Description

Technical Field

[0001] This invention relates to the field of winding machine technology, and in particular to a winding device. Background Technology

[0002] A winding machine is a device that winds a thread-like object onto a specific workpiece. Commonly used winding machines wind enameled copper wire (for winding inductors in electronic and electrical products), enameled aluminum wire, and textile wire (for winding yarn bobbins and spools for textile machines), as well as heating wire, solder wire, electrical wire, and cables for electric heating appliances. Current hand-cranked winding machines cannot adjust the transmission ratio of the drive mechanism, and therefore cannot adjust the winding pitch. Summary of the Invention

[0003] The purpose of this invention is to provide a winding device that uses multiple sets of pulley assemblies to adjust the transmission ratio, thereby adjusting the winding spacing.

[0004] To achieve the above objectives, the present invention provides a winding device, comprising: frame; The drive mechanism is mounted on the frame; The winding mechanism includes a rotating shaft mounted on the frame, a winding disc disposed on the rotating shaft, and a first rotating disc, wherein the rotating shaft is connected to the driving mechanism for transmission. The adjustment mechanism includes a lead screw mounted on the frame, a slider connected to the lead screw, a wire guide block connected to the slider, and a second turntable disposed on the lead screw; Multiple sets of pulley assemblies are arranged around the rotating shaft and slidably connected to the first turntable in the radial direction, and are arranged around the lead screw and slidably connected to the second turntable in the radial direction; A belt, fitted onto multiple sets of said pulley assemblies; and The wire feeding mechanism is installed on the frame; The wire of the wire feeding mechanism passes through the wire feeding block and is wound around the winding reel.

[0005] In some embodiments, the first turntable includes a first disc body, a first grooved wheel, and a first disc cover mounted on the rotating shaft. The first disc cover covers the first disc body, and the first grooved wheel is rotatably disposed within the first disc body. The first disc cover has a plurality of first cover grooves, the first grooved wheel has a plurality of first wheel grooves, and the first disc body has a plurality of first disc grooves. Multiple sets of pulley assemblies are slidably connected to the first disc grooves by passing through the first cover grooves and the first wheel grooves respectively.

[0006] In some embodiments, the first cover groove and the first disc groove extend in a straight radial direction, the first wheel groove extends in a clockwise radial arc, and the first turntable includes a fixing knob that is threaded through an opening in the first disc body to the first grooved wheel and is used to define the position of the first grooved wheel.

[0007] In some embodiments, the drive mechanism includes a crank handle, a first gear and a second gear rotatably mounted on the frame, and a third gear mounted on the rotating shaft. The crank handle is mounted on the first gear, and the first gear, the second gear, and the third gear are sequentially meshed together.

[0008] In some embodiments, the drive mechanism further includes a housing, a first pawl, a first spring, a second pawl, a second spring, and a cam. One end of the first pawl, one end of the second pawl, and the cam are all rotatably connected to the housing. The cam is located between the first pawl and the second pawl. The first spring applies a spring force to the first pawl, causing the first pawl to move closer to the cam. The second spring applies a spring force to the second pawl, causing the second pawl to move closer to the cam. Rotating the cam causes the other end of the first pawl or the other end of the second pawl to engage with the first gear.

[0009] In some embodiments, the second turntable includes a second disc body, a second grooved wheel, and a second disc cover mounted on the lead screw. The second disc cover covers the second disc body, and the second grooved wheel is rotatably disposed in the second disc body. The second disc cover has a plurality of second cover grooves, the second grooved wheel has a plurality of second wheel grooves, and the second disc body has a plurality of second disc grooves. Multiple sets of pulley assemblies are slidably connected to the second disc grooves by passing through the second cover grooves and the second wheel grooves respectively.

[0010] In some embodiments, the second cover groove and the second disc groove extend in a straight radial direction, the second wheel groove extends in a counterclockwise arc in the radial direction, the second turntable includes a spring, one end of the spring passing through the opening of the second disc body and fixed to the outer edge of the second groove wheel, and the other end of the spring being fixed to the second disc body.

[0011] In some embodiments, the wire feeding mechanism includes a wire tensioner, a wire feeder, a connecting rod, and a third spring. The wire of the wire tensioner passes around the wire feeder and enters the wire guide block. One end of the connecting rod is rotatably connected to the frame, and the wire feeder is mounted on the other end of the connecting rod. The middle part of the connecting rod is connected to the frame through the third spring. The third spring applies a pulling force to the connecting rod, causing the wire feeder to move away from the wire guide block.

[0012] In some embodiments, the pulley assembly includes an axle, a pulley mounted on the axle, a first linear slider, a bearing, and a second linear slider, wherein the first linear slider, the bearing, and the second linear slider are slidably connected to the first turntable or the second turntable, and the belt is sleeved on the pulley.

[0013] In some embodiments, the lead screw is a reciprocating lead screw or a ball screw, and the winding reel is provided with a winding post.

[0014] This invention provides a winding device, which has the following advantages compared with the prior art: The drive mechanism is mounted on the frame. The winding mechanism includes a rotating shaft mounted on the frame, a winding reel on the rotating shaft, and a first turntable. The rotating shaft is connected to the drive mechanism. The adjustment mechanism includes a lead screw mounted on the frame, a slider connected to the lead screw, a wire guide block connected to the slider, and a second turntable on the lead screw. Multiple sets of pulley assemblies are arranged around the rotating shaft and slidably connected to the first turntable in the radial direction, and are arranged around the lead screw and slidably connected to the second turntable in the radial direction. A belt is sleeved on the multiple sets of pulley assemblies. The wire feeding mechanism is mounted on the frame. The wire of the wire feeding mechanism passes through the wire guide block and is wound on the winding reel.

[0015] Thus, by adjusting the diameter of the multiple pulley assemblies surrounding the rotating shaft to increase, and by adjusting the diameter of the multiple pulley assemblies surrounding the lead screw to decrease, the transmission ratio of the first turntable driving the second turntable is low, and the speed of the wire guide block moving with the slider is relatively fast, resulting in a relatively large winding spacing of the wire on the winding reel. Conversely, by adjusting the diameter of the multiple pulley assemblies surrounding the rotating shaft to decrease, and by adjusting the diameter of the multiple pulley assemblies surrounding the lead screw to increase, the transmission ratio of the first turntable driving the second turntable is high, and the speed of the wire guide block moving with the slider is relatively slow, resulting in a relatively small winding spacing of the wire on the winding reel. Ultimately, by adjusting the transmission ratio through the multiple pulley assemblies, the winding spacing can be adjusted. Attached Figure Description

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0025] It should be understood that in the description of this application, the terms "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. That is, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, unless otherwise stated, "a plurality of" means two or more.

[0026] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figures 1-7 As shown, the winding device of some embodiments of the present invention includes: a frame 1, a drive mechanism 2, a winding mechanism 3, an adjustment mechanism 4, a multi-pulley assembly 5, a belt 6, and a wire feeding mechanism 7.

[0028] The drive mechanism 2 is mounted on the frame 1. The winding mechanism 3 includes a rotating shaft 31 mounted on the frame 1, a winding disc 32 disposed on the rotating shaft 31, and a first turntable 33. The rotating shaft 31 is connected to the drive mechanism 2 for transmission. The adjusting mechanism 4 includes a lead screw 41 mounted on the frame 1, a slider 42 connected to the lead screw 41, a wire guide block 43 connected to the slider 42, and a second turntable 44 disposed on the lead screw 41. Multiple sets of pulley assemblies 5 are arranged around the rotating shaft 31 and slidably connected radially to the first turntable 33, and are arranged around the lead screw 41 and slidably connected radially to the second turntable 44. A belt 6 is sleeved on the multiple sets of pulley assemblies 5. The wire feeding mechanism 7 is mounted on the frame 1.

[0029] During winding, the wire from the wire feeding mechanism 7 passes through the wire guide block 43 and winds onto the winding reel 32. The drive mechanism 2 drives the rotating shaft 31 of the winding mechanism 3 to rotate, thereby achieving the rotation and winding of the winding reel 32. At the same time, the pulley assembly 5 on the first turntable 33 drives the pulley assembly 5 on the second turntable 44 to rotate around the lead screw 41 via the belt 6, causing the second turntable 44 to drive the lead screw 41 to rotate, which in turn causes the slider 42 to drive the wire guide block 43 to move laterally, so that the wire is wound onto the winding reel 32 at intervals.

[0030] Based on the above structural configuration, by adjusting the diameter of the multiple sets of pulley assemblies 5 surrounding the rotating shaft 31 to increase and the diameter of the multiple sets of pulley assemblies 5 surrounding the lead screw 41 to decrease, the transmission ratio of the first turntable 33 driving the second turntable 44 is low, and the wire guide block 43 moves relatively fast with the slider 42, resulting in a relatively large winding spacing of the wire on the winding reel 32. Conversely, by adjusting the diameter of the multiple sets of pulley assemblies 5 surrounding the rotating shaft 31 to decrease and the diameter of the multiple sets of pulley assemblies 5 surrounding the lead screw 41 to increase, the transmission ratio of the first turntable 33 driving the second turntable 44 is high, and the wire guide block 43 moves relatively slowly with the slider 42, resulting in a relatively small winding spacing of the wire on the winding reel 32. Ultimately, the winding spacing is adjusted by using the multiple sets of pulley assemblies 5 to adjust the transmission ratio.

[0031] like Figure 5 As shown, in some embodiments, the first turntable 33 includes a first disc body 331 mounted on a rotating shaft 31, a first grooved wheel 332, and a first disc cover 333. The first disc cover 333 covers the first disc body 331, and the first grooved wheel 332 is rotatably disposed within the first disc body 331. The first disc cover 333 has multiple first cover grooves 334, the first grooved wheel 332 has multiple first wheel grooves 335, and the first disc body 331 has multiple first disc grooves 336. Multiple sets of pulley assemblies 5 are slidably connected to the first disc grooves 336, passing through the first cover grooves 334 and the first wheel grooves 335 respectively. This facilitates adjustment of the radial position of the pulley assemblies 5 on the first turntable 33.

[0032] like Figure 5 As shown, in some embodiments, the first cover groove 334 and the first disc groove 336 extend radially in a straight line, and the first wheel groove 335 extends radially in a clockwise arc. The first turntable 33 includes a fixing knob 337, which passes through the opening thread of the first disc body 331 and is threaded to the first grooved wheel 332, and is used to limit the position of the first grooved wheel 332. That is, tightening the fixing knob 337 prevents the first grooved wheel 332 from rotating, and loosening the fixing knob 337 allows the first grooved wheel 332 to rotate. In this way, the rotation of the first grooved wheel 332 can cause multiple pulley assemblies 5 to move radially simultaneously. The shape of the first wheel groove 335 ensures smooth movement of the pulley assembly 5, and further facilitates the adjustment of the radial position of the pulley assembly 5 on the first turntable 33.

[0033] like Figures 1-3 As shown, in some embodiments, the drive mechanism 2 includes a crank 21, a first gear 22 and a second gear 23 rotatably mounted on the frame 1, and a third gear 24 mounted on the rotating shaft 31. The crank 21 is mounted on the first gear 22, and the first gear 22, the second gear 23, and the third gear 24 are sequentially meshed together. Specifically, the diameter of the first gear 22 is larger than that of the second gear 23 and the third gear 24 to ensure that it requires less effort to rotate by the crank 21.

[0034] like Figure 3 As shown, in some embodiments, the drive mechanism 2 further includes a housing 25, a first pawl 26, a first spring 27, a second pawl 28, a second spring 29, and a cam 20. One end of the first pawl 26, one end of the second pawl 28, and the cam 20 are rotatably connected to the housing 25. The cam 20 is located between the first pawl 26 and the second pawl 28. The first spring 27 applies a spring force to the first pawl 26, causing it to move closer to the cam 20. The second spring 29 applies a spring force to the second pawl 28, causing it to move closer to the cam 20. Rotating the cam 20 causes the other end of either the first pawl 26 or the second pawl 28 to engage with the first gear 22. Thus, when the first pawl 26 is engaged with the first gear 22, the first gear 22 can only rotate clockwise; when the second pawl 28 is engaged with the first gear 22, the first gear 22 can only rotate counterclockwise. When the crank handle 21 is released, only unidirectional rotation is achieved, providing a non-return function.

[0035] like Figure 6 As shown, in some embodiments, the second turntable 44 includes a second disc body 441 mounted on the lead screw 41, a second grooved wheel 442, and a second disc cover 443. The second disc cover 443 covers the second disc body 441, and the second grooved wheel 442 is rotatably disposed within the second disc body 441. The second disc cover 443 has multiple second cover grooves 444, the second grooved wheel 442 has multiple second wheel grooves 445, and the second disc body 441 has multiple second disc grooves. Multiple sets of pulley assemblies 5 are slidably connected to the second disc grooves by passing through the second cover grooves 444 and the second wheel grooves 445 respectively. This facilitates adjustment of the radial position of the pulley assemblies 5 on the second turntable 44.

[0036] like Figure 6 As shown, in some embodiments, the second cover groove 444 and the second disc groove extend radially in a straight line, and the second wheel groove 445 extends radially in a counterclockwise arc. The second turntable 44 includes a spring 446, one end of which passes through the opening of the second disc body 441 and is fixed to the outer edge of the second grooved wheel 442, while the other end of the spring 446 is fixed to the second disc body 441. Thus, when the second grooved wheel 442 rotates, multiple pulley assemblies 5 can move radially simultaneously. The shape of the second wheel groove 445 ensures smooth movement of the pulley assemblies 5 and further facilitates adjustment of the radial position of the pulley assemblies 5 on the first turntable 33. The shape and position of the second disc groove are referenced to the first disc groove 336.

[0037] It should be noted that, since the first groove 335 extends in a clockwise arc along the radial direction and the second groove 445 extends in a counterclockwise arc along the radial direction, when the belt 6 drives the five pulley assemblies 5 to expand outward along the second groove 445, the second grooved pulley 442 rotates clockwise and the spring 446 tightens; conversely, when the belt 6 drives the five pulley assemblies 5 to converge towards the lead screw 41 along the second groove 445, the second grooved pulley 442 rotates counterclockwise and the spring 446 is stretched. In this way, the second grooved pulley 442 is always in a taut state, and the belt 6 transmission is more stable.

[0038] like Figure 4 As shown, in some embodiments, the wire feeding mechanism 7 includes a wire tensioner 71, a wire feeder 72, a connecting rod 73, and a third spring 74. The wire from the wire tensioner 71 passes around the wire feeder 72 and enters the wire guide block 43. One end of the connecting rod 73 is rotatably connected to the frame 1, and the wire feeder 72 is mounted on the other end of the connecting rod 73. The middle part of the connecting rod 73 is connected to the frame 1 via the third spring 74. The third spring 74 applies tension to the connecting rod 73, causing the wire feeder 72 to move away from the wire guide block 43. Thus, during the winding process, the wire feeder 72 can tension the wire.

[0039] like Figure 7 As shown, in some embodiments, the pulley assembly 5 includes a shaft 51, a pulley 52 mounted on the shaft 51, a first linear slider 53, a bearing 54, and a second linear slider 55. The first linear slider 53, the bearing 54, and the second linear slider 55 are slidably connected to the first turntable 33 or the second turntable 44, and a belt is sleeved on the pulley. Specifically, the first linear slider 53 slides in the first cover groove 334 or the second cover groove 444, the bearing 54 slides in the first wheel groove 335 or the second wheel groove 445, and the second linear slider 55 slides in the first disc groove 336 or the second disc groove.

[0040] In some embodiments, the lead screw 41 is a reciprocating lead screw, which allows the slider 42 to reciprocate on the reciprocating lead screw when the crank 21 is rotated in one direction. Alternatively, the lead screw 41 can be a ball screw, with a winding post 321 provided on the winding reel 32. Rotating the crank 21 clockwise and counterclockwise causes the slider 42 to reciprocate on the ball screw, and the winding reel 32 also rotates clockwise and counterclockwise. The winding post 321 secures the wire, preventing it from slipping off the winding reel 32.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
