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.

[0024] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0025] Combine Figure 1 The utility model provides a trimming device for producing packaging boxes, comprising a cutting plate driving mechanism 1, the movable end of the cutting plate driving mechanism 1 is connected to the trimming mechanism 2, and a pressing and fixing mechanism 3 is fixedly arranged on one side of the trimming mechanism 2. The cutting plate driving mechanism 1 includes a processing table 12, the trimming mechanism 2 includes a movable lifting component 25, the output end of the lifting component 25 is connected to a lifting block 26, a knife frame 27 is fixedly inserted into the lifting block 26, an oblique blade 28 is positioned and fixed on one side of the knife frame 27, and an L-shaped block 29 is fixed to one end of the knife frame 27. The pressing and fixing mechanism 3 includes a vertical block 31 fixed to one side of the trimming mechanism 2, and an insertion rod 32 inserted into the vertical block 31. The upper end of the insertion rod 32 is sleeved with a spring 33, and the lower end is connected to a pressing block 35.

[0026] Specifically, the processing table 12 provides an incision for cutting the cardboard, and the lifting component 25 can control the lifting and lowering of the knife frame 27. The oblique blade 28 is fixed by the screw connection of the knife frame 27 and the L-shaped block 29. When the lifting component 25 controls the oblique blade 28 to descend, the knife frames 27 and L-shaped blocks 29 on both sides of the oblique blade 28 will pressurize and fix the pressure block 35 to achieve fixation on both sides of the cutting end of the carton, and as the oblique blade 28 moves in cutting, the position of the knife frame 27 and the L-shaped block 29 relative to the pressure block 35 moves accordingly to ensure the stability of cutting. When the cutting is completed, the oblique blade 28 rises, and at this time the pressure block 35 rises under the elastic action of the spring 33, which will not affect the removal of the carton.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example 1:

[0029] Combine Figure 2-Figure 5The cutting plate driving mechanism 1 also includes a fixed frame bar 11 arranged at the lower end of the processing table 12, a support frame 13 arranged at the four corners of the processing table 12, a guide rod 14 and a driving rod 15 sleeved on both sides of the upper end of the support frame 13, and a driving motor 151 is fixed to one end of the driving rod 15. The support frame 13 and the fixed frame bar 11 are fixed by screws. The guide rod 14 provides a guide for the trimming mechanism 2, and the driving motor 151 drives the driving rod 15 to rotate, thereby driving the trimming mechanism 2 sleeved on the driving rod 15 to move.

[0030] A plurality of cutting grooves 121 are arranged in parallel on the processing table 12, and a plurality of connecting rods 122 are fixed in parallel in the cutting grooves 121. The cutting grooves 121 reserve cutting positions to prevent the processing table 12 from being scratched. The connecting rods 122 reinforce the processing table 12 and improve its service life. The reservation of the cutting grooves 121 also enables the oblique blade 28 to extend downward by a certain distance.

[0031] The trimming mechanism 2 includes a trimming motor 21, a trimming screw 22 arranged at the output end of the trimming motor 21, and side frames 24 are sleeved on both sides of the trimming screw 22. The two groups of side frames 24 are respectively inserted into the guide rod 14 and the drive rod 15. Two groups of sliding rods 23 are connected between the two groups of side frames 24. The trimming motor 21 drives the trimming screw 22 to rotate, and the side frame 24 is arranged at the output end of the drive rod 15 for shifting. The sliding rod 23 provides a sliding guide for the lifting component 25.

[0032] A positioning block 271 is fixed to one side of the tool holder 27, and the lower end of the tool holder 27 is rotatably connected to the first pulley 272. A positioning groove 281 is provided on the bevel blade 28 to align with the positioning block 271, and a screw 282 is fixed in the positioning groove 281.

The second pulley 291 and the first pulley 272 are respectively in rolling contact with the two sides of the pressure block 35. The arrangement of the second pulley 291 and the first pulley 272 respectively reduces the moving friction between the knife frame 27, the L-shaped block 29 and the pressure block 35 when the trimming mechanism 2 is trimming.

[0034] Example 2:

[0035] Combine Figure 4 A lifting groove 311 is provided inside the vertical block 31, and an oblique block 34 is provided through the lifting groove 311. The oblique block 34, the vertical block 31 and the pressing block 35 are fixed to each other. The spring 33 provides elastic force for the vertical block 31. The insertion rod 32, the vertical block 31 and the pressing block 35 form a triangular structure to enhance stability. The lifting groove 311 provides a lifting limit for the insertion rod 32.
