The Xinjinlong of the carding machine has a large rotational inertia, and the starting system is slowed down. In addition to requiring the motor to work with a large starting torque, you should also pay attention to the dynamic performance in the design of the transmission parts. 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.
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).
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. The old carding machine mainly adopts the dead and live belt pulleys and the method of slipping a belt to gradually improve the start-up of Xinjinlong, which is troublesome to operate, can not form correct and effective control and can start the running time, and shortens the service life of the transmission belt. . When the speed of Xinjinlong increases, this old method will lead to sharp reduction of wear and heat of the transmission belt, so we should not choose to use it.
Using the friction clutch installed on the Xinjinlong shaft of the high-yield carding machine to realize the gradual development and start-up of Xinjinlong, it can not only ensure that my country's electric motor can maintain the basic rated speed and torque when starting, and is less overloaded by the motor. It heats up and can accurately control the start time. In newly designed high-yield cards, the starting friction clutch technology has been changed to be installed on the shaft of the electric motor as a social centrifugal slider type friction clutch (Figure 2-9). Because of the high speed of these motors, in order to further reduce the size of the clutch and reduce the requirements for the starting torque of the motor, the economic management effect is significant.
Since the centrifugal friction clutch can transmit electric power to slip, the friction force is proportional to the product of a short angular velocity. Since the centrifugal force, and the friction torque is proportional to the centrifugal force, the centrifugal force is proportional to the square of the rotational speed, the centrifugal friction clutch slider output power will be Proportional to the cube of the rotational speed. Therefore, the centrifugal friction clutch slip DIN is designed as a high-speed motor shaft. Inertia, workload, speed and clutch power are related to the clutch hook member support hook-up time.
Flash occupies most of the power consumption of Xinjinlong needle machine, so only the power consumption cylinder can start to use flower approximation.
