The first push rod 413 can be inserted into the second groove 35 under the drive of the first linear module 411, so that the base rod material can be pushed out of the second groove 35.

[0031] A slitting roller 43 is provided on one side of the driving wheel 31 close to the positioning mechanism 42. Figure 5 As shown, the slitting roller 43 is fixed between the driving wheel 31 and the positioning mechanism 42 through a fixing frame 44, and the slitting roller 43 is rotatably connected to the fixing frame 44. A third motor 45 is provided on the side of the fixing frame 44 away from the slitting roller 43. The third motor 45 is rotatably connected to the slitting roller 43 through a coupling. A plurality of accommodating holes 46 are provided on the circumference of the slitting roller 43. The accommodating holes 46 are parallel to the axis of the slitting roller 43. The accommodating holes 46 correspond to the second groove 35. The base rod material in the second groove 35 can be pushed into the accommodating holes 46 through the first push rod 413.

[0032] The positioning mechanism 42 includes a second support frame 420, to which a second linear module 421 is fixedly connected. A positioning rod 423 is fixedly connected to the slider of the second linear module 421 through a second connecting block 422. The positioning rod 423 extends toward the side of the slitting roller 43, and the positioning rod 423 can be driven by the second linear module 421 to be inserted into the accommodating hole 46. The first push rod 413 is coaxially arranged with the positioning rod 423. By adjusting the length of the positioning rod 423 in the accommodating hole 46, the length of the base rod material pushed into the accommodating hole 46 is adjusted, and then the base rod material is cut to a fixed length using the slitting assembly 5.

[0033] The slitting assembly 5 is arranged above the slitting roller 43. The slitting assembly 5 includes a third support frame, and a third linear module 51 is arranged on the third support frame. The third linear module 51 is arranged vertically. A fourth motor 52 is fixedly connected to the slider of the third linear module 51.

The cutting blade 53 is arranged close to the slitting roller 43, and the cutting blade 53 is driven by the third linear module 51 to move toward the slitting roller 43, thereby slitting the base rod material.

[0034] The sorting component 6 is located below the fixed-length component 4. The sorting component 6 includes a pushing mechanism and a conveying mechanism 61. The pushing mechanism and the conveying mechanism 61 are respectively located on both sides of the slitting roller 43. The pushing mechanism includes a fourth support frame. The fourth support frame is provided with a fourth linear module. The slider of the fourth linear module is fixedly connected to the second push rod through the third connecting block. The second push rod extends toward one side of the slitting roller 43 and corresponds to the accommodating hole 46. When the base rod material is cut by the slitting component 5, the positioning rod 423 exits the accommodating hole 46, and the slitting roller 43 rotates so that the accommodating hole 46 faces the second push rod. Under the action of the fourth linear module, the second push rod is inserted into the accommodating hole 46, and the base rod material in the accommodating hole 46 is pushed out from the other side and falls onto the conveying mechanism 61.

The driving pulley 613 and the driven pulley 614 are connected by a belt 615. The belt 615 is arranged parallel to the conveying plate 610, and a push plate 616 is provided on the belt 615. When the belt 615 rotates, the push plate 616 can pass over the conveying plate 610, thereby pushing the base rod material placed in the arc-shaped groove to move toward the end of the conveying plate 610.

[0036] During use, the second push rod pushes the cut different base rod materials onto the conveying plate 610 and arranges them in sequence according to the set order. The push plate 616 drives the base rod materials to move to the end of the conveying plate 610. The end of the conveying plate 610 is connected to the rolling device, and the heated cigarette is rolled into shape through the rolling device.

[0037] The rolling device is a common heated cigarette rolling device on the market, which does not fall within the scope of protection of the present invention and will not be described in detail again.

[0038] The present invention can realize fixed-length cutting of different base rod materials and sort the different base rod materials, thereby reducing the workload in the process of developing heated cigarettes and improving the efficiency and quality of heated cigarette development.

[0039] Example 2 This embodiment provides a method for cutting and assembling heated cigarette base rod materials, using a cutting and assembling device for heated cigarette base rod materials as described in Example 1, including the following steps: Open the silo door and put different base rod materials into different silos. The base rod materials fall into the first groove at the discharge port at the bottom of the silo. The first motor drives the discharge roller to rotate, and the base rod materials fall from the first groove into the second groove. The second motor drives the conveyor belt to rotate, so that the second groove is transported to the end of the conveyor belt. The first push rod on the pushing mechanism extends into the second groove, pushing the base rod material in the second groove into the receiving groove on the slitting roller. The positioning rod on the positioning mechanism extends into the receiving groove on the slitting roller. The positioning mechanism is used to control the length of the base rod material in the receiving groove, and the base rod material is cut by the slitting assembly.
