[0019] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides a technical solution: a cardboard cutting device for packaging carton processing, comprising a frame 1, a belt conveyor mechanism 2 is arranged inside the frame 1, a hydraulic cylinder 3 is arranged on the top of the frame 1, a movable frame 4 is fixedly connected to the bottom of the piston rod of the hydraulic cylinder 3, a driving motor 5 is fixedly connected to the side wall of the movable frame 4, an output shaft of the driving motor 5 is fixedly connected to a driving shaft 6 through a coupling, a cutting knife 7 is fixedly connected to one end of the driving shaft 6, and a fixing block 8 is fixedly connected to the inner wall of the movable frame 4.

[0021] A receiving groove 9 is provided inside the fixed block 8, and a telescopic spring 10 is fixedly connected to the inner wall of the receiving groove 9, and a limiting block 11 is fixedly connected to the bottom of the telescopic spring 10, and a movable protrusion 12 is fixedly connected to the outer wall of the limiting block 11, and a positioning block 13 is fixedly connected to the outer wall of the movable protrusion 12. By arranging a frame 1, a belt conveyor mechanism 2, a hydraulic cylinder 3, a movable frame 4, a drive motor 5, a drive shaft 6, a cutting knife 7, a fixed block 8, a receiving groove 9, a telescopic spring 10, a limiting block 11, a movable protrusion 12 and a positioning block 13, it is convenient to position the carton during trimming, thereby solving the problem of incorrect cutting caused by the deviation of the carton during trimming, thereby improving the accuracy of trimming, meeting people's work needs, and worthy of popularization and use.

[0022] Furthermore, the movable frame 4 is distributed in a "concave" shape, and the movable frame 4 forms a sliding structure with the frame 1 through the hydraulic cylinder 3, which facilitates the movable frame 4 to be driven to rise and fall.

[0023] Furthermore, two cutting knives 7 are provided, and the two cutting knives 7 form a rotating structure through the driving shaft 6 and the movable frame 4, which facilitates the trimming work on both sides of the carton at the same time.

[0024] Furthermore, the limit block 11 forms a telescopic structure with the accommodating groove 9 through the telescopic spring 10, and the limit block 11 and the movable protrusion 12 are distributed in a "T" shape, which facilitates the limit block 11 to reset and slide.

[0025] Furthermore, the bottom of the movable protrusion 12 passes through the bottom wall of the fixed block 8, and the movable protrusion 12 is slidably connected to the fixed block 8, which facilitates the movable protrusion 12 to drive the positioning block 13 to slide.

[0026] Furthermore, the positioning block 13 and the movable protrusion 12 are arranged in a "T" shape, and the bottom of the positioning block 13 is lower than the bottom of the cutting knife 7, which facilitates positioning of the carton when trimming the edges through the positioning block 13.

[0027] When in use, the carton is first transported to a suitable position through the belt conveyor mechanism 2, and then the hydraulic cylinder 3 is started to drive the movable frame 4 to descend, so that the movable frame 4 drives the cutting knife 7 to contact with the carton. In this process, the positioning block 13 contacts with the carton before the cutting knife 7, so that the positioning block 13 drives the movable protrusion 12 to slide after being squeezed, so that the movable protrusion 12 drives the limit block 11 to slide, and the limit block 11 drives the telescopic spring 10 to compress. When the cutting knife 7 contacts with the carton, the elasticity of the telescopic spring 10 drives the limit block 11 to reset and slide, so that the limit block 11 drives the positioning block 13 to reset and slide through the movable protrusion 12, so that the positioning block 13 positions the carton, thereby solving the problem that the carton is prone to offset during edge trimming and improving the stability of edge trimming. After the subsequent drive motor 5 is started, the drive shaft 6 drives the cutting knife 7 to rotate to complete the edge trimming work.
