2 stage transmission wheels connected on individual secondary transmission band drive line sending unit to carry out line sending simultaneously, can carry out dual drive, i.e.,
Making one of secondary transmission band go wrong also can normally be driven, and so as to improve transmission stability, improve working (machining) efficiency.This
Outward, the utility model carries out line sending and lubrication by arranging line sending unit, lubricates block by roller and wedge shape and yarn is moistened
It is sliding, make wedge shape lubricate block by spring and keep up mobile trend, wedge shape profit slide position can be automatically adjusted and roller is made
Laminating is kept with wedge shape lubrication block, it is ensured that lubricant effect, it is to avoid yarn weares and teares or break in transmission, improves transmission stability
And product quality.Therefore, the utility model can not only improve transmission stability, yarn broken string, abrasion be prevented, also with processing
Good and good product quality the advantage of efficiency high, lubricating efficiency.
