[0049] In one embodiment, the first drive device 35, the second drive device 18 and the third drive device 43 are preferably servo motors, but are not limited thereto. The fourth drive device 48 is preferably a cylinder, but is not limited thereto.

[0050] In one embodiment, the workflow and structural design principles of the food loading and unloading conveyor line are as follows: By designing the structure of the dual-chain feed line 3, the dual-chain feed line 3 simultaneously loads and conveys two parallel groups of food, thereby improving the efficiency of food loading and conveying. The first drive device 35 of the dual-chain feed line 3 drives the first sprocket assembly 5 and the second sprocket assembly 6 in a synchronous and circular transmission. The first sprocket assembly 5 and the second sprocket assembly 6 respectively use their respective paddles 54 to pry the food placed in front of them for conveyance. The first side guide plate 57 and the first middle guide plate 56 guide and limit the food conveyed on the first sprocket assembly 5, and the second side guide plate 58 and the first middle guide plate 56 guide and limit the food conveyed on the second sprocket assembly 6, thereby ensuring the high precision of the synchronous conveyance of the two groups of food.

[0051] It is achieved by respectively providing a first tensioning assembly 7 and a second tensioning assembly 8 on the inner side of each feed side mounting plate 32, and the chains 53 of the first sprocket assembly 5 and the second sprocket assembly 6 are vertically tensioned by the first tensioning assembly 7 on the same side thereof, and the vertical tensioning wheel 71 is fixed on the vertical guide groove 34 by adjusting the vertical positioning piece 72 to adjust the tightness of the chains 53 of the first sprocket assembly 5 and the second sprocket assembly 6; the chains 53 of the first sprocket assembly 5 and the second sprocket assembly 6 are transversely tensioned by the second tensioning assembly 8 on the same side thereof, and the transverse tensioning wheel 81 is fixed on the transverse guide groove 33 by adjusting the transverse positioning piece 82 to adjust the tightness of the chains 53 of the first sprocket assembly 5 and the second sprocket assembly 6.

[0052] The first inner tray conveyor line 1 and the second inner tray conveyor line 2 receive and convey the inner trays respectively. The first inner tray conveyor line 1 and the second inner tray conveyor line 2 are respectively docked with the previous station through their respective inner tray receiving covers 12 to receive the inner trays transmitted from the previous station; when the inner tray falls onto the inner tray conveyor belt 11 through the receiving hole in the inner tray receiving cover 12, the inner tray conveyor belt 11 is driven by the second driving device 18 to rotate to convey the inner tray, and the third side guide plate 14 in the first inner tray conveyor line 1 and the second inner tray conveyor line 2 is docked with the third side guide plate 14 in the first inner tray conveyor line 1 and the second inner tray conveyor line 2. The four side guide plates 15 limit and guide the inner trays transported on the inner tray conveyor belt 11 to ensure high conveying accuracy of the inner trays; the guide plate positioning parts 16 position, adjust and fix the third side guide plate 14 and the fourth side guide plate 15. Each inner tray conveyor line is connected and installed with the double chain feeding line 3 and the inner tray loading and unloading line 4 through two connecting plates 101 respectively, so that the inner trays can be transported and loaded synchronously from two different directions through the first inner tray conveyor line 1 and the second inner tray conveyor line 2 to ensure high loading and conveying efficiency of the inner trays.

[0053] The structure of the box loading and unloading mechanism 9 is designed. The lever 404 of the box loading and unloading mechanism 9 is installed on the mounting base plate 401 through the lever mounting plate 405. The third drive device 43 drives the movable base plate 49 to move horizontally on the linear sliding module 42. Since the guide rod and guide sleeve assembly 47 and the fourth drive device 48 are fixedly mounted on the sliding part 46 of the linear sliding module 42, the fourth drive device 48 drives the movable base plate 49 to move up and down on the guide rod and guide sleeve assembly 47. When the movable base plate 49 moves up and down, it can drive multiple lever plates 403 to move up and down synchronously through the mounting base plate 401. When the first inner tray conveyor line 1 and the second inner tray conveyor line 2 respectively convey the inner trays to the box loading and unloading mechanism 9 in the inner tray loading and unloading line 4, they can catch the food dropped by the paddle 54 of the double-chain feeding line 3 to complete the automatic loading of food into the inner trays. At the same time, the fourth driving device 48 drives the two driving rods 404 of each paddle plate 403 to synchronously upwardly penetrate the inner tray loading double channels 409 and respectively emerge from between the fifth side guide plate 407 and the second middle guide plate 406 and from between the second middle guide plate 406 and the sixth side guide plate 408. The two exposed driving rods 404 are respectively located at the rear sides of the two inner trays loaded with food that are conveyed in parallel or in parallel. Then, the third driving device 43 drives the moving bottom plate 49 to drive the two relatively arranged driving rods 404 to move horizontally to push the two parallel or parallel inner trays to move synchronously. The fourth drive device 48 drives the two shifting rods 404 of each shifting plate 403 to synchronously descend from between the fifth side guide plate 407 and the second middle guide plate 406 and from between the second middle guide plate 406 and the sixth side guide plate 408 and exit the inner tray loading double channel 409. The third drive device 43 cooperates with the fourth drive device 48 to drive the two shifting rods 404 of each shifting plate to synchronously retreat and then rise to the rear side of the next pair of inner trays loaded with food. The third drive device 43 drives the shifting rod 404 to move forward (i.e., move away from the double-chain feeding line 3) according to the aforementioned method to convey the next inner tray. This cycle is repeated so that the two sets of inner trays loaded with food can be automatically conveyed and discharged synchronously in sequence through the inner tray loading and unloading line 4.

[0054] Its overall structural design realizes a series of operations such as automatic loading and conveying of two groups of food simultaneously, automatic loading and conveying of two groups of inner trays simultaneously, automatic loading and conveying of the two groups of loaded food into the inner trays simultaneously, and automatic unloading and conveying of the two groups of inner trays with loaded food simultaneously on one device, and the above series of operations do not require manual participation. It not only has the advantages of high food conveying efficiency, high food conveying precision, high inner tray conveying efficiency, high inner tray conveying precision, high inner tray loading efficiency, high inner tray loading precision, high inner tray unloading efficiency and high inner tray unloading precision, it also realizes automated operation, so that it can effectively solve the problems that most food production plants on the market currently generally use manual loading of food into the inner trays, which results in low work efficiency, high labor intensity of workers, high labor costs of enterprises and inability to meet the requirements of enterprise automated production.

Any technical solution that is identical or equivalent to the content described in the claims of the present invention should be included in the protection scope of the present invention.
