The speed of the flower wheel of the ultrasonic lace machine is too fast, which may be caused by the following reasons:

1. Device setup issue: It may be due to the device being set too fast in the initial setup or subsequent adjustments. This may be due to operator error or intentional acceleration of speed in order to speed up work.

2. Control system malfunction: The control system of the ultrasonic lace machine is responsible for controlling the speed of the flower wheel. If there is a malfunction in the control system, it may cause an abnormal increase in the speed of the flower wheel.

3. Motor issue: The motor is a key component that drives the rotation of the flower wheel. If the motor malfunctions or is damaged, it may affect the speed of the flower wheel, resulting in excessive speed.

4. Transmission system issue: The transmission system is responsible for transmitting the power of the motor to the flower wheel. If there is a malfunction in the transmission system, such as damage or looseness of components such as chains and sprockets, it may also cause abnormal flower wheel speed.

To solve the problem of the flower wheel speed being too fast, the following methods can be tried:
1. Check device settings: Ensure that the device settings are correct and the flower wheel speed is within a reasonable range.

2. Check the control system: Check if the control system is operating normally and if there are any fault prompts.

3. Check the motor: Check if the motor is running normally and if there are any abnormal sounds or vibrations.

4. Check the transmission system: Check whether the chains, sprockets, and other components of the transmission system are intact and whether they are loose or damaged.

If none of the above methods can solve the problem, it is recommended to contact professional maintenance personnel for inspection and repair. At the same time, to ensure the safety and stable operation of the equipment, it is recommended to regularly maintain and upkeep the equipment.
