[0002] A packaging box is a box used to package products. Paper packaging boxes are the most common. The function of packaging boxes is to ensure the safety of products during transportation and improve the grade of products. In the process of processing paper packaging boxes, cutting devices are usually used to cut the cardboard.

[0003] The cutting blade of the existing packaging carton cutting device is connected to the blade holder by bolts. The cutting blade and the blade holder connected by bolts need to be disassembled with the help of tools (such as a wrench or a screwdriver). This increases the complexity and time required for disassembly. For production lines that need to frequently replace the cutting blades, this inconvenience may significantly affect production efficiency and ease of operation. In addition, bolts, as connecting parts, are easily worn or damaged during frequent disassembly and reinstallation. Once the bolts are damaged, new bolts need to be replaced, which further increases maintenance costs and downtime. At the same time, the existing packaging carton cutting device cannot accurately adjust the cutting length of the packaging box. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0018] See also Figure 1-5 The utility model provides a packaging paper box cutting and processing device, including a workbench 1, a bracket 2, two cylinders 3, a mounting plate 4 and two knife seats 5. The workbench 1 is provided with a cutting hole 9, the bracket 2 is arranged on the workbench 1, the two cylinders 3 are arranged on the outer top of the bracket 2, and the driving ends of the two cylinders 3 movably penetrate the top of the bracket 2, the mounting plate 4 is arranged on the driving ends of the two cylinders 3, the two knife seats 5 are arranged at the bottom of the mounting plate 4, and two connecting mechanisms 6 are respectively arranged on the two knife seats 5. The outer side walls of the two knife seats 5 are connected with cutting components 7 through the connecting mechanisms 6.

[0019] Specifically, the connecting mechanism 6 includes a support box 61, a threaded sleeve 62, a screw 63, a movable plate 64, a bearing 65 and two blocks 66. The support box 61 is arranged on the left side outside the tool holder 5, the threaded sleeve 62 is arranged on the left side outside the support box 61, the screw 63 is connected to the threaded sleeve 62, the top and bottom of the movable plate 64 are respectively slidably connected to the top and bottom of the support box 61, the bearing 65 is arranged on the left side of the movable plate 64, and the inner ring of the bearing 65 is interference fit with one end of the screw 63, and the two blocks 66 are arranged on the right side of the movable plate 64, and the two blocks 66 are movable through the left side of the tool holder 5.

[0020] Specifically, the cutting assembly 7 includes a cutting knife 71, two connecting frames 72 and two mounting seats 73. The two connecting frames 72 are arranged on the top of the cutting knife 71, and the two mounting seats 73 are arranged on the top of the two connecting frames 72. Each mounting seat 73 has two card slots. The two mounting seats 73 are respectively movably inserted into the two knife seats 5, and the two mounting seats 73 are connected to the knife seats 5 through the connecting mechanism 6.

[0021] Specifically, an adjustment component 8 is provided on the workbench 1 .

[0022] Specifically, the adjustment assembly 8 includes two support plates 81, a screw rod 82, a slide rail 83 and a limit plate 84. The two support plates 81 are arranged at the bottom of the workbench 1. The two ends of the screw rod 82 are rotatably connected to the two support plates 81 respectively.
