Description

Numb device is cut in a kind of ramie pre-processing device

Technical field

The utility model belongs to textile technology field, is related to cutting numb device 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.
