[0045] The operation process of the bag taking and opening device for food packaging of the present invention is as follows:

[0046] Paper bag placement: According to the size of the paper bag, the limiting seat 92 is moved along the slide rail until the placement space between the limiting seat 92 and the paper bag placement seat 91 matches the target paper bag.

[0047] Bag taking: The slide 6 and the lifting and rotating mechanism 8 are moved by the belt transmission mechanism 7, and the height and rotation angle of the Y-shaped bracket 10 are adjusted by the lifting and rotating mechanism 8 until the material taking suction cup 11 at the lower end of the Y-shaped bracket 10 is in close contact with the paper bag in the paper bag bin 9, and then the paper bag is sucked by negative pressure. The servo motor 73 drives the transmission gear 75 to rotate through the driving wheel 74, the driven wheel 78 and the belt 79, and the transmission gear 75 drives the driven gear 76 to rotate through the toothed belt 77. The slide 6 is fixedly connected to the toothed belt 77, and then drives the slide 6 and the lifting and rotating mechanism 8 to move horizontally along the platform 5. After the slide 6 is moved to face the paper bag bin 9, the rotating motor 87 is started, and the rotating motor 87 drives the Y-shaped bracket 10 to rotate through the horizontal bar until the material taking suction cup 11 on the Y-shaped bracket 10 faces the paper bag in the paper bag bin 9. Then, the lifting motor 81 is started, and the lifting motor 81 drives the screw 84 to rotate through the second bevel gear 85 and the first bevel gear 86 that are meshed with each other, thereby driving the lifting platform 82 and the Y-shaped bracket 10 to move up and down until the material taking suction cup 11 at the lower end of the Y-shaped bracket 10 is in close contact with the paper bag in the paper bag bin 9, and then the negative pressure sucks the paper bag.

[0048] Bag opening: After taking the bag, the height and rotation angle of the Y-shaped bracket 10 are adjusted by the lifting and rotating mechanism 8, so that the paper bag adsorbed on the material taking suction cup 11 is facing the fixed suction cup 13, and then the slide 6 and the lifting and rotating mechanism 8 are driven by the belt transmission mechanism 7 to move toward the adjustment plate 12 until the other side of the paper bag is in close contact with the fixed suction cup 13, and then the paper bag is sucked by negative pressure. After the material taking suction cup 11 and the fixed suction cup 13 adsorb both sides of the paper bag respectively, the slide 6 and the lifting and rotating mechanism 8 are driven by the belt transmission mechanism 7 to move away from the adjustment plate 12, so as to open the paper bag, and the feeding port of the opened paper bag is facing the discharging port of the feeding guide groove 3.

[0049] Bagging: Food moves forward along the feeding conveyor belt 1, and the material sensor on one side of the push plate 44 senses whether there is material in front of the push plate 44 in real time. When the material is detected, the push motor 45 is started, and the push motor 45 drives the slider 42 to move forward and backward along the limit groove on the support plate 41 through the driving plate 46 and the transmission plate 47. The push rod 43 and the push plate 44 move synchronously with the slider 42, so that the food in front of the push plate 44 is pushed to the feeding guide groove 3, and then transferred into the opened paper bag, and then the adsorption force of the material suction cup 11 and the fixed suction cup 13 on the paper bag is cancelled, and the paper bag containing food moves to the next unit along the discharge conveyor belt 2. The cycle is repeated, and the food is packaged efficiently and hygienically.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the protection scope of the present invention.
