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.

[0021] In order to solve the problem that during the cutting process of existing carton cardboard positioning and cutting equipment, the cut and separated materials require subsequent material pushing to complete collection, and the cut materials will be retained on one side of the blade without subsequent pushing, affecting the removal of the cut materials, this embodiment provides the following technical solutions:

[0022] A cardboard cutting structure for carton processing includes a shell 1, a fixed plate 2 for support is provided at the middle position of the upper end of the shell 1, and the fixed plate 2 is welded and fixed to the shell 1. Figure 1 and Figure 2 As shown, a blade 11 for cutting is horizontally provided in the middle position of the fixed plate 2, and a telescopic rod 10 is provided at both ends of the blade 11, and one end of the telescopic rod 10 is welded and fixed to the blade 11 through a transmission bar 12. The horizontal position of the blade 11 can be directly adjusted by extending and retracting the telescopic rod 10, and cutting can be directly achieved by adjusting the horizontal position of the blade 11;

[0023] In this embodiment, a sliding piece 4 is provided on both sides of the blade 11 in a mirror image, and a sliding rail 5 is provided at both the front and rear ends of the shell 1. A sliding block 6 is provided inside the sliding rail 5, and the sliding block 6 is welded and fixed to the sliding piece 4 at the upper end. The sliding block 6 slides laterally in the sliding rail 5 to adjust the position of the sliding piece 4. The lateral movement of the sliding piece 4 can adjust the spacing between the two sliding pieces 4. The adjustment of the spacing can adapt to the length of the carton shell, and adapt to the length of different carton shells, such as Figure 3 As shown, a threaded rod 14 is provided inside the sliding block 6, and the outer portion of the threaded rod 14 cooperates with the internal thread of the sliding block 6. The rotation of the threaded rod 14 and the restriction of the sliding rail 5 can convert the sliding block 6 from rotational motion to lateral linear motion.

[0024] In this embodiment, an adjustment handle 3 is provided at one end of the threaded rod 14, and the adjustment handle 3 is welded and fixed to the threaded rod 14. Figure 3 As shown, the rotation of the adjustment handle 3 can directly drive the threaded rod 14 to rotate, and the protruding adjustment handle 3 can facilitate the rotation of the threaded rod 14, thereby facilitating the adjustment of the lateral position of the sliding block 6 and the sliding sheet 4;

[0025] In this embodiment, rotatable transmission discs 17 are provided on both sides of the sliding plate 4 facing the fixed plate 2, and the outer sides of the two transmission discs 17 are connected by a transmission belt 15. Figure 4 As shown, the transmission disc 17 and the sliding plate 4 are rotatably connected via a connecting shaft 8, wherein a motor 9 is provided at one end of the connecting shaft 8, and the transmission belt 15 can be driven by the output of the motor 9;

[0026] In this embodiment, a pressing block 16 is evenly arranged around the front end of the transmission belt 15. The pressing block 16 can be driven to move laterally through the output of the transmission disc 17 and the transmission of the transmission belt 15. Figure 3 and Figure 4 As shown, the extended pressing block 16 can press the cutting material while pushing the cutting material, actively driving the cutting material to move laterally;

[0027] In this embodiment, the lower end of the outer portion of the pressing block 16 is provided with a protective sheet 20 by gluing. During the transmission of the pressing block 16, Figure 5 As shown, the pressing block 16 can avoid the low friction coefficient affecting the stability of the carton shell push through the connected protective sheet 20;

[0028] In this embodiment, upper movable cavities 18 are uniformly distributed laterally on the lower end of the interior of the sliding sheet 4, and a strip-shaped lower movable cavity 19 is provided at the lower end of the upper movable cavity 18. Figure 1 、 Figure 3 and Figure 4 As shown, the upper movable cavity 18 and the lower movable cavity 19 both pass through and extend to the front and rear ends of the sliding sheet 4, and a protective sheet 20 is laterally arranged at the upper end of the sliding rail 5, and the outer portion of the protective sheet 20 is connected to the internal sliding slot of the lower movable cavity 19. When the sliding block 6 slides laterally in the sliding rail 5, the sliding sheet 4 will slide laterally in the protective sheet 20, and the lateral sliding will improve the stability of the sliding sheet 4. The upper end of the interior of the protective sheet 20 is laterally provided with a transmission roller 7 in sequence. The transmission roller 7 is located inside the upper movable cavity 18, and one end of the transmission roller 7 is rotatably connected to the inner wall of the shell 1. When the sliding sheet 4 moves laterally at the upper end of the fixed plate 2, the transmission roller 7 will slide laterally in the upper movable cavity 18 to avoid affecting the protruding transmission roller 7 during the lateral movement of the sliding sheet 4, and to avoid the carton sheet to be cut from being unable to contact the rotatable transmission roller 7;

[0029] In this embodiment, a recessed cavity 13 is provided at the lower end of the outer portion of the blade 11, and the recessed cavity 13 is recessed inside the housing 1, as shown in FIG. Figure 2 As shown, the concave cavity 13 facilitates the cutting of the blade 11, and facilitates the blade 11 to completely cut the carton shell, avoiding collision between the shell 1 and the blade 11 during cutting.

[0030] Working principle: When using the device and cutting the carton processing material, the threaded rods 14 on both sides of the fixed plate 2 are rotated according to the size of the carton material. The rotation of the threaded rods 14 can produce relative movement with the inside of the sliding block 6. After the sliding block 6 is restricted by the sliding rail 5, the sliding block 6 can be converted from rotational motion to lateral linear motion, so that the sliding block 6 can move laterally in the sliding rail 5. The pressing position of the pressing block 16 is directly adjusted, and the carton shell is placed on the upper end of the transmission roller 7. After placing the upper end of the transmission roller 7, the pressing block 16 will press on the upper end of the carton shell. The carton shell is fixed by pressing. At the same time, the motor can drive the transmission disc 17 to rotate through the connecting shaft 8. The rotation of the transmission disc 17 can drive the transmission belt 15 for transmission, and the transmission of the transmission belt 15 can The externally connected pressing block 16 for pressing and fixing is driven to move. During the movement of the pressing block 16, the carton is driven to move laterally, so that the carton shell passes through the blade 11. After the cutting position of the carton shell overlaps with the position of the blade 11, the telescopic rod 10 is started. The contraction of the telescopic rod 10 can drive the blade 11 to move toward the carton shell through the transmission bar 12. As the telescopic rod 10 continues to contract, the blade 11 can complete the cutting. The materials on both sides of the blade 11 will contact the pressing block 16. Subsequently, the pressing block 16 can drive the material to move laterally actively through the rotation of the transmission disk 17, avoiding manual pushing of the material to be cut and the lateral movement of the cut material, and avoiding the cut material from being retained on one side of the blade without subsequent pushing.
