Description

Automatic centering structure of empty pallet Technical Field The invention relates to the technical field of conveying platforms of logistics systems of die cutting machines, in particular to an automatic centering structure of an empty pallet. Background In the existing empty pallet (tray) placing structure of the paper collection logistics of the die cutting machine, the action of placing the empty pallet (tray) is manually placed by an operator, and the placing action is required to be completed in a shorter operation time, so that the left and right positions of the empty pallet (tray) relative to a logistics conveying platform are random and cannot be centered, and the periphery of a paper pile after paper collection is offset and misplaced relative to the pallet (tray) and cannot be centered. Adverse to the smooth operation of the subsequent logistics and also influences the automatic operation of the logistics system. The utility model CN211920167U discloses an automatic pallet stacking positioning device, a first cylinder pushes a piston rod to lock a pallet in a pallet placing area, and finally, a left cylinder and a right cylinder drive pressing blocks to be close to the middle, so that the pallet can be placed in the pallet placing area, the width of the pallet which can be operated by the device is limited by the size of each part, and the operation of the pallets with different widths can not be realized through adjustment.
