Description
Technical field
The utility model belongs to the rotor spinning field of textile industry.
Background technology
Rotor spinning forms yarn by giving cotton, point comb and revolving cup cohesion twisting, obtains the yarn of Revolving cup spinning bobbin shape package through drawing yarn and coiler device.As a condition of rotor spinning, sliver is separated in cross section through combing roller and gas channel effect and only enters revolving cup again containing after the continuous fibers stream of 1-4 root fiber.This is that revolving cup is well on the necessary condition of spinning, is also the key condition that constraint improves rotor spinning output and expansion spinning count.
Centered by this key point, there are two approach to improve rotor spinning output: approach improves combing roller to the drafting multiple of sliver, ensure that the sliver of feeding Formation cross-section fiber after being separated of combing roller and air-flow is the continuous fibers stream of 1-4 root; Second approach improves rotor speed and draw yarn speed.This patent discusses the patented technology improving rotor spinning output and expansion spinning count by improving the drafting multiple of combing roller to sliver.
In recent years, rotor speed there has been and improved exponentially, and the rotating speed of the 8000rpm of combing roller is considered to its limit speed, stripped with too high combing roller rotating speed and divided card sliver, fiber can be caused to be fractureed or break, yarn strength is sharply declined.In revolving cup front end, combing roller and the separating degree of gas channel to sliver be exactly one important and need control index.
Assuming that number of fiber contained by sliver is constant, and the separating degree of gas channel to fibre stream is constant (being controlled by two ends air-flow differential), then when usable fibers stream leaves combing roller, its cross-section fibers radical is as the separating degree of combing roller to sliver.Obviously, number of fiber fewer point comb separating degree is higher, and number of fiber more points comb separating degree is lower.The separating degree of Revolving cup spinning combing roller surface fiber in resultant yarn process must acquire a certain degree, lower than this degree, just there will be the situation of stifled combing roller and stall cup, no matter spin coarse yarn or high grade yarn, be all the same to the separating degree of the fibre stream entering revolving cup, namely in continuous fibers flow section, number of fiber is 1-4 root.
Improve spinning production, just must improve the supply of sliver.Assuming that cotton strip quantity is constant, then just must promote the rotating speed of feed roll motor to improve sliver supply.In order to make sliver still reach original fibre separation index, the rotating speed of combing roller just must be promoted in proportion.But strip with too high combing roller rotating speed and divide card sliver, too much fiber can be caused to be fractureed or break, yarn strength is sharply declined.Generally, the maximum speed of combing roller is 8000rpm.What this carding capacity just causing combing roller promoted with rotor speed does not mate.
Equally, when spinning low count yarn, with sliver quantitative equally feeding, feed roll motor speed is more much larger than high grade yarn sliver feeding speed, in order to reach fibre separation index when entering revolving cup, producing low count yarn needs separating degree and higher combing roller rotating speed larger than high grade yarn.Maximum speed due to combing roller is 8000rpm, and aborning during coarse yarn, the maximum speed of combing roller limits a point supply for comb fiber, therefore the output high but vicious circle that spinning speed is not high when occurring spinning coarse yarn.
Generally speaking, the principal contradiction promoting rotor spinning machine production efficiency is: the contradiction that high combing roller rotating speed and fibre damage increase.
Summary of the invention
In order to solve the problem, the utility model adopts three fraction comb rotor spinning methods, comprises to cotton, point comb, cohesion twisting, draws yarn winding.Divide comb employing three grades of combing rollers, i.e. the 1st combing roller, the 2nd combing roller and the 3rd combing roller composition arranged in parallel.The rotating speed of three grades of combing rollers increases progressively step by step, the rotating speed of the 1st combing roller is 3000-5000rpm, and the rotating speed of the 2nd combing roller is 6000-10000rpm, and the rotating speed of the 3rd combing roller is 12000-20000rpm, the card wire density of three grades of combing rollers increases step by step, and card wire operating angle reduces step by step.
In single combing roller Revolving cup spinning, the effect of combing roller comprises two large divisions, effect strips fiber from the sliver of feed roll motor and feed plate jaw, realize dividing comb and being separated of fiber, the significantly lifting of combing roller speed, the strip active force of combing roller to fiber is increased, easily by break of CFRP, yarn quality is declined.Another effect is that fiber is transported to comb and parallel cotton fibers prior to spinning passage, and the rotating speed of combing roller is higher, and the centrifugal force of fiber is larger, and fiber is easier to be separated with combing roller and to enter comb and parallel cotton fibers prior to spinning passage.Due to needs balance strip, carded fiber, and the requirement to fiber speed when transferring to comb and parallel cotton fibers prior to spinning passage, the maximum of single combing roller rotating speed is restricted, and it is generally acknowledged no more than 8000rpm.
And adopting three grades of combing rollers, the draw ratio on the one hand by increasing progressively step by step realizes stripping and flexible drawing-off the flexibility of sliver; On the other hand by increasing the total stretch ratio of point comb system, realizing mating of carding capacity and rotor spinning ability, promoting adaptability and the raising rotor spinning output further of rotor spinning.
The rotating speed of the first combing roller is lower, when can ensure that combing roller strips fiber from feed roll motor and feed plate jaw like this, suffered by fiber to strip pulling force less, reduce the fracture and damage of fiber; The rotating speed of the second combing roller is higher than the first combing roller, and through the combing of the second combing roller, the machine-direction oriented of fiber is optimized, and horizontal transfer is mixed into one-step optimization, and the separating degree of fiber improves further; 3rd combing roller is high speed combing roller, fiber not only obtains better combing and transfer through the 3rd combing roller, now, fiber is in filament state substantially, reach higher fibre separation index, and speed gets a promotion, arrive and enter the centrifugal force requirement of comb and parallel cotton fibers prior to spinning passage, revolving cup resultant yarn can be entered in order smoothly.Speed simultaneously between three combing rollers is smaller, and contact on combing roller between fiber is more weak, and the transmission of fiber between three combing rollers has the effect of centrifugal force and air-flow, and it is very little that what fiber bore strip active force, very little to the damage of fiber.
