Technical Field
[0001] This utility model relates to the field of tension adjustment technology, specifically a cotton yarn tension adjustment device. Background Technology
[0002] Existing tension regulating devices do not take into account the softness of cotton yarn and the gradual loosening of the device over time. Therefore, it is necessary to implement automatic tension detection and automatic tensioning to passively stretch the cotton yarn on the regulating device, thereby increasing the tension and preventing the yarn from becoming loose. Thus, a cotton yarn tension regulating device that solves the above problems is needed. Utility Model Content
[0003] In view of the shortcomings of the prior art, this utility model provides a cotton yarn tension adjustment device, which solves the problems mentioned in the background.
[0004] This utility model provides the following technical solution: a cotton yarn tension adjusting device, comprising: a device frame, a rotating roller movably sleeved on the inner wall of the device frame, a limiting piece sleeved on the outer wall of the rotating roller, an outer cylinder fixedly sleeved on the outer wall of the rotating roller, a sliding groove formed on the inner wall of the device frame, a rotary motor mounted on the outer wall of the device frame, a bidirectional lead screw connected to the outer wall of the rotary motor, a fixing block fixedly mounted on the outer wall of the device frame, a limiting block sleeved on the outer wall of the bidirectional lead screw, a tension shaft sleeved on the inner wall of the limiting block, a threaded hole formed on the inner wall of the tension shaft, a tension roller fixedly sleeved on the outer wall of the tension shaft, cotton yarn overlapping the outer wall of the tension roller, an adjusting cavity formed on the inner wall of the device frame, an adjusting hole formed on the outer wall of the device frame, a connector sleeved on the inner wall of the adjusting cavity, and an adjusting pin connected to the inner wall of the connector.
[0005] Preferably, the number of limiting pieces is four, and the four limiting pieces are symmetrically arranged in pairs on the outer wall of the rotating roller.
[0006] Preferably, the diameter of the outer cylinder is the same as the diameter of the tension roller, and the distance between the two outer cylinders is less than the distance between the two tension rollers.
[0007] Preferably, the inner wall of the sliding groove is adapted to the size of the outer wall of the tension shaft, and the tension shaft slides along the inner wall of the sliding groove.
[0008] Preferably, a bidirectional lead screw is connected to the power output shaft of the rotary motor, and the outer wall of the bidirectional lead screw is provided with bidirectional helical patterns.
[0009] Preferably, the number of adjustment holes is several, and the several adjustment holes are arranged on the outer wall of the device frame.
[0010] Preferably, the connector is configured in a "T" shape, and the outer wall of the connector is the same size as the inner wall of the adjustment cavity.
[0011] Preferably, a pressure sensor is installed on the outer wall of the connector, and the pressure sensor is located at the bottom of the cotton gauze.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This cotton yarn tension regulating device, by setting up a rotary motor, threaded hole, tension rollers, cotton yarn, etc., requires the cotton yarn on the device to pass through two tension rollers and be output outside the device. The rotary motor on the device controls the rotation of the bidirectional screw, and the bidirectional spiral of the bidirectional screw and the meshing of the threaded hole cause the two tension rollers to move closer to the middle or pull apart to the sides, thereby allowing the two tension rollers to control the tension of the cotton yarn.
[0014] 2. This cotton yarn tension adjustment device, through the setting of a pressure sensor, cotton yarn, and a rotary motor, allows the cotton yarn on the device to be tensioned and supported by two tension rollers. The pressure sensor, located in the middle of the two tension rollers and at the bottom of the cotton yarn, senses the tension. When the tension of the two tension rollers is relaxed, the cotton yarn will naturally form an arc-shaped downward state from the middle. The pressure sensor then detects the insufficient tension of the cotton yarn and triggers the rotary motor to output rotational power, automatically stretching the tension of the cotton yarn to both sides.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 A cotton yarn tension adjusting device includes: a frame 1, a rotating roller 2 movably sleeved on the inner wall of the frame 1, a limiting piece 3 sleeved on the outer wall of the rotating roller 2, an outer cylinder 4 fixedly sleeved on the outer wall of the rotating roller 2, a sliding groove 5 formed on the inner wall of the frame 1, a rotary motor 6 installed on the outer wall of the frame 1, a bidirectional lead screw 7 connected to the outer wall of the rotary motor 6, a fixing block 8 fixedly installed on the outer wall of the frame 1, a limiting block 9 sleeved on the outer wall of the bidirectional lead screw 7, a tension shaft 10 sleeved on the inner wall of the limiting block 9, a threaded hole 11 formed on the inner wall of the tension shaft 10, a tension roller 12 fixedly sleeved on the outer wall of the tension shaft 10, cotton yarn 13 overlapping the outer wall of the tension roller 12, an adjusting cavity 14 formed on the inner wall of the frame 1, an adjusting hole 15 formed on the outer wall of the frame 1, a connector 16 sleeved on the inner wall of the adjusting cavity 14, and an adjusting pin 17 connected to the inner wall of the connector 16.
[0023] The number of limiting plates 3 is four. The four limiting plates 3 are symmetrically arranged in pairs on the outer wall of the rotating roller 2. The two rotating rollers 2 on the device are sleeved in the inner wall of the device frame 1, so that the rotating roller 2 on the device is limited by the symmetrically arranged limiting plates 3 on the outer wall of the rotating roller 2 and the outer side of the device frame 1, thereby preventing the rotating roller 2 on the device from falling off the device during rotation.
[0024] The outer cylinder 4 has the same diameter as the tension roller 12, and the distance between the two outer cylinders 4 is less than the distance between the two tension rollers 12. By setting the two outer cylinders 4 at a position lower than the tension rollers 12, the cotton yarn 13 needs to bypass the outer cylinders 4 for input and transport when it needs to enter or exit the device. Thus, the cotton yarn 13 is subjected to tension by the distance between the two tension rollers 12 when it passes through the two tension rollers 12.
[0025] The inner wall of the sliding groove 5 is adapted to the size of the outer wall of the tension shaft 10, and the tension shaft 10 slides along the inner wall of the sliding groove 5. When the tension shaft 10 on the device moves under the influence of the bidirectional screw 7, the tension shaft 10 on the device can slide laterally along the inner wall of the sliding groove 5, so that the tension shaft 10 on the device has enough room to move.
[0026] The rotary motor 6 has a bidirectional lead screw 7 connected to its power output shaft. The outer wall of the bidirectional lead screw 7 is provided with bidirectional spiral threads. When the rotary motor 6 outputs rotational power, the bidirectional lead screw 7 is driven to rotate by the rotary motor 6. The bidirectional threads on the outer wall of the bidirectional lead screw 7 cause the tension shaft 10 on the device to mesh with the bidirectional lead screw 7 through the threaded hole 11, thereby causing the bidirectional lead screw 7 to drive the tension shaft 10 to move in opposite directions.
[0027] The number of adjustment holes 15 is several, and the several adjustment holes 15 are arranged on the outer wall of the device frame 1. The inner wall of the several adjustment holes 15 on the device is threaded with the outer wall of the adjustment pin 17, so that the connector 16 on the device can be connected to the adjustment pin 17 and the adjustment hole 15 by thread, thereby enabling the connector 16 on the device to flexibly switch its height.
[0028] The connector 16 is configured in a "T" shape, and the outer wall of the connector 16 is the same size as the inner wall of the adjustment cavity 14. The connector 16 extends out of the inner cavity of the adjustment cavity 14 and reaches the bottom of the cotton gauze 13. The outer connector 16 cooperates with the adjustment nail 17 for installation, so that the connector 16 on the device can be fixedly installed while bearing the pressure sensor 18.
[0029] The connector 16 has a pressure sensor 18 installed on its outer wall. The pressure sensor 18 is located at the bottom of the cotton yarn 13. The cotton yarn 13 is supported by two tension rollers 12 on the device, which apply tension to the cotton yarn 13. This allows the pressure sensor 18 on the device to detect the part of the cotton yarn 13 that falls naturally downward in an arc shape at the middle of the two tension rollers 12. This allows the pressure sensor 18 to be automatically triggered when the tension of the cotton yarn 13 is insufficient.
[0030] The working principle involves first setting up a rotary motor 6, a threaded hole 11, tension rollers 12, and cotton yarn 13. The cotton yarn 13 passes through two tension rollers 12 before being output outside the device. The rotary motor 6 controls the rotation of a bidirectional lead screw 7. The bidirectional spiral of the lead screw 7 engages with the threaded hole 11, causing the two tension rollers 12 to either move closer together or further apart. This allows the two tension rollers 12 to control the tension of the cotton yarn 13. Furthermore, a pressure sensor 18, cotton yarn 13, and rotary motor 6 are also included. The structure allows the cotton yarn 13 on the device to be tensioned and supported by the two tension rollers 12. When the pressure sensor 18 is located in the middle of the two tension rollers 12 and at the bottom of the cotton yarn 13, it will cause the tension of the two tension rollers 12 to relax. The cotton yarn 13 will naturally form an arc-shaped downward state from the middle part. Then, the pressure sensor 18 will detect the insufficient tension of the cotton yarn 13 and trigger the rotational power output of the rotary motor 6 to automatically stretch the tension of the cotton yarn 13 to both sides.
