Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 and Figure 2, the utility model provides an embodiment: a trimming device for a three-dimensional paper bag, comprising a workbench 1, a vertical plate 3 is fixedly connected to the rear side of the top wall of the workbench 1, and the left and right ends of the rear side of the inner wall of the vertical plate 3 are fixedly connected to the mounting plate 4, and the front side of the mounting plate 4 is fixedly connected to the fixing plate 5, and a swing cylinder 6 is fixedly installed on the right side of the fixing plate 5, and the output end of the swing cylinder 6 passes through the left side of the fixing plate 5 and is fixedly connected to the rotating rod 7, and the bottom of the rotating rod 7 is rotatably connected to the pressing plate 8 through a torsion spring, and a hydraulic rod 9 is fixedly connected to the top of the vertical plate 3, and the output end of the hydraulic rod 9 is fixedly connected to the mounting shell 10, and the left and right sides of the top wall of the mounting shell 10 are threaded with a threaded knob 11, and the bottom end of the threaded knob 11 is threadedly connected to a cutting knife 12, and a cutting plate 15 is fixedly connected to the middle part of the top wall of the workbench 1, and a collecting mechanism 2 is provided on the bottom wall of the workbench 1, and the collecting mechanism 2 is used to collect paper scraps generated by cutting;

[0031] Specifically, by starting the swing cylinder 6, the force is transmitted to the rotating rod 7, causing the rotating rod 7 to start to swing. The pressing plate 8 is connected to the bottom of the rotating rod 7. When the rotating rod 7 swings, the pressing plate 8 rotates downward accordingly. The torsion spring on the top of the pressing plate 8 provides a reaction force, so that the pressing plate 8 can stably and appropriately press the three-dimensional paper bag during the descent process, ensuring the fixity of the paper bag during the trimming process and avoiding errors caused by the movement of the paper bag. By turning the threaded knob 11, the cutting knife 12 can be selectively installed or replaced. One end of the hydraulic rod 9 drives the cutting knife 12 to perform precise trimming action on the three-dimensional paper bag, ensuring the accuracy and stability of the cutting.

[0032] Reference Figure 1 , two support plates 18 are fixedly connected to the left and right sides of the workbench 1, and support columns 19 are fixedly connected to the interior of the multiple support plates 18; the outer wall of the workbench 1 is smooth in design, and the front and rear sides of the cutting knife 12 are both provided with inclined surfaces;

[0033] Specifically, the support plate 18 and the support column 19 make the device more stable during operation, and the outer wall of the workbench 1 is designed to be smooth, so that the pressure resistance of the workbench 1 is improved.

[0034] Reference Figure 1 and Figure 3 The collecting mechanism 2 includes an extraction fan 201, the top wall of the extraction fan 201 is fixedly connected to the rear side of the bottom wall of the workbench 1, the output end of the extraction fan 201 is connected to a collection box 202, a filter plate 203 is fixedly installed inside the collection box 202, the front side of the collection box 202 is connected to an extraction shell 204, the front end of the extraction shell 204 is connected to an extraction head 205, the top wall of the extraction head 205 is fixedly connected to the front side of the bottom wall of the workbench 1, and a plurality of through slots 206 are equidistantly provided inside the workbench 1;

[0035] Specifically, when the extraction fan 201 is started, an extraction airflow can be generated. The through groove 206 guides the paper scraps generated after cutting to ensure that they are accurately introduced into the extraction airflow. After the paper scraps are guided into the airflow, they will be sucked into the collection box 202, thereby completing unified processing. Before the paper scraps enter the extraction fan 201, the filter plate 203 acts as a barrier, which can effectively intercept most of the paper scraps and prevent them from entering the fan and causing damage to the equipment.

[0036] Reference Figure 1 , Figure 2 and Figure 3 A control switch 16 is fixedly connected to the rear side of the vertical plate 3, and the control switch 16 is electrically connected to the swing cylinder 6, the hydraulic rod 9 and the extraction fan 201 respectively; a protective shell 17 is provided on the rear side of the vertical plate 3, and the left side of the protective shell 17 is rotatably connected to the right side of the control switch 16 through a hinge;

[0037] Specifically, through the control switch 16 electrically connected to the swing cylinder 6, the hydraulic rod 9 and the extraction fan 201 respectively, the control switch 16 can complete the opening and closing of the device, and the protective shell 17 makes it convenient to protect the control switch 16. The model of the swing cylinder 6 used in the utility model is the swing cylinder QGK, the model of the hydraulic rod 9 is the hydraulic rod GYCD-110 / 750, the model of the extraction fan 201 is the axial flow fan T4-72, and the model of the control switch 16 is the control switch lw2.

[0038] Reference Figure 2 The middle parts of the two threaded knobs 11 are fixedly connected with rubber rings 13, and one side of the multiple rubber rings 13 is respectively arranged on one side of the corresponding mounting shell 10; the bottom walls of the two clamping plates 8 are fixedly connected with rubber pads 14, and the shapes of the two rubber pads 14 are both square in design;

[0039] Specifically, the rubber ring 13 reduces the rotation damage of the threaded knob 11 to the mounting shell 10 , and the rubber pad 14 improves the fixing effect of the three-dimensional paper bag.

[0040] Working principle: When starting to use, place the three-dimensional paper bag on the top of the cutting plate 15, and start the swing cylinder 6 to drive the rotating rod 7 to drive the pressing plate 8 to rotate downward, so that the pressing plate 8 can press the three-dimensional paper bag under the action of the torsion spring, so that multiple three-dimensional paper bags can be fixed, and the selected cutting knife 12 can be installed or replaced by turning the threaded knob 11, so that the cutting knife 12 can trim the fixed three-dimensional paper bag under the drive of one end of the hydraulic rod 9;

[0041] And after the cutting is completed, the cut paper scraps can be guided through multiple through slots 206. When the extraction fan 201 is started, the extraction head 205 can generate an extraction airflow, and then extract the paper scraps guided through the through slots 206, so that the airflow carrying the paper scraps passes through the extraction shell 204 into the interior of the collection box 202, and then under the obstruction of the filter plate 203, the paper scraps are placed into the interior of the extraction fan 201, and then the airflow is discharged through the output end of the extraction fan 201.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
