The rice receiving component 333 is connected to the meal preparation and conveying device 100, and then the rice receiving component 333 can convey the rice grains to the lunch box carried by the meal preparation and conveying device 100, thereby realizing the quantitative conveying of the rice grains. This structure has been simplified, and the quantitative component 332 can accurately configure the conveying amount each time, thereby ensuring accuracy.

[0112] Furthermore, the quantitative component 332 includes two measuring cup components 3321 respectively arranged at the two ends of the quantitative connecting plate 331; the two measuring cup components 3321 have the same structure and both include a measuring cup pushing plate 33211, a measuring cup pushing cylinder 33212 and two rice receiving measuring cups 33213, the two measuring cup pushing plates 33211 are respectively movably arranged at the two ends of the quantitative connecting plate 331, the two measuring cup pushing cylinders 33212 are respectively driven and connected to the two measuring cup pushing plates 33211, and the two rice receiving measuring cups 33213 are provided at the bottom of the same measuring cup pushing plate 33211. Specifically, when the two measuring cup pushing cylinders 33212 drive the two measuring cup pushing plates 33211 to move, the four rice receiving measuring cups 33213 can respectively correspond to the four discharge holes on the quantitative connecting plate 331, so that the rice grains in the hopper 320 can be filled in the rice receiving measuring cups 33213. After filling, the two measuring cup pushing cylinders 33212 drive the two measuring cup pushing plates 33211 to move. At this time, moving the four rice receiving measuring cups 33213 to the position of the rice receiving assembly 333 can realize the function of quantitative feeding.

[0113] Furthermore, the rice receiving assembly 333 includes two rice blocking plates 3331 and four rice receiving barrels 3332; the two rice blocking plates 3331 are respectively abutted against the four rice receiving measuring cups 33213, and the four rice receiving barrels 3332 are respectively arranged at the bottom of the two rice blocking plates 3331, and the four rice receiving measuring cups 33213 are respectively movably connected to the four rice receiving barrels 3332 for feeding or stopping feeding. Specifically, after the rice grains in the hopper 320 are quantitatively loaded into the four rice-receiving measuring cups 33213, the two measuring cup pushing cylinders 33212 will drive the two measuring cup pushing plates 33211 to move, and then the two measuring cup pushing plates 33211 will drive the four rice-receiving measuring cups 33213 to the positions of the four rice-receiving barrels 3332. In this way, the rice grains in the four rice-receiving measuring cups 33213 can be transported into the four rice-receiving barrels 3332, and then output to the outside world by the four rice-receiving barrels 3332, thereby achieving a precise quantitative feeding function. In addition, when the two measuring cup pushing plates 33211 drive the four rice-receiving measuring cups 33213 to approach the four rice-receiving barrels 3332, the two rice blocking plates 3331 will cover the bottoms of the four rice-receiving measuring cups 33213, preventing the four rice-receiving measuring cups 33213 from leaking during movement, thereby ensuring accuracy.

[0114] In another embodiment of the present invention, Figure 4 As shown, the automatic quantitative water injection mechanism 400 includes:

[0115] The water injection frame 410 and the water injection assembly 420 are mounted on the meal preparation and conveying device 100.

[0116] At least one water injection assembly 420, at least one water injection assembly 420 is provided on the water injection frame 410 for quantitatively injecting water into the lunch box carried by the meal preparation and conveying device 100;

[0117] When there are two water injection assemblies 420, both of the water injection assemblies 420 are arranged on the water injection rack 410, and both of the water injection assemblies 420 are arranged at the same horizontal position on the water injection rack 410, and the water outlet directions of the two water injection assemblies 420 are the same.

[0118] Specifically, in this embodiment, when the lunch box carried by the meal preparation and conveying device 100 is conveyed to the bottom of the water injection component 420, the water injection component 420 will quantitatively inject water to complete the function of automatic quantitative water injection. When the number of the water injection components 420 is two, the water injection components 420 are arranged at both ends of the water injection components 420, which is conducive to evenly conveying water. The water outlet directions of the two water injection components 420 are the same, which is conducive to the device to evenly convey water in the same direction and reduce the error in the water delivery amount.

[0119] Furthermore, the water injection assembly 420 includes a water injection fixing seat 430, a water inlet part 440, a water flow switch 450, and a water control unit 460; the water injection fixing seat 430 is fixedly connected to the water injection frame 410, the water inlet part 440 is arranged in the water injection fixing seat 430, and the water inlet part 440 is provided with an internal hollow water inlet cavity for inputting water source, the water control unit 460 is connected to the water inlet cavity and is used to output the water source in the water inlet cavity, and the water flow switch 450 is provided on the output end of the water inlet part 440. Specifically, a water flow switch 450 is provided between the water inlet part 440 and the water control unit 460. The water flow switch 450 can control whether the water flow can enter the water control unit 460. When the water flow switch 450 is turned on, the water flows into the water control unit 460 from the water inlet cavity. Then, the water source in the water inlet cavity can be squeezed through the water control unit 460 and output to the lunch box carried by the meal preparation and conveying device 100, thereby performing an automatic quantitative water injection function.

[0120] Furthermore, the water control unit 460 includes two water control modules 470, and the two water control modules 470 are respectively arranged on both sides of the output end of the water inlet part 440, and the two water control modules 470 are both connected to the water inlet chamber. The two water control modules 470 have the same structure and both include a water storage pipe 471, a piston, a water control cylinder 472 and a nozzle 473. The two water storage pipes 471 are each provided with a water storage chamber for storing water, and the two water storage chambers are both connected to the water inlet chamber. The two pistons are respectively arranged in the two water storage chambers, and the two water control cylinders 472 are respectively arranged at one end of the two water storage chambers. The piston rods of the two water control cylinders 472 are respectively driven and connected to the two pistons, and the two nozzles 473 are respectively arranged at the other end of the two water storage chambers. Specifically, when the water control cylinder 472 is working, the piston rod of the water control cylinder 472 can drive the piston to move, so that the piston can press out the water in the water storage pipe 471. A nozzle 473 is installed in the direction in which the water is pressed out, so that the water will be sprayed out from the nozzle 473 to achieve precise water spraying.

[0121] In another embodiment of the present invention, Figure 5 As shown, the double-station meal tray packing device 800 includes:

[0122] The tray stacking mechanism 810 is provided in two groups, and the two groups of the tray stacking mechanisms 810 are arranged at intervals and opposite to each other; the two groups of the tray stacking mechanisms 810 are used to stack the trays and load them into the steamer;

[0123] And a plate transfer mechanism 820 , the first and second ends of which are respectively fixed on the two groups of the plate stacking mechanisms 810 , and the plate transfer mechanism 820 is used to transfer the plates to each of the plate stacking mechanisms 810 .

[0124] Specifically, in this embodiment, when the dual-station tray packing device 800 is in use, the tray transfer mechanism 820 transfers trays carried by the meal preparation conveyor device 100 to any one of the tray stacking mechanisms 810. Once the trays on the tray stacking mechanisms 810 have reached a certain number of layers, they are boxed and transported away. During the boxing and transport process, the tray transfer mechanism 820 continues to transfer trays carried by the meal preparation conveyor device 100 to another set of tray stacking mechanisms 810. In this way, the two sets of tray stacking mechanisms 810 operate alternately, reducing the time required to wait for the steamer to be transported away and back, thereby improving tray packing efficiency.

[0125] Furthermore, each of the plate stacking mechanisms 810 includes a stacking frame 811, a stacking lifting support platform 812, and a stacking lifting drive assembly 813; the stacking lifting support platform 812 is slidably connected to the stacking frame 811; the stacking lifting drive assembly 813 is fixed to the stacking frame 811; the first and second ends of the plate transfer mechanism 820 are respectively fixed to the two stacking frames 811; the stacking lifting drive assembly 813 is drivably connected to the stacking lifting support platform 812 so that the stacking lifting support platform 812 performs linear reciprocating motion in the vertical direction; wherein the plate transfer mechanism 820 transfers the plate to the stacking lifting support platform 812. Specifically, the stacking lifting drive assembly 813 has a movable end that can perform linear reciprocating motion in the vertical direction, and the stacking lifting support platform 812 is detachably mounted on the movable end. The tray transfer mechanism 820 transfers the first tray to the stacking lift support platform 812. At this point, the movable end of the stacking lift drive assembly 813 moves, thereby driving the stacking lift support platform 812 and the trays thereon vertically downward by a predetermined distance. This distance should be no less than the height of the trays to ensure that the next tray can be stably placed on top of the trays on the top layer. In this way, by driving the stacking lift support platform 812 to move vertically, the trays move in a horizontal linear motion during transfer, reducing their shaking during transfer and improving the accuracy of plate placement.

[0126] Furthermore, the plate transfer mechanism 820 includes a plate grabbing fixture 821 and a plate moving assembly 822; the plate grabbing fixture 821 is used to clamp and place plates; the first and second ends of the plate moving assembly 822 are respectively fixed to the two sets of the plate stacking mechanisms 810; the plate moving assembly 822 is drivingly connected to the plate grabbing fixture 821 to move the plate grabbing fixture 821 toward the plate stacking mechanisms 810 and place the plates on the plate stacking mechanisms 810. Specifically, the movable end of the plate moving assembly 822 moves, thereby driving the plate grabbing fixture 821 thereon to move. When the plate grabbing fixture 821 reaches the meal preparation conveying device 100, the movable end of the plate moving assembly 822 stops moving, causing the plate grabbing fixture 821 to also stop moving. At this time, the plate grabbing fixture 821 clamps the plate, and then the movable end of the plate moving assembly 822 moves, thereby driving the plate grabbing fixture 821 and the plate thereon to move toward any set of the plate stacking mechanisms 810. When the plate grabbing fixture 821 reaches another predetermined position, the movable end of the plate moving assembly 822 stops moving, causing the plate grabbing fixture 821 to also stop moving. At this time, the plate grabbing fixture 821 places the plate on the plate stacking mechanism 810. In this way, automated plate handling is achieved, freeing up a lot of labor.

[0127] In addition, if Figure 6 As shown, the stacking lift support platform 812 includes a stacking slide assembly 8121 and a stacking lift support plate 8122 for supporting the dining plates; the stacking slide assembly 8121 is slidably connected to the stacking frame 811; the stacking slide assembly 8121 is provided with at least one group; the output end of the stacking lift drive assembly 813 is fixedly connected to the stacking slide assembly 8121; the stacking lift support plate 8122 is detachably connected to the stacking slide assembly 8121; wherein, the output end of the stacking lift drive assembly 813 drives the stacking slide assembly 8121, thereby causing the stacking lift support plate 8122 to move in the vertical direction. Specifically, by providing two groups of the stacking slide assemblies 8121, the stability of the stacking lift support plate 8122 during movement can be improved.

[0132] And a box cover feeding assembly 940, which is arranged on the top of the box cover positioning assembly 930, and covers the box cover located at the output end of the box cover loading assembly 920 on the steamer supported by the meal preparation and conveying device 100.

[0133] Specifically, in this embodiment, when the box cover transfer, positioning and covering mechanism 900 is working: the box cover loading component 920 conveys the box cover toward the meal preparation and conveying device 100, and when the box cover is conveyed to the output end of the box cover loading component 920, the box cover positioning component 930 will position the box cover at the current position and adjust the position of the box cover. Finally, the box cover feeding component 940 moves to the top of the box cover, and the box cover feeding component 940 clamps and covers the box cover on the steamer carried by the meal preparation and conveying device 100 to obtain a sealed steamer as a whole, thereby realizing automatic loading of the box cover.

The lid positioning bar 931 is connected to the output end of the lid positioning drive unit 932 and is used to position the lid passing through the output end of the lid loading assembly 920. Specifically, when the lid reaches the output end of the lid loading assembly 920, the lid positioning drive unit 932 drives the lid positioning bar 931 to tighten the lid, preventing it from moving further. At this time, the lid feeding assembly 940 can easily pick up the lid.

[0135] Furthermore, the lid feeding assembly 940 includes a lid feeding connection plate 941, a lid feeding robot 942, and a lid feeding drive unit 943; the lid feeding connection plate 941 is disposed on the top of the lid positioning assembly 930, the lid feeding robot 942 is disposed on a linear path of the lid feeding connection plate 941, and the lid feeding drive unit 943 is disposed on the lid feeding connection plate 941 and connected to the lid feeding robot 942 to drive the lid feeding robot 942 to move. Specifically, the lid feeding drive unit 943 drives the lid feeding robot 942 to move along the length direction of the lid feeding connection plate 941 to the top of the lid. After clamping the lid, the lid feeding drive unit 943 drives the lid feeding robot 942 to move again along the length direction of the lid feeding connection plate 941 to the meal preparation conveying device 100 to unload the meal.

[0136] In another embodiment of the present invention, Figure 8 As shown, the flow-type electromagnetic heating device 1100 includes:

[0137] Heating rack 1110;

Thus, the mobile electromagnetic heating device of the present invention utilizes electromagnetic induction to heat the meal placed on the plates within the steamer. Specifically, the electromagnetic heating assembly 1130 generates an alternating magnetic field. When a plate passes over it, the plate surface cuts through the alternating magnetic field lines, generating alternating currents (i.e., eddy currents) in the metal portion of the plate's bottom. The eddy currents cause charge carriers at the plate's bottom to move at high speed and irregularly. The charge carriers collide and rub against atoms, generating heat energy, thereby heating the meal.

[0141] Furthermore, the electromagnetic heating assembly 1130 includes multiple electromagnetic induction heating modules 1140; these modules are mounted on the heating frame 1110 and arranged side by side at the center of the steamer transport assembly 1120 along the conveying direction of the steamer transport assembly 1120. The modules 1140 are independently configured and controlled. Specifically, the modules 1140 are evenly distributed along the conveying direction of the steamer transport assembly 1120, ensuring that the food on the trays is evenly heated during transport. This allows the food on the trays to be heated while being transported through the steamer, significantly improving production efficiency.

[0142] Furthermore, the multiple electromagnetic induction heating modules 1140 have the same structure, each comprising an induction cooker body 1141 and a frequency modulation module 1142. The induction cooker body 1141 is mounted on the upper surface of the heating frame 1110 and positioned in the center of the steamer transport assembly 1120. The induction cooker body 1141 and the food contained in the metal container are placed on opposite sides of the steamer. The frequency modulation module 1142 is mounted on the side of the heating frame 1110 and electrically connected to the induction cooker body 1141, and is used to adjust the frequency of the electromagnetic waves emitted by the induction cooker body 1141. Specifically, the induction cooker body 1141 generates an alternating magnetic field, which induction heats the steamer and the food tray, preventing damage to the induction cooker body 1141 due to long-term heat. Furthermore, by providing the frequency modulation module 1142 with a high-frequency signal to excite the high-frequency magnetic field within the induction cooker body 1141, the induction distance is extended, providing greater freedom of movement.

[0146] And a lifting drive component 1230, which is respectively connected to the reversing conveying component 1220 and the fixed installation base 1210, and is used to drive the two ends of the reversing conveying component 1220 to push out of the upper surface of the steamer conveying line 700, so that the steamer is separated from the steamer conveying line 700.

[0147] Specifically, in this embodiment, the steamer lifting and reversing conveying mechanism 1200 can realize the steamer reversing at the end of the steamer conveying line 700 and transitioning smoothly to the meal preparation conveying device 100; during the transition process, the lifting drive component 1230 is set to drive the two ends of the reversing conveying component 1220 to be pushed out of the upper surface of the steamer conveying line 700, so that the steamer is separated from the steamer conveying line 700; then the two ends of the reversing conveying component 1220 rise and pass through the conveying gap of the steamer conveying line 700 to carry the steamer and convey it to the meal preparation conveying device 100; because the conveying direction of the reversing conveying component 1220 is on the same straight line as the conveying direction of the meal preparation conveying device 100, the steamer can be quickly and smoothly transferred from the end of the steamer conveying line 700 to the meal preparation conveying device 100, shortening the conveying time and improving the conveying efficiency of the steamer.
