Intermittent particulate material feeding device

Abstract

The invention relates to an intermittent particulate material feeding device, which comprises a turntable containing cup feeding mechanism, an incomplete gear, a parallel indexing cam, a rotary working platform, a connecting shaft and the like. The intermittent particulate material feeding device is characterized in that the incomplete gear is fixedly connected with a driving wheel of the parallel indexing cam by the same shaft (a driving shaft), a driven wheel of the incomplete gear is fixedly connected with an upper turntable of the turntable containing cup feeding mechanism by the same shaft, and a driven wheel of the parallel indexing cam is fixedly connected with the rotary working platform by the same shaft so that a machine can make the turntable containing cup feeding mechanism and the rotary working platform achieve synchronous intermittent rotation in the running process. When the intermittent particulate material feeding device works, materials fall into a material containing chamber from a hopper; the upper turntable dials the materials into a containing cup by a scratch board and scratches overflow parts in the rotating process; and when the containing cup filled with the materials rotates to a discharging station along with the upper turntable, the particulate materials fall down along a sliding cylinder to finish the feeding process. The intermittent particulate material feeding device has a simple structure, a low price and high production efficiency, can ensure the volume of the used particulate materials, and can automatically feed a rotary intermittent four-station powder pressure forming machine.

Description

technical field [0001] The invention relates to a powder and granular material feeding device, in particular to an intermittent powder and granular material feeding device. Background technique [0002] The workpiece made of powder die-casting has simple manufacturing process and low cost; therefore, powder pressure molding machine is widely used in mechanical processing. The pressure forming machine is used to achieve the purpose of forming by pressure processing of powder materials, and can realize automatic discharge for the completion of follow-up work. In order to improve efficiency, a rotary table is adopted, which has two working stages of movement and rest. In the rest stage, each station completes its own processing action; in the rotary stage, the worktable moves to the next station. [0003] However, most of the existing powder and granular feeding devices cannot meet the intermittent rotation of the workbench synchronously, so that the expected requirements of ...

Problems solved by technology

[0003] However, most of the existing powder and granular feeding devices cannot meet the intermittent rotation of the workbench synchronously, so that the expected requirements of product processing cannot be completed, and the production efficiency is low; in addition, there are a few powder and granular material feeding devices that can meet the intermittent rotation of the worktable It can supply materials for it, but its structure is complex and expensive, and the volume guarantee of the powder used is not very accurate
