Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a wear-resistant yarn bobbin fixing frame based on magnetic levitation. Background Technology

[0002] A textile bobbin is a cylindrical device used to wind yarn. In the textile process, textile bobbins are used in equipment such as looms and knitting machines to support the raw yarn. During the use of the bobbin, a fixing frame is required to fix the bobbin and ensure that the textile machinery can operate normally.

[0003] A yarn bobbin fixing frame typically consists of a fixing rod that supports the yarn bobbin and corresponding fixing devices. Currently, the fixing process of the yarn bobbin is adjustable, and the fixing process is achieved by rotating the threaded rod. However, when it is necessary to install or replace the yarn bobbin, the yarn bobbin needs to be tightened to the fixing frame by screwing. If a large number of yarn bobbins need to be installed, the operation of tightening the threads one by one will consume a lot of time and effort, reducing production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a wear-resistant yarn bobbin fixing bracket based on magnetic levitation, so as to solve the problem of low efficiency in the process of fixing yarn bobbins using threaded rods as mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant yarn tube fixing frame based on magnetic levitation, comprising a support tube, a cylindrical groove provided on the upper surface of the support tube, four support blocks arranged in a ring on the outer surface of the support tube, the upper cross section of the support blocks being an arc-shaped structure, a telescopic rod provided on one side surface of the support block, the other end of the telescopic rod being fixedly installed on the outer surface of the support tube, a spring provided on the outer surface of the telescopic rod, one end of the spring being connected to the surface of the support tube, the other end of the spring being connected to the surface of the support block, and a levitation support structure provided on the lower surface of the support tube. The levitation support structure can provide support and guidance for the rotation of the support tube, reducing wear during the rotation of the support tube.

[0006] Preferably, the suspension support structure includes a base, which is a cylindrical structure with an open upper surface. A guide cylinder is fixedly installed on the bottom surface of the base. The guide cylinder has an open upper surface, and its inner surface wraps around the lower end of the support cylinder. An upper magnetic ring is fixedly connected to the lower surface of the support cylinder, and a lower magnetic ring is aligned below the upper magnetic ring. The lower magnetic ring is fixedly connected to the bottom surface of the guide cylinder, and the magnetic poles of the upper and lower magnetic rings repel each other. A sliding groove is provided on the outer surface of the support cylinder, and a slider is slidably connected in the sliding groove on the surface of the support cylinder. The slider is fixedly connected to the inner wall of the guide cylinder.

[0007] By adopting the above technical solution, the suspended support structure can provide support from below the support cylinder and reduce wear generated during the rotation of the support cylinder.

[0008] Preferably, the support cylinder is provided with an airbag support structure inside, which can realize the horizontal reinforcement process of the support block.

[0009] By adopting the above technical solution, the horizontal reinforcement process of the support block can be achieved by using the airbag support structure.

[0010] Preferably, the airbag support structure includes a first airbag, which is disposed in a groove on the upper surface of the support cylinder. The surface of the first airbag is made of a compressible flexible material. A second airbag is disposed on the outer surface of the support cylinder. The second airbag has a circular structure and its surface is fixedly connected to the surface of the support cylinder. Multiple second airbags are arranged parallel to each other vertically and are connected to each other by pipes. The second airbag is located between the support cylinder and the support block. The lowest second airbag is connected to the first airbag by a pipe that passes through the surface of the support cylinder.

[0011] Using the above technical solution, by using the pusher to squeeze the first airbag, the air inside the first airbag can be squeezed into the second airbag on the outside, thus fixing the support block.

[0012] Preferably, a push plate is provided above the No. 1 airbag, the push plate is slidably connected to the inner wall of the support cylinder, a limit block is fixedly installed on the inner wall of the support cylinder, the limit block is a circular ring structure, and the inner diameter of the limit block is smaller than the diameter of the push plate, the inner surface of the limit block is provided with threads, a push rod is provided through the inner surface of the limit block, the main body of the push rod is a smooth round rod, the upper section of the outer surface of the push rod is provided with external threads and is threaded to the inner surface of the limit block, and the lower end of the push rod is in contact with the upper surface of the push plate.

[0013] Using the above technical solution, the movement of the push block can be achieved by using a push rod.

[0014] Preferably, the lower surface of the support cylinder is provided with a triggering structure, which can fix the yarn cylinder in the vertical direction.

[0015] By adopting the above technical solution, the vertical direction of the yarn bobbin can be fixed by using the trigger structure.

[0016] Preferably, the triggering structure includes an electromagnet, which is a ring structure. The electromagnet is sleeved on the outer surface of the guide cylinder and is fixedly connected to the bottom surface of the base. The electromagnet is connected to an external power source through a wire. A magnetic block is provided above the electromagnet. The magnetic block is ring-shaped. The lower surface of the magnetic block is connected to the bottom surface of the base through another set of telescopic rods. The magnetic poles of the electromagnet and the magnetic block repel each other.

[0017] By adopting the above technical solution, the vertical driving process of the yarn bobbin can be realized by utilizing the repulsive force between the electromagnet and the magnetic block.

[0018] Preferably, the upper surface of the support block is provided with a limiting structure, which, together with the triggering structure, can fix the yarn bobbin in the vertical direction.

[0019] Using the above technical solution, the upper end of the yarn tube can be fixed by the limiting structure.

[0020] Preferably, the limiting structure includes a positioning plate, which is slidably connected to the upper surface of the support block. The positioning plate is driven by a positioning block, and the main body of the positioning block is a cylindrical structure with an open lower surface. The outer surface of the cylindrical part of the positioning block is provided with a sloping protrusion, and the protrusion on the outer surface of the positioning block is aligned with the side of the positioning plate near the support cylinder.

[0021] Using the above technical solution, the positioning plate can be used to limit and fix the yarn bobbin from above.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the wear-resistant yarn tube fixing frame based on magnetic levitation fixation:

[0023] 1. In this invention, a support cylinder and a support block are provided to support the yarn tube. The lower surface of the support cylinder is inserted into the guide cylinder inside the base and connected by a slider on the inner wall of the guide cylinder. A magnetic ring is fixedly installed on the lower surface of the support cylinder and repulses the lower magnetic ring inside the guide cylinder. This ensures that the support cylinder will not deviate under the guidance of the slider during the rotation driven by the yarn tube, and reduces wear between the lower surface of the support cylinder and the base.

[0024] Furthermore, a first airbag is installed inside the support cylinder, connected to a second airbag on the outer surface. The second airbag is located between the support cylinder and the support block. When the yarn bobbin is fitted onto the surface of the support block, a push rod drives the push block inside the support cylinder to move, compressing the air in the first airbag through a pipe into the outer second airbag, thereby clamping and fixing the yarn bobbin horizontally.

[0025] 2. In this invention, a locking plate is slidably set on the upper surface of the support block. When the push rod moves, the locking block on the outer surface of the push rod pushes the locking plate outward to slide, thereby blocking the top of the yarn tube. A movable magnetic block is set below the support tube, and a fixed electromagnet is set to repel it. When the electromagnet is energized, it will push the magnetic block upward. The moving magnetic block pushes the yarn tube upward, cooperating with the locking plate to fix the yarn tube in the vertical direction. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-9 The present invention provides a technical solution: a wear-resistant yarn tube fixing frame based on magnetic levitation, comprising a support cylinder 1, a support block 2, a telescopic rod 3, a spring 4, a base 5, a guide cylinder 6, an upper magnetic ring 7, a lower magnetic ring 8, a slider 9, a first airbag 10, a second airbag 11, a push plate 12, a push rod 13, a limiting block 14, an electromagnet 15, a magnetic block 16, a locking plate 17, and a locking block 18.

[0038] A cylindrical groove is provided on the upper surface of the support cylinder 1. Four support blocks 2 are arranged in a ring on the outer surface of the support cylinder 1. The upper cross section of the support block 2 is arc-shaped. A telescopic rod 3 is provided on one side surface of the support block 2. The other end of the telescopic rod 3 is fixedly installed on the outer surface of the support cylinder 1. A spring 4 is provided on the outer surface of the telescopic rod 3. One end of the spring 4 is connected to the surface of the support cylinder 1, and the other end of the spring 4 is connected to the surface of the support block 2. A floating support structure is provided on the lower surface of the support cylinder 1. The floating support structure can provide support and guidance for the rotation of the support cylinder 1 and reduce wear during the rotation of the support cylinder 1. The suspension support structure includes a base 5, which is a cylindrical structure with an open upper surface. A guide cylinder 6 is fixedly installed on the bottom surface of the base 5. The guide cylinder 6 has an open upper surface and its inner surface wraps around the lower end of the support cylinder 1. An upper magnetic ring 7 is fixedly connected to the lower surface of the support cylinder 1. A lower magnetic ring 8 is aligned below the upper magnetic ring 7 and is fixedly connected to the bottom surface of the guide cylinder 6. The magnetic poles of the upper magnetic ring 7 and the lower magnetic ring 8 repel each other. A groove is provided on the outer surface of the support cylinder 1. A slider 9 is slidably connected in the groove on the surface of the support cylinder 1 and is fixedly connected to the inner wall of the guide cylinder 6.

[0039] like Figure 1 , Figure 3 and Figure 4 As shown, when using this device, the lower end of the yarn bobbin is inserted into the outer surface of the support block 2, so that the inner surface of the yarn bobbin wraps around the support block 2. The yarn bobbin can be supported by the telescopic rod 3 and the spring 4, so that the yarn bobbin is sleeved on the outer surface of the support cylinder 1 and the support block 2. After the yarn bobbin is fixed to the support cylinder 1 and the support block 2, the support cylinder 1 and the support block 2 rotate synchronously during the rotation of the yarn bobbin. When the support cylinder 1 rotates, the sliding groove on the outer surface of the support cylinder 1 is guided by the slider 9 on the inner wall of the guide cylinder 6 to ensure that the rotation of the support cylinder 1 is not deviated. The upper magnetic ring 7 and the lower magnetic ring 8 set at the lower end of the support cylinder 1 repel each other to ensure that the lower end of the support cylinder 1 does not contact the bottom surface of the guide cylinder 6, thereby reducing the wear phenomenon generated by the support cylinder 1 during the rotation.

[0040] The support cylinder 1 has an internal airbag support structure that provides horizontal reinforcement to the support block 2. The airbag support structure includes a first airbag 10, which is positioned within a groove on the upper surface of the support cylinder 1. The surface of the first airbag 10 is made of a compressible, flexible material. A second airbag 11, a circular structure, is positioned on the outer surface of the support cylinder 1. The surface of the second airbag 11 is fixedly connected to the surface of the support cylinder 1. Multiple second airbags 11 are arranged parallel to each other vertically and are connected by pipes. The second airbags 11 are located between the support cylinder 1 and the support block 2, at the bottom. The second airbag 11 is provided with a pipe that passes through the surface of the support cylinder 1 and is connected to the first airbag 10. A push plate 12 is provided above the first airbag 10. The push plate 12 is slidably connected to the inner wall of the support cylinder 1. A limit block 14 is fixedly installed on the inner wall of the support cylinder 1. The limit block 14 is a ring structure and the inner diameter of the limit block 14 is smaller than the diameter of the push plate 12. The inner surface of the limit block 14 is provided with threads. A push rod 13 is provided through the inner surface of the limit block 14. The main body of the push rod 13 is a smooth round rod. The upper section of the outer surface of the push rod 13 is provided with external threads and is threaded to the inner surface of the limit block 14. The lower end of the push rod 13 is in contact with the upper surface of the push plate 12.

[0041] like Figure 1 , Figure 5 and Figure 6 As shown, during the horizontal fixing of the yarn bobbin, the yarn bobbin is located on the outer surface of the support block 2. The push rod 13 is pushed into the support cylinder 1 by hand. The push rod 13 pushes the push plate 12 downward, and the push plate 12 squeezes the first airbag 10 downward, causing the first airbag 10 to deform and compress. The air inside the first airbag 10 enters the second airbag 11 outside along the connected pipe, causing the second airbag 11 to inflate. The inflated second airbag 11 plays a clamping and fixing role between the support cylinder 1 and the support block 2, fixing the yarn bobbin horizontally. At the same time, the thread on the outer surface of the push rod 13 is connected to the thread on the inner surface of the limiting block 14, fixing the push rod 13 to the support cylinder 1.

[0042] A triggering structure is provided on the lower surface of the support cylinder 1. This triggering structure can fix the yarn bobbin vertically. The triggering structure includes an electromagnet 15, which is a circular ring structure. The electromagnet 15 is sleeved on the outer surface of the guide cylinder 6 and is fixedly connected to the bottom surface of the base 5. The electromagnet 15 is connected to an external power supply via a wire. A magnetic block 16, also circular, is provided above the electromagnet 15. The lower surface of the magnetic block 16 is connected to the bottom surface of the base 5 via another set of telescopic rods 3. The magnetic poles of iron 15 and magnetic block 16 repel each other. A limiting structure is set on the upper surface of support block 2. The limiting structure, together with the triggering structure, can fix the yarn tube in the vertical direction. The limiting structure includes a locking plate 17, which is slidably connected to the upper surface of support block 2. The locking plate 17 is driven by locking block 18. The main body of locking block 18 is a cylindrical structure with an open lower surface. The outer surface of the cylinder of locking block 18 is provided with a sloping protrusion. The protrusion on the outer surface of locking block 18 is aligned with the side of locking plate 17 near support cylinder 1.

[0043] like Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown, when the yarn bobbin is fitted onto the outer surface of the support block 2, the lower end of the yarn bobbin contacts the upper surface of the magnetic block 16. Under the action of gravity, the magnetic block 16 is pushed downward to contact the electromagnet 15. During the process of pushing the push rod 13 downward to fix it to the support cylinder 1, the locking block 18 on the outer surface of the push rod 13 moves downward synchronously. When the sloping protrusion on the surface of the locking block 18 contacts the locking plate 17, the continuing downward movement of the locking block 18 will push the locking plate 17 outward to slide on the upper surface of the support block 2, so that one side of the locking plate 17 extends out of the surface of the support block 2, limiting the upper end of the yarn bobbin. The power supply of the electromagnet 15 is turned on, and the electromagnet 15 is started. After being energized and generating magnetic force, the electromagnet 15 pushes the magnetic block 16 upward under the action of the magnetic force. The magnetic block 16 moves smoothly upward under the action of the telescopic rod 3. The upward-moving magnetic block 16 pushes the yarn bobbin on the outer surface of the support block 2 upward. After contacting the locking plate 17, the yarn bobbin is fixed in the vertical direction under the action of the locking plate 17 and the magnetic block 16. When disassembling the yarn bobbin, the power supply of the electromagnet 15 is disconnected, and the magnetic force of the electromagnet 15 is lost. The magnetic block 16 and the yarn bobbin move downward back to their original position under the action of gravity. The push rod 13 is rotated in the opposite direction to disassemble, so that the locking plate 17 loses the pushing force of the locking block 18. At this time, the yarn bobbin can be pulled out upward.

[0044] Working principle: The yarn bobbin is fitted onto the outer surface of the support cylinder 1 and support block 2. The push rod 13 is pushed downwards, causing the push plate 12 to move. The push plate 12 compresses the first airbag 10, allowing air from the first airbag 10 to enter the outer second airbag 11. The inflated second airbag 11 provides support between the support cylinder 1 and support block 2, ensuring the yarn bobbin is fixed horizontally. The push rod 13 is fixed to the limiting block 14 using threads. During this process, the push rod 13 drives the locking block 18 to move, pushing the locking plate 17 to slide. The sliding locking plate 17 restricts the upper end of the yarn bobbin. The electric motor is then activated. The power source of magnet 15, under the action of magnetic force, causes electromagnet 15 to push magnetic block 16 upward, and magnetic block 16 pushes the yarn bobbin upward to contact the locking plate 17, thereby realizing the process of fixing the yarn bobbin in the vertical direction. When the yarn bobbin rotates, the yarn bobbin drives the support cylinder 1 and support block 2 to rotate. The support cylinder 1 rotates under the guidance of the slider 9 on the inner wall of the guide cylinder 6, avoiding the rotational deviation of the support cylinder 1. The lower end of the support cylinder 1 uses the repulsive force between the upper magnetic ring 7 and the lower magnetic ring 8 to ensure that the lower end of the support cylinder 1 does not contact the bottom surface of the guide cylinder 6, reducing the wear phenomenon generated by the support cylinder 1 during rotation.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
