composite structure 120 is a regular hexagonal ring. In other embodiments, the shape of the inner edge may not correspond to the shape of the outer edge, for example, the shape of the inner edge may be circular, and the shape of the outer edge may be generally hexagonal, but the utility model is not limited thereto.

As shown in fig. 1 and 2, the gap d between the annular composite structures 120 may be 0.5mm to 2.0 mm. When the gap d is too large, the protective force provided by the annular composite structure 120 is reduced; when the gap d is too small, it is difficult for the clad structure 130 to cover each of the annular composite structures 120 individually. In the first embodiment, the gap d is 1.0 mm. Thereby, the extensibility and mobility of the composite fabric 100 can be improved without reducing the protective force.

Referring to fig. 3, a schematic diagram of a plurality of endless composite structures 120a of a composite fabric according to a second embodiment of the utility model is shown. The composite fabric of the second embodiment is similar to the composite fabric 100 of the first embodiment, with the only difference being that the structure of the endless composite structure 120a is slightly different. Specifically, the outer edge of the annular composite structure 120a is a polygon having four sides, and specifically, the outer edge of the annular composite structure 120a is almost rhombic.

Referring to fig. 4, a schematic diagram of a plurality of endless composite structures 120b of a composite fabric according to a third embodiment of the utility model is shown. The composite fabric of the third embodiment is similar to the composite fabric 100 of the first embodiment, with the only difference being that the structure of the endless composite structure 120b is slightly different. Specifically, the outer edge of the annular composite structure 120b is a polygon with three sides, and specifically, the outer edge of the annular composite structure 120b is substantially in the shape of a regular triangle.

Referring to fig. 5, a schematic diagram of a plurality of endless composite structures 120c of a composite fabric according to a fourth embodiment of the utility model is shown. The composite fabric of the fourth embodiment is similar to the composite fabric 100 of the first embodiment, with the only difference being that the structure of the endless composite structure 120c is slightly different. Specifically, the outer edge of the annular composite structure 120c is a polygon having six sides, and specifically, the outer edge of the annular composite structure 120c is a hexagon, and the sides of the hexagon opposite to each other are longer than the sides of the other four sides.

Referring to fig. 6, a schematic diagram of a plurality of annular composite structures 121d,122d of a composite fabric according to a fifth embodiment of the utility model is shown. The composite fabric of the fifth embodiment is similar to the composite fabric 100 of the first embodiment, with the only difference being that the structure of the endless composite structures 121d,122d is slightly different. Specifically, the outer edges of the annular composite structures 121d and 122d are polygonal with four sides, the outer edge of the annular composite structure 121d is substantially parallelogram-shaped, and the outer edge of the annular composite structure 122d is substantially rectangular. The annular composite structures 121d are arranged on two sides of the annular composite structure 122d, and form an angle therebetween, so that the annular composite structures 121d and the annular composite structure 122d are arranged in a wave shape.

Referring to fig. 7, a schematic diagram of a plurality of endless composite structures 121e,122e,123e of a composite fabric according to a sixth embodiment of the utility model is shown. The composite fabric of the sixth embodiment is similar to the composite fabric 100 of the first embodiment, with the only difference being that the endless composite structures 121e,122e,123e have slightly different structures. More specifically, the outer edges of the annular composite structures 121e and 122e are polygons with four sides, the outer edge of the annular composite structure 123e is a polygon with three sides, the outer edge of the annular composite structure 121e is substantially square, the outer edge of the annular composite structure 122e is substantially diamond-shaped, the outer edge of the annular composite structure 123e is substantially regular triangle-shaped, and the annular composite structures 121e,122e, and 123e are arranged in the geometric shape shown in fig. 7. In other words, the size and shape of the annular composite structures 121e,122e,123e are different for the same composite fabric, so as to provide visual variation and adjustment of strength, but the utility model is not limited thereto.

Referring to fig. 8, a schematic view of a plurality of endless composite structures 121f,122f,123f of a composite fabric according to a seventh embodiment of the utility model is shown. The composite fabric of the seventh embodiment is similar to the composite fabric 100 of the first embodiment, with the only difference being that the endless composite structures 121f,122f,123f have slightly different structures. Specifically, the outer edge of the annular composite structure 121f is a polygon with five sides, the outer edges of the annular composite structures 122f and 123f are polygons with four sides, the outer edge of the annular composite structure 121f is substantially a regular pentagon, the outer edge of the annular composite structure 122f is substantially a rhombus, and the outer edge of the annular composite structure 123f is substantially a rhombus with another different size. The annular composite structures 121f,122f,123f are arranged as in the geometry of fig. 8.

Referring to fig. 9, a schematic diagram of a punching mold 200 and a composite substrate 300 according to an eighth embodiment of the utility model is shown. The punching mold 200 is used for punching a plurality of annular composite structures on the composite substrate 300, and includes a first substrate 210, a plurality of inner edge cutters 220, a plurality of outer edge cutters 230, and a second substrate 240. It should be noted that the annular composite structure punched out of the composite substrate 300 may be the annular composite structure 120 of the first embodiment, which will be described below in conjunction with the annular composite structure 120 of the first embodiment in fig. 1 and 2. The inner edge cutters 220 are disposed below the first substrate 210, each inner edge cutter 220 is annular, and the inner edge cutters 220 are used for punching an inner through hole 121 of each annular composite structure 120 on the composite substrate 300. The outer edge cutters 230 are movably disposed on the first substrate 210, each outer edge cutter 230 is annular and located outside each inner edge cutter 220, and a diameter of each outer edge cutter 230 is greater than a diameter of each inner edge cutter 220. The second substrate 240 is disposed on the first substrate 210 and is used for pressing the outer edge cutter 230.

Through the configuration of the inner edge cutter 220 and the outer edge cutter 230, the first substrate 210 drives the inner edge cutter 220 to punch the composite substrate 300 downward and punch the inner through hole 121 of the annular composite structure 120, then the second substrate 240 moves downward and can press the outer edge cutter 230 to punch the composite substrate 300 for a second time, and the outer edge cutter 230 cuts the outer edge 123 of the annular composite structure 120. Therefore, the actions of punching (punching the inner through hole 121) and cutting (cutting the independent annular composite structures 120) can be simultaneously completed in a single die, so that the problem that the conventional punching die cannot perform secondary processing is solved, and the composite fabric which can provide protection, has ductility and mobility can be manufactured subsequently.

Specifically, the cut-out die 200 may further include a discharge structure 250. The discharge structure 250 is disposed between the first substrate 210 and the second substrate 240 and connected to the first substrate 210. When the second substrate 240 moves downward, the discharging structure 250 is pressed to drive the first substrate 210 and the inner edge cutter 220 to move downward to discharge the waste materials punched out from the composite substrate 300. Therefore, the smoothness of punching and waste stripping can be improved.

Further, each of the outer edge cutters 230 may include a blade 231, an abutting portion 232, and a damping element 233. The blade 231 penetrates the first substrate 210. The abutting portion 232 is connected to the blade 231 and located above the first substrate 210. The damping element 233 abuts against the abutting portion 232 and the first substrate 210, wherein the second substrate 240 abuts against the abutting portion 232 after being pressed down. Therefore, when the first substrate 210 moves down to punch the composite substrate 300 by the inner edge cutter 220, the blade 231 of the outer edge cutter 230 is pushed and moved upwards when abutting against the composite substrate 300, which may be a part of the composite substrate 300 which is not punched or only punched, and the first substrate 210 is still limited by the damping element 233, then the second substrate 240 presses down against the abutting part 232 to drive the outer edge cutter 230 to punch, and the speed of pressing down the second substrate 240 is buffered by the damping element 233, so that the phenomenon that when the second substrate 240 presses down to perform secondary punching, the cutting force of the outer edge cutter 230 is too large, which results in punching of the composite substrate 300, further damages the overall structure of the annular composite structure 120, and reduces the production yield is avoided. Thereby, the cutting stability of the outer edge cutter 230 can be improved.

As shown in fig. 9, an anti-impact height h may be formed between a cutting tip of each outer edge cutter 230 and a cutting tip of each inner edge cutter 220, and the anti-impact height h is 0.1mm to 2.0 mm. Furthermore, the composite substrate 300 may include an elastic material layer 310, an adhesive layer 320, and a cutting stress layer 330. The elastomeric layer 310 is adjacent to the die cut mold 200, the cutting stressed layer 330 is remote from the die cut mold 200, and the adhesive layer 320 is disposed between the elastomeric layer 310 and the cutting stressed layer 330. Specifically, the anti-punching height h may be the thickness of the cutting stress layer 330 plus a portion of the thickness of the adhesive layer 320, such that the inner edge cutter 220 can punch through the composite substrate 300 to punch out the inner through hole 121, while the outer edge cutter 230 punches through the adhesive layer 320 without punching through the adhesive layer 320 and the cutting stress layer 330 (about 30% to 70% of the thickness of the adhesive layer 320). In the eighth embodiment, the anti-impact height h is 0.5mm, the elastic material layer 310 may be die-cut to form the annular composite structure 120, and the adhesive layer 320 and the cutting stress layer 330 are made of materials with different densities and different thicknesses, respectively. The cutting stress layer 330 can be used to buffer and stabilize the cutting force, and prevent the outer edge cutter 230 from breaking through the adhesive layer 320.

Moreover, the outer edge cutters 230 and the inner edge cutters 220 can be used to cut the annular composite structures 120a,120b,120c,121d,122d,121e,122e,123e,121f,122f,123f according to the second to seventh embodiments, which should not be construed as a limitation to the utility model.

Referring to fig. 10, a block flow diagram of a method S100 for manufacturing a composite fabric according to a ninth embodiment of the utility model is shown. In the ninth embodiment, the composite fabric 100 of the first embodiment and the punching mold 200 of the eighth embodiment are used together for description, but the utility model is not limited thereto. The composite fabric manufacturing method S100 includes an endless composite structure cutting step S110. In the step S110 of cutting the annular composite structure, a punching mold 200 is taken to cut a composite substrate 300 to form a plurality of annular composite structures 120, a first stage punching is performed, a plurality of inner edge cutters 220 of the punching mold 200 are pressed down to form a plurality of inner through holes 121 of the annular composite structure 120, a second stage punching is performed, a plurality of outer edge cutters 230 of the punching mold 200 are pressed down to form a plurality of annular gaps d to separate the annular composite structures 120.

Therefore, the actions of punching and cutting can be completed simultaneously in a single process, the problem that secondary processing cannot be performed in the prior punching technology is solved, and the composite fabric 100 which can provide protection, has extensibility and mobility can be manufactured subsequently.

Specifically, the composite substrate 300 may include the elastic material layer 310, the adhesive layer 320 and the cutting force-bearing layer 330 according to the eighth embodiment, which are not described in detail herein. When the second punching is performed in the annular composite structure cutting step S110, the outer edge cutter 230 does not punch the cutting stress layer 330. The punched annular composite structures 120 may remain joined by the cut stress layer 330, thereby facilitating subsequent processing after punching.

The composite fabric manufacturing method S100 may further include a combining step S120. In the combining step S120, the annular composite structure 120 is combined with a base fabric structure 110 and a covering structure 130, so that the annular composite structure 120 is located between the base fabric structure 110 and the covering structure 130, thereby completing a composite fabric 100. Specifically, glue is applied to the base fabric structure 110, one side with the glue is covered on the punched composite substrate 300, and the side of the elastic material layer 310 away from the adhesive layer 320 is bonded to the base fabric structure 110, and then the cutting stress layer 330 connecting the annular composite structures 120 is removed, and the adhesive layer 320 punched into the annular composite structures 120 is adhered to the covering structure 130, so as to complete the composite fabric 100.

In summary, the present invention provides a method for manufacturing a composite fabric, a composite fabric and a punching mold, which have the following advantages: firstly, through the configuration of an inner edge cutter and an outer edge cutter of a punching die, the processes of punching and cutting can be simultaneously carried out; and secondly, the ductility and the mobility of the composite fabric can be improved while protection is provided through gaps of the annular composite structures.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the utility model.
