[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Example 1, reference Figure 1-3 , a smart packaging device for food production, comprising a conveyor frame 1 equipped with a metal conveyor belt 2 and a packaging actuator;

[0040] In this embodiment, a fixing plate 3 is welded to the top outer wall of the conveyor frame 1, an infrared sensor 4 is fixedly installed on the side wall of the fixing plate 3, and an industrial computer 5 is fixedly installed on the front outer wall of the fixing plate 3;

[0041] In this embodiment, the packaging actuator includes an actuator cylinder 6 fixedly mounted on the top outer wall of the fixed plate 3, an air storage box 7 fixedly connected to the bottom end of the piston rod of the actuator cylinder 6, an air bag body 8 sealed and fixedly connected to the air storage box 7 and filled with air, an air bag nozzle 9 provided at the top of the air bag body 8, a spring telescopic rod 10 fixedly connected to the top inner wall of the air storage box 7, and a rubber piston plate 11 fixedly connected to the bottom end of the spring telescopic rod 10;

[0042] Furthermore, an air leakage hole 12 is provided on the airbag mouth 9, a rubber piston plate 11 is adapted to the airbag mouth 9 and is located below the air leakage hole 12, the rubber piston plate 11 is sealingly and slidingly connected to the airbag mouth 9, the air storage box 7 is connected to the airbag body 8 through an inflation pipe 13, an electromagnetic inflation valve 14 is installed on the inflation pipe 13, and the electromagnetic inflation valve 14, the actuator cylinder 6 and the infrared sensor 4 are all electrically connected to the industrial computer 5;

[0043] When the present embodiment is working: first, when the infrared sensor 4 detects that the food to be packaged enters, it transmits the entry signal to the industrial computer 5, which controls the execution cylinder 6 and the electromagnetic inflation valve 14 to work, that is, the execution cylinder 6 controls the air bag 8 at the bottom of the air storage box 7 to move downward;

[0044] Secondly, when the airbag 8 squeezes the packaging film outside the food, when the airbag 8 squeezes the packaging film downward and moves to contact the food, the food applies pressure to the airbag 8, and the gas in the airbag 8 squeezes the rubber piston plate 11 upward and compresses the spring telescopic rod 10. Then, when the rubber piston plate 11 is pressed above the air leakage hole 12, the squeezed gas will enter the air storage box 7 from the air leakage hole 12, which makes it convenient to package foods of different structural shapes. The packaging film can be closely attached to the food through the structural change of the airbag 8 after being stressed, and the excess air is discharged, thereby improving the effect of sealing the food packaging.

[0045] Finally, the execution cylinder 6 controls the air storage box 7 to move upward so that the airbag 8 gradually moves upward and leaves the food. At this time, the squeezing force of the food on the airbag 8 gradually disappears. Then the spring telescopic rod 10 will drive the rubber piston plate 11 to return to its original position, and then the rubber piston rod 11 will move again to the bottom of the air leakage hole 12 for sealing. Then the electromagnetic inflation valve 14 will automatically open to fill the gas stored in the air storage box 7 into the airbag 8, so as to facilitate the continuous extrusion packaging of subsequent foods, which is more convenient and efficient to use.

[0046] Example 2, reference Figure 1 and Figure 4-5 , This embodiment is optimized on the basis of embodiment 1, specifically: a smart packaging device for food production, further comprising an adjustable limiting mechanism;

[0047] In this embodiment, the adjustable limit mechanism includes two connecting rods 15 symmetrically inserted at the front end of the conveyor frame 1, two racks 16 fixedly connected to the bottom ends of the two connecting rods 15 in sequence, two limit bars 17 fixedly connected to the upper ends of the two connecting rods 15 in sequence, a servo motor 18 fixedly installed on the outer wall of the bottom of the conveyor frame 1, and a gear 19 fixedly sleeved on the output shaft of the servo motor 18;

[0048] Furthermore, the two racks 16 are symmetrical and staggered, and both racks 16 are meshed with the gear 19;

[0049] When the present embodiment is working, the gear 19 is controlled to rotate by the servo motor 18, and then the two racks 16 meshing with the gear 19 drive the two limit bars 17 connected to the two connecting rods 15 to make a centering movement, so that it is convenient to flexibly adjust the limit spacing of the two limit bars 17, and then limit the protection of foods of different sizes, so as to avoid the deviation of foods entering the packaging actuator, thereby helping to improve the quality of food packaging.

[0050] Example 3, reference Figure 1 and Figure 6-8 , This embodiment is optimized on the basis of embodiment 1, specifically: a smart packaging device for food production, further comprising an adjustable pneumatic sealing mechanism;

[0052] Furthermore, the outer walls of the two T-shaped adjusting rods 23 are slidably connected to the inner wall of the slide slot, and the two pneumatic sealing tools include two sealing cylinders 24 symmetrically fixed to the outer wall of the bottom of the T-shaped adjusting rod 23 and the same sealing knife 25 fixedly connected to the piston ends of the two sealing cylinders 24;

[0053] Furthermore, the control assembly includes a mounting frame 26 fixedly connected to the side wall of the support frame 20, a first stepper motor 27 fixedly mounted on the rear outer wall of the mounting frame 26, a driving bevel gear 28 fixedly mounted on the output shaft of the first stepper motor 27, and a driven bevel gear 29 fixedly mounted on one end of the bidirectional screw 22;

[0054] Furthermore, the output shaft of the first stepper motor 27 penetrates the mounting frame 26, the driving bevel gear 28 and the driven bevel gear 29 are meshed with each other, and the sealing cylinder 24, the first stepper motor 27 and the visual sensor 21 are all electrically connected to the industrial computer 5;

[0055] When this embodiment is working: after the initial packaging by the packaging actuator, the image signal of the initially packaged food is transmitted to the industrial computer 5 through the visual sensor 21, which analyzes and processes it and executes it through the first stepper motor 27. At this time, the bidirectional screw 22 is controlled by the first stepper motor 27 to rotate forward or reverse. Then, under the limit of the slide slot, the two T-shaped adjustment rods 23 threadedly connected to the bidirectional screw 22 will drive the two sealing knives 25 to move closer to or away from each other, so that the sealing distance between the two sealing knives 25 can be flexibly adjusted, which can adapt to the sealing requirements of different foods and improve the sealing effect of the food. Finally, the four sealing cylinders 24 control the two sealing knives 25 to move downward to complete the automatic sealing operation.
