[0023] The utility model provides a technical solution: Figure 1-Figure 4As shown, in the present embodiment, a corrugated cardboard cutting device comprises a mounting frame 1, a conveyor belt 8 is arranged inside the mounting frame 1, a fixed plate 9 is fixedly connected to the outer side of the mounting frame 1, two first vertical plates 3 are fixedly connected to the top of the fixed plate 9, a displacement assembly is arranged between the two first vertical plates 3, a displacement frame 5 is slidably connected to the top of the fixed plate 9, a guide rod 13 is slidably connected inside the displacement frame 5, a displacement plate 12 is fixedly connected to the bottom of the guide rod 13, a first cylinder 2 is fixedly installed on the top of the displacement frame 5, one end of the movable rod of the first cylinder 2 is fixedly connected to the top of the displacement plate 12, a cutting assembly is arranged inside the displacement plate 12, a cutting mechanism 22 is fixedly installed on the bottom of the cutting assembly, a mounting plate 6 is fixedly connected to the top of the mounting frame 1, and a guide assembly is arranged on one side of the mounting plate 6.

[0024] First, place the cardboard on the top of the conveyor belt 8, then start the conveyor belt 8 to drive the cardboard to move. The operating principle of the conveyor belt 8 is an existing mature technology and will not be repeated here. When the cardboard moves on the conveyor belt 8, the guide components set on both sides of the mounting frame 1 can limit the outer side of the cardboard, so that it is smoother when moving, and there will be no offset problem when cutting, thereby ensuring the neatness of cutting, thereby increasing the stability of the cardboard during cutting, and then starting the displacement component to better perform the cutting operation on any position of the cardboard, and the displacement component drives the cutting mechanism 22 inside the displacement frame 5 to move with the moving frequency of the conveyor belt 8, thereby also making the paper The plate can perform multiple cutting operations without stopping, thereby increasing the cutting efficiency of the device. Then, when cutting, by starting the cutting component, the cutting mechanism 22 can be driven to move more smoothly during cutting, so that there will be no problem of cutting offset, thereby increasing the stability of the device. Finally, by starting the first cylinder 2, the movable rod is moved to drive the displacement plate 12 to move downward, and the movement of the displacement plate 12 is guided by the guide rod 13. Then the displacement plate 12 moves downward and drives the cutting mechanism 22 to approach the top of the cardboard, so that the cardboard is cut by starting the cutting mechanism 22. The cutting mechanism 22 is a mature existing technology and will not be described in detail here.

[0025] like Figure 1-Figure 4 As shown, the displacement assembly includes a reciprocating screw 4, which is rotatably connected between two first vertical plates 3, wherein a motor 7 is fixedly installed on one side of one of the first vertical plates 3, and one end of the output shaft of the motor 7 is fixedly connected to one end of the reciprocating screw 4, and a threaded groove is opened inside one side of the displacement frame 5 and is threadedly connected to the outer side of the reciprocating screw 4. The displacement assembly also includes two second vertical plates 10, and the two second vertical plates 10 are fixedly connected to the top of the fixed plate 9, and a sliding rod 11 is fixedly connected between the two second vertical plates 10, and the side of the displacement frame 5 away from the reciprocating screw 4 is movably sleeved with the outer side of the sliding rod 11.

When the displacement frame 5 moves, the cutting mechanism 22 is driven to move, so as to perform cutting operations on different positions of the cardboard.

[0027] like Figure 1-Figure 4 As shown, the guide assembly includes a displacement rod 19, which is slidably connected to the inside of the mounting plate 6, one end of the displacement rod 19 is fixedly connected to an L-shaped plate 16, and the inside of the L-shaped plate 16 is equidistantly connected to a guide wheel 15 for rotation. The guide assembly also includes a limit plate 18, which is fixedly connected to one end of the displacement rod 19, and a spring 17 is fixedly connected between one side of the limit plate 18 and the mounting plate 6.

[0028] When the cardboard moves, the outer side of the cardboard contacts the outer side of the guide wheel 15, so that the cardboard moves more smoothly under the action of the guide wheel 15, and then the cardboard contacts the guide wheel 15, thereby driving the displacement rod 19 to slide inside the mounting plate 6 and stretching the spring 17, and then the guide wheel 15 is driven to contact the outer side of the cardboard under the reaction force of the spring 17, thereby limiting the position of the cardboard, thereby increasing the stability of the cardboard during cutting.

One end of the movable rod of the second cylinder 24 is fixedly connected to one side of the displacement block 14, and the top of the displacement block 14 is fixedly connected to the limit block 21, and the bottom of the limit block 21 is slidably connected to the top of the displacement plate 12.

[0030] When performing horizontal cutting, the movable rod of the second cylinder 24 is started to move the displacement block 14 to slide inside the limit groove 20 and drive the cutting mechanism 22 to perform a moving cutting operation. When the displacement block 14 moves, it drives the limit block 21 to move on the top of the displacement plate 12, and then cooperates with the limit groove 20 to make the cutting mechanism 22 more stable when moving.

[0031] The utility model provides a cutting device for corrugated cardboard, and the specific working principle is as follows: first, the cardboard is placed on the top of the conveyor belt 8, and then the conveyor belt 8 is started to drive the cardboard to move, and then the outer side of the cardboard contacts the outer side of the guide wheel 15, so that the cardboard moves more smoothly under the action of the guide wheel 15, and then the cardboard contacts the guide wheel 15, so as to drive the displacement rod 19 to slide inside the mounting plate 6 and stretch the spring 17, and then the guide wheel 15 is driven to contact the outer side of the cardboard under the reaction force of the spring 17, so as to limit the position of the cardboard, thereby increasing the stability of the cardboard during cutting, and then, by starting the output shaft of the motor 7 to rotate, the reciprocating screw rod 4 is driven to rotate and the two sides of the displacement frame 5 are respectively moved on the outer sides of the reciprocating screw rod 4 and the slide rod 11, and then the slide rod 1 1 guides the movement of the displacement frame 5 to avoid deviation during movement. When the displacement frame 5 moves, the cutting mechanism 22 is driven to move, so as to perform cutting operations on different positions of the cardboard. Then, the movable rod of the first cylinder 2 is started to move to drive the displacement plate 12 to move downward, and the movement of the displacement plate 12 is guided by the guide rod 13. Then, the displacement plate 12 moves downward to drive the cutting mechanism 22 to approach the top of the cardboard, so as to cut the cardboard by starting the cutting mechanism 22. At the same time, by starting the second cylinder 24, the movable rod is moved to drive the displacement block 14 to slide inside the limiting groove 20 and drive the cutting mechanism 22 to perform a moving cutting operation. When the displacement block 14 moves, the limiting block 21 is driven to move on the top of the displacement plate 12, and then the limiting groove 20 is cooperated to make the cutting mechanism 22 more stable when moving.
