During the rotation of the bracket 403, the bracket 403 can contact the eccentric frame 405 to make it rotate to a certain extent, and the fixed angle of each group of brackets 403 is different. A spring shaft 404 is arranged below the side of the vacuum box 1 relative to the support shaft 402. The spring shaft 404 can reset the eccentric frame 405. The eccentric frame 405 is fixed on the outside of the spring shaft 404. During the rotation of the eccentric frame 405, it collides with the adsorption mold 2 to cause it to vibrate, and one end of the eccentric frame 405 is located at the rotating outer diameter of the bracket 403.

[0025] like Figure 2 As shown, a connecting port 5 is installed at the top of the adsorption mold 2, and the connecting port 5 is connected to the vacuum pump 3 through the exhaust pipe 6, so that the vacuum pump 3 can be connected to the adsorption mold 2 through the exhaust pipe 6 and the connecting port 5, and can be moved to the adsorption mold 2 for vacuum treatment.

[0026] like Figure 1-Figure 2 As shown, an exhaust pipe 7 is installed at the top of the vacuum pump 3 , and the top of the exhaust pipe 7 passes through the top of the vacuum box 1 , so that the gas extracted by the vacuum pump 3 can be discharged through the exhaust pipe 7 .

[0027] like Figure 1 , Figure 2 and Figure 4As shown, sealing mechanisms 8 are symmetrically arranged on both sides of the vacuum box 1 , and the sealing mechanism 8 includes a rotating motor 801 , a connecting shaft 802 , a sealing door 803 and a sealing gasket 804 , so as to facilitate sealing of both sides of the vacuum box 1 through the sealing mechanism 8 .

During use, the eccentric frame 405 can rebound quickly through the spring shaft 404, and because the installation angles of each group of brackets 403 are different, the eccentric frame 405 can be continuously in contact with the adsorption mold 2. After the vacuum treatment is completed, the sealing mechanism 8 on the other side is opened to take out the fiber through an external manipulator for subsequent processing.
