Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 The present invention provides the following technical solution:

[0029] A cutting device for packaging box production includes a clamping device 1 and a metal frame 2. A connecting frame 3 is installed on the top of the metal frame 2. An electric push rod 5 is installed on the inner wall surface of the connecting frame 3. A cutting blade 4 is installed at the bottom of the piston rod inside the electric push rod 5. The clamping device 1 is installed at the left and right ends of the metal frame 2.

[0030] The clamping device 1 includes a connecting plate 11, a limiting block 12, and a connecting assembly 13. The limiting block 12 is threadedly connected to the top of the connecting plate 11. The connecting plate 11 is slidably connected to the left and right ends of the metal frame 2. The limiting block 12 is slidably connected to the top surface of the metal frame 2. The limiting block 12 and the connecting plate 11 slide on the top of the metal frame 2, which facilitates the removal of the connecting plate 11 and the limiting block 12 from the metal frame 2, thereby enabling the disassembly and replacement of the connecting plate 11 and the limiting block 12. The connecting assembly 13 is installed on the surface of the connecting plate 11.

[0031] The connecting assembly 13 includes a clamping plate 131, a plug-in frame 132, a coil spring 133, a second connecting plate 134, a connecting block 135, an electric push rod 136, a moving roller 137, and a sliding frame 138. The clamping plate 131 is inserted into the interior of the second connecting plate 134, the plug-in frame 132 is inserted into the bottom of the second connecting plate 134, the connecting block 135 is slidably connected to the inner wall surface of the second connecting plate 134, the connecting block 135 is inserted into the bottom of the piston rod inside the electric push rod 136, and the connecting block 135 is slidably connected to the surface of the plug-in frame 132. The connecting block 135 slides on the surface of the plug-in frame 132, while the second connecting plate 134 can limit the connecting block 135, thereby allowing the connecting block 135 to be inserted into the connecting plate 134. The connection between the connecting plate 134 and the electric push rod 136 facilitates the disassembly and replacement of the connecting plate 134. The sliding frame 138 and the electric push rod 136 are connected by a threaded rod. The sliding frame 138 consists of an upper metal cover plate and a lower metal cover plate. A fastening threaded rod is fixedly connected to the inner bottom surface of the lower metal cover plate. A moving roller 137 is movably connected to the surface of the fastening threaded rod. The lower metal cover plate, the upper metal cover plate, and the bottom of the connecting plate 11 are movably connected, thereby enabling the electric push rod 136 to be limited. The moving roller 137 is installed inside the sliding frame 138 and is tactilely connected to the inner wall surface of the connecting plate 11. The sliding frame 138 is slidably connected. At the bottom of connecting plate 11, sliding frame 138 and moving roller 137 roll on the surface of connecting plate 11, adjusting the position of electric push rod 136 to clamp and fix cardboard boxes of different sizes. Helical spring 133 is fixedly connected to the bottom of connecting block 135 and installed on the inner wall surface of connecting plate 134. Insertion frame 132 is located inside helical spring 133. Helical spring 133 can push connecting block 135 back and forth on the inner wall surface of connecting plate 134, allowing connecting block 135 to insert into the connection between connecting plate 134 and electric push rod 136, facilitating the disassembly and replacement of connecting plate 134. There are four electric push rods 136, with two electric push rods 136 forming one unit. The system consists of four sets of electric push rods 136, one set arranged horizontally and the other two sets arranged front-to-back on the same side. These four electric push rods 136 are controlled by a PLC controller, allowing them to push together. A connecting block 135 is slidably connected to the inner wall of a connecting plate 11. The connecting block 135 slides on the inner wall of a clamping plate 131, allowing it to engage with the connection between the electric push rods 136 and the connecting plate 134. This enables the clamping plate 131 to be disassembled and replaced. There are two connecting plates 11, located on the left and right sides of the metal frame 2. These connecting plates 11 can move the electric push rods 136 left and right, thus clamping and securing the packaging box.It facilitates the clamping and securing of packaging boxes of different sizes.

[0032] When using, place the packaging box on the inner bottom surface of the metal frame 2, and align the area to be cut directly below the cutting blade 4.

[0033] Pulling the electric push rod 136 causes the sliding frame 138 and the moving roller 137 to slide on the bottom of the connecting plate 11. At the same time, when the sliding frame 138 and the moving roller 137 slide on the surface of the connecting plate 11, the wear of the connecting plate 11 and the sliding frame 138 can be reduced.

[0034] Pulling the connecting plate 11 and the limiting block 12 causes them to slide on the top of the metal frame 2, which adjusts their positions and thus the position of the connecting assembly 13.

[0035] When the electric push rod 136 is activated, it can push the connecting plate 134 and the clamping plate 131 to move downward. The clamping plate 131 clamps and fixes the top of the packaging box, thus limiting and fixing the packaging box.

[0036] When the electric push rod 25 is activated, the internal piston rod of the electric push rod 25 can push the cutting blade 4 downward, and the cutting blade 4 can perform cutting operations on the packaging box, making it convenient to cut and process the packaging box.

[0037] Pull the clamping plate 131 outward to disengage it from the connecting plate 134, making it easy to remove and replace the clamping plate 131.

[0038] Next, pull the plug-in frame 132, which can detach from the connecting plate 134 and the connecting plug 135, thus loosening the connection of the connecting plug 135.

[0039] Pull the connecting plug 135 outward, and the connecting plug 135 slides on the inner wall surface of the connecting plate 134. At the same time, the connecting plug 135 and the connecting plate 134 can compress the helical spring 133, making it easy to disassemble and replace the connecting plug 135 and the helical spring 133.

[0040] This allows the clamping plate 131 to be disassembled and replaced.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
