Based on this, the concrete course of work of apparatus of the present invention is: the ramie stripes in the ramie stripes tube moves on the ramie supporting plate through berby back and conducting bar roller, ramie stripes is arranged on ramie supporting plate uniformly, forms numb sheet, feeds to give and feeds numb roller, feed numb roller and do the batch (-type) rotation, make numb sheet along periodically advancing.When numb sheet enters the feeding box, be subjected to the control of feeding comb in the feeding box, under the clamping of feeding box and feeding comb, move to open upper and lower nipper.After the fiber crops sheet entered nipper, the numb sheet of its front end dangled on the circle comb, at this moment upper and lower clamp plate closure, the numb sheet that dangles on the circle comb is gripped, and the fiber front end is pressed in the needle gap of circle comb by the small brushes that is contained on the nippers, receive the combing of circle comb, isolate staple fibre impurity simultaneously.This moment, nipper was in extreme lower position, and about the about 1mm of distance between the circle comb, the circle comb is gone up to arrange in 0~270 ° of circumference range faller gill, faller gill increases gradually with fineness along the density of its pin of direction of rotation and reduces gradually, and the circle comb is done the variable speed revolution, can guarantee the good result of circle comb to fiber like this.
Fiber after combing is able to straight, and short fiber and impurity are brushed down by the hairbrush of circle comb below, and the speed of hairbrush is faster than the circle comb, to guarantee cleaning effect, the staple fibre that is brushed down is assembled by the doffer, chops off through die, fall into the noil case, weeds etc. are thrown in the trifle in the world case through the dirt road.
When circle is combed combing, move behind the car of choosing, shift to the circle comb, fiber must enter into the car of choosing by the clump head end, and the roller of choosing is done backward rotation, and the tail end of preceding combing palpus clump is withdrawed from a length, so that and the fiber head end of new combing overlap joint.For the fiber that prevents to withdraw from is pulled away by the circle comb, interrupt down cutter play that retaining protects must clump.When the combing of circle comb finish (the circle comb forwards the angle that does not have card wire to), upper and lower nipper open and on lift, the roller of choosing this moment just changes, must give the roller of choosing by the clump head end by the shovel board holding, and with must being connected mutually by clump that the roller of choosing withdraws from, at this moment, top comb descends, its card wire is inserted in the palpus clump, makes the tail end of palpus clump receive combing.The roller of choosing quickens rotation, on interrupt cutter and descend, interrupt cutter down and rise, breaking must clump, long fiber is pulled out away.
After the palpus clump is chosen, be layered on the dermatotome of choosing, send into buncher, compressed by pressure roller, the roller that curls curls, and is gathered into ramie stripes, enters into the ramie stripes tube.
A kind of flax fibre combing sub-argument method provided by the invention, mainly be meant the ramie stripes through preliminary combing is further done one combing, two road combing, or even more multiple tracks combing, make long and short fine the separation, the thickness fiber separation, the processing procedure that fiber crops grain, impurity come off.It comprises following technological process:
Grilling---one combing---drafting---two road combing---drafting---, three road combing ...Wherein the basic process of each road combing all is the same, for:
1) at first ramie stripes is fed from feed mechanism, behind sliver, pendulum fiber crops, form numb sheet, be fed to carding mechanism;
2) numb sheet the combing stage earlier by the nipper clamping, the combing of circle comb, the car of choosing then swing is chosen, combing is carried out in top comb simultaneously in the process of choosing, the fiber crops of last top comb combing must clump be chopped off to pull away;
3) must clump after fiber chosen, be transported to buncher, and compress through pressure roller successively, after the roller that curls curls, be transported to can coiler circle bar and contain tube;
4) in combing, the process of choosing, by the hairbrush brush of the hairbrush of nipper top, circle comb below staple fibre and impurity down, to assemble by the doffer, die peels, and falls into the noil case, and carries out the assorted separation of fiber crops.
Process characteristic of the present invention is mainly reflected in following aspect:
1, adopt repeatedly carding method, twice combing at least realizes fiber separation.
During the first road combing, choose 25~35mm and space, 18# or 21# one row's faller gill are selected in top comb for use; The circle comb is selected full rack-and-pinion pin bar for use.
During the second road combing, choose 30~48mm and space, two row's faller gills are selected in top comb for use, and front row be #18 or 21#, and arrange the back is 25# or 28#; Circle comb selects for use rack-and-pinion pin bar 6 rows and faller gill formula pin bar 10 rows in conjunction with disposing, and rack-and-pinion pin bar is preceding, faller gill formula pin bar after.
During the 3rd road combing, choose 40~60mm and space, two row's faller gills are selected in top comb for use, and front row be 25# or 28#, and arrange the back is 32#; Circle comb selects for use rack-and-pinion pin bar 6 rows and faller gill formula pin bar 10 rows in conjunction with disposing, and rack-and-pinion pin bar is preceding, faller gill formula pin bar after.
2, after one combing in the end, fiber is pushed, improve fiber bending and crimpness, increase fibre cohesion by at least two pairs of curling rollers.
3, by adjusting adjusting bracket, space thereby adjust to choose to reach the purpose of adjusting the car of choosing.
The length of fiber of the choosing decision of spacing by choosing, different choosing spaced, and fiber is more as shown in table 1 down:
Choose fiber situation under spacing that table 1 is different
By table 1 as seen, choose that it is big more to space, short fiber content is low more in the ramie stripes, and average length is long more.
The combing of different number of times, the fiber short fiber rate that obtains has obvious difference, and is as shown in table 2:
Fiber index under many combing of table 2 changes
As shown in Table 2, the number of times of combing is many more, and short fiber rate, short fiber content are all low more.
Different card wire number, also different to each quality index influence of fiber.Shown in table 3,4, be the different variations (the first road combing is chosen to space and is 30mm, and the second road combing is chosen to space and is 44mm) of justifying each quality index of fiber under comb, the top comb allocation plan.
