The operating principle of the lower cover unfolding mechanism 2 is as follows:

when a cigarette reaches the station of the lower seal cover unfolding mechanism 2, the lifting motor 105 drives the spiral lifter 104 to rotate, so that the descending centering mechanism 108 on the lifting frame 103 descends until the trigger rod 1087 on the descending centering mechanism 108 is contacted with the top of the cigarette box, at the moment, the photoelectric detection switch 1086 is triggered, a trigger signal is sent to the PLC control system, and the PLC control system starts to orderly control each mechanism to execute actions. At this time, the transmission line 1 and the lifting motor 105 stop working, so that the smoke box stays under the lower cover unfolding mechanism 2, then the long holding cylinder 1063 acts to make the left cover unfolding device 109 close to the right cover unfolding device 109 until the smoke pressing plates 1100 on the two cover unfolding devices 109 press the two upper covers of the smoke box from the two sides, then the suction cup telescopic cylinder 1094 extends out, and the cover suction cup 1102 sucks the lower cover of the smoke box and pulls out a gap of 5-10 mm. At this time, the cutter 1101 is positioned at the highest position and at the center of the lid deployment device 109, and after the lid suction cup 1102 pulls out the lower lid, the cutter lift cylinder 1098 is immediately extended, so that the cutter 1101 is inserted into the gap between the lower lid and the smoke box. At this time, the cutter deployment cylinder 1093 also extends, so that the two cutters 1101 cut off the adhesive tape between the lower cover and the smoke box when the two cutters are separated to both sides, thereby completing the deployment of the lower cover.

In addition, because the descending centering mechanism 108 is connected with the door frame 101 through the linkage chain 1085, under the action of the chain wheel a1089 and the chain wheel B1090, the lifting frame 103 and the descending centering mechanism 108 form a stroke distance-multiplying relationship, that is: the crane 103 descends by exactly 2 times the descending distance of the descending centering mechanism 108. Since the lid deployment device 109 is fixed below the crane 103, the cigarette pressing plate 1100 of the lid deployment device 109 just reaches the position of the lid on the cigarette box when the trigger lever 1087 at the lower end of the lower centering mechanism 108 contacts the top of the cigarette box.

Referring to fig. 12, the structure and operation principle of the upper cover unfolding mechanism 3 are the same as those of the lower cover unfolding mechanism 2, but the upper cover and the lower cover of the cigarette box are symmetrically arranged, so that the cover sucking disc 1102 on the upper cover unfolding mechanism 3 is arranged above the cigarette pressing plate 1100 and the cutter 1101.

When the cigarette box reaches the 4 stations of the clamping side ear opening mechanism, the pushing plate 404 can find the front end of the cigarette box, the long cylinder 407 on the left side acts, the cigarette box is pushed backwards through the pushing plate 404, the cigarette box reaches the middle position of the clamping side ear opening mechanism 4 through the positioning of the photoelectric switch, then the lifting sliding table cylinder 411 controls the side ear suckers 403 on two sides to descend, and the rotating cylinder 405 acts to enable the side ear suckers 403 to turn to the side ear positions of the cigarette box and suck the side ears of the cigarette box. At the moment, the rotary cylinder 405 moves reversely to pull open the side lug of the smoke box, and finally the side lug pressing cylinder 412 acts to enable the side lug pressing rod 402 to press the side lug, and then the sucker is loosened to lift and reset.

When the cigarette box with the opened upper sealing cover, the opened lower sealing cover and the opened side ears is conveyed to the station where the clasping and centering mechanism 7 is located, the cigarette clamping plate lifting cylinder 707 drives the cigarette clamping plates 704 on the two sides to descend, then the cigarette clamping cylinder 705 acts to enable the cigarette clamping plates 704 on the two sides to simultaneously contract inwards, so that the cigarette box is located at the center line position of the cigarette pushing mechanism 6, and the cigarette pile in the cigarette box can be conveniently pushed out by the cigarette pushing mechanism 6.

Referring to fig. 18 to 19, the cigarette pushing mechanism 6 includes a cigarette pushing frame 601 and a cigarette pushing cylinder 603 fixed on the top of the cigarette pushing frame 601, the top of the cigarette pushing frame 601 is further symmetrically and slidably connected with two cigarette pushing rods 602, the end portions of the two cigarette pushing rods 602 are fixedly connected with a cigarette pushing plate assembly 605, and the telescopic rod of the cigarette pushing cylinder 603 is in transmission connection with the cigarette pushing plate assembly 605.

The cigarette pushing mechanism 6 mainly operates by driving the cigarette pushing plate assembly 605 to move back and forth through the cigarette pushing cylinder 603, so that the cigarette pushing plate assembly 605 enters the cigarette box and pushes the cigarette stack in the cigarette box into the buffer belt conveyor 8.

Referring to fig. 20 to 23, the cigarette pushing plate assembly 605 includes a cigarette pushing mounting plate 613 fixedly connected to two cigarette pushing rods 602 and the telescopic rods of the cigarette pushing cylinder 603, width expanding cylinders 612 are symmetrically and fixedly connected to both sides of the cigarette pushing mounting plate 613, a width expanding plate 609 is fixedly connected to the telescopic rods of the width expanding cylinders 612, a seventh linear guide 611 is symmetrically and fixedly connected to the inner side of the cigarette pushing mounting plate 613, a height adjusting plate 615 is slidably connected to the seventh linear guide 611, a height expanding plate 610 is fixedly connected to the top of the height adjusting plate 615, a sprocket chain mechanism 616 is installed in the middle of the cigarette pushing mounting plate 613, a connecting piece 614 is fixedly connected to the chain of the sprocket chain mechanism 616, the connecting piece 614 is fixedly connected to the height adjusting plate, a height adjusting transmission shaft 607 is rotatably connected to the cigarette pushing frame 601, a height adjusting motor 605 is fixedly installed at one end of the height adjusting transmission shaft 607 on the cigarette pushing frame 601, and the output shaft of the height adjusting motor 605 is connected to the end of the sprocket chain mechanism 616, and the other end of the height adjusting transmission shaft 607 is connected to the sprocket chain mechanism 616.
