Rotary quantitative taking out device

Abstract

The invention discloses a rotary quantitative taking device, which comprises a storage tank, a measuring bucket and an elastic mounting part. The storage tank has a tank cavity and a mating surface at the bottom thereof, and the tank cavity is divided into phases and partitioned by a partition plate. The powder inlet chamber and the powder outlet chamber, the measuring bucket is pressed against the fitting surface by the elastic force of the mounting part and can rotate around the axis of rotation against the fitting surface, the measuring bucket has at least one Circle quantitative groove, each circle quantitative groove includes at least two mutually isolated quantitative grooves, the measuring bucket has at least two working positions on its rotation track, and at least one quantitative groove communicates with the powder inlet chamber in each working position. At least another quantitative groove communicates with the powder outlet chamber. Through the elastic mounting parts, the measuring bucket is always pressed against the mating surface of the storage tank with proper elastic force, which can effectively reduce the movement gap between the measuring bucket and the storage tank and make the measuring bucket move smooth.

Description

technical field [0001] The invention relates to a quantitative taking device for taking fluid substances such as powder or granules. 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 ...

[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 Gap, causing the slide to leak powder during movement; 3. If the size of the movement space is uneven or the size of the slide is uneven, the first two situations will occur

[0004] All in all, the current fixed structure has very high requirements on the machining accuracy and assembly accuracy of the sliding bucket and sliding sleeve. Improper precision matching will cause the function to be unrealized

Therefore, in every link of mold, parts production and assembly, a certain dimensional accuracy must be met, and the dimensional accuracy is at the same level as the size of the powder used. According to the current technology and production process, it is impossible to mass-produce manufacture
