[0016] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0017] like Figure 1 As shown,

[0018] A carton trimming device, characterized in that it includes a frame 2, a first conveyor belt 3 is provided on one side of the frame 2, a second conveyor belt 4 is provided on the other side of the frame 2, a rotating roller 5 is rotatably connected to the frame 2, the rotating roller 5 is located between the first conveyor belt 3 and the second conveyor belt 4, a double push rod motor 6 is fixedly connected to the frame 2 above the rotating roller 5, a first push rod motor 7 is fixedly connected to the push rod of the double push rod motor 6, a lifting frame 8 is fixedly connected to the push rod of the first push rod motor 7, a lifting frame 8 is rotatably connected to one side of the lifting frame 8 close to the first conveyor belt 3 with two symmetrical pressure wheels 9, a cutting assembly is provided on the side of the lifting frame 8 close to the second conveyor belt 4, and a limiting assembly is provided on the first conveyor belt 3.

[0019] In this embodiment, according to the thickness of the carton board that needs to be trimmed, the first push rod motor 7 drives the lifting frame 8 to move up and down, adjusts the spacing between the pressure wheel 9 and the rotating roller 5, and according to the width of the carton board that needs to be trimmed and the trimming position, the double push rod motor 6 drives the first push rod motor 7 to move to the middle or both sides, adjusts the position of the cutting assembly, and places the carton board that needs to be trimmed on the first conveyor belt 3. The first conveyor belt 3 conveys the carton board forward. The carton board conveyed forward passes through the rotating roller 5 and the pressure roller and contacts the cutting assembly. The cutting assembly cuts off excess burrs, and the trimmed carton board is conveyed forward by the second conveyor belt 4. When the carton board is conveyed forward, the limit assembly limits the left and right sides of the carton board to prevent it from moving left and right and affecting the cutting accuracy. The carton board is assisted by the rotating roller 5 and the pressure roller to prevent the carton board from bending downward due to the action of the downward cutting force during cutting. The first push rod motor 7 and the lifting frame 8 are driven by the double push rod motor 6 to move to the middle or both sides, which is convenient for adjusting the trimming length.

[0020] In this embodiment, the limiting assembly includes two second push rod motors 10, which are symmetrically arranged on the first conveyor belt 3, and the push rods of the second push rod motors 10 are fixedly connected with limiting plates 11. According to the width of the carton board to be cut, the distance of the limiting plates 11 is adjusted by the second push rod motor 10. During the conveying and cutting process of the carton board, both sides of the carton board are limited by the limiting plates 11 to prevent it from moving left and right.

[0021] In this embodiment, the cutting assembly includes two cutting wheels 12, which are rotatably connected to the lifting frame 8. The lifting frame 8 is provided with a driving motor 13 for driving the cutting wheels 12. The driving motor 13 drives the cutting wheels 12 to rotate, thereby trimming the carton board.

[0022] In this embodiment, a collecting rack 14 is provided on the frame 2, and a baffle 15 is fixedly connected to the collecting rack 14. The trimmed carton board is sent to the collecting rack 14 through the second conveyor belt 4 to achieve automatic collection.

[0023] In this embodiment, a collecting box 16 is provided at the lower end of the frame 2. The waste generated by trimming is collected through the collecting box 16.

[0024] In this embodiment, the double push rod motor 6 is provided with a scale 17. The double push rod motor 6 is provided with a scale 17 to facilitate confirmation of the adjustment position of the cutting wheel 12.

[0025] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
