Abstract

The utility model provides reeled yarn line density and irregularity testing arrangement, comprises pedestal, cheese socket, spindle, twizzle, and adjustable springs tensioner remembers long device, variable-frequency motor, around ryce, and controller, yarn; Described cheese socket is fixed on pedestal, spindle is inserted on cheese socket, winding yarn on spindle, yarn is through twizzle, by adjustable springs tensioner, corresponding tension force is applied to yarn again, yarn through after adjustable springs tensioner by the long device of note, be then wrapped in have variable-frequency motor on ryce, the motion process of yarn is controlled by controller.The beneficial effects of the utility model do the note growth device feature of testing equipment, and change conventional yarn line density length metering method, adopt the line density result of this testing of equipment more stable, deviation ratio is little, closer to actual value.

Description

Reeled yarn line density and irregularity testing arrangement

Technical field

The utility model belongs to field of textile equipment, especially relates to a kind of reeled yarn line density and irregularity testing arrangement.

Background technology

The test of the current yarn linear density especially line density of cop or cone yarn be by repeatly, thread yarn horizontal metroscope, batch certain number of turns, be multiplied by according to thread yarn horizontal metroscope wire frame perimeter length and batch the number of turns and obtain the length of shaking and getting yarn, then yarn is carried out oven dry to weigh, convert and draw yarn linear density index.The method of testing of irregularity adopts thread yarn horizontal metroscope to shake the yarn getting many group certain lengths, weighs respectively, calculate its coefficient of average deviation or the coefficient of variation.There is following problem in the method: the measurement result degree of accuracy is low.When yarn is wound up on the ryce of sample skein winder, due to winding volume number >=100, even if sample skein winder is provided with traversing gear to reduce the degree of yarn overlying, but in fact yarn overlying degree is still very serious, yarn linear density is larger, overlapping degree is larger, and the degree that the numerical value of yarn test is bigger than normal is more serious.

Summary of the invention

For reduce reel for yarn around time traversing and be wound around the problem that the overlapping length of yarn caused grows partially, guarantee the accurate of length of yarn, the purpose of this utility model is to provide that a kind of structure is simple, simple to operate, testing length is closer to the reeled yarn line density of actual value and irregularity testing arrangement.

The technical solution of the utility model is: reeled yarn line density and irregularity testing arrangement, and described reeled yarn line density and irregularity testing arrangement comprise pedestal, cheese socket, spindle, twizzle, adjustable springs tensioner, remembers long device, variable-frequency motor, around ryce, controller, yarn;

Described cheese socket is fixed on pedestal, spindle is inserted on cheese socket, winding yarn on spindle, yarn is through twizzle, by adjustable springs tensioner, corresponding tension force is applied to yarn again, yarn through after adjustable springs tensioner by the long device of note, be then wrapped in have variable-frequency motor on ryce, the motion process of yarn is controlled by controller.

The advantage that the utility model has and good effect are: owing to adopting technique scheme, the note growth device feature of testing equipment is done according to Yarn filoplume and bar, change conventional yarn line density length metering method, the metering method of length of yarn is wound around by original counting wire frame the mode that the number of turns is multiplied by wire frame girth, is adjusted to Electric automatic control and remembers rectangular formula.

In figure: 1, pedestal; 2, cheese socket; 3, spindle; 4, twizzle; 5, adjustable springs tensioner; 6, long device is remembered; 7, variable-frequency motor; 8, around ryce; 9, controller; 10, yarn.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is elaborated.

As shown in Figure 1, the utility model reeled yarn line density and irregularity testing arrangement, described reeled yarn line density and irregularity testing arrangement comprise pedestal, cheese socket, spindle, twizzle, adjustable springs tensioner, remembers long device, variable-frequency motor, around ryce, controller, yarn;

The course of work of this example:

The operations such as normal damping are carried out with reference to GB/T 4743-2009 " mensuration of textiles package skein yarn method line density " tested sample.Then on thread yarn length meter, shake the yarn getting many group certain lengths according to standard-required, generally (common yarn) shakes and gets the yarn that length is 100 meters.Because the overlap of yarn causes the length of drying the specimen yarns sample of weighing in the actual Qu Binghou of shaking road program to be greater than 100 meters in reeling process, and the length increased becomes large with the increase of length, line density, causes the actual test data recorded bigger than normal in the yarn linear density of reality.Adopt the device of this patent application can solve this problem well, adopt electronics automatically to remember long device record length of yarn, be wrapped in and be equipped with on the ryce of variable-frequency motor, then dry, weigh, calculate the line density of sample, more traditional length gauge counting method is more accurate.

First yarn is correctly placed on socket or spindle, by twizzle, according to the tension force that the applying of different yarns line density is different, then by note long device, be wrapped in have variable-frequency motor on ryce.This avoid traditional reeling device to roll up the next yarn traversing of number scale long band and to superpose the unexpected length brought.Record the length of yarn more accurately, make the line density of test sample more accurate, irregularity is also more accurate.

For 27.8tex Quality Pure Cotton Yarn Production, shake and get 100 meters of yarns, pre-tension 13.9cN is set, thread ryce rotating speed is 200r/min, after weighing, according to mass value, calculate its physical length by its actual line density value and will increase about 80cm, therefore the yarn linear density value of gained is bigger than normal.

Adopt the 27.8tex purified cotton yarns (cheese) of two kinds of different equipment test calibration respectively, test 20 groups of yarns respectively, show that the test result deviation ratio adopting common thread yarn horizontal metroscope is 5%, and the deviation ratio of the line density value that the innovative means designed by adopting is tested is 0.7%, therefore designed innovative means device meets actual value more.Carried out again the contrast test of many groups of different linear density range yarns, its result trend is consistent simultaneously.

Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
