At this time, the first compression spring contracts. Due to the resilience of the first compression spring, multiple inserting blocks can be inserted into the mounting plate, thereby achieving the effect of quickly fixing and limiting the mounting plate. Thus, the effect of quickly splicing and fixing the first cylindrical cutting tool and the second cylindrical cutting tool can be achieved.

During continuous processing, the first cylindrical cutting tool and the second cylindrical cutting tool can be quickly separated through the quick disassembly structure, and the cutting tools can be more thoroughly treated with coolant. Therefore, it can effectively avoid processing interruption or quality decline caused by overheating of the cutting tools, thereby improving the overall processing efficiency. By the staff inserting the square block into the clamping seat, at this time, the staff rotates the screw rod to rotate inside the sliding groove. The rotation of the screw rod drives the moving block to slide inside the sliding groove. The movement of the moving block drives the movement of the rotating rod. The rotation of the rotating rod pushes the moving plate to slide inside the limiting box, and then multiple inserting rods are inserted into the square block, thereby achieving the effect of quickly fixing and limiting the square block. Thus, the effect of quickly installing and disassembling the first cylindrical cutting tool and the second cylindrical cutting tool can be achieved, facilitating subsequent inspection and maintenance of the first cylindrical cutting tool and the second cylindrical cutting tool by the staff.

[0016] 1. By inserting the mounting plate into the mounting groove, and then the staff pulls the adjusting rod to slide inside the fixed box. At this time, the adjusting rod drives the extrusion rod to slide inside the fixed tube. At this time, the first compression spring contracts. Due to the resilience of the first compression spring, multiple inserting blocks can be inserted into the mounting plate, thereby achieving the effect of quickly fixing and limiting the mounting plate. Thus, the effect of quickly splicing and fixing the first cylindrical cutting tool and the second cylindrical cutting tool can be achieved. Furthermore, the first cylindrical cutting tool and the second cylindrical cutting tool can be conveniently separated, increasing their contact area with air, thereby enhancing the heat dissipation effect. At the same time, it is also easier to clean the accumulated graphite fragments inside after disassembly, keeping the cooling channel unobstructed. During continuous processing, if the temperature of the cutting tool is too high, the first cylindrical cutting tool and the second cylindrical cutting tool can be quickly separated through the quick disassembly structure, and the cutting tools can be more thoroughly treated with coolant. Therefore, it can effectively avoid processing interruption or quality decline caused by overheating of the cutting tools, thereby improving the overall processing efficiency. Due to the tension generated by the second compression spring, the push plate can push the second cylindrical cutting tool to move, thereby assisting the movement of the second cylindrical cutting tool, greatly improving the disassembly efficiency of the second cylindrical cutting tool, and bringing practicality to the staff during use;

[0017] 2. The output shaft of the motor is fixedly connected to the square block by the staff, and then the square block is inserted into the clamping seat by the staff.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-5 , the present invention provides a technical solution: a circular cutting tool heat dissipation structure for graphite material extraction and separation, including a first cylindrical cutting tool 1 and a second cylindrical cutting tool 101, and the second cylindrical cutting tool 101 is arranged inside the first cylindrical cutting tool 1, and cutting teeth 102 are installed at one end of both the first cylindrical cutting tool 1 and the second cylindrical cutting tool 101, and an annular cooling plate 103 is installed inside the first cylindrical cutting tool 1 and the second cylindrical cutting tool 101; an adjusting mechanism 2 is arranged between the first cylindrical cutting tool 1 and the second cylindrical cutting tool 101, and a connecting component 3 is arranged at one end of the first cylindrical cutting tool 1;

[0026] Among them, the adjusting mechanism 2 includes a mounting plate 201 installed at one end of the second cylindrical cutting tool 101, and a mounting groove 202 is opened on one side inside the first cylindrical cutting tool 1, and the mounting plate 201 is inserted into the mounting groove 202, and fixing boxes 203 are symmetrically installed inside one end of the first cylindrical cutting tool 1, and an adjusting rod 204 is slidably connected inside the fixing box 203, and fixing tubes 205 are symmetrically installed on one side inside the fixing box 203, and a pressing rod 206 is slidably connected inside one end of the fixing tube 205, one end of the pressing rod 206 is fixedly connected to the outer retaining piece of the adjusting rod 204, and a first compression spring 207 is arranged inside the fixing tube 205, and a sliding plate 208 is installed at one end of the adjusting rod 204, and insertion blocks 209 are installed on one side of the sliding plate 208, and the insertion blocks 209 are inserted into the mounting plate 201, so as to achieve the effect of quickly splicing and fixing between the first cylindrical cutting tool 1 and the second cylindrical cutting tool 101, and further can conveniently separate the first cylindrical cutting tool 1 and the second cylindrical cutting tool 101, so that their contact area with the air is larger, thereby enhancing the heat dissipation effect. At the same time, it is also easier to clean the accumulated graphite fragments inside after disassembly, keeping the cooling channel unobstructed. During continuous processing, if the temperature of the cutting tool is too high, the first cylindrical cutting tool 1 and the second cylindrical cutting tool 101 can be quickly separated through the quick disassembly structure, and the cutting tool can be treated with coolant more thoroughly, thereby effectively avoiding processing interruption or quality decline caused by overheating of the cutting tool, and thus improving the overall processing efficiency;

[0027] A connecting tube 210 is installed inside the end of the first cylindrical cutter 1 close to the mounting plate 201, and a push rod 211 is slidably connected to the inside of the connecting tube 210. A groove 212 is provided on one side of the mounting plate 201, and a push plate 213 is installed at one end of the push rod 211. A second contraction spring 214 is provided inside the connecting tube 210. The tension generated by the second contraction spring 214 enables the push plate 213 to push the second cylindrical cutter 101 to move, thereby assisting the second cylindrical cutter 101 in moving, thereby greatly improving the efficiency of disassembling the second cylindrical cutter 101 and bringing practicality to the staff during use.

When the staff moves the sealing plate 217 on the rotating seat 216, the torsion spring 218 extends. When the staff completes the operation of the adjusting rod 204 through the cavity 215, the torsion spring 218 contracts rapidly, so that the sealing plate 217 and the cavity 215 can be buckled, thereby greatly reducing the phenomenon of graphite debris clogging the cavity 215, which brings convenience to the staff when using it.

[0029] The connecting component 3 includes a holder 301 installed at one end of the first cylindrical tool 1, and a block 302 is inserted into the inner side of the holder 301, and a limit box 303 is symmetrically installed on both sides of the holder 301, and a slide groove 304 is provided on the inner side of the limit box 303, and a screw 305 is rotatably connected to the inner side of the slide groove 304, and a moving block 306 is threadedly connected to the outer side of the screw 305, and a moving plate 307 is slidably connected to the inner side of the limit box 303, and a plug rod 308 is installed on one side of the moving plate 307, and the plug rod 308 is plugged into the block 302, and a rotating rod 309 is rotatably connected between the moving block 306 and the moving plate 307, and the moving plate 307 is rotatably connected to the inner side of the limit box 303. A retraction rod 310 is installed between them, and a third retraction spring 311 is sleeved on the outer side of the retraction rod 310, so that the effect of quickly fixing the limit block 302 can be achieved, and then the effect of quickly installing and removing the first cylindrical tool 1 and the second cylindrical tool 101 can be achieved, so that it is convenient for the staff to subsequently inspect and maintain the first cylindrical tool 1 and the second cylindrical tool 101, greatly improving the daily maintenance efficiency of the device, and bringing convenience to the staff when using it. The movement of the movable plate 307 drives the retraction rod 310 and the third retraction spring 311 to extend, and the contractility of the third retraction spring 311 can assist the movable plate 307 in subsequent resetting and movement, which brings practicality to the staff when using it.

[0030] Working principle: Before using this circular cutter heat dissipation structure for graphite separation, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, when the staff places the second cylindrical tool 101 inside the first cylindrical tool 1, the mounting plate 201 is inserted into the mounting groove 202, and then the staff pulls the adjusting rod 204 to slide inside the fixing box 203. At this time, the adjusting rod 204 drives the extruding rod 206 to slide inside the fixing tube 205. At this time, the first contraction spring 207 contracts, and by loosening the adjusting rod 204 and then through the reset of the first contraction spring 207, multiple groups of plug blocks 209 can be plugged into the mounting plate 201, thereby realizing fast fixed limit installation. The plate 201 has the effect of quickly splicing and fixing the first cylindrical tool 1 and the second cylindrical tool 101, and then the first cylindrical tool 1 and the second cylindrical tool 101 can be easily separated, so that their contact area with the air is larger, thereby enhancing the heat dissipation effect. At the same time, it is also easier to clean the graphite fragments accumulated inside after disassembly and keep the cooling channel unobstructed. During continuous processing, if the tool temperature is too high, the first cylindrical tool 1 and the second cylindrical tool 101 can be quickly separated through the quick disassembly structure to cool the tool more thoroughly. Cooling liquid treatment can effectively avoid processing interruption or quality degradation caused by tool overheating, thereby improving overall processing efficiency. When the mounting plate 201 is inserted into the inner side of the mounting groove 202, the push plate 213 is squeezed by the groove body 212 to drive the push rod 211 to move. At this time, the push rod 211 squeezes the second contraction spring 214 inside the connecting tube 210. When the first cylindrical tool 1 and the second cylindrical tool 101 are separated, the tension generated by the second contraction spring 214 can enable the push plate 213 to push the second cylindrical tool 101 to move, thereby It can assist the second cylindrical cutter 101 in moving, thereby greatly improving the efficiency of disassembling the second cylindrical cutter 101 and bringing practicality to the staff during use. When the staff turns the sealing plate 217 to rotate on the rotating seat 216, the torsion spring 218 is extended. When the staff completes the operation of the adjustment rod 204 through the cavity 215, the torsion spring 218 is quickly contracted, so that the sealing plate 217 and the cavity 215 are buckled, thereby greatly reducing the phenomenon of graphite debris blocking the cavity 215, bringing convenience to the staff during use.

[0031] The output shaft of the motor is fixedly connected to the square block 302 by the staff, and then the square block 302 is inserted into the inside of the card seat 301 by the staff. At this time, the staff rotates the screw rod 305 inside the chute 304. The rotation of the screw rod 305 drives the moving block 306 to slide inside the chute 304. The movement of the moving block 306 drives the movement of the rotating rod 309. The rotation of the rotating rod 309 pushes the moving plate 307 to slide inside the limiting box 303, so that a plurality of inserting rods 308 are inserted into the square block 302, thereby achieving the effect of quickly fixing and limiting the square block 302, and further achieving the effect of quickly installing and disassembling the first cylindrical cutter 1 and the second cylindrical cutter 101, so as to facilitate the staff to detect and maintain the first cylindrical cutter 1 and the second cylindrical cutter 101 subsequently, greatly improving the daily maintenance efficiency of the device, bringing convenience to the staff during use. The movement of the moving plate 307 drives the extension of the retractable rod 310 and the third compression spring 311. Through the contractility of the third compression spring 311, the subsequent reset movement of the moving plate 307 can be assisted, bringing practicality to the staff during use.

[0032] The first cylindrical cutter 1, the second cylindrical cutter 101, the cutter teeth 102 and the annular cooling plate 103 are prior arts. The device used is disclosed in the patent with publication number CN207593892U, a double-layer graphite cutting tool, and will not be elaborated here.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
