[0030] In one embodiment, the first transmission unit includes an upper separation plate electromagnet 11, an upper active separation plate connecting rod 12, an upper active separation plate push-pull rod 14, an upper active separation plate guide seat 15 and an upper active separation plate stopper 10; the upper active separation plate 23 is connected to the upper active separation plate push-pull rod 14 by screws; the upper active separation plate guide seat 15 is fixed to the active separation component mounting bracket 5, the upper active separation plate push-pull rod 14 passes through the D-shaped sleeve hole of the upper active separation plate guide seat 15 and is connected to the upper active separation plate connecting rod 12, the upper active separation plate connecting rod 12 is connected to the upper active separation plate stopper 10; the upper active separation plate stopper 10 is connected to the upper separation plate electromagnet 11. Please refer to Figure 4 In another embodiment, the upper active separation plate push-pull rod 14 and the upper active separation plate guide seat 15 are fitted with a D-shaped hole to prevent the upper active separation plate push-pull rod 14 from rotating. The upper active separation plate push-pull rod 14 is equipped with a compression spring 7 to make the upper active separation plate 23 generate a thrust in the direction of the lunch box to press the lunch box.

The upper active separation plate connecting rod 12 is installed on the active separation component mounting bracket 13 and can rotate in the horizontal direction. The upper separation plate electromagnet 11 contacts the upper active separation plate stopper 10, and the upper separation plate electromagnet 11 can generate thrust on the upper active separation plate stopper 10.

[0031] In one embodiment, the second transmission unit includes a lower active separation plate electromagnet 16 and a lower active separation plate guide seat 19; the lower active separation plate guide seat 19 is fixed to the active separation component mounting bracket 5, and the lower active separation plate 17 passes through the square sleeve hole of the lower active separation plate guide seat 19 and is connected to the lower active separation plate electromagnet 16 through the active pull rope screw 18. Please refer to Figure 5 In another embodiment, the lower active separation plate electromagnet 16 is connected to the lower active separation plate 17 through an active pull rope screw 18, and the lower active separation plate 17 and the lower separation baffle plate guide seat 19 are fitted with a square hole to ensure that 17 moves back and forth along the push-pull direction of the lower active separation plate electromagnet 16.

[0032] In one embodiment, the traction assembly includes a pull rope 4 and a plurality of guide wheels 20, the guide wheels 20 are mounted on the mounting base 2, the pull rope 4 is connected to the guide wheels 20, one end of the pull rope 4 is connected to the lower active separation plate 17 through the active pull rope screw 18; the other end of the pull rope is connected to the lower passive separation plate 28 through the passive pull rope screw 27. In another embodiment, the lower passive separation plate pressure plate 29 is connected to the passive separation assembly mounting seat 30 by screws, and the upper passive separation pressure plate 24 is fixed on the lower passive separation plate pressure plate 29. The lower passive separation plate 28 is mounted in a square groove of the passive separation assembly mounting seat 30, and is limited by the passive separation plate pressure plate 29, and can only move along the push-pull direction of the lower active separation plate electromagnet 16. The passive pull rope screw 27 is installed on the lower passive separation plate 28, and a tension spring 26 is installed on the passive pull rope screw 27. The other end of the tension spring 26 is connected to the tightening screw 25, and the tightening screw 25 is fixed on the upper passive separation pressure plate 24, so that the lower passive separation plate 28 always has a pulling force in the direction of the lunch box, thereby preventing the lowest lunch box from falling down.

[0033] In one embodiment, an upper limit column 3 for limiting the position of the lunch box is installed on the upper surface of the installation base plate 2 near the through hole structure; a lower limit column 6 for limiting the position of the lunch box is installed on the lower surface of the installation base plate 2 near the through hole structure.

[0034] In another embodiment, in the initial state, the upper active separation pressure plate 23 and the two lower separation plates are both in an inward pressure state. The upper active separation pressure plate 23 is first pulled outward, and a stack of lunch boxes are placed into the through-hole structure of the bottom plate 2 installed in the limiting column, and then the upper active separation pressure plate 23 is released. At this time, the bottom lunch box is clamped by the lower active separation plate 17 and the lower passive separation plate 28 of the two lower separation plates, and the second bottom and several upper lunch boxes are pressed by the passive separation pressure plates 24 and the upper active separation pressure plates 23 on the two upper separation pressure plates, so that the bottom lunch box is in a separated state from the other lunch boxes.

[0035] When receiving the command to automatically separate the lunch box, the electromagnet 16 first contracts its iron core, pulling the lower active separation sheet 17, and at the same time, 17 pulls the lower passive separation sheet 28 through the pull rope 4, and the two separation sheets are separated from the bottom lunch box at the same time, and the bottom lunch box falls down under the action of gravity. The lower active separation sheet electromagnet 16 is powered on for 0.5 seconds and then powered off, and the iron core of the lower active separation sheet electromagnet 16 extends to drive the lower active separation sheet 17 to move inward, and the lower passive separation sheet 28 also moves inward at the same time under the action of the tension spring 26, and the two lower separation sheets 17 and 28 return to their initial positions. 0.5 seconds after the lower active separation plate electromagnet 16 is powered off, the upper separation plate electromagnet 11 is powered on and the iron core extends out to push the upper active separation plate block 10, and then the upper active separation plate connecting rod 12 and the upper active separation plate push-pull rod 14 act to pull the upper active separation plate 23 outward, and then the remaining lunch boxes fall and are blocked by the two lower separation plates, the lower active separation plate 17 and the lower passive separation plate 28. 0.5 seconds after the upper separation plate electromagnet 11 is powered on, the upper active separation plate 23 presses the second and upper lunch boxes at the bottom under the action of the compression spring 7 and returns to the initial state. Under normal circumstances, the lunch box separation detection switch 22 is triggered once and then restored within 2 seconds after the electromagnet is powered on, indicating that the lunch box has been separated. If the lunch box separation detection switch 22 is not triggered within 1 second after the upper separation plate electromagnet 11 loses power, the lunch box separation action is repeated. If it is not triggered twice in a row, a warning of abnormal separation of the lunch box is issued to remind the staff to repair. When the lunch box is below the detection range of the residual detection switch 19, the system issues a prompt to add the lunch box in time. After the two lower active separation sheet electromagnets 16 and the upper separation pressing plate electromagnet 11 are powered on and off respectively, the separation of a lunch box is completed.

[0036] In summary, the lunch box separation device of the present invention can automatically separate the packaged boxes of a specific size, effectively ensuring that only one packaged box is separated each time, and multiple packages are not separated at one time. The simple, accurate and fast characteristics of the electromagnet make the separation action fast and accurate. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.

[0037] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
