[0023] This setting determines the size of the product and then drives the bidirectional electric push rod 23, so that the bidirectional electric push rod 23 drives the connecting plate 24 to move linearly, and the connecting plate 24 drives the L-shaped limit block 27 to move linearly to the appropriate position through the rotating block 25. When the product moves between the two mounting seats 21, the first electric push rod 111 is then driven, so that the first electric push rod 111 drives the mounting seat 21 to move linearly, and the mounting seat 21 drives the limit block 27 to rotate through the connecting plate 24, so that the limit block 27 drives the product to adjust its position through the first roller 28, and the product is straightened, so as to facilitate the subsequent process to accurately label the product.

[0025] One end of the connecting plate 24 is fixedly connected with a connecting tube 29 , which is slidably connected to the inner wall of the first mounting groove 22 to increase the support of the connecting plate 24 and prevent the bidirectional electric push rod 23 from being deformed due to a single force.
