[0024] The reset member comprises the four fixed cylinders fixedly connected to the bottom of the forming table, and the support table is fixedly connected with the four spring reset rods;

[0025] When the high-pressure gas in the plurality of gas outlet grooves is sprayed, the gas sprayed in a single gas outlet groove separates the partial area of the graphite block from the mold, and the plugging assembly plugs the gas outlet groove, so that the gas is concentrated and sprayed from other gas outlet grooves, effectively preventing the adhesion force of the graphite block and the inner wall of the forming hole in each area from being different, and the area with weak adhesion force is separated, so that the gas in the annular groove is concentrated and sprayed from the position, resulting in gas dissipation.

[0026] Preferably, the support assembly comprises a sliding table slidingly connected to the outer wall of the four fixed rods, and the bottom of the sliding table is fixedly connected with an extrusion rod, and the bottom output end of the hydraulic cylinder is fixedly connected with the top of the sliding table.

[0035] When the gas is extruded by the extrusion ring, the gas first enters the inclined surface flow guide ring and flows through the gap between the inclined surface flow guide ring and the inclined surface ring, so that the inclined surface ring is in a high-pressure environment, at this time, the inclined surface ring is in a static state, when the high-pressure gas is sprayed from the gas outlet groove to the graphite block, the graphite block separates from the inner wall of the forming hole around the gas outlet groove, and then the gas sprayed from the gas outlet groove escapes outward, at this time, the gas flow rate in the gas outlet groove is accelerated, when the gas flows along the gap between the inclined surface flow guide ring and the inclined surface ring, a strong suction force is generated on the inclined surface ring, the inclined surface ring is attracted to move, the inclined surface ring contacts the inclined surface of the inclined surface flow guide ring, the gas outlet groove is blocked, and the gas is concentrated to be sprayed from the remaining gas outlet groove.

[0038] The application has the following beneficial effects:

[0039] (1) When the present application is used, the user adds graphite powder into the forming hole, and through the support assembly and the forming assembly, the graphite powder is pressed into a graphite block, then the electric telescopic rod is started to extend, the connecting rod and the extrusion ring are pushed to rise, the gas in the extrusion ring groove is extruded, the gas pressure is increased, at the same time, when the extrusion ring rises, the fixed frame is also lifted, the jetting assembly is pushed to move, the left side of the gas blocking rod is separated from the gas outlet groove, at this time, the high-pressure gas in the ring groove is sprayed around the graphite block, the adhesion between the graphite block and the forming hole is reduced, the graphite block and the inner wall of the forming hole are separated, thereby reducing the pushing force when the graphite block is demolded, effectively preventing the graphite block from being demolded, the excessive pushing force causes the graphite block to appear micro-cracks, avoiding the high temperature generated by graphitization from causing the cracks to increase, and ensuring the integrity of the graphite block during graphitization.

[0040] (2) When the present application extrudes the gas, the gas enters the inclined flow guide ring, flows through the gap between the inclined flow guide ring and the inclined ring, and when the graphite block and the inner wall of the forming hole around the single gas outlet groove are separated, the gas will escape outward, at this time, the gas flow rate in the gas outlet groove is accelerated, the gas outlet groove is blocked through the blocking assembly, so that the gas is concentrated and sprayed from the remaining gas outlet groove, effectively preventing the adhesion between the graphite block and the inner wall of the forming hole in different areas, the area with weak adhesion will be separated from the inner wall of the forming hole first, so that the gas in the ring groove is concentrated and sprayed from the position, causing the gas to escape, affecting the pushing force of the gas, and causing the remaining area of the graphite block to be difficult to separate from the forming hole.

[0041] (3) When the high-pressure gas in the extrusion ring is sprayed, the electric telescopic rod is retracted, the connecting rod and the extrusion ring are lowered, the extrusion ring is reset, at this time, the electric telescopic rod is continuously retracted, the extrusion ring drives the forming table to descend, the concave-convex rod is lowered, the hinged plate is pushed to rotate, the spring support rod is pushed to rise, and the graphite block is lifted, when the concave-convex rod and the hinged plate are separated, the spring support rod releases the elastic force and resets itself, since the graphite block slides in the forming hole, the forming hole limits the descending speed of the graphite block, the contact surface of the two is slightly pulled, through multiple lifting, the bottom of the graphite block and the top of the spring support rod are slowly separated, effectively preventing the graphite block from being taken, the adhesion between the bottom of the graphite block and the top of the spring support rod is strong, a larger pulling force appears between the two, and the particles at the bottom of the graphite block fall off.

[0042] (4) When the gas blocking rod moves towards the fixed frame, the spring inclined plate contacts the inclined ring, the inclined ring is pushed to move, until the inclined ring contacts the blocking ring, the spring inclined plate pushes the inclined ring to move, so that the inclined ring and the inclined flow guide ring are in a separated state, effectively preventing the high-pressure gas in the ring groove from pushing the inclined ring and the inclined flow guide ring to closely contact after the inclined ring and the inclined flow guide ring are in contact, affecting the flow of the gas in the next time, and affecting the gas to separate the graphite block.

[0077] In example two, please refer to Figures 1-8 The present application is a kind of lithium battery negative material processing equipment, based on example one, support assembly 11 includes sliding table 114 slidingly connected to the outer wall of four fixed rods one 112, the bottom of sliding table 114 is fixedly connected with extrusion rod 115, the bottom output end of hydraulic cylinder 113 is fixedly connected with the top of sliding table 114.

[0078] Forming assembly 12 includes forming hole 122 opened in the inner wall of forming table 121, support table 111 is fixedly connected with blocking rod 123, spring support rod 124 is slidingly connected to the inner wall of blocking rod 123;

[0079] The outer wall of blocking rod 123 is slidingly connected with the inner wall of forming hole 122, and the outer wall of extrusion rod 115 is slidingly connected with the inner wall of forming hole 122;

[0080] Among them, the operator adds graphite powder into the forming hole 122, so that the graphite powder is blocked by the blocking rod 123 and the spring support rod 124, and then the hydraulic cylinder 113 is started to extend, the sliding table 114 is pushed down, the extrusion rod 115 is lowered into the forming hole 122, and the graphite powder in the forming hole 122 is extruded to be formed into a graphite block.

[0081] Driving assembly 21 includes six through holes 215 opened in the inner wall of forming table 121, the top output end of electric telescopic rod 213 is fixedly connected with the bottom of connecting rod 214;

[0082] Among them, by starting the electric telescopic rod 213 to extend, the connecting rod 214 and the extrusion ring 212 are pushed up, when the extrusion ring 212 rises to cover the through hole 215, the gas in the annular groove 211 is extruded, and the gas is blocked by the jetting assembly 22, so that the gas pressure is increased.

[0083] Jetting assembly 22 includes plugging rod 224 slidingly connected to the inner wall of gas outlet groove 223, the side wall of six plugging rods 224 is rotatably connected with the inner wall of six connecting rods 222;

[0084] When the compression ring 212 rises, it also drives the fixed frame 221 to rise, pushing the connecting rod 222 to rotate and pulling the air-blocking rod 224 towards the fixed frame 221. As the air-blocking rod 224 continues to move, its left side will separate from the air outlet groove 223. Figure 5 As shown, at this time, the high-pressure gas in the annular groove 211 will be sprayed out to the surrounding area of ​​the graphite block through the gas outlet groove 223, reducing the adhesion between the graphite block and the forming hole 122, causing the graphite block to separate from the inner wall of the forming hole 122, thereby reducing the pushing force on the graphite block during demolding, effectively preventing the graphite block from developing micro-cracks due to excessive pushing force during demolding, avoiding the high temperature generated by graphitization from causing the cracks to increase, and ensuring the integrity of the graphite block during graphitization.

[0085] The blocking assembly 31 includes a beveled ring 313 that is slidably connected to the outer wall of the air-blocking rod 224, and four spring beveled plates 314 that are slidably connected to the inner walls of the six air-blocking rods 224.

[0086] When the extrusion ring 212 extrudes the gas, the gas first enters the inclined guide ring 311 and flows through the gap between the inclined guide ring 311 and the inclined ring 313, placing the inclined ring 313 in a high-pressure environment. At this time, the inclined ring 313 is in a stationary state. When the high-pressure gas is sprayed out from the outlet groove 223 onto the graphite block, the graphite block separates from the inner wall of the forming hole 122 around the outlet groove 223, and the gas sprayed out of the outlet groove 223 will escape outward. At this time, the gas flow rate in the outlet groove 223 will increase. When the gas flows along the gap between the inclined guide ring 311 and the inclined ring 313, it will generate a strong suction force on the inclined ring 313, attracting the inclined ring 313 to move, so that the inclined ring 313 contacts the inclined surface of the inclined guide ring 311, blocking the outlet groove 223, and causing the gas to concentrate and be sprayed out from the gas remaining outlet groove 223.

[0087] The pushing component 32 includes a rocker plate 324 rotatably connected to the inner wall of the blocking rod 123, a concave-convex rod 323 fixedly connected to the bottom of the forming table 121, and the outer walls of the four spring reset rods 322 are slidably connected to the inner walls of the four fixed cylinders 321.

[0088] When the high-pressure gas is ejected from the extrusion ring 212, the retracting electric telescopic rod 213 lowers the connecting rod 214 and the extrusion ring 212, causing the extrusion ring 212 to return to its original position. At this time, the electric telescopic rod 213 continues to retract, and the extrusion ring 212 will drive the forming table 121 to descend, causing the concave-convex rod 323 to descend, pushing the rocker arm 324 to rotate, pushing the spring support rod 124 to rise, and causing the graphite block to rise. When the concave-convex rod 323 separates from the rocker arm 324, the rebound force of the spring support rod 124 will be released, causing it to return to its original position. Since the graphite block slides in the forming hole 122, the forming hole 122 will limit the descent speed of the graphite block, causing the contact surface of the two to be slightly pulled. Through multiple rises and falls, the bottom of the graphite block and the top of the spring support rod 124 are slowly separated, effectively preventing the strong adhesion between the bottom of the graphite block and the top of the spring support rod 124 from causing a large pulling force when the graphite block is picked up, which would cause the bottom particles of the graphite block to fall off.

[0089] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0090] A specific application of this embodiment is as follows: When using this invention, the user adds graphite powder into the forming hole 122, allowing the graphite powder to be blocked by the blocking rod 123 and the spring support rod 124. Then, the hydraulic cylinder 113 extends, pushing the sliding table 114 down, causing the extrusion rod 115 to descend and enter the forming hole 122, extruding the graphite powder in the forming hole 122 and molding it into a graphite block. After the graphite block is formed, the hydraulic cylinder 113 retracts, causing the extrusion rod 115 to separate from the forming hole 122. After separation, the electric telescopic rod 2 is activated. 13 extends, pushing the connecting rod 214 and the compression ring 212 upward. When the compression ring 212 rises and covers the through hole 215, it will compress the gas in the annular groove 211. At this time, the compressed gas will be blocked by the air-blocking rod 224, so the gas pressure will increase. At the same time, when the compression ring 212 rises, it will also drive the fixed frame 221 to rise, pushing the connecting rod 222 to rotate and pulling the air-blocking rod 224 towards the fixed frame 221. As the air-blocking rod 224 continues to move, the left side of the air-blocking rod 224 will separate from the air outlet groove 223. Figure 5 As shown, at this time, the high-pressure gas in the annular groove 211 will be sprayed out to the surrounding area of ​​the graphite block through the gas outlet groove 223, reducing the adhesion between the graphite block and the forming hole 122, causing the graphite block to separate from the inner wall of the forming hole 122, thereby reducing the pushing force on the graphite block during demolding, effectively preventing the graphite block from developing microcracks due to excessive pushing force during demolding, avoiding the high temperature generated by graphitization from causing the cracks to increase, and ensuring the integrity of the graphite block during graphitization.

[0091] Secondly, when the extrusion ring 212 extrudes the gas, the gas will first enter the inclined surface flow guide ring 311, flow through the gap between the inclined surface flow guide ring 311 and the inclined surface ring 313, so that the inclined surface ring 313 is in a high-pressure environment. At this time, the inclined surface ring 313 is in a static state. When the high-pressure gas is sprayed out of the gas outlet groove 223 against the graphite block, the graphite block separates from the inner wall of the forming hole 122 around the gas outlet groove 223, and the gas sprayed out of the gas outlet groove 223 will escape outward. At this time, the gas flow rate in the gas outlet groove 223 will increase. When the gas flows along the gap between the inclined surface flow guide ring 311 and the inclined surface ring 313, it will generate a strong suction force on the inclined surface ring 313, attracting the inclined surface ring 313 to move, so that the inclined surface ring 313 contacts the inclined surface of the inclined surface flow guide ring 311, blocking the gas outlet groove 223, and making the gas concentrate and spray out of the remaining gas outlet groove 223. Effectively prevent the adhesion force of the graphite block to the inner wall of the forming hole 122 from being different in different areas, and the adhesion force in some areas is stronger, and the adhesion force in some areas is weaker. The area with weak adhesion will separate from the inner wall of the forming hole 122 first, so that the gas in the annular groove 211 concentrates and sprays out from this position, causing the gas to escape and affecting the thrust of the gas, making it difficult for the remaining area of the graphite block to separate from the forming hole 122;

[0092] Secondly, when the high-pressure gas in the extrusion ring 212 is sprayed out, the retractable electric rod 213 is retracted to lower the connecting rod 214 and the extrusion ring 212, so that the extrusion ring 212 returns to its original position. The through hole 215 will again communicate with the top of the extrusion ring 212, and the external gas will enter the top of the extrusion ring 212 through the through hole 215 to complete the replenishment of the gas. At this time, the retractable electric rod 213 continues to retract, and the extrusion ring 212 descends, which drives the forming table 121 to descend, so that the fixed cylinder 321 extrudes the spring return rod 322 to accumulate the elastic force. At the same time, when the forming table 121 descends, it also drives the concave-convex rod 323 to descend, so that the convex position of the concave-convex rod 323 contacts the flap 324, pushes the flap 324 to rotate, and makes the side of the flap 324 in contact with the concave-convex rod 323 descend and the other side rise. The rising side pushes the spring supporting rod 124 to rise and accumulates the elastic force;

[0093] When the convex position of the convex-concave rod 323 is separated from the flap 324, the spring support rod 124 will release the elastic force and return to its original position until the convex-concave rod 323 pushes the flap 324 to rotate again, and the spring support rod 124 rises. This process is repeated, and when the spring support rod 124 rises, it will drive the graphite block to rise. When the spring support rod 124 descends, the graphite block slides in the shaped hole 122, which limits the descending speed of the graphite block, causing the spring support rod 124 and the graphite block to have a speed difference, which slightly pulls the contact surface of the two. Through repeated lifting and lowering, the bottom of the graphite block and the top of the spring support rod 124 are slowly separated. As the forming table 121 continues to descend, the spring support rod 124 will push the graphite block out of the shaped hole 122. Then the graphite block is taken out. By slowly separating the spring support rod 124 and the graphite block, the adhesion between the bottom of the graphite block and the top of the spring support rod 124 is effectively prevented. When the graphite block is taken out, a large pulling force between the two will cause the particles at the bottom of the graphite block to fall off.

[0094] When the graphite block is demolded, the electric telescopic rod 213 is started again to extend, and the pressing ring 212 rises to the initial position. At this time, the pushing force on the forming table 121 disappears, and the spring return rod 322 releases the elastic force to push the forming table 121 back to its original position.

[0095] Secondly, when the air blocking rod 224 moves towards the fixed frame 221, it will drive the spring inclined plane plate 314 to contact with the inclined plane ring 313, push the inclined plane ring 313 to move, until the inclined plane ring 313 contacts with the blocking ring 312. At this time, the inclined plane ring 313 will be blocked, and the spring inclined plane plate 314 will continue to move, so that the inclined plane ring 313 will press the inclined plane of the spring inclined plane plate 314 to make it descend and accumulate elastic force. With the continuous movement of the air blocking rod 224, the spring inclined plane plate 314 will be separated from the inclined plane ring 313. By pushing the inclined plane ring 313 to move, it is ensured that the inclined plane ring 313 and the inclined plane flow guide ring 311 are in a separated state, effectively preventing the high-pressure gas in the annular groove 211 from pushing the inclined plane ring 313 and the inclined plane flow guide ring 311 to adhere closely, which will affect the flow of gas and the separation of the graphite block.
