An automatic clamping apparatus for paint mixers which applies a direct downward force on a paint container to prevent movement during the mixing operation, includes a clamping plate, a linear actuator, and a current sensor. The clamping plate is secured to the moving end of a vertically aligned linear actuator which moves the clamping plate up and down onto a paint container. The current sensor detects when the clamping plate is pushing against the top of the paint container and the power to the actuator is adjusted accordingly to maintain securing force on the paint container.

An automatic clamping apparatus for paint mixers which secures a paint container to the bottom plate of a shaking compartment during a shaking process, the shaking compartment defined by side frames and a top frame, comprising, in combination: a clamping plate having an upper and lower surface and a center, said clamping plate located within said shaking compartment, said upper and lower surfaces being parallel with a horizontal plane; actuating means for effecting vertical movement of said clamping plate by exerting a vertical force thereon, said actuating means having a lower end and an upper end, said lower end connected to said center of said clamping plate, said actuating means fixedly secured to the shaking compartment; sensor means for detecting a resistant force against said actuating means, said sensor means having an output corresponding to said resistant force; and control means for adjusting said vertical force exerted by said actuating means, said control means being responsive to said output from said sensor means, wherein said control means decreases said vertical force exerted by said actuating means when said sensor means detects a predetermined amount of said resistant force on said actuating means, and said control means reverses said vertical force when the shaking process is completed, thereby causing said actuating means to retract and lift said clamping plate.
