[0031] It should be noted that the frequency converter is electrically connected to the control module 1.

[0045] Working principle:

[0046] The control module 1 sends a signal to the frequency converter to control the operation of the frequency converter, so that the frequency converter controls the operating speed of the spindle motor. At the same time, the corresponding control instructions are sent to the control module 1 through the input module 2. The control module 1 receives the control instructions to control the corresponding opening and closing of the spindle drive module 3, the stirring module 4 and the spray module 5.
