[0002] The vacuum roller, also known as the vacuum couch roller, is a key equipment in the papermaking industry, especially in the paper production process. It is a hollow roller with many small holes on the surface, through which air can be extracted to form a vacuum environment. When the pulp passes through the couch roller, the water in the pulp is extracted due to the vacuum, and the paper is adsorbed on the surface of the roller to form a continuous paper belt. Its main functions include dehydration, forming, conveying, etc. The maintenance and adjustment of the vacuum couch roller in the papermaking process is very important for producing high-quality paper.

[0003] During use, the vacuum roller usually needs to be fixed in a specified position to cooperate with production.

The positioning plate 521 is connected to the end of the telescopic cylinder 51, and a fixed shaft 522 is connected to the bottom of the positioning plate 521. A turntable 523 is provided at the bottom of the fixed shaft 522. A plurality of balls 524 are installed on the upper and lower sides of the turntable 523. The roller assembly 53 rotates at the bottom of the positioning assembly 52.

[0041] Specifically, a plurality of balls 524 are arranged in a circle on the upper and lower sides of the turntable 523 , and the positioning plate 521 rotates at the end of the telescopic cylinder 51 .

[0042] Specifically, the roller assembly 53 includes a rotating box 531, a rotating hole 532 is opened at the top of the rotating box 531, a turntable 523 is accommodated inside the rotating box 531, and the ball 524 rolls on the upper and lower inner walls inside the rotating box 531, and a plurality of weight-reducing holes 533 are opened on the outer wall of the rotating box 531. A fixed mounting bridge 534 is connected to the bottom of the rotating box 531, and a shaft 535 is clamped at the bottom of the fixed mounting bridge 534, and a roller 535 is installed on the shaft 535.

[0043] Specifically, a plurality of weight-reducing holes 533 are evenly spaced and arranged on the outer wall of the rotating box 531 .

[0044] In this embodiment, the positioning assembly 52 (including the positioning plate 521 and the fixed shaft 522) of the telescopic cylinder 51 is assembled in the mounting hole 31 of the mobile base 3, and the positioning plate 521 is matched with the positioning groove 34, and the roller 531 is installed on the fixed mounting bridge 534 at the bottom of the turntable 523.
