[0023] Specifically: the hydraulic cylinder 2 can control the use angle of the supporting arm 1, so that the roller can stably pressurize the drying cylinder. The standing column 4 is fixed to the top of the frame body 3 by screws. The pull-out block 7 can be sealed with the openings at the bottom of both sides of the frame body 3. The supporting arm 1 can facilitate the installation and fixation of the roller.

[0024] Example 2

[0025] See also Figure 1-2 On the basis of Example 1, the bottom of the withdrawal block 7 is fixedly connected to the frame body 3 by bolts, and the opposite sides of the two supporting arms 1 are movably connected to the frame body 3 through the first bearing. The two sides of the hydraulic cylinder 2 are movably connected to the supporting arm 1 and the frame body 3 through the second bearing. The bottom of the front and rear sides of the inner cavity of the frame body 3 are fixedly connected to the mounting seat installed in conjunction with the hydraulic cylinder 2. A conveying opening is provided at the top of the right side of the station column 4, and a limit block is provided in the inner cavity of the conveying opening. The bottom of the pull rod 6 is threadedly connected to the support seat, and a threaded hole is provided at the bottom of the support seat. The surface of the withdrawal block 7 is fixedly connected to a handle.

[0026] Specifically: the bolt can facilitate the positioning of the withdrawal block 7 to prevent it from escaping from the opened inner cavity; the first bearing can enable the support arm 1 to swing, making it convenient to adjust the use position of the roller; the second bearing can facilitate the hydraulic cylinder 2 to adjust the use angle of the support arm 1, making it convenient for the roller to regulate the pressure of the drying cylinder; the mounting seat can facilitate the installation and fixation of the hydraulic cylinder 2; the support seat can increase the stability of the pull rod 6 support; the threaded hole can facilitate the installation and fixation of the support seat; and the handle can facilitate the staff to pull out the withdrawal block 7.

[0027] The working principle of the present invention is as follows: when the blanket needs to be replaced, the hydraulic cylinder 2 is turned on, and the hydraulic cylinder 2 cooperates with the supporting arm 1 to drive the roller to no longer apply pressure to the drying cylinder, so that the two are no longer in contact. Then the staff cuts and removes the blanket, and then presses the cantilever beam 5 through the pull rod 6 and pulls out the pull-out block 7 through the handle. Then the staff installs the new blanket on the frame body 3 and the roller. The whole process is fast and convenient, which improves the efficiency of replacing the blanket, saves time, and reduces labor intensity. After the blanket is installed, the hydraulic cylinder 2 is turned on, and the hydraulic cylinder 2 drives the supporting arm 1 and the roller to move, so that the roller contacts the drying cylinder and pressurizes it, which improves the stability of the structure and the stability of the pressurization. When replacing the blanket, it can also be operated quickly and conveniently, which is convenient for the staff to use and improves production efficiency.
