Description

Technical Field

[0001] This application relates to the field of hot-pressing textile technology, and in particular to a high-toughness and wear-resistant polyester fabric and a hot-pressing device. Background Technology

[0002] Polyester fabrics are widely used in clothing, home furnishings, and industrial fields due to their excellent strength, abrasion resistance, and ease of processing. While traditional polyester fabrics possess a certain degree of abrasion resistance, they are prone to breakage and wear under high-intensity friction or complex environments, limiting their application in high-end sectors. Currently, a common method in the industry to improve the abrasion resistance of textiles is to attach an abrasion-resistant layer to the surface of the base fabric using an adhesive, and then reinforce the bond between the base fabric and the abrasion-resistant layer through a hot-pressing process.

[0003] In the process of developing this application, it was found that the technology has at least the following problems: before hot pressing the fabric, the fabric needs to be flattened, otherwise the fabric is prone to wrinkles during the hot pressing process. Manual flattening is prone to poor flattening effect, which affects product quality. Utility Model Content

[0004] In order to minimize wrinkles on the fabric surface during hot pressing and improve the hot pressing effect, this application provides a high-toughness and wear-resistant polyester fabric and a hot pressing device.

[0005] The hot pressing device provided in this application adopts the following technical solution: A hot pressing device includes several legs, all of which are fixedly mounted on a support platform. A bracket is fixedly mounted on the support platform, and a cylinder is fixedly mounted on the bracket. The output end of the cylinder faces downwards and is fixedly mounted on a hot pressing plate. Slide grooves are formed at the four corners of the support platform along diagonal directions, and sliders are slidably mounted within these grooves, with the tops of the sliders extending out of the grooves. A pressure plate is fixedly mounted on the support platform, located directly below the hot pressing plate. A clearance groove is formed on the end wall of each slider near the center of the support platform, allowing the pressure plate to extend into it. A driving assembly is provided at the bottom of the support platform, used to synchronously drive all sliders closer to or further apart and to fix the position of the sliders. A clamping assembly is provided at the end of each slider near the center of the support platform, used to clamp fabric.

[0006] By adopting the above technical solution, when hot pressing the fabric, the fabric is first placed on the pressure plate, and the four corners of the fabric are clamped by the clamping assembly. Then, the driving assembly drives the slider to slide in the groove, so that the sliders move away from each other, thereby tightening and flattening the fabric. When hot pressing the fabric, the hot pressing plate presses against the pressure plate to hot press the fabric on the pressure plate. The pressure plate is set to provide support for the hot pressing of the fabric and prevent the fabric from directly contacting the support plate with the groove, so that the groove will leave an imprint on the fabric. In this way, wrinkles on the fabric surface are avoided as much as possible, and the hot pressing forming effect is improved.

[0007] Preferably, the driving assembly includes a sliding frame, a sliding ring, connecting rods, and a power component. The sliding frame is fixed to the bottom of the support platform. The sliding ring slides vertically with the sliding frame. Four connecting rods are evenly spaced around the circumference of the sliding ring. Each connecting rod corresponds to a slider. One end of each connecting rod is hinged to the bottom of the slider, and the other end is hinged to the sliding ring. The power component is used to drive the sliding ring to slide.

[0008] By adopting the above technical solution, the power component drives the sliding ring to slide vertically on the sliding frame. Since the connecting rod is hinged to the slider and the sliding ring respectively, when the sliding ring moves vertically downward, the sliding ring pulls the slider closer to the center of the support platform through the connecting rod; when the sliding ring moves vertically upward, the sliding ring pushes the slider away from the center of the support platform through the connecting rod. In this way, all sliders move synchronously and realize the sliders moving closer or further away from each other.

[0009] Preferably, the power component includes a motor and a lead screw. The motor is fixed to the bottom of the support platform, the lead screw is coaxially fixed to the drive shaft of the motor, and the sliding ring is sleeved on the lead screw and engaged with the lead screw thread.

[0010] By adopting the above technical solution, the motor drives the lead screw to rotate. Since the sliding ring is threadedly engaged with the lead screw, the rotation of the lead screw is converted into the vertical movement of the sliding ring. The forward and reverse rotation of the motor can control the up and down movement of the sliding ring, thereby controlling the position of the slider. Moreover, the threaded engagement between the lead screw and the sliding ring has self-locking properties, ensuring that the position of the sliding ring is fixed, so as to further fix the position of the slider.

[0011] Preferably, the clamping assembly includes a fixed clamping plate, a deflection clamping plate, a rotating platform, and a protrusion. The fixed clamping plate is fixedly connected to the slider. The deflection clamping plate is located above the fixed clamping plate and is rotatably connected to the fixed clamping plate. The rotation axis of the deflection clamping plate is horizontal. The rotating platform is rotatably connected to the fixed clamping plate, and the rotation axis of the rotating platform is vertical. The protrusion is integrally formed at the bottom of the rotating platform and can abut against the top of the deflection clamping plate.

[0012] By adopting the above technical solution, when it is necessary to clamp the fabric, the corner of the fabric is placed between the fixed clamping plate and the deflecting clamping plate. Then, the rotary table is rotated so that the protrusion abuts against the top of the deflecting clamping plate. The protrusion presses down on the deflecting clamping plate, causing the deflecting clamping plate to deflect around its rotation axis towards the fixed clamping plate, thereby clamping the fabric. When it is necessary to release the fabric, the rotary table is rotated in the opposite direction so that the protrusion no longer abuts against the deflecting clamping plate, and the deflecting clamping plate can return to its original state. This method can conveniently and quickly clamp and release the fabric. Moreover, the abutment between the protrusion and the top of the deflecting clamping plate ensures that the clamping force on the fabric is reliable and constant.

[0013] Preferably, the protruding sidewall is formed as an inclined surface, and the sidewall of the deflection clamp is provided with rounded corners, which can abut against the inclined surface and slide relative to it.

[0014] By adopting the above technical solution, the inclined surface and rounded corner make the contact between the protrusion and the deflection clamp plate smoother during the rotation of the rotary table. As the rotary table rotates, the inclined surface abuts against the rounded corner and slides relative to it. The inclined surface provides a downward pressing force to the rounded corner and the deflection clamp plate, thereby automatically pressing down the deflection clamp plate and realizing a smooth transition in the process of the protrusion abutting and disengaging from the deflection clamp plate.

[0015] Preferably, a torsion spring is provided at the rotatable connection between the deflection clamp and the fixed clamp, and the torsion spring drives the deflection clamp to deflect away from the fixed clamp.

[0016] By adopting the above technical solution, when the rotating table rotates so that the protrusion no longer abuts against the deflection clamp, the elastic force of the torsion spring will drive the deflection clamp to automatically deflect away from the fixed clamp, thereby quickly releasing the fabric without manual operation and improving work efficiency.

[0017] Secondly, the high-toughness and wear-resistant polyester fabric provided in this application adopts the following technical solution: it includes a polyester fiber layer, a reinforcing layer, and a wear-resistant layer. The reinforcing layer is located between the polyester fiber layer and the wear-resistant layer. The polyester fiber layer is woven from polyester fibers, and the reinforcing layer is made of a blend of polyamide fibers and polyester fibers.

[0018] By adopting the above technical solutions, the polyester fiber layer itself has certain strength, abrasion resistance and easy processing, providing basic performance support for the fabric; the polyamide fiber in the reinforcing layer has high toughness and good impact resistance. After being blended with polyester fiber, it can effectively disperse stress, improve the overall toughness and tear resistance of the fabric, and reduce the possibility of the fabric breaking when subjected to external force pulling or friction; the abrasion-resistant layer further protects the internal polyester fiber layer and reinforcing layer, reducing the damage to the fabric caused by external friction.

[0019] Preferably, the wear-resistant layer is woven from ultra-high molecular weight polyethylene fibers.

[0020] By adopting the above technical solution, ultra-high molecular weight polyethylene fiber is a fiber spun from polyethylene with a molecular weight of 1 million to 5 million. Ultra-high molecular weight polyethylene fiber fabric has extremely high abrasion resistance, which is several times or even dozens of times that of ordinary fibers. The abrasion-resistant layer woven with this fiber can greatly improve the abrasion resistance of the fabric surface, so that it can still maintain good integrity and performance under long-term friction and wear environment.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a chute, slider, drive assembly, clamping assembly, and pressure plate, the fabric can be automatically tightened and wrinkles smoothed before hot pressing, minimizing the poor smoothing effect caused by relying solely on manual smoothing. The slider slides along the diagonal direction of the support platform, so that the fabric is evenly stressed on all four sides, improving the flatness of the fabric before hot pressing, reducing product defects caused by wrinkles during hot pressing, and ensuring the quality of hot pressing. 2. By setting up a motor, lead screw, sliding ring, sliding frame, and connecting rod, the position of all sliders is controlled synchronously to achieve stepless adjustment of fabric tension. The threaded engagement between the lead screw and the sliding ring has a self-locking characteristic, ensuring that the slider position is fixed and minimizing the risk of displacement or wrinkles caused by fabric loosening during hot pressing. 3. By setting fixed clamping plates, deflection clamping plates, rotating tables, protrusions, and torsion springs, the fabric can be quickly clamped and released, and the clamping force on the fabric can be guaranteed to be reliable and constant, minimizing local damage to the fabric during the clamping process.

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a hot pressing device. (Refer to...) Figure 1 It includes several support legs 11, all of which are fixedly mounted on a support platform 1, providing support for the support platform 1. A bracket 12 is fixedly mounted on the support platform 1. A cylinder 121 is fixedly mounted on the bracket 12, with the output end of the cylinder 121 facing downwards and a hot press plate 122 fixedly mounted on it. The cylinder 121 provides the power for the movement of the hot press plate 122, as well as the pressure during hot pressing, while the hot press plate 122 provides the temperature during hot pressing.

[0029] Reference Figure 1 The support platform 1 has diagonal grooves 13 at its four corners, extending through the upper and lower sides and corners of the support platform 1. A slider 131 is slidably disposed within the grooves 13, with its top extending out of the grooves 13. In this embodiment, dovetail grooves are formed on both sides of the grooves 13, and dovetail blocks are integrally formed on both sides of the slider 131. The dovetail blocks slide within the dovetail grooves, providing support for the slider 131's sliding movement within the grooves 13.

[0030] Reference Figure 1 A pressure plate 14 is fixedly installed on the support platform 1. The pressure plate 14 is located directly below the hot press plate 122. The pressure plate 14 blocks part of the sliding groove 13 and provides support for the fabric during hot pressing. The slider 131 has a relief groove 1311 on one end wall near the center of the support platform 1, into which the pressure plate 14 can extend.

[0031] Reference Figure 1 and Figure 3A drive assembly 2 is provided at the bottom of the support platform 1. The drive assembly 2 is used to synchronously drive all sliders 131 to move closer or further apart and to fix the position of sliders 131. Specifically, the drive assembly 2 includes a sliding frame 21, a sliding ring 22, a connecting rod 23, and a power component. The sliding frame 21 is fixed to the bottom of the support platform 1, and the sliding ring 22 slides and engages with the sliding frame 21 in the vertical direction. The power component is used to drive the sliding ring 22 to slide, and the power component includes a motor 24 and a lead screw 25. The motor 24 is fixed to the bottom of the support platform 1, and the lead screw 25 is coaxially fixed with the drive shaft of the motor 24. The sliding ring 22 is sleeved on the lead screw 25 and threadedly engaged with the lead screw 25. Four connecting rods 23 are evenly spaced along the circumference of the sliding ring 22. Each connecting rod 23 corresponds to one slider 131. One end of the connecting rod 23 is hinged to the bottom of the slider 131, and the other end of the connecting rod 23 is hinged to the sliding ring 22.

[0032] Reference Figure 1 and Figure 3 When the motor 24 rotates in the forward direction, the lead screw 25 engages with the sliding ring 22 and moves downward. The sliding ring 22 pulls one end of all the connecting rods 23 downward, causing the connecting rods 23 to converge towards the lead screw 25, and all the sliders 131 to move closer to each other. When the motor 24 rotates in the reverse direction, the lead screw 25 engages with the sliding ring 22 and moves upward. The sliding ring 22 pulls one end of all the connecting rods 23 upward, causing the connecting rods 23 to disperse, and all the sliders 131 to move away from each other, thereby driving all the sliders 131 to move synchronously.

[0033] Reference Figure 1 and Figure 2 A clamping assembly 3 is provided at one end of the slider 131 near the center of the support platform 1. The clamping assembly 3 is used to clamp the fabric. The clamping assembly 3 includes a fixed clamping plate 31, a deflecting clamping plate 32, a rotating platform 33, and a protrusion 34. The fixed clamping plate 31 is fixedly connected to the slider 131. The deflecting clamping plate 32 is located above the fixed clamping plate 31 and is rotatably connected to the fixed clamping plate 31. The rotation axis of the deflecting clamping plate 32 is horizontal. Rubber pads 36 are fixedly provided on the sides of the fixed clamping plate 31 and the deflecting clamping plate 32 that are close to each other. When the deflecting clamping plate 32 deflects to the side closer to the fixed clamping plate 31, the fixed clamping plate 31 and the deflecting clamping plate 32 can hold the corners of the fabric through the rubber pads 36.

[0034] Reference Figure 1 and Figure 2The rotating platform 33 is rotatably connected to the fixed clamping plate 31, and the rotation axis of the rotating platform 33 is vertical. A protrusion 34 is integrally formed at the bottom of the rotating platform 33, and the protrusion 34 can abut against the top of the deflecting clamping plate 32. Specifically, the sidewall of the protrusion 34 is provided with an inclined surface 341, and the sidewall of the deflecting clamping plate 32 is provided with a rounded corner 321, which can abut against the inclined surface 341 and slide relative to it. When the rotating platform 33 rotates, the inclined surface 341 abuts against the rounded corner 321 and slides relative to it, and the inclined surface 341 provides a downward pressing force to the rounded corner 321 and the deflecting clamping plate 32 until the bottom of the protrusion 34 completely abuts against the top of the deflecting clamping plate 32. At this time, the deflecting clamping plate 32 and the fixed clamping plate 31 ensure the clamping of the corner of the fabric. A torsion spring is provided at the rotatable connection between the deflecting clamping plate 32 and the fixed clamping plate 31, and the torsion spring drives the deflecting clamping plate 32 to deflect away from the fixed clamping plate 31.

[0035] The implementation principle of the hot pressing device in this application embodiment is as follows: Before hot pressing the fabric, the motor 24 drives the lead screw 25 to rotate in the forward direction, the sliding ring 22 moves down, the connecting rod 23 converges, and the sliders 131 move closer to each other, with the clearance groove 1311 allowing the sliders 131 to avoid the pressure plate 14. Then, the four corners of the fabric are placed between the fixed clamping plate 31 and the deflection clamping plate 32 of each slider 131, and the rotary table 33 is rotated. When the inclined surface 341 of the protrusion 34 contacts the rounded corner 321 of the deflection clamping plate 32, the downward pressure component of the inclined surface 341 pushes the deflection clamping plate 32 to deflect around the horizontal axis toward the fixed clamping plate 31 until the protrusion 34 completely abuts the top of the deflection clamping plate 32. The fabric is clamped by the rubber pads 36 on the fixed clamping plate 31 and the deflection clamping plate 32, achieving fast and stable clamping. Then, motor 24 drives lead screw 25 to rotate in the opposite direction, causing sliding ring 22 to move downwards. This movement, via connecting rod 23, pulls four sliders 131 synchronously towards the center along the diagonal direction of support platform 1, thereby tightening the fabric. Finally, cylinder 121 drives hot press plate 122 to press down, hot pressing the fabric taut on pressure plate 14. Since the fabric has been tensioned and flattened by sliders 131, wrinkles are greatly reduced during hot pressing, improving molding quality.

[0036] This application also discloses a high-toughness, abrasion-resistant polyester fabric. (Refer to...) Figure 1 and Figure 4The fabric comprises a polyester fiber layer 4, a reinforcing layer 5, and an abrasion-resistant layer 6, with the reinforcing layer 5 located between the polyester fiber layer 4 and the abrasion-resistant layer 6. The polyester fiber layer 4 is woven from polyester fibers and possesses inherent strength, abrasion resistance, and ease of processing, providing fundamental performance support for the fabric. The reinforcing layer 5 is a blend of polyamide fibers and polyester fibers. The polyamide fibers in the reinforcing layer 5 exhibit high toughness and good impact resistance; when blended with polyester fibers, they effectively disperse stress, improving the overall toughness and tear resistance of the fabric. The abrasion-resistant layer 6 is woven from ultra-high molecular weight polyethylene (UHMWPE) fibers. UHMWPE fibers are fibers spun from polyethylene with a molecular weight between 1 million and 5 million. UHMWPE fiber fabrics possess extremely high abrasion resistance, several times or even tens of times that of ordinary fibers. The abrasion-resistant layer 6, woven from this fiber, significantly enhances the abrasion resistance of the fabric surface. The polyester fiber layer 4, the reinforcing layer 5, and the abrasion-resistant layer 6 are stacked sequentially, and after adding adhesive at the joints, they are placed between the hot press plate 122 and the support plate 14 for hot pressing. The adhesive can be polyurethane hot melt adhesive.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
