Description

Technical Field

[0001] This utility model belongs to the field of chemical fiber processing technology, and specifically relates to a chemical fiber filament warping equipment with an automated tension adjustment mechanism. Background Technology

[0002] Warping is a key process in the production of filament fabrics. It refers to winding a certain number of warp yarns parallel to a warp beam or weaving beam according to a specified length and width. During the process, it is required that the tension of each warp yarn is equal, the distribution is uniform, and the arrangement of colored yarns conforms to the process specifications. This directly affects the subsequent weaving quality. To ensure the quality of warping, warping machines commonly used in the production of filament fabrics are usually equipped with tension adjustment mechanisms.

[0003] Traditional tension adjustment mechanisms typically adjust filament tension by changing the distance between two sets of tension rollers. This method requires a large amount of internal space for movement, resulting in increased equipment size, which not only increases production costs but also increases the space occupied by the equipment. Chinese patent with publication number "CN117328183A" discloses a chemical fiber filament warping device with an automated tension adjustment mechanism. It adjusts tension through a tension assembly, monitors the filament tension value in real time by a tension detector, controls a motor to drive a threaded rod to rotate, and causes the threaded ring to move the arc plate to change the distance between the arc plates, thereby adjusting the filament tension and reducing the risk of filament breakage.

[0004] However, the device still has defects and shortcomings in application. Although its tension adjustment structure does not require vertical extension, it still expands and contracts in essence by driving the lead screw of the motor to move the arc plate. It still requires a certain amount of space to move during use. At the same time, the structure is relatively complex and lacks a buffer structure. When the instantaneous tension of the filament is too large, it cannot effectively buffer the impact force, which can easily lead to the breakage of the chemical fiber filament. It can be seen that the existing technology still needs to be improved and perfected. Utility Model Content

This allows the instantaneous tension of the filament to be controlled within the tolerance range during use, achieving automated closed-loop tension adjustment. This reduces the risk of filament breakage and improves adjustment accuracy, solving the problems of easy filament breakage and low adjustment accuracy in existing technologies with no buffer design.

[0025] refer to Figures 1 to 5 This embodiment of a chemical fiber filament warping device with an automated tension adjustment mechanism 3 includes a warping device main frame 1, base frames 2 are fixedly installed on both sides of the top of the warping device main frame 1, guide rollers 4 are rotatably connected to the upper part of the base frames 2, and tension adjustment mechanism 3 is fixedly installed in the middle of the top of the base frames 2.

[0026] The tension adjustment mechanism 3 includes a concave frame 31, which is fixedly installed at the top center of the base frame 2. A tension adjustment component 32 is fixedly installed at the top of the concave frame 31, and an adjustment component 33 is fixedly installed on one side of the concave frame 31. Tension detection components 34 are fixedly installed at the front end of each adjustment component 33, with the detection ends of the tension detection components 34 located on both sides of the tension adjustment components 32. During operation, the main frame 1 of the warping equipment provides the installation foundation, the guide rollers 4 on the base frame 2 guide the transmission of chemical fiber filaments, the concave frame 31 of the tension adjustment mechanism 3 is fixed to the top of the base frame 2, and the tension adjustment component 32 is responsible for adjusting the filament tension. The tension detection component 34 can be adjusted by the section component 33 so that the detection end is on both sides of the tension adjustment component 32 to monitor the filament tension. During operation, the filament enters the tension adjustment component 32 through the guide roller 4. The tension detection component 34 detects the tension in real time, and the adjustment component 33 adjusts the detection position as needed to ensure accurate detection. During the entire use, all components are integrated into the concave frame 31, which has a compact structure, reduces space occupation, and solves the problem of large size of traditional equipment. Through the cooperation of the tension detection component 34 and the tension adjustment component 32, automated tension adjustment is realized, the adjustment accuracy is improved, and it can adapt to the tension detection needs under different working conditions to ensure the quality of warping.

[0027] refer to Figures 1-5The tension adjustment assembly 32 includes a fixed plate 321, which is fixedly installed at both ends of the top of the concave frame 31. Connecting frames 322 are rotatably connected to the top and bottom of the inner side of the fixed plate 321. A tension module 323 is fixedly installed between the inner sides of the connecting frames 322. A first motor 324 is fixedly connected to the outer side of one fixed plate 321. The output end of the first motor 324 is fixedly connected to the outer side of one connecting frame 322. The tension module 323 includes a fixed block 3231. Buffer springs 3232 are fixedly installed in a ring at equal intervals on the outer side of the fixed block 3231. A fixed ring 3233 is fixedly installed on the outer side of the buffer springs 3232. A connecting frame 3234 is fixedly installed on the inner side of the fixed ring 3233. A tension adjusting roller 3235 is fixedly installed on the inner side of the connecting frame 3234. During application, the fixed plate 321 is fixed to the concave frame. At the top two ends of 31, the connecting frame 322 is rotatably connected to the top and bottom of the inner side of the fixed plate 321, respectively. The tension module 323 is fixed between the two connecting frames 322. When the first motor 324 starts, its output end drives the connecting frame 322 to rotate around the fixed plate 321. The connecting frame 322 drives the tension module 323 to move synchronously, so that the tension adjusting roller 3235 contacts the filament and forms a squeezing force to adjust the tension. In the tension module 323, the buffer spring 3232 on the outside of the fixed block 3231 is connected to the fixed ring 3233. When the filament tension is too high instantaneously, the buffer spring 3232 deforms to absorb the impact force. It drives the connecting frame 322 to rotate through the first motor 324 to adjust the tension. There is no need for large extension and retraction of the parts, saving space. The buffer spring 3232 can buffer instantaneous tension and reduce the risk of filament breakage. The overall structure has good linkage and can accurately adjust the tension, improving the warping quality.

[0028] refer to Figures 3-4The adjusting component 33 includes a fixing frame 331, which is fixedly installed on the back of the concave frame 31. A guide rail 332 is fixedly installed on the back of the fixing frame 331. A second motor 333 is fixedly installed on the top of the guide rail 332. A lead screw 334 is fixedly installed through the guide rail 332 at the output end of the second motor 333. A slider 335 is threadedly connected to the outer surface of the lead screw 334 and slidably connected to the inside of the guide rail 332. The tension detection component 34 is fixedly installed on the back of the slider 335. The tension detection component 34 includes a connecting rod 341, which is fixedly installed on the back of the slider 335. Bending frames 342 are fixedly installed at both ends of the top of the connecting rod 341. A pressure sensor 343 is fixedly installed at the front end of the bending frame 342. A mounting frame 344 is fixedly connected to the bottom detection end of the pressure sensor 343. A detection pressure roller 345 is rotatably connected inside the mounting frame 344. During application, the fixed frame 331 is fixed to the back of the concave frame 31, and the guide rail 332 is installed on the back of the fixed frame 331. After the second motor 333 starts, its output end drives the lead screw 334 to rotate. Because the slider 335 is threadedly connected to the lead screw 334 and slides in the guide rail 332, the slider 335 will drive the tension detection component 34 to move along the guide rail 332. In the tension detection component 34, the connecting rod 341 is fixed to the back of the slider 335. The pressure sensor 343 at the front end of the bending frame 342 is connected to the detection pressure roller 345 through the mounting frame 344. The detection pressure roller 345 contacts the filament, and the pressure sensor 343 converts the tension into a signal feedback. Its adjustment component 33 can flexibly adjust the detection position to adapt to different filament specifications. The pressure sensor 343 detects the tension in real time, providing accurate basis for adjustment. The overall structure is compact and easy to operate, improving the automation and accuracy of tension adjustment and reducing manual intervention.

[0029] refer to Figures 1-2Support legs 5 are fixedly installed at the four corners of the bottom of the main frame 1 of the warping equipment. A base plate 6 is fixedly installed at the bottom of each support leg 5. Limiting discs 7 are fixedly installed at both ends of the guide rollers 4 and the tension adjusting rollers 3235. During operation, the support legs 5 at the four corners of the bottom of the main frame 1 of the warping equipment provide overall support, raising the main frame to a suitable operating height. The base plate 6 increases the contact area with the ground, distributing the weight of the equipment, enhancing its stability, and reducing the impact of equipment vibration on the tension during warping. The limiting discs 7 at both ends of the guide roller 4 and the tension adjusting roller 3235 form a barrier along the transverse direction of the filament during filament transmission and tension adjustment, restricting the filament from shifting to both sides and ensuring that the filament is always transmitted and stressed within the preset path. Its advantages are that the support leg 5 and the base plate 6 work together to improve the overall stability of the equipment and provide a foundation for the precise operation of each component; the limiting discs 7 effectively prevent filament deviation, avoid uneven tension caused by filament deviation, ensure warping quality, and have a simple structure that can adapt to the transmission needs of filaments of different specifications.

[0030] Operating Principle and Advantages: During operation, this device is first fixed to the work site by the support legs 5 and base plate 6 at the bottom of the main frame 1 of the warping equipment. The support legs 5 raise the equipment to a suitable operating height, and the base plate 6 increases the contact area with the ground, together providing a stable foundation for the entire equipment and preventing vibration from affecting the tension adjustment accuracy during operation. After the chemical fiber filaments are drawn out from the unwinding device, they are transmitted through the guide rollers 4 at the upper end of the base frame 2. The limiting discs 7 at both ends of the guide rollers 4 block the filaments laterally, limiting the filaments from shifting during transmission and ensuring stability. The filament enters the tension adjustment mechanism 3 precisely along a preset path. Then, the adjustment component 33 starts operating, and the output of the second motor 333 drives the lead screw 334 to rotate inside the guide rail 332. Since the slider 335 is threadedly connected to the lead screw 334 and limited by the guide rail 332, the slider 335 moves linearly along the guide rail 332, thereby driving the tension detection component 34 fixed to the back of the slider 335 to move synchronously until the detection pressure roller 345 contacts the filament surface, and the contact pressure meets the detection requirements. Subsequently, the first motor of the tension adjustment component 32... When machine 324 starts, its output drives the connecting frame 322 to rotate around the fixed disk 321. The connecting frame 322 drives the buffer module and the inner tension adjusting roller 3235 to rotate synchronously. The two tension adjusting rollers 3235 change their contact angle with the filament through relative rotation, forming a stable extrusion force on the chemical fiber filament, thereby establishing an initial tension support state. During the warping process, the filament continuously passes between the two tension adjusting rollers 3235. The pressure sensor 343 of the tension detection component 34 senses the tension change of the filament in real time through the detection pressure roller 345 and converts it into... For electrical signal feedback, when an abnormal tension is detected, the first motor 324 adjusts the rotation angle of the connecting frame 322 according to the feedback signal, and changes the squeezing force of the tension regulating roller 3235 on the filament to achieve dynamic tension adjustment; if the filament experiences a tension peak momentarily, the buffer spring 3232 in the tension module 323 will undergo elastic deformation, absorbing part of the impact force through its own extension and contraction, reducing the instantaneous stress on the filament. At the same time, the guide roller 4 continuously guides the filament to stable transmission. All components work together to always maintain the filament tension within the process setting range.

[0031] The tension adjustment mechanism 3 used in this device specifically solves the problems of volume and space in traditional equipment. Traditional tension adjustment mechanisms 3 mostly adjust tension by changing the spacing between components or the extension range, which requires a large amount of space to move inside the equipment, resulting in a large overall size of the equipment. However, the tension adjustment component 32 of this equipment adjusts the tension by rotating the tension adjustment roller 3235 through the connecting frame 322 to change the extrusion pressure. During the adjustment process, each component only rotates within the fixed area of ​​the main frame 1 of the warping equipment, without the need for additional extension space. Combined with the design of the slider 335 in the adjustment component 33 moving compactly along the guide rail 332, the installation and operating space required by the equipment is greatly reduced, making the equipment structure more compact and reducing the space requirements of the production site.

[0032] Meanwhile, this device effectively solves the problem of filament breakage caused by excessive instantaneous tension. Existing technologies lack a buffer structure, making filaments prone to breakage when subjected to instantaneous tension impacts. However, the buffer spring 3232 in the tension module 323 of this device can absorb part of the impact force through elastic deformation, controlling the instantaneous tension on the filament within a tolerable range, significantly reducing the risk of filament breakage and overcoming the shortcomings of existing technologies with no buffer design. Furthermore, the device significantly improves the accuracy and automation of tension adjustment. The tension detection component 34 monitors the filament tension in real time through the pressure sensor 343 and feeds back the data. The first motor 324 precisely adjusts the rotation angle of the tension adjusting roller 3235 based on the data, achieving automated closed-loop tension adjustment. The adjustment accuracy is far higher than traditional manual or mechanical adjustment methods. The adjustment component 33 can be adjusted via the slider 3... The flexible adjustment of the contact position between the detection pressure roller 345 and the filament allows for adaptation to the detection needs of chemical fiber filaments of different diameters and materials. The limiting discs 7 at both ends of the guide roller 4 and the tension adjusting roller 3235 effectively prevent lateral deviation of the filament, avoiding uneven tension caused by filament deviation. The support leg 5 and the base plate 6 together enhance the stability of the equipment operation and reduce the interference of vibration on tension adjustment. The fixed frame 331 provides a stable installation base for the adjustment component 33, while the guide rail 332 ensures the accurate movement trajectory of the slider 335 and guarantees the positioning accuracy of the tension detection component 34. The connecting rod 341, through a reasonable structural design, enables the pressure sensor 343 to detect the filament tension at the optimal angle. All structures cooperate and work together to comprehensively improve the stability and reliability of the warping process, effectively ensuring the quality and production efficiency of filament warping.

[0033] The support leg 5 has a height of 800-1200mm, and the base plate 6 has dimensions of 300mm×300mm×10mm; the guide roller 4 and tension adjusting roller 3235 both have a diameter of 50-100mm and a length of 500-1500mm; the limit plate 7 has a diameter 20-50mm larger than the corresponding roller body; the first motor 324 and the second motor 333 both use servo motors of model 60ST-M00630, with a rated power of 1.5kW and a rated speed of 3000r / min; pressure sensor 343 uses a strain gauge sensor of model PT124G-111, with a measurement range of 0-500N and an output signal of 4-20mA; the controller is a PLC of model S7-1200, which is installed on the outer side of the back of the concave frame 31 and is connected to the first motor 324, the second motor 333 and the pressure sensor 343 through wires respectively. The power supply is AC220V power supply converted to DC24V by a transformer to power the controller and the sensor, and the motor is directly connected to AC380V power supply.
