The invention discloses an automatic uncovering protection device capable of increasing the use safety of a centrifugal machine. The automatic uncovering protection device comprises a first proximity switch arranged on an uncovering driving arm, an oil cylinder action baffle is arranged on a piston rod of an uncovering oil cylinder, an uncovering proximity switch matched with the oil cylinder action baffle is arranged on a cylinder body of the uncovering oil cylinder, and when a machine cover is completely opened, the oil cylinder action baffle triggers the uncovering proximity switch; a mounting seat is arranged on a machine cover hinging seat, a cylindrical safety seat is arranged on the mounting seat, an air cylinder is arranged at one end of the safety seat, and the end part of a piston rod of the air cylinder extends into the safety seat and is provided with a pin shaft; the uncovering proximity switch is arranged on the uncovering driving arm, when the machine cover of the centrifugal machine is completely opened, a signal sent by the uncovering proximity switch is triggered, so that the piston rod of the air cylinder pushes the pin shaft to trigger the uncovering proximity switch to send an uncovering interlocking signal; and a return proximity switch is arranged on the safety seat, and when the piston rod of the air cylinder drives the pin shaft to retract, the pin shaft triggers the return proximity switch to give out a centrifugal machine cover closing signal.
Description
technical field [0001] The invention relates to an automatic cover opening protection device for a centrifuge. Background technique [0002] The existing cover opening protection device of the centrifuge is composed of a safety seat and an eye nut. After the centrifuge cover is opened, the operator needs to operate on site to twist the eye nut so that the end is embedded on the driving arm for opening the cover. In order to avoid accidental falling of the machine cover, before the machine cover is closed, the lifting eye nut is manually screwed out of the cover-opening driving arm. The cover opening protection device adopts a purely mechanical structure to realize protection and has no interlocking device with the equipment, which poses certain safety hazards to the on-site operators. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic cover opening protection device for a centrifuge that increases the ...
