[0002] A cardboard cutting machine is a mechanical device specially used for cutting cardboard. It is widely used in express delivery, logistics, packaging, printing and other industries. Its product structure includes a cutting mechanism, a conveying mechanism, a positioning mechanism and other parts. The working principle is to transport the cardboard to the position of the cutting mechanism through the conveying mechanism, and the cutting mechanism performs cutting. At the same time, the positioning mechanism ensures the accuracy and correctness of the cutting. The advantages of a cardboard cutting machine are fast and accurate cutting, a high degree of automation, reduced manual operation costs, and high cutting accuracy and stability.
[0003] However, the existing cutting machine does not have a structure to correct the deviation of the cardboard during transportation, so the cardboard will experience different degrees of lateral shaking during the operation of the conveying device, causing the cardboard to deflect and swing, resulting in most of the cardboard and the cutter to be cut in a straight line, thereby failing to ensure the accuracy of the cardboard cutting, thereby reducing the cutting quality of the cardboard. Therefore, this application proposes another technical solution to solve the above problem. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the utility model provides a cardboard cutting machine with a correction component, which has the advantages of conveniently correcting the cardboard during transportation. It solves the problem that there is no structure for correcting the cardboard during transportation, which causes the cardboard to shake to varying degrees during the operation of the conveying device, causing the cardboard to deflect and swing, resulting in most of the cardboard being cut in a straight line with the cutter.

[0019] 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.
[0020] See also Figures 1 to 3 In this embodiment, a cardboard cutting machine with a correction component includes a fixed base 1, and an alignment adjustment mechanism is provided inside and on the top of the fixed base 1.
[0021] In this embodiment, the alignment adjustment mechanism includes a stepper motor 2 fixedly installed on the left side of the fixed base 1, and the output shaft of the stepper motor 2 is fixedly installed with a bidirectional screw 3 that is rotatably connected to the fixed base 1. A bearing groove is provided on the left side of the fixed base 1, and the bidirectional screw 3 is rotatably connected to the fixed base 1 through the bearing groove, which facilitates the stepper motor 2 to drive the bidirectional screw 3 to rotate.
[0022] Among them, the outer side of the bidirectional screw 3 is threadedly connected to two threaded blocks 4, and the outer side of the bidirectional screw 3 is provided with two threaded grooves in opposite directions. The two threaded blocks 4 are threadedly connected to the bidirectional screw 3 through corresponding threaded grooves, which helps the two threaded blocks 4 to move closer to or away from each other. A limiting rod 5 that is slidably connected to the fixed base 1 is fixedly installed on the top of the threaded block 4.
[0023] In this embodiment, a limiting groove is provided on the top of the fixed base 1, and the limiting rod 5 is slidably connected to the fixed base 1 through the limiting groove, which helps the limiting rod 5 to limit the threaded block 4. A flat plate 6 is fixedly installed on the top of the limiting rod 5, and a fixed frame 7 is fixedly installed on the top of the fixed base 1. A plurality of conveying rollers 8 are fixedly installed on the inner side of the fixed frame 7. The top of the conveying roller 8 is movably connected to the cardboard body 9, and a cutting component is provided on the inner side of the fixed frame 7.
[0024] Among them, the cutting assembly includes a hydraulic cylinder 10 fixedly installed on the inner top wall of the fixed frame 7, the output shaft of the hydraulic cylinder 10 is fixedly installed with a mounting plate 11, and fixed shafts 12 are fixedly installed on the left and right inner walls of the fixed frame 7. The outer side of the fixed shaft 12 is movably connected with a buffer spring 13, and the top of the buffer spring 13 is fixedly installed with a slider 14 fixedly connected to the mounting plate 11.
[0025] In this embodiment, a sliding groove is opened inside the slider 14, and the slider 14 is slidably connected to the fixed shaft 12 through the sliding groove, which helps the slider 14 move and limit the mounting plate 11. A cutting knife 15 is fixedly installed at the bottom of the mounting plate 11.
[0026] It should be noted that the cardboard cutting machine with a correction component, through the set alignment adjustment mechanism, uses the action of the stepping motor 2 and the bidirectional screw 3 to drive the limit rod 5 and the flattening plate 6 to move until the two flattening plates 6 move in contact with the cardboard body 9, thereby correcting the cardboard body 9 and placing it crooked. Under the action of the two flattening plates 6, the cardboard body 9 is centered and not skewed, which helps to center flattening plates 6 of different sizes. At the same time, the hydraulic cylinder 10, the mounting plate 11, the slider 14 and the fixed shaft 12 can drive the cutting knife 15 to move vertically downward to cut the cardboard body 9. At the same time, the buffer spring 13 can provide a certain buffer to avoid excessive cutting force, thereby greatly improving the cutting flatness and accuracy of the device.
[0027] The working principle of the above embodiment is:
[0028] When using the cardboard cutting machine with a correction component, the cardboard body 9 can first be placed on the top of the conveying roller 8, and then the conveying roller 8 can be started to convey the cardboard body 9. At this time, the stepping motor 2 can be started, and the stepping motor 2 drives the bidirectional screw 3 to rotate. The two threaded blocks 4 on the outer sides of the bidirectional screw 3 begin to move closer to each other. The movement of the threaded block 4 drives the limit rod 5 and the leveling plate 6 to move until the two leveling plates 6 move in contact with the cardboard body 9, thereby correcting the cardboard body 9 and preventing it from being skewed. Under the action of the two leveling plates 6, the cardboard body 9 is centered and aligned without being skewed, which helps to center and align leveling plates 6 of different sizes, thereby improving the flexibility of correction.
[0029] During the conveying process of the cardboard body 9, the hydraulic cylinder 10 can be started, and the hydraulic cylinder 10 drives the mounting plate 11 to move downward. The sliders 14 on the left and right sides of the mounting plate 11 move downward smoothly under the limit of the fixed shaft 12, and make the mounting plate 11 and the cutting knife 15 move vertically downward. At the same time, the buffer spring 13 is compressed during the movement of the slider 14 until the cutting knife 15 cuts the cardboard body 9, avoiding excessive cutting force, greatly improving the cutting flatness and accuracy of the device, and increasing the practicality of the device.
