Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, specifically to an automatic yarn-hanging mechanism for a circulating warping machine. Background Technology

[0002] Before warping, a circulating warping machine typically requires preparatory work such as yarn bobbin arrangement, yarn traction, and yarn hanging. During the yarn hanging process, the yarn bobbins, yarn ends, or traction connectors need to be hung on the corresponding hanging rods so that subsequent yarns can enter the warping process according to the predetermined path. Since the yarn hanging stations of a circulating warping machine are often arranged continuously along the length of the machine, and some machines also have multi-layer or multi-row yarn hanging structures, there are a large number of yarn hanging points, requiring high consistency in the hanging positions and stability of the hanging rods.

[0003] In current warping production, yarn hanging is mostly done manually. Operators need to move along the side of the equipment one by one, hanging the yarn bobbins or yarn ends onto the corresponding hanging rods, and repeatedly confirming that the hanging position is correct. This method has problems such as high labor intensity, slow work cycle, and inconsistent hanging positions, which easily leads to mishanging, missed hanging, yarn crossing, or hanging rods not being reset. If an independent drive unit is installed at each yarn hanging station to drive the hanging rod to rotate, it will result in a large number of drive units, complex wiring, and difficult installation and maintenance, which is not conducive to long-term stable use in textile workshops.

[0004] Therefore, a clear, easy-to-manufacture, and easy-to-maintain automatic yarn-hanging mechanism for a circulating warping machine is needed. This mechanism should utilize the movement of the carrying trolley along a U-shaped groove. When the carrying trolley reaches the detachable base, the interaction between the rack, driven gear, transverse transmission rod, damped power bevel gear, and driven bevel gear drives the upright and hanging rod to rotate. This reduces the need for separate drive components at each yarn-hanging station, improving yarn-hanging efficiency and consistency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic yarn-hanging mechanism for a circulating warping machine, which solves the problems of low efficiency of manual yarn hanging, inconsistent hanging positions, and complex structures caused by separate driving of each yarn-hanging station.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic yarn-hanging mechanism for a circulating warping machine, comprising a U-shaped groove, a base, a carrying trolley, and a detachable base. The U-shaped groove is mounted on the base and is equipped with an L-shaped limiting rail and a side rack. The carrying trolley is equipped with an adapter wheel, a rack, a reduction servo motor, and a drive gear. The adapter wheel engages with the L-shaped limiting rail, and the drive gear meshes with the side rack. The detachable base is equipped with a transverse transmission rod, a driven gear, a damped drive bevel gear, a driven bevel gear, a vertical rod, and a hanging rod. When the carrying trolley moves to the detachable base, the rack meshes with the driven gear, driving the transverse transmission rod, the vertical rod, and the hanging rod to rotate.

[0007] Preferably, there can be multiple bases, which are spaced apart along the length of the U-shaped channel. The bases are connected to the U-shaped channel or the mounting base by fixing bolts. With the support of multiple bases, the U-shaped channel can maintain good straightness and stability during the movement of the trolley.

[0008] Preferably, the L-shaped limiting rail is arranged along the length of the U-shaped groove, and the adapter wheel is located at the bottom or side of the carrying trolley, and the adapter wheel moves along the L-shaped limiting rail. The L-shaped limiting rail and the adapter wheel cooperate with each other to prevent the carrying trolley from easily shifting laterally or swaying up and down when moving on the U-shaped groove.

[0009] Preferably, the carrier trolley is equipped with an external plate and a motor bracket. The external plate is connected to the side of the carrier trolley, and the geared servo motor is mounted on the external plate via the motor bracket. The drive gear is connected to the output end of the geared servo motor. When the geared servo motor is working, the drive gear meshes with the side rack, thereby driving the carrier trolley to move along the U-shaped groove.

[0010] Preferably, the rack is connected to the bottom of the carrying trolley by fastening bolts, with the rack teeth facing the driven gear. When the carrying trolley is not moved to the detachable base, the rack and driven gear do not drive each other; when the carrying trolley moves to the detachable base, the rack enters the meshing area of ​​the driven gear and drives the driven gear to rotate.

[0011] Preferably, the detachable base is equipped with a top limiting bearing, an inner adapter groove, and a side limiting bearing. The upright pole mates with the top limiting bearing, the transverse transmission rod mates with the side limiting bearing, and the inner adapter groove mates with the end of the damped power bevel gear. The top limiting bearing ensures smooth rotation of the upright pole, the side limiting bearing ensures smooth rotation of the transverse transmission rod, and the inner adapter groove engages with the damped power bevel gear to maintain the position of the hanging pole after rotation.

[0012] Preferably, there can be multiple hanging rods, which are spaced apart along the axial direction of the upright. When the upright rotates, the multiple hanging rods rotate synchronously, making it suitable for multi-layer or multi-point yarn hanging. The outer plate can also be provided with a clearance groove, which is located on one side of the power gear, side rack, or U-shaped groove, to reduce interference between the outer plate and adjacent structures.

[0013] This invention provides an automatic yarn-hanging mechanism for a circulating warping machine. It has the following beneficial effects:

[0014] 1. This invention drives the carrying trolley to move along the U-shaped groove through the meshing of the power gear and the side rack, and drives the hanging rod to rotate through the meshing of the rack and the driven gear. The movement of the carrying trolley can be used to complete the automatic reversal of the hanging rod, reducing the need for a separate drive unit for each yarn hanging station.

[0015] 2. This invention ensures the movement position of the carrying trolley by using L-shaped limiting rails and matching wheels, and ensures the rotational stability of the upright and transverse transmission rod by using top limiting bearings and side limiting bearings. This can reduce the risk of the carrying trolley swaying, unstable meshing of the rack and driven gear, and failure of the hanging rod to rotate into position.

[0016] 3. The detachable base of the present invention can be spaced along the length of the U-shaped groove, which is convenient for arrangement and maintenance according to the number of yarn hanging stations; the inner adapter groove cooperates with the damped power bevel gear, which helps to keep the hanging rod relatively stable after rotation and improves the reliability of yarn hanging operation.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example:

[0028] like Figures 1 to 3 As shown, an automatic yarn-hanging mechanism for a circulating warping machine according to this embodiment includes a U-shaped groove 1, a base 2, a carrying trolley 3, and a detachable base 4. The U-shaped groove 1 extends along the yarn-hanging direction of the warping machine, and the length direction of the U-shaped groove 1 is consistent with the arrangement direction of the multiple yarn-hanging stations. The U-shaped groove 1 can be a long groove-shaped structure, with an L-shaped limiting rail 101 on its inner or upper side and a side rack 102 on its side. Both the L-shaped limiting rail 101 and the side rack 102 extend along the length direction of the U-shaped groove 1, allowing the carrying trolley 3 to move along the U-shaped groove 1 in a restricted position.

[0029] The base 2 is located below or to the side of the U-shaped groove 1. Multiple bases 2 are spaced apart along the length of the U-shaped groove 1, and are connected to the U-shaped groove 1 or the mounting base via fixing bolts 201. The mounting base can be a warping machine frame, a ground foundation, or an auxiliary support frame. The function of the base 2 is to support the U-shaped groove 1, preventing it from bending or shifting when bearing the movement of the trolley 3 and when the rack 302 and driven gear 406 are engaged. The fixing bolts 201 facilitate installation and disassembly, and also allow for later adjustment of the position of the U-shaped groove 1.

[0030] The L-shaped limiting rail 101 on the U-shaped groove 1 is used to cooperate with the adapter wheel 301 on the carrier trolley 3. The L-shaped limiting rail 101 may have a lateral limiting surface and a vertical limiting surface. When the adapter wheel 301 rolls or slides along the L-shaped limiting rail 101, the lateral and vertical positions of the carrier trolley 3 are constrained. In this way, when the carrier trolley 3 moves to the detachable base 4, the rack 302 can enter the meshing area of ​​the driven gear 406 in a stable position, avoiding meshing misalignment caused by the shaking of the carrier trolley 3.

[0031] A side rack 102 is disposed on the side of the U-shaped groove 1, with the tooth surface of the side rack 102 facing the drive gear 307 on the carrier trolley 3. The side rack 102 can be integrally formed with the U-shaped groove 1, or it can be fixed to the U-shaped groove 1 by screws, pressure plates, or welding. The position of the side rack 102 needs to correspond to the position of the drive gear 307, so that the drive gear 307 can roll along the side rack 102 under the drive of the reduction servo motor 306, thereby driving the carrier trolley 3 to move.

[0032] like Figure 2 , Figures 6 to 8 As shown, the carrier trolley 3 is mounted on the U-shaped groove 1 and can move along the length of the U-shaped groove 1. The carrier trolley 3 is equipped with adapter wheels 301, racks 302, fastening bolts 303, external plates 304, motor brackets 305, geared servo motors 306, power gears 307, and clearance grooves 308. The adapter wheels 301 are located at the bottom or side of the carrier trolley 3 and engage with the L-shaped limit rails 101 to keep the carrier trolley 3 stable during movement.

[0033] An external plate 304 is connected to the side of the carrying trolley 3. A motor bracket 305 is connected to the external plate 304, and a geared servo motor 306 is mounted on the motor bracket 305. A drive gear 307 is connected to the output end of the geared servo motor 306, and the drive gear 307 meshes with the side rack 102. When the geared servo motor 306 rotates, the drive gear 307 moves along the side rack 102, and the carrying trolley 3 moves accordingly along the length of the U-shaped groove 1. The external plate 304 and the motor bracket 305 ensure a stable mounting position for the geared servo motor 306 and the drive gear 307, which helps to ensure the meshing accuracy of the drive gear 307 and the side rack 102.

[0034] A clearance groove 308 is provided on the outer plate 304 and located on one side of the drive gear 307, the side rack 102, or the U-shaped groove 1. The clearance groove 308 is used to avoid adjacent structures when the carrying trolley 3 moves along the U-shaped groove 1, preventing interference between the outer plate 304 and the U-shaped groove 1, the side rack 102, or the drive gear 307. The clearance groove 308 also provides space for the assembly and adjustment of the drive gear 307 and the side rack 102, ensuring a suitable meshing clearance between them.

[0035] The rack 302 is connected to the bottom of the carrying trolley 3 by fastening bolts 303. The length direction of the rack 302 is consistent with the moving direction of the carrying trolley 3, and the tooth surface of the rack 302 faces the driven gear 406 on the detachable base 4. Since the rack 302 moves synchronously with the carrying trolley 3, when the carrying trolley 3 has not reached the detachable base 4, the rack 302 is disengaged from the driven gear 406; when the carrying trolley 3 moves to the detachable base 4, the rack 302 engages with the driven gear 406; when the carrying trolley 3 continues to move and leaves the detachable base 4, the rack 302 disengages from the driven gear 406 again.

[0036] like Figure 4 and Figure 5 As shown, the detachable base 4 is positioned beside or below the U-shaped groove 1, corresponding to the yarn hanging position on the U-shaped groove 1. The detachable base 4 can be installed on the U-shaped groove 1 or the mounting base via bolts, snap-fit ​​structures, or plug-in structures. The position of the detachable base 4 should ensure that the driven gear 406 and the rack 302 are at a suitable height and lateral distance for meshing. When multiple detachable bases 4 are spaced apart along the length of the U-shaped groove 1, the carrying trolley 3 can move along the U-shaped groove 1 and pass through multiple detachable bases 4 sequentially.

[0037] The detachable base 4 is equipped with a top limiting bearing 401, an inner adapter groove 402, and a side limiting bearing 403. The top limiting bearing 401 is located on the upper part of the detachable base 4, and the upright 408 cooperates with the top limiting bearing 401, allowing the upright 408 to rotate around its own axis on the detachable base 4. The side limiting bearing 403 is located on the side of the detachable base 4, and the transverse transmission rod 405 cooperates with the side limiting bearing 403, allowing the transverse transmission rod 405 to rotate relative to the detachable base 4. The top limiting bearing 401 and the side limiting bearing 403 respectively limit the position of the upright 408 and the transverse transmission rod 405, ensuring smooth rotation of both.

[0038] A driven gear 406 and a damped power bevel gear 404 are connected to the transverse transmission rod 405. The driven gear 406 is positioned to mesh with the rack 302. The driven gear 406 is fixedly connected to or synchronously connected to the transverse transmission rod 405, so that the transverse transmission rod 405 rotates synchronously when the driven gear 406 rotates. The damped power bevel gear 404 is also connected to the transverse transmission rod 405, so that the damped power bevel gear 404 rotates synchronously when the transverse transmission rod 405 rotates.

[0039] Driven bevel gear 407 is connected to the upright 408 and meshes with damped drive bevel gear 404. The axis of damped drive bevel gear 404 is aligned with or substantially aligned with the transverse transmission rod 405, and the axis of driven bevel gear 407 is aligned with or substantially aligned with the upright 408. Through the meshing of damped drive bevel gear 404 and driven bevel gear 407, the rotation of transverse transmission rod 405 can be converted into the rotation of upright 408. When upright 408 rotates, hanging rod 409 connected to upright 408 rotates synchronously.

[0040] The inner adapter groove 402 engages with the end of the damped power bevel gear 404. This engagement provides damping or positioning for the rotation of the damped power bevel gear 404, preventing the upright rod 408 and hanging rod 409 from freely rotating after reaching their predetermined positions due to the weight of the yarn bobbin, yarn tension, or equipment vibration. The inner adapter groove 402 can be located inside the detachable base 4, with the end of the damped power bevel gear 404 extending into or abutting against the inner adapter groove 402, thus forming a stable engagement.

[0041] Hanging rod 409 is connected to upright rod 408. There can be one or multiple hanging rods 409. In the illustrated embodiment, there are multiple hanging rods 409, spaced apart along the axial direction of upright rod 408 and extending laterally from upright rod 408. Multiple hanging rods 409 can rotate simultaneously with upright rod 408, suitable for simultaneously hanging multiple layers of yarn or multiple yarn bobbins. The hanging rod 409 and upright rod 408 can be connected by welding, screwing, or clamping, as long as the upright rod 408 rotates synchronously with the hanging rod 409.

[0042] After the geared servo motor 306 starts, the drive gear 307 rotates. Since the drive gear 307 meshes with the side rack 102, the drive gear 307 moves along the side rack 102 and drives the carrier trolley 3 to move along the U-shaped groove 1. During the movement of the carrier trolley 3, the adapter wheel 301 moves along the L-shaped limit rail 101, so that the carrier trolley 3 maintains a stable position.

[0043] When the carrying trolley 3 moves to a detachable base 4, the rack 302 at the bottom of the carrying trolley 3 enters the meshing area of ​​the driven gear 406. As the carrying trolley 3 continues to move, the rack 302 drives the driven gear 406 to rotate, the driven gear 406 drives the transverse transmission rod 405 to rotate, and the transverse transmission rod 405 drives the damped power bevel gear 404 to rotate. The damped power bevel gear 404 meshes with the driven bevel gear 407, thereby driving the driven bevel gear 407 and the upright 408 to rotate. After the upright 408 rotates, the hanging rod 409 rotates synchronously with the upright 408.

[0044] Through the above process, the linear movement of the carrying trolley 3 is sequentially transmitted through the rotation of the driven gear 406, the rotation of the transverse transmission rod 405, the meshing rotation of the damped power bevel gear 404 and the driven bevel gear 407, and the rotation of the upright rod 408 and the hanging rod 409. In other words, a continuous action coordination relationship is formed between the U-shaped groove 1, the carrying trolley 3, the rack 302, the driven gear 406, the transverse transmission rod 405, the damped power bevel gear 404, the driven bevel gear 407, the upright rod 408, and the hanging rod 409.

[0045] When the hanging rod 409 is rotated to a side that facilitates yarn hanging, the yarn bobbin, yarn end, or traction hook can be attached to the hanging rod 409. After the yarn is hung, the carrying trolley 3 can continue to move or move in the opposite direction, causing the rack 302 to drive the driven gear 406 to rotate again, thereby causing the upright rod 408 and the hanging rod 409 to rotate back to the direction required for subsequent warping. The rotation angle of the hanging rod 409 can be determined by the length of the rack 302, the number of teeth of the driven gear 406, and the meshing relationship between the damped power bevel gear 404 and the driven bevel gear 407.

[0046] When multiple detachable bases 4 are spaced apart along the length of the U-shaped groove 1, the carrying trolley 3 moves along the U-shaped groove 1, allowing the rack 302 to mesh sequentially with the driven gears 406 on the multiple detachable bases 4. Thus, when the carrying trolley 3 passes over one detachable base 4, it drives the hanging rod 409 on that detachable base 4 to rotate, and when it passes over the next detachable base 4, it drives the next hanging rod 409 to rotate. This structure allows multiple yarn-hanging stations to complete their actions sequentially via the same carrying trolley 3, reducing the need for a separate drive unit for each detachable base 4.

[0047] During assembly, the base 2 can be fixed on the mounting base first, and then the U-shaped groove 1 can be installed on the base 2 and fixed with fixing bolts 201. Then, the L-shaped limiting rail 101 and the side rack 102 are installed, so that the L-shaped limiting rail 101 and the side rack 102 are arranged along the length direction of the U-shaped groove 1. Subsequently, the carrying trolley 3 is installed on the U-shaped groove 1, so that the adapter wheel 301 engages with the L-shaped limiting rail 101, and the meshing state of the power gear 307 and the side rack 102 is adjusted.

[0048] When installing the carrier trolley 3, first connect the external plate 304 to the side of the carrier trolley 3, then install the motor bracket 305 onto the external plate 304, and install the geared servo motor 306 onto the motor bracket 305. After the drive gear 307 is connected to the output end of the geared servo motor 306, ensure that the drive gear 307 meshes properly with the side rack 102. The rack 302 is connected to the bottom of the carrier trolley 3 by fastening bolts 303. During installation, ensure that the tooth surface of the rack 302 faces the driven gear 406.

[0049] When installing the detachable base 4, first arrange the top limiting bearing 401, the inner adapter groove 402, and the side limiting bearing 403 in the corresponding positions of the detachable base 4. Then, mate the transverse transmission rod 405 with the side limiting bearing 403, and connect the driven gear 406 and the damped power bevel gear 404 to the transverse transmission rod 405. Next, mate the upright rod 408 with the top limiting bearing 401, and connect the driven bevel gear 407 to the upright rod 408, so that the driven bevel gear 407 meshes with the damped power bevel gear 404. Finally, connect the hanging rod 409 to the upright rod 408.

[0050] During debugging, the trolley 3 should be moved at low speed along the U-shaped groove 1 to observe whether the meshing of the drive gear 307 and the side rack 102 is smooth, and whether the engagement of the adapter wheel 301 and the L-shaped limit rail 101 is smooth. Then, the rack 302 should pass over the driven gear 406 to observe whether the rack 302 and the driven gear 406 can mesh and disengage smoothly. If the meshing position is off, the position of the detachable base 4 can be adjusted, or the position of the rack 302 at the bottom of the trolley 3 can be adjusted.

[0051] If the rotation angle of the hanging rod 409 is insufficient, the effective length of the rack 302 can be increased, or the meshing relationship between the driven gear 406, the damped power bevel gear 404, and the driven bevel gear 407 can be adjusted. If the rotation angle of the hanging rod 409 is too large, the effective length of the rack 302 can be shortened, or the meshing range between the driven gear 406 and the rack 302 can be adjusted. If the hanging rod 409 easily swings back after rotation, the meshing state between the inner adapter groove 402 and the damped power bevel gear 404 can be checked to ensure that they maintain appropriate damping.

[0052] When multiple detachable bases 4 are spaced apart along the length of the U-shaped groove 1, the moving sequence of the carrying trolley 3 corresponds to the arrangement sequence of the multiple detachable bases 4. The carrying trolley 3 first passes the first detachable base 4, where the rack 302 meshes with the driven gear 406 on that detachable base 4, causing the corresponding hanging rod 409 to rotate. When the carrying trolley 3 continues to move to the second detachable base 4, the rack 302 meshes with the driven gear 406 on the second detachable base 4. This process is repeated sequentially, allowing multiple yarn hanging stations to complete the rotation of the hanging rod 409 in turn.

[0053] The positional relationship between the hanging rod 409 and the upright rod 408 can be set according to the number of yarn layers. When there are multiple hanging rods 409, they are spaced apart along the axial direction of the upright rod 408, with each hanging rod 409 extending outward from the upright rod 408. Since multiple hanging rods 409 are connected to the same upright rod 408, a single rotation of the upright rod 408 can synchronously change the orientation of multiple hanging rods 409. This structure allows multiple yarn-hanging positions on the same detachable base 4 to simultaneously rotate from the side that is convenient for yarn hanging to the side required for warping work, and can also rotate back to the side that is convenient for yarn hanging when re-hanging is required.

[0054] The inner adapter groove 402 engages with the end of the damped power bevel gear 404 to maintain the position of the hanging rod 409 after it rotates. When the carrying trolley 3 passes the detachable base 4, the rack 302 drives the driven gear 406 to rotate, thereby causing the hanging rod 409 to rotate. When the rack 302 disengages from the driven gear 406, the hanging rod 409 is no longer driven by the carrying trolley 3. At this time, the engagement of the inner adapter groove 402 and the damped power bevel gear 404 reduces the possibility of the hanging rod 409 swinging freely back. This engagement is particularly suitable for situations where yarn bobbins or yarn ends are already hanging on the hanging rod 409.

[0055] The meshing between the damped power bevel gear 404 and the driven bevel gear 407 is used to change the direction of motion. The rotation direction of the transverse transmission rod 405 is different from that of the upright rod 408. After the damped power bevel gear 404 meshes with the driven bevel gear 407, the rotation of the transverse transmission rod 405 can be converted into the rotation of the upright rod 408 around its own axis. Since the hanging rod 409 is connected to the upright rod 408, the rotation of the upright rod 408 will drive the hanging rod 409 to rotate. The top limit bearing 401 cooperates with the upright rod 408, ensuring that the upright rod 408 maintains stable rotation even when the hanging rod 409 is subjected to the force of the yarn bobbin or yarn.

[0056] The transverse transmission rod 405 serves to connect the driven gear 406 and the damped power bevel gear 404 throughout the entire operation. The driven gear 406 connects to the transverse transmission rod 405, ensuring that the transverse transmission rod 405 rotates synchronously when the driven gear 406 is driven by the rack 302. Similarly, the damped power bevel gear 404 connects to the transverse transmission rod 405, ensuring that the damped power bevel gear 404 rotates synchronously when the transverse transmission rod 405 rotates. After the side limit bearing 403 engages with the transverse transmission rod 405, the position of the transverse transmission rod 405 on the detachable base 4 is relatively stable, and it is less prone to tilting due to the meshing of the rack 302 and the driven gear 406. This helps maintain the meshing state of the damped power bevel gear 404 and the driven bevel gear 407.

[0057] The detachable base 4, together with the transverse transmission rod 405, driven gear 406, damped power bevel gear 404, driven bevel gear 407, upright rod 408, and hanging rod 409, forms a complete yarn-hanging rotation structure. The detachable base 4 provides the mounting position. The transverse transmission rod 405 is supported by a side limiting bearing 403. The driven gear 406 is connected to the transverse transmission rod 405 and faces the rack 302. The damped power bevel gear 404 is also connected to the transverse transmission rod 405 and faces the driven bevel gear 407. The driven bevel gear 407 is connected to the upright rod 408, which engages with the top limiting bearing 401. The hanging rod 409 is connected to the upright rod 408. Thus, the rotation input from the rack 302 to the driven gear 406 can be transmitted along the transverse transmission rod 405, damped power bevel gear 404, driven bevel gear 407, and upright rod 408 to the hanging rod 409.

[0058] A fixed connection is formed between the rack 302, the fastening bolt 303, and the supporting trolley 3. After the rack 302 is installed at the bottom of the supporting trolley 3 via the fastening bolt 303, the rack 302 moves synchronously with the supporting trolley 3. The rack 302 and the driven gear 406 are not always engaged, but only when the supporting trolley 3 moves to the detachable base 4. After the front end of the rack 302 enters the tooth surface of the driven gear 406, the driven gear 406 begins to rotate; when the middle part of the rack 302 passes the driven gear 406, the driven gear 406 continues to rotate; after the rear end of the rack 302 leaves the driven gear 406, the driven gear 406 is no longer driven by the rack 302. This relationship allows one supporting trolley 3 to act sequentially on multiple detachable bases 4.

[0059] The side rack 102, the geared servo motor 306, and the drive gear 307 form a moving relationship for the carrier trolley 3. The geared servo motor 306 is mounted on the external plate 304 via a motor bracket 305. The external plate 304 is connected to the carrier trolley 3, thus keeping the geared servo motor 306 fixed relative to the carrier trolley 3. The drive gear 307 is mounted on the output end of the geared servo motor 306. After the drive gear 307 meshes with the side rack 102, the rotation of the geared servo motor 306 causes the drive gear 307 to move along the side rack 102, thereby driving the carrier trolley 3 to move along the U-shaped groove 1. The clearance groove 308 is located on the external plate 304. The clearance groove 308 corresponds to the position of the drive gear 307, the side rack 102, or the U-shaped groove 1, thus preventing the external plate 304 from affecting the meshing of the drive gear 307 and the side rack 102.

[0060] The engagement between the L-shaped limiting rail 101 and the adapter wheel 301 is primarily used to ensure the stability of the carrier trolley 3's movement. The adapter wheel 301 can contact either the horizontal or vertical portion of the L-shaped limiting rail 101. When the carrier trolley 3 is subjected to the reaction force of the rack 302 and the driven gear 406, the L-shaped limiting rail 101 can limit the adapter wheel 301 from deviating from its predetermined position. Thus, from the moment the carrier trolley 3 begins to approach the detachable base 4, until the rack 302 engages with the driven gear 406, and then until the rack 302 disengages from the driven gear 406, the carrier trolley 3 can maintain a relatively stable height and lateral distance, reducing meshing impact and meshing deviation.

[0061] To clarify the positional relationship between the U-shaped groove 1, the base 2, and the carrying trolley 3, the following further explanation is provided: The length direction of the U-shaped groove 1 is the direction of movement of the carrying trolley 3. Multiple bases 2 are distributed along the length direction of the U-shaped groove 1, and the bases 2 are fixed relative to the mounting base by fixing bolts 201. The carrying trolley 3 is located above, inside, or adjacent to the side of the U-shaped groove 1. The adapter wheel 301 is correspondingly set with the L-shaped limit rail 101, and the drive gear 307 is correspondingly set with the side rack 102. The rack 302 is located on the side that can access the driven gear 406. The above positional relationship allows the carrying trolley 3 to maintain its position by means of the adapter wheel 301, obtain movement power by means of the drive gear 307, and drive the driven gear 406 by means of the rack 302 when it reaches the detachable base 4.

[0062] The adapter wheel 301 can be a roller or a wheel with bearings; the rack 302 and the side rack 102 can be metal racks, or engineering plastic racks depending on the load; the driven gear 406, the damped power bevel gear 404, and the driven bevel gear 407 can be metal gears or wear-resistant gears. The selection of the above materials and processing methods does not change the positional relationship, connection relationship, and action relationship between the various reference numerals in this invention.

[0063] In this invention, the U-shaped groove 1 is used to limit the moving direction of the carrying trolley 3, the base 2 is used to support the U-shaped groove 1, the L-shaped limiting rail 101 and the adapter wheel 301 are used to ensure the moving stability of the carrying trolley 3, the side rack 102 and the drive gear 307 are used to drive the carrying trolley 3 to move, the rack 302 and the driven gear 406 are used to transmit the action when the carrying trolley 3 passes the detachable base 4, the transverse transmission rod 405, the damped drive bevel gear 404 and the driven bevel gear 407 are used to transmit the action to the upright rod 408, the upright rod 408 is used to drive the hanging rod 409 to rotate, and after the yarn hanging mechanism is installed on the top of the carrying trolley, it can realize the automatic yarn hanging of the circulating warping machine in conjunction with the above-mentioned components.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
