Abstract
The utility model relates to a four-apron drafting system for a spinning frame in the spinning industry. In the back drafting zone, a back upper roller can be changed into a middle upper roller, an upper apron can pass round an upper pin and the back upper roller, and the upper pin is provided with a distance separating block. A back lower roller is provided with a lower apron passing round a lower pin, the lower pin is arranged on the sliding seat of the back lower roller through a lower pin plate, and the lower pin is provided with a stopping block which can prevent the lateral movement of the lower apron. Because the upper and the lower two aprons can be increased at the back zone, the drafting process of the spinning frame can be changed from the drafting mechanism with three-roller and double-apron to the drafting mechanism with three-roller and four-apron. Compared with the double-apron drafting mechanism, the drafting ability of the four-apron drafting mechanism can be increased twice, and the yarn qualities can be improved. The back lower apron can be pressed by a lower pin pressing plate with a cuniform plate, having simple structure, and the device can be cleaned conveniently.
Description
Technical field
The utility model relates to the drafter of fine spining machine, is particularly relevant to the back area draft mechanism of fine spining machine.
Technical background
Fine spining machine is the key equipment of spinning industry such as cotton, hair, silk ribbon, fiber crops, thin,tough silk, suede, and native system is the executing agency of fine spining machine, and its performance directly influences the quality and the output of spinning.Existing fine spining machine all adopts three roller double belt drafting mechanisms, this mechanism has three bottom rolls of only transmission and corresponding with it passive three of itemizing to list roller, three row bottom rolls from after forward rotating speed improve successively, thereby reach the purpose that roving-drafting is become spun yarn.Upper and lower two aprons are housed respectively on middle top roller and middle bottom roller participate in the proparea drawing-off.The first break draft district does not have apron, Here it is three roller double belt drafting mechanisms, and its proparea drafting multiple of this drafter is generally at 20～30 times, because the back zone is simple roller draft.For guaranteeing yarn quality, its drafting multiple generally is no more than 1.3 times.This shows that the first break draft district of three roller double belt drafting mechanisms is tangible weak links, the restriction that it is serious the raising of the whole drawing-off ability of fine spining machine.The patent No. is 96107383 " drafting system that is used for high-count worsted machine ", the three-apron drafter is disclosed, it is on the basis of original double belt drafting mechanism, on the top roller of back, a upper leather ring and last Xiao have been installed additional, and only adorned following Xiao in the bottom of epithelium posterius circle, thereby total draft can force rate be doubled originally.But this three-apron drafter also has certain shortcoming, be exactly at draw zone thereafter, the synchronous drawing-off of rove bar and upper leather ring, and be sliding friction between rove bar bottom and the following Xiao, because upper leather ring has certain pressure to following Xiao, increased the same frictional force between Xiao down of rove bar, this just makes the stressed non-equilibrium state that always is in of the upper and lower of rove bar, has influenced yarn quality.The patent No. be ZL01243901.0's " fine spining machine four apron drafting arrangements ", rear roller and the back under Xiao's upper ring cap after one under apron, an elastic device tensioning is leaned in back apron down, well solved the problem of rove bar upper and lower part unbalance stress, obtained good effect, but because the existence of the elastic device of tensioning apron, cumbersome when making in actual production sweeping machine, the strict factory of management generally cleans once weekly, so its weak point is also arranged.
Summary of the invention
The purpose of this utility model provides that a kind of drawing-off ability is higher, yarn quality is better, easy to operate, simple in structure, fine spining machine four apron drafting arrangements being convenient to clean.
For achieving the above object, the utility model adopts following technical scheme:
Fine spining machine four apron drafting arrangements described in the utility model comprise roller stand, preceding bottom roll is housed on roller stand, middle roller slide and rear roller slide, on the middle roller slide middle bottom roller is housed, the back bottom roll is housed on the rear roller slide, the preceding apron down of walking around following Xiao and tension bracket is housed on middle bottom roller, corresponding to preceding bottom roll, front upper roller is equipped with in the top of middle bottom roller and back bottom roll, middle top roller and back top roller, the anterior epithelium cornea circle of going up Xiao before walking around is housed on the middle top roller, be equipped with on the back top roller and walk around the epithelium posterius circle that Xiao is gone up in the back, spacing block is housed on Xiao on the back, be equipped with on the back bottom roll and walk around back Xiao's back apron down down, back Xiao down is installed on the rear roller slide, it is characterized in that: be provided with down Xiao's pressing plate between Xiao and the rear roller slide under the back, following Xiao's pressing plate comprises fixedly connected fixed head that meets at right angles and tensioning plate.
Block is equipped with on Xiao down in the back.
This fine spining machine four apron drafting arrangements have kept the part and the structure of existing fine spining machine front draft zone.In the first break draft district, original back top roller is removed, replace with original middle top roller, on the top roller of back, Xiao is housed, epithelium posterius circle of ring set outside the two, on Xiao spacing block being housed on the back,, reach the spinning different cultivars frictional force between upper and lower apron is required different purposes to adjust the distance between upper and lower Xiao.On the bottom roll slide of back Xiao under the back is housed, back Xiao down is fastened on the rear roller slide by Xiao's pressing plate down, and following apron of Xiao's upper ring cap under rear roller slide and back is equipped with block on Xiao under the back, prevents down the apron lateral displacement.
When work, back bottom roll drives back apron rotation down, because back top roller applies certain pressure to the back bottom roll, so, back top roller rotates under the drive of back bottom roll synchronously, then top roller also drives the epithelium posterius circle simultaneously and rotates synchronously, just formed a continuous and soft friction field that is synchronized with the movement with the rove bar in the first break draft district like this, control drafted rove bar effectively, make its inner filament keep motion clocklike, reach the purpose that improves the drawing-off ability, improves yarn quality.
After on the fine spining machine this four tape drawing mechanisms being installed, its beneficial effect is:
1. the total draft ability improves greatly, because realized also that in the back zone two aprons grip, the drafting multiple of back zone can reach more than 5 times, simultaneously because enter the wadding bar in proparea with tightr originally, also corresponding raising before the drawing-off energy force rate in proparea is improved, the total draft ability can reach more than 150 times.
2. because the raising of fine spining machine total draft ability, quantitatively can strengthening of rove improved the output of Speed frames, thus can reduce Speed frames join the platform number, reduced production cost, save equipment investment.
3. therefore fine spining machine drawing-off wide adaptability can not only adapt to few kind and also adapt to Multi-varieties and Small-batch Production in enormous quantities with the spun yarn that spins different numbers with a kind of rove.
4. yarn quality is good.Because at former and later two draw zones, the fiber in drafted all obtains active and effective control, particularly floating fiber and no longer random motion of short flannel, thereby the uniformity that becomes sliver to do improves greatly, and can spin the more yarn of high-count.
5. be convenient to cleaning.Because Xiao's pressing plate is easy to take out down, so solved the trouble of cleaning equipment substantially.
