Description

Technical Field

[0001] This utility model belongs to the technical field of tobacco processing equipment, specifically relating to a pre-cutting device for cigarette paper in a cigarette rolling machine. Background Technology

[0002] During the cigarette manufacturing process, cigarette paper needs to be cut into small segments of fixed length to facilitate subsequent processing.

[0003] For example, CN204914012U discloses a shearing paper cutting wheel assembly, including a frame, a paper cutting drum and a paper cutting blade rotatably connected to the frame, and the tails of the paper cutting drum and the paper cutting blade meshing through gear transmission. The paper cutting drum includes a wheel body and inserts, with the inserts circumferentially distributed on the wheel body and gaps between adjacent inserts. The paper cutting blade has blades distributed on it, each blade corresponding to one of the inserts. The side of each insert has a shearing section that cooperates with the blade. The paper cutting drum and the paper cutting blade rotate against each other under gear transmission, and the inner side of the blade begins to overlap with the shearing section, forming a V-shaped angle. During rotation, the shearing section and the blade cut from the inside out. Because both the blade and the shearing groove are rotating during operation, the possibility of collision between the blade and the groove is relatively high. Furthermore, the cut cigarette paper will bend due to the shape of the paper cutting wheel, which does not meet the pre-processing requirements of cigarette paper in some cigarette manufacturing processes. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide a pre-cutting device for cigarette paper in a cigarette rolling machine, which can cut cigarette paper into several cigarette paper units of the same length at a set frequency. The cut cigarette paper is flat and is conveyed to the subsequent processing unit. It can also press patterns onto the cigarette paper and is suitable for cigarette paper of various thicknesses.

[0005] The technical problem solved by this utility model can be achieved by the following technical solution: A cigarette paper pre-cutting device for a cigarette machine, comprising cigarette paper, a support mechanism, an input mechanism, and a cutting mechanism. The cigarette paper is integrally formed. The support mechanism includes several support members for supporting the cigarette paper. The input mechanism includes a connecting part and several roller parts. The connecting part is disposed on both sides of the input mechanism. The roller parts are disposed between the connecting parts. The roller parts include an upper roller and a lower roller. The two ends of the upper roller are connected to an upper gear part, and the two ends of the lower roller are connected to a lower gear part. The upper gear part and the lower gear part are meshed. The cigarette paper is located between the upper roller and the lower roller. Through the transmission of the upper gear part and the lower gear part, the cigarette paper can be moved to the cutting mechanism to be cut into cigarette paper units.

[0006] The connecting part is provided with several connecting grooves and connecting parts. The connecting parts and connecting grooves match each other. The end of the upper roller passes through the connecting part and the upper gear part, and the lower roller passes through the lower end of the connecting part and the lower gear part. The lower gear part is externally connected to a drive device, which makes the lower gear part rotate and drives the lower roller and the upper gear part to rotate, thereby driving the upper roller to rotate together.

[0007] The connector can move up and down in the connecting groove, changing the distance between the upper and lower rollers.

[0008] The upper and lower rollers are provided with grooves to form patterns as the cigarette paper moves.

[0009] The cutting mechanism includes a guillotine section and several telescopic rods. The upper end of the guillotine section is connected to the telescopic rods, and the telescopic rods are externally connected to a driving device, which causes the telescopic rods to move up and down at a fixed frequency, thereby driving the guillotine section to move up and down to cut the cigarette paper.

[0010] The cutting edge of the guillotine is set at an angle downwards.

[0011] It also includes a limiting guide section, with one side of the cigarette paper unit located inside the limiting guide section and pushed by the subsequently cut cigarette paper, moving along the extension direction of the limiting guide section.

[0012] Compared with the prior art, this utility model has the following advantages: This utility model can cut cigarette paper into several cigarette paper units of the same length at a set frequency. The cut cigarette paper is flat and is conveyed to the subsequent processing unit. It can also press patterns on the cigarette paper and is applicable to cigarette paper of various thicknesses.

[0019] Combined with appendix Figures 1 to 3 As shown, this embodiment discloses a pre-cutting device for cigarette paper in a cigarette machine, including cigarette paper 1, a support mechanism 2, an input mechanism 3, and a cutting mechanism 4. The cigarette paper 1 is integrally formed. The support mechanism 2 includes several support members 21. The rear half of the cigarette paper 1 is located above the support members 21. The support members 21 are used to support the cigarette paper 1, facilitating the entry of the cigarette paper 1 into the input mechanism 3 and improving the smoothness of the movement of the cigarette paper 1. The input mechanism 3 includes a connecting part 31 and several roller parts 32. The connecting part 31 is disposed on both sides of the input mechanism 3, and the roller parts... 32 is disposed between the connecting parts 31. The roller part 32 includes an upper roller 321 and a lower roller 322. The upper roller 321 is connected to the upper gear part 33 at both ends, and the lower roller 322 is connected to the lower gear part 34 at both ends. The upper gear part 33 and the lower gear part 34 are meshed together. The cigarette paper 1 is located between the upper roller 321 and the lower roller 322 and is held by the upper roller 321 and the lower roller 322. Through the transmission of the upper gear part 33 and the lower gear part 34, the cigarette paper 1 can be moved to the cutting mechanism 4 to be cut to form the cigarette paper unit 11.

[0020] In conjunction with the above installation structure, the connecting part 31 is provided with a plurality of connecting grooves 311 and connecting members 312. The connecting members 312 and the connecting grooves 311 are matched with each other. A single connecting groove 311 is provided with a single connecting member 312. Preferably, the connecting member 312 is a T-shaped structure. The end of the upper roller 321 passes through the connecting member 312 and the upper gear part 33. The lower roller 322 passes through the lower end of the connecting part 31 and the lower gear part 34. The lower gear part 34 is externally connected to a driving device 36. The driving device 36 adopts a common driving structure such as a motor. The driving device 36 can make the lower gear part 34 rotate and drive the lower roller 322 and the upper gear part 33 to rotate. Since the lower gear part 34 and the upper gear part 33 are meshed and connected to each other, the upper roller 321 is driven to rotate in coordination. When the upper roller 321 and the lower roller 322 rotate, they drive the cigarette paper 1 to move and flatten the cigarette paper 1 at the same time.

[0021] In conjunction with the above, preferably, the drive device 36 can adjust the rotation speed of the lower gear 34, thereby changing the moving speed of the cigarette paper 1 and thus changing the length of the cigarette paper unit 11.

[0022] Combined with the above installation structure, the connector 312 can be externally connected to the drive device 36. The drive device 36 adopts a common drive structure such as a motor, so that the connector 312 can move up and down in the connecting groove 311. While the upper gear part 33 and the lower gear part 34 are kept in meshing connection, the distance between the upper roller 321 and the lower roller 322 can be changed to suit cigarette paper 1 of different thicknesses.

[0023] In conjunction with the above installation structure, the upper roller 321 and the lower roller 322 are provided with grooves 35 to form patterns when the cigarette paper 1 moves and is flattened, thereby increasing the aesthetics of the cigarette paper 1.

[0024] In conjunction with the above, the cutting mechanism 4 includes a guillotine section 41 and several telescopic rods 42. Preferably, two telescopic rods 42 are used, with a single telescopic rod 42 connected to the left and right sides of the upper end of the guillotine section 41. The telescopic rods 42 are externally connected to a drive device 36. The drive device 36 adopts a common drive structure such as a motor. The drive device 36 causes the telescopic rods 42 to move up and down at a fixed frequency, driving the guillotine section 41 to move up and down to cut the cigarette paper 1. Preferably, the drive device 36 can adjust the frequency of the telescopic rods 42 to move up and down, thereby changing the frequency of the guillotine section 41 to move up and down, and thus changing the length of the cigarette paper unit 11.

[0025] In combination with the above, preferably, the blade of the guillotine 41 is inclined downward to facilitate the rapid cutting of the cigarette paper 1. When the blade of the guillotine 41 is not in contact with the cigarette paper 1, the cigarette paper 1 moves at a fixed speed due to the transmission of the input mechanism 3. When the blade of the guillotine 41 contacts the cigarette paper 1, the cigarette paper 1 is cut to form a cigarette paper unit 11. The cigarette paper unit 11 is pushed by the cigarette paper 1 on the rear side, thereby continuing to move.

[0026] In conjunction with the above, it also includes a limiting guide 5. One side of the cigarette paper unit 11 is located inside the limiting guide 5 and is pushed by the subsequently cut cigarette paper 1 to move along the extension direction of the limiting guide 5, so as to prevent the cigarette paper unit 11 from accumulating or misaligning during movement.

[0027] This invention can cut cigarette paper into several cigarette paper units of the same length at a set frequency. The cut cigarette paper is flat and is conveyed to the subsequent processing unit. It can also press patterns on the cigarette paper and is applicable to cigarette paper of various thicknesses.

[0028] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
