[0031] A driven gear ring 15 that cooperates with the rotary cleaning component is installed on the weighing cylinder 14. The inner wall of the weighing cylinder 14 is slidably connected to a discharge valve seat 16. Two T-shaped suspension rods 17 are installed on the discharge valve seat 16. Both T-shaped suspension rods 17 are slidably connected to the weighing cylinder 14. Both T-shaped suspension rods 17 are sleeved with springs 18 that are limited by the weighing cylinder 14.

[0032] The two cyclone cleaning components each include a cyclone cleaning pipe 19 rotatably connected to the lifting frame 2, a drive sleeve 20 rotatably connected to the bracket 5, and a differential shaft 21. The differential shaft 21 is connected to the drive sleeve 20 via a belt. A differential gear 22 is mounted on the differential shaft 21. The differential gear 22 is respectively engaged with the inner ring gear 10 and the driven ring gear 15.

[0033] When the weighing cylinder 14 rotates to the top of the two conveying parts 6, the weighing cylinder 14 is driven by the inner gear ring 10, and the weighing cylinder 14 is driven by the inner gear ring 10 to perform the fabric discharge operation;

[0034] When the two weighing cylinders 14 are rotated to the two discharge ports of the double-headed discharge pipe 4, the two weighing cylinders 14 are staggered with the two differential shafts 21, and the two weighing cylinders 14 remain stationary when the fabric enters;

When the fabric enters, the two weighing cylinders 14 remain stationary. When the fabric is fed in, the weight of the fabric in the weighing cylinder 14 is monitored in real time through the setting of the weighing sensor 13. After the two weighing cylinders 14 quantitatively feed the fabric, the two weighing cylinders 14 are respectively rotated to the top of the two conveying components 6 under the driving action of the indexing frame 9. When working, the two conveying components 6 work synchronously. After the two conveying components 6 work, the flour quantitative holding container is fed in, and the weighing cylinder 14 moves.

After the rotary cleaning seat 23 and the weighing cylinder 14 rotate, they are coordinated with the discharge push rod 25 to completely clean the fabric in the weighing cylinder 14 out of the weighing cylinder 14, thereby reducing the residual rate of flour in the weighing cylinder 14 and the influence of the residual flour on the weighing results in the subsequent weighing process.
