Background
The woolen ring spinning frame is an important machine in the textile industry, and is an important process for realizing the process from roving to spinning, and in the spinning process, a drafting transmission system is an important link for realizing the process from roving to spinning, and is realized by clamping fibers by the different rotating speeds of front, middle and rear rollers and corresponding leather rollers. At present, the traditional wool spinning frame adopts mechanical drafting, a main motor drives a spindle through a rolling disc on a main shaft, and the other end drives front, middle and back rollers on the left side and the right side through a series of gear transmission (including a drafting conversion gear, a twist conversion gear, a back zone drafting conversion gear and the like which are provided with a plurality of spinning processes). When changing the spinning variety, it is necessary to stop the operation to change various gears. The wool spinning factory makes spinning technology according to different requirements of users, and then adjusts corresponding parts on equipment to achieve different spinning requirements. The drafting process is a process which is frequently required to be regulated by a ring spinning frame, and different raw materials and different yarn requirements correspond to different drafting processes. In the wool spinning factory, on the one hand, the spinning varieties are required to be changed frequently according to the market demands, on the other hand, the spinning process is required to be adjusted frequently according to the different demands of raw materials and users on yarns to meet the demands of the users, and the wool spinning is characterized by more spinning varieties and small batch, so that the operation of adjusting and changing various change gears is more frequent. Therefore, the electronic drafting of the roller driven by the servo motor through the speed reducer is particularly urgent. The existing gear transmission has the defects that:
1. The adjustment workload of the drafting process is large;
2. The drafting transmission ratio is limited by the space position, and is generally adjusted by 3-level transmission ratio, and the transmission ratio is 10-50 times by adjusting the front roller, the middle roller and the rear roller by 7-9-level transmission ratio;
3. The transmission ratio is improved along with the improvement of the whole level of the textile industry, the requirement on the adjustment precision is also improved, the gear adjustment can only be the adjustment of integer number of teeth, the step difference is relatively large, only relatively close gears can be selected, and the requirement on the draft multiple required by the process can not be completely met;
4. fancy yarns, such as slubs, segment colored yarns, and the like, cannot be spun.
In addition, for semi-worsted with the fiber raw material length in the range of 45-65 mm used in the wool spinning factory, the center distance of the front middle roller is 75mm, and the center distance of the front middle roller of normal common wool spinning is 105mm, so that the adjustment of the center distance of the roller of most of the wool spinning frames at present is difficult to realize spinning semi-worsted yarns.
The patent CN102704059B discloses a technical scheme of an electronic drafting transmission device, which can solve the problems of the part, but still has the larger problems that 1, because the torque required by the wool spinning drafting is large (one time larger than that of the cotton spinning frame with the same spindle number), the whole spinning machine adopts up to 9 synchronous belts to participate in transmission, especially the rear stage, so that the service life of the synchronous belts is cause anxiety, 2, the standard commercial gear box is adopted for primary deceleration, the structure is huge, 3, the rear roller still adopts the traditional gear transmission to change the rear zone drafting multiple, the whole spinning electronic drafting is not realized, and the fancy yarn such as slub yarn, segment colored yarn and other special yarns cannot be spun.
