Technical Field
[0001] This utility model relates to the field of automatic powder material dispensing, and in particular to an automatic powder material dispensing device. Background Technology
[0002] Powder materials refer to aggregates of metallic or non-metallic particles with a size of less than 1 mm. They are widely used in 3D printing, injection molding, aerospace, and other fields. Classified by composition, metal powders include titanium alloys, stainless steel, and nickel-based corrosion-resistant alloys, used for additive manufacturing and surface strengthening; precious metal powders, such as silver and palladium powders, are used in electronic pastes and catalysts; ceramic and composite powders, such as alumina and silicon carbide, are used in wear-resistant coatings. Classified by particle size, they include conventional powders, ultrafine powders, and nanoparticles. Automatic batching devices refer to computer-controlled, integrated mechanical conveying, intelligent metering, and mixing systems that can dynamically weigh, proportion, and mix multiple raw materials according to a preset formula, ultimately outputting homogeneous materials. In the use of existing automatic powder material batching devices, the metering operation is complicated and it is impossible to distinguish unsuitable powder particles, which affects the batching. Therefore, those skilled in the art provide an automatic powder material batching device to solve the problems mentioned in the background art. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic powder material batching device. This device uses a weighing instrument in conjunction with a computer to set a weighing threshold. Only when the designed weight is reached will the first electric gate close, and at the same time, the second electric gate will open to perform the batching operation. This makes the measurement more convenient and also adds a vibrating motor and a screen to prevent the powder material from clumping in the air and affecting the batching.
[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic powder material dispensing device, comprising a dispensing bucket and four assembly frames, wherein the four assembly frames are arranged in a ring and fixedly connected to the upper end face of the dispensing bucket, and protruding blocks are provided on both sides of the lower end face of the four assembly frames near the center of the dispensing bucket, and a powder metering device is provided between the end faces of the two protruding blocks of the four assembly frames that are close to each other. The four powder metering devices include four metering barrels. Each of the four metering barrels has a weighing device fixedly connected to the upper end of its lower inner wall. Each of the four weighing devices has a ramp fixedly connected to its upper end. Each of the four metering barrels has a second electric gate on the lower side of its end face near the center of the mixing barrel. Each of the four metering barrels has a moving groove inside its upper end. The upper end face of each of the four second electric gates passes through the lower end face of the moving groove and extends into it. Each of the four moving grooves has multiple second electric telescopic rods. The upper end faces of the multiple second electric telescopic rods are fixedly connected to the upper inner wall of each of the four metering barrels, and the output ends of the multiple second electric telescopic rods are fixedly connected to the upper end faces of the four second electric gates. With the above technical solution, when the required powder material falls onto the ramp plate, the weighing device located at the lower end of the ramp plate begins to weigh the powder material. When a certain weight is reached, the weighing device sends a signal to the PLC controller. After receiving the signal, the PLC controller closes the first electric gate and simultaneously opens the second electric gate by controlling the retraction of the second electric telescopic rod in the moving slot. The PLC controller sets one second electric telescopic rod as the main control drive and the others as auxiliary control drives. By controlling the main control drive to drive the auxiliary control drives to retract, it is a common technical means in existing electric telescopic rod synchronous control systems, which will not be elaborated on here. Then the powder material enters the batching tank through the ramp plate for batching.
[0005] Furthermore, each of the four powder metering devices is fixedly connected to a powder conveying device at its upper end. Each of the four powder conveying devices includes a base. Each of the four bases has a sliding groove with a certain slope at the center of its upper surface. Each of the four sliding grooves has a push plate at its upper end. Each of the four push plates has a first electric telescopic rod fixedly connected to its end face away from the center of the mixing barrel. The lower end face of the fixed end of each of the four first electric telescopic rods is fixedly connected to the upper surface of the four sliding grooves away from the center of the mixing barrel. Each of the four first electric telescopic rods has a powder inlet at its upper surface near the center of the mixing barrel. The lower end face of each of the four powder inlets passes through the upper surface of the four bases and extends into their interiors. Each of the four powder inlets has a first electric gate rotatably connected to its inner sidewall. Each of the four bases has a cover plate fixedly connected to its upper end. Each of the four cover plates has a hole at its center. The above technical solution involves first placing the powder to be prepared into different raw material tanks sequentially during powder preparation. Then, four PLC controllers control four first electric telescopic rods to push four push plates. When the four first electric telescopic rods reach the front end of the sliding groove and touch the base, they begin to retract. One electric telescopic rod is designated as the main control drive, and the others as auxiliary control drives. The main drive drives the auxiliary drives for extension and retraction, a common technique in existing electric telescopic rod synchronous control systems, which will not be elaborated upon here. When the rear end of the four sliding grooves retracts and touches the signal baffle, a signal is sent to the PLC controller. A threshold is set for the signal; upon reaching the threshold, the PLC controller controls the first electric telescopic rods to reverse or stop. This is also a common technique in existing control systems, which will not be elaborated upon here. The rods then stop extending and are fixed. After receiving the signal, the PLC controller controls the raw material tanks to begin conveying material through the conveying hopper and conveying pipe. Simultaneously, the PLC controller controls the first electric telescopic rods to extend and retract, pushing the push plates to push the powder into the powder inlet, which then falls into the powder metering device through the opened first electric gate.
[0006] Furthermore, each of the four metering barrels has a push-pull block at the upper end of the second electric gate on the end face near the center of the mixing barrel. The end faces of the four push-pull blocks away from the center of the mixing barrel all penetrate the four metering barrels and extend into the metering barrel. Each of the four push-pull blocks has a vibration motor inside the end face away from the center of the mixing barrel. Each of the four vibration motors has a screen fixedly connected to its output end. Through the above technical solution, as the powder continuously enters the powder metering device, a screen will screen and isolate the powder material with a larger particle size. At the same time, in order to prevent large particles from clogging the screen, the vibration motor connected to the screen will start to vibrate synchronously when the PLC controller controls the movement of the first electric telescopic rod, so as to further drop the powder material of the required particle size onto the inclined plate.
[0007] Furthermore, a PLC controller is fixedly connected to one side wall of one of the four assembly racks; The above technical solutions facilitate the control of various electronic devices.
[0008] Furthermore, all four push-pull blocks are fitted with shock-absorbing plates on their outer sides; The above technical solution prevents the push-pull block, which is fixedly connected to the vibration motor, from affecting the operation of the equipment during vibration.
[0009] Furthermore, signal baffles are fixedly connected to both sides of the upper end face of the four sliding grooves away from the center of the mixing barrel; The above technical solution facilitates the control of the first electric telescopic rod by the PLC controller.
[0010] This utility model has the following beneficial effects: In this invention, the automatic powder material batching device uses a weighing instrument and a computer to set the weighing value. Only when the design value is reached will the first electric gate close and the second electric gate open, allowing the batching operation to proceed. This reduces the use of measuring tools, making measurement simpler, faster, and more accurate.
[0011] In this invention, the automatic powder material batching device adds a vibrating motor and a screen to prevent large powder particles from entering the batching hopper and affecting the batching process. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Reference Figure 1-4An embodiment of this utility model provides an automatic powder material dispensing device, including a dispensing tank 1 and four assembly racks 3. The four assembly racks 3 are arranged in a ring and fixedly connected to the upper end face of the dispensing tank 1. Protruding blocks 9 are provided on both sides of the lower end face of the four assembly racks 3 near the center of the dispensing tank 1. A powder metering device 8 is provided between the end faces of the two protruding blocks 9 of the four assembly racks 3 that are close to each other.
[0016] The four powder metering devices 8 include four metering barrels 801. Each metering barrel 801 has a weighing device 803 fixedly connected to its upper inner wall. Each weighing device 803 has a ramp 802 fixedly connected to its upper end. Each metering barrel 801 has a second electric gate 804 located on its lower side near the center of the mixing barrel 1. Each metering barrel 801 has a moving groove 810 located inside its upper end. The upper end of each second electric gate 804 extends through the lower end of the moving groove 810 into its interior. Each moving groove 810 contains multiple second electric telescopic rods 805. The upper ends of the multiple second electric telescopic rods 805 are fixedly connected to the upper inner wall of each of the four metering barrels 801, and their output ends are fixedly connected to the four second electric gates 802. 4. On the upper surface, when the required powder material falls onto the ramp plate 802, the weighing device 803 located at the lower end of the ramp plate 802 begins to weigh the powder material. When a certain weight is reached, the weighing device 803 sends a signal to the PLC controller 4. After receiving the signal, the PLC controller 4 closes the first electric gate 709 and simultaneously controls the second electric telescopic rod 805 in the moving slot 810 to retract and open the second electric gate 804. The PLC controller 4 sets one second electric telescopic rod 805 as the main control drive and the others as auxiliary control drives. By controlling the main control drive to drive the auxiliary control drives to retract, it is a common technical means in the existing electric telescopic rod synchronous control system, which will not be elaborated on here. Then the powder material enters the mixing tank 1 through the ramp plate 802 for mixing.
[0017] like Figure 1 , 2As shown in Figure 4, each of the four powder metering devices 8 is fixedly connected to a powder conveying device 7. Each powder conveying device 7 includes four bases 702. A sliding groove 706 with a certain slope is provided at the center of the upper surface of each of the four bases 702. A push plate 704 is provided at the upper end of each of the four sliding grooves 706. A first electric telescopic rod 701 is fixedly connected to the end face of each push plate 704 away from the center of the mixing tank 1. The lower end face of the fixed end of each of the four first electric telescopic rods 701 is respectively fixedly connected to the upper surface of the four sliding grooves 706 away from the center of the mixing tank 1. Each telescopic rod 701 has a powder inlet 703 located near the center of the mixing tank 1 on its upper surface. The lower surfaces of the four powder inlets 703 penetrate the upper surfaces of the four bases 702 and extend into them. A first electric gate 709 is rotatably connected to the inner wall of each of the four powder inlets 703. A cover plate 708 is fixedly connected to the upper end of each of the four bases 702. Each of the four cover plates 708 has a hole 705 at its center. During powder preparation, the powder to be prepared is first placed into different raw material tanks 2 sequentially, and then the four first electric gates 709 are controlled by four PLC controllers 4. The electric telescopic rod 701 pushes the four push plates 704 to start moving. When the four first electric telescopic rods 701 move to the front end of the sliding groove 706 and touch the base 702, the four first electric telescopic rods 701 begin to retract. By setting one electric telescopic rod as the main control drive and the others as auxiliary control drives, the main drive drives the auxiliary drives to extend and retract. This is a common technical means in existing electric telescopic rod synchronous control systems, which will not be elaborated on here. When the rear end face of the four sliding grooves 706 retracts and touches the signal baffle 707, a signal is sent to the PLC controller 4. A threshold is set for the signal. When the threshold is reached, the PLC controller 4 controls the first electric telescopic rod 701 to reverse or stop. This is a common technique in existing control systems and will not be elaborated on here. Then, the extension is stopped and fixed. After receiving the signal, the PLC controller 4 controls the raw material tank 2 to start conveying material through the conveying bucket 5 and the conveying pipe 6. At the same time, the PLC controller 4 controls the first electric telescopic rod 701 to start extending and retracting, pushing the push plate 704 to push the powder material into the powder material inlet 703 and further into the powder metering device 8 through the opened first electric gate 709.
[0018] like Figure 1 , 2As shown in Figure 3, each of the four metering barrels 801 has a push-pull block 806 at the upper end of the second electric gate 804 on the end face near the center of the mixing barrel 1. The end faces of the four push-pull blocks 806 away from the center of the mixing barrel 1 all pass through the four metering barrels 801 and extend into the interior of the metering barrel 801. Each of the four push-pull blocks 806 has a vibration motor 807 installed inside the end face away from the center of the mixing barrel 1. Each of the four vibration motors 807 has a screen 809 fixedly connected to its output end. As the powder continuously enters the powder metering device 8, the screen 809 will screen and isolate the powder material with a larger particle size. At the same time, in order to prevent large particles from clogging the screen 809, the vibration motor 807 connected to the screen 809 will start to vibrate synchronously when the first electric telescopic rod 701 is controlled by the PLC controller 4, so that the powder material of the required particle size falls further onto the inclined plate 802.
[0019] like Figure 1 and 2 As shown, one of the four assembly racks 3 has a PLC controller 4 fixedly connected to one side wall of the assembly rack 3, which facilitates the control of various electronic devices.
[0020] like Figure 2 and 3 As shown, damping plates 808 are fitted on the outer sides of the four push-pull blocks 806 to prevent the push-pull blocks 806, which are fixedly connected to the vibration motor 807, from affecting the operation of the equipment during vibration.
[0021] like Figure 1 and 4 As shown, signal baffles 707 are fixedly connected to both sides of the upper end face of the four sliding grooves 706 away from the center of the mixing tank 1, so as to facilitate the control of the first electric telescopic rod 701 by the PLC controller 4.
[0022] Working principle: When preparing powder, the powder to be prepared is first placed into different raw material tanks 2 in sequence. Then, four PLC controllers 4 control four first electric telescopic rods 701 to push four push plates 704 to start moving. When the four first electric telescopic rods 701 move to the front end of the sliding groove 706 and touch the base 702, the four first electric telescopic rods 701 begin to retract. By setting one electric telescopic rod as the main control drive and the others as auxiliary control drives, the main drive drives the auxiliary drives to extend and retract. This is a common technical means in existing electric telescopic rod synchronous control systems, which will not be elaborated on here. When the four sliding grooves 706... When the rear end retracts and touches the signal baffle 707, it sends a signal to the PLC controller 4. A threshold is set for the signal. After the threshold is reached, the PLC controller 4 controls the first electric telescopic rod 701 to reverse or stop. This is a common technical means in existing control systems and will not be elaborated on here. Then, it stops extending and is fixed. After receiving the signal, the PLC controller 4 controls the raw material tank 2 to start conveying material through the conveying bucket 5 and the conveying pipe 6. At the same time, the PLC controller 4 controls the first electric telescopic rod 701 to start extending and retracting, pushing the push plate 704 to push the powder material into the powder material inlet 703 and further into the powder metering device 8 through the opened first electric gate 709.
[0023] As powder continuously enters the powder metering device 8, a screen 809 separates and isolates larger powder particles. To prevent large particles from clogging the screen 809, a vibrating motor 807 connected to the screen 809 starts vibrating synchronously when the first electric telescopic rod 701 is moved by the PLC controller 4. This allows the powder of the desired particle size to fall onto the ramp 802. To prevent the push-pull block 806, which is fixedly connected to the vibrating motor 807, from affecting equipment operation during vibration, damping plates 808 are fitted on the outside of each push-pull block 806. When the desired powder falls onto the ramp 802, the weighing device 803 located at the lower end of the ramp 802... The powder material is weighed. When a certain weight is reached, the weighing device 803 sends a signal to the PLC controller 4. After receiving the signal, the PLC controller 4 closes the first electric gate 709 and simultaneously controls the second electric telescopic rod 805 in the moving slot 810 to retract and open the second electric gate 804. The PLC controller 4 sets one second electric telescopic rod 805 as the main control drive and the others as auxiliary control drives. The main control drive drives the auxiliary control drives to retract. This is a common technique in existing electric telescopic rod synchronous control systems and will not be elaborated on here. Then, the powder material enters the batching tank 1 through the ramp 802 for batching.
[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
