At the same time, the air suction frame and the air suction pipe will have a cooling effect on the cutter to prevent the cutter temperature from being too high and affecting the lithium metal.

[0010] According to the above technical scheme, a purification plate is fixedly installed inside the air intake frame, and the inhaled air can be purified by the purification plate to prevent the toxic air generated when the lithium metal is cut from randomly dispersing and causing danger.

[0014] According to the above technical solution, a circular block is fixedly installed on the surface of the pressing plate, and a pulling rod is fixedly installed on the surface of the supporting frame. The pulling rod will push the pressing plate and the circular block to move up and down. A No. 2 spring is arranged between the pressing plate and the bending plate.

[0015] The present invention provides a slitting machine for lithium battery processing, which has the following beneficial effects:

[0016] (1) The invention drives the extrusion plate to rotate by rotating the shaft. When the extrusion plate rotates, the protrusion drives the contact block and the sealing plate to move. When the sealing plate moves upward, the pushing block moves upward. When the pushing block moves upward, it pushes the cut position of the lithium metal to separate, so as to avoid that the bottom of the lithium metal is not completely separated after being cut. At the same time, when the sealing plate moves upward, it squeezes the air inside the support plate to spray out, and the air spray blows the detached lithium metal through the filter plate and moves it to the collection plate.

[0017] (2) The invention can scrape off the lithium metal adhered to the surface of the cutter through the scraper and the arc frame to prevent the lithium metal from adhering to the surface of the cutter and affecting the cutting effect of the lithium metal. At the same time, the suction frame and the suction pipe can cool the cutter to prevent the cutter temperature from being too high and affecting the lithium metal. It can also adsorb toxic gases. When the lithium metal is prevented from spontaneous combustion due to contact with the air, the spontaneously combusting lithium metal will be sucked into the interior of the suction frame and burn the hollow rubber, making the hollow rubber unable to support the positioning plate. The positioning plate will release the limit on the limit plate and the screen plate, and the screen plate will drive the lithium metal inside the suction frame to move to the left to prevent the lithium metal inside the suction frame from being ignited.

[0018] (3) In the present invention, when lithium metal spontaneously combusts, the limit plate moves to release the limit on the connecting rod, cutting plate and connecting frame, so that when the cutting plate moves downward, it will cut and separate the lithium metal, preventing the spontaneously combusting lithium metal from igniting the entire lithium metal. At the same time, when the cutting plate drives the storage frame to move downward, the push rod will push the valve to rotate and open the storage frame. The flame-retardant gas inside the storage frame will be ejected from the jet plate to extinguish the lithium metal.

[0019] (4) In this invention, when the extrusion plate and the protrusion rotate, the arc block will push the protrusion and the extrusion plate to move. When the extrusion plate moves, it will drive the bending plate to move. The movement of the extrusion plate and the bending plate will correct and position the lithium metal, and prevent the position of the lithium metal from being offset after being cut. When the bending plate moves, the pulling rod will push the pressing plate and the circular block to move up and down. When the pressing plate moves up and down, it will press the edge of the lithium metal to prevent the edge of the lithium metal from being deformed after being cut. BRIEF DESCRIPTION OF THE DRAWINGS

The impact block 48 moves, and when the impact block 48 moves, it will collide with the impact plate 49, so that the pushing block 46 will vibrate when it moves, the extrusion plate 41 is slidably installed on the surface of the rotating shaft 31, the protrusion 42 is fixedly installed on the surface of the extrusion plate 41, the sealing plate 44 is slidably installed inside the support plate 33, the contact block 45 is fixedly installed on the top of the sealing plate 44, the pushing block 46 is fixedly installed on the top of the sealing plate 44, the filter plate 47 is fixedly installed on the top of the support plate 33, the impact block 48 is fixedly installed on the surface of the pushing block 46, and the impact plate 49 is fixedly installed on the bottom of the inner wall of the support plate 33. When the pushing block 46 moves upward, it will push the cut position of the lithium metal to separate, so as to avoid the lithium metal being not completely separated after being cut. The vibration generated by the pushing block 46 can improve the effect of separating the lithium metal.

[0034] A spring No. 1 is provided between the sealing plate 44 and the support plate 33 . A collecting plate 410 is fixedly mounted on the surface of the sealing plate 44 , and the separated lithium metal can be collected by the collecting plate 410 .

[0035] The scraping device includes an air suction frame 51, a fixed rod 52, an arc frame 53, a scraper 54 and an air suction pipe 55. When the cutter 32 rotates, the lithium metal adhered to the surface of the cutter 32 will be scraped off under the action of the scraper 54 and the arc frame 53. The air suction frame 51 is fixedly installed on the surface of the support frame 1, the fixed rod 52 is fixedly installed on the bottom of the air suction frame 51, the arc frame 53 is fixedly installed on the bottom of the fixed rod 52, the scraper 54 is fixedly installed on the surface of the arc frame 53, and the air suction pipe 55 is fixedly installed on the surface of the arc frame 53. An exhaust fan is fixedly installed on the surface of the air suction frame 51 to prevent the lithium metal from adhering to the surface of the cutter 32 and affecting the effect of cutting the lithium metal. At the same time, the air suction frame 51 and the air suction pipe 55 will have a cooling effect on the cutter 32 to prevent the cutter 32 from being overheated and affecting the lithium metal.

[0036] A purification plate 57 is fixedly installed inside the air intake frame 51. The purification plate 57 can be used to purify the inhaled air to prevent the toxic air generated when the lithium metal is cut from randomly dispersing and causing danger. A sieve plate 56 is slidably installed on the inner wall of the air intake frame 51. A force storage spring is arranged between the sieve plate 56 and the air intake frame 51. A limit plate 58 is fixedly installed on the surface of the sieve plate 56. A groove is provided at the bottom of the limit plate 58. A locking plate 510 is rotatably installed inside the groove. A hollow rubber 59 is fixedly installed inside the groove. The limit plate 58 slides through the air intake frame 51. The hollow rubber 59 and the locking plate 510 can limit the sieve plate 56. After the self-igniting lithium metal is sucked into the air intake frame 51, the hollow rubber 59 will be burned. The sieve plate 56 will drive the lithium metal inside the air intake frame 51 to move to the left to prevent the lithium metal inside the air intake frame 51 from being ignited.

[0037] When the present embodiment is working, when the lithium metal moves on the guide wheel 2 and the support plate 33, the rotation shaft 31 drives the cutter 32 to rotate, and the lithium metal is cut into strips. When the rotation shaft 31 rotates, it drives the extrusion plate 41 and the protrusion 42 to rotate. When the protrusion 42 rotates, it pushes the contact block 45 and the sealing plate 44 to move. The upward movement of the sealing plate 44 drives the push block 46 to move upward. When the push block 46 moves upward, it pushes the cut position of the lithium metal to separate. When the push block 46 moves, it drives the impact block 48 to move. When the impact block 48 moves, it collides with the impact plate 49, so that the push block 46 will vibrate when it moves. At the same time, when the sealing plate 44 moves upward, it squeezes the gas inside the support plate 33 to discharge, which has a cooling effect. At the same time, the detached lithium metal will move to the collecting plate 410 through the filter plate 47.

[0038] When the cutter 32 rotates, the lithium metal adhered to the surface of the cutter 32 will be scraped off under the action of the scraper 54 and the arc frame 53. At the same time, the cutter 32 will be cooled by the air suction frame 51 and the air suction pipe 55. At the same time, some lithium metal will be sucked into the interior of the air suction frame 51, and the lithium metal will be separated by the sieve plate 56. At the same time, the purification plate 57 will purify the toxic air. The lithium metal will spontaneously combust when being cut. The spontaneously combusting lithium metal will be sucked into the interior of the air suction frame 51 and burn the hollow rubber 59. The hollow rubber 59 will not be able to rotate the positioning plate 510 due to leakage caused by the combustion. Under the action of the storage spring, the limit plate 58 and the sieve plate 56 will be driven to move, so that the limit plate 58 will push the positioning plate 510 to rotate toward the inside of the groove to release the limit on the limit plate 58. When the sieve plate 56 moves, it will push the lithium metal inside the air suction frame 51 to move.

[0039] See also Figure 1-11On the basis of the above embodiment, another embodiment of the present invention further includes a disconnecting device and a resetting device. The surface of the support frame 1 is provided with a disconnecting device, and the disconnecting device includes a cutting plate 61, a connecting frame 62 and a connecting rod 63. When the through hole moves to the bottom of the connecting rod 63, the limit plate 58 will not be able to support the connecting rod 63. When the cutting plate 61 moves downward, the lithium metal will be cut and separated. The cutting plate 61 is slidably mounted on the surface of the support frame 1, and the connecting frame 62 is fixedly mounted on the top of the cutting plate 61. The connecting rod 63 is fixedly mounted on the surface of the connecting frame 62. A through hole is opened on the surface of the limit plate 58, and a reset spring is arranged between the cutting plate 61 and the support frame 1 to prevent the self-igniting lithium metal from igniting the lithium metal as a whole.

When the cutting plate 61 moves downward, it will drive the storage frame 65 and the valve 67 to move downward. When the valve 67 moves downward, it will contact the push rod 64, so that the push rod 64 will push the control end of the valve 67 to rotate and open the valve 67. The valve 67 is connected with the inside of the jet plate 66 through a pipeline, and the flame-retardant gas inside the storage frame 65 will be ejected from the jet plate 66 to extinguish the lithium metal.

[0041] The reset device includes an arc block 43, a bending plate 71 and a pressing plate 73. The arc block 43 will push the protrusion 42 and the extrusion plate 41 to move. When the extrusion plate 41 moves, it will drive the bending plate 71 to move. The arc block 43 is fixedly installed on the surface of the support frame 1, and the bending plate 71 is slidably installed on the surface of the support plate 33. The surface of the bending plate 71 is slidably connected to the extrusion plate 41. The pressing plate 73 is slidably installed on the surface of the bending plate 71. When the bending plate 71 moves, it will correct and position the lithium metal, and at the same time avoid the position of the lithium metal being offset after being cut.

[0042] A circular block 74 is fixedly installed on the surface of the pressing plate 73, and a pulling rod 72 is fixedly installed on the surface of the support frame 1. The pulling rod 72 will push the pressing plate 73 and the circular block 74 to move up and down. A No. 2 spring is arranged between the pressing plate 73 and the bending plate 71. When the pressing plate 73 moves up and down, it will press the edge of the lithium metal to prevent the edge of the lithium metal from being deformed after being cut.

[0043] When the embodiment is working, the limit plate 58 will drive the through hole to rotate when it moves. When the through hole moves to the bottom of the connecting rod 63, the limit plate 58 will not be able to support the connecting rod 63. Under the action of the reset spring, the cutting plate 61, the connecting frame 62 and the connecting rod 63 will be driven to move downward. When the cutting plate 61 moves downward, the lithium metal will be cut and separated. When the cutting plate 61 moves downward, the storage frame 65 and the valve 67 will be driven to move downward. When the valve 67 moves downward, it will contact the push rod 64, so that the push rod 64 will push the control end of the valve 67 to rotate and open the valve 67, so that the flame-retardant gas inside the storage frame 65 will be ejected from the jet plate 66 to extinguish the lithium metal.

[0044] When the extrusion plate 41 and the protrusion 42 rotate, they will contact the arc block 43, so that the arc block 43 will push the protrusion 42 and the extrusion plate 41 to move. When the extrusion plate 41 moves, it will drive the bending plate 71 to move. When the bending plate 71 moves, it will drive the pressing plate 73 to move. When the pressing plate 73 moves, it will drive the circular block 74 to move. When the circular block 74 moves, it will contact the pulling rod 72, so that the pulling rod 72 will push the pressing plate 73 and the circular block 74 to move up and down.
