Description

Technical Field

[0001] This invention relates to the field of yarn cleaning technology, and more specifically, to a yarn residual cleaning mechanism and winding line. Background Technology

[0002] In the textile production process, the winding process involves rewinding the smaller-capacity bobbins produced in the spinning process into larger-capacity, better-formed bobbins that are easier to process in subsequent steps (such as warping and weaving). During the winding process, when the yarn on the bobbin is completely unwound or breaks, a layer of unshed yarn (i.e., "residual yarn") often remains on the surface of the bobbin. If not cleaned in time, these bobbins with residual yarn will be recycled into the production line, not only contaminating the next spindle and causing a decline in yarn quality, but also potentially entangled in machine parts, causing equipment failure and downtime.

[0003] Existing technologies already offer solutions to the problem of residual yarn; for example, patent document CN202511077702.4 discloses a device for cleaning residual yarn by replacing the yarn tube. However, this technology has significant shortcomings in application: First, the device has a complex structure, requires frequent tube taking and putting actions, and has high precision requirements for the positioning and conveying mechanism of the yarn tube, increasing the equipment manufacturing cost and failure rate; Second, this solution still relies on manual periodic replenishment of new empty tubes to the device and manual handling of the replaced residual yarn tubes, failing to achieve fully automated residual yarn removal, resulting in high labor intensity and low efficiency. Summary of the Invention

[0004] To address the above deficiencies, this invention provides a bobbin yarn residue cleaning mechanism and a winding line, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The bobbin yarn residual yarn cleaning mechanism and winding line include a slide rail, a moving table, and bobbins, with the bobbins inserted on the moving table. It also includes: The telescopic rod consists of a sliding block, a sleeve, and a main tension spring. The sliding block slides along the side wall of the sleeve. In the first stage of the telescopic rod's extension, the sleeve contacts the moving platform under the action of gravity, at which point the sleeve and the moving platform are fixed in position. In the second stage of the telescopic rod's extension, the sliding block moves relative to the sleeve and the yarn tube. The main tension spring is stretched under the force. A circular roller is installed on the side wall of the sliding block. When the telescopic rod extends in the second stage, the circular roller cuts through the sleeve surface to cut off the remaining yarn until the circular roller moves to the bottom of the yarn tube and the telescopic rod shortens and resets. The bellows and negative pressure system: when the negative pressure system is working, the bellows generates negative pressure, and the residual yarn moves along the airflow moving from bottom to top.

[0006] Furthermore, it also includes a main frame, a moving platform, and yarn tubes passing through the main frame one by one. A pair of telescopic rods are provided and installed on the upper end of the main frame. A corrugated pipe passes through the upper end of the main frame. The sleeve sidewall has an elongated hole. A sliding block is slidably connected to the elongated hole. A crossbar is installed at the telescopic end of the telescopic rod. A sliding block is installed at one end of the crossbar. An annular protrusion is provided at the upper end of the sleeve. The main tension spring is installed between the annular protrusion and the crossbar.

[0007] Furthermore, a rectangular through hole is opened on the sliding block, a sliding rod is installed in the rectangular through hole, a tension spring is installed between the sliding rod and the sliding block, and a circular hob is installed at one end of the sliding rod.

[0008] Furthermore, a connecting rod is installed on the inner wall of the sleeve, a limit tube is installed on the connecting rod, a centering tube is installed inside the limit tube, a cone is installed at the lower end of the centering tube, and the lower end of the cone abuts against the top of the yarn tube; a secondary tension spring is installed between the centering tube and the connecting rod.

[0009] Furthermore, a telescopic sleeve is installed between the outer wall of the sleeve and the crossbar. When the telescopic sleeve covers the long hole, the long hole remains relatively closed.

[0010] Furthermore, the circular roller can be replaced with a stripping assembly, which includes a vertical bracket fixedly mounted on one end of a sliding rod, rollers mounted on both ends of the vertical bracket, a rubber belt mounted on the rollers, and the sidewall of the rubber belt adhering to the yarn tube; each vertical bracket is equipped with a drive motor, and the output end of the drive motor is connected to the roller drive.

[0011] Furthermore, a visual inspection device is installed on the side wall of the main frame.

[0012] Furthermore, the sleeve has a cavity, and the corrugated pipe is connected to the sleeve. The elongated hole is the air inlet, and the corrugated pipe is the exhaust outlet. External gas enters through the elongated hole and exits through the corrugated pipe, carrying away the cut-off residual yarn in the process.

[0013] Furthermore, the bobbin yarn residual yarn cleaning mechanism is installed at the bobbin yarn conveying end of the winding line.

[0014] The beneficial effects of this invention are: through the phased extension and retraction of a single telescopic rod, combined with gravity and spring energy storage, a series of actions such as sleeve positioning, roller (or stripping assembly) feeding and cutting, and tool reset can be completed sequentially; the whole process does not require complex multi-power source coordinated control, the logic is clear, and the cost is low; it realizes the automation and periodic cleaning of residual yarn, and greatly reduces the need for manual intervention; The circular roller cutter rotates and slashes across the surface of the sleeve to cut residual yarn. Its cutting path is precisely guided by the sleeve and will not directly contact or damage the internal yarn tube. When the peeling component (rubber belt) solution is used, the residual yarn is peeled upward by friction. It also has the advantages of flexible cleaning and protection of the yarn tube surface, ensuring that the yarn tube can be used repeatedly without damage. The cleaning mechanism works in conjunction with the negative pressure system. While cutting or peeling off residual yarn, it forms a stable airflow from bottom to top through the constructed airflow channels (long hole air intake, corrugated pipe exhaust). The cut / peeled residual yarn can be immediately carried away by the airflow and collected centrally by the negative pressure system, avoiding secondary entanglement and ensuring the cleanliness of the cleaning site and subsequent yarn tubes.

[0016] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] This application provides a bobbin yarn residue cleaning mechanism and winding line; please refer to [reference needed]. Figures 1-5 The system includes a slide rail 1, a moving table 2, and a yarn tube 3, with the yarn tube 3 inserted into the moving table 2. It also includes: The telescopic rod 4, sliding block 5, sleeve 6, and main tension spring 7 are included. Sliding block 5 slides along the side wall of sleeve 6. In the first stage of telescopic rod 4, the sleeve 6 contacts the moving platform 2 under the action of gravity. At this time, the sleeve 6 and the moving platform 2 are fixed in position. In the second stage of telescopic rod 4, the sliding block 5 moves relative to the sleeve 6 and the yarn tube 3. The main tension spring 7 is stretched by force. A circular roller cutter 8 is installed on the side wall of the sliding block 5. When the telescopic rod 4 extends in the second stage, the circular roller cutter 8 cuts off the residual yarn by slicing across the surface of the sleeve 6 until the circular roller cutter 8 moves to the bottom of the tube yarn 3 and the telescopic rod 4 shortens and resets. The bellows 9 and the negative pressure system: when the negative pressure system is working, the bellows 9 generates negative pressure, and the residual yarn moves along the airflow moving from bottom to top.

[0018] In practical applications, the vision inspection instrument 71 can detect whether there is residual yarn wrapped around the surface of the sleeve 6. After confirming that there is residual yarn wrapped around, the telescopic rod 4 is controlled to extend to remove the yarn. Initial state: Telescopic rod 4 is in its shortest state, sleeve 6 is at its highest position, and main tension spring 7 is in the retracted state; sliding block 5 is at the top of sleeve 6; State 1: The telescopic rod 4 extends in the first stage, the sleeve 6 moves downward under the action of gravity, the main tension spring 7 is in the contracted state, until the lower end of the sleeve 6 abuts against the moving table 2, at which point the sleeve 6 covers the yarn tube 3; State 2: The telescopic rod 4 extends in the second stage. As the lower end of the sleeve 6 abuts against the moving table 2, the extension of the telescopic rod 4 causes the sliding block 5 and the circular roller 8 to move downwards, and the main tension spring 7 gradually stretches. The circular roller 8 is pressed against the yarn tube 3 until the circular roller 8 moves to the bottom of the yarn tube 3. During this process, the residual yarn on the surface of the sleeve 6 is cut off. State 3: Telescopic rod 4 shortens and resets; Repeating the above process allows for continuous cutting of residual yarn, improving cleaning quality. Through the operation of the bellows 9 and the negative pressure system, the residual yarn moves along the airflow moving from bottom to top, achieving the purpose of automatic cleaning.

[0019] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 It also includes a main frame 21, a moving platform 2 and a bobbin 3 passing through the main frame 21 one by one, a pair of telescopic rods 4 installed on the upper end of the main frame 21, a corrugated pipe 9 passing through the upper end of the main frame 21, a long hole 22 on the side wall of the sleeve 6, a sliding block 5 slidably connected to the long hole 22, a crossbar 23 installed at the telescopic end of the telescopic rod 4, a sliding block 5 installed at one end of the crossbar 23, an annular protrusion 24 on the upper end of the sleeve 6, and a main tension spring 7 installed between the annular protrusion 24 and the crossbar 23.

[0020] In practical applications, the main frame 21 spans the slide rail 1 and supports the telescopic rod 4. To ensure the stable sliding of the sliding block 5, an elongated hole 22 is provided on the side wall of the sleeve 6, and the sliding block 5 slides along the elongated hole 22. When the telescopic rod 4 is shortened and reset, the main tension spring 7 is at its shortest when the crossbar 23 rises to the same level as the yarn tube 3. When the telescopic rod 4 continues to shorten, it pulls up the sleeve 6 to facilitate the passage of the yarn tube 3. The annular protrusion 24 provides sufficient space for the main tension spring 7 to move.

[0021] Reference Figure 1 , Figure 2 , Figure 3and Figure 4 A rectangular through hole 31 is opened on the sliding block 5, and a sliding rod 32 is installed in the rectangular through hole 31. A tension spring 33 is installed between the sliding rod 32 and the sliding block 5. A circular hob 8 is installed at one end of the sliding rod 32.

[0022] In practical applications, setting the cross-section of the rectangular through hole 31 and the sliding rod 32 to a rectangle can prevent the sliding rod 32 from rotating. By setting the tension spring 33, the sliding rod 32 and the circular roller 8 have a tendency to move towards the yarn tube 3, and at the same time, it can adapt to yarn tubes 3 of different diameters.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A connecting rod 34 is installed on the inner wall of the sleeve 6. A limiting tube 35 is installed on the connecting rod 34. A centering tube 38 is provided inside the limiting tube 35. A cone 36 is installed at the lower end of the centering tube 38. The lower end of the cone 36 abuts against the top of the yarn tube 3. A secondary tension spring 37 is installed between the centering tube 38 and the connecting rod 34.

[0024] In practical applications, the connecting rod 34 supports the limiting tube 35 and facilitates the upward discharge of the cut yarn residue. To improve the stability of the yarn tube 3, a centering tube 38 is provided; after the telescopic rod 4 extends in the first stage, the lower end of the cone 36 abuts against the top of the yarn tube 3 to prevent the yarn tube 3 from swaying left and right. As the telescopic rod 4 continues to extend, the secondary tension spring 37 can gradually extend, keeping the cone 36 in a stable state.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A telescopic sleeve 51 is installed between the outer wall of the sleeve 6 and the crossbar 23. When the telescopic sleeve 51 covers the elongated hole 22, the elongated hole 22 remains relatively closed.

[0026] In practical applications, by setting the telescopic sleeve 51, when there is negative pressure inside the bellows 9, the outside air is allowed to flow into the sleeve 6 from the space below the telescopic sleeve 51, so that a stable airflow is formed inside the sleeve 6, which is conducive to the discharge of residual yarn. The airflow can only flow in from the part of the telescopic sleeve 51 that does not cover the elongated hole 22.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The circular roller 8 can be replaced by a stripping assembly. The stripping assembly includes a vertical bracket 61 fixedly installed at one end of the sliding rod 32. Rollers 62 are installed at both ends of the vertical bracket 61. A rubber belt 63 is installed on the roller 62. The side wall of the rubber belt 63 is attached to the yarn tube 3. Each vertical bracket 61 is equipped with a drive motor 64. The output end of the drive motor 64 is connected to the roller 62 for transmission.

[0028] In practical applications, when the drive motor 64 rotates, it can drive the rubber belt 63 to rotate quickly. When the rubber belt 63 rotates, it uses friction to clean the residual yarn. Since the yarn tube 3 is conical, when the residual yarn moves upward relative to the yarn tube 3, the residual yarn is in a relaxed state. With the blowing of the airflow, the residual yarn can be discharged with the airflow. While the rubber belt 63 is working, the telescopic rod 4 can be controlled to repeatedly extend and retract within a small range, indirectly causing the rubber belt 63 to move up and down at high frequency, which is beneficial for the detachment of residual yarn from the bobbin yarn 3.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A visual inspection instrument 71 is installed on the side wall of the main frame 21.

[0030] In practical applications, the visual inspection instrument 71 can detect whether residual yarn is wrapped around the surface of the sleeve 6.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The sleeve 6 has a cavity 81 inside, and the bellows 9 is connected to the sleeve 6. The elongated hole 22 is the air inlet, and the bellows 9 is the exhaust outlet. External gas enters through the elongated hole 22 and exits through the bellows 9, taking away the cut-off residual yarn in the process.

[0032] In practical applications, external gas enters through the elongated hole 22 and exits through the corrugated pipe 9, carrying away the cut-off residual yarn in the process. The airflow enters the cavity 81 and moves from bottom to top, forming a stable airflow, which is conducive to the removal of residual yarn. The tube yarn residual yarn cleaning mechanism is installed at the tube yarn 3 conveying end of the winding line.
