Support legs 8 are fixedly installed at the four corners of the bottom of the support frame 1;

[0020] The limit guiding assembly 7 includes a positioning frame 9, and the positioning frame 9 is fixedly installed on the top of the support frame 1. In the middle of the top end of the positioning frame 9, a strip-shaped frame 10 is fixedly installed. Two symmetrical sides of the strip-shaped frame 10 are of an open structure. An adjusting motor 11 is fixedly installed on the top of the strip-shaped frame 10. An adjusting screw rod 12 is rotatably installed inside the strip-shaped frame 10. The output shaft of the adjusting motor 11 movably penetrates through the top of the strip-shaped frame 10 and is fixedly connected to the top of the adjusting screw rod 12. A threaded movable sleeve 13 is threadedly installed on the outer side of the bottom end of the adjusting screw rod 12. Symmetrically fixed on the outer side of the threaded movable sleeve 13 are positioning sliders 20. Positioning chutes 21 are symmetrically formed through the outer side of the strip-shaped frame 10, and the positioning sliders 20 slidably penetrate and are installed inside the positioning chutes 21. On both sides of the threaded movable sleeve 13 close to the open structures on both sides of the strip-shaped frame 10, first connecting shafts 14 are fixedly installed. Connecting bars 15 are rotatably installed on the first connecting shafts 14. Strip-shaped slots 16 are symmetrically formed through the inner part of the top end of the positioning frame 9, and one end of the connecting bar 15 away from the first connecting shaft 14 movably penetrates through the strip-shaped slot 16 and extends into the positioning frame 9. A second connecting shaft 17 is rotatably installed at one end of the connecting bar 15 away from the first connecting shaft 14. A strip-shaped limit frame 18 is fixedly installed at the bottom of the second connecting shaft 17. The two strip-shaped limit frames 18 are symmetrically arranged inside the positioning frame 9. The bottom of the strip-shaped limit frame 18 is in contact with the top of the conveyor belt 3.

At the same time, the threaded movable sleeve 13 drives the first connecting shaft 14 to move upward. The first connecting shaft 14 drives the connecting bar 15 to move inside the strip-shaped groove 16. The connecting bar 15 drives the strip-shaped limiting frame 18 to move through the second connecting shaft 17. The strip-shaped limiting frame 18 drives the positioning slide bar 22 to slide inside the side of the support frame 1, which can ensure better stability when the strip-shaped limiting frame 18 moves. At the same time, the strip-shaped limiting frame 18 drives the guide roller 19 inside it to move. After the distance between the guide rollers 19 inside the two strip-shaped limiting frames 18 is adapted to the width of the cardboard to be conveyed, stop the adjustment motor 11, and then start the conveying motor 2 to drive the driving roller shaft 4 to rotate. The driving roller shaft 4 drives the conveyor belt 3 to rotate. Then place the cardboard on the top of the conveyor belt 3, and convey the cardboard through the rotating conveyor belt 3. And through the guide rollers 19 inside the two strip-shaped limiting frames 18, the cardboard being conveyed can be limited and guided. In this way, during the use of the cardboard conveying device for carton production, it is convenient to limit and guide the cardboard according to the width of the cardboard to be conveyed, ensuring that the cardboard is conveyed neatly, so as to achieve better practicability.
