Typical Autoleveler Device for Carding Machine 1.C5o Carding Machine The rr type autoleveler is a hybrid autoleveler with double check and single control. Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field.
During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. Two test points are used to control the speed change of the feed roller.
The principle is that the front of the machine adopts a stepping roller, and the rear of the machine adopts a feeding rod. Detecting device for detecting the volume of batt feed, fed by the converter to feed the input signal of the batt volume microcomputer, with the average value of the microcomputer, and immediately start the difference to the controller, the variable speed motor To change the feed rollers and thus the speed of the cotton rollers, the batt is fed so that it is as uniform as possible. After entering the bell mouth cotton web of the step detection roller, the fixing roller is detected, and the detection roller is detected by a vertical downward pressure spring, which is proportional to the displacement of the tampon part, and the continuous signal input part is provided with a microcomputer and The microcomputer comparison device is set, in the application of the voltage signal to the controller, the motor speed changes to the cotton, and the feed speed changes, so as to realize two sentences of the sliver.
Type C5O self-leveling device belongs to long, medium and short segments with self-leveling device. CFD is a card 2.DK70 type CCO as the homogenizer is equipped with a card type OK760 CFD short segment and long segment CCD select a combination of two self-loop sentence hybrid control devices. The CFD detection point is located at the junction between the roller and the cotton wool board, and the feed detects the variation of the thickness of the cotton layer; the CCD detector expansion point is located before the machine to detect the thickness variation of the output sliver.
Microcomputer signal CFO, CCD detection point feedback analysis of the output signal to adjust the calculation speed of the feed roller, the purpose of leveling long and short sections. 3. FT023 type mixing ring microcomputer self-leveler The system consists of a sensor, a cotton feeding motor and a driving development circuit, a microcomputer system controller, etc. The sensors mainly include sliver output and part of the stepped rollers. The thickness of the sliver is different. And the batt thickness sensor in the feeding part. During normal operation, the microcomputer controller can analyze and process the above-mentioned two data signals, and obtain the control input voltage for the rotation speed of the cotton roller. The quantitative output of raw sliver can achieve the purpose of reducing the standard deviation of raw sliver weight and reducing unevenness.
a4. The SLT-4 type machine is produced by two displacement sensors mounted on the cotton roller chocks to detect changes in the thickness of the feed layer. The signal output by the sensor is rectified, detected, amplified, compared, and converted into A/D. The test point and the change speed are all at the cotton roller.
5. Hollingworth platt2000 type carding machine has a front open-loop type, the front and upper rollers are each 1.5 times the drafting device, the sliver is transferred from the concave-convex roller detection device to the drafting device, and the thickness of the sliver measured by the measuring roller is measured by displacement. The sensor is converted into an electrical signal, the speed of the front roller is adjusted by the speed coupling device (constant speed acceleration and variable speed), and the speed of the DC motor is adjusted by the computer according to the required draft ratio, that is, by changing the draft multiple to achieve uniform sliver weight.
