[0024] The following describes in detail, with reference to the accompanying drawings, a cutting machine for paper box production according to an embodiment of the present invention.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4An embodiment of a paper box production cutting machine provided by this utility model includes a frame 1. A front electric conveyor roller group 2 and a rear electric conveyor roller group 3 are fixedly installed on the top of the frame 1. A knife holder 4 is fixedly installed between the front electric conveyor roller group 2 and the rear electric conveyor roller group 3. A cutting table 7 is fixedly installed on the inner side of the bottom of the knife holder 4. A hydraulic cylinder 5 is fixedly installed on the top of the knife holder 4. A cutting blade 6 is slidably connected to the inner side of the knife holder 4. The output end of the hydraulic cylinder 5 is fixedly installed on the top of the cutting blade 6. A first limiting component is provided on the top of the front electric conveyor roller group 2. A second limiting component is provided on the inner side of the rear electric conveyor roller group 3. A cardboard 10 to be processed is provided on the top of the front electric conveyor roller group 2 and the rear electric conveyor roller group 3.

[0027] The second limiting assembly includes a first slide rod 801, a first adjusting screw 802, a fixing frame 803, a first limiting plate 804, an adjusting rod 805, a bracket 806, an electric telescopic rod 807, and a first drive motor 808. The first slide rod 801 is fixedly installed inside the rear electric conveying roller group 3. The first adjusting screw 802 is rotatably connected to the inner side of the rear electric conveying roller group 3. One end of the fixing frame 803 is slidably connected to the outer wall of the first slide rod 801, and the other end of the fixing frame 803 is movably installed on the outer wall of the first adjusting screw 802. The bottom of the first limiting plate 804 is rotatably connected to the inner side of the fixing frame 803. One end of the adjusting rod 805 is fixedly connected to the outer side of the rotating shaft of the first limiting plate 804. The wall, one end of the bracket 806 is fixedly connected to one side of the bracket 806, the electric telescopic rod 807 is movably installed inside the bracket 806, the first drive motor 808 is fixedly installed at one end of the rear electric conveyor roller group 3, the first adjusting screw 802 is threadedly engaged with one end of the fixed frame 803, one end of the first adjusting screw 802 is fixedly installed at one end of the output shaft of the first drive motor 808, the first limiting plate 804 is located at the front end of the paperboard 10 to be processed, and one side surface of the first limiting plate 804 abuts against one end of the paperboard 10 to be processed, one end of the electric telescopic rod 807 is rotatably connected to one end of the adjusting rod 805, and the other end of the electric telescopic rod 807 is rotatably connected to the inside of one end of the bracket 806.

[0028] It should be noted that by setting a fixed frame 803 that can move back and forth on the first slide bar 801 and a flip-up first limiting plate 804, the first drive motor 808 drives the first adjusting screw 802 to adjust the front and rear position of the fixed frame 803. By setting an electric telescopic rod 807 to push or pull the adjusting rod 805, the first limiting plate 804 can be unfolded and flipped. In use, according to the required length of the cardboard to be cut, the first drive motor 808 drives the first adjusting screw 802 to adjust the position of the fixed frame 803, and through the cooperation of the electric telescopic rod 807 and the adjusting rod 805, the first limiting plate 804 is unfolded and erected. When the cardboard is conveyed by the front electric conveying roller group 2 and the rear electric conveying roller group 3, the front end of the cardboard abuts against one side of the first limiting plate 804, which can accurately position the required length of the cardboard to be cut, which is convenient to use, improves the consistency of cardboard material cutting, and ensures the quality of subsequent cardboard box production. The unfolding angle of the first limiting plate 804 is 90 degrees, which is perpendicular to the upper surface of the frame 1.

[0029] Example 2

[0030] In some embodiments, such as Figure 1 , Figure 2 As shown, the first limiting assembly includes two second slide rods 901, a second adjusting screw 902, a second drive motor 903, and a second limiting plate 904. The two second slide rods 901 are respectively fixedly installed on the inner sides of both ends of the front electric conveying roller group 2. The second adjusting screw 902 is rotatably connected to the inner side of the middle part of the front electric conveying roller group 2. The second drive motor 903 is fixedly installed on one side of the front electric conveying roller group 2. The bottom of the second limiting plate 904 is slidably connected to the outer wall of the second slide rods 901. The second adjusting screw 902 is rotatably connected to the outer wall of the second limiting plate 904, and the second adjusting screw 902 and the second limiting plate 904 are threadedly engaged. The inner surface of the second limiting plate 904 abuts against the two edges of the cardboard 10 to be processed.

[0031] It should be noted that by setting two second limiting plates 904, the inner surfaces of the two second limiting plates 904 abut against both sides of the paperboard 10 to be processed, which can limit the paperboard 10 to be processed and prevent it from shifting during the transmission process. The second driving motor 903 drives the second adjusting screw 902 to rotate and engage with the two second limiting plates 904. The position of the second limiting plates 904 can be adjusted according to the width of the paperboard.

[0032] Working principle: In use, based on the required length and width of the cardboard to be cut for cardboard production, the first drive motor 808 drives the first adjusting screw 802 to engage with the fixed frame 803, adjusting the position of the fixed frame 803. Then, the second drive motor 903 drives the second adjusting screw 902 to rotate, engaging with the two second limiting plates 904, adjusting the position of the second limiting plates 904. The front electric conveyor roller group 2 and the rear electric conveyor roller group 3 are used to convey the cardboard 10 to be processed. At the same time, the two second limiting plates 904 limit the sides of the cardboard 10 to be processed. Furthermore, the electrical... The telescopic rod 807 and the adjusting rod 805 work together to unfold and erect the first limiting plate 804. When the cardboard is conveyed by the front electric conveying roller group 2 and the rear electric conveying roller group 3, the front end of the cardboard abuts against one side of the first limiting plate 804, which can accurately position the length of the cardboard to be cut. After the hydraulic cylinder 5 drives the cutting blade 6 to cut the cardboard, the telescopic rod 807 and the adjusting rod 805 work together to retract the first limiting plate 804. At the same time, the rear electric conveying roller group 3 is used to convey the cut cardboard out to wait for the next step of cardboard box processing. It can continuously cut and accurately position and cut the cardboard 10 to be processed.

[0033] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
