Description

Technical Field

[0001] The present invention relates to the field of fabric composites, and in particular to a composite device for multi-layer fabrics and a composite method for wear-resistant fabrics. Background Art

[0002] A fabric composite device is a special equipment used to tightly combine two or more fabrics of different materials through bonding, hot pressing or other physical and chemical methods. It is widely used in textiles, clothing, home furnishings, automotive interiors, medical protection and other fields. Its main function is to give the fabric new properties or optimize the original properties through the composite process. The core working principle of the fabric composite device usually includes feeding, gluing, composite, drying, cooling, winding and other links. According to different process requirements, the device may be equipped with key components such as hot melt adhesive coating system, pressure roller device, temperature control system, tension adjustment system, etc. The composite fabric may have the characteristics of waterproof and breathable, antibacterial and flame retardant, enhanced wear resistance, improved elasticity or appearance texture.

[0003] Chinese patent application CN107599591A discloses a composite part winding structure in a hot pressing composite system. The composite part winding structure is arranged on a blanking support frame in a blanking subsystem of the hot pressing composite system, and includes a reel for rolling the composite part in the hot pressing composite system into a cylindrical shape. The characteristics are as follows: the reel is movably arranged on a composite part winding transmission assembly that drives the reel to roll, and the two ends of the composite part winding transmission assembly are respectively arranged on two lateral sides of the blanking support frame. The reel is movably arranged on two composite part winding transmission rollers responsible for carrying and transmitting the composite part, which facilitates the reel to quickly roll the composite part, and the radial size of the cylindrical structure rolled by the composite part is not restricted;

[0004] Chinese patent CN115534484B discloses a hot pressing device for clothing fabrics, including a support frame and a fabric composite module, a fabric correction module, a gluing module, a hot pressing module and a dust removal module arranged in sequence on the support frame along the fabric transmission direction, wherein the fabric composite module includes a grey cloth storage shaft for storing and rolling up the grey cloth, a limiting shaft for longitudinally separating the grey cloth and a stacking shaft for stacking the grey cloth in layers and forming a composite fabric, which are arranged in sequence on the support frame along the fabric transmission direction. The grey cloth storage shaft, the limiting shaft and the stacking shaft are all provided in several groups. By providing the fabric correction module, the stacked layers of clothing fabrics are aligned and leveled, thereby solving the technical problem of inaccurate alignment of the upper and lower layers of fabrics due to the superposition and compounding of multiple layers of fabrics, achieving the effect of correcting the position of the fabric and enhancing the quality of the hot pressing molding of the fabric.

[0005] The above patents and prior art also have the following defects:

[0006] When the existing fabric composite equipment is winding the fabric, it is unable to press the wound fabric tightly, causing the fabric to easily deviate and become loose during the winding process. After the fabric is wound again, the winding roller needs to be replaced. The replacement operation has many steps and is relatively troublesome, resulting in long downtime. The end of the replaced fabric cannot be fixed, causing the end of the fabric to easily unwind during the subsequent conveying process, resulting in loose fabric rolls. In subsequent processing, the loose fabric has poor discharge accuracy, affecting the processing effect.

DETAILED DESCRIPTION

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0047] Example 1: Reference Figures 1-13 The multi-layer fabric composite device shown includes a frame 1, a plurality of unwinding rollers 2 are provided on the frame 1, the unwinding rollers 2 are rotatably connected to the frame 1, and two hot pressing rollers 3 are rotatably connected to the frame 1. A winding assembly 4 is provided on one side of the frame 1, and the fabrics on the plurality of unwinding rollers 2 are connected to the winding assembly 4 via the hot pressing rollers 3;

[0048] The winding assembly 4 includes a switching frame 418 and several group winding units. The switching frame 418 can rotate the several winding units to the winding position in sequence. The winding unit includes a winding roller 401 and a pressure plate 402. The pressure plate 402 can move as the diameter of the cloth on the winding roller 401 increases. When the diameter of the cloth on the winding roller 401 reaches the maximum value, the pressure plate 402 is fixed and keeps the cloth pressed.

[0049] Multiple fabrics are unwound by the unwinding roller 2, and the fabrics are introduced between the two hot pressing rollers 3 through multiple finishing rollers. Before that, glue is coated between the multiple fabrics, and the two hot pressing rollers 3 press and bond the fabrics. The fabrics that have been hot-pressed are wound up by the winding roller 401. During the winding process of the winding roller 401, the pressing plate 402 presses the fabric on the winding roller 401, and the pressing plate 402 moves as the diameter of the fabric on the winding roller 401 increases. When the diameter of the fabric on the winding roller 401 reaches the maximum value, the pressing plate 402 is fixed, and the pressing plate 402 keeps pressing the fabric. The switching frame 418 drives several winding units to move, so that the winding unit that has completed the fabric winding is removed from the winding position for disassembly, and the next winding unit moves to the winding position for winding.

[0050] During the process of winding the fabric, the fabric is continuously pressed by the pressing plate 402 to prevent the fabric from being loose or slipping. After the fabric is wound to its maximum diameter, the pressing plate 402 is fixed to ensure that the fabric roll is tight and prevent the fabric roll from loosening due to unwinding during transportation. The switching frame 418 drives the switching of multiple winding units, so that the winding unit that has completed winding can quickly leave the winding position for disassembly, and the new winding unit can quickly move to the winding position for winding, which greatly reduces the downtime caused by replacing the winding roller 401 and improves continuous production efficiency.

[0051] Example 2, reference Figures 1-13 As shown, the difference from the above embodiment is that the winding unit also includes a protective side plate 403, a rotating roller 404, a pressure block 405, a moving block 406, a fixed screw 407, a fixed gear 408 and a driving rack 409, the protective side plate 403 is rotatably connected to the winding roller 401, the rotating roller 404 is rotatably connected to the pressure plate 402, the pressure plate 402 can move on the protective side plate 403, the pressure block 405 is arranged on the pressure plate 402, the fixed screw 407 is rotatably connected to the pressure plate 402, the moving block 406 is fixedly installed on the pressure block 405, the moving block 406 is sleeved on the fixed screw 407 and is threadedly connected to the fixed screw 407, the fixed gear 408 is fixedly installed on the fixed screw 407, and the winding component 4 also includes a driving rack 409. When the cloth diameter on the winding roller 401 reaches the maximum value, the fixed gear 408 moves to engage with the driving rack 409.

[0052] The rotating roller 404 is in abutment with the fabric on the winding roller 401. When the winding roller 401 winds the fabric, the rotating roller 404 rotates and does not block the winding of the fabric. At the same time, the increasing diameter of the fabric pushes the rotating roller 404 and the pressing plate 402 to move. The pressing plate 402 drives the pressing block 405, the moving block 406, the fixed screw rod 407, and the fixed gear 408 to move. When the diameter of the fabric on the winding roller 401 reaches the maximum value, the fixed gear 408 moves to mesh with the driving rack 409. Then, the protective side plate 403, the winding roller 401, and the pressing plate 402 move circumferentially under the driving of the switching frame 418. The fixed gear 408 rotates on the driving rack 409 while rotating. The fixed gear 408 drives the fixed screw rod 407 to rotate. The moving block 406 moves on the fixed screw rod 407. The moving block 406 drives the pressing block 405 to move. The pressing block 405 moves and abuts against the fabric to press the fabric on the winding roller 401.

One end of the pressing spring 412 is fixedly installed on the connecting block 410. The pressing spring 412 is sleeved on the connecting rod 411.

[0054] When the pressing plate 402 moves, the connecting block 410 moves in the connecting strip hole. The pressing spring 412 presses the pressing plate 402 against the fabric through the connecting block 410 to press the fabric.

[0055] Embodiment 4, refer to Figures 1-13 As shown in the figure, different from the above embodiments, the winding assembly 4 further comprises a fixed rod 413 and a fixed frame 414.

A rectangular groove is provided at the end of the winding roller 401, the limit block 61 is rectangular, the quick release rod 62 is fixedly installed on the limit block 61, and an anti-twist plate is provided on the quick release rod 62, and the anti-twist plate is rotatably connected to the quick release rod 62. One end of the quick release spring 64 is fixedly installed Installed on the anti-twist plate, the other end of the quick-release spring 64 is fixedly mounted on the switching frame 418, the quick-release rod 62 passes through the switching frame 418 and slides with the switching frame 418, the quick-release spring 64 is sleeved on the quick-release rod 62, the quick-release gear 63 is fixedly mounted on the quick-release rod 62, the quick-release handle is fixedly mounted on the quick-release gear 63, and a rotating assembly 7 is provided on the fixed frame 414. When the winding assembly 4 rotates to the winding position, the rotating assembly 7 can drive the corresponding quick-release gear 63 to rotate.

[0058] When it is necessary to disassemble the winding unit that has been wound, pull the quick-release handle, which drives the quick-release gear 63 to move, and the quick-release gear 63 drives the quick-release rod 62 to move, and the quick-release rod 62 drives the limit block 61 to move, and the limit block 61 disengages from the rectangular groove on the winding roller 401, and the winding unit is disassembled accordingly. Conversely, the new winding unit is installed on the switching frame 418, which can quickly disassemble and install the winding unit, with fewer operating steps, more convenience, and reduced time for disassembling and installing the winding unit.

[0059] Example 6, reference Figures 1-13 As shown, the difference from the above embodiment is that the rotating assembly 7 includes a rotating motor 71, a rotating gear 72 and a rotating belt member 73, the rotating motor 71 is fixedly mounted on the fixed frame 414, the rotating gear 72 is fixedly mounted on the rotating shaft, the rotating shaft is rotatably connected to the fixed frame 414, the rotating belt member 73 includes a rotating active pulley, a rotating passive pulley and a rotating belt, the rotating active pulley is fixedly mounted on the output end of the rotating motor 71, the rotating passive pulley is fixedly mounted on the rotating shaft, and the rotating belt is connected to the rotating active pulley and the rotating passive pulley.

[0060] When the corresponding winding unit rotates to the winding position, the quick-release gear 63 engages with the rotating gear 72, the rotating motor 71 drives the rotating active pulley to rotate, the rotating active pulley drives the rotating belt to rotate, the rotating belt causes the rotating passive pulley to rotate, the rotating passive pulley drives the rotating gear 72 to rotate, the rotating gear 72 drives the quick-release gear 63 to rotate, the quick-release gear 63 drives the quick-release lever 62 to rotate, the quick-release lever 62 drives the limit block 61 to rotate, the limit block 61 drives the winding roller 401 to rotate, and the winding roller 401 winds up the fabric, ensuring that the winding unit can be quickly disassembled. Under the premise that each winding unit that moves to the winding position can wind up the fabric, it is more convenient to use and increases the adaptability of the equipment.

[0061] Example 7, reference Figures 1-13 As shown, the difference from the above embodiment is that the winding unit also includes a driving bevel gear 415, a passive bevel gear 416 and a transmission rod 417, the passive bevel gear 416 is fixedly mounted on the fixed screw 407, the driving bevel gear 415 is fixedly mounted on the transmission rod 417, the passive bevel gear 416 is meshed with the driving bevel gear 415, the transmission rod 417 is rotatably connected to the clamping plate 402, and the fixed gear 408 is fixedly mounted on the transmission rod 417.

[0062] When the winding unit that has completed winding moves to, the fixed gear 408 rotates while moving on the driving rack 409, the fixed gear 408 drives the transmission rod 417 to rotate, the transmission rod 417 drives the active bevel gear 415 to rotate, the active bevel gear 415 drives the passive bevel gear 416 to rotate, and the passive bevel gear 416 drives the fixed screw 407 to rotate, thereby moving the pressing block 405.

When the winding unit is moved from the winding position after the winding is completed, the winding unit is located at the bottom of the switching frame 418, and the notch of the supporting groove is downward, so that the supporting block 9 can quickly detach from the supporting groove. At the same time, the supporting block 9 prevents the protective side plate 403 from rotating during the process of winding the fabric, so that the fixed gear 408 corresponds to the drive rack 409.

[0065] A rubber block is fixedly mounted on one end of the pressing block 405 , and the rubber block is arranged in an arc shape.

[0066] The pressing block 405 is made to fit more closely to the fabric, thereby increasing the friction between the pressing block 405 and the fabric, and achieving a better pressing effect on the fabric.
