Description
Technical field
The utility model belongs to textile technology field, the comb fiber crops sub-wire device being related in a kind of ramie pre-processing device.
Background technique
Ramie is the specialty in China, and domestic and international ramie spinning equipment falls behind, but spinning cotton equipment is relatively advanced very much, and cotton
It spins fibre length and is generally 16~38mm, the numb technique of existing spinning are as follows: softener-steel wire producing machine-pre-drawing machine-combing machine-grilling
Machine-combing drawing frame-fly frame-fine sand machine, complex process, and inefficiency, flax product relative mass is poor, the reason is that
The evenness fault of ramie yarn and very big, different in size, length has a long way to go, the hardly possible such as fiber flexibility and finished product elasticity, mellowness
To ensure.
The essence of spinning processing be by straightening of fibers it is arranged in parallel after, twist resultant yarn.Fiber is longer, stretches arranged in parallel
It is more difficult to, therefore, from the point of view of current spinning unit, the spinning line of the short cotton fiber of length (30mm or so) is most short, each process
Machine speed it is also most fast, the horizontal highest of overall technology;And the fibers such as the longer fiber crops of length, hair, thin,tough silk (length generally 70~
110mm), not only its spinning line is longer than cotton spinning, and its speed of production also it is slower than cotton spinning very much.Although coming from the angle of resultant yarn
It sees, fiber is longer, and the strength of resultant yarn can be bigger, but in fact, the theoretical research by our early periods is spinned with a large amount of
It is experimentally confirmed that after fibre length reaches a certain level, the increase of fibre length to the contribution of strength with regard to very limited, and length
Shorter fiber, the performances such as uniformity after resultant yarn significantly improve.In general, the average strength of yarn is able to satisfy substantially and wants at present
Ask, and user more be pay close attention to yarn strength it is irregular.Therefore, ramee length can be shortened by handling, is made completely
Its requirement for meeting cotton spinning spinning, then carries out spinning processing on cotton spinning equipment, using advanced cotton spinning platform, promotes ramie
The development of spinning.
Patent " a kind of ramie cotton spinning processing method and its crush cutting equipment used " (publication number:
CN102181972A in), a kind of new ramie spinning method, i.e. crush cutting ramie cotton Yarn spinning method, processing flow are proposed
Are as follows: degummed ramie → softening → pre- crush cutting → crush cutting → pre- simultaneously → silver lap → combing → drafting (2~3) → rove → spun yarn.It should
Technology utilizes a kind of crush cutting equipment, biggish jaw curable grip is formed by the way of hydraulic or Pneumatic Pressure, by forward and backward
Long fibre in ramie is led the length broken to 30~50mm by the speed difference of roller, and spinning is then carried out on cotton spinning equipment and is added
Work improves the versatility and interchangeability of ramie spinning equipment and cotton spinning equipment, utilizes advanced cotton spinning platform to a certain extent,
Promote the development of ramie spinning.But since ramee is thick, hard, intensity is big, cause crush cutting machine utilization big, energy consumption is high,
Crush cutting inefficiency, and as in degummed ramie due to fiber bending, tangling existing for coma, fiber knot it is especially more, these are fine
Dimension group, fiber knot can not be separated by crush cutting, be loosened, in addition, failing to lead there is also significant proportion in the ramee after crush cutting
Disconnected overlength fiber, above-mentioned phenomenon causes it in the machining of Cotton Drawing Frame, fly frame and spun yarn, extremely difficult, easily goes out
The phenomenon that existing drawing-off is not opened, and seriously affected final yarn quality.
To solve this problem, scholar has also been proposed method (the clock sea cotton ramie for carrying out crush cutting using ramie yarn
The Shanghai numb converter spinning technical study [D]: Donghua University, 2013.), spinning equipment is to ramie before this method utilizes existing ramie
The phenomenon that being processed, forming crush cutting again after yarn, avoid coma present in degummed ramie crush cutting, fiber knot, after making
The spinnability of the processes such as continuous drafting, rove and spun yarn is greatly improved, and yarn quality also increases.But in crush cutting
When yarn, also due to ramee is thick, hard, intensity is big, cause the load of crush cutting equipment big, energy consumption is high, crush cutting low efficiency
Under, not only yield is very low, but also equally exists significant proportion in the ramee after crush cutting and fail to lead disconnected overlength fiber, after making
Continuous spinning process, especially rove and spinning process drawing-off are difficult, though using slip draft, also when there is drawing-off not open phenomenon hair
It is raw, keep resultant yarn process and yarn quality unsatisfactory.
Before converter spinning, spinning processing of the ramie on cotton spinning equipment is fallen primarily directed to the combing in the long bast fibre spinning of ramie
Fiber crops, process are as follows: ramie combing noil → opening or cleaning → combing → drafting (2) → rove → spun yarn.But the raw material of the technique is
The noil that combing process generates in the long hemp spinning process of ramie, numb grain, runner and impurity are more, and short fibre content is high, lead to resultant yarn
It is of low quality.Therefore, part factory also then exists to improve yarn quality using direct cut staple after degummed ramie softening
It spins on cotton spinning equipment, process are as follows: degummed ramie fiber → softening → cuts fiber crops → opening or cleaning → combing → drafting (2) → thick
Yarn → spun yarn, but because in degummed ramie due to fiber bending, tangling existing for coma, fiber knot it is especially more, also can not after cutting
Avoid there are a large amount of overlength fibers, numb grain and runner, the retrofits such as combing, subsequent spinning can not be both carried out on cotton spinning equipment
Yarn, especially rove and spinning process because it is long stapled there are due to drawing-off it is difficult, can only therefore can only using slip draft
For processing thick branch, low-grade ramie yarn.
Utility model content
In view of the above-mentioned problems, proposing the comb fiber crops sub-wire device in a kind of ramie pre-processing device, its purpose is to ramie
Flaxen fiber carries out sub-wire refinement, homogenizes its fibre diameter, makes it suitable for cotton spinning equipment and processed.
Comb fiber crops sub-wire device in a kind of ramie pre-processing device, which is characterized in that this comb fiber crops sub-wire device includes rack
And guide housing, for the guide housing in having cylindrical shape jaggy, uniform rotation is connected with a comb fiber crops roller in the guide housing, described
Guide housing and comb there is gap between numb roller, the eckling machine structure further include one can it is intermittent by ramie beam to guide housing with
The feed device fed in the gap between numb roller is combed, there is a convex pillow, the numb roller surface of the comb on the inner wall of the guide housing
The first cutter with several groups comb teeth and a strip, each group of comb teeth include several slivers, form comb between adjacent sliver
Slot;The width of the comb slot is gradually increased on combing numb roller rotation direction.
