Description

Technical Field

[0001] The utility model relates to the technical field of automatic cleaning, in particular to an automatic garbage bag packing device and a driverless sweeper with the same. Background Art

[0002] The automatic garbage bag packing device, as the name implies, is a device that can automatically pack and process the garbage swept by a sweeper. At present, the packing technologies applied to sweepers all borrow the principles of household devices. The products that can automatically pack garbage at home are mainly concentrated in household trash cans. It installs a customized garbage bag above the trash can. When in use, the fan at the bottom of the trash can is turned on to unfold the garbage bag. When the garbage is full, after triggering the packing function, the garbage bag is sealed and cut to complete the packing. The existing packing devices need to lift the garbage swept by the rotary brush to a certain height before sending the garbage into the garbage bag when applied to sweepers. It also needs to make major modifications to the trash can part and the chassis of the current sweeper, with complex structures, poor stability, high costs, and unable to meet the continuous use requirements of driverless sweepers.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1-11 , an embodiment of the first aspect of the present invention provides a garbage bag automatic packing device for a sweeper, and most importantly for a driverless sweeper 200. The driverless sweeper 200 includes a dustbin 6. The garbage bag automatic packing device includes: a frame 1 provided with an air duct 11, and the air duct 11 is connected to the suction fan of the sweeper itself. The frame 1 is made of iron material and is installed in the dustbin 6; a garbage bag loading mechanism detachably arranged on the frame 1, including a holding frame 2, and the holding frame includes a first frame body 21 and a second frame body 22; a garbage bag unfolding mechanism 3 including an unfolding bracket 31, and the unfolding bracket 31 is rotatably connected to the frame 1 for opening or resetting the first frame body 21 and the second frame body 22; a garbage bag sealing and cutting mechanism 4 arranged on the frame 1, and the garbage bag sealing and cutting mechanism 4 is located below the garbage bag loading mechanism, including a heating wire 41 and a hot cutting knife 42 for sealing and cutting the garbage bag.

[0037] The garbage bag automatic packing device provided by the embodiment of the first aspect of the present utility model can effectively improve the operation efficiency of the driverless sweeper. During the automatic operation of the driverless sweeper, the most important problem is to timely pour the swept garbage into the trash can. By arranging the garbage bag automatic packing device in the garbage bin 6, loading the customized garbage bag 100 into the garbage bag loading mechanism, using the unfolding bracket 31 to open the holding frame 2, making one side of the customized garbage bag 100 inclined so that the garbage sucked by the sweeper can more easily enter the garbage bag, reducing garbage omission. After the garbage bag is filled with garbage, the garbage bag sealing and cutting mechanism 4 heat-seals the garbage bag through the heating wire 41, and the hot cutting knife 42 cuts the sealed garbage bag, making the sealed garbage bag fall off. The door 61 of the garbage bin 6 is opened, and the garbage bag filled with garbage automatically drops. The operator only needs to collect the dropped garbage bags centrally, and then the air between the frame 1 and the customized garbage bag 100 is sucked out through the air duct 11 by the suction fan, so that the next garbage bag automatically opens. Working in such a cyclic and continuous manner can significantly improve the efficiency of garbage cleaning.

[0038] In an embodiment of the present utility model, preferably, please refer to Figure 7 , the garbage bag loading mechanism further includes a magnet 23. The magnet 23 is arranged at the bottom end of the holding frame 2, and the holding frame 2 is adsorbed on the frame 1 through the magnet 23. A frame cover one 24 is arranged on the frame body one 21, and a frame cover two 25 is arranged on the frame body two 22.

[0039] In this embodiment, the customized garbage bag 100 is placed into the holding frame 2, and the frame cover one 24 and the frame cover two 25 keep the customized garbage bag 100 stable.

[0040] In an embodiment of the present utility model, preferably, please refer to Figure 8 , the garbage bag unfolding mechanism 3 further includes a driving motor M1, a driven bearing 32, a spring 33, an installation groove 34 and a spring accommodating cavity 35. Specifically, the driving motor M1 is installed on one side of the unfolding bracket 31, the driven bearing 32 is installed on the other side of the unfolding bracket 31, the installation groove 34 is arranged at the top end of the unfolding bracket 31 for installing the frame body one 21, the spring accommodating cavity 35 is arranged inside the frame body two 22 and is provided with an opening facing the frame body one 21, one end of the spring 33 is connected to the installation groove 34, and the other end of the spring 33 is arranged in the spring accommodating cavity 35.

[0041] In this embodiment, the unfolding bracket 31 is in a gate shape. One end of the unfolding bracket 31 is arranged at the driving end of the driving motor M1, and the driving motor M1 drives the unfolding bracket 31 to rotate. The driven bearing 32 is arranged inside the frame 1, and a rotating shaft is arranged at the center of the driven bearing 32 and is connected to the unfolding bracket 31. Two springs 33 are provided and are respectively connected to both ends inside the installation groove 34. When the driving motor M1 drives the unfolding bracket 31 to incline outwards, the springs 33 can keep the bag mouth of the garbage bag from sagging.

[0042] In an embodiment of the present utility model, preferably, please refer to Figures 9-11 , the garbage bag sealing and cutting mechanism 4 includes a driving assembly, a support frame 5 and a garbage bag sealing and cutting component. The driving assembly includes a driving motor M2, a driving shaft 43, a synchronous belt 44, a synchronous belt pulley 45 and a driven shaft 46. The support frame 5 is installed on the frame 1. The driving motor M2 is connected to the driving shaft 43. The synchronous belt pulley 45 is connected to the driving shaft 43 through the synchronous belt 44. The driven shaft 46 is installed between the synchronous belt pulleys 45. The synchronous belt 44 drives the garbage bag sealing and cutting component to seal and cut the garbage bag.

[0043] In this embodiment, there are two support frames 5. Driven by the synchronous belt 44, the garbage bag sealing and cutting component reciprocates along the support frame 5.
