Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a fabric tension adaptive adjustment frame. Background Technology

[0002] In the fields of textiles, dyeing and printing, composite material processing, and specialty film manufacturing, tension control of fabrics (or flexible materials) is one of the core technical aspects of the production process. The stability of tension directly affects the physical properties of the product (such as breaking strength and elongation), appearance quality (such as wrinkles, creases, and thickness uniformity), and production efficiency. For example, in the textile industry, excessive fabric tension can lead to fiber breakage or equipment overload; insufficient tension can easily cause fabric slackness, folding, and even quality problems in subsequent processing (such as dyeing and coating). Therefore, achieving precise and stable adjustment of fabric tension is a critical requirement for relevant production lines.

[0003] Currently, existing fabric tension adjustment devices generally suffer from the following drawbacks:

[0004] Adjustment lag: Relying on manual experience or single speed adjustment, it cannot perceive and respond to tension changes in real time;

[0005] Poor adaptability: It is difficult to be compatible with fabrics of different thicknesses and materials, which can easily lead to pressure marks or slippage;

[0006] Limited detection accuracy: The lack of a dual "mechanical-electronic" feedback mechanism for tension changes results in insufficient adjustment accuracy.

[0007] Therefore, there is an urgent need for a new type of fabric tension regulating device that can detect tension in real time, adaptively adjust feeding / discharging resistance, be compatible with multiple fabric specifications, and have closed-loop control capabilities, in order to solve the above-mentioned technical problems. Utility Model Content

[0008] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a fabric tension adaptive adjustment frame that is easy to operate, highly compatible, and resistant to interference.

[0009] The technical solution adopted by this utility model to achieve the above-mentioned objective is as follows: a fabric tension adaptive adjustment frame, including a mounting frame, a feeding component, a tension detection component, and a discharging component. The upper end of the mounting frame is sequentially fixedly connected to the feeding component, the tension detection component, and the discharging component. The feeding component includes a first support frame, a first feeding roller, a second feeding roller, and a friction component. One end of the mounting frame is fixedly connected to two sets of symmetrical first support frames. The first feeding roller and the second feeding roller are rotatably connected between the first support frames. The rotating shaft of the second feeding roller is connected to the friction component. The friction component is fixedly connected to the first support frame. In use, the fabric passes between the first feeding roller and the second feeding roller. The friction component on one side of the second feeding roller increases or decreases its rotational resistance, thereby adjusting the tension of the fabric entering the device.

[0010] The tension detection assembly includes a second support frame, auxiliary rollers, a pressure measuring roller, and a pressure measuring device. Two sets of second support frames are fixedly connected to the upper middle part of the mounting frame. Two sets of auxiliary rollers are rotatably connected to the upper ends of the second support frames. A pressure measuring roller is rotatably connected between the second support frames below the auxiliary rollers. A pressure measuring device is connected to both ends of the pressure measuring roller. The pressure measuring devices are fixedly connected to the outside of the second support frames. The two sets of auxiliary rollers and the pressure measuring roller form a triangular structure. The fabric tension will cause the pressure measuring roller to move up and down, thereby detecting the tension of the fabric through the pressure measuring device. The friction force of the friction assembly is adjusted based on the detection result.

[0011] In the above technical solution, the discharge assembly includes a third support frame, a first discharge roller, a second discharge roller, and a discharge motor. Two sets of third support frames are fixedly connected to the other end of the mounting frame. The first discharge roller and the second discharge roller are rotatably connected between the third support frames. The rotating shaft of the second discharge roller passes through the third support frame and is connected to the discharge motor. The discharge motor is fixedly connected to the third support frame. The two ends of the first feed roller and the first discharge roller are rotatably connected to the pressure roller device.

[0012] In the above technical solution, the pressure roller device includes a sliding guide block, a pressure roller spring, a sliding plate, a threaded rod, and a handle. The first support frame and the second support frame are both provided with sliding groove holes. A sliding guide block is slidably connected within the sliding groove hole. The rotating shafts of the first feed roller and the first discharge roller are rotatably connected to the sliding guide block. A pressure roller spring is fixedly connected to the upper end of the sliding guide block. A sliding sleeve hole is connected to the upper end of the sliding groove hole. The upper end of the pressure roller spring is slidably connected within the sliding sleeve hole. A sliding plate is slidably connected within the sliding sleeve hole. The lower end of the sliding plate abuts against the top of the pressure roller spring. A threaded rod is rotatably connected to the upper end of the sliding plate. A threaded hole is provided at the upper end of the sliding sleeve hole, penetrating through the first support frame or the third support frame. The threaded rod is threadedly connected within the threaded hole. The upper end of the threaded rod passes through the threaded hole and is fixedly connected to the handle.

[0013] In the above technical solution, the friction assembly includes a friction wheel, friction plates, a linear guide rail, a mounting plate, and reinforcing ribs. The rotating shaft of the second feed roller passes through the first support frame and is connected to the friction wheel. Friction plates are respectively contacted and connected to both sides of the friction wheel. The outer sides of the friction plates are respectively connected to drive blocks. The drive blocks are respectively slidably connected to the linear guide rail. The linear guide rail is fixedly connected to the upper end of the mounting plate. One side of the mounting plate is fixedly connected to the first support frame. Several reinforcing ribs are fixedly connected between the first support frame and the mounting plate.

[0014] In the above technical solution, the pressure measuring device includes a sliding block, a connecting frame, a damping telescopic rod, a tension spring, a pressure sensor, and a fixed block. The second support frame has guide slots, and sliding blocks are slidably connected within each guide slot. The rotating shafts at both ends of the pressure measuring roller are rotatably connected to the sliding blocks. A connecting frame is fixedly connected to the sliding blocks, and a damping telescopic rod is fixedly connected to the connecting frame. The other end of the damping telescopic rod is fixedly connected to the fixed block. One side of the fixed block is fixedly connected to the second support frame. A tension spring is sleeved on the damping telescopic rod, and one end of the tension spring abuts against the pressure sensor. The pressure sensor is positioned between the damping telescopic rod and the fixed block.

[0015] The beneficial effects of this utility model are:

[0016] 1. Real-time adaptive adjustment solves the problem of traditional lag: The tension detection component collects the fabric tension signal (electrical signal output by the pressure sensor) in real time and synchronously feeds it back to the friction component and pressure roller device to realize a "detection-adjustment" closed loop. Compared with the existing fixed pressure roller or manual adjustment scheme, it can quickly respond to tension fluctuations (such as sudden changes in feed speed or differences in fabric material), avoiding wrinkles or breakage caused by adjustment lag.

[0017] 2. Strong compatibility with multiple fabric specifications, reducing changeover costs: The pressure roller device, through the elastic adjustment design of the sliding guide block, pressure roller spring and handle, can dynamically adjust the clamping pressure of the first feed roller / first discharge roller according to the fabric thickness (reduce pressure to prevent indentation for thin fabrics, and increase pressure to prevent slippage for thick fabrics); the linear guide rail and drive motor of the friction component can precisely adjust the contact pressure between the friction plate and the friction wheel, adapting to the differences in friction coefficients of different materials (such as cotton, chemical fiber, and composite fabrics), eliminating the need for frequent hardware replacements and significantly reducing production line changeover time and costs.

[0018] 3. High detection accuracy and strong anti-interference ability: The pressure measuring device adopts a combination structure of "damping telescopic rod + tension spring + pressure sensor". The damping telescopic rod can suppress the shaking of the pressure measuring roller caused by sudden tension changes (such as the instantaneous pulling of the fabric), and avoid signal distortion of the pressure sensor due to impact. The elastic force of the tension spring is strictly linearly related to the displacement of the pressure measuring roller (Hooke's Law). Combined with the real-time detection of the pressure sensor, the tension measurement accuracy is significantly improved, providing a reliable feedback basis for adjustment.

The friction assembly 104 on one side of the second feeding roller 103 increases or decreases its rotational resistance, thereby adjusting the tension of the fabric entering the device.

[0028] The tension detection assembly 2 includes a second support frame 201, an auxiliary roller 202, a pressure measuring roller 203, and a pressure measuring device 204. Two sets of second support frames 201 are fixedly connected to the upper middle part of the mounting frame 4. Two sets of auxiliary rollers 202 are rotatably connected to the upper ends of the second support frames 201. The pressure measuring rollers 203 are rotatably connected between the second support frames 201 below the auxiliary rollers 202. The pressure measuring devices 204 are connected to both ends of the pressure measuring rollers 203. The pressure measuring devices 204 are fixedly connected to the outside of the second support frames 201. The two sets of auxiliary rollers 202 and the pressure measuring rollers 203 form a triangular structure. The fabric tension will cause the pressure measuring rollers 203 to move up and down, thereby detecting the tension of the fabric through the pressure measuring device 204. The friction force of the friction assembly 104 is adjusted based on the detection result.

[0029] In the above technical solution, the discharge assembly 3 includes a third support frame 301, a first discharge roller 302, a second discharge roller 303, and a discharge motor 304.

The upper end of the sliding sleeve hole is provided with a threaded hole that passes through the first support frame 101 or the third support frame 301. The threaded rod 3054 is threadedly connected in the threaded hole. After the upper end of the threaded rod 3054 passes through the threaded hole, it is fixedly connected to the handle 3055. This is used to ensure that the feeding assembly 1 and the discharging assembly 3 exert a certain pressure on the fabric, and to ensure stable transmission between the feeding roller or the discharging roller. When in use, the handle 3055 is rotated. The handle 3055 drives the sliding plate 3053 to compress the pressure roller spring 3052 through the threaded rod 3054. The pressure of the pressure roller (first feeding roller 102, first discharging roller 302) on the fabric is adjusted by elastic adjustment.

[0031] In the above technical solution, the friction assembly 104 includes a friction wheel 1041, friction plates 1042, a linear guide rail 1043, a mounting plate 1044, and reinforcing ribs 1045. The rotating shaft of the second feed roller 103 passes through the first support frame 101 and is connected to the friction wheel 1041. Friction plates 1042 are respectively connected to both sides of the friction wheel 1041. The outer sides of the friction plates 1042 are respectively connected to the drive blocks. The drive blocks are slidably connected to the linear guide rail 1043. The linear guide rail 1043 is fixedly connected to the upper end of the mounting plate 1044. One side of the mounting plate 1044 is fixedly connected to... On the first support frame 101, a number of reinforcing ribs 1045 are fixedly connected between the first support frame 101 and the mounting plate 1044. The linear guide rail 1043 includes a groove rail, a drive motor and a bidirectional lead screw. In use, the drive motor drives the bidirectional lead screw to rotate, and the bidirectional lead screw drives the drive blocks to move towards or away from each other, thereby driving the friction plate 1042 to move closer to or away from the friction wheel 1041, and adjusting the friction force of the friction wheel 1041 in sequence. In this utility model, a spring and a pressure sensor 2045 can be added between the friction plate 1042 and the drive block to further improve the fine control of the friction force.

A tension spring 2044 is sleeved on the damping telescopic rod 2043. One end of the tension spring 2044 abuts against the pressure sensor 2045. The pressure sensor 2045 is located between the damping telescopic rod 2043 and the fixed block 2046. During use, the tension generated by the fabric will drive the pressure measuring roller 203 to move upward. The two ends of the pressure measuring roller 203 will drive the sliding block 2041 and the connecting frame 2042 to move upward. The distance between the connecting frame 2042 and the fixed block 2046 will shorten, thereby compressing the tension spring 2044. The spring compression is converted into spring force and applied to the pressure sensor 2045. The fabric tension is obtained by the pressure increased by the pressure sensor 2045.
