Description

Oil removing roller

Technical Field

The utility model relates to a sheet metal processing equipment, more specifically say, it relates to an deoiling roller.

Background

In order to improve the speed and stability of a rolling mill, reduce the rolling moment and reduce the surface temperature of a roller in a nonferrous metal cold rolling unit, the rolling process adopts full-oil process lubrication, which is the requirement of the rolling process, but the rolling oil on the surface of a strip needs to be removed in a finished product coil, otherwise, the strip is easy to slip during coiling, and a large amount of rolling oil after annealing pollutes the surface quality of the strip and affects the surface quality of a product. On modern high-precision nonferrous metal rolling mills, the rolling oil residue on the surface of the strip determines the production efficiency of the whole mill and the quality of the finished strip. The rolling speed is low, the productivity cannot be brought into play and the production cost is high due to the fact that rolling oil cannot be removed completely and the surface residual oil quantity is large when the high-precision nonferrous metal strip is rolled frequently.

SUMMERY OF THE UTILITY MODEL

To the not enough of prior art, the utility model aims to provide a can high-efficient degreasing roller.

In order to achieve the above purpose, the utility model provides the following technical scheme:

an oil removing roller comprises a shaft tube and a roller; the roller is rotatably sleeved outside the shaft tube, and two ends of the shaft tube are connected with a vacuum suction device; the shaft tube is provided with an air suction opening, and vent holes are uniformly distributed on the roller; the two ends of the roller are fixed through fasteners, and the air suction opening is rotatably provided with a pulley abutted against the inner wall of the roller.

According to the arrangement, after the vacuum suction device is started, negative pressure is generated at the outlet of the suction opening, and after the plate passes through the oil removing roller and is in contact with the roller, oil stains enter the shaft tube through the vent hole, so that the oil removing effect is achieved; the pulley provides support between the roller and the shaft tube to prevent the roller surface from deforming under stress.

Further setting: the edge of the air suction opening is provided with a surrounding edge, and the periphery of the surrounding edge is provided with a wheel seat which is rotatably connected with the pulley.

So set up for the pulley can stabilize the rotation and connect on the surrounding edge.

Further setting: the fastener comprises a bearing and a bearing sleeve, wherein the inner ring of the bearing is sleeved on the outer circumferential wall of the shaft tube, and the inner circumferential wall of the bearing sleeve is sleeved on the outer ring of the bearing; and the two ends of the roller are connected with the bearing sleeve through bolts.

So set up for the cylinder can be installed on the central siphon firmly and rotate steadily.

Further setting: and a limiting ring for abutting the end face of the bearing is arranged on the inner peripheral wall of the bearing sleeve.

So set up for bearing housing and bearing installation are accurate.

Further setting: and a reinforcing rib is arranged between the periphery of the surrounding edge and the peripheral wall of the shaft tube.

So set up, make the pulley when the atress, suction opening is out of shape through setting up the strengthening rib.

To sum up, the utility model has the advantages of it is following:

1. the oil removing roller has a reliable structure and is stably installed;

2. the oil removing roller can suck away the oil stains on the surface of the plate through the negative pressure generated by the vacuum suction device, and the oil removing effect is good.
