Description

Drafting device of drawing frame
Technical field
The utility model belongs to technical field of textile machine, is specifically related to a kind of drafting device of drawing frame.
Background technology
Known spinning process comprises opening picking, comb and parallel cotton fibers prior to spinning, drafting, rove, spun yarn and winder.The function of drafting device of drawing frame is by sliver (also claiming strip) drawing-off, and its structure comprises and is arranged on one group of drawing rollers that is in frame and that jointly driven by headstock and gear-box, equal with the quantity of one group of drawing rollers and be arranged on guide roller (also claiming modified roller) in frame rotationally corresponding to the position before coordinating one of one group of drawing rollers work group of pressure roller (pressure roller is called roller by the industry be accustomed to) and in corresponding to the front roller in one group of drawing rollers and one group of pressure roller between pressure roller be bearing in rotationally above one group of drawing rollers in frame rotationally.
Glue to twine and twine the phenomenon on guide roller because drafting device of drawing frame there will be fiber in the process of drafting of sliver in pressure roller is particularly sticky; specifically; fiber glues the roll body surface twined in pressure roller and guide roller; particularly for the large sliver of those electrostatic as the sliver of aramid fiber matter; pressure roller and guide roller are more outstanding by the sticky phenomenon twined; necessary downtime in time, thus the extra work burden and the working strength that had both added workman, affect working (machining) efficiency again.But, if not in time or claim not timing downtime, so will certainly affect the yarn quality of subsequent technique, cause defect yarn.
" drafter of drawing frame " that Chinese invention patent Authorization Notice No. CN101570906B recommends can solve the problems of the technologies described above, specifically can see the 0016 to 0019 section, the description of this patent.But still there is following shortcoming in this patent formula: because clean cord cover (patent claims " clean curtain ") adopts flannelette to make usually, otherwise be difficult to the effective cleaning action played pressure roller and guide roller, thus be previously positioned at cellulose flock on pressure roller and guide roller and short velveteen and considered the phenomenon often occurring stiffly adhering to clean cord after cleaned cord cover is removed and put to be worth doing, and be not enough to the abundant sucking-off of suction port (suction port is connected with dust exhaust apparatus pipeline) from the suction hood corresponding to clean cord cover top.So just as utilizing one piece of reason losing clean wiping cloth wiping desk, the expection of industry cannot be reached by the cleaning effect of the obstinate clean cord cover attached of short velveteen bits to pressure roller and guide roller.Current solution is: regularly or aperiodically under stopped status, utilize the industry or domestic dust collector that are equipped with separately or similar device to overlap clean cord by workman's (guarantor's pincers worker) and implement specific aim and clean; thus the cleaning mode of this passive type had both added the workload of protecting pincers worker and plant maintenance personnel, affected again the production efficiency of drawing frame to a certain extent.Especially, artificially implement clean effect and the whether thorough full subjective judgement with operator of clean-up performance to clean cord cover, the quality of cleaning effect is relevant to the sense of responsibility of operator simultaneously.
