Since the upper cleaning wiper, the lower cleaning scraper, and the countertop dust do not always fall at the same time, the main dust suction blower cannot continuously suck the countertop dust, and some of the lower scraping cotton cannot be sucked away. When the suction fan and the suction point of the table work together, the cleaning effect can be achieved. Therefore, the main dust exhaust fan can not clean the table when it is continuously operated for a certain period of time, thereby wasting power and causing great losses to the enterprise.

Because the intermittent operation can not only suck up the flannel to wipe the cotton, together with the main fan at the rear of the car to complete the cotton scraping and sucking off the dust on the countertop, and because of the continuous operation of the upper blower, it is designed to operate intermittently to save energy. However, the number of times of blowing and the number of pauses and the pause time on the existing roving frame cannot be adjusted in the PLC, thereby causing waste of electricity.
