[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0015] like Figures 1 to 3 As shown, a carton feeding adjustment structure for a carton stapling machine includes two sets of spaced-apart fixed frames 1. Between the two sets of fixed frames, from bottom to top, are a fixed plate 2, a transmission screw 3, and a fixed rod 4. Limit adjustment structures for adjusting carton feeding are provided on the fixed plates, transmission screw, and fixed rods. Specifically, the limit adjustment structure includes a rear plate 6 slidably connected to the fixed plate, with the sliding direction being the length direction of the fixed plate. A limit plate 7 is slidably connected vertically to the front side of the rear plate. A fixed block 14 is also provided behind the rear plate, with a threaded hole through which the transmission screw passes and connects. A positioning plate 10 is provided on the upper rear side of the limit plate, and the positioning plate can be C-shaped. A positioning sleeve 11 is provided on the positioning plate 10, through which the fixed rod passes and abuts. An adjustment plate 12 is provided on the upper rear side of the limit plate 7, and the adjustment plate is horizontally arranged. An adjustment bolt 13, which passes vertically through the adjustment plate, is screwed onto the adjustment plate, with the lower end of the adjustment bolt abutting against the positioning plate. The rear plate is slidably connected to the fixed plate in such a way that a slider 15 is provided on the rear side of the rear plate, and a groove is provided on the fixed plate, within which the slider slides in a limited manner. Two sets of fixed plates can be provided.

[0016] Furthermore, there are two sets of transmission lead screws 3 and two sets of limit adjustment structures. Each transmission lead screw corresponds to one limit adjustment structure. An intermediate plate 18 is provided between the two sets of transmission lead screws. The intermediate plate is also connected to a fixed plate and a fixed rod, and the connection can be made via an external connector. Specifically, the intermediate plate 18 and the fixed frame 1 are equipped with bearing structures. The bearing structures connect to the transmission lead screws, and the fixed frame is also equipped with a drive motor to rotate the lead screws, thereby driving the left and right adjustment of the rear plate and the limit plate. The intermediate plate has two sets of bearing structures, which are used to connect the two sets of transmission lead screws on both sides. There are two drive motors, each connected to a transmission lead screw. The drive motors are reversible motors.

[0017] Furthermore, the rear plate 6 has two sets of forward-arranged single plates 8 at its front center. The sides of the single plates that are close to each other have protrusions. The limiting plate has single grooves running from top to bottom on both end faces. The protrusions engage with the single grooves 9. The single plates and protrusions have transverse through-holes with positioning bolts. The limiting plate slides up and down on the rear plate using the protrusions and single grooves.

[0018] Furthermore, the upper part of the limiting plate 7 is provided with a waist-shaped through hole 16, and the positioning plate is provided with a positioning screw hole. A connecting bolt 17 is provided at the positioning screw hole. The connecting bolt passes through the waist-shaped through hole and is connected to a connecting nut.
