Description

Technical Field

[0001] This invention relates to the field of textile dyeing and finishing technology, and in particular to a stretching device and stretching method based on textile dyeing and finishing technology. Background Technology

[0002] In the fabric textile processing, after the preceding processes such as weaving and dyeing, the fabric is prone to problems such as width shrinkage, weft skew, and surface unevenness due to the release of internal stress in the yarns and uneven processing tension. These problems directly affect the accuracy of subsequent cutting, sewing, and other processes and the appearance of the finished product. Tensioning stretches the fabric width to a preset standard size and keeps it stable. At the same time, it corrects weft skew and eliminates wrinkles, making the warp and weft yarns of the fabric neatly arranged, improving the flatness and dimensional stability of the fabric surface, and ensuring that the fabric is not prone to deformation or shrinkage in subsequent processing and finished product use, thus ensuring the processing adaptability and final quality of the textile.

[0003] Existing tenter assemblies used in fabric textile processing typically have fixed tenter clamps with limited adjustment range. This significantly restricts the effective tenter working width, making them suitable only for small fabrics. When dealing with longer fabrics, the structural limitations of the equipment often force operators to either fold the fabric before tentering or cut it into smaller segments and then tenter them one by one. These methods not only easily damage the fabric's integrity due to folding, compression, and cutting, but also result in uneven stress at folds and inconsistent tension across segments during tentering. Consequently, the overall dimensional stability of the stretched fabric is insufficient, and the fabric surface flatness is inconsistent, ultimately affecting the tentering effect and the fabric's suitability for subsequent use. This results in poor flexibility and limited practicality. Summary of the Invention

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please refer to Figures 1 to 11 Example 1:

[0038] This invention proposes a tenter frame and a tenter frame method based on textile dyeing and finishing technology, including: an inlet assembly 1 and a tenter frame assembly; the inlet assembly 1 includes an installation platform 101, a retainer 102, a fixing block 103 and an electric push rod 104, the retainer 102 is inserted into the top of the installation platform 101, the fixing block 103 is inserted into the inside of the retainer 102, the electric push rod 104 is fixedly installed on the top of the retainer 102, and the bottom end of the push rod of the electric push rod 104 is fixedly installed on the top of the fixing block 103; the tenter frame assembly consists of a drive mechanism 2, a transmission mechanism 3 and a take-up roller 4.

[0039] The drive mechanism 2 includes a mounting base 201, a drive motor 202, and a drive rod 203. The mounting base 201 is fixedly mounted on the side of the mounting platform 101, and the drive motor 202 is fixedly mounted on the side of the mounting base 201. The drive rod 203 is rotatably connected inside the mounting base 201. The transmission mechanism 3 includes a flexible drive shaft 301, a positioning plate 302, a force application seat 303, and a direct drive shaft 304. The flexible drive shaft 301 is rotatably connected inside the mounting base 201, and the positioning plate 302 is inserted into the flexible drive shaft 301. The force application seat 303 is inserted into the flexible drive shaft 301, and the direct drive shaft 304 is rotatably connected to the side of the mounting base 201. The take-up roller 4 is detachably fixedly mounted on the outside of the direct drive shaft 304.

[0040] The flexible drive shaft 301 and the direct drive shaft 304 are connected by a gear set. In use, the drive mechanism 2 can drive the take-up roller 4 to rotate through the transmission mechanism 3. The rotation of the take-up roller 4 realizes the winding and stretching of the fabric. It is flexible and convenient to use. After the fabric passes through the retainer 102 from the bottom of the fixed pressure block 103, and then the end of the fabric passing through the retainer 102 is fixed on the take-up roller 4, the winding or stretching operation can be performed as needed. The drive motor 202 has a drive worm 2021 on the outside of its rotating shaft, and the drive rod 203 has a transmission worm wheel 2031 on the outside of its drive rod. The drive worm 2021 and the transmission worm wheel 2031 are connected by transmission. The flexible drive shaft 301 can only rotate unidirectionally inside the mounting base 201. The drive motor 202 drives the fabric when it rotates. The worm gear 2021 can drive the drive rod 203 to rotate through the transmission worm wheel 2031. When the drive rod 203 rotates, the transmission rod 2032 can drive the force-applying seat 303 to rotate through the transmission groove 3034. When the fixed pressure block 103 does not press and fix the fabric, the resistance of the take-up roller 4 to the fabric is less than the elastic force of the force-applying top spring 3031. At this time, the force-receiving protrusion 3011 is located inside the pressure-increasing groove 3032 at one end away from the circulation groove 3033. Therefore, when the force-applying seat 303 rotates, the pressure-increasing groove 3032 can drive the flexible drive shaft 301 to rotate through the force-receiving protrusion 3011. When the flexible drive shaft 301 rotates, it can drive the direct drive shaft 304 to rotate through the gear set. When the direct drive shaft 304 rotates, it can drive the take-up roller 4 to rotate synchronously, thereby realizing the take-up operation of the fabric. It is convenient and flexible to use.

[0041] The drive rod 203 has a transmission rod 2032 with a regular polygonal cross-section on its side, and the force application seat 303 has a transmission groove 3034 inside. The transmission rod 2032 is inserted into the transmission groove 3034. In use, when stretching the fabric, it is only necessary to periodically control the extension and retraction of the electric push rod 104 during the fabric winding process. When the electric push rod 104 retracts, the fixing block 103 will not press the fabric tightly, and the fabric can be smoothly wound through the inside of the retainer 102. When the electric push rod 104 extends, it will drive the fixing block 103 to move down and press and position the fabric, so that subsequent fabric can be wound without... The fabric continues to pass through the retainer 102, and the fabric that has passed through the retainer 102 will be stretched under the action of the stretching assembly, thereby realizing the stretching operation of the fabric. After the fabric is pressed and positioned by the fixing block 103, the rotation ability of the take-up roller 4 and the direct drive shaft 304 is limited under the traction of the fabric. That is, neither the take-up roller 4 nor the direct drive shaft 304 can continue to rotate freely in the take-up direction. Thus, the rotation of the direct drive shaft 304 also restricts the rotation of the flexible drive shaft 301. Afterwards, when the drive motor 202 continues to rotate, it can provide stretching force to the transmission mechanism 3 and the take-up roller 4 to perform the stretching operation of the fabric.

[0042] The force-applying seat 303 has a force-applying top spring 3031 on its side, with both ends of the force-applying top spring 3031 abutting against the side of the force-applying seat 303 and the side of the positioning plate 302, respectively. The force-applying seat 303 has a tension control groove on its exterior, and the flexible drive shaft 301 has a force-receiving protrusion 3011 inside. The force-receiving protrusion 3011 is inserted into the tension control groove. The tension control groove consists of a spiral-shaped pressure-increasing groove 3032 and an annular circulation groove 3033. One end of the pressure-increasing groove 3032 is connected to the groove body of the circulation groove 3033. In use, when the fabric is pressed and positioned by the fixing block 103, and the drive motor 202 continues to rotate, due to the flexible... The rotation of the drive shaft 301 is restricted. At this time, under the rotation of the drive rod 203, the force-applying seat 303 and the force-bearing protrusion 3011 move towards the circulation groove 3033 inside the pressure-increasing groove 3032. This causes the force-applying seat 303 to move to one side inside the flexible drive shaft 301 to avoid and compress the force-applying top spring 3031. Even after compression, the force-applying top spring 3031 can still provide a force to the flexible drive shaft 301 to rotate the direct drive shaft 304 in the winding direction through the cooperation of the pressure-increasing groove 3032 and the force-bearing protrusion 3011. This force, acting on the take-up roller 4, provides a stretching effect to the fabric. Because the drive rod 203 and... The drive motors 202 are connected via a drive worm gear 2021 and a transmission worm wheel 2031. The worm gear has a unidirectional transmission characteristic, ensuring that the drive rod 203 will not reverse during the rotation of the drive motor 202, preventing the tensioning effect from disappearing and ensuring stable operation. Subsequently, the force-bearing protrusion 3011 enters the circulation groove 3033 to accommodate the continuous rotation of the drive motor 202, preventing jamming. Furthermore, since the flexible drive shaft 301 can only rotate unidirectionally within the mounting base 201, even after the force-bearing protrusion 3011 enters the circulation groove 3033, the flexible drive shaft 301 will not reverse. This leads to the failure of the stretching effect and function, further improving the stability of the device. Moreover, each time the force-bearing protrusion 3011 passes through the connection position of the circulation groove 3033 and the pressure groove 3032, it will continue to provide a stretching effect for the fabric. Through the periodic contraction of the electric push rod 104, the continuous stretching processing operation of the fabric can be realized. There is no need to fold or cut the fabric. It is possible to perform an integrated and complete stretching operation on long fabrics. Furthermore, by controlling the speed of the drive motor 202 and the extension and retraction cycle of the electric push rod 104, the stretching time and stretching cycle of the fabric in the stretching section can be adjusted, which is highly flexible and adaptable.

[0043] The import component 1 includes a positioning screw 105, which is rotatably connected inside the mounting platform 101 and screwed onto the bottom of the retainer 102 via a threaded rod. The transmission mechanism 3 includes an adjusting ring 305, which is rotatably connected to the outside of the flexible drive shaft 301. A threaded block 3021 is provided on the outside of the positioning disc 302, and the threaded block 3021 and the adjusting ring 305 are threadedly engaged. In use, the positioning screw 105 can adjust the length of the fabric in the stretching section (between the retainer 102 and the take-up roller 4). When the positioning screw 105 is rotated, it can drive the retainer via the threaded rod. The position of the retainer 102 is changed, which alters the distance between the retainer 102 and the take-up roller 4, thus changing the length of the fabric in the stretching section. The adjusting ring 305 can adjust the maximum stretching force when the fabric is stretched. When the adjusting ring 305 is rotated, it can drive the positioning plate 302 to move and change its position through the threaded block 3021. The change in the position of the positioning plate 302 changes the initial compression length of the force-applying top spring 3031, thus changing the maximum stretching force it can provide when stretching the fabric. The adjustment is convenient and flexible, and it can adapt to the stretching processing operation of fabrics of different specifications and types, further improving its flexibility and adaptability.

[0044] The specific usage and function of this embodiment: In this invention, according to processing requirements, the length of the fabric in the stretching section and the stretching force, etc., are adjusted. The positioning screw 105 can control the length of the fabric in the stretching section (between the retainer 102 and the take-up roller 4). When the positioning screw 105 is rotated, the positioning screw 105 can drive the retainer 102 to move and change its position through the screw thread. The change in the position of the retainer 102 changes the distance between the retainer 102 and the take-up roller 4, that is, the length of the fabric in the stretching section. The adjusting ring 305 can adjust the maximum stretching force when the fabric is stretched. When the adjusting ring 305 is rotated, the adjusting ring 305 can drive the positioning disc 302 to move and change its position through the threaded block 3021. 2. Changing the position of use alters the initial compression length of the force-applying top spring 3031, thus changing the maximum stretching force it can provide for fabric stretching. This adapts to stretching operations on fabrics of different specifications and types. After adjustment, winding or stretching operations can begin. The drive mechanism 2 drives the take-up roller 4 to rotate via the transmission mechanism 3, thereby achieving fabric winding and stretching operations through the rotation of the take-up roller 4. It is flexible and convenient to use. After passing the fabric through the retainer 102 from the bottom of the fixed pressure block 103, and then fixing one end of the fabric through the retainer 102 onto the take-up roller 4, winding or stretching operations can be performed as needed. When the drive motor 202 rotates, the drive worm 2021 can drive the drive worm gear 2031 to drive the drive worm wheel 2021. When the drive rod 203 rotates, the transmission rod 2032 can drive the force-applying seat 303 to rotate through the transmission groove 3034. When the fixed pressure block 103 does not press and fix the fabric, the resistance of the take-up roller 4 to the fabric is less than the elastic force of the force-applying top spring 3031. At this time, the force-bearing protrusion 3011 is located inside the pressure-increasing groove 3032 at one end away from the circulation groove 3033. Therefore, when the force-applying seat 303 rotates, the pressure-increasing groove 3032 can drive the flexible drive shaft 301 to rotate through the force-bearing protrusion 3011. When the flexible drive shaft 301 rotates, it can drive the direct drive shaft 304 to rotate through the gear set. When the direct drive shaft 304 rotates, it can drive the take-up roller 4 to rotate synchronously, thereby realizing the take-up operation of the fabric. When stretching the fabric, it is only necessary to... During the fabric winding process, the electric push rod 104 is periodically extended and retracted. When the electric push rod 104 retracts, the fixed pressure block 103 does not press the fabric tightly, allowing the fabric to pass smoothly through the inside of the retainer 102 and be wound up. When the electric push rod 104 extends, it drives the fixed pressure block 103 to move down and press the fabric into position, preventing subsequent fabric from passing through the retainer 102. The fabric that has already passed through the retainer 102 is then stretched by the stretching assembly, thus achieving the stretching process. Once the fabric is pressed and positioned by the fixed pressure block 103, the rotational capacity of the take-up roller 4 and the direct drive shaft 304 is limited due to the fabric's tension; that is, neither the take-up roller 4 nor the direct drive shaft 304 can continue to rotate freely in the winding direction.Therefore, the direct drive shaft 304 restricts the rotation of the flexible drive shaft 301. When the drive motor 202 continues to rotate, it provides tensioning force to the transmission mechanism 3 and the take-up roller 4, performing tensioning operations on the fabric. After the fabric is pressed and positioned by the fixing block 103, when the drive motor 202 continues to rotate, due to the restricted rotation of the flexible drive shaft 301, the force-applying seat 303, under the rotation of the drive rod 203, will have its force-bearing protrusion 3011 move towards the circulation groove 303 within the pressure-increasing groove 3032, thereby causing the force-applying seat... 303 will move to one side inside the flexible drive shaft 301 to avoid and compress the force-applying top spring 3031. After being compressed, the force-applying top spring 3031 can still provide a force to the flexible drive shaft 301 to rotate the direct drive shaft 304 in the winding direction through the cooperation of the pressure groove 3032 and the force-receiving protrusion 3011. This force, when applied to the take-up roller 4, can provide a stretching effect for the fabric. Since the drive rod 203 and the drive motor 202 are connected by the drive worm 2021 and the transmission worm gear 2031, the worm gear has the characteristic of unidirectional transmission. This ensures that the drive rod 203 will not reverse during the rotation of the drive motor 202, preventing the tensioning effect from disappearing and ensuring stable operation. Subsequently, the force-bearing protrusion 3011 will enter the circulation groove 3033 to accommodate the continuous rotation of the drive motor 202, preventing jamming. Furthermore, since the flexible drive shaft 301 can only rotate unidirectionally within the mounting base 201, even after the force-bearing protrusion 3011 enters the circulation groove 3033, the flexible drive shaft 301 will not reverse, preventing the tensioning effect from failing, further improving performance. The device is stable, and each time the force-bearing protrusion 3011 passes the connection point of the circulation groove 3033 and the pressure-boosting groove 3032, it continues to provide a stretching effect to the fabric. Through the periodic contraction and retraction of the electric push rod 104, continuous stretching processing of the fabric can be achieved. This eliminates the need to fold or cut the fabric, enabling integrated and complete stretching of long fabrics. Furthermore, by controlling the speed of the drive motor 202 and the extension / retraction cycle of the electric push rod 104, parameters such as the stretching duration and stretching cycle of the fabric in the stretching section can be adjusted.

When the electric push rod (104) retracts, the fixed pressure block (103) will not press the fixed fabric. At this time, the fabric can be smoothly wound through the inside of the retainer (102). When the electric push rod (104) extends, it will drive the fixed pressure block (103) to move down and press the fabric to position, so that the subsequent fabric cannot continue to pass through the retainer (102). Thus, the fabric that has passed through the retainer (102) will be stretched under the action of the stretching component, thereby realizing the stretching processing operation of the fabric. ⑤. By controlling the speed of the drive motor (202) and the extension and retraction cycle of the electric push rod (104), the stretching time of the fabric in the stretching section and the stretching cycle parameters of the fabric can be adjusted.
