Description

Technical Field

[0001] This application belongs to the field of fabric production technology, and more specifically, relates to a fabric storage device. Background Technology

[0002] As the core raw material of the textile industry, fabric's subsequent processing is a key link in realizing product function and value. Common fabric processing flows mainly include multiple processes such as cutting, printing, sewing, coating, hot stamping, and embroidery; these processes have extremely high requirements for the continuity and stability of fabric supply, and a stable supply of fabric is the foundation for ensuring processing accuracy and product quality.

[0003] Currently, in the fabric processing stage, the traditional method of unwinding and traction conveying is commonly used in the feeding stage. The specific operation process is as follows: the rolled fabric is placed on support equipment such as unwinding frame, feeding roller or hydraulic lifting platform by manual or mechanical assistance. Then, the free end of the fabric roll is led out by manual traction or with the help of auxiliary mechanisms such as guide rollers and clamping rollers. After passing through pre-treatment components such as tension detection rollers and correction devices, it is directly fed into the feeding end of the processing equipment.

[0004] The inventors discovered that the fabric conveying speed is directly determined by the traction speed of the processing equipment. Due to insufficient speed matching accuracy between different processes, the fabric traction speed is prone to fluctuations in actual production. These speed fluctuations directly lead to drastic changes in the fabric tension: when the processing equipment traction speed suddenly increases or the fabric unwinding resistance is too high, the fabric tension rises instantaneously, easily causing excessive stretching or even tearing of the fabric fibers; when the processing equipment traction speed decreases or the fabric unwinding speed is too fast, the fabric tension decreases sharply, and the loose fabric is prone to accumulating, wrinkling, or layering in the conveying path. Therefore, there is an urgent need for a material storage device that can buffer fabric conveying speed fluctuations and stabilize tension to solve the above-mentioned problems in the prior art. Utility Model Content

[0005] The purpose of this application is to provide a fabric storage device to solve the technical problem that the tension cannot be guaranteed due to fluctuations in the fabric conveying speed during fabric processing.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A fabric storage device is provided, comprising: Frame, used for installation on a horizontal surface; The upper guide assembly is slidably connected to the frame in the vertical direction; A lower guide assembly is slidably connected to the frame in the vertical direction, and is located below the upper guide assembly; and An adjustment mechanism is provided on the frame and is connected to the upper guide assembly and the lower guide assembly in a transmission manner, so as to drive the upper guide assembly and the lower guide assembly to move towards each other or away from each other; The upper guide assembly and the lower guide assembly are used to alternately contact the two sides of the fabric so that the fabric extends meanderingly in the horizontal direction; Specifically, when the adjustment mechanism drives the upper guide assembly and the lower guide assembly to move towards or away from each other, the length of the meandering extension of the fabric is reduced or increased.

[0007] In one possible implementation, the upper feeding assembly includes: The upper movable seat is slidably connected to the frame in the vertical direction; and Multiple upper rollers, each designed to contact the underside of the fabric, are spaced horizontally on the upper movable seat, and each upper roller is rotatably connected to the upper movable seat.

[0008] In one possible implementation, the lower feeding assembly includes: The lower movable seat is slidably connected to the frame in the vertical direction; and Multiple lower rollers, each designed to contact the upper side of the fabric, are spaced horizontally on the lower movable seat, and each lower roller is rotatably connected to the lower movable seat.

[0009] In one possible implementation, the lower movable seat has a plurality of buffer springs arranged in parallel on its lower side.

[0010] In one possible implementation, the adjustment mechanism includes: Two first rotating shafts are arranged side by side on the upper side of the frame, and both first rotating shafts are rotatably connected to the frame; a synchronous drive component is provided between the two first rotating shafts to synchronize the rotation of the two first rotating shafts; one of the first rotating shafts is drivenly connected to a drive motor. Two sets of sprockets, each corresponding to one of the two first rotating shafts, each set of sprockets including two sprockets coaxially disposed at both ends of the corresponding first rotating shaft, and each sprocket being fixedly connected to the first rotating shaft; and Two sets of traction chains correspond one-to-one with two sets of sprockets. Each set of traction chains includes two traction chains, and each traction chain is meshed with the corresponding sprocket. The two ends of each traction chain are fixedly connected to the upper guide assembly and the lower guide assembly, respectively.

[0011] In one possible implementation, the synchronization drive component includes: The second rotating shaft is located between the two first rotating shafts and is rotatably connected to the frame; the axial direction of the second rotating shaft is perpendicular to the axial direction of the first rotating shaft. Two first bevel gears are coaxially and fixedly connected to both ends of the second rotating shaft; and Two second bevel gears correspond one-to-one with two first bevel gears, and the two second bevel gears are coaxially fixedly connected to the two first rotating shafts respectively; Each of the first bevel gears is meshed with a corresponding second bevel gear.

[0012] In one possible implementation, conveyor rollers are rotatably connected to both sides of the frame, one of the conveyor rollers being used to convey the fabric to the upper guide assembly and the lower guide assembly, and the other conveyor roller being used to drive the fabric away from the upper guide assembly and the lower guide assembly.

[0013] In one possible implementation, the fabric storage device further includes: A tension sensor is mounted on the frame, with its sensing end connected to the fabric to measure the tension of the fabric.

[0014] In one possible implementation, there are two tension sensors, which are arranged on both sides of the frame; the two tension sensors correspond one-to-one with the two conveyor rollers, and the detection end of each tension sensor is in contact with the fabric on the corresponding conveyor roller.

[0015] In one possible implementation, the fabric storage device further includes: A controller is mounted on the frame and is capable of presetting tension values; the signal input terminal of the controller is electrically connected to the tension sensor, and the signal output terminal of the controller is electrically connected to the adjustment mechanism.

[0016] In this embodiment, during the fabric conveying process, the upper and lower guide components form a horizontally meandering path through alternating contact. Initially, the device presets a material storage amount based on production needs. When the material storage amount needs adjustment, the adjustment mechanism activates and drives the upper and lower guide components to slide up and down along the frame: if more material needs to be stored, the adjustment mechanism moves them in opposite directions (the upper guide component slides upward, and the lower guide component slides downward), increasing the vertical distance between them. This increases the path length of the fabric in the meandering section, allowing for more fabric to be stored. If less material needs to be stored, the adjustment mechanism moves them in opposite directions (the upper guide component slides downward, and the lower guide component slides upward), decreasing the vertical distance. This shortens the path length of the fabric in the meandering section, and excess fabric is smoothly conveyed to meet the needs of downstream processes. Through the dynamic control of the adjustment mechanism, precise and continuous adjustment of the fabric storage amount is achieved.

[0017] Compared with the prior art, the fabric storage device provided in this application embodiment can dynamically adjust the length of the winding extension of the fabric in real time by adjusting the upper and lower guiding components to move in opposite directions or back to back through the adjustment mechanism. This enables flexible adjustment of the storage amount and can quickly adapt to changes in material supply and demand between different production speeds or processes, thereby improving the coordination and response speed of the production process and avoiding the impact of fabric conveying speed fluctuations on the fabric tension. For example, the storage amount is increased when the upstream supply is fast and the downstream processing is slow, and decreased otherwise. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] Please refer to the following: Figures 1 to 6 The fabric storage device provided in this application will now be described. The fabric storage device includes a frame 1, an upper guide assembly 2, a lower guide assembly 3, and an adjustment mechanism 4.

[0025] The frame 1 is made of welded profiles and is used to install on a horizontal surface to ensure the stability of the device foundation.

[0026] The upper guide assembly 2 is slidably connected to the frame 1 in the vertical direction.

[0027] The lower guide assembly 3 is slidably connected to the frame 1 in the vertical direction, and it is located below the upper guide assembly 2.

[0028] The adjustment mechanism 4 is mounted on the frame 1 and is connected to the upper guide assembly 2 and the lower guide assembly 3 in a transmission manner, so as to drive the upper guide assembly 2 and the lower guide assembly 3 to move towards each other or away from each other.

[0029] The upper guide assembly 2 and the lower guide assembly 3 are used to alternately engage with both sides of the fabric 9 so that the fabric 9 extends meanderingly in the horizontal direction.

[0030] Among them, when the adjusting mechanism 4 drives the upper guide assembly 2 and the lower guide assembly 3 to move towards or away from each other, the length of the meandering extension of the fabric 9 is reduced or increased.

[0031] Through the alternating contact of the upper guide component 2 and the lower guide component 3, the fabric 9 forms a meandering storage path; the adjustment mechanism 4 drives the two components to rise and fall synchronously through a transmission connection, changing the vertical height difference of the path, and thus adjusting the total length of the meandering section (i.e., the amount of material stored). The core idea is to use the concept of "trading space for length" to achieve dynamic storage of the fabric 9 by folding the vertical path within a limited horizontal space.

[0032] In this embodiment, during the conveying process, the fabric 9 forms a horizontally meandering path through the alternating contact of the upper guide assembly 2 and the lower guide assembly 3. Initially, the device presets the material storage amount according to production needs. When the material storage amount needs to be adjusted, the adjustment mechanism 4 is activated and drives the upper guide assembly 2 and the lower guide assembly 3 to slide up and down along the frame 1: if more material needs to be stored, the adjustment mechanism 4 drives the two to move in opposite directions (the upper guide assembly 2 slides upward and the lower guide assembly 3 slides downward), increasing the vertical distance between them, and the path length of the fabric 9 in the meandering extension section increases accordingly, thereby storing more fabric 9; if less material needs to be stored, the adjustment mechanism 4 drives the two to move in opposite directions (the upper guide assembly 2 slides downward and the lower guide assembly 3 slides upward), decreasing the vertical distance, shortening the path length of the meandering extension section of the fabric 9, and the excess fabric 9 is smoothly delivered to meet the needs of downstream processes. Through the dynamic control of the adjustment mechanism 4, the precise and continuous adjustment of the fabric 9 storage amount is achieved.

[0033] Compared with the prior art, the fabric storage device provided in this application embodiment can dynamically adjust the length of the meandering extension of the fabric 9 in real time by adjusting the upper and lower guide components 3 to move in opposite directions or back to back through the adjustment mechanism 4. This enables flexible adjustment of the storage amount and can quickly adapt to changes in material supply and demand between different production speeds or processes, thereby improving the coordination and response speed of the production process. This avoids the impact of fluctuations in the conveying speed of the fabric 9 on the tension of the fabric 9. For example, if the upstream supply is fast and the downstream processing is slow, the storage amount is increased, and vice versa.

[0034] In some embodiments, the above-mentioned upper feeding component 2 may adopt the following... Figures 1 to 6 The structure shown is described in the following document. Figures 1 to 6 The upper guide assembly 2 includes an upper movable seat 21 and multiple upper rollers 22.

[0035] The upper movable seat 21 is slidably connected to the frame 1 in the vertical direction.

[0036] Multiple upper rollers 22 are used to contact the lower side of the fabric 9, and are arranged horizontally at intervals on the upper movable seat 21, and each upper roller 22 is rotatably connected to the upper movable seat 21.

[0037] The upper moving seat 21 slides along the vertical guide rail of the frame 1, driving multiple upper rollers 22 to rise and fall synchronously; when the fabric 9 passes the upper guide assembly 2 from below, the outer circumferential surface of the upper roller 22 contacts the lower side of the fabric 9, and the upper roller 22 rotates with the friction of the fabric 9 during the movement of the fabric 9.

[0038] The upper movable seat 21 provides the mounting base and enables the sliding function. Multiple spaced upper rollers 22 rotate and contact the lower side of the fabric 9, converting sliding friction into rolling friction, reducing the resistance and wear between the fabric 9 and the guide assembly. The horizontally spaced arrangement can distribute the force on the fabric 9 and avoid excessive local pressure that could cause wrinkles.

[0039] By adopting the above technical solution, rolling friction replaces sliding friction, reducing the risk of scratching the surface of the fabric 9; multiple upper rollers 22 are distributed to contact the fabric 9, avoiding the fabric 9 from shifting or wrinkling due to single-point force; the combination design of the upper moving seat 21 and rollers is lightweight, reducing the load on the adjustment mechanism 4.

[0040] In some embodiments, the lower guide assembly 3 described above can be as follows: Figures 1 to 6 The structure shown is described in the following document. Figures 1 to 6 The lower guide assembly 3 includes a lower moving seat 31 and multiple lower rollers 32.

[0041] The lower movable seat 31 is slidably connected to the frame 1 in the vertical direction.

[0042] Multiple lower rollers 32 are used to contact the upper side of the fabric 9, and are arranged horizontally at intervals on the lower moving seat 31, and each lower roller 32 is rotatably connected to the lower moving seat 31.

[0043] The lower moving seat 31 slides along the vertical guide rail of the frame 1, driving multiple lower rollers 32 to rise and fall synchronously; when the fabric 9 passes over the lower guide assembly 3 from above, the outer circumferential surface of the lower roller 32 contacts the upper side of the fabric 9 and rotates as the fabric 9 moves.

[0044] Similar to the upper guide assembly 2, the lower moving seat 31 achieves a sliding function. Multiple lower rollers 32 contact the upper side of the fabric 9 by rolling, forming a meandering path of "upper pressure and lower support" in conjunction with the upper guide assembly 2. The horizontal spacing is also used to distribute the force and ensure that the fabric 9 is flat.

[0045] By adopting the above technical solution, in synergy with the upper guide component 2, a stable meandering path is formed to ensure that the fabric 9 does not loosen or stack during the storage process; it is suitable for high-speed conveying: the rolling contact resistance is small, which can match the higher conveying speed of the fabric 9; the structure is symmetrical: it is symmetrical with the upper guide component 2, which facilitates processing and assembly and reduces production costs.

[0046] In some embodiments, the lower movable seat 31 may be adopted as follows: Figures 1 to 6 The structure shown is described in the following document. Figures 1 to 6 The lower movable seat 31 has a plurality of buffer springs 33 arranged in parallel on its lower side.

[0047] The spring absorbs impact energy by utilizing its elastic deformation: when external pressure is applied to the lower moving seat 31, the spring is compressed to store elastic potential energy, thus mitigating the instantaneous impact force; after the pressure is released, the spring returns to its original length, allowing the lower moving seat 31 to return to its initial position, thus avoiding damage to the fabric 9 or device components from rigid impact.

[0048] By adopting the above technical solution, the fabric 9 and components can be protected: buffering instantaneous impacts, preventing the fabric 9 from being stretched or torn due to sudden tension changes, and reducing rigid collisions between the lower guide assembly 3 and the ground.

[0049] In some embodiments, the adjustment mechanism 4 described above may employ, for example... Figures 1 to 6 The structure shown is described in the following document. Figures 1 to 6 The adjustment mechanism 4 includes two first rotating shafts 41, two sets of sprockets 42 and two sets of traction chains 43.

[0050] Two first rotating shafts 41 are arranged side by side on the upper side of the frame 1, and both first rotating shafts 41 are rotatably connected to the frame 1; a synchronous drive component 5 is provided between the two first rotating shafts 41 to synchronize the rotation of the two first rotating shafts 41; one of the first rotating shafts 41 is connected to a drive motor 44.

[0051] Two sets of sprockets 42 correspond one-to-one with two first rotating shafts 41. Each set of sprockets 42 includes two sprockets 42 coaxially arranged at both ends of the corresponding first rotating shaft 41, and each sprocket 42 is fixedly connected to the first rotating shaft 41.

[0052] Two sets of traction chains 43 correspond one-to-one with two sets of sprockets 42. Each set of traction chains 43 includes two traction chains 43, and each traction chain 43 is meshed with the corresponding sprocket 42. The two ends of each traction chain 43 are fixedly connected to the upper guide assembly 2 and the lower guide assembly 3, respectively.

[0053] The working steps of the adjustment mechanism 4 are as follows: 1. Start the drive motor 44 to drive one of the first rotating shafts 41 to rotate; 2. The synchronous drive component 5 transmits power to the other first rotating shaft 41, so that the two first rotating shafts 41 rotate synchronously; 3. The sprockets 42 at both ends of the first rotating shaft 41 rotate with the shaft, driving the meshing traction chain 43 to move; 4. The two ends of the traction chain 43 are respectively connected to the upper guide component 2 and the lower guide component 3. When the chain moves, it drives the two to slide up and down along the frame 1 (one side of the chain rises and the other side of the chain descends, realizing opposite or opposite movement).

[0054] The rotational motion is converted into linear motion through the transmission chain of the drive motor 44, the first rotating shaft 41, the sprocket 42 and the traction chain 43: the two first rotating shafts 41 rotate synchronously, driving the sprockets 42 on both sides to rotate in the same direction, so that the chain connecting the upper and lower guide components 3 produces displacement in opposite directions (such as when the upper guide component 2 rises, the lower guide component 3 falls, and vice versa), realizing the synchronous movement of the two in opposite directions.

[0055] The sprocket 42 and chain can be replaced by a synchronous pulley and synchronous belt to reduce noise and wear, making it suitable for cleanroom environments. The drive motor 44 can be replaced by a servo motor, which, together with an encoder, can achieve closed-loop position control and improve adjustment accuracy. Alternatively, the synchronous drive component 5 can be eliminated, and two independent motors can be used to drive the two first rotating shafts 41 respectively, which are coordinated and synchronized by the controller 8 to increase fault redundancy.

[0056] By adopting the above technical solution, the two first rotating shafts 41 and the synchronous drive component 5 can ensure that the traction chains 43 on both sides of the device move in a consistent manner, and avoid the upper / lower guide components 3 from tilting; the chain drive has the advantage of strong load-bearing capacity and is suitable for heavy load scenarios; the above components are assembled independently, which is convenient for maintenance and replacement (such as the chain can be replaced separately after wear).

[0057] In some embodiments, the aforementioned synchronous drive component 5 may employ, for example... Figures 1 to 6 The structure shown is described in the following document. Figures 1 to 6 The synchronous drive component 5 includes a second rotating shaft 51, two first bevel gears 52 and two second bevel gears 53.

[0058] The second rotating shaft 51 is located between the two first rotating shafts 41 and is rotatably connected to the frame 1; the axial direction of the second rotating shaft 51 is perpendicular to the axial direction of the first rotating shaft 41.

[0059] The two first bevel gears 52 are coaxially fixedly connected to both ends of the second rotating shaft 51.

[0060] The two second bevel gears 53 correspond one-to-one with the two first bevel gears 52, and the two second bevel gears 53 are respectively coaxially fixedly connected to the two first rotating shafts 41.

[0061] Each of the first bevel gears 52 is meshed with the corresponding second bevel gear 53.

[0062] When the drive motor 44 drives a first rotating shaft 41 to rotate, it can drive the second bevel gear 53 on the first rotating shaft 41 to rotate; the second bevel gear 53 meshes with the first bevel gear 52 at the end of the second rotating shaft 51, driving the second rotating shaft 51 to rotate; the first bevel gear 52 at the other end of the second rotating shaft 51 drives another second bevel gear 53 to rotate, thereby driving another first rotating shaft 41 to rotate synchronously.

[0063] Power transmission between vertical shafts is achieved by utilizing the meshing characteristics of bevel gears: two first rotating shafts 41 are set in parallel, and a second rotating shaft 51 is perpendicular to the first rotating shaft 41. The rotation of one first rotating shaft 41 is transmitted to the other first rotating shaft 41 by meshing the first bevel gears 52 at both ends with the second bevel gears 53 on the first rotating shaft 41, ensuring that the two rotate in opposite directions and have the same speed.

[0064] By adopting the above technical solution, the bevel gear transmission has the advantages of small meshing clearance and high transmission accuracy, avoiding the jamming of the adjustment mechanism 4 caused by the speed difference between the two first rotating shafts 41; the vertical shaft layout saves space and makes the overall size of the adjustment mechanism 4 smaller; the bevel gear tooth surface has a large contact area, which can transmit a large torque and adapt to the heavy load requirements of the upper guide assembly 2 and the lower guide assembly 3.

[0065] In some embodiments, the frame 1 described above may be as follows: Figures 1 to 6 The structure shown is described in the following document. Figures 1 to 6 Both sides of the frame 1 are rotatably connected to conveyor rollers 6. One conveyor roller 6 is used to convey the fabric 9 to connect with the upper guide assembly 2 and the lower guide assembly 3, and the other conveyor roller 6 is used to drive the fabric 9 away from the upper guide assembly 2 and the lower guide assembly 3.

[0066] One side conveyor roller 6 rotates to transport the outer fabric 9 to contact the upper and lower guide components 3, forming a meandering path; the other side conveyor roller 6 rotates to pull the stored fabric 9 out of the meandering path and transport it to the downstream equipment.

[0067] The conveying roller 6 provides conveying power through friction with the fabric 9: the feed roller introduces the fabric 9 into the guiding assembly, and the discharge roller leads the fabric 9 out. The two work together to form a continuous flow of the fabric 9. The rotation speed of the conveying roller 6 can be adjusted according to the downstream processing speed, and works in conjunction with the adjustment mechanism 4 to control the amount of material stored.

[0068] By adopting the above technical solutions, a complete process of feeding, storing and discharging materials can be formed, ensuring an uninterrupted supply of fabric 9; and automated conveying reduces manual assistance and improves production efficiency.

[0069] In some embodiments, the above-mentioned fabric storage device may employ, for example, Figures 1 to 6 The structure shown is described in the following document. Figures 1 to 6 The fabric storage device also includes a tension sensor 7.

[0070] Tension sensor 7 is mounted on frame 1, and its detection end is connected to fabric 9 to measure the tension of fabric 9.

[0071] When the fabric 9 passes through, the detection end (such as the contact wheel) of the tension sensor 7 contacts the surface of the fabric 9; when the tension of the fabric 9 changes, the pressure or tension on the detection end changes, and the sensor converts the mechanical signal into an electrical signal output.

[0072] By adopting the above technical solution, abnormal tension of fabric 9 can be detected in a timely manner (such as excessive tension causing stretching, or insufficient tension causing stacking), providing a control basis for adjustment mechanism 4; deformation and wrinkles of fabric 9 caused by tension fluctuations can be avoided, ensuring downstream processing accuracy; and an alarm can be triggered when tension is abnormal to prevent equipment overload or damage to fabric 9.

[0073] In some embodiments, the tension sensor 7 described above may be as follows: Figures 1 to 6 The structure shown is described in the following document. Figures 1 to 6 There are two tension sensors 7, which are set on both sides of the frame 1. The two tension sensors 7 correspond one-to-one with the two conveyor rollers 6, and the detection end of each tension sensor 7 is connected to the fabric 9 on the corresponding conveyor roller 6.

[0074] Tension sensor 7 at the feed side conveyor roller 6 detects the tension of fabric 9 before it enters the device; tension sensor 7 at the discharge side conveyor roller 6 detects the tension of fabric 9 after it leaves the device; the signals from both sensors are transmitted to the operator simultaneously, and the difference between the feed and discharge tensions is analyzed by comparison.

[0075] The inlet and outlet tensions are compared by two-point tension detection: the feed tension reflects the upstream supply status, and the outlet tension reflects the downstream processing demand. The difference between the two can determine the tension loss or accumulation of the fabric 9 during the storage process, providing more accurate control parameters for the adjustment mechanism 4. When the outlet tension is greater than the feed tension, the control adjustment mechanism 4 increases the storage amount to buffer the tension.

[0076] By adopting the above technical solution, the limitations of single-point detection can be avoided, covering the entire process of fabric 9 entering, storing, and leaving; the distance between the upper guide component 2 and the lower guide component 3 can be dynamically adjusted based on the tension difference between the inlet and outlet to achieve closed-loop tension control; when the speed of the upstream and downstream equipment fluctuates, the dual-point detection can quickly respond and maintain the tension stability of fabric 9.

[0077] In some embodiments, the above-mentioned fabric storage device may employ, for example, Figures 1 to 6 The structure shown is described in the following document. Figures 1 to 6 The fabric storage device also includes a controller 8.

[0078] The controller 8 is mounted on the frame 1 and can preset the tension value; the signal input terminal of the controller 8 is electrically connected to the tension sensor 7, and the signal output terminal of the controller 8 is electrically connected to the adjustment mechanism 4.

[0079] The target tension value of fabric 9 is preset in controller 8 (this value is set according to parameters such as the material and thickness of fabric 9); tension sensor 7 detects the tension of fabric 9 in real time and transmits the signal to controller 8; controller 8 compares the actual tension with the preset value: If the actual tension is less than the preset value: control adjustment mechanism 4 drives the upper guide component 2 and the lower guide component 3 to move in opposite directions, increase the amount of material stored, and extend the path of the fabric 9 to increase the tension.

[0080] If the actual tension is greater than the preset value: control adjustment mechanism 4 drives the upper guide component 2 and the lower guide component 3 to move towards each other, reduce the amount of material stored, and shorten the path of the fabric 9 to reduce tension.

[0081] After adjustment, controller 8 maintains the current state until the tension deviates from the preset value again.

[0082] By adopting the above technical solution, real-time and precise control of the tension of fabric 9 can be achieved without manual intervention, reducing labor costs; by preset different tension parameters, the production of fabric 9 of different materials and specifications can be quickly switched, enhancing the versatility of the equipment.

[0083] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
