[0015] S2: The conveyor belt drives the pallet to move and adjusts the pallet through the centering device, and then continues to move. When it contacts the blocking block, the conveyor belt stops;

[0016] S3: The electric push rod drives the mobile control board through the support plate and the fixed column to reach the specified position, and lifts the pallet through the fork rod for stacking;

[0017] S4: The stacked pallets will squeeze the push plate and open the blocking block. The stacked pallets will be placed on the conveyor belt through the electric push rod. Finally, the pallets will be pushed to the outside through the anti-blocking device and transported by a forklift.

[0018] The present invention has the following beneficial effects:

[0019] (1) In the present invention, when the pallet passes through the centering device, the electric push rod 2 starts to work and pulls the rectangular block to move to the right. When the rectangular block moves to the right, it pulls the rotating rod to rotate and pulls the U-shaped connecting plate 1 to move inward. When the U-shaped connecting plate 1 moves inward, it pushes the arc-shaped push plate to move the inner side together. When the arc-shaped push plate moves inward, it pushes the rotating plate to move to both sides through the trapezoidal slider a. When the rotating plate moves to both sides, it pushes the extrusion plate to move to the middle of the main body through the trapezoidal slider b, thereby aligning the pallet. It can ensure that the pallet can be adjusted to the correct position quickly and accurately, and prevent the pallet on the conveyor belt from being placed in an inclined state, which will cause unstable stacking during subsequent stacking. This reduces the time and effort of manual adjustment and improves the overall stacking efficiency.

[0020] When the L-shaped fixed block moves outward, it will eventually push the anti-roll plate to move inward to clamp the stacked pallets, which can ensure that the pallets can be neatly arranged when stacked, avoiding tilting, misalignment, etc., which would cause the stacking to be unstable or collapse, thereby improving the overall stability of the stacking.

[0021] (3) In the present invention, when the number of pallets reaches a certain level, when the fork rod supports the pallet to rise, the uppermost pallet will squeeze the movable plate 2 to make it move upward, and when the movable plate 2 moves upward, it will push the push plate to move to both sides, and when the push plate moves to both sides, it will push the sliding block to move to both sides together, and when the sliding block moves, it will push the L-shaped movable plate to move outward, and drive the swing plate to rotate through the straight slot, thereby driving the blocking block to rotate, and when the L-shaped movable plate moves outward, the round rod on the left side of the L-shaped movable plate will move together, and when the round rod moves, it will slide along the parallelogram rectangular groove opened on the right side of the square block. When the blocking block is opened, the round rod will move along the rectangular slot to the bottom of the rectangular slot, and will be moved downward by the reaction force of the spring at the top of the second moving plate, thereby pulling the round rod to move along the bottom of the rectangular slot on the right side of the square block. When the round rod moves at the bottom of the rectangular slot, it will contact the moving oblique block, and due to the spring on one side of the moving oblique block, the round rod will slowly move inward. When the round rod moves to the corner at the bottom of the rectangular slot, it will move obliquely upward, and the blocking block will return to its original position under the drive of the L-shaped moving plate, blocking the pallet again, which can assist the stacking device to position the pallet more accurately, achieve fast and efficient stacking, and avoid the situation where the pallet moves too forward, which makes the fork rod unable to stack the pallet.

[0022] (4) In the present invention, when the stacked pallets fall on the sliding plate, the sliding plate is affected by the weight of the pallets and moves downward. When the sliding plate moves downward, the push-pull plate inside the sliding groove on the top of the sliding plate moves upward relative to the sliding plate. When the stacking device centers the pallet, the electric push rod 2 pulls the rectangular block to move it to the right, thereby pushing the U-shaped connecting plate 2 and causing the U-shaped moving plate to move to the right. When the U-shaped moving plate moves, it drives the push-pull plate to move together, thereby pushing the pallet above the sliding plate to move it toward the outside. The anti-blocking device can be used to push out the stacked pallets after the pallets are stacked to make room for new pallets, thereby avoiding the occurrence of blockage. This is of great significance for improving production efficiency and ensuring smooth logistics.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the electric The movable push rod 201 drives the mobile control plate 204 to move downward through the support plate 202 and the fixed column 203, and places the stacked pallet on the conveyor belt 102 through the fork rod 205, and starts the conveyor belt 102, thereby driving the stacked pallet to move to the right and finally fall on the sliding plate 602. At this time, the round rod 509 moves to the corner at the bottom of the rectangular groove and moves obliquely upward. The blocking block 506 will return to its original position under the drive of the L-shaped moving plate 504 and block the pallet again. When the stacked pallet falls on the sliding plate 602, the sliding plate 602 is affected by the weight of the pallet, The sliding plate 602 will move downward. When the sliding plate 602 moves downward, the push-pull plate 604 inside the top chute of the sliding plate 602 will move upward relative to the sliding plate 602. When the stacking device 2 aligns the pallet, the second electric push rod 301 will pull the rectangular block 302 to move to the right, thereby pushing the second U-shaped connecting plate 606 and causing it to move the U-shaped movable plate 605 to move to the right. When the U-shaped movable plate 605 moves, it will also drive the push-pull plate 604 to move together, thereby pushing the pallet above the sliding plate 602 to move outward.
