Description

Technical Field

[0001] This utility model relates to the field of alloy powder processing technology, and more specifically, to an alloy powder feeding and weighing device. Background Technology

[0002] Alloy powders are widely used in various industrial fields, such as metal powder metallurgy, 3D printing material preparation, pharmaceuticals, and chemicals. They are used to manufacture high-performance parts, products with complex geometries, and special functional materials. Due to the unique physicochemical properties of alloy powders, their quality directly affects the performance and reliability of the final product. Therefore, precise control of the amount of alloy powder used in the production process is crucial.

[0003] Traditional methods of feeding alloy powder mainly rely on manual weighing using a balance or electronic scale. While this method is simple and direct, it suffers from inefficiency and large errors. Manual weighing requires individual weighing, which is time-consuming, especially when a large number of repetitive operations are needed. This not only increases labor costs but may also lead to a further decline in work efficiency due to factors such as fatigue. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an alloy powder feeding and weighing device.

[0005] An alloy powder feeding and weighing device includes a fixed frame, an electronic scale, a display screen, a loading frame, a feeding pipe, a conveying assembly, a connecting pipe, a loading box, and a feed pipe. The electronic scale is connected to one side of the fixed frame, and the display screen and the loading frame are connected to the electronic scale. The feeding pipe is connected to the bottom of the loading frame. The conveying assembly is connected to the fixed frame, the connecting pipe is connected to the conveying assembly, the loading box is connected to the connecting pipe, and the feed pipe is connected to the loading box.

The spiral tube is rotatably connected inside the guide cylinder, and the output shaft of the servo motor is fixedly connected to the spiral tube.

[0007] Optionally, the side of the guide cylinder closer to the loading frame is smaller than the side closer to the servo motor.

[0008] Optionally, it also includes a solenoid valve and a controller. The solenoid valve is connected to the feed pipe, and the controller is connected to the electronic scale. The solenoid valve, servo motor and display screen are all electrically connected to the controller.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0018] An alloy powder feeding and weighing device, such as Figures 1-4As shown, the system includes a fixed frame 1, an electronic scale 2, a display screen 3, a loading frame 4, a discharge pipe 5, a conveying assembly, a connecting pipe 12, a loading box 13, a feed pipe 14, a solenoid valve 6, a controller 7, a protective shell 11, and a heating element 15. The electronic scale 2 is fixedly connected to the right side of the fixed frame 1. The display screen 3 and the loading frame 4 are fixedly connected to the top of the electronic scale 2. The display screen 3 can display the reading of the electronic scale 2. The discharge pipe 5 is fixedly connected to the bottom of the loading frame 4. The conveying assembly is connected to the top of the fixed frame 1, and the connecting pipe 12 is connected to the conveying assembly. The top of the connecting pipe 12 is fixedly connected to the loading box 13, the top of the loading box 13 is fixedly connected to the feed pipe 14, the top of the discharge pipe 5 is fixedly connected to the solenoid valve 6, the top of the electronic scale 2 is fixedly connected to the controller 7, the solenoid valve 6, the servo motor 10 and the display screen 3 are all electrically connected to the controller 7, the top of the loading frame 4 is fixedly connected to the protective shell 11, the protective shell 11 can prevent the alloy powder from scattering and avoid the waste of alloy powder, the protective shell 11 is connected to the guide cylinder 8, and the heating pipe 15 is fixedly connected to the inside of the loading box 13 along the circumference.

[0019] like Figures 1-4 As shown, the conveying assembly includes a guide cylinder 8, a spiral tube 9, and a servo motor 10. The guide cylinder 8 is connected to the fixed frame 1. The right side of the guide cylinder 8 is located above the loading frame 4, and the servo motor 10 is installed on the left side of the guide cylinder 8. The right side of the guide cylinder 8 is open. The side of the guide cylinder 8 closer to the loading frame 4 is smaller than the side closer to the servo motor 10. The spiral tube 9 is rotatably connected inside the guide cylinder 8. The output shaft of the servo motor 10 is fixedly connected to the spiral tube 9.

[0020] Initially, solenoid valve 6 is closed. When feeding alloy powder, the mixed alloy powder is first poured into the loading box 13 through the feed pipe 14. The heating pipe 15 heats the alloy powder in the loading box 13 to dry it, preventing damp alloy powder from affecting the weighing accuracy. The alloy powder in the loading box 13 enters the guide cylinder 8 through the connecting pipe 12. The servo motor 10 drives the spiral tube 9 to rotate, so that the alloy powder is transported to the right side of the guide cylinder 8. The alloy powder falls into the loading frame 4, increasing the weight of the loading frame 4. The electronic scale 2 weighs the loading frame 4. When the weight of the alloy powder in the loading frame 4 reaches the feeding standard, the controller 7 shuts off the servo motor 10 and then opens the solenoid valve 6. The alloy powder flows along the feeding pipe 5. The alloy powder is dropped out, thus completing one feeding and weighing operation. When the alloy powder feeding is completed, the controller 7 closes the solenoid valve 6 and then turns on the servo motor 10 to continue driving the spiral tube 9 to rotate and transport the alloy powder. The above steps are repeated, thus eliminating the need for manual weighing and feeding of the alloy powder. Automated operation can significantly improve the feeding and weighing speed of this weighing device. The spiral tube 9 can continuously and stably transport the alloy powder, reducing intermediate downtime and greatly improving the working efficiency of this weighing device. Combined with the electronic scale 2 to monitor weight changes in real time, the working state of the servo motor 10 can be automatically adjusted according to the preset alloy powder weight, thereby achieving high-precision feeding control.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
