Description

Technical Field

[0001] This utility model relates to the field of material distribution technology, and in particular to a precise powder dispensing device. Background Technology

[0002] In numerous industries such as chemical, food, and pharmaceutical, powder batching is a crucial step in the production process, and its accuracy directly affects product quality and performance. Currently, most powder batching devices rely on manual weighing or simple mechanical assistance. Manual weighing is not only inefficient but also susceptible to operator bias and skill level, making it difficult to guarantee accuracy and consistency, easily leading to batching errors and affecting product quality stability. While simple mechanical aids, such as common volumetric batching devices, improve batching efficiency to some extent, their reliance on fixed volume measurement makes them unable to accurately adapt to the metering requirements of powders with different densities and flowability. When powder characteristics change, metering deviations are prone to occur. As industries increasingly demand more refined and standardized products, there is an urgent need for a batching device that can automate and precisely control the entire process from powder dispensing to weighing, addressing the problems of low accuracy, poor efficiency, and weak adaptability inherent in traditional batching methods.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Example 1

[0037] A precise powder dispensing device, such as Figure 1As shown, the device includes a discharge mechanism 4, a transfer mechanism 5, and a weighing mechanism. The transfer mechanism 5 is located between the discharge mechanism 4 and the weighing mechanism. The discharge mechanism 4 is equipped with a conveying pipe, a conveying shaft 42 is installed inside the conveying pipe, a spiral conveying blade 43 is installed on the conveying shaft 42, and a discharge port 44 is installed at the end of the conveying pipe. The weighing mechanism includes an outer hopper mechanism 1 and a tilting weighing mechanism 2. The tilting weighing mechanism 2 is partially installed inside the outer hopper mechanism 1. The top of the outer hopper mechanism 1 is equipped with a feed inlet 11, and the bottom of the outer hopper mechanism 1 is equipped with a discharge outlet 12. The transfer mechanism 5 is equipped with a conveyor belt, a partition plate 52 is installed on the conveyor belt, one end of the conveyor belt is located below the discharge port 44, and the other end of the conveyor belt is located above the feed inlet 11.

[0038] When the batching device is working, the discharge mechanism 4 pushes the powder along the conveying pipe to the discharge port 44 through the spiral conveying blades 43 on the conveying shaft 42, ensuring uniform output of the powder to reduce pipeline residue; the conveyor belt of the transfer mechanism 5 drives the partition plate 52 to segment and stably convey the powder falling from the discharge port 44 to the feed port 11 of the weighing mechanism. The partition plate 52 can prevent the powder from accumulating or scattering during the conveying process, reducing the residue in the conveying link; in the weighing mechanism, the tilting weighing mechanism 2 is partially placed inside the outer hopper mechanism 1. The powder falls into the tilting weighing mechanism 2 through the feed port 11 for weighing. After weighing, the tilting weighing mechanism 2 can accurately discharge the powder from the discharge port 12. The outer hopper mechanism 1 can receive the powder during the tilting process and guide the discharge, reducing the residue in the weighing hopper.

[0039] Example 2

[0040] This embodiment is based on the aforementioned embodiment. In this embodiment, as shown in Figure 1-2, a discharge control mechanism is provided inside the discharge port 44. The discharge control mechanism includes a discharge rotating shaft 45 and a discharge control plate 46 disposed on the discharge rotating shaft 45. A control drive mechanism is connected to the end of the discharge rotating shaft 45 and is disposed outside the conveying pipe. The discharge control mechanism is used to adjust the size of the opening of the discharge port 44 of the conveying pipe by driving the discharge rotating shaft 45 to rotate the discharge control plate 46. The conveying motor drives the conveying shaft 42 to rotate, which in turn drives the spiral conveying blades 43 to rotate, conveying the powder along the conveying pipe to the discharge port 44 at the end. The control drive mechanism of the discharge control mechanism drives the discharge rotating shaft 45 to rotate, which in turn drives the discharge control plate 46 to rotate. By changing the angle of the discharge control plate 46, the size of the opening of the discharge port 44 is adjusted, thereby controlling the discharge amount of powder. Compared to traditional powder discharging devices, which struggle to precisely control the discharge amount and are prone to over- or under-discharge, this invention enables controllable adjustment of the powder discharge amount, improving the accuracy of powder discharging, meeting the precise requirements of powder discharge in different production scenarios, and enhancing the stability of the production process and product quality.

[0041] In a preferred embodiment, a rotating support head 48 is connected to the end of the discharge shaft 45 opposite to the control drive mechanism. The end of the discharge shaft 45 is rotatably mounted within the rotating support head 48, which is mounted on the conveying pipe. The discharge shaft 45 rotates within the rotating support head 48, ensuring the stability and coaxiality of its rotation, allowing the discharge control plate 46 to smoothly and accurately adjust the opening size of the discharge port 44. Compared to existing technologies where the discharge shaft 45 lacks effective support and is prone to wobbling and deviation during rotation, affecting the accuracy and stability of the discharge control plate 46's adjustment of the discharge port 44 opening size, the device in this embodiment enhances the stability of the discharge shaft 45 during rotation, avoiding inaccurate discharge control caused by shaft wobbling, further improving the precision and reliability of discharge control, and extending the service life of the discharge control mechanism.

[0042] In a preferred embodiment, the control drive mechanism includes a control drive motor 49. The control drive motor 49 is connected to a drive pulley 410 via a motor shaft. The drive pulley 410 is connected to a driven pulley 411 via a belt drive. The driven pulley 411 is connected to the discharge shaft 45. After the operator starts the drive motor 49, the motor shaft drives the drive pulley 410 to rotate, transmitting power to the driven pulley 411 via belt drive. The driven pulley 411 is connected to the discharge shaft 45, thereby driving the discharge shaft 45 to rotate, enabling the discharge control plate 46 to adjust the opening size of the discharge port 44. This device uses belt drive, which is simple in structure, provides smooth transmission, and has a certain buffering and vibration absorption capacity, reducing impact and vibration during power transmission. Simultaneously, it facilitates adjustment of the drive motor speed, thereby flexibly controlling the rotation angle and speed of the discharge shaft 45, achieving more precise control over the discharge volume. It should be noted that the connection between the pulley and the transmission belt in this embodiment has a certain anti-slip structure support. For example, both the pulley and the transmission belt are provided with teeth that can mesh with each other, thereby preventing the belt from slipping during transmission.

[0043] In a preferred embodiment, a pipe vibrator 412 is installed on the conveying pipeline. The pipe vibrator 412 includes a vibrating base 413 fitted onto the conveying pipeline, a fixing ring 414 sleeved around the vibrating base 413 and the conveying pipeline, and a vibrating impact head inside the pipe vibrator 412, which is connected to a vibration driving mechanism. The fixing ring 414 is used to fix the relative position of the pipe vibrator 412 and the conveying pipeline, and the vibration driving mechanism is used to drive the vibrating impact head to reciprocate and act on the conveying pipeline. The pipe vibrator 412 can drive the vibrating impact head to reciprocate through the vibration driving mechanism, and the vibrating impact head continuously impacts the conveying pipeline, causing the conveying pipeline to vibrate. The fixing ring 414 tightly fixes the pipe vibrator 412 to the conveying pipeline, ensuring that the vibration can be effectively transmitted to the conveying pipeline. Compared to existing technologies where powder is prone to accumulation and blockage during transport in pipelines, affecting smooth delivery and stable discharge, the device in this embodiment effectively prevents powder accumulation and blockage in the pipeline through vibration generated by the pipeline vibrator 412. This ensures good powder flowability within the pipeline, guarantees smooth powder delivery and discharge, improves discharge efficiency and stability, and reduces equipment failure and maintenance costs. Preferably, the vibration drive mechanism can use pneumatic drive as the power source, driving the reciprocating motion of the vibrating head through air pressure changes.

[0044] In a preferred embodiment, a storage mechanism 415 is also included. The storage mechanism 415 is disposed above the conveying pipe and is internally connected to the conveying pipe. A material discharge control mechanism 416 is disposed at the bottom of the storage mechanism 415. The material discharge control mechanism 416 is used to control the material in the storage mechanism 415 to fall into the conveying pipe by opening or closing the channel. The material discharge control mechanism 416 can be directly set up using the material discharge control mechanism 416 in the prior art. For example, a swing-type hopper door is set up, and the material discharge is controlled by opening or closing the hopper door. The material discharge control mechanism 416 can also be set up with the same structure as the discharge control mechanism in the aforementioned embodiment, so as to make the material discharge control more accurate.

[0045] Example 3

[0046] This embodiment is based on the foregoing embodiments. In this embodiment, as follows: Figure 1 , Figures 5-7As shown, the tilting and weighing mechanism 2 includes a tilting hopper 21 and a weighing tilting assembly 22 connected to the tilting hopper 21. The weighing tilting assembly 22 is connected to the outer hopper mechanism 1, and a weighing sensor 23 is provided on the weighing tilting assembly 22. The weighing tilting assembly 22 includes a rotating rod 24 connected to the tilting hopper 21 and a fixed rod 25 connected to the rotating rod 24. A connecting protrusion 26 is provided at the end of the rotating rod 24, and a connecting groove 27 is provided on the fixed rod 25. A rotary bearing 28 is provided between the connecting protrusion 26 and the connecting groove 27. The rotating rod 24 is used to connect to an external rotary drive mechanism and drive the tilting hopper 21 to rotate. The fixed rod 25 is used to provide support for the tilting hopper 21. The weighing sensor 23 is used to obtain the pressure applied by the tilting hopper 21 to the tilting and weighing mechanism 2. Figure 6 and Figure 7 The images show two exemplary structures that can be provided on both sides of the weighing and flipping assembly 22. Both are structures in which the connecting protrusion 26 and the connecting groove 27 are engaged. The only difference is that the connecting protrusion 26 required on the side bearing the rotational driving torque is larger in size to enhance the load-bearing capacity.

[0047] In this embodiment, the powder material falls under gravity through the feed inlet 11 at the top of the outer hopper mechanism 1 and enters the tilting hopper 21, which is initially in a horizontal state. A guiding mechanism can be installed above the tilting hopper 21 to guide the material into the hopper 21; its installation position should not affect the tilting movement of the tilting hopper 21. During this process, the weighing sensor 23 mounted on the weighing and tilting assembly 22 connected to the tilting hopper 21 can sense and acquire the pressure applied by the tilting hopper 21 in real time. According to the principle of mechanics, the gravity of the powder material on the tilting hopper 21 is transmitted to the weighing sensor 23 in the form of pressure. The sensor converts the pressure signal into an electrical signal, and then converts it into a specific weight value of the powder material, thereby achieving more accurate weighing of the powder. After the weighing process is completed, the rotating rod 24 begins to rotate under the drive of the external rotation drive mechanism. Since the rotating rod 24 is connected to the tipping hopper 21, it can drive the tipping hopper 21 to rotate synchronously, causing the tipping hopper 21 to gradually flip from a horizontal state to an inclined state, so that the powder material is flipped out, until the weighed powder material is smoothly discharged from the discharge port 12 at the bottom of the outer hopper mechanism 1. The rotating rod 24 and the fixed rod 25 are connected by a connecting protrusion 26, a connecting groove 27, and a rotating bearing 28. On the one hand, this structure ensures that the rotating rod 24 has good flexibility and stability during rotation, making the tipping action of the tipping hopper 21 smooth and controllable; on the other hand, the fixed rod 25 provides stable support for the tipping hopper 21, ensuring that the position of the tipping hopper 21 is fixed during the weighing process, thereby ensuring the accuracy of the weighing data. By measuring the weight of the powder using the weighing sensor 23 and achieving the tipping and unloading function of the tipping hopper 21 through the cooperation of the rotating rod 24 and the fixed rod 25, this structure realizes the orderly process of powder feeding, weighing, and unloading. It not only meets the high-precision weighing requirements of powder materials but also features efficient unloading, significantly improving the accuracy, efficiency, and quality of powder weighing operations. Those skilled in the art will understand that the outer hopper mechanism 1 and the weighing and tipping assembly 22 do not necessarily have a supporting connection. When a fixed connection is required, it can be configured as a fixed supporting structure. When the outer hopper mechanism 1 needs to allow the tipping motion of the components to move, it can be configured as a gap-mounted structure where they do not contact each other, with external support provided by the fixed rod 25. Both of these combinations are conventional techniques in the art, and those skilled in the art can directly use relevant technologies to set them up.

[0048] Preferably, the weighing sensor 23 of this utility model can be of the following specific models: HBM Z6FC6, TE FX29 or LT-CG-208 wireless transmission type sensor.

[0049] In a preferred embodiment, the weighing and tilting assembly 22 is connected to the device bracket 3 via a fixed rod 25. The fixed rod 25, connected to one side of the tilting hopper 21, is hollow inside. A transmission rod 29 is connected to the end of the fixed rod 25. A torque transmission shaft 210 is connected between the transmission rod 29 and the rotating rod 24 through the inside of the fixed rod 25. A connecting key 211 connects the torque transmission shaft 210 and the transmission rod 29. The tilting drive motor 212 is connected to the transmission rod 29. The tilting drive motor 212 transmits power to the rotating rod 24 through the transmission rod 29, the torque transmission shaft 210, and the connecting key 211, thereby driving the tilting hopper 21 to tilt. The hollow structure inside the fixed rod 25 provides installation space for the torque transmission shaft 210, making the power transmission path more reasonable. The tilting of the hopper 21 is achieved through the cooperation of the motor drive and the transmission components, making the power transmission for the tilting of the hopper 21 stable and reliable, and improving the stability and reliability of the device operation. A corresponding rotary support structure can also be provided between the torque drive shaft 210 and the fixed rod 25 to support the stable movement of both, for example, by adding a bearing between the two components.

[0050] In a preferred embodiment, the external hopper mechanism 1 includes an upper feed hopper 13 disposed above and a lower feed hopper 14 connected below the upper feed hopper 13. A flexible telescopic joint 15 connects the upper feed hopper 13 and the lower feed hopper 14. The lower feed hopper 14 is used to connect to an external feeding vibration mechanism and vibrate to discharge the material. After the rotary vibration drive mechanism is started, it transmits power to the vibration drive rod, which rotates periodically under the action of power. Since the vibration drive rod is hinged to the vibration connecting rod, the movement of the vibration drive rod can drive the vibration connecting rod to swing accordingly, thereby causing the lower feed hopper 14, which is hinged to the vibration connecting rod, to reciprocate. During the reciprocating motion of the lower feed hopper 14, the powder material inside is subjected to vibration, reducing the friction and adhesion between particles and significantly improving the flowability, thereby promoting the smooth downward flow of the powder material. At the same time, the flexible expansion joint 15 connecting the upper feed hopper 13 and the lower feed hopper 14 plays a role. The flexible expansion joint 15 has good flexibility and extensibility. Under the premise of ensuring effective connection between the upper feed hopper 13 and the lower feed hopper 14, it can adapt to the reciprocating vibration of the lower feed hopper 14, avoid loosening and leakage at the connection due to vibration, and ensure the sealing and continuity of the powder material conveying process.

[0051] In a preferred embodiment, an activation cone 16 is provided inside the feed hopper 14. The activation cone 16 is positioned below the tipping hopper 21, with its pointed tip facing the tipping hopper 21. The activation cone 16 is used to break up arches in the powder material through its pointed tip. With the pointed tip facing the tipping hopper 21, the activation cone 16 can effectively insert into the material pile during the falling process of the powder material, breaking up the arched structure formed by the interaction between particles, preventing material accumulation and blockage, and ensuring that the powder material can smoothly pass through the feed hopper 14 and enter the subsequent processing stage.

[0052] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
