Synchronous operation comprehensive non-woven fabric oil squeezing roller

Technical Field

The utility model relates to the field of rolling production of cold-rolled sheet strips, in particular to a synchronous running comprehensive non-woven fabric oil squeezing roller.

Background

The non-woven fabric oil squeezing roller is one of indispensable components in the rolling production process of the cold-rolled sheet and strip, and is mainly applied to the production industries of stainless steel cold-rolled sheet and strip, copper alloy sheet and strip, aluminum sheet and strip, automobile sheet, household appliance sheet, textile printing and dyeing and the like. Because of the different application industries, users have different requirements on dead weight, installation occasions, rotating speed and the like of the non-woven fabric oil squeezing roller. The method comprises the following steps:

firstly, the dead weight of the oil squeezing roller influences the clamping degree of the plate belt. The plate and strip materials produced by users have different thicknesses and widths, and the tension properties of the materials of different materials are different. Therefore, different requirements exist for the clamping force provided by the non-woven fabric oil squeezing roller in production. In actual production, the pressure provided by the hydraulic cylinder to the roller and the gravity applied by the roller together form positive pressure on the plate belt, and the positive pressure is a main factor affecting the clamping force of the plate belt.

Secondly, the installation site conditions determine the structural form of the oil squeezing roller. The installation of the oil squeezing roller is required to meet the working condition demands of the user on site. When the non-woven fabric oil squeezing roller is used, a bearing needs to be assembled, the bearing is usually arranged at the shaft head positions at the two ends of the mandrel, the bearing needs to be matched with a bearing seat and a supporting frame, and the installation position is required to have enough space and distance conditions.

Third, the roller speed affects the quality and production efficiency of the strip. The rotating speed of the oil squeezing roller is synchronously matched with the running speed of the plate belt, and the surface of the plate belt is free from defects of scratch, vibration patterns and the like which affect the quality, so that the plate belt production has the condition of accelerating.

The existing non-woven fabric oil squeezing roller has some defects, such as insufficient lubrication of bearings at two ends; the vibration of the roller can cause loosening of screws, so that oil leakage of the bearing is damaged; the movable bearings of some oil squeezing rollers are not easy to disassemble; the previous non-woven fabric oil squeezing roller and the steel belt do not run synchronously, so that the problems of sideslip, long coil and the like of the steel belt can occur. Therefore, there is a need for an improvement to existing nonwoven fabric oil squeeze rolls that not only meets the above-mentioned needs but also ameliorates the existing problems.
