Technical Field
[0001] This application relates to the field of weighing equipment technology, and in particular to a feeding assembly and weighing equipment. Background Technology
[0002] Currently, the automatic weighing equipment used in industry is mainly applicable to powdered materials or materials with good flowability. It is not suitable for weighing Chinese medicinal materials in the form of blocks, strips, flakes, or other irregular shapes. However, the Chinese medicinal materials in Chinese decoctions (i.e., fixed prescriptions) are often produced in blocks, strips, flakes, or other irregular shapes of varying sizes. Irregular shapes of medicinal materials (such as root and rhizome herbs) have poor flowability and are prone to bridging and clogging in the hopper, resulting in uneven feeding. Utility Model Content
[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a feeding component and weighing device, which aims to solve the technical problems of bridging, clogging and uneven feeding that are prone to occur during the weighing process of irregularly shaped Chinese herbal medicine pieces, and to achieve high-precision and high-efficiency feeding and weighing of Chinese herbal medicine pieces with poor flowability such as block, strip and sheet shapes.
[0004] This application provides the following technical solution: In a first aspect, embodiments of this application provide a feeding assembly, the feeding assembly comprising: The material tray has a feeding port; The material feeding component includes a rotating part and at least one pawl part. The rotating part is rotatably disposed within the material tray, and the at least one pawl part is disposed within the rotating part. The pawl part is located within the material tray. When the rotating part rotates, it can drive the pawl part to rotate, thereby moving the material towards the feed port.
[0005] In some embodiments of the first aspect, the rotating portion extends through the discharge port.
[0006] In some embodiments of the first aspect, the paddle portion is a helical blade, and the feed port is at least partially located below the paddle portion.
[0007] In some embodiments of the first aspect, the number of the paddle portions is multiple, and the multiple paddle portions are evenly distributed along the circumference of the rotating portion.
[0008] In some embodiments of the first aspect, the discharge port is located at the bottom of the tray, and the bottom of the tray is configured as a conical surface that gradually rises from the discharge port to the outer periphery.
[0009] In some embodiments of the first aspect, the feeding assembly further includes: A material guide has at least one material channel that extends along a spiral and has a top end and a bottom end, the top end being connected to the discharge port.
[0010] In some embodiments of the first aspect, the number of feed channels is multiple; And / or, the material guide further has at least one flow control baffle, which is disposed in the material channel or at the outlet of the material channel for adjusting the material flow rate.
[0011] In some embodiments of the first aspect, the feeding assembly further includes a diverter plate located below the feed tray and connected to the discharge port; wherein the upper ends of all the feed channels are connected to the diverter plate.
[0012] In some embodiments of the first aspect, the feeding component further includes a driving part connected to the rotating part, the driving part being used to drive the rotating part to rotate, and the driving part being disposed at the bottom of the diverting plate, and the feeding plate being connected to the diverting plate.
[0013] Secondly, embodiments of this application also provide a weighing device, the weighing device including a feeding component as described in any of the above embodiments.
[0014] The embodiments of this application have the following advantages: This application provides a feeding assembly that operates based on an active mechanical agitation mechanism to overcome bridging and clogging problems caused by irregular material shapes and poor flowability. Irregularly shaped Chinese medicinal herbs, such as lumps, strips, and flakes, to be weighed are placed in a feeding tray. Due to their poor flowability, the materials tend to accumulate haphazardly within the tray, making it difficult for them to flow smoothly and evenly towards the discharge port under natural conditions. A drive mechanism (not shown, such as a motor) activates, rotating the rotating part of the agitator. One or more agitators fixed to the rotating part then move in a circular or near-circular motion within the tray. The rotating agitators directly act on the accumulated material, effectively breaking up the "arched" structure (i.e., bridging) formed by the material within the hopper, preventing blockages caused by mutual jamming. During rotation, the agitators continuously push and deflect material away from the discharge port towards it, providing continuous and directional flow momentum and overcoming the material's inherent lack of flowability. By controlling the rotation speed of the rotating part, the intensity and frequency of the agitation can be adjusted, thereby enabling the material to be discharged from the discharge port in a relatively stable and uniform flow rate, creating the necessary conditions for subsequent high-precision weighing.
[0015] Therefore, compared with the prior art, the feeding assembly and weighing equipment provided in this application have the following significant advantages: By actively intervening with mechanical paddles, the blockage and clogging phenomena that easily occur with irregular materials are fundamentally eliminated, ensuring the continuity and stability of the feeding process and avoiding production interruptions. Active paddle movement makes the material flow direction controllable and the feeding more uniform, effectively reducing errors caused by feeding pulses or interruptions during the weighing process. This significantly improves the weighing accuracy for irregular Chinese herbal medicine pieces, ensuring the accuracy of prescription dosages.
[0016] Clearly, this application specifically targets poorly flowing block, strip, and flake-shaped Chinese medicinal herbs, greatly expanding the applicability of automatic weighing equipment and filling the gap in existing technology for the automatic weighing of complex-shaped Chinese medicinal herbs. It achieves automated and continuous feeding and weighing of difficult-to-handle materials, reducing manual intervention, lowering labor intensity, and improving overall production efficiency. Furthermore, the feeding assembly has a simple structural design, mainly consisting of a material tray and a feeding mechanism, making it easy to manufacture, install, and maintain, and ensuring reliable operation.

[0026] Currently, in related technologies, the automatic weighing equipment used in industry is mainly applicable to powdered materials or materials with good flowability. It is not suitable for weighing Chinese medicinal materials in the form of blocks, strips, flakes, or other irregular shapes. However, the Chinese medicinal materials in Chinese decoctions (i.e., fixed prescriptions) are often produced in blocks, strips, flakes, or other irregular shapes of varying sizes. Irregular shapes of medicinal materials (such as root and rhizome herbs) have poor flowability and are prone to bridging and clogging in the hopper, resulting in uneven feeding.
[0027] As shown in Figure 1 and Figure 2 As shown, in order to solve the above-mentioned technical problems, this application provides a feeding assembly, which includes a material tray 100 and a feeding device 200. The material tray 100 has a discharge port 110. The feeding device 200 includes a rotating part 220 and at least one feeding plate part 210. The rotating part 220 is rotatably disposed in the material tray 100, and at least one feeding plate part 210 is disposed in the rotating part 220. The feeding plate part 210 is located in the material tray 100. When the rotating part 220 rotates, it can drive the feeding plate part 210 to rotate, so as to move the material to the discharge port 110.
[0028] In these embodiments, this application provides a feeding assembly for a weighing device for traditional Chinese medicine decoction pieces. This feeding assembly is particularly suitable for the stable and uniform feeding of traditional Chinese medicine decoction pieces that are in block, strip, flake, or other irregular shapes and have poor flowability, effectively solving the problem of uneven feeding caused by material bridging and blockage in the prior art.
[0029] The material tray 100 is an open-top container structure used to hold the Chinese herbal medicine slices to be weighed. For example, the material tray 100 can be made entirely of stainless steel, which has good wear resistance and hygiene properties, meeting the cleanliness requirements of Chinese herbal medicine processing equipment. The bottom of the material tray 100 has a discharge port 110, which is a circular through-hole. The diameter of the discharge port 110 can be designed according to the average size of the slices, for example, between 20mm and 50mm, to ensure that single or multiple slices can pass through smoothly while preventing excessive material from overflowing instantly. In this embodiment, the discharge port 110 is located in the central area of the bottom of the material tray 100, which facilitates concentrated material discharge.
[0030] Furthermore, the inner wall of the material tray 100 can be designed as a tapered structure that gradually tapers towards the bottom, i.e., wider at the top and narrower at the bottom. This tapered structure helps guide the material to slide towards the central discharge port 110, reducing material accumulation at the edge of the material tray 100 and thus lowering the probability of bridging.
[0031] The material feeding component 200 is disposed inside the material tray 100 and is used to agitate and push the material to ensure that the material flows continuously and evenly and is discharged through the discharge port 110. The material feeding component 200 includes a rotating part 220 and at least one shoveling part 210.
[0032] The rotating part 220 is a shaft-shaped structure rotatably disposed within the material tray 100. In this embodiment, the rotating part 220 is a rotating shaft, both ends of which are rotatably mounted on the material tray 100 via bearings. One end of the rotating shaft extends out of the material tray 100 and is connected to a drive device (not shown). This drive device can be a stepper motor or a servo motor, capable of precisely controlling the rotational speed and start / stop of the rotating shaft.
[0033] The paddle portion 210 is fixedly mounted on the rotating part 220 and located inside the material tray 100. For example, in this embodiment, two paddle portions 210 are provided, symmetrically fixed to the outer periphery of the rotating shaft at 180 degrees. Each paddle portion 210 is a plate-like structure with a certain width and length, and its material can be the same as the material tray 100, namely stainless steel. The length direction of the paddle portion 210 extends radially along the rotating shaft, and its free end (the end away from the rotating shaft) has an appropriate gap from the inner wall of the material tray 100, for example, 2mm to 5mm, to avoid friction with the material tray 100 during operation, while ensuring effective material movement.
[0034] When the drive unit rotates the rotating part 220, the agitator part 210 moves in a circular motion within the material tray 100. During this motion, the agitator part 210 pushes the Chinese herbal medicine slices within the material tray 100, overcoming the friction and adhesion between the materials and continuously moving them towards the central discharge port 110. Due to the continuous stirring action of the agitator, the potential arch structure (i.e., "bridging") of the materials is effectively broken, preventing blockage and ensuring that the materials can be stably and continuously discharged from the discharge port 110.
[0035] In another implementation, the number of dispensing blades can be adjusted according to the characteristics of the material. For example, for medicinal slices with extremely poor flowability and a tendency to clump, three or four dispensing blade sections 210 can be provided to enhance the dispensing effect.
[0036] Therefore, this application solves the problems of bridging, clogging, and uneven feeding that easily occur during the feeding process of irregular Chinese herbal medicine pieces by setting a rotatable feeding component 200 in the feeding tray 100 and using the rotational motion of the feeding component to force the material to move towards the central feeding port 110. This feeding component has a simple structure and reliable operation. When combined with subsequent weighing sensors and control systems, it can achieve high-precision and high-efficiency automatic weighing of Chinese herbal medicine pieces.
[0037] In some embodiments, the rotating part 220 is partially inserted through the feed port 110.
[0038] In these embodiments, the rotating part 220 is a rotating shaft, which is vertically arranged and extends downward at one end, partially passing through the feed port 110.
[0039] Specifically, the discharge port 110 serves not only as a channel for material discharge, but also as a conduit. The end of the rotating shaft (the portion passing through the discharge port 110) extends through it. Located within the discharge port 110, the end of the rotating shaft acts as a guide and anti-bridging agent. When material converges from the surrounding area towards the center, the end of the rotating shaft at the center of the discharge port 110 can break up any material arches that may form at the outlet, further preventing blockages and ensuring smooth material discharge.
[0040] In one embodiment, the portion of the rotating part 220 that passes through the discharge port 110 can be designed as a smooth cylindrical section without a paddle, so as to avoid material jamming in the narrow discharge port 110 area.
[0041] In another embodiment, a small conical or spiral guide (not shown) may be provided at the end of the rotating part 220 passing through the discharge port 110 to further promote the discharge of material from the discharge port 110.
[0042] In some embodiments, the paddle portion 210 is a helical blade, and the feed port 110 is at least partially located below the paddle portion 210.
[0043] In these embodiments, the structure of the paddle portion 210 can be further optimized to improve the continuity and uniformity of material conveying.
[0044] Specifically, the pusher section 210 is configured as a helical blade. This helical blade extends spirally around the axis of the rotating section 220. The pitch of the helical blade (the axial distance between two adjacent helical turns) can be designed according to the material characteristics, for example, selected within the range of 20mm to 80mm. A smaller pitch provides stronger pushing force, suitable for heavier or easily agglomerated medicinal slices; a larger pitch facilitates rapid material flow, suitable for lighter or slightly more fluid medicinal slices. The rotation direction of the helical blade (left-hand or right-hand) can be determined according to the rotation direction of the drive device and the material conveying requirements.
[0045] Furthermore, the structure of the feed tray 100 is adapted to the position of the feeding member 200, such that the feed port 110 is at least partially located below the spiral blade. Preferably, the central region of the feed port 110 is completely within the projection range of the spiral blade. In this embodiment, the feed port 110 is located at the center of the bottom of the feed tray 100, while the spiral blade extends axially from one end of the rotating part 220 and covers the area above the feed port 110.
[0046] When the drive unit rotates the rotating part 220, the spiral blades rotate accordingly. Due to the characteristics of the spiral structure, during rotation, it not only applies radial thrust to the material, but more importantly, it generates an axial force along the spiral direction. This axial force guides the material to move continuously and stably along the spiral path towards the center (i.e., towards the discharge port 110). Driven by the spiral blades, the material is conveyed to the discharge port 110 below its end and discharged from there.
[0047] The spiral blade structure enables forced material conveying, which is far more effective than simple stirring or agitation. Under the action of the spiral force, the material is continuously pushed towards the center, fundamentally solving the bridging and blockage problems caused by the poor flow of irregularly shaped medicinal slices due to gravity, and achieving truly continuous and uniform feeding.
[0048] Because the material flow is more stable and predictable, the amount of material discharged each time fluctuates less, thus significantly improving the accuracy of subsequent weighing processes. By adjusting the pitch, direction of rotation, and speed of the spiral blades, it can flexibly adapt to Chinese herbal medicine slices of different shapes, densities, and flowability, demonstrating good versatility.
[0049] In one alternative embodiment, the spiral blades can extend from one end of the rotating part 220 to the other end to form a complete spiral conveying channel, maximizing conveying efficiency.
[0050] In some embodiments, there are multiple paddle portions 210, which are evenly distributed along the circumference of the rotating portion 220.
[0051] In these embodiments, the paddle portion 210 may employ multiple independent plate-like or strip-like structures, rather than continuous helical blades.
[0052] Specifically, there are multiple paddle sections 210, and these multiple paddle sections 210 are evenly distributed along the circumference of the rotating part 220. In this embodiment, there are three paddle sections 210, which are arranged in a star-shaped symmetrical arrangement around the axis of rotation at an included angle of 120 degrees. Each paddle section 210 is a rigid plate with a certain width and thickness, one end of which is fixedly connected to the outer peripheral surface of the rotating part 220, and the other end is a free end pointing towards the inner wall of the tray 100, but with an appropriate gap.
[0053] Multiple paddles can simultaneously push the material from different directions when rotating, forming a more thorough agitation, effectively breaking up clumps of medicinal slices, and disrupting the arch structure formed by the material in the tray 100.
[0054] Because the paddles are evenly distributed on the circumference, the pushing effect on the material is more balanced with each rotation, avoiding the material deviation phenomenon that may be caused by unilateral or asymmetrical paddle movements, thus ensuring the uniformity and stability of the material flow towards the central discharge port 110.
[0055] Compared to spiral blades, multiple independent paddles are easier to process and install, have lower manufacturing costs, and are easier to adjust the number and angle of paddles according to actual needs.
[0056] Optionally, the number of dispensing sections 210 can be adjusted according to the size of the tray 100 and the characteristics of the material. For example, two dispensing sections 210 can be provided for a small tray 100 or for materials with good flowability. For a large tray 100 or for materials that are prone to bridging, four, five or even more dispensing sections 210 can be provided to enhance the material dispensing capability.
[0057] In addition, the shapes of the multiple prying sections 210 can be diversified, for example, they can be designed as straight plates, L-shaped, arc-shaped or with serrated edges, to adapt to the physical properties of different medicinal slices, reduce damage to the materials or enhance the crushing effect.
[0058] In some embodiments, the discharge port 110 is located at the bottom of the tray 100, and the bottom of the tray 100 is configured as a conical surface that gradually rises from the discharge port 110 to the outer periphery.
[0059] In these embodiments, the bottom structure of the tray 100 is specifically designed to optimize material flow. Specifically, the discharge port 110 is located in the central region of the bottom of the tray 100. More importantly, the bottom of the tray 100 is constructed as a conical surface that gradually rises outward from the discharge port 110. This conical surface starts from the edge of the discharge port 110 and rises smoothly towards the sidewall of the tray 100, with its inclination angle (i.e., the angle between the conical surface and the horizontal plane) preferably between 15° and 45°.
[0060] Because the bottom is conical with a low center and high edges, the material will naturally slide towards the lowest point in the center, i.e., the discharge port 110, under the influence of gravity. This self-flowing design greatly reduces the accumulation of material on the edges or corners of the tray 100, providing favorable initial conditions for the pushing action of the feeding component 200.
[0061] The inclined structure of the conical surface can disrupt the horizontal arch bridge that the material may form. When the material begins to form a bridging tendency due to friction or adhesion, its support point is located on the inclined surface, which has poor stability and is more likely to collapse under gravity and slight disturbance. This creates a synergistic effect with the mechanical arch-breaking action of the material feeder 200, providing double protection for smooth material feeding.
[0062] When the feeding process ends or the material is changed, the conical bottom helps the residual material to slide automatically towards the center and be discharged under the action of gravity, reducing dead corners, facilitating cleaning, and meeting the hygiene requirements of traditional Chinese medicine equipment.
[0063] In this embodiment, the conical surface can smoothly transition with the sidewall of the material tray 100 to form a continuous inner surface, avoiding structures that easily accumulate material, such as steps or depressions. The surface of the conical surface should be smoothed to reduce material flow resistance.
[0064] In some embodiments, the feeding assembly further includes a guide 300 having at least one channel 310 extending along a spiral and having a top end and a bottom end, the top end being connected to the discharge port 110.
[0065] In these embodiments, in order to further optimize the flow path of materials from the material tray 100 to the subsequent weighing or conveying stage, the feeding assembly also includes a guide component 300.
[0066] Specifically, the guide component 300 is disposed below the material tray 100 and is fixedly connected to or integrally formed with the material tray 100. The guide component 300 has at least one material channel 310 inside. The material channel 310 extends along a spiral line and has a top end and a bottom end. The top end of the material channel 310 is connected to the discharge port 110 of the material tray 100, allowing material discharged from the discharge port 110 to directly enter the top end of the material channel 310.
[0067] In this embodiment, the spiral of the material channel 310 can be an Archimedean spiral or an equidistant spiral, and its spiral radius and pitch can be designed according to the equipment space layout and material falling speed requirements. The bottom end of the material channel 310 opens towards the weighing hopper or the inlet of the next process.
[0068] Traditional Chinese medicine decoction pieces are usually brittle materials, and free fall directly from the feed inlet 110 may cause breakage. The spiral-extended feed channel 310 causes the material to slide along the spiral path, prolonging the falling path and time, effectively reducing the falling speed and impact force of the material, and reducing mechanical damage and powdering of the decoction pieces during the conveying process.
[0069] The spiral structure plays a certain role in throttling and guiding the flow of materials, preventing splashing or clogging of downstream equipment due to a sudden surge of large amounts of material, and ensuring that the material is discharged smoothly and orderly.
[0070] The spiral feed channel 310 can achieve a long conveying distance within a limited vertical space, facilitating a compact overall design for the equipment. Furthermore, its bottom outlet direction can be flexibly adjusted (e.g., horizontal or inclined output) to adapt to the interface positions of different downstream devices.
[0071] The top of the guide component 300 is tightly connected to the discharge port 110, eliminating the gap between the two and preventing the material from getting stuck at the connection or forming a new bridging point.
[0072] In one alternative embodiment, the inner wall of the feed channel 310 may be configured as a smooth curved surface and polished to further reduce material flow resistance.
[0073] In some embodiments, there are multiple material channels 310. And / or, the guide member 300 also has at least one flow control baffle 400, which is disposed in the material channel 310 or at the outlet of the material channel 310 for regulating the material flow rate.
[0074] In these embodiments, the structure of the feed guide 300 can be designed in various ways to meet the flow control and parallel processing requirements under different operating conditions.
[0075] The number of feed channels 310 can be multiple. In this embodiment, the guide member 300 has two independent spiral feed channels 310 inside, which are arranged side by side or in a concentric spiral structure. The design of multiple feed channels 310 has the following advantages: It can simultaneously transport materials to multiple weighing hoppers or downstream workstations, improving overall production efficiency and is suitable for multi-station automatic dispensing systems.
[0076] When the amount of material fed at one time is large, multiple material channels 310 can divert the material to avoid blockage of a single channel due to excessive material, thus ensuring smooth conveying.
[0077] When one material channel 310 is unexpectedly blocked, the other material channels 310 can still continue to operate, improving the reliability and fault tolerance of the equipment.
[0078] To achieve precise control of material flow rate, the guide component 300 also has at least one flow control baffle 400. The flow control baffle 400 can be disposed inside the material channel 310 or at the outlet of the material channel 310 (i.e., near the bottom).
[0079] Specifically, the flow control baffle 400 is an adjustable metal or engineering plastic sheet, one end of which is fixed to the inner wall of the material channel 310 by a hinge or sliding mechanism. By using an external adjustment knob or electric actuator, the insertion angle or depth of the flow control baffle 400 in the material channel 310 can be changed, thereby adjusting the effective flow cross-sectional area of the material channel 310 and realizing stepless or graded adjustment of the material flow rate.
[0080] For example, the front end of the flow control baffle 400 is connected to one side wall of the feed channel 310, the rear end of the flow control baffle 400 is located downstream of the front end, and the flow control baffle 400 is inclined.
[0081] In some embodiments, the feeding assembly further includes a diversion plate 500, which is located below the material tray 100 and is connected to the discharge port 110; wherein, the upper ends of all the material channels 310 are connected to the diversion plate 500.
[0082] In these embodiments, the feeding assembly also includes a diverter plate 500 in order to achieve uniform distribution and efficient parallel conveying of materials.
[0083] Specifically, the diversion plate 500 is located below the material tray 100 and above the guide member 300. The diversion plate 500 has one inlet and multiple outlets. The inlet is connected to the discharge port 110 of the material tray 100, so that the material discharged from the discharge port 110 first enters the internal cavity of the diversion plate 500.
[0084] More importantly, when the guide component 300 has multiple material channels 310, the upper ends of all material channels 310 are connected to the corresponding discharge ports of the distribution plate 500. In this way, the material flowing out of the discharge port 110 of the material tray 100 first gathers into the distribution plate 500, and then is evenly distributed by the distribution plate 500 to each independent spiral material channel 310.
[0085] As an intermediate buffer and distribution chamber, the diversion plate 500 can smoothly and evenly distribute the material flow from a single source (feed port 110) to multiple downstream material channels 310, avoiding uneven flow or flow deviation caused by each material channel 310 being directly connected to the feed port 110, and ensuring that the material quantity in each conveying channel is consistent.
[0086] The cavity space of the diverter plate 500 acts as a buffer for the material flow, smoothing out the flow pulsation caused by the intermittent prying of the feeder 200, making the material flow into each feed channel 310 more stable and continuous, which is conducive to improving the accuracy of subsequent weighing.
[0087] The diversion plate 500, as an independent component, is easy to match with different numbers and layouts of guide components 300. By replacing the diversion plate 500 and the corresponding multi-channel guide components 310, the parallel processing capacity of the equipment can be quickly adjusted to meet the needs of different production scales.
[0088] In one alternative embodiment, the bottom of the inner cavity of the diversion plate 500 can be designed as an inclined or conical surface that slopes towards multiple discharge ports, using gravity to assist the material to flow to each outlet and prevent material accumulation in the central area.
[0089] In another alternative implementation, a static guide cone (not shown) can be disposed inside the diversion plate 500, located directly below the feed inlet. When material falls in, the guide cone reflects it in all directions, guiding it more evenly to each discharge outlet, further optimizing the diversion effect.
[0090] In some embodiments, the feeding component 200 further includes a driving part, which is connected to the rotating part 220. The driving part is used to drive the rotating part 220 to rotate, and the driving part is disposed at the bottom of the diverting plate 500. The material tray 100 is connected to the diverting plate 500.
[0091] In these embodiments, the drive unit is connected to the rotating unit 220 and is used to drive the rotating unit 220 to rotate about its axis. In this embodiment, the drive unit is a miniature geared motor, whose output shaft is fixedly connected to the extension end of the rotating unit 220 via a coupling or directly.
[0092] Crucially, the drive unit is located at the bottom of the distributor plate 500. The bottom of the distributor plate 500 has a mounting cavity or mounting base (not shown) for mounting and accommodating the drive unit. The output shaft of the drive unit passes upward through the bottom wall of the distributor plate 500 and connects to the rotating part 220 located above the distributor plate 500.
[0093] Meanwhile, the material tray 100 and the diverter plate 500 are fixedly connected by bolts, clips, or welding to form a single, stacked module. This connection method allows the material tray 100, the diverter plate 500, and the drive unit to be tightly integrated in space.
[0094] The drive unit is cleverly placed at the bottom of the diversion plate 500, making full use of the unused space under the equipment and avoiding the need to set up additional motor brackets on the side wall or top of the material tray 100. This makes the overall structure more compact and beautiful, which is conducive to the miniaturization design of the equipment.
[0095] The drive unit is located at the bottom, away from the area where materials directly fall into the tray 100, reducing the risk of material dust entering the motor. This location also facilitates the installation of protective covers or sealing structures, improving the reliability and service life of the drive system.
[0096] Furthermore, when the drive unit is a motor, the vibration generated during motor operation is beneficial for material feeding.
[0097] In some embodiments, this application also provides a weighing device, which includes any of the feeding components described in the above embodiments.
[0098] Since the above-mentioned feeding component has the above-mentioned technical effects, the weighing equipment including the feeding component should have the same technical effects, which will not be elaborated here.
[0099] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
