[0019] Referring to Fig. 1 Frame 1 is installed with servo motor 6 on the both sides parallel to the axis of support 201, and the input end of a paperboard conveying line 3 is connected with servo motor 6, and the paperboard conveying line 3 is connected with synchronous transmission mechanism, paperboard conveying line 3 includes a plurality of spline shafts 301 rotatably installed on frame 1, spline outer cylinders 302 are slidably arranged on the middle parts of a plurality of spline shafts 301, and conveying belts 303 are arranged on the spline outer cylinders 302. Support 201 is located above the gap between the two paperboard conveying lines 3, which facilitates trimming roller 202 to pass through the gap and trim the end of paperboard.

[0020] Referring to Fig. 2 Frame 1 is installed with side edge trimming assembly 4 on the both sides parallel to the paperboard conveying line 3, and the side edge trimming assembly 4 includes electric telescopic rod 404 installed on frame 1, and connecting plate 401 is installed on the movable end of electric telescopic rod 404, and connecting plate 401 is driven along X axle through the telescopic drive of electric telescopic rod 404. A plurality of trimming wheels 403 are installed on connecting plate 401, and adjacent two trimming wheels 403 are connected with synchronous transmission mechanism, and one of the trimming wheels 403 is connected with external power input device. The trimming wheel 403 is driven to rotate through the power input device, and the side edge of paperboard is trimmed by the differential speed between the trimming wheel 403 and paperboard.

[0021] Referring to Fig. 3The connecting plate 401 is further provided with two conveyors 402, the rollers of the lower conveyor 402 are respectively sleeved on the corresponding spline shafts 301, and the upper surface of the conveyor 402 is flush with the upper surface of the conveying belt 303. The upper and lower conveyors 402 are drivingly connected through a synchronous transmission mechanism. In the side trimming process, the conveyors 402 on the connecting plate 401 play an auxiliary role, which can better stabilize the position and movement state of the paperboard during trimming.

[0022] The synchronous transmission mechanism can be selected as needed, such as a chain transmission unit or a belt transmission unit with tension adjustment function.

[0023] The connecting plate 401 is further provided with a guide rod 7, the distal end of the guide rod 7 is sleeved through the rack 1, and the guide rod 7 is used for guiding and supporting the connecting plate 401.

[0024] The implementation principle of the carton trimming mechanism in the embodiment of the application is as follows:

[0025] The paperboard is transmitted on the paperboard conveying line 3. The paperboard conveying line 3 is driven by the servo motor 6, the spline shaft 301 rotates and drives the conveying belt 303 to run through the spline outer cylinder 302, and the paperboard is conveyed to the working area of the trimming mechanism.

[0026] When the paperboard enters below the end edge trimming assembly 2, the photoelectric sensors 5 located on both sides of 201 on the rack 1 detect the position of the paperboard.

[0027] If only one group of photoelectric sensors detects the paperboard, it indicates that the end of the paperboard reaches the gap, at this time, the control system controls the lifting device 204, such as a telescopic cylinder, to quickly extend and retract, and the power motor 203 is driven, and the trimming roller 202 is driven to rotate by the servo motor. The trimming roller 202 moves up and down through the end of the paperboard under the driving of the lifting device 204, and the end edge of the paperboard is polished and trimmed.

[0028] If both groups of photoelectric sensors detect the paperboard or neither group of photoelectric sensors detects the paperboard, it indicates that the end of the paperboard does not reach the gap, the lifting device 204 remains in the retracted state, the power motor 203 remains in the low-speed rotation state, and the trimming roller 202 does not perform trimming operation.

[0029] With the continuous movement of the paperboard on the paperboard conveying line 3, the side trimming assembly 4 starts to work. The electric telescopic rod 404 drives the connecting plate 401 to move along the X axis, so that the trimming wheel 403 approaches the side edge of the paperboard.

[0030] An external power input device drives one of the trimming wheels 403 to rotate, and since the adjacent two trimming wheels 403 are drivingly connected through a synchronous transmission mechanism, all the trimming wheels 403 rotate synchronously. The trimming wheel 403 and the movement of the paperboard have a differential speed, so as to realize trimming of the side edge of the paperboard.
