Description

Rotary roller surface contaminant removal device using cleaning member {APPARATUS FOR CLEANING SURFACE OF ROLLER USING CLEANING MEMBER}

The present invention relates to a contaminant removal device, and more particularly, to a device for efficiently removing contaminants attached to the surface of a rotating roller using a cleaning member.

In general, the surfaces of various rollers used in production sites such as steel mills, paper manufacturing, printing, film, food, and chemical factories are stained with various types of contaminants such as cooling water, scale, dust, oil, etc., depending on the manufacturing process and working environment. .

These contaminants cause marks and contamination on the surface of the product passing through the roller, which eventually causes product defects. In addition, when the facility is operated for a long time in a state in which contaminants are adhered to the surface of the roller, the surface of the roller is easily damaged and damaged.

Accordingly, a roller surface contaminant removal device capable of removing contaminants from the surface of the roller is used. 1 is a schematic view of a conventional contaminant removal device. As shown, in the conventional contaminant removal device 10, the blade 11 contacts the surface of the roller A at an angle at an angle to remove the contaminant B from the surface of the roller A.

However, in the conventional roller surface contaminant removal device 10, the contaminant B separated from the surface of the roller A by the blade 11 is deposited on the surfaces of the peripheral equipment and the blade 11 and the blade holder 13. As it sticks, it is difficult for the operator to replace and maintain the blade.

That is, when contaminants (B) adhere to the peripheral equipment and blade holder 13, the operator must individually crush the contaminants. It is necessary to stop the operation, so economic loss occurs due to the suspension of operation.
