Description

Technical Field

[0001] This invention relates to the field of graphite powder production and feeding technology, and in particular to an automated feeding system for graphite powder sintering. Background Technology

[0002] Graphite powder sintering is a powder metallurgy process that transforms loose graphite powder into a dense solid through high temperature and high pressure. Sintered graphite materials prepared by this method possess properties such as high temperature resistance, excellent electrical and thermal conductivity, chemical stability, and self-lubrication. Therefore, it is widely used in key areas of the metallurgical industry, such as electric arc furnace electrodes, thermal field systems of semiconductor single crystal silicon pulling furnaces, fuel cell bipolar plates, mechanical seals, and nuclear reactor moderators. It is a core technology for the preparation of high-performance graphite products in modern industry. In the sintering process of graphite powder, to improve the automation and convenience of sintering, a feeding system for graphite powder sintering is generally provided. For example, existing publications CN108161015B – a crushing device for an automatic feeding device in metal powder metallurgy and CN222076374U – a feeding system for a powder sintering kiln – both disclose an automatic feeding device (system) for powder. While these feeding devices can achieve feeding during powder processing, they still have the following shortcomings when used for feeding graphite powder in sintering: 1. During the stirring process before sintering graphite powder, in order to improve the properties of graphite powder, additives such as liquid binders and modifying additives are added in a certain proportion. These additives include both solids and liquids. If a single feeding system is used for feeding, a certain amount of material will adhere to the inside of the feeding system during long-term use, resulting in a large error in the mixing ratio and making it difficult to clean the inside of the system. 2. In order to maintain the excellent performance of graphite powder after sintering, each raw material needs to be weighed before it can be added. The existing feeding system requires the staff to manually weigh each raw material first, which is complicated and indirectly increases the labor intensity of the staff. Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] In view of the problems that existing automatic feeding systems are not conducive to the mixing of various raw materials and increase the cleaning intensity of workers, an automated feeding system for graphite powder sintering is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automated feeding system for graphite powder sintering, comprising a feeding mechanism including a weighing and conveying component and a transfer component, wherein multiple feeding mechanisms are arranged vertically, and the transfer component includes an outer protective cylinder, a transfer plate, a first toothed disc, a second toothed disc, and a third toothed disc. A semi-circular bottom plate is fixedly provided at the lower end of the inner side of the outer protective cylinder near the weighing and conveying component, and a semi-circular extension plate is coaxially fixedly provided at the center of the diameter surface of the semi-circular bottom plate. A transfer plate is provided in the outer protective cylinder above the semi-circular bottom plate, and a rotating disc is embedded and fixedly provided at the center of the bottom surface of the transfer plate. A placement groove is opened inside the connecting body of the semi-circular bottom plate and the semi-circular extension plate, and both the first toothed disc and the second toothed disc are placed in the placement groove. A rotating disc is fixedly provided on the top surface of the first toothed disc. The device includes a drive disc, which is coaxially arranged and fixed to the rotating disc by bolts. A first toothed disc and a second toothed disc are meshed together, and a third toothed disc located outside the outer casing meshes with the second toothed disc. It also includes an assembly mechanism comprising multiple end-sealing plates arranged in an array along a vertical direction and a support rod for connecting adjacent end-sealing plates, with the support rod located outside the outer casing. Two adjacent feeding mechanisms are symmetrically arranged with partial overlap on the same horizontal plane, and the overlapping areas of the outer casings form a top-to-bottom conveying channel. Two adjacent semi-circular bottom plates are completely staggered. End-sealing plates are located at both ends of the outer casing, and adjacent outer casings share a single end-sealing plate. A material passage groove aligned with the conveying channel is provided on the end-sealing plate between adjacent outer casings.

[0006] The beneficial effects of this invention are as follows: When this feeding system is in use, the raw materials conveyed by the weighing and conveying components are transferred to the outer protective cylinder above the semi-circular bottom plate. Through the rotation of the third toothed disc, and under the transmission of the second toothed disc, the first toothed disc can drive the drive disc to rotate, and finally the rotating disc drives the material transfer plate to rotate, pushing the raw materials in the outer protective cylinder into the feeding channel for feeding. By setting multiple material transfer components, different raw materials can be transferred to different outer protective cylinders separately. The feeding channel composed of multiple material transfer components can facilitate the feeding of various raw materials through the feeding channel. The feeding channel is set vertically, which avoids the mixing of various raw materials in the outer protective cylinder and the resulting adhesion of raw materials. This ensures that the addition ratio error is small and also reduces the frequency of cleaning by the staff.

[0007] As a preferred embodiment of the automated feeding system for graphite powder sintering of the present invention, wherein: a rotating column is fixedly sleeved in the middle of the second toothed disc, and the end of the rotating column is rotatably connected to the inner wall of the placement groove; an output shaft is fixedly provided in the middle of the top surface of the third toothed disc, the upper end of the output shaft is fitted into the output end of the second motor, and the second motor is fixedly connected to the outer wall of the outer casing.

[0008] As a preferred embodiment of the automated feeding system for graphite powder sintering of the present invention, a sealing ring is fixedly provided circumferentially on the side wall of the drive disk, and a sealing groove for clearance fit of the sealing ring is provided on the semi-circular bottom plate, and a rubber ring is sleeved on the outer side of the sealing ring; a rectangular column is fixedly provided in the middle of the top surface of the drive disk, and a rectangular groove for sliding insertion of the rectangular column is provided on the bottom surface of the rotating disk.

[0009] As a preferred embodiment of the automated feeding system for graphite powder sintering of the present invention, wherein: scrapers that fit against the inner wall of the outer casing are fixed on both sides of the transfer plate in the vertical direction, and the horizontal cross section of the connection between the transfer plate and the scraper is Z-shaped.

[0010] As a preferred embodiment of the automated feeding system for graphite powder sintering of the present invention, a second flange ring is fixedly provided on the outer side wall of both the upper and lower ends of the outer casing, and the second flange ring and the mounting hole opened on the end sealing plate are fixedly connected by bolts.

[0011] As a preferred embodiment of the automated feeding system for graphite powder sintering of the present invention, a discharge hood aligned with the material conveying channel is fixed on the bottom surface of the lowest end sealing plate, and connecting angle steels are symmetrically fixed on one side of both the upper and lower end end sealing plates.

[0012] Given the high labor intensity caused by the need for manual weighing by workers in existing feeding systems, an automated feeding system for graphite powder sintering is further optimized and improved in this invention. The weighing and conveying assembly includes an outer protective box and a conveyor belt, with the conveyor belt positioned inside the outer protective box. One end of the outer protective box is fixed to the outer wall of the upper end of the outer protective cylinder. Rollers are slidably sleeved inside both ends of the conveyor belt, and rotating rods are fixedly sleeved within the rollers. Both ends of the rotating rods are rotatably connected to the outer wall of the outer protective box via rolling bearings. One end of one of the rotating rods extends to the outside of the outer protective box and is embedded in the output end of a first motor, which is fixedly connected to the outer wall of the outer protective box. Multiple partitions are arrayed and fixedly installed on the outer wall of the conveyor belt along the conveying direction. A feed cylinder is fixedly installed on the top surface of the outer protective box on the side away from the outer protective cylinder, and a first flange ring is fixedly installed on the upper outer wall of the feed cylinder.

[0013] Another beneficial effect of the present invention is that when the feeding system is in use, the raw material is added through the feeding cylinder and falls onto the conveyor belt. During the conveying process of the conveyor belt, the partitions will flatten the raw material and place it equally on the conveyor belt between the partitions. In this way, the weight of the raw material between each partition is equal. As the conveyor belt is conveyed, the raw material can be automatically weighed according to the number of partitions that move, which effectively reduces the labor intensity of the workers and the overall operation is convenient and effective.

[0014] As a preferred embodiment of the automated feeding system for graphite powder sintering of the present invention, wherein: concealment grooves for the clearance fit of the conveyor belt are provided on both inner walls of the outer protective box, and a guide slope is fixed on the inner bottom surface of the outer protective box at the end of the conveyor belt near the outer protective cylinder.

[0015] As a preferred embodiment of the automated feeding system for graphite powder sintering of the present invention, a slot for sliding engagement of an adjusting plate is provided on the top plate of the outer protective box between the feeding cylinder and the outer protective cylinder along the width direction of the conveyor belt. An extension ear is fixed at the upper end of one side surface of the adjusting plate, a screw post is spirally sleeved in the extension ear, and a limiting plate is fixed at the lower end of the screw post. A positioning head for clearance fit of the lower end of the screw post is fixed on the top surface of the outer protective box. Attached Figure Description

When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example 1

[0028] Reference Figure 1 , Figure 5 and Figure 7 This is the first embodiment of the present invention. This embodiment provides an automated feeding system for graphite powder sintering. When the automated feeding system is in use, the weighing and conveying component 101 is used for conveying and weighing the raw materials, the material transfer component 102 is used for transferring the weighed raw materials out, and the assembly mechanism 200 is used for the cooperative connection between the various feeding mechanisms 100.

[0029] Specifically, it includes a feeding mechanism 100, which includes a weighing and conveying assembly 101 and a transfer assembly 102. Multiple feeding mechanisms 100 are arranged vertically. The transfer assembly 102 includes an outer protective cylinder 102a, a transfer plate 102b, a first toothed disc 102c, a second toothed disc 102d, and a third toothed disc 102e. It also includes an assembly mechanism 200, which includes multiple end sealing plates 201 arranged in an array along the vertical direction and a support rod 202 for connecting two adjacent end sealing plates 201. The support rod 202 is located outside the outer protective cylinder 102a.

[0030] See details Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a semi-circular bottom plate 102a-3 is fixedly installed at the lower end of the inner side of the outer casing 102a near the weighing and conveying assembly. A semi-circular extension plate 102a-4 is coaxially fixed at the center of the diameter surface of the semi-circular bottom plate 102a-3. A transfer plate 102b is provided in the outer casing 102a above the semi-circular bottom plate 102a-3. A rotating disk 102b-1 is fitted and fixed at the center of the bottom surface of the transfer plate 102b. A placement groove 102a-2 is opened inside the connecting body of the semi-circular bottom plate 102a-3 and the semi-circular extension plate 102a-4. The first toothed disk 102c and the second toothed disk 102d are both placed in the placement groove 102a-2. A drive disk 102c-1 is fixedly installed on the top surface of the first toothed disk 102c. The drive disk 102c-1 and the rotating disk 102b are coaxially arranged. -1 are fixed by bolts to facilitate detachable connection between drive disk 102c-1 and rotating disk 102b-1. The first gear disk 102c and the second gear disk 102d are meshed. The third gear disk 102e located outside the outer casing 102a meshes with the second gear disk 102d. A rotating column 102d-1 is fixedly sleeved in the middle of the second gear disk 102d. The end of the rotating column 102d-1 is rotatably connected to the inner wall of the placement groove 102a-2 to realize the free rotation of the second gear disk 102d. An output shaft 102e-1 is fixedly provided in the middle of the top surface of the third gear disk 102e. The upper end of the output shaft 102e-1 is embedded in the output end of the second motor 102e-2. The second motor 102e-2 is fixedly connected to the outer wall of the outer casing 102a. In use, the above configuration allows the output shaft 102e-1 to drive the rotation of the third gear disk 102e via the operation of the second motor 102e-2. The second gear disk 102d meshes with the first gear disk 102c and the third gear disk 102e respectively, ultimately enabling the drive disk 102c-1 to drive the rotating disk 102b-1 to rotate, so that the transfer plate 102b can transfer the raw material above the semi-circular bottom plate 102a-3 to the material conveying channel on the other side of the semi-circular bottom plate 102a-3.

[0031] Furthermore, a sealing ring 102c-2 is fixed circumferentially on the side wall of the drive disk 102c-1, and a sealing groove 102a-5 for clearance fit of the sealing ring 102c-2 is opened on the semi-circular bottom plate 102a-3 to improve the sealing performance of the drive disk 102c-1 and the semi-circular bottom plate 102a-3. A rubber ring 102c-3 is sleeved on the outer side of the sealing ring 102c-2 to increase the sealing performance. A rectangular column 102c-4 is fixed in the middle of the top surface of the drive disk 102c-1, and a rectangular groove 102b-2 for sliding insertion of the rectangular column 102c-4 is opened on the bottom surface of the rotating disk 102b-1 to enable the drive disk 102c-1 to drive the rotating disk 102b-1 to rotate more stably.

[0032] Furthermore, scraper strips 102b-3 that fit against the inner wall of the outer casing 102a are fixed vertically on both sides of the transfer plate 102b. The horizontal cross-section of the connecting body of the transfer plate 102b and the scraper strips 102b-3 is Z-shaped, so that the raw material attached to the side wall of the outer casing 102a can be scraped off.

[0033] See details Figure 7 and Figure 8 As shown, two adjacent feeding mechanisms 100 are symmetrically arranged with partial overlap on the same horizontal plane, and the overlapping areas of the outer protective cylinders 102a form a conveying channel from top to bottom. Two adjacent semi-circular bottom plates 102a-3 are completely staggered. End sealing plates 201 are set at both ends of the outer protective cylinders 102a, and adjacent outer protective cylinders 102a share a common end sealing plate 201. The end sealing plates 201 between adjacent outer protective cylinders 102a have material passage grooves 201c aligned with the conveying channel. The material passage grooves 201c are used for material discharge. In this way, the raw materials temporarily stored in the outer protective cylinders 102a can be transferred out through the conveying channel under the rotation of the transfer plate 102b.

[0034] Furthermore, a second flange ring 102a-1 is fixed on the outer side wall of both the upper and lower ends of the outer casing 102a, and the second flange ring 102a-1 and the mounting hole 201d opened on the end sealing plate 201 are fixedly connected by bolts. A discharge hood 201b aligned with the material conveying channel is fixed on the bottom surface of the lowermost end sealing plate 201. The discharge hood 201b is used for the discharge of raw materials, and connecting angle steels 201a are symmetrically fixed on one side of both the upper and lower end end sealing plates 201 to facilitate the fixed installation of the feeding system.

[0035] In addition, the present invention also includes a controller (not shown in the figures) for controlling various electrical components, the controller being positioned in a location convenient for operators to use. Example 2

[0036] Reference Figure 2 , Figure 4 , Figure 5 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that, in order to facilitate the automated weighing of each raw material, so as to improve the ease of operation and reduce the labor intensity of the workers, the specific structure of the weighing and conveying component 101 is described in detail.

[0037] Specifically, the weighing and conveying assembly 101 includes an outer protective box 101a and a conveyor belt 101b, with the conveyor belt 101b disposed inside the outer protective box 101a. One end of the outer protective box 101a is fixed to the outer wall of the upper end of the outer protective cylinder 102a. Rollers 101b-2 are slidably sleeved inside both ends of the conveyor belt 101b. A rotating rod 101b-3 is fixedly sleeved in the roller 101b-2, and both ends of the rotating rod 101b-3 are rotatably connected to the outer wall of the outer protective box 101a through rolling bearings. One end of one of the rotating rods 101b-3 extends to the outside of the outer protective box 101a and is embedded in a first electric... In the output end of the machine 101b-4, the first motor 101b-4 is fixedly connected to the outer wall of the outer protective box 101a. Multiple partitions 101b-1 are fixedly arranged in an array along the conveying direction on the outer wall of the conveyor belt 101b. The partitions 101b-1 can divide the outer protective box 101a above the conveyor belt 101b into independent spaces. A feed cylinder 101a-1 is fixedly arranged on the top surface of the outer protective box 101a away from the outer protective cylinder 102a. A first flange ring 101a-2 is fixedly arranged on the upper outer wall of the feed cylinder 101a-1 to facilitate the connection between the feed cylinder 101a-1 and the conveying structure. In use, the above-mentioned setup drives the roller 101b-2 to rotate through the operation of the first motor 101b-4, thereby realizing the movement and conveying of the conveyor belt 101b. During the movement of the conveyor belt 101b, the raw material falls from the feed cylinder 101a-1 onto the conveyor belt 101b. The partitions 101b-1 on the conveyor belt 101b divide and transfer the raw material equally. In actual use, the counting module counts the number of times the partitions 101b-1 move to a certain position, and finally, the weight of the raw material on the conveyor belt 101b can be automatically weighed after conversion.

[0038] Furthermore, concealing grooves 101a-6 are provided on both inner walls of the outer protective box 101a for clearance fit with the conveyor belt 101b. This improves the sealing between the conveyor belt 101b and the outer protective box 101a, facilitating better weighing and transfer of liquid materials. A guide slope 101a-3 is fixed on the bottom inner surface of the outer protective box 101a near the end of the conveyor belt 101b close to the outer protective cylinder 102a, so as to better transfer materials from the outer protective box 101a to the outer protective cylinder 102a. Example 3

[0039] Reference Figure 2 , Figure 4 and Figure 5 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that in order to realize the automatic adjustment of the transfer weight of single-quantity materials between the partitions 101b-1, and thus realize more effective and diverse weighing of different materials, this embodiment is proposed.

[0040] Specifically, a slot 101a-4 for sliding engagement of an adjusting plate 101c is provided on the top plate of the outer protective box 101a, located between the feed cylinder 101a-1 and the outer protective cylinder 102a, along the width direction of the conveyor belt 101b. An extension ear 101c-1 is fixed at the upper end of one side of the adjusting plate 101c. A screw post 101c-2 is spirally sleeved in the extension ear 101c-1, and a limiting plate 101c-3 is fixed at the lower end of the screw post 101c-2. A positioning head 101a-5 for clearance fit at the lower end of the screw post 101c-2 is fixed on the top surface of the outer protective box 101a, so as to realize the free rotation of the screw post 101c-2. In use, the above-mentioned configuration allows the extension ear 101c-1 to move the adjustment plate 101c in the vertical direction by rotating the screw post 101c-2. This allows the height position of the adjustment plate 101c inside the outer protective box 101a to be adjusted, and the distance between the adjustment plate 101c and the partition 101b-1 can be adjusted. Overall, it has good practicality.

[0041] Additionally, it should be noted that components not described in detail in this article are existing technologies.
