Description
Technical Field
The invention relates to the field of internal mixer control, in particular to a lower top bolt safety control system of an internal mixer.
Background
The internal mixer, also called kneader, is mainly used for plasticating and mixing rubber. An internal mixer is a machine which is provided with a pair of rotors which are of specific shape and relatively rotate, plasticates and mix polymer materials in a clearance way under a closed state with adjustable temperature and pressure, and mainly comprises a banburying chamber, the rotors, a rotor sealing device, a feeding and pressing device, a discharging device, a transmission device, a machine seat and the like. The quality of the sizing material mixed by the internal mixer is mainly determined by mixing temperature, charging capacity, rotor rotating speed, mixing time, upper bolt pressure, rotor type and the like except for charging sequence.
When the internal mixer cleans and maintains the lower top bolt, the internal mixer needs to be hung up for halt, then an operator drives the machine to a manual body in an upstairs operation cabinet, the lower top bolt is opened, then the operator operates, and in the actual operation process, if other operators enter a working area for private operation, great potential safety hazards exist.
