Description

Technical Field

[0001] The utility model relates to the field of circular knitting machines, in particular to a yarn storage device driving device applied to circular knitting machines. Background Art

[0002] At present, the yarn tension is adjusted and stabilized by setting a number of annular yarn storage devices on the circular knitting machine. In order to keep the actions of each yarn storage device in good synchronization and reduce the number of motors, a motor is used to drive each yarn storage device. The specific structure is as follows: Figure 1 As shown, a driving wheel 101 driven by the motor 10 is provided, and the driving wheel 101 is located on the inner side of the yarn storage device 30; a tensioning wheel 20 is provided, and the tensioning wheel 20 is located on the outer side of the yarn storage device 30; two guide wheels 40 are provided between the driving wheel 101 and the tensioning wheel 20; a toothed belt wheel 301 drivingly connected to the yarn storage wheel (not shown in the figure) thereon is provided on each yarn storage device 30; then a toothed belt 50 is used to wrap around the driving wheel 101, the tensioning wheel 20, the two guide wheels 40, and the toothed belt wheels 301 on each yarn storage device 30 (for example: disclosed in the Chinese patent document with the Chinese authorization announcement number CN206495028U).

[0003] Among them, in the above-mentioned assembly structure, the toothed belt 50 is meshed with each toothed belt wheel 301; but in order to wrap the driving wheel 101 and the tensioning wheel 20, the back of the toothed belt 50 is in contact with the driving wheel 101, so that the driving wheel 101 and the toothed belt 50 are in smooth contact. In order to enable the driving wheel 101 to drive the toothed belt 50, it is necessary to make the pressure of the toothed belt 50 on the driving wheel 101 through the tensioning wheel 20 large enough to increase the friction between the toothed belt 50 and the driving wheel 101. Although this can meet the transmission requirements, it will cause the toothed belt to be subjected to excessive tension, which will easily cause the toothed belt to age too quickly, and then the toothed belt needs to be replaced and maintained frequently, which will result in a relatively high maintenance cost for the user. And after a period of use, the wear and deformation of the toothed belt will easily cause the driving wheel and the toothed belt to slip, which will easily lead to unstable power transmission and thus low knitting quality.

[0004] Therefore, it is very necessary to redesign the driving mechanism of the yarn storage device. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned problems and shortcomings and to provide a yarn storage device driving device for use on a large circular knitting machine. The yarn storage device driving device does not need to subject the toothed belt to excessive tension, thereby helping to reduce the aging speed of the toothed belt, and thus does not need to frequently replace and maintain the toothed belt, which can reduce the user's maintenance cost; and it will not slip even after long-term use, and its power transmission can maintain high stability for a long time, which can help to maintain high quality of knitting for a long time.

[0006] The technical solution of the utility model is achieved in this way:

[0007] A yarn storage device driving device used in a circular knitting machine comprises a rotary drive mechanism, a toothed belt, and a plurality of yarn storage devices arranged in a ring shape, wherein the yarn storage devices are provided with a yarn storage wheel and a toothed belt pulley arranged on the same rotating shaft, and the device is characterized in that a driving disk is provided on the rotary power output shaft of the rotary drive mechanism, and the driving disk is connected to the toothed belt pulley or the rotating shaft or the toothed belt in gear meshing transmission, and the toothed belt is wound around the toothed belt pulleys on each yarn storage device.

[0008] On the basis of the above structure, the utility model provides three specific gear meshing transmission connections, which are:

[0009] The first one is that a driven gear is arranged on the rotating shaft, and the driven gear is meshed with the driving disc.

[0010] The second type is that a gear portion is provided on the toothed belt wheel, and the gear portion is meshed with the driving disc.

[0011] The third type is that the toothed belt wheel is directly meshed with the driving plate.

[0012] The beneficial effects of the utility model are as follows: in the yarn storage drive device, a driving disk is arranged on the rotary power output shaft of the rotary drive mechanism, and the driving disk is connected to the toothed belt wheel or the rotating shaft or the toothed belt by gear meshing transmission. In this way, the rotary power can be more stably applied to the yarn storage device from the rotary drive mechanism, and the toothed belt only needs to be wound around the toothed belt wheel on each yarn storage device, which not only reduces the difficulty of winding the toothed belt, but also makes the driving of the toothed belt more stable and accurate, and can avoid the toothed belt from slipping. In addition, the toothed belt does not need to be subjected to excessive tension, which can help reduce the aging speed of the toothed belt, so that the toothed belt does not need to be frequently replaced and maintained, which can reduce the maintenance cost of the user. At the same time, the yarn storage drive device will not slip even after long-term use, and its power transmission can maintain high stability for a long time, which can help the knitting of the circular knitting machine maintain high quality for a long time.

[0019] like Figures 2 to 6 As shown, the utility model describes a yarn storage device driving device for use on a large circular knitting machine, comprising a rotary drive mechanism 1, a toothed belt 2, and a plurality of yarn storage devices 3 arranged in a ring shape, wherein the yarn storage devices 3 are provided with a yarn storage wheel 32 and a toothed belt wheel 33 which are arranged on the same rotating shaft 31. To achieve the purpose of the utility model, a driving disk 11 is provided on the rotary power output shaft of the rotary drive mechanism 1, and the driving disk 11 is connected to the toothed belt wheel 33 or the rotating shaft 31 or the toothed belt 2 in gear meshing transmission, and the toothed belt 2 is wound around the toothed belt wheel 33 on each yarn storage device 3.

[0020] In the yarn storage drive device, a driving disk 11 is arranged on the rotary power output shaft of the rotary drive mechanism 1, and the driving disk 11 is connected to the toothed belt wheel 33 or the rotating shaft 31 or the toothed belt 2 by gear meshing transmission. In this way, the rotary power can be more stably applied to the yarn storage device 3 from the rotary drive mechanism 1, and the toothed belt 2 only needs to be wound around the toothed belt wheel 33 on each yarn storage device 3, which not only reduces the difficulty of winding the toothed belt 2, but also makes the driving of the toothed belt 2 more stable and accurate, and can avoid the toothed belt 2 from slipping. In addition, the toothed belt 2 does not need to be subjected to excessive tension, which can help reduce the aging speed of the toothed belt 2, so that the toothed belt 2 does not need to be frequently replaced and maintained, which can reduce the maintenance cost of the user. At the same time, the yarn storage drive device will not slip even after long-term use, and its power transmission can maintain high stability for a long time, which can help the knitting of the circular knitting machine to maintain high quality for a long time.

[0021] In the actual manufacturing process, the rotary drive mechanism 1 can adopt the following two structures: the first one is as follows: Figures 3 to 5As shown, the rotary drive mechanism 1 is a drive motor, and the drive disc 11 is mounted on the power output shaft of the drive motor; secondly, the rotary drive mechanism 1 includes a motor and a reduction gearbox, the reduction gearbox is drivingly connected to the power output shaft of the motor, and the drive disc 11 is arranged on the power output shaft of the reduction gearbox. This can meet the actual manufacturing and use requirements.

[0022] On the basis of the above structure, the utility model provides three specific gear meshing transmission connections, which are:

[0023] The first one, such as Figure 3 As shown, a driven gear 34 is provided on the rotating shaft 31, and the driven gear 34 is meshed with the driving disk 11. In this way, the power of the driving disk 11 can be stably transmitted to the rotating shaft 31 through the driven gear 34, so that the yarn storage wheel 32 can be driven to rotate stably, thereby ensuring that the yarn storage device driving device has a very high reliability.

[0024] The second type, such as Figure 4 As shown, the toothed belt wheel 33 is provided with a gear portion 35, and the gear portion 35 is meshed with the driving disk 11. In this way, the power of the driving disk 11 can be stably transmitted to the toothed belt wheel 33 and the rotating shaft 31 through the gear portion 35, so that the yarn storage wheel 32 can be driven to rotate very stably, thereby ensuring that the yarn storage device driving device has a very high reliability.

[0025] The third type, such as Figure 5 As shown, the toothed belt wheel 33 is directly meshed with the driving disk 11. This not only helps to control the manufacturing difficulty, but also enables the power of the driving disk 11 to be very stably transmitted to the toothed belt wheel 33, thereby being able to very stably drive the yarn storage wheel 32 to rotate, thereby ensuring that the yarn storage device driving device has very high reliability.

[0026] like Figure 6 As shown, when the drive disc 11 is connected to the toothed belt 2 by gear meshing transmission, the drive disc 11 can be a gear or a belt disc with teeth. Such transmission will not slip, thereby ensuring that the transmission is very stable.

[0027] like Figure 6 As shown, in order to make the toothed belt 2 transmission have high stability, at least one tensioning wheel 4 can be provided to tension the toothed belt 2, thereby making the gear meshing closer and more stable, thereby helping to further improve the reliability and applicability of the yarn storage device drive device.

[0028] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
