Description

Technical Field

[0001] This invention relates to the field of tension adjustment device technology, specifically to a tension adjustment device for longitudinal winding of covered yarn. Background Technology

[0002] In the longitudinal winding stage of covered yarn production, the tension adjustment device plays a crucial role in the winding quality. Existing related devices have limitations. For example, the tension adjustment device for longitudinal winding of covered yarn disclosed in patent document CN 222293260 U relies solely on the vertical displacement of the crossbar driven by the telescopic rod to adjust the tension of the covered yarn. It cannot achieve the movement and winding of the covered yarn in a direction perpendicular to the axis of the winding rod, leading to uneven distribution and looseness of the covered yarn on the winding rod during the winding process. This seriously affects the winding quality and product quality, thus necessitating improvements to the existing technology. Summary of the Invention

[0003] The present invention mainly provides a tension adjustment device for longitudinal winding of covered yarn, which solves the problems of existing technology that cannot realize the movement and winding of covered yarn in a direction perpendicular to the axis of the winding rod of the machine, resulting in uneven distribution and looseness of covered yarn on the winding rod during the winding process.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A tension adjustment device for longitudinal winding of covered yarn includes a machine housing, a winding rod on the machine housing, a lifting mechanism on the machine housing, a tension adjustment mechanism on the lifting mechanism, a vertical rod on the machine housing corresponding to the feed end of the tension adjustment mechanism, a mating wheel rotatably connected to the vertical rod, and anti-detachment rings on the upper and lower ends of the mating wheel.

[0006] The tension adjustment mechanism includes an adjustment frame mounted on the lifting mechanism, an adjustment motor mounted on the adjustment frame, an adjustment screw mounted on the output end of the adjustment motor, an adjustment guide rod mounted on the adjustment frame, the adjustment guide rod being axially parallel to the adjustment screw, an adjustment seat threadedly connected to the adjustment screw, the adjustment seat being slidably connected to the adjustment guide rod, a wheel frame mounted on the adjustment seat, an adjustment wheel rotatably connected to the wheel frame, and a limiting ring groove for engaging the covering yarn on the adjustment wheel. In use, the covering yarn is sequentially wound around the mating wheel and adjusting wheel, and then onto the winding rod. The lifting mechanism drives the tension adjustment mechanism to move back and forth along the axis of the winding rod. After the adjusting motor is started, it drives the adjusting screw to rotate. Since the adjusting seat is threadedly connected to the adjusting screw and slidably connected to the adjusting guide rod, the adjusting seat will move linearly along the adjusting guide rod when the adjusting screw rotates. The movement of the adjusting seat drives the wheel frame and adjusting wheel to move, thereby changing the position of the adjusting wheel. This allows for adjustment of the covering yarn tension in conjunction with the winding rod and the anti-slip wheel. The limiting ring groove can restrict the covering yarn to a specific position on the adjusting wheel, preventing it from slipping off from the top or bottom during the adjustment process. This structure, with the mating wheel serving as a transition component during the feeding of the covering yarn, reduces friction, allowing it to enter the tension adjustment mechanism more smoothly. Supported by the mating wheel, it works in conjunction with the tension adjustment mechanism to adjust the tension of the covering yarn. The anti-detachment ring prevents the covering yarn from detaching from the upper and lower ends of the mating wheel during the vertical movement of the tension adjustment mechanism driven by the lifting mechanism. Electric control of the adjusting screw allows for precise control of the movement distance and speed of the adjusting seat and adjusting wheel, achieving accurate adjustment of the covering yarn tension and reducing errors from manual operation. Through the coordinated work of the lifting mechanism and the tension adjustment mechanism, the dual functions of covering yarn tension adjustment and vertical winding are achieved. The lifting mechanism drives the tension adjustment mechanism up and down, causing the covering yarn to move back and forth in a direction perpendicular to the axis of the winding rod, effectively preventing concentrated distribution of the covering yarn on the winding rod and ensuring uniform winding, greatly improving the uniformity of winding.

[0007] Furthermore, an anti-detachment frame is detachably connected to the wheel frame, and an anti-detachment wheel is rotatably connected to the anti-detachment frame. The outer edge of the anti-detachment wheel has an annular boss for engaging with the limiting ring groove. The anti-detachment frame can be detachably connected to the wheel frame in any existing manner, as long as the corresponding technical principle is achieved. With this structure, the anti-detachment frame is mounted on the wheel frame, and the anti-detachment wheel can rotate freely on the anti-detachment frame. When the covering yarn is located within the limiting ring groove of the adjusting wheel, the annular boss on the outer edge of the anti-detachment wheel engages in the limiting ring groove, limiting the covering yarn. Working together with the limiting ring groove, this further prevents the covering yarn from detaching from the adjusting wheel. This double anti-detachment structure enhances the protection against detachment of the covering yarn.

[0008] Furthermore, the lifting mechanism includes a lifting frame mounted on the chassis, a lifting motor mounted on the lifting frame, a lifting screw mounted on the output end of the lifting motor, a lifting guide rod mounted on the lifting frame, a lifting seat threadedly connected to the lifting screw, and the lifting seat slidably connected to the lifting guide rod; the adjusting frame is mounted on the lifting seat. With this structure, after the lifting motor starts, it drives the lifting screw to rotate. The lifting seat is threadedly connected to the lifting screw and slidably connected to the lifting guide rod. When the lifting screw rotates, the lifting seat will move up and down linearly along the lifting guide rod. Since the adjusting frame is set on the lifting seat, the up and down movement of the lifting seat will drive the adjusting frame and the tension adjusting mechanism to move up and down as a whole, thereby changing the position of the covering yarn in the direction perpendicular to the axis of the winding rod of the machine box. The setting of the lifting mechanism allows the covering yarn to move vertically during the winding process, realizing the back and forth movement and winding of the covering yarn. This helps to distribute the covering yarn evenly on the winding rod, avoiding the problem of the covering yarn being concentrated in a certain area in the traditional winding method, improving the uniformity and quality of winding. Moreover, with the use of components such as the lifting screw, the movement of the lifting seat is more stable and accurate when driven by the lifting motor at a constant speed.

[0009] Furthermore, the wheel frame is detachably connected to the lifting base. With this structure, the detachable connection allows for easy removal of the wheel frame from the lifting base when it is necessary to replace, repair, or adjust the wheel frame or its connected components (such as adjusting wheels, anti-slip frames, etc.; replacing adjusting wheels means replacing different sizes of limit ring grooves). The wheel frame can then be reinstalled after the operation is complete.

[0010] Furthermore, the adjusting seat is provided with a connecting block, and the wheel frame is provided with a connecting groove into which the connecting block is inserted. The connecting block and the wheel frame are detachably connected by bolts. With this structure, during wheel frame installation, the connecting block is inserted into the connecting groove of the wheel frame to initially position the wheel frame and the adjusting seat. Then, the connecting block and the wheel frame are fastened together with bolts, achieving a stable connection between the wheel frame and the adjusting seat. When the wheel frame needs to be disassembled, simply unscrew the bolts to remove the connecting block from the connecting groove, completing the disassembly of the wheel frame. The cooperation between the connecting block and the connecting groove provides accurate positioning, ensuring the accuracy of the wheel frame's installation position, while the bolt connection ensures the stability of the connection, preventing displacement of the wheel frame during operation.

[0011] Beneficial effects: 1. The mating wheel, as a transition component during the feeding of the covering yarn, reduces the friction during feeding, allowing it to enter the tension adjustment mechanism more smoothly. Supported by the mating wheel, it works in conjunction with the tension adjustment mechanism to adjust the tension of the covering yarn. The anti-detachment ring prevents the covering yarn from detaching from the upper and lower ends of the mating wheel during the vertical movement of the tension adjustment mechanism driven by the lifting mechanism. 2. By electrically controlling the rotation of the adjusting screw, the movement distance and speed of the adjusting seat and adjusting wheel can be precisely controlled, thereby achieving accurate adjustment of the covering yarn tension and reducing errors from manual operation. 3. Through the coordinated work of the lifting mechanism and the tension adjustment mechanism, the dual functions of covering yarn tension adjustment and vertical winding are achieved. The lifting mechanism drives the tension adjustment mechanism to move up and down, allowing the covering yarn to move back and forth in a direction perpendicular to the axis of the winding rod, effectively preventing the covering yarn from being concentrated on the winding rod, ensuring uniform winding, and greatly improving the uniformity of winding.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a tension adjustment device for longitudinal winding of covered yarn in this embodiment includes a housing 1, a winding rod 2 is provided on the housing 1, a lifting mechanism 3 is provided on the housing 1, a tension adjustment mechanism 4 is provided on the lifting mechanism 3, a vertical rod 5 is provided on the housing 1 corresponding to the feeding end of the tension adjustment mechanism 4, a mating wheel 501 is rotatably connected to the vertical rod 5, and anti-detachment rings 502 are provided on the upper and lower ends of the mating wheel 501;

[0021] The tension adjustment mechanism 4 includes an adjustment frame 401 mounted on the lifting mechanism 3, and an adjustment motor 402 mounted on the adjustment frame 401. An adjustment screw 403 is mounted at the output end of the adjustment motor 402. An adjustment guide rod 404 is mounted on the adjustment frame 401, and the adjustment guide rod 404 is axially parallel to the adjustment screw 403. An adjustment seat 405 is threadedly connected to the adjustment screw 403, and the adjustment seat 405 is slidably connected to the adjustment guide rod 404. A wheel frame 406 is mounted on the adjustment seat 405, and an adjustment wheel 407 is rotatably connected to the wheel frame 406. The adjustment wheel 407 has a limiting ring groove 408 for engaging with the covering yarn. An anti-detachment frame 6 is detachably connected to the wheel frame 406, and an anti-detachment wheel 601 is rotatably connected to the anti-detachment frame 6. An annular boss 602 for engaging with the limiting ring groove 408 is provided on the outer edge of the anti-detachment wheel 601. The lifting mechanism 3 includes a lifting frame 301 mounted on the housing 1, a lifting motor 302 mounted on the lifting frame 301, a lifting screw 303 mounted at the output end of the lifting motor 302, a lifting guide rod 304 mounted on the lifting frame 301, a lifting seat 305 threadedly connected to the lifting screw 303, and a slidable connection between the lifting seat 305 and the lifting guide rod 304; an adjusting frame 401 is mounted on the lifting seat 305. A wheel frame 406 is detachably connected to the lifting seat 305. A connecting block is mounted on the adjusting seat 405, and a connecting groove 409 is mounted on the wheel frame 406 to accommodate the connecting block. The connecting block and the wheel frame 406 are detachably connected by bolts.

[0022] In use, the covering yarn is sequentially wound around the mating wheel 501 and the adjusting wheel 407, and then wound onto the winding rod 2. The lifting mechanism 3 drives the tension adjustment mechanism 4 to move back and forth along the axis of the winding rod 2. After the adjusting motor 402 is started, it drives the adjusting screw 403 to rotate. Since the adjusting seat 405 is threadedly connected to the adjusting screw 403 and slidably connected to the adjusting guide rod 404, the adjusting seat 405 will move linearly along the adjusting guide rod 404 when the adjusting screw 403 rotates. The movement of the adjusting seat 405 drives the wheel frame 406 and the adjusting wheel 407 to move, thereby changing the position of the adjusting wheel 407. This allows for the adjustment of the tension of the covering yarn with the cooperation of the winding rod 2 and the anti-detachment wheel 601. The limiting ring groove 408 can restrict the covering yarn to a specific position of the adjusting wheel 407 to prevent it from slipping off from the top and bottom sides during the adjustment process. This structure, with the mating wheel 501 serving as a transition component during the feeding of the covering yarn, reduces friction during feeding, allowing it to enter the tension adjustment mechanism 4 more smoothly. Supported by this structure, it works in conjunction with the tension adjustment mechanism 4 to adjust the tension of the covering yarn. The anti-detachment ring 502 prevents the covering yarn from detaching from the upper and lower ends of the mating wheel 501 during the vertical movement of the tension adjustment mechanism 4 driven by the lifting mechanism 3. The adjustment seat 405 can be precisely controlled by electrically controlling the rotation of the adjusting screw 403. The movement distance and speed of the adjusting wheel 407 are adjusted to achieve precise adjustment of the tension of the covering yarn, reducing errors caused by manual operation. Through the coordinated work of the lifting mechanism 3 and the tension adjusting mechanism 4, the dual functions of adjusting the tension of the covering yarn and vertical movement and winding are realized. The lifting mechanism 3 drives the tension adjusting mechanism 4 to move up and down, so that the covering yarn moves back and forth and is wound in a direction perpendicular to the axis of the winding rod 2 of the machine box 1. This effectively avoids the covering yarn being concentrated on the winding rod 2, ensuring that it is evenly wound and greatly improving the uniformity of winding.
