During the reciprocating rotation of the ring frame 32, the box fixing frame 4 and the box placement frame 5 can be in the correct position at the workstation.

[0033] The box fixing frame 4 includes a square frame 41, on which a box support plate 42 is provided to open the box opening. Two telescopic plates 43 are rotatably provided on the front and rear sides of the square frame 41. A telescopic cylinder 44 is provided between the two telescopic plates 43. The two ends of the telescopic cylinder 44 are respectively hinged to the two telescopic plates 43. The flipping seat 6 is provided with fixing holes that cooperate with the telescopic plates 43.

[0034] The support plate 42 is tilted inward towards the square frame 41, which facilitates its easy insertion into the packaging box and prevents the box lid from being pressed into the box body, thus preventing subsequent sealing. The support plate 42 is easy to fold and will be opened by the egg tray when it is inserted, without affecting the insertion of the egg tray. The telescopic plate 43 is installed on the outside of the square frame 41. The square frame 41 has a through hole for the telescopic plate 43 to extend and retract. When the telescopic rod of the telescopic cylinder 44 retracts, it drives the telescopic plate 43 connected to both ends of the telescopic cylinder 44 to rotate. During the rotation, one end of the telescopic plate 43 extends out of the through hole and inserts into the fixing hole on the flipping seat 6, thus completing the connection between the box fixing frame 4 and the flipping seat 6.

[0035] The box placement frame 5 is provided with a plurality of spaced rotating rollers 51 on one side near the box fixing frame 4. A first motor 52 is provided on the box placement frame 5, and the first motor 52 is connected to the rotating rollers 51. A lifting cylinder 53 is fixedly provided on the box placement frame 5. A lifting plate 54 is fixedly provided at the end of the telescopic rod of the lifting cylinder 53. The lifting plate 54 can pass through the space between two adjacent rotating rollers 51.

[0036] During the rotation of the rotating roller 51, the packaging box is transported to the designated position. The lifting plate 54 lifts the packaging box when its height decreases, so that the box fixing frame 4 can smoothly fix the opening of the packaging box when it descends. In this embodiment, the box fixing frame 4 is connected to the support frame 32 by a cylinder.

[0037] The lifting device 7 includes a lifting cylinder 71 fixedly connected to the frame 1. The end of the telescopic rod of the lifting cylinder 71 is fixedly connected to the lifting seat 72.

The end of the locking connecting rod 75 away from the locking cylinder 74 is fixedly connected to the locking plate 76. A fixing rod 63 that cooperates with the locking plate 76 is provided on the tilting seat 6.

[0038] When the snap-fit ​​plate 76 is connected to the fixed rod 63, the tilting seat 6 is fixedly connected to the lifting seat 72. At this time, the second motor 73 is connected to the second conveyor belt 62. Both the tilting seat 6 and the lifting seat 72 are equipped with gears, and the two gears can mesh. The gear on the lifting seat 72 is connected to the second motor 73, and the gear on the tilting seat 6 is connected to the second conveyor belt 62. When the snap-fit ​​plate 76 is connected to the fixed rod 63, the two gears mesh. When the snap-fit ​​plate 76 is separated from the fixed rod 63, the second conveyor belt 62 is de-powered.

[0039] The egg tray conveying device 2 includes a fixed conveying frame 21 and a movable conveying frame 22. A first limiting plate 23 is rotatably provided at the rear end of the fixed conveying frame 21. A movable slide rail 11 is provided on the frame 1. The movable conveying frame 22 is slidably installed on the movable slide rail 11. The movable conveying frame 22 can move back and forth between the fixed conveying frame 21 and the flipping seat 6. A second limiting plate 24 is fixedly provided on both sides of the middle part of the movable conveying frame 22. A partition plate insertion device 8 is fixedly connected to the frame 1 above the movable conveying frame 22. A third limiting plate 12 is rotatably provided on the frame 1.

[0040] The partition insertion device 8 includes a positioning plate 81 fixedly connected to the frame 1. An insertion cylinder 82 is mounted on the top front side of the positioning plate 81. A push plate 83 is mounted at the end of the telescopic rod of the insertion cylinder 82. A placement frame 84 is mounted on the lower front side of the positioning plate 81. A push slide rail 85 is mounted on the placement frame 84, and a push plate 86 is slidably mounted on the push slide rail 85. A driven roller 87 and a driving roller 88 are mounted opposite each other at the bottom of the placement frame 84 and the bottom of the positioning plate 81. An insertion motor 89 is mounted on the positioning plate 81, and the insertion motor 89 is driven by the driving roller 88.

[0041] The pusher plate 83 inserts the partition between the drive roller 88 and the driven roller 87. The drive roller 88 rotates and pushes the partition downward between the two stacks of egg trays. The second limiting plate 24 limits the partition so that the partition can be smoothly inserted between the two stacks of egg trays.

[0042] One side of the frame 1 is provided with a box conveyor 9 that can transport the packaging boxes to the box placement rack 5.

[0043] During the operation, egg cartons filled with eggs are stacked in sequence and placed on the fixed conveyor 21. At this time, the front end of the mobile conveyor 22 is connected to the fixed conveyor 21, and the third limiting plate 12 rotates to the rear of the mobile conveyor 22. The stacked egg cartons are transported to the mobile conveyor 22. After two stacks of egg cartons are transported to the mobile conveyor 22, the first limiting plate 23 rotates to the rear end of the fixed conveyor 21 to prevent the stacked egg cartons from moving toward the mobile conveyor 22.

[0044] Two stacks of egg trays are restricted by the third limiting plate 12 below the partition insertion device 8. The push plate 83 on the insertion cylinder 82 pushes down to insert the partition between the driven roller 87 and the driving roller 88. The insertion motor 89 works, the driving roller 88 rotates, pushing the partition downward. With the assistance of the second limiting plate 24, it is inserted between the two stacks of egg trays. Then the third limiting plate 12 is lifted, and the moving conveyor 22 moves backward along the moving slide rail 11 until it stops in front of the lifting device 7.

[0045] The packaging box is transported along the box conveyor 9 to the box placement rack 5. When the box fixing frame 4 can be connected to the packaging box without using the lifting plate 54, the lifting plate 54 does not need to rise. When the height of the packaging box decreases, the lifting plate 54 can lift the packaging box so that the box fixing frame 4 can be smoothly fixed at the opening of the packaging box when it descends. The rising height of the lifting plate 54 is adjustable, the egg tray stacking height is adjustable, and the production line can adapt to various packaging box specifications, making it more versatile.

[0046] After the box fixing frame 4 is fixedly connected to the packaging box, the ring frame 3 rotates, and the box fixing frame 4 rotates to the top of the flipping seat 6. The flipping seat 6 carrying the egg tray rises under the action of the lifting device 7, and the egg tray is put into the packaging box. The flipping seat 6 separates from the lifting device 7 and connects to the box fixing frame 4. At this time, the box fixing device on the other side of the ring frame 3 is fixing the packaging box.

[0047] The lifting device 7 is reset, and the box fixing device on the other side rotates to above the lifting device 7. The lifting device 7 rises, and the flipping seat 6 connected to the box fixing frame 4 separates from the box fixing frame 4 and connects to the lifting device 7. The lifting device 7 carries the flipping seat 6 down, and the moving conveyor 22 transports the two stacks of egg cartons to the flipping seat 6, and then repeats the boxing work.

[0048] The rotating motor 13 can rotate forward and reverse. The two sets of box fixing devices work alternately. The empty packaging box rotates to the top of the lifting device 7, and the packaging box filled with egg trays rotates to the other side. At this time, the packaging box opens upward after rotation, and the box fixing frame 4 rises and separates from the packaging box. If the lifting plate 54 has risen, it will fall down. The packaging box filled with egg trays falls on the rotating roller 51, and then enters the next box sealing operation. The box fixing frame 4 re-fixes the new packaging box.

[0049] For those skilled in the art, any changes, modifications, substitutions, and variations made to the embodiments without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
