Description

Technical Field

[0001] This utility model relates to the field of spinning production technology, and in particular to a quick-disassembly magnetic spinning extension air duct. Background Technology

[0002] The ring-blowing cooling technology for melt-spun synthetic fiber filaments is designed for the cooling process of melt-spun synthetic fiber filaments (especially polyester microfiber filaments). It uses an independent external ring-blowing method to cool the filaments, achieving the effect of cooling and solidifying the filament bundle. The design of the spinning extension air duct increases the length of the air duct, allowing the air entering the ring-blowing air box to pass through the wire mesh tube more evenly, thereby ensuring the uniformity of the spinning cooling conditions. This design not only helps to improve the quality of the fiber but also increases production efficiency.

[0003] Currently, conventional extension ducts are typically fixed to the air box with screws, with gaskets connecting the duct and air box to prevent air leakage. However, the yarn entering the extension duct is susceptible to interference from draft winds. This method has several drawbacks: 1. Damaged or uneven gaskets can cause the extension duct to tilt, contacting the yarn and causing yarn abrasion. Additionally, the yarn is easily affected by draft winds when entering the extension duct, impacting the yarn path and fiber strength. 2. Existing extension ducts are mainly fixed to the spinning air box with three screws arranged in a triangular pattern. These screws are prone to loosening or bending, causing the extension duct to shift or even fall off, resulting in yarn abrasion and breakage. 3. The existing extension ducts are difficult to install and remove, requiring specialized yarn processing personnel to use a hand drill. During batches, it takes 15 minutes to install and remove the extension ducts for one unit (based on 24 yarns), and the screws and gaskets need to be stored separately, significantly increasing the workload of yarn processing personnel. Therefore, a new technical solution is urgently needed to address at least one of these technical problems. Summary of the Invention

[0004] In view of the above shortcomings, the purpose of this utility model is to provide a magnetically attached spinning extension air duct that can be quickly disassembled to ensure that there is no air leakage between the air box and the air guide tube, which would cause internal air mixing and reduce the impact on the filament bundle. Moreover, it does not require additional screws for fixing, which greatly shortens the time and difficulty of batch installation and disassembly.

[0005] To achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted by this utility model is as follows:

[0006] A quick-detachable magnetic spinning extension duct, characterized in that it comprises:

[0007] The bellows contains an array of several ring-blowing mesh cylinders. A magnetic plate is installed at the bottom of the bellows by screws. The magnetic plate has several ventilation holes, and each ventilation hole is connected to one of the ring-blowing mesh cylinders.

[0008] Several air guide tubes are provided, and each air guide tube is provided with a magnetic ring connected to a magnetic plate at its top. The magnetic plate is provided with positioning parts that are the same number as the number of air guide tubes and correspond one-to-one. The positioning parts are used for coaxial alignment of the air guide tubes and ventilation holes.

[0009] As a preferred technical solution, the positioning component includes a number of positioning rods arranged in a ring on the magnetic plate, and a number of positioning holes are provided on the air guide tube, with the positioning rods respectively inserted into the positioning holes.

[0010] As a preferred technical solution, the positioning rod is made of plastic, and the end of the positioning rod is provided with several arc-shaped petals distributed in a ring.

[0011] As a preferred technical solution, the end of the positioning rod is provided with an excess groove, which is used to divide the end of the positioning rod into several mounting ends, and several arc-shaped petal blocks are respectively arranged in several mounting ends.

[0012] As a preferred technical solution, the bottom end of the ring-blowing mesh cylinder is constructed with an extension cylinder, which movably passes through the ventilation hole and is inserted into the air guide cylinder.

[0013] As a preferred technical solution, a heat insulation plate is provided between the air box and the magnetic plate.

[0014] As a preferred technical solution, the air guide duct includes a connected inclined transition section and a straight section, and the magnetic ring is disposed at the top of the inclined transition section.

[0015] As a preferred technical solution, the inner wall of the straight section is provided with a number of spiral grooves distributed in an annular pattern.

[0016] Compared with traditional technical solutions, the beneficial effects of this utility model are:

[0017] 1) By using the magnetic attraction of the magnetic plate and the magnetic ring, the air guide tube is placed below the magnetic plate, and the positioning component makes the air guide tube and the ring blowing mesh tube coaxially positioned. The magnetic plate automatically attracts the magnetic ring to fix the air guide tube. The magnetic attraction can increase the sealing between the air guide tube and the air box, ensuring that there is no air leakage between the air box and the air guide tube, which would cause internal air mixing and reduce the impact on the wire bundle. Moreover, no additional screws are required for fixing, which greatly shortens the time and difficulty of batch installation and disassembly.

[0018] 2) An excess groove is opened at the end of the positioning rod and an arc-shaped petal is set. Taking advantage of the deformable properties of its material, the positioning rod and the positioning hole are connected and matched. This not only allows for coaxial positioning of the air duct, but also improves the stability of the air duct after it is fixed. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be further described with reference to the accompanying drawings.

[0028] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "top," "bottom," "left," "right," "front," "rear," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0029] Please refer to Figures 1-7An embodiment of this utility model provides a quick-disassembly magnetic spinning extension air duct, including an air box 1 and several air guide tubes 4. Several annular blowing mesh tubes 2 are arrayed and connected inside the air box 1. The upper and lower ends of the annular blowing mesh tubes 2 are respectively connected to the upper and lower sides of the air box 1. The spinneret is located above the air box 1. The spun yarn is movably passed through several annular blowing mesh tubes 2. An air inlet pipe is connected to one side of the air box 1. The airflow enters the air box 1 from the air inlet pipe and is then blown inward from the outside of the annular blowing mesh tubes 2, thereby cooling the spun yarn. A magnetic suction plate 3 is installed at the bottom of the air box 1 by screws. Several ventilation holes are opened on the magnetic suction plate 3 and each of the several ventilation holes is connected to one of the several annular blowing mesh tubes 2.

[0030] Each of the several air ducts 4 is topped with a magnetic ring 5 magnetically connected to a magnetic plate 3. The magnetic ring 5 can be made of iron. The magnetic attraction between the magnetic plate 3 and the magnetic ring 5 allows the air duct 4 to be mounted on the bottom of the magnetic plate 3. Preferably, the magnetic plate 3 uses an Sm-Co magnet, which has strong magnetic power. The air duct 4 is made of lightweight aluminum alloy. The magnetic attraction between the magnetic plate 3 and the magnetic ring 5 ensures a tight seal between the air duct 4 and the magnetic plate 3. The magnetic plate 3 has a number of corresponding positioning points equal to the number of air ducts 4. Part 6, the positioning part 6, is used for coaxial alignment between the air guide tube 4 and the ventilation hole. By setting the positioning part 6, the air guide tube 4 can be effectively coaxially connected with the ring blowing mesh tube 2 after installation, further ensuring the connection and sealing between the magnetic plate 3 and the magnetic ring 5. This ensures that there will be no air leakage between the air box 1 and the air guide tube 4, which would cause internal air mixing and reduce the impact on the filament bundle. The magnetic adsorption structure does not require additional screws for fixing, which greatly shortens the time and difficulty of batch installation and disassembly of the air guide tube 4, and greatly saves production costs.

[0031] By utilizing the magnetic attraction of the magnetic plate 3 and the magnetic ring 5, the air guide tube 4 is placed below the magnetic plate 3, and the positioning component 6 makes the air guide tube 4 and the ring blowing mesh tube 2 coaxially positioned. The magnetic plate 3 automatically attracts the magnetic ring 5 to fix the air guide tube 4. The magnetic attraction can increase the sealing between the air guide tube 4 and the air box 1, ensuring that there is no air leakage between the air box 1 and the air guide tube 4, which would cause internal air mixing and reduce the impact on the filament bundle. Moreover, no additional screws are required for fixing, which greatly shortens the time and difficulty of batch installation and disassembly.

[0032] like Figure 6As shown, the positioning component 6 includes several positioning rods 601 arranged in a ring on the magnetic suction plate 3. The air guide tube 4 has several positioning holes 602. The positioning rods 601 are respectively inserted into the positioning holes 602. Preferably, the number of positioning rods 601 in the same positioning component 6 is three, and the included angle between the three is 120 degrees. When installing the air guide tube 4, the air guide tube 4 is placed below the magnetic suction plate 3, and the three positioning rods 601 are respectively aligned with the three positioning holes 602. Then the air guide tube 4 is moved up, so that the positioning rods 601 are inserted into the positioning holes 602, so that the air guide tube 4 and the ring blowing net tube 2 are effectively coaxial after magnetic attraction.

[0033] like Figure 5 As shown, the positioning rod 601 is made of plastic, and the end of the positioning rod 601 is provided with several arc-shaped petals 7 arranged in a ring. Preferably, the arc-shaped petals 7 are also made of plastic. The circumference diameter of the circle enclosed by the several arc-shaped petals 7 is larger than the inner diameter of the positioning hole 602. When inserted, a certain force is applied, and the deformable properties of the plastic material are used to force the several arc-shaped petals 7 to move closer together. When the positioning rod 601 passes through the positioning hole 602, the several arc-shaped petals 7 are released, thereby expanding and resetting. The several arc-shaped petals 7 play a role in resisting and supporting the air guide tube 4, further improving the stability of the air guide tube 4 after it is fixed.

[0034] like Figure 5 As shown, the end of the positioning rod 601 is provided with an excess groove 8, which is used to divide the end of the positioning rod 601 into several mounting ends. Several arc-shaped petal blocks 7 are respectively set at several mounting ends. Preferably, the cross-sectional structure of the excess groove 8 is cross-shaped, and the number of arc-shaped petal blocks 7 is four. The excess groove 8 is used to increase the deformation of the positioning rod 601 and the arc-shaped petal blocks 7, so that the stability of the air guide duct 4 can be improved more effectively after the deformation is restored.

[0035] like Figure 7 As shown, the bottom end of the ring-blowing mesh cylinder 2 is constructed with an extension cylinder 11. The extension cylinder 11 movably passes through the ventilation hole and is inserted into the air guide duct 4. Preferably, the extension cylinder 11 is integrally constructed with the ring-blowing mesh cylinder 2. The extension cylinder 11 serves as an axial extension of the ring-blowing mesh cylinder 2. By inserting it into the air guide duct 4, it just covers and blocks the magnetic attraction seam of the magnetic plate 3 and the magnetic ring 5, further improving its sealing performance.

[0036] like Figure 7 As shown, a heat insulation plate 9 is provided between the air box 1 and the magnetic plate 3. Preferably, the heat insulation plate 9 is made of silicone. The heat insulation plate 9 has ventilation holes that are the same number as the ventilation holes and correspond one-to-one. The heat insulation plate 9 can provide heat insulation and protection for the magnetic plate 3, improve the magnetic plate 3's resistance to demagnetization, and ensure the stability of the air guide tube 4.

[0037] like Figure 4 As shown, the air guide duct 4 includes a connected inclined transition section 401 and a straight section 402. A magnetic ring 5 is disposed on the top of the inclined transition section 401. The air guide duct 4 is composed of the top inclined transition section 401 and the straight section 402. This design allows the cooling air to pass through the inclined transition section 401 of the air guide duct 4. As its diameter gradually decreases, the cooling air velocity increases, the resistance to the nascent fibers decreases, the spinning speed can be increased, and the fiber quality can be improved.

[0038] like Figure 4 As shown, the inner wall of the straight section 402 is provided with several spiral grooves 10 arranged in a ring. Through the spiral grooves 10, when the airflow flows along the inside of the straight section 402, the airflow will flow in a spiral, which is convenient for guiding the spinning.
