Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more, unless otherwise specifically defined.
[0026] Currently, after bag-breaking treatment, the separation between the garbage and the bag is often not thorough enough, which directly leads to the difficulty in completely separating the garbage bag from the kitchen waste during the subsequent garbage classification process. Therefore, to solve the above problems, the following technical solutions are proposed in this case: Please refer to Figures 1 to 6 , the present invention provides a technical solution for an automatic separation and sorting machine for domestic waste: its structure includes: a bracket 3, a feeding hopper 2 is provided at the top of the bracket 3, a bag-breaking device 1 is installed inside the feeding hopper 2, a movable sorting bucket 4 is installed at the bottom of the bracket 3, a controller 5 is installed on the surface of the bracket 3, the feeding hopper 2 includes a cover body formed by a fence 21 and an inner bin 24, the bag-breaking device 1 is installed inside the cover body, a feeding belt 22 is installed between the fences 21, and a first driver 25 and a second driver 26 are installed on the side of the feeding belt 22 to drive the feeding belt 22 and the bag-breaking device 1 to move respectively; The bag-breaking device 1 includes a crushing knife group 11, a material distributor 12, and a selection belt 13. The crushing knife group 11 is installed in the opening of the fence 21, the crushing knife group 11 is movably connected to the material distributor 12, a selection belt 13 is provided at the bottom of the crushing knife group 11 and the material distributor 12, the selection belt 13 is located between two sorting buckets 4, and the surface of the feeding belt 22 is provided with protrusions, and a limiting groove 23 is opened on the surface of each protrusion.
[0027] The main structure of this device includes a bracket 3. At the bottom of the bracket 3, there is a sorting bin 4 for sorting. The sorting bin 4 is mainly divided into a food waste bin and a plastic bag recycling bin. On the side of the bracket 3, there is a controller 5, which is the circuit controller of this device. At the top of the bracket 3, there is a feeding hopper 2, which is mainly used to convey bagged food waste. The main structure of the feeding hopper 2 includes a retaining wall 21, which is used to protect and prevent the garbage bag from falling out during transportation. Inside the retaining wall 21, there is a feeding belt 22, which is driven by a first driver 25. When the protrusions of the feeding belt 22 rotate, they can push the garbage bag to the inner bin 24 for bag breaking and recycling through the bag breaking device 1. On the side of the retaining wall 21, there is also a second driver 26 for driving the bag breaking device 1. The bag breaking device 1 has two power sources, one is the second driver 26 and the other is the third driver 111. The second driver 26 is connected to the drive shaft 113, so that when the pull plate 115 rotates, it can form different rotation speeds with the knife shaft 112, and avoid crushing the garbage bag together with too fast a rotation speed when breaking the garbage bag.
[0028] Specifically, the structure of the bag breaking device 1 includes a crushing knife group 11 for breaking and separating garbage. A material distributor 12 is arranged adjacent to the crushing knife group 11. The material distributor 12 is used to drag the garbage bag to squeeze out the remaining garbage inside the garbage bag. At the bottom of the material distributor 12, there is a selection belt 13. The main function of the selection belt 13 is to convey the separated food waste to a special box, and convey the processed garbage bag to a special box. The selection belt 13 can rotate forward and backward, and can quickly convey the specified items to the specified area during sorting.
[0029] The mechanism of the crushing knife group 11 for bag breaking is the knife shaft 112. The knife shaft 112 is a knife roller body, which breaks the garbage bag during rotation. There is an independently rotating pull plate 115 on the side of the knife shaft 112. One side of the pull plate 115 is connected to the second driver 26. An inner tube 114 is opened inside the drive shaft 113. By connecting the inner tube 114 to the pull plate 115, the pull plate 115 can generate negative pressure. Specifically, the inner tube 114 is connected to an external negative pressure machine, and the pull plate 115 adsorbs the garbage bag by sucking out the air flow through negative pressure. After adsorption, the second driver 26 drives the pull plate 115 to rotate to push the garbage bag in the reverse direction.
[0030] The structure of the pull plate 115 includes an internal flow channel 155 connected to the air pipe. The internal flow channel 155 is installed inside the plate body 151. The suction opening is located at the narrower part of the diamond-shaped plate body 151. When adsorbing, a suction negative pressure is generated on the diamond sides. The adsorption flow channel 154 communicates with the adsorption ring 152. To avoid blockage, a retaining net 153 is arranged on the surface of the adsorption ring 152 to cover it, preventing the garbage bag from blocking the adsorption ring 152 during adsorption. And due to the function of the retaining net 153, the garbage bag can be evenly adsorbed on the surface. When it rotates to the diverter 12, the plate body 151 passes through the desorption groove 123, making the garbage bag on the surface of the second plate body 122. When the feeding belt 22 rotates, it will contact the surface of the second plate body 122. During rotation, the garbage bag is squeezed to drag the garbage bag along the surface of the second plate body 122.
[0031] To further improve the separation effect between the garbage bag and the garbage, the device is provided with a desorption belt 125 and a driving roller set 126 in the middle of the second plate body 122. The driving roller set 126 is driven to rotate by the fourth driver 121. The moving speed of the desorption belt 125 is greater than that of the feeding belt 22. Then, the garbage bag can be pulled to move through the puncture on the surface of the desorption belt 125. When the garbage bag moves quickly, it passes through the gap between the second plate body 122 and the feeding belt 22. The surface of the feeding belt 22 is provided with a limiting groove 23 to match the desorption belt 125. When pulled quickly, the garbage inside the garbage bag will fall onto the surface of the selection belt 13 through the separation grooves 124 on both sides of the second plate body 122 for quick cleaning.
[0032] After the improvement of the device, the pull plate 115 is used to pull the garbage bag-type cutter shaft 112 to open the bag body, so that the garbage is recycled into the classification bucket 4 at the bottom. The garbage bag is adsorbed through the adsorption ring 152 on the surface of the plate body 151. Under the protection of the retaining net 153, the garbage bag is evenly stressed, avoiding the garbage bag from being broken during the dragging process. After the garbage bag is transported to the surface of the diverter 12, the differential speed between the desorption belt 125 and the feeding belt 22 is used to drag the garbage bag between the scrapers on the surface of the feeding belt 22, squeezing the garbage out of the garbage bag and making it fall off through the separation grooves 124. It is more convenient to use, avoiding the trouble of residual garbage remaining in the bag after the garbage bag is broken.
[0033] Only the basic principle and preferred implementation mode of the present invention are described above. Those skilled in the art can make many changes and improvements according to the above description, and these changes and improvements should belong to the protection scope of the present invention.
[0034] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
