Description

[0001] The present application is a divisional application of the invention patent application with the application number of 202210566546.8, the title of which is "Preparation of lithium battery material with a sagger machine and lithium battery material sintering equipment", and the filing date of which is May 24, 2022. TECHNICAL FIELD

[0002] The present application relates to the technical field of new energy battery preparation, in particular to a sagger machine for preparing lithium battery materials. BACKGROUND

[0003] At present, for the lithium battery material sintering equipment for preparing the positive and negative electrodes of lithium batteries, the polar material needs to be loaded into a special sagger and pushed into a sintering furnace for sintering. Due to the high-temperature characteristics of the sintering furnace, the powdery material such as graphite powder coming out of the sintering furnace will condense and solidify after high-temperature drying. The material condensed into blocks in the subsequent section cannot meet the production requirements. The phenomenon that such blocky material directly enters the subsequent section will greatly limit the production efficiency and product yield for the subsequent section. Therefore, a special material breaking device is needed to break and crush the blocky material to restore it to a powdery state. Before breaking and crushing, the sagger sintered in the kiln needs to be transported to the breaking processing station by a conveying device. In the prior art, the sagger is directly broken and crushed at each breaking processing station in sequence, so the pushing force in the breaking process is easy to cause damage to the conveying device, and even cause damage to the sagger, especially lacking a limiting mechanism for the sagger, so that the sagger is easy to shift during the breaking and crushing process, resulting in that part of the blocky material cannot obtain the action force of the blade and thus the breaking and crushing effect is poor. In addition, the movement mechanism configured by the material breaking device is relatively complex, resulting in that the whole machine is not compact, and there are disadvantages of low automation degree and low breaking and crushing efficiency.

[0040] Please further refer to Figure 5, specifically, each telescopic mechanism 50 further comprises a baffle 55 arranged at the free end of one of the guide rods 54 and a guide frame 57 fixed on the machine plate 11, a plurality of detectors 58 with a transmitter and a receiver are arranged on the guide frame 57, the plurality of detectors 58 include an uppermost detector, a lowermost detector and an intermediate detector corresponding to the driving plate 53 being farthest away from, closest to and intermediate to the inner bottom wall of the sagger 1 respectively, the baffle 55 moves between the uppermost detector and the lowermost detector, so that the determination of whether the baffle 55 blocks the signal by the uppermost detector and the lowermost detector ensures that the blade assembly 60 moves in a predetermined range, and the intermediate detector corresponds to the initial contact of the blade assembly 60 with the agglomerated material to perform the breaking and crushing, so that when the intermediate detector determines that the baffle 55 has blocked the signal, the conveying motor 21 can drive the movement of the blade assembly 60 in the operating mode corresponding to the breaking and crushing process, especially, at this time, the above-mentioned vibrator 70 can start to work, in addition, preferably, the positions of the above-mentioned detectors 58 on the guide frame 57 can be adjusted according to actual needs, so as to adapt to different sizes of the sagger 1, different thicknesses of the agglomerated material and the like. The displacement sensor 25 and the telescopic motor 51, the conveying motor 21, the lifting motor 34 and each cylinder are electrically connected with the controller, the controller controls the shutdown of the conveying motor 21 and the opening of the second cylinder 41 and the third cylinder 43 to position the sagger 1 according to the displacement threshold data of the sagger 1 detected by the displacement sensor 25 being conveyed to the most upstream waiting lifting position in the conveying direction, and then the lifting motor 34 is opened until the sagger 1 is lifted to the breaking position and the lifting motor 34 is turned off and the two first cylinders 37 are opened so that a pair of supporting blocks 39 move into the lifting plate 31, then the controller controls the telescopic motor 51 to work according to the preset program to drive the blade assembly 60 to enter the inside of the sagger 1 to break and crush the agglomerated material, after the breaking and crushing process is completed, the telescopic motor 51 is controlled to work to drive the blade assembly 60 to exit the inside of the sagger 1, finally, the two first cylinders 37 are opened so that the pair of supporting blocks 39 move out from below the lifting plate 31, and the lifting motor 34 is opened until the sagger 1 is lowered to return to the waiting lifting position, then the lifting motor 34 is turned off and the conveying motor 21 is controlled to be opened to further convey the sagger 1 to the next waiting lifting position until the most downstream waiting lifting position in the conveying direction, the above-mentioned operation control is repeated at each waiting lifting position and breaking position, that is, the corresponding lifting movement, advancing and retreating movement and positioning force are repeatedly controlled and executed, that is, after the sagger is conveyed from one waiting lifting position to the next waiting lifting position, another sagger is conveyed to the one waiting lifting position, finally, the conveying mechanism 20 conveys the sagger 1 to the next process.For example, for the case of three block breaking devices, the conveying mechanism sequentially conveys the sagger to the corresponding waiting lifting position and block breaking position of the first block breaking device, the second block breaking device and the third block breaking device in the conveying direction, so that the caked material is sequentially subjected to block breaking and crushing treatment by the first blade, the second blade and the second blade. In addition, it can be understood that during the driving movement of the sagger 1 between the corresponding waiting lifting position and block breaking position, the sagger 1 can move in the state of being pressed and limited, because the elastic blocks 45 arranged on the side pressing plates 42 and the end pressing plates 44 have elastic deformation amount.

Since the rectangle side where each first blade 61 is located is in close proximity to the inner wall of the saggar, the outer circumferential surface of the caked material is completely separated from the inner wall of the saggar. The second blade assembly 60" includes a second blade 62 arranged through the midpoint of the rectangle and a third blade 63 vertically symmetrical with respect to the center line of the second blade 62.
