Description

Warp rebeaming machine unwinding tension control device
Technical field:
The utility model relates to a kind of weaving preparing machine, is applicable to tencels such as glass fibre, especially a kind of warp rebeaming machine unwinding tension control device.
Background technology:
The warp rebeaming machine unwinding tension control device of prior art mainly adopts following two kinds of structures at present:
First kind is to control unwinding tension with magnetic powder brake, and with a magnetic powder brake, the output axle head of magnetic powder brake is by the double reduction transmission and link to each other through the axle axle head through axle for each.Resistance size by the control magnetic powder brake is controlled unwinding sheet yarn tension.The major defect of this method is:
1. control accuracy is poor.Under the situation of input same current, the moment of torsion that magnetic powder brake provides can be subjected to influence of various factors, and along with the heating of magnetic powder brake, its temperature can raise as in use, and variations in temperature can influence its moment of torsion; The power that magnetic itself is magnetized can influence its moment of torsion; The uniformity that magnetic distributes in brake can influence its moment of torsion etc.Therefore in use be difficult to accurately adjust in time its moment of torsion.
2. heating is serious.Because of magnetic powder brake provides moment of torsion by frictional resistance, in this pedestal, can only adopt the structure that brake is fixed, output shaft rotates, slip power is very big, and heating is serious.
3. be not suitable for the requirement of high speed hightension.Because magnetic powder brake the degree of heat and speed and tension force magnitude relationship are close, under the situation of high speed hightension, its theoretical caloric value surpasses the ability to bear of magnetic powder brake, and magnetic powder brake can't satisfy the requirement of high speed hightension.
4. maintenance is tired.Because there is problem of aging in magnetic, its moment of torsion will reduce after use a period of time, change magnetic, can influence to produce and the raising production cost.
Second kind is with the pedestal design of steel band damping control unwinding tension, just connecting a brake disc through the axle axle head, draws steel band to be pressed on the brake disc with cylinder, controls unwinding sheet yarn tension with the frictional force between steel band and brake disc.The major defect of this method is that steel band provides the weighing apparatus moment of torsion, along with diminishing of beamed yarn linear diameter, the arm of force of yarn pulling force also diminishes, the tension force of yarn just constantly increases, tension force differs and reaches 2.5 times when dishful head and blank panel head, in order to reduce this tension difference, usually and the axle process in to transfer the air pressure of cylinder several times to regulate the resistance of steel band, can't realize the tension force unwinding of weighing; And the steel band damping also can't provide hightension, also incompatible high speed.
The utility model content
The purpose of this utility model is to provide a kind of above-mentioned shortcoming that overcomes, the constant a kind of warp rebeaming machine unwinding tension control device of sheet yarn tension when beamed yarn line external diameter is changed.
For achieving the above object, the technical scheme that the utility model adopted is: this warp rebeaming machine unwinding tension control device, comprise electrical apparatus control system, and atmospheric control, cord roller, reducing motor through axle, is clapped to attach together and is put brake, brake disc; By being supported on through axle bearing on the axle bearing seat, cord roller fits on the frame with rolling bearing units, it is characterized in that through axle: dancer is contained on the roll shaft that floats with bearing; The roll shaft that floats fits over respectively on two dancer bearing blocks by bearing, two dancer bearing blocks are separately fixed on the slide block, two slide blocks fit over respectively on the guide rail, and two guide rails are separately fixed on the rail brackets, and two rail bracketses are separately fixed on the corresponding frame medial surface; Tooth bar on the two ends of unsteady roll shaft are equipped with gear and are fitted over the frame medial surface is meshed; On the dancer bearing block of left end the position sensor connecting plate is housed, is furnished with the position sensor slide block on the position sensor connecting plate, position sensor is fixed on the frame; A dancer cylinder plinth respectively is housed on two dancer bearing blocks, on dancer cylinder plinth, be respectively equipped with the device that is connected with the piston rod of dancer cylinder, the dancer cylinder is fixed on the dancer cylinder block, and the dancer cylinder block is fixed on the frame.
Described a kind of warp rebeaming machine unwinding tension control device, it is characterized in that: the device that the described piston rod with the dancer cylinder set respectively on dancer cylinder plinth is connected, this device is for being provided with dancer cylinder nipple pin on dancer cylinder plinth, one end of dancer cylinder nipple pin and dancer cylinder joint is vertical configuration and flexibly connects, and the other end of dancer cylinder joint is connected with the piston rod of dancer cylinder.
The utility model beneficial effect compared with prior art:
Adopt a kind of warp rebeaming machine unwinding tension control device of said structure, the control strip yarn tension is to cooperate by motor and dancer to realize when unwinding, can be alternating-current variable frequency motor or AC servo motor etc. through spindle motor, the speed or the output torque of motor are controlled by electrical apparatus control system, the tension force size is by the size decision of dancer cylinder thrust, when air pressure one timing, the thrust of cylinder is just certain, when dancer is mobile within the specific limits, air pressure does not change, the thrust of cylinder is also constant, does not therefore influence the size of sheet yarn tension, has achieved permanent tension force unwinding; Just can adjust the tension force size easily as long as regulate the size of air pressure.When motor response time and degree of regulation are not enough, dancer moves forward and backward the effect of playing the storage yarn or putting yarn, thereby guarantee the constant of tension force, also can store yarn through the circular runout of axle and dancer, cord roller and be used for reducing influence, thereby improve the stability of unwinding quality and unwinding the sheet yarn tension by dancer.
