Structure Composition of Powder Press Ball Machine

Structure Composition of Powder Press Ball Machine


1. The feeding part mainly realizes the quantitative feeding to ensure that the material evenly enters the counter-roll room. The screw feeding device is driven by an electromagnetic speed regulating motor and rotates through the belt pulley and worm reducer, forcing the pressed material into the main inlet and outlet. Because of the constant moment characteristic of the electromagnetic speed regulating motor, when the pressure of the screw feeder is equal to that of the main machine, the constant pressure of the feed can be maintained to stabilize the quality of the pellets. If the feeding quantity is too large, the electric overload of the feeding device will occur; if the feeding quantity is too small, the ball will not be formed. Therefore, skilled operation is an important condition to ensure the normal operation of pressure ball.
 
2. In the transmission part, the main transmission system is motor-triangle belt-reducer-open gear-roll. The main engine is powered by an electromagnetic speed regulating motor, which is transmitted to the driving shaft by a bar-pin coupling through a transdermal belt pulley and a cylindrical gear reducer. The driving shaft and the passive shaft run synchronously through the open gear. The rear of the passive bearing seat is equipped with a hydraulic device. Hydraulic protection device is a hydraulic pump which injects high-pressure oil into the hydraulic cylinder to produce axial displacement of the piston. The front joint top of the piston rod is on the bearing seat to meet the production pressure requirement.
 
3. The forming part mainly refers to the main part and the core part is the roll. When there is too much feed between the two rollers or metal blocks, the piston rod of the hydraulic cylinder is under pressure and overload, the hydraulic pump will stop, the accumulator will buffer the pressure change, the relief valve opens and returns oil, and the piston rod shifts to make the gap between the rollers widen so that the hard objects pass through the rollers, and the system pressure will return to normal, which can protect the rollers from damage. The machine can adjust the pressure according to the requirement of balling density, and the production is flexible and flexible.
