Description

Technical Field

[0001] The invention belongs to the general technical field of automatic control systems, and in particular relates to an automatic control system for stopping a full-automatic rice mill. Background Art

[0002] Automatic rice milling machine is a modern grain processing equipment that integrates automation and intelligence. For example, after the rice passes through the whitening chamber of the rice milling machine, under the action of the internal pressure of the whitening chamber, the roller or sand roller inside the whitening chamber rotates, and the air jet of the fan causes the rice to be fully rubbed between the two sand rollers to remove the rice husks on the surface of the rice, thereby obtaining smooth and bright rice.

[0003] However, the emery roller of the rice mill will wear out after long-term rotation and use. When it is worn to a certain extent, too many rough surfaces will appear on the surface of the emery roller. Too many rough surfaces will directly affect the rice milling effect of the rice mill and even cause the rice mill to jam and stop. For example, when too many rough surfaces appear on the surface of the emery roller, there is a large contact area between the rice and the surface of the emery roller. The rice will jam the emery roller and make it unable to continue rotating. The rice mill will also be overloaded due to the jamming of the emery roller (that is, the voltage of the rice mill circuit drops and the current increases), and the rice mill will shut down through automatic control.
