Description

A kind of spinning traction device

Technical field

The utility model relates to field of textiles, in particular to a kind of spinning traction device.

Background technique

During staple fiber spinning, it will usually use winding oiling machine, and the effect for winding oiling machine be to piece silk into Row oils, and many piece silks is then integrated tow by dragger, then tow is fed into the fiber barrel of lower section by feeding machine. Since the raw material of staple fiber production is mostly the bottle piece etc. recycled, tow is easy to generate broken end, this will cause dragger Traction roller is wound, and then causes to stop, and reduces production efficiency, therefore on dragger would generally be arranged one scraper to remove The piece silk of broken end reduces the generation of traction roller winding with this.However, dragger often improves to improve yield in enterprise Revolving speed realize higher output.The revolving speed of dragger continues and the scraper of traction roller abutting once increase, will necessarily be because Between the two friction aggravation and it is hot, this has just further speeded up the abrasion of scraper, and then needs to be replaced frequently scraper, not side Just and production efficiency is influenced, virtually increases the cost of production.In addition, the broken end removed during high speed spinning by scraper Piece silk, blade surface can be remained in, it is difficult to remove, if but remove the piece silk of broken end not in time, and be unfavorable for scraper to rear The removal of continuous piece silk.Further, since the frictional force of draw roll is not big enough, what is often had skidded between spinning and traction roller shows As having influenced the drawing-off effect of drafting machine, having caused outlet fiber number irregular, strength is not high, cannot reach the due quality of product.

In existing technology, it is usually to prepare two width blades to be used alternatingly to the mode of blade cooling, is maintained with reaching The effect of blade service life, but the replacement program of this blade is often complex, or even will appear Caton phenomenon, it is unfavorable In the stable operation of equipment, in addition it has been proposed that increasing the mode of the surface area of blade to achieve the purpose that heat dissipation, still, blade It is inevitably infected with upper many silk thread impurity in use, increase the surface area of blade and is arranged near knife rest more Remaining mechanical structure can all lead to the accumulation of these impurity, and then lead to the obstruction of mechanical structure, accumulation to a certain extent after The normal operation of equipment will be will affect.
