[0024] The following further describes the present utility model in detail with reference to the embodiments:

[0025] As Figures 1-5 shown, the present utility model provides a cutting device for processing paper packaging boxes, including a cutting table 1. Support feet 2 are symmetrically and fixedly installed at the four corners of the cutting table 1. A machine frame 3 is fixedly installed in the middle of the upper end of the cutting table 1. Two groups of hydraulic cylinders 4 are fixedly installed on the top of the machine frame 3. The lower end of the output rod of the hydraulic cylinder 4 is fixedly installed with a mounting block 5. An installation frame 6 is movably sleeved outside the mounting block 5. The lower end of the installation frame 6 is fixedly connected with a cutting knife 7. Disassembly and assembly mechanisms 8 are symmetrically connected to both sides of the upper end of the cutting knife 7. A dust suction mechanism 9 is installed at the lower end of the cutting table 1. Triangular blocks 10 are symmetrically and fixedly connected to both side end faces of the upper end of the cutting table 1. An electric push rod 11 is fixedly connected to the inside of the triangular block 10. The front end of the output rod of the electric push rod 11 is fixedly connected with a top block 12. A connecting rod 13 is slidably connected to the middle of the top block 12. A first spring 14 is sleeved outside the lower end of the connecting rod 13. A pressing plate 15 is fixedly installed at the lower end of the connecting rod 13. A handle 16 is fixedly installed at the upper end of the connecting rod 13.

[0026] One end of the first spring 14 is fixedly connected to the lower side of the top block 12, and the other end is fixedly connected to the upper side of the pressing plate 15.

[0027] A cutting groove is formed on the middle surface of the cutting table 1, and the cutting groove is located directly below the cutting knife 7.

[0028] The hydraulic cylinder 4 can drive the cutting knife 7 to move up and down, facilitating the adjustment of the height of the cutting knife 7 and facilitating the cutting of cardboard. The cutting knife 7 provided on the cutting table 1 can prevent the cutting knife 7 from directly contacting the table surface and prevent damage to the cutting knife 7. The pressing plate 15 can fix the cardboard under the elastic action of the first spring 14, thereby preventing the cardboard from moving and affecting the cutting quality.

[0029] As Figure 3 shown, the disassembly and assembly mechanism 8 includes positioning holes 81. Positioning holes 81 are penetrated between the mounting block 5 and the installation frame 6. Side plates 82 are symmetrically and fixedly connected to both sides of the upper end of the cutting knife 7. A pull rod 83 is slidably installed inside the side plate 82. A second spring 84 is sleeved outside the bottom end of the pull rod 83. A pull handle 85 is fixedly installed at the top end of the pull rod 83. A limiting plate 86 is fixedly installed at the bottom end of the pull rod 83. A positioning column 87 is fixedly connected to the bottom end of the limiting plate 86.

[0030] One end of the second spring 84 is fixedly connected to the inner side of the side plate 82, and the other end is fixedly connected to the front side of the limiting plate 86.

[0031] The positioning column 87 is matched with the positioning hole 81 and is movably installed.

[0032] By fitting the installation block 5 into the installation frame 6, the positioning holes 81 in the middle of the installation block 5 and the installation frame 6 are aligned. Then, under the elastic action of the second spring 84, the limiting plate 86 and the positioning post 87 can be pushed towards the installation frame 6, so that the positioning post 87 can be directly inserted into the positioning hole 81, thereby limiting the installation block 5 and the installation frame 6, enabling the cutting knife 7 to be installed and facilitating use.

[0033] The disassembly and assembly structure facilitates the user to perform maintenance operations on the cutting knife 7, enabling the user to easily disassemble the cutting knife 7 for maintenance work, effectively avoiding wear, dullness, or other faults caused by the long-term lack of maintenance of the cutting knife 7, thereby affecting the use effect of the entire device.

[0034] As Figures 4-5 As shown in the figure, the dust suction mechanism 9 includes a bottom frame 91. The upper end of the bottom frame 91 is fixedly connected to the middle part of the lower end of the cutting table 1. Through holes 92 are respectively formed in the left and right sides of the bottom frame 91. A collection box 93 is fixedly installed inside the bottom frame 91. A dust suction fan 94 connected in communication is fixedly installed at the lower right end of the collection box 93. Pad blocks 95 are symmetrically and fixedly connected to both end faces on the upper side of the cutting table 1. A dust suction hood 96 is fixedly connected to the upper side of the pad blocks 95. Dust suction pipes 97 connected in communication are symmetrically and fixedly connected to both sides of the collection box 93. Installation frames 98 are symmetrically and fixedly installed on both inner walls of the collection box 93. A filter plate 99 is movably installed inside the installation frames 98.

[0035] The dust suction pipe 97 passes through the through hole 92 and is fixedly connected to the rear end of the dust suction hood 96 and is in communication.

[0036] The installation frame 98 is in an inverted "U" shape, and a box door is movably hinged to the front end of the collection box 93.

[0037] The filter plate 99 in the collection box 93 can filter the debris to prevent the debris from damaging the dust suction fan 94. By opening the box door, it is convenient to clean the inside of the collection box 93.

[0038] By transporting the debris into the collection box 93 for centralized storage, in this way, the accumulation and dispersion of debris in the working area are avoided, not only keeping the working environment clean, but also greatly improving the use effect of the device.

[0039] Next, the working principle of the cutting device for processing paper packaging boxes will be specifically described.

[0040] As Figures 1-5As shown, when the cutting device for processing paper packaging boxes is in use, first, the electric push rods 11 on both sides can be started, so that the electric push rods 11 can drive the top blocks 12 to move, and then the distance between the left and right top blocks 12 can be adjusted, so as to fix cardboard of different sizes. Then, pull the handle 16 upward, so that the handle 16 drives the connecting rod 13 to move synchronously, and the connecting rod 13 drives the pressing plate 15 to move, thereby squeezing the first spring 14. Then, place the cardboard of the packaging box to be cut on the cutting table 1, and then release the handle 16. Under the action of the first spring 14, the pressing plate 15 can be pushed downward, so that the pressing plate 15 presses and fixes the cardboard. Then, the hydraulic cylinder 4 can be started, so that the hydraulic cylinder 4 pushes the cutter 7 downward, so that the cutter 7 can cut the cardboard, and then the cutting operation of the cardboard of the packaging box can be completed; and debris will be generated during cutting. At this time, the dust suction fan 94 can be started, so that the dust suction fan 94 can absorb the debris on the cutting table 1 through the dust suction pipe 97 and the dust suction cover 96, and centrally transport it into the collection box 93 for convenient centralized treatment; and when maintaining the cutter 7, the hydraulic cylinder 4 can be made to drive the cutter 7 to reset. Then, the user can pull the pulling handles 85 on both sides outward at the same time, so that the pulling handles 85 drive the pull rods 83 to move, and the pull rods 83 drive the positioning columns 87 to move through the limiting plates 86, so that the positioning columns 87 are separated from the positioning columns 87 in the middle of the mounting block 5 and the mounting frame 6. Then, the user moves the cutter 7 downward, and then the cutter 7 drives the mounting frame 6 to be separated from the mounting block 5, so that the cutter 7 can be disassembled, which is convenient for maintaining the cutter 7 and avoiding affecting the use effect of the device.

[0041] The above generally describes the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
