Rotation of the rotational frame around the fixed shaft can drive a plurality of first gears to revolve around an outer circumferential face of the second gear, and at the same time, with the engagement of the second gear and the first gear, the second gear can drive the first gear to perform autorotation. The autorotation of the first gear can drive, through the crank and the link, the frame to slide along the track member.
The four side tray walls of the placing tray are each provided with an opening. A clamping mechanism 21 is mounted at the opening.
The clamping mechanism includes a mounting plate 21-1 secured to the bottom tray wall at a position corresponding to the opening. A hinged seat 21-2 is secured to the mounting plate. The hinged seat is separately hinged to one end of a first connecting plate 21-3 and one end of a second connecting plate 21-4 disposed in parallel with the first connecting plate.
Two sides of the hinged seat are both hinged to the first connecting plate and the second connecting plate. The other end of the first connecting plate and the other end of the second connecting plate are respectively hinged to one end and a middle position of a second link 21-5. The hinged seat, the first connecting plate, the second connecting plate, and the second link form a parallelogram link mechanism. The other end of the second link is hinged to one end of a third connecting plate 21-6. Two sides of the second link are both hinged to the third connecting plate. The other end of the third connecting plate is connected to a second driving member. A compression hook 21-7 is secured in one piece to two first connecting plates.

The second driving member can drive, through the third connecting plate, the second link to move. The second link drive, through the first connecting plate and the second connecting plate, the compression hook to sway, to compress and loosen the dinner tray.
The second driving member includes a lifting frame 22. The lifting frame includes a connecting disc 22-1. Four lifting rods 22-2 are secured around the connecting disc. An end of the lifting rod is provided with a bending rod 22-3. The bending rod is hinged to the end of the third connecting plate. The connecting disc is threadedly connected to a lead screw 24. An axis of the lead screw is perpendicular to the bottom tray wall, and the lead screw is disposed coaxially with the bottom tray wall. Rotation of the lead screw can drive the lifting frame to move along a direction of the axis of the lead screw. One end of the lead screw is rotatably connected to the bottom tray wall through a bearing and runs through the bottom tray wall. A centering roller 25 is secured to the end that is of the lead screw and that runs through the bottom tray wall. The centering roller is above the bottom tray wall. The lead screw can drive the centering roller to rotate, so as to center the dinner tray placed in the placing tray. The centering roller is a round plate. The round plate can drive, by using a friction force, the dinner tray to rotate, until the dinner tray is in contact with the side tray walls to finish dinner tray centering work.
The other end of the lead screw is connected to a second motor 27 through a bevel gear transmission mechanism 26. The second motor can drive, through the bevel gear transmission mechanism, the lead screw to rotate. The second motor is mounted on a motor cabinet 28.
The motor cabinet is fixedly connected to the bottom tray wall.
A mesh belt conveying mechanism 29 is disposed in the dumping region. The mesh belt conveying mechanism is below the placing trays. After the placing tray overturns 180, the dinner tray can dump the little bowl and leftovers in the dinner tray into the mesh belt conveying mechanism.
An existing mesh belt conveying mechanism can be used as the mesh belt conveying mechanism. The mesh belt conveying mechanism includes a driving roller, a driven roller, and a conveying mesh belt forming a wrapped connection between the driving roller and the driven roller. The driving roller is connected to a third motor 30 secured inside the housing. The third motor is secured inside the housing through a motor support. The third motor can drive the driving roller to rotate. An end of the driving roller and an end of the driven roller are rotatably connected to a conveying roller support. The conveying roller support is secured inside the housing.
The conveying mesh belt has cracks. The leftovers can be leaked from the cracks of the conveying mesh belt. A first recycling box 31 open at the top is disposed below the conveying mesh belt. The first recycling box is configured to recycle the leftovers leaked from the conveying mesh belt.
Four drawers 31-1 are disposed in the first recycling box. The bottom of the drawer and the bottom of the first recycling box are disposed aslant to facilitate takeout of the leftovers from the first recycling box. The leftovers that are to fill up the drawers are taken out for clearing without affecting the normal operation of the entire recycling device.
A brush 32 is disposed above a tail end of the mesh belt conveying mechanism. Two ends of the brush are rotatably connected to the housing, and the brush is connected to the third motor through a belt transmission mechanism 33. The third motor can drive the brush to rotate. The brush can clean the surface of the dinner tray, to maximally clear away the leftovers on the surface of the dinner tray.
A second recycling box 34 open at the top is disposed on one side of the tail end of the mesh belt conveying mechanism. The second recycling box is configured to recycle the little bowl. The little bowl falling onto the conveying mesh belt from the dinner tray can fall into the second recycling box under the action of the conveying mesh belt. Therefore, the dinner tray and the little bowl are recycled separately.
A third recycling box 35 open at the top is disposed in the recycling region. The third recycling box is configured to recycle the dinner tray. One side of the third recycling box is provided with a guide member 36. The guide member is secured to the housing through a fixing rod and can guide the dinner tray falling from the placing tray into the third recycling box.
The guide member includes a guide bottom plate. Guide side plates are secured to two sides of the guide bottom plate. The width of one end of the guide bottom plate near the third recycling box is less than that of the other end, and the width of the end of the guide bottom plate near the third recycling box is slightly greater than the side length of the dinner tray. Therefore, dinner trays can be guided into the third recycling box orderly, so as to pile up the dinner trays neatly in the third recycling box.
A first infrared sensor 37 connected to a controller is mounted on the rotational shaft. A second infrared sensor 38 connected to the controller is mounted on the mounting block. Infrared emitters matching the first infrared sensor and the second infrared sensor are mounted at corresponding positions in the housing.
Before the placing tray into which the dinner tray is placed enters the dumping region from the tray-receiving region, the first infrared sensor senses rays emitted from the first infrared emitter disposed in the housing and generates and transmits a signal to the controller. The controller controls the second motor to drive the clamping mechanism to clamp the dinner tray. When the placing tray moves to a position above the third recycling box, the second infrared sensor can sense rays emitted from the second infrared emitter 39 secured to the fixed shaft, and generates and transmits a signal to the controller. The controller controls the clamping mechanism to loosen the dinner tray. The dinner tray falls into the third recycling box through the guide member.
The housing is further provided with a chopstick and spoon collection opening 40, configured to place chopsticks and spoons, thereby enriching functions of the entire recycling device and providing convenience for a user.
The working method of the automatic dinner tray recycling device in this embodiment is that as shown in FIG. 17, a user places a dinner tray into the placing tray. Under the action of the first motor, the sheave, and the rotational frame, the dinner tray enters the dumping region. Before the dinner tray enters the dumping region, the first infrared sensor senses ray information from the first infrared emitter in the housing. The controller is used to control the second motor to work. The second motor drives, through the lead screw, the lifting frame to move. The compression hook compresses the dinner tray. The rotational frame continues to rotate. With the engagement of the first gear and the second gear, the first gear rotates to drive the frame to slide along the track member and rotate with the cooperation between the bump and the sliding groove. Leftovers and the little bowl in the dinner tray fall onto the conveying mesh belt of the mesh belt conveying mechanism. The leftovers fall into the first recycling box through cracks of the conveying mesh belt. The little bowl falls into the second recycling box with the transmission of the conveying mesh belt. At the same time, the brush cleans the surface of the dinner tray. The rotational frame continues to rotate. The placing tray drives the dinner tray to move to a position above the third recycling box. In this case, the second infrared sensor senses ray information from the second infrared emitter, and sends an instruction to the controller. The controller controls the second motor to work. The second motor drives the clamping mechanism to loosen the dinner tray. The dinner tray falls into the third recycling box through the guide member under gravity, to implement dinner tray recycling. The rotational frame continues to rotate. Under the action of the first gear and the crank, the frame slides along the track member along an opposite direction. The bump slides in the sliding groove in an opposite direction. The placing tray overturns 1800 and then enters the tray-receiving region for dinner tray placement.
In this embodiment, the sliding groove includes two linear sliding grooves that can maintain the placing tray upward or downward for a certain time, thereby facilitating maintenance of a state in which the placing tray faces downward when rotating in the dumping region and the recycling region, and facilitating maintenance of a state in which the placing tray faces upward when moving in the tray-receiving region.
Use of the dinner tray recycling device in this embodiment can recycle the dinner tray and the little bowl separately. The entire process is performed automatically, improving the working efficiency and reducing the workload of staff. Besides, the clamping mechanism is controlled by using the infrared sensor and the infrared emitter, so that the control precision is high and the stability is good.
The specific implementations of the present invention are described above with reference to the accompanying drawings, but are not intended to limit the protection scope of the present invention. Those skilled in the art should understand that various modifications or deformations may be made without creative efforts based on the technical solutions of the present invention, and such modifications or deformations shall fall within the protection scope of the present invention.
