Of course, it can also be other devices with the same function, such as air cylinders.

[0024] During actual operation: First, connect the main power supply and signal line to the meal distribution machine, and press the start button on the control panel 350. At this time, the multifunctional meal lifter is in the standby state. When the meal purchaser selects the combined dinner plate 353 method for dining at the on-site table, such as Figure 3As shown in the figure, the food plate with the meals collected enters the area below the meal lifting device 328 through the meal conveyor belt inlet and outlet 351 of the meal conveyor belt 352. The moving device 328 adjusts the width of the meal lifting device 342 to suit the width of the plate when the plate has not arrived yet, i.e., when the meal purchaser selects the combined plate 353, and waits for the plate to come in. When the plate is in place, the meal lifting device sensor 331 drives the meal lifting motor 346 to work, and the meal lifting conveyor belt 344 rotates. At the same time, the plate card 347 holds the combined plate 353 and transports it upward. When it reaches the Linping meal outlet 305, the tray opening and closing sensor 322 senses and drives the large tray opening and closing device (motor) 326 to work, driving the front and rear large trays to close and lift the plate upward. After lifting it flat, the push rod driver (motor) 325 works to drive the plate push rod 323 to push the plate to the meal collection platform 340. The meal outlet door 306 opens, and the plate push rod 323 returns via the push rod slider 324, and the receiving tray descends, completing one working process.

[0025] When the meal purchaser selects the way to take away the square fast food box 354 for dining, as Figure 3 shown in the figure, the food plate with the meals collected also enters the area below the meal lifting device 328 through the meal conveyor belt inlet and outlet 351 of the meal conveyor belt 352. The moving device 328 reduces the width of the original combined plate 353 to suit the width of the food box when the plate has not arrived yet, i.e., when the meal purchaser selects the square fast food box 354. After the square fast food box 354 comes in, the plate card 347 holds the food box and transports it upward. When it reaches the Linping meal outlet 305, the tray opening and closing sensor 322 senses and drives the small tray opening and closing device (motor) 313 to work, driving the front and rear small trays to close and lift the plate upward. After lifting it flat, the push rod driver (motor) 325 works to drive the plate push rod 323 to push the plate to the meal collection platform 340. The meal outlet door 306 opens, and the plate push rod 323 returns via the push rod slider 324, and the receiving tray descends, completing one working process.

[0026] When the meal purchaser selects the way to take away the round soup and noodle box 355 for dining, as Figure 3 shown in the figure, the working steps of the meal lifter are the same as those of the square fast food box 354.

[0027] This unit works synchronously with the meal distribution unit, does not require staff to monitor the machine, and has the characteristics of a small body, low failure rate, and easy operation.

[0028] The above is the preferred implementation mode of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
