[0002] Twisting is a core process in the textile industry, and its working principle is to combine multiple single yarns into a twisted yarn to enhance the strength, wear resistance and uniformity of the yarn. Traditional thread changing requires manual disassembly of full bobbins, arrangement of thread ends, installation of new bobbins and rethreading, which is cumbersome and time-consuming. Moreover, after disassembly of the bobbins, the core difficulty is to cut and fix the thread ends. In the prior art, the thread ends are usually fixed by simple cutting or manual winding. At this time, the cut thread ends lack a reliable fixing mechanism and are prone to loose and disordered due to vibration during transportation of the bobbins.

[0003] Therefore, it is necessary to provide an automatic lifting conveying device for thread changing of a twisting machine to solve the above problems. SUMMARY

[0019] In the embodiments of the present application, an automatic lifting and conveying device for changing thread in a twisting machine is provided, which is used for disassembling a thread drum 12 of a twisting machine 1. The lifting and conveying device 2 comprises: a sky rail 21 horizontally laid above the thread drum 12; a crown block 22 movably arranged on the sky rail 21, and the crown block 22 has a height adjusting end; a clamping wire arrangement 26 arranged on the height adjusting end, the clamping wire arrangement 26 comprises: a disc body 261, at least one telescopic assembly is arranged on the side of the disc body 261; a bidirectional telescopic cylinder 264 fixed to the bottom of the disc body 261, and a clamping jaw 265 is connected to the output end of the bidirectional telescopic cylinder 264; A wire arrangement assembly 269 is arranged at the telescopic end of the telescopic assembly, which is used to cut the wire body on one side of the wire drum 12 after the wire drum 12 is clamped by the clamping jaw 265, so that the wire head near one side of the wire drum 12 is attached to the wire drum 12.

[0020] Among them, the bidirectional telescopic cylinder 264 can be any one of a hydraulic cylinder or a pneumatic cylinder: Hydraulic cylinder: bidirectional telescopic through hydraulic system, provides high clamping force, ensures that the wire drum 12 does not slip during disassembly.

[0021] Pneumatic cylinder: bidirectional movement controlled by air pressure, quick action, suitable for frequent start-stop clamping operation.

[0022] In this embodiment, the output end of the bidirectional telescopic cylinder 264 directly drives the clamping jaw 265 to realize the function of clamping and releasing the wire drum 12.

[0023] In addition, the overhead rail 21 is horizontally laid above the wire drum 12 to provide a stable moving path for the whole device. The overhead traveling crane 22 is movably arranged on the overhead rail 21 and can slide horizontally along the overhead rail 21, so as to transport the clamping and arranging assembly 26 to a position above the wire drum 12 to be disassembled. The height adjusting end of the overhead traveling crane 22 can move up and down to make the clamping and arranging assembly 26 approach or move away from the wire drum 12, thereby realizing lifting and conveying.

[0024] In the implementation, when the height adjusting end positions the clamping and arranging assembly 26 near the wire drum 12, the bidirectional telescopic cylinder 264 is started to drive the clamping jaw 265 to perform bidirectional telescopic movement, so as to ensure that the wire drum 12 is clamped firmly and prepare for subsequent disassembly and wire arrangement operation. After the clamping jaw 265 clamps the wire drum 12, the wire arrangement assembly 269 is positioned to the wire body position on the side of the wire drum 12 through the telescopic action of the telescopic assembly. The cutting operation is performed, and at the same time, the wire arrangement assembly 269 presses or attaches the wire head near one side of the wire drum 12 to the surface of the wire drum 12 after cutting, so as to prevent the wire head from being loose or entangled, thereby facilitating subsequent processing or transportation.

[0025] In this embodiment, the top of the disc body 261 is fixed with a motor 262, and the motor 262 is fixed to the height adjusting end. A rotating seat 263 is rotatably arranged on the disc body 261, and the telescopic assembly is fixed on the rotating seat 263. A base cylinder 267 extends radially along the rotating seat 263; A sliding arm 268 is slidably arranged in the base cylinder 267, and the sliding arm 268 serves as a telescopic end of the telescopic assembly. Among them, one end of the sliding arm 268 away from the base cylinder 267 is provided with the wire arrangement assembly 269; The motor 262 is used to drive the rotating seat 263 to rotate.

[0026] In addition, the bottom of the slide arm 268 is fixed with a limiting post, and the disc body 261 is provided with a guide groove 266, and the limiting post extends into the guide groove 266. The guide groove 266 is configured to drive the slide arm 268 to slide along the axial direction of the base cylinder 267 when the limiting post moves along the guide groove 266.

[0027] The motor 262 is fixed on the top of the disc body 261 and directly drives the rotating seat 263 to rotate. The rotating seat 263 is arranged on the disc body 261, so that when the motor 262 is started, the rotating seat 263 rotates around the central axis of the disc body 261.

[0028] The motor 262 can be any one of a servo motor or a stepping motor. The servo motor can provide high-precision control (such as angle and speed adjustment), and is suitable for scenarios requiring precise positioning; the stepping motor has simple structure and low cost, and is suitable for step-by-step rotation operation. Regardless of the type, the rotation of the motor 262 provides a power source for the movement of the wire arrangement assembly 269.

[0029] In the embodiment, the telescopic assembly is fixed on the rotating seat 263 and includes the base cylinder 267 and the slide arm 268. The slide arm 268 serves as the telescopic end of the telescopic assembly, and the end of the slide arm 268 is provided with the wire arrangement assembly 269. Specifically, the end of the slide arm 268 is threadedly connected with the wire arrangement assembly 269, so that the distance between the wire arrangement assembly 269 and the base cylinder 267 in the initial state can be changed by pre-rotation adjustment to adapt to the size of the wire drum.

[0030] When the rotating seat 263 rotates, the entire telescopic assembly rotates with it. This enables the wire arrangement assembly 269 to perform circumferential motion around the axis of the wire drum 12 to approach the wire body on one side of the wire drum 12. Moreover, when the rotating seat 263 rotates, the limiting post is forced to move along the path of the guide groove 266. Due to the geometric constraints of the guide groove 266, the movement of the limiting post drives the slide arm 268 to slide along the axial direction of the base cylinder 267.

[0031] The guide groove 266 can be configured as a spiral groove or a wave-shaped groove. For example, the spiral groove causes the limiting post to produce radial displacement when the rotating seat 263 rotates, thereby pushing the slide arm 268 to slide outward or inward; the wave-shaped groove triggers the telescopic movement of the slide arm 268 at a specific angle. This mechanical linkage does not require an additional driver and relies on the shape of the groove to achieve precise control.

[0032] In the embodiment, the wire arrangement assembly 269 includes: a base 2691 threadedly connected to the telescopic end of the telescopic assembly; a telescopic rod 2692 fixedly installed in the base 2691, and the bottom of the telescopic rod 2692 is fixed with a mounting plate 2693; A micro conveyor belt 2696 is arranged on one side of the mounting plate 2693; The micro conveyor belt 2696 and the side of the mounting plate 2693 close to each other are provided with four elastic pads arranged in a rectangular distribution, and two corresponding elastic pads are connected with a first telescopic device 2695.

[0033] In implementation, when the bobbin is clamped by the clamping jaw 265, the micro conveyor belt 2696 is close to the thread area of the bobbin surface and rotates at a controllable speed to continuously pull and smooth the loose thread to the surface of the bobbin by friction. The first telescopic device 2695 is connected between the micro conveyor belt 2696 and the mounting plate 2693, and its core function is to dynamically adjust the orientation of the micro conveyor belt 2696: When the thread position deviates or the curvature of the bobbin surface changes, the first telescopic device 2695 telescopes in real time to push the micro conveyor belt 2696 to make a small angle deflection around the base 2691; this deflection ensures that the micro conveyor belt 2696 always fits the thread at the best angle, ensuring that the friction direction accurately points to the winding path of the bobbin, avoiding thread slipping or wrinkling.

[0034] In this embodiment, the mounting plate 2693 is provided with a lubricating roller 2694 close to the micro conveyor belt 2696, and a pressure sensor is arranged between the lubricating roller 2694 and the mounting plate 2693.

[0035] In addition, the bobbin 12 is provided with a thread leading mechanism 11 on one side, and the thread leading mechanism 11 is provided with an electrostatic sensor; When the micro conveyor belt 2696 presses the thread, the micro conveyor belt 2696 adjusts the number of revolutions according to the detection data of the electrostatic sensor.

[0036] In this embodiment, when one side of the micro conveyor belt 2696 presses the thread, the other side of the micro conveyor belt 2696 contacts the lubricating roller 2694, and the pressure sensor monitors the contact pressure in real time. When the micro conveyor belt 2696 moves, the lubricating roller can release a small amount of lubricating paste to the surface of the micro conveyor belt 2696, and the lubricating paste is evenly applied to the thread and the nearby thread body by the rotation of the micro conveyor belt 2696, forming a low-friction adhesion layer.

[0037] In addition, the thread leading mechanism 11 on one side of the bobbin 12 integrates the electrostatic sensor, which detects the change of static electricity in the thread area throughout the process. If the charge exceeds the preset threshold, the number of revolutions of the micro conveyor belt 2696 is increased, and the insulating property of the lubricating paste continuously inhibits the regeneration of static electricity, fundamentally solving the industry problem of thread falling off and providing a high-robustness technical solution for unmanned thread changing of the twisting machine.

[0038] In the embodiment, the telescopic rod 2692 is configured to reciprocate when the micro conveyor belt 2696 presses the thread end while the micro conveyor belt 2696 is working.

[0039] When the micro conveyor belt 2696 presses the thread end and starts rotating, the telescopic rod 2692 synchronously reciprocates. The reciprocation drives the mounting plate 2693 and the micro conveyor belt 2696 to vertically displace, and forms a composite force field with the horizontal friction force formed by the rotation of the micro conveyor belt 2696. The thread end is repeatedly rubbed under the action of the bidirectional force, and gradually penetrates into the natural gap of the thread body on the surface layer of the thread cylinder. The synchronously injected lubricating paste uniformly penetrates the gap between the thread bodies in the rubbing, and forms a flexible adhesive layer after solidification, which completely eliminates the risk of thread end rebound.

[0040] In the embodiment, the mounting plate 2693 is further provided with a cutting knife 2698 at one side, and a second telescopic device 2697 is further arranged between the mounting plate 2693 and the cutting knife 2698.

[0041] When the micro conveyor belt 2696 rotates and presses the thread body to the surface of the thread cylinder 12, the second telescopic device 2697 is activated to elongate and push the cutting knife 2698 to feed in the direction of the thread body. The cutting knife 2698 contacts the thread body that is tightened at a preset angle, and instantaneously completes the cutting action to form a thread end. After cutting, the second telescopic device 2697 immediately retracts to drive the cutting knife 2698 to separate from the thread body area, so as to avoid interfering with the subsequent thread arranging operation.

[0042] In the embodiment, the bottom of the crown block 22 is fixed with a vertically extending slide rail 23, and a sliding seat 24 is slidingly arranged on the slide rail 23, which serves as a height adjusting end of the crown block 22. The crown block 22 is further provided with a winch 25 for adjusting the height of the sliding seat 24.

[0043] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
