Description

The even applying device of yarn

The utility model relates to collating unit behind a kind of yarn, particularly about the coating control device of Yarn finish.

Each fibrid in the process of the various yarn final finished of system, generally all will apply lubricant (, silicone oil cured as liquid state and white oil etc.) to the finished product yarn after technologies such as spinning, dyeing, to improve sewing performance, anti-principal vertical line broken end.Present yarn coating finishing agent device, the roller type applicator is arranged, groove type applicator etc., roller type is shown in the mechanical part of Fig. 1, the debatching yarn is behind tension regulator, directly contact with last material roller top to elevating hopper, roller is done and yarn movement direction mutually during despining, take lubricant to half-turn, and a certain amount of lubricant applying is arranged to yarn, when coil winding machine is wrapped on the yarn tube but yarn oils, because being constant angular velocity, the coil winding machine main shaft rotates, the tube core is conical, when yarn is on the yarn tube, a linear diameter is being changed all the time, thereby cause the linear velocity of yarn to change along with the variation of tube linear diameter, the rotating speed of roller of meanwhile oiling is constant, therefore causes on the line finished product yarn rate tube line that oils to differ greatly between inside and outside, influences the finished product quality of yarn.CN1045825A describes a kind of groove type applicator, it makes yarn contact with bottom portion of groove, need personnel selection metering ground input finishing agent, because the linear velocity of yarn is along with simple linear diameter comes and go, coating agent consumption in the unit interval also comes and go, and still has the finished product quality of yarn problem that influences.

The purpose of this utility model is that a kind of yarn of design applies uniform control device, to improve the yarn rate that oils, guarantees the finished product quality of yarn.

The technical scheme that the utility model adopted is: the even applying device of yarn, it comprises hopper, place the last material roller in the hopper, driving motor that joins with the material loading roller shaft and the coiling electric motor that joins with the coil winding machine main shaft, and place tension regulator on the debatching yarn, it is characterized in that having by single-chip microcomputer, the yarn that revolution detector and variable speed electric motors, particularly are formed evenly applies controller, one input of described single-chip microcomputer joins with the revolution detector of being located at the coil winding machine spindle end, another input and coiling electric motor join, one output and the roller variable speed electric motors, particularly of single-chip microcomputer join, and another output and tension regulator join.

The distinguishing feature of above-mentioned design, be to design one with winding reel on the linear velocity of the yarn synchronous variable speed electric motors, particularly and the singlechip controller thereof that change synchronously, when the winding reel starting stage or the coiling more after a little while, linear velocity is little, last material roller is moving, and angular speed is also corresponding is begun progressively to increase by minimum of a value, when coiling simply directly progressively increases, the linear velocity of yarn is also progressively accelerated, last material roller rotational angular also should progressively be accelerated, by single-chip microcomputer this variation is done in time to convert, immediately assign instruction and give synchronous variable speed electric motors, particularly, make variable speed electric motors, particularly moment speed change to adapt to the needs that threading speed changes.This controller can be controlled that the material roller rotating speed is followed thickening of winding reel yarn and accelerate synchronously, the even rate that oils, make yarn tube yarn inside and outside the rate of oiling differ less than about 1%, thereby improved the finished product quality of yarn.

Fig. 3 is second embodiment of the utility model controller circuitry.

The 26S Proteasome Structure and Function of embodiment is described below in conjunction with accompanying drawing.

Structure of the present utility model is made up of mechanical part and electrical appliance part, and mechanical part its mechanical structure as shown in Figure 1 is essentially prior art, and no longer auspicious stating.Electrical appliance part comprises variable speed electric motors, particularly, control circuit and executing agency, and control section is made up of single-chip microcomputer and output circuit thereof, shown in Fig. 2,3.

Form various scaling units by single-chip microcomputer, the single-chip microcomputer input is connected on the revolution detector (8) of coiling electric motor (12) main shaft (11) one ends, the interior single-chip microcomputer of the detected signal of telecommunication via controller of revolution (13) is handled, one tunnel control tension regulator (2) work, make its clamping tension force to yarn, accelerate to reduce with the linear velocity of yarn, also having an important control circuit is that single-chip microcomputer is according to accumulative total revolution signal, calculate yarn speed at that time, again according to the linear velocity of yarn variation relation with the rate that oils, calculate the required corresponding speed of variable speed electric motors, particularly at that time, the single-chip microcomputer output order is controlled variable speed electric motors, particularly and is changed rotating speed in view of the above.

Because the spool core is generally conical shell, the shape of finished product yarn tube influence reel for yarn around the time linear velocity, linear velocity was both relevant with the position of yarn cylindrical shell of living in, and was relevant with the coil winding machine rotating speed again.Obtain from on-the-spot and test, yarn is similar to the linear velocity in centre position at the mean value of the linear velocity of cylinder top and bottom, this influence can be regarded as only is to change relevant with the coil winding machine spindle revolutions, keep the constant relatively rate that oils, just should make roller rotating speed and coil winding machine spindle revolutions that the corresponding relation of a quantity is arranged.The speed scaling unit of single-chip microcomputer is used for finishing this conversion, and result of the test can be represented with following approximate quadratic equation: V=f (N)=aN ²+ bN+c, wherein V is the roller rotating speed, and N is the coil winding machine spindle revolutions, and a, b, c are that various yarns are with respect to the different technological parameters of setting of coating oil plant.Roller rotating speed or rotational frequency scaling unit are used for roller, and minimum (yarn as various numbers is respectively 1～5 with maximum speed, 5～10, rev/min) corresponding voltage signal of output or frequency signal, and can on controller panel, set according to different product length and yam count to the requirement difference of the rate of oiling.The utility model adopts variable voltage control or frequency-adjustable speed-adjustable to implement circuit for two kinds.

Controller of the present utility model has two kinds to implement circuit, and Fig. 2 changes the rotating speed that voltage is made parameter control variable speed electric motors, particularly for the output wheel speeds, and it is made up of single-chip microcomputer and peripheral circuit.Single-chip microcomputer comprises counting unit, speed scaling unit, length setting unit, tension force voltage scaling unit and roller rotating speed scaling unit; The output of counting unit joins with the input of length setting unit and speed scaling unit respectively, and the input of the output of speed scaling unit and tension force voltage scaling unit and roller scaling unit joins.Fig. 3 makes the rotating speed that parameter is controlled variable speed electric motors, particularly for output roller rotational frequency, and it also is made up of single-chip microcomputer and peripheral circuit.The various scaling units that single-chip microcomputer comprises, except that using roller rotational frequency scaling unit to replace the wheel speeds scaling unit, other scaling unit composition and annexation and embodiment Fig. 2 are basic identical, are not repeated.
