Problems solved by technology

Since the known core of the squeeze roller is made of rigid material, only the roller cover on the surface has a certain degree of elasticity, and the contact between the squeeze roller and the steel belt is not very close during use, especially after repeated use of the roller cover. After being ground and thinned, it has a certain impact on product quality and a shorter service life

Embodiment Construction

[0011] Please see attached figure 1 , the known rigid roll core (5) of the squeeze roll is made of rigid material, and only the roller sleeve (4) on the surface has a certain elasticity, so the squeeze roll and the steel strip (1) are not in contact with each other during use. It is very tight, so it has a great impact on product quality. Simultaneously, once the axle sleeve (4) is used several times and ground and cut thin, the contact between the squeeze roller and the steel strip is very poor, and the squeeze roller has to be scrapped, and the service life is also shorter.

[0012] exist figure 2 In a specific embodiment of the invention shown: the roller shaft (2) is a long shaft.

[0013] In another specific embodiment of the present invention, elastic material is wrapped on the roller shaft (2) to make the elastic roller core (3), which can be deformed under the action of external force.

[0014] please see image 3 , an embodiment of the present invention is instal...

Abstract

The invention provides an elastic drying roll. In the drying roll, the roll shaft is a full-length shaft, wherein an elastic material is coated on the roll shaft to manufacture a roller core; and a wear and elastic roll sleeve is coated outside the roller core. When the elastic drying roll is used, the roller core and the roll sleeve on the surface have elasticity, so the whole body is deformed into an elliptic shape, thereby increasing the compact degree of the drying roll and a steel strip and improving the product quality. Furthermore, even the roll sleeve is repeatedly used, grinded and thinned, the drying effect is not greatly influenced, so the service life of the drying roll can be prolonged.

Description

Technical field [0001] The invention relates to a device for squeezing out moisture on the surface of a steel strip, in particular to an elastic strip surface moisture squeezing roller. Background technique [0002] At present, the known squeeze roll structure is composed of a shaft head, a roll core and a roll sleeve on the surface. The roller shaft is disconnected, so there are two shaft heads, which are welded to both ends of the roller core for installing bearings and transmitting power. The roller core is a long cylinder made of rigid materials such as steel. The core is wrapped with a roller sleeve, which is generally a rubber layer with certain wear resistance and elasticity, and becomes a squeeze roller. Squeeze rollers are used in the steel strip production line in steel factories. When there is moisture on the surface of the steel strip and must be removed, install a squeeze roller on each side of the steel strip, and apply opposite pressure to them to squeeze the...
