Description

Technical Field

[0001] The utility model relates to the technical field of ring spinning machine manufacturing, in particular to a broken thread removing device for a ring spinning twisting device. Background Art

[0002] Ring spinning is one of the most commonly used processes in spinning production. It is a method of spinning fibers, such as cotton, linen or wool, to make yarn. The ring spinning frame has a device for twisting roving supplied from a roving frame to spin spun yarn and for winding the spun yarn onto a bobbin.

[0003] Twisting is a common technique used in ring spinning. Twist design influences the physical and mechanical properties and appearance of tows, yarns, and threads, significantly impacting the properties, appearance, and usability of the fabric. For staple yarns, twisting is essential for imparting strength and other properties. For filament yarns and ply yarns, twisting creates a compact structure that is less susceptible to lateral forces. Twisting can also create textured yarns and fancy yarns. The amount and direction of twist influence not only the feel and appearance of the fabric, but also its inherent quality. Combining twisting and untwisting creates false twist.

[0004] In a traditional twisting device, a motor drives a twisting belt to rotate around a synchronous wheel. The twisting belt is placed horizontally on the ring spinning machine. Friction is generated between a twisting belt that moves laterally and the yarn that moves longitudinally. The twisting belt rotating around the synchronous wheel will form two-sided contact with the yarn, with the first contact having a twisting effect and the second contact having an untwisting effect. In theory, the speed of each point on the twisting belt should be the same, but due to the large lateral span of the ring spinning machine (generally more than 10 meters, and some even reach tens of meters), actual tests have found that the speed of each point on the twisting belt varies. The speed near the motor end is greater than the speed far from the motor end. This will cause a deviation in the twisting force at both ends of the ring spinning machine, affecting the consistency of the yarn product.

[0005] In order to solve the above problems, a ring spinning twisting device has been developed that can improve the speed synchronization of each point of the twisting belt. The application number is CN202320942144.3, and the name is "A twisting device for a ring spinning machine". It has driving devices connected to the synchronous wheels. The two driving devices synchronously drive the twisting belt to rotate. The problem of speed differences at different positions of the twisting belt caused by unilateral drive is solved by setting driving forces at both ends of the twisting belt. However, in actual use, it was found that some broken threads would be entangled on the twisting belt during the spinning process. These broken threads moved to each spinning station as the twisting belt moved. These broken threads would affect the normal spinning and the spinning quality. When the broken threads accumulated into clumps, the spinning would not be able to proceed normally, and the machine would have to stop to deal with these broken threads, which seriously affected the production efficiency. Therefore, the ring spinning twisting device needs further improvement. Utility Model Content

[0006] The purpose of the utility model is to make up for the above-mentioned deficiencies and disclose to the public a broken thread removing device for a ring spinning twisting device which has a simple and reasonable structure and can effectively remove broken threads and improve the operating stability of a ring spinning machine.

[0007] The technical solution of the present utility model is achieved as follows:

[0008] A broken thread removal device for a ring spinning twisting device, wherein broken thread removal mechanisms are arranged at intervals along the twisting belt of the ring spinning twisting device, the broken thread removal mechanism includes a bracket that is detachably matched with the frame of the ring spinning machine, the bracket is provided with a guide wheel group, the twisting belt passes through the guide wheel group, and a winding roller is installed on the bracket next to the twisting belt.

[0009] The measures to further optimize this technical solution are:

[0010] As an improvement, a connecting arm is provided at the upper end of the bracket, and the winding roller is rotatably mounted on the connecting arm.

[0011] As an improvement, the connecting arm is rotatably connected to the bracket via a rotating shaft.

[0012] As an improvement, the connecting arm is provided with reinforcing ribs, which can increase the strength of the connecting arm.

[0013] As an improvement, the guide wheel assembly includes three parallel guide wheels, with an assembly cavity formed between adjacent guide wheels for the twisting belt to pass through. The guide wheels guide and support the twisting belt, preventing the long-span twisting belt from sagging due to gravity and moving away from the winding roller. This ensures that the winding roller can be positioned near the twisting belt to remove any broken threads from the twisting belt.

[0014] As an improvement, the outer periphery of the guide wheel is provided with a groove adapted to the twisting belt, and the twisting belt is embedded in the groove to prevent the twisting belt from being separated from the guide wheel.

[0015] As an improvement, a first bearing is provided between one end of the connecting arm and the rotating shaft.

[0016] As an improvement, a second bearing is provided between the other end of the connecting arm and the winding roller.

[0017] The arrangement of the first bearing and the second bearing can reduce the friction at the rotating connection and improve the flexibility of rotation.

[0018] As an improvement, the winding roller is a wool roller. The surface of the wool roller has a certain degree of roughness, and it can rotate rapidly along its own axis during the friction with the twisting belt. Using the wool roller as the winding roller can improve the success rate of removing broken threads.

[0019] The advantages of the utility model are:

[0020] The utility model discloses a broken thread removal device for a ring spinning twisting device. The structure is simple and reasonable. The broken thread removal mechanism is arranged at intervals. The broken thread removal mechanism includes a bracket, a guide wheel group, and a winding roller. As the twisting belt moves, the broken thread wound on the twisting belt passes through the winding roller, frictionally contacting the winding roller and generating electrostatic force, causing it to be wound around the winding roller, thereby achieving the purpose of removing the broken thread and ensuring stable operation of the ring spinning operation. The broken thread removal mechanism is also detachable as a whole, making it convenient to remove the broken thread wound on the winding roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] like Figures 1 to 5 As shown, a broken thread removal device is used for a ring spinning twisting device, and broken thread removal mechanisms are arranged at intervals along the twisting belt 1 of the ring spinning twisting device. The broken thread removal mechanism includes a bracket 3 that is detachably matched with the frame 2 of the ring spinning machine, and a guide wheel group 4 is provided on the bracket 3. The twisting belt 1 passes through the guide wheel group 4, and a winding roller 5 is installed on the bracket 3 next to the twisting belt 1.

[0033] A connecting arm 31 is provided at the upper end of the bracket 3 , and the winding roller 5 is rotatably mounted on the connecting arm 31 .

[0034] The connecting arm 31 is rotatably connected to the bracket 3 via a rotating shaft 32 .

[0035] The connecting arm 31 is provided with a reinforcing rib 31 a. The provision of the reinforcing rib 31 a can improve the strength of the connecting arm 31.

[0036] The guide wheel assembly 4 includes three guide wheels 41 arranged in parallel, and an assembly cavity 4a for the twisting belt 1 to pass through is formed between adjacent guide wheels 41.

[0037] The outer periphery of the guide wheel 41 is provided with a groove 41 a adapted to the twisting belt 1. The twisting belt 1 is embedded in the groove 41 a to prevent the twisting belt 1 from escaping from the guide wheel 41.

[0038] A first bearing 61 is provided between one end of the connecting arm 31 and the rotating shaft 32 .

[0039] A second bearing 62 is provided between the other end of the connecting arm 31 and the winding roller 5 .

[0040] The arrangement of the first bearing 61 and the second bearing 62 can reduce the friction at the rotation connection and improve the flexibility of rotation.

[0041] The winding roller 5 is a wool roller. The surface of the wool roller has a certain degree of roughness and can generate static electricity during the friction with the twisting belt 1. Using a wool roller as the winding roller 5 can improve the success rate of removing broken threads.

[0042] Working principle:

[0043] The twisting device is mounted on the frame 2 of the ring spinning machine. The twisting belt 1 of the twisting device is positioned across the ring spinning machine. The broken thread removal mechanism is fixed to the frame 2 at intervals along the direction of the twisting belt 1 using brackets 3. The twisting belt 1 is placed into the assembly cavity 4a formed between adjacent guide wheels 41. Because the connecting arm 31 is rotatably connected to the bracket 3 via a rotating shaft 32, the weight of the connecting arm 31 causes the outer end of the connecting arm 31 to naturally droop. The winding roller 5 is rotatably connected to the outer end of the connecting arm 31, allowing the winding roller 5 to rest on the twisting belt 1. Since the winding roller 5 can rotate, its installation does not affect the normal operation of the twisting device.

[0044] After the ring spinning machine and the twisting device are started, if there are broken threads entangled on the twisting belt 1, as the twisting belt 1 moves, these entangled broken threads will pass through the winding rollers 5 of each broken thread removal mechanism one after another. During this process, the broken threads will come into frictional contact with the winding rollers 5 and generate electrostatic force and be wound around the winding rollers 5, thereby achieving the purpose of removing the broken threads.

[0045] The broken thread removal mechanisms are arranged at intervals so that the broken thread entangled in a certain section of the ring spinning machine (between two broken thread removal mechanisms) can be removed when passing through the next broken thread removal mechanism, avoiding the impact on other spinning stations, avoiding the impact on spinning quality due to thread entanglement, and avoiding shutdown maintenance caused by excessive thread entanglement.

[0046] In addition, by using the bracket 3 that is detachably matched with the frame 2 of the ring spinning machine, the broken wire removal mechanism can be removed from the ring spinning machine as a whole, making it convenient to remove the broken wire wrapped around the winding roller 5.

[0047] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
