[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] See also Figure 1-3 A trimming assembly for processing packaging paperboard includes a device table 1, a mechanical arm 2 is arranged on the device table 1, a cutting machine 3 is fixedly installed on the mechanical arm 2, a stop plate 4 is fixedly connected to the top of the device table 1, a guide plate 5 is fixedly connected to the front end surface of the device table 1, a fixing frame 6 is fixedly connected to the end of the top of the device table 1 away from the stop plate 4, and an auxiliary trimming mechanism for automatically positioning and removing the packaging paperboard is arranged on the fixing frame 6.

[0020] Through the above technical solution, when the device is in use, the packaging cardboard is placed on the device table 1, and is stabilized and limited by the auxiliary trimming mechanism to avoid deviation during the trimming process. The robot arm 2 adjusts the position of the cutting machine 3, and the cutting machine 3 trims the packaging cardboard. Finally, the auxiliary trimming mechanism releases the positioning of the packaging cardboard and automatically removes the cardboard.

[0021] Specifically, the auxiliary trimming mechanism includes a motor 7 fixedly mounted on a fixing frame 6 , an output end of the motor 7 is fixedly connected to a driving shaft 8 , and a side gear 9 is fixedly sleeved on an outer surface of the driving shaft 8 .

[0022] Through the above technical solution, when the gear teeth of the side gear 9 and the lower gear 11 are meshed, the pressure angle of the gear teeth determines the lateral force component of the gear, and this lateral force component causes the lower gear 11 to generate a rotational torque, causing it to rotate together with the side gear 9.

[0023] Specifically, the inner surface of the fixed frame 6 is rotatably connected with a rotating shaft 10 , a lower gear 11 is provided on the top of the rotating shaft 10 , the outer surface of the lower gear 11 is meshedly connected with the outer surface of the side gear 9 , and an eccentric wheel 12 is fixedly connected to the bottom of the rotating shaft 10 .

[0024] Through the above technical solution, the lower gear 11 will drive the eccentric wheel 12 to rotate through the rotating shaft 10 during the rotation process, so that the first shaft 13 performs a relative circular motion.

[0025] Specifically, the outer surface of the eccentric wheel 12 is fixedly connected to the first shaft 13 , the outer surface of the first shaft 13 is rotatably connected to the connecting bar 14 , and one end of the connecting bar 14 away from the first shaft 13 is rotatably connected to the second shaft 15 .

[0026] Through the above technical solution, the first shaft 13 will pull the connecting rod 14 during the process of corresponding rotation under the rotation of the eccentric wheel 12.

[0027] Specifically, the outer surface of the fixing frame 6 is fixedly connected to the guide rail 16, the inner surface of the guide rail 16 is slidably connected to the positioning rod 17, the end of the positioning rod 17 close to the connecting bar 14 is fixedly connected to the fixing plate 18, and the outer surface of the fixing plate 18 is fixedly connected to one end of the second shaft 15.

[0028] Through the above technical solution, the guide rail 16 plays a role in guiding the positioning rod 17, so that the positioning rod 17 moves along a fixed track through the guide rail 16.

[0029] Specifically, one end of the driving shaft 8 away from the motor 7 is fixedly connected with a rotary disk 19 , and a lower lever 20 is provided on the outer surface of the rotary disk 19 .

[0030] Through the above technical solution, the driving shaft 8 will drive the turntable 19 to rotate during the rotation process, thereby adjusting the position of the lower lever 20. When the positioning rod 17 stably presses against the packaging cardboard, the lower lever 20 does not contact the packaging cardboard.

[0031] Working principle: When the device is trimming the packaging cardboard, the packaging cardboard is located on the device table 1, and one end of the packaging cardboard is against the stop plate 4. In order to ensure the stability of the trimming and prevent the packaging cardboard from being offset, the motor 7 can be turned on to drive the drive shaft 8 to rotate. During this process, the side gear 9 will rotate synchronously and drive the lower gear 11 to rotate. The rotating shaft 10 and the eccentric wheel 12 at the bottom of the lower gear 11 will rotate accordingly. The eccentric wheel 12 will drive the first shaft 13 to rotate during the rotation process, so that the two ends of the connecting bar 14 rotate along the first shaft 13 and the second shaft 15 respectively. Finally, the rotation of the eccentric wheel 12 will drive the fixed plate 18 to move, and under the guidance of the guide rail 16, the positioning rod 17 stably presses against the packaging cardboard, that is, the packaging cardboard is stably positioned between the stop plate 4 and the positioning rod 17. The motor 7 is braked at this time. During this process, the rotation of the drive shaft 8 will drive the turntable 19 and the lower lever 20 to rotate synchronously, but the rotation angle of the turntable 19 is limited, and the lower lever 20 will not contact the packaging cardboard. After the positioning is completed, the position of the cutting machine 3 can be adjusted by the mechanical arm 2, so that it can smoothly trim the packaging cardboard. After the trimming is completed, the motor 7 is turned on again to push the positioning rod 17 back along the guide rail 16, and the packaging cardboard is no longer held and positioned. At this time, under the rotation of the drive shaft 8, the turntable 19 will drive the lower lever 20 to rotate, and let the end of the lower lever 20 away from the turntable 19 contact the packaging cardboard, and push the cardboard to make it detach from the device table 1, and finally slide along the guide plate 5 to the specified collection position, so as to realize the automatic collection of the packaging box after trimming.

[0032] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
