Description

Technical Field

[0001] The present invention mainly relates to the technical field related to feeding equipment, and specifically relates to a feeding equipment and method suitable for high-viscosity solid uneven agglomerated powdery materials. Background Art

[0002] As an advanced conveying equipment in the field of powder materials in China, the automatic feeder is particularly good at efficiently transporting powder to a high place and accurately filling it into the hopper of packaging machines, injection molding machines, crushers and other equipment. Its original design intention is to reduce the physical burden of workers and effectively curb the dust problem that may be generated during the powder addition process, thereby creating a cleaner and safer working environment.

[0003] At present, the mainstream automatic feeders on the market are mainly divided into crawler type and auger type. The auger type automatic feeder adopts a transmission and feeding method in which a motor drives the screw to rotate. The screw drives the material to rotate in a closed pipe to achieve material transportation, which effectively reduces dust leakage, improves the cleanliness of the working environment, and reduces the potential pollution of materials to the environment and personnel. In addition, the auger conveying method also has the advantages of small space occupation and fast feeding speed, making the working area cleaner and more efficient. The auger type feeder performs well in reducing the burden of manpower and improving work efficiency, and is not limited by the 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 the auger type automatic feeder handles materials that are too wet, sticky or heavy, the material may adhere to the inner wall of the pipe, resulting in poor transmission and even agglomeration and blockage.

[0004] In contrast, crawler-type automatic loaders use belt-type transmission and loading methods, and are known for their efficient loading speed and wide material adaptability. Its large-pitch storage trough and patterned conveyor belt design can meet the needs of large conveying volumes. However, the noise and dust pollution problems generated by crawler-type automatic loaders during operation are more prominent, which has a certain impact on the working environment. Although crawler-type automatic loaders perform better in handling wet powders, when conveying high-viscosity solid uneven agglomerated powder materials (hereinafter referred to as: high-viscosity solid powders), transportation difficulties may still occur due to the material sticking to the gap between the conveyor crawler and the equipment. In addition, crawler-type automatic loaders usually require more powerful power support and more complex structural designs, and occupy a larger area. Therefore, their application is subject to certain restrictions in situations where ground conditions are poor or space is limited.

[0005] In view of the above situation, it is particularly important and urgent to develop a new automatic feeder that has a small footprint, simple structure, strong durability, is not easy to clog, and can effectively solve the feeding problem of this high-viscosity solid powder. Summary of the invention

[0006] In order to solve the deficiencies of the current technology, the present invention combines the existing technology and provides a feeding device suitable for high-viscosity solid uneven agglomerated powdery materials from the perspective of practical application.

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

[0008] According to one aspect of the present invention, there is provided a feeding device suitable for high-viscosity solid uneven agglomerated powdery materials, comprising: a feeding elevator, a pushing mechanism and a material dividing and quantitative mechanism;

The material box clamping assembly is used to fix the transfer material box on the material box fixing frame. One end of the material box fixing frame is rotatably matched with the lifting flip plate. The transmission 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, the guide assembly and the lifting flip plate cooperate to automatically flip and dump the high-viscosity solid powder in the transfer material box.

[0010] The pushing mechanism is arranged on one side of the feeding elevator, and includes a material receiving hopper, a pushing bin, a scraper connected to a pushing motor, a front bin door and a rear bin door.

[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 arranged 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 arranged at the bottom of the material box fixing frame for clamping the transfer material box from the bottom.

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

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

[0017] Furthermore, the quantitative material distribution component includes a quantitative hopper, which is fixed above the material distribution component frame through a weighing module;

[0018] The quantitative hopper includes two hinges arranged in a V shape and metal plates on both sides. The hinges are opened and closed by a hinge motor. When the hinges are opened, the quantitative hopper drops materials downward.

[0019] Furthermore, the quantitative material distribution mechanism also includes a compaction component, which is arranged behind the quantitative material distribution 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 to drive the compaction plate to move downward to compact the powder in the storage container.

[0020] Furthermore, the conveyor belt assembly includes a transmission belt, which passes through the quantitative material distribution assembly and the compaction assembly.

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

[0023] 1) The transfer box filled with high-viscosity solid powder is transferred to the loading elevator position and placed into the box fixing frame from one side. The transfer box is fixed to the box fixing frame through the box clamping assembly. 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 toward the pushing mechanism to dump the powder;

[0024] 2) When the powder is loaded to a certain height in the push bin, the loading elevator stops dumping, the front bin door drops by a scraper height, the scraper moves forward, cuts the large pieces of powder and pushes them to the material dividing and quantitative mechanism, after the scraper completes a reciprocating motion, the front bin door and the rear bin door drop to the same height, the scraper continues to make a reciprocating motion until the front bin door is completely lowered;

[0025] 3) The powder is dispersed by the vibration component and falls into the quantitative distribution component. After accurate weighing, the hinge on the lower side of the quantitative distribution component is opened by the motor, so that the powder falls into the storage container. The storage container moves with the conveyor belt to complete the automatic quantitative loading of the powder.

[0026] 4) The storage container is transferred to the compacting assembly, where compaction completes the entire job.

[0027] Beneficial effects of the present invention:

[0028] High-viscosity solid uneven agglomerated powdery materials (hereinafter referred to as: high-viscosity solid powdery materials) are transported to the top of the pusher bin through an innovative elevator in the material box and poured into the pusher bin. It adopts a non-auger and crawler feeding structure, occupies a small space, and can adapt to most spaces and environments. The equipment does not contain closed spaces, which is convenient for cleaning and replacement of high-viscosity solid powdery materials of different compositions and batches.

[0029] The use of push-plate silo material separation avoids blockage during the auger-type transmission of high-viscosity solid powder and avoids the adhesion problem during the crawler-type transmission of high-viscosity solid powder. In addition, when the above-mentioned feeder is used to transmit high-viscosity solid powder, the dust pollution is small and there is no need to consider the environmental pollution caused by it. The use of push-plate pushers avoids large pieces of high-viscosity solid powder blocking the transmission route, and through push-plate scraping and vibration hoppers, large pieces of high-viscosity solid powder can be broken up, which is convenient for transportation and the next process.

[0030] A weighing sensor is installed below the discharge port of the push-plate silo to ensure stable and continuous delivery of high-viscosity solid powder into a predetermined carrier (storage container or transmission container). It is easy for manual operation and convenient for switching material batches and cleaning equipment. The high-viscosity solid powder is crushed by the vibrating screen and will not stick together without external compaction. The quality of the high-viscosity solid powder transported to the bottom is the same each time, and the quality of the output high-viscosity solid powder is stable.

[0031] The overall layout of the equipment is reasonable, with a controllable assembly line set up below, which can be combined with other kilns, packaging, injection molding or crushing devices to form an automatic production line. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the application.

[0050] The embodiment of the present invention provides a feeding device suitable for high-viscosity solid uneven agglomerated powder materials. It mainly aims at the problem of conveying and quantitative packaging of high-viscosity solid uneven agglomerated powder materials, and overcomes the physical property conveying defects of easy adhesion with other materials, easy agglomeration by extrusion, and easy invasion during conveying.

[0051] refer to Figure 1 As shown in the figure, the feeding equipment of this embodiment mainly includes: a feeding elevator 1, a pushing mechanism 2, a vibration component 3, a quantitative distribution 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 is mainly composed of a lifting drive motor 11, a lifting machine frame 12, a transfer material box 13, a material box fixing frame 14, a transmission lifting component 15, a lifting flip plate 110, a guide component, etc. The outer side of the lifting machine frame 12 near the pushing mechanism 2 is fixed with an outer guide rail 16 and an inner guide rail 111. The top of this side is provided with a lifting drive motor 11. The inner guide rail 112 is vertically arranged, and the outer guide rail 16 is vertically arranged, but the top thereof is gradually bent outward to be horizontal, as shown in the figure.

[0053] The material box fixing frame 14 is arranged at the inner bottom of the lifting machine frame 12, and one side of the material box fixing frame 14 has an opening for pushing the transfer material box 13. The upper part of one side of the material box fixing frame 14 has an outer guide wheel 111, which is located in the outer guide rail 16 and can run along the outer guide rail 16. One side of the lower part of the material box fixing frame 14 is connected to a main shaft, and both ends of the main shaft are rotatably matched with the lifting flip plate 110. There are two inner guide wheels 113 on the outer side of the lifting flip plate 110, respectively, and the inner guide wheels 113 are located in the inner guide rail 111 and can run along the inner guide rail 111.

[0054] The transmission lifting component 15 is mainly composed of a sprocket and a metal chain, which is used to connect the lifting drive motor 11 and the lifting flip plate 110. When the lifting drive motor 11 is running, it drives the lifting flip plate 110 to rise, and the lifting flip 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 and can only gradually move in the horizontal direction along the shape of the outer guide rail 16. At this time, when the lifting flip plate 110 continues to move upward along the inner guide rail 112, the material box fixing frame 14 will flip around the main axis, thereby driving the transfer material box 13 to tilt and flip, and realize the dumping of the powder in the material box.

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

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

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

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

[0059] The push mechanism 2 of this embodiment is as follows Figure 5 , Figure 6 It mainly includes a receiving hopper 21, a front silo door 22, a pushing mechanism frame 23, a front silo door driving motor 24, a pushing silo 25, a pushing motor 26, a scraper 27, a rear silo door 28, a metal protection net 29, and a rear silo door driving motor 210.

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

[0061] After feeding, the front silo door 22 descends, and the scraper 27 is now higher than the position of the front silo door 22. The scraper 27 moves forward to push the high-viscosity solid powder in the push silo 25 from the front to the next mechanism. After the scraper 27 returns, the silo door 28 moves downward together, and the front silo door 22 also moves downward at the same time, each time moving the height of the scraper 27. The scraper 27 reciprocates and cooperates with the silo door 2 to transport the powder downward layer by layer. In this process, the scraper 27 can cut the powder to break up the agglomerated powder.

[0062] The quantitative distribution mechanism is as follows Figure 7 As shown, it mainly includes a vibration component 3, a quantitative distribution component 4 and a compaction component 5.

[0063] The vibration assembly 3 of this embodiment is shown in the attached 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 the 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-viscosity solid powder is dispersed by high-frequency vibration to facilitate quantitative measurement. Further, in a specific implementation provided in this embodiment, the frequency of the vibrator 33 is 10-25HZ, preferably 15Hz, and the vibrating hopper 31 adopts a dustpan-shaped hopper to facilitate material discharge.

[0064] Quantitative material distribution component 4 as attached Fig. 9 and attached Fig.10As shown, it mainly includes a quantitative hopper 41, a weighing module 42, a hinge motor 43, a material distribution component frame 44, a material distribution limit drive motor 45, a conveyor belt 46, a storage container 47, and a material distribution limit plate 48. The quantitative hopper 41 is mainly composed of two V-shaped hinges 41-A and metal plates 41-B on both sides thereof. Weighing modules 42 are arranged on both sides of the metal plate 41-B to accurately weigh the mass. The quantitative hopper 41 is fixed above the material distribution component frame 44 through the weighing module 42. The hinge motor 43 is arranged on one side of the metal plate 41-B, and the opening and closing of the hinge 41-A is controlled by a connecting rod structure. A through-type conveyor belt 46 is arranged below the material distribution mechanism frame 44, and the storage container 47 is transmitted through the conveyor belt 46. The material distribution limit plate 48 is arranged on the material distribution component frame 44 at 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 material distribution limit drive motor 45 is arranged on the material distribution component frame 44 outside the parallel direction of the material distribution limit plate 48. The material distribution limit plate 48 and the material distribution limit drive motor 45 are used to control the positioning of the storage container 47. In a specific implementation provided in this embodiment, the quantitative hopper 41 is made of highly polished stainless steel or coated with a highly smooth layer. The weighing module 2 is a high-precision weight sensor with a weighing error of one thousandth.

[0065] Compacting assembly 5 as attached Fig.11 As shown, it mainly includes a compaction component frame 51, a compaction limit plate 52, a compaction plate 53, a compaction limit 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 to compact the powder in the storage container 47 on the conveyor belt 46. The interior of the compaction component frame 51 is also penetrated by the conveyor belt 46. The compaction limit plate 52 is arranged on the compaction component frame 51 in the forward direction of the conveyor belt 46 and is arranged vertically with the conveyor belt 46. The compaction limit drive motor 54 is located on the compaction component frame 51 directly above the compaction limit plate 52, and the storage container 47 is accurately positioned on the conveyor belt 46 through the compaction limit plate 52.

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

[0067] When the equipment is in a ready state, the transfer box 13 is placed in the box fixing frame 14 at the bottom of the loading elevator 1, and 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 lifting drive motor 11 starts working to raise the position of the transfer box 13. When the transfer box 13 is lifted to a set height, the outer guide rail 16 flips outward, the outer guide wheel 111 moves outward, and the transfer box 13 tilts sideways to transfer the high-viscosity solid powder inside to the pushing bin 25.

[0069] After the pushing silo 25 receives a certain amount of high-viscosity solid powder, the front silo door 22 is controlled by the front silo door driving motor 24 to drop to a certain height, which is the same as the height of the scraper 27, so that the scraper 27 can push the material to the next stage. The scraper 27 is controlled by the pushing motor 26 to make a reciprocating motion. Subsequently, the front silo door 22 and the rear silo door 28 are simultaneously controlled to drop to the same height, which is the height of the scraper 27. The pushing motor 26 drives the scraper 27 again to make a reciprocating motion to achieve secondary pushing. The above action is repeated until the powder in the pushing silo 25 is transmitted. During the pushing process, large pieces of sticky powder can be cut to reduce the degree of powder adhesion.

[0070] High-viscosity solid powder is transferred from the pushing bin 25 to the vibration component 3 . High-frequency vibration can further disperse the powder and reduce large pieces of solid powder. The vibration hopper 31 is in the shape of a dustpan and is used to transfer the powder to the quantitative distribution component 4 .

[0071] After the metering hopper 41 receives the powder, the weighing module 42 accurately measures the mass of the powder. When the mass is reached, the material distribution limit drive motor 45 is started, and the material distribution limit plate 48 moves forward to control the storage container 47 to be fixed under the metering hopper 41. The hinge motor 43 is started, and the hinge 41-A of the metering hopper 41 is opened to transfer the powder to the storage container 47. After a fixed time, the hinge 41-A is closed, and the material distribution limit drive motor 45 is started to withdraw the material distribution limit plate 48, and the storage container 47 continues to be transferred to the compaction component 5.

[0072] When the material distribution limit plate 48 is withdrawn, the compaction limit drive motor 54 is started, and the compaction limit plate 52 is moved downward to control the position of the storage container 47 to be 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 assembly 5 performs compaction work. The compaction drive motor 55 drives the compaction plate 53 to compact the powder in the storage container 47. After the compaction is completed, the compaction limit drive motor 54 is started, and the compaction limit plate 52 is withdrawn to complete the work.
