Description

Technical Field

[0001] This utility model relates to the field of yarn processing technology, specifically to an auxiliary device for stabilizing yarn tension. Background Technology

[0002] Yarn is a textile product made from various textile fibers processed into a certain fineness. It is used for weaving, rope making, thread making, knitting, and embroidery. Yarn is divided into short fiber yarn and continuous filament yarn. The fineness of yarn can be expressed in various ways, such as count, metric count, English count, denier, etc. The twist of yarn is expressed as the number of twists per meter or inch. Wool yarn is generally used to weave sweaters, wool pants, wool vests, scarves, hats and gloves, and to weave various spring and autumn clothing and accessories. In addition to warmth, it also has a decorative function. A yarn tension stabilization auxiliary device is an electromechanical device installed in the spinning, winding, weaving or knitting process. Its core function is to automatically monitor and adjust the tension of the yarn during operation to keep it within a preset and stable range.

[0003] In some existing yarn tension stabilization auxiliary devices, during yarn processing, the mounting frame is first installed on the upper end of the equipment by bolts and nuts. By winding the yarn around the upper end of the tension wheel, the position of the tension wheel is adjusted by bolts, knobs, springs and counterweights. Tightening the bolts pushes the tension wheel up and down, or the counterweights are added or removed to change the tension.

[0004] Existing yarn tension stabilization auxiliary devices have the following problems: installing the tension stabilization auxiliary device with bolts and nuts during yarn processing wastes a lot of time and manpower, affecting the yarn processing progress. At the same time, relying on manual adjustment of tension results in poor accuracy. Therefore, we propose a yarn tension stabilization auxiliary device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a yarn tension stabilization auxiliary device. During the yarn processing, the extrusion of the extrusion block and the quick installation of external equipment avoid the waste of a lot of time and manpower, improve the yarn processing progress, and automatically adjust the yarn tension. The tension adjustment accuracy is more precise, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a yarn tension stabilization auxiliary device, comprising a mounting frame, a mounting mechanism, and a tension adjustment mechanism;

[0007] The mounting mechanism includes a rotating shaft, extrusion blocks, worm gears, and worms. A protective cover is provided at the front end of the mounting frame. The front wall of the mounting frame is rotatably connected to the uniformly distributed extrusion blocks via the rotating shaft. Worm gears are fixedly sleeved on the front side of the outer surface of the rotating shaft. Worms are rotatably connected between the left and right inner walls of the protective cover. The worm gears are all meshed with the worms.

[0008] Tension adjustment mechanism: It includes support rods and support bars. The upper end of the mounting frame is provided with an adjustment platform. The middle of the upper end of the adjustment platform is provided with symmetrical support rods. Support bars are slidably connected between the two support rods. The upper end of the support bars is provided with symmetrical columns. A tension wheel is provided between the upper ends of the two columns. During yarn processing, the extrusion of the extrusion block and the quick installation of external equipment avoid a lot of wasted time and manpower, improve the processing progress of yarn, and automatically adjust the tension of the yarn, with more accurate tension adjustment.

[0009] Furthermore, a microcontroller is provided on the outside of the mounting bracket. The input terminal of the microcontroller is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0010] Furthermore, the installation mechanism also includes an adjusting rod, a turntable, a locking bolt, and a vertical plate. The adjusting rod is fixedly sleeved on the outer surface of the right end of the worm gear, and the turntable is fixedly connected to the right end of the worm gear. A vertical plate is provided on the right side of the front end of the mounting frame. The internal thread of the threaded hole at the right end of the vertical plate is connected to a locking bolt. The left end of the locking bolt is inserted into the insertion hole at the edge of the turntable for easy adjustment.

[0011] Furthermore, the tension adjustment mechanism also includes a guide rod, a sliding rod, a U-shaped block one, a connecting rod, and a U-shaped block two. A symmetrical guide rod is fixedly connected between the left and right inner walls of the adjustment platform. A symmetrical sliding rod is slidably connected between the two guide rods. A symmetrical U-shaped block one is provided at the upper end of each sliding rod. A symmetrical U-shaped block two is provided at the left and right ends of each support bar. A connecting rod is rotatably connected between the U-shaped block one and the adjacent U-shaped block two via a pin, providing a rotatable connection.

[0012] Furthermore, the tension adjustment mechanism also includes a drive assembly, which includes a bidirectional screw and an angle sensor. The bidirectional screw is rotatably connected to the middle of the left and right inner walls of the adjustment platform. The threaded hole in the middle of the sliding rod is threadedly connected to the left and right ends of the bidirectional screw, respectively. An angle sensor is provided at the left end of the adjustment platform. The middle of the counting shaft of the angle sensor is fixedly connected to the left end of the bidirectional screw. The angle sensor is bidirectionally electrically connected to the microcontroller to provide angle monitoring.

[0013] Furthermore, the drive assembly also includes a motor, which is located at the right end of the adjustment platform. The left end of the motor's output shaft is fixedly connected to the right end of the bidirectional screw, and the input end of the motor is electrically connected to the output end of the microcontroller to provide lifting drive.

[0014] Furthermore, the upper end of each column is hinged to a mounting plate, and the tension wheel is located inside a circular hole formed between the lower end of the mounting plate and the upper end of the vertically adjacent column, which facilitates fixing.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This yarn tension stabilization auxiliary device has the following advantages:

[0016] 1. The worm gear and worm wheel are rotated by the adjusting rod, which in turn drives the rotating shaft to rotate. The rotating shaft drives the extrusion blocks to rotate. The inclined surfaces of multiple extrusion blocks extrude against the front edge of the equipment frame, and the rear wall of the mounting frame extrudes against the rear edge of the equipment frame. After fixing, the turntable is locked by locking bolts and insertion holes, thereby realizing the rapid installation of the device and external equipment, avoiding the waste of a lot of time and manpower, and improving the processing progress of yarn spinning.

[0017] 2. Driven by the motor, the sliding rod slides along the guide rod through the bidirectional screw. The sliding rod drives the support bar to slide up and down along the support rod through the hinge of U-block one, connecting rod and U-block two. The up and down movement of the support bar affects the height of the tension wheel. When the tension wheel rises, the yarn tension increases, and when it falls, the tension decreases, thereby realizing automatic adjustment of the yarn tension, and the adjustment accuracy of the tension is more precise.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-5 This embodiment provides a technical solution: a yarn tension stabilization auxiliary device, including a mounting frame 1, a mounting mechanism 3, and a tension adjustment mechanism 5. A microcontroller 9 is provided on the outside of the mounting frame 1. The input end of the microcontroller 9 is electrically connected to an external power source. The upper ends of the columns 6 are respectively hinged to mounting plates 7. The tension wheel 8 is located inside the circular hole formed between the lower end of the mounting plate 7 and the upper end of the vertically adjacent column 6. (The left end of the mounting plate 7 is respectively fixed to the left side of the upper end of the vertically adjacent column 6 by bolts). Then, the bolts on the upper end of the mounting plate 7 are unscrewed. Then, the mounting plate 7 is flipped open and the tension wheel 8 is placed between the upper ends of the two columns 6. Then, the mounting plate 7 is flipped back and the bolts are screwed on to install the tension wheel 8. (The tension wheel 8 is rotatably connected to the circular hole formed between the lower end of the mounting plate 7 and the upper end of the vertically adjacent column 6 through the rotating shaft at the end). The yarn is passed around the upper end of the arc surface of the tension wheel 8.

[0026] Mounting mechanism 3 includes a rotating shaft 31, extrusion blocks 32, worm gears 33, and worm 34. A protective cover 2 is provided at the front end of the mounting frame 1. The front wall of the mounting frame 1 is rotatably connected to evenly distributed extrusion blocks 32 via the rotating shaft 31. Worm gears 33 are fixedly sleeved on the front side of the outer surface of the rotating shaft 31. Worm 34 is rotatably connected between the left and right inner walls of the protective cover 2. The worm gears 33 are all meshed with the worm 34. Mounting mechanism 3 also includes an adjusting rod 35, a turntable 36, a locking bolt 37, and a vertical plate 38. An adjusting rod 35 is fixedly sleeved on the outer surface of the right end of the worm 34. The right end of the worm 34 is fixedly connected to the turntable 36. A vertical plate 38 is provided on the right side of the front end of the mounting frame 1. A locking bolt 37 is threaded into the threaded hole at the right end of the vertical plate 38. The left end of the locking bolt 37 is connected to the edge of the turntable 36. When adjusting the tension of the spinning yarn, the operator first rotates the adjusting rod 35, which drives the worm 34 to rotate synchronously. Since the worm 34 meshes with all the worm wheels 33, the rotation of the worm 34 will drive multiple worm wheels 33 and the rotating shaft 31 fixed to it to rotate synchronously. When the rotating shaft 31 rotates, it drives the squeezing block 32 on the front wall of the mounting frame 1 to rotate. Multiple squeezing blocks 32 work together to clamp the mounting position of the spinning equipment (such as the roller bracket and the yarn guide frame) from different directions, realizing the quick docking of the device and the equipment. After the fixing is completed, the locking bolt 37 on the upright plate 38 is turned so that its left end is inserted into the insertion hole on the edge of the turntable 36, which restricts the rotation of the turntable 36, thereby locking the position of the worm 34 and the worm wheel 33, preventing the squeezing block 32 from loosening due to equipment vibration, and ensuring that the installation is stable.

[0027] Tension adjustment mechanism 5: It includes support rods 55 and support bars 56. The upper end of the mounting frame 1 is provided with an adjustment platform 4. The middle of the upper end of the adjustment platform 4 is provided with symmetrical support rods 55. The support bars 56 are slidably connected between the two support rods 55. The upper end of the support bars 56 is provided with symmetrical columns 6. The upper ends of the two columns 6 are provided with tension wheels 8. The tension adjustment mechanism 5 also includes guide rods 51, sliding rods 52, U-shaped blocks 53, connecting rods 54 and U-shaped blocks 57. The left and right inner walls of the adjustment platform 4 are fixedly connected with symmetrical guide rods 51. The left and right sliding rods 52 are slidably connected between the two guide rods 51. The upper ends of the sliding rods 52 are respectively provided with symmetrical U-shaped blocks 53. The left and right ends of the support bars 56 are respectively provided with front and rear symmetrical U-shaped blocks 53. The rear-symmetrical U-shaped second 57, U-shaped block 53 and the laterally adjacent U-shaped second 57 are respectively connected by connecting rods 54 via pins. The tension adjustment mechanism 5 also includes a drive assembly 58, which includes a bidirectional screw 582 and an angle sensor 583. The bidirectional screw 582 is rotatably connected to the middle of the left and right inner walls of the adjustment platform 4. The threaded hole in the middle of the sliding rod 52 is threaded to the left and right ends of the bidirectional screw 582 respectively. (A bellows can be fixedly connected between the left wall of the adjustment platform 4 and the left end of the left sliding rod 52, between the inner sides of the two sliding rods 52, and between the right end of the right sliding rod 52 and the right wall of the adjustment platform 4 respectively. The bellows will be sleeved on the outside of the bidirectional screw 582. The bellows will control the movement of the bidirectional screw 582.) To ensure the sealing and lubrication of the bidirectional screw 582, the left end of the adjusting table 4 is equipped with an angle sensor 583. The middle of the counting shaft of the angle sensor 583 is fixedly connected to the left end of the bidirectional screw 582. The angle sensor 583 is bidirectionally electrically connected to the microcontroller 9. The drive assembly 58 also includes a motor 581, which is located at the right end of the adjusting table 4. The left end of the output shaft of the motor 581 is fixedly connected to the right end of the bidirectional screw 582. The input end of the motor 581 is electrically connected to the output end of the microcontroller 9. Then, by controlling the microcontroller 9, the output shaft of the motor 581 drives the bidirectional screw 582 to rotate. Since the threaded hole in the middle of the sliding rod 52 is threadedly connected to the left and right ends of the bidirectional screw 582, the thread directions at both ends of the bidirectional screw 582 are opposite. When the bidirectional screw 582 rotates, it drives the two sliding rods 52 to slide laterally in opposite directions along the guide rod 51. When the sliding rods 52 move laterally, through the hinge structure of U-shaped block 1 53, connecting rod 54 and U-shaped block 2 57, the support bar 56 is driven to slide up and down along the support rod 55. When the sliding rods 52 move in opposite directions, the connecting rod 54 pushes the support bar 56 up; when the sliding rods 52 move in opposite directions, the support bar 56 descends. The up and down movement of the support bar 56 directly changes the height of the tension wheel 8 at the upper end of the column 6, thereby adjusting the tension of the yarn when it passes over the tension wheel 8. When the tension wheel 8 rises, the yarn tension increases; when it falls, the tension decreases. The angle sensor 583 detects the rotation angle of the bidirectional screw 582 in real time and transmits the data to the microcontroller 9.The microcontroller 9 calculates the moving distance of the sliding rod 52 and the lifting height of the support bar 56 based on the angle data, thereby accurately controlling the position of the tension wheel 8. When the pitch of the bidirectional screw 582 is one centimeter, a 360-degree rotation of the bidirectional screw 582 corresponds to a axial movement of one centimeter in the sliding rod 52. This movement, through the U-shaped block 53, connecting rod 54, and U-shaped section 57, causes the support bar 56 to lift the tension wheel 8 by one centimeter, thus achieving tension adjustment control and preventing over-adjustment or under-adjustment.

[0028] The working principle of the yarn tension stabilization auxiliary device provided by this utility model is as follows: When adjusting the tension of the yarn, the operator first rotates the adjusting rod 35, which drives the worm 34 to rotate synchronously. Since the worm 34 meshes with all the worm wheels 33, the rotation of the worm 34 will drive multiple worm wheels 33 and the rotating shaft 31 fixed thereto to rotate synchronously. When the rotating shaft 31 rotates, it drives the squeezing block 32 on the front wall of the mounting frame 1 to rotate. Multiple squeezing blocks 32 work together to clamp the mounting position of the spinning equipment, such as the roller bracket and the yarn guide frame, from different directions, so as to realize the quick docking of the device and the equipment. After the fixing is completed, the locking screw on the upright plate 38 is turned. Bolt 37 is inserted into the insertion hole on the edge of turntable 36 with its left end, restricting the rotation of turntable 36 and locking the position of worm gear 34 and worm wheel 33 to prevent equipment vibration from causing the extrusion block 32 to loosen and ensure stable installation. Then, the bolts on the upper end of mounting plate 7 are unscrewed. Next, mounting plate 7 is flipped open and tension wheel 8 is placed between the upper ends of the two columns 6. Then, mounting plate 7 is flipped back and the bolts are tightened to install tension wheel 8. The yarn is then passed around the upper end of the arc surface of tension wheel 8. Then, through the control of microcontroller 9, the output shaft of motor 581 drives bidirectional screw 582 to rotate. Because the threaded hole in the middle of sliding rod 52 is connected to the left and right sides of bidirectional screw 582... The double-ended screw 582 has threads at both ends with opposite thread directions. When the double-ended screw 582 rotates, it drives the two sliding rods 52 to slide laterally along the guide rod 51 in opposite directions. When the sliding rods 52 move laterally, through the hinge structure of U-block 1 53, connecting rod 54 and U-block 2 57, the support bar 56 slides up and down along the support rod 55. When the sliding rods 52 move in opposite directions, the connecting rod 54 pushes the support bar 56 up; when the sliding rods 52 move in opposite directions, the support bar 56 descends. The up and down movement of the support bar 56 directly changes the height of the tension wheel 8 at the upper end of the column 6, thereby adjusting the tension of the yarn when it passes over the tension wheel 8. When the tension wheel 8 rises, the yarn tension increases; when it falls, the tension decreases. The angle sensor 583 detects the rotation angle of the bidirectional screw 582 in real time and transmits the data to the microcontroller 9. The microcontroller 9 calculates the moving distance of the sliding rod 52 and the lifting height of the support bar 56 based on the angle data, thereby accurately controlling the position of the tension wheel 8. When the pitch of the bidirectional screw 582 is one centimeter, the bidirectional screw 582 rotates 360 degrees, and the sliding rod 52 moves axially by one centimeter. This, in turn, causes the support bar 56 to drive the tension wheel 8 to rise by one centimeter through the U-shaped block 53, connecting rod 54, and U-shaped block 57, thus achieving tension adjustment control and avoiding over-adjustment or under-adjustment.

[0029] It is worth noting that the motor 581 and angle sensor 583 disclosed in the above embodiments can be YJ61 and STM32F103 respectively. The microcontroller 9 controls the operation of the motor 581 and angle sensor 583 using methods commonly used in the prior art.
