1. the present sheet stacking apparatus is mounted and used in cooperation with the conveying mechanism 8 as shown in fig. 1 according to the structural description of the above embodiment. The upper end face of the conveying belt of the conveying mechanism 8 is flush with the upper end face of the lifting plate 32 in the initial state, so that sheets on the conveying mechanism 8 are conveyed to the lifting plate 32 and are placed on the conveying belt of the conveying mechanism 8 at certain intervals;

2. the controller controls the guide rod of the lifting air cylinder 31 to extend to drive the lifting plate 32 and the sheet on the lifting plate 32 to move upwards, the sheet stays on the bending part 432 under the blocking of the bending part 432 of the check mechanism 4 after passing through the check mechanism 4, then the guide rod of the lifting air cylinder 31 retracts to enable the lifting plate 32 to move downwards to an initial position, the sheet is continuously conveyed onto the lifting plate 32 by the transmission mechanism 8, and the sheet is sequentially and circularly reciprocated to realize stacking of the sheet on the check mechanism 4;

3. when the sheets on the check mechanism 4 are stacked to a specified height and are required to be discharged, when the next sheet is not transmitted to the jacking plate 32, the controller controls the guide rods of the transverse air cylinders 52 to extend to enable the support frames 53 to enter between the two guide plates 2, then controls the guide rods of the vertical air cylinders 51 to extend to enable the support frames 53 to drive the stacked sheets to move upwards for a certain distance, and then controls the guide rods of the side pushing air cylinders 61 to extend to drive the side pushing plates 62 to push the stacked sheets to the temporary storage plates 71; in this process, since the stacked sheets are moved upward to a certain distance, the sheets can still be conveyed onto the lifting plate 32 by the driving mechanism 8 and lifted onto the non-return mechanism 4 by the lifting cylinder 31, thereby realizing continuous stacking of the sheets;

4. after the stacked sheets are pushed onto the temporary storage plate 71, the controller controls the guide rods of the side pushing cylinder 61, the lateral cylinder 52, and the vertical cylinder 51 to retract to the initial states, respectively.
