Description

Technical Field

[0001] This invention relates to the field of particulate matter batching technology, and particularly to a particulate matter batching device and particulate matter batching equipment. Background Technology

[0002] Currently, most of these devices use rigid valve structures such as gate valves, butterfly valves, or ball valves to control the opening and closing of the discharge port. However, these structures typically only allow for two states: fully open or fully closed, or have only a limited number of fixed opening positions, making it difficult to achieve continuous and precise adjustment of the discharge port opening. In actual production, the particle size, flowability, and batching accuracy requirements of granular materials often vary depending on the type of material and process conditions. If the discharge port opening is not adjustable or has a limited adjustment range, it can easily lead to problems such as unstable discharge speed and insufficient batching accuracy. Especially when processing granular materials of different sizes, a fixed discharge port can easily cause blockage or flow rate loss due to mismatched orifice diameters, affecting the uniformity and accuracy of batching.

[0021] This invention proposes a particulate matter batching device, aiming to solve the technical problem of how to improve the batching effect of particulate matter.

[0022] In embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the particulate material dispensing device includes: a dispensing container 10, the bottom of which has a discharge port 11 for discharging particulate material from the dispensing container 10; and an opening adjustment mechanism 20, which includes a fixed member 21, a movable member 22, and a flexible valve plate 23. The fixed member 21 is installed on the outside of the dispensing container 10, the movable member 22 is movably installed on the fixed member 21, and the flexible valve plate 23 is strip-shaped, having a fixed end and an adjusting end. The fixed end is fixedly connected to the movable member 22 so that the fixed end moves with the movable member 22; the adjusting end extends to the bottom of the mixing container 10 and is slidably engaged with the bottom wall of the mixing container 10; the adjusting end is used to gradually block the discharge port 11 when the movable member 22 moves in the first direction, and to gradually open the discharge port 11 when the movable member 22 moves in the second direction, so that the opening degree of the discharge port 11 is adjusted with the movement of the movable member 22, wherein the first direction and the second direction are opposite directions.

[0023] In this embodiment, the main function of the particulate material dispensing device is to accurately measure and dispense particulate materials. This device is commonly used in chemical, pharmaceutical, and food processing industries to ensure the accuracy of material proportions during production.

[0024] The function of the batching container 10 is to hold the granular material to be batched. This container usually has a certain volume and is designed with a structure to facilitate the outflow of material. The discharge port 11 is located at the bottom of the batching container 10 and is the channel through which the granular material flows out of the batching container 10. The size and shape of the discharge port 11 directly affect the outflow speed and flow rate of the material.

[0025] The core function of the opening adjustment mechanism 20 is to control the opening degree of the discharge port 11. By operating the opening adjustment mechanism 20, precise control of the material outflow rate can be achieved, thereby meeting different batching requirements. The fixed component 21, as the supporting structure of the opening adjustment mechanism 20, is installed on the outside of the batching container 10, providing a stable mounting base for the movable component 22 and the flexible valve plate 23. The movable component 22 is movably mounted on the fixed component 21 and is the key component in the opening adjustment mechanism 20 that enables movement. The movement of the movable component 22 directly drives the flexible valve plate 23 to move. The flexible valve plate 23 is strip-shaped and has a certain degree of flexibility. The flexible valve plate 23, through its adjusting end, cooperates with the bottom wall of the batching container 10 to block or open the discharge port 11. The fixed end is part of the flexible valve plate 23 and is fixedly connected to the movable component 22. The movement of the fixed end is consistent with the movement of the movable component 22. The adjusting end is another part of the flexible valve plate 23, which extends to the bottom of the mixing container 10. The adjusting end acts directly on the discharge port 11 through sliding cooperation with the bottom wall of the mixing container 10 to control its opening degree.

[0026] The fastener 21 is installed on the outside of the dispensing container 10, providing stable support for the entire opening adjustment mechanism 20. For example, the fastener 21 can be fixed to the outer wall of the dispensing container 10 by welding, bolting, or snap-fitting. In one implementation, the fastener 21 can be a simple bracket structure, fixed to the side wall of the dispensing container 10 by bolts. In another implementation, the fastener 21 can be a ring structure, fitted around the bottom outer side of the dispensing container 10.

[0027] The movable component 22 is movably mounted to the fixed component 21. The movable component 22 can be mounted in various ways to ensure it can move along a predetermined path. For example, the movable component 22 can be designed to slide in a groove inside the fixed component 21, or to achieve linear motion via a guide rail structure. In one implementation, the movable component 22 can be a simple slider that reciprocates in a linear groove inside the fixed component 21. In another implementation, the movable component 22 can be a component with rollers that rolls on a track of the fixed component 21.

[0028] The fixed end of the flexible valve plate 23 is fixedly connected to the movable member 22 so that the fixed end moves with the movable member 22. The flexible valve plate 23 can be made of a material with a certain degree of flexibility, such as rubber, silicone, or elastic plastic. The connection between the fixed end and the movable member 22 can include bonding, riveting, or fixing with a clamp. For example, the fixed end of the flexible valve plate 23 can be bonded to the side of the movable member 22, or it can be fixed to the movable member 22 with screws.

[0029] The adjusting end extends to the bottom of the mixing container 10 and slidably engages with the bottom wall of the mixing container 10. This sliding engagement ensures that the adjusting end can closely conform to the bottom wall of the mixing container 10 during movement, effectively controlling the opening of the discharge port 11. For example, the adjusting end can simply be placed on the bottom wall of the mixing container 10, relying on its own weight or preload to maintain contact. In another implementation, the adjusting end can be designed with an arc that matches the bottom wall of the mixing container 10 to increase the contact area and sliding stability.

[0030] The first and second directions are opposite. Through the linear reciprocating motion of the movable member 22, the flexible valve plate 23 is pushed and pulled, and its adjusting end slides above the discharge port 11, thereby achieving continuous adjustment of the opening degree of the discharge port 11. For example, when the movable member 22 moves away from the discharge port 11, the adjusting end of the flexible valve plate 23 gradually moves away from above the discharge port 11, opening the discharge port 11; when the movable member 22 moves closer to the discharge port 11, the adjusting end of the flexible valve plate 23 gradually covers the discharge port 11, blocking it. This design allows the opening degree of the discharge port 11 to be steplessly adjusted from completely closed to completely open.

[0031] When the operator needs to reduce the opening of the discharge port 11, the movable part 22 is moved in a first direction (e.g., inward). At this time, the fixed end of the flexible valve plate 23 connected to the movable part 22 moves accordingly, causing the adjusting end to slide on the bottom wall of the mixing container 10, gradually covering the discharge port 11. As the area of ​​the adjusting end covering the discharge port 11 increases, the actual opening area of ​​the discharge port 11 gradually decreases, thereby reducing the material outflow velocity. Conversely, when the opening of the discharge port 11 needs to be increased, the operator drives the movable part 22 in a second direction (e.g., outward). The adjusting end of the flexible valve plate 23 then moves away from above the discharge port 11, causing the opening area of ​​the discharge port 11 to gradually increase, thereby increasing the material outflow velocity. In this way, the opening degree of the discharge port 11 can be continuously and steplessly adjusted as the movable part 22 moves. For example, when feeding small, highly fluid materials, the discharge port 11 can be adjusted to a smaller opening to prevent the material from flowing out too quickly; when feeding larger, less fluid materials, the discharge port 11 can be adjusted to a larger opening to ensure that the material flows out smoothly.

[0032] The particulate matter batching device of this application achieves continuous and precise adjustment of the opening of the discharge port 11 by introducing an opening adjustment mechanism 20. The solution of this application provides stepless adjustment capability. This continuous adjustment capability allows the material outflow rate to be precisely controlled according to actual needs, effectively avoiding problems such as unstable discharge rate and insufficient batching accuracy caused by the non-adjustable opening or limited adjustment range in existing technologies. Furthermore, the sliding fit between the flexible valve plate 23 and the bottom wall of the batching container 10 can better adapt to the characteristics of different materials, reducing the risk of blockage or flow rate runaway caused by mismatched orifice diameters, thereby improving the uniformity and accuracy of batching.

[0033] For example, such as Figure 2 and Figure 3 As shown, the fixing member 21 is provided with a movable channel 211, the movable member 22 and the flexible valve plate 23 are movably installed in the movable channel 211, and the adjusting end of the flexible valve plate 23 extends out of the movable channel 211 and is slidably engaged with the bottom wall of the dispensing container 10.

[0034] The fixing member 21 is a component of the opening adjustment mechanism 20, and its function is to provide a mounting base and motion guide for the moving part 22 and the flexible valve plate 23. The fixing member 21 can be a separate housing structure, for example, fixed to the outside of the dispensing container 10 by bolts or welding; or, the fixing member 21 can also be part of the bottom structure of the dispensing container 10, for example, formed by integral molding.

[0035] The movable channel 211 is disposed inside the fixed member 21, and its function is to provide precise trajectory restriction and support for the movement of the movable member 22 and the flexible valve plate 23. The movable channel 211 can be a straight channel inside the fixed member 21, for example, formed by milling or casting; or it can be formed by a combination of multiple guide rods and guide holes to ensure that the movable member 22 and the flexible valve plate 23 move along a preset path.

[0036] The movable component 22 is a movable part in the opening adjustment mechanism 20. Its function is to drive the flexible valve plate 23 to reciprocate, thereby adjusting the opening of the discharge port 11. The movable component 22 can be a slider whose shape matches the cross-section of the movable channel 211, such as a rectangular slider or a T-shaped slider; or it can be a plate-like structure with a guide pin that slides within the movable channel 211.

[0037] The flexible valve plate 23 is strip-shaped, with its fixed end connected to the movable part 22 and its adjusting end used to cooperate with the bottom wall of the dispensing container 10 to block or open the discharge port 11. The flexible valve plate 23 can be made of materials with certain elasticity and wear resistance, such as polymer materials such as silicone rubber, polyurethane or fluororubber; or it can be composed of multi-layer composite materials to take into account flexibility, wear resistance and sealing performance.

[0038] The adjusting end of the flexible valve plate 23 is the part that directly contacts the bottom wall of the dispensing container 10 and adjusts the opening of the discharge port 11. This adjusting end usually has a certain width and thickness, and its edge can be designed to be straight or curved to adapt to the shape of the discharge port 11 and ensure good sliding fit and sealing effect.

[0039] The bottom wall of the dispensing container 10 is the surface on which the adjusting end of the flexible valve plate 23 slides. This bottom wall typically requires a smooth, flat surface with a certain degree of wear resistance to reduce sliding friction and extend the service life of the flexible valve plate 23. The adjusting end of the flexible valve plate 23 and the bottom wall of the dispensing container 10 can slide relative to each other while maintaining tight contact to prevent material leakage. This fit can be achieved by selecting a suitable combination of materials (e.g., a low-friction coefficient flexible valve plate 23 material with a smooth bottom wall surface); or by applying an appropriate preload between the contact surfaces or by using a self-lubricating material to optimize the sliding performance.

[0040] By setting a movable channel 211 in the fixed component 21, and guiding the movable component 22 and the flexible valve plate 23 within this channel, the problems of possible offset, jamming, or positional deviation during the movement of the movable component 22 and the flexible valve plate 23 are effectively solved. The movable channel 211 provides a stable movement trajectory and support for the movable component 22 and the flexible valve plate 23, ensuring their smoothness and accuracy throughout the entire adjustment stroke. This precise guiding effect allows the adjusting end of the flexible valve plate 23 to maintain a stable posture and a tight, sliding fit with the bottom wall of the dispensing container 10, thereby ensuring the continuity and precision of the opening adjustment of the discharge port 11. By providing clear motion constraints, frictional resistance is significantly reduced, wear is decreased, and the reliability and repeatability of the adjustment are improved, making the dispensing process of granular materials more stable and accurate.

[0041] For example, such as Figures 1 to 3 As shown, the opening adjustment mechanism 20 also includes an adjustment sleeve 24, which is rotatably sleeved on the fixed member 21. One end of the movable member 22 extends out of the movable channel 211 away from the discharge port 11. The adjustment sleeve 24 and the end of the movable member 22 extending out of the movable channel 211 are threadedly engaged, so that when the adjustment sleeve 24 rotates, it can drive the movable member 22 to make linear motion.

[0042] Adjusting sleeve 24 is a hollow structural component, typically with threads machined inside or outside. It is primarily used to convert rotary motion into linear motion or as a rotary support for other components. Adjusting sleeve 24 can be made of various materials. For example, to ensure sufficient strength and wear resistance, stainless steel, carbon steel, or aluminum alloy can be selected. If there are special requirements for weight or corrosion resistance, high-strength engineering plastics such as polyoxymethylene (POM) or polyetheretherketone (PEEK) can also be used.

[0043] The adjusting sleeve 24 can rotate about the axis of the fixed member 21 while maintaining its axial position relatively stable. This rotatable fit can be achieved by providing a bearing (e.g., a ball bearing, a sliding bearing) or bushing between the fixed member 21 and the adjusting sleeve 24 to reduce rotational friction and ensure smooth movement; or, a precise clearance fit can be used to allow the adjusting sleeve 24 to rotate freely outside the fixed member 21.

[0044] One end of the movable part 22 extends out of the movable channel 211 away from the discharge port 11. This provides the necessary space for the threaded engagement between the adjusting sleeve 24 and the movable part 22, allowing adjustment operations to be performed outside the movable channel 211, thus facilitating user adjustment and maintenance. The thread of the adjusting sleeve 24 meshes with the thread of the protruding end of the movable part 22. Specifically, the adjusting sleeve 24 may have an internal thread, while the protruding end of the movable part 22 is machined with a matching external thread. The type of thread can be selected according to the required transmission accuracy and load-bearing capacity; for example, trapezoidal threads, rectangular threads, or ordinary triangular threads can be used. The final effect of this threaded engagement is that when the adjusting sleeve 24 rotates, it drives the movable part 22 to make linear motion. That is, by rotating the adjusting sleeve 24, utilizing the helical characteristics of the thread, the rotational motion is precisely converted into linear displacement of the movable part 22 along its axial direction.

[0045] By introducing the adjusting sleeve 24 and its threaded engagement mechanism with the movable part 22, precise control of the linear motion of the movable part 22 is achieved. When the operator rotates the adjusting sleeve 24, the threaded pair converts the rotational motion into the linear motion of the movable part 22, thereby driving the movable part 22 to move in a straight line within the movable channel 211. The precise linear movement of the movable part 22 directly drives the flexible valve plate 23 to make corresponding displacements, enabling the flexible valve plate 23 to gradually block or open the discharge port 11 with extremely high precision. This design cleverly transforms easily operable rotational motion into precise linear adjustment, ensuring continuous and fine control of the opening degree of the discharge port 11.

[0046] For example, such as Figure 2 and Figure 3 As shown, the fixing member 21 includes a sleeve portion 212 and a mounting portion 213. The upper end of the sleeve portion 212 is sleeved on the bottom end of the dispensing container 10, and the lower end of the sleeve portion 212 has a discharge port 214 opposite to the discharge port 11. The mounting portion 213 is connected to the outer wall of the sleeve portion 212. The movable channel 211 is provided in the mounting portion 213 and passes through the sleeve portion 212, so that the adjusting end of the flexible valve plate 23 can extend into the sleeve portion 212 from the movable channel 211 and cooperate with the bottom wall of the dispensing container 10.

[0047] The fastener 21 consists of a sleeve portion 212 and a mounting portion 213. The sleeve portion 212 is typically tubular or cylindrical, and its main function is to provide a stable structural support and material flow channel, and to connect to the bottom end of the dispensing container 10. The mounting portion 213 is a structure for connecting and fixing other components, such as the movable channel 211 and the movable part 22, which typically extends from or is attached to the outer wall of the sleeve portion 212.

[0048] The upper end of the sleeve 212 is connected to the bottom end of the mixing container 10 by a sleeve-fitting method. This connection method ensures a tight fit between the components and provides good positioning and support. The lower end of the sleeve 212 has a discharge port 214, which is vertically opposite to the discharge port 11 of the mixing container 10, in order to ensure that the particulate material can be discharged smoothly.

[0049] The mounting part 213 is connected to the outer wall of the sleeve part 212. This connection can be achieved by welding, bolting, integral casting, or mechanical connection methods such as snap-fit ​​or dovetail groove. The movable channel 211 is located inside the mounting part 213 and penetrates the wall of the sleeve part 212, forming a continuous path. This path can be a rectangular groove, a circular hole, or an irregularly shaped hole, and its function is to provide a movement trajectory for the movable part 22 and the flexible valve plate 23. The adjusting end of the flexible valve plate 23 can extend into the sleeve part 212 through the movable channel 211 and form a sliding fit with the bottom wall of the dispensing container 10 to effectively block and open the discharge port 11.

[0050] By subdividing the fixing member 21 into a sleeve portion 212 and a mounting portion 213, and optimizing the integration of the movable channel 211, a stable sliding fit between the adjusting end of the flexible valve plate 23 and the bottom wall of the dispensing container 10 is ensured, thereby improving the accuracy and sealing of the opening adjustment. The sleeve portion 212, as the core support structure, is fitted onto the bottom of the dispensing container 10 at its upper end, forming a stable connection base. The mounting portion 213 is connected to the outer wall of the sleeve portion 212, further enhancing the rigidity of the entire fixing member 21 and reducing potential vibration interference during operation. The movable channel 211 is cleverly positioned in the mounting portion 213 and extends through the sleeve portion 212, forming a continuous and smooth path. This path allows the adjusting end of the flexible valve plate 23 to smoothly extend from the external mounting portion 213 into the interior of the sleeve portion 212, ultimately achieving a stable and tight sliding fit with the bottom wall of the dispensing container 10. This structural design enables the flexible valve plate 23 to maintain a stable movement trajectory and reliable sealing state when adjusting the opening of the discharge port 11, thereby preventing the problem of unstable movement of the flexible valve plate 23 and material leakage caused by the unstable structure of the fixing component 21, and significantly improving the accuracy and reliability of the batching.

[0051] For example, such as Figure 4 As shown, the inner wall of the sleeve portion 212 is provided with a first guide groove 215. The extension trajectory of the first guide groove 215 is adapted to the bottom shape of the dispensing container 10. The side of the adjusting end is slidably engaged with the first guide groove 215 so that the adjusting end is kept in close contact with the bottom wall of the dispensing container 10.

[0052] The first guide groove 215 is a structure provided on the inner wall of the sleeve portion 212, which serves to provide a precise movement trajectory and stable support for the adjusting end of the flexible valve plate 23. The first guide groove 215 can be in the form of a groove, such as a V-shaped groove, a U-shaped groove or a rectangular groove, or it can be in the form of a protrusion, such as a series of guide ribs or guide posts.

[0053] The geometry, orientation, and curvature of the first guide groove 215 match the actual contour of the bottom of the dispensing container 10. For example, if the bottom of the dispensing container 10 is flat, the first guide groove 215 can be designed as a straight line; if the bottom of the dispensing container 10 is conical or arc-shaped, the first guide groove 215 can be designed as a corresponding inclined straight line segment or curved segment.

[0054] The side of the adjusting end forms a structure with the inner wall or side wall of the first guide groove 215 that allows relative sliding movement but restricts movement in other directions (such as perpendicular to the sliding direction). For example, the side of the adjusting end can be designed as a flat surface to mate with a rectangular groove, or designed with a flange or groove to mate with a V-shaped groove or a U-shaped groove.

[0055] By providing a first guide groove 215 on the inner wall of the sleeve portion 212, and adapting the extension trajectory of the first guide groove 215 to the bottom shape of the dispensing container 10, while allowing the side of the adjusting end of the flexible valve plate 23 to slide in conjunction with the first guide groove 215, it is ensured that the adjusting end can always be precisely guided during movement. The introduction of the first guide groove 215 provides a preset sliding path for the adjusting end that perfectly matches the bottom shape of the dispensing container 10. When the movable part 22 drives the flexible valve plate 23 to move, the side of the adjusting end slides within the first guide groove 215. The first guide groove 215 applies a constraint force to the adjusting end, ensuring that it always moves along the predetermined trajectory and closely adheres to the bottom wall of the dispensing container 10. This close fit not only ensures the accuracy of the opening adjustment of the discharge port 11 but also effectively prevents material leakage from gaps during adjustment, thereby improving the accuracy of dispensing and the sealing performance of the device.

[0056] For example, such as Figure 4 As shown, the inner wall of the movable channel 211 is provided with a second guide groove 216. The second guide groove 216 extends along the movement direction of the flexible valve plate 23 in the movable channel 211. One end of the second guide groove 216 near the sleeve portion 212 is connected to the first guide groove 215. The side of the flexible valve plate 23 is slidably engaged with the second guide groove 216.

[0057] The second guide groove 216 is a structure disposed on the inner wall of the movable channel 211 to guide the movement of the flexible valve plate 23. In one specific embodiment, the second guide groove 216 can be designed as a V-shaped groove, forming a V-shaped fit with the side of the flexible valve plate 23, or as a U-shaped groove, in which the side of the flexible valve plate 23 is embedded. Alternatively, the second guide groove 216 can also be a raised guide rib, engaging with the groove on the side of the flexible valve plate 23. Its function is to provide initial, direct guidance and support for the movement of the flexible valve plate 23 within the movable channel 211.

[0058] The length direction of the second guide groove 216 is consistent with the direction of the linear reciprocating motion of the flexible valve plate 23 within the movable channel 211. Typically, the second guide groove 216 can be straight, parallel to the linear motion direction of the flexible valve plate 23. In some cases, if the flexible valve plate 23 has a slight arcuate movement within the movable channel 211, the second guide groove 216 can also be arcuate accordingly. This design aims to ensure that the flexible valve plate 23 can move smoothly and linearly within the movable channel 211, preventing it from deviating from the preset path.

[0059] The end of the second guide groove 216 is spatially connected to or aligned with the beginning of the first guide groove 215, forming a continuous guide path. For example, the opening end of the second guide groove 216 can be directly aligned with the inlet end of the first guide groove 215 and smoothly transition, or a transition section can be used to gradually widen or deepen the second guide groove 216 to adapt to the shape of the first guide groove 215, achieving a seamless connection. This ensures that when the flexible valve plate 23 enters the sleeve portion 212 from the movable channel 211, it can smoothly transition from the second guide groove 216 to the first guide groove 215, avoiding jamming or impact.

[0060] The flexible valve plate 23 has contact with the inner wall of the second guide groove 216, allowing relative sliding while restricting the degree of freedom of the flexible valve plate 23 perpendicular to the direction of movement. As a specific implementation, the side of the flexible valve plate 23 can be designed as a protrusion or groove matching the shape of the second guide groove 216. To reduce sliding resistance, the side of the flexible valve plate 23 can be made of a material with a low coefficient of friction, or a lubricant can be applied to the mating surface. This ensures that the flexible valve plate 23 is always guided and constrained when moving within the active channel 211, reducing wobbling and improving the stability and accuracy of the movement.

[0061] By providing a second guide groove 216 on the inner wall of the movable channel 211 of the fixing member 21, and extending it along the movement direction of the flexible valve plate 23 within the movable channel 211, a direct and stable guide is provided for the movement of the flexible valve plate 23 within the movable channel 211. When the movable member 22 drives the flexible valve plate 23 to move, the side of the flexible valve plate 23 slidably engages with the second guide groove 216, enabling the flexible valve plate 23 to maintain a precise linear movement trajectory within the movable channel 211, effectively avoiding trajectory deviation caused by lack of guidance. The end of the second guide groove 216 near the sleeve portion 212 connects with the first guide groove 215 on the inner wall of the sleeve portion 212, forming a continuous guide path from the movable channel 211 to the sleeve portion 212. This seamless connection ensures that the flexible valve plate 23 can smoothly and easily transition to the guidance of the first guide groove 215 when entering the sleeve portion 212 from the movable channel 211. Therefore, the adjusting end of the flexible valve plate 23 can always maintain a tight fit with the bottom wall of the dispensing container 10, thereby maintaining effective sealing throughout the adjustment process and ensuring the accuracy of the opening adjustment of the discharge port 11.

[0062] For example, such as Figure 2 and Figure 3 As shown, the opening adjustment mechanism 20 also includes a sealing ring 25, which is installed in the movable channel 211. The movable part 22 is sealed to the sealing ring 25 so that when the discharge port 214 is blocked, the mixing container 10, the sleeve part 212 and the movable channel 211 can form a closed space.

[0063] A sealing ring 25 is an elastic or plastic element used to prevent fluid or particulate matter from leaking from a connection. This sealing ring 25 can be an O-ring, which fills the mating gap through its own elastic deformation to achieve a seal; or it can be a lip seal, whose lip adheres tightly to the mating surface under pressure to enhance the sealing effect.

[0064] The sealing ring 25 is positioned along the path of movement of the movable part 22 to ensure effective sealing contact. For example, the sealing ring 25 can be placed in a pre-set annular groove on the inner wall of the movable channel 211 and fixed by compression or adhesion; alternatively, the sealing ring 25 can be directly embedded into the inner wall of the movable channel 211 by interference fit, utilizing the elasticity of the material to maintain its position. As the movable part 22 moves within the movable channel 211, it maintains close contact with the sealing ring 25, thereby preventing the exchange of particulate material or the external environment through the gap between the movable channel 211 and the movable part 22. For example, the outer surface of the movable part 22 can be designed to fit tightly against the inner diameter of the sealing ring 25, achieving dynamic sealing through sliding friction; alternatively, the sealing ring 25 can apply a radial preload to the movable part 22, keeping it in a compressed state as the movable part 22 moves, thus forming an effective seal.

[0065] When the discharge port 214 is blocked, the batching container 10, the sleeve 212 and the moving channel 211 can form a closed space to ensure that the entire material channel system is in a completely closed state when the material is stopped, preventing material leakage, moisture or external contamination, and at the same time preventing external air from entering the system and affecting the material properties.

[0066] By introducing a sealing ring 25 into the opening adjustment mechanism 20 and installing it within the movable channel 211, sealing it with the movable part 22, the problems of leakage and moisture deterioration that may occur when the discharge port 11 is blocked are effectively solved. By setting the sealing ring 25 and ensuring its tight fit with the movable part 22, the sealing ring 25 maintains a sealing effect on the movable part 22 as it moves, thereby blocking potential leakage paths between the movable channel 211 and the external environment. Therefore, when the flexible valve plate 23 completely blocks the discharge port 11, the mixing container 10, the sleeve portion 212, and the interior of the movable channel 211 form a complete, sealed space isolated from the external environment, ensuring the airtightness of the entire mixing system.

[0067] For example, such as Figure 3 As shown, the mounting part 213 includes a fixing part 217 and a connecting sleeve 218. The fixing part 217 is integrally formed with the sleeve part 212. The connecting sleeve 218 is sleeved on the end of the fixing part 217 away from the sleeve part 212. The connecting sleeve 218 is provided with a sealing groove. The sealing ring 25 is installed in the sealing groove. The end of the fixing part 217 presses the sealing ring 25 into the sealing groove.

[0068] The mounting portion 213 can be a separate component or integrated into the main structure. The fixing portion 217 is a component of the mounting portion 213, characterized by being integrally formed with the sleeve portion 212. This integrated design ensures a strong and airtight connection between the fixing portion 217 and the sleeve portion 212, providing a solid foundation for the entire sealing structure and reducing the risk of leakage due to loose connections.

[0069] The connecting sleeve 218 is another component of the mounting part 213, designed to be fitted onto the end of the fixing part 217 away from the sleeve part 212. The function of the connecting sleeve 218 is to cooperate with the fixing part 217 to form a closed space and to provide a structure for accommodating and compressing the sealing ring 25. The connecting sleeve 218 can be fixed to the fixing part 217 by means of threaded connection, snap-fit ​​connection or welding.

[0070] The sealing groove is a recess or cavity inside the connecting sleeve 218, whose shape and size match the sealing ring 25. The function of the sealing groove is to precisely accommodate and position the sealing ring 25, preventing it from shifting or deforming under pressure or movement, thus ensuring the stability of the sealing effect. The sealing ring 25 is installed in the sealing groove and fills the mating gap through its own elastic deformation, achieving dynamic or static sealing. The end of the fixing part 217 refers to a specific surface or structure on the fixing part 217 that mates with the connecting sleeve 218 and applies pressure to the sealing ring 25. This end mechanically presses the sealing ring 25 into the sealing groove, ensuring that the sealing ring 25 remains tightly fitted during operation, preventing loosening or detachment, thereby maintaining the reliability of the seal.

[0071] By optimizing the structural design of the mounting part 213, the secure installation of the sealing ring 25 is ensured, thereby effectively solving the sealing reliability problem. The mounting part 213 is designed to include a fixing part 217 and a connecting sleeve 218. The fixing part 217 is integrally formed with the sleeve part 212, providing an extremely stable base for the entire sealing assembly and effectively avoiding loosening and gaps that may occur with traditional connection methods. Based on this, the connecting sleeve 218 is fitted onto the end of the fixing part 217 away from the sleeve part 212 and has a precise sealing groove inside. The sealing ring 25 is installed in this sealing groove, its position effectively defined, preventing lateral or radial displacement. The end of the fixing part 217 can press the sealing ring 25 into the sealing groove. This pressing mechanism applies continuous and uniform pressure to the sealing ring 25, making it tightly fit against the sealing groove wall. Even under frequent reciprocating motion of the moving part 22 or pressure fluctuations within the system, the sealing ring 25 can maintain its original installation state and sealing performance. With this structure, the sealing fit between the sealing ring 25 and the moving part 22 can be maintained stably for a long time, thereby ensuring the integrity of the closed space formed by the dispensing container 10, the sleeve part 212 and the moving channel 211, and effectively preventing the leakage of particulate materials or the intrusion of external impurities.

[0072] For example, such as Figure 5 As shown, the ingredient container 10 includes a receiving portion 12, a connecting portion 13, and a discharging portion 14 connected sequentially from top to bottom. The receiving portion 12 is connected to the connecting portion 13, and the connecting portion 13 is connected to the discharging portion 14. The discharging port 11 is opened at the bottom of the discharging portion 14. The receiving portion 12 and the connecting portion 13 are detachably connected, and the connecting portion 13 and the discharging portion 14 are detachably connected. The opening adjustment mechanism 20 is installed on the discharging portion 14.

[0073] The mixing container 10 is designed to consist of three independent and connectable parts, which respectively serve the functions of material containment, transfer, and discharge, and are arranged in a top-to-bottom order. This segmented design facilitates modular production, transportation, and maintenance, while also providing a basis for subsequent detachable connections. The containing part 12 communicates with the connecting part 13, and the connecting part 13 communicates with the discharging part 14, aiming to ensure that particulate material can flow smoothly from the top (containing part 12) to the middle (connecting part 13), then to the bottom (discharging part 14), and finally to the discharge port 11 inside the mixing container 10.

[0074] The connection interfaces between the various parts can be designed as open or have sufficiently large through holes to ensure the free flow of materials and avoid obstruction; alternatively, the internal structure can be designed as conical or funnel-shaped to guide the material downwards and reduce material retention at the connection points. The main channel for the discharge of particulate material from the batching container 10 is clearly defined at the bottom discharge section 14. The discharge port 11 can be a circular, square, or other shaped opening, the size of which is preset according to the required discharge speed and material characteristics, and its edges can be chamfered or smoothed to reduce the risk of material adhering to the walls or causing blockage.

[0075] The components of the mixing container 10 are not permanently fixed together, but can be separated and reassembled in some way. For example, bolted flange connections can be used, with bolts and gaskets tightly connecting the parts, allowing for disassembly by unscrewing the bolts when needed; or quick-release clamp connections can be used, enabling rapid loading and unloading of components through the quick locking and releasing mechanism of the clamps; or threaded connections can be used, achieving connection and disassembly through the threaded engagement between the components. This allows users to easily clean the inside of the container or replace components.

[0076] The mechanism for controlling the opening of the discharge port 11 is fixed to the bottom part of the batching container 10. The opening adjustment mechanism 20 can be firmly fixed to the outside or inside of the discharge section 14 by means of bolts, welding or clips, and its installation position should ensure that the flexible valve plate 23 of the opening adjustment mechanism 20 can effectively cover and adjust the discharge port 11.

[0077] By designing the mixing container 10 as a detachable modular structure and combining it with the opening adjustment mechanism 20, precise dispensing and convenient maintenance of granular materials are achieved. Specifically, the granular material is first loaded into the receiving part 12 of the mixing container 10, and then, under the action of gravity, flows smoothly through the connecting part 13 to the discharge part 14 located at the bottom. At the bottom of the discharge part 14, there is a discharge port 11 for material discharge. This detachable container structure allows the various parts of the mixing container 10 to be easily separated, greatly facilitating the cleaning and maintenance of the container's interior and effectively avoiding problems such as material residue, cross-contamination, and blockages found in traditional fixed-structure containers. By ensuring the cleanliness and unobstructed flow inside the container, the opening adjustment mechanism 20 can more stably and accurately control the material flow rate, thereby improving the accuracy and uniformity of dispensing. The opening adjustment mechanism 20 is directly installed on the discharge part 14, ensuring that the adjustment action directly affects the discharge port 11, further enhancing the precision of control.

[0078] The present invention also proposes a particulate matter batching device, which includes a particulate matter batching apparatus. The specific structure of the particulate matter batching apparatus is as described in the above embodiments. Since the particulate matter batching device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0079] Particulate matter batching equipment refers to industrial equipment used for the precise metering, dispensing, or mixing of granular materials. This equipment can be a standalone automated workstation, integrating material storage, conveying, metering, and control systems to achieve automated batching operations for granular materials. Alternatively, particulate matter batching equipment can be a module within a production line, working collaboratively with other production units (such as mixers and packaging machines) to form a complete production process.

[0080] A particulate matter batching device is a core component used to control the flow rate of particulate materials and the opening degree of the discharge port. This device can be integrated into the batching equipment as a standalone, replaceable module via mechanical or flange connections for easy maintenance and replacement. Alternatively, the particulate matter batching device can be part of the main structure of the batching equipment, formed integrally with the main body through welding or casting to improve the overall integrity and stability of the structure.

[0081] As a carrier and operating platform, the particulate batching equipment provides the necessary material storage, conveying, and control environment for the particulate batching device. The particulate batching device's internal opening adjustment mechanism 20, for example through the cooperation of the moving part 22 and the flexible valve plate 23, can achieve stepless adjustment of the discharge port 11. When this device is integrated into the batching equipment, the batching equipment can be equipped with a corresponding control system. This control system can precisely instruct the opening adjustment mechanism 20 of the particulate batching device to operate according to preset batching parameters or real-time feedback (such as material weight and flow rate).

[0082] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
