Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figures 1-5 As shown, this utility model provides a sintering device for additives in the production of pre-lithiated lithium battery precursors, including a support 1, a sintering mechanism 2 fixedly installed at the top of the support 1, and a leveling mechanism 3 that works in conjunction with the sintering mechanism 2 on the support 1. The sintering mechanism 2 includes a furnace body 21, which is fixedly installed on the top of the support 1. An array of perforated plates 22 are integrally formed in the inner cavity of the furnace body 21. A sintering box 23 is detachably sleeved on the perforated plates 22, and a rotating rod 24 and a rotating shaft 25 are rotatably inserted into the sintering box 23. An insert plate 218 is integrally formed in the middle of the perforated plates 22, and the bottom end of the sintering box 23 can slide onto the insert plate 218. The insert plate 218 ensures the stable installation of the sintering box 23. Symmetrically arranged handles 219 are fixedly installed at one end of the sintering box 23, and the outer wall of the handles 219 is covered with a protective layer. The anti-slip texture increases friction and facilitates operation. The rotating shaft 25 has a symmetrical structure, and symmetrically distributed rotating plates 26 are fixedly installed on the outer sides of both the rotating rod 24 and the rotating shaft 25. Synchronous pulleys 27 are fixedly sleeved on both the rotating rod 24 and the rotating shaft 25, and synchronous belts 28 are meshed and sleeved on the outer sides of adjacent synchronous pulleys 27. A stop bar 220 is rotatably installed on the upper side of one side of the sintering box 23, and the synchronous belt 28 can contact the stop bar 220. The use of the stop bar 220 can prevent the synchronous pulleys 27 and the synchronous belt 28 from disengaging. A sleeve plate 29 is fixedly connected to the end of the rotating rod 24. A rotating insert is placed on one side of the furnace body 21. A rotating column 210 is connected in an array, and an insert block 211 is fixedly connected to one end of the rotating column 210. The insert block 211 can be slidably inserted into the inner side of the sleeve plate 29. A bevel tooth 212 is fixedly fitted on the end of the rotating column 210 away from the sleeve plate 29. A servo motor 213 is fixedly installed on the lower end of one side of the furnace body 21, and a drive rod 214 is fixedly connected to the end of the output end of the servo motor 213. The drive rod 214 is rotatably inserted into the furnace body 21, and an array of bevel teeth 215 is fixedly fitted on the outer side of the drive rod 214. The bevel teeth 215 mesh with the bevel teeth 212. A fitting is hinged on one side of the furnace body 21. The furnace door 217 is used, and a sealing plate that works with the second bevel gear 215 is detachably provided on the other side of the furnace body 21. A vibration motor 216 is fixedly installed at the bottom of the furnace body 21 for use. The use of the furnace body 21 and the furnace door 217 together can sinter the materials inside. The use of the sealing plate can ensure that the first bevel gear 212 and the second bevel gear 215 work in a closed space. In addition, the servo motor 213 and the vibration motor 216 are all controlled by the PLC control module. The synchronous pulley 27 and the synchronous belt 28 are all high temperature resistant structures. These are all existing technologies and will not be described in detail here.

[0018] By adopting the above technical solution, when the additive sintering operation of the pre-lithiated lithium battery precursor production is carried out, the sintering box 23 containing an appropriate amount of additive is sequentially placed on the corresponding insert plate 218. During the placement of the sintering box 23, the corresponding rotating rod 24 needs to be rotated sequentially, thereby driving the corresponding sleeve plate 29 to rotate and place it on the outside of the corresponding insert block 211. Then, the furnace door 217 is closed and the furnace body 21 is started for sintering operation. During this period, the servo motor 213 can drive the drive rod 214 to rotate, thereby driving the rotating column 210 to rotate through the bevel gear 215 and bevel gear 212. Then, the insert block 211 and sleeve plate 29 can drive the rotating rod 24 and the corresponding rotating plate 26 to rotate. Furthermore, the synchronous wheel 27 and synchronous belt 28 can drive the rotating shaft 25 and the corresponding rotating plate 26 to rotate, thereby making the additive in sintering easy to turn over. After turning over, the servo motor 213 will be turned off and the vibration motor 216 will be started, thereby making the stacked additives evenly flattened.

[0019] The leveling mechanism 3 includes a lead screw 31, which is threaded into the four corners of the bottom end of the bracket 1. The bottom end of the lead screw 31 is rotatably sleeved with a support plate 32. Each of the four corners of the bottom end of the bracket 1 has a through screw hole 11, and the lead screw 31 is threaded into the screw hole 11. A rubber sleeve 34 is fixedly sleeved on the outside of the support plate 32. The rubber sleeve 34 is used to prevent slipping. A handwheel 33 is fixedly installed on the top of the lead screw 31.

[0020] By adopting the above technical solution, when using the sintering device, place it in a suitable position, and then turn the corresponding handwheel 33 according to the actual placement of the sintering device, so as to drive the corresponding screw 31 to rotate, and then drive the corresponding support plate 32 to move away from the support 1 until the sintering device is leveled.

[0021] Working principle: When in use, place the sintering device in a suitable position, and then turn the corresponding handwheel 33 according to the actual placement of the sintering device, which will drive the corresponding screw 31 to rotate, and then drive the corresponding support plate 32 to move away from the support 1 until the sintering device is leveled. During the additive sintering process in the production of pre-lithiated lithium battery precursors, a sintering box 23 containing an appropriate amount of additives is sequentially placed on the corresponding insert plate 218. During the placement of the sintering box 23, the corresponding rotating rod 24 is rotated sequentially, thereby driving the corresponding sleeve plate 29 to rotate and place it on the outside of the corresponding insert block 211. Then, the furnace door 217 is closed and the furnace body 21 is started for sintering. During this period, the servo motor 213 can drive the drive rod 214 to rotate, thereby driving the rotating column 210 to rotate through the bevel gear 215 and bevel gear 212. This, in turn, drives the rotating rod 24 and the corresponding rotating plate 26 to rotate through the insert block 211 and sleeve plate 29. Furthermore, the rotating shaft 25 and the corresponding rotating plate 26 can be driven to rotate through the synchronous wheel 27 and synchronous belt 28, thereby facilitating the turning of the additives during sintering. After turning, the servo motor 213 is turned off and the vibration motor 216 is started, thereby making the stacked additives evenly flattened.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
