Description

Technical Field

[0001] The utility model relates to the technical field of automatic proportioning and stirring of metal powder, and more specifically to an automatic proportioning and stirring device for metal powder. Background Art

[0002] Metal powder refers to a group of metal particles with a size of less than 1mm, including single metal powder, alloy powder and certain refractory compound powders with metallic properties. It is the main raw material for powder metallurgy. In the production of some alloy metals, it is necessary to mix and stir the metal powders of each component in proportion in advance. At this time, an automatic proportioning and stirring device for metal powder is needed.

[0003] A search of the Chinese utility model with application number "202220215472.9" discloses an automated proportioning and stirring device for batching metal powders, the automated proportioning and stirring device for batching metal powders comprising: a base and a fixed plate fixedly mounted on the base, a horizontal plate arranged parallel to the base being fixed on the fixed plate; a mixing barrel is also fixedly mounted on the base, a stirring assembly for stirring the material in the mixing barrel is arranged on the horizontal plate; an inclined plate with circular holes is fixed on the mixing barrel, and a limit plate equidistantly arranged in a circle is also arranged on the base, the limit plate is connected to a feeding mechanism for driving the limit plate to move, and the feeding mechanism is arranged on the base; a driving mechanism connected to the feeding mechanism is also arranged on the base, and the driving mechanism drives the limit plate to move through the feeding mechanism.

[0004] The reference document uses a rotating rod to drive the material barrel to rotate, and the main material is added in sequence to achieve the effect of automatic feeding, which will cause the feeding to take a long time, thus seriously affecting the work efficiency, and will also cause the single metal powder to be layered and piled up in the mixing barrel, which is not conducive to the subsequent mixing and stirring of each metal powder raw material, and will prolong the mixing and stirring time, thereby also causing the work efficiency of the metal powder proportioning and stirring. In view of this, we propose an automatic proportioning and stirring device for metal powder. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, meet practical needs, and provide an automatic proportioning and stirring device for metal powders to solve the technical problem of low working efficiency of the current automatic proportioning and stirring device for metal powders.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: an automatic proportioning and stirring device for metal powder, comprising a bracket, a box body is arranged on the top of the bracket, a plurality of groups of metering barrels are arranged equidistantly around the top of the box body, a stirring tank is arranged inside the bracket below the box body, and an output end at the bottom of the box body is connected to an output end at the top of the stirring tank through a conduit;

[0007] A motor is arranged at the center of the top of the box body, and a mounting plate is arranged symmetrically inside the box body, and a rotating shaft at the output end of the motor is connected to the center of the top of the mounting plate;

[0009] The utility model adopts a designed box body, the bottom of the box body is a funnel cover, and the metering barrels are installed on the top of the box body. Therefore, when the metal powder raw materials in each metering barrel are added into the mixing tank, the metal powder raw materials in each metering barrel will be discharged in proportion and will directly fall into the box body, and then will be concentrated through the funnel cover to achieve a certain degree of pre-mixing effect. The mixed raw materials enter the mixing tank at one time through the conduit, so that the filling of the raw materials can be completed at one time, which can save time and improve work efficiency. The raw materials that fall into the mixing tank are mixed without stratification and accumulation, which saves stirring and mixing time and can also greatly improve the metal powder. To improve the mixing efficiency, the raw materials discharged from the metering barrel will fall onto the mounting plate, and then the motor drives the mounting plate to rotate. The centrifugal force generated during the rotation of the mounting plate will centrifugally disperse the raw materials, and then fall into the box body, and finally be discharged into the mixing tank. This method can greatly improve the pre-mixing effect of each raw material, and can further reduce the mixing time of the raw materials in the mixing tank, thereby further improving the working efficiency of the device. When the raw materials fall onto the inclined surface of the mounting plate, the raw materials will have a sliding force, and then in the process of centrifugal rotation of the mounting plate, the raw materials will fall in a spiral form, so that the raw materials can fall into the box body quickly and efficiently, thereby improving the efficiency of raw material transportation and the working efficiency of the device.

[0017] 1. The utility model adopts a designed box body, the bottom of which is a funnel cover, and the metering barrels are installed on the top of the box body. Therefore, when the metal powder raw materials in each metering barrel are added into the mixing tank, the metal powder raw materials in each metering barrel will be discharged in proportion and will directly fall into the box body, and then be concentrated through the funnel cover to achieve a certain degree of pre-mixing effect. The mixed raw materials enter the mixing tank at one time through the conduit, so that the filling of the raw materials can be completed at one time, which can save time and improve work efficiency. The raw materials falling into the mixing tank are mixed without stratification and accumulation, which saves mixing and stirring time, and can also greatly improve the efficiency of metal powder mixing, thereby solving the technical problem of low working efficiency of the current automatic proportioning and stirring device for metal powder. Therefore, the utility model has the advantage of high work efficiency.

[0018] 2. The utility model also arranges a motor and a mounting plate on the box body. The raw materials discharged from the metering barrel will fall onto the mounting plate, and then the motor drives the mounting plate to rotate. The centrifugal force generated during the rotation of the mounting plate will centrifugally disperse the raw materials, and then fall into the box body, and finally be discharged into the mixing tank. This method can greatly improve the pre-mixing effect of each raw material, and can further reduce the mixing time of the raw materials in the mixing tank, thereby further improving the working efficiency of the device.

[0019] 3. The mounting plate in the utility model is in the shape of a truncated cone, with the large end surface at the bottom and the small end surface at the top, and the inclined surface around the mounting plate corresponds to the metering barrel. Therefore, when the raw material falls onto the inclined surface of the mounting plate, the raw material will have a downward force, and then during the centrifugal rotation of the mounting plate, the raw material will fall in a spiral form, so that the raw material can fall into the box body quickly and efficiently, thereby improving the efficiency of raw material transportation and improving the working efficiency of the device.

When the metal powder raw materials in each metering barrel 4 are added into the stirring tank 2, the metal powder raw materials in each metering barrel 4 will be discharged in proportion and will directly fall into the box body 3, and then will be concentrated through the funnel cover 303 to achieve a certain degree of pre-mixing effect, and the mixed raw materials will enter the stirring tank 2 at one time through the conduit, so that the filling of the raw materials can be completed at one time, which can save time and improve work efficiency, and the raw materials falling into the stirring tank 2 are mixed, and there will be no stratified accumulation, which saves stirring and mixing time and can also greatly improve the efficiency of metal powder mixing.

[0028] Specifically, the box body 3 includes a top plate 301, a middle circular cover 302 and a funnel cover 303. The top plate 301 is arranged on the top of the middle circular cover 302, and the funnel cover 303 is arranged on the bottom of the middle circular cover 302. The top plate 301 is convenient for the installation of each metering barrel 4, the middle circular cover 302 is convenient for the installation of the mounting plate 6, and the funnel cover 303 is convenient for the centralized discharge of each raw material, which has a certain pre-mixing effect.

[0029] Furthermore, a plurality of groups of weighing sensors 401 are equidistantly arranged around the bottom of the metering barrel 4, and the weighing sensors 401 are arranged on the top of the top plate 301, a top cover 402 is screwed on the top of the metering barrel 4, a discharge pipe 403 is arranged in the center of the bottom of the metering barrel 4, the discharge pipe 403 passes through the top plate 301, a welding block 404 is arranged on one side of the bottom end, and a motor 405 is arranged on the top of the welding block 404, and a bottom cover 406 is arranged on the output end of the motor 405 through a rotating shaft, the weighing sensor 401 is used to detect the discharge amount, and cooperate with an external controller to realize the proportional discharge of the raw materials, the top cover 402 is used to seal the top of the metering barrel 4, the motor 405 can drive the bottom cover 406 to rotate, when the bottom cover 406 is separated from the bottom of the discharge pipe 403, the raw materials are discharged normally, and when the bottom cover 406 covers the bottom of the discharge pipe 403, the raw materials cannot be discharged.

[0030] In an embodiment of the utility model, a motor 5 is arranged in the center of the top of the box body 3, and a mounting disk 6 is symmetrically arranged inside the box body 3. The rotating shaft at the output end of the motor 5 is connected to the center of the top of the mounting disk 6. The raw materials discharged from the metering barrel 4 will fall onto the mounting disk 6, and then the motor 5 drives the mounting disk 6 to rotate. The centrifugal force generated during the rotation of the mounting disk 6 will centrifugally disperse the raw materials, and then fall into the box body 3, and finally be discharged into the stirring tank 2. This method can greatly improve the pre-mixing effect of each raw material, and can further reduce the stirring and mixing time of the stirring tank 2 for the raw materials, thereby further improving the working efficiency of the device.

[0031] Specifically, the surface of the mounting plate 6 is arranged with anti-skid patterns, and a gap is reserved between the bottom of the mounting plate 6 and the inner wall of the middle circular cover 302. The raw materials can fall into the box body 3 through the gap. The anti-skid patterns increase the surface friction of the mounting plate 6, ensuring that the mounting plate 6 can exert centrifugal force on the raw materials when rotating, so that the raw materials can diffuse outward.

[0032] Furthermore, a plurality of connecting rods 601 are arranged around the mounting plate 6, and a ball 602 is arranged at one end of the connecting rod 601; a ball groove 304 is arranged on the inner wall of the middle circular cover 302, and the inner side of the ball groove 304 is an opening, and the ball 602 is located inside the ball groove 304.

When the raw material falls into the inclined surface of the mounting disk 6, the raw material will have a downward force, and then in the process of the mounting disk 6 rotating and centrifuging, the raw material returns to the form of spiral falling, so that the raw material can fall quickly and efficiently in the box body 3, thereby improving the efficiency of raw material transportation and improving the working efficiency of the device.

[0035] Working principle: This embodiment provides an automatic proportioning and stirring device for metal powder. First, when mixing the metal powder inside each metering barrel 4, the discharge ratio of each metering barrel 4 is set first, and then the metering barrel 4 is controlled to discharge the corresponding proportion of raw materials. The metal powder raw materials inside each metering barrel 4 will fall directly into the box body 3 after being discharged in proportion, and then be concentrated through the funnel cover 303 to achieve a certain degree of pre-mixing effect. The mixed raw materials enter the stirring tank 2 at one time through the conduit, so that the filling of the raw materials can be completed at one time, which can save time and improve work efficiency. The raw materials falling into the stirring tank 2 are mixed, and there will be no stratified accumulation, which saves stirring and mixing time and can also greatly improve the efficiency of metal powder mixing.

[0036] Secondly, the raw materials discharged from the metering barrel 4 will fall onto the mounting plate 6, and then the motor 5 drives the mounting plate 6 to rotate. The centrifugal force generated during the rotation of the mounting plate 6 will centrifugally disperse the raw materials, and then fall into the box body 3, and finally be discharged into the mixing tank 2. This method can greatly improve the pre-mixing effect of each raw material, and can further reduce the mixing time of the raw materials in the mixing tank 2, thereby further improving the working efficiency of the device;

[0037] Finally, when the raw material falls onto the inclined surface of the mounting plate 6, the raw material will have a downward force, and then during the centrifugal rotation of the mounting plate 6, the raw material will fall in a spiral form, so that the raw material can fall quickly and efficiently in the box body 3, thereby improving the efficiency of raw material transportation and improving the working efficiency of the device.
