Embodiment 1
[0022] like Figure 1 to Figure 6 As shown, the drafting transmission mechanism is composed of a headstock drafting transmission system 2 and a rear synchronous drafting transmission system 3 fixedly installed on the drafting transmission mechanism bracket 1 . The drafting drive system 2 of the headstock is composed of three motors that respectively drive the front roller, the front section of the middle roller, and the front section of the rear roller of the long spinning frame through the transmission chain. The synchronous drafting drive system 3 at the rear of the car is driven by two motors through the drive chain to respectively drive the middle roller rear section and the rear roller rear section of the long spinning frame.
[0023] The output shaft of the front roller motor 201 is provided with the first driving pulley 202, the first driving pulley 202 is connected with the first passive pulley 205 on the front roller reduction box 204 input shaft by the first synchron...

A drafting transmission mechanism of a full-electronic drafting long spinning frame comprises a head drafting transmission system and a tail synchronous drafting transmission system, wherein the fronthalf sections of a front roller, a middle roller and a rear roller are respectively driven by three synchronous servo motors in the head drafting transmission system through a transmission chain, andthe rear half sections of the middle roller and the rear roller are respectively driven by two synchronous servo motors in the tail synchronous drafting transmission system through the transmission chain. After the full-electronic drafting transmission system is adopted, the tail synchronous mechanism does not need to be arranged, the working load of the front roller is effectively reduced, the yarn forming quality and the equipment stability of the long spinning frame are improved, meanwhile, the drafting parameter adjustment is realized by inputting the drafting process to a PLC through a control end display screen, the technology adjustment efficiency is improved, and the equipment maintenance cost is reduced.
Description
technical field [0001] The invention relates to the field of textile machinery, in particular to an all-electronic drafting transmission mechanism for long spinning frames. Background technique [0002] In the drafting transmission mechanism of the traditional spinning frame, the main motor drives the main shaft through the rear of the car, and the main shaft enters the front of the car through a series of gear meshes to drive the drafting mechanism of the car head. In the long spinning frame with more than 600 spindles, since each roller bears different loads during the process of drafting the yarn, the longer the rollers, the more out-of-synchronization between the rollers will be caused, which will affect the yarn quality. In order to reduce this unfavorable factor, the middle and rear roller synchronous transmission mechanism is added at the rear of the long spinning frame, and the front roller enters the rear of the vehicle through the synchronous transmission mechanism...
