Description

Technical Field

[0001] The utility model relates to the technical field of zinc, aluminum and magnesium product processing equipment, and more specifically to a device for solving the problem of scratches on the outlet of a thick material cleaning section. Background Art

[0002] In today's society, the competition for cold-rolled zinc-aluminum-magnesium products is fierce. All manufacturers are working hard to improve product quality and enhance the market competitiveness of their products. In surface quality control, scratches on the surface of zinc-aluminum-magnesium steel sheets appear in the early stage of production, which has a great impact on the improvement of product quality. Through repeated investigations and confirmations, thick materials generally have C-type curvature, and the thicker the strip, the more serious the curvature. When the strip with curvature passes through the exit of the cleaning section and enters the drying bellows, it is easy to scratch against the inner wall of the drying bellows, causing damage to the plate surface. After the strip is damaged, it will cause scratches on the surface after hot-dip galvanizing and aluminum-magnesium. Therefore, in view of this, the existing structure is studied and improved, and a set of devices to solve the scratches at the exit of the thick material cleaning section is provided, in order to achieve a more practical purpose.

[0007] A device for solving the scratching of the thick material cleaning section outlet comprises a cleaning group, a drying bellows and a steel strip, wherein the steel strip passes through the cleaning group and the drying bellows in sequence, and a stabilizing mechanism is arranged between the cleaning group and the drying bellows;

[0008] The stabilizing mechanism comprises a roller frame, on which are mounted two groups of symmetrically arranged top screw adjustment assemblies, on which are fixedly mounted two bearing seats, between which a stabilizing roller is rotatably connected, and the two stabilizing rollers are symmetrically arranged on both sides of the strip.

[0009] Furthermore, the top screw adjustment assembly includes a guide rail fixed on the roller frame, the outer periphery of the guide rail is slidably connected to a traction frame, one end of the traction frame is rotatably connected to a screw rod, one end of the screw rod extends to the outside of the roller frame and is fixedly connected to an adjustment nut.

[0010] Furthermore, threaded holes are provided at both ends of the roller frame, and the roller frame is threadably connected to the outer circumference of the corresponding screw rod through the threaded holes.

[0011] Furthermore, the two bearing seats are fixedly mounted on the traction frame and are symmetrically arranged at two ends of the traction frame.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] This solution adds a set of rubber roller stabilizing rollers at the entrance of the drying bellows and uses the top wire adjustment assembly to adjust the position of the stabilizing rollers. It can not only reduce the C-shaped deflection of thick strip steel, but also control the jitter caused by poor strip shape. At the same time, it makes the strip pass through the center of the gap of the drying bellows as much as possible to avoid contact between the two, thereby eliminating the scratch defects of zinc, aluminum and magnesium products caused by the poor shape of incoming materials rubbing against the drying bellows in the cleaning section.
