Description

Technical Field

[0001] The invention relates to the technical field of cold rolling in the metallurgical industry, and in particular to an oil removal device at an inlet of an oil coating machine. Background Art

[0002] With the continuous development of hot-dip galvanizing product production technology, in addition to the basic requirements for strip surface quality and performance, customers increasingly require that the strip surface be oiled to improve its performance. The electrostatic oiler is a key device for applying high-quality anti-rust oil to the strip surface to prevent corrosion. It relies on the effect of high-voltage electrostatic field and the influence of tip discharge to quickly atomize the oil flowing out of the gap between the blade beams and adsorb it on the surface of the strip to form a uniform and thin oil film; it prevents scratches caused by direct friction between layers during the strip coiling process. At the same time, the oil film has a certain anti-corrosion performance that can effectively prevent rust on the strip surface during storage and transportation.

[0003] In the actual production process, the strip steel at the exit needs to be rewound for production quality review, etc. At this time, the strip steel with oil on the surface will pass through the tension roller. The tungsten carbide roller surface of the tension roller will be contaminated with grease, resulting in a decrease in the friction coefficient of the roller surface. In severe cases, the tension roller will slip during normal production. In this production process, it is necessary to remove the oil film on the surface of the strip steel. Summary of the invention

[0004] In view of the above-mentioned defects in the prior art, an oil removal device is provided at the inlet of an oiler. Together with the subsequent blowing device, the grease on the surface of the strip can be effectively removed when the strip needs to be rewound at the steel outlet, thereby preventing the tension roller from being contaminated with grease and affecting the normal production of the unit.

[0010] According to the above technical solution, the driving assembly includes a linear power unit and a connecting unit. The linear power unit is arranged vertically and is divided into a fixed part and a movable part. The movable part moves linearly relative to the fixed part. One end of the linear power unit is fixed on the frame, and the other end is connected to the upper surface of the upper beam or the lower surface of the lower beam through the connecting unit.

[0011] According to the above technical solution, the linear power unit adopts a pneumatic cylinder, an oil cylinder, and an electric push rod.

[0013] According to the above technical solution, the oil-absorbing wrapping layer is wrapped around the upper crossbeam and the lower crossbeam within the width range of the strip.

[0014] According to the above technical solution, the oil-absorbing wrapping layer is made of oil-absorbing wool felt.
