DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0019] In the process of making cardboard into cartons, the edges and corners need to be cut off. In the process of cutting the edges and corners, some scraps and flying dust are generated. In order to prevent the flying dust from spreading in the air, it needs to be cleaned up to avoid affecting the health of the workers.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a cardboard corner cutting device, comprising a workbench 1, cleaning mechanisms 5 are arranged on both sides of the top of the workbench 1, the cleaning mechanism 5 comprises two connecting frames 501 fixed on the top of the workbench 1, a screw rod 502 is rotatably connected between the inner walls at both ends of the connecting frames 501, a rotating wheel is fixed on the outer wall of the screw rod 502 after the screw rod 502 passes through the connecting frames 501, a belt is arranged between the two rotating wheels, a first motor is fixed at one end of one of the connecting frames 501, an output end of the first motor passes through the connecting frame 501 and is fixed to the screw rod 502, a slider 503 is screwed on the outer wall of the screw rod 502, a dust hood 504 is fixed on the top of the slider 503, a connecting pipe 507 is fixedly connected to one side of the dust hood 504, a collecting box 505 is arranged at the bottom end of the workbench 1, a filter screen is inserted in the collecting box 505, the connecting pipe 507 is fixedly connected to the collecting box 505, and a fan 506 is fixedly connected to the bottom end of the collecting box 505.

[0021] It should be noted that by starting the first motor, the first motor drives the screw rod 502 to rotate, the rotation of the screw rod 502 drives the slider 503 to move, the movement of the slider 503 causes the dust hood 504 to move, so that the fan 506 sends the flying dust through the dust hood 504 and the connecting pipe 507 into the collection box 505, and filters it through the filter net. In addition, the rotation of one of the screw rods 502 drives the wheel to rotate, and the wheel drives the belt to move, so that the other wheel rotates, so that the other screw rod 502 also rotates, thereby sucking away the flying dust.

[0022] like Figure 1-Figure 4As shown, a support frame 2 is fixed to the top of the workbench 1, and a placement table 3 is rotatably connected between the inner walls at both ends of the support frame 2. A second motor is fixed to one end of the workbench 1, and the output end of the second motor passes through the support frame 2 and is fixed to the placement table 3. A discharge port is provided at the top of the workbench 1, and a placement rack is fixed to the bottom of the workbench 1 just below the discharge port, and a collection drawer 6 is inserted in the placement rack. A telescopic rod 7 is provided on the inner wall at the top of the support frame 2, and a fixing member 8 is fixed to the bottom end of the telescopic rod 7, and a connecting member 13 is inserted in the fixing member 8, and a cutting knife 4 is fixed to the bottom end of the connecting member 13. Both sides of the fixing member 8 are provided with installation openings, and both sides of the fixing member 8 are fixed with connecting sleeves 9, and the connecting sleeves 9 are slidably connected with limit blocks 12. Both sides of the connecting member 13 are provided with grooves 14, and the limit blocks 12 are inserted into the grooves 14. The two limit blocks 12 are fixed with plug rods 11 on the side away from each other, and the plug rods 11 penetrate the connecting sleeves 9. A spring 10 is fixed between the inner wall of the connecting sleeve 9 and the limit blocks 12. A controller 15 is installed at one end of the support frame 2, and the controller 15 is electrically connected to the first motor, the second motor, the fan 506 and the telescopic rod 7.

[0023] It should be noted that the placement table 3 is driven to rotate by the second motor so that the cut scraps fall into the collection drawer 6. In addition, when the cutting knife 4 needs to be replaced, the spring 10 is compressed by pulling the insertion rod 11 outward, and the limit block 12 moves out of the groove 14 and no longer fixes the connecting piece 13. The cutting knife 4 can be taken out and then the connecting piece 13 at the top of another cutting knife 4 is inserted into the fixing piece 8. The limit block 12 is squeezed by the outer wall of the connecting piece 13, so that the spring 10 is compressed. When the connecting piece 13 is fully inserted, the limit block 12 is located on one side of the groove 14. The spring 10 is no longer squeezed, driving the limit block 12 to move and insert into the groove 14 for fixation.

[0024] Working principle: First, by starting the first motor, the second motor and the fan 506, the second motor drives the placement table 3 to rotate, so that the cut scraps fall into the collection drawer 6. When the scraps fall, the first motor drives the screw rod 502 to rotate, and the rotation of the screw rod 502 drives the slider 503 to move, and the movement of the slider 503 causes the dust hood 504 to move. In this way, the fan 506 sends the flying dust through the dust hood 504 and the connecting pipe 507 into the collection box 505, and filters it through the filter. In addition, one of the screw rods 502 rotates to drive the rotating wheel to rotate, and the rotating wheel drives the belt to move, so that the other rotating wheel rotates, so that the other screw rod 502 also rotates, and the two dust hoods 504 move, thereby sucking away the flying dust.

[0025] Although the 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 variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
