Description

Technical Field

[0001] This utility model relates to the field of yarn storage devices, and in particular to an anti-reverse mechanism for yarn storage devices. Background Technology

[0002] A yarn storage device is a component in textile equipment used to store yarn. It mainly includes a stator, a rotor, and a yarn storage cylinder. The yarn storage cylinder is coaxially connected to the rotor. The rotor drives the yarn storage cylinder to rotate, and the yarn is wound around the periphery of the yarn storage cylinder for storage.

[0003] In existing technologies, an anti-reverse rotation mechanism is installed between the yarn storage cylinder and the rotor to prevent the yarn from reversing, which could cause the yarn to become tangled and knotted. Besides conventional one-way bearings, Chinese invention patent CN118684071A discloses an anti-reverse rotation mechanism for a yarn storage device. This mechanism includes an outer ring assembly and an inner ring assembly. The outer ring assembly includes an inner gear ring and a turntable coaxially fixed to the rotor. The inner ring assembly includes an anti-reverse rotation wedge and a mounting base. The mounting base is fixed to the stator and has a limiting groove. The anti-reverse rotation wedge rotates with the limiting groove and fits against the surface of the turntable. When the rotor drives the yarn storage cylinder to rotate forward, the turntable drives the anti-reverse rotation wedge to rotate in the forward direction, creating a gap between the end of the anti-reverse rotation wedge away from the limiting groove and the inner gear ring, allowing the rotor to rotate normally. When the rotor rotates in reverse, the turntable drives the anti-reverse rotation wedge to rotate in the reverse direction, causing the anti-reverse rotation wedge to lock the inner gear ring, preventing the rotor from rotating normally.

[0004] In the aforementioned technologies, the turntable uses friction to drive an anti-reverse wedge attached to its surface to rotate forward or backward. However, the anti-reverse wedge has a slow response speed and exhibits a sense of resistance as the turntable rotates. Furthermore, there is a delay in the anti-reverse mechanism's switching between allowing forward rotation and preventing reverse rotation. Prolonged friction between the turntable and the anti-reverse wedge can easily wear down the turntable and reduce the friction between them, affecting the normal operation of the anti-reverse mechanism. Utility Model Content

[0005] The purpose of this invention is to provide an anti-reverse mechanism for a yarn storage device, which has the advantages of smoother switching between allowing forward rotation and preventing reverse rotation, and that the turntable and anti-reverse wedge are not easily worn.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] This utility model provides an anti-reverse rotation mechanism for a yarn storage device. The anti-reverse rotation mechanism includes an outer ring assembly for coaxially fixing to the rotor and an inner ring assembly for coaxially fixing to the stator. The outer ring assembly includes an inner gear ring and a turntable, with the inner gear ring coaxially protruding from the turntable. The inner ring assembly includes a mounting base and an anti-reverse rotation wedge, with the mounting base for coaxially fixing to the stator.

[0008] A magnetic suction plate is fixedly installed on the side of the turntable facing the anti-reverse wedge; a limiting groove is provided on the mounting base, the limiting groove has a first limiting surface and a second limiting surface arranged at an angle, and the anti-reverse wedge is limited between the first limiting surface and the second limiting surface; the first end of the anti-reverse wedge is rotatably disposed in the limiting groove, the second end of the anti-reverse wedge extends toward the internal gear ring, and the second end of the anti-reverse wedge is connected to a magnetic suction block that magnetically attracts the magnetic suction plate;

[0009] When the anti-reverse wedge abuts against the first limiting surface, the anti-reverse wedge disengages from the internal gear ring; when the anti-reverse wedge abuts against the second limiting surface, the anti-reverse wedge abuts against the teeth of the internal gear ring.

[0010] In this design, the outer ring assembly of the anti-reverse rotation mechanism rotates with the rotor, while the inner ring assembly is connected to the stator. When the rotor rotates forward, the turntable drives the magnetic suction plate to rotate forward, and the magnetic suction plate and magnetic suction block attract each other, thereby causing the anti-reverse rotation wedge to rotate forward relative to the mounting base. This causes the anti-reverse rotation wedge to abut against the first limiting surface. At this time, the anti-reverse rotation wedge disengages from the inner gear ring and does not obstruct the inner gear ring, allowing the rotor to rotate normally and smoothly. When the rotor rotates in reverse, the magnetic suction plate drives the magnetic suction block and the anti-reverse rotation wedge to rotate in the opposite direction relative to the mounting base, causing the anti-reverse rotation wedge to abut against the second limiting surface. At this time, the anti-reverse rotation wedge abuts against the teeth of the inner gear ring to obstruct the inner gear ring, thus preventing the rotor from continuing to rotate in reverse and achieving anti-reverse rotation of the yarn accumulator. The mutual attraction between the magnetic suction plate and the magnetic suction block allows the rotor to smoothly drive the anti-reverse rotation wedge, reducing the resistance felt when the anti-reverse rotation wedge rotates on the turntable. This makes the switching between allowing the rotor to rotate forward and preventing it from rotating in reverse more smooth.

[0011] Furthermore, the magnetic chuck is annular, the stator passes through the inner ring of the magnetic chuck, and the outer diameter of the magnetic chuck is greater than the distance from the magnetic block to the center of the stator.

[0012] In this design, the magnetic chuck is circular, which makes it more stable when rotating. Its inner ring allows the stator to pass through to avoid interference with the stator, and its outer diameter is larger than the distance from the magnetic block to the center of the stator, so that the magnetic chuck can always maintain mutual attraction with the magnetic block.

[0013] Furthermore, the magnetic plate is detachably connected to the turntable.

[0014] In this design, the magnetic plate is detachably connected to the turntable, so that when the magnetic plate wears out after prolonged use of the anti-reverse mechanism, the magnetic plate on the turntable can be replaced, thus extending the service life of the anti-reverse mechanism.

[0015] Furthermore, the turntable has a positioning groove, and the magnetic plate is fitted into the positioning groove.

[0016] In this solution, a positioning groove is provided on the turntable to facilitate the coaxial positioning and installation of the magnetic chuck on the turntable.

[0017] Furthermore, the second end of the anti-reverse wedge has a mounting hole, and the magnetic block is fitted into the mounting hole.

[0018] In this design, the anti-reverse wedge is provided with mounting holes, through which the magnetic block is installed, facilitating the positioning and installation of the magnetic block and making it easy to replace.

[0019] Furthermore, the mounting hole is a round hole, and the magnetic block is cylindrical.

[0020] In this design, the mounting hole is a round hole, and the magnetic block is a cylindrical shape that fits the mounting hole, facilitating the mating of the magnetic block and the mounting hole.

[0021] Furthermore, the magnetic block protrudes from the side of the anti-reverse wedge facing the magnetic plate, and there is a gap between the anti-reverse wedge and the magnetic plate.

[0022] In this design, the magnetic block protrudes from the side of the anti-reverse wedge facing the magnetic plate, and there is a gap between the anti-reverse wedge and the magnetic plate, so that the anti-reverse wedge and the magnetic plate do not contact each other, and only the magnetic block and the magnetic plate make magnetic contact, thereby reducing wear between the anti-reverse wedge and the magnetic plate and improving the service life of the anti-reverse mechanism.

[0023] Furthermore, the magnetic block is a magnet, and the magnetic plate is made of ferromagnetic material.

[0024] Furthermore, the teeth of the internal gear ring are arc-shaped, and the multiple consecutive teeth of the internal gear ring extend in a sinusoidal function shape, and the outer peripheral surface of the second end of the anti-reverse wedge is an arc surface.

[0025] Furthermore, the mounting base has a circular rotating groove that communicates with the limiting groove; the first end is connected to a circular rotating protrusion that is rotatably disposed in the rotating groove and confined within the rotating groove, and the diameter of the rotating protrusion is greater than the width of the limiting groove.

[0026] In summary, this utility model has the following beneficial effects:

[0027] In this invention, the outer ring assembly of the anti-reverse rotation mechanism rotates together with the rotor, while the inner ring assembly is connected to the stator, thus achieving anti-reverse rotation of the yarn storage device. The magnetic plate and magnetic block attract each other, allowing the rotor to smoothly drive the anti-reverse rotation wedge to rotate, reducing the resistance felt when the anti-reverse rotation wedge rotates on the turntable. This makes the switching between allowing the rotor to rotate forward and preventing it from reversing smoother, and the turntable no longer relies on friction to drive the anti-reverse rotation wedge, thereby reducing frictional loss between the anti-reverse rotation wedge and the turntable.

Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings.

[0035] This embodiment discloses an anti-reverse mechanism for a yarn storage device, referring to... Figure 1 The yarn storage device 1000 includes a motor 100, a yarn storage cylinder 200, and an anti-reverse rotation mechanism 300. The yarn storage cylinder 200 is a cylindrical component, and the motor 100 is disposed inside the yarn storage cylinder 200. The anti-reverse rotation mechanism 300 is disposed between the motor 100 and the yarn storage cylinder 200 to prevent the motor 100 from rotating in the opposite direction.

[0036] In this embodiment, the housing of the motor 100 is fixedly connected to the yarn storage cylinder 200, and the stator 110 is fixedly connected to other equipment. When the yarn storage device 1000 is working, the stator 110 is fixed as a stator 110, and the housing part of the motor 100 acts as a rotor 120 to drive the yarn storage cylinder 200 to rotate to wind and store the yarn.

[0037] Reference Figure 1 and Figure 2 The anti-reverse mechanism 300 includes an outer ring assembly 310 and an inner ring assembly 320. The outer ring assembly 310 is coaxially fixed to the rotor 120 and the yarn storage cylinder 200, and the inner ring assembly 320 is connected to the stator 110, and the outer ring assembly 310 can rotate relative to the inner ring assembly 320.

[0038] Reference Figure 2 and Figure 3 The outer ring assembly 310 includes an inner gear ring 311, a turntable 312, and a magnetic suction plate 313. The turntable 312 is coaxially arranged with the motor 100 and the yarn storage cylinder 200. Specifically, in this embodiment, the yarn storage cylinder 200 is sleeved on the turntable 312, and the turntable 312 is fixedly connected to the yarn storage cylinder 200 by screws. The turntable 312 has a clearance hole in its center to avoid obstructing the stator 110.

[0039] In this embodiment, the internal gear ring 311 is fixedly connected to the turntable 312, and the internal gear ring 311 protrudes from the outer side of the turntable 312 (i.e., the side of the turntable 312 away from the motor 100 housing). The magnetic suction plate 313 is fixedly disposed on the outer side of the turntable 312 for magnetically attracting the inner ring assembly 320. In this embodiment, the turntable 312 and the internal gear ring 311 are coaxially fixedly connected; specifically, the internal gear ring 311 and the turntable 312 are integrally formed.

[0040] Reference Figure 2 and Figure 3 The inner ring assembly 320 is disposed outside the turntable 312 and located inside the internal gear ring 311. The inner ring assembly 320 includes a mounting base 321, an anti-reverse wedge block 322, and a magnetic block 323. The mounting base 321 is coaxially fixed to the stator 110, the anti-reverse wedge block 322 is rotatably connected to the mounting base 321, and the magnetic block 323 is fixedly disposed on the anti-reverse wedge block 322 and magnetically attracted to the magnetic plate 313.

[0041] In this embodiment, the mounting base 321 has a central hole, allowing it to be fitted onto the stator 110. The mounting base 321 is fixed to the stator 110 using screws or pins.

[0042] A limiting groove 3211 is provided on the mounting base 321, and an anti-reverse wedge 322 is installed in the limiting groove 3211. The limiting groove 3211 has a first limiting surface 3212 and a second limiting surface 3213, which are set at an included angle. The anti-reverse wedge 322 can rotate forward within the limiting groove 3211 to abut against the first limiting surface 3212 or rotate in the opposite direction to abut against the second limiting surface 3213.

[0043] The anti-reverse wedge 322 includes a first end 3221 and a second end 3222. The first end 3221 is eccentrically connected to the mounting base 321 (i.e., the center of the first end 3221 does not overlap with the center of the mounting base 321). The first end 3221 of the anti-reverse wedge 322 is rotatably confined within the limiting groove 3211, and the second end 3222 of the anti-reverse wedge 322 extends toward the internal gear ring 311. A magnetic block 323 is fixedly connected to the second end 3222 of the anti-reverse wedge 322. When the anti-reverse wedge 322 abuts against the first limiting surface 3212, the anti-reverse wedge 322 disengages from the internal gear ring 311; when the anti-reverse wedge 322 abuts against the second limiting surface 3213, the second end 3222 of the anti-reverse wedge 322 abuts against the teeth of the internal gear ring 311.

[0044] The teeth of the internal gear ring 311 are arc-shaped, and multiple consecutive teeth of the internal gear ring 311 extend in a sinusoidal shape. The outer peripheral surface of the second end 3222 of the anti-reverse wedge block 322 is an arc surface to facilitate contact with the arc-shaped teeth of the internal gear ring 311, preventing the internal gear ring 311 from reversing, while avoiding stress concentration that could damage the second end 3222 or the internal gear ring 311. When the anti-reverse wedge block 322 contacts the second limiting surface 3213, the outer peripheral surface of the second end 3222 faces the trough of the sinusoidal function, causing the second end 3222 to be locked between two adjacent locking teeth, preventing the internal gear ring 311 from reversing.

[0045] In addition, in other embodiments, the internal gear ring 311 may also adopt other suitable tooth shapes, and the corresponding second end 3222 may also be other suitable shapes.

[0046] Therefore, when the rotor 120 rotates in the forward direction, the turntable 312 drives the magnetic suction plate 313 to rotate in the forward direction. The magnetic suction plate 313 and the magnetic suction block 323 are magnetically attracted, thereby driving the anti-reverse wedge block 322 to rotate in the forward direction relative to the mounting base 321. This causes the anti-reverse wedge block 322 to abut against the first limiting surface 3212. At this time, the anti-reverse wedge block 322 disengages from the inner gear ring 311, and the anti-reverse wedge block 322 will not block the inner gear ring 311, allowing the rotor 120 to rotate normally and smoothly. When the rotor 120 rotates in the reverse direction, the magnetic suction plate 313 drives the magnetic suction block 323 and the anti-reverse wedge block 322 to rotate in the reverse direction relative to the mounting base 321, causing the anti-reverse wedge block 322 to abut against the second limiting surface 3213. At this time, the anti-reverse wedge block 322 abuts against the teeth of the inner gear ring 311 to block the inner gear ring 311, thereby preventing the rotor 120 from continuing to reverse, thus achieving the anti-reverse function of the yarn storage device 1000.

[0047] In this embodiment, the magnetic plate 313 and the magnetic block 323 attract each other, allowing the turntable 312 to smoothly drive the anti-reverse rotation wedge 322 to rotate when the rotor 120 rotates. This reduces the resistance of the anti-reverse rotation wedge 322 when rotating on the turntable 312, making the anti-reverse rotation mechanism 300 switch more smoothly between allowing the rotor 120 to rotate forward and preventing the rotor 120 from rotating in reverse. At the same time, the turntable 312 drives the anti-reverse rotation wedge 322 to rotate through magnetic attraction, reducing wear between the turntable 312 and the anti-reverse rotation wedge 322 and extending the service life of the anti-reverse rotation mechanism 300.

[0048] Specifically, in this embodiment, a reference straight line is drawn through the center of the mounting base 321 and the center of the first end 3221. The angle between the first limiting surface 3212 and the reference straight line is greater than the angle between the second limiting surface 3213 and the reference straight line. Therefore, when the anti-reverse wedge 322 reverses, the anti-reverse wedge 322 rotates from the first limiting surface 3212 to the second limiting surface 3213. During this process, the second end 3222 of the anti-reverse wedge 322 gradually approaches the teeth of the internal gear ring 311 until it locks the internal gear ring 311, thereby realizing the anti-reverse function of the anti-reverse mechanism 300.

[0049] Reference Figure 3 In this embodiment, the magnetic chuck 313 is annular, resulting in a uniform mass distribution and greater stability during rotation. The inner ring of the magnetic chuck 313 allows the stator 110 to pass through, preventing interference. The outer diameter of the magnetic chuck 313 is larger than the distance from the magnetic block 323 to the center of the stator 110, ensuring that the magnetic chuck 313 maintains a constant attraction with the magnetic block 323. Therefore, when the rotor 120 rotates forward continuously, the magnetic chuck 313 consistently drives the anti-reverse wedge 322 to abut against the first limiting surface 3212, preventing the anti-reverse wedge 322 from easily disengaging from vibration and affecting the normal rotation of the rotor 120.

[0050] In this embodiment, the magnetic plate 313 is detachably connected to the turntable 312, so that when the magnetic plate 313 wears out after prolonged use of the anti-reverse mechanism 300, the magnetic plate 313 on the turntable 312 can be replaced, thus extending the service life of the anti-reverse mechanism 300. Specifically, the magnetic plate 313 can be fixed to the turntable 312 by means of screw connection or snap-fit. In other embodiments, the magnetic plate 313 can also be fixed to the turntable 312 by other means such as bonding or welding.

[0051] In some embodiments, the turntable 312 is provided with a positioning groove, and the magnetic suction plate 313 is fitted into the positioning groove. By providing a positioning groove on the turntable 312, the magnetic suction plate 313 can be coaxially positioned and installed on the turntable 312, facilitating the installation and replacement of the magnetic suction plate 313.

[0052] Reference Figure 3 and Figure 4 The second end 3222 of the anti-reverse wedge block 322 has a mounting hole 3223, which penetrates the second end 3222. The magnetic block 323 is fitted into the mounting hole 3223, which facilitates the positioning and installation of the magnetic block 323, thereby facilitating the installation and replacement of the magnetic block 323.

[0053] Preferably, the magnetic block 323 is detachably installed in the mounting hole 3223, so that the magnetic block 323 can be replaced when it wears out. In one embodiment, the magnetic block 323 is interference-fitted with the mounting hole 3223 to facilitate connection between the magnetic block 323 and the mounting hole 3223.

[0054] In this embodiment, the mounting hole 3223 is a circular hole, and the magnetic block 323 is cylindrical to fit the mounting hole 3223, thereby facilitating the positioning and engagement of the magnetic block 323 and the mounting hole 3223. Furthermore, in other embodiments, the magnetic block 323 and the mounting hole 3223 may also be other suitable shapes.

[0055] In this embodiment, the magnetic block 323 protrudes from the side of the anti-reverse wedge 322 facing the magnetic plate 313, and there is a gap between the anti-reverse wedge 322 and the magnetic plate 313. This prevents the anti-reverse wedge 322 from contacting the magnetic plate 313, while only the magnetic block 323 and the magnetic plate 313 are in magnetic contact. This reduces wear between the anti-reverse wedge 322 and the magnetic plate 313 and improves the service life of the anti-reverse mechanism 300.

[0056] In this embodiment, the magnetic block 323 is a magnet, and the magnetic plate 313 is made of a ferromagnetic metal (such as iron, cobalt, nickel, or other metals or alloys), so that the magnetic block 323 and the magnetic plate 313 are magnetically attracted to each other. In other embodiments, both the magnetic block 323 and the magnetic plate 313 may also be made of magnets.

[0057] Reference Figure 3 and Figure 4 The mounting base 321 has a circular rotating groove 3214, which connects to the limiting groove 3211. A circular rotating protrusion 3224 is connected to the first end 3221. The rotating protrusion 3224 is rotatably disposed within the rotating groove 3214. The engagement of the rotating protrusion 3224 with the rotating groove 3214 enables the anti-reverse wedge 322 to rotate with the mounting base 321. The diameter of the rotating protrusion 3224 is larger than the width of the limiting groove 3211, making it difficult for the rotating protrusion 3224 to detach from the rotating groove 3214.

[0058] In this embodiment, the opening of the rotating groove 3214 faces the turntable 312, and the opening diameter of the rotating groove 3214 is larger than the diameter of the rotating protrusion 3224. Therefore, during assembly, the rotating protrusion 3224 can be inserted into the rotating groove 3214 from the side of the rotating groove 3214 facing the turntable 312, and then the mounting base 321 can be installed directly above the turntable 312, thereby confining the rotating protrusion 3224 within the rotating groove 3214, preventing the rotating protrusion 3224 from coming out, and facilitating the installation of the rotating protrusion 3224.

[0059] The number of anti-reverse wedges 322 can be one, two, or more. In this embodiment, multiple anti-reverse wedges 322 are provided, and multiple limiting grooves 3211 are provided on the mounting base 321. Specifically, in this embodiment, three limiting grooves 3211 are evenly spaced around the mounting base 321, and an anti-reverse protrusion is installed in each limiting groove 3211.

[0060] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
