[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements.

The original plate 104 is fixedly connected to the multiple extrusion slides 103 by welding, and the limiting support plate 105 is arranged below the multiple extrusion vertical pipes 102.

[0031] Furthermore, a feeding pipe is vertically provided on the multi-channel feeding pipe 101, and a plurality of discharge pipes are provided below the multi-channel feeding pipes, which are fixedly connected and communicated with the multi-extrusion vertical pipes 102 respectively. Graphite powder can be added to the feeding pipe, and finally discharged through the plurality of discharge pipes and enter the multi-extrusion vertical pipes 102, and the graphite powder in the multi-extrusion vertical pipes 102 can be extruded by using the plurality of extrusion slides 103 to complete the processing of the graphite column, and the lifting of the associated original plate 104 can simultaneously drive the lifting of the plurality of extrusion slides 103, and the limiting support plate 105 can be used to seal the bottom of the multi-extrusion vertical pipes 102 to prevent the graphite powder from being directly discharged from the bottom of the multi-extrusion vertical pipes 102. The graphite powder is first added to the feeding pipe on the multi-channel feeding pipe 101, and finally discharged through the plurality of discharge pipes below the multi-channel feeding pipe 101 and enter the multi-extrusion vertical pipes 102. When the graphite powder fills the multi-channel feeding pipe 101, the graphite powder is discharged through the plurality of discharge pipes below the multi-channel feeding pipe 101 and enters the multi-extrusion vertical pipes 102. After the multiple extrusion vertical tubes 102 are extruded, the multiple extrusion slides 103 are driven downward by the associated original plate 104. When the extrusion slide 103 moves downward, the graphite powder in the multiple extrusion vertical tubes 102 will be extruded. After the graphite powder is extruded, it will become a graphite cylinder, and the processing of the graphite powder can be completed. At this time, the limiting support plate 105 is rotated to release the contact between the limiting support plate 105 and the multiple extrusion vertical tubes 102. At this time, the multiple extrusion slides 103 are driven downward by the associated original plate 104 to complete the secondary extrusion of the graphite powder processed in the multiple extrusion vertical tubes 102. At this time, the graphite cylinders in the multiple extrusion vertical tubes 102 will be extruded to complete the processing of the graphite column, which can be used as the positive electrode of a lithium battery, and the negative electrode of the battery is lithium metal or lithium alloy. The graphite column, the negative electrode of the battery and other materials are assembled to complete the processing of the lithium battery.

[0032] The following is combined with Figure 1-3 6, the processing system further includes a grinding chamber 201, a storage chamber 202 and a support leg 203. The grinding chamber 201 is fixedly connected to the storage chamber 202 by welding, the support leg 203 is fixedly connected to the grinding chamber 201 by welding, and the storage chamber 202 is fixedly connected to the multi-channel material pipe 101 by welding.

[0033] Furthermore, a plurality of leakage holes are provided below the grinding chamber 201, and a graphite block can be placed in the grinding chamber 201, and the graphite block is ground in the grinding chamber 201. When the graphite block is ground into powder, it will leak out through the plurality of leakage holes below the grinding chamber 201 and enter the storage chamber 202. A valve is provided on the storage chamber 202. After the valve is opened, the graphite powder entering the storage chamber 202 will enter the multi-channel material pipe 101, completing the addition of the graphite powder to the plurality of extrusion vertical tubes 102, completing the extrusion process of the graphite powder in the plurality of extrusion vertical tubes 102, and utilizing the support legs 203 to complete the fixing process of the grinding chamber 201, so that the entire device can be placed stably on the ground.

[0034] The following is combined with Figure 1-5 In detail, the processing system also includes a transverse support ring 301 and multiple telescopic rods I302. The transverse support ring 301 is fixedly connected to the grinding chamber 201 by welding, and the multiple telescopic rods I302 are fixedly connected to the transverse support ring 301 through flange plates. The original plate 104 is fixedly connected to the multiple telescopic rods I302 through flange plates, and the limiting support plate 105 is connected to the bottom of the transverse support ring 301 through axis rotation.

[0035] Furthermore, the transverse support ring 301 can provide a fixed space for multiple telescopic rods I302. Starting the multiple telescopic rods I302 can drive the associated original plate 104 to move downward, and the downward moving associated original plate 104 will drive the multiple extrusion slides 103 to move downward, thereby completing the extrusion processing of the graphite powder in the multiple extrusion vertical tubes 102. The transverse support ring 301 can also provide a rotation space for the limiting support plate 105, and can also limit the limiting support plate 105. A driving motor is fixedly connected to the transverse support ring 301, and the output shaft of the driving motor is fixedly connected to the limiting support plate 105. After starting the driving motor, the limiting support plate 105 will be driven to rotate, thereby changing the angle of the limiting support plate 105, thereby realizing the blocking and disengagement of the multiple extrusion vertical tubes 102, and the angle of the limiting support plate 105 is adjusted according to the processing conditions of the graphite powder.

[0036] According to the instruction manual Figure 1-3 6, the processing system also includes a cross support plate 401, a reduction motor 402 and a grinding roller 403. The cross support plate 401 is fixedly connected to the grinding chamber 201 by welding, the reduction motor 402 is fixedly connected to the cross support plate 401 through a flange plate, and the grinding roller 403 is fixedly connected to the output shaft of the reduction motor 402 through a coupling.

[0037] Furthermore, the cross support plate 401 can provide a fixed space for the reduction motor 402. After starting the reduction motor 402, it can drive the grinding roller 403 to rotate. When the grinding roller 403 rotates, the graphite block entering the grinding chamber 201 will be ground, thereby grinding the graphite block into graphite powder. By processing the graphite powder, the processing of the battery positive electrode graphite column can be completed.

[0038] According to the instruction manual Figure 1-3 6 , the processing system further includes a protection chamber 501 , which is fixedly connected to the cross support plate 401 by welding, and the reduction motor 402 is located inside the protection chamber 501 .

[0039] Furthermore, the top of the protective cavity 501 is designed with a conical structure. When the graphite block is added to the grinding cavity 201, it will contact the protective cavity 501 first, and the graphite block will not contact the reduction motor 402, preventing the graphite block from directly colliding with the reduction motor 402. When the graphite block hits the reduction motor 402, it may cause irreversible damage to the reduction motor 402.

[0040] According to the instruction manual Figure 1 and 8 -10 detailed description, the processing system also includes a coarse powder chamber 601, two toothed rollers 602 and two inner inclined plates 603.

Two driving members are fixedly connected to the coarse powder chamber 601, and the two driving members are respectively fixedly connected to the two toothed rollers 602. The two driving members can drive the two toothed rollers 602 to rotate, thereby realizing the extrusion and coarse crushing of the graphite blocks. The coarsely crushed graphite blocks will fall into the grinding chamber 201. After the grinding of the graphite blocks is completed, the workload of the grinding roller 403 is further reduced. After two inner inclined plates 603 are provided, the graphite blocks will fall onto the two inner inclined plates 603, and the graphite blocks will slide out through the two inner inclined plates 603, so that the graphite blocks will fall between the two toothed rollers 602.

[0042] According to the instruction manual Figure 1 and 8-10 Detailed description, the processing system also includes two scraping plates 701, the two scraping plates 701 are fixedly connected in the coarse powder chamber 601 by welding, and the two toothed rollers 602 are respectively in contact with the two scraping plates 701 and are slidably connected.

[0043] Furthermore, the two toothed rollers 602 can be cleaned by using two scraping plates 701. When the two toothed rollers 602 are coarsely powdering the graphite block, the graphite powder may stick to the two toothed rollers 602. By using the two fixed scraping plates 701 to contact the two rotating toothed rollers 602, the two toothed rollers 602 can be cleaned, further ensuring that the surfaces of the two toothed rollers 602 are in a clean state, thereby improving the extrusion effect on the graphite block.

[0045] Furthermore, a plurality of sliding posts are fixedly connected to the coarse powder chamber 601, the extrusion chamber 801 is slidably connected to the plurality of sliding posts, and a plurality of nuts are used to fix the extrusion chamber 801. The graphite block can be placed in the extrusion chamber 801 and slid into the oblique extrusion chamber 802. The graphite block entering the oblique extrusion chamber 802 is extruded and processed into a plurality of smaller graphite blocks. The small graphite blocks will enter the coarse powder chamber 601 through a plurality of coarse circular holes 803, and thus fall between the two tooth extrusion rollers 602. The smaller graphite blocks will further reduce the workload of the two tooth extrusion rollers 602 and extend the service life of the two tooth extrusion rollers 602.

[0046] According to the instruction manual Figure 1 and 8 -10 is described in detail. The processing system also includes a supporting frame 901, a telescopic rod II902 and a circular extrusion plate 903.

[0047] Furthermore, the supporting frame 901 can provide a fixed space for the telescopic rod II902. After starting the telescopic rod II902, the circular extrusion plate 903 will be driven to move downward. The circular extrusion plate 903 moving downward will be slidably connected to the oblique extrusion cavity 802 to realize the extrusion processing of the graphite block. The device processes the graphite block in three aspects through a step-by-step process. First, the graphite block is processed into smaller graphite blocks, and then the smaller graphite blocks are coarsely crushed. Finally, the coarsely completed graphite is ground. Through the stepped treatment of the graphite blocks, the parts can be protected and the service life of the parts can be further extended.
