[0060] As Figure 1 , 2As shown, in order to improve production efficiency, a two-piece cartridge production process is usually adopted, which is as follows: first, a composite rod is made by a compound machine, and then low-temperature non-combustible tobacco particles are filled into the cavities at both ends of the composite rod by a filling machine, and after sealing, the rod is wrapped with tipping paper, and then the rod is cut into two pieces to obtain finished cigarette rods. Therefore, the cartridge filling machine in the embodiment adopts a two-filling-unit (including a first filling unit and a second filling unit) combined mode, each of the above-mentioned filling units comprises a suction and rotation module A, a filling module, a gluing module C and a sealing module D, wherein a reversing module B is arranged at the receiving position of the first filling unit, a reversing module B is arranged at the output position of the second filling unit, the output position of the first filling unit and the receiving position of the second filling unit are correspondingly arranged, and a reversing module B is arranged therebetween, which is used to take out the rod in the vertical storage groove of the first filling unit and place it into the second filling unit after being turned by 180°, so as to realize the combination of the two filling units.

[0061] The filling module adopts an existing commercially available device, which can accurately put a certain amount of tobacco particles into the inner cavity of the rod.

[0062] The suction and rotation module A comprises a horizontal rotating disc A1, the central shaft of which is driven by a servo motor, and a plurality of vertical storage grooves A2 are uniformly arranged on the peripheral sidewall, each of which rotates in the circumferential direction and sequentially passes through the receiving position, the filling position, the gluing position, the sealing position and the output position. When working, each vertical storage groove A2 stops rotating when it rotates to the above-mentioned positions, and then continues to rotate after completing the corresponding process. A negative pressure adsorption hole connected with a negative pressure mechanism is arranged in each vertical storage groove A2 to adsorb the rod Y and ensure the firmness of the rod.

[0063] The reversing module B comprises a reversing frame, and further comprises:

[0064] The transmission unit has a continuous input end for connecting a driving mechanism, and an output end that moves intermittently in the circumferential direction;

[0065] The accommodation unit is arranged at the output end and has a plurality of rod storage positions, which are arranged in groups, and the rod storage positions of adjacent groups are arranged in sequence in the rotation direction of the output end;

[0066] The suction unit has an access end for connecting a negative pressure mechanism, and a suction end connected with the rod storage position;

[0067] The number of groups of rod storage positions is equal to the number of times the output end stops rotating in one circumferential rotation.

[0068] Specifically, as Figures 3a-3cAs shown, the reversing frame B1 of the present application is provided with a Malta mechanism, the driving wheel B21 of the Malta mechanism (i.e. the driving mechanism) is provided with an input shaft B22 (i.e. the continuous input end), the driven wheel B23 of the Malta mechanism is provided with an output shaft B24 (i.e. the circumferential intermittent output end), and the input shaft B22 and the output shaft B24 are respectively connected with the reversing frame B1 through rotating bearings, both of which are horizontally arranged and extend out of the reversing frame B1. In this embodiment, the driven wheel B23 is a grooved wheel with four radial grooves with an included angle of 90°, which will appear four times of rotation-stop cycle when the driving wheel B21 rotates one circle.
