[0030] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.
[0031] like Figures 1 to 4 As shown, a winding device 10 includes a support base 100, a rotating assembly 200, and a material-fixing assembly 300. The rotating assembly 200 includes a rotating drive member 210, a drive shaft 220, and a driven shaft 230. Both the drive shaft 220 and the driven shaft 230 are rotatably mounted on the support base 100, and the drive shaft 220 and the driven shaft 230 are coaxially arranged with a gap between them. The rotating drive member 210 is mounted on the support base 100, and the output shaft of the rotating drive member 210 is connected to the drive shaft 220. The material-fixing assembly 300 includes a central shaft 310, an adjusting member 320, a plurality of first support arms 330, a plurality of second support arms 340, and a plurality of support plates 350. Both ends of the central shaft 310 are provided with slots 311. When the driven shaft 230 slides close to the driving shaft 220, the driven shaft 230 and the driving shaft 220 respectively engage with the slots 311 at both ends of the central shaft 310. One end of each first support arm 330 is rotatably mounted on the central shaft 310, and the other end of each first support arm 330 is slidably connected to each support plate 350. The adjusting member 320 is slidably mounted on the central shaft 310. One end of each second support arm 340 is rotatably mounted on the adjusting member 320, and the other end of each second support arm 340 is rotatably connected to each support plate 350. Each second support arm 340 is rotatably connected to each first support arm 330 in a one-to-one correspondence.
[0032] It should be noted that the drive shaft 220 and driven shaft 230 are respectively mounted on the support base 100 via bearings. In one embodiment, the support base 100 includes a base plate and two support blocks, which are respectively mounted on both ends of the base plate. The drive shaft 220 is rotatably mounted on one support block, and the driven shaft 230 is rotatably mounted on the other support block, thus creating a gap between the drive shaft 220 and the driven shaft 230. The drive shaft 220 and the driven shaft 230 are also coaxially mounted. A rotary drive 210 is mounted on the support base 100 and is used to drive the drive shaft 220 to rotate. For example, the rotary drive 210 includes a motor and a belt, wherein the belt is connected to the output shaft of the motor and the drive shaft 220 respectively, thus the motor drives the drive shaft 220 to rotate via the belt. Furthermore, slots 311 are provided at both ends of the central shaft 310, so that when the driving shaft 220 and the driven shaft 230 engage with the slots 311 at both ends of the central shaft 310, the central shaft 310 is fixed by the driving shaft 220 and the driven shaft 230, allowing the central shaft 310 to be driven by the driving shaft 220 to rotate simultaneously. Furthermore, each first support arm 330 is rotatably mounted on the central shaft 310 via a pivot pin, and each first support arm 330 is slidably connected to each support plate 350. The adjusting member 320 is adjustablely mounted on the central shaft 310, and each second support arm 340 is rotatably mounted on the outer wall of the adjusting member 320, and each second support arm 340 is rotatably connected to each support plate 350. Each second support arm 340 is rotatably connected to each first support arm 330 via a through pin. Thus, by changing the position of the adjusting member 320 on the central axis 310, the diameter formed by each support plate 350 can be adjusted. When each support plate 350 is away from the central axis 310, it can tighten the yarn bobbin. When each support plate 350 is close to the central axis 310, it can release the yarn bobbin, thereby allowing the yarn bobbin to be stably fixed on or removed from the fixing assembly 300. Therefore, compared to existing fixing structures, the winding device 10 of this application has a simple structure and can stably fix the yarn bobbin, effectively reducing manufacturing costs.
[0033] like Figures 2 to 4 As shown, in one embodiment, at least one locking block 221 is provided on one end of the drive shaft 220 near the central shaft 310. The locking groove 311 includes a central groove 3111 and a side groove 3112. The drive shaft 220 is inserted into the central groove 3111 so that the locking block 221 is accommodated in the side groove 3112.
[0034] Thus, by using the locking block 221 to clamp the side groove 3112, the central shaft 310 and the drive shaft 220 are reliably fixed. In one embodiment, three locking blocks 221 are provided, and correspondingly three side grooves 3112 are also provided, with the three locking blocks 221 being adapted to be inserted into the three side grooves 3112 respectively.
[0035] like Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment, the driven shaft 230 includes a shaft body 231 and a bushing 232. The shaft body 231 is rotatably mounted on the bushing 232, and the shaft body 231 passes through the support base 100. The bushing 232 is screwed to the support base 100 so that the shaft body 231 is engaged with the slot 311.
[0036] It should be noted that the shaft 231 is rotatably mounted to the bushing 232 via a bearing. The shaft 231 passes through the support base 100. For example, if a linear bearing is installed on the support base 100, the shaft 231 is passed through the linear bearing, and then the bushing 232 is screwed to the support base 100, allowing the shaft 231 to be rotatably mounted to the support base 100. When the bushing 232 is removed from the support base 100, the bushing 232 pulls the shaft 231 out of the support base 100, thereby separating both ends of the central shaft 310 from the driving shaft 220 and the driven shaft 230 respectively for removal. When the bushing 232 is screwed onto the support base 100, the bushing 232 pulls the shaft 231 closer to the driving shaft 220, so that the driven shaft 230 and the driving shaft 220 can jointly clamp the central shaft 310.
[0037] like Figure 4 As shown, in one embodiment, the driven shaft 230 further includes a locking cover 233 and two thrust ball bearings 234. A stepped ring 235 is provided on the outer wall of the shaft body 231, and a stepped groove 2321 is provided in the bushing 232. The two thrust ball bearings 234 are both sleeved on the shaft body 231, and the two thrust ball bearings 234 are respectively located on both sides of the stepped ring 235. The shaft body 231 and the two thrust ball bearings 234 are both inserted into the stepped groove 2321. The locking cover 233 is provided on the bushing 232 so that the locking cover 233 and the inner wall of the stepped groove 2321 respectively clamp the two thrust ball bearings 234.
[0038] It should be noted that the bushing 232 has a stepped groove 2321, into which the shaft 231 and two thrust ball bearings 234 are inserted, with the two thrust ball bearings 234 located on opposite sides of the stepped ring 235. A locking cover 233 is installed on the bushing 232, so that the locking cover 233 and the inner wall of the stepped groove 2321 together clamp the two thrust ball bearings 234, which in turn clamp the shaft 231, allowing the shaft 231 to rotate stably relative to the bushing 232. Thus, when the bushing 232 is screwed and fixed to the support base 100, the shaft 231 can rotate stably relative to the support base 100. When the bushing 232 is removed from the support base 100, the bushing 232 moves the shaft 231 away from the drive shaft 220.
[0039] like Figure 3 and Figure 4 As shown, in one embodiment, the adjusting member 320 includes a slide 321 and a screw ring 322. The slide 321 is sleeved on the outer wall of the central shaft 310, and the screw ring 322 is screwed to the central shaft. The screw ring 322 is used to drive the slide 321 to slide back and forth along the axial direction of the central shaft 310. Each second support arm 340 is circumferentially rotatably arranged on the outer wall of the slide 321.
[0040] It should be noted that, in this way, when the threaded ring 322 rotates relative to the central shaft 310 under torque, the threaded ring 322 can drive the slide block 321 to slide along the axial direction of the central shaft 310. This causes each second support arm 340 to rotate relative to the first support arm 330, ultimately causing the support plates 350 to move away from or away from the central shaft 310.
[0041] like Figure 4 As shown, in one embodiment, a groove 312 is provided on the outer side wall of the central shaft 310 along the axial direction, and an inner protrusion 3211 is provided on the inner side wall of the slide block 321, the inner protrusion 3211 being adapted to be accommodated in the groove 312.
[0042] It should be noted that the inner protrusion 3211 slides along the groove 312, so that the slide block 321 can slide stably along the axial direction of the central axis 310.
[0043] In one embodiment, multiple grooves 312 are provided, and each groove 312 is distributed at equal angles on the outer side wall of the central shaft 310. Multiple inner protrusions 3211 are provided, and each inner protrusion 3211 is accommodated in each groove 312 in a corresponding manner.
[0044] It should be noted that, for example, four inner protrusions 3211 are provided, and four corresponding sliding grooves 312 are also provided. The four inner protrusions 3211 slide along the four sliding grooves 312 respectively, so that the slide block 321 can slide stably along the axial direction of the central axis 310.
[0045] like Figure 4 As shown, in one embodiment, a positioning ring 313 is provided on the central shaft 310, and the adjusting member 320 also includes a spring 323. The spring 323 is sleeved on the central shaft 310, and the spring 323 abuts against the positioning ring 313 and the slide 321 respectively. The screw ring 322 is located on the side of the slide 321 away from the spring 323.
[0046] It should be noted that the positioning ring 313 and the central shaft 310 are integrally formed. The spring 323 is sleeved on the central shaft 310, and the spring 323 abuts against both the positioning ring 313 and the slide block 321. Thus, under the elastic thrust of the spring 323, the slide block 321 reliably holds the threaded ring 322. When the threaded ring 322 is rotated and pushes against the slide block 321, compressing the spring 323, the first support arm 330 and the second support arm 340 rotate relative to each other, causing the support plate 350 to move away from the central shaft 310. When the threaded ring 322 is moved away from the slide block 321, the elastic thrust of the spring 323 pushes against the slide block 321, reliably abutting against the threaded ring 322. The first support arm 330 and the second support arm 340 rotate in opposite directions, causing the support plate 350 to move closer to the central shaft 310. Thus, when the material securing assembly 300 is removed from the drive shaft 220 and the driven shaft 230, the adjusting screw ring 322 can reliably tighten each support plate 350 around the yarn bobbin. In one embodiment, the screw ring 322 is fixed to the central shaft 310 by a mortise screw.
[0047] like Figure 3 As shown, in one embodiment, a guide seat 360 is provided on the side of the support plate 350 near the central axis 310, and a waist-shaped hole 361 is provided on the guide seat 360. Part of the structure of the second support arm 340 passes through the waist-shaped hole 361.
[0048] Thus, by installing a pin on the second support arm 340, allowing the pin to pass through the oblong hole 361, one end of the second support arm 340 can slide along the oblong hole 361. In this way, when the second support arm 340 and the first support arm 330 rotate relative to each other, the support plate 350 can stably move closer to or further away from the central axis 310.
[0049] A high-elasticity unwinding machine includes a winding device 10, a machine base, and a unwinding device. Both the unwinding device and the winding device 10 are mounted on the machine base, and the unwinding device is used to release the yarn.
[0050] It should be noted that the unwinding device is used to release the tightly wound spool onto the winding device 10, so that the yarn can be rewound from the tightly wound paper spool onto the paper spool that is fixed by the winding device 10 of this application.
[0051] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
