[0027] Further, the opening areas of the two shells 1 are connected to the area of the pallet, at this time, the two push rods 4 of the shell 1 are relatively parallel to the two sides of the corner of the pallet, at this time, the shell 1 installed at the other diagonal position is parallel to the other two sides of the corner of the pallet through the other two push rods 4 connected thereto, at this time, all four sides of the pallet are covered.

[0028] Further, since the two ends of the connecting rod 202 are respectively connected with the driving turntable 2 and the push rod 4, and the bottom of the push rod 4 is further slidingly connected with the shell 1 through the sliding groove 6, a crank connecting rod structure is formed, so that the driving turntable 2 drives the bearing 201 to move in a circular arc shape when rotating, and the front end of the connecting rod 202 moves along with the bearing 201, at this time, the tail end of the connecting rod 202 moves along with the second bearing 3, since the sliding rail 401 exists at this time, the moving track between the second bearing 3 and the connecting rod 202 does not have hard friction, and the push rod 4 also moves linearly under the driving of the connecting rod 202, once the push rod 4 starts to move, it moves along the track of the sliding groove 6, moves in the opening of the shell 1 and touches the carton on the pallet, further, since the four push rods 4 move on four different sides of the pallet at the same time, it is equivalent to fixing the areas of the four sides of the pallet at the same time, so that the corners of the carton are all positioned in the areas, and automatic alignment is completed.

When the upper sliding push rod 442 moves, it will contact the conical body 445 behind it. Since the conical body 445 is from low to high, the upper sliding push rod 442 will move forward under the support of the stroke groove 443 and the stroke sliding block 444, and at this time the stroke sliding block 444 compresses the spring. The upper sliding push rod 442 moving forward relative to the movement trajectory of the carton on the pallet can more effectively align it. Further, when the push rod 4 is reset, the spring will push the stroke sliding block 444 back to move the upper sliding push rod 442 connected thereto back to reset.

[0033] In use, the opening regions of the two housings 1 are butted to the pallet region, at which time the two push rods 4 of the housing 1 are relatively parallel to the two sides at the corners of the pallet, completing preliminary installation, further driving the output end of the speed reducer motor to rotate back and forth by 45 degrees, so that the driving turntable 2 is automatically reset after rotating to 45 degrees, since the connecting rod 202 has two ends respectively connected to the driving turntable 2 and the push rod 4, and the bottom of the push rod 4 is also slidably connected to the housing 1 through the slide 6, thereby forming a crank connecting rod structure, so that the driving turntable 2 drives the bearing 201 to move in a circular arc shape when rotating, and as the bearing 201 moves with the front end of the connecting rod 202, the tail end of the connecting rod 202 moves with the second bearing 3, since there is a slide rail 401 at this time, the movement trajectory between the second bearing 3 and the connecting rod 202 will not have hard friction, and the push rod 4 will also move linearly under the driving of the connecting rod 202, and once the push rod 4 starts to move, it will move along the track of the slide 6, moving at the opening of the housing 1 and touching the carton on the pallet, further since the four push rods 4 are moving on four different sides of the pallet at the same time, it is equivalent to fixing the areas of the four sides of the pallet at the same time, and the driving turntable 2 is automatically reset after rotating to 45 degrees, so as to achieve the linear reciprocating motion of the four push rods 4, thereby repeatedly pushing the corners of the carton to finally complete alignment, so that the corners of the carton are all positioned in this area, completing automatic alignment.
