[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model relates to a double-spiral feeding mechanism for a packaging machine;

[0019] Example: The feeding mechanism includes a steel frame 1, a first geared motor 2, a second geared motor 3, a coarse helical rod 12, and a fine helical rod 13. The two supports of the steel frame 1 are bolted to the first geared motor 2 and the second geared motor 3, respectively. A first gear transmission box 6 is provided at the output shaft of the first geared motor 2. A first rotating connecting rod 8 is driven to the output shaft of the first gear transmission box 6. A first coupling 10 is provided at one end of the first rotating connecting rod 8. One end of the first coupling 10 is connected to the coarse helical rod 12. A second gear transmission box 7 is provided at the output shaft of the second geared motor 3. A second rotating connecting rod 9 is driven to the output shaft of the second gear transmission box 7. A second coupling 11 is provided at one end of the second rotating connecting rod 9. One end of the second coupling 11 is connected to the fine helical rod 13.

[0020] It also includes a support frame 17 and a hopper 18. The top of the support frame 17 is equipped with a first conveying channel 14 and a second conveying channel 15. The coarse spiral rod 12 and the fine spiral rod 13 are respectively assembled inside the first conveying channel 14 and the second conveying channel 15. The hopper 18 is mounted on the top of the first conveying channel 14 and the second conveying channel 15 and corresponds to the first conveying channel 14 and the second conveying channel 15. The top of the hopper 18 is provided with an opening and closing valve plate 19.

[0021] Furthermore, in order to ensure good stability and reduce the impact of vibration on the first gear transmission box 6 and the second gear transmission box 7, a shock-absorbing bracket 4 is provided at the bottom of the first gear transmission box 6, and a shock-absorbing bracket 5 is provided at the bottom of the second gear transmission box 7. Both the shock-absorbing bracket 5 and the shock-absorbing bracket 4 are bolted to the steel frame 1.

[0022] Furthermore, in order to better deliver the conveyed materials to the packaging machine and reduce the impact of dust, a feeding channel 16 is provided on the side of the support frame 17, and a bag dust collector 20 is installed at the top of the feeding channel 16.

[0023] Furthermore, in order to better control the hopper 18 corresponding to the first conveying channel 14 and the second conveying channel 15, the opening and closing valve plate 19 divides the inner cavity of the hopper 18 into a coarse material cavity and a fine material cavity, which correspond to the first conveying channel 14 and the second conveying channel 15.

[0024] Furthermore, in order to improve the rotational accuracy of the first coupling 10 and the second coupling 11 and reduce radial runout, the first coupling 10 and the second coupling 11 are respectively located at the bearing seat of the first conveying channel 14 and the bearing seat of the second conveying channel 15.

[0025] Furthermore, for better transmission, belt drives are used between the first gear transmission box 6 and the first rotating connecting rod 8, as well as between the second gear transmission box 7 and the second rotating connecting rod 9.

[0026] In use, the feeding mechanism of this solution is aligned with the packaging machine, so that the feeding channel 16 corresponds to the material discharge port of the packaging machine, realizing the feeding and packaging operation. The coarse or fine material chamber of the hopper 18 is opened by the opening and closing valve plate 19, so that the coarse or fine material falls into the corresponding first conveying channel 14 and second conveying channel 15. The rotation of the coarse spiral rod 12 and the fine spiral rod 13 realizes the material conveying, which makes it easy to push the coarser or finer material to the feeding channel 16 and feed it into the packaging machine. This solution has good adaptability and improves the convenience of use.
