Description

[0001] The present invention proposes a discharge device. The discharge device comprises: a frame; a discharge component arranged on the frame, comprising a discharge container as well as a feed opening, a first discharge pipe and a second discharge pipe, all of which are connected to the interior of the discharge container, wherein a discharge area of ​​the first discharge pipe is smaller than a discharge area of ​​the second discharge pipe;A discharge component comprising a valve seat and a material transfer disc, wherein the valve seat is connected to the discharge container and the component has an installation space as well as a first feed channel, a second feed channel and a discharge channel, all of which are connected to the installation space, wherein the first feed channel is connected to the first discharge channel and the second feed channel is connected to the second discharge channel, the material transfer disc is movably arranged in the installation space, and several discharge channels are arranged at intervals on the material transfer disc, wherein the first feed channel and the second feed channel can be selectively connected to any two of the several discharge channels. The technical solution of the present invention solves the problem of the low material discharge accuracy of the material discharge device according to the prior art. TECHNICAL AREA

[0002] The present invention relates to the technical field of material handling, in particular a material discharge device. STATE OF THE ART

[0003] As an important mechanism for conveying powdered or granular materials, the discharge device is widely used in dosing machines. Powders can be classified as either free-flowing or poorly flowing depending on their flowability. For free-flowing powders, one suitable discharge device is to position the screw rod vertically in the conveying channel. This allows the material's own weight to be used to ensure smoother discharge. The conveying process of the existing discharge device is controlled by adjusting the material volume.

[0004] However, with granular or powdered materials, this is influenced by many factors that alter the weight per unit volume. For example, there is an unfilled space between the particles of granular materials and an unfilled space between the particles of powdered materials. These spaces change with the position and state of the materials. Since the particle size of powdered and granular materials differs (the particle size of granular materials is larger than that of powdered materials), the unfilled space between the particles of granular materials and the unfilled space between the particles of powdered materials also typically differ. In this context, the dispensing device may struggle to release the material according to the set volume, resulting in reduced material dispensing precision.

[0005] In the prior art, the discharge device is additionally equipped with a weight sensor to monitor and control the discharge process, thus solving the problem of the discharge device's low discharge precision. However, granular or powdered materials flow due to their own weight in the final stage of material discharge, leading to a degree of uncontrollability. It is difficult to effectively improve the material discharge precision through feedback from the weight sensor and control. SUMMARY OF THE INVENTION

These multiple signal outputs are arranged correspondingly to multiple discharge channels.

[0013] The discharge component further comprises: a first drive element arranged on the frame; a first rotary shaft rotatably mounted in the discharge hopper. One end of the first rotary shaft is driven by an output shaft of the first drive element, while the other end of the first rotary shaft is provided with a discharge component that projects into the first discharge pipe.

[0020] It should be noted that the embodiments and features of the embodiments of the present application can be combined with one another, provided there are no conflicts. The present invention is described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] As in Fig. 1 to Fig. Figure 18 illustrates embodiments of the present invention as a discharge device. The discharge device comprises a frame 10; a discharge component arranged on the frame 10, comprising a discharge container 21 and a feed opening 22, a first discharge pipe 23 and a second discharge pipe 24, wherein the feed opening, the first discharge pipe and the second discharge pipe are connected to the interior of the discharge container 21, and wherein a discharge area of ​​the first discharge pipe 23 is smaller than that of the second discharge pipe 24; a discharge component comprising a valve seat 30 and a material transfer disc 41. The valve seat 30 is connected to the discharge container 21. The valve seat 30 has an installation space as well as a first feed channel 31, a second feed channel 32 and a discharge channel 33, wherein the first feed channel, the second feed channel and the discharge channel are all connected to the installation space.The first feed channel 31 is connected to the first discharge pipe 23, and the second feed channel 32 is connected to the second discharge pipe 24. The material transfer disc 41 is movably arranged in the installation space. Several discharge channels 42 are arranged at intervals on the material transfer disc 41. The first feed channel 31 and the second feed channel 32 can be selectively connected to any two of the discharge channels 42. The discharge channel 33 is provided corresponding to the first feed channel 31. The discharge channel 33 and the first feed channel 31 are located on both sides of the material transfer disc 41 along one direction of extension of the discharge channel 42.

[0022] In the above technical solution, large quantities of material can be discharged quickly from the second discharge pipe 24, and small quantities of material can be discharged in a fine manner from the first discharge pipe 23, because the discharge area of ​​the first discharge pipe 23 is smaller than that of the second discharge pipe 24. When material discharge is required, the necessary quantity can be provided quickly because the second discharge pipe 24 has a relatively large discharge area. In the initial phase, the material transfer disc 41 can be moved to a position where the second feed channel 32 is connected to one of the several discharge channels 42, allowing the material to enter this discharge channel 42. Subsequently, the material transfer disc 41 is moved so that the discharge channel 42, now filled with material, moves to a position where it is connected to the discharge channel 33.In this way, the material can be transferred multiple times using the material transfer disc 41, enabling efficient and rapid material discharge. Furthermore, the volume of the discharge channel is fixed; that is, each discharge channel transports a specific quantity of material each time, allowing for precise control of the total amount of material discharged. Shortly before the material discharge is complete, the material transfer disc 41 is in a position where the first feed channel 31 and the discharge channel 33 are connected by one of the multiple discharge channels 42. The first discharge pipe 23 can be connected to the discharge channel 33 via the first feed channel 31 and the discharge channel 42. The first discharge pipe 23 has a smaller discharge area, which allows for effective control of the material flow rate, thus enabling micro-fine material discharge.In this way, by controlling the movement position of the material transfer disc 41, it is possible to flexibly select whether the material is discharged through the first discharge tube 23 or through the second discharge tube 24. This achieves a fast and precise discharge, which improves the accuracy of the material discharge.

[0023] It should be noted that in the embodiments of the present invention, powdered materials generally refer to very fine particles in powder form, the particle size of which ranges from micrometers to several dozen micrometers. Granular materials refer to an accumulation of larger particles, the particle size of which is generally between a few hundred micrometers and several millimeters.

[0024] In the exemplary embodiments of the present invention, the feed opening 22 is preferably located above the first discharge pipe 23 and the second discharge pipe 24, so that the material from the feed opening 22 enters the storage tray 25 and falls by gravity into the first discharge pipe 23 and the second discharge pipe 24.

[0025] In the embodiments of the present invention, preferably four discharge channels 42 are provided, which are evenly spaced around the axis of rotation of the material transfer disk 41.

[0026] In the exemplary embodiments of the present invention, the material transfer disc 41 is preferably rotatably arranged in the installation space. Several discharge channels 42 are spaced apart around the axis of rotation of the material transfer disc.

[0027] In one embodiment, the material transfer disc 41 can also be movably arranged in the installation space and moved by horizontal pushing and pulling. The number of discharge channels on the material transfer disc 41 is preferably two.

[0028] As in Fig. 4 to Fig. As shown in Figure 7, the discharge component in the embodiments of the present invention further comprises: a first valve disc 43 on which two first channels 44 are arranged; a second valve disc 45 on which a second channel 46 is arranged. Along the axis of rotation (along the direction of extension of the discharge channel 42), the first valve disc 43 and the second valve disc 45 are each pressed against both sides of the material transfer disc 41. The two first channels 44 are each connected to the first feed channel 31 and the second feed channel 32 respectively, and the second channel 46 is connected to the discharge channel 33 accordingly.

[0029] In the technical solution described above, the first valve disc 43 and the second valve disc 45 are each arranged on both sides of the material transfer disc 41 and are in an interference fit with this material transfer disc 41. This ensures that the first valve disc 43 and the second valve disc 45 fit tightly against the material transfer disc 41. This effectively prevents powder from escaping into the space between the valve discs and guarantees the sealing and accuracy of the discharge process.

[0030] In the exemplary embodiments of the present invention, the two first channels 44 are each connected to the first feed channel 31 and the second feed channel 32, respectively. When the discharge device is in the fine metering state, the material in the first feed channel 31 can pass smoothly through the first channel 44 into the discharge channel of the material transfer disc 41. When the discharge device is in the efficient rapid discharge state, the material in the second feed channel 32 can pass smoothly through the first channel 44 into the discharge channel of the material transfer disc 41.

[0031] In the exemplary embodiments of the present invention, the second channel 46 is connected to the discharge channel 33. If the material transfer disk 41 rotates such that one of the discharge channels 42 is aligned with the discharge channel 33, the material can pass from the discharge channel 42 of the material transfer disk 41 via the second channel 46 into the discharge channel 33 and be discharged via this discharge channel 33.

[0032] As in Fig. 4 and Fig. As shown in Figure 7, the discharge component in the embodiments of the present invention further comprises a first elastic element 47 located on a side of the first valve disc 43 facing away from the material transfer disc 41. One end of the first elastic element 47 rests against the material transfer disc 41 and the other end of the first elastic element 47 rests against an inner wall of the installation space; and / or, the discharge component further comprises a second elastic element 48 located on a side of the second valve disc 45 facing away from the material transfer disc 41. One end of the second elastic element 48 rests against the second valve disc 45 and the other end of the second elastic element 48 rests against an inner wall of the installation space.

[0033] Due to the arrangement described above, the first elastic element 47 and the second elastic element 48 act on the first valve disc 43 and the second valve disc 45, respectively. The elastic force ensures that the first valve disc 43 and the second valve disc 45 are always in close contact with the material transfer disc 41, thus guaranteeing a good seal during rotation. This prevents powder from escaping into the space between the two adjacent valve discs and therefore does not impair the discharge accuracy. However, during prolonged operation of the system, the contact between the first valve disc 43 and the second valve disc 45 and the material transfer disc 41 can become leaky due to wear. The first elastic element 47 and the second elastic element 48 can provide a certain compensating force.Even after wear of the valve disc, the seal between the two adjacent valve blades remains guaranteed, thus extending the service life and maintenance cycle of the system.

[0034] In the exemplary embodiments of the present invention, the first elastic element 47 and the second elastic element 48 are each springs. The first elastic element 47 and the second elastic element 48 are always in a compressed state.

[0035] As in Fig. 4, Fig. 6, Fig. 9 and Fig. As shown in Figure 11, in the exemplary embodiments of the present invention, a first positioning element 49 is provided on one side of the first valve disc 43 and the valve seat 30, and a first positioning groove 50 is provided on the other side of the first valve disc 43 and the valve seat 30, wherein the first positioning element 49 and the first positioning groove 50 are precisely aligned with each other; and / or, a second positioning element 51 is provided on one side of the second valve disc 45 and the valve seat 30, and a second positioning groove 52 is provided on the other side of the second valve disc 45 and the valve seat 30, wherein the second positioning element 51 and the second positioning groove 52 are precisely aligned with each other.

[0036] The arrangement described above ensures that the interaction of the first positioning element 49 with the first positioning groove 50 and the second positioning element 51 with the second positioning groove 52 prevents the first valve disc 43 and the second valve disc 45 from rotating when the material transfer disc 41 rotates. This prevents misalignment of the first valve disc 43 and the second valve disc 45. Furthermore, it ensures that the two first channels 44 on the first valve disc 43 are each connected to the first feed channel 31 and the second feed channel 32, respectively, and that the second channel 46 on the second valve disc 45 can be connected to the discharge channel 33, thus achieving high-precision material application.

[0037] It should be noted that in the embodiments of the present invention, the first positioning element 49 merely limits the rotation of the first valve disc 43 about the axis of rotation of the material transfer disc 41, but does not restrict the movement of the first valve disc 43 along the axis of rotation of the material transfer disc 41. Likewise, the second positioning element 51 merely limits the rotation of the second valve disc 45 about the axis of rotation of the material transfer disc 41, but does not restrict the movement of the second valve disc 45 along the axis of rotation of the material transfer disc 41.

[0038] As in Fig. 4 and Fig. As shown in Figure 5, in the embodiments of the present invention, an engagement tooth is provided on an outer circumference of the material transfer disc 41. The discharge component further comprises: a drive part 71, which is arranged on the frame 10; a transmission part, which includes a gear 72 and a synchronous belt 73 arranged on the outer circumference of the gear 72 and the material transfer disc 41, wherein the gear 72 is rotatably arranged relative to the valve seat 30 and is driven by an output shaft of the drive part 71.

[0039] The rotation of the gear 72 is controlled by the drive element 71 in the arrangement described above. The material transfer disc 41 with meshing teeth can be driven to rotate by the synchronous belt 73, thus enabling the rotation of the material transfer disc 41. In this way, the use of the gear 72 and the synchronous belt 73 can improve transmission efficiency and reduce energy loss during the transmission process. The synchronous belt 73 can also ensure transmission synchronization between the material transfer disc 41 and the gear 72 to prevent slippage and wear during the transmission process, thereby improving the stability and durability of the device.

[0040] In the exemplary embodiments of the present invention, a receiving groove for receiving the gear 72 is preferably provided on the valve seat 30, in which the gear 72 is rotatably mounted. A gap exists between the gear 72 and the valve seat 30 in order not to impede the rotation of the gear 72.

[0041] In the embodiments of the present invention, the drive element 71 can preferably be a motor or another drive source. The speed and angle of the material transfer disc 41 can be adjusted electronically according to the preset program or the current material requirements to enable automatic and intelligent material transport.

[0042] In particular, the frame 10 in the exemplary embodiments of the present invention comprises, as shown in Fig. Figure 2 shows a left-hand rotary table motor plate 6 connected to the transition shell 26. The drive unit 71 is a stepper motor fixed to the rotary table motor plate 6. The output shaft of the drive unit 71 is arranged vertically downwards and is attached to the upper base 8 via a bearing. The side walls of the upper base 8 and the lower base 9 facing the gear 72 are both provided with openings. The synchronous belt 73 connects through these openings to both the gear 72 and the material transfer disc 41.

[0043] In particular, in the embodiments of the present invention, the valve seat 30 comprises an upper base 8 and a lower base 9. The upper base 8 is fastened to the lower bottom surface of the discharge tray 27 by screws. A side of the upper base 8 facing away from the lower base 9 is provided with the first feed channel 31 and the second feed channel 32. A side of the upper base 8 facing the lower base 9 is provided with an upper first valve disc groove 53 and an upper valve disc groove for material transfer, which is connected to the first valve disc groove 53. The upper wall of the first valve disc groove 53 is provided with an upper pivot groove. The first feed channel 31 and the second feed channel 32 are both connected to the first valve disc groove 53. The lower base 9 is firmly connected to the upper base 8 by screws. A side of the lower base 9 facing away from the upper base 8 is provided with a discharge channel 33.One side of the lower base 9 facing the upper base 8 is provided with a lower valve disc groove for material transfer and a second valve disc groove 54, which is connected to the lower valve disc groove for material transfer. The bottom wall of the second valve disc groove 54 is provided with a lower rotary shaft groove. The material transfer disc consists of a pivot shaft 411 and a valve disc body 412 connected to the outer circumference of the pivot shaft 411. One end of the pivot shaft 411 penetrates the first valve disc 43 and is in a rotary fit with the upper rotary shaft groove. The other end of the pivot shaft 411 penetrates the second valve disc 45 and is in a rotary fit with the lower rotary shaft groove. The first valve disc groove 53 serves to mount the first valve disc 43, and the second valve disc groove 54 serves to mount the second valve disc 45.The valve disc body 412 is mounted in a chamber formed by the upper valve disc groove for material transfer and the lower valve disc groove for material transfer. The upper rotary shaft groove, the first valve disc groove 53, the upper valve disc groove for material transfer, the lower valve disc groove for material transfer, the second valve disc groove 54, and the lower rotary shaft groove together form the installation space.

[0044] As in Fig. 4 and Fig. As shown in Figure 5, the discharge component in the embodiments of the present invention further comprises a signal output component and a signal acquisition component 74 for acquiring the signal from the signal output component. The signal output component comprises several signal outputs 75, which are arranged on the outer circumference of the output shaft of the drive part 71. The several signal outputs 75 are arranged correspondingly to several discharge channels 42.

[0045] In the above arrangement, the multiple signal outputs 75 of the signal output component are connected to the output shaft of the drive component 71. When the drive component 71 rotates the material transfer disk 41, the multiple signal outputs 75 also rotate accordingly. The signal acquisition component 74 can detect the position of each signal output 75 in real time and thus determine the angle of rotation and the position of the material transfer disk 41 in order to ascertain whether the multiple discharge channels 42 on the material transfer disk 41 are aligned with the discharge channel. This allows for precise control of the material's fall path and precise regulation of the discharge quantity.

[0046] In the embodiments of the present invention, the signal detection component 74 is preferably a sensor and the signal output is the signal output 75.

[0047] As in Fig. 2 and Fig. As shown in Figure 12, the discharge component in the embodiments of the present invention further comprises: a first drive element 81, which is arranged on the frame 10; a first rotary shaft 82, which is rotatably arranged in the discharge container 21. One end of the first rotary shaft 82 is drivenly connected to an output shaft of the first drive element 81, while the other end of the first rotary shaft 82 is provided with a discharge component 83, which projects into the first discharge tube 23. An outer circumference of the discharge component 83 is provided with a spiral conveying element, which corresponds to the inner wall of the first discharge tube 23. The spiral conveying element is arranged spirally around the discharge component 83.

[0048] The arrangement described above allows the spiral conveying element to transport the powdered or granular material downwards and to control the speed and flow rate of the material flowing through the first discharge tube 23. By controlling the speed and angle of the first rotating shaft 82 via the first drive element 81, the speed and angle of the spiral conveying element can be controlled, thereby precisely controlling the discharge quantity of the powdered or granular material from the first discharge tube 23.

[0049] It should be noted that in the embodiments of the present invention, the spiral conveying element has a spiral groove through which the powdered or granular material is conveyed downwards in a controlled manner until it exits at the rear end of the spiral groove. To control accuracy, the gap between the spiral conveying element and the inner wall of the first discharge tube 23 is relatively small (so that practically no material escapes). As in Fig. As shown in Figure 12, the discharge component in the embodiments of the present invention further comprises a first stirring element 84, which is connected to the outer circumference of the first rotating shaft 82 and is located between the two ends of the first rotating shaft 82.

[0050] The arrangement described above allows the first stirring element 84 to stir the material and convey it to the first discharge pipe 23. This prevents clumping or bridging of the material, ensures its flowability, and makes the material discharge more uniform, thus improving the consistency, continuity, and stability of the material discharge.

[0051] Preferably, the first stirring element 84 in the embodiments of the present invention is a stirring fork.

[0052] As in Fig. 2 and Fig. As shown in Figure 12, the discharge component in the embodiments of the present invention further comprises: a second drive element 91, which is arranged on the frame 10; a second rotary shaft 92, which is rotatably arranged in the discharge container 21 and is drivenly connected to the output shaft of the second drive element 91; a second stirring element 93, which is connected to the outer circumference of the second rotary shaft 92.

[0053] The arrangement described above allows the second stirring element 93 to stir the material and convey it to the second discharge pipe 24. This prevents clumping or bridging of the material, ensures its flowability, and makes the material discharge more uniform, thus improving the consistency, continuity, and stability of the material discharge.

[0054] Preferably in the embodiments of the present invention, the first rotary shaft 82 is mounted in the assembly space 28 via a bearing arrangement and the second rotary shaft 92 is also mounted in the assembly space 28 via a bearing arrangement.

[0055] By controlling the rotational position of the material transfer disc 41 and the movement of the first rotating shaft 82 and the second rotating shaft 92, it is possible to flexibly select whether the material is discharged via the first discharge tube 23 or the second discharge tube 24. This allows the goal of quickly and precisely discharging the material to be achieved, thereby increasing the discharge accuracy.

[0056] It should be noted that, as in Fig. As shown in Figure 2, the frame 10 in the embodiments of the present invention comprises a motor mounting plate 4, which is connected to the right side of the transition shell 26. A first drive element 81 is fixedly mounted to the motor mounting plate 4 and connected to the top of the first rotating shaft 82 via a synchronous pulley and a synchronous belt. By controlling the number of steps of the movement of the first drive element 81 in combination with the spiral conveying section on the first rotating shaft 82, the material discharge quantity can be controlled relatively precisely. A rotary table motor plate 6 is connected to the left side of the transition shell 26. A second drive element 91 is mounted on the rotary table motor plate 6 and connected to the top of the second rotating shaft 82 via another pair of synchronous pulleys and synchronous belts.By controlling the number of steps of the movement of the second drive element 91, the dosage entering the second feed channel 32 at the lower part of the second discharge tube 24 can also be precisely controlled. The first drive element 81 and the second drive element 91 are preferably stepper motors.

[0057] As in Fig. 2 and Fig.As shown in Figure 3, the discharge container 21 in the embodiments of the present invention comprises a storage tray 25, a transition tray 26, and a discharge tray 27, which are arranged one after the other. The transition tray 26 is equipped with a mounting chamber 28 and a material passage chamber 29, which is located on at least one side of the mounting chamber 28. The material passage chamber 29 and the mounting chamber 28 are independent of each other. The material passage chamber 29 serves to connect the storage tray 25 to the discharge tray 27. A feed opening 22 is provided on the storage tray 25, and a first discharge pipe 23 and a second discharge pipe 24 are provided on the discharge tray 27.

[0058] The above arrangement ensures a smooth material feed through the feed opening 22 on the storage tray 25. The mounting space 28 of the transition tray 26 provides room for the installation and operation of the internal components. The material passage space 29 serves as a material transport channel and is independent of the mounting space 28, thus preventing the material flow from affecting the operation of the internal components and ensuring smooth material transport. The first discharge pipe 23 and the second discharge pipe 24 on the discharge tray 27 each correspond to different discharge paths. The first discharge pipe 23 is used for the fine discharge of small quantities of material, and the second discharge pipe 24 is used for rapid material discharge. This allows the appropriate discharge mode to be selected as needed, improving the adaptability and efficiency of the device.

[0059] In the exemplary embodiments of the present invention, the interior space at the bottom of the storage tray 25 is designed in the form of an inverted frustum cone. This arrangement utilizes the frustum cone-shaped side wall to absorb the material pressure on the upper part of the storage tray 25 and thus reduce the material pressure on the lower components at the bottom of the storage tray 25.

[0060] In the exemplary embodiments of the present invention, the transition shell 26 is particularly cylindrical and provided on both sides with a material passage space 29. A discharge element 251 is provided in the storage tray 25 above the mounting space 28 of the transition shell 26. The discharge element 251 has a triangular cross-section, i.e., it is shaped like a triangular prism. The discharge element 251 can guide the material in the lower part of the storage tray 25, allowing the material to enter the two material passage cavities 29 and preventing the formation of dead material there. Preferably, the discharge element 251 and the storage tray 25 are manufactured as a single piece.

[0061] In the exemplary embodiments of the present invention, the discharge container 21 in particular additionally comprises a pump-container divider plate 252. A pump-container divider plate 252 is connected to a side of the transition tray 26 facing away from the storage tray 25. The pump-container divider plate 252 is located below the mounting space 28 and is provided with a slope. The material in the material passage space 29 falls onto the slope and slides along this slope into the discharge tray 27. The slope can receive and guide the powdered material falling from the material passage space 29. In one exemplary embodiment, grooves or holes can be provided at the edge of the pump-container divider plate 252 to enable a balance between flow direction and flow control.

[0062] In the exemplary embodiments of the present invention, the interior of the discharge tray 27 has, in particular, the form of two projecting cavities whose side walls are connected to each other. The two projecting cavities are arranged corresponding to the first discharge pipe 23 and the second discharge pipe 24, respectively.

[0063] The operating procedure of the device is as follows: When material needs to be discharged, the drive unit 71 is first activated via an external control unit. As soon as the signal acquisition unit 74 detects one of the several signal outputs 75, the drive unit 71 is stopped. At this point, the first feed channel 31 and the second feed channel 32 on the upper base 8 are each connected to the two discharge channels 42 on the material transfer disk 41. One of the two discharge channels 42 above is also connected to the discharge channel 33 on the lower base 9.

[0064] The second rotary shaft 92 is then activated. This shaft drives the second agitator 93. The material in the discharge tray 27 passes through the second discharge tube 24 into the discharge channel 42 below. The material discharge rate is fixed. After a specific discharge time, the control unit activates the drive unit 71. The drive unit 71 rotates the material transfer disc 41 until the discharge channel 42 is positioned below the first discharge tube 23, below the second discharge tube 24. At this point, the drive unit 71 stops. The powdered material in the discharge channel 42 is discharged directly from the discharge channel 33. The other empty discharge channel 42 is also rotated below the second discharge tube 24. The material from the second discharge tube 24 continues to flow into this discharge channel 42.The above process is repeated until the weight of the discharged material essentially matches the desired weight (this difference range is set in the control unit). The second rotating shaft 92 and the drive unit 71 then stop operating. The described material discharge process not only ensures rapid material discharge but also allows for effective control of the material discharge accuracy.

[0065] The control unit then controls the first drive element 81. The first drive element 81, in turn, drives the first rotary shaft 82 to rotate, enabling the fine discharge of small quantities of material. The discharge path of the powdered material runs via storage tray 25 - transition tray 26 - discharge tray 27 - first discharge pipe 23 - first feed channel 31 - discharge channel 42 (corresponding to the first feed channel 31) - discharge channel 33. As soon as the material in the container below the discharge channel 33 reaches the required quantity, the control unit activates the first drive element 81 to stop operation. This also stops the discharge at the discharge channel 33, thus completing the entire weighing and discharge process.

[0066] The above description shows that the aforementioned embodiments of the present invention achieve the following technical effects: Large quantities of materials can be discharged quickly from the second discharge pipe, and small quantities of materials can be discharged finely from the first discharge pipe, because the discharge area of ​​the first discharge pipe is smaller than that of the second discharge pipe. When material discharge is required, the necessary quantity can be provided quickly because the second discharge pipe has a relatively large discharge area. In the initial phase, it is possible to move the material transfer disc to a position where the second feed channel is connected to one of the multiple discharge channels, allowing the material to enter this discharge channel.The material transfer disc is then moved so that the material-filled discharge channel moves into a position where it connects to the discharge channel. In this way, the material can be transferred multiple times using the material transfer disc, enabling efficient and rapid material discharge. Furthermore, the volume of the discharge channel is fixed; that is, each discharge channel transports a specific quantity of material each time, allowing for precise control of the total amount of material discharged. Shortly before the material discharge is complete, the material transfer disc is in a position where the first feed channel and the discharge channel are connected by one of the multiple discharge channels. The first discharge pipe can then be connected to the discharge channel via the first feed channel and the discharge channel.The first discharge tube has a smaller discharge area, allowing for effective control of the material flow rate and enabling micro-fine material discharge. By controlling the movement position of the material transfer disc, it is possible to flexibly select whether the material is discharged through the first or second discharge tube. This results in fast and precise discharge, improving the accuracy of the material discharge.

To a person skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc., made in the sense and principle of the present invention should be included within the scope of protection of the present invention.
