A Classifier Feeding System for Toner Production

Abstract

The present invention relates to a classifier feeding system for toner production. It includes coarse crushing silo and feeder silo, and also includes flap valve, electromagnetic pneumatic drive valve, material level gauge and control circuit. The flap valve is set between the coarse crushing silo and feeder silo; The plug-in end of the drive valve is plugged and fixed on one side of the flap valve, and the connection line of the control end is connected to the control circuit; the level gauge is set in the feeder bin, and the connection line of the control end is connected to the control circuit. Due to the installation of a flap valve between the coarse crushing silo and the feeder silo, the abnormality of powder feeding by the drive motor of the feeder due to the powder leakage of the flexible funnel is avoided; the feeding control is implemented for the feeder , reduce the pressure on the feeder, make the feeder work at a constant speed throughout the working process, and improve work efficiency.

Description

technical field [0001] The invention relates to a feeding system, in particular to a classifier feeding system for toner production. Background technique [0002] Classifier feeding system is one of the main systems of toner production line. In the existing production technology, the coarse crushing silo is directly connected with the hopper of the classifier feeder, and the coarse crushed material is sucked directly into the coarse crushing silo by negative pressure at a certain time interval, and then fed into the feeder. The paddle outside the flexible funnel beats the flexible funnel repeatedly, relying on vibration to transport the coarse crushed material to the conveying screw of the feeder, and finally conveys it to the classifier through the conveying screw for grading. The defects of this working method are: ① Due to the repeated beating of the paddle on the flexible funnel, the flexible funnel breaks and leaks powder, which causes the feeder to drive the motor to ...

AI Technical Summary

Problems solved by technology

The defects of this working method are: ① Due to the repeated beating of the paddle on the flexible funnel, the flexible funnel breaks and leaks powder, which causes the feeder to drive the motor to enter the powder, causing the working current to increase and cause failure; ② relying on the paddle The way of slapping the feeding itself determines the uncontrollable feeding amount. The sudden increase of the screw workload and the insufficient processing capacity may occur. The former causes the deformation of the feeding screw, and the latter affects the output; ③ Due to the regular feeding , in many cases, a large amount of coarse crushed materials are gathered in the silo of the feeder, and the pressure on the feeder is very high. On the one hand, the flexible hopper is easily deformed due to long-term pressure, and on the other hand, the coarse crushed Too much will cause poor whereabouts and affect output

Not only does it increase maintenance costs, but it also increases the number of downtime, which directly affects production
