DETAILED DESCRIPTION

[0020] The technical solution of the utility model is described clearly and completely below in conjunction with the specific embodiments of the utility model. The described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] like Figure 1-4As shown, the utility model provides a post-sintering pre-crushing device for lithium battery materials, comprising a frame 1 and a conveying platform 2 arranged on the frame 1 for conveying saggers, conveying rollers 10 for supporting and conveying the saggers are arranged on both sides of the conveying platform 2 along the conveying direction, a transmission shaft 11 is arranged at one end of the conveying platform 2, and a driven shaft 12 is arranged at the other end of the conveying platform 2, the transmission shaft 11 is connected with each conveying roller 10 and the driven shaft 12 in a driving manner, and a driving motor 13 for driving the transmission shaft 11 to rotate is further arranged on the conveying platform 2, so that each conveying roller 10 rotates synchronously with the transmission shaft 11 and the driven shaft 12 through belt transmission, and a suspended channel is formed between the conveying rollers 10 arranged on both sides of the conveying platform 2, and after the sagger passes through the driven shaft 12, its two ends are supported by the conveying rollers 10 on both sides of the conveying platform 2, so as to pass through the suspended channel above the conveying platform 2.

[0023] like Figure 3 As shown, a crushing member 3 for crushing materials in the sagger is arranged above the conveying platform 2, and the crushing member 3 includes a crushing table 32 and an elevator 31 for controlling the lifting and lowering of the crushing table 32. A plurality of rotating motors 4 are arranged at equal intervals on the crushing table 32. The rotating motor 4 of the present application adopts a small motor that can rotate forward and backward. A socket is arranged at the output end of the rotating motor 4, and the socket passes through the crushing table 32 and is arranged at the lower end of the crushing table 32. A crushing tool 6 made of titanium alloy is sleeved in the socket through a nut. The crushing tool 6 is made of The cutter 62 is composed of a handle 61 and a cutter 62, and the length of the handle 61 exposed outside the sleeve is smaller than the length of the cutter 62, thereby increasing its service life. The cutter 62 is concave in shape, and an incision is provided on the opposite side of the end of the cutter 62. The incision improves the cutting and crushing effect of the cutter 62 inserted into the material during the rotation process, and the crushing area is wide. At the same time, the cutter 62 contacts the material during the rotating operation, and its rotational force is greater than the resistance of contact with the material, thereby removing the material adhered to the sagger, thereby avoiding the material from adhering to the sagger, and further improving its crushing effect.

[0024] like Figure 1As shown, a lifting member is provided under the crushing member 3, so that the sagger is transported to the bottom of the crushing member 3 along the conveying platform 2 and then lifted to the crushing member 3 by the lifting member, thereby separating from the conveying platform 2; the lifting member includes a lifting cylinder 71 that produces a telescopic action along the plumb bob direction and a receiving platform 72 fixed on the top of the driving end of the lifting cylinder 71, and the receiving platform 72 is used to support the sagger when it rises and falls with the lifting cylinder 71. After the applicant's production test and debugging, it has been found that under normal conveying speed, when the material in the sagger is loaded with normal production volume, when the sagger moves to 2 / 3 of the sagger length below the crushing member 3, the driving motor 13 stops running, and the sagger can move just to the bottom of the crushing member 3 through the inertia of the sagger movement. After the lifting cylinder 71 receives the sagger in place signal, the lifting cylinder 71 slowly lifts the receiving platform 72, and the receiving platform 72 supports the sagger to the position of the crushing tool 6 of the crushing member 3, waiting for the cutter 62 to be crushed.

[0025] Example 2

[0026] On the basis of the above embodiment, in order to improve the service life of the crushing tool 6 and the sagger, the present embodiment is as follows: Figure 1 As shown, a plurality of guide posts 8 for connecting to the sagger are arranged at equal intervals on the upper end of the receiving platform 72 described in the present application, so that the receiving platform 72 contacts the sagger during the rising process of the lifting cylinder 71, and the guide posts 8 on the receiving platform 72 act on the corresponding connecting holes of the sagger (not shown in the figure), and the weight of the sagger is used to increase the stability of the connection, thereby preventing the material in the sagger from swinging during the crushing process, and improving the crushing effect of the crushing tool 6 on the material in the sagger.

[0027] Example 3

[0028] On the basis of the above embodiment, in order to reduce the generation of dust in the crushing production process and improve the comfort of the operating environment, the present embodiment is as follows: Figure 1 As shown, the length and width of the crushing table 32 described in the present application are greater than the length and width of the sagger, and a dustproof net 9 is provided on the edge of the lower end of the crushing table 32 corresponding to the sagger. During the crushing process, the sagger is completely covered in the dustproof net 9, thereby avoiding the scattering of dust generated during the crushing process and improving the comfort of the operating environment.

[0029] The conveying platform 2 described in the present application is also provided with an operation controller for the operation of the elevator 31, the rotating motor 4 and the driving motor 13. The present application sets the operation parameters of the elevator 31, the rotating motor 4 and the driving motor 13 according to actual production needs through the operation controller. The conveying platform 2 of the present application uses photoelectric control to transport the material in the sagger to the bottom of the crushing component 3, and then lifts the sagger to the crushing component 3 through the lifting component to separate the sagger from the conveying platform 2, and then drives the crushing tool 6 to crush the material in the sagger through the elevator 31, that is, the crushing tool 6 receives the material arrival signal, and the cutter 62 is slowly lowered by the elevator 31, and the rotating cutter 62 is operated until the cutter 62 extends into the inside of the sagger. The material is crushed, and stops descending when it is 1CM below the sagger to prevent the cutter 62 from damaging the sagger; when the cutter 62 reaches the position 1CM away from the sagger, the cutter 62 elevator 31 starts to rise, and at this time the cutter 62 starts to reverse to prevent the material from being brought out during the rotation and causing material waste; the cutter 62 rises and resets, and the cutter 62 stops running. At this time, the material in the sagger is crushed, and the conveying platform 2 receives the crushing signal of the cutter 62, the lifting cylinder 71 descends, and the sagger reaches the transportation position of the conveying platform 2 and starts to be transported to the next station; thereby effectively solving the problem that the existing lithium battery materials are bonded to the sagger during the crushing and cutting process after sintering, which makes it easy for the uncrushed materials bonded to the sagger to enter the kiln for sintering again.
