[0021] Example

[0022] See also Figures 1 to 4 In an embodiment of the present invention, a cutting device for processing packaging bags includes a fixing plate 1, and a bracket 2 is provided at the bottom of the fixing plate 1. Under the action of the bracket 2, the stability of the device during actual use is guaranteed.

[0023] The fixed plate 1 is also provided with a conveyor belt, under the action of the conveyor belt, the packaging bags can be continuously conveyed, thereby ensuring the subsequent cutting efficiency of the packaging bags. A mounting bracket 3 is provided on the left side of the top of the fixed plate 1, and a slide plate 4 is slidingly provided on the mounting bracket 3. A first slide groove 301 is provided on the inner wall of the mounting bracket 3, and the slide plate 4 is slidingly connected to the mounting bracket 3 through the first slide groove 301. A number of fixed blocks 5 are evenly arranged on the bottom of the slide plate 4, and a pressing roller 6 is provided on the bottom of the fixed block 5 through the support plate rotation. At this time, under the action of the pressing roller 6, the packaging bags conveyed on the conveyor belt can be pressed, thereby ensuring that the packaging bags can always be in a flat state during subsequent cutting, thereby ensuring the cutting quality of the packaging bags by the device.

[0024] A threaded hole is provided on the mounting frame 3, and a threaded rod 7 is provided in the threaded hole through a threaded connection. The bottom of the threaded rod 7 is connected to the slide plate 4 through a rotating sleeve. At this time, rotating the threaded rod 7 can drive the slide plate 4 to move, so that the pressing roller 6 can better press and convey the packaging bag. A rotary handle 701 is provided at the top end of the threaded rod 7. By rotating the rotary handle 701, the threaded rod 7 can be driven to rotate, so that the pressing roller 6 can better press the packaging bag.

[0025] A fixing frame 8 is also provided on the fixing plate 1 to the right of the mounting frame 3, a lifting plate 9 is slidingly provided on the fixing frame 8, a second slide groove 801 is provided on the inner wall of the fixing frame 8, the lifting plate 9 is slidingly connected to the fixing frame 8 through the second slide groove 801, and a cutter 10 is provided at the bottom of the lifting plate 9. At this time, the packaging bag can be cut by moving the cutter 10 up and down.

[0026] The fixing frame 8 is also rotatably provided with an installation shaft 12, and a half gear 13 is provided on the installation shaft 12 through a key connection. A rack 11 is also provided on the side wall of the lifting plate 9, and the rack 11 and the half gear 13 are meshed with each other. At this time, under the action of the half gear 13, the lifting plate 9 can be driven to move upward. A number of telescopic rods 14 are also evenly provided on the fixing frame 8. The end of the telescopic arm of the telescopic rod 14 is connected to the lifting plate 9. A return spring 15 is also sleeved on the outside of the telescopic rod 14. One end of the return spring 15 is connected to the lifting plate 9, and the other end of the return spring 15 is connected to the fixing frame 8. At this time, under the action of the return spring 15, the cutter 10 can be moved downward, thereby completing the cutting quality of the packaging bag. A motor 1201 is also provided on the side wall of the fixing frame 8. The power output shaft of the motor 1201 is connected to the installation shaft 12 through a coupling. At this time, under the action of the motor 1201, the installation shaft 12 can be driven to rotate.

[0027] During actual use, the packaging bags to be cut are continuously conveyed to the working area of the device through the conveyor belt. During this process, the packaging bags are placed steadily on the conveyor belt and move forward with the movement of the belt. The pressing roller system on the mounting bracket on the top of the fixed plate starts to work. By rotating the handle 701, the threaded rod 7 rotates in the threaded hole and moves downward. By rotating the sleeve, the slide plate 4 is driven to slide down along the first slide groove 301. The fixed block 5 and the support plate on the slide plate 4 then drop, so that the pressing roller 6 is close to and gently presses the packaging bags on the conveyor belt. This step ensures that the packaging bags are in a flat state before cutting, which helps to improve the cutting accuracy and quality. When the packaging bags are stably pressed and conveyed to the cutting area, the motor 1201 is started, and its power output shaft drives the mounting shaft 12 to rotate through the coupling. The half gear 13 on the mounting shaft 12 begins to engage with the rack 11 on the side wall of the lifting plate 9. As the half gear 13 rotates, the rack 11 The lifting plate 9 and the cutter 10 at the bottom are pushed and moved upward along the second slide 801. At this time, due to the initial state of the telescopic rod 14 and the return spring 15, they are stretched or compressed, but do not hinder the movement of the lifting plate 9. When the engagement of the half gear 13 with the rack 11 reaches a predetermined position, the motor 1201 may temporarily stop or change direction, so that the half gear 13 is separated from the rack 11. At this time, under the elastic force of the return spring 15, the telescopic rod 14 quickly returns to its original length, pushing the lifting plate 9 and the cutter 10 to move downward quickly to cut the packaging bag below. After the cutting is completed, the motor 1201 may start again, repeat the above process or perform the reverse operation, so that the half gear 13 is engaged with the rack 11 again, and the cutter 10 is lifted back to the initial position to prepare for the next cutting. At the same time, the conveyor belt continues to move forward, sending the cut packaging bags out of the working area and introducing new packaging bags for the next round of processing.
