Description

Electronic drafting driving mechanism of spinning frame

Technical Field

The invention relates to an electronic drafting driving mechanism of a spinning frame, belonging to the technical field of spinning machinery.

Background

A wool spinning ring spinning frame is an important machine in the textile industry, is an important process from rough yarn to spun yarn, and in the spinning process, a drafting transmission system is an important link from rough yarn to spun yarn and is realized by different rotating speeds of front, middle and rear rollers and corresponding leather rollers to clamp fibers. 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 rear rollers at the left and right sides through a series of gear transmissions (including a plurality of drafting conversion gears, twist conversion gears, rear zone drafting conversion gears and the like which are suitable for various spinning processes). When the spinning variety is changed, the machine needs to stop and change various changing gears. The spinning process is formulated by the wool spinning factory according to different requirements of users, and then the corresponding parts are adjusted on the equipment to realize different spinning requirements. The drafting process is a process which is frequently required to be adjusted by a ring spinning frame, and different raw materials and different yarn count requirements can correspond to different drafting processes. In a wool spinning factory, on one hand, spinning varieties are required to be frequently changed according to market requirements, on the other hand, the spinning process is required to be frequently adjusted to meet the requirements of customers according to different requirements of raw materials and users on yarns, and wool spinning is characterized by multiple 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 is driven by a servo motor through the speed reduction of the speed reducer. The existing gear transmission has the following defects:

1. the adjustment workload of the drafting process is large;

2. the drafting transmission ratio is limited by the space position, the front roller is generally adjusted by 3-level transmission ratio, the middle roller and the rear roller are adjusted by 7-9-level transmission ratio, and the transmission ratio is 10-50 times;

3. the transmission ratio is improved along with the improvement of the integral level of the textile industry, the requirement on the adjustment precision is also improved, gear adjustment can only be the adjustment of integral number of teeth, the step difference is large, only relatively close gears can be selected, and the requirement on the draft multiple required by the process cannot be completely met;

4. fancy yarns, such as slub yarns, segment-color yarns and other special yarns cannot be spun.

In addition, for the semi-worsted spinning with the fiber raw material length of 45-65 mm used in a wool spinning factory, the center distance of the front and middle rollers is 75mm, and the center distance of the front and middle rollers of normal common wool spinning is 105mm, so that the semi-worsted yarn is difficult to spin by adjusting the roller center distance of most of the existing wool spinning frames.

Patent CN102704059B "transmission device of wool spinning frame" discloses a technical scheme of electronic drafting transmission device, which can solve some of the above problems, but still has a big problem: 1. because the torque required by the wool spinning drafting is very large (one time larger than that of a cotton spinning frame with the same spindle number), the whole spinning frame of the scheme adopts up to 9 synchronous belts to participate in transmission, particularly the rear stage, so that the service life of the synchronous belts is great; 2. a standard commercial gearbox is adopted for primary speed reduction, so that the structure is large; 3. the rear roller still adopts the traditional gear drive to change the rear zone draft multiple, does not realize the electronic draft of the whole vehicle, can not spin fancy yarn, such as special yarn of slub yarn, segment color yarn, etc.
