Description

Technical Field

[0001] The present invention relates to the technical field of stretching and setting of grey fabrics, and particularly to a stretching and setting device and method for highly wear-resistant polyester woven grey fabrics. Background Art

[0002] A highly wear-resistant polyester woven grey fabric is a grey fabric mainly made of polyester fibers and woven by a weaving process; polyester fibers themselves have many excellent properties such as high strength, good elasticity, and corrosion resistance. After being woven into a grey fabric by the weaving method, due to the characteristics of the warp and weft interlaced structure of weaving, the grey fabric has good stability and stiffness.

[0003] During the production of polyester woven grey fabrics, stretching and setting are usually required to make the size of the polyester woven grey fabric more stable and eliminate internal stress to optimize the performance of the grey fabric. However, in the prior art, only simple stretching is used for the setting operation, which may cause the thermal movement of the molecular chains in the polyester woven grey fabric to remain active and easily return to the initial disordered state, and the setting effect cannot be well maintained. Eventually, the grey fabric may still be prone to problems such as deformation and wrinkles. In view of this, the present invention is specifically proposed. Summary of the Invention

[0025] Compared with the prior art, the present invention provides a stretching and setting device and method for a highly wear-resistant polyester woven grey fabric, which has the following beneficial effects:

[0026] 1. For the stretching and setting device of the highly wear-resistant polyester woven grey fabric, the steps of stretching and setting the grey fabric are divided into three steps: preheating, setting and cooling. During the early processing such as weaving of the polyester woven grey fabric, the fibers are in a relatively loose and disordered state, and the size is prone to change; through preheating, the grey fabric can be evenly heated to prepare for the subsequent heat setting. During heat setting, the fiber molecular chains are rearranged and oriented under the action of heat and external force, and then this morphology is fixed by cooling, so that the size of the grey fabric can be stabilized, and it is not easy to have size changes such as shrinkage and elongation during subsequent use, cutting, sewing, etc., ensuring the specification consistency of the product; moreover, during the stretching and setting process, through the heating of the first heating press roller and the second heating press roller, the wrinkles on the grey fabric can be flattened, making the fabric surface smoother and flatter, improving its appearance quality, making it more in line with the requirements of subsequent processes such as printing and dyeing and making finished products, and also enhancing the aesthetics of the final product.

[0027] 2. The stretching and setting device for the highly wear-resistant polyester woven grey fabric. The mutual cooperation of the first heating roller and the second heating roller can, on the one hand, make the heating effect of the polyester woven grey fabric better and more comprehensive, further improving the setting effect. On the other hand, it can compress the polyester woven grey fabric by the second heating roller, enabling the fibers in the grey fabric to be closer to each other, reducing the gaps between the fibers, thereby increasing the density of the fabric and further enhancing the wear resistance. It also helps to improve the functionality of the grey fabric such as wind resistance and waterproofness. The cooling process can quickly cool down the fibers, and the activity ability of the molecular chains rapidly decreases and is "frozen" in the new arrangement form, thus fixing the structure of the set fabric, ensuring that the fabric size, flatness, and various physical properties reach the expected stable state, avoiding structural changes during subsequent use and processing, and thereby improving the dimensional stability of the polyester woven grey fabric and making the stretching and setting effect better.

[0028] 2. The stretching and setting device for the highly wear-resistant polyester woven grey fabric. By setting spiral channels on the first heating roller, the second heating roller, and the cooling roller, it can increase the flow area and time of the heat-conducting oil or cold water in the channels. The spiral trajectories are evenly distributed inside the roller body and can then be evenly transferred to the surface of the roller, enabling the polyester woven grey fabric in contact with the roller body to be heated or cooled and set in all directions and evenly.

Specific embodiments

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0039] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0040] Embodiment 1:

[0041] Refer to Figures 1 - 8, A stretching and shaping device for a highly wear-resistant polyester woven grey fabric, including a housing 1, and further including partition plates 103 fixedly arranged on the inner wall of the housing 1. There are two partition plates 103, and the two partition plates 103 divide the housing 1 into a preheating chamber 2, a shaping chamber 3, and a cooling chamber 4; a drying box 202 is arranged in the preheating chamber 2, and the drying box 202 is fixedly connected to the housing 1; on the inner wall of the shaping chamber 3, two first rotating shafts 301 and one second rotating shaft 302 are fixedly arranged. First heating pressing rollers 303 are rotatably arranged on the two first rotating shafts 301, a second heating pressing roller 304 is rotatably arranged on the second rotating shaft 302, and the second heating pressing roller 304 is arranged between the two first heating pressing rollers 303; on the inner wall of the cooling chamber 4, two third rotating shafts 402 are fixedly arranged, and cooling rollers 403 are rotatably connected to the two third rotating shafts 402; one end of the housing 1 close to the preheating chamber 2 is provided with a feed port 101, one end of the housing 1 close to the cooling chamber 4 is provided with a discharge port 102, and spiral channels 310 are arranged on the first heating pressing rollers 303, the second heating pressing rollers 304, and the cooling rollers 403.

[0042] A first auxiliary roller 201 is further arranged in the preheating chamber 2, and a second auxiliary roller 401 is arranged in the cooling chamber 4. The polyester woven grey fabric enters the housing 1 through the feed port 101, passes through the first auxiliary roller 201 and the drying box 202 in sequence and then enters the shaping chamber 3, then passes through the first heating pressing rollers 303 and the second heating pressing rollers 304 and then enters the cooling chamber 4, and finally passes through the cooling rollers 403 and the second auxiliary roller 401 in sequence and exits from the discharge port 102.

[0043] In this embodiment, during use, first, the highly wear-resistant polyester woven grey fabric is threaded into the housing 1 through the feed port 101, and then enters the drying box 202 after being guided by the first auxiliary roller 201 for preliminary heating operation to achieve the preheating effect. It should be noted that the drying box 202 adopted in this application uses existing technology and can achieve the preheating effect of the polyester woven grey fabric. Then, it enters the shaping chamber 3 through the gap on the partition plate 103. Refer to Figure 3 , the polyester woven grey fabric will sequentially pass over the top of the left first heating pressing roller 303, then pass under the second heating pressing roller 304, and finally pass over the top of the right first heating pressing roller 303 and exit. The mutual cooperation of the first heating pressing roller 303 and the second heating pressing roller 304 can, on the one hand, make the heating effect of the polyester woven grey fabric better and more comprehensive, further improving the shaping effect. On the other hand, it can compress the polyester woven grey fabric by the second heating pressing roller 304, so that the fibers in the fabric can be closer to each other, reducing the gaps between the fibers, thereby increasing the density of the fabric and further enhancing the wear resistance; it also helps to improve the functions such as wind resistance and waterproofness of the fabric.

[0044] After the polyester woven grey fabric passes through the shaping cavity 3, it will pass through the partition plate 103 and enter the cooling cavity 4. Then, through the cooling roller 403, the grey fabric can be preliminarily cooled. After that, it is guided by the second auxiliary roller 401 and discharged from the discharge port 102. The cooling process can quickly cool down the fibers, and the activity of the molecular chains decreases rapidly and is "frozen" in the new arrangement form, thereby fixing the structure of the shaped fabric, ensuring that the fabric size, flatness, and various physical properties reach the expected stable state, avoiding structural changes during subsequent use and processing, thus improving the dimensional stability of the polyester woven grey fabric and making the stretching and shaping effect better.

[0045] Embodiment 2:

[0046] Refer to Figures 1 - 8 , a stretching and shaping device for a highly wear-resistant polyester woven grey fabric, including a housing 1, and further including partition plates 103 fixedly arranged on the inner wall of the housing 1. There are two partition plates 103, and the two partition plates 103 divide the housing 1 into a preheating cavity 2, a shaping cavity 3, and a cooling cavity 4; a drying box 202 is arranged in the preheating cavity 2, and the drying box 202 is fixedly connected to the housing 1; on the inner wall of the shaping cavity 3, two first rotating shafts 301 and a second rotating shaft 302 are fixedly arranged. First heating pressing rollers 303 are rotatably arranged on the two first rotating shafts 301, and a second heating pressing roller 304 is rotatably arranged on the second rotating shaft 302. The second heating pressing roller 304 is arranged between the two first heating pressing rollers 303; on the inner wall of the cooling cavity 4, two third rotating shafts 402 are fixedly arranged, and cooling rollers 403 are rotatably connected to the two third rotating shafts 402; one end of the housing 1 close to the preheating cavity 2 is provided with a feed port 101, one end of the housing 1 close to the cooling cavity 4 is provided with a discharge port 102, and spiral channels 310 are arranged on the first heating pressing rollers 303, the second heating pressing roller 304, and the cooling rollers 403.

[0047] Refer to Figures 4 - 8 , a support plate 5 is arranged on the outer wall of the housing 1, a motor 501 is arranged on the support plate 5, an output shaft 502 is arranged at the output end of the motor 501, and a driving gear 503 and a cam 504 are arranged on the output shaft 502.

[0048] Refer to Figures 4 - 8 , annular plates 305 are arranged on the outer walls of the two first heating pressing rollers 303 and the second heating pressing roller 304. The annular plates 305 are rotatably connected to the housing 1, driven gears 306 that mesh with each other are arranged on the outer walls of the annular plates 305, and the driven gear 306 located in the middle meshes with the driving gear 503.

[0049] In this embodiment, by starting the motor 501 on the support plate 5, the output shaft 502 at the output end can be driven to rotate, thereby driving the driving gear 503 and the cam 504 to rotate. When the driving gear 503 rotates, it will mesh with the driven gear 306 connected to the annular plate 305 on the second heating and pressing roller 304. The second heating and pressing roller 304 is driven to rotate through the driven gear 306. Since the driven gears 306 that mesh with each other are provided on both of the two first heating and pressing rollers 303 and one second heating and pressing roller 304, therefore, the first heating and pressing rollers 303 and the second heating and pressing roller 304 can be driven to rotate synchronously, so as to assist in driving the high-wear-resistant polyester woven grey fabric to move, and it can be better processed. It should be noted that while the first heating and pressing rollers 303 and the second heating and pressing roller 304 are rotating, since the first rotating shaft 301 and the second rotating shaft 302 are fixedly arranged on the housing 1, the first rotating shaft 301 and the second rotating shaft 302 will not rotate synchronously. The annular plate 305 is provided to better drive the first heating and pressing rollers 303 and the second heating and pressing roller 304 to rotate.

[0050] Embodiment 3:

The second heating and pressing roller 304 is arranged between the two first heating and pressing rollers 303; two third rotating shafts 402 are fixedly arranged on the inner wall of the cooling chamber 4, and cooling rollers 403 are rotatably connected to both of the two third rotating shafts 402; one end of the housing 1 close to the preheating chamber 2 is provided with a feed inlet 101, and one end of the housing 1 close to the cooling chamber 4 is provided with a discharge outlet 102. Spiral channels 310 are provided on the first heating and pressing rollers 303, the second heating and pressing roller 304 and the cooling rollers 403.

[0052] Referring to Figures 4 - 8 , two boxes 6 are arranged on the outer wall of the housing 1, the two boxes 6 are respectively arranged on both sides of the support plate 5, and cylinders 601 are fixedly arranged in both of the two boxes 6. A water suction pipe 606 and a drain pipe 607 are connected to the outer wall of the cylinder 601.

[0053] Referring to Figures 4 - 8, both ends of the first rotating shaft 301 and the second rotating shaft 302 are connected with first communicating pipes 307, both ends of the two third rotating shafts 402 are connected with second communicating pipes 404, and the first communicating pipes 307 at one end of the first rotating shaft 301, the second rotating shaft 302 and the third rotating shaft 402 are connected with a mounting pipe 308 through a four-way pipe. The drain pipes 607 on the two cylinders 601 are respectively connected with the mounting pipe 308 and the second communicating pipe 404.

The two delivery pipes 608 are respectively communicated with the two boxes 6.

[0054] Referring to Figures 4 - 8 , a piston 602 is slidably connected in the cylinder 601. A push rod 603 is connected to the piston 602. One end of the push rod 603 away from the piston 602 is fixedly connected with a push plate 604. The cam 504 cooperates with the push plate 604. A water suction pipe 606 is further provided at the bottom of the cylinder 601.

[0056] In this embodiment, when the motor 501 is started, it will not only drive the driving gear 503 to rotate, but also drive the cam 504 to rotate. When the cam 504 rotates, it will cooperate with the push plates 604 on both sides of it. Under the action of the spring 605, it can drive the push plates 604 on both sides to reciprocate, thereby driving the piston 602 to reciprocate in the cylinder 601 through the push rod 603. Since one-way valves are provided on both the water suction pipe 606 and the drain pipe 607, when the piston 602 moves deep into the cylinder 601, it can squeeze the liquid in the cylinder 601 to discharge it through the drain pipe 607. When the piston 602 moves to the other side, it can draw liquid through the water suction pipe 606. The one-way valves provided can make the water suction pipe 606 only allow liquid to enter the cylinder 601, and the liquid in the cylinder 601 can only be discharged through the drain pipe 607, thereby realizing the reciprocating flow of the liquid.

[0057] It should be noted that there are two boxes 6 in this application. Referring to Figure 2 and Figure 4, there is heat-conducting oil placed in the box body 6 on the right side. Through the heat-conducting oil, the first heating roller 303 and the second heating roller 304 can be heated, enabling better heat setting of the polyester woven grey fabric. Cold water is added to the box body 6 on the left side. The cold water can enter the cooling roller 403 through the drain pipe 607, thereby cooling the grey fabric through the cooling roller 403, improving the setting effect. After circulation, the heat-conducting oil and cold water will be discharged from the first connecting pipe 307 and the second connecting pipe 404 on the other side of the housing, and then enter the conveying pipe 608 and re-enter the box body 6. There are also a water injection port and a drain port on the box body 6 for convenient water injection and drainage.

[0058] Both ends of the first rotating shaft 301, the second rotating shaft 302, and the third rotating shaft 402 are provided with connecting grooves 309 communicating with the spiral channel 310. The connecting grooves 309 of the first rotating shaft 301 and the second rotating shaft 302 communicate with the first connecting pipe 307, and the connecting groove 309 on the third rotating shaft 402 communicates with the second connecting pipe 404.

[0060] Through the provided spiral channel 310, the flowing area and time of the heat-conducting oil or cold water in the channel can be increased. The spiral trajectory is evenly distributed inside the roller body, and then can be evenly transferred to the surface of the roller, enabling the polyester woven grey fabric in contact with the roller body to be heated or cooled and set comprehensively and evenly.

[0061] Example 4:
