1. Carding machine rr type autoleveler is a double-check single-control mixed ring autoleveler. Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.

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. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.

The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). Two test points are used to control the speed change of the feed roller. The principle is: the front end of the machine is detected by the trapezoidal roller, the rear end of the machine is detected by the feeding board, and the signal is sent to the machine after being processed by the microcomputer.“Phase-shift trigger control circuit” , adjust the speed of the cotton feeding motor, change the feeding amount, and improve the evenness of the sliver length and the short and medium sliver.

a detection device for detecting the volume of the batt feed, the input signal from the converter is fed to the volume feed of the lap microcomputer, the microcomputer compares the average value and the difference value is immediately sent to the controller, Variable speed motor to vary the feed rolls, thereby changing the roll speed, feeding the batt 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 difference of applying the voltage signal to the controller, the motor speed changes to the cotton, and the feeding speed changes, so as to achieve a uniform sliver. The CSO type self-leveling device belongs to the long, medium and short segments with self-leveling device.

2. CFD-CCD self-levelling device of DK760 carding machine The DK760-type carding machine is equipped with a two-check and one-control type mixing ring self-levelling device that combines short CFD segments and long CCD segments. The CFD detection point is located between the feeding roller and the kneading board to detect the change of the thickness of the fed cotton layer; the CCD detection point is located at the front bell mouth of the machine, and the detection system outputs the change of the thickness of the sliver. Microcomputer technology based on the feedback signals from CFD and CCD detection points, and output control signals after analysis and calculation to adjust the speed of the feeding roller, so as to achieve the purpose of uniform length and short segments.

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 feeding 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. Hollingsworth 2000 carding machine is fully automatic and uniform, with a front open loop and two upper and three lower rollers 1 in front of the machine.
