[0021] A paper covering mechanism is installed at the left side of the upper and lower coating boarders 3, and the paper covering mechanism comprises a paper feeding roller 5, a licker-in roller 6, a guide roller 7, a crushing roller 8, and a second feeding mechanism 42. The paper feeding roller 5, the licker-in roller 6, the guide roller 7, the crushing roller 8, and the second feeding mechanism 42 are all installed on the rack 1. The guide roller 7 is arranged close to the left side of the upper and lower coating boarders 3, and the guide roller 7 is a pair of symmetrically arranged roller shafts. The paper feeding roller 5 is arranged above and left of the guide roller 7, and the paper feeding roller 5 is used for axially and horizontally sleeving the coating paper 9 in a roll on the paper feeding roller 5. The licker-in roller 6 is arranged between the paper feeding roller 5 and the guide roller 7, and the surface of the licker-in roller 6 is provided with a plurality of ring grooves along the length of the licker-in roller 6.
