Description

Technical Field

[0001] The utility model relates to the technical field of leveling machines, in particular to a purge structure of a leveling machine for cold-rolled strip steel production. Background Art

[0002] Cooling lubrication is one of the core technologies of cold rolling. During the rolling process, a certain amount of emulsion must be sprayed on the rollers and strips to ensure stable production. Therefore, a certain amount of emulsion remains on the surface of the strip after rolling during the production process.

[0003] A purge structure for a cold-rolled strip production leveler with announcement number CN 211538993 U is provided. The compressed gas connected to the compressed air port is discharged through a sheet-shaped air outlet through an air duct pipeline and an air curtain plate outlet. A sheet-shaped high-strength air curtain is formed toward the end of the air curtain plate opening, thereby performing high-pressure blowing on the surface of the cold-rolled strip. The rotation of the vortex impeller in the structure reduces the loss of air flow, thereby reducing the gas consumption of the structure.

[0004] However, this patent still has some shortcomings when used. When the emulsion on the surface of the workpiece is purged, since the emulsion is not cleaned before the purging, the purged substance is a mixture of the emulsion and the detergent, and the mixture will be adsorbed on the strip. Therefore, the wind needs to be concentrated in one place for purging, so the air outlet needs to be adjusted. Since a certain amount of emulsion is also added to the leveling roller of the leveling machine, the leveling roller also needs to be cleaned, and the cleaning roller needs to be removed, cleaned, and then installed for use, which is a cumbersome process.

[0028] Among them, the height and direction of the blowing device are adjusted by setting a first electric telescopic rod 5, a first connecting block 6, a first rotating block 7 and an adjusting device 3. By controlling the extension and retraction of the first electric telescopic rod 5, the blowing device can be suitable for strip steels of different thicknesses. By controlling the extension and retraction of the second electric telescopic rod 303, the first rotating block 7 rotates with the bellows 8, thereby adjusting the direction of the air outlet of the bellows 8.

[0029] In this embodiment, Figure 1 , Figure 4 and Figure 5 As shown, both sides of the bellows 8 are fixedly connected with wind shields 15, the inclination angle of the wind shields 15 is 30 degrees, the material of the wind shields 15 is stainless steel, the inside of the bellows 8 is fixedly connected with a ventilation net 16, the ventilation net 16 adopts an air filter with an aperture of 300 meshes, the material of the ventilation net 16 is PC plastic, the bottom of the bellows 8 is fixedly connected with a wind deflector 17, the inside of the wind deflector 17 is rotatably connected with a plurality of guide pieces 18, the guide pieces 18 are thick in the middle and thin on both sides and have a certain curvature, and the material of the guide pieces 18 is an aluminum alloy that is not easily deformed.
