Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1, 2, 3, and 4. In this embodiment of the present invention, a rotary feed valve includes a feed valve seat 1. The feed valve seat 1 has an inlet 2 and an outlet 3 on its upper and lower sides, respectively. A connecting cylinder 18 is rotatably mounted inside one end of the feed valve seat 1 via a first connecting shaft 4. A first blade 16 is mounted on the outer side of the connecting cylinder 18. A limiting end plate 8 is mounted inside the other end of the feed valve seat 1 via an outer bracket 11 and a support frame 12. The support frame 12 and the outer bracket 11 are slidably connected by a screw 13. A second blade 17 is rotatably mounted inside the limiting end plate 8 via a second connecting shaft 10. The blade 17 is inserted into the first blade 16, and the second connecting shaft 10 is inserted into the connecting cylinder 18. By adjusting the depth of the second blade 17 inserted into the first blade 16, the overall length of the feeding blade can be adjusted, thereby adjusting the amount of material fed in a single rotation, which improves the flexibility of the rotary feeding. One end of the first connecting shaft 4 is connected to the motor 6 via the belt flywheel assembly 5. The motor 6 is a servo motor, and the motor 6 is fixedly mounted on the outer wall of the feeding valve seat 1 via the motor base 7, so that the blade is driven to rotate at a uniform speed for feeding by the motor 6 and the belt flywheel assembly 5.

[0024] As shown in Figures 2 and 3, in order to adjust the depth of the second blade 17 inserted into the first blade 16, both the outer bracket 11 and the support frame 12 are U-shaped frames.

A locking bolt 15 is threaded on the upper side of the limiting sliding hole 14. One end of the screw 13 is vertically rotated and set in the middle of the outer bracket 11 through a bearing, and the middle of one end of the support frame 12 is threadedly connected to the screw 13. This allows the support frame 12 and the limiting end plate 8 to be adjusted laterally by rotating the screw 13, thereby adjusting the depth of the second blade 17 inserted into the first blade 16. Moreover, the adjustment is convenient, quick, and has high precision.

[0025] As shown in Figures 3 and 4, in order to improve the stability of the insertion of the first blade 16 and the second blade 17, insertion grooves 9 are provided inside the first blade 16 and the connecting cylinder 18. The second connecting shaft 10 and the second blade 17 are both inserted into the insertion grooves 9 laterally to limit the sliding of the first blade 16 and the second blade 17, thereby improving the stability of the insertion of the first blade 16 and the second blade 17.

[0026] As shown in Figures 2 and 3, in order to ensure the sealing of the connection of the limiting end plate 8, the limiting end plate 8 is also made into a circular plate, and a sealing gasket is provided on the outer wall of the limiting end plate 8, which facilitates the improvement of the sealing of the internal sliding connection between the limiting end plate 8 and the feed valve seat 1.

[0027] The working principle and usage process of this utility model are as follows: In use, the feeding valve seat 1 is installed on the feeding channel through the inlet 2 and the outlet 3.
