Description

Technical Field

[0001] This application belongs to the field of melt spinning technology, specifically relating to an automatic yarn feeding device and winding equipment. Background Technology

[0002] In the fields of chemical fiber, textile, and cable processing, winding equipment is the core equipment for winding and shaping yarn. It mainly uses the rotational motion of winding rollers to neatly wind continuously output yarn into finished rolls of uniform specifications. Among them, the initial yarn feeding process is the key starting process of the winding operation, which directly determines the continuity, stability, and quality of the subsequent winding operation and the finished product winding quality. During the production process, multiple yarns to be processed must be accurately guided to the corresponding yarn feeding and positioning positions on the equipment to complete the initial yarn feeding, positioning, and fixing before automated winding production can be started.

[0003] Currently, the raw yarn feeding operation mode of existing winding equipment is relatively traditional. For the synchronous feeding of multiple yarns, it generally relies on operators to manually pick up each yarn one by one, pull and align it, and fix it at the corresponding feeding station. However, the manual-assisted feeding mode is highly dependent on human experience. The process of synchronously aligning and pulling multiple yarns is cumbersome, and the consistency of human operation is poor, resulting in extremely low overall feeding efficiency and making it unsuitable for the needs of large-scale, high-speed winding production. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an automatic yarn feeding device and winding equipment, which aims to at least partially solve the technical problem of low efficiency in manual yarn feeding operations.

[0005] The technical solution of this invention is as follows: An automatic yarn feeding device includes: a frame; a sliding member slidably disposed on the frame; a yarn feeding comb rotatably connected to the sliding member and switchable between a first position and a second position; a fixed guide member disposed on the frame, the fixed guide member having a guide groove; and a posture guide member connected to the yarn feeding comb and slidably disposed within the guide groove. When the yarn feeding comb is in the first position, the yarn feeding comb and the yarn feeding member are arranged at an angle, and the yarn feeding comb and the yarn feeding member are spaced apart. When the yarn feeding comb is in the second position, the yarn feeding comb and the yarn feeding member are arranged parallel to each other, and the yarn feeding comb and the yarn feeding member are spaced apart. When the yarn feeding comb is in the third position, along the height direction of the frame, the projection of the yarn feeding comb on the frame at least partially overlaps the projection of the yarn feeding member on the frame.

[0006] In some embodiments, the automatic yarn feeding device further includes a drive assembly slidably connected to the slider.

[0007] In some embodiments, the slider has a sliding groove, and the drive assembly includes: a driver disposed on the frame; a crank connected to the driver; and a connector connected to the end of the crank away from the driver and slidably disposed in the sliding groove.

[0008] In some embodiments, when the upper comb is in the third position, the drive assembly is located below the upper comb.

[0009] In some embodiments, the slider includes: a first sliding portion; and a second sliding portion, which is connected at an angle to the first sliding portion and is rotatably connected to the upper comb.

[0010] In some embodiments, the brush includes: a brush feeding portion; a connecting portion connected to the brush feeding portion, the connecting portion being rotatably connected to the sliding member; wherein the attitude guide is connected to the connecting portion.

[0011] In some embodiments, the brush further includes a rotating part connected to the connecting part and rotatably connected to the sliding member.

[0012] In some embodiments, the guide groove includes: a guide section; and a push section connected at an angle to the guide section; wherein, when the upper comb is in the first position, the attitude guide is located in the guide section; and when the upper comb is in the second and third positions, the attitude guide is located in the push section.

[0013] In some implementations, the guide segment is arc-shaped and the push segment is straight.

[0014] Based on the same inventive concept, this application also provides a winding device, including the aforementioned automatic yarn feeding device.

[0015] The beneficial effects of the present invention include at least the following: Because the sliding component is slidably mounted on the frame, the upper comb is rotatably connected to the sliding component and can switch between a first position, a second position, and a third position. A fixed guide component is mounted on the frame and has a guide groove. A posture guide component is connected to the upper comb and slidably mounted within the guide groove. When the upper comb is in the first position, it is angled relative to the upper wire-moving component, and the upper comb and the upper wire-moving component are spaced apart. Therefore, the upper comb can be positioned to the side of the upper wire-moving component. When the operator guides the wire to the upper comb with a suction gun for wire splicing and splitting, the high-temperature area near the upper wire-moving component can be avoided, ensuring operator safety. Simultaneously, operating space is reserved for the operator, improving the reliability of the wire entering the gap between the comb teeth and reducing the risk of wire leakage, wire bundling, and inadequate wire feeding. When wire feeding is required, the sliding component slides on the frame, and the posture guide component moves within the guide groove to align with the upper comb. The comb guides the movement of the upper wire guide, allowing it to rotate until it reaches the second position. The upper wire guide is parallel to the upper wire moving component and spaced apart from it. The sliding component continues to move, and under its influence, the attitude guide moves within the guide groove to guide the movement of the upper wire guide, causing it to move towards the upper wire moving component until it switches from the second position to the third position. When the upper wire guide is in the third position, along the height direction of the frame, the projection of the upper wire guide on the frame at least partially overlaps with the projection of the upper wire moving component on the frame. Therefore, the upper wire guide can feed the wire into the upper wire moving component to complete the wire feeding operation. This enables simultaneous alignment of multiple wires, automatic wire feeding, and improved efficiency. It can adapt to the needs of large-scale, high-speed winding production. Moreover, it makes the wire feeding trajectory easy to standardize and control, avoiding problems such as uneven wire tension and alignment misalignment, thus ensuring wire feeding accuracy.

For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0023] Specific technical solutions will now be described in detail with reference to the accompanying drawings, which are not necessarily drawn to scale. Similar or identical reference numerals may be used to designate the same or similar parts in different figures. The use of similar or identical reference numerals in different figures does not mean that all figures including similar or identical reference numerals constitute a single or the same embodiment. The accompanying drawings illustrate the various embodiments discussed in this application in a generalized, illustrative, and not restrictive manner.

[0024] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The automatic yarn feeding device according to this application embodiment includes: a frame 10, a sliding member 20, a yarn feeding comb 30, a fixed guide member 40, and a posture guide member 50. The sliding member 20 is slidably disposed on the frame 10. The yarn feeding comb 30 is rotatably connected to the sliding member 20 and can switch between a first position, a second position, and a third position. The fixed guide member 40 is disposed on the frame 10 and has a guide groove 41. The posture guide member 50 is connected to the yarn feeding comb 30 and is slidably disposed within the guide groove 41. Specifically, when the yarn feeding comb 30 is in the first position, the yarn feeding comb 30 and the yarn feeding component 60 are arranged at an angle, and the yarn feeding comb 30 and the yarn feeding component 60 are spaced apart. When the yarn feeding comb 30 is in the second position, the yarn feeding comb 30 and the yarn feeding component 60 are arranged parallel to each other. When the upper comb 30 is in the third position, along the height direction of the frame 10, the projection of the upper comb 30 on the frame 10 at least partially overlaps with the projection of the upper wire moving component 60 on the frame 10. For example, the attitude guide 50 may be an attitude guide pin.

[0025] Since the sliding member 20 is slidably mounted on the frame 10, the upper comb 30 is rotatably connected to the sliding member 20 and can switch between a first position, a second position, and a third position. The fixed guide member 40 is mounted on the frame 10 and has a guide groove 41. The posture guide member 50 is connected to the upper comb 30 and is slidably mounted in the guide groove 41. When the upper comb 30 is in the first position, the upper comb 30 and the upper wire moving member 60 are angled together, and the upper comb 30 and the upper wire moving member 60 are spaced apart. Therefore, the upper comb can be positioned so that... Located on the side of the upper wire-moving component 60, component 30 avoids the high-temperature area near the upper wire-moving component 60 when the operator guides the wire to the upper wire-moving comb 30 for wire splicing and splitting, ensuring operator safety. It also provides operating space for the operator, improving the reliability of the wire entering the gap between the comb teeth of the upper wire-moving comb 30 and reducing the risk of wire leakage, wire bundling, and inadequate wire feeding. When wire feeding is required, the sliding component 20 slides on the frame 10, and the attitude guide component 50 moves within the guide groove 41 to... The movement of the upper comb 30 is guided, allowing it to rotate until it reaches the second position. The upper comb 30 is parallel to the upper wire-shifting component 60, and they are spaced apart. The sliding member 20 continues to move, and under its influence, the attitude guide 50 moves within the guide groove 41 to guide the movement of the upper comb 30, causing it to move towards the upper wire-shifting component 60 until it switches from the second position to the third position. This is because the upper comb 30 is located in... In the third position, along the height direction of the frame 10, the projection of the upper wire comb 30 on the frame 10 and the projection of the upper wire moving component 60 on the frame 10 at least partially overlap. Therefore, the upper wire comb 30 can feed the wire into the upper wire moving component 60 to complete the wire feeding operation. This enables the synchronous alignment of multiple wires, automatic wire feeding, and improved efficiency. It can adapt to the needs of large-scale and high-speed winding production. Moreover, it makes the wire feeding trajectory easy to standardize and control, avoiding problems such as uneven wire tension and alignment deviation, and ensuring wire feeding accuracy.

[0026] In some embodiments, after the upper comb 30 has fed all the yarn into the upper yarn-moving component 60, the slider 20 actuates. Driven by the slider 20, the attitude guide 50 actuates within the guide groove 41 to guide the movement of the upper comb 30. The upper comb 30 moves away from the upper yarn-moving component 60, allowing it to switch from a third position to a second position. The upper comb 30 and the upper yarn-moving component 60 are spaced apart. The slider 20 continues to slide on the frame 10, and the attitude guide 50 actuates within the guide groove 41 to guide the movement of the upper comb 30, enabling it to rotate until it reaches the first position, thus preparing it for the next yarn feeding cycle.

[0027] In some embodiments, when the upper comb 30 is in the first position, the included angle between the upper comb 30 and the upper wire moving component 60 can be set to 45° to 135°. In this embodiment, the included angle between the upper comb 30 and the upper wire moving component 60 is 90°, that is, the upper comb 30 and the upper wire moving component 60 are set perpendicularly, which is only for illustrative purposes and should not be construed as a limitation of this application.

[0028] Combination Figure 4 , Figure 5 and Figure 6 In some embodiments, in order to enable the slider 20 to move on the frame 10, the automatic yarn feeding device further includes a drive assembly 70. The drive assembly 70 is slidably connected to the slider 20, and drives the slider 20 to move on the frame 10.

[0029] In some embodiments, to enable the drive assembly 70 to drive the slider 20 to move on the frame 10, the slider 20 is provided with a sliding groove 21. The drive assembly 70 includes a driver 71, a crank 72, and a connector 73. The driver 71 is disposed on the frame 10. The crank 72 is connected to the driver 71. The connector 73 is connected to the end of the crank 72 away from the driver 71 and is slidably disposed in the sliding groove 21. For example, the driver can be a motor, the connector 73 can be a pin, and the driver 71 is disposed on the frame 10.

[0030] The actuator 71 drives the connecting member 73 to move within the sliding groove 21 via the crank 72, thereby causing the sliding member 20 to move on the frame 10. During the movement of the sliding member 20 on the frame 10, the attitude guide 50 moves within the guide groove 41 to guide the movement of the brush 30, enabling the brush 30 to rotate or move. Moreover, by using only one actuator 71, both the rotation and movement of the brush 30 can be achieved, thus reducing costs.

[0031] Combination Figure 6 In some embodiments, when the upper comb 30 is in the third position, the drive component 70 is located below the upper comb 30 to avoid the drive component 70 interfering with the action of the upper comb 30 and to ensure that the upper comb 30 can switch smoothly between the first position, the second position and the third position.

[0032] Combination Figure 4 , Figure 5 and Figure 6In some embodiments, in order for the slider 20 to drive the upper comb 30 to move, the slider 20 includes a first sliding portion 22 and a second sliding portion 23. The second sliding portion 23 is connected to the first sliding portion 22 at an angle and is rotatably connected to the upper comb 30. The first sliding portion 22 and the second sliding portion 23 slide on the frame 10, and the second sliding portion 23 drives the upper comb 30 to move. For example, along the length direction of the first sliding portion 22, the first sliding portion 22 has a sliding groove 21.

[0033] In some embodiments, the included angle between the first sliding part 22 and the second sliding part 23 can be set to 45° to 135°. In this embodiment, the included angle between the first sliding part 22 and the second sliding part 23 is 90°, that is, the first sliding part 22 and the second sliding part 23 are set perpendicularly, which is only used as an example and should not be construed as a limitation of this application.

[0034] Combination Figure 4 , Figure 5 and Figure 6 In some embodiments, to ensure smooth wire feeding, the wire feeding comb 30 includes a wire feeding section 31 and a connecting section 32. The connecting section 32 is connected to the wire feeding section 31 and is rotatably connected to the sliding member 20. The attitude guide member 50 is connected to the connecting section 32.

[0035] The wire feeding operation is carried out through the wire feeding part 31, and the wire can be rotated or moved through the connecting part 32 to avoid interfering with the wire feeding operation and ensure the smooth progress of the wire feeding operation.

[0036] Combination Figure 4 , Figure 5 and Figure 6 In some embodiments, to enable the connecting portion 32 to be rotatably connected to the slider 20, the upper comb 30 further includes a rotating portion 33. The rotating portion 33 is connected to the connecting portion 32 and rotatably connected to the slider 20, so that the connecting portion 32 can rotate on the slider 20. For example, the rotating portion 33 can be a rotating shaft.

[0037] Combination Figure 4 , Figure 5 and Figure 6In some embodiments, to enable the upper comb 30 to rotate and move, the guide groove 41 includes a guide section 411 and a push section 412. The push section 412 is connected to the guide section 411 at an angle. When the upper comb 30 is in a first position, the attitude guide 50 is located in the guide section 411, and the guide section 411 guides the attitude guide 50, allowing the upper comb 30 to rotate. When the upper comb 30 is in a second and third position, the attitude guide 50 is located in the push section 412, and the push section 412 guides the attitude guide 50, allowing the upper comb 30 to move. For example, the included angle between the push section 412 and the guide section 411 can be an acute angle.

[0038] Combination Figure 4 , Figure 5 and Figure 6 In some embodiments, the guide section 411 is arc-shaped to ensure that the upper comb 30 can rotate when switching between a first position and a second position. Exemplarily, the opening of the guide section 411 faces away from the upper wire moving component 60.

[0039] Combination Figure 4 , Figure 5 and Figure 6 In some embodiments, the push section 412 is linear, ensuring that the upper comb 30 can move when switching between the second and third positions. Exemplarily, the push section 412 extends in the direction of the upward-moving yarn member 60.
