Detailed Description
Embodiments of the present invention will be described below with reference to the accompanying drawings. For purposes of clarity, many practical details will be set forth in the following description. However, the reader should appreciate that these practical details should not be used to limit the invention. That is, in some embodiments of the invention, these practical details are unnecessary. Furthermore, for the sake of simplicity of the drawing, some of the existing conventional structures and elements are shown in the drawing in a simplified schematic manner; and repeated elements will likely be indicated by identical or analogous numerals.
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 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 comprises a base fabric structure 110, a cover structure 130, and a plurality of endless 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 cladding structure 130, and the cladding structure 130 covers the annular composite structures 120. Each of the annular composite structures 120 includes an inner through hole 121 for viewing the base fabric structure 110, the annular composite structures 120 are spaced apart with a gap d between the annular composite structures 120, wherein the annular composite structures 120 may include an elastomeric layer.
The annular composite structure 120 can provide a protective force upon impact buffering by the elasticity of the elastic material layer. Furthermore, the inner through holes 121 and the gaps d between the annular composite structures 120 enable gaps for movement between the annular composite structures 120, and the annular composite structures 120 can independently provide protection functions without being affected by each other, so that mobility is prevented from being reduced, and ductility and mobility of the composite fabric 100 are improved. Therefore, the protection of a user in use can be provided, and meanwhile, the flexibility in use is maintained.
Specifically, the base fabric structure 110 and the covering structure 130 may be made of a mesh material, which may be an elastic mesh, polyurethane (PU) cloth, thermoplastic polyurethane (Thermoplastic Poly Urethanes; TPU) cloth or leather, and the elastic material layer of the annular composite structure 120 may be made of a foaming material, but the invention 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, the outer edge 123 is a polygon, 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 approximately 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 hexagonal, but the invention is not limited thereto.
As shown in fig. 1 and 2, the gap d between the annular composite structures 120 may be 0.5mm-2.0mm. When the gap d is too large, the protection force provided by the annular composite structure 120 is reduced; when the gap d is too small, it is difficult for the cladding structure 130 to individually cover each annular composite structure 120. In the first embodiment, the gap d is 1.0mm. 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 invention is shown. The composite fabric of the second embodiment is similar to the composite fabric 100 of the first embodiment, with only a slight difference in the structure of the endless composite structure 120 a.

Specifically, the outer edge of the annular composite structure 120c has a polygonal shape with six sides, specifically, the outer edge of the annular composite structure 120c has a hexagonal shape, and the length of the sides of the hexagon opposite to each other is greater than that of the other four sides.
Referring to fig. 6, a schematic diagram of a plurality of endless composite structures 121d,122d of a composite fabric according to a fifth embodiment of the invention is shown. The composite fabric of the fifth embodiment is similar to the composite fabric 100 of the first embodiment, with only slight differences in the construction of the endless composite structures 121d,122 d.

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 invention is shown. The composite fabric of the sixth embodiment is similar to the composite fabric 100 of the first embodiment, with only slight differences in the construction of the endless composite structures 121e,122e,123 e. In detail, the outer edges of the annular composite structures 121e and 122e are polygonal with four sides, the outer edge of the annular composite structure 123e is polygonal with three sides, the outer edge of the annular composite structure 121e is approximately square, the outer edge of the annular composite structure 122e is approximately diamond-shaped, the outer edge of the annular composite structure 123e is approximately regular triangle, and the annular composite structures 121e,122e and 123e are arranged in the geometric shape shown in fig. 7. In other words, the annular composite structures 121e,122e,123e are different in size and shape for the same composite fabric, and can provide visual variation and adjustment of strength, but the invention is not limited thereto.
Referring to fig. 8, a schematic diagram of a plurality of endless composite structures 121f,122f,123f of a composite fabric according to a seventh embodiment of the invention is shown. The composite fabric of the seventh embodiment is similar to the composite fabric 100 of the first embodiment, with only slight differences in the structure of the endless composite structures 121f,122f,123 f. Specifically, the outer edge of the annular composite structure 121f has a polygonal shape with five sides, the outer edges of the annular composite structures 122f and 123f have a polygonal shape with four sides, the outer edge of the annular composite structure 121f has a substantially regular pentagon shape, the outer edge of the annular composite structure 122f has a substantially diamond shape, and the outer edge of the annular composite structure 123f has a substantially diamond shape with another different size. The annular composite structures 121f,122f,123f are arranged in the geometry of fig. 8.
Referring to fig. 9, a schematic diagram of a punching die 200 and a composite substrate 300 according to an eighth embodiment of the invention is shown. The punching die 200 is used for punching a plurality of annular composite structures on the composite substrate 300, and comprises 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, and the annular composite structure 120 of the first embodiment of fig. 1 and 2 will be described below. The inner edge cutters 220 are disposed below the first substrate 210, and each inner edge cutter 220 is annular, and the inner edge cutter 220 is 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 is located at an outer side of each inner edge cutter 220, and a caliber of each outer edge cutter 230 is larger than a caliber of each inner edge cutter 220. The second substrate 240 is disposed on the first substrate 210 and is used to press against the outer edge cutter 230.
Through the arrangement 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 downwards, and the inner through hole 121 of the annular composite structure 120 is punched, then the second substrate 240 moves downwards and can press against the outer edge cutter 230 to punch the composite substrate 300 for the second time, and the outer edge cutter 230 cuts the outer edge 123 of the annular composite structure 120. Therefore, the punching (punching the inner through holes 121) and the cutting (cutting the annular composite structures 120 independent of each other) can be simultaneously completed in a single die, thereby overcoming the problem that the conventional punching die cannot perform secondary processing, and being capable of subsequently manufacturing a composite fabric which can provide protection and has ductility and mobility.
Specifically, the piercing die 200 may further comprise a row of material structures 250. The discharging 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 second substrate 240 presses against the discharging structure 250, and drives the first substrate 210 and the inner edge cutter 220 to move downward again to discharge the waste punched by the composite substrate 300. Therefore, the smoothness of punching and stripping waste can be improved.
Further, each peripheral cutter 230 may include a cutter body 231, a supporting portion 232 and a damping element 233. The blade 231 penetrates the first substrate 210. The abutment 232 is connected to the blade 231 and is 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 make the inner edge cutter 220 die-cut the composite substrate 300, the cutter body 231 of the outer edge cutter 230 is pushed back to move upwards when abutting against the composite substrate 300, which may be the non-die-cut composite substrate 300 or only a part of the die-cut composite substrate 300, and the first substrate 210 is still limited by the damping element 233, then the second substrate 240 is pressed down against the top 232 to drive the outer edge cutter 230 to die-cut, and the speed of pressing down the second substrate 240 is buffered by the damping element 233, so that the excessive cutting force of the outer edge cutter 230 can be avoided when the second substrate 240 is pressed down to die-cut for the second time, thereby breaking the composite substrate 300 and further destroying the integral structure of the annular composite structure 120, and reducing the production yield. Thereby, the stability of the outer edge cutter 230 during cutting can be improved.
As shown in fig. 9, a breaking-proof height h may be provided between a tip of each outer edge cutter 230 and a tip of each inner edge cutter 220, and the breaking-proof height h may be 0.1mm-2.0mm. Furthermore, the composite substrate 300 may comprise an elastic material layer 310, an adhesive layer 320 and a cutting stress layer 330. The elastic material layer 310 is adjacent to the punching die 200, the cutting force layer 330 is far away from the punching die 200, and the adhesive layer 320 is disposed between the elastic material layer 310 and the cutting force layer 330. Specifically, the anti-punching height h may be the thickness of the stress layer 330 plus a portion of the thickness of the adhesive layer 320, such that the inner edge cutter 220 can punch the composite substrate 300 to punch the inner through holes 121, and the outer edge cutter 230 punches the adhesive layer 320 without punching the adhesive layer 320 and the stress layer 330 (about 30% to 70% of the thickness of the adhesive layer 320). In the eighth embodiment, the anti-burst height h is 0.5mm, the elastic material layer 310 can 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 force layer 330 can be used to buffer and stabilize the cutting force, so as to prevent the outer edge cutter 230 from breaking the adhesive layer 320.
Furthermore, each outer edge cutter 230 and each inner edge cutter 220 may be punched to form the annular composite structures 120a,120b,120c,121d,122d,121e,122e,123e,121f,122f,123f according to the second embodiment to the seventh embodiment, which is not limited to the present invention.
Referring to fig. 10, a block flow chart of a method S100 for manufacturing a composite fabric according to a ninth embodiment of the invention is shown. In the ninth embodiment, the punching die 200 of the eighth embodiment and the composite fabric 100 of the first embodiment will be described together, but the present invention is not limited thereto. The composite fabric manufacturing method S100 includes an endless composite structure cutting step S110. In the annular composite structure cutting step S110, a die-cutting die 200 is used to cut a composite substrate 300 to form a plurality of annular composite structures 120, a first section of die-cutting is performed, a plurality of inner edge cutting blades 220 of the die-cutting die 200 are pressed down to form a plurality of inner through holes 121 of the annular composite structures 120, a second section of die-cutting is performed, and a plurality of outer edge cutting blades 230 of the die-cutting die 200 are pressed down to form a plurality of annular gaps d to separate the annular composite structures 120.
Therefore, the punching and cutting actions can be completed simultaneously in a single process, thereby overcoming the problem that the conventional punching technology cannot carry out secondary processing, and the composite fabric 100 which can provide protection and has extensibility and mobility can be manufactured later.
Specifically, the composite substrate 300 may include the elastic material layer 310, the adhesive layer 320 and the cutting stress layer 330 according to the eighth embodiment, which are not described herein. During the second stage punching in the annular composite structure cutting step S110, the outer edge cutter 230 does not punch the cutting stress layer 330. The annular composite structures 120 formed by punching may remain connected by the stress layer 330, thereby facilitating subsequent processing after punching.
The method S100 for manufacturing a composite fabric may further include a bonding step S120. In the bonding step S120, the endless composite structure 120 is bonded to a base fabric structure 110 and a cover structure 130 such that the endless composite structure 120 is positioned between the base fabric structure 110 and the cover structure 130 to complete a composite fabric 100. In detail, the base fabric structure 110 is glued, one side with glue is covered on the punched composite substrate 300, the side of the elastic material layer 310 far from the adhesive layer 320 is combined with the base fabric structure 110, 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 coating structure 130, so as to complete the composite fabric 100.
In summary, the present invention provides a method for manufacturing a composite fabric, and a punching die, which have the following advantages: firstly, the working procedures of punching and cutting can be simultaneously carried out through the arrangement of the inner edge cutting knife and the outer edge cutting knife of the punching die; and secondly, the ductility and mobility of the composite fabric can be improved while the protection is provided through the gaps of the annular composite structures.
Although the present invention has been described with reference to the above embodiments, it should be understood that the present invention is not limited thereto, and that various changes and modifications can be made by one skilled in the art without departing from the spirit and scope of the present invention as defined by the appended claims.
