Description

Technical Field

[0001] This utility model relates to the field of material conveying and quantitative distribution technology, specifically to a marble quantitative feeding mechanism. Background Technology

[0002] In industries that require handling large quantities of marbles, such as toy manufacturing, gaming equipment, and precision counting, automated quantitative feeding mechanisms are typically used. A common quantitative feeding mechanism usually consists of a storage bin for storing marbles and a picking device that quantitatively extracts marbles from the bottom or side of the storage bin. After the picking device lifts the measured number of marbles to the discharge port, the marbles slide down to the downstream receiving station or processing equipment under gravity.

[0003] However, this type of existing technology has a significant production management problem: when a batch of marbles in the storage hopper is about to run out and a new batch needs to be added, the entire feeding and subsequent production process must be stopped. Otherwise, adding new marbles while the equipment is running will result in a mixture of old and new batches in the storage hopper. This is unacceptable for applications that require strict quality traceability, batch management, or prevention of mixing of marbles of different materials and colors. Frequent downtime for material changes will also severely impact production efficiency and continuity.

[0004] Therefore, there is an urgent need for an improved marble feeding mechanism that can achieve continuous production without stopping the machine while ensuring that different batches of marbles do not mix. That is, when replenishing a new batch of marbles, there is no need to stop supplying marbles to the downstream. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a quantitative feeding mechanism for marbles. By adding a pipeline system with buffering and control functions downstream of the feeding port, it can achieve the goal of not stopping the machine when changing batches of marbles and can strictly prevent the mixing of different batches of marbles.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A quantitative feeding mechanism for marbles includes a storage bin, a material-retrieving component disposed within the storage bin, and a vertical drive component for driving the material-retrieving component to move up and down. The upper side wall of the storage bin is provided with a material-retrieving port. The mechanism also includes: A pipe, one end of which is connected to the material inlet; The receiving hopper is connected to the other end of the pipeline; A material-blocking valve and a material-blocking drive component for controlling the opening and closing of the material-blocking valve are installed at the inlet of the pipeline; A pusher device is installed at the junction of the pipe and the receiving bin to control the number of marbles falling into the receiving bin.

[0007] In the aforementioned quantitative feeding mechanism for marbles, the bottom surface of the storage bin is provided with a slot for the material handling component to rise and pass through.

[0008] In the aforementioned quantitative feeding mechanism for marbles, the upper part of the feeding component is provided with a long strip-shaped feeding groove, and the cross-section of the feeding groove is V-shaped or arc-shaped.

[0009] In the aforementioned quantitative feeding mechanism for marbles, the feeding component is in the shape of a vertical plate, and the feeding groove is located on the top surface of the feeding component.

[0010] In the aforementioned quantitative feeding mechanism for marbles, the feeding trough is inclined relative to the horizontal plane, and the horizontal height of the end of the feeding trough near the feeding port is lower than the horizontal height of the end away from the feeding port.

[0011] In the aforementioned quantitative feeding mechanism for marbles, the bottom surface of the storage bin is inclined toward the location of the material taking component.

[0012] In the above-mentioned quantitative feeding mechanism for marbles, the bottom surface of the storage bin is an inclined surface with one side higher than the other, and the picking component is located on the lower side of the inclined surface; or, the bottom cross-section of the storage bin is V-shaped, and the picking component is located at the lowest point of the V-shaped bottom surface.

[0013] In the aforementioned quantitative feeding mechanism for marbles, the pushing device includes a pushing drive and a pushing component that is driven by the pushing drive to move in a straight line. The pushing component has a through hole with a diameter equivalent to that of a single marble, and the direction of movement of the pushing component is perpendicular to the trajectory of the marble falling from the pipe into the receiving bin.

[0014] In the aforementioned marble metering feeding mechanism, a first sensor for sensing whether there are marbles inside the pipe is provided at the outlet of the pipe.

[0015] In the aforementioned marble quantitative feeding mechanism, a second sensor is provided at one end of the pipe near the feeding port to sense whether there are too many marbles in the pipe.

[0016] Compared with the prior art, the advantages of this utility model are: The added pipeline is not only a conveying channel but also a buffer container, temporarily storing the previous batch of marbles removed from the storage silo. A material-blocking valve is controlled by a material-blocking actuator. When closed, the valve acts as a reliable physical barrier, completely isolating the storage silo being replenished with new material from the pipeline containing old material. This allows the processes of adding material to the storage silo and supplying material to the downstream receiving silo to occur simultaneously and independently, eliminating the fundamental reason for downtime during material changes. A pusher device at the pipeline outlet quantitatively releases the marbles buffered in the pipeline. Even if the supply to the storage silo is temporarily interrupted due to material changes, the pusher device can still systematically and quantitatively output the buffered marbles to the receiving silo according to a preset quantity, thus ensuring continuous production and accurate control of the supply quantity.

[0017] Furthermore, the bottom surface of the storage bin is provided with a slot for the material-retrieving component to rise and pass through. The material-retrieving component moves up and down within the slot, ensuring the verticality and stability of its movement trajectory and preventing swaying during the upward movement of the ball, thereby ensuring that the material-retrieving slot always accurately aligns with the material-retrieving port.

[0018] Furthermore, the upper part of the material-receiving component is provided with an elongated material-receiving groove, the cross-section of which is V-shaped or arc-shaped. This elongated groove structure predetermines a unique, linear path and position for loading the marbles. The V-shaped or arc-shaped cross-section perfectly matches the geometry of the spherical marbles. When the marbles roll into the groove, they automatically position themselves at the lowest point of the groove bottom under gravity and naturally arrange themselves in a straight line along the length of the groove. This process is spontaneous and deterministic, requiring no external control or adjustment.

[0019] Furthermore, the material-receiving component is in the shape of an upright plate, and the material-receiving groove is formed on the top surface of the material-receiving component. The plate-like structure provides the material-receiving component with high bending stiffness when pushing a row of marbles upward, ensuring that it will not bend or deform under force, thereby ensuring the precise position of the material-receiving groove and accurate docking with the material-receiving port. This shape is also suitable for sliding up and down in the slots or guide rails of the storage bin, and has good self-guiding properties.

[0020] Furthermore, the material receiving trough is inclined relative to the horizontal plane, with the horizontal height of the end of the trough near the material receiving port being lower than the horizontal height of the end away from the material receiving port. When the material receiving component rises to align with the material receiving port, the inclined trough naturally forms a gravity slide. Under the influence of gravity, the marble inevitably, automatically, and sequentially rolls from the high end towards the low end of the material receiving port. This process does not rely on any sensors, actuators, or control logic, eliminating the risk of unloading failure due to electrical faults, signal delays, or mechanical jamming, achieving near-absolute reliability.

[0021] Furthermore, the bottom surface of the storage bin is inclined toward the location of the picking component. The inclined bottom surface utilizes gravity as a permanent, maintenance-free driving force, allowing the marbles in all areas of the storage bin to automatically and continuously slide toward the lowest point where the picking component is located and converge.

[0022] Furthermore, the bottom surface of the storage silo is a slope with one side higher than the other, and the material picker is located on the lower side of the slope; or, the bottom cross-section of the storage silo is V-shaped, and the material picker is located at the lowest point of the V-shaped bottom surface. The unidirectional slope design allows the lowest side of the slope to combine with the vertical sidewall, naturally forming a corner or recessed area. The marbles gather here and are not easily scattered due to slight shaking of the equipment, providing the material picker with a loading area where the material is highly concentrated and in a constant position; the symmetrical structure of the V-shaped bottom surface allows the marbles to converge symmetrically from both sides of the storage silo towards the lowest center line, which eliminates the dead corners that may exist at the far end of the unidirectional slope, achieving the most uniform and thorough material collection and emptying.

[0023] Furthermore, the feeding device includes a feeding drive and a feeding component that moves linearly driven by the feeding drive. The feeding component has a through hole with a diameter equivalent to that of a single marble. The movement direction of the feeding component is perpendicular to the trajectory of the marble falling from the pipe into the receiving bin. By setting the linear movement direction of the feeding component to be perpendicular to the falling trajectory of the marble, the feeding component does not need to bear the gravitational impact of the falling marble, but only needs to overcome a small sliding friction force. Although the number of marbles released in a single action is fixed, the total number of materials fed each time and the feeding rhythm can be flexibly set in the program by controlling the operating frequency and total number of actions of the feeding drive.

[0024] Furthermore, a first sensor is installed at the outlet of the pipeline to detect the presence of marbles within the pipeline. This first sensor directly monitors the presence of marbles at the pipeline outlet. When it detects no marbles, this is a definitive physical signal indicating that the last marble of the previous batch has been consumed. This provides the control system with the unique and most accurate trigger condition to open the material-blocking valve and begin supplying a new batch of marbles. It replaces the crude method of calculating based on running time or manual estimation, ensuring that the batch switching action is neither too early nor too late to prevent production interruptions, achieving zero error in switching timing.

[0025] Furthermore, a second sensor is installed at the end of the pipe near the feed inlet to detect whether there are too many marbles inside the pipe. The core function of the second sensor is to monitor the level of the marbles inside the pipe and issue a warning signal before it reaches full capacity. This allows the system to proactively suspend upstream feed and take-up operations before a physical blockage actually occurs. Attached Figure Description

Detailed Implementation

[0028] A quantitative feeding mechanism for marbles includes a storage bin 100, a material-picking component 200 disposed within the storage bin 100, and a vertical drive component 300 for driving the material-picking component 200 to move up and down. The upper side wall of the storage bin 100 is provided with a material-picking port 120. The mechanism also includes: Pipe 400, one end of which is connected to the material inlet 120; The receiving hopper 500 is connected to the other end of the pipe 400; The material blocking valve 600 and the material blocking drive component 700 that controls the opening and closing of the material blocking valve 600 are disposed at the inlet of the pipeline 400. The pusher device 800 is located at the junction of the pipe 400 and the receiving bin 500, and is used to control the number of marbles falling into the receiving bin 500.

[0029] The added pipe 400 is not only a conveying channel but also a buffer container, temporarily storing the previous batch of marbles taken from the storage silo 100. The material-blocking valve 600 is controlled by the material-blocking drive 700. When the material-blocking valve 600 is closed, it acts as a reliable physical barrier, completely isolating the storage silo 100, which is being replenished with new material, from the pipe 400, which contains old material. This allows the processes of adding material to the storage silo 100 and supplying material from the pipe 400 to the downstream receiving silo 500 to be carried out simultaneously and independently, thus eliminating the fundamental reason for stopping production during material changes. The pusher device 800 installed at the outlet of the pipe 400 can quantitatively release the marbles buffered in the pipe 400. Even if the supply in the storage silo 100 is temporarily interrupted due to material changes, the pusher device 800 can still orderly and quantitatively output the marbles buffered in the pipe 400 to the receiving silo 500 according to a preset quantity, thereby ensuring continuous production and accurate control of the supply quantity.

[0030] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] In order to facilitate traceability, different batches of materials are not allowed to be mixed during the production of some products. Therefore, the next batch of marbles can only be used after a batch of marbles has been completely used up. However, the existing marble feeding device requires the previous batch of marbles to be used up before the next batch of marbles can be added. This will force the machine to stop and wait, resulting in a decrease in production efficiency. This solution is mainly used to solve the above-mentioned technical problems.

[0035] See Figures 1 to 6 This invention relates to a quantitative feeding mechanism for marbles. The mechanism includes a frame with a storage bin 100 at the top for storing marbles. To facilitate adding marbles to the storage bin 100, it is designed with an open top and a cover 130 at the opening. The cover 130 can be locked to prevent accidental addition of marbles from other batches. The storage bin 100 contains a picking component 200, and the frame is equipped with a vertical drive component 300 that drives the picking component 200 to move up and down. Specifically, the vertical drive component 300 drives the picking component 200 to move upwards to pick up a certain amount of marbles and deliver them out of the storage bin 100. Correspondingly, a material inlet 120 is provided on the upper side wall of the storage bin 100. After the material picker 200 picks up a certain amount of marbles, it rises to the material inlet 120, so that the marbles are sent out of the storage bin 100 from the material inlet 120. Correspondingly, the number of marbles added into the storage bin 100 at one time should be lower than the horizontal height of the material inlet 120.

[0036] In this embodiment, a pipe 400 and a receiving bin 500 are also added. The pipe 400 is located between the feeding port 120 and the receiving bin 500. The receiving bin 500 stores a fixed quantity of marbles according to the number of marbles to be retrieved each time, making it convenient for operators to handle. At the inlet of the pipe 400, a material-blocking valve 600 and a material-blocking drive component 700 are installed to control the opening and closing of the material-blocking valve 600. When the next batch of marbles needs to be added, the material-blocking drive component 700 controls the material-blocking valve 600 to close the pipe 400, preventing the two batches of marbles from mixing before all the previous batch of marbles has been retrieved. A pushing device 800 is also provided at the junction of the pipe 400 and the receiving bin 500. The pushing device 800 can control the number of marbles falling into the receiving bin 500, allowing operators to control the number of marbles stored in the receiving bin 500 each time as needed.

[0037] With the above setup, pipe 400 is no longer just a conveying channel; its core function is as a buffer container, temporarily storing the previous batch of marbles that have been taken from storage silo 100. When the material blocking valve 600 is closed, it becomes a reliable physical barrier, completely isolating storage silo 100, which is being replenished with new material, from pipe 400, which is buffering old material. This allows the processes of "adding material to storage silo 100" and "supplying material from pipe 400 to downstream receiving silo 500" to be carried out simultaneously and independently, thus eliminating the need to stop production for material changes. Even if the supply to storage silo 100 is temporarily interrupted due to material changes (material blocking valve 600 is closed), the pushing device 800 can still orderly and quantitatively output the existing marbles in the buffer area of ​​pipe 400 to receiving silo 500 according to the preset quantity, thereby ensuring continuous and uninterrupted production rhythm and accurate and controllable supply quantity.

[0038] Furthermore, the bottom surface of the storage bin 100 has a slot 110 through which the material-retrieving component 200 ascends. The slot 110 itself constitutes a natural guiding mechanism. The material-retrieving component 200 moves up and down within the slot 110, ensuring the verticality and stability of its movement trajectory and preventing swaying during the upward movement of the ball, thereby ensuring that the material-retrieving slot 210 always accurately aligns with the material-retrieving port 120. At the same time, the vertical drive component 300 can be stably installed directly below the storage bin 100, directly pushing the material-retrieving component 200, resulting in the shortest force transmission path and the most stable structure. If the slot 110 on the bottom surface of the storage bin 100 is not used, and an internal guiding mechanism is used to guide the vertical movement of the material-retrieving component 200, it will occupy the internal space of the storage bin 100; while if the slot 110 is cut on the side of the storage bin 100 for the material-retrieving component 200 to insert, a more complex structure is required to achieve the vertical movement of the material-retrieving component 200.

[0039] A long, narrow feeding groove 210 is provided at the upper part of the feeding component 200. The cross-section of the feeding groove 210 is V-shaped or arc-shaped. The long, narrow groove structure provides a unique, linear path and position for loading the marbles. The V-shaped or arc-shaped cross-section design perfectly matches the geometry of the spherical marbles. When the marbles roll into the groove, they will automatically position themselves at the lowest point of the groove bottom under the action of gravity, and naturally arrange themselves in a straight line along the length of the groove. This facilitates the orderly passage of the marbles from the feeding groove 210 through the feeding port 120.

[0040] Furthermore, the material-receiving component 200 is in the shape of an upright plate, and the material-receiving groove 210 is opened on the top surface of the material-receiving component 200. The plate-shaped material-receiving component 200 structure not only ensures that the material-receiving component 200 has extremely high bending stiffness when lifting the ball, ensuring that it will not bend or deform, but also the material-receiving component 200 cooperates with the groove wall of the groove 110, making it difficult for gaps to form between the material-receiving component 200 and the groove wall, which would cause the ball to get stuck, thus ensuring the smooth operation of the material-receiving component 200 in the vertical direction.

[0041] To ensure the smooth and natural sliding of the balls on the picking component 200 from the picking groove 210 into the picking port 120, the picking groove 210 is designed to be inclined. This means the horizontal height of the end of the picking groove 210 near the picking port 120 is lower than the horizontal height of the end away from the picking port 120. When the picking component 200 rises to align with the picking port 120, the inclined picking groove 210 naturally forms a gravity slide. Under the influence of gravity, the balls inevitably, automatically, and sequentially roll from the higher end to the lower end of the picking port 120 until the picking groove 210 is completely emptied, ensuring the complete delivery of the picking quantity each time. Furthermore, this is a purely mechanical rolling process, operating quietly without impact, vibration, or noise. This process does not rely on any sensors, actuators, or control logic, eliminating the risk of unloading failure due to electrical faults, signal delays, or mechanical jamming, achieving near-absolute reliability.

[0042] Based on the above embodiments, to ensure that all marbles in the storage bin 100 can enter the picking slot 210, the bottom surface of the storage bin 100 can be tilted towards the location of the picking component 200. The tilted bottom surface utilizes gravity as a permanent, maintenance-free driving force, allowing marbles in all areas of the storage bin 100 to automatically and continuously slide towards the lowest point of the picking component 200 and converge. This completely replaces the mechanical auger, vibrator, or pneumatic feeding device that may need to be installed separately, eliminating additional energy consumption, noise, wear, and corresponding control circuits and failure points, achieving extreme simplification of the supply side. Furthermore, this design ensures that the picking component 200 automatically fills with marbles each time it descends to its position, effectively preventing the picking slot 210 from being empty or not filled due to the dispersion or uneven accumulation of marbles.

[0043] The specific bottom structure of the storage silo 100 includes, but is not limited to, the following options: One design features a sloping bottom surface of the storage bin 100, with the slot 110 located on the lower side of the slope. This means the material handling component 200 is situated on the lower side of the slope. This is the simplest form for achieving the tilting and collecting function, with a simple manufacturing process and lowest cost. It is particularly suitable for equipment layouts with limited lateral space, allowing the feeding direction to be arranged parallel to the main axis of the equipment, resulting in a very compact overall structure. The lowest side of the slope, combined with the vertical sidewall, naturally forms a corner or recessed area where the balls are collected and less likely to scatter due to slight equipment movement. This provides the material handling component 200 with a highly concentrated and consistently positioned loading area, further enhancing the reliability of material handling.

[0044] Another design features a V-shaped cross-section at the bottom of the storage silo 100, with the slot 110 located at the lowest point of the V-shaped bottom, where the material handling component 200 is also situated. This V-shaped design is a symmetrical structure, allowing the balls to converge symmetrically from both sides of the storage silo 100 towards the lowest central line. This eliminates the potential dead zones at the far ends of a unidirectional inclined plane, achieving the most uniform and thorough material collection and emptying. Unlike a unidirectional inclined plane where materials converge in only one direction, the V-shaped bottom has two inclined surfaces, guiding the balls to the center line from two directions, thus improving collection efficiency.

[0045] Based on the above embodiments, the feeding device 800 includes a feeding seat 830, a feeding drive 810, and a feeding member 820 driven by the feeding drive 810 to move linearly. The feeding seat 830 has a vertically connected material leakage channel 840 and a horizontally connected material feeding channel 850. One end of the material leakage channel 840 is connected to the pipe 400, and the other end is connected to the receiving bin 500. However, the material leakage channel 840 located above the material feeding channel 850 is different from the material feeding channel 850 located above the material feeding channel 850. The lower discharge channel 840 has a non-aligned axis, while the pusher channel 850 restricts the movement trajectory of the pusher 820. The pusher 820 has a through hole 821 with a diameter equivalent to a single marble. Only when the through hole 821 aligns with the discharge channel 840 above the pusher channel 850 will the marble fall into the through hole, and then the pusher 820 will be pushed to align with the discharge channel 840 below the pusher channel 850, allowing the marble to fall into the receiving bin 500. If the through hole 821 is not aligned with the discharge channel 840, the discharge channel 840 is blocked by the pusher 820 and is cut off. The pusher device 800 with the above structure releases a fixed number of marbles (e.g., one marble) with each reciprocating linear motion. This metering method does not rely on complex electronic counting but is guaranteed by mechanical dimensions, achieving physical limits of accuracy and absolute reliability.

[0046] In addition, to accurately sense the status of the marbles within the pipe 400 and facilitate precise control of the opening and closing of the material blocking valve 600, a first sensor 910 is installed at the outlet of the pipe 400 to detect the presence of marbles within the pipe 400, and a second sensor 920 is installed at the end of the pipe 400 near the feed inlet 120 to detect whether there are too many marbles within the pipe 400. The first sensor 910 directly monitors the presence of marbles at the outlet of the pipe 400. When it detects "no marbles," this is a definitive physical signal indicating that the last marble of the previous batch has been consumed. This provides the control system with the unique and most accurate trigger condition to open the material blocking valve 600 and begin feeding a new batch of marbles. The core function of the second sensor 920 is to monitor the level of marbles within the pipe 400 and issue a warning signal before it reaches full capacity (which may block the feed inlet 120 or affect flow). This allows the system to proactively suspend upstream material feeding and receiving operations before a physical blockage actually occurs.

[0047] During normal material handling, the vertical drive 300 lifts the material handling component 200 upwards. During this process, the material handling trough 210 at the top of the material handling component 200 carries a row of marbles upwards. When one end of the material handling trough 210 aligns with the material handling port 120, the marbles pass through the material handling port 120 by gravity and enter the pipe 400. The pushing device 800 then releases a corresponding number of marbles into the receiving bin 500 according to a set quantity. The receiving bin 500 has a door 510 to prevent marbles from falling out. After releasing enough marbles, the pushing device 800 stops, and the operator can open the door 510 to retrieve the marbles. The material handling component 200 continuously replenishes marbles into the pipe 400 until the second sensor 920 detects an excess of marbles in the pipe 400 and sends a signal. The control system then controls the vertical drive 300 to stop operating for a period of time, allowing some marbles in the pipe 400 to be released before resuming operation. If a batch of marbles runs out and needs to be replenished, the cover plate 130 on top of the storage bin 100 is opened. At this time, the material blocking drive 700 drives the material blocking valve 600 to close the inlet of the pipe 400. When replenishing a new batch of marbles into the storage bin 100, the pushing device 800 can continue to replenish marbles into the receiving bin 500 until the first sensor 910 detects that there are no marbles in the pipe 400 and sends a signal to the control system. The control system controls the material blocking drive 700 to start, which drives the material blocking valve 600 to open, allowing a new batch of marbles to enter the pipe 400.

[0048] Through a collaborative system of inclined hopper, V-shaped feeding chute 210, buffer pipe 400, barrier valve, and quantitative feeding, this system creatively achieves a balance between production continuity and absolute batch purity in quantitative marble feeding: the inclined hopper and feeding chute 210 ensure stable and precise single-row extraction of marbles; the buffer pipe 400, serving as a temporary storage area, in conjunction with the inlet barrier valve 600, allows for the safe filling of new batches while emptying old batches of marbles, achieving physical isolation and seamless connection; the feeding device 800 and sensors at the outlet ensure a continuous, quantitative, and controllable supply downstream. With its simple mechanical structure and intelligent control, the entire system fundamentally solves the industry problem of traditional equipment requiring downtime for material changes and the resulting batch mixing, significantly improving production efficiency and quality management.

[0049] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
