Description

Technical Field

[0001] This invention relates to the technical field of wool fabric drying and deformation prevention equipment, and particularly to wool fabric drying and deformation prevention equipment and its usage method. Background Technology

[0002] Wool fabric drying and anti-deformation equipment refers to specialized drying equipment designed for animal protein fiber fabrics such as wool, cashmere, and wool blends that are prone to shrinkage, stretching, and deformation. During the drying process, it controls parameters such as temperature, air volume, tension, and shrinkage to prevent abnormalities in the fabric's shape and size, such as shrinkage, elongation, wrinkling, uneven width, and hardening of the hand. This ensures that the fabric retains its original appearance, hand feel, and dimensional stability after drying.

[0003] A comfort fabric pre-shrinking device disclosed in Chinese invention patent application publication number CN220034961U, although the aforementioned device uses a telescopic rod and elastic element to press the stretching rollers against the fabric, and drives two stretching rollers to slide back and forth on the fabric through a driving element to stretch the fabric, allows the fabric to be fully and evenly moistened when humidified by steam from the first and second steam pipes after being squeezed and stretched, greatly improving the pre-shrinking effect, the aforementioned device neglects the fact that the air volume required for drying wool fabrics of different weights must be stable and adapted to the different weights of wool fabrics. Otherwise, it will affect the anti-deformation effect of the wool fabric during drying. The aforementioned device also... The previous application overlooked the fact that wool fabrics, even under normal airflow conditions, may still experience abnormal shrinkage and deformation during drying. If this is not detected and addressed in time, the finished product will be scrapped, resulting in economic losses for the factory. Furthermore, the aforementioned device uses a traditional fixed tension method to transport wool fabrics, which cannot adapt to the tension required by wool fabrics of different weights, making it less competitive in the market. Using the traditional fixed tension method to feed wool fabrics into the dryer may cause fiber damage, dimensional instability, wrinkling, and shrinkage due to high temperatures, affecting drying quality and finished product qualification rate. Therefore, this application provides a wool fabric drying and anti-deformation equipment and its usage method to meet the requirements. Summary of the Invention

[0014] The operating method of the wool fabric drying and deformation prevention equipment includes the following steps: Step 1: The wool fabric passes through the hollow trough and then enters the drying chamber for drying. The air intake module can automatically adjust the air volume according to the weight of the wool fabric, thus actively adapting to the air volume required for wool fabrics of different weights. It can also quickly trigger an alarm when the wool fabric undergoes abnormal shrinkage and deformation, reminding workers to stop the machine in time. The micro-tensioning module can control the degree of micro-tensioning of the wool fabric by adjusting the tensioning distance on the wool fabric and the weight pressed on the wool fabric during the tensioning process. The micro-tensioning process performs slight and controllable pre-tensioning of the fabric in advance, which can pre-compensate for the natural shrinkage of the fabric during the drying process, so that the fabric dries and rebounds in a low tension or zero tension state during the drying stage, and then the dried wool fabric can return to its normal state. The door can be opened and closed via hinges during later maintenance, allowing maintenance personnel to enter the drying chamber for inspections. The observation window allows workers to observe the drying process of the wool fabric inside the drying chamber from the outside. The wool fabric does not enter the drying chamber through an internal winding device; instead, there are winding and unwinding mechanisms before and after the drying process. Therefore, this device only performs drying and micro-tensioning operations on the wool fabric and does not perform winding operations. Step 2: Hot air is blown into the enclosed space consisting of a square box, a box cover, and a box bottom plate through the air inlet pipe. The wool fabric passes through the hollow groove plate and then drapes onto the follower roller. The follower roller itself has no rotational power; it only serves to support the wool fabric. However, after the wool fabric is draped onto the follower roller, the weight at the bottom of the strip plate increases. At this time, the elliptical spring connected to the strip plate cannot bear this weight, so the elliptical spring is stretched and deformed, causing the strip plate to gradually move downward from the strip groove. Of course, the stretching and deformation of the elliptical spring varies according to the weight of the wool fabric. Therefore, different weights of wool fabric will cause the strip plate to move downward a different distance, resulting in different gaps between the strip plate and the strip groove. Thus, the amount of hot air that can enter through the gap is proportional to the weight of the wool fabric. Therefore, this module can automatically adjust the air intake volume according to the weight of the wool fabric and ensure the stability of the air intake volume. After the wool fabric is initially placed on the follower roller, the strip plate has already fallen. Drying has not yet begun. At this point, the worker can enter the drying chamber and loosen the first connecting bolt, allowing the short cylinder to rotate. This causes the top of the threaded column, the abutment, to change from a downward-facing to an upward-facing position. The first connecting bolt is then screwed back in to secure the short cylinder. If the wool fabric undergoes significant deformation, it will change shape, reducing the weight at the bottom of the strip plate. This allows the elliptical spring to recover slightly, pulling the strip plate upwards. This, in turn, causes the abutment to move upwards, contacting the trigger button on the alarm unit. The alarm unit then emits a sharp sound. Upon hearing this sound, the worker must immediately stop the machine, as the wool fabric has already undergone significant deformation. The rechargeable battery is heat-resistant and provides power to the alarm unit. Step 3: The micro-tensioning module performs micro-tensioning on the wool fabric before it enters the drying chamber. This allows the wool fabric's shape to be slightly altered. Normally, wool fabric shrinks to some extent after drying. However, the micro-tensioning restores the wool fabric's shape, preventing further shrinkage and ensuring it retains its original form. This module uses a cylinder to drive a cylinder rod in reciprocating motion, which in turn moves a long block horizontally, thus horizontally tensioning the wool fabric. The vertical downward pressure on the wool fabric is controlled by adjusting the first, second, and third counterweights. Through the combined use of these two methods, the wool fabric is micro-tensioned, resulting in a larger initial shape. However, during drying, normal shrinkage occurs, and the wool fabric returns to its original normal shape. The track has a certain degree of inclination, but not a large one. This inclination allows the base block to slide actively towards the track sealing plate. When the long block is pushed to its limit position, the circular iron plate on the long block can be attracted to the cavity box by the strong magnetic force, thus keeping the circular soft plate away from the wool fabric and reducing friction with the wool fabric. When the long block is pulled back, the circular iron plate is still attracted, so the circular iron plate drives the base block to move towards the limiting block. When the base block hits the limiting block, it will stop moving, the circular iron plate will detach from the attraction, and the circular soft plate will fall back onto the wool fabric. At this time, the wool fabric can be micro-tensioned again.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, the adaptive air intake module can automatically adjust the air intake volume according to the weight of the wool fabric, thereby actively adapting to the air volume required for wool fabrics of different weights. This can reduce the possibility of fluctuating hot air volume to a certain extent, stabilize the air intake volume, and help improve the device's anti-deformation effect when drying wool fabrics.

[0016] By setting up an adaptive air intake module, this module can also quickly trigger an alarm when the wool fabric undergoes abnormal shrinkage and deformation, reminding workers to stop the machine in time. This can reduce the possibility of finished products being scrapped due to continuous production caused by fabric deformation, thereby reducing the factory's economic losses to a certain extent.

[0017] By setting up a micro-tensioning module, the degree of micro-tensioning of the wool fabric can be controlled by adjusting the tensioning distance and the weight pressed down on the wool fabric during the tensioning process. Compared with the traditional fixed tensioning method, this module has a higher adaptability to wool fabrics of different weights, which can enhance the market competitiveness of the device to a certain extent. At the same time, the slight and controllable pre-tensioning treatment of the fabric through micro-tensioning can pre-compensate for the natural shrinkage generated by the fabric during the drying process, so that the fabric can complete the drying and rebound in a low tension or zero tension state during the drying stage. This can reduce the possibility of fiber damage, dimensional instability, wrinkling and shrinkage caused by high temperature stretching in the traditional drying process, thereby improving the drying quality and the finished product qualification rate to a certain extent.

[0018] In summary, the present invention has the advantages of being able to actively adjust and stabilize the air intake, providing timely alarms to reduce economic losses when abnormal shrinkage and deformation occurs during the drying of wool fabrics, enhancing the market competitiveness of the device, and stabilizing drying quality and finished product qualification rate.

[0025] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0026] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0027] like Figures 1-2 As shown, embodiments of the present invention provide a wool fabric drying and anti-deformation device and a method of use, including a drying chamber 1, a hollow groove plate 2 fixedly connected to the inner wall of the drying chamber 1, an adaptive air inlet module 3 provided on the top of the drying chamber 1, a micro-tensioning module 4 fixedly connected to one side of the hollow groove plate 2, a side sealing plate 5 and a hinge 6 provided sequentially from left to right on the side of the drying chamber 1, an opening and closing door 7 installed in the drying chamber 1 through the hinge 6, a window groove opened on the front of the drying chamber 1, and an observation window 8 provided on the inner wall of the window groove.

[0028] Hollow trough plate 2 is welded to the inner wall of drying chamber 1, air inlet module 3 is welded to the top of drying chamber 1, micro-tensioning module 4 is welded to one side of hollow trough plate 2, side sealing plate 5 is welded to the left side of drying chamber 1, hinge 6 is installed between drying chamber 1 and opening / closing door 7, and observation window 8 is installed in window groove of drying chamber 1.

[0029] The wool fabric passes through the hollow trough plate 2 and then enters the drying chamber 1 for drying. The air inlet module 3 can automatically adjust the air volume according to the weight of the wool fabric, thus actively adapting to the air volume required for wool fabrics of different weights. It can also quickly trigger an alarm when the wool fabric undergoes abnormal shrinkage and deformation, reminding workers to stop the machine in time. The micro-tensioning module 4 can control the degree of micro-tensioning of the wool fabric by adjusting the tensioning distance on the wool fabric and the weight pressed on the wool fabric during the tensioning process. The micro-tensioning method can perform slight and controllable pre-tensioning treatment on the fabric in advance, which can pre-compensate for the natural shrinkage of the fabric during the drying process, so that the fabric can complete the drying and rebound in a low tension or zero tension state during the drying stage, and then the dried wool fabric can return to its normal state. The door 7 can be opened and closed via hinge 6 during later maintenance, allowing maintenance personnel to enter the drying chamber 1 for inspection. The observation window 8 allows workers to observe the drying process of the wool fabric in the drying chamber 1 from outside the device. The wool fabric does not enter the drying chamber 1 through a winding device inside the drying chamber 1, but rather through a winding mechanism before and after the drying process. Therefore, this device only performs drying and micro-tensioning operations on the wool fabric, and does not perform winding operations on the wool fabric.

[0030] like Figures 3-9 As shown, in this embodiment, the adaptable air inlet module 3 includes a square box 301. A box cover plate 302 is fixedly connected to the top of the square box 301. An air inlet pipe 303 is provided on the top of the box cover plate 302. A box bottom plate 304 is provided at the bottom of the square box 301. A strip groove is opened on the top of the box bottom plate 304. A vertical short plate 305 is fixedly connected to the top of the box bottom plate 304. A spring base plate 306 is fixedly connected to the front of the vertical short plate 305. An elliptical spring 307 is fixedly connected to the bottom of the spring base plate 306.

[0031] One end of the elliptical spring 307 is fixedly connected to a strip plate 308. The strip plate 308 and the strip groove are mutually adapted. A strip block 309 is fixedly connected to one side of the strip plate 308. A circular hole is opened on one side of the strip block 309. A first connecting threaded hole is opened on the front of the strip block 309. A first connecting bolt 310 is threadedly connected inside the first connecting threaded hole. A short cylinder 311 is threadedly connected to the strip block 309 through the first connecting bolt 310.

[0032] The short cylinder 311 and the circular hole are mutually compatible. One end of the short cylinder 311 is fixedly connected to a threaded ring 312. The threaded ring 312 is internally threaded to a threaded post 313. One end of the threaded post 313 is threaded to a bushing 314. The bottom of the strip plate 308 is fixedly connected to a vertical plate 315. The front of the vertical plate 315 has a pivot hole. The pivot hole contains a pivot 316. The pivot 316 contains a follower roller 317.

[0033] The bottom of the box base plate 304 is provided with an alarm body 318. The alarm body 318 is connected to the box base plate 304 by alarm bolts. The front of the alarm body 318 is provided with a sounder 319. A rechargeable battery 320 is provided on one side of the alarm body 318. A trigger button 321 is provided at the bottom of the alarm body 318.

[0034] The square box 301, box cover 302, and box bottom plate 304 are welded together. The air inlet pipe 303 is installed on the top of the box cover 302. The vertical short plate 305 is welded to the top of the box bottom plate 304. The spring base plate 306 is welded to the inner wall of the vertical short plate 305. The elliptical spring 307 is welded between the spring base plate 306 and the strip plate 308. The strip plate 308 is located in the strip groove of the box bottom plate 304. The strip block 309 is welded to the side of the strip plate 308. The short cylinder 311 is inserted into the circular hole of the strip block 309. The first connecting bolt 310 needs to be screwed into the strip. The first connecting threaded hole of the block 309 is fixed to the short cylinder 311. The threaded ring 312 is welded to the short cylinder 311. The threaded column 313 is screwed into the threaded ring 312. The abutment 314 is screwed to the top of the threaded column 313. The vertical plate 315 is welded to the bottom of the strip plate 308. The rotating shaft 316 is installed in the rotating shaft hole of the vertical plate 315. The follower roller 317 is inserted into the rotating shaft 316. The alarm body 318 is fixed to the bottom of the box bottom plate 304 by the alarm bolt. The rechargeable battery 320, the sounder 319, and the trigger button 321 are all integrally connected to the alarm body 318.

[0035] Hot air is blown into the enclosed space formed by the square box 301, the box cover 302, and the box bottom plate 304 through the air inlet pipe 303. Wool fabric passes through the hollow groove plate 2 and then drapes onto the follower roller 317. The follower roller 317 itself has no rotational power; it only serves to support the wool fabric. However, after the wool fabric drapes onto the follower roller 317, the weight at the bottom of the strip plate 308 increases. At this time, the elliptical spring 307 connected to the strip plate 308 cannot bear this weight, so the elliptical spring 307 is stretched. The change causes the strip plate 308 to gradually move downwards from the strip groove. Of course, the tensile deformation of the elliptical spring 307 varies according to the weight of the wool fabric. Therefore, different weights of wool fabric will cause the strip plate 308 to move downwards a different distance, resulting in different gaps between the strip plate 308 and the strip groove. Thus, the amount of hot air that can enter through the gap is proportional to the weight of the wool fabric. Therefore, this module can automatically adjust the air intake volume according to the weight of the wool fabric and ensure the stability of the air intake volume. After the wool fabric is initially placed on the follower roller 317, the strip plate 308 has already fallen. Drying has not yet begun. At this point, the worker can enter the drying chamber 1 and loosen the first connecting bolt 310, allowing the short cylinder 311 to rotate. This causes the top of the threaded column 313, i.e., the bushing 314, to change from a downward to an upward position. Then, the first connecting bolt 310 is screwed back in to secure the short cylinder 311. If the wool fabric undergoes significant deformation, the wool fabric will change, thus affecting the strip plate. The weight at the bottom of 308 is reduced, allowing the elliptical spring 307 to return to a slightly normal state, which in turn pulls the strip plate 308 upward, causing the retaining sleeve 314 to move upward as well, thus contacting the trigger button 321 on the alarm body 318. The alarm body 318 then emits a sharp sound through the buzzer 319. Once the worker hears the sound, they need to stop the machine immediately, because the wool fabric has already undergone significant deformation. The rechargeable battery 320 is heat-resistant and also provides power to the alarm body 318.

[0036] With the adaptive air intake module 3, the air intake can be automatically adjusted according to the weight of the wool fabric, thus actively adapting to the air volume required for wool fabrics of different weights. This can reduce the possibility of fluctuating hot air volume to a certain extent, stabilize the air intake volume, and help improve the device's anti-deformation effect when drying wool fabrics.

[0037] By setting up the adaptive air intake module 3, this module can also quickly trigger an alarm when the wool fabric undergoes abnormal shrinkage and deformation, reminding workers to stop the machine in time. This can reduce the possibility of finished product scrap due to continuous production caused by fabric deformation to a certain extent, thereby reducing the factory's economic losses to a certain extent.

[0043] The micro-tensioning module 4 is mainly used to perform micro-tensioning of the wool fabric before it enters the drying chamber 1, so that the shape of the wool fabric can be slightly changed. After entering the drying chamber 1, the normal wool fabric will shrink to a certain extent. At this time, the shape of the wool fabric after micro-tensioning will be restored, so that the wool fabric will not shrink after drying and can still maintain its original shape. This module drives the cylinder rod 405 to reciprocate through the cylinder 404, which in turn drives the long block 406 to move horizontally, thereby stretching the wool fabric horizontally. The vertical downward pressure of the module on the wool fabric is controlled by the increase or decrease of the first counterweight 411, the second counterweight 412 and the third counterweight 413. Through the combined use of the above two, the wool fabric can be micro-tensioned in shape. At this time, the shape of the wool fabric is larger, but during drying, due to normal shrinkage, the shape of the wool fabric will return to its original normal state. The track 417 has a certain degree of inclination, but the inclination is not very large. This inclination allows the base block 421 to slide actively towards the track sealing plate 425. When the long strip block 406 is pushed to the limit position, the circular iron plate 409 on the long strip block 406 can be attracted to the cavity box 422 by the magnetic force of the strong magnet 423, thereby making the circular soft plate 415 move away from the wool fabric and reduce friction with the wool fabric. When the long strip block 406 is pulled back, the circular iron plate 409 is still attracted, so the circular iron plate 409 drives the base block 421 to move towards the limiting block 419. When the base block 421 hits the limiting block 419, it will stop moving, the circular iron plate 409 will detach from the attraction, and the circular soft plate 415 will fall back onto the wool fabric. At this time, the wool fabric can be micro-tensioned again.

[0044] By setting up the micro-tensioning module 4, the degree of micro-tensioning of the wool fabric can be controlled by adjusting the tensioning distance on the wool fabric and the weight pressed down on the wool fabric during the tensioning process. Compared with the traditional fixed tensioning, this module has a higher adaptability to wool fabrics of different weights, which can enhance the market competitiveness of the device to a certain extent. At the same time, the slight and controllable pre-tensioning treatment of the fabric in advance through micro-tensioning can compensate for the natural shrinkage of the fabric during the drying process, so that the fabric can complete the drying and rebound in a low tension or zero tension state during the drying stage. This can reduce the possibility of fiber damage, dimensional instability, wrinkling and shrinkage caused by high temperature stretching in the traditional drying process to a certain extent, thereby improving the drying quality and the finished product qualification rate.

[0045] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0046] The operating method of the wool fabric drying and anti-deformation equipment includes the following steps; Step 1: The wool fabric passes through the hollow trough plate 2 and then enters the drying chamber 1 for drying. The air intake module 3 can automatically adjust the air intake according to the weight of the wool fabric, thus actively adapting to the air volume required for wool fabrics of different weights. It can also quickly trigger an alarm when the wool fabric undergoes abnormal shrinkage and deformation, reminding workers to stop the machine in time. The micro-tensioning module 4 can control the degree of micro-tensioning of the wool fabric by adjusting the tensioning distance on the wool fabric and the weight pressed on the wool fabric during the tensioning process. The micro-tensioning method can perform slight and controllable pre-tensioning treatment on the fabric in advance, which can pre-compensate for the natural shrinkage of the fabric during the drying process, so that the fabric can complete the drying and rebound in a low tension or zero tension state during the drying stage, and then the dried wool fabric can return to its normal state. The door 7 can be opened and closed via the hinge 6 during later maintenance, thus enabling maintenance personnel to enter the drying chamber 1 for maintenance. The observation window 8 allows workers to observe the drying process of the wool fabric in the drying chamber 1 from outside the device. The wool fabric does not enter the drying chamber 1 through a winding device inside the drying chamber 1, but rather through a winding mechanism before and after the drying process. Therefore, this device only performs drying and micro-tensioning operations on the wool fabric, and does not perform winding operations on the wool fabric. Step 2: Hot air is blown into the enclosed space formed by the square box 301, the box cover plate 302, and the box bottom plate 304 through the air inlet pipe 303. The wool fabric passes through the hollow groove plate 2 and then drapes onto the follower roller 317. The follower roller 317 itself has no rotational power; it only serves to support the wool fabric. However, after the wool fabric is draped onto the follower roller 317, the weight at the bottom of the strip plate 308 increases. At this time, the elliptical spring 307 connected to the strip plate 308 cannot bear the weight, so the elliptical spring 307 will be pulled. The stretching deformation causes the strip plate 308 to gradually move downwards from the strip groove. Of course, the stretching deformation of the elliptical spring 307 varies according to the weight of the wool fabric. Therefore, different weights of wool fabric will cause the strip plate 308 to move downwards a different distance, resulting in different gaps between the strip plate 308 and the strip groove. Thus, the amount of hot air that can enter through the gap is proportional to the weight of the wool fabric. Therefore, this module can automatically adjust the air intake volume according to the weight of the wool fabric and ensure the stability of the air intake volume. After the wool fabric is initially placed on the follower roller 317, the strip plate 308 has already fallen. Drying has not yet begun. At this point, the worker can enter the drying chamber 1 and loosen the first connecting bolt 310, allowing the short cylinder 311 to rotate. This causes the top of the threaded column 313, i.e., the bushing 314, to change from a downward to an upward position. Then, the first connecting bolt 310 is screwed back in to secure the short cylinder 311. If the wool fabric undergoes significant deformation, the wool fabric will change, thus affecting the strip plate. The weight at the bottom of 308 is reduced, which allows the elliptical spring 307 to return to a slightly normal state, thereby pulling the strip plate 308 upward. This, in turn, causes the bushing 314 to move upward as well, thus contacting the trigger button 321 on the alarm body 318. The alarm body 318 then emits a sharp sound through the buzzer 319. Once the worker hears the sound, they need to stop the machine immediately, because the wool fabric has already undergone significant deformation. The rechargeable battery 320 is heat-resistant and also provides power to the alarm body 318. Step 3: The micro-tensioning module 4 is mainly used to perform micro-tensioning of the wool fabric before it enters the drying chamber 1, so that the shape of the wool fabric can be slightly changed. After entering the drying chamber 1, the normal wool fabric will shrink to a certain extent. At this time, the shape of the wool fabric after micro-tensioning will be restored, so that the wool fabric will not shrink again after drying and can still maintain the original shape of the wool fabric. This module drives the cylinder rod 405 to reciprocate through the cylinder 404, which in turn drives the long block 406 to move horizontally, thereby stretching the wool fabric horizontally. The vertical downward pressure of the module on the wool fabric is controlled by the increase or decrease of the first counterweight 411, the second counterweight 412 and the third counterweight 413. Through the combined use of the above two, the wool fabric can be micro-tensioned in shape. At this time, the shape of the wool fabric is larger, but during drying, due to normal shrinkage, the shape of the wool fabric will return to its original normal state. The track 417 has a certain degree of inclination, but the inclination is not very large. This inclination allows the base block 421 to slide actively towards the track sealing plate 425. When the long strip block 406 is pushed to the limit position, the circular iron plate 409 on the long strip block 406 can be attracted to the cavity box 422 by the magnetic force of the strong magnet 423, thereby making the circular soft plate 415 move away from the wool fabric and reduce friction with the wool fabric. When the long strip block 406 is pulled back, the circular iron plate 409 is still attracted, so the circular iron plate 409 drives the base block 421 to move towards the limiting block 419. When the base block 421 hits the limiting block 419, it will stop moving, the circular iron plate 409 will detach from the attraction, and the circular soft plate 415 will fall back onto the wool fabric. At this time, the wool fabric can be micro-tensioned again.

[0047] The technical solution provided by this invention: Wool fabric passes through the hollow trough plate 2 and then enters the drying chamber 1 for drying. The adaptive air inlet module 3 can automatically adjust the airflow according to the weight of the wool fabric, thus actively adapting to the airflow required for wool fabrics of different weights. It can also quickly trigger an alarm when the wool fabric undergoes abnormal shrinkage or deformation, reminding workers to stop the machine immediately. The micro-tensioning module 4 can control the degree of micro-tensioning of the wool fabric by adjusting the tensioning distance and the weight pressed down on the wool fabric during the tensioning process, thus enabling pre-tensioning... The fabric undergoes a slight, controllable pre-tensioning treatment, which pre-compensates for the natural shrinkage that occurs during the drying process. This allows the fabric to dry and recover in a low-tension or zero-tension state during the drying stage, enabling the dried wool fabric to return to its normal state. The door 7 can be opened and closed via hinge 6 during later maintenance, allowing maintenance personnel to enter the drying chamber 1 for inspection. The observation window 8 allows workers to observe the drying process of the wool fabric inside the drying chamber 1 from outside the device. The wool fabric entering the drying chamber 1 does not necessarily indicate that the interior of the drying chamber 1 is dry. Instead of a winding device, a winding mechanism and an unwinding mechanism are set before and after the drying process, respectively. Therefore, this device only performs drying and micro-tensioning operations on wool fabrics, and does not perform winding operations on wool fabrics. Hot air is blown into the enclosed space formed by the square box 301, the box cover plate 302, and the box bottom plate 304 through the air inlet pipe 303. The wool fabric passes through the hollow groove plate 2 and then falls onto the follower roller 317. The follower roller 317 itself has no rotational power; it only serves to support the wool fabric. However, after the wool fabric falls onto the follower roller 317, the weight of the bottom of the strip plate 308 will increase. At this time, the weight of the strip plate 308 will increase. Because the connected elliptical spring 307 cannot withstand the weight, it will be stretched and deformed, causing the strip plate 308 to gradually move downward from the strip groove. Of course, the stretching deformation of the elliptical spring 307 varies according to the weight of the wool fabric. Therefore, different weights of wool fabric will cause the strip plate 308 to move downward a different distance, resulting in different gaps between the strip plate 308 and the strip groove. Thus, the amount of hot air that can enter through the gap is proportional to the weight of the wool fabric. Therefore, this module can automatically adjust the air intake volume according to the weight of the wool fabric.Furthermore, it ensures a stable airflow. After the wool fabric is initially placed on the follower roller 317, the strip plate 308 has already fallen. Drying has not yet begun. At this point, the worker can enter the drying chamber 1 and loosen the first connecting bolt 310, allowing the short cylinder 311 to rotate. This causes the top of the threaded column 313, i.e., the abutment 314, to change from a downward to an upward position. Then, the first connecting bolt 310 is screwed back in to fix the short cylinder 311. If the wool fabric undergoes significant deformation, the fabric will change, reducing the weight at the bottom of the strip plate 308. This allows the elliptical spring 307 to recover slightly, pulling the strip plate 308 upwards. The actuator 314 moves upwards, contacting the trigger button 321 on the alarm body 318. The alarm body 318 then emits a sharp sound through the buzzer 319. Upon hearing this, the worker must immediately stop the machine, as the wool fabric has already undergone significant deformation. The rechargeable battery 320 is heat-resistant and provides power to the alarm body 318. The micro-tensioning module 4 performs micro-tensioning before the wool fabric enters the drying chamber 1, subtly altering its shape. Normal wool fabric shrinks after drying in the chamber, but the micro-tensioned version restores its shape, preventing further shrinkage after drying. Despite the shrinkage and subsequent shape change, the original shape of the wool fabric can be maintained. This module uses cylinder 404 to drive cylinder rod 405 in reciprocating motion, which in turn drives the long block 406 in horizontal movement, thus horizontally tensioning the wool fabric. The vertical downward pressure on the wool fabric is controlled by adjusting the weights 411, 412, and 413. Through the combined use of these two methods, the wool fabric can be slightly tensioned, resulting in a larger shape. However, during drying, normal shrinkage will cause the wool fabric to return to its original normal shape. The track 417 has a certain degree of inclination, but the inclination is not significant. The incline allows the base block 421 to slide actively towards the track sealing plate 425. When the long block 406 is pushed to its limit position, the circular iron plate 409 on the long block 406 can be attracted to the cavity box 422 by the magnetic force of the strong magnet 423, thereby keeping the circular flexible plate 415 away from the wool fabric and reducing friction with the wool fabric. When the long block 406 is pulled back, the circular iron plate 409 is still attracted, so the circular iron plate 409 drives the base block 421 to move towards the limiting block 419. When the base block 421 hits the limiting block 419, it will stop moving, the circular iron plate 409 will detach from the attraction, and the circular flexible plate 415 will fall back onto the wool fabric, at which point the micro-tensioning operation on the wool fabric can be performed again.

10. The method of using the wool fabric drying and anti-deformation equipment according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1: The wool fabric will pass through the hollow slot plate (2) and then enter the drying chamber (1) for drying. The air inlet module (3) can automatically adjust the air volume according to the weight of the wool fabric, so as to actively adapt to the air volume required by the wool fabric under different weights. It can also quickly trigger an alarm when the wool fabric undergoes abnormal shrinkage and deformation, reminding the workers to stop the machine in time. The micro-tensioning module (4) can control the degree of micro-tensioning of the wool fabric by adjusting the distance of tensioning on the wool fabric and the weight pressed on the wool fabric during the tensioning process. The fabric can be slightly and controllably pre-tensioned by micro-tensioning in advance, which can compensate for the natural shrinkage of the fabric during the drying process, so that the fabric can complete the drying and rebound in a low tension or zero tension state during the drying stage, and then the dried wool fabric can return to the normal state. The door (7) can be opened and closed by the hinge (6) during later maintenance, thereby enabling the door (7) to be opened and closed, and allowing maintenance personnel to enter the drying chamber (1) for maintenance. The observation window (8) allows workers to observe the drying of wool fabric in the drying chamber (1) from outside the device. The wool fabric does not enter the drying chamber (1) because there is a winding device inside the drying chamber (1). Instead, there are winding and unwinding mechanisms before and after the drying process. Therefore, the device only performs drying and micro-tensioning operations on the wool fabric and does not perform winding operations on the wool fabric. Step 2: Hot air is blown into the enclosed space formed by the square box (301), the box cover plate (302), and the box bottom plate (304) through the air inlet pipe (303). The wool fabric passes through the hollow groove plate (2) and then falls onto the follower roller (317). The follower roller (317) itself has no rotational power; it only serves to support the wool fabric. However, after the wool fabric falls onto the follower roller (317), the weight at the bottom of the strip plate (308) will increase. At this time, the elliptical spring (307) connected to the strip plate (308) cannot bear the weight, so the elliptical spring (307) 307) will be stretched and deformed, which will cause the strip plate (308) to gradually move downward from the strip groove. Of course, the stretching deformation of the elliptical spring (307) varies according to the weight of the wool fabric. Therefore, different weights of wool fabric will cause the strip plate (308) to move downward a different distance, and thus the gap between the strip plate (308) and the strip groove will also be different. Therefore, the amount of hot air that can enter through the gap is proportional to the weight of the wool fabric. Therefore, this module can automatically adjust the air intake according to the weight of the wool fabric and ensure the stability of the air intake. After the wool fabric is initially placed on the follower roller (317), the strip plate (308) has already fallen. Drying has not yet begun. At this point, the worker can enter the drying chamber (1) and loosen the first connecting bolt (310), allowing the short cylinder (311) to rotate. This causes the top of the threaded column (313), i.e., the bushing (314), to change from a downward to an upward position. Then, the first connecting bolt (310) is screwed back in to fix the short cylinder (311). If the wool fabric undergoes significant deformation, the wool fabric will change, thus affecting the strip plate ( The weight at the bottom of 308 is reduced, which allows the elliptical spring (307) to recover a little, thereby pulling the strip plate (308) upward, which in turn drives the bushing (314) upward, thereby contacting the trigger button (321) on the alarm body (318). The alarm body (318) emits a sharp sound through the sounder (319). The worker needs to stop the machine immediately after hearing the sound, because the wool fabric has already undergone a relatively serious deformation. The rechargeable battery (320) can withstand high temperatures and also provides power support for the alarm body (318). Step 3, the micro-tensioning module (4) mainly performs micro-tensioning operations before the wool fabric enters the drying chamber (1), so that the shape of the wool fabric can be slightly changed. After entering the drying chamber (1) for drying, the normal wool fabric will shrink to a certain extent. At this time, the shape of the wool fabric after micro-tensioning will be restored, so that the wool fabric will not shrink after drying and can still maintain the original shape of the wool fabric. The module drives the cylinder rod (405) to reciprocate through the cylinder (404), thereby driving the long block (406) to move horizontally, and then stretches the wool fabric horizontally. The module controls the vertical downward pressure of the wool fabric by increasing or decreasing the first counterweight (411), the second counterweight (412) and the third counterweight (413). Through the combined use of the above two, the wool fabric can be micro-tensioned in shape. At this time, the shape of the wool fabric is larger, but during drying, because there will be normal shrinkage, the shape of the wool fabric will return to its original normal state. The track (417) has a certain degree of inclination, but the inclination is not very large. This inclination allows the base block (421) to slide actively towards the track sealing plate (425). When the long block (406) is pushed to its limit position, the circular iron plate (409) on the long block (406) can be attracted to the cavity box (422) by the magnetic force of the strong magnet (423), thereby making the circular soft plate (415) away from the wool fabric and reducing contact with the wool fabric. Friction occurs when the long strip (406) is pulled back. At this time, the circular iron plate (409) is still attracted. Therefore, the circular iron plate (409) drives the base block (421) to move towards the limiting block (419). When the base block (421) hits the limiting block (419), it will stop moving. The circular iron plate (409) will then be removed from the attraction, and the circular soft plate (415) will fall back onto the wool fabric. At this time, the wool fabric can be micro-tensioned again.
