[0026] Preferably, the thread of the first spiral feed rotor 22 is a right-hand thread, and the rotation shaft 4 can drive the thread of the first spiral feed rotor 22 to rotate clockwise and drive the thread of the spiral blocking rotor 24 to rotate counterclockwise. In actual use, powder or liquid raw materials are respectively introduced into multiple feed ports 7, and the motor 3 drives the rotating shaft 4 and the stirring assembly 2 to rotate in the pulping tube 5, and the stirring rotor 21 is used to stir the raw materials in the pulping tube 5. The stirred raw materials continue to flow to the first spiral feed rotor 22, and the first spiral feed rotor 22 rotates and further stirs the materials. The stirred materials flow to the spacing rotor 23 under the drainage of the thread of the first spiral feed rotor 22, and flow out of the pulping tube 5 from the discharge port 6 below the spacing rotor 23, thereby completing the stirring of the raw materials. In addition, the rotating shaft 4 will also drive the thread of the spiral blocking rotor 24 to rotate counterclockwise, and the spiral blocking rotor 24 will resist or generate reflux to the raw materials flowing to the spacing rotor 23 during the rotation process to prevent the raw materials from continuing to flow backward. The utility model can realize multi-stage feeding, which is conducive to the step-by-step mixing of multiple raw materials, and is convenient for the uniform mixing of raw materials, and the pulping uniformity, continuity and consistency are good. The setting of the interval rotor 23 increases the raw material storage space above the discharge port 6, and the raw materials are stirred and drained by the first spiral feeding rotor 22, and the raw materials are blocked and refluxed by the spiral blocking rotor 24, which is conducive to the flow of raw materials and aggregation at the interval rotor 23, and facilitates the raw materials to flow out of the discharge port 6, improves the pulping efficiency, and has good pulping stability.

[0027] Furthermore, the pulping machine also includes a flange seat 11 arranged on the pulping cylinder 5, a front bearing chamber 12 arranged in the flange seat 11, and a front bearing body 13 arranged in the front bearing chamber 12, one end of the rotating shaft 4 is inserted into the front bearing chamber 12 and the flange seat 11 in sequence, the front bearing body 13 is sleeved on the outside of the rotating shaft 4, and the rotating shaft 4 is transmission-connected to the output end of the motor 3 in the flange seat 11.

In actual use, the front bearing body 13 is sleeved on the front end of the rotating shaft 4, and is supported on the rear end of the rotating shaft 4 by the rear bearing body 10, so that the two ends of the rotating shaft 4 are evenly stressed, which is convenient for the stable rotation of the rotating shaft 4 and is conducive to the uniform rotation of the stirring assembly 2 driven by the rotating shaft 4. The connection structure between the rotating shaft 4 and the motor 3 is simple and easy to install. The use of oil-sealed bearings can prevent the leakage of raw materials in the pulping cylinder 5 and improve the sealing effect.

[0029] Furthermore, the pulping machine also includes a second sealing structure 15 arranged in the end cover 8 and a first sealing structure 14 arranged in one end of the pulping cylinder 5 close to the front bearing chamber 12.

The first sealing structure 14 seals the gap on the front side of the rotating shaft 4 passing through the pulping cylinder 5, and the second sealing structure 15 seals the gap on the rear side of the rotating shaft 4 passing through the pulping cylinder 5. Adding the first sealing structure 14 and the second sealing structure 15 can effectively prevent the raw materials in the pulping cylinder 5 from overflowing or flowing out of the pulping cylinder 5, reduce the waste of raw materials, and increase the service life of the front bearing body 13 or the rear bearing body 10.

[0032] During actual use, the rotating shaft 4 can drive the thread of the second spiral feeding rotor 25 to rotate clockwise, and raw materials are added to the slurry cylinder 5 through the feed port 7. The second spiral feeding rotor 25 will drain and guide the raw materials entering the slurry cylinder 5 through the feed port 7, so that the raw materials are transported in the direction close to the stirring rotor 21, avoiding the accumulation of raw materials at the feed port 7 on the far left, and further avoiding the raw materials from overflowing from the gap between the rotating shaft 4 and the slurry cylinder 5 to the front bearing chamber 12, further improving the sealing and stirring effects of the utility model.
