AI Technical Summary
The material storage sensing device of traditional plastic color mixing machines is prone to false alarms caused by the magnetic induction sensor due to the rotating plate being blocked by the mixed material, which leads to machine shutdown and affects production.
Design a material feeding sensor structure to prevent false alarms in a plastic color matching machine. By setting a movable slide plate and a fixed plate under the rotating plate, and using a cylinder with holes and a connecting shaft to enable flexible rotation of the rotating plate, a magnet is set in the storage box to cooperate with the magnetic induction sensor to prevent the rotating plate from being blocked by the mixed material and ensure accurate operation of the magnetic induction.
This effectively avoids false alarms from magnetic induction sensors, reduces the labor intensity of workers, ensures production continuity, and prevents machine downtime caused by false alarms.
