[0025] In the related art, the impregnated industrial fabric 300 is a relatively thick synthetic fiber fabric, which is made into a cloth shaft by a loom and is produced by a impregnation process on an impregnation device.

[0026] During the dipping process, when the unwinding machine completes unwinding, the unwinding machine and the front traction machine stop operating, while the remaining equipment continues to operate normally at the original speed. The unwinding machine changes its shaft and fabric splices, and the fabric storage rack needs to have sufficient material to ensure that there is still material left in the storage rack after the unwinding machine completes the shaft and fabric splicing process. Often, during this process, the fabric storage rack has difficulty dynamically adjusting the fabric tension. Due to changes in fabric length or external interference, the fabric can easily sag or overstretch, causing deformation, wrinkles, or damage, affecting product quality.

[0027] like Figure 1 and Figure 2 As shown, in order to solve the above technical problems, the embodiment of the present application provides a cloth storage rack 500, which includes an upper cloth guide roller assembly 530, a lower cloth guide roller assembly 540 and an adjustment assembly. The upper cloth guide roller assembly 530 is located above the lower cloth guide roller assembly. The upper cloth guide roller assembly 530 has at least one upper cloth guide roller 531, and the lower cloth guide roller assembly 540 has a connecting mechanism and at least one lower cloth guide roller 541. The upper cloth guide roller 531 and the lower cloth guide roller 541 are used to guide and support the cloth 300; The adjusting component and the connecting mechanism of the lower cloth guide roller assembly 540 are connected and arranged, and the adjusting component can drive the lower cloth guide roller assembly 540 to move in a preset direction with a preset driving force, and the preset direction has at least a component along the vertical direction, so that the movement of the lower cloth guide roller assembly 540 can adjust the distance between the upper cloth guide roller assembly 530 and the lower cloth guide roller assembly 540; wherein, the resultant force of the preset driving force, the gravity of the lower cloth guide roller assembly and the tension of the cloth 300 is zero.

[0028] In these embodiments, the cloth storage rack 500 provided in this application is a new technical solution, which aims to solve the problem of difficulty in dynamically adjusting the tension of the cloth 300 during the dipping process. The following is a detailed description of this technical solution: The upper cloth guide roller assembly 530 is located above the lower cloth guide roller assembly 540 and includes at least one upper cloth guide roller 531. For example, in this embodiment, the number of upper cloth guide rollers 531 is 19. Of course, in other embodiments, the number of upper cloth guide rollers 531 may also be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, or 16, etc.

[0029] The lower cloth guide roller assembly 540 includes not only at least one lower cloth guide roller 541 but also a connection mechanism for connecting to the adjustment assembly. For example, in this embodiment, there are 18 lower cloth guide rollers 541. Of course, in other embodiments, the number of lower cloth guide rollers 541 may also be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, or 16, etc.

[0030] When there are multiple upper cloth guide rollers 531 and multiple lower cloth guide rollers 541, the cloth storage rack 500 has an arrangement direction, and the multiple lower cloth guide rollers 541 and the multiple upper cloth guide rollers 531 are arranged at intervals along the arrangement direction. For example, the arrangement direction and the preset direction are arranged perpendicularly, for example, the arrangement direction is set to the horizontal direction and the preset direction is the vertical direction.

[0031] It should be noted that the main function of the upper cloth guide roller 531 and the lower cloth guide roller 541 is to guide and support the cloth 300, ensuring that it passes smoothly through the cloth storage rack 500. In other words, the starting end of the cloth 300 is drawn out from the unwinding device of the unwinding machine 100 and first enters the lower cloth guide roller assembly 540 of the cloth storage rack 500. The winding of the lower cloth guide roller assembly 540 is as follows: After entering the starting point, the fabric 300 is first wound around the first upper fabric roller 531 of the upper fabric roller assembly 530. The fabric 300 then passes over the first upper fabric roller 531 and then extends downward to below the first lower fabric roller 541. After being wound around the first lower fabric roller 541, the fabric 300 again extends upward to below the second upper fabric roller 531. This continues in an S-shaped pattern around the lower and upper fabric rollers 541, 531, ensuring full contact between the fabric 300 and each lower and upper fabric roller 541, 531, for evenly distributed tension. After exiting the last upper fabric roller 531 of the upper fabric roller assembly 530, the fabric 300 enters subsequent dipping equipment, such as the front haul-off machine 200 or a dipping tank.

[0032] The adjustment assembly is connected to the connection mechanism of the lower cloth guide roller assembly 540. The adjustment assembly is capable of driving the lower cloth guide roller assembly 540 in a predetermined direction (including at least a vertical component) using a predetermined driving force. In this embodiment, the predetermined direction is vertical, and the upper cloth guide roller assembly 530 and the lower cloth guide roller assembly 540 are spaced apart in the vertical direction. This movement adjusts the distance between the upper cloth guide roller assembly 530 and the lower cloth guide roller assembly 540, thereby achieving precise control of the tension of the cloth 300.

[0033] It should be noted that one of the key points is that the combined force of the preset driving force, the weight of the lower cloth guide roller assembly, and the tension of the cloth 300 is zero. By achieving a balance between the preset driving force applied by the adjustment component, the weight of the lower cloth guide roller assembly, and the tension of the cloth 300, the cloth 300 maintains a constant tension throughout the entire processing process, avoiding problems such as slack or excessive stretching.

[0034] Therefore, during the dipping process, when the unwinding machine 100 completes unwinding and stops operating, the cloth storage rack 500 dynamically adjusts the position of the lower cloth guide roller assembly 540 via the adjustment assembly. Based on changes in the tension of the cloth 300, the adjustment assembly maintains a preset driving force on the lower cloth guide roller assembly 540, driving the lower cloth guide roller assembly 540 to move vertically, thereby adjusting the distance between the upper and lower cloth guide roller assemblies 530 and 540. In this way, the tension of the cloth 300 is maintained constant, preventing the cloth 300 from slacking or overstretching, thereby ensuring product quality. In other words, by driving the lower cloth guide roller assembly 540 via the adjustment assembly, the tension of the cloth 300 can be adjusted in real time, preventing the cloth 300 from slacking or overstretching. Maintaining constant tension on the cloth 300 reduces deformation, wrinkling, or damage, thereby improving product quality.

[0035] Furthermore, it should be noted that the speed of the dipping machine is generally around 40 m / min, and the cloth storage rack 500 generally stores approximately 180 meters of cloth. This insufficient cloth storage capacity cannot meet the high-speed operation requirements. Clearly, by adjusting the distance between the lower cloth guide roller assembly 540 and the upper cloth guide roller assembly 530 using the adjustment assembly, the cloth storage rack 500 can increase its cloth storage length. This means that while the equipment occupies the same floor space, more cloth can be stored, meeting the high-speed operation requirements of the dipping machine.

[0036] Furthermore, this fabric storage rack 500 is of great significance for improving the quality and efficiency of the dipping process, and is particularly suitable for industrial scenarios requiring high-precision fabric 300 processing. It provides an effective solution to the challenges posed by the length variation of fabric 300, ensuring a smoother and more efficient production process.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments, the cloth storage rack 500 further includes a main frame 550, an upper cloth guide roller assembly 530 is disposed at the upper portion of the main frame 550, and a lower cloth guide roller assembly 540 is located at the lower portion of the main frame 550. Under the action of an adjustment assembly, the lower cloth guide roller assembly 540 can move relative to the upper cloth guide roller assembly 530 to adjust the distance between the lower cloth guide roller assembly 540 and the upper cloth guide roller assembly 530. The adjustment assembly can also be disposed on the main frame 550.

[0038] In addition, the main frame 550 is respectively provided with a feed guide roller 400 and a discharge guide roller 600 at both ends of the arrangement direction. The cloth 300 first passes around the lower side of the feed guide roller 400, and then passes around the upper side of the upper cloth guide roller 531 and the lower side of the lower cloth guide roller 541 in turn.

[0039] In some embodiments, the adjustment component includes a chain transmission mechanism 510 and a driving mechanism 520, the chain transmission mechanism 510 has a driving sprocket 511 and a transmission chain 512, the driving mechanism 520 is connected to the driving sprocket 511, the driving mechanism 520 is used to drive the driving sprocket 511 to rotate, the transmission chain 512 has a tight edge, the tight edge is parallel to the preset direction, and the tight edge is connected to the connecting mechanism.

[0040] In these embodiments, the adjustment assembly is further refined to specifically include a chain transmission mechanism 510 and a driving mechanism 520. This allows for more precise control of the movement of the lower cloth guide roller assembly 540, thereby achieving dynamic adjustment of the tension of the cloth 300.

[0041] The chain transmission mechanism 510 includes a driving sprocket 511 , a driven sprocket 513 and a transmission chain 512 . The transmission chain 512 is annular and sleeved on the driving sprocket 511 and the driven sprocket 513 . The transmission chain 512 is meshed with the driving sprocket 511 and the driven sprocket 513 , respectively.

[0042] The transmission chain 512 meshes with the driving sprocket 511 and has a tight side and a loose side. The tight side refers to the portion of the chain that is in a taut state when transmitting power. The drive mechanism 520 is connected to the driving sprocket 511 to provide driving force to rotate the driving sprocket 511.

[0043] For example, in this embodiment, the driving sprocket 511 and the driven sprocket 513 are of the same specifications, and the driving sprocket 511 and the driven sprocket 513 are spaced apart in the preset direction. Of course, in other embodiments, the driving sprocket 511 and the driven sprocket 513 are of different specifications, as long as the tight side is parallel to the preset direction.

[0044] Exemplarily, the driving mechanism 520 includes an electric motor, a hydraulic motor or other forms of power source, and a suitable type is selected according to actual needs. In this embodiment, the driving mechanism 520 is configured as a servo motor.

[0045] For example, in this embodiment, the drive mechanism 520 includes a servo motor and a transmission system. The number of chain transmission mechanisms is four, and the servo motor is connected to the driving sprockets 511 of the four chain transmission mechanisms 510 through the transmission mechanism to drive them to rotate. The transmission system can be a worm gear transmission system, a gear transmission system, or the like.

[0046] The tight side of the transmission chain 512 is parallel to the preset direction and is directly connected to the connection mechanism of the lower cloth guide roller assembly 540. When the driving mechanism 520 drives the driving sprocket 511 to rotate, the tight side of the transmission chain 512 pulls or pushes the lower cloth guide roller assembly 540, causing it to move in the preset direction (at least with a vertical component).

[0047] When the drive mechanism 520 starts and drives the driving sprocket 511 to rotate, the transmission chain 512 moves accordingly. Because the tight edge of the transmission chain 512 is connected to the connecting mechanism of the lower cloth guide roller assembly 540, the movement of the chain drives the lower cloth guide roller assembly 540 to move up and down. By controlling the speed and direction of the drive mechanism 520, the position of the lower cloth guide roller assembly 540 can be precisely adjusted, thereby adjusting the distance between the upper cloth guide roller assembly 530 and the lower cloth guide roller assembly 540. This ensures that the combined force of the preset driving force, the gravity of the lower cloth guide roller assembly, and the tension of the cloth 300 is zero, thereby maintaining a constant tension in the cloth 300. Furthermore, the cloth storage capacity of the cloth storage rack 500 can be adjusted.

[0048] like Figure 7 and Figure 8 As shown, in some embodiments, the transmission chain 512 includes a chain body, an adapter 5121 and a pair of adjusting members, the chain body has two free ends, a pair of adjusting members are arranged on the adapter 5121, each free end is connected to an adjusting member, and the adjusting member is used to adjust the distance between the corresponding free end and the adapter 5121 in a preset direction.

[0049] In these embodiments, the chain body is the main part of the transmission chain 512, generally composed of multiple links, and has two free ends. The free ends refer to the two ends of the chain body, that is, the unfixed or unconnected parts.

[0050] The adapter 5121 is a component that connects the free end of the chain body and is used to connect the transmission chain 512 to other mechanical components (such as the lower frame 542). At the same time, the adapter 5121 is provided with a pair of adjustment members.

[0051] The adjusting member is a component used to adjust the distance between the free end of the chain and the adapter 5121. Each free end is connected to an adjusting member, and the adjusting member is used to fine-tune the distance between the free end and the adapter 5121 in a preset direction.

[0052] In other words, each free end of the chain is connected to an adapter 5121. The adapter 5121 is connected to the free ends of the chain via an adjustment member. The adjustment member is mounted on the adapter 5121 and is used to adjust the distance between the free ends of the chain and the adapter 5121. Each free end corresponds to an adjustment member, and the adjustment members can be operated independently to achieve precise control of the tension of the transmission chain 512.

[0053] Furthermore, the distance between the free end and the adapter 5121 is adjusted by the adjusting member, and the multiple chain transmission mechanisms 510 are used to adjust the horizontal state of the lower cloth guide roller assembly 540, that is, to ensure the horizontal state of the lower cloth guide roller 541, which is conducive to controlling the tension of the cloth 300.

[0054] The adjusting member can change the tension of the chain by adjusting the distance between the free end of the chain and the adapter 5121. This adjustment can ensure that the chain maintains appropriate tension during transmission, preventing the chain from being too loose or too tight, thereby reducing wear and noise.

[0055] In addition, since the lower cloth guide roller assembly 540 has gravity, the gravity of the lower cloth guide roller assembly 540 acts on the transmission chain 512, thereby maintaining the tension of the transmission chain 512 and facilitating the synchronization of the lifting and lowering of the lower cloth guide roller assembly 540. In addition, since the transmission chain 512 is a flexible transmission member, it can play a buffering role.

[0056] In other words, the transmission chain 512, as a flexible transmission element, can absorb external shock and vibration to a certain extent. This allows the system to better adapt and maintain stable operation when faced with changes in the length of the fabric 300 or other external disturbances. The presence of the flexible chain reduces the rigid impact caused by rigid connections, protects equipment components, and extends their service life.

[0057] During actual production, fabric 300 may experience momentary stretching or relaxation for various reasons. The flexible chain cushions these changes through its elastic deformation, allowing the system to quickly return to normal operation. This cushioning effect not only improves system stability but also reduces damage to fabric 300 caused by sudden tension changes, further enhancing product quality.

[0058] like Figure 8 As shown, in some embodiments, the adjusting member includes a base 5122, a connecting rod 5123 and at least two locking nuts 5124, the base 5122 has an adjustment hole arranged therethrough, the adjustment hole extends along a preset direction, the base 5122 is arranged on the adapter 5121, the connecting rod 5123 has a fixed end and a threaded end, the fixed end is connected to the free end, the threaded end is passed through the adjustment hole, and the parts of the threaded end located at both ends of the adjustment hole are respectively threadedly connected with at least one locking nut 5124, and the locking nut 5124 is abutted against the base 5122.

[0059] In these embodiments, the adjustment member provides more precise fine-tuning and locking functions. Specifically, the adjustment member includes a base 5122, a connecting rod 5123, and at least two locking nuts 5124. This design allows for precise adjustment of the distance between the free end of the chain and the adapter 5121, and the locking nuts 5124 secure the position, ensuring the stability and reliability of the system.

[0060] The base 5122 has an adjustment hole extending therethrough, which extends in a predetermined direction (at least with a vertical component). The base 5122 is mounted on the adapter 5121, providing a fixed reference point for adjustment. For example, the base 5122 and the adapter 5121 are fixedly connected. For example, the base 5122 and the adapter 5121 are integrally arranged, or the base 5122 and the adapter 5121 are fixedly connected by welding, etc. Of course, the base 5122 is provided at each end of the adapter 5121 to form a U-shaped structure.

[0061] The connecting rod 5123 includes a fixed end and a threaded end. The fixed end is connected to the free end of the chain body. The threaded end passes through the adjustment hole on the base 5122 and is threadedly connected to at least one locking nut 5124 at each end.

[0062] Each locking nut 5124 abuts against the base 5122 to fix the position of the connecting rod 5123. By tightening or loosening the locking nut 5124, the position of the connecting rod 5123 in the adjustment hole can be accurately adjusted, thereby changing the distance between the free end of the chain and the adapter 5121.

[0063] For ease of understanding, the base 5122 is fixed to the adapter 5121 to ensure that the adjustment hole is correctly arranged along the preset direction. The fixed end of the connecting rod 5123 is connected to the free end of the chain body, and the threaded end passes through the adjustment hole of the base 5122. Loosen the locking nut 5124 to allow the connecting rod 5123 to move freely in the adjustment hole. Adjust the position of the connecting rod 5123 as needed to change the distance between the free end of the chain and the adapter 5121. For example, when the height of the lower cloth guide roller assembly 540 needs to be increased, the length of the tight side of the chain body can be shortened; vice versa. After adjusting to the appropriate position, tighten the locking nut 5124 so that it abuts against the base 5122, thereby fixing the connecting rod 5123 in the desired position.

[0064] Among them, the number of locking nuts 5124 can be set according to actual needs. Usually, there are at least two locking nuts 5124, one located on one side of the adjustment hole and the other located on the other side to ensure that the connecting rod 5123 is firmly fixed on the base 5122.

[0065] For example, in other embodiments, the adjustment hole on the base 5122 can also be set as a threaded hole, and the threaded end of the connecting rod can be threadedly connected to the threaded hole. Of course, to further ensure stability, a locking nut 5124 can also be installed on the threaded end, and the locking nut 5124 can abut against the base 5122 to achieve locking.

[0066] like Figure 4As shown, in some embodiments, the upper cloth guide roller assembly 530 also includes an upper frame 532 and at least one tension detection mechanism 570, at least one upper cloth guide roller 531 is arranged on the upper frame 532, and among the at least one upper cloth guide roller 531, one of the upper cloth guide rollers is connected to the upper frame 532 through the tension detection mechanism 570, and the tension detection mechanism 570 is used to obtain the tension carried by the corresponding upper cloth guide roller 531.

[0067] In these embodiments, the upper cloth guide roller assembly 530 is further equipped with a tension detection mechanism 570 to achieve real-time monitoring and feedback of the tension of the cloth 300. This design can significantly improve the automation level and response speed of the system, ensuring that the tension of the cloth 300 remains constant throughout the production process.

[0068] The upper frame 532 provides a stable framework for mounting and supporting at least one upper cloth guide roller 531. These upper cloth guide rollers 531 are mounted on the upper frame 532 to guide and support the cloth 300. Among the at least one upper cloth guide roller 531, one is connected to the upper frame 532 via a tension detection mechanism 570. For example, a second upper cloth guide roller 531 is connected to the upper frame 532 via a tension detection mechanism 570. Of course, in other embodiments, other upper cloth guide rollers 531 may also be connected to the upper frame 532 via a tension detection mechanism 570. The tension detection mechanism 570 is used to detect the tension of the cloth 300 carried by the corresponding upper cloth guide roller 531 and transmit the data to the control system for processing.

[0069] As the fabric 300 passes over the upper fabric guide roller 531, the tension detection mechanism 570 monitors the tension of the fabric 300 on the upper fabric guide roller in real time. The tension detection mechanism 570 typically uses a sensor (such as a strain gauge or pressure sensor) to measure the force exerted by the fabric 300 on the upper fabric guide roller and converts it into an electrical signal.

[0070] The sensor transmits the collected tension data to the control system. The control system analyzes the received data and adjusts the working state of the regulating component as needed to maintain constant tension of the cloth 300.

[0071] If the control system detects that the tension of the fabric 300 exceeds the set range, it issues a command to move the lower fabric guide roller assembly 540 via the adjustment component, thereby adjusting the distance between the upper and lower fabric guide roller assemblies 540 and restoring the fabric 300 tension to the set value. This closed-loop control mechanism can quickly respond to and adapt to various changes in the production process, ensuring that the fabric 300 tension remains stable.

[0072] Apparently, the tension detection mechanism 570 is capable of monitoring the tension of the fabric 300 in real time, providing accurate data support, enabling the system to react immediately and avoid product quality issues caused by tension fluctuations. By integrating the tension detection mechanism 570 with the control system, automated adjustment of the fabric 300 tension is achieved, reducing the need for manual intervention and improving production efficiency and product quality. Constant fabric 300 tension helps reduce problems such as deformation and wrinkling of the fabric 300, ensuring the consistency and stability of the final product quality. Furthermore, the system can quickly respond to changes in the length of the fabric 300 or other external disturbances by adjusting the distance between the upper and lower fabric guide roller assemblies 540 in real time, ensuring the continuity and stability of the production line.

[0073] For example, during the dipping process, the design of the upper cloth guide roller assembly 530 with a tension detection mechanism 570 can effectively address the difficulty in dynamically adjusting the tension of the cloth 300. For example, during the process of replacing the shaft and cloth end joint of the guide machine 100, the tension detection mechanism 570 can monitor the changes in the tension of the cloth 300 in real time and adjust the position of the lower cloth guide roller assembly 540 in a timely manner through the adjustment component to maintain constant tension of the cloth 300, avoid slack or overstretching, and thus improve the quality of the final product.

[0074] If, for some reason, the fabric 300 suddenly slackens during the process of replacing the shaft and cloth joint in the weaving machine 100, the tension detection mechanism 570 will immediately detect the tension drop and transmit a signal to the control system. The control system then issues a command to drive the lower fabric guide roller assembly 540 upward through the adjustment component, shortening the distance between the upper and lower fabric guide roller assemblies 540 and increasing the tension of the fabric 300 to restore it to the set value. The entire process is rapid and accurate, ensuring smooth operation of the production line and consistent product quality.

[0075] In summary, the design of the upper cloth guide roller assembly 530 with the tension detection mechanism 570 not only improves the automation level and response speed of the cloth storage rack 500 system, but also significantly enhances its ability to adapt to different production conditions, providing a strong guarantee for the stable operation of the dipping process production line.

[0076] In some embodiments, the cloth storage rack 500 further includes a control component, which is electrically connected to the tension detection mechanism 570 and the adjustment component respectively. The control component is used to send control instructions to the adjustment component according to the tension obtained by the tension detection mechanism 570 to adjust the preset driving force.

[0077] In these embodiments, the cloth storage rack 500 also includes a control component, which is electrically connected to the tension detection mechanism 570 and the adjustment component. The system can implement automated closed-loop control and dynamically adjust the preset driving force according to the tension of the cloth 300 monitored in real time, thereby maintaining the constant tension of the cloth 300.

[0078] The control component is the "brain" of the entire system, responsible for receiving, processing, and sending instructions. The control component is electrically connected to the tension detection mechanism 570 and the adjustment component, forming a closed-loop control system. The tension detection mechanism 570 is used to monitor the tension of the fabric 300 on the upper fabric guide roller 531 in real time and transmit the data to the control component. During the process of replacing the shaft and the cloth head joint of the guide machine 100, the adjustment component drives the lower fabric guide roller assembly 540 in a preset direction according to the instructions issued by the control component to adjust the distance between the upper and lower fabric guide roller assemblies 540, thereby changing the tension of the fabric 300.

[0079] The tension detection mechanism 570 monitors the tension of the cloth 300 on the upper cloth guide roller 531 in real time and converts the tension data into electrical signals. These signals are transmitted to the control component for processing. After receiving the tension data, the control component analyzes it and determines whether the current tension of the cloth 300 is within the set range.

[0080] If the tension exceeds the set range (too high or too low), the control component calculates the required driving force value based on a pre-set algorithm. Based on the calculated result, the control component sends a control command to the adjustment component, instructing it to adjust the preset driving force. Upon receiving the command, the adjustment component drives the lower cloth guide roller assembly 540 via a drive mechanism 520 (e.g., a servo motor), adjusting the distance between the upper and lower cloth guide roller assemblies 540 and thereby changing the tension of the fabric 300. The tension detection mechanism 570 continues to monitor the tension of the fabric 300 in real time and feeds the updated tension data back to the control component. Based on this feedback, the control component further fine-tunes the operating state of the adjustment component to ensure that the tension of the fabric 300 remains within the set range.

[0081] For example, when processing a single type of cloth 300, the tension of the cloth 300 is fixed. In other words, by keeping the preset driving force unchanged, the resultant force of the preset driving force, the tension of the cloth 300, and the gravity of the lower cloth guide roller assembly 540 can be zero and remain unchanged.

[0082] like Figure 5 and Figure 6As shown, in some embodiments, the lower cloth guide roller assembly 540 includes a lower frame 542, at least one cloth guide roller is arranged on the lower frame 542, and a limiting portion 543 is provided at the bottom of the lower frame 542, and the limiting portion 543 extends downward; when the limiting portion 543 is in contact with the ground, the adjusting member is located above the driven sprocket 513 of the chain transmission mechanism 510, and a gap is formed between the adjusting member and the driven sprocket 513.

[0083] In these embodiments, the lower frame 542 provides a stable frame structure for mounting and supporting at least one lower cloth guide roller 541. The lower cloth guide roller 541 is disposed on the lower frame 542 to guide and support the cloth 300. A limit portion 543 is disposed at the bottom of the lower frame 542. The limit portion 543 extends downward and is typically a physical limit device that prevents the lower frame 542 from descending excessively. The adjustment member is located above the driven sprocket 513 of the chain drive mechanism 510, and when the limit portion 543 is in contact with the ground, a gap is formed between the adjustment member and the driven sprocket 513.

[0084] This design ensures that the adjusting member will not collide or interfere with the driven sprocket 513 when in the extreme position, thereby protecting the safe operation of the equipment.

[0085] During normal operation, the spacing between the upper and lower cloth guide roller assemblies 540 is dynamically adjusted based on changes in the tension of the fabric 300. The drive mechanism 520 drives the lower cloth guide roller assembly 540 in a predetermined direction via a chain drive mechanism 510 (comprising a driving sprocket 511, a driven sprocket 513, and a transmission chain 512) to maintain constant tension on the fabric 300.

[0086] When the upper frame 532 needs to drop to the lowest position for some reason, the limiting portion 543 can first contact the ground. At this time, the limiting portion 543 plays a physical restriction effect, preventing the lower frame from continuing to descend, avoiding damage to the equipment.

[0087] For example, the limiting portion 543 includes at least one limiting rod. In practical applications, the number of the limiting rods can be 1, 2, 3, 4, 5, 6, 7, 8 or 9, etc.

[0088] In some embodiments, the cloth storage rack 500 also includes a limit assembly, which includes a pair of limit sensors. The lower frame 542 has a trigger part, and limit sensors are respectively provided at both ends of the moving path of the trigger part, and the trigger part is located between the pair of limit sensors. The limit sensor is used to obtain the position information of the trigger part.

[0089] In these embodiments, the cloth storage rack 500 is further equipped with a limit assembly, which includes a pair of limit sensors and a trigger unit. This design can achieve precise control of the movement range of the lower cloth guide roller assembly 540, preventing it from exceeding the safe range, thereby ensuring the safety and stability of the system.

[0090] The limit assembly consists of a pair of limit sensors and a trigger unit. The limit sensors detect the position of the trigger unit and transmit the data to the control system.

[0091] The lower frame 542 provides a support structure and is equipped with at least one lower cloth guide roller 541. The triggering unit is fixed to the lower frame 542 and moves with the movement of the lower cloth guide roller assembly 540. For example, the triggering unit can be the entire lower frame 542 or a portion of the lower frame 542, which is not specifically limited here.

[0092] A limit sensor is provided at each end of the moving path of the lower cloth guide roller assembly 540. The trigger is located between the pair of limit sensors to ensure that it can be monitored throughout its entire range of movement.

[0093] When the lower cloth guide roller assembly 540 moves in a predetermined direction (typically including a vertical component), the trigger unit also moves. A limit sensor monitors the position of the trigger unit in real time and transmits this information to the control system. The control system analyzes the data received from the limit sensor and determines whether the trigger unit is approaching or has reached its limit position.

[0094] If the trigger unit approaches or reaches its limit position, the control system issues a command to halt further movement of the adjustment assembly, preventing the lower cloth guide roller assembly 540 from exceeding a safe range. During normal operation, the control system adjusts the operating state of the adjustment assembly based on data from the tension detection mechanism 570 to maintain constant tension on the fabric 300. If the limit sensor detects that the trigger unit is approaching its limit position, the control system immediately takes action to prevent equipment damage or malfunction.

[0095] For example, in this embodiment, the limit sensor is a travel switch. Of course, in other embodiments, the limit sensor can also be a laser limit sensor, a capacitive limit sensor, a magnetic limit sensor, or a photoelectric limit sensor, etc.

[0096] like Figure 3 and Figure 4As shown, in some embodiments, the cloth storage rack 500 also includes a plurality of guide rail assemblies 560, and the plurality of guide rail assemblies 560 are arranged at intervals on the circumference of the lower frame; the guide rail assembly 560 includes a guide rail 561 and a rail wheel 562, the guide rail 561 is extended along the preset direction, and the rail wheel 562 is rotatably arranged on the lower frame 542, the rail wheel 562 and the guide rail 561 are in rolling cooperation, and at least one of the two ends of the rail wheel 562 has a rim, and the rim abuts the side of the guide rail; wherein, the side edges of the lower frame at both ends of the lower cloth guide roller are respectively provided with two guide rail assemblies 560, and in the two guide rail assemblies 560 located on the same side of the lower frame, the area between the two guide rail assemblies 560 is the inner side, the rail wheel 562 and the side of the guide rail 561 close to the inner side are in rolling cooperation, and the end of the rail wheel 562 close to the lower frame has the rim.

[0097] In these embodiments, the cloth storage rack 500 further includes a plurality of guide rail assemblies 560, which are spaced apart on the circumferential side of the lower frame, and can ensure that the lower cloth guide roller assembly 540 maintains smooth and precise position control during movement, thereby improving the stability and reliability of the entire system.

[0098] Each guide rail assembly 560 includes a guide rail 561 and a wheel 562. The guide rail 561 extends along a predetermined direction (typically having at least a vertical component) to guide the movement of the wheel 562. The wheel 562 is rotatably mounted on the lower frame 542 and engages with the guide rail 561 in a rolling manner.

[0099] At least one of the two ends of the rail wheel 562 has a rim, which abuts the side of the guide rail 561 to prevent the rail wheel 562 from derailing, thereby limiting the transmission of the lower frame 542. The end of the rail wheel 562 closest to the lower frame has a rim to ensure that the rail wheel 562 always moves along the direction of the guide rail 561 during movement. For example, the preset direction is vertical, and the lower cloth guide roller 541 and the upper cloth guide roller 531 are arranged in parallel and horizontally. The positioning of the rail wheel 562 and the guide rail ensures that the lower cloth guide roller 541 remains horizontal, preventing horizontal movement.

[0100] For example, in other embodiments, the rail wheel 562 may also be configured as a double-sided rail wheel 562, that is, both ends of the rail wheel 562 have a wheel flange.

[0101] Two guide rail assemblies 560 are installed on either side of the lower frame, located at either end of the lower cloth guide roller 541. The area between the two guide rail assemblies 560 on the same side of the lower frame is the inner side. A rolling engagement between the rail wheel 562 and the inner side of the guide rail 561 ensures that the lower cloth guide roller assembly 540 maintains a stable and precise position during movement.

[0102] When the adjustment assembly drives the lower cloth guide roller assembly 540 in a predetermined direction, the rail wheel 562 rolls along the guide rail 561, providing a smooth and stable motion path. The wheel rim design ensures that the rail wheel 562 does not deviate from the guide rail 561, enhancing system safety. Through the coordinated action of multiple guide rail assemblies 560, the lower cloth guide roller assembly 540 can move precisely between the upper and lower frames, adjusting the spacing between the upper and lower cloth guide roller assemblies 540 to maintain constant tension on the cloth 300.

[0103] The wheel rim of the rail wheel 562 abuts against the side of the guide rail 561, forming a mechanical limiting structure, which effectively prevents the rail wheel 562 from derailing when running at high speed or high load, thereby improving the safety of the equipment.

[0104] For ease of understanding, the working principle of this application is provided as follows: Before the cloth storage rack 500 passes the cloth 300, the tension sensor controller can be adjusted by tying a weighed weight with the cloth 300 in the middle of the upper cloth guide roller 531 equipped with a tension sensor (that is, one end of the cloth 300 is passed around the upper cloth guide roller 531 and fixed, and the other end with the weight automatically droops) so that the actual tension value is equal to the displayed value.

[0105] After the cloth 300 is threaded through the cloth storage rack 500, the "cloth drawing" button of the middle traction machine 700 is pressed. At this time, the front traction motor distributed on the left side of the cloth storage rack 500 and the middle traction motor distributed on the right side of the cloth storage rack 500 establish tension association.

[0106] Before the equipment is operated, the limit portion 543 on the lower cloth guide roller assembly 540 contacts the ground, at which time the lower limit switch indicator light is on, and the tension of the cloth 300 on the cloth storage rack 500 is set according to process requirements.

[0107] When the "Run" button is pressed, unwinding begins. According to the set tension, the control program system automatically calculates the torque and direction that the servo motor of the adjustment component needs to output, that is, when the gravity of the lower cloth guide roller assembly 540 is greater than the resultant force of the cloth 300 pulling the lower cloth guide roller assembly 540, the torque output by the servo motor balances the excess gravity of the lower cloth guide roller assembly 540 through the chain transmission mechanism 510; when the gravity of the lower cloth guide roller assembly 540 is less than the resultant force of the cloth 300 pulling the lower cloth guide roller assembly 540, the torque output by the servo motor balances the excess resultant force of the cloth 300 pulling the lower cloth guide roller assembly 540 through the chain transmission mechanism 510; no matter whether the gravity of the lower cloth guide roller assembly 540 is greater than or less than the resultant force of the cloth 300 pulling the lower cloth guide roller assembly 540, the torque output by the servo motor can keep the lower cloth guide roller assembly 540 in a balanced state through the chain transmission mechanism 510. When the weight of the lower cloth guide roller assembly 540 equals the combined force of the fabric 300 pulling on it, the servo motor stops operating. When the servo motor is actively rotating, it drives the lower cloth guide roller assembly 540 up and down via the chain drive mechanism 510. When the servo motor is passively rotating, the up and down movement of the lower cloth guide roller assembly 540 drives the chain drive mechanism 510 in the opposite direction. After the lower cloth guide roller assembly 540 reaches the set equilibrium position (low position), it stabilizes, and the cloth storage rack 500 is now fully stocked with fabric 300. The servo drive boasts high precision and fast response, allowing it to finely control the up and down movement of the lower cloth guide roller assembly 540 within a very narrow range during tension fluctuations.

[0108] After the unwinding machine 100 completes unwinding, it and the front traction machine 200 stop, and the remaining equipment continues to operate at the original speed. At this time, the lower guide roller assembly 540 of the cloth storage rack 500 begins to rise, and the cloth 300 on the cloth storage rack 500 begins to decrease. After the unwinding machine 100 completes the shaft change and joint work, the front traction motor and the middle traction motor start to establish tension, and unwinding begins. At this time, the cloth storage rack 500 begins to fall until it reaches the set equilibrium position (low position) again, and then operates stably.
