Bottle and can recycling equipment

Abstract

A bottle and can recycling device includes a chassis, a conveying device, and a compression device. The chassis includes an inlet. The conveying device is used to transport bottles and cans from the inlet. The compression device includes a collection trough, a drive unit disposed opposite to it, and a pressing member. The collection trough is connected to the drive unit on the side adjacent to the pressing member and is used to hold bottles and cans from the conveying device. When the drive unit is operated under control, causing the collection trough to move towards the pressing member, the collection trough and the pressing member together compress the bottles and cans in the collection trough. By compressing the bottles and cans in one go, the compression device can reliably reduce the size of the bottles and cans and avoid the occurrence of crushing and jamming, thereby improving the operational stability and processing efficiency of the bottle and can recycling device.

Claims

1. A bottle and can recycling device suitable for recycling at least one bottle or can, comprising: a chassis including an inlet for the at least one bottle or can to pass through; a conveying device disposed within the chassis and used for conveying the at least one bottle or can from the inlet; and a compression device disposed within the chassis and adjacent to the side of the conveying device away from the inlet, the compression device including a collection trough for holding the at least one bottle or can from the conveying device, a drive unit disposed opposite to the drive unit, and a pressing member, the collection trough being connected to the side of the drive unit adjacent to the pressing member, the drive unit being controllably operable to move the collection trough toward or away from the pressing member, and when the drive unit is controllably operable to move the collection trough toward the pressing member, the collection trough and the pressing member together compress the at least one bottle or can in the collection trough, thereby compressing the at least one bottle or can.

2. The bottle and can recycling equipment as described in claim 1, wherein, The pressing component has a substrate and a plurality of spikes extending from the substrate toward the collecting groove; during the controlled operation of the driving unit, which moves the collecting groove toward the pressing component, the spikes pierce the at least one bottle, causing the gas inside the at least one bottle to be discharged.

3. The bottle and can recycling equipment as described in claim 2, wherein, The pressing component also has multiple pillars extending from the substrate toward the collecting groove, a movable plate movably disposed on the pillars, and multiple elastic members respectively sleeved on the pillars and located between the substrate and the movable plate. The movable plate has multiple first wall relief holes through which the spikes can pass, and the elastic members can be compressed or return to their original shape. During the controlled operation of the driving unit, which moves the collecting groove toward the pressing component, the movable plate is pushed by the at least one bottle and moves toward the substrate, causing the spikes to pass through the first wall relief holes and pierce the at least one bottle, and the elastic members are pushed and compressed by the movable plate. When the driving unit is controlled to move the collecting groove away from the pressing component, the elastic members return to their original shape and push the movable plate, causing the at least one bottle to be pushed away from the spikes by the movable plate.

4. The bottle and can recycling equipment as described in claim 2, wherein, The pressing component is located above the collection tank and also has multiple pillars extending downward from the substrate, and a movable plate that is movably disposed on the pillars. The movable plate has multiple first wall relief holes through which the spikes can pass. During the controlled operation of the drive unit, which moves the collection tank toward the pressing component, the movable plate is pushed by the at least one bottle and moves toward the substrate, causing the spikes to pass through the first wall relief holes and pierce the at least one bottle. When the drive unit is controlled to move the collection tank away from the pressing component, the movable plate falls downward and pushes the at least one bottle away from the spikes.

5. The bottle and can recycling equipment as described in claim 3, wherein, The collection groove is located below the pressing member and has a bottom wall and a surrounding wall around the bottom wall. The bottom wall and the surrounding wall together define an upward-opening receiving space for inserting at least one bottle or can. The bottom wall has a plurality of second wall clearance holes for the spikes to penetrate. As the collection groove and the pressing member jointly compress the at least one bottle or can in the collection groove, causing the at least one bottle or can to be punctured and compressed, the collection groove continuously moves toward the pressing member, causing the spikes to penetrate the second wall clearance holes.

6. The bottle and can recycling equipment as described in claim 5 further includes a recycling container and a pushing device, wherein, The recycling container is located inside the chassis and adjacent to the collection tank, and is used to hold the at least one compressed bottle from the collection tank; the pushing device is located in the collection tank and is used to push the at least one compressed bottle in the collection tank toward the recycling container.

7. The bottle and can recycling equipment as described in claim 6, wherein, The collection tank also has a base wall connected to the side of the drive unit adjacent to the pressing member, and two side walls extending upward from two opposite sides of the base wall. The tank bottom wall and the base bottom wall are spaced apart, and the two opposite sides of the tank bottom wall are respectively connected to the side walls. The tank bottom wall also has two grooves extending parallel to the side of the side walls facing each other. The pushing device includes a pair of guide rails and a pushing assembly. The pair of guide rails are disposed between the tank bottom wall and the base bottom wall. The pushing assembly has a connecting seat, two connecting posts and a push plate. The connecting seat is movably disposed on the guide rail assembly. The connecting posts extend upward from two opposite sides of the connecting seat and pass through the grooves, and can be driven by the connecting seat to move in the grooves. The two opposite sides of the push plate are respectively connected to the connecting posts. The push plate is located above the tank bottom wall and can be driven by the connecting posts to push the at least one compressed bottle in the collection tank toward the recycling container.

8. The bottle and can recycling equipment as described in claim 1, wherein, The conveying device includes two conveyor belts that convey along a first direction. The conveyor belts are arranged side by side in a second direction perpendicular to the first direction. The top surfaces of the conveyor belts are inclined toward each other and are arranged symmetrically about the center of the conveyor belts in the second direction. The top surfaces of the conveyor belts together define a V-shaped space, into which the bottom of the V-shaped space is used to place the at least one bottle or can during the conveying process.

9. The bottle and can recycling equipment as described in claim 1 further includes a weighing unit, wherein, The weighing unit is located below the conveying device and is used to measure the weight of at least one bottle or can passing through the conveying device.

10. The bottle and can recycling equipment as described in claim 1 further includes a camera unit, wherein, The camera unit is positioned above the conveyor and is used to capture images of at least one bottle passing through the conveyor.

11. The bottle and can recycling equipment as described in claim 1, wherein, The drive unit has a hydraulic pump and a hydraulic cylinder connected to the hydraulic pump and the collection tank. The hydraulic pump can be controlled to drive one end of the hydraulic cylinder to extend or retract, so as to move the collection tank toward the pressing member or away from the pressing member.
