The driving motor drives the rotating transmission mechanism 3 and the box mold on the rotating transmission mechanism 3 to rotate, so that the cigarette box 9 is moved from one station to the next station. The negative pressure adsorption module 5 comprises a feeding cylinder 51, a pull-out suction disc 52 and a negative pressure seat 53, the negative pressure seat 53 is fixedly installed at both ends of the base plate 1, the middle part is provided with the feeding cylinder 51, the push rod of the feeding cylinder 51 is fixedly connected with the pull-out suction disc 52, the pull-out suction disc 52 is connected with a vacuum system, the vacuum system is composed of a vacuum tank and a vacuum pump, and the inner cavity of the pull-out suction disc 52 is used for vacuumizing, so that the pull-out suction disc 52 can be tightly adsorbed between the surface of the cigarette box paper 61.

[0039] Further, the feeding cylinder 51 is provided with two groups of upper and lower groups, the pull-out suction disc is also provided with two groups of upper and lower groups, and is divided into the upper suction disc 11 and the lower suction disc 12; when working, the cigarette box paper 9 is located between the two pull-out suction discs 52, the feeding cylinder 51 drives the pull-out suction disc 52 to adsorb the upper and lower ends of the cigarette box paper 9, the feeding cylinder 51 is retracted, the pull-out suction disc 52 pulls apart the upper and lower ends of the cigarette box paper by a gap, the gap is inserted into the gap, and the blade 22 is inserted into the gap. The cutting module 23 drives the blade 22 to cut the cigarette box paper. Similarly, the blade 22 is also divided into two pieces of upper and lower blades.

[0040] For convenience of description, the upper feeding cylinder and the corresponding upper suction disc 11 can be regarded as the upper end adsorption mechanism 13, and the lower feeding cylinder and the corresponding lower suction disc 12 can be regarded as the lower end adsorption mechanism 14.

[0041] As shown in the figure, Figure 3 The cigarette box 6 comprises a cigarette box paper 61, a tin package 62 and a sticker 63, the inside of the tin package 62 is used for placing cigarettes, the outside is covered with the cigarette box paper 61, and the end of the cigarette box paper 61 close to the opening is attached with the sticker 63. The space surrounded by the cigarette box paper 61 and the sticker 63 wraps the tin package 62.

[0042] In use, the cigarette box 6 is placed on the box mold on the rotating transmission mechanism 3, the rotating transmission mechanism 3 rotates, and the cigarette box 6 is placed below the feeding cylinder 51, at this time, the cigarette box 6 is located in front of the cutting module. The feeding cylinder 51 moves to press the pull-out suction disc 52 on the cigarette box 6 and adsorb the cigarette box paper 61 through negative pressure, and then the feeding cylinder 51 is reset, and in the resetting process, the pull-out suction disc 52 drives the cigarette box paper 61 to move, so that the gap between the cigarette box paper 61 and the tin package 62 is increased.

[0043] After the feeding cylinder 51 is reset, the pushing cylinder 4 drives the sliding block of the sliding guide rail 7 to move forward, and simultaneously drives the cutting module 2 to move forward. The cutting module 2 is inserted into the gap between the cigarette case paper 61 and the tin foil 62 under the action of the pushing cylinder 4, and the cigarette is cut by cutting.

[0044] As shown in Figure 4 , the cigarette case 6 is pushed into the first station 31 of the rotary transmission mechanism 3 through the input mechanism 8, and the cigarette case 6 is transported to the second station 32 through the rotary transmission mechanism 3. At the first cutting device of the second station 32, the cigarette case 6 is first adsorbed by the upper end adsorption mechanism 13 and the lower end adsorption mechanism 14, and the upper end adsorption mechanism 13 and the lower end adsorption mechanism 14 are connected to the cylinder to adsorb the cigarette case 6, so that a large gap is generated between the cigarette case paper 61 and the tin foil 62. Figure 5

[0045] As shown in Figure 6 , since the internal cigarette is finally to be extracted, the tin foil 62 cannot have adhesion, but the cut paper 63 still adheres the upper and lower ends of the tin foil 62 (including the upper end of the tin foil 62 and the lower end of the tin foil 62) to the tobacco tin paper, and the internal cigarette is still not easy to extract, so the second cutting device is used again for cutting at the third station. After cutting, the cigarette case 6 reaches the third station 33 with the rotary transmission mechanism 3, and the horizontal cutting tool 9 of the second cutting device cuts the tin foil 62 (the tin foil 62 is not fixed in any way except that the upper end of the tin foil is adhered by the paper). During operation, the horizontal cutting tool 9 is horizontally attached to the front end of the cigarette case 6 by using the horizontal cutting mechanism, a gap is squeezed out between the upper end of the tin foil 62 and the lower end of the tin foil 62 by slight pressing, the horizontal cutting tool 9 is driven by the module of the second cutting device to move left and right, and the residual paper 63 adhered to the tin foil 62 is cut again through the gap, so that the tin foil 62 is not affected by any external force. At this time, the tin foil 62 is stored in the cigarette case paper 61 and is not fixed to the cigarette case 9.

[0046] As shown in Figure 7 , after the third station 33 is completed, the cigarette case 6 reaches the fourth station 34 with the rotary transmission mechanism 3, and the upper end of the tin foil 62 is adsorbed by the pulling suction disc 10. The pulling suction disc 10 is driven to move by the extension and retraction of the cylinder, the tin foil in the cigarette case is pulled out by the pulling suction disc 10, and the tin foil 62 is separated from the cigarette case paper 61.

[0047] ​The present application increases the gap between the cigarette paper and the tin foil by the combination of the feeding cylinder and the pulling-out suction disc, and inserts the blade into the gap to cut and decompose the cigarette paper without damaging the cigarette.

[0048] The non-damage cigarette cutting device and method of the soft package cigarette box is simple in non-damage cigarette cutting, simple in device, time-saving and labor-saving in automatic operation. Only the gap between the cigarette paper and the tin foil is cut, the reliability is high and the cigarette is not damaged, the waste of various cigarette raw and auxiliary materials such as tobacco, filter, water-proof paper and cigarette paper is effectively reduced, therefore, the practicality is high and the applicable value is great.
