Description
Technical field
The utility model relates to widely used spooling equipment in a kind of textile chemical fiber industry, particularly the servo unwinding device of a kind of frequency conversion.
Background technology
At present, various looms weft yarn when wefting insertion is all mode unwinding from yarn cylinder of axially pulling out, every unwinding one circle, and weft yarn will be twisted once, the twist occurs and change.Weft yarn for some flat, in weaving process, weft yarn forms clot and twisted phenomena because unwinding causes nature twisting, can not be smooth inweave among fabric, cause the feel of fabric coarse, while is inconsistent because weft yarn turns the direction after song, light being reflected, can produce dim spot fragmentarily at fabric face, cause cloth cover not attractive in appearance.
Utility model content
The purpose of this utility model is to provide a kind of servo unwinding device of frequency conversion that can weave smooth and fabric attractive in appearance in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the servo unwinding device of the resulting a kind of frequency conversion of the utility model, comprise revolving cup, yarn cylinder, spindle, belt pulley, belt, drive unit, creel and power supply, in described revolving cup, be provided with spindle, spindle is arranged on creel, spindle end cover has belt pulley, described belt pulley is connected by belt, described yarn cylinder is placed in above the spindle in revolving cup, described drive unit is connected with belt, described drive unit comprises motor, after described power supply, be connected with timer, timer is connected with numerical control adjuster, numerical control adjuster connecting drive device, the motor of described drive unit is variable-frequency motor.
In order not affect the unwinding of yarn when the spindle High Rotation Speed, the height of described yarn cylinder is lower than the height of revolving cup, and the axis of described belt pulley and the axis of revolving cup overlap, and described spindle is arranged on the center of revolving cup and belt pulley.
In order to specialize unwinding device, the yarn cylinder number on described creel is nine.
The servo unwinding device of a kind of frequency conversion that the utility model obtains compared with prior art, its advantage is: because yarn cylinder is in rotary course, kept yarn at the uniform velocity to extract out, the not clot of yarn of releasing is also non-warping, can be smooth inweave, weave smooth cloth, and smooth cloth also there will not be the phenomenons such as dim spot.
Accompanying drawing explanation
Fig. 1 is the servo unwinding device structural representation of frequency conversion of the present utility model;
Fig. 2 is unwinding device single structure schematic diagram of the present utility model.
In figure: revolving cup 1, yarn cylinder 2, spindle 3, belt pulley 4, belt 5, drive unit 6, timer 7, numerical control adjuster 8, creel 9, power supply 10.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figures 1 and 2, the servo unwinding device of a kind of frequency conversion that the utility model provides, comprise revolving cup 1, yarn cylinder 2, spindle 3, belt pulley 4, belt 5, drive unit 6, creel 9 and power supply 10, in described revolving cup 1, be provided with spindle 3, spindle 3 is arranged on creel 9, spindle 3 end covers have belt pulley 4, described belt pulley 4 is connected by belt 5, described yarn cylinder 2 is placed in above the spindle 3 in revolving cup 1, described drive unit 6 is connected with belt 5, described drive unit 6 comprises motor, described power supply 10 is connected with timer 7 below, timer 7 is connected with numerical control adjuster 8, numerical control adjuster 8 connecting drive devices 6, the motor of described drive unit 6 is variable-frequency motor.
The height of described yarn cylinder 2 is lower than the height of revolving cup 1, and the axis of described belt pulley 4 and the axis of revolving cup 1 overlap, and described spindle 3 is arranged on the center of revolving cup 1 and belt pulley 4.
The number of the yarn cylinder 2 on described creel 9 is nine.
Complete the whole process of unwinding yarn:
When switching on power 10 time, timer 7 starts timing, conveys to 8 one signals of numerical control adjuster simultaneously, makes drive unit 6 drive belts 5 to rotate, and the yarn that yarn cylinder is 2 li starts unwinding.Nine yarn cylinders 2 all rotate towards an identical direction under the drive of belt 5, and the yarn in nine yarn cylinders all starts unwinding simultaneously.Along with the time of 7 li of timers is fewer and feweri, numerical control adjuster 8 regulates the running speed of the motor of 6 li of drive units, makes the speed of motor more and more faster.The rated acceleration of motor speed regulates by numerical control adjuster 8.
Time of timer 7 the insides designs is according to the running speed of yarn cylinder 2, to determine the complete required set of time of unwinding of yarn.Yarn cylinder 2 operation is fast, and unwinding required time is just short, in like manner, operation slow, required time of unwinding is just long, according to the time of the complete required set of time timer 7 of this unwinding.
The rated acceleration of motor regulates by numerical control adjuster.Yarn when unwinding, yarn twist with the fingers to seriously explanation accelerate not, unwinding yarn too much knotting explanation accelerate excessive, according to the yarn on yarn cylinder 2 number, in conjunction with the rated acceleration of required set of time motor.
For example: while switching on power, yarn in yarn cylinder 2 starts unwinding, the speed showing on numerical control adjuster 8 is 100, and the yarn on yarn cylinder 2 is complete needs of unwinding 30 minutes at the uniform velocity, and timer 7 is just set as 30 minutes, the numerical value that numerical control adjuster 8 per minute shows rises 10, the acceleration of motor is per minute is 10, and, after 30 minutes, what numerical control adjuster 8 showed is 400 several times, unwinding yarn is complete, and timer stops timing.
