Description

Technical Field

[0001] The present invention relates to the technical field of chemical experiment auxiliary devices, and particularly to an automatic batching device for solid powder materials. Background Art

[0002] In chemical experiments, especially those with extremely high requirements for reaction precision, the solid-liquid batching system plays a crucial role. In particular, the preparation quality and batching precision of solid powder materials directly affect the reliability and repeatability of experimental results. The existing batching of solid powder materials is usually manually carried out using tools such as measuring spoons, and manual batching often fails to meet the required high-precision standards.

[0003] At the same time, the existing automatic batching systems on the market have poor versatility and cannot adapt to the characteristics of various powder materials. Therefore, it is necessary to develop a new hopper and feeding system.

[0004] Therefore, there is an urgent need for an automatic batching device for solid powder materials. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic batching device for solid powder materials, aiming to solve or improve at least one of the above technical problems.

[0006] To achieve the above purpose, the present invention provides the following solution: The present invention provides an automatic batching device for solid powder materials, including:

[0007] A hopper body, which is provided with a driving chamber and a material chamber from top to bottom in sequence, and a discharge port is arranged at the bottom end of the material chamber;

[0008] An elastic reset mechanism, which is slidably and rotatably arranged in the driving chamber;

[0009] A powder feeding rod, which is fixedly connected to the elastic reset mechanism, extends into the material chamber and protrudes through the discharge port, and a material groove is arranged on the side wall of the powder feeding rod;

[0010] A stirring member, which is located in the material chamber and is connected to the elastic reset mechanism;

[0011] A material cylinder, which is detachably connected to the hopper body and is communicated with the material chamber.

[0012] Optionally, the elastic reset mechanism includes:

[0013] A rotating seat, which is rotatably connected in the driving chamber through a bearing;

[0014] A slider, which is slidably connected in the rotating seat, and the slider is fixedly connected to the powder feeding rod;

[0015] An elastic member is provided between the slider and the rotating seat.

[0016] Optionally, a plurality of sliding grooves are formed in the inner side wall of the rotating seat, and a connecting block is slidably engaged in the sliding groove, and the connecting block is fixedly connected to the slider.

[0017] Optionally, a cross-shaped slot is formed at the top of the slider.

[0018] Optionally, the stirring member includes a sleeve and spiral blades provided on the outer side wall of the sleeve. The sleeve is fixedly connected to the rotating seat, and the sleeve is sleeved outside the powder feeding rod.

[0019] Optionally, a material guiding pipe communicating with the material bin is fixedly connected to the side wall of the bin body, and the material guiding pipe is detachably connected to the material cylinder by a thread.

[0020] Optionally, the material groove is spiral.

[0021] Optionally, the elastic member is a spiral spring.

[0022] Optionally, a magnet is fixedly connected to one end of the bin body.

[0023] Optionally, a card slot with an opening facing downward is formed at one end of the bin body.

[0024] The present invention discloses the following technical effects: The solid powder material in the material cylinder flows into the material bin, so that the material groove on the side wall of the powder feeding rod can carry a fixed amount of material. The downward movement of the elastic reset mechanism drives the material groove of the powder feeding rod to extend out of the discharge port, so that the material in the material groove can be automatically discharged from the bin body, and the elastic reset mechanism rotates while moving downward, driving the stirring member to rotate synchronously. This not only enables the material in the material bin to move downward, but also avoids material caking. By repeatedly operating the powder feeding rod to expand and contract and the stirring member to rotate, accurate quantitative solid powder material batching operation is achieved, improving the quality of solid powder material preparation.

[0039] The solid powder material in the material cylinder 5 flows into the material bin, so that the feed trough 4 on the side wall of the powder feeding rod 3 can carry a fixed amount of material.
