[0017] The beneficial effects of the present invention are:

[0018] 1. The plate can be automatically recycled throughout the whole process, reducing the tediousness and congestion caused by manual plate collection, improving work efficiency and working environment. Diners can directly place plates on the plate rack after eating. When the plate conveyor rack assembly is full of plates, the plate rack is driven to flip toward the kitchen waste collection bucket by the flip drive mechanism, and the remaining food on the plate is poured into the kitchen waste collection bucket, and then the plate rack is driven to reset, and then the roller conveyor is started for conveying, so that the fully loaded plate conveyor rack assembly can be transported from the dining area to the cleaning room for unified cleaning;

When pouring out the remaining food on the plate, the protruding teeth of the lifting frames on both sides are inserted into the gaps between the outriggers one by one, and the driving motors of the two flip driving mechanisms are simultaneously actuated to drive the lifting frames to move in the vertical direction, wherein the lifting frame close to the kitchen waste collection barrel vertically descends, and the lifting frame far from the kitchen waste collection barrel vertically rises, so that all the plate placement racks can be tilted toward the kitchen waste collection barrel at the same time, and the plate limit ends are used to support the plate to prevent the plate from sliding down, and the remaining food on the plate will fall onto the guide plate due to its own weight, and then fall into the kitchen waste collection barrel;

[0020] 3. After pouring out the residual food on the plate, the plate placement rack is driven to reset by the overturning drive mechanism, and then the roller conveyor is started to move the plate conveying rack assembly to the cleaning room with the plate. Since the protruding teeth on the lifting rack are inserted into the gaps between the outriggers one by one, it is equivalent to the protruding teeth on the lifting rack and all the outriggers being arranged alternately. With such a structural setting, the protruding teeth on the lifting rack can easily drive all the outriggers to flip so that the plate is in an inclined state. With such a structural setting, all the outriggers can also be driven to rotate and reset. When the roller conveyor is used to drive the plate conveying rack assembly to move, the protruding teeth of the lifting rack can quickly detach from the outriggers and do not interfere with the movement of the plate conveying rack assembly. Therefore, after pouring out the residual food on the plate, the overturning drive mechanism will not interfere with the conveying movement of the plate conveying rack assembly.

[0028] The following is combined with Figure 1-7 The present invention is further illustrated with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-7 As shown, a canteen plate cleaning and recycling device comprises:

[0030] Roller conveyor 1, whose conveying start end is located in the dining area and whose conveying end end is located in the cleaning room;

[0031] The meal tray conveyor assembly 2 is placed on the roller conveyor 1 and is used to collect meal trays 7;

[0032] Among them, Figure 3 As shown, the meal tray conveyor rack assembly 2 includes an outer frame 201, and a plurality of meal tray racks 202 for placing meal trays 7 that are connected to the outer frame 201 in an upside-down manner, and the meal tray racks 202 are arranged in sequence from top to bottom.

[0033] The conveying starting end of the roller conveyor 1 is provided with a flipping drive mechanism 3 and a kitchen waste collection bucket 5. The flipping drive mechanism 3 is used to drive the dinner plate placement rack 202 to rotate to an inclined state so that the residual food on the dinner plate 7 can be poured into the kitchen waste collection bucket 5.

[0034] like Figure 7 As shown, in order to make the movement of the meal tray conveying rack assembly 2 have good guidance, a pair of side track plates 6 extending along the conveying track are installed on the roller conveyor 1, and the meal tray conveying rack assembly 2 is located as a whole between the two side track plates 6, and both sides of the outer frame 201 are rotatably connected with rollers 204. During transportation, the two rollers 204 of the outer frame 201 respectively roll with the two side track plates 6.

[0035] like Figure 1 As shown, in order to facilitate the recovery of leftover food, a guide plate 4 tilted downward toward the kitchen waste collection bucket 5 is installed at the conveying starting end of the roller conveyor 1 to guide the leftover food on the dinner plate 7 into the kitchen waste collection bucket 5.

[0036] When in use, diners can place the plates 7 directly on the plate rack 202 after eating. After the plates 7 are full of the plate conveyor rack assembly 2, the flip drive mechanism 3 is used to drive the plate rack 202 to flip toward the kitchen waste collection bin 5, and the remaining food on the plates 7 is poured into the kitchen waste collection bin 5. The plate rack 202 is then driven to reset, and then the roller conveyor 1 is started for conveying, so that the fully loaded plate conveyor rack assembly 2 can be transported from the dining area to the cleaning room for unified cleaning.

[0037] like Figure 3 As shown, each plate placement rack 202 is provided with two plate placement slots 202a for placing plates 7 side by side, and a plurality of plate placement slots 202a can be arranged side by side.

[0038] like Figure 3 , 5As shown, each plate rack 202 is provided with a horizontally extending flip axis 202b, and the outer frame 201 is configured as a front-to-back through-structure. The plate rack 202 is connected to the front-to-back through-channel of the outer frame 201 by flipping upside down through the corresponding flip axis 202b, so as not to interfere with the placing process of the plate 7. The connection point between the flip axis 202b and the plate rack 202 is in the middle of the plate rack 202, so as to better support the plate 7.

[0039] like Figure 5 , 6 As shown, the insertion side of each plate placement slot 202a is configured as an open structure, and the pouring side of each plate placement slot 202a is provided with a plate limiting end 202c for preventing the plate 7 from sliding off when pouring. The plate limiting end 202c has a C-shaped groove for accommodating the insertion of the plate 7. The plate limiting end 202c is at the lowest position of the plate placement slot 202a when pouring, thereby preventing the plate 7 from sliding off when pouring the remaining food.

[0040] The above-mentioned flip shafts 202b are arranged in a vertical row from top to bottom, each flip shaft 202b is equipped with an outrigger 203, and the middle part of the outrigger 203 is connected to the flip shaft 202b, all the outriggers 203 are arranged in a vertical row from top to bottom, and a pair of flip driving mechanisms 3 are arranged, and when the remaining food on the dinner plate 7 is dumped, the two ends of the outrigger 203 are respectively arranged to transmit the transmission to cooperate with the outrigger 203.

[0041] like Figure 3 , 5 As shown, the above-mentioned flip driving mechanism 3 includes a fixed main body seat 301, and a lifting frame 305 installed on the main body seat 301 for vertical lifting and movement. A lifting driving component for driving the lifting frame 305 to perform lifting and movement is installed on the main body seat 301. A plurality of convex teeth 305b protruding horizontally toward the outrigger 203 are provided on the lifting frame 305 on the side facing the outrigger 203 to form a comb-tooth structure; when dumping the remaining food on the dining plate 7, the convex teeth 305b on each lifting frame 305 are inserted into the gap between the outriggers 203 one by one, and the lifting frame 305 close to the food waste collection bucket 5 is lower than the lifting frame 305 away from the food waste collection bucket 5.

[0042] like Figure 4 , 5As shown, the lifting drive assembly includes a driving motor 302, a transmission connecting rod 303, and an inner movable block 304. The lifting frame 305 is provided with a rectangular transverse movable cavity 305a, the long side of which extends horizontally. The driving motor 302 is mounted on the main body seat 301, and the inner movable block 304 is movably mounted in the transverse movable cavity 305a and is movably arranged horizontally along the long side of the transverse movable cavity 305a. One end of the transmission connecting rod 303 is rotatably connected to the main shaft of the driving motor 302, and the other end of the transmission connecting rod 303 is rotatably connected to the inner movable block 304. When the driving motor 302 outputs power, the transmission connecting rod 303 performs a rotational motion, and the inner movable block 304 is driven by the transmission connecting rod 303. The inner movable block 304 pushes the lifting frame 305 upward or downward, and the inner movable block 304 performs horizontal motion in the transverse movable cavity 305a.

[0043] When dumping the remaining food on the dinner plate 7, the protruding teeth 305b of the lifting frames 305 on both sides are inserted into the gaps between the outriggers 203 one by one, and the driving motors 302 of the two flip driving mechanisms 3 are simultaneously actuated to drive the lifting frames 305 to move in the vertical direction, wherein the lifting frames 305 close to the food waste collection bucket 5 vertically descend, and the lifting frames 305 away from the food waste collection bucket 5 vertically rise, so that all the dinner plate placement racks 202 can be tilted toward the food waste collection bucket 5 at the same time, such as Figure 6 As shown, the plate limiting end 202 c is used to support the plate 7 to prevent the plate 7 from sliding downward, and the remaining food on the plate 7 will fall onto the guide plate 4 due to its own weight, and then fall into the kitchen waste collection bucket 5.

[0044] Since the protruding teeth 305b on the lifting frame 305 are inserted into the gaps between the outriggers 203 one by one, it is equivalent to that the protruding teeth 305b on the lifting frame 305 are alternately arranged with all the outriggers 203. With such a structural arrangement, the protruding teeth 305b on the lifting frame 305 can easily drive all the outriggers 203 to flip over, so that the dining plate 7 is in a tilted state. With such a structural arrangement, all the outriggers 203 can also be driven to rotate and reset. When the roller conveyor 1 is used to drive the dining plate conveying rack assembly 2 to move, the protruding teeth 305b of the lifting frame 305 can quickly break away from the outriggers 203 and do not interfere with the movement of the dining plate conveying rack assembly 2. Therefore, after pouring out the remaining food on the dining plate 7, the flipping drive mechanism 3 will not interfere with the conveying movement of the dining plate conveying rack assembly 2.

[0045] The above are preferred embodiments of the present invention. A person skilled in the art may make various changes or improvements on this basis. Without departing from the general concept of the present invention, these changes or improvements should fall within the scope of protection required by the present invention.
