Feeding device of screening machine for producing ink powder

Abstract

The invention relates to a feeding device of a screening machine for producing ink powder. A feeding pipe flange is fixed with a feeding pipe; two shaft sleeves are respectively fixed on the feeding pipe flange and the feeding pipe; two oiliness seal rings are respectively arranged in the two shaft sleeves; a feeding screw is arranged in the feeding pipe and in the shaft sleeves provided with theoiliness seal rings; the other end of the feeding screw passes through the feeding pipe flange and is connected with connecting sleeves arranged in the shaft sleeves provided with the oiliness seal rings; a speed reducer flange is fixedly connected with the feeding pipe flange through the connecting rods; an output shaft on an alternating current single-phase speed reducer is fixedly connected with the connecting sleeves. By the feeding device, time and labor are saved during installation, maintenance and debugging of the alternating current single-phase speed reducer and the feeding screw, the maintenance cost is saved, waste of an ink product is reduced, the product yield is improved, and most important, dust leakage is effectively controlled, and environmental protection is achieved.

Description

technical field [0001] The invention relates to toner production equipment, in particular to a screening machine feeding device for toner production. Background technique [0002] In the existing toner production equipment, the feeding part of the original system is composed of an AC single-phase reducer, a feeding screw, a feeding pipe, and a shaft sleeve of the feeding pipe. The AC single-phase reducer is directly connected to one end of the feeding pipe. The connecting seat is directly connected, the transmission shaft of the reducer is connected to the feeding screw in the feeding pipe, and the other end of the feeding screw is supported by the shaft sleeve to form the entire feeding part. The disadvantages of this design are: 1. Since the original design is that the output shaft of the AC single-phase reducer is directly connected with the feeding screw in the feeding pipe, not only the installation, maintenance, and debugging are laborious and time-consuming, but also ...

AI Technical Summary

Problems solved by technology

The disadvantages of this design are: 1. Since the original design is that the output shaft of the AC single-phase reducer is directly connected with the feeding screw in the feeding pipe, not only the installation, maintenance, and debugging are laborious and time-consuming, but also the occurrence of failures is relatively frequent; 2. The AC single-phase reducer is directly connected to the feeding pipe, and there is no way to install a sealing device in the middle. As a result, the finished toner is easy to seep out from the feeding pipe and directly enter the reducer part of the AC single-phase reducer, which is easy to cause damage to the reducer. The poor rotation of each bearing leads to the burning of the reducer; 3. The other end of the feeding screw and the feeding pipe is only fixed and supported by the shaft sleeve without a sealing device, which not only easily leaks waste caused by toner, but also pollutes the working environment
