Description

Technical Field

[0001] The present invention relates to the technical field of feeding equipment, and specifically to a feeding device for industrial manufacturing material production. Background Art

[0002] In the field of industrial manufacturing, ceramic powders are a type of basic material with excellent properties and wide applications. These powders are prepared by processes such as grinding and synthesis from various inorganic non-metallic compounds such as alumina, zirconia, and silicon carbide, and have characteristics such as high hardness, high temperature resistance, corrosion resistance, and good insulation. Different types of ceramic powders are suitable for different scenarios. For example, alumina powder is commonly used in manufacturing ceramic cutting tools and integrated circuit substrates; zirconia powder, with good toughness and wear resistance, is widely used in dental prostheses and ceramic bearings; silicon carbide powder, with high thermal conductivity, plays an important role in the field of semiconductor heat dissipation. However, during the feeding process of ceramic powders, problems such as agglomeration, poor fluidity, and static charge accumulation are likely to occur, and targeted technical improvements are required to ensure their efficient and stable application.

[0003] Ceramic powder particles have a small particle size, a large specific surface area, and a high surface energy, making them prone to agglomeration. Agglomerated ceramic powder particles will affect the uniformity and accuracy of feeding, resulting in non-uniform material properties during subsequent processing. For example, during the sintering process of ceramic cutting tools, pores or density non-uniformities may appear around the agglomerates, thus affecting the density and mechanical properties of the ceramic cutting tools. Moreover, the shapes of ceramic powder particles are irregular and the surfaces are rough. In addition, there are interactions such as van der Waals forces and electrostatic forces between the particles, making their fluidity poor. This will lead to problems such as poor feeding and blocked pipelines during the feeding process, affecting production efficiency and increasing equipment maintenance costs. Therefore, those skilled in the art have proposed a feeding device for industrial manufacturing material production to solve the above-mentioned technical problems. Summary of the Invention

[0021] Working principle: When processing ceramic cutting tools or integrated circuit substrates in industrial manufacturing, first, the powder dispersion mechanism is started. The ceramic powder is transported through the feeding equipment and enters the trapezoidal cavity through the feeding pipe on the front end box for temporary storage and collection. Then, when the ceramic powder in the trapezoidal cavity is collected and stored to a certain extent, the ceramic powder at the bottom of the trapezoidal cavity enters the corresponding discharge grooves respectively and fills them up. After that, the second driving motor on the front end box is started. When the second driving motor is started, the rotating shaft on it drives the blanking roller at the bottom of the trapezoidal cavity to rotate. While the blanking roller is rotating, it drives the discharge grooves filled with ceramic powder above it to rotate synchronously, so that the discharge grooves transfer the ceramic powder filled in them while rotating. After the ceramic powder in the discharge grooves breaks away from the limit of the trapezoidal cavity, the ceramic powder in the discharge grooves pours out and scatters from it. Then, the first driving motor on the front end box is started. When the rotating shaft of the first driving motor rotates, it drives the rotating seat on it to rotate synchronously. While the rotating seat is rotating, it drives the turning and scraping plate on it to rotate synchronously. While the turning and scraping plate is rotating, it scatters and disperses the agglomerated ceramic powder during the falling process, and at the same time picks up and turns over the ceramic powder falling on the bottom of the front end box, so as to scatter and disperse the ceramic powder again and facilitate the subsequent dispersion and conveying processes. At the same time, the acoustic wave generator on the mounting seat is started. When the acoustic wave generator is started, it generates acoustic waves. The acoustic waves generated enter the diffusion flow channel in the mounting seat for diffusion and amplification. Then, the amplified acoustic waves are distributed through the distribution cavity on the mounting seat onto the rubber diaphragm on the fixed frame. The rubber diaphragm excited by the acoustic waves synchronously vibrates the air in the space of the front end box. And the acoustic wave transmission part generates laminar mixing of the ceramic powder distributed in the air in the front end box while being vibrated, and at the same time also breaks up the smaller agglomerated powder floating in the air, thus completing the conveying and multiple dispersion processing of the ceramic powder;Then the powder conveying mechanism is started. First, the nitrogen generator on the front end box is started. While starting, the nitrogen generator conveys the generated nitrogen into the installation box through the connecting pipe. After the nitrogen enters the drying chamber in the installation box, the heating wire on the installation rod is electrified to generate heat, heating and drying the nitrogen in the drying chamber. Then the nitrogen after heating and drying enters the front end box and is mixed with the ceramic powder therein. At the same time, the axial flow fan on the rear end box is started. While starting, the axial flow fan pumps the air in the rear end box. While the air in the rear end box flows out, it guides the ceramic powder mixed with nitrogen in the front end box to enter the rear end box through the conveying box. When the ceramic powder mixed with nitrogen in the front end box enters the inside of the conveying box, the ceramic powder mixed with nitrogen is limited in flow rate through multiple staggered slots on the variable speed plate at the starting end in the conveying box, thereby reducing the flow rate of the ceramic powder entering the conveying box. When the ceramic powder mixed with nitrogen flows to the middle of the conveying box, its high flow rate is restored again. Then when the ceramic powder mixed with nitrogen in the conveying box is conveyed to its terminal end, the ceramic powder in the flowing process is limited in flow rate and decelerated again through the staggered slots on the variable speed plate in the terminal end of the conveying box, so as to complete the variable speed conveying process of the ceramic powder during transportation. After that, the conveying and collecting mechanism is started. When the ceramic powder conveyed by the powder conveying mechanism enters the rear end box, with the continuous entry of the ceramic powder mixed with nitrogen, the ceramic powder mixed with nitrogen sequentially passes through the collecting screen plates on the mounting frames at various positions and is collected and intercepted by the collecting screen plates. At the same time, excited by the sound wave of the sound wave generator on the front end box, the ceramic powder attached to the surface of the collecting screen plates at various positions vibrates and separates, and then the ceramic powder vibrated and separated from the collecting screen plates and the powder separated and collected layer by layer fall into the conical cavity in the base through the V-shaped cavity on the partition seat for centralized collection. Then when it is used for industrial processing again, the pumping pump on the rear end box is started. The pumping pump conveys and discharges the ceramic powder collected in the conical cavity through the connecting pipe for use in industrial manufacturing and processing, so as to complete the collection and re-conveyance process of the ceramic powder after transportation; at the same time, the static electricity elimination mechanism is started. When the powder conveying mechanism conveys the ceramic powder, the carbon-based coating provided on the inner wall of the conveying box reduces the friction during the conveying and moving process of the powder, and then the static electricity generated during the powder conveying process is conducted to the metal powder conductive coating on the surface of the conveying box through the conductive fiber network inside the conveying box. Then the static electricity conducted to the metal powder conductive coating is transmitted to the metal conductive layer on the substrate through the cooperation of the metal grounding wire and the connecting buckle seat at its bottom, and finally conducted to the ground through the substrate, so as to complete the elimination process of static electricity during the powder conveying process.;

[0022] The present invention provides a material production and feeding device for industrial manufacturing. It has the following beneficial effects:

[0023] 1. By adding and setting up a powder conveying mechanism, during the process of ceramic powder conveying, firstly, through a multiple dispersion and separation treatment mechanism, the problem of ceramic powder agglomeration can be effectively solved. The multi-stage dispersion components and air flow vibration dispersion components set inside this mechanism can mechanically break and impact the agglomerated powder in sequence, enabling the originally agglomerated powder particles to be fully separated and uniformly dispersed, thereby ensuring the uniformity of ceramic powder during subsequent processing, and avoiding quality defects such as surface pores and uneven density of products caused by uneven powder from the source. Secondly, the uniformly dispersed powder can more accurately fill the mold cavity during subsequent processing links such as forming and sintering, making the material distribution uniform and consistent, thereby improving the regularity of the processed products and ensuring the dimensional accuracy of the products. At the same time, the uniform powder state also helps to reduce the stress concentration caused by uneven material distribution during the sintering process, making the product surface smoother, more beautiful, and significantly improving the appearance quality and market competitiveness of the product.

[0024] 2. By adding and setting up a material conveying mechanism, during the process of ceramic powder conveying, this mechanism adopts a conveying method of mixing nitrogen with ceramic powder. Utilizing the inert gas characteristics of nitrogen, it effectively isolates the contact between the powder and oxygen and moisture in the air, avoids the performance deterioration of the powder caused by oxidation or moisture absorption during the conveying process, reduces the risk of dust explosion at the same time, and ensures production safety. At the same time, combined with variable-speed conveying technology, it avoids the impact and retention of ceramic powder at the start and end of conveying. This treatment method not only improves the material utilization rate but also reduces the cost of pipeline cleaning and maintenance. Moreover, the combined use of these two methods not only optimizes the conveying environment of ceramic powder but also fundamentally solves the potential problems of impact and retention, providing stable and pure material conditions for subsequent processing links.

[0025] 3. By adding and setting up a conveying and collecting mechanism, after the ceramic powder is conveyed, this mechanism separates and collects the ceramic powder mixed in nitrogen through a step-by-step separation method, thus achieving the effect of precisely capturing ceramic powder with different particle sizes mixed in nitrogen, greatly improving the powder recovery rate and purity. At the same time, by cooperating with the acoustic excitation method, it can effectively break the agglomeration phenomenon that may occur during the separation process, making the powder attached to the surface of the filter medium easier to fall off, further improving the separation efficiency and reducing the equipment operation load. The synergistic effect of this treatment method not only realizes the high-efficiency recycling and reuse of ceramic powder but also greatly reduces the nitrogen loss, significantly enhancing the environmental protection and economy of the production process.

[0026] 4. By adding and setting an electrostatic elimination mechanism, during the conveying process of ceramic powder, this mechanism processes the static electricity generated during the conveying process of ceramic powder through multiple electrostatic elimination methods. This processing method can not only effectively inhibit problems such as agglomeration and caking caused by static electricity adsorption of the powder and pipeline adhesion, thereby improving the use effect of ceramic powder during industrial manufacturing, but also effectively eliminate the static electricity accumulation of ceramic powder during the conveying process, reducing the safety risks in flammable and explosive environments from the root cause. At the same time, it also avoids the interference of static electricity on key indicators such as the mineral composition and particle size distribution of ceramic powder, which is beneficial to improving the yield of ceramic products.

Specific implementation manner

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to the attached Figure 1 - attached Figure 2 As shown in the figure, the embodiment of the present invention provides a material production and feeding device for industrial manufacturing, including a substrate 1, with a front-end box 4 and a rear-end box 14 respectively arranged on both sides of the top end. The front-end box 4 is used for feeding and dispersing ceramic powder, and the rear-end box 14 is used for collecting and processing after the ceramic powder is transported; the front-end box 4 and the rear-end box 14 are connected by a conveyor box 13, and the conveyor box 13 connects the interiors of the front-end box 4 and the rear-end box 14.

[0039] Please refer to the attached Figure 3 - attached Figure 5 As shown in the figure, a powder dispersion mechanism is arranged inside the front-end box 4 and is used for feeding and multiple dispersion processing of ceramic powder for industrial manufacturing.

[0040] The powder dispersion mechanism includes a trapezoidal cavity 18. A trapezoidal cavity 18 is opened in the upper middle part of the inner side of the front-end box 4. The middle part of the top end of the front-end box 4 is provided with a feed pipe 11, and the inside of the feed pipe 11 is communicated with the inside of the trapezoidal cavity 18. The middle part of the bottom end of the trapezoidal cavity 18 is rotatably connected with a feeding roller 19. A plurality of discharge chutes 20 are circumferentially arranged on the outer wall of the feeding roller 19. The middle upper part of one side of the front-end box 4 is provided with a driving motor 2 9, and the output end of the driving motor 2 9 penetrates through the front-end box 4 and is connected with the middle part of one end of the feeding roller 19.

[0041] When the powder dispersion mechanism is started, the ceramic powder is conveyed through the feeding equipment and enters the trapezoidal cavity 18 through the feeding pipe 11 on the front end box 4 for temporary storage and collection. Then, when the ceramic powder in the trapezoidal cavity 18 is collected and stored to a certain extent, the ceramic powder at the bottom of the trapezoidal cavity 18 enters the corresponding discharge grooves 20 respectively and fills them up. After that, the second driving motor 9 on the front end box 4 is started. While starting, the rotating shaft on the second driving motor 9 drives the blanking roller 19 at the bottom of the trapezoidal cavity 18 to rotate. While the blanking roller 19 is rotating, it drives the discharge grooves 20 filled with ceramic powder above it to rotate synchronously. Thus, while the discharge grooves 20 are rotating, the ceramic powder filled in them is transferred. After the ceramic powder in the discharge grooves 20 breaks away from the limit of the trapezoidal cavity 18, the ceramic powder in the discharge grooves 20 pours out and disperses from them.

[0042] The powder dispersion mechanism further includes a rotating seat 22. The two sides in the middle and lower part of the inner wall of the front end box 4 are both rotatably connected with the rotating seat 22. A plurality of obliquely arranged turning and scooping plates 23 are circumferentially arrayed between the two rotating seats 22. A first driving motor 7 is arranged at the middle and lower part on one side of the outer wall of the front end box 4, and the output end of the first driving motor 7 penetrates through the front end box 4 and is connected to the middle part of one end of the rotating seat 22.

[0043] Then the first driving motor 7 on the front end box 4 is started. While the rotating shaft of the first driving motor 7 is rotating, it drives the rotating seat 22 on it to rotate synchronously. While the rotating seat 22 is rotating, it drives the turning and scooping plates 23 on it to rotate synchronously. While the turning and scooping plates 23 are rotating, they disperse the agglomerated ceramic powder during the falling process, and simultaneously scoop up and turn over the ceramic powder falling on the bottom of the front end box 4, so as to disperse the ceramic powder again and facilitate the subsequent dispersion and conveying processes.

[0044] The material dispersion mechanism further includes a fixed frame 21. The middle and lower parts on both sides of the inner wall of the front end box 4 are both fixedly connected with the fixed frame 21. Rubber diaphragms 24 are arranged in the middle of the inner sides of the fixed frames 21. A plurality of sound wave transmission parts 25 are arranged on the rubber diaphragms 24 at equal intervals and staggered. Mounting seats 10 are fixedly connected to the middle and lower parts on the front and rear sides of the outer wall of the front end box 4. Sound wave generators 5 are arranged in the middle of the outer sides of the mounting seats 10. A plurality of diffusion channels 26 are equidistantly opened on one side of the mounting seats 10 close to the sound wave generators 5. Distribution cavities 27 are opened on the other side of the mounting seats 10 away from the sound wave generators 5. The diffusion channels 26 are respectively communicated with the interiors of the distribution cavities 27 on the same side.

[0045] Meanwhile, the acoustic wave generator 5 on the mounting base 10 is started. While starting, the acoustic wave generator 5 generates acoustic waves. The generated acoustic waves enter the diffusion flow channel 26 inside the mounting base 10 for diffusion and amplification. Then, the amplified acoustic waves are distributed onto the rubber diaphragm 24 on the fixed frame 21 through the distribution cavity 27 on the mounting base 10. The rubber diaphragm 24 excited by the acoustic waves synchronously vibrates the air in the space inside the front-end box 4 at the same time. And while being vibrated, the acoustic wave transmission part 25 generates laminar mixing of the ceramic powder distributed in the air inside the front-end box 4, and at the same time also breaks up the smaller agglomerated powder floating in the air, thereby completing the conveying and multiple dispersion treatment of the ceramic powder.

[0046] Please refer to the appendix Figure 6 - appendix Figure 7 , a powder conveying mechanism, which is arranged inside the conveying box 13 and is used for conveying the ceramic powder after being processed by the material dispersion mechanism;

[0047] The powder conveying mechanism includes a mounting box 6. The middle and lower part of one side of the front-end box 4 is fixedly connected with the mounting box 6. A drying cavity 33 is arranged inside the mounting box 6. A plurality of mounting rods 32 are fixedly connected at equal intervals inside the drying cavity 33. Heating wires 34 are arranged on the mounting rods 32. A nitrogen generator 8 is arranged in the middle of one side of the front-end box 4. The exhaust port of the nitrogen generator 8 is communicated with the inside of the drying cavity 33 through a connecting pipe. The drying cavity 33 is communicated with the inside of the front-end box 4 through an internal flow channel in the front-end box 4.

[0048] When the powder conveying mechanism is started, first, the nitrogen generator 8 on the front-end box 4 is started. While starting, the nitrogen generator 8 conveys the generated nitrogen into the mounting box 6 through the connecting pipe. After the nitrogen enters the drying cavity 33 inside the mounting box 6, the heating wires 34 on the mounting rods 32 are electrified to generate heat, heating and drying the nitrogen inside the drying cavity 33. Then, the heated and dried nitrogen enters the front-end box 4 and is mixed with the ceramic powder inside.

[0049] The powder conveying mechanism includes an axial flow fan 15. The middle and upper part of one side of the rear-end box 14 is provided with an axial flow fan 15. The axial flow fan 15 is used for pumping and discharging the gas inside the front-end box 4 and the conveying box 13. Sealing seats 16 are arranged at both ends of the conveying box 13. Two speed-changing plates 28 are fixedly connected at equal intervals at both ends inside the conveying box 13. A plurality of staggered slots 31 are arranged at equal intervals and staggeredly on the speed-changing plates 28.

[0050] Meanwhile, the axial flow fan 15 on the rear end box 14 starts. While starting, the axial flow fan 15 sucks the air inside the rear end box 14. While the air inside the rear end box 14 is flowing out, it guides the ceramic powder mixed with nitrogen in the front end box 4 to enter the rear end box 14 through the conveying box 13. When the ceramic powder mixed with nitrogen in the front end box 4 enters the inside of the conveying box 13, the ceramic powder mixed with nitrogen is limited in flow by the multiple offset slots 31 on the starting end variable speed plate 28 in the conveying box 13, thereby reducing the flow rate of the ceramic powder entering the conveying box 13. When the ceramic powder mixed with nitrogen flows to the middle of the conveying box 13, its high flow rate is restored again. Then, when the ceramic powder mixed with nitrogen in the conveying box 13 is conveyed to its terminal end, the ceramic powder in the flowing process is again limited in flow and decelerated by the offset slots 31 on the variable speed plate 28 in the terminal end of the conveying box 13, so as to complete the variable speed conveying process of the ceramic powder during the conveying process.

[0051] Please refer to the appendix Figure 8 , a conveying and collecting mechanism, which is arranged inside the rear end box 14 and is used for collecting the ceramic powder conveyed by the powder conveying mechanism;

[0052] The conveying and collecting mechanism includes a partition seat 38. The middle part of the inner side of the rear end box 14 is fixedly connected with a partition seat 38. The top of the partition seat 38 is fixedly connected with a plurality of mounting frames 36 at equal intervals. The middle parts of the inner sides of the mounting frames 36 are all provided with collecting screen plates 35. A plurality of V-shaped cavities 37 are equidistantly opened inside the partition seat 38.

[0053] When the conveying and collecting mechanism starts, when the ceramic powder after being conveyed by the powder conveying mechanism enters the rear end box 14, with the continuous entry of the ceramic powder mixed with nitrogen, the ceramic powder mixed with nitrogen sequentially passes through the collecting screen plates 35 on the mounting frames 36 at each position and is collected and intercepted by the collecting screen plates 35. At the same time, excited by the sound wave of the sound wave generator 5 on the front end box 4, the ceramic powder attached to the surfaces of the collecting screen plates 35 at each position vibrates and separates.

[0054] The conveying and collecting mechanism further includes a base 40. The bottom of the inner side of the rear end box 14 is provided with a base 40. A conical cavity 39 is opened in the middle of the top of the base 40. A material pumping pump 17 is arranged at the lower middle part of the rear side of the rear end box 14. The inlet of the material pumping pump 17 is communicated with the middle part of the bottom end of the conical cavity 39 through a connecting pipe.

[0055] Then, the ceramic powder separated by vibration from the collecting yarn board 35 and the powder separated and collected layer by layer fall through the V-shaped cavity 37 on the partition seat 38 into the conical cavity 39 in the base 40 for centralized collection. Then, when it is used for industrial processing, the feeding pump 17 on the rear end box 14 is started. The feeding pump 17 conveys and discharges the ceramic powder collected in the conical cavity 39 through the connecting pipe for use in industrial manufacturing and processing, thus completing the collection and re-conveyance treatment of the ceramic powder after conveyance.

[0056] Please refer to the attached Figure 1 - attached Figure 2 and attached Figure 9 , an electrostatic elimination mechanism, which is arranged on the conveying box 13 and is used to eliminate the static electricity generated during the conveying process of the ceramic powder.

[0057] The electrostatic elimination mechanism includes a carbon-based coating 29. The carbon-based coating 29 is arranged on the inner wall of the conveying box 13. A metal powder conductive coating 30 is covered on the outer wall of the conveying box 13. A conductive fiber mesh 41 is arranged inside the material of the conveying box 13, and the conductive fiber mesh 41 is respectively connected to the position of the metal powder conductive coating 30 at the corresponding position.

[0058] When the electrostatic elimination mechanism is started, when the powder conveying mechanism conveys the ceramic powder, the carbon-based coating 29 arranged on the inner wall of the conveying box 13 reduces the friction of the powder during the conveying and moving process. Then, the static electricity generated during the powder conveying process is conducted by the conductive fiber mesh 41 inside the conveying box 13 onto the metal powder conductive coating 30 on the surface of the conveying box 13.

[0059] The electrostatic elimination mechanism further includes a metal conductive layer 12. The metal conductive layer 12 is covered on the top of the substrate 1. A plurality of connecting buckle seats 3 are equidistantly arranged in the middle of the top end of the metal conductive layer 12. Metal grounding wires 2 are arranged inside the connecting buckle seats 3, and the top ends of the metal grounding wires 2 are respectively connected to the corresponding positions of the metal powder conductive coating 30.

[0060] Then, the static electricity conducted onto the metal powder conductive coating 30 is transmitted onto the metal conductive layer 12 on the substrate 1 through the cooperation of the metal grounding wire 2 at its bottom and the connecting buckle seat 3, and is finally conducted to the ground through the substrate 1, thus completing the elimination treatment of the static electricity during the powder conveying process.

[0061] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
