Description

Technical Field

[0001] This invention relates to the field of fabric processing technology, specifically to a stretching and setting device and a fabric preparation method for all-cotton four-way stretch fabric. Background Technology

[0002] Because of its wet-heat plasticity, cotton fabrics often experience deformation and unevenness after wet-heat processing such as scouring, bleaching, dyeing, and washing during printing and dyeing. Therefore, a tenter frame is needed during fabric preparation to stretch and set the fabric. The tenter frame applies lateral tension to both sides of the fabric box, tightening the fabric and setting its shape to maintain a smooth and flat state. However, existing tenter frame equipment often uses needle plates to fix the fabric when applying tension, which can damage the fabric surface. Furthermore, during the stretching process, deformation holes can easily form on the fabric surface, reducing the processing effect and fabric integrity.

[0003] The shortcomings of existing fabric stretching and setting equipment are:

[0004] 1. Patent document CN221094565U mainly considers how to clean the fabric surface during the fabric stretching and setting process, without considering how to avoid damage to the fabric itself or other adverse effects.

[0005] 2. Patent document CN216514657U mainly considers how to stretch and set the fabric to various degrees, but does not consider how to improve the stretching and setting equipment's ability to handle fabrics of different thicknesses.

[0006] 3. Patent document CN222226842U mainly considers how to stretch and shape the fabric at multiple locations, but does not consider how to improve the stretching and shaping equipment's ability to handle fabrics of different widths.

[0007] 4. Patent document CN215405064U mainly considers how to adjust the fabric treatment effect by adjusting the position of the setting roller, but does not consider how to maintain the relative position between the two sides of the fabric and the stretching frame. Summary of the Invention

[0019] A tenter frame for four-way stretch fabric, the fabric preparation method of which is as follows:

[0020] S1. Set the fabric width and weft density data, weave the fabric according to the set data, mercerize the woven fabric, perform airflow alkaline boiling on the mercerized fabric, and then use a stretching and setting device to stretch and set the airflow alkaline boiled fabric.

[0021] S2. Based on the thickness of the fabric to be stretched and shaped, adjust the distance between the two sets of stretching frames using the adjustment component one. Based on the fabric width, adjust the position of the support frame and take-up roller using the moving seat, and simultaneously adjust the position of the auxiliary moving plate.

[0022] S3. After the stretching area is adjusted, the fabric is transferred to the I-beam board through the upper fabric rack, and while the fabric moves to the right along the surface of the I-beam board, the stretching frame is used to stretch and shape the fabric.

[0023] S4. The fabric that has been stretched and set continues to move to the right, so that the fabric moves into the heat setting box. Hot steam is introduced into the heat setting box to heat set the fabric.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention utilizes a transmission chain and a stretching assembly. The transmission chain drives the stretching assembly to move, ensuring the fabric moves synchronously with the stretching frames on its upper and lower edges. A servo motor drives the stretching frames to rotate, applying tension to both sides of the fabric and achieving stretching. A miniature electric actuator then moves a moving frame, causing the pressing blocks to adhere to the fabric surface, thus fixing the fabric in place. This prevents the fabric from springing back during movement, improving the stretching effect. Furthermore, the pressing blocks replace needle-plate fixing, preventing damage to the fabric surface and avoiding rough edges, thus improving the fabric processing results.

[0026] 2. This invention, by installing an adjustment component, including a fixed sleeve and a square rod, uses a servo motor to drive a miniature bidirectional lead screw to rotate, thereby causing two sets of tenter frames to move closer or further apart, achieving the purpose of adjusting the distance between the two sets of tenter frames. This enables tentering and shaping of fabrics of different thicknesses, improving the applicability of the tentering and shaping equipment. By embedding a rotating disk at the top of the bracket, when the servo motor drives the rotating rod to rotate, the rotating rod drives the fixed sleeve and the square rod to rotate, which in turn drives the tenter frames to rotate. The rotating disk rotates synchronously, avoiding obstruction to the rotation process of the tenter frames and ensuring their normal use.

[0027] 3. This invention, equipped with a movable seat, a take-up roller, and an elastic plate, uses a servo motor to drive the take-up roller to rotate, thereby winding the elastic plate. This reduces the width of the fabric conveying area formed by the top of the I-beam and the two side plates. During the take-up roller's winding process, the horizontal and vertical positions of the movable seat and support frame are adjusted to ensure that the top of the elastic plate and the top of the I-beam are on the same plane. This helps to avoid wrinkles and other unevenness in the fabric during transmission, improving the fabric stretching and setting effect. Furthermore, the position of the auxiliary moving plate is adjusted to maintain the relative position between the stretching component and the edge of the elastic plate. By setting an adjustable width conveying area and an adjustable position stretching component, stretching and setting operations can be performed on fabrics of different widths, thus expanding the applicability of the stretching and setting equipment.

[0028] 4. This invention reduces the distance between the tenter frame and the edge of the elastic roll plate by setting a side plate with a horizontal top between the tenter frame and the take-up roller, and makes both sides of the fabric conveying area horizontal, avoiding the phenomenon of the fabric falling downward along the surface of the elastic roll plate that is rolled up along the outer wall of the take-up roller. This allows the sides of the fabric to be located between the two sets of tenter frames, which facilitates the shaping operation of the fabric from both sides using the tenter frame. Furthermore, by setting a spring to connect the support frame and the connecting ear, the spring's own elasticity keeps the side plate in close contact with the outer wall of the elastic roll plate wrapped around the outer wall of the take-up roller, which helps to improve the relative positional stability between the side plate and the elastic roll plate.

[0043] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An embodiment of the present invention provides a tenter frame for a 100% cotton four-way stretch fabric, comprising a tenter area 1, the tenter area 1 comprising two sets of vertical plates 4, an I-beam plate 5 installed on one side of the two sets of vertical plates 4 that are close to each other, forming a concave area between the I-beam plate 5 and the vertical plates 4, an auxiliary moving plate 6 embedded in the outer wall of the vertical plates 4, and the length of the auxiliary moving plate 6 being less than the length of the concave area, a motor 7 installed on the outer wall of the auxiliary moving plate 6, a transmission gear 8 sleeved on the outer wall of the output end of the motor 7, a transmission chain 9 meshing with the outer wall of the transmission gear 8, a tenter frame fixedly installed on the outer wall of the transmission chain 9, and the transmission gear 8, the transmission chain 9 and the tenter frame being located inside the concave area;

[0044] The tensioning assembly includes a horizontal plate 10 fixedly mounted on the outer surface of the drive chain 9. A bracket 11, E-shaped, is mounted on one end of the horizontal plate 10 near the I-beam 5. A servo motor 12 and a positioning sensor 22 are mounted on the top of the bracket 11, with the positioning sensor 22 located to the left of the servo motor 12. A rotating rod 13 is connected to the output end of the servo motor 12, passing through the top of the bracket 11. An adjustment assembly 14 is fitted onto the outer wall of the rotating rod 13. Two sets of adjustment assemblies 14 are installed inside the bracket 11. A tensioning frame 15 is mounted on one end of the adjustment assembly 14. A miniature electric actuator 16 is installed inside the tensioning frame 15, and the output end of the miniature electric actuator 16 is connected to a moving frame 17. The bottom end of the movable frame 17 extends to the bottom of the stretching frame 15. A fixing plate 18 is installed at the bottom end of the movable frame 17. A pressing block 19 is installed at the bottom of the fixing plate 18. The pressing block 19 is made of non-slip rubber. A ball bearing 20 is embedded in the bottom of the stretching frame 15. The ball bearing 20 is located below the movable frame 17. The fixing plate 18 is sleeved on the outside of the ball bearing 20. An angle sensor 21 is installed at the top of the stretching frame 15. The angle sensor 21 is used to detect the rotation angle of the stretching frame 15. A positioning detection plate 1 23, a positioning detection plate 24, and a positioning detection plate 3 25 are installed between the two sets of vertical plates 4. The positioning detection plate 1 23, the positioning detection plate 24, and the positioning detection plate 3 25 are used to cooperate with the positioning sensor 22 to detect the position of the bracket 11.

[0045] The arrival detection plate 1 23 is located to the left of the arrival detection plate 24. Arrival detection plates 1 23 and 24 are located above the I-beam plate 5. Arrival detection plate 3 25 is located below the I-beam plate 5. Arrival detection plate 1 23 is located above the left-side set of transmission gears 8. Arrival detection plates 24 and 3 25 are located on the upper and lower sides of the right-side set of transmission gears 8, respectively. The distance between the bottom of arrival detection plate 1 23 and the top of the I-beam plate 5 is X1. The distance between the bottom of arrival detection plate 24 and the top of the I-beam plate 5 is X2. The distance between the top of arrival detection plate 3 25 and the bottom of the I-beam plate 5 is X3, where X1 is less than X2 and X3 is less than X3. When the positioning sensor 22 reaches below the positioning detection plate 1 23, the positioning sensor 22 obtains the distance between itself and the bottom of the positioning detection plate 1 23 as a first preset distance, and the first preset distance is less than X1. When the positioning sensor 22 reaches below the positioning detection plate 24, the positioning sensor 22 obtains the distance between itself and the bottom of the positioning detection plate 24 as a second preset distance, and the second preset distance is greater than X1 and less than X2. When the positioning sensor 22 reaches the top of the positioning detection plate 3 25, the positioning sensor 22 obtains the distance between itself and the top of the positioning detection plate 3 25 as a third preset distance, and the third preset distance is greater than X2 and less than X3.

[0046] Furthermore, the fabric to be stretched and shaped is transferred from the upper fabric frame 2 to the top of the I-beam 5 in the stretching area 1. When the transmission chain 9 drives the stretching frame 15 to move above the I-beam 5, the two sets of stretching frames 15 are located on the upper and lower sides of the fabric, respectively, and the ball bearings 20 at the bottom of the stretching frame 15 are in contact with the fabric surface. The transmission gear 8 is driven to rotate by the motor 7, and the transmission gear 8 drives the transmission chain 9 to rotate, thereby causing the transmission chain 9 to drive the stretching frame 15 and the fabric to move synchronously to the right. The position sensor 22 detects the position of the bracket 11 and the stretching frame 15. When the detection data obtained by the position sensor 22 is the first set distance, it indicates that the bracket 11 and the stretching frame 15 have reached below the position detection plate 23. Then, the servo motor 12 is started to drive the rotating rod 13 to rotate, and the adjusting component 14 drives the stretching frame 15 to rotate, thereby causing the stretching frame 15 to rotate along the fabric surface around the rotating rod 13 towards the side of the fabric. The stretching frame 15 is rotated outward to apply tension to the fabric on both sides, thereby stretching the fabric to achieve the purpose of stretching. During the rotation of the stretching frame 15, the rotation angle of the stretching frame 15 is detected by the angle sensor 21. When the angle sensor 21 detects that the rotation angle of the stretching frame 15 is the set angle, the servo motor 12 stops running and the micro electric push rod 16 is activated to push the moving frame 17 toward the fabric surface. The set angle is the rotation angle of the stretching frame 15 when one corner of the fixing plate 18 at the bottom of the stretching frame 15 is in contact with the side of the fabric. The moving frame 17 drives the pressing block 19 to be in contact with the fabric surface to fix the fabric, thereby fixing the fabric and avoiding the stretching rebound phenomenon of the fabric during the movement. This is beneficial to improving the stretching effect. In addition, by setting the pressing block 19 to fix the fabric, the needle plate fixing is replaced, thereby avoiding damage to the fabric surface and avoiding defects such as burrs on the side of the fabric.

[0047] The transmission chain 9 drives the stretching frame 15 to move synchronously to the right with the fabric. When the detection data obtained by the positioning sensor 22 is the second set distance, it indicates that the bracket 11 and the stretching frame 15 have reached below the positioning detection plate 24. The micro electric push rod 16 is activated to shorten, and the micro electric push rod 16 pulls the moving frame 17 to move, which in turn drives the fixed plate 18 to move, causing the pressing block 19 to separate from the fabric surface. The transmission chain 9 drives the bracket 11 and the stretching frame 15 to continue moving. When the detection data obtained by the positioning sensor 22 is the third set distance, it indicates that the bracket 11 and the stretching frame 15 have reached above the positioning detection plate 25. The servo motor 12 is activated to rotate in the reverse direction, which drives the rotating rod 13 to rotate in the reverse direction, thereby driving the bracket 11 and the stretching frame 15 back to the initial state when no rotation occurred. This makes it convenient to reuse the stretching frame 15 to stretch and shape the fabric, which helps to improve the stretching and shaping efficiency of the fabric.

[0048] Please see Figure 4 and Figure 5An embodiment of the present invention provides a stretching and setting device for all-cotton four-way stretch fabric, comprising an adjustment component 14, the adjustment component 14 including two sets of fixing sleeves 26 sleeved on the outer wall of a rotating rod 13, a square rod 27 penetratingly connected to the top and bottom of a support 11, and the fixing sleeves 26 being disposed on the outer wall of the square rod 27, a stretching frame 15 being connected to the bottom end of the upper set of square rods 27 and the top end of the lower set of square rods 27, a rotating disk 28 being embedded in the top of the support 11, and the rotating disk 28 being located on the right side of the square rods 27, a servo motor 29 being installed on the top of the rotating disk 28, the output end of the servo motor 29 being connected to a miniature bidirectional lead screw 30, and the stretching frame 15 being sleeved on the outer wall of the miniature bidirectional lead screw 30.

[0049] Furthermore, servo motor 29 drives miniature bidirectional lead screw 30 to rotate, thereby causing the two sets of tenter frames 15 to move closer or further apart, achieving the purpose of adjusting the distance between the two sets of tenter frames 15. This enables tentering and shaping of fabrics of different thicknesses, improving the applicability of the tentering and shaping equipment. When the tenter frame 15 moves, it drives the square rod 27 to move up or down along the inner wall of the fixed sleeve 26. During the up-and-down movement of the tenter frame 15, it limits the movement of the tenter frame 15 to prevent it from rotating. At the same time, by fitting the fixed sleeve 26 onto the outer wall of the square rod 27 and embedding the rotating disk 28 at the top of the bracket 11, when the servo motor drives the rotating rod 13 to rotate, the rotating rod 13 drives the fixed sleeve 26 and the square rod 27 to rotate, which in turn drives the tenter frame 15 to rotate. The rotating disk 28 rotates synchronously, avoiding obstruction to the rotation process of the tenter frame 15 and ensuring the normal use of the tenter frame 15.

[0050] Please see Figure 6 , Figure 7 , Figure 8 and Figure 10One embodiment of the present invention provides a tenter frame for a 100% cotton four-way stretch fabric. A mounting frame 31 is connected to the bottom of an I-beam plate 5. The mounting frame 31 has an L-shaped plate structure. A telescopic rod 32 is mounted on the top of the mounting frame 31, providing installation space for the telescopic rod 32. A movable seat 33 is connected to the output end of the telescopic rod 32. A support rod 46 is installed between two sets of vertical plates 4. The movable seat 33 is fitted onto the outer wall of the support rod 46, and the support rod 46 is located on the left and right sides of the telescopic rod 32, providing support for the movable seat 33. This ensures the stability of the moving seat 33. A telescopic rod 34 is installed on the top of the moving seat 33. The output end of the telescopic rod 34 is connected to a support frame 35. A servo motor 36 is installed on the top plate of the support frame 35. The output end of the servo motor 36 is connected to a take-up roller 37. The take-up roller 37 is located inside the concave area. An elastic plate 38 is wound on the outer wall of the take-up roller 37. One end of the elastic plate 38 is fixedly connected to the inner wall of the long side of the concave area of ​​the I-beam plate 5. The width of the elastic plate 38 is the same as the length of the concave area along the setting direction of the vertical plate 4.

[0051] A support 43 is installed on the outer wall of the auxiliary transfer plate 6 facing the side plate 39 of the take-up roller 37. A servo motor 42 is installed on the back of the vertical plate 4. The output end of the servo motor 7 is connected to a bidirectional lead screw 44. A guide rod 45 is installed between the two sets of vertical plates 4, and the guide rod 45 is located below the bidirectional lead screw 44. The support 43 is sleeved on the outer wall of the bidirectional lead screw 44 and the guide rod 45.

[0052] Furthermore, by setting a servo motor 36 to drive the take-up roller 37 to rotate, the elastic roll 38 is wound up, reducing the width of the fabric conveying area formed by the top of the I-beam 5 and the rolls on both sides. During the winding process of the take-up roller 37, the telescopic rod pulls the moving seat 33 to move, causing the moving seat 33 to move the support seat and the take-up roller 37 towards the I-beam 5. During the winding process, according to the thickness of the elastic roll 38 and the number of winding layers, the telescopic rod 34 is activated to move the support plate downward, thereby causing the take-up roller 37 to be finely adjusted downward, ensuring that the top of the elastic roll 38 and the top of the I-beam 5 are in the same plane, which helps to avoid... To prevent wrinkles and unevenness in the fabric during transport, the fabric stretching and setting effect is improved. When the take-up roller 37 moves and the elastic winding plate 38 is wound up, the servo motor 42 is activated to drive the bidirectional lead screw 44 to rotate, which in turn drives the support 43 to move along the outer wall of the guide rod 45. The support 43 drives the two sets of auxiliary moving plates 6 to move closer to each other, which in turn drives the transmission gear 8, transmission chain 9, and stretching assembly to move inward, ensuring the relative position of the stretching assembly and the edge of the elastic winding plate 38. By setting an adjustable width conveying area and an adjustable position stretching assembly, stretching and setting operations can be performed on fabrics of different widths, which helps to improve the applicability of the stretching and setting equipment.

[0053] Please see Figure 7 , Figure 9 and Figure 10 An embodiment of the present invention provides a stretching and setting device for a 100% cotton four-way stretch fabric. A side plate 39 is provided in the concave area of ​​the I-beam 5, and the side plate 39 is located between the vertical plate 4 and the take-up roller 37. The top of the side plate 39 is on the same horizontal plane as the top of the elastic roll plate 38 and the top of the I-beam 5. An arc-shaped side is provided on the side of the side plate 39 facing the take-up roller 37, and the arc-shaped side is in contact with the outer wall of the elastic roll plate 38 being taken up. Connecting ears 40 are installed on the left and right outer walls of the side plate 39, and the connecting ears 40 extend to the left and right sides of the I-beam 5, respectively. A spring 41 is installed on the outer wall of the connecting ears 40 facing the take-up roller 37, and one end of the spring 41 is fixedly connected to the outer wall of the support frame 35.

[0054] Furthermore, by setting a side plate 39 with a horizontal top between the tenter frame 15 and the take-up roller 37, the distance between the tenter frame 15 and the edge of the elastic roll plate 38 is reduced, and the two sides of the fabric conveying area are made horizontal. This avoids the phenomenon of the fabric falling downward along the surface of the elastic roll plate 38 that is rolled up along the outer wall of the take-up roller 37. As a result, the side of the fabric is located between the two sets of tenter frames 15, which facilitates the shaping operation of the fabric from both sides using the tenter frame 15. In addition, by setting a spring 41 to connect the support frame 35 and the connecting ear 40, when the take-up roller 37 performs the take-up or unwinding operation on the elastic roll plate 38, the spring 41 itself keeps the side plate 39 in contact with the outer wall of the elastic roll plate 38 wrapped by the outer wall of the take-up roller 37, which helps to improve the relative positional stability between the side plate 39 and the elastic roll plate 38.

[0055] Please see Figure 1 and Figure 2 The present invention provides an embodiment of a stretching and setting device for all-cotton four-way stretch fabric. An upper fabric frame 2 is connected to the left side of the stretching zone 1. Multiple sets of guide rollers are installed inside the upper fabric frame 2 to convey the stretching and setting fabric to the stretching zone 1. A heat setting box 3 is connected to the right side of the stretching zone 1. A steam conveying pipe is installed at the top of the heat setting box 3, and the other end of the steam conveying pipe is connected to the output end of a steam generator. A steam distribution conduit is installed inside the heat setting box 3, and the steam distribution conduit is connected to the steam conveying pipe. Steam nozzles are installed on the steam distribution conduit to evenly spray hot steam into the interior of the heat setting box 3. Multiple sets of support rollers are installed inside the heat setting box 3 to support the fabric to be processed.

[0056] Working principle: The fabric width and weft density data are set, and the fabric is woven according to the set data. The woven fabric is then mercerized, followed by air-jet alkali boiling. Afterward, a tenter frame is used to stretch and set the fabric. Based on the thickness of the fabric to be stretched and set, the distance between the two sets of tenter frames 15 is adjusted using adjustment component 14. According to the fabric width, servo motor 36 drives the take-up roller 37 to perform take-up or unwinding operations on the elastic plate 38. Simultaneously, telescopic rod 32 moves the moving seat 33, which in turn moves the take-up roller 37 horizontally towards or away from the I-beam 5. Furthermore, based on the thickness of the elastic plate 38 and the number of winding layers, telescopic rod 2 moves the support plate up and down synchronously to stretch the I-beam 5. The width of the fabric conveying area in the stretching zone 1, which is formed by the top of the plate 5 and the tops of the elastic roll plates 38 on both sides, is adjusted, and the position of the auxiliary transfer plate 6 is adjusted simultaneously so that the stretching assembly can adapt to fabrics of different widths. After the stretching zone 1 is adjusted, the fabric is transferred to the I-beam plate 5 through the upper fabric frame 2, and the two sides of the fabric are respectively located between the two sets of stretching frames 15. The stretching frames 15 rotate outward along the fabric surface to apply tension to the fabric, and the two sides of the fabric are fixed by the fixing blocks. While the fabric moves to the right along the surface of the I-beam plate 5, the stretching frames 15 move synchronously. The stretching frames 15 are used to stretch and shape the fabric. After stretching and shaping, the fabric continues to move to the right, so that the fabric moves into the heat setting box 3. Hot steam is introduced into the heat setting box to heat-shape the fabric.
