[0002] Isostatic graphite refers to a special type of graphite formed by isostatic pressing technology. It not only has great potential in civilian applications, but also occupies an important position in the cutting edge of national defense. It is a new type of material that has attracted much attention. It is also an irreplaceable material for manufacturing single crystal furnaces, graphite crystallizers for continuous casting of metals, and graphite electrodes for electrical discharge machining. Furthermore, it is an excellent material for manufacturing rocket nozzles, deceleration materials for graphite reactors, and reflective materials.

[0003] In the existing technology, the loading and unloading operations of graphite during calcination are cumbersome and mostly done manually or by hoisting equipment. Since the graphite green blanks are not calcined, they are prone to deformation or damage during this process. In addition, the current loading and unloading operations are time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0012] Optionally, a positioning mechanism is also included. The positioning mechanism is located in the factory and corresponds to the position of the material transfer mechanism. The base is cuboid in shape. The positioning mechanism includes a rectangular fence with an opening at one end. The ends of the fence on both sides of the opening are respectively connected to outwardly inclined guide rails. The two guide rails form a flared structure at the opening of the fence. The length of the fence is not less than that of the base. An elastic touch switch that cooperates with the material transfer mechanism is provided on the inner side wall of the fence. Multiple vertically rotating rollers are provided at equal intervals on the inner side walls of both sides of the fence and on the guide rails. The outer surface of the rollers is covered with a rubber layer. The spacing between the outer sides of the rollers on the inner side walls of both sides of the fence is adapted to the width of the base.

[0013] Optionally, the base is provided with four pulleys at the bottom, two of which are fixed as drive wheels and the other two are rotatable as steering wheels; The material rack is provided with a transmission assembly that is connected to two pulleys that serve as drive wheels.

[0015] The beneficial effects of this invention are: This invention can automatically load and unload batches of graphite, greatly improving the efficiency of loading and unloading operations. The graphite is clamped by a ring-shaped airbag that matches the shape of the graphite, so the outer wall of the graphite is subjected to uniform force and will not be deformed or damaged. Furthermore, different types of graphite can be clamped within a certain outer diameter range, making it highly versatile. The material rack is equipped with multi-layer support plates, which not only increases the amount of graphite loaded, but also enables automatic loading on the multi-layer support plates through the designed push plate assembly. After unloading, the unused support plates of the material rack automatically flip into the plate slot, reducing the volume of the support plates and reducing the possibility of the support plates being bumped in the factory. The graphite bottom is supported by several evenly arranged struts. The top of the struts is a spherical graphite pad to prevent damage to the bottom of the graphite blank or the entry of impurities. The support plates between the struts have pores, and the circumferential sidewalls of the support plates also have pores, so that the graphite bottom is subjected to uniform force and the bottom heat flows smoothly, making the graphite bottom heat evenly. The material rack can be pushed manually or driven by a quick-release drive box. Simply place the drive box on the material rack and rotate the lifting rod to quickly connect and disconnect the drive box. This not only makes operation simple but also improves transfer efficiency by driving the material rack with a motor. The material rack is less likely to go out of control, thus avoiding safety accidents. Operators can carry the drive box to quickly drive any material rack. The material rack itself does not carry fixed motors, batteries, or other electrical components, which not only avoids damage in the high-temperature environment of baking but also eliminates the need for maintenance of each material rack.

[0019] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0020] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-9 As shown, the present invention discloses an automated feeding system for isostatic graphite calcination, including a material rack 100 and two material transfer mechanisms 200. The material rack 100 contains graphite and sends the graphite into the calcination furnace for calcination. The material transfer mechanisms 200 load graphite into the material rack 100 or remove calcined graphite from the material rack 100.

[0023] The material rack 100 includes a horizontally arranged base 101, which is rectangular in shape and has four pulleys 106 at its bottom. A vertically arranged rectangular support 102 is provided on the base 101, and the support 102 is located on the center line of the base 101.

[0024] Multiple sets of support components are provided on both sides of the support 102, and the multiple sets of support components are equally spaced in the vertical direction. The support components serve as the structure for accommodating graphite.

[0025] The support assembly includes a slot 105 formed in the support 102, and a rectangular plate-shaped support plate 103 is hinged within the slot 105. One side of the support plate 103 is hinged to the inner bottom end of the slot 105. When the support plate 103 is rotated to a vertical position, it enters the slot 105, and at this time, the outer wall of the support plate 103 is flush with the side wall of the support 102. When the support plate 103 is rotated, it disengages from the slot 105 and rotates to a horizontal position. The bottom surface of the slot 105 contacts and limits the bottom surface of the support plate 103 at its top, keeping the support plate 103 horizontal and preventing it from swinging further downward.

[0026] A slot 107 is provided through the support plate 103, which makes the support plate 103 have a frame structure. When the support plate 103 is in a horizontal state, a number of through holes are evenly distributed on the side wall of the support plate 103 outside the slot 105, so that except for the side that is hinged to the slot 105, the other side walls of the support plate 103 are perforated plate structures.

[0027] The bottom of the slot 107 is provided with a horizontally arranged support plate 110. The edge of the support plate 110 is connected to the inner wall of the slot 107. Multiple vertical struts 108 are evenly distributed in a matrix on the support plate 110. The top of the strut 108 is provided with a spherical graphite pad 109. The height of the top of the strut 108 is lower than the top surface of the support plate 103, that is, the top of the side wall of the slot 107 is higher than the top of the strut 108.

[0028] A threaded rod is provided on the support plate 110 at the bottom of the support rod 108, and a threaded hole is provided coaxially at the bottom of the support rod 108 to engage with the threaded rod, so as to realize the detachable connection of the support rod 108 on the support plate 110. The area of ​​the support plate 110 where the support rod 108 is not provided has through holes, and the support plate 110 is also a perforated plate structure.

[0029] Two material transfer mechanisms 200 respectively transfer material to the support components on both sides of the support 102. Each material transfer mechanism 200 includes a material transfer seat 201, which is connected to a three-way moving device (not shown in the figure). The three-way moving device drives the material transfer seat 201 to move in three directions. The bottom of the material transfer seat 201 is provided with multiple material transfer components, which transfer graphite to the support plate 103 or transfer graphite from the support plate 103.

[0030] The material transfer assembly includes a cylindrical transfer cylinder 204, which is open at the bottom and closed at the top. A cylindrical air bladder 208 is provided on the inner wall of the transfer cylinder 204. The outer wall of the air bladder 208 is connected to the inner wall of the transfer cylinder 204. After the air bladder 208 is inflated, it is coaxial with the transfer cylinder 204. The inner wall of the air bladder 208 is made of rubber or other elastic material, so that the inner wall of the air bladder 208 can expand inward to reduce the inner diameter of the air bladder 208 when the internal air pressure of the air bladder 208 increases.

[0031] A connecting cylinder 203 is located at the center of the top of the transfer cylinder 204. The bottom of the connecting cylinder 203 is connected to the air bladder 208. Multiple pipes connected to the air bladder 208 are located within the transfer cylinder 204 at the bottom of the connecting cylinder 203. Multiple vertically arranged connecting pipes 202 are located at the bottom of the transfer seat 201. These connecting pipes 202 are arranged at equal intervals along a straight path, with the distance between adjacent connecting pipes 202 greater than the outer diameter of the transfer cylinder 204. The outer wall of the bottom end of the connecting pipe 202 has an external thread, and the inner wall of the top end of the connecting cylinder 203 has an internal thread that mates with the external thread of the connecting pipe 202. The connecting pipe 202 is threadedly connected to the connecting cylinder 203. An air pipe 207 is connected to the top end of the connecting pipe 202. The air pipe 207 is connected to an air source, which has the function of supplying gas to and extracting gas from the air pipe 207, ultimately achieving the purpose of adjusting the inflation degree of the air bladder 208.

[0032] A push plate assembly is also provided between the transfer seat 201 and the support plate 103. The push plate assembly cooperates with the transfer seat 201 to push the support plate 103 into the plate groove 105, or to push the support plate 103 out of the plate groove 105.

[0033] The push plate assembly includes two L-shaped slide rods 205. Each slide rod 205 includes a vertical part and a horizontal part that are perpendicularly connected to each other. The two slide rods 205 are slidably disposed on both sides of the transfer seat 201.

[0034] The top of the vertical section is slidably connected to the bottom of the transfer seat 201. The bottom of the transfer seat 201 is provided with a linear slide for driving the slide rod 205 to slide. The sliding trajectory of the slide rod 205 is perpendicular to the arrangement trajectory of the connecting pipe 202 and the rotation axis of the support plate 103. The horizontal section is arranged parallel to the sliding direction of the slide rod 205. The end of the horizontal section is connected to a horizontally arranged push rod 206, which is perpendicular to the horizontal section of the slide rod 205.

[0035] The bottom ends of the outer edges of the support plate 103 are respectively connected to two U-shaped forks 104, which are positioned corresponding to the two slide rods 205. The openings of the forks 104 face outwards, and the slot size of the forks 104 is larger than the outer diameter of the push rod 206.

[0036] When the support plate 103 is pushed into the slot 105, the transfer seat 201 moves, causing the push rod 206 to be at the same level as the slot of the fork 104. Then, the linear slide table drives the slide rod 205 to slide closer to the fork 104 until the push rod 206 on the slide rod 205 slides into the slot of the fork 104. Then the transfer seat 201 rises. At the same time, the slide rod 205 slides closer to the slot 105, so that the movement trajectory of the push rod 206 is an upward curve. This curve is an arc with the rotation axis of the support plate 103 as the center. The push rod 206 pushes the fork 104, causing the support plate 103 to flip up until it slides into the slot 105. At this time, the slot of the fork 104 is vertically upward. The transfer seat 201 rises, causing the push rod 206 to slide upward and disengage from the fork 104.

[0037] When the support plate 103 is pushed out of the slot 105 to a horizontal position, the transfer seat 201 drives the push rod 206 to be directly above the slot of the fork 104. Then, the transfer seat 201 descends, causing the push rod 206 to enter the fork 104. As the transfer seat 201 descends, the slide rod 205 slides away from the slot 105, making the movement trajectory of the push rod 206 a descending curve. Similarly, this curve is an arc with the rotation axis of the support plate 103 as the center. After the push rod 206 pushes the fork 104 and causes the support plate 103 to flip out to a horizontal position, the slot of the fork 104 is horizontally facing away from the slot 105. The slide rod 205 slides away from the slot 105, thus disengaging the slide rod 205 from the fork 104. The vertical part of the slide rod 205 has a certain length, that is, there is a certain distance between the push rod 206 and the transfer cylinder 204 in the vertical direction, so that the support plate 103 will not interfere with the transfer cylinder 204 during the process of the slide rod 205 and the push rod 206 pushing the support plate 103 to flip.

[0038] During the process of pushing the support plate 103 into the plate groove 105 or sliding the support plate 103 out of the plate groove 105, the transfer seat 201 only needs to be raised and lowered to adjust the rotational friction pair between the support plate 103 and the plate groove 105, so that the rotation of the support plate 103 has a certain resistance, thus avoiding the risk of the support plate 103 automatically falling out of the plate groove 105 after sliding into it.

[0039] The loading system also includes a positioning mechanism 300, which is located within the plant and corresponds to the position of the transfer mechanism 200. After the material rack 100 is positioned by the positioning mechanism 300, it also positions itself in relation to the transfer mechanism 200. The positioning mechanism 300 includes a fence 301, the height of which corresponds to the base 101. The fence 301 has a rectangular frame structure with an opening at one end. Guide rails 302 are connected to the ends of the fence 301 on both sides of the opening. The guide rails 302 are structurally matched to the fence 301, with their outer ends tilted outwards, forming a flared structure at the opening of the fence 301. The length of the fence 301 is not less than that of the base 101, and the width of the fence 301 is slightly greater than that of the base 101. Two elastic touch switches 304 are provided on the inner side wall of the fence 301. The transfer mechanism 200 can only operate when both elastic touch switches 304 are triggered simultaneously. Multiple vertically rotating rollers 303 are evenly spaced on the inner walls of both sides of the fence 301 and on the guide rail 302. The outer surface of each roller 303 is covered with a rubber layer. The spacing between the outer sides of the rollers 303 on the inner walls of both sides of the fence 301 is adapted to the width of the base 101.

[0040] When the material rack 100 is loading or unloading materials, it is pushed into the enclosure 301, causing the base 101 to contact the inner side wall of the enclosure 301. When both elastic touch switches 304 are triggered simultaneously, the material transfer mechanism 200 can load or unload materials. During the process of the material rack 100 entering the enclosure 301, the base 101 may have rolling contact with the roller 303, which guides the base 101.

[0041] The material rack 100 is also equipped with a drive mechanism, which can drive the material rack 100 to move automatically. The drive mechanism includes a transmission component 400, a steering component 500, and two drive components 600, which are detachably connected to the transmission component 400 and the steering component 500, respectively.

[0042] Two of the pulleys 106 at the bottom of the base 101 are drive wheels, which drive the material rack 100 to move. These two pulleys 106 are fixedly installed. The other two pulleys 106 are steering wheels, which allow the material rack 100 to turn during movement. These two pulleys 106 are rotatable.

[0043] The transmission assembly 400 is connected to two pulleys 106, which serve as drive wheels. The transmission assembly 400 includes a drive shaft 401 coaxially connected to the two pulleys 106, a worm gear 402 coaxially connected to the drive shaft 401, and a worm 403 that meshes with the worm gear 402 is vertically rotatably mounted on the base 101.

[0044] The steering assembly 500 is connected to two pulleys 106, which serve as steering wheels. The steering assembly 500 includes two L-shaped bent steering rods 501. Each steering rod 501 includes a short rod portion and a long rod portion connected together. The bent portion of the steering rod 501 is rotatably connected to the base 101. The end of the short rod portion of the steering rod 501 is connected to the pulley 106, and the end of the long rod portion of the steering rod 501 is hinged to a transmission rod 502. A T-shaped drive rod 503 is rotatably connected to the base 101 between the two steering rods 501. The drive rod 503 includes a crossbar portion, both ends of which are hinged to the ends of the transmission rods 502 on both sides. A longitudinal rod portion is vertically connected to the center of the crossbar portion, and a connecting rod 504 is vertically arranged and rotatably connected to the base 101 at the end of the longitudinal rod portion.

[0045] The drive assembly 600 includes a drive box 601, which contains an electrically connected motor, battery, and electronic control board. An upper connecting post is coaxially provided at the end of the motor shaft, and multiple vertically arranged plug rods 610 are provided at the bottom of the upper connecting post. A remote control is provided outside the drive box 601 and is connected to the electronic control board by wire or wireless means. The remote control can control the rotation of the motor.

[0046] A support ring 604 is provided on the bottom outer wall of the drive box 601. The support ring 604 has an arc-shaped groove coaxial with the motor shaft. A rubber layer is provided on the bottom of the support ring 604. A gate-shaped lifting rod 602 is provided in the groove. The lifting rod 602 includes a horizontally arranged first rod. The two ends of the first rod are respectively provided with vertically arranged second rods. The bottom ends of the two second rods pass through the groove and are located below the groove. The bottom ends of the two second rods are provided with spherical locking blocks 605. The outer diameter of the locking blocks 605 is larger than that of the second rods. The second rod part above the groove is provided with a pressure block 606 that cooperates with the support ring 604. The pressure block 606 also cannot pass through the groove. A handle 603 is provided on the top of the first rod.

[0047] The drive assembly 600 also includes a lower connecting post rotatably mounted on the top surface of the base 101 and coaxially connected to the connecting rod 504 and the worm gear 403 respectively. The lower connecting post is provided with a plurality of insertion holes that mate with the insertion rod 610. The base 101 on the outer side of the lower connecting post is provided with two arc-shaped grooves 608 with the arrangement trajectory corresponding to the rod groove. The two grooves 608 are located radially on the same lower connecting post and are symmetrical. The width of the grooves 608 is adapted to the ball diameter of the locking block 605. The slot 608 is provided with a locking plate 609 that gradually descends from one end to the other. The locking plate 609 has a slot through which the second rod can slide. The high end of the locking plate 609 matches the length of the second rod below the pressure block 606. When the locking block 605 is at the high end of the locking plate 609, the pressure block 606 contacts the support ring 604. At this time, the lifting rod 602 is rotated by the handle 603. The lifting rod 602 drives the two locking blocks 605 to be locked into the bottom of the two locking plates 609 respectively. As the bottom surface of the locking plate 609 gradually decreases, the locking blocks 605 gradually pull the second rod downward, so that the pressure block 606 gradually presses the support ring 604 onto the base 101, thereby fixing the drive box 601.

[0048] When the unloaded material rack 100 has its support plate 103 in the plate groove 105, the material rack 100 is placed in the positioning mechanism 300 for positioning, and then the two material transfer mechanisms 200 load materials onto both sides of the support 102 respectively. A platform is provided on the side of the positioning mechanism 300. Graphite billets are placed according to the positional relationship of the transfer cylinder 204 at the bottom of the transfer seat 201. The transfer seat 201 moves above the graphite billets. After the transfer cylinder 204 aligns with the positions of multiple graphite billets, the transfer seat 201 descends. At this time, the air bladder 208 is not inflated. The inner diameter of the transfer cylinder 204 is larger than the outer diameter of the graphite billet. After the transfer cylinder 204 covers the outside of the graphite billet, the air bladder 208 inflates, causing the inner wall of the air bladder 208 to contact the outer wall of the graphite billet and clamp it. Then, the transfer seat 201 moves multiple graphite billets to the side of the corresponding support 102. During loading, it starts from the bottom support plate 103. The transfer seat 201 first descends to above the bottom support plate 103, so that... Push rod 206 enters the fork 104 of the support plate 103. Then, transfer seat 201 continues to descend and slide rod 205 slides away from plate groove 105, so that push rod 206 cooperates with fork 104 to flip support plate 103 outward until it is horizontal. Then slide rod 205 slides to make push rod 206 disengage from fork 104. Transfer seat 201 descends so that transfer cylinder 204 is on support plate 103. At this time, graphite green blank is on support plate 103. Then airbag 208 exhausts and shrinks, no longer clamping graphite green blank. Graphite green blank falls onto support plate 103, completing the single loading of multiple graphite green blanks on support plate 103. Then transfer seat 201 repeats the above process to load multiple support plates 103 sequentially from bottom to top. After loading is completed, material rack 100 is pushed into calcining furnace for calcination.

[0049] After the graphite is calcined, during unloading, the material rack 100 is placed on the positioning mechanism 300 for positioning, and then the two material transfer mechanisms 200 unload the graphite from both sides of the support 102. A platform or conveyor belt is set on the side of the positioning mechanism 300 to unload the calcined graphite onto the platform or conveyor belt. During unloading, the uppermost support plate 103 performs the unloading, and then the unloading proceeds downwards. The material transfer seat 201 moves multiple material transfer cylinders 204 above multiple graphite pieces. Since the position of the graphite has not changed after calcination, the position of the graphite on the support plate 103 still corresponds to the multiple material transfer cylinders 204. The material transfer seat 201 descends onto the support plate 103 so that the material transfer cylinders 204 cover the multiple graphite pieces. Then, the air bladder 208 inflates to clamp the graphite. Since the volume of graphite will slightly shrink after calcination, the amount of air in the air bladder 208 increases. After the material transfer cylinders 204 clamp the graphite, the material transfer seat 201 moves to push the graphite. The rod 206 is positioned corresponding to the fork 104. Then, the slide rod 205 slides to allow the push rod 206 to enter the fork 104, and the transfer seat 201 rises. During this process, the slide rod 205 slides to drive the push rod 206 to push the fork 104 until the support plate 103 slides into the plate groove 105. Then, the transfer seat 201 continues to rise, causing the push rod 206 to disengage from the fork 104 through the opening at the top of the fork 104. The above process is repeated until the unloading of multiple support plates 103 is gradually completed from top to bottom. After unloading, the support plates 103 are all flipped into the plate groove 105, and the material rack 100 waits for the next loading.

[0050] During movement, the material rack 100 can be manually pushed or driven by placing the drive box 601 on the material rack 100. Since the drive box 601 and the material rack 100 are connected by a quick-release mechanism, when connecting, the insertion rod 610 of the upper connecting post at the bottom of the drive box 601 is inserted into the corresponding insertion hole of the lower connecting post. Then, by rotating the lifting rod 602 and engaging the locking block 605 with the locking plate 609 in the locking slot 608, the drive box 601 is pressed firmly onto the base 101 of the material rack 100, quickly placing the drive assembly 600 on the material rack 100. The material rack 100 can then be driven to move and turn by a remote control. Correspondingly, after the material rack 100 enters the roasting furnace, the lifting rod 602 is rotated to disengage the clamping block 605 from the clamping plate 609, and the drive box 601 can be pulled out. This avoids damage to electrical components such as motors and batteries entering the roasting furnace. In addition, the operator is equipped with a set of two hand-held drive boxes 601, which can quickly drive any material rack 100.

[0051] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the technical solutions of the present invention. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of the patent of the present invention.
