Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grooved drum type winding machines, in particular to a slow start system for a grooved drum type winding machine. Background Technique
[0002] Traditionally, a grooved drum type winding machine usually uses a main frequency converter to drive dozens of winding motors on one side at the same time, and each motor is controlled to run and stop by an operating relay. During the winding process, when the yarn breaks on one spindle, the operating relay controlling the motor of that spindle disconnects and the motor stops running, while the other motors continue to run with the main frequency converter. After reconnecting the yarn and restarting the motor, since the driving main frequency converter is still operating at a relatively high frequency, when the operating relay closes, the motor speed will suddenly accelerate from 0 rpm to the winding speed (generally 3000 rpm). At this time, the rapid acceleration process can easily cause the yarn to break again, and the yarn tension will also increase, resulting in an increase in the density of the wound yarn, affecting the subsequent dyeing process. Therefore, a smooth acceleration process is required when the motor starts to avoid this situation. Content of the Utility Model

[0005] Further, a main frequency converter is arranged on the main control circuit.

[0011] Embodiment 1
[0012] As Figure 1 shown, a slow start system for a grooved drum winding machine includes: a power supply circuit and a plurality of winding motors. The winding motors are connected to the power supply circuit through a main control circuit. A running relay K1 is provided on the main control circuit. A slow start circuit is provided between the main control circuit and the power supply circuit, and a slow start relay K2 is provided on the slow start circuit.
[0013] Embodiment 2
[0014] As Figure 1 shown, a slow start system for a grooved drum winding machine includes: a power supply circuit and a plurality of winding motors. The winding motors are connected to the power supply circuit through a main control circuit. A running relay K1 is provided on the main control circuit. A slow start circuit is provided between the main control circuit and the power supply circuit, and a slow start relay K2 is provided on the slow start circuit. A main frequency converter is provided on the main control circuit.
[0015] Embodiment 3
[0016] As Figure 1 shown, a slow start system for a grooved drum winding machine includes: a power supply circuit and a plurality of winding motors. The winding motors are connected to the power supply circuit through a main control circuit. A running relay K1 is provided on the main control circuit. A slow start circuit is provided between the main control circuit and the power supply circuit, and a slow start relay K2 is provided on the slow start circuit. A slow start frequency converter is provided on the slow start circuit.
[0017] As Figure 2As shown, when the winding machine is running normally, the running relays of all winding motors are energized and driven by the main frequency converter. After the electronic anti-piling function is enabled, the main frequency converter runs at a high speed with frequency oscillation. The slow start frequency converter always outputs intermittently. According to the start time setting, the speed increases from 0 to the winding speed of the main frequency converter and then quickly returns to 0. When any winding motor needs to be restarted after yarn breakage, the slow start relay will wait for the slow start window time to appear and be energized within the first-arriving window. As the frequency of the slow start frequency converter increases, the speed of the winding motor slowly increases. After reaching the winding speed of the main frequency converter, the slow start relay is de-energized and the running relay is energized. The winding motor line is switched to continue to be driven by the main frequency converter to complete a start-up process.
[0018] During the start-up process, the slow start relay is only energized when the speed of the slow start frequency converter is 0, preventing sudden changes in motor speed that could cause yarn breakage and tension changes. After bringing the speed of the winding motor to the winding speed of the main frequency converter, the motor is switched to the line of the main frequency converter, reducing the sudden change in speed during the start-up process and achieving a smooth start for the single-spindle motor. This system reduces the probability of yarn breakage during start-up, and the smooth acceleration during start-up also keeps the yarn tension stable, ensuring the consistency of the winding density and facilitating subsequent dyeing processes.
[0019] The present utility model adds a slow start relay to each winding motor. When single-spindle start-up is required, the start relay is energized, and the slow start frequency converter is used to drive the motor to smoothly accelerate from a stationary state to the normal winding speed. The slow start relay is de-energized, and the running relay is energized to switch the motor to the main frequency converter line for normal operation, thus completing a smooth start-up process.
