In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] Please refer to Figures 1 to 5 The utility model discloses an automatic removal device for small cigarette packs, comprising a main support frame 51, a conveyor belt 2, a cigarette pushing mechanism, a horizontal moving mechanism, a clamping mechanism, a horizontal cutting mechanism, a vertical cutting mechanism, a cigarette separating mechanism and an empty shell extracting mechanism.

[0036] The conveyor belt 2 is arranged beside the main support frame 51, and is used to convey the small box cigarette packs 3. The small box cigarette packs 3 are placed on the conveyor belt of the conveyor belt 2 and conveyed toward the end of the conveyor belt 2. Side panels are arranged on both sides of the conveyor belt 2 to form a cigarette pack conveying channel to ensure that the cigarette packs are conveyed along the cigarette pack conveying channel. A baffle 1 is arranged at the end position of the conveyor belt 2, so that when the small box cigarette packs 3 are conveyed to the end position of the conveyor belt 2, under the limiting effect of the baffle 1, they can no longer be conveyed by the conveyor belt 2 but are temporarily located at the end position of the conveyor belt 2, and the end position of the conveyor belt 2 corresponds to the cigarette pushing mechanism. The cigarette pack conveying channel formed by the conveyor belt 2 should meet the actual size requirements to ensure that the cigarette packs can be stably and accurately conveyed to the cigarette pushing mechanism.

[0037] The cigarette pushing mechanism is installed on the conveyor belt 2, and the cigarette pushing mechanism and the clamping mechanism are located on both sides of the conveyor belt 2. The cigarette pushing mechanism includes a cigarette pushing cylinder 5 and a cigarette pushing cylinder push rod 6 arranged on the cigarette pushing cylinder 5.

The lateral part of the movable clamp plate 11 is located above the clamp support platform 7 and can form a space for clamping the small box cigarette package with the clamp support platform 7. At this time, when the small box cigarette package is fed between the movable clamp plate 11 and the clamp support platform 7, the movable clamp plate 11 rotates toward the clamp support platform 7 to realize that the bottom surface of the lateral part of the movable clamp plate 11 and the top surface of the clamp support platform 7 are in contact with the upper and lower wide surfaces of the small box cigarette package, thereby realizing the clamping of the small box cigarette package. When clamping, the end of the small box cigarette package partially extends out of the clamping mechanism to facilitate the horizontal cutting mechanism and the vertical cutting mechanism to cut the end of the small box cigarette package. The vertical part of the L-shaped movable clamping plate 11 is inclinedly provided with a slide groove 14 on both sides, and the front end of the clamping cylinder push rod 13 of the clamping cylinder 15 is provided with a connecting rod 52, and the two ends of the connecting rod 52 are located in the slide groove 14. The clamping cylinder 15 drives the clamping cylinder push rod 13 to extend and retract, so as to drive the connecting rod 52 to act on the movable clamping plate 11, so as to realize the clamping of the small box cigarette package by rotating in the direction close to the clamp support platform 7 or to realize the release of the clamping by rotating in the direction away from the clamp support platform 7. The clamp support platform 7 is detachably provided with an end positioning block 9 and a side positioning block 8 on one side facing the movable clamping plate 11. There are two side positioning blocks 8, and together with the end positioning block 9, a space for placing and limiting the small box cigarette package is formed. At this time, when the small box cigarette package 3 is located in the space for placing and limiting the small box cigarette package formed by the side positioning block 8 and the end positioning block 9, the small box cigarette package 3 cannot be translated on the top surface of the clamp support platform 7. A gasket 10 is installed inside the movable clamping plate 11 (towards the side of the clamp support platform 7) for protecting and clamping the cigarette package. The gasket 10 is made of a flexible material.

[0039] In a preferred embodiment, the clamp of the clamping device (movable clamping plate 11 and clamp support platform 7) is detachable, and each positioning block (end positioning block 9 and side positioning block 8) is adjustable to accommodate small boxes of cigarette packages of different specifications.

[0040] The horizontal moving mechanism is arranged on the main support frame 51 and can realize horizontal drive. The horizontal moving mechanism includes a screw motor 16, a screw 18, a screw nut 19, a slide rail 20 and a slider 21. The screw motor 16 is fixedly mounted on the main support frame 51. The screw 18 is rotatably mounted on the main support frame 51 through a screw support seat 22 and is connected to the screw motor 16 through a coupling 17 so as to be driven to rotate by the screw motor 16. The screw nut 19 is mounted on the screw 18. The slider 21 is fixedly connected to the screw nut 19. The slide rail 20 is fixedly mounted on the main support frame 51 and is consistent with the extension direction of the screw 18. The slider 21 is slidably mounted on the slide rail 20. The clamping mechanism is mounted on the screw nut 19 and the slider 21, and specifically, the clamp support table 7 of the clamping mechanism is fixedly mounted on the screw nut 19 and the slider 21 to improve the movement stability of the clamp. During implementation, the screw motor 16 drives the screw 18 to rotate, thereby driving the screw nut 19 and the slider 21 to move along the extension direction of the slide rail 20, and the clamp support platform 7 moves therewith, so as to move from the cigarette pushing mechanism to the horizontal cutting mechanism, the vertical cutting mechanism, the cigarette separation mechanism and the empty shell extraction mechanism, or move back to the cigarette pushing mechanism.

[0041] The horizontal cutting mechanism is arranged beside the moving path of the clamping mechanism, and is used to complete the cutting of the upper and lower wide surfaces of the small box cigarette pack. The horizontal cutting mechanism includes a horizontal cutting motor support frame 23, a first horizontal cutting motor 24 and a second horizontal cutting motor 25, the first horizontal cutting motor 24 and the second horizontal cutting motor 25 are fixedly mounted on the horizontal cutting motor support frame 23, the first horizontal cutting motor 24 and the second horizontal cutting motor 25 are arranged vertically upward and downward, the output shaft of the first horizontal cutting motor 24 is provided with a first horizontal cutting high-speed roller 26, the output shaft of the second horizontal cutting motor 25 is provided with a second horizontal cutting high-speed roller 27, the first horizontal cutting high-speed roller 26 and the second horizontal cutting high-speed roller 27 are arranged vertically upward and downward, and there is a space between the two for the small box cigarette pack to pass through, so as to cut the upper and lower wide surfaces of the small box cigarette pack when the small box cigarette pack passes through. When the small box cigarette package moves with the clamping mechanism through the horizontal moving mechanism between the first horizontal cutting high-speed roller 26 and the second horizontal cutting high-speed roller 27, the first horizontal cutting high-speed roller 26 contacts the upper wide surface of the small box cigarette package, and the second horizontal cutting high-speed roller 27 contacts the lower wide surface of the small box cigarette package. Under the action of the first horizontal cutting motor 24 driving the first horizontal cutting high-speed roller 26 to rotate and cut, and the second horizontal cutting motor 25 driving the second horizontal cutting high-speed roller 27 to rotate and cut, the upper and lower wide surfaces of the small box cigarette package can be cut.

[0042] The vertical cutting mechanism is arranged beside the moving path of the clamping mechanism, and is used to complete the cutting of the left and right narrow sides of the small box cigarette pack. The vertical cutting mechanism includes a first lifting cylinder support frame 29, a first lifting cylinder 28, a vertical cutting motor support plate 33, a first vertical cutting motor 34 and a second vertical cutting motor 35. The first lifting cylinder 28 is fixedly mounted on the first lifting cylinder support frame 29, and the vertical cutting motor support plate 33 is mounted on the first lifting cylinder push rod 30 of the first lifting cylinder 28 to achieve lifting. The output shaft of the first vertical cutting motor 34 is provided with a first vertical cutting high-speed roller 36, and the output shaft of the second vertical cutting motor 35 is provided with a second vertical cutting high-speed roller 37. The first vertical cutting high-speed roller 36 and the second vertical cutting high-speed roller 37 are arranged horizontally on the left and right sides, and there is a space between the two for the small box cigarette pack to pass through so as to cut the left and right narrow sides of the small box cigarette pack when the small box cigarette pack passes through.

[0043] When the small box of cigarette packs (referred to as the cigarette packs to be vertically cut 38 at this time) moves between the first vertical cutting high-speed roller 36 and the second vertical cutting high-speed roller 37 with the clamping mechanism through the horizontal moving mechanism, the cigarette packs to be vertically cut 38 are located above or below the space through which the first vertical cutting high-speed roller 36 and the second vertical cutting high-speed roller 37 allow the small box of cigarette packs to pass. At this time, the small box of cigarette packs stops with the clamping mechanism, and the first lifting cylinder 28 drives the vertical cutting motor support plate 33 to move upward or downward to drive the first vertical cutting motor 34 and the second vertical cutting motor 35 to move upward or downward. At this time, the first vertical cutting high-speed roller 36 and the second vertical cutting high-speed roller 37 move vertically and pass through the small box of cigarette packs.

[0044] The first vertical cutting high-speed roller 36 contacts the left narrow side of the small box cigarette package, and the second vertical cutting high-speed roller 37 contacts the right wide side of the small box cigarette package. Under the action of the first vertical cutting motor 34 driving the first vertical cutting high-speed roller 36 to rotate and cut, and the second vertical cutting motor 35 driving the second vertical cutting high-speed roller 37 to rotate and cut, the left and right narrow sides of the small box cigarette package can be cut.

[0045] A plurality of vertical cutting motor support plate guide rods 31 are fixed below the vertical cutting motor support plate 33. The first lifting cylinder support frame 29 is also equipped with linear bearings 32 whose number is the same as the vertical cutting motor support plate guide rods 31.

[0046] In a preferred embodiment, the position spacing of each high-speed roller cutter of the horizontal cutting mechanism and the vertical cutting mechanism is adjustable to adapt to the cutting and removal of cigarettes of different brands and specifications.

[0047] In a preferred embodiment, the cutting accuracy of each high-speed roller of the horizontal cutting mechanism and the vertical cutting mechanism should meet the actual production requirements, and the tool material should be suitable for cutting cellophane and paper boxes. The vertical movement of the vertical cutting mechanism should be stable and accurate to ensure smooth cutting without damaging the cigarettes.

[0048] The cigarette separation mechanism is arranged beside the moving path of the clamping mechanism, and is used to suck and remove the cut transparent paper and box skin, and to suck and separate the cigarette from the cigarette pack. The cigarette separation mechanism includes a first rotary cylinder support frame 39, a first rotary cylinder 40, a first suction cylinder 41 and a suction plate 43. The first rotary cylinder 40 is fixedly mounted on the first rotary cylinder support frame 39, the first suction cylinder 41 is mounted on the first rotary cylinder 40 and driven to rotate by the first rotary cylinder 40, and the suction plate 43 is mounted on the first suction cylinder push rod 42 of the first suction cylinder 41.

The suction plate 43 is equipped with a vacuum generator or connected to an external exhaust air source so that the transparent paper, box skin and cigarette can be sucked and separated during implementation. In a preferred embodiment, a plurality of small holes are opened at the end surface of the suction plate 43, and the small hole negative wind (negative pressure or exhaust adsorption) can realize the suction adsorption of transparent paper, box skin and cigarette. The small holes of the suction plate 43 correspond to the positions of the cigarettes to ensure that the cigarettes can be adsorbed. The suction plate of the cigarette separation mechanism is replaceable to adapt to the removal of cigarettes of different brands and specifications.

[0049] When the small cigarette pack cut by the horizontal cutting mechanism and the vertical cutting mechanism moves to the cigarette separation mechanism with the clamping mechanism and stops temporarily, the first suction cylinder 41 drives the suction plate 43 to abut against the cut transparent paper and box skin of the small cigarette pack, and then the suction plate 43 adsorbs, the first suction cylinder 41 drives the suction plate 43 to move away in the opposite direction, and the first rotating cylinder 40 drives the first suction cylinder 41 to rotate, driving the first suction cylinder 41 to rotate to the specified position, and the suction plate 43 closes the suction, placing the transparent paper and box skin on the In the next process, the first rotating cylinder 40 then rotates in the opposite direction to drive the first suction cylinder 41 to reset, and the first suction cylinder 41 extends again to drive the suction plate 43 to abut against the cigarette 44, and then through the suction plate 43 adsorption, the first suction cylinder 41 drives the suction plate 43 to move away in the opposite direction and the first rotating cylinder 40 drives the first suction cylinder 41 to rotate, driving the first suction cylinder 41 to rotate to the specified position, the suction plate 43 closes the suction, and the cigarette 44 is placed in the next process, thereby completing the cigarette box and cigarette separation work of the small box cigarette pack.

The suction cup 48 is equipped with a vacuum generator or connected to an external exhaust air source so that the transparent paper, the box skin and the cigarette can be adsorbed during implementation. In a preferred embodiment, the suction nozzle 49 of the suction cup 48 can realize suction adsorption of the empty shell of the small box through negative wind (negative pressure or exhaust adsorption).

[0051] When the small cigarette pack (the small empty shell 50 at this time) from which the transparent paper, the box skin and the cigarettes are extracted moves with the clamping mechanism to the empty shell extraction mechanism and stops temporarily, the clamping cylinder 15 of the clamping device is started again, driving the connecting rod 52 of the clamping cylinder push rod 13 to move in the slide groove 14, thereby driving the movable clamping plate 11 to rotate around the rotating shaft 12, and the movable clamping plate 11 is opened. When the movable clamping plate 11 is opened to a certain angle, the clamping of the small empty shell 50 is released and a certain position is made above the small empty shell 50, and the second rotating cylinder 46 is started, driving the second lifting cylinder 47 to rotate to the small empty shell At the top, the second lifting cylinder 47 starts and drives its push rod to drive the suction cup 48 to descend to abut against the empty shell of the small box. After the suction nozzle 49 on the suction cup 48 abuts against the empty shell of the small box, the suction is started to suck the empty shell of the small box 50; then the second lifting cylinder 47 starts again to drive its push rod to rise, so that the empty shell of the small box 50 leaves the clamping mechanism with the suction cup 48. At this time, the second rotating cylinder 46 starts again and completes the rotation action, driving the second lifting cylinder 47 and the suction cup 48 to rotate to the specified position, the suction cup 48 turns off the suction, and the empty shell of the small box 50 is placed in the next process, thereby completing the extraction of the empty shell of the small box 50.

[0052] In a preferred embodiment, the clamping device needs to work closely with the major mechanisms (horizontal cutting mechanism, vertical cutting mechanism, cigarette separation mechanism and empty shell extraction mechanism, etc.) to maximize the cigarette removal speed of the device without interference. It should be noted that the cigarette separation mechanism can be designed according to actual needs and is not limited to a single setting. Double-sided or multiple suction mechanisms can be set to improve separation efficiency.

[0054] The small cigarette pack automatic removal device operates normally, and the small cigarette pack 3 that needs to be removed is placed at the front end of the conveyor belt 2. The small cigarette pack 3 is stably transported to the end through the conveyor belt 2 and faces the cigarette pushing mechanism.
