[0002] After the production of corrugated paper is completed, it is necessary to cut grooves on its edges. The current cutting method is to stack the produced corrugated paper together and cut grooves on its edges by the saw blade on the groove cutting machine. Chinese patent CN220719479U discloses a new type of corrugated paper cutting machine. Through the use of a bearing platform, a longitudinal adjustment mechanism, a transverse adjustment mechanism, a pressing plate mechanism and a spacing adjustment component, the stacked corrugated paper can be well clamped, and the longitudinal feeding method can be realized to avoid the arc blade, improve the cutting effect of the corrugated paper, and facilitate the forward and backward movement of the clamped corrugated paper to adjust the cutting position, and the cutting depth of the groove cutting machine on the corrugated paper can also be adjusted. However, the above-mentioned prior art requires that the corrugated paperboards be manually transported to the bearing platform piece by piece and stacked neatly, and then manually fixed and pressed before the cutting work can be carried out. After the cutting is completed, it needs to be transported down and stacked again. During the transportation and manual alignment and pressing, the cutting work cannot be carried out, the equipment downtime is long, and the operation efficiency is not high. Therefore, in order to solve the defects of the above-mentioned prior art, it is necessary to design an automatic corrugated cardboard cutting device. Utility Model Content

If the corrugated cardboard is not neatly stacked during loading, the alignment can be corrected by the two positioning components 326.

[0039] The blocking assembly 34 includes a blocking cylinder 341 and a blocking plate 342.

The feeding conveying mechanism 31 forms a buffer station through a number of blocking components 34, providing the operator with sufficient loading preparation time. At the same time, the translational inertia of the corrugated cardboard 5 can be weakened by a number of blocking components 34, avoiding rebound when it abuts against the blocking component 34, resulting in uneven stacking of the corrugated cardboard 5. It should be noted that the rebound phenomenon can also be avoided by reducing the conveying speed of the feeding conveyor belt 311 to ensure that the corrugated cardboard 5 always remains neat during the conveying process.

[0043] A plurality of avoidance grooves 3211 are arranged at intervals on one side of the loading platform 321 facing the slot cutting machine 2. The avoidance grooves 3211 are for avoiding the saw blade of the slot cutting machine 2 to avoid collision.
