Description

An automatic batching device for solid powder materials Technical Field

[0001] This application relates to the field of chemical experimental auxiliary devices, and in particular to an automatic batching device for solid powder materials. Background Technology

[0002] In chemical experiments, especially those requiring extremely high reaction precision, solid-liquid mixing systems play a crucial role. In particular, the quality of solid powder preparation and the precision of mixing directly affect the reliability and repeatability of experimental results. Currently, solid powder mixing is typically done manually using tools such as measuring spoons, but manual mixing often fails to achieve the required high precision standards.

[0003] At the same time, 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 brand-new silo 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 this application is to provide an automatic batching device for solid powder materials, which aims to solve or improve at least one of the above-mentioned technical problems.

[0006] To achieve the above objectives, this application provides the following solution: This application provides an automatic batching device for solid powder materials, comprising:

[0007] The silo body has a drive silo and a material silo arranged sequentially from top to bottom, and the material silo has a discharge port at the bottom.

[0008] An elastic reset mechanism is slidably and rotatably disposed within the drive compartment;

[0009] A powder feeding rod is fixedly connected to the elastic reset mechanism. The powder feeding rod extends into the material bin and protrudes through the discharge port. A material trough is provided on the side wall of the powder feeding rod.

[0010] A stirring component is located inside the material silo, and the stirring component is connected to the elastic reset mechanism;

[0011] The material cylinder is detachably connected to the silo body, and the material cylinder is in communication with the material silo.

[0012] Optionally, the elastic reset mechanism includes:

[0013] A rotating seat is rotatably connected within the drive housing via bearings;

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

[0015] An elastic element is disposed between the slider and the rotating seat.

[0016] Optionally, the inner wall of the rotating seat is provided with multiple sliding grooves, and a connecting block is slidably fitted in the sliding groove, and the connecting block is fixedly connected to the slider.

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

[0018] Optionally, the stirring component includes a sleeve and spiral blades disposed on the outer wall of the sleeve, the sleeve being fixedly connected to the rotating seat, and the sleeve being sleeved outside the powder feeding rod.

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

[0020] Optionally, the feed trough is spiral-shaped.

[0021] Optionally, the elastic element is a helical spring.

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

[0023] Optionally, one end of the compartment is provided with a downward-facing slot.

[0024] This application discloses the following technical effects: Solid powder material in the material cylinder flows into the material hopper, allowing the material trough on the side wall of the powder feeding rod to carry a fixed amount of material. The downward movement of the elastic reset mechanism causes the material trough of the powder feeding rod to extend out of the discharge port, allowing the material in the trough to be automatically discharged from the hopper. Furthermore, the elastic reset mechanism rotates while sliding down, causing the stirring component to rotate synchronously. This not only allows the material in the material hopper to move downward but also prevents the material from clumping. Through repeated reciprocating operations of the powder feeding rod's extension and retraction and the rotation of the stirring component, precise quantitative solid powder material batching is achieved, improving the quality of solid powder material preparation.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Referring to Figures 1-4, this application provides an automatic batching device for solid powder materials, comprising:

[0034] The silo body 1 has a drive silo and a material silo arranged sequentially from top to bottom, and the material silo has a discharge port 2 at the bottom.

[0035] The flexible reset mechanism is slidably and rotatably installed in the drive compartment;

[0036] The powder feeding rod 3 is fixedly connected to the elastic reset mechanism. The powder feeding rod 3 extends into the material bin and protrudes through the discharge port 2. A material trough 4 is provided on the side wall of the powder feeding rod 3.

[0037] The agitator is located inside the material silo and is connected to the elastic reset mechanism.

[0038] Material cylinder 5 is detachably connected to silo body 1, and material cylinder 5 is connected to material silo.

[0039] Solid powder material in material cylinder 5 flows into material hopper, allowing the material trough 4 on the side wall of powder feeding rod 3 to carry a fixed amount of material. The downward movement of the elastic reset mechanism causes the material trough 4 of powder feeding rod 3 to extend out of discharge port 2, allowing the material in the material trough 4 to be automatically discharged from hopper 1. The elastic reset mechanism rotates while sliding down, causing the stirring component to rotate synchronously. This not only allows the material in the material hopper to move downward but also prevents the material from clumping. Through repeated reciprocating operations of the extension and retraction of powder feeding rod 3 and rotation of stirring component, precise quantitative solid powder material batching is achieved, improving the quality of solid powder material preparation.

[0040] In one embodiment of this application, the 13 elastic reset mechanism includes:

[0041] Rotary seat 6 is rotatably connected to the drive compartment via bearings;

[0042] The slider 7 is slidably connected inside the rotating seat 6, and the slider 7 is fixedly connected to the powder feeding rod 3;

[0043] The elastic element 8 is disposed between the slider 7 and the rotating seat 6.

[0044] The slider 7 slides along the rotating seat 6 and cooperates with the elastic element 8, which can realize the extension and retraction operation of the powder feeding rod 3. The rotation of the rotating seat 6 can realize the rotation operation of the stirring element.

[0045] In one embodiment of this application, a plurality of sliding grooves 9 are provided on the inner sidewall of the rotating seat 6, and a connecting block 10 is slidably fitted in the sliding groove 9, and the connecting block 10 is fixedly connected to the slider 7.

[0046] By setting a sliding groove 9 and a connecting block 10 that slides with the sliding groove 9, when the slider 7 rotates, the connecting block 10 can drive the rotating seat 6 to rotate synchronously. When the slider 7 slides, the connecting block 10 slides in the sliding groove 9, so that only the slider 7 needs to be driven to achieve the effect of driving the powder feeding rod 3 to extend and retract and driving the stirring component to rotate.

[0047] In one embodiment of this application, a cross-shaped slot 11 is provided at the top of the slider 7.

[0048] The cross slot 11 facilitates compatibility with external drive devices, such as existing devices like retractable, self-rotating robotic arm structures with cross slots.

[0049] In one embodiment of this application, the stirring component includes a sleeve 12 and a spiral blade 13 disposed on the outer wall of the sleeve 12. The sleeve 12 is fixedly connected to the rotating seat 6 and is sleeved on the outside of the powder feeding rod 3.

[0050] In one embodiment of this application, a feed pipe 14 communicating with the material bin is fixedly connected to the side wall of the bin 1. The feed pipe 14 is detachably connected to the material cylinder 5 by a thread. The threaded connection facilitates the disassembly and replacement of the material cylinder 5.

[0051] In one embodiment of this application, the feed trough 4 is spiral-shaped, which facilitates the automatic discharge of solid powder material from the feed trough 4.

[0052] In one embodiment of this application, the elastic element 8 is a helical spring, which requires no lubrication, has strong anti-fouling properties, and occupies little longitudinal space.

[0053] In one embodiment of this application, a magnet 15 is fixedly connected to one end of the housing 1 to facilitate cooperation with an external gripping device, such as a multi-axis moving device with magnetic blocks or electromagnets.

[0054] In one embodiment of this application, one end of the compartment 1 is provided with a downward-facing slot 16, which facilitates insertion and fixing onto an external frame with an adapter block.

[0055] All components of the hopper 1 in this application are manufactured by 3D printing (applicable to but not limited to FDM process), so the manufacturing cost is very low. It can be used as a disposable consumable, eliminating the need for cleaning. It has the effects of corrosion resistance and wear resistance, and can maintain long-term stability and reliability.
