DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 6 A cutting device for carton processing includes two corresponding mounting frames 1, the left and right ends of the mounting frames 1 are rotatably connected with a driving wheel 2 and a driven wheel 3, a conveyor belt 4 is transmission-connected between the driving wheel 2 and the driven wheel 3, and a cutting mechanism 5 is fixedly connected to the top center of the mounting frame 1:

[0024] When the edge of the carton needs to be cut, the operator can place the carton to be processed on the input end of the conveyor belt 4, and drive the conveyor belt 4 to transport the carton backward through the cooperation between the driving wheel 2 and the driven wheel 3, so as to facilitate subsequent cutting of the carton.

[0025] Furthermore, the cutting mechanism 5 includes a fixed plate 501, a mounting seat 503 is provided inside the fixed plate 501, a cutting knife 509 is fixedly connected to the center of the bottom of the mounting seat 503, a dual-axis motor 504 is fixedly connected to the left and right sides of the top of the mounting seat 503, a screw rod 505 is fixedly connected to the output ends of both sides of the dual-axis motor 504, a threaded sleeve 506 is threadedly connected to the surface of the screw rod 505, and a pressure wheel mechanism 508 is provided at the bottom of the threaded sleeve 506.

[0026] When the carton to be processed follows the conveyor belt 4 and moves to the bottom of the cutting mechanism 5, the operator starts the electric push rod 502 through the controller 11. When the electric push rod 502 moves downward, it drives the mounting seat 503 to move downward. The cutting knife 509 at the bottom of the mounting seat 503 can cut the carton. When the mounting seat 503 moves downward, it drives the abutment wheel 508 to move downward. The abutment wheel 508 can fix the top of the carton, so that the carton is firmly fixed in the preset cutting position. Through uniform pressure distribution, effective support can be formed on the top of the carton to avoid structural damage or irregular cutting of the carton due to excessive local stress at the moment of cutting. The abutment wheel 508 also prevents the carton from shifting due to mechanical vibration or cutting force during the cutting process, ensuring that the cutting edge is neat and accurate, and can ensure the accuracy of the cutting of the carton, so as to improve product quality.

[0027] Since the specifications of the cartons to be processed are different, when cutting cartons of inconsistent sizes, it is necessary to adjust the spacing between the threaded sleeves 506 according to the specifications of the cartons to be processed. The operator can start the dual-axis motor 504. When the dual-axis motor 504 receives the control signal and starts, the output shafts at both ends will rotate according to the set speed and direction. Due to its threaded structure, when the dual-axis motor 504 shaft rotates, the ball nut on the screw rod 505 converts the rotational motion into linear motion. When the screw rod 505 rotates with the output shafts on both sides of the dual-axis motor 504, it drives the threaded sleeves 506 to gradually approach each other along the surface of the screw rod 505 until the spacing between the threaded sleeves 506 is adjusted to a suitable distance, so as to facilitate the adjustment of the spacing of the pressing wheel mechanism 508 to a suitable distance, thereby facilitating the pressing wheel mechanism 508 to fix the tops of cartons of different sizes.

[0028] Furthermore, a base 10 is fixedly connected to the bottom of the mounting frame 1 , a driving motor 6 is fixedly connected to one side of the base 10 , and a first sprocket 7 is fixedly connected to the output end of the driving motor 6 .

[0029] The base 10 is provided as the basic component of the entire device, and its main function is to provide a stable support and fixing point to ensure that the entire device can be firmly placed on a workbench or on the ground to avoid shaking and instability of the device due to external force or vibration.

[0030] Furthermore, one end of the driving wheel 2 extends to the outside of the mounting frame 1 and is fixedly connected to a second sprocket 8 , and a chain 9 is meshedly connected between the first sprocket 7 and the second sprocket 8 .

[0031] The operator can start the driving motor 6. After the driving motor 6 is started, it drives the first sprocket 7 to rotate. When the first sprocket 7 rotates, it drives the second sprocket 8 to rotate synchronously through the engagement of the chain 9. When the second sprocket 8 rotates, it drives the driving wheel 2 to rotate. When the driving wheel 2 rotates, it drives the conveyor belt 4 to rotate continuously inside the mounting frame 1 through the cooperation of the driven wheel 3, ensuring that the conveyor belt 4 can transport the cartons to be processed to the cutting mechanism 5.

[0032] Furthermore, a fixing plate 501 is fixedly connected to the top of the mounting frame 1 , and a controller 11 is fixedly connected to one side of the fixing plate 501 .

[0033] The controller 11 is configured to ensure accurate execution of the cutting action. The cutting accuracy is ensured by precise control of the electric push rod 502, the driving motor 6 and other driving components, thereby improving the quality of the carton. The automatic control of the trimming process can also be achieved. The operator controls the cutting length, angle and speed through preset programs or parameter inputs, thereby reducing manual intervention and improving production efficiency.

[0034] Furthermore, an electric push rod 502 is fixedly connected to the top of the inner wall of the fixed plate 501, a mounting seat 503 is fixedly connected to the movable end of the electric push rod 502, a limiting plate 507 is fixedly connected to the top of the mounting seat 503, and a threaded sleeve 506 is slidably connected to the limiting plate 507.

[0035] Furthermore, the pressure wheel mechanism 508 includes a movable sleeve 5084 connected to the threaded sleeve 506, a spring 5085 arranged in the center of the movable sleeve 5084, and a wheel seat 5082 connected below the movable sleeve 5084, and a roller 5081 is rotatably connected to the center of the wheel seat 5082.

[0036] The movable sleeve 5084 is used to adjust the abutment pressure. The pressure of the wheel body 5081 on the carton is changed by changing the position of the movable sleeve 5084 on the movable rod 5083, to ensure that the carton is not deformed due to excessive compression, and can be effectively fixed to prevent it from moving during the cutting process. The axis of the roller 5081 is parallel to the cutting knife 509, and the lower end of the cutting knife 509 and the lower end of the roller 5081 are located in the same horizontal plane. The roller 5081 serves as a guiding component of the cutting knife 509, ensuring that the cutting knife 509 moves stably along the preset trajectory, preventing deviation and instability during the cutting process, and improving the cutting accuracy.

[0037] Furthermore, a movable rod 5083 is fixedly connected to the top of the wheel seat 5082 , and the top of the movable rod 5083 extends into the inside of the movable sleeve 5084 and is fixedly connected to the spring 5085 .

[0038] The presence of the set spring 5085 can automatically adjust the pressure of the abutment wheel 508 on the carton according to the different thickness or material of the carton. As the movable sleeve 5084 moves up and down, the spring 5085 will expand and contract accordingly to maintain a stable contact pressure, ensuring that the carton remains stable during the cutting process, avoiding the movement of the carton due to insufficient pressure or damage to the carton due to excessive pressure.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
