[0002] During the production process of cigarette sorting and distribution, the produced cigarettes need to be packed into boxes, strips and cartons at once, so as to facilitate subsequent transportation or storage. During the sorting and distribution process, the cartons of cigarettes need to be unpacked by automated machinery, so that the cigarette strips can be pushed out of the cigarette packaging box and enter the next system replenishment link. Currently, the unpacking of cigarette packaging boxes is done by automated machinery to automatically cut the tapes at both ends. Figure 1 As shown, after the tape is cut, the two long flaps 7 and the two short flaps 8 lose the fixing force of the tape. At this time, when the pushing mechanism is extended into the box to push the cigarette stack to the outside, the two short flaps 8 will be folded into the inside of the tobacco packaging box along with the push rod; at this time, in the subsequent recycling process of the empty packaging box, the supporting role of the two short flaps 8 inside the packaging box requires the staff to manually take out the two short flaps 8 and then put the packaging box on the ground and flatten it. This work not only increases the workload of the staff, but also causes a serious backlog in the recycling of packaging boxes during the peak sales season; at the same time, due to the supporting role of the short flaps inside the packaging box, the packaging box is always in a rectangular state, and it is easy to accumulate at the corners of the conveyor belt, which in turn causes damage to the equipment around the conveyor belt.

The back of the vertical plate 41 is provided with two symmetrically arranged first guide seats 411, and the back of the rectangular pushing frame 43 is provided with two first guide rods 431 that are guided and matched with the first guide seats 411. The horizontal push electric push rod 42 is horizontally arranged on the back of the vertical plate 41, and the back of the rectangular pushing frame 43 is fixedly connected to the output end of the horizontal push electric push rod 42. The conveyor belt 1 is located below the top of the support frame 2, and the receiving platform 3 and the pushing assembly 4 are respectively located on both sides of the conveyor belt 1.

[0026] The utility model can position the packaging box on the conveyor belt 1 through the positioning component 5, and can respectively open the two long rocking covers 7 at one end of the packaging box through the two toggle components 6, and then drive the rectangular pushing frame 43 to move by pushing the electric push rod 42 horizontally, and the rectangular pushing frame 43 can enter the packaging box. After that, the stack of cigarette strips can be completely and automatically pushed out, and the stack of cigarette strips can be pushed onto the receiving platform 3 synchronously, thereby improving the efficiency of taking out the stack of cigarette strips from the packaging box.

[0027] The positioning assembly 5 includes a positioning electric push rod 51, a top plate 52 and a second guide rod 521. A bidirectional electric push rod 53 is installed on the top of the top plate 52. A clamping plate 54 is provided on the two output ends of the bidirectional electric push rod 53. The top of the support frame 2 is provided with a second guide seat 21 that guides and cooperates with the second guide rod 521. The positioning electric push rod 51 is vertically arranged on the top of the support frame 2. The positioning electric push rod 51 and the second guide rod 521 are symmetrically arranged. The output ends of the positioning electric push rod 51 and the second guide rod 521 are fixedly connected to the top of the top plate 52.

[0028] The positioning electric push rod 51 can drive the top plate 52 to move downward, and the top plate 52 can abut against the top of the packaging box. The bidirectional electric push rod 53 drives the two clamping plates 54 to clamp the two sides of the packaging box.

[0029] The clamping plate 54 is provided with a plurality of weight-reducing grooves 541 arranged at equal intervals, which can not only clamp the packaging box, but also reduce the weight of the clamping plate 54 itself and reduce the driving burden of the bidirectional electric push rod 53.

[0030] The toggle assembly 6 includes a suspension 61, a first electric push rod 62, a second electric push rod 63 and a U-shaped frame 64. The head end of the U-shaped frame 64 is provided with a mounting plate 65, and the mounting plate 65 is provided with a folded angle plate 66 which is symmetrically arranged in the upper and lower directions. The suspension 61 is horizontally arranged on the support frame 2, the first electric push rod 62 is horizontally arranged on the suspension 61, the second electric push rod 63 is vertically arranged on the output end of the first electric push rod 62, and the U-shaped frame 64 is horizontally arranged on the output end of the second electric push rod 63.

[0031] The first electric push rod 62 can drive the second electric push rod 63, the U-shaped frame 64 and the angle plate 66 to move horizontally, and the second electric push rod 63 can drive the U-shaped frame 64 and the angle plate 66 to move up and down.

[0032] Two symmetrically arranged feed notches 432 are provided on the rear half of the rectangular pushing frame 43. The two short rocking covers 8 can automatically enter the feed notches 432 by their own resilience. When the electric push rod 42 is pushed horizontally to drive the rectangular pushing frame 43 to reset, the two feed notches 432 can respectively abut against the two short rocking covers 8 and rotate in opposite directions, so that the short rocking covers 8 can be flipped outwards, which facilitates the subsequent self-gravity flattening and recycling of the empty packaging boxes.

[0033] An abutting overhanging plate 433 for abutting the short swing cover 8 is provided on one inner wall of the feed notch 432 , and the abutting overhanging plate 433 is used to guide the short swing cover 8 into the feed notch 432 .

[0034] The cross section of the abutting extended plate 433 is arc-shaped, and the short swing cover 8 enters the feed notch 432 more smoothly.

[0035] The head end of the rectangular pusher frame 43 is provided with a plurality of vertical mounting frames 434 arranged at equal intervals. A roller shaft 435 is rotatably provided on the vertical mounting frame 434. The roller shaft 435 contacts the back of the tobacco rod stack without causing friction damage to the tobacco rods.

[0036] Working principle: The conveyor belt 1 transports the package box with the tape cut to the support frame 2, and then the positioning electric push rod 51 can drive the top plate 52 to move down until the top plate 52 abuts against the top of the package box. The two-way electric push rod 53 drives the two clamps 54 to clamp the two sides of the package box. Then the two toggle components 6 work in sequence. The second electric push rod 63 of the toggle component 6 located on the top works first to drive the folding plate 66 to move down, so that the height of the folding plate 66 is lower than the long swing cover 7 located above. Then the first The electric push rod 62 drives the second electric push rod 63 and the angle plate 66 to move toward the packaging box. The angle plate 66 hits the outer wall of the long rocking cover 7 located below. Then the long rocking cover 7 is recessed into the packaging box. The end of the angle plate 66 away from the mounting plate 65 is just on the inside of the upper long rocking cover 7. Then the second electric push rod 63 drives the angle plate 66 to move upward. The upper long rocking cover 7 is driven by the angle plate 66 to turn outward. Then another toggle assembly 6 turns the lower long rocking cover 7 outward as well. Then the electric push rod 42 is pushed horizontally. Drive the rectangular pushing frame 43 to move, and the head end of the rectangular pushing frame 43 presses the two short swing covers 8 to turn into the packaging box, and then the cigarette stacks in the packaging box are pushed out of the packaging box by the rectangular pushing frame 43, and all the cigarette stacks can be moved to the receiving platform 3, and the electric push rod 42 is pushed horizontally to drive the rectangular pushing frame 43 to move in the opposite direction, and the two short swing covers 8 turned into the interior of the packaging box can respectively abut on the two abutting overhanging plates 433, and the short swing covers 8 can then enter the feeding notch 432, and then the feeding notch 432 is opened. The movable short swing cover 8 gradually flips outward, and then the positioning component 5 stops working, and the conveyor belt 1 transports the packaging box away for lower-level recycling processing. Because the abutting extended plate 433 has flipped the two short swing covers 8 outward from the tobacco carton, when the empty packaging box is transported to the top of the recycling conveyor belt through the conveyor belt 1, the packaging box will fall onto the recycling conveyor belt. Due to the effect of gravity, the quadrilateral of the packaging box is unstable. When the packaging box falls on the recycling conveyor belt, it will become a diamond state or a flat state, which is convenient for later recycling.
