Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment technology, and in particular to a yarn breakage prevention mechanism for a twisting machine. Background Technology

[0002] As a crucial piece of equipment in the textile industry, the doubling machine plays a key role in the yarn twisting process. With the rapid development of the textile industry, the requirements for the production efficiency and product quality of doubling machines are becoming increasingly stringent. However, in the actual operation of doubling machines, yarn breakage is a common and serious problem.

[0003] Existing breakage prevention mechanisms in double twisters have several shortcomings. Some mechanisms have low detection sensitivity, failing to detect subtle signs of breakage in a timely manner; their response speed is slow, failing to quickly stop the breakage after it occurs, leading to yarn entanglement in equipment parts, resulting in material waste and cleaning difficulties; their reliability is poor, easily affected by workshop environmental factors, causing malfunctions or failures; maintenance costs are high, and the complex structure makes repair and replacement of parts difficult; their versatility is also poor, making them difficult to adapt to various models of double twisters. These problems seriously affect the stability and working efficiency of double twisters, hindering the smooth operation of textile production.

[0004] Therefore, developing a high-efficiency, reliable and easy-to-maintain wire breakage prevention mechanism for a two-twisting machine is of great practical significance.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Furthermore, the design of the support guide assembly and the impeding reset assembly makes the movement of the brake plates more stable and reliable, further improving the working efficiency and stability of the twisting machine.

[0037] Reference Figure 1-7A wire breakage prevention mechanism for a twisting machine includes a support frame 1, a pay-off roller 11, a take-up roller 12, a wire drum 2, and two brake plates 3. The pay-off roller 11, the wire drum 2, and the take-up roller 12 are all mounted on the support frame 1 and arranged sequentially from top to bottom. The two brake plates 3 are both mounted inside the wire drum 2 and are arranged symmetrically. Four strip blocks 31 are slidably mounted on the wire drum 2. The four strip blocks 31 are respectively fixedly connected to the corresponding brake plates 3. The side of the four strip blocks 31 away from the brake plates 3 extends to the outside of the wire drum 2 and is fixedly mounted with two parallel connecting plates 32, which can provide support and guidance for the brake plates 3.

[0038] Multiple fixing rods 332 are fixedly installed on the side of the two connecting plates 32 that are close to each other. Sleeves 331 are slidably sleeved on the multiple fixing rods 332. The multiple sleeves 331 are fixedly installed on the outside of the wire tube 2. The same spring 333 is fixedly installed on the inner wall of the sleeve 331 that is close to the wire tube 2 and the end of the fixing rod 332 that is close to the wire tube 2. This can quickly control the connecting plate 32 to move closer to the wire tube 2, so that the brake plate 3 can be controlled by the strip block 31 to quickly stop the wire passing through the wire tube 2.

[0039] The guide tube 2 has multiple mounting ports. Multiple iron pieces 35 are fixedly installed on the side of the two brake plates 3 that are far apart from each other. Mounting blocks 341 can be detachably installed in each of the multiple mounting ports. Electromagnets 34 are fixedly installed on the side of the multiple mounting blocks 341 that are close to the brake plates 3. The multiple electromagnets 34 are adapted to the corresponding iron pieces 35. They can control the two brake plates 3 to move in opposite directions by adsorption. At the same time, after the electromagnets 34 are de-energized, the two brake plates 3 can be controlled to quickly stop the wire passing through the guide tube 2 with the cooperation of components such as springs 333, strip blocks 31 and connecting plates 32. Multiple mounting slots are opened on the side of the two brake plates 3 that are far apart from each other. Multiple iron pieces 35 are embedded and fixedly installed in the corresponding mounting slots.

[0040] Specifically, in order to facilitate the disassembly and replacement of electromagnet 34 as needed, and to facilitate the operator to control the rotation of mounting block 341, mounting block 341 is provided with external threads, and internal threads are provided on the inner walls of multiple mounting ports. The external threads are adapted to the corresponding internal threads, and a handle is fixedly installed on the side of mounting block 341 away from electromagnet 34.

[0041] Specifically, in order to avoid abnormal friction between the wire and the end of the wire cylinder 2 when the wire enters and exits the wire cylinder 2, and to prevent the wire and debris from entering the side of the two brake plates 3 that are far apart from each other, guide rings 201 are fixedly installed at the top and bottom of the wire cylinder 2, and flexible guide plates 301 are fixedly installed on the top and bottom sides of the brake plates 3, and the end of the guide plate 301 away from the brake plate 3 is fixedly connected to the inner wall of the wire cylinder 2.

[0042] Specifically, in order to ensure the working stability of the conductor cylinder 2, two support plates 13 are fixedly installed on the front side of the support frame 1. Both support plates 13 are fixedly installed on the conductor cylinder 2 and are arranged in a parallel manner.

[0043] Anti-slip pads are fixedly installed on the side of each of the two brake plates 3 that are close to each other, in order to improve the resistance to the movement of the thread.

[0044] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0045] Working principle:

[0046] When the doubling machine is working normally, the electromagnet 34 is energized and generates magnetism, attracting the iron plate 35, which in turn drives the two brake plates 3 to move away from each other. At this time, the spring 333 is in a compressed state. The yarn is released from the pay-off roller 11, passes through the guide tube 2, and is finally collected by the take-up roller 12.

[0047] When the wire breaks inside the conductor drum 2, the control system detects the abnormality and immediately cuts off the power supply to the electromagnet 34. The electromagnet 34 loses its magnetism and the attraction to the iron plate 35 disappears. At this time, the spring 333 quickly resets and controls the connecting plate 32 to move closer to the conductor drum 2. Then, through the strip block 31, the brake plate 3 quickly stops the broken wire passing through the conductor drum 2, preventing it from continuing to participate in the twisting process.

[0048] Meanwhile, the guide plate 301 can prevent wires and debris from entering the two brake plates 3 on the side that are far apart from each other, ensuring the normal operation of the brake plates 3. In addition, the guide ring 201 can prevent abnormal friction between the wire and the end of the wire cylinder 2 when the wire enters and exits the wire cylinder 2, extending the service life of the wire and the wire cylinder 2. The support plate 13 provides stable support for the wire cylinder 2, ensuring the stability of the entire mechanism.

[0049] The foregoing has provided a detailed description of the wire breakage prevention mechanism for a doubling twister provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
