[0002] With the continuous improvement of industrial production automation, material dispensing and metering equipment has been widely used in various industries. Material dispensing and metering equipment is mainly used for the precise measurement and distribution of materials, playing a vital role in the food, pharmaceutical, and chemical industries. Currently, common material dispensing and metering equipment on the market mainly includes vibrating feeders, weighing and dispensing devices, and electronic weighing scales.

[0003] In the prior art, CN113928636A discloses a high-precision multi-station pharmaceutical weighing and dispensing device. This device includes a fixed frame, a hopper, a multi-stage feeding assembly, and a vibration assembly. By setting the multi-stage feeding assembly, the material is vibrated and dispensed. The dispensing end of the feeding assembly is set to a low-frequency vibration for high-precision dispensing to ensure dispensing accuracy. CN216636876U discloses a three-head electronic weighing scale for tea packaging, including a frame, a hopper, a small vibrating feeder, a large vibrating feeder, a weighing hopper, and an opening linkage mechanism. The small vibrating feeder, the large vibrating feeder, and the weighing hopper are combined into three groups, and each group of weighing hoppers dispenses material into the dispensing hopper in turn after weighing.

[0004] In addition, CN109049343B discloses a batching system for a concrete mixing plant. This system includes a frame, a feeding hopper, a weighing hopper, and a distributing component. By setting the distributing component within the weighing hopper, it divides the hopper into four weighing zones, enabling the differentiation of materials to be weighed. CN109866967A discloses an automatic weighing and packaging machine for traditional Chinese medicine decoction pieces, including a frame, a feeding hopper, a main vibrating plate, a linear vibrating plate, a storage hopper, a weighing hopper, and a combined receiving trough. It can simultaneously perform automatic and accurate weighing and distributing of traditional Chinese medicine decoction pieces of the same or different weights. CN217477584U discloses a rapid four-head scale, including a hopper, a storage bin, a coarse feed channel, a fine feed channel, a weighing component, and a collection hopper. It employs a combination of coarse and fine feed methods to improve weighing accuracy.

[0005] However, existing material dispensing and metering equipment still has some technical problems. First, most equipment struggles to maintain stable dispensing performance during continuous operation, especially when handling materials of different shapes and densities, easily leading to clogging or uneven dispensing. Second, existing equipment is insufficient in counting accuracy, particularly for high-speed moving materials, making precise counting difficult and affecting the quality and consistency of the final product. Furthermore, the structural design of existing equipment is often complex, increasing manufacturing and maintenance costs and reducing production efficiency. Finally, most equipment lacks a flexible dispensing control mechanism, unable to quickly adjust dispensing parameters according to different production needs, limiting the equipment's application range.

[0006] Therefore, there is an urgent need for a material dispensing and metering device that is simple in structure, uniform in material distribution, accurate in counting, and highly adaptable, in order to meet the needs of modern industrial production for precise material measurement and efficient distribution.

[0026] In this embodiment, the frame 100 includes a support 110 and a mounting base 120. The mounting base 120 is connected to the inner wall of the support 110 through several connecting plates 130 evenly arranged on its outer periphery.

[0027] In some embodiments, the mounting base 120 includes a base plate 121, which is mounted on a support structure 122 surrounded by a plurality of plates. The outer periphery of the support structure 122 is evenly provided with a plurality of connecting plates 130 that connect to the inner wall of the bracket 110. This design allows the mounting base 120 to be securely installed inside the bracket 110, improving the structural stability of the entire device. In some embodiments, a mounting base 120 is provided, the structure of which is disclosed in the accompanying drawings.

[0030] In some embodiments, the feeding assembly 210 includes a supporting circular tube 211 mounted on a base plate 121. A conical material guide member 212 is provided at the top of the supporting circular tube 211. A hopper shell 213 with a plurality of material guide ports is connected to the outer periphery of the conical material guide member 212.

[0031] In some embodiments, the hopper discharge assembly 220 includes an angled discharge base plate 221 and a hopper discharge component 222. The angled discharge base plate 221 is mounted on the vibration assembly 230. The hopper discharge component 222 is located below the hopper shell 213 in the feeding assembly 210 and cooperates with the conical guide component 212 to discharge material. The discharge port of the hopper discharge component 222 falls into the angled discharge base plate 221. A feeding chute 223 for guiding material to the weighing and distributing unit 400 is provided below the discharge end of the angled discharge base plate 221.

The top of the body 231 is connected to a mounting base plate 234, and the angled discharge base plate 221 is connected to the mounting base plate 234. The bottom of the body 231 is connected to the springs 232. In some embodiments, the body 231 is a structure or device that can provide vibration function, so that the vibration assembly 230 can make the material flow out of the angled discharge base plate 221 evenly through vibration, preventing material blockage.

[0033] In some embodiments, the metering unit 300 is disposed at the outlet of the feeding and distributing unit 200 and is used to count the quantity of material falling from the feeding and distributing unit 200. In some embodiments, the metering unit 300 includes a camera component 310, a lighting component 320, and a control component. The camera component 310 and the lighting component 320 are both electrically connected to the control component. The lighting component 320 is mounted on the outer end of the mounting bracket 225 for mounting the feeding chute 223, and the camera component 310 is mounted on the inner side of the bracket 110. By using the camera component 310 and the lighting component 320 in conjunction with the control component, the quantity of material falling from the feeding chute 223 can be accurately counted, achieving precise metering.

[0034] In some embodiments, the weighing and dispensing unit 400 includes a flap assembly 410, a first weighing hopper 420, and a second weighing hopper 430 and a third weighing hopper 440 symmetrically arranged below the first weighing hopper 420. The flap assembly 410 is configured to guide material falling from the first weighing hopper 420 to the second weighing hopper 430 or the third weighing hopper 440. The flap assembly 410 includes a partition plate 411 disposed above the second weighing hopper 430 and the third weighing hopper 440. A partition shaft 412 is disposed at the bottom of the partition plate 411. The partition shaft 412 is movably engaged with the hopper body of the second weighing hopper 430 and the third weighing hopper 440 through a mounting bearing seat. One end of the partition shaft 412 is connected to a partition arm 413, which is movably engaged with a telescopic member 414 movably disposed on the mounting base 120. By controlling the extension and retraction of the telescopic member 414, the partition plate 411 can be rotated, thereby guiding the material to the second weighing hopper 430 or the third weighing hopper 440, thus achieving material diversion. In some embodiments, the first weighing hopper 420, the second weighing hopper 430, and the third weighing hopper 440 all adopt conventional technology in the field, as shown in the figure. They include a double-door structure and a metering component, which can be used to measure the weight of the material in the weighing hopper, facilitating material diversion.

[0035] In some embodiments, the hopper unit 500 is disposed inside the support 110 and is used to collect materials falling from the weighing and distributing unit 400. The hopper unit 500 includes a discharge guide 510 composed of a plurality of inclined sliding plates arranged in a surrounding arrangement. The inner wall of the discharge guide 510 is evenly provided with a plurality of distributing plates 520, and the outlet of the discharge guide 510 is provided with a double-opening door mechanism 530. This design allows materials to flow smoothly from the weighing and distributing unit 400 into the hopper unit 500, and the final discharge of materials is controlled by the double-opening door mechanism 530.

[0036] During operation, material enters the hopper shell 213 through the feed hopper 214, and is then evenly distributed to various guide ports by the conical guide component 212. It then falls into the angled discharge base plate 221 via the hopper discharge component 222. At this time, the vibration component 230 vibrates the angled discharge base plate 221, and the material flows along the angled discharge base plate 221 to the feeding chute 223. The metering unit 300 counts the material falling from the feeding chute 223, and the material falls into the first weighing hopper 420. When the material in the first weighing hopper 420 reaches the preset weight, the material falls from the first weighing hopper 420 and is guided by the flip-plate component 410 to the second weighing hopper 430 or the third weighing hopper 440. Finally, the material falls from the second weighing hopper 430 or the third weighing hopper 440 into the discharge hopper unit 500, where the discharge process is completed by the discharge guide hopper 510 and the double-opening door mechanism 530.

[0037] This material dispensing and metering equipment achieves precise measurement and distribution of materials through the coordinated operation of the feeding and dispensing unit 200, the metering unit 300, the weighing and dispensing unit 400, and the unloading hopper unit 500. This improves the efficiency and accuracy of material dispensing and meets the material dispensing needs under different working conditions.

[0038] The present invention also discloses several possible embodiments, wherein the metering unit 300 includes a camera assembly 310, a lighting assembly 320, and a control assembly. Both the camera assembly 310 and the lighting assembly 320 are electrically connected to the control assembly. The lighting assembly 320 is mounted on the outer end of the mounting bracket 225 for mounting the feeding chute 223. The camera assembly 310 is mounted on the inner side of the bracket 110. The camera assembly 310, in conjunction with the lighting assembly 320 and the control assembly, is used to count the amount of material falling from the feeding chute 223.

[0039] In some embodiments, as shown in the figure, the camera assembly 310 of the metering unit 300 includes a camera and a lens. The camera is a high-resolution industrial camera with high-speed shooting capability, capable of capturing fast-moving materials. The lens has a wide-angle design to ensure coverage of the entire discharge area of ​​the feed chute 223. The camera assembly 310 is fixed to the inner side of an adjustable bracket 110, which can be adjusted in angle and height to obtain the optimal shooting angle. The installation position of the camera assembly 310 is precisely calculated to ensure that every piece of material falling from the feed chute 223 can be clearly captured.

[0040] In some embodiments, the lighting assembly 320 includes an LED light source and a reflector. The LED light source is arranged in a ring to provide uniform illumination and avoid shadow interference. The reflector is made of a special material that can focus light on the area where the material falls, enhancing image contrast. The lighting assembly 320 is mounted on the outer end of the mounting bracket 225, and its position forms an optimal illumination angle with the camera assembly 310 to ensure that the material is clearly captured during its fall. The brightness of the lighting assembly 320 is adjustable to adapt to different ambient light conditions and different material characteristics.

[0041] In some embodiments, the control component (not shown) is disposed on one side of the device of the present invention. The control component includes a processor, a memory, and a communication module. The processor uses a high-performance industrial-grade chip and is capable of processing image data acquired by the camera component 310 in real time. The memory is used to store image processing algorithms and counting data. The communication module supports multiple communication protocols and can exchange data with a host computer or other devices. The control component has a built-in image recognition algorithm that can accurately identify materials of different shapes, sizes, and colors and perform real-time counting. The control component also has a self-learning function, which can continuously optimize the recognition algorithm based on actual usage to improve counting accuracy. During operation, when materials fall from the feeding chute 223, the lighting component 320 provides a stable light source, and the camera component 310 captures the image of the falling material and transmits the image signal to the control component. The control component identifies the materials and counts them using the image processing algorithm. The counting results can be displayed in real time on the display screen or transmitted to the host computer for recording and analysis via the communication module.

[0042] In some embodiments, the camera assembly 310 employs a high-speed camera capable of capturing images at 120 frames per second, suitable for high-speed material counting scenarios. The high-speed camera, combined with a dedicated image processing algorithm, maintains a counting accuracy of over 99.9%, even when materials are falling at high speeds.

[0043] In some embodiments, the lighting assembly 320 employs an adjustable color temperature LED light source, which can adjust the color temperature of the light source according to the color characteristics of different materials, thereby improving the accuracy of image recognition. The adjustable color temperature range is 3000K-6500K, adapting to various material colors and ambient lighting conditions.

[0044] In some embodiments, the control component integrates an artificial intelligence algorithm that can automatically identify and eliminate foreign object interference, counting only the target material. This algorithm, through deep learning technology, can distinguish between normal materials and foreign objects, significantly improving the accuracy and reliability of the counting.

[0045] The metering unit 300, through the coordinated operation of the camera assembly 310, the lighting assembly 320, and the control assembly, achieves accurate counting of materials falling from the feeding chute 223. This metering unit 300 has advantages such as easy installation, accurate counting, and strong adaptability, and can meet the material counting needs in various industrial production processes.

[0046] In some embodiments, the flip plate assembly 410 includes a partition plate 411 disposed above the second weighing hopper 430 and the third weighing hopper 440. A partition shaft 412 is disposed at the bottom of the partition plate 411. The partition shaft 412 is movably engaged with the hopper body of the second weighing hopper 430 and the third weighing hopper 440 through a mounting bearing seat. One end of the partition shaft 412 is connected to a partition lever arm 413, which is movably engaged with a telescopic member 414 movably disposed on the mounting base 120.

[0047] In some embodiments, the structure of the flap assembly 410 is primarily designed to control the distribution of material between the second weighing hopper 430 and the third weighing hopper 440. The partition plate 411 is a flat plate structure made of wear-resistant steel, possessing sufficient strength and rigidity to withstand material impact without deformation. The upper surface of the partition plate 411 is smooth to reduce frictional resistance and facilitate smooth material flow. The width of the partition plate 411 matches the opening width of the second weighing hopper 430 and the third weighing hopper 440, ensuring complete coverage or separation of the two weighing hoppers during operation.

[0048] In some embodiments, the partition shaft 412 is positioned at the centerline of the bottom of the partition plate 411. It is made of high-strength alloy steel and its surface is hardened to improve wear resistance and service life. Both ends of the partition shaft 412 extend to the outer sides of the second weighing hopper 430 and the third weighing hopper 440, respectively, and are connected to mounting bearing seats installed on the outer wall of the hoppers. The mounting bearing seats contain precision bearings to ensure smooth rotation of the partition shaft 412, reducing motion resistance and noise.

[0049] In some embodiments, the bearing mounting housing is made of cast steel and is bolted to the outer wall of the second weighing hopper 430 and the third weighing hopper 440. The bearing mounting housing is designed to meet the dustproof and lubrication requirements of the bearings, and is equipped with internal sealing rings and lubrication oil chambers to extend the service life of the bearings.

[0050] In some embodiments, the separating arm 413 is connected to one end of the separating shaft 412 and is made of high-strength aluminum alloy to reduce weight while ensuring sufficient strength. The length of the separating arm 413 is precisely calculated to ensure that it can provide sufficient torque under the action of the telescopic member 414 to rotate the separating plate 411 to a predetermined position. The end of the separating arm 413 is provided with a connecting hole and is fitted with a connecting shaft post, which is connected to the movable end of the telescopic member 414 via a pin.

[0051] In some embodiments, one end of the telescopic member 414 is movably mounted on the mounting base 120, and the other end is movably engaged with the separating force arm 413. The telescopic member 414 adopts a cylinder structure, including a cylinder body, a piston, and a piston rod. The cylinder body is movably mounted on the mounting base 120, and the end of the piston rod is connected to the separating force arm 413 via a pin. In some embodiments, the cylinder's air inlet and exhaust port are connected to a solenoid valve control system, which can precisely control the cylinder's telescopic speed and position.

[0052] In some embodiments, the mounting base 120 is fixed on the frame 100, and its position is coordinated with the positions of the second weighing hopper 430 and the third weighing hopper 440 to ensure that the telescopic component 414 can work normally. The mounting base 120 adopts a welded steel plate structure, which has sufficient rigidity to withstand the reaction force generated by the telescopic component 414 during operation without deformation.

[0053] The working principle of the flip-plate assembly 410 is as follows: When it is necessary to guide material to the second weighing hopper 430 or the third weighing hopper 440, the control system sends a signal, and the solenoid valve controls the extension and retraction of the cylinder, causing the separating arm 413 to move to one side, thereby driving the separating shaft 412 to rotate. This causes the separating plate 411 to tilt towards the third weighing hopper 440 or the second weighing hopper 430, and the material will slide along the surface of the separating plate 411 into the second weighing hopper 430 or the third weighing hopper 440. By adjusting the extension and retraction speed and stroke of the cylinder, the tilt angle and flipping speed of the separating plate 411 can be precisely controlled to meet different material characteristics and production requirements. The tilt angle of the separating plate 411 can usually be adjusted within the range of 0-45 degrees to adapt to materials with different flowability.

[0054] The design of the flap assembly 410 makes the material distribution process more precise and controllable, reduces material loss and errors during distribution, and improves the working efficiency and accuracy of the weighing system. At the same time, the structure is simple, reliable, easy to maintain, and has a long service life.

[0055] In some embodiments, the base plate 121 serves as the basic support structure of the vibration assembly 230. It is made of metal and possesses sufficient strength and stability to support all components of the vibration assembly 230. The upper surface of the base plate 121 has mounting holes for fixing the base plate 233. Shock-absorbing pads are provided at the four corners of the base plate 121 to effectively reduce the vibration impact of the vibration assembly 230 on the external environment during operation. The base plate 233 is fixedly mounted on the base plate 121. The base plate 233 is made of a metal sheet of moderate thickness with an anti-corrosion treatment. The base plate 233 has multiple connection points for connecting the springs 232. These connection points are evenly distributed on the surface of the base plate 233 to ensure uniform force distribution on the springs 232.

[0056] In some embodiments, the vibration assembly 230 includes several springs 232, typically four or six, as shown in the figure, arranged in four groups, evenly distributed on the substrate 233. The springs 232 are made of a high-elasticity alloy material, possessing excellent elastic recovery and fatigue resistance. The lower end of the spring 232 is fixedly connected to the substrate 233, and the upper end is connected to the bottom of the body 231. The design parameters of the spring 232 include spring stiffness, wire diameter, and number of turns, which are precisely calculated and selected based on the working load and vibration frequency requirements of the vibration assembly 230. During the operation of the vibration assembly 230, the springs 232 buffer and transmit vibrations, ensuring effective utilization of vibration energy while preventing excessive vibration from damaging the equipment.

[0057] In some embodiments, the body 231 is the core component of the vibration assembly 230, made of high-strength alloy material, possessing sufficient rigidity and durability. The bottom of the body 231 has interfaces for connecting to the spring 232; these interfaces are tightly connected to the upper end of the spring 232 to ensure the stability of vibration transmission. A vibration motor or other vibration source is installed inside the body 231; when the vibration source operates, the generated vibration force is transmitted to the entire vibration assembly 230 through the body 231. The top of the body 231 is designed as a flat mounting surface for connecting to the mounting base plate 234.

[0058] In some embodiments, the mounting base plate 234 is connected to the top of the body 231, and is made of wear-resistant material with a smooth and flat surface. The mounting base plate 234 and the body 231 are fastened together by bolts to ensure that there is no relative displacement between them. The upper surface of the mounting base plate 234 is designed with a special connection structure for connecting with the angled discharge base plate 221. The function of the mounting base plate 234 is to provide a stable mounting foundation for the angled discharge base plate 221, and at the same time transmit the vibration of the body 231 to the angled discharge base plate 221.

[0059] In some embodiments, the angled discharge base plate 221 is fitted onto the mounting base plate 234. The angled discharge base plate 221 is made of a wear-resistant and smooth material, and its surface is specially treated to reduce the frictional resistance between the material and the base plate 121. The design angle of the angled discharge base plate 221 is optimized according to the characteristics of the material, generally between 15° and 45°. This angle ensures that the material slides smoothly under vibration without causing the material to slide too quickly due to an excessively large angle. The edge of the angled discharge base plate 221 is provided with a baffle to prevent the material from sliding off the side.

[0060] In some embodiments, by taking into account the control of vibration direction and vibration intensity in the design of the body 231 of the vibration component 230, the vibration parameters can be adjusted according to the characteristics of different materials.

[0061] The working principle of the vibration assembly 230 is as follows: When the vibration source is activated, the generated vibration force is first transmitted to the main body 231, and then, through the elastic action of the spring 232, the main body 231 vibrates regularly. This vibration is transmitted through the main body 231 to the mounting base plate 234, and then to the angled discharge base plate 221. When the material is placed on the angled discharge base plate 221, under the action of vibration, the material overcomes the static friction between itself and the angled discharge base plate 221 and begins to slide along it. Due to the inclined design of the angled discharge base plate 221, the material is discharged evenly in a predetermined direction under the combined action of gravity and vibration. The spring 232 plays a role in buffering and adjusting the vibration intensity throughout the process, ensuring smooth and effective vibration.

[0062] In some embodiments, the body 231 may be equipped with an adjustment mechanism for adjusting the vibration frequency and amplitude to adapt to materials of different types and particle sizes. In some embodiments, the adjustment mechanism includes a frequency adjustment knob and an amplitude adjustment rod, which can be easily adjusted by the operator according to actual needs to improve discharge efficiency and uniformity.

[0063] The vibration assembly 230, through its rationally designed vibration transmission path and angled discharge base plate 221, achieves uniform and continuous material discharge, making it suitable for conveying and distributing various powdery and granular materials. The vibration assembly 230 features a simple structure, convenient maintenance, and reliable operation, meeting the material conveying needs of different industrial production lines.

[0064] During the operation of this device, the material enters the system through the feeding and distributing unit 200. The vibration component 230 in the feeding and distributing unit 200 drives the inclined discharge bottom plate 221 in the hopper discharge component 220 to vibrate, so that the material is evenly dispersed and falls. When the material falls from the feeding chute 223, the camera component 310 in the metering unit 300 captures the material image under the illumination of the lighting component 320. The control component analyzes and counts the image. The material then enters the first weighing hopper 420. Then, according to the position of the partition plate 411 of the flip plate component 410, the material is guided into the second weighing hopper 430 or the third weighing hopper 440. The partition plate 411 is connected to the telescopic component 414 through the partition shaft 412 and the partition lever arm 413, which can adjust the distributing direction. Finally, the material falls from the weighing and distributing unit 400 into the unloading hopper unit 500. Guided by the inclined sliding plate and the distributing plate 520, it is finally discharged from the double-opening door mechanism 530.

[0065] This material dispensing and metering equipment achieves uniform material dispersion through the feeding and dispensing unit 200, accurate counting through the metering unit 300, material diversion and weighing through the weighing and dispensing unit 400, and orderly collection and discharge of materials through the discharge hopper unit 500. The overall structure is compact, the material dispensing is precise, and the metering is accurate, making it suitable for dispensing and metering various granular materials.
