A cake packaging apparatus according to claim 8, further comprising a cross cutting mechanism (7), the cross cutting mechanism (7) being disposed on a side of the slitting mechanism (6) in a running direction of the main roller (3), the cross cutting mechanism (7) being connected to the first controller, the first controller being further configured to control the cross cutting mechanism (7) to cut the cake at intervals for a set time.

10. A method of controlling a block packing apparatus for controlling the operation of a block packing apparatus (1) according to any one of claims 1 to 9, characterized in that the method comprises the steps of:

when the bottom film (23) is coated on the surface of the main roller (3), controlling the vacuumizing device to start, and adsorbing the bottom film (23) in a die cavity (31) of the main roller (3);

After the mask (46) and the bottom film (23) are sealed, the vacuumizing device is controlled to be closed, so that the bottom film (23) contracts under the action of self-pulling force, and the blocks are tightly packed.
