Automatic adjustment technology of gap between roller and ring die of granulator
The gap adjustment between the pressure roller of the granulator and the ring die is an important part of the operation of the granulator. If the gap is adjusted properly, the pelletizer will have high output, low energy consumption, good pellet quality, small wear of the pressure roller and ring die, and long service life: otherwise, the animal feed business pelletizer will not work normally and the pellet quality will not be guaranteed. If the gap is too small, the ring die will wear out severely and even burst. This puts forward higher requirements for the operator of the granulator, who needs a wealth of knowledge about the adjustment of the pressure roller. In order to reduce the influence of unstable factors of human operation. At the same time, in order to reduce human work intensity and improve production efficiency, the technology of automatic adjustment of the gap between the pressure roller and the ring die came into being. It is mainly composed of an oil cylinder execution system, an angle sensor and a PLC control system. The function of the oil cylinder execution system is to push the pressure roller to rotate clockwise or counterclockwise, even if the gap between the pressure roller and the ring die increases or decreases; The function is to sense the change of the pressure roller angle and transmit the change signal to the PLC control system; the PLC control system is responsible for converting the change of the pressure roller angle into the change of the gap between the pressure roller and the ring die and compare it with the set gap value. This determines the movement direction and size of the cylinder execution system until the actual clearance and the set clearance are consistent within the allowable error range. The system can use the on-site touch screen as the interface of "man-machine dialogue", which is easy to operate and has high adjustment accuracy. The gap error between the pressure roller and the ring die can be controlled within ±0,1 rum, and it can be used at any time during the work of the granulator. Tuning, greatly improving work reliability and work efficiency. The labor intensity is reduced, the wear of the pressure roller and the ring die is reduced, and the service life is greatly extended.
It can be seen from the above discussion that with the vigorous development of my country’s modern aquaculture and feed industry, feed equipment has made great progress in technology. In terms of animal feed production technology, the widespread adoption of automated control technology in all links has greatly improved Production efficiency and product quality reduce the work intensity of people, ensure the stability and safety of the pelleting process, and provide high-performance key feed pelleting equipment for the construction of modern feed factories.
