[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4 A trimming machine for processing packaging boxes includes a frame 1 and a conveyor belt 7. A groove 11 is formed on the top of the frame 1, and the conveyor belt 7 is disposed within the groove 11. Multiple limiting blocks 19 for blocking collection boxes are bolted to one side of the conveyor belt 7. Two sliding grooves communicating with the groove 11 are formed on the top of the frame 1. A slider 8 is slidably connected within the sliding grooves, and a driving component for moving the slider 8 is provided within the sliding grooves. Multiple fixing blocks 13 are bolted to the top and bottom of the slider 8. A telescopic rod 15 is bolted to one side of each fixing block 13. A connecting block is bolted to one end of the telescopic part of the telescopic rod 15. A grinding wheel 6 in an inclined state is bolted between two opposing connecting blocks. A spring 14 is sleeved on the outside of the frame 1, and the two ends of the spring 14 are fixed to the connecting block and the fixing block 13 respectively. The top of the frame 1 is provided with a deburring component to remove burrs from the trimmed collection box. The packaging box is placed between two adjacent limiting blocks 19 on the conveyor belt 7, so that the limiting blocks 19 block the packaging box. At this time, the inclined grinding wheel 6 will contact the corner of the top of the packaging box under the force of the spring 14. Then the packaging box is conveyed by the conveyor belt 7. During the process of conveying the packaging box, the grinding wheel 6 contacts the packaging box, so the grinding wheel 6 will grind and trim the corner of the packaging box. Multiple packaging boxes can be trimmed at the same time, saving time and improving the trimming efficiency of the packaging box.

[0023] In this invention, the driving component is a second lead screw 9, which is rotatably connected in the slide groove. The second lead screw 9 passes through the slider 8 and is threadedly connected to the slider 8. One end of the second lead screw 9 passes through the frame 1 and is fixed with a knob by bolts. When the second lead screw 9 is rotated, the second lead screw 9 will drive the slider 8 to move along the slide groove through the thread engagement between the second lead screw 9 and the slider 8. The slider 8 will drive the grinding wheel 6 to move, changing the distance between the opposing grinding wheels 6, thereby enabling the trimming of packaging boxes of different sizes.

[0024] Specifically, the deburring assembly includes two support rods 3, both of which are bolted to the top of the frame 1. A slider 8 is located between the two support rods 3. A bidirectional lead screw 4 is rotatably connected between the two support rods 3. Two sliding sleeves 5 are threaded onto the outer side of the bidirectional lead screw 4. Guide grooves 17 are provided on opposite sides of each of the two support rods 3. A tool holder 18 is slidably connected within the guide grooves 17. A tool 16 is bolted to the bottom of the tool holder 18. Two connecting rods are rotatably connected to the top of the tool holder 18, and each connecting rod is rotatably connected to one of the two sliding sleeves 5. A clearance groove 10 is provided on the top of the slider 8, and the tool 16 extends into the clearance groove 10. A rotating hole is provided on one side of one of the support rods 3, and a rotating handle is rotatably connected within the rotating hole. The rotating handle is fixed to the bidirectional lead screw 4. Rotating the bidirectional lead screw 4 causes it to engage with the sliding sleeves 5 via threaded engagement. The sliding sleeve 5 moves, and the sliding sleeve 5 drives the knife holder 18 to move up or down along the guide groove 17 via the connecting rod. The knife holder 18 drives the knife 16 to move, so that the knife 16 contacts the top of the packaging box. At this time, the knife 16 removes burrs from the edge of the packaging box, thereby ensuring the neatness of the edge trimming and improving the use effect of the trimming machine. At the same time, since the height of the knife 16 can be changed, burrs can be removed from packaging boxes of different heights. The top of the frame 1 is located on both sides of the groove 11, and two guide rails 12 are fixed by bolts. The slider 8 moves along the guide rails 12. A collection box 2 is fixed to one side of the frame 1 by bolts. The groove 11 is provided with a ramp that allows the packaging box to slide into the collection box 2. The trimmed packaging box will slide into the collection box 2 through the ramp, so that the collection box 2 collects the packaging box.

[0025] Working principle: When needed, the packaging box is placed between two adjacent limiting blocks 19 on the conveyor belt 7, so that the limiting blocks 19 block the packaging box and limit its movement. At this time, the inclined grinding wheel 6 will contact the corner of the top of the packaging box under the force of the spring 14. Then, the packaging box is conveyed by the conveyor belt 7. During the conveying process, because the grinding wheel 6 is in contact with the packaging box, the grinding wheel 6 will grind and trim the corner of the packaging box. Multiple packaging boxes can be processed simultaneously. The edge trimming process saves time and improves the efficiency of trimming packaging boxes. At the same time, rotating the double-acting screw 4 causes the sliding sleeve 5 to move through the threaded engagement between the double-acting screw 4 and the sliding sleeve 5. The sliding sleeve 5 then drives the tool holder 18 to move up or down along the guide groove 17 through the connecting rod. The tool holder 18 then drives the tool 16 to move, so that the tool 16 contacts the top of the packaging box. At this time, the tool 16 removes burrs from the edge of the packaging box, thereby ensuring the neatness of the edge trimming and improving the use effect of the edge trimming machine.

[0026] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
