[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model discloses a cardboard cutting device. Figure 1-3 A cardboard cutting device comprises a processing table 1, a U-shaped plate 2 is arranged at the upper end of the processing table 1, a plurality of symmetrically distributed mounting blocks 3 are arranged at the upper end of the U-shaped plate 2, a cutting mechanism 4 is arranged on the U-shaped plate 2 for cutting cardboard, and protective mechanisms 5 are arranged on both the front and rear sides of the U-shaped plate 2 for shielding the cutting mechanism 4;

[0025] Reference Figure 2 The cutting mechanism 4 includes two electric push rods 401 and a cutting blade 402. The two electric push rods 401 are symmetrically arranged on the left and right sides of the upper end of the U-shaped plate 2, and the cutting blade 402 is arranged at the bottom ends of the two electric push rods 401; a cutting groove 7 is opened at the upper end of the processing table 1, and the cutting blade 402 is located directly above the cutting groove 7.

[0026] By adopting the above technical solution, after placing the cardboard on the processing table 1, the electric push rod 401 can drive the cutting blade 402 to move downward, and the cutting blade 402 can cut the cardboard by cooperating with the cutting groove 7.

[0027] Reference Figure 3 The protection mechanism 5 includes two connecting rods 501, two blocks 502, a protection plate 503 and two springs 504. The two connecting rods 501 are respectively inserted and arranged on the corresponding mounting blocks 3. The two blocks 502 are respectively arranged at the upper ends of the corresponding connecting rods 501. The protection plate 503 is arranged at the bottom ends of the two connecting rods 501. The lower ends of the front and rear sides of the protection plate 503 are inclined. The bottom end of the protection plate 503 is arc-shaped, and the protection plate 503 is made of transparent material for shielding the cutting blade 402. The two springs 504 are respectively sleeved on the outer sides of the corresponding connecting rods 501. The two ends of the spring 504 are respectively connected to the mounting blocks 3 and the block 502 for resetting the protection plate 503 after moving.

[0028] By adopting the above technical solution, when cutting the cardboard, the cardboard is moved to the lower end of the two protective plates 503, and the protective plates 503 can squeeze the cardboard through the elastic force of the spring 504, so that the cardboard can be positioned, making it difficult for the cardboard to shift during cutting, and the protective plates 503 prevent the staff from contacting the cutting blade 402 during the cutting process, thereby greatly improving the safety of cardboard cutting.

[0029] Reference Figure 2 The rear side of the processing table 1 is sloped, and two symmetrically distributed guide plates 6 are provided on the rear side of the upper end of the processing table 1.

[0030] By adopting the above technical solution, after the cardboard is cut once, the cardboard is continuously pushed to move for the next cutting. At this time, the cut cardboard can be pushed to the rear side of the processing table 1. Since the rear side of the processing table 1 is sloped, the cut cardboard can be automatically unloaded, and the guide plate 6 prevents the cardboard from sliding off the processing table 1.

[0031] Working principle: When the utility model is in use, the electrical components appearing in the present application are all externally connected to the power supply and the control switch. When the cardboard is cut, the cardboard is placed on the upper end of the processing table 1, and then the cardboard is pushed to move on the upper end of the processing table 1. When the cardboard contacts the corresponding protective plate 503, the protective plate 503 will be pushed to move up, and then the cardboard continues to move along the inner side of the U-shaped plate 2. When the cardboard continues to move until it contacts and pushes another protective plate 503 to move up, the cardboard can be stopped at this time, and then the protective plate 503 can be squeezed on the cardboard by the elastic force of the spring 504, so that the cardboard can be positioned, and then the electric push rod 401 can drive the cutting blade 402 to move down to cut the cardboard. During the cutting process, the staff will not contact the cutting blade 402, thereby greatly improving the safety of the cardboard cutting, and then continue to push the cardboard to move for the next cutting. At this time, the cut cardboard can be pushed to the back side of the processing table 1. Since the back side of the processing table 1 is sloped, the cut cardboard can be automatically unloaded.

[0032] When the utility model is in use, the worker will not come into contact with the cutting blade 402 during the process of cutting the cardboard, which greatly improves the safety of the cardboard cutting and facilitates the automatic unloading of the cut cardboard, which greatly improves the practicability of the device.
