DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine the embodiments to detail this application.

[0028] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0029] As Figures 1-5 shown, the present application provides a cutting device, including a feeding assembly 10 and a cutting assembly 20 fixedly installed on the feeding assembly 10. The feeding assembly 10 is used for placing the packaging bags to be processed as a whole, so that the packaging bags can enter the position of the cutting assembly 20 through the feeding assembly 10, and the cutting assembly 20 is used for cutting the passing packaging bags.

[0030] The feeding assembly 10 includes a workbench 11, on which a motor a 12 is fixedly installed. A collecting roller 13 is fixedly installed on the output shaft of the motor a 12. The collecting roller 13 can store the packaging bags to be processed. At the same time, the collecting roller 13 can be disassembled or installed at the bottom of the workbench 11, so that the packaging bags on the collecting roller 13 can be added at any time.

[0031] A supporting roller 14 is rotatably connected to the workbench 11. The packaging bags on the collecting roller 13 can pass over the supporting roller 14. A positioning roller 15 is rotatably connected to the workbench 11. The positioning roller 15 and the supporting roller 14 are in a horizontal position. And the packaging bags can be tightened when passing over the supporting roller 14. Thus, the tightened packaging bags can be prevented from sliding or deforming during transportation, and can maintain their shape and position, thereby improving the stability. And finally, the packaging bags will pass over the positioning roller 15, and the positioning roller 15 is used for horizontally positioning the packaging bags, so that the packaging bags can be smoothly transported to the cutting assembly 20 for processing.

[0032] The cutting assembly 20 includes a motor b 21. A support frame 22 is fixedly installed at the bottom of the motor b 21. The support frame 22 is used for fixedly installing the motor b 21. At the same time, a bearing rod 23 is fixedly installed on the output shaft of the motor b 21. The bearing rod 23 is installed in the workbench 11 through bearings. A bearing block b 212 is fixedly installed on the bearing rod 23. The bearing block b 212 is not at the center of the circle of the bearing rod 23. At the same time, a support rod 24 is fixedly installed on the bearing block b 212. A cutter 25 is fixedly installed on the support rod 24. The cutter 25 is located on the workbench 11. At the same time, the packaging bags will pass under the cutter 25. And a plurality of groups of rollers 213 are arranged on the outer side of the support rod 24. The ends of the rollers 213 roll on the support rod 24. At the same time, the rollers 213 are used for limiting the left and right movement of the support rod 24. Thus, when the motor b 21 is started, it will drive the bearing rod 23 to rotate, and then the bearing block b 212 will move the support rod 24 up and down through the left and right limiting of the rollers 213. At this time, the cutter 25 can move back and forth synchronously on the workbench 11. When the packaging bags pass under the cutter 25, at this time, when the cutter 25 contacts the packaging bags, the cutting process can be realized.

[0033] Meanwhile, a pressing plate 214 is fixedly installed on one side of the cutting knife 25. When the cutting knife 25 processes the packaging bag, the pressing plate 214 will first contact the packaging bag at this time. The pressing plate 214 can perform a temporary pressing operation on the packaging bag. At this time, the pressing plate 214 can help the cutting knife 25 to perform accurate and clean cutting, ensuring that the cut is neat.

[0034] And an upper transmission module 27 and a lower transmission module 28 are arranged on the workbench 11. The upper transmission module 27 and the lower transmission module 28 include several groups of transmission rollers (not shown in the figure) and belt strips (not shown in the figure). One group of transmission rollers is movably connected to the workbench 11, so that the two structures can be installed on the workbench 11. When the packaging bag is processed by the cutting knife 25, the packaging bag will be processed on the belt strips of the upper transmission module 27 and the lower transmission module 28 at this time. Thus, the two belt strips can simultaneously clamp the upper and lower parts of the packaging bag, thereby avoiding the transportation of the packaging bag by placing it, and thus ensuring the stability of the packaging bag during transportation.

[0035] At the same time, the upper transmission module 27 and the lower transmission module 28 can be integrally driven by an external drive structure. And limit strips 29 are fixedly installed on several groups of transmission rollers on the upper transmission module 27. The limit strips 29 respectively extend out of several groups of belt strips. Thus, when the belt strips are continuously used, at this time, the belt strips can be limited by several groups of limit strips 29, and thus the stability of the use of the belt strips can be ensured.

[0036] A bearing block a211 is also fixedly installed on the bearing rod 23. The bearing block a211 and the bearing block b212 have the same position structure. At the same time, a connecting rod 26 is fixedly installed on the bearing block a211. The connecting rod 26 is movably installed at the end of the upper transmission module 27. When the motor b21 drives the bearing rod 23, it will simultaneously drive the bearing block a211 and the bearing block b212 to move synchronously. When the bearing block a211 is used, it will swing the connecting rod 26 back and forth. Thus, the upper transmission module 27 can move up and down on the workbench 11, and thus the packaging bag can quickly reach the lower transmission module 28.

[0037] Finally, a diversion block 215 is fixedly installed on the workbench 11. At the same time, a collecting plate 216 is arranged on the diversion block 215. Both ends of the collecting plate 216 are fixedly installed with pull rods 217. After the packaging bag is transported by the upper transmission module 27 and the lower transmission module 28, it will be concentrated on the diversion block 215 and will be supported by the collecting plate 216. After the diversion block 215 continuously collects, at this time, the pull rod 217 can be pulled upward to drive the collecting plate 216 to displace, so that the packaging bags collected on the collecting plate 216 can be collectively taken out, and thus it is convenient to transport and transfer the collected packaging bags.

[0038] The present application also provides a plastic packaging device, and the above-mentioned incision device is fixedly installed on the plastic packaging device.

[0039] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
