[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0034] refer to Figure 1-2 A limiting mechanism of a carton binding machine includes a base 1. A recessed groove 2 is provided on the upper surface of the base 1. A plurality of conveying rollers 3 are evenly rotated in the recessed groove 2. When the carton moves on the conveying rollers 3, since the conveying rollers 3 can rotate freely, the smooth movement of the carton on the conveying rollers 3 can be ensured.

[0035] A U-shaped frame 4 is symmetrically fixed on the base 1, and slide plates 5 are slidably arranged on the two U-shaped frames 4. A limit rod 6 is symmetrically fixed between the two slide plates 5. A threaded rod 7 whose two ends are respectively rotatably matched with the two slide plates 5 is arranged between the two limit rods 6. A driving motor 8 is installed on one slide plate 5, and the output shaft of the driving motor 8 is connected to one end of the threaded rod 7. The driving motor 8 provides power for the threaded rod 7 to rotate.

[0036] A connecting plate 9 is arranged between the two slide plates 5, and the two ends of the connecting plate 9 are respectively connected to the upper ends of the two slide plates 5 by bolts. Extension plates 10 are arranged on both sides of the middle of the connecting plate 9, and a positioning rod 11 is symmetrically fixed on one side of the base 1. The positioning rod 11 passes through one side of the extension plate 10, which can ensure that the connecting plate 9 can slide vertically stably. A mounting groove 12 is provided on the side of the base 1 away from the positioning rod 11, and a lifting motor 13 is installed in the mounting groove 12. A lifting screw 14 is fixed on the output shaft of the lifting motor 13, and the lifting screw 14 is threadedly matched with the extension plate 10 on the other side. A motor protection block 15 is installed at the mounting groove 12 by bolts, and the motor protection block 15 protects the lifting motor 13.

[0037] refer to Figure 3-4An H-shaped block 16 is arranged between the two U-shaped frames 4, and the two limiting rods 6 both penetrate the H-shaped block 16. The H-shaped block 16 can slide along the limiting rod 6, and the threaded rod 7 is threadedly matched with the H-shaped block 16. The H-shaped block 16 is symmetrically fixed with inclined positioning blocks 17, and inclined rods 18 are symmetrically arranged at both ends of the H-shaped block 16. The inclined rod 18 is provided with a slide groove 19, and the positioning block 17 is in the slide groove 19, so that the inclined rod 18 can slide along the positioning block 17, and because the positioning block 17 is rectangular, the inclined rod 18 cannot rotate around the positioning block 17.

[0038] The lower end of the tilt rod 18 is in a vertical state, and a double-axis motor is fixedly installed in this end. The two output shafts of the double-axis motor are connected to rollers 22. When it is necessary to drive the carton to move, the rollers 22 need to descend to contact the carton, and the lifting motor 13 is started. The output shaft of the lifting motor 13 rotates to drive the lifting screw 14 to rotate. The lifting screw 14 rotates to drive the connecting plate 9 to move downward, and the connecting plate 9 drives the slide plate 5 to move downward. The two slide plates 5 drive the threaded rod 7 and the limit rod 6 between them to move downward. The threaded rod 7 and the limit rod 6 drive the H-block 16 to move downward, and the H-block 16 drives the roller 22 to move downward until the roller 22 contacts the surface of the carton. Then start the double-axis motor, and the output shaft of the double-axis motor rotates to drive the roller 22 to rotate. The rotation of the roller 22 drives the carton to move.

[0039] It is worth mentioning that when the tilt rods 18 on both sides move upward, they may touch each other. In order to increase the moving range of the tilt rods 18 so that the two tilt rods 18 will not block each other, it is specially arranged that a slot 23 is opened in the upper end surface of the two tilt rods 18, and the directions of the two slots 23 are inconsistent. When the two tilt rods 18 touch each other, the upper end of the tilt rod 18 will be embedded in the slot 23 of the other tilt rod 18, and the two will no longer cause obstruction.

[0040] Triangular blocks 24 are provided at both ends of the H-shaped block 16, and the triangular block 24 and the H-shaped block 16 are installed and connected by bolts. In particular, an inclined groove 25 is provided in the triangular block 24, and the width of the inclined groove 25 and the grooves at both ends of the H-shaped block 16 are consistent. A screw 26 is threadedly matched at the triangular block 24, and a pressure plate 27 is rotatably provided at the inner end of the screw 26. The width of the pressure plate 27 is consistent with the width of the inclined groove 25, so that the pressure plate 27 will not rotate in a direction perpendicular to the screw 26. A driving block 28 is fixed to the outer end of the screw 26. When the tilting rod 18 moves to the specified position, the driving block 28 is rotated, and the driving block 28 drives the screw 26 to rotate, and the screw 26 drives the pressure plate 27 to move toward the tilting rod 18 until the tilting rod 18 is pressed against the positioning block 17. At this time, the tilting rod 18 is positioned to prevent the tilting rod 18 from moving by mistake due to external force.

[0041] refer to Figure 5-6A side plate 29 is fixedly installed between the two U-shaped frames 4 by bolts, a baffle 30 is symmetrically arranged on the inner side of the side plate 29, one end of the baffle 30 is rotatably arranged on the inner side of the side plate 29, a T-shaped slot 31 is provided on the inner side of the baffle 30, a rotating cylinder 32 is symmetrically fixed on the outer side of the side plate 29, a threaded hole is provided in the rotating cylinder 32, and the threaded hole extends into the inner side of the side plate 29, an adjusting rod 33 is symmetrically arranged on the side plate 29, an external thread is provided on the outer surface of the adjusting rod 33, the adjusting rod 33 passes through the threaded hole, and the external thread matches the threaded hole, a round slide rod 34 is fixed on the inner end of the adjusting rod 33, and the round slide rod 34 The slide is set in the T-slot 31, and a driving block 2 35 is fixed to the outer end of the adjusting rod 33. When it is necessary to limit the cartons of different widths, the driving block 2 35 is rotated, and the driving block 2 35 drives the adjusting rod 33 to rotate. When the adjusting rod 33 rotates, it will move in a direction perpendicular to the side plate 29. With the cooperation of the circular slide bar 34 and the T-slot 31, the baffle 30 is driven to rotate inward, and the baffle 30 forms an inclined state. When the carton moves into the base 1, it will gradually approach the center along the baffle 30 until the closest ends of the baffles 30 on both sides limit the carton.
