Description

Technical Field

[0001] The utility model relates to the field of knitting machinery, in particular to a power transmission structure of a circular knitting machine. Background Art

[0002] At present, in order to make the large disc gear on the circular knitting machine rotate stably, the following driving structure is generally adopted: the power output by the driving motor is transmitted to the large disc gear through the pulley assembly, the gearbox, and the driving gear in sequence; the pulley assembly is respectively connected to the power output shaft of the driving motor and the input end of the gearbox, the driving gear is mounted on the power output shaft of the gearbox, and the large disc gear is meshed with the driving gear.

[0003] At present, when adjusting the circular knitting machine, it is often necessary to rotate the large disc gear to check the debugging results. Since there are many transmission components on the circular knitting machine, it is difficult to successfully debug the machine at one time. Generally, the large disc gear needs to be started and stopped many times. Among them, there are two ways to rotate the large disc gear:

[0004] The first method is to start the drive motor to drive the large plate gear to rotate. Since the large plate gear needs to be started and stopped many times during the machine adjustment process, the drive motor needs to be started and stopped many times, which consumes more electric energy.

[0005] The second method is for workers to manually turn the large disc gear to make it rotate. Although this method does not use electrical energy, due to the limitation of the gearbox, a very large force is required to turn the large disc gear, so manual rotation is very laborious and the efficiency is not very high, which will affect the convenience and efficiency of the machine adjustment. At the same time, this will also lead to a relatively high labor intensity for the workers.

[0006] Therefore, it is very necessary to design a power transmission structure of a circular knitting machine to solve the above-mentioned technical problems. Utility Model Content

[0007] The purpose of the utility model is to solve the above-mentioned problems and shortcomings and to provide a power transmission structure for a circular knitting machine. The application of the power transmission structure can not only make the machine adjustment without using electric energy, but also greatly improve the convenience of manual rotation, which can achieve the purpose of saving electricity and reducing labor intensity, thereby facilitating the improvement of the convenience and efficiency of machine adjustment.

[0008] The technical solution of the utility model is achieved in this way:

[0009] A power transmission structure of a circular knitting machine comprises a gearbox and a driving shaft for driving a large disc gear. The structure is characterized in that a clutch is provided between the driving shaft and the power output shaft of the gearbox, which can transmit power between the gearbox and the driving shaft and disconnect the power transmission between the driving shaft and the gearbox.

[0010] Preferably, the driving shaft body comprises a rotating shaft and a gear, the rotating shaft is connected to the power output shaft of the gearbox through a clutch, and the gear is arranged on the rotating shaft.

[0011] Preferably, the power transmission structure also includes a driving motor and a transmission belt. A driving pulley is mounted on the power output shaft of the driving motor, a driven pulley is mounted on the power input shaft of the gearbox, and the transmission belt is wound around the driving pulley and the driven pulley.

[0012] Preferably, the inner end of the power input shaft of the gearbox protrudes out of the gearbox and forms a drive shaft.

[0013] The beneficial effects of the utility model are as follows: on the power transmission structure, a clutch is provided between the drive shaft and the power output shaft of the gearbox, which can transmit power between the gearbox and the drive shaft, and can disconnect the power transmission between the drive shaft and the gearbox. This can not only meet the normal transmission of power, but also disconnect the power transmission between the drive shaft and the gearbox through the clutch when adjusting the components on the large plate gear, which can make manual rotation of the large plate gear very labor-saving, thereby being conducive to improving the convenience and efficiency of adjusting the machine, and being conducive to reducing the labor intensity of workers, and in this way, there is no need to connect the power supply during the adjustment of the components on the large plate gear, which can achieve the purpose of saving electricity. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0015] like Figure 1 As shown, the power transmission structure of a circular knitting machine described in the utility model includes a gearbox 1 and a driving shaft 2 for driving a large plate gear. In order to achieve the invention purpose of the utility model, a clutch 3 is provided between the driving shaft 2 and the power output shaft of the gearbox 1, which can transmit power between the gearbox 1 and the driving shaft 2 and can disconnect the power transmission between the driving shaft 2 and the gearbox 1.

[0016] In the power transmission structure, a clutch 3 is provided between the drive shaft 2 and the power output shaft of the gearbox 1, which can transmit power between the gearbox 1 and the drive shaft 2 and disconnect the power transmission between the drive shaft 2 and the gearbox 1. This can not only meet the normal transmission of power, but also disconnect the power transmission between the drive shaft 2 and the gearbox 1 through the clutch 3 when adjusting the components on the large plate gear, which can make manual rotation of the large plate gear very labor-saving, thereby improving the convenience and efficiency of the adjustment, and can help reduce the labor intensity of workers, and in this way, there is no need to turn on the power supply during the adjustment of the components on the large plate gear, which can achieve the purpose of saving electricity.

[0017] like Figure 1 As shown, the driving shaft body 2 includes a rotating shaft 21 and a gear 22. The rotating shaft 21 is connected to the power output shaft of the gearbox 1 through a clutch 3, and the gear 22 is arranged on the rotating shaft 21. The gear 22 is engaged with the large plate gear 10. Such a driving shaft body 2 is very simple and reliable, which is not only convenient for manufacturing, but also conducive to stably driving the large plate gear to rotate.

[0018] In the actual manufacturing process, the rotating shaft 21 and the gear 22 can be made into an integral structure, or the gear 22 can be installed on the rotating shaft 21 in a set manner. Both methods can meet the needs of actual manufacturing and use.

[0019] The clutch 3 is an existing clutch that can both transmit power and disconnect power transmission, such as an overrunning clutch, an electromagnetic clutch, a tooth clutch, a hydraulic clutch, a pneumatic clutch, etc.; at the same time, an existing clutch that can be manually disconnected can also be used; this can meet the actual manufacturing and use requirements.

[0020] like Figure 1 As shown, the power transmission structure of the circular knitting machine also includes a driving motor 4 and a transmission belt 5. A driving pulley 6 is mounted on the power output shaft of the driving motor 4, and a driven pulley 7 is mounted on the power input shaft of the gearbox 1. The transmission belt 5 is wound around the driving pulley 6 and the driven pulley 7. This can generate very stable and reliable power, thereby providing a more stable power for the circular knitting machine, and such a structure is relatively simple and can be easily manufactured.

[0021] like Figure 1 As shown, in the actual manufacturing process, the driving pulley 6 and the driven pulley 7 can both be V-pulleys, and the transmission belt 5 can be a V-belt accordingly, which can make the power transmission more stable and reliable.

[0022] like Figure 1 As shown, the inner end of the power input shaft of the gearbox 1 protrudes out of the gearbox 1 and forms a drive shaft 11. This can provide more power for the circular knitting machine, so that more components can be driven by one drive motor, which can help reduce the manufacturing cost and difficulty of the circular knitting machine.

[0023] In the actual manufacturing process, the power output by the driving shaft 11 can be used to drive the yarn feeding mechanism of the circular knitting machine, so that one driving motor 4 can be used to drive more mechanisms.

[0024] like Figure 1As shown, when the large disc gear 10 is adjusted, the clutch 3 is in a disconnected state (different types of clutches have different disconnected states, which can be disconnected by external intervention or automatically), which can facilitate workers to manually rotate the large disc gear 10, saving labor, saving electricity, and improving the efficiency of adjusting the machine. When the circular knitting machine needs to perform knitting operations, the clutch 3 can be in a coupled state, so that the power output by the gearbox 1 can be stably transmitted to the rotating shaft 21 and the gear 22, so that the large disc gear 10 can be stably driven by the gear 22, and then the normal knitting needs can be met.

[0025] 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.
