[0022] According to Figure 1 、 Figure 2 、 Figure 3 、and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the existing cutting device is difficult to adjust according to the usage situation during cutting, which is not conducive to better cutting the carton and reduces the working efficiency of carton cutting. The general idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a carton cutting device for carton production, which includes a base 1. Four support columns 11 are fixedly installed at the upper end of the base 1. The upper ends of the four support columns 11 are fixedly installed with the same support frame 12. A threaded rod 13 is rotatably installed on the support frame 12. A driving motor 14 is fixedly installed at the side end of the support frame 12. Among them, the output shaft of the driving motor 14 is fixedly connected to the rotating shaft of the threaded rod 13. Two sliding frames 2 are slidably installed on the support frame 12. A number of sliding blocks 21 are slidably installed on each of the two sliding frames 2. A cutting knife 22 is fixedly installed at the lower end of each sliding block 21. A gear 23 is rotatably installed at the side end of each sliding block 21. An adjustment knob 24 is fixedly installed on each gear 23. A rack 25 is fixedly installed at the side end of the sliding frame 2. Among them, the two sliding frames 2 are symmetrically installed. Both of the two sliding frames 2 are threadedly installed with the threaded rod 13. The thread directions of the two sliding frames 2 are opposite. Each gear 23 is meshed with the rack 25. Rotate the adjustment knob 24. The adjustment knob 24 drives the gear 23 to rotate under force. Since the gear 23 is meshed with the rack 25, the gear 23 moves on the rack 25 under force. The movement of the gear 23 drives the sliding block 21 to move. The sliding block 21 moves under force to drive the cutting knife 22. When the cutting knife 22 is at the carton cutting contour line, stop rotating the rack 25. Adjust multiple cutting knives 22 in sequence. Then start the driving motor 14. The output shaft of the driving motor 14 rotates to drive the threaded rod 13. The threaded rod 13 rotates threadedly in the sliding frame 2 under force. Since the thread directions of the two sliding frames 2 are opposite, the two sliding frames 2 move relatively under force. The two sliding frames 2 move to drive the cutting knives 22 to cut the cardboard in opposite directions.

[0024] The positions of the four support columns 11 are respectively located at the four corners of the base 1. Among them, the position of the driving motor 14 is located on the side away from the support columns 11. Rotating blocks 15 are rotatably installed at the side ends of the four support columns 11. Among them, the four rotating blocks 15 all face the side of the threaded rod 13. Springs 16 are fixedly installed at the side ends of the four rotating blocks 15. Among them, the four springs 16 are fixedly connected to the corresponding support columns 11. A covering roller 17 is rotatably installed between two rotating blocks 15. Among them, the two covering rollers 17 are symmetrically installed. The positions of the two covering rollers 17 are respectively located on both sides of the sliding frame 2. Place the cardboard to be cut on the base 1. Push the cardboard to the lower part of the covering roller 17. The covering roller 17 drives the rotating block 15 under force. The rotating block 15 rotates under force. The rotating block 15 rotates to squeeze the spring 16. The spring 16 deforms under force. The reaction force of the deformation of the spring 16 acts on the covering roller 17 to limit and fix the cardboard.

[0025] Working principle:

[0026] First step, when the carton cutting device for carton production is in use, place the cardboard on the base 1. The two pressing rollers 17 limit and fix the cardboard. Then, adjust the cutting knife 22 according to the contour of the carton to be cut. Rotate the adjustment knob 24. The adjustment knob 24 drives the gear 23 to rotate under force. Since the gear 23 is meshed with the rack 25, the gear 23 moves on the rack 25 under force. The movement of the gear 23 drives the sliding block 21 to move. The sliding block 21 drives the cutting knife 22 under force. When the cutting knife 22 is at the carton cutting contour line, stop rotating the rack 25. Adjust multiple cutting knives 22 in sequence. Then start the driving motor 14. The output shaft of the driving motor 14 rotates to drive the threaded rod 13. The threaded rod 13 rotates in a threaded manner in the sliding frame 2 under force. Since the threading directions of the two sliding frames 2 are opposite, the two sliding frames 2 move relatively under force. The movement of the two sliding frames 2 drives the cutting knife 22 to cut the cardboard in an opposite direction. By designing the cutting knife 22 of the carton cutting device for carton production to be adjustable and multiple groups of cutting knives 22 can perform relative cutting, during the cutting process, the adjustable cutting knife 22 can adjust its position according to different carton sizes to meet the processing requirements of different-sized cartons. And the simultaneous cutting of multiple groups of cutting knives 22 effectively improves the working efficiency of carton processing.

[0027] Second step, when the carton cutting device for carton production is in use, place the cardboard to be cut on the base 1. Push the cardboard to the lower part of the pressing roller 17. The pressing roller 17 drives the rotating block 15 under force. The rotating block 15 rotates under force. The rotating block 15 rotates to squeeze the spring 16. The spring 16 deforms under force. The reaction force of the deformation of the spring 16 acts on the pressing roller 17 to limit and fix the cardboard. By installing the pressing roller 17 on the carton cutting device for carton production, during the process of placing the cardboard to be cut, the two pressing rollers 17 can automatically limit and fix the cardboard, thus effectively improving the practicability of the device.

[0028] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
