[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0023] Combine Figure 1 、 Figure 3 and Figure 5 A cutting device for packaging cartons includes a support plate 1, a top plate 2 fixedly connected to the inner side of the support plate 1, a conveying assembly 4 arranged below the top plate 2, a first electric push rod 3 fixedly connected to the bottom end of the top plate 2, a knife holder 31 fixedly connected to the bottom end of the first electric push rod 3, and a cutting knife 311 fixedly connected to the bottom end of the knife holder 31, a first trough 21 fixedly connected to the bottom end of the top plate 2, a cleaning assembly 6 is arranged below the first trough 21, and a groove 11 is opened on one side of the support plate 1.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example 1:

[0026] See also Figures 1-6The cleaning assembly 6 includes a first motor 61 fixedly connected to one end of the first trough 21, a threaded rod 62 fixedly connected to the output end of the first motor 61, a first connecting plate 63 threadedly connected to the outer surface of the threaded rod 62, a fixing plate 64 fixedly connected to the bottom end of the first connecting plate 63, a first mounting plate 65 and a second mounting plate 66 fixedly connected to the top of the fixing plate 64, and a first cleaning brush 67 fixedly connected to one side of the first mounting plate 65 and the second mounting plate 66. The first cleaning brush 67 is movably connected to the outer surface of the cutting blade 311. One end of the threaded rod 62 is rotatably connected to the inner wall of the first trough 21, and the other end of the threaded rod 62 passes through the first trough 21. The first motor 61 is disposed inside the groove 11. The threaded rod 62 is driven to rotate by the first motor 61, and the rotation of the threaded rod 62 drives the first connecting plate 63 and the fixing plate 64 to move, thereby driving the first mounting plate 65, the second mounting plate 66 and the first cleaning brush 67 to move. The first cleaning brush 67 moves along the outer surface of the cutting blade 311 to facilitate cleaning the outer surface of the cutting blade 311.

[0027] The top of the fixed plate 64 is fixedly connected to a second connecting plate 642. The bottom of the top plate 2 is fixedly connected to the second trough 22. The slide bar 221 is fixedly connected inside the second trough 22. The second connecting plate 642 is slidably connected to the outer surface of the slide bar 221. When the threaded rod 62 rotates to move the first connecting plate 63 and the fixed plate 64, the second connecting plate 642 slides along the outer surface of the slide bar 221, acting as a guide.

[0028] The conveyor assembly 4 includes a first support leg 41 and a second support leg 42, a second rotating rod 43 that rotates through the second support leg 42, a second motor 45 fixedly connected to one side of the first support leg 41, a first rotating rod 44 fixedly connected to the output end of the second motor 45, and a conveyor belt 46 that is transmission-connected to the outer surfaces of the second rotating rod 43 and the first rotating rod 44. The first rotating rod 44 rotates through the first support leg 41. The second motor 45 drives the first rotating rod 44 to rotate, and the conveyor belt 46 also drives the second rotating rod 43 to rotate. At this time, the conveyor belt 46 continuously conveys, facilitating the conveyance of the carton to the cutting blade 311 for cutting.

[0029] A second cleaning brush 641 is fixedly connected to the bottom end of the fixed plate 64, and the bottom end of the second cleaning brush 641 contacts the top end of the conveyor belt 46. When the threaded rod 62 rotates to drive the first connecting plate 63 and the fixed plate 64 to move, the second cleaning brush 641 moves along the top end of the conveyor belt 46, facilitating the cleaning of debris on the top end of the conveyor belt 46.

[0030] A waste collection box 5 is provided inside the support plate 1. A fixing block 51 is fixedly connected to one side of the waste collection box 5. A locking bolt 511 is threadedly connected between the fixing block 51 and the support plate 1. The waste collection box 5 is used to collect waste chips. The waste collection box 5 is fixed to the support plate 1 by the locking bolt 511. Removing the locking bolt 511 allows the waste collection box 5 to be separated from the support plate 1, thereby facilitating the disposal of the waste chips inside the waste collection box 5.

[0031] The inner wall of the waste collecting box 5 is fixedly connected to a second electric push rod 52, and the telescopic end of the second electric push rod 52 is fixedly connected to a push plate 521. The telescopic second electric push rod 52 drives the push plate 521 to move, so as to squeeze the waste chips inside the waste collecting box 5 to reduce the volume of the waste chips.

[0032] When in use, the first rotating rod 44 is driven to rotate by the second motor 45, and the second rotating rod 43 is driven to rotate at the same time under the action of the conveyor belt 46. At this time, the conveyor belt 46 is continuously conveyed, so that the carton is conveyed to the bottom of the cutting knife 311 for cutting. After the cutting is completed, the threaded rod 62 is driven to rotate by the first motor 61. The rotation of the threaded rod 62 drives the first connecting plate 63 and the fixed plate 64 to move, thereby driving the first mounting plate 65, the second mounting plate 66 and the first cleaning brush 67 to move. The first cleaning brush 67 moves along the outer surface of the cutting knife 311 to clean the outer surface of the cutting knife 311. When the threaded rod 62 rotates to drive the first connecting plate 63 and the fixed plate 64 to move, the second cleaning brush 641 moves along the top of the conveyor belt 46 to clean the debris at the top of the conveyor belt 46. The waste collecting box 5 is used to collect waste chips. The waste collecting box 5 is fixed to the support plate 1 by the locking bolt 511. Removing the locking bolt 511 makes it easy to separate the waste collecting box 5 and the support plate 1, thereby facilitating the disposal of waste chips inside the waste collecting box 5.
