Therefore, the bottom of the front pressing plate 274 can be kept in abutment with the top of the cap, and the pressure applied by the first pressure adjusting box 281 can be adjusted by adjusting the deformation amount of the third elastic sheet.

[0056] When the cap is hung, the cap is sent from the hopper screen into the chute of the heating mechanism 10. When the cap flows through the chute, it enters the steam heating part. The lower part of the steam pipe 14 has two rows of small holes. High-temperature steam is sprayed from the holes to heat the cap and the internal sealing glue to a certain temperature. After the cap is heated and expanded, it enters the guide groove 221 of the cap hanging mechanism 20. The inside end of the guide groove 221 is provided with a movable top block 24. After the cap enters, it will be clamped and not allowed to fall. At the same time, the conveying belt conveys the bottle to the position below the movable top block 24. The left and right bottle protection triangular belts on both sides of the conveying belt clamp the bottle to smoothly pull out the cap from the bottle mouth. Then, the cap is pre-rotated into the bottle mouth part by the cap rubbing assembly 27 and the cap rubbing piece 272 on the side, so as to finally realize the cap hanging process.
