[0036] The components of this embodiment that are the same as or corresponding to those in the above embodiment are marked with the same reference numerals as those in the above embodiment. For the sake of simplicity, only the differences from the above embodiment are described below. The differences between this embodiment and the above embodiment are:

[0037] Preferably, the variable driving mode of the limiting portion 21 in the height direction is active driving or passive driving.

[0039] As a preferred embodiment, when a passive drive mode is adopted, Figure 1-2 As shown, it also includes: a height adjustment mechanism 3, which is arranged below the carrier 2, and gradually lifts up the limit part 21 vertically along the transmission direction so that the effective limit height of the limit part 21 is adapted to the thickness of at least one group of wrapped plate groups 10 carried on the carrier 2.

[0040] As a preference, Figure 3 As shown, the height adjustment mechanism 3 is arranged along the horizontal transport direction of the conveying mechanism 1 and its length is adapted to the horizontal transport stroke of the conveying mechanism 1 .

[0041] As a preference, Figure 4 As shown, the height adjustment mechanism 3 includes: a lifting section 31, which is in an overall upslope shape along the transmission direction, and the bottom of the limiting portion 21 contacts the lifting section 31 and is gradually lifted during the transmission process.

[0042] Furthermore, the present embodiment is used for automatic stacking and automatic output of the wrapped plate groups 10 during the transmission process. A plurality of workstations for placing the wrapped plate groups 10 are distributed in the horizontal transmission direction of the conveying mechanism 1. By further setting the limiting portion 21 as a vertically movable structure and cooperating with a sloped height adjustment mechanism 3 arranged along the horizontal transmission direction of the conveying mechanism 1, the limiting portion 21 is gradually lifted up by the height adjustment mechanism 3 during the transmission process. When reaching each stacking station on the transmission path, the lifting height of the limiting portion 21 is adapted to the thickness of a group of wrapped plate groups 10, so as to cooperate with each workstation to be in a low position on the carrier 2 to stack and place the wrapped plate groups 10, thereby avoiding damage caused by high-position placement, and timely limiting the front and rear sides of the newly stacked wrapped plate groups 10.
