[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides a waste suction device inside a die-cutting machine, such as Figure 1-5 As shown, the waste suction device includes a box body 1 with an open top, a scraper 2 is slidably connected to the inside of the box body 1, and a rack 3 is fixedly connected to the outer wall of the scraper 2. The outer wall of the box body 1 is rotatably connected to a rotating rod 4. The outer wall of the box body 1 is provided with a motor 5 for driving the rotating rod 4 to rotate, and the outer surface of the rotating rod 4 is fixedly connected to a turntable 6. The inside of the turntable 6 is hinged with a connecting rod 7, and the end of the connecting rod 7 away from the turntable 6 is hinged with a connecting block 8 fixedly connected to the scraper 2. The inner cavity of the box body 1 is provided with a blower 9, and the inner cavity of the air inlet of the blower 9 is connected to the inner cavity of the box body 1.

[0025] The top of the box body 1 is open so that the waste can fall into the box body 1 smoothly, which is convenient for centralized suction and processing. The box body 1 is sealed all around, which makes it difficult for the waste to be scattered at will, which is conducive to the blower 9 to absorb the waste. The motor 5 enables the rotating rod 4 to rotate, so that when the motor 5 is running, it can drive the rotating rod 4 to rotate, so that when the rotating rod 4 drives the turntable 6 to rotate, the turntable 6 can use the hinge between the connecting rod 7 to prompt it to be hinged with the connecting block 8 to drive the connecting block 8 to move repeatedly, so that when the connecting block 8 drives the scraper 2 to move repeatedly, the waste in the box body 1 can be pushed to the two sides of the bottom of the box body 1 corresponding to the positions of the two blowers 9. At the same time, the repeated movement can push the waste that falls into the box body 1 to both sides of the box body 1 for circulation, so that the two blowers 9 can suck in the waste and prevent the blower 9 from being unable to suck in the waste in some positions due to the suction dead corner. The blower 9 can suck in the waste in the box body 1 and then discharge the waste through the air outlet.

[0026] A rotating shaft 10 is rotatably connected to the air inlet of the blower 9, and a gear 11 meshing with the rack 3 is fixedly connected to the outer surface of the rotating shaft 10. The end of the rotating shaft 10 away from the gear 11 is fixedly connected to a fan blade 12 located at the air inlet of the blower 9 for fanning the waste.

[0027] In addition, the scraper 2 can drive the rack 3 to move repeatedly synchronously, so that the gear 11 engaged with the rack 3 can drive the rotating shaft 10 to rotate. When the rotating shaft 10 drives the fan blades 12 to rotate, the suction point of the blower 9 can be prevented from being blocked, preventing the blower 9 from being blocked when it inhales a large amount of waste, facilitating the subsequent absorption of waste by the blower 9, and improving the efficiency of the continuous operation of the blower 9.

[0028] The outer wall of the box body 1 is threadedly connected with a threaded rod 19 , and one end of the threaded rod 19 away from the box body 1 is fixedly connected with a stabilizing pad 20 .

[0029] The threaded rod 19 utilizes the threaded cooperation with the box body 1 to drive the stabilizing pad 20 to move downward smoothly, so that the stabilizing pad 20 can provide a certain friction force when in contact with the ground to make the box body 1 more stable when it is located on the ground, and prevent the box body 1 from having slight displacement when the structure installed on the box body 1 is in operation.

[0030] A collecting box 17 with an opening on one side is fixedly connected to the air outlet of the blower 9 , and the inner cavity of the air outlet of the blower 9 is communicated with the inner cavity of the collecting box 17 .

[0031] The collection box 17 provides a collection point for the waste discharged by the blower 9, preventing the waste from being scattered on the ground when discharged by the blower 9, thereby avoiding manual secondary cleaning. At the same time, when the waste is concentrated in one place, it is convenient for subsequent processing, thereby reducing labor consumption.

[0032] A baffle 18 for shielding the opening is slidably connected to the interior of the collecting box 17 , and a through hole 13 for the scraper 2 to slide is provided inside the box body 1 .

[0033] The baffle 18 can open or close the opening of the collection box 17, so that the opening can be opened or closed appropriately according to the waste processing requirements, preventing the waste in the collection box 17 from scattering outward, thereby avoiding manual secondary cleaning. At the same time, the through hole 13 provides space for the scraper 2 to move, so that the scraper 2 can move smoothly, preventing it from offsetting and being unable to push the waste in the box body 1, thereby ensuring that the waste can be smoothly located on both sides of the inside of the box body 1 for the blower 9 to absorb the waste.

[0034] A slider 14 is fixedly connected to the bottom of the connecting block 8 , and a connecting plate 15 is fixedly connected to the outer wall of the box body 1 . A sliding groove 16 for the slider 14 to slide is provided inside the connecting plate 15 .

[0035] The slide groove 16 provides the slider 14 with an embedded moving space, thereby further improving the stability of the connection block 8 driving the scraper 2 to move, thereby ensuring that the scraper 2 will not deviate or fall off during the movement, so that the scraper 2 can smoothly push the waste in the box 1 to both sides for the blower 9 to suck in.

[0036] Working principle:

[0037] When it is necessary to use this device to collect the waste generated during the operation of the die-cutting machine, first start the motor 4 so that the output shaft of the motor 4 can drive the rotating rod 3 to rotate, and the rotating rod 3 drives the turntable 5 to rotate, prompting the turntable 5 to utilize the hinge between the connecting rod 6 and the hinge between the connecting block 8 to drive the connecting block 8 to move repeatedly, so that the connecting block 8 can drive the scraper 2 to move repeatedly, so that the scraper 2 can push the waste in the box 1 to the two sides corresponding to the suction points of the blower 9.

[0038] At this time, the blower 9 can be used to suck in the waste at the current location, and then the waste can be discharged into the collection box 14 through the air outlet, and the scraper 2 can drive the rack 3 to move synchronously, so that the gear 11 engaged with the rack 3 can drive the rotating shaft 10 to rotate, so that when the rotating shaft 10 drives the fan blades 11 to rotate, the waste sucked in at the air inlet of the blower 9 can be prevented from being blocked.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
