Quantitative dispenser for powder

Abstract

This quantitative powder fetching device comprises of a sliding sleeve with an inside powder inlet groove through it, a sliding hopper with a quantitative groove inside it and pressed by the elastic components to the sliding sleeve to form a siding pair or rotating pair and elastic components, and when the quantitative groove of the sliding hopper connects with the powder inlet groove of the sliding sleeve to let the powder it, a No.1 position of the sliding hopper's moving path is fixed and when the quantitative groove of the sliding hopper separates with the powder inlet groove of the sliding sleeve to discharge the powder, it comes with the No.2 position. Pressing the sliding hopper on the sliding sleeve with proper elastic force, it can not only effectively reduce the gap between them but also maintain the smooth moving of the sliding hopper, so as to make it work and reduce the precision requirement for manufacturing and assembly.

Description

technical field [0001] The invention relates to a powder quantitative taking device. Background technique [0002] The existing powder taking devices are composed of a sliding sleeve and a sliding bucket. The sliding bucket is installed on the sliding sleeve and can slide or rotate relative to the sliding sleeve. pink. [0003] There is a common problem in the existing devices: the sliding bucket is assembled in the fixed space formed by the sliding sleeve to move (including sliding and rotating), or the sliding bucket is fixedly assembled on the rotating shaft to rotate. This kind of fixed structure causes the following disadvantages: 1. If the movement space is too small or the slide is fixed too tightly, it will hinder the movement of the slide and fail to meet the functional requirements; 2. If the movement space is too large or the slide is fixed too loosely, a large 3. If the size of the movement space is uneven or the size of the slide is uneven, the first two situa...
