Description

Technical Field

[0001] This utility model relates to the field of knitted glove production technology, specifically a yarn tension adjustment device for knitted glove production. Background Technology

[0002] In the utility model patent application CN220467154U, with an application publication date of February 9, 2024, entitled "A Textile Yarn Tension Adjustment Device", this utility model discloses a textile yarn tension adjustment device, comprising: a guide assembly, which includes a base plate and a guide member disposed on the base plate, the guide member being used to guide the transmission path of the yarn into a zigzag shape adjacent to the base plate to tension the yarn; a dust suction port disposed on the base plate facing the yarn transmission path; a collection box, in which a screen is detachably connected to divide the inner cavity of the collection box into an air inlet chamber and an air outlet chamber, the air outlet chamber being connected to an air extraction device; the base plate having two working positions, in the first working position, the dust suction port is connected to the air inlet chamber, and in the second working position, the base plate is separated from the collection box to allow the screen to be detachably connected to the collection box. This textile yarn tension regulating device draws air from the collection box using an air extraction device, creating a negative pressure inside the collection box. This attracts impurities from the yarn near the suction port, achieving cleaning of the yarn without contact with it, thus preventing yarn wear and improving cleaning quality.

[0003] In the production of knitted gloves, the tension stability of the yarn directly affects the knitting quality. If the yarn tension is too high, it is easy for the yarn to break, increasing production losses; if the tension is too low, the knitted gloves will have a loose texture and uneven density, affecting the product's appearance and lifespan.

[0004] Existing yarn tension regulating devices mostly employ simple spring or counterweight structures for tension control, resulting in low adjustment accuracy and difficulty in flexibly adjusting to different yarn materials and thicknesses. Furthermore, the fixed conductor structure of traditional devices makes the yarn prone to shifting and tangling during transmission, further affecting tension stability. In addition, the low transmission efficiency of the take-up and let-off mechanisms and poor speed matching between the take-up and let-off shuttles also lead to yarn tension fluctuations. Therefore, a yarn tension regulating device with high adjustment accuracy, stable conductor, and reliable transmission is needed to meet the high-quality production requirements of knitted gloves. Utility Model Content

[0005] The purpose of this invention is to provide a yarn tension adjustment device for knitted glove production, so as to solve the problems of low yarn tension adjustment accuracy, unstable conductors, and poor transmission efficiency in the prior art mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a yarn tension adjusting device for knitting glove production, comprising a base, a turntable mounted on the top of the base, a take-up shuttle engaged with the top of the turntable, a spring buckle mounted on the top of the turntable, a pay-off shuttle mounted on the top of the turntable, a bracket fixedly connected to the outer wall of the base, a tension adjusting assembly mounted on the top of the bracket, a wire assembly mounted on the top of the base, a winding motor mounted on the top of the base, and a belt roller fixedly connected to the output shaft of the winding motor via a coupling, with a belt disposed on the outer side of the belt roller.

[0007] Furthermore, the wire feeding shuttle is fixedly installed above another set of turntables by bolts, and the wire taking-up shuttle is connected to another set of belt rollers, and the belt rollers are connected to the other belt rollers via belt drive.

[0008] Furthermore, the tension adjustment assembly includes a drive motor, a drive gear, a rack, a reduction gear, and a twisted ball tension gyroscope. The drive motor is mounted on the outer wall of the bracket, and the output shaft of the drive motor is fixedly connected to the drive gear via a coupling. The reduction gear is mounted on the top of the bracket, and the outer wall of the reduction gear is meshed with a rack. The output end of the reduction gear is fixedly connected to the twisted ball tension gyroscope.

[0009] Furthermore, the drive gear is connected to the reduction gear by a rack, and the size of the reduction gear is larger than that of the drive gear.

[0010] Furthermore, the twisted baran tension gyroscope is provided with a tilted gyroscope and a rotating shaft structure, and the tilt angle of the gyroscope is 30°.

[0011] Furthermore, the conductor assembly includes a slide rail, a drive pulley, and a conductor bracket. The top of the bracket is fixedly connected to the slide rail, the drive pulley is engaged inside the slide groove of the slide rail, and the conductor bracket is installed at the bottom of the drive pulley.

[0012] Furthermore, a micro servo motor is installed on one side of the drive pulley, and the output shaft of the micro servo motor is fixedly connected to the wheel axle of the drive pulley. The outer wall of the drive pulley is provided with an anti-slip rubber layer, and several sets of guide wheels are installed at the bottom of the guide frame, and the outer wall of the guide wheels is provided with an arc-shaped groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the yarn tension adjusting device for knitting gloves is reasonable and has the following advantages: (1) Through the coordinated operation of the drive motor, gear transmission structure, and twisted baran tension gyroscope in the tension adjustment assembly, a closed-loop adjustment system is formed to achieve high-precision control of yarn tension. The drive motor starts after receiving the signal feedback from the tension sensor, and its output shaft drives the drive gear to rotate at a constant speed. The drive gear converts the rotational motion into the linear motion of the rack through meshing with the rack, which in turn drives the reduction gear meshing with it to rotate. Since the number of teeth of the reduction gear is many times that of the drive gear, this gear ratio can achieve a 1:3 reduction and torque increase effect, which greatly reduces the speed of the twisted baran tension gyroscope and increases the torque, laying the foundation for precise adjustment. The basic structure involves a reduction gear whose output is connected via a key to drive a twisting bar tension gyroscope. During rotation, a stable inertial torque is generated. When the yarn passes over the outer wall of the gyroscope, the tension damping formed by the rotational inertia and tilt angle of the gyroscope acts on the yarn in real time. When the tension needs to be increased, the drive motor rotates forward to accelerate the gyroscope speed, increasing the inertial torque and the damping force on the yarn. When the tension needs to be reduced, the drive motor rotates in reverse to decelerate the gyroscope speed, reducing the inertial torque and the damping force. This allows for micron-level fine-tuning of the yarn tension, enabling flexible adaptation to different materials and varying tension requirements of yarns of different thicknesses. (2) By adopting a linkage adjustment structure of "motor-pulley-rail" in the conductor assembly, the dynamic adaptation of the yarn transmission path is realized: the drive pulley slides back and forth along the rail under the precise drive of the micro servo motor. The micro servo motor can adjust the speed and direction in real time according to the winding position of the yarn on the take-up shuttle, and drive the conductor frame to move synchronously. The arc-shaped groove conductor wheels at the bottom of the conductor frame can form a stable wrapping guide for the yarn. The anti-slip rubber layer on the outer wall of the drive pulley increases the friction with the rail groove, avoiding jamming or slipping when the pulley slides, and ensuring the smooth movement of the conductor frame. The ceramic wear-resistant layer pasted on the inner wall of the arc groove of the conductor wheel can not only reduce the friction coefficient between the yarn and the groove and reduce yarn wear, but also prevent the yarn from jumping or deviating due to centrifugal force during high-speed transmission through the constraint of the arc surface. Under the synergistic effect of the three, the yarn always stays on the preset transmission path, effectively avoiding the problems of yarn entanglement and tension change in the traditional fixed conductor structure, and further improving the stability and continuity of yarn transmission.

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.

[0018] A yarn tension adjusting device for knitting glove production includes a base 1, a turntable 2 mounted on the top of the base 1, a take-up shuttle 3 engaged with the top of the turntable 2, a spring buckle 4 mounted on the top of the turntable 2, a feed shuttle 5 mounted on the top of the turntable 2, a bracket 6 fixedly connected to the outer wall of the base 1, a tension adjusting component 7 mounted on the top of the bracket 6, a wire assembly 8 mounted on the top of the base 1, a winding motor 9 mounted on the top of the base 1, and a belt roller 10 fixedly connected to the output shaft of the winding motor 9 via a coupling. A belt 11 is provided on the outer side of the belt roller 10.

[0019] The above structure uses a take-up motor 9 to drive the take-up shuttle 3 to rotate via belt roller 10 and belt 11. The unwind shuttle 5 and the take-up shuttle 3 are driven by belt 11 to achieve speed matching, reducing tension fluctuations during the take-up and unwinding process. At the same time, the spring buckle 4 can securely lock the take-up shuttle 3 onto the turntable 2 to prevent the take-up shuttle 3 from loosening during rotation.

[0020] Furthermore, the wire feeding shuttle 5 is fixedly installed above another set of turntables 2 by bolts, the wire taking shuttle 3 is connected to another set of belt rollers 10, and the belt rollers 10 are connected to the other belt rollers 10 through belt 11.

[0021] The above structure reduces tension fluctuations by ensuring the rotational speed matching of the take-up and unwinding mechanisms.

[0022] Furthermore, the tension adjustment assembly 7 internally includes a drive motor 701, a drive gear 702, a rack 703, a reduction gear 704, and a twisted baran tension gyroscope 705. The drive motor 701 is mounted on the outer wall of the bracket 6. The output shaft of the drive motor 701 is fixedly connected to the drive gear 702 via a coupling. The reduction gear 704 is mounted on the top of the bracket 6. The rack 703 is meshed with the outer wall of the reduction gear 704. The output end of the reduction gear 704 is fixedly connected to the twisted baran tension gyroscope 705. The drive gear 702 is meshed with the reduction gear 704 via the rack 703. The size of the reduction gear 704 is larger than that of the drive gear 702. The twisted baran tension gyroscope 705 is provided with a tilting gyroscope and a rotating shaft structure, and the tilt angle of the gyroscope is 30°.

[0023] The above structure precisely adjusts the yarn tension by utilizing the rotational inertia and tilt angle changes of the gyroscope.

[0024] Furthermore, the wire assembly 8 includes a slide rail 801, a drive pulley 802, and a wire frame 803. The top of the bracket 6 is fixedly connected to the slide rail 801. The drive pulley 802 is engaged inside the slide groove of the slide rail 801. The wire frame 803 is installed at the bottom of the drive pulley 802. A micro servo motor is installed on one side of the drive pulley 802, and the output shaft of the micro servo motor is fixedly connected to the wheel axle of the drive pulley 802. The outer wall of the drive pulley 802 is provided with an anti-slip rubber layer. Several sets of wire wheels are installed at the bottom of the wire frame 803, and the outer wall of the wire wheels is provided with an arc-shaped wire groove.

[0025] The above structure achieves stable yarn transmission, avoiding deviation and tangling.

[0026] Working principle: When in use, firstly, the yarn spool to be used is installed on the pay-off shuttle 5. One end of the yarn passes through the guide wheel of the guide assembly 8 and the twisting bar tension gyroscope 705 of the tension adjustment assembly 7 in sequence, and is finally fixed on the take-up shuttle 3. Start the take-up motor 9. The take-up motor 9 drives the take-up shuttle 3 to rotate through the belt roller 10 and the belt 11. The take-up shuttle 3 winds up the yarn, and at the same time, the pay-off shuttle 5 rotates synchronously with the take-up shuttle 3 to pay off the yarn.

[0027] Secondly, when the tension sensor detects that the yarn tension is too high, it transmits a signal to the take-up motor 9, which reduces its speed. At the same time, the drive motor 701 starts, driving the drive gear 702 to rotate. The drive gear 702 drives the reduction gear 704 to rotate through the rack 703. The reduction gear 704 drives the twisted ball tension gyroscope 705 to rotate, adjusting the tilt angle of the gyroscope and reducing the tension on the yarn. When the tension sensor detects that the yarn tension is too low, the take-up motor 9 increases its speed, the drive motor 701 rotates in the opposite direction, and the twisted ball tension gyroscope 705 adjusts its tilt angle to increase the yarn tension. Finally, during yarn transmission, a micro servo motor drives pulley 802 to slide along slide rail 801, moving conductor frame 803 to ensure that the yarn is always transmitted within the arc-shaped groove of the conductor wheel, avoiding deviation and tangling. It will be apparent to those skilled in the art that this invention is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
