Description

Technical Field

[0001] This invention mainly relates to the technical field of feeding equipment, specifically a feeding device and method suitable for high-viscosity solid non-uniformly agglomerated powder materials. Background Technology

[0002] Automatic feeders, as advanced conveying equipment in the domestic powder material field, are particularly adept at efficiently transferring powders to higher levels and accurately filling them into the hoppers of packaging machines, injection molding machines, and crushers. Their design aims to reduce the physical burden on workers and effectively control dust pollution that may occur during powder addition, thereby creating a cleaner and safer working environment.

[0003] Currently, the mainstream automatic feeding machines on the market are mainly divided into two types: tracked and auger-type. Auger-type automatic feeding machines use a motor-driven screw rotation method for material conveying. The screw drives the material to rotate within a closed pipe, effectively reducing dust leakage, improving the cleanliness of the working environment, and reducing potential pollution to the environment and personnel. Furthermore, auger conveying also has the advantages of smaller space occupation and faster feeding speed, making the work area cleaner and more efficient. Auger-type feeding machines excel in reducing manpower and improving work efficiency, and are not limited by conveying height. However, the purchase and maintenance costs of this type of equipment are relatively high, especially for models using high-quality materials and precision components. In addition, when handling excessively wet, viscous, or heavy materials, auger-type automatic feeding machines may experience poor conveying or even blockage due to material adhering to the inner wall of the pipe.

[0004] In contrast, tracked automatic feeders utilize a belt conveyor system, renowned for their high loading speed and wide material adaptability. Their large-pitch storage troughs and patterned conveyor belts can meet the demands of large conveying volumes. However, tracked automatic feeders generate significant noise and dust pollution during operation, impacting the working environment. While they perform better in handling moist powders, they may still encounter difficulties conveying high-viscosity, non-uniformly agglomerated powders (hereinafter referred to as: high-viscosity solid powders) due to material adhesion to the gaps between the conveyor belt and the equipment. Furthermore, tracked automatic feeders typically require more powerful power and more complex structural designs, and occupy a larger area, thus limiting their application in situations with poor ground conditions or limited space.

[0005] In view of the above, it is particularly important and urgent to develop a new type of automatic feeder that integrates small footprint, simple structure, high durability, non-clogging, and can effectively solve the feeding problem of this high-viscosity solid powder. Summary of the Invention

[0006] To address the shortcomings of current technologies, this invention, based on existing technologies and practical applications, provides a feeding device suitable for high-viscosity, solid, unevenly agglomerated powdery materials.

[0007] The technical solution of the present invention is as follows:

[0008] According to one aspect of the present invention, a feeding device suitable for high-viscosity solid non-uniform agglomerated powder materials is provided, comprising: a feeding elevator, a pushing mechanism, and a dispensing and metering mechanism;

[0009] The feeding elevator includes an elevator frame, a material box fixing frame, a material box clamping assembly, a guide assembly, a lifting and tilting plate, and a transmission and lifting assembly. The material box clamping assembly is used to fix the transfer material box to the material box fixing frame. One end of the material box fixing frame is rotatably engaged with the lifting and tilting plate. The transmission and lifting assembly is used to drive the material box fixing frame to rise and fall along the elevator frame. When the elevator frame rises to the curved part of the guide assembly, it automatically tilts and pours out the high-viscosity solid powder in the transfer material box under the cooperation of the guide assembly and the lifting and tilting plate.

[0010] The pushing mechanism is located on one side of the feeding elevator. The pushing mechanism includes a receiving hopper, a pushing bin, a scraper connected to the pushing motor, a front bin door, and a rear bin door. Both the front bin door and the rear bin door can be raised and lowered. The scraper can move up and down with the rear bin door. The scraper is used to push out the powder in the pushing bin one by one through reciprocating back and forth movement.

[0011] The material dispensing and metering mechanism is located on one side of the pushing mechanism. The material dispensing and metering mechanism includes a vibration component, a metering dispensing component, and a conveyor belt component. The vibration component is used to receive the powder pushed out by the pushing mechanism and vibrate and disperse it before conveying it to the metering dispensing component. The metering dispensing component is used to weigh and meter the dispensing material and then transfer it to a storage container located on the conveyor belt component.

[0012] Furthermore, the guiding assembly includes an inner guide rail and an outer guide rail fixed to the side of the elevator frame near the pushing mechanism. The inner guide rail is vertically arranged, and the outer guide rail is vertically arranged with its top gradually curving outward to a horizontal shape.

[0013] A bracket is fixedly installed on the upper part of one side of the material box fixing frame. An outer guide wheel is installed on the bracket and runs along the outer guide rail. The lower part of one side of the material box fixing frame is rotatably connected to the lifting and tilting plate through the main shaft. An inner guide wheel is installed on the lifting and tilting plate and runs along the inner guide rail. The lifting and tilting plate is connected to the transmission lifting assembly.

[0014] Furthermore, the material box clamping assembly includes a fixed drive motor, a fixed plate, and a clamping drive motor. The fixed drive motor and the fixed plate are disposed on the top of the material box fixing frame. The fixed plate is used to press the transfer material box downward under the action of the fixed drive motor. The clamping drive motor is disposed at the bottom of the material box fixing frame and is used to clamp the transfer material box from the bottom.

[0015] Furthermore, the scraper is located at the top of the rear hopper door. The pusher motor drives the scraper to reciprocate along the guide rail via gears and racks. The front hopper door is equipped with a guide rail slider and is driven to rise and fall by the front hopper door drive motor. The rear hopper door is equipped with a guide rail slider and is driven to rise and fall by the rear hopper door drive motor. After each layer of powder is scraped out, the front hopper door and the rear hopper door move downward by one scraper height and make the upper surface of the front hopper door flush with the bottom surface of the scraper.

[0016] Furthermore, the vibration assembly includes a scoop-shaped vibrating hopper, a vibration mechanism frame, and a vibrator. The vibrating hopper is placed on top of the vibration mechanism frame, and the vibrator is located at the bottom of the vibrating hopper. The powder in the vibrating hopper is dispersed by high-frequency vibration.

[0017] Furthermore, the quantitative dispensing component includes a quantitative hopper, which is fixed above the dispensing component frame by a weighing module;

[0018] The metering hopper includes two hinges arranged in a V-shape and metal plates on both sides. The hinges are controlled to open and close by a hinge motor. When the hinges are open, the metering hopper drops material downwards.

[0019] Furthermore, the dispensing and metering mechanism also includes a compaction component, which is located behind the dispensing and metering component. The compaction component includes a compaction component frame, a compaction plate, and a compaction drive component. The compaction drive component is connected to the compaction plate and is used to drive the compaction plate to move downward to compact the powder in the storage container.

[0020] Furthermore, the conveyor belt assembly includes a conveyor belt that passes through the quantitative dispensing assembly and the compaction assembly. The conveyor belt is used to transport storage containers, and there are limiting guide wheels on both sides of the conveyor belt.

[0021] Furthermore, a dispensing limit plate is provided at the quantitative dispensing component, and the dispensing limit plate is driven by a dispensing limit drive motor to limit the storage container at the quantitative dispensing component. A compaction limit plate is provided at the compaction component, and the compaction limit plate is driven by a compaction limit drive motor to limit the storage container at the compaction component.

[0022] According to another aspect of the present invention, a feeding method for the above-mentioned feeding equipment suitable for high-viscosity solid non-uniformly agglomerated powdery materials is provided, comprising the following steps:

[0023] 1) The transfer box filled with high-viscosity solid powder is transferred to the feeding elevator position and placed into the box fixing frame from one side. The box clamping assembly fixes the transfer box to the box fixing frame. The transmission lifting assembly is started to drive the box fixing frame and the transfer box to rise. When it rises to the bending position of the guide assembly, the box fixing frame drives the transfer box to flip together in the direction of the pushing mechanism to dump the powder.

[0024] 2) When the powder is loaded to a certain height in the feeding hopper, the feeding elevator stops tilting, the front hopper door drops by one scraper height, the scraper moves forward, cuts the large pieces of powder and pushes them to the dispensing and metering mechanism. After the scraper completes one reciprocating motion, the front hopper door and the rear hopper door drop to the same height, and the scraper continues to make one reciprocating motion until the front hopper door is completely lowered.

[0025] 3) After being dispersed by the vibration component, the powder falls into the quantitative dispensing component. After being accurately weighed, the lower hinge of the quantitative dispensing component is opened by the motor, allowing the powder to fall into the storage container. The storage container moves with the conveyor belt, completing the automated quantitative powder filling process.

[0026] 4) The storage container is transferred to the compaction assembly, and the entire process is completed after compaction.

[0027] The beneficial effects of this invention are:

[0028] High-viscosity solid non-uniformly agglomerated powder material (hereinafter referred to as: high-viscosity solid powder) is transported from the material box to the top of the pusher hopper through an innovative elevator and poured into the pusher hopper. It adopts a non-auger and crawler feeding structure, which occupies less space and can be adapted to most spaces and environments. Moreover, the equipment does not contain an enclosed space, which facilitates cleaning and replacement of high-viscosity solid powder with different compositions and batches.

[0029] The push-plate type hopper for material distribution avoids the blockage problems encountered in auger-type conveying of high-viscosity solid powder and the adhesion problems encountered in track-type conveying of high-viscosity solid powder. Furthermore, when using the aforementioned feeder to convey high-viscosity solid powder, dust pollution is minimal, and its environmental impact is negligible. The push-plate type feeding mechanism prevents large pieces of high-viscosity solid powder from clogging the conveying route. The push-plate cutting and scraping mechanism, along with the vibrating hopper, breaks down large pieces of high-viscosity solid powder, facilitating transportation and subsequent processes.

[0030] A weighing sensor is installed below the discharge port of the pusher-type hopper to ensure the stable and continuous feeding of high-viscosity solid powder into the designated carrier (storage container or transfer container). It is easy to operate manually, facilitates the switching of material batches and cleaning equipment. The high-viscosity solid powder is crushed by the vibrating screen and will not stick together when there is no external force to compact it. The quality of high-viscosity solid powder delivered to the bottom is the same each time, and the output quality of high-viscosity solid powder is stable.

[0031] The equipment has a reasonable overall layout and a controllable production line at the bottom, which can be combined with other kilns, packaging, injection molding or crushing devices to form an automated production line. Attached Figure Description

[0049] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0050] This invention provides a feeding device suitable for high-viscosity, solid, non-uniformly agglomerated powder materials. It primarily addresses the problems of conveying and quantitatively dispensing high-viscosity, solid, non-uniformly agglomerated powder materials, overcoming their physical defects such as easy adhesion to other materials, easy agglomeration during extrusion, and easy intrusion during the conveying process.

[0051] refer to Figure 1 As shown in the figure, the feeding equipment in this embodiment mainly includes: a feeding elevator 1, a pushing mechanism 2, a vibration component 3, a quantitative dispensing component 4, and a compaction component 5.

[0052] Among them, the feeding elevator 1 is as follows Figure 2 , Figure 3 , Figure 4 As shown, it mainly consists of a lifting drive motor 11, a lifting frame 12, a transfer hopper 13, a hopper fixing frame 14, a transmission lifting assembly 15, a lifting tilting plate 110, and a guiding assembly. An outer guide rail 16 and an inner guide rail 111 are fixedly installed on the outer side of the lifting frame 12 near the pushing mechanism 2. The lifting drive motor 11 is located at the top of this side. The inner guide rail 112 is vertically arranged, and the outer guide rail 16 is vertically arranged, but its top gradually curves outward to a horizontal shape, as shown in the figure.

[0053] The material box fixing frame 14 is located at the bottom inner side of the elevator frame 12. One side of the material box fixing frame 14 has an opening for pushing in the transfer material box 13. An outer guide wheel 111 is located on the upper part of one side of the material box fixing frame 14. The outer guide wheel 111 is located within the outer guide rail 16 and can run along the outer guide rail 16. A main shaft is connected to the lower side of the material box fixing frame 14, and both ends of the main shaft are rotatably engaged with the lifting tilting plate 110. Two inner guide wheels 113 are located on the outer side of the lifting tilting plate 110. The inner guide wheels 113 are located within the inner guide rail 111 and can run along the inner guide rail 111.

[0054] The transmission lifting assembly 15 mainly consists of sprockets and metal chains. It is used to connect the lifting drive motor 11 and the lifting tilting plate 110. When the lifting drive motor 11 runs, it drives the lifting tilting plate 110 to rise. The lifting tilting plate 110 drives the material box fixing frame 14 to rise. When the outer guide wheel 111 connected to the material box fixing frame 14 runs to the curved part at the top of the outer guide rail 16, it can no longer move upward. It can only move gradually towards the horizontal direction according to the shape of the outer guide rail 16. At this time, when the lifting tilting plate 110 continues to move upward along the inner guide rail 112, the material box fixing frame 14 will rotate around the main shaft, thereby driving the transfer material box 13 to tilt and rotate, realizing the dumping of powder in the material box.

[0055] In this embodiment, to ensure the stability of the transfer box 13, a box clamping assembly is provided to securely fix the transfer box 13 within the box fixing frame 14. Specifically, the box clamping assembly mainly includes a fixed drive motor 17, a fixing plate 18, and a clamping drive motor 19. The fixed drive motor 17 and the fixing plate 18 are arranged above the box fixing frame 14 on the side away from the guide rail assembly. The fixing plate 18 is connected to the fixed drive motor 17. The fixed drive motor 17 drives the fixing plate 18 downward, pressing the transfer box 13 onto the box fixing frame 14 from above through the fixing plate 18 to prevent the box from falling off. The clamping drive motor 19 is located below the box fixing frame 14, assisting in fixing and limiting the lower part of the box.

[0056] In one specific embodiment provided in this example, the lifting drive motor 11 is located at the top of the lifting frame 12, and controls the up and down lifting motion of the material box fixing frame 14 through a large ratio reducer and a double chain structure.

[0057] In one specific embodiment provided in this example, two fixed drive motors 17 and two clamping drive motors 19 are respectively provided to ensure the stability of the transfer box 13 and prevent it from falling off.

[0058] In one specific embodiment provided in this example, a metal protective net is installed around the frame of the feeding elevator 1 to reduce the hazards caused by the tilting of the material box and ensure production safety.

[0059] The feeding mechanism 2 in this embodiment is as follows: Figure 5 , Figure 6 As shown. It mainly includes a receiving hopper 21, a front hopper door 22, a pushing mechanism frame 23, a front hopper door drive motor 24, a pushing hopper 25, a pushing motor 26, a scraper 27, a rear hopper door 28, a metal protective net 29, and a rear hopper door drive motor 210.

[0060] Metal protective nets 29 are provided on both sides of the pushing mechanism frame 23. The front door drive motor 24 and the rear door drive motor 210 are servo motors located inside the skeleton of the pushing mechanism frame 23. They are used to drive the lifting and lowering movements of the front hopper door 22 and the rear hopper door 28, respectively. At the same time, both the front hopper door 22 and the rear hopper door 28 are equipped with guide rail sliders to ensure the flexibility and positioning accuracy of the lifting and lowering movements. The upper inner side of the pushing mechanism frame 23 is the pushing hopper 25. The front hopper door 22 and the rear hopper door 28 are located on the front and rear sides of the pushing hopper 25. The receiving hopper 21 is located above the pushing hopper 25. The scraper 27 is set on the top of the rear hopper door 28. The pushing motor 26 is located on the upper outer side of the scraper 27. The pushing motor 26 drives the scraper 27 through gear and rack movement.

[0061] After feeding, the front hopper door 22 descends, and the scraper 27 is now higher than the front hopper door 22. The scraper 27 moves forward to push the high-viscosity solid powder in the feeding hopper 25 from the front to the next mechanism. After the scraper 27 returns, the hopper door 28 moves downward together, and the front hopper door 22 also moves downward. Each movement is the height of one scraper 27. Through the reciprocating motion of the scraper 27 and the hopper door 2, the powder is conveyed downward layer by layer. During this process, the scraper 27 can cut the powder and break up the clumps of powder.

[0062] The material dispensing and metering mechanism is attached. Figure 7 As shown, it mainly includes a vibration component 3, a quantitative dispensing component 4, and a compaction component 5.

[0063] The vibration component 3 in this embodiment is as shown in the attached figure. Figure 8 As shown, it mainly includes a vibrating hopper 31, a vibrating mechanism frame 32, and a vibrator 33. The vibrating hopper 31 is placed on top of the vibrating mechanism frame 32, and the vibrator 33 is located at the bottom of the hopper 31 and inside the vibrating mechanism frame 32. High-frequency vibration disperses highly viscous solid powder, facilitating quantitative distribution. Furthermore, in a specific embodiment provided in this example, the frequency of the vibrator 33 is 10-25 Hz, preferably 15 Hz, and the vibrating hopper 31 adopts a scoop-shaped hopper for convenient material feeding.

[0064] Quantitative dispensing component 4 as shown in the attached document Figure 9 and attached Figure 10As shown, the main components include a quantitative hopper 41, a weighing module 42, a hinge motor 43, a dispensing component frame 44, a dispensing limit drive motor 45, a conveyor belt 46, a storage container 47, and a dispensing limit plate 48. The quantitative hopper 41 mainly consists of two V-shaped hinges 41-A and metal plates 41-B on both sides. Weighing modules 42 are located on both sides of the metal plates 41-B for accurate weighing. The quantitative hopper 41 is fixed above the dispensing component frame 44 via the weighing modules 42. The hinge motor 43 is located on one side of the metal plates 41-B and controls the opening and closing of the hinges 41-A via a linkage structure. A through-type conveyor belt 46 is located below the dispensing mechanism frame 44, through which the storage container 47 is transported. The dispensing limit plate 48 is located on the dispensing component frame 44 on the outer bottom of the quantitative hopper 41 in the forward direction of the conveyor belt 46, and is arranged horizontally with the conveyor belt 46. The dispensing limit drive motor 45 is mounted on the dispensing component frame 44 on the outer side of the dispensing limit plate 48 in the parallel direction. The dispensing limit plate 48 and the dispensing limit drive motor 45 are used to control the positioning of the storage container 47. In a specific embodiment provided in this example, the above-mentioned quantitative hopper 41 is made of highly polished stainless steel or coated with a high-smoothness layer. The weighing module 2 is a high-precision weight sensor with a weighing error of one-thousandth.

[0065] Compaction component 5 as attached Figure 11 As shown, the system mainly includes a compaction component frame 51, a compaction limiting plate 52, a compaction plate 53, a compaction limiting drive motor 54, and a compaction drive motor 55. The compaction drive motor 55 is connected to the compaction plate 53 and can drive the compaction plate 53 to move up and down, thereby compacting the powder in the storage container 47 on the conveyor belt 46. The compaction component frame 51 is also penetrated by the conveyor belt 46. The compaction limiting plate 52 is set on the compaction component frame 51 in the forward direction of the conveyor belt 46 and is arranged perpendicular to the conveyor belt 46. The compaction limiting drive motor 54 is located on the compaction component frame 51 directly above the compaction limiting plate 52. The compaction limiting plate 52 enables precise positioning of the storage container 47 on the conveyor belt 46.

[0066] This embodiment also provides a feeding method for the above-mentioned feeding equipment, mainly as follows:

[0067] When the equipment is in the ready state, the transfer box 13 is placed in the box fixing frame 14 at the bottom of the feeding elevator 1. The equipment automatically senses and drives the fixed drive motor 17 and the clamping drive motor 19 to fix the position of the transfer box 13.

[0068] The drive motor 11 starts working and raises the position of the transfer box 13. When the transfer box 13 is raised to the set height, the outer guide rail 16 flips outward and the outer guide wheel 111 moves outward. The transfer box 13 tilts to the side and transfers the high-viscosity solid powder inside to the pusher hopper 25.

[0069] After the feeding hopper 25 receives a certain amount of highly viscous solid powder, the front hopper door 22 is lowered to a certain height under the control of the front hopper door drive motor 24. This height is the same as the height of the scraper 27, which facilitates the scraper 27 to push the material to the next stage. The scraper 27 is controlled by the feeding motor 26 to perform one reciprocating motion. Subsequently, the front hopper door 22 and the rear hopper door 28 are simultaneously controlled to lower to the same height, which is the same as the height of the scraper 27. The feeding motor 26 drives the scraper 27 again to perform one reciprocating motion, realizing a second feeding. The above actions are repeated until the powder in the feeding hopper 25 is completely transferred. During the feeding process, large pieces of viscous powder can be cut to reduce the degree of powder adhesion.

[0070] High-viscosity solid powder is transferred from the feed hopper 25 to the vibration component 3. High-frequency vibration can further disperse the powder and reduce large solid powder particles. The vibrating hopper 31 adopts a scoop shape to transfer the powder to the quantitative dispensing component 4.

[0071] After receiving the powder, the quantitative hopper 41 accurately measures the powder mass through the weighing module 42. Once the mass is reached, the material distribution limit drive motor 45 starts, and the material distribution limit plate 48 moves forward to control the storage container 47 to be fixed below the quantitative hopper 41. The hinge motor 43 starts, and the hinge 41-A of the quantitative hopper 41 opens, transferring the powder to the storage container 47. After a fixed time, the hinge 41-A closes, the material distribution limit drive motor 45 starts, and the material distribution limit plate 48 is retracted. The storage container 47 then continues to transfer the powder to the compaction component 5.

[0072] When the material distribution limit plate 48 is retracted, the compaction limit drive motor 54 starts, moving the compaction limit plate 52 downward to control the position of the storage container 47 directly below the compaction plate 53. When the storage container 47 touches the compaction limit plate 52, the pressure sensor in the compaction limit plate 52 transmits a signal to the compaction drive motor 55, and the compaction component 5 performs compaction work. The compaction drive motor 55 drives the compaction plate 53 to compact the powder in the storage container 47. After compaction is completed, the compaction limit drive motor 54 starts, retracts the compaction limit plate 52, and the work is completed.

9. A feeding method for a feeding device according to any one of claims 1-8 suitable for high-viscosity, solid, non-uniformly agglomerated powdery materials, characterized in that, Includes the following steps: 1) The transfer box filled with high-viscosity solid powder is transferred to the feeding elevator position and placed into the box fixing frame from one side. The box clamping assembly fixes the transfer box to the box fixing frame. The transmission lifting assembly is started to drive the box fixing frame and the transfer box to rise. When it rises to the bending position of the guide assembly, the box fixing frame drives the transfer box to flip together in the direction of the pushing mechanism to dump the powder. 2) When the powder is loaded to a certain height in the feeding hopper, the feeding elevator stops tilting, the front hopper door drops by one scraper height, the scraper moves forward, cuts the large pieces of powder and pushes them to the dispensing and metering mechanism. After the scraper completes one reciprocating motion, the front hopper door and the rear hopper door drop to the same height, and the scraper continues to make one reciprocating motion until the front hopper door is completely lowered. 3) After being dispersed by the vibration component, the powder falls into the quantitative dispensing component. After being accurately weighed, the lower hinge of the quantitative dispensing component is opened by the motor, allowing the powder to fall into the storage container. The storage container moves with the conveyor belt, completing the automated quantitative powder filling process. 4) The storage container is transferred to the compaction component, and the entire process is completed after compaction.
