Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and more specifically, to a reciprocating cable winding and pulling device and its method of use. Background Technology

[0002] In cable processing, the take-up traction device typically performs the functions of continuous traction, guiding, and winding of the processed cables. Its operational status not only affects whether the cable can be successfully wound but also directly impacts the cable's tension stability, neatness of the winding, and the finished product's appearance. Especially for insulated cables, sheathed cables, and highly flexible wires, tension fluctuations, unstable guidance, or disordered winding during take-up can easily cause surface abrasions, localized tensile deformation, insulation damage, or uneven winding, thus affecting subsequent storage, transportation, testing, and usage. Therefore, achieving stable traction and uniform take-up of cables under continuous production conditions has always been a crucial aspect of cable processing equipment design.

[0003] In existing technologies, to ensure even cable distribution on the reel surface, a cable routing structure is typically required. The reciprocating motion of this structure guides the cables along the reel's axis, preventing cable accumulation in localized areas. While this method achieves cable routing to some extent, it still has significant shortcomings in practical applications. Particularly in some existing devices, the traction components, guiding components, or related structures need to reciprocate synchronously with the cable routing motion, resulting in a large overall mass of the components involved in the reciprocating motion and a high system inertia. When the device reaches the end of its travel and reverses direction, this significant inertia can easily cause impacts, vibrations, and noise, affecting not only the equipment's operational stability but also the tension stability during cable transport.

[0004] Furthermore, since the cable itself needs to maintain a relatively stable stress state during traction and winding, a large inertial disturbance during reciprocating motion can cause uneven traction speed, instantaneous tension fluctuations, or guide trajectory deviations within a short period. For cables with insulation or sheathing layers, these fluctuations can easily lead to tensile deformation, surface wear, or even localized damage, thereby reducing product consistency and appearance quality. For the equipment itself, frequent impacts and vibrations can also exacerbate fatigue wear on transmission components, guide components, and support components, shortening the equipment's service life. In other words, the current structure's method of "heavy components participating in reciprocating motion" often creates a conflict between the need for uniform cable laying and the need for stable traction.

[0005] In addition to the above, existing take-up devices commonly face another problem during the winding process: as take-up continues, the number of cable winding layers on the outside of the reel increases, and the outer diameter of the reel gradually increases, while the guide position of the cable before entering the reel is usually relatively fixed. In this case, the radial entry angle of the cable when entering the reel from the guide part will continuously change with the increase of the reel diameter. If the device lacks a compensation structure to match the change in reel diameter, it is difficult to maintain a consistent entry posture of the cable at different winding stages, which can easily lead to phenomena such as changes in cable pitch, localized cable stacking, skipped wires, overlapping wires, and uneven cable density. This problem is more prominent in processing scenarios with finer wire diameters, softer wires, or high requirements for take-up neatness.

[0006] From the perspective of the effectiveness of existing technologies, simply relying on conventional guide wheel arrangements or simple reciprocating cable winding actions often only solves the problem of "the cable can be wound up." However, it lacks an effective structural solution for the higher-level requirements of "maintaining relatively stable tension, a smooth guide path, a basically constant entry angle, and continuous uniform cable winding throughout the entire winding process." Especially under the complex working conditions of continuous reciprocating winding stroke and continuous change in the outer diameter of the cable reel, if both reciprocating motion inertia control and reel diameter change compensation cannot be taken into account simultaneously, the winding quality is often difficult to maintain consistently. Therefore, it is still necessary to provide a more structurally sound cable processing winding and traction device that can reduce inertial impact and tension fluctuations during the reversing process while achieving continuous cable traction and reciprocating cable winding. Furthermore, it should compensate for changes in the entry angle caused by the increase in the outer diameter of the cable reel winding, thereby improving problems such as uneven cable winding, cable skipping and overlapping, cable damage, and insufficient equipment operational stability in existing winding devices. Summary of the Invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0008] Therefore, the purpose of this invention is to provide a reciprocating take-up traction device for cable processing, including a traction mechanism, a cable laying mechanism, and a take-up mechanism.

[0009] The traction mechanism includes a set of traction wheels, the cable laying mechanism includes a set of first cable laying wheels, a reversing wheel for turning the cable 90°, and a set of second cable laying wheels.

[0010] The take-up mechanism includes a take-up drum, a reciprocating mechanism for driving the take-up drum to move horizontally, and a first fine-tuning mechanism and a second fine-tuning mechanism for controlling the descent of the drum frame. The first fine-tuning mechanism and the second fine-tuning mechanism have the same internal structure and are distributed in a reversed vertical mirror image.

[0011] The first fine-tuning mechanism includes a fixed box, a first wedge block located inside the fixed box, and a second wedge block that is movably disposed. A connecting plate is welded and fixed to the top of the first wedge block. The top of the connecting plate penetrates the wall of the fixed box. The top of the connecting plate on the first fine-tuning mechanism is connected to the take-up drum. The top of the connecting plate on the second fine-tuning mechanism is connected to the first fine-tuning mechanism.

[0012] As a preferred technical solution:

[0013] As described above, in a reciprocating take-up traction device for cable processing, the traction wheel, the first wire guide wheel, the reversing wheel, and the second wire guide wheel are all fixed to a fixed frame by bearings. The fixed frame is welded and fixed to a base. The axis of the first wire guide wheel is vertical, and the axis of the second wire guide wheel is horizontal.

[0014] Through the above technical solution, the distribution design of the first and second cable reels can ensure that after the cable turns 90°, the cable tension and conveying path are stable in both the vertical and horizontal directions, thus improving the cable winding quality.

[0015] As described above, a reciprocating take-up traction device for cable processing includes a base plate, a fixed side plate welded to one side of the base plate, and a movable side plate bolted to the other side of the base plate. One end of the take-up drum is connected to a bearing on the fixed side plate, and a shaft hole is provided on the movable side plate for the other end of the take-up drum to pass through. The bottom surface of the base plate is welded to the top of the connecting plate on the first fine-tuning mechanism.

[0016] With the above technical solution, one end of the take-up drum can be placed on the movable side plate. This not only ensures the smooth rotation of the take-up drum, but also allows the finished cable to be taken out after winding by removing and installing the movable side plate.

[0017] As described above, a reciprocating take-up traction device for cable processing has four rectangularly distributed guide posts running through the base plate. The bottom ends of the guide posts pass through the fixing box on the first fine-tuning mechanism and are fixed with bolts on the top wall of the fixing box on the second fine-tuning mechanism.

[0018] With the above technical solution, the guide columns are vertically distributed, which can guide the vertical movement of the base plate and the first fine-tuning mechanism, ensuring the accuracy of the vertical descent fine-tuning of the take-up drum.

[0019] As described above, in a reciprocating take-up traction device for cable processing, the bottom inclined surface of the first wedge and the top inclined surface of the second wedge are in contact with each other, the bottom surface of the second wedge has an inclined surface, the bottom inclined surface of the second wedge and the top inclined surface of the third wedge are in contact and slidably connected, the inclination angle of the inclined surface where the first wedge and the second wedge are in contact is greater than 3°, and the inclination angle of the inclined surface where the second wedge and the third wedge are in contact is less than or equal to 3°.

[0020] With the above technical solution, the second wedge supports the first wedge by means of an inclined surface. When the second wedge moves horizontally, the inclined surface support point descends. Under its own weight, the take-up drum causes the inclined surfaces of the first and second wedges to re-fit, thus achieving vertical fine adjustment of the take-up drum. Therefore, by controlling the horizontal displacement distance of the second wedge, the descent height of the take-up drum can be precisely controlled.

[0021] As described above, in a reciprocating cable winding and pulling device for cable processing, a set of first protrusions is integrally formed at the bottom end of the third wedge, a one-way rack is bolted to the outer wall of the third wedge between the two first protrusions, a first guide rod passes through the first protrusion, and the two ends of the first guide rod are welded and fixed to the inner wall of the fixing box.

[0022] Through the above technical solution, the third wedge can move horizontally along the first guide rod via a set of first protrusions, and thus the movement of the third wedge can drive the second wedge to move synchronously.

[0023] As described above, a reciprocating take-up traction device for cable processing includes a first fine-tuning mechanism that further includes a movable block located inside a fixed box. The bottom wall of the movable block is slidably connected to a guide rail, which is bolted to the inner wall of the bottom end of the fixed box. Movable rods are welded and fixed to both ends of the movable block. One end of the movable rod, which is not connected to the movable block, passes through the side wall of the fixed box and is flush with the side wall of the fixed box. One end of the movable rod is threadedly connected to an adjusting rod.

[0024] With the above technical solution, the adjusting rod and the movable rod can be freely disassembled and assembled. In this way, by rotating the adjusting rod of different lengths, the horizontal movement distance of the movable rod can be adjusted.

[0025] As described above, a reciprocating take-up traction device for cable processing has a set of fixed seats welded to the top wall of one end of the movable block. A shaft is welded between the two fixed seats. A pawl that cooperates with a one-way rack is sleeved on the shaft. Limiting rods are integrally formed at both ends of the pawl.

[0026] The shaft has retaining rings fitted at both ends with locking pins. The retaining rings have limiting grooves for the limiting rod to pass through. The retaining rings fit against the top wall of the limiting groove. The retaining rings are connected to the bottom wall of the limiting groove by an arc-shaped elastic spring.

[0027] With the above technical solution, the shaft and the pawl are connected by a bearing, and the pawl rotates through the shaft. The pawl, in conjunction with the one-way rack, can only achieve unidirectional movement of the third wedge.

[0028] As described above, a reciprocating take-up traction device for cable processing has a set of fixed seats welded to the top wall of one end of the movable block. A shaft is welded between the two fixed seats. A pawl that cooperates with a one-way rack is sleeved on the shaft. Limiting rods are integrally formed at both ends of the pawl.

[0029] The shaft is fitted with retaining rings at both ends. The retaining rings have retaining grooves for the retaining rod to pass through. The retaining rings fit against the top wall of the retaining groove. The retaining rings are connected to the bottom wall of the retaining groove by an arc-shaped elastic spring.

[0030] With the above technical solution, the shaft and the pawl are connected by a bearing, and the pawl rotates through the shaft. The pawl, in conjunction with the one-way rack, can only achieve unidirectional movement of the third wedge.

[0031] A method for using a reciprocating take-up traction device for cable processing includes the following steps:

[0032] S1. Slide the cable onto the take-up spool, then pass the free end of the cable to be processed through the traction wheel and the first cable reel in sequence. After turning 90°, pass it through the reversing wheel and the second cable reel in sequence, and finally fix it on the outside of the cable spool.

[0033] S2. Start the traction mechanism to deliver the cable at a constant speed. The take-up drum rotates to wind the cable. The take-up drum moves back and forth along the length of the equipment through the reciprocating mechanism to complete the uniform take-up of the cable.

[0034] S3. During the take-up process, the take-up drum gradually descends vertically during the reciprocating movement through the first and second fine-tuning mechanisms, ensuring that the radial entry angle of the cable remains constant throughout the entire process.

[0035] S4. After the cable is wound up, remove the movable side panel and pull the spool with the cable wound on it out of the take-up spool to complete the removal and placement of the finished cable.

[0036] S5. After unloading the finished cable, operate the take-up drum and the first fine-tuning mechanism to return to the initial position and start the next round of take-up operation.

[0037] Compared with the prior art, the present invention has at least the following beneficial effects:

[0038] (1) The present invention sets the traction mechanism and the cable guiding mechanism on a fixed frame, so that the traction wheel, the first cable guide wheel, the reversing wheel and the second cable guide wheel maintain stable position during the cable transportation process, and the reciprocating mechanism drives the take-up drum to reciprocate the cable along the length of the equipment. This changes the reciprocating motion object from the traditional traction / cable guide assembly to a lightweight component with the take-up end as the main component, which reduces the motion inertia and impact during reversal, which is conducive to maintaining the cable traction tension and the stability of the running path, thereby reducing equipment vibration, noise and cable stretching deformation, insulation layer wear and other problems, and improving the smoothness of the take-up process and the quality of the finished product.

[0039] (2) The present invention sets up a first fine adjustment mechanism and a second fine adjustment mechanism in the take-up mechanism, and adopts a wedge block force transmission structure arranged in reverse mirror image, combined with the unidirectional stepping action of the third wedge block, unidirectional rack and pawl, so that the take-up drum can generate a controlled micro vertical drop during each reciprocating reversal process; the drop is used to compensate for the increase in the outer diameter of the winding caused by the increase in the number of cable winding layers on the outside of the drum, so that the radial entry angle of the cable when it enters the drum from the guide end remains basically constant, reducing phenomena such as skipping, overlapping and uneven density of the cable, and improving the neatness of take-up and the consistency of processing.

[0040] (3) In this invention, the fixed guide path, the reciprocating winding of the take-up drum and the vertical fine-tuning compensation work together. On the one hand, the first winding wheel, the reversing wheel and the second winding wheel are used to realize the orderly conversion of the cable conveying direction. On the other hand, the guide column is used to constrain the lifting process of the take-up mechanism, so that the take-up drum maintains good motion accuracy during reciprocating movement and gradual descent, thereby ensuring that the cable is evenly arranged and the interlayer transition is smooth when it is continuously wound up. It is especially suitable for cable processing scenarios with high requirements for winding accuracy and surface quality. Attached Figure Description

[0051] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0052] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0053] like Figures 1-8 As shown in the figure, an embodiment of the present invention discloses a reciprocating take-up traction device for cable processing, including a traction mechanism, a cable laying mechanism and a take-up mechanism.

[0054] The traction mechanism includes a set of traction wheels 1, the cable laying mechanism includes a set of first cable laying wheels 2, a reversing wheel 3 for turning the cable 90°, and a set of second cable laying wheels 4. The traction wheels 1, the first cable laying wheels 2, the reversing wheel 3 and the second cable laying wheels 4 are all fixed to the fixed frame 6 by bearings. The fixed frame 6 is welded and fixed to the base 5. The axis of the first cable laying wheel 2 is vertical and the axis of the second cable laying wheel 4 is horizontal.

[0055] The take-up mechanism includes a take-up drum 7, a reciprocating mechanism for driving the take-up drum 7 to move horizontally, and a first fine-tuning mechanism and a second fine-tuning mechanism for controlling the descent of the drum frame. The first fine-tuning mechanism and the second fine-tuning mechanism have the same internal structure and are distributed in a mirror image with opposite vertical orientations.

[0056] The first fine-tuning mechanism includes a fixed box 14, a first wedge 13 located inside the fixed box 14, and a second wedge 15 that is movably set. A connecting plate 12 is welded and fixed to the top of the first wedge 13. The top of the connecting plate 12 penetrates the wall of the fixed box 14. The top of the connecting plate 12 on the first fine-tuning mechanism is connected to the take-up drum 7. The top of the connecting plate 12 on the second fine-tuning mechanism is connected to the first fine-tuning mechanism.

[0057] In practical implementation, the traction mechanism, as the power core of cable transportation, includes not only the traction wheel 1 for clamping the cable, but also a drive motor for rotating the traction wheel 1. This drive motor can achieve precise speed adjustment, thereby driving the traction wheel 1 to rotate at a constant speed, ensuring that the cable does not slip or fluctuate in speed during traction. At the same time, a swing-arm tension adjustment wheel is specially set on the fixed frame 6. This tension adjustment wheel forms a tension closed-loop control with the traction mechanism and the take-up mechanism. When the tension is too high or too low during cable traction, the swing-arm tension adjustment wheel will provide feedback signals through changes in the swing arm angle, indirectly adjusting the speed of the traction motor and the take-up motor, thereby compensating for the cable tension in real time and ensuring that the tension of the cable remains constant throughout the entire traction and take-up process.

[0058] Before starting the take-up operation, the cable clamping and threading preparations are completed. A suitable spool is fitted onto the take-up spool 7. The spool and the core shaft of the take-up spool 7 are fitted with a clearance fit, which ensures that the spool rotates synchronously with the take-up spool 7 during subsequent take-up and facilitates quick disassembly after take-up. Then, the free end of the cable to be processed is passed through the traction wheel 1 and the first cable tray 2 in sequence. After turning 90°, it is passed through the reversing wheel 3 and the second cable tray 4 in sequence. Finally, the free end of the cable is fixed on the outside of the spool.

[0059] After the threading preparation is completed, the drive motors on the traction mechanism and the take-up mechanism are started. The two drive motors are synchronized through the electronic control system to ensure that the traction speed and the take-up speed are precisely matched. Specifically, the drive motor of the traction mechanism drives a set of traction wheels 1 to rotate at a constant speed. Through the friction between the traction wheels 1 and the cable, the cable is smoothly transported at a preset constant speed. At the same time, the drive motor of the take-up mechanism drives the take-up drum 7 to rotate synchronously. During the rotation of the take-up drum 7, the transported cable is evenly wound around the outside of the drum, realizing the cable winding operation.

[0060] The take-up drum 7 moves in a reciprocating linear motion along the length of the equipment via a reciprocating mechanism. The reciprocating speed is linked and matched with the rotation speed of the take-up drum 7 to ensure that the cable is tightly arranged layer by layer on the upper drum.

[0061] During the reciprocating movement of the take-up drum 7 along the length of the equipment, as the number of cable winding layers increases, the outer diameter of the cable winding on the outside of the drum gradually increases. Each time the take-up drum 7 moves back and forth to the end of its stroke and completes the reversal, the second wedge 15 will move horizontally a certain distance, which will cause a small gap to be generated between the inclined surfaces of the second wedge 15 and the first wedge 13. At this time, the take-up drum 7, the drum, and the wound cable will begin to slowly descend under their own weight until the inclined surfaces of the first wedge 13 and the second wedge 15 are tightly pressed together again, and the take-up drum 7 stops moving vertically.

[0062] Through the above-mentioned cyclical action, after each layer of cable winding is completed and each reciprocating change of direction, the take-up drum 7 will automatically complete a small vertical descent adjustment. The descent amount is precisely matched with the outer diameter of the cable, thereby ensuring that the radial entry angle of the cable remains constant throughout the entire process, further improving the take-up accuracy. It is especially suitable for processing precision cables such as thin wires and soft wires.

[0063] When the cable on the take-up drum 7 is wound to the preset thickness, the drive motors of the traction mechanism and the take-up mechanism are turned off, the equipment stops running, and the unloading process begins.

[0064] After unloading the finished cable, manually operate the take-up reel 7 and the first fine-tuning mechanism to return to the initial working position, and at the same time put the new reel into the take-up reel 7. Repeat the above threading and starting steps to enter the next round of take-up operation and realize continuous production.

[0065] In one specific embodiment of the present invention, the take-up mechanism further includes a base plate 8, a fixed side plate 9 welded and fixed to one side of the base plate 8, and a movable side plate 10 bolted to the other side of the base plate 8. One end of the take-up drum 7 is connected to the fixed side plate 9 by a bearing. The movable side plate 10 has a shaft hole for the other end of the take-up drum 7 to pass through. The bottom surface of the base plate 8 is welded and fixed to the top of the connecting plate 12 on the first fine-tuning mechanism.

[0066] Specifically, such as Figures 1-3 As shown, the take-up drum 7 can rotate smoothly on the fixed side plate 9 and the movable side plate 10 to wind the cable. When it is necessary to unwind the wound cable, simply remove the movable side plate 10 on one side of the take-up drum 7. The movable side plate 10 can release the lateral restriction on the take-up drum. Without prying or pulling the cable, the take-up drum with the cable wound can be directly pulled out from the take-up drum 7 to complete the loading and unloading of the finished cable. The operation is convenient and efficient, avoiding problems such as tangled wires and damage to the finished cable.

[0067] When the inclined surfaces of the second wedge 15 and the first wedge 13 that are in contact with each other produce a small gap, the overall weight of the take-up drum 7 and the cable will be applied to the base plate 8, and the base plate 8 will then descend and drive the first wedge 13 to move through the connecting plate 12, so as to make the inclined surfaces of the first wedge 13 and the second wedge 15 fit together tightly again.

[0068] In one specific embodiment of the present invention, four rectangularly distributed guide posts 11 are passed through the base plate 8. The bottom ends of the guide posts 11 pass through the fixing box 14 on the first fine-tuning mechanism and are fixed to the top wall of the fixing box 14 on the second fine-tuning mechanism by bolts.

[0069] Specifically, such as Figure 3 and Figure 4 As shown, when the take-up drum 7 and the base plate 8 begin to descend under their own weight, they will move vertically along the guide column 11. When the first fine-tuning mechanism begins to descend under the weight of the take-up drum 7 and the base plate 8, it will also move vertically along the guide column 11, thereby improving the overall movement accuracy and ensuring that the fine-tuning distance of the take-up drum 7 remains constant each time it descends vertically.

[0070] In one specific embodiment of the present invention, the bottom inclined surface of the first wedge 13 and the top inclined surface of the second wedge 15 are in contact with each other. The bottom surface of the second wedge 15 has an inclined surface. The bottom inclined surface of the second wedge 15 is in contact with and slidably connected to the top inclined surface of the third wedge 16. The inclination angle of the inclined surface where the first wedge 13 and the second wedge 15 are in contact is greater than 3°, and the inclination angle of the inclined surface where the second wedge 15 and the third wedge 16 are in contact is less than or equal to 3°.

[0071] The bottom end of the third wedge 16 is integrally formed with a set of first protrusions 17. A one-way rack 19 is bolted to the outer wall of the third wedge 16 between the two first protrusions 17. A first guide rod 18 passes through the first protrusion 17. The two ends of the first guide rod 18 are welded and fixed to the inner wall of the fixing box 14.

[0072] Specifically, such as Figures 3-5 As shown, the overall weight of the take-up drum 7 and the cable is transferred to the second wedge 15 through the first wedge 13. The first wedge 13 transmits the force to the second wedge 15 through the steep incline, generating a large horizontal thrust. To prevent the second wedge 15 from being pushed by the horizontal thrust and to achieve self-locking, a third wedge 16 is provided. Since the second wedge 15 does not directly contact the first guide rod 18 and other components, the second wedge 15 will continue to transmit all the horizontal force downward to the third wedge 16. The inclination angle of the inclined surface where the second wedge 15 and the third wedge 16 are attached is less than the friction angle, forming a friction self-locking structure, which can effectively counteract the horizontal component force generated by the weight of the take-up drum 7, prevent the third wedge 16 from being forced to displace, and ensure the lifting and positioning accuracy.

[0073] Since the third wedge 16 will not move, the second wedge 15 will also be forcibly fixed, thus ensuring that the take-up drum 7 will not shift again after vertical descent and fine adjustment.

[0074] The bottom inclined surface of the second wedge 15 and the top inclined surface of the third wedge 16 can be slidably connected by a T-slot or a T-slider. In this way, the second wedge 15 and the third wedge 16 can only slide relative to each other along the inclined surface, without being misaligned or disengaged. This allows the horizontal force to be smoothly and stably transmitted from the second wedge 15 to the third wedge 16. Furthermore, when the third wedge 16 is actively driven to slide along the first guide rod 18, the third wedge 16 can drive the second wedge 15 to move synchronously.

[0075] In one specific embodiment of the present invention, the first fine-tuning mechanism further includes a movable block 21 located inside the fixed box 14. A guide rail 22 is slidably connected to the bottom wall of the movable block 21. The guide rail 22 is bolted to the inner wall of the bottom end of the fixed box 14. Movable rods 20 are welded and fixed to both ends of the movable block 21. One end of the movable rod 20 that is not connected to the movable block 21 passes through the side wall of the fixed box 14 and is flush with the side wall of the fixed box 14. An adjusting rod 30 is threadedly connected to one end of the movable rod 20.

[0076] A set of fixed seats 23 are welded and fixed to the top wall of one end of the movable block 21. A shaft 24 is welded and connected between the two fixed seats 23. A pawl 25 that cooperates with the one-way rack 19 is sleeved on the shaft 24. Limiting rods 28 are integrally formed at both ends of the pawl 25.

[0077] The shaft 24 has retaining rings 26 at both ends. The retaining rings 26 have a limiting groove 27 for the limiting rod 28 to pass through. The retaining rings 26 fit against the top wall of the limiting groove 27. The retaining rings 26 are connected to the bottom wall of the limiting groove 27 by an arc-shaped elastic spring 29.

[0078] Specifically, such as Figures 1-7 As shown, the adjusting rod 30 on the first fine-tuning mechanism faces the first upright plate 31, and the adjusting rod 30 on the second fine-tuning mechanism faces the second upright plate 32. When the take-up drum 7 moves toward the second upright plate 32, the adjusting rod 30 on the second fine-tuning mechanism will be squeezed, and the adjusting rod 30 will push the movable rod 20 to move horizontally, and the end of the movable block 21 away from the adjusting rod 30 will extend out.

[0079] The movable lever 20 will push the movable block 21 to move horizontally in a straight line. At this time, the pawl 25 is inserted into the tooth groove of the one-way rack 19. Since the fixed ring 26 is fixed, the limiting lever 28 is restricted by the limiting groove 27, so the pawl 25 will not rotate to push the one-way rack 19 to move.

[0080] The one-way rack 19 can drive the third wedge 16 to move, so the second wedge 15 moves synchronously and separates from the inclined surface of the first wedge 13. The first fine-tuning mechanism begins to descend under the weight of the take-up drum 7. The fixing box 14 on the first fine-tuning mechanism will drive the inclined surfaces of the first wedge 13 and the second wedge 15 to fit together again through the connecting plate 12. In this way, the first fine-tuning mechanism and the take-up drum 7 descend together to complete the fine-tuning.

[0081] When the take-up drum 7 moves toward the first upright plate 31, the adjusting rod 30 on the first fine-tuning mechanism will be squeezed by the first upright plate 31, and the movable rod 20 extending from the second fine-tuning mechanism will also be squeezed by the first upright plate 31. Repeating the above steps, the second wedge 15 in the first fine-tuning mechanism will separate from the inclined surface of the first wedge 13. Thus, under the action of the weight of the take-up drum 7, the inclined surfaces of the first wedge 13 and the second wedge 15 will be put into contact again, thus completing the vertical descent fine-tuning of the take-up drum 7.

[0082] When the movable rod 20 on the second fine-tuning mechanism is squeezed, it will push the movable block 21 to move in the opposite direction, and the adjusting rod 30 on the movable rod 20 will extend again. At this time, the pawl 25 will rotate on the shaft 24 and slide over the back of the tooth of the one-way rack 19, thus preventing the one-way rack 19 from moving and ensuring that the third wedge block 16 can only move in one direction.

[0083] When the pawl 25 rotates on the shaft 24, the shaft 24 will move in the limiting groove 27 and compress the spring spring 29. When the movable block 21 stops moving, the spring spring 29 will push the pawl 25 to insert into the tooth groove of the one-way rack 19.

[0084] In one specific embodiment of the present invention, the reciprocating mechanism includes a second protrusion 33, which is integrally formed with the bottom wall of the fixed box 14 on the second fine-tuning mechanism. A lead screw 34 threadedly connected to the second protrusion 33 passes through it, and a set of second guide rods 35 slidably connected to it also passes through it. Both ends of the lead screw 34 are bearing connected to the first upright plate 31 and the second upright plate 32. Both ends of the second guide rod 35 are welded to the first upright plate 31 and the second upright plate 32. The first upright plate 31 and the second upright plate 32 are parallel to each other and welded and fixed to the base 5.

[0085] Specifically, such as Figure 1 , Figure 2 and Figure 8 As shown, the reciprocating mechanism also includes a drive motor for driving the lead screw 34 to rotate. When the drive motor drives the lead screw 34 to rotate, the lead screw 34 can push the second protrusion 33 to move linearly along the second guide rod 35. The second protrusion 33 drives the second fine-tuning mechanism to move synchronously as a whole through the fixed box 14. The second fine-tuning mechanism drives the base plate 8 and the first fine-tuning mechanism to move synchronously through the guide column 11. In this way, the take-up drum 7 can reciprocate with the base plate 8 to wind up the cable.
