[0037] Embodiment 1

[0038] like Figures 1 to 6 As shown, this embodiment provides a cigarette pack inner lining paper folding device, which is configured to fold the short side of the inner lining paper of the cigarette pack 100, and the cigarette pack inner lining paper folding device includes a packaging wheel 1, a folding mechanism 2, a pusher 3 and a receiving member 4. Among them, the packaging wheel 1 includes two synchronously rotating turntables 11, and a receiving groove 111 is provided on the edge of the turntable 11. The long side of the cigarette pack 100 overlaps with the two receiving grooves 111 at the same time, so that the cigarette pack 100 can be placed horizontally between the two receiving grooves 111, and the short sides of the inner lining paper of the cigarette pack 100 are exposed in the receiving groove 111. The folding mechanism 2 is opposite to the edges of the two turntables 11, and the folding mechanism 2 includes a frame 21 and two folding components 22. The frame 21 includes two opposite connecting plates 211, and each connecting plate 211 is provided with a folding component 22, so as to realize the synchronous folding of the short sides of the inner lining paper of the cigarette pack 100, and ensure the efficiency of the folding of the short sides of the inner lining paper of the cigarette pack 100.

[0039] The folding assembly 22 includes a first side panel 221, a folding member 222 and a second side panel 223. The first side panel 221 is connected to the connecting plate 211 and faces the packaging wheel 1. The receiving member 4 includes a receiving plate 40. The receiving plate 40 is attached to the bottom of the folding mechanism 2 and extends to the first side panel 221. The first side panel 221 has an arc-shaped notch 2211. The surface of the arc-shaped notch 2211 includes a plane portion 22111 and an arc surface portion 22112. The arc surface portion 22112 faces away from the connecting plate 211. The folding member includes a vertical plate 2221. The vertical plate 2221 is arranged parallel to the side of the first side panel 221 away from the connecting plate 211, wherein a gap is left between the vertical plate 2221 and the first side panel 221, and a gap is left between the bottom surface of the vertical plate 2221 and the receiving plate 40. The second side plate 223 is connected to the vertical plate 2221 and faces the packaging wheel 1. When the packaging wheel 1 drives the cigarette pack 100 to rotate to the folding mechanism 2, the second baffle is in contact with the upper short side 101 of the inner lining paper of the cigarette pack 100. Specifically, the second baffle is in contact with the outer wall of the upper short side 101, and the upper short side 101 is folded as the turntable 11 rotates. When the turntable 11 drives the cigarette pack 100 to be completely placed between the two second side plates 223, the lower short side 102 of the inner lining paper is flush with the plane part 22111, the packaging wheel 1 pauses for a predetermined time, and the pusher 3 pushes the cigarette pack 100 into the receiving plate 40. Then the packaging wheel 1 continues to rotate, and the pusher 3 continues to push the cigarette pack 100 along the receiving plate 40 toward the frame 21, so that the lower short side 102 of the inner lining paper is folded. Specifically, when the pusher 3 pushes the cigarette pack 100 from the position of the second side plate 223 to the frame 21, the lower short side 102 of the lining paper will first overlap with the flat surface 22111 of the arc-shaped notch 2211, and then push to the arc surface 22112 and finally approach the frame 21. The vertical plate 2221 is placed on the inner side of the first side plate 221. When the cigarette pack 100 is moved, the receiving plate 40 receives the cigarette pack 100. The first side plate 221 The cigarette pack 100 is limited, and the vertical plate 2221 forms a crease on the lower short side 102. As the cigarette pack 100 moves to the curved surface 22112, the curved surface 22112 faces away from the connecting plate 211, and the curved surface 22112 and the crease together bend the lower short side 102 upward. As the pusher 3 pushes the cigarette pack 100, the cigarette pack 100 is completely pushed through the curved surface 22112, and the folding of the lower short side 102 is completed. The cigarette pack 100 with the folded short side of the inner liner paper is moved to the next process by the transport mechanism.

[0040] At the same time, the first side plate 221 limits the cigarette package 100, and the receiving plate 40 receives the cigarette package 100, which can ensure the stability of the cigarette package 100 during movement, avoid the cigarette package 100 from being deflected during movement, and ensure the folding quality of the upper short side 101 and the lower short side 102 of the lining paper.

[0041] The cigarette pack 100 inner lining paper folding device provided in the present embodiment, in the process that the turntable 11 drives the cigarette pack 100 to rotate, when the cigarette pack 100 rotates to the folding mechanism 2, the upper short side 101 of the inner lining paper will fit with the second side plate 223, and the upper short side 101 will be folded as the turntable 11 rotates. At this time, the cigarette pack 100 is completely placed between the two second side plates 223, and the pushing member 3 pushes the cigarette pack 100 into the receiving plate 40 and moves toward the frame 21, and the lower short side 102 of the inner lining paper of the cigarette pack 100 is first overlapped with the flat portion 22111, and as the cigarette pack 100 moves, the vertical plate 2221 forms a crease on the lower short side 102, and the arc surface portion 22112 is directed away from the connecting plate 211, and the lower short side 102 is bent upward under the combined action of the arc surface portion 22112 and the crease, and the folding of the lower short side 102 is finally completed. Since the lower short edge 102 of the inner lining paper is bent on the basis of forming a crease, it can avoid rebounding of the lower short edge 102 of the inner lining paper during the folding process, thereby avoiding the problem of obvious skewness of the lower short edge 102 of the inner lining paper after folding, thereby ensuring the aesthetics of the cigarette package 100 that has completed the inner lining paper folding process.

[0042] When the cigarette pack 100 is completely rotated to between the two second side plates 223, the pusher 3 pushes the cigarette pack 100 into the receiving plate 40, and the cigarette pack 100 is separated from the receiving groove 111. At the same time, the pusher 3 will not affect the rotation of the turntable 11. At this time, the packaging wheel 1 only needs to pause for a predetermined time when the cigarette pack 100 is completely located between the two second side plates 223 to ensure that the cigarette pack 100 can enter the receiving plate 40, and there is no need to pause for a long time. When the next cigarette pack 100 on the packaging wheel 1 is opposite to the folding mechanism 2, the upper short side 101 of the lining paper can also be folded through the second side plate 223. When the next cigarette pack 100 is completely located between the two second side plates 223, the packaging wheel 1 pauses for a predetermined time again, and the pusher 3 pushes the next cigarette pack 100 into the receiving plate 40 and moves toward the frame 21, and the lower short side 102 of the lining paper of the next cigarette pack 100 is folded through the vertical plate 2221 and the first side plate 221. This process only requires the packaging wheel 1 to pause for a short time, and it is not necessary to wait until the upper short side 101 and the lower short side 102 of the liner paper are folded before continuing to rotate, which solves the problem of the packaging wheel 1 needing to pause for a long time when the short side of the liner paper of the cigarette pack 100 is folded in the prior art, so that the folding efficiency of the short side of the liner paper of the cigarette pack 100 is greatly improved, thereby achieving an increase in the processing speed of the cigarette pack 100. In this embodiment, the predetermined time is 0.06S-1S, so that the folding efficiency of the liner paper of the cigarette pack 100 is guaranteed.

[0043] In this embodiment, the folding member 222 further includes a connecting edge, wherein one end of the connecting edge is vertically connected to the side of the first side plate 221 away from the connecting plate 211, and the vertical plate 2221 is vertically connected to the other end of the connecting edge, so that the vertical plate 2221 can be placed parallel to the side of the first side plate 221 away from the connecting plate 211. At the same time, the two folding members 222 are connected by a connecting horizontal plate, and the connecting horizontal plate is fixed to the connecting plate 211, further ensuring the stability of the assembly of the two folding members 222.

[0044] In this embodiment, Figures 1 to 3 As shown in , the edge of the turntable 11 is provided with a plurality of receiving grooves 111, and the plurality of receiving grooves 111 are arranged at intervals. In this way, the packaging wheel 1 can drive a plurality of cigarette packs 100 to rotate at one time. After the folding of the short side of the inner lining paper of a cigarette pack 100 is completed, the next cigarette pack 100 will be driven to the folding mechanism 2, which reduces the interval time of the folding process of the short side of the inner lining paper of different cigarette packs 100, and further improves the processing efficiency of the folding of the short side of the inner lining paper of the cigarette pack 100. According to the wheel diameter of the turntable 11, the angle between different receiving grooves 111, the propulsion speed of the pusher 3 and the predetermined pause time of the packaging wheel 1, a reasonable rotation speed of the turntable 11 can be calculated. After the folding of the short side of the inner lining paper of the first cigarette pack 100 is completed and the pusher 3 is reset, the next cigarette pack 100 will rotate to the folding mechanism 2, and the continuity of the folding process of the short side of the inner lining paper of the cigarette pack 100 is realized. The calculation process of the rotation speed of the turntable 11 can be completed by a computer and does not belong to the key protection content of the present invention.

[0045] Exemplarily, the packaging wheel 1 further includes a first driving member, an intermediate bearing 12 and a connecting frame, wherein the output end of the first driving member is connected to the inner ring of the intermediate bearing 12, the two turntables 11 are respectively connected to the end faces on both sides of the inner ring, and the outer ring is fixedly connected to the connecting frame. The connecting frame can be fixedly connected to the work surface, and when the output end of the first driving member rotates, the inner ring of the bearing is driven to rotate, thereby causing the two turntables 11 to rotate synchronously. The outer ring is fixedly connected to the connecting frame to fix the bearing, further improve the smoothness of the rotation of the first driving member, and ensure the smoothness of the rotation of the turntable 11.

[0046] Preferably, the middle area of ​​the turntable 11 may be made into a hollow design to reduce the weight of the turntable 11 and increase the service life of the first driving member.

[0047] In this embodiment, the pushing member 3 includes a cigarette pushing member 31, wherein the cigarette pushing member 31 is placed between the two turntables 11 and can move back and forth toward the folding mechanism 2, and the receiving member 4 is placed on the side of the folding mechanism 2 away from the packaging wheel 1, and the receiving member 4 also includes a cigarette receiving member 41, which is opposite to the cigarette pushing member 31. The cigarette receiving member 41 can move back and forth toward the packaging wheel 1, and when the cigarette pushing member 31 is pushed out, the cigarette receiving member 41 retreats, and at the same time, the advancement speed of the cigarette pushing member 31 is consistent with the retreat speed of the cigarette receiving member 41. Specifically, the cigarette receiving member 41 is initially located between the two connecting plates 211 and close to the connection between the second side plate 223 and the vertical plate 2221. When the turntable 11 drives the cigarette pack 100 to rotate between the two second side plates 223, the cigarette pushing member 31 extends out, and the cigarette receiving member 41 and the cigarette pack 100 are fitted together toward the side of the folding mechanism 2. As the turntable 11 rotates, the fitting area between the cigarette receiving member 41 and the cigarette pack 100 increases. When the cigarette pack 100 is completely opposite to the cigarette receiving member 41, that is, when the cigarette pack 100 is completely placed between the two second side plates 223, the cigarette pushing member 31 and the cigarette pack 100 are fitted together toward the side of the packaging wheel 1. The packaging wheel 1 stops rotating for a predetermined time. At this time, the cigarette pushing member 31 The cigarette receiving member 41 gradually moves out, and the cigarette pack 100 gradually moves back, until the cigarette pack 100 is pushed into the receiving plate 40 and completely passes through the first side plate 221, and the upper short side 101 and the lower short side 102 of the inner lining paper are both folded. At this time, the transport mechanism moves the cigarette pack 100 with the inner lining paper short side folded to the next process, and the cigarette pushing member 31 moves back, and the cigarette receiving member 41 pushes out, and both return to the initial position, and wait until the next cigarette pack 100 rotates to the folding mechanism 2, and the cigarette pack 100 is completely placed between the two second side plates 223, and the packaging wheel 1 stops rotating for a predetermined time again, and the cigarette pushing member 31 and the cigarette receiving member 41 repeat the previous movement to complete the folding of the inner lining paper short side of the next cigarette pack 100. The pushing speed of the cigarette pushing member 31 and the retreating speed of the cigarette receiving member 41 are consistent, which can prevent the cigarette pack 100 from being deformed in the process of being moved by the two, affecting the quality of the cigarettes inside the cigarette pack 100 and the aesthetics of the cigarette pack 100.

[0048] Exemplarily, the pusher 3 also includes a second drive member, a gear and a rack, the output end of the second drive member is connected to the gear, the rack is meshed with the gear, and the cigarette pusher 31 is connected to the rack. When the second drive member is running, the gear will be driven to rotate, and the rack will perform linear motion, thereby moving the cigarette pusher 31. By controlling the steering of the output end of the second drive member, the steering of the gear can be controlled to achieve the reciprocating motion of the cigarette pusher 31. Further, the pusher 3 also includes a box body, which is fixed to the outer ring of the intermediate bearing 12, and the gear, rack and second drive member are all placed in the box body. At the same time, a guide groove is also provided inside the box body, and the rack part is placed in the guide groove, which further improves the stability of the rack operation and the stability of the movement of the cigarette pusher 31. At the same time, the pusher 3 and the packaging wheel 1 are reasonably arranged to miniaturize the cigarette pack lining paper folding device.

[0049] Furthermore, the cigarette pushing member 31 includes a first connecting rod and a cigarette pushing plate. One end of the first connecting rod is connected to the rack, and the other end is connected to the cigarette pushing plate, and the cigarette pushing plate is used to fit the cigarette pack 100. The setting of the cigarette pushing plate can ensure the contact area between the cigarette pushing member 31 and the cigarette pack 100, so that the pushing member 3 can push the cigarette pack 100 more smoothly.

[0050] In this embodiment, the receiving member 4 includes a third driving member, a crank member, a connecting rod and a guide rail member. The third driving member is drivingly connected to the crank member, one end of the connecting rod is rotationally connected to the crank member, and the other end is rotationally connected to the cigarette pushing member 31. The cigarette receiving member 41 is placed on the guide rail member, wherein the guide rail member is connected to the receiving plate 40. When the first driving member is running, the crank member is driven to rotate, and the connecting rod drives the cigarette receiving member 41 to perform a linear reciprocating motion on the guide rail, so that the cigarette receiving member 41 can reciprocate between the folding mechanisms 2. The receiving member 4 includes a support, and the guide rail member is placed on the support, so that the guide rail member and the receiving plate 40 can be located below the folding mechanism 2. Preferably, the third driving member is placed on the guide rail member to make the layout of the receiving member 4 more reasonable.

[0051] In this embodiment, the first driving member, the second driving member and the third driving member are all motors, wherein the motor can be selected from a stepper motor, a servo motor, a synchronous motor or an asynchronous motor, and the type of the motor is not specifically limited here.

[0052] Furthermore, the cigarette receiving member 41 includes a second connecting rod and a cigarette receiving plate, wherein one end of the second connecting rod is rotatably connected to the connecting rod, and the other end is connected to the cigarette receiving plate, which is used to fit with the cigarette package 100.

[0053] In this embodiment, the frame 21 also includes a crossbeam. Specifically, two connecting plates 211 are respectively placed at both ends of the crossbeam along the length direction. The setting of the crossbeam can ensure the stability of the overall structure of the frame 21 and further ensure the stability of the overall structure of the folding mechanism 2.
