[0031] Example
[0032] like Figure 1 and Figure 2 As shown, the present invention proposes an automatic trimming device for preparing express bags, comprising a mounting frame 1, and a conveyor belt 2 arranged inside the mounting frame 1. A driving device for driving the conveyor belt 2 is installed on one side of the mounting frame 1. As a prior art, it will not be described here. Fixed seats 7 are fixedly installed on both sides of the bottom end of the mounting frame 1. The bottom end of the fixed seat 7 is fixedly connected to a bottom plate 6. The fixed seat 7 makes the installation of the mounting frame 1 more stable.
[0033] In addition, a fixing frame 3 is fixedly connected to the middle of the top of the mounting frame 1, an L-shaped support plate 4 is fixedly installed on one side of the top of the fixing frame 3, a cutting knife 5 is provided at the bottom of the fixing frame 3, and an electric slide rail 12 is provided at the bottom of the fixing frame 3. Two moving blocks 13 are slidably installed in the electric slide rail 12, and a cylinder 14 is fixedly installed at the bottom of the two moving blocks 13. The piston rod of the cylinder 14 is connected to the cutting knife 5. The cutting knife 5 is used to trim the edges of the express bags conveyed on the conveyor belt 2, and the extension of the piston rod of the cylinder 14 drives the cutting knife 5 to descend and contact the express bags;
[0034] It is worth noting that the two moving blocks 13 in the electric slide rail 12 are used to move the two cutting knives 5 toward each other. Specifically, the distance between the cutting knives 5 can be adjusted according to the size of the courier bag, thereby increasing the flexibility and adaptability of the device.
[0035] In addition, a placement box 8 is fixedly installed on the top front side of the installation frame 1, a collection box 9 is fixedly connected to the rear side of the installation frame 1, and fixed rods 10 are fixedly installed on both sides of the outer wall of the collection box 9. A baffle 11 is fixedly connected to the fixed rods 10. Express bags that need to be cut can be placed in the placement box 8. After cutting, the express bags are transported into the collection box 9 through the conveyor belt 2 for centralized storage and processing.
[0036] like Figure 2-Figure 3 As shown, the device also includes a purge device, which is arranged on the L-shaped support plate 4 and is used to automatically clean the debris on the cutting edge of the cutting knife 5 when cutting. The purge device includes a horizontal plate 15 fixedly mounted on the inner side of the L-shaped support plate 4, and a slide groove 16 is opened on the horizontal plate 15. Two sliders 18 are slidably mounted in the slide groove 16, and the two sliders 18 can slide in the slide groove 16;
[0037] Furthermore, a mounting frame 19 is fixedly connected to each of the two sliders 18, and an air pump 20 is fixedly mounted on the mounting frame 19. The air pump 20 is provided with an output pipe 21, and the output pipe 21 is fixedly connected to a plurality of inclined nozzles 22. Compressed air is outputted through the output pipes 21 by the air pump 20, so that the inclined nozzles 22 can blow away debris contaminated on the cutting edge of the cutting knife 5, thereby preventing excessive debris from accumulating and affecting normal cutting operations.
[0038] Furthermore, a screw rod 17 threadedly connected to the two sliders 18 is rotatably installed in the slide groove 16, and opposite internal threads are provided on the inner sides of the two sliders 18. A drive motor 23 is fixedly installed on one side of the cross plate 15, and the output shaft of the drive motor 23 is fixedly connected to the screw rod 17. When the drive motor 23 is started, the screw rod 17 rotates and the two sliders 18 move toward each other. Specifically, it can be adjusted according to the adjustment of the spacing between the cutting blades 5 to ensure that the nozzle 22 can blow and clean up the remaining debris.
[0039] like Figure 2-Figure 4 As shown, the device also includes an auxiliary mechanism, which is arranged on the blowing device for removing impurities that are difficult to clean on the cutting knife 5. The auxiliary mechanism includes a vertical plate 24 fixedly mounted on the horizontal plate 15 and located between the two sliders 18. A rotating rod 25 is rotatably mounted on the vertical plate 24, and a cleaning brush 26 is provided on the curved surface of the rotating rod 25. A motor 27 is fixedly mounted on one side of the vertical plate 24. The output shaft of the motor 27 is fixedly connected to the rotating rod 25. The movement of the moving block 13 is used to drive the two cutting knives 5 to move, so that the cutting knife 5 moves to a position in contact with the cleaning brush 26. The motor 27 is started, so that the rotating rod 25 drives the cleaning brush 26 to rotate, so that the cleaning brush 26 rotates and rubs to clean the impurities and debris at the cutting edge that are difficult to be blown away by the nozzle 22.
[0040] Working principle: The two moving blocks 13 in the electric slide rail 12 are used to move the two cutting knives 5 toward each other. The distance between the cutting knives 5 can be adjusted according to the size of the express bag, which increases the flexibility and adaptability of the device. The drive motor 23 is started to rotate the screw rod 17, and the two sliders 18 move toward each other along the direction of the slide groove 16, so that the two mounting brackets 19 can be adjusted according to the spacing between the cutting knives 5, ensuring that the nozzle 22 is aligned with the cutting edge of the cutting knife 5. The compressed air is output through the output pipe 21 by the air pump 20, so that when the cutting knife 5 is cutting, the nozzle 22 can automatically blow away the debris attached to the surface of the tool to avoid the influence of the debris on the cutting operation, thereby improving the quality of the finished product. Starting the motor 27 makes the rotating rod 25 drive the rotation of the cleaning brush 26, so that the cleaning brush 26 can rotate and rub to clean the impurities on the surface of the tool that are difficult to blow away, thereby improving the cleaning effect.
[0041] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
