[0018] 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.

[0019] Specific implementation cases:

[0020] like Figure 1 As shown, a cutting device for cardboard processing includes a bracket 1, characterized in that: a conveyor belt 2 is installed on the bracket 1, the conveyor belt 2 is driven by a motor, a first clamping mechanism 3 is installed on the bracket 1, a trimming mechanism 4 is installed on the bracket 1, a second clamping mechanism 5 is installed on the bracket 1, and a cutting mechanism 6 is installed on the bracket 1. The right side of the first clamping mechanism 3 is the trimming mechanism 4, the right side of the trimming mechanism 4 is the second clamping mechanism 5, and the right side of the second clamping mechanism 5 is the cutting mechanism 6. When working, the cardboard enters the first clamping mechanism 3 from the conveyor belt 2 for clamping, and enters the trimming mechanism 4 as the conveyor belt 2 moves. The trimming mechanism 4 removes the excess material on the side of the cardboard and determines the width of the cardboard. Then the cardboard enters the second clamping mechanism 5 for secondary clamping of the cardboard, and enters the cutting mechanism 6 after clamping. The cutting mechanism 6 can only cut cardboard of a certain size. After cutting, the conveyor belt 2 sends it out of the device.

[0021] like Figure 2 As shown, a spring (not marked in the figure) is installed on the first pressing mechanism 3, a spring (not marked in the figure) is installed on the second pressing mechanism 5, a trimming knife 42 is installed at the lower end of the trimming mechanism 4, the direction of the edge of the trimming knife 42 is longitudinal, two groups of stacked pressing wheels 41 are installed on both sides of the trimming mechanism 4, a spring (not marked in the figure) is installed above the pressing wheel 41, and the pressing wheel 41 is in conflict with the conveyor belt 2. The springs of the first pressing mechanism 3 and the second pressing mechanism 5 can contract and press the cardboard when the cardboard passes through and contacts the first pressing mechanism 3 and the second pressing mechanism 5. The pressing wheel 41 can press the cardboard when the carton is trimming, so as to prevent the processing quality from being affected by the loose pressing. The longitudinal edge of the trimming knife 42 cuts the side of the cardboard. There are two groups of trimming knives 42, and their relative distance can be adjusted as needed, which is used to cut cardboard of different sizes and widths.

[0022] like Figure 3As shown, the cutting mechanism 6 includes a connecting plate 61, which is characterized in that: a fixed rack 62 is installed on one side of the connecting plate 61, a gear 64 is installed on the connecting plate 61, the gear 64 is meshed with the connecting plate 61, a gear limiting groove 63 is provided on the connecting plate 61, the gear 64 is slidably connected to the gear limiting groove 63, a first connecting rod 65 is rotatably connected to the gear 64, and the other end of the first connecting rod 65 is rotatably connected to the second connecting rod 67, the length of the first connecting rod 65 is greater than the length of the second connecting rod 67, and the second connecting rod 67 is rotatably connected to the first connecting rod 65. The rod 67 is rotatably mounted on the connecting plate 61, and the driving mode of the second connecting rod 67 is motor-driven. The other end of the gear 64 is meshed with a movable rack 68. The connecting plate 61 is provided with a rack limiting groove 66. The movable rack 68 is slidably connected with the rack limiting groove 66. A connecting frame 69 is installed at the lower end of the connecting plate 61, and a cutting knife 70 is installed on the connecting frame 69. The direction of the cutting edge of the cutting knife 70 is horizontal and the length of the cutting knife 70 is greater than the width of the conveyor belt 2. The bracket 1 and the conveyor belt 2 are all provided with knife grooves 71 at the corresponding positions of the cutting knife 70. When the work starts, the motor connected to the second connecting rod 67 is started (not shown in the figure), the second connecting rod 67 starts to rotate, and the first connecting rod 65 connected to the second connecting rod 67 is driven by it to move at a certain angle. The upper end of the first connecting rod 65 is connected to the gear 64 for rotation. The gear 64 is limited by the gear limiting groove 63 and can only do up and down reciprocating motion. When the first connecting rod 65 moves, it pushes the gear 64 to move in the direction limited by the gear limiting groove 63 and the fixed rack 62. The other end of the gear 64 meshes with the movable rack 68. When the gear 64 moves At the same time, the movable rack 68 is pulled to move in the same direction. The movement range and direction of the movable rack 68 are limited by the rack limiting groove 66. When the motor continues to rotate, the cooperation between the first connecting rod 65 and the second connecting rod 67 and the gear 64 can realize equidistant reciprocating motion. The movable rack 68 is fixedly connected to the connecting frame 69. The movement of the movable rack 68 can drive the cutting knife 70 on the connecting frame 69 to continuously reciprocate up and down. The cutting knife 70 cooperates with the knife groove 71 to cut the cardboard, and the length of the cardboard can be adjusted by adjusting the speed of the motor.

[0023] In summary, by the simultaneous movement of the trimming mechanism 4 and the cutting mechanism 6, it is possible to simultaneously complete the material work on the cardboard raw material during the process of cutting the carton, thereby reducing the time used for production. By means of the first clamping mechanism 3 and the second clamping mechanism 5 and the clamping wheel 41, the cardboard is always in a clamped state during processing, which facilitates the cutting work. By means of the cooperation of the first connecting rod 65 and the second connecting rod 67 with the gear 64, the meshing of the gear 64 and the movable rack 68 realizes equidistant reciprocating motion. The movable rack 68 moves the same distance and direction each time it reciprocates, thereby making the cutting knife 70 cut the same length when cutting the cardboard, greatly improving the cutting accuracy and efficiency. The length of the cardboard can be adjusted by adjusting the speed of the motor, and the width of the cardboard can be adjusted by adjusting the distance between the two trimming knives 42 in the trimming mechanism 4.

[0024] The above is only a preferred implementation of the present application. The protection scope of the present application is not limited to the above embodiments. All technical solutions under this idea belong to the protection scope of the present application. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present application should also be regarded as the protection scope of the present application.
