A feeding device and method for a graphite carbon brush forming machine

Abstract

The invention discloses a feeding device for a graphite carbon brush forming machine and a method thereof. The feeding device comprises a feeder, an expansion furnace, a mixing tank, a forming tank and a collecting box. The feeder is fixedly connected to the top of the expansion furnace; and the bottom of the expansion furnace is fixedly connected with the top of the mixing tank by a pipeline andan elbow. The bottom of the mixing tank is fixedly connected with the top of the forming tank by a conveying pipe; the forming tank is fixedly arranged above the connecting box; and a bottom plate ismovably connected between the forming tank and the collecting box. The feeder includes a first telescopic rod, a mounting plate, a first motor and a first mixing shaft; the first telescopic rod is fixedly inserted into the upper end surface of a top plate; the top plate is fixedly connected to the top of the expansion furnace; a thermal insulation layer is arranged at the outer side of the expansion furnace; and a blanking hopper is fixedly connected to the bottom of the expansion furnace. According to the invention, the feeding device is designed reasonably and is convenient to operate; a problem of low product quality is solved; the work efficiency is improved; and the feeding device is easy to promote.

Description

technical field [0001] The invention belongs to the technical field of graphite carbon brushes, and in particular relates to a feeding device and method for a graphite carbon brush forming machine. Background technique [0002] Graphite carbon brushes, also called graphite brushes, are widely used in many electrical equipment as a sliding contact. The brush (Brush) is an important component of the motor, responsible for conducting current between the rotating part and the stationary part. Because it is mostly made of graphite, it is also called carbon brush. [0003] The main component of carbon brushes is carbon, which is easy to wear, so motors, generators or other rotating machinery using carbon brushes should be regularly maintained and replaced, and carbon deposits should be cleaned. Because there are a large number of motors, generators or other rotating machinery that use carbon brushes in the industry, the number of carbon brushes required when the equipment leaves...

AI Technical Summary

Problems solved by technology

[0004] Carbon brushes are usually pressed by a press molding machine. The existing carbon brush production equipment has the problem of low production efficiency, and the existing graphite carbon brush molding machine feeding device, due to the different quality of various components in the mixed raw materials, the raw materials The components in it will be mixed unevenly, which will lead to the poor uniformity of the final pressed carbon brush, the problem of low product quality, and the performance of the carbon brush to transmit energy or signal will be deteriorated
