DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following further describes the embodiments of the present utility model with reference to the drawings:

[0019] Embodiment 1:

[0020] As Figures 1 to 4 shown, the anti-vibration structure of the paper web of the cultural paper production paper machine described in the present utility model includes a mounting seat 1. A row of support frames 3 are fixedly connected to the top of the mounting seat 1. Guide sleeves 4 are fixedly connected to each support frame 3. Guide rods 5 are slidably connected in each guide sleeve 4. A wind baffle 10 is fixedly connected between the upper ends of each guide rod 5. Support seats 2 are fixedly connected to the left and right sides of the top of the mounting seat 1. A rotating shaft 13 is rotatably connected between the two support seats 2. The rotating shaft 13 is connected with a rotation driving assembly and a locking assembly. First swing arms 14 corresponding to the guide rods 5 are fixedly connected to the rotating shaft 13. Second swing arms 15 are hinged between each corresponding guide rod 5 and the first swing arm 14.

[0021] When in use, as Figure 5As shown in the figure, the device is fixedly installed below the arc-shaped roller 20 after sizing through the mounting base 1. When the paper is widened and led, the wind deflector 10 is in the lower limit position. At this time, the distance between the wind deflector 10 and the arc-shaped roller 20 after sizing is large, so it will not interfere with the operation of widening and leading the paper. During the normal production of coated paper, the rotating drive assembly drives the rotating shaft 13 to rotate, thereby driving a plurality of first swing arms 14 to turn upwards, and then driving a plurality of guide rods 5 to rise synchronously under the guiding action of the guide sleeves 4 through the respective second swing arms 15, so as to raise the wind deflector 10 to a suitable position. The locking assembly can lock the rotating shaft 13, thereby realizing the positioning of the wind deflector 10. At this time, the airflow generated in the subsequent drying process flows out from below the wind deflector 10, so it will not directly impact the paper web, effectively preventing the paper web from shaking.

[0022] The anti-shaking structure of the paper web of the coated paper production paper machine described in the present utility model is provided with a wind deflector 10, which can block the airflow generated in the subsequent drying process, effectively preventing the shaking phenomenon of the paper web caused by the airflow when the paper web runs to the arc-shaped roller 20 after sizing, thereby preventing the paper web from breaking and ensuring the production efficiency of the coated paper.

[0023] Embodiment 2:

[0024] As Figures 1 to 5 shown, on the basis of Embodiment 1,

[0025] Furthermore, the rotating drive assembly includes a through hole provided through one end of the rotating shaft 13, and a handle 18 is inserted into the through hole. By rotating the handle 18, the rotating shaft 13 can be driven to rotate, with a simple structure and convenient operation.

[0026] Furthermore, the locking assembly includes a ratchet tooth 16 hinged to one of the support seats 2 and a ratchet wheel 17 fixedly connected to the rotating shaft 13. The ratchet wheel 17 is correspondingly adapted to the ratchet tooth 16. Through the cooperation of the ratchet wheel 17 and the ratchet tooth 16, the reverse rotation of the rotating shaft 13 can be prevented, thereby realizing the locking of the rotating shaft 13, with a simple structure and stable operation.

[0027] Furthermore, a connecting plate 6 is welded to the upper end of the guide rod 5. A strip-shaped hole 7 is provided on the connecting plate 6. The wind deflector 10 is provided with screws 8 corresponding to the strip-shaped holes 7 one by one. The screws 8 pass through the strip-shaped holes 7 and are connected with nuts 9. The fixed connection between the guide rod 5 and the wind deflector 10 is realized through the cooperation of the screws 8 and the nuts 9, which is convenient for installation and disassembly. At the same time, the screws 8 are equipped with strip-shaped holes 7, which can eliminate the assembly error and make the assembly between the guide rod 5 and the wind deflector 10 simpler.

[0028] Furthermore, a smooth round tube 11 is connected to the top of the wind deflector 10, which can effectively prevent the wind deflector 10 from scratching and damaging the paper web and plays a protective role.

[0029] Further, a plurality of clamping plates 12 are connected between the smooth circular tube 11 and the wind shield 10, and the clamping plates 12 can increase the structural stability of the smooth circular tube 11.

[0030] It should be specifically noted that: in the description of the present invention, the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention rather than requiring the present invention to be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.
