Embodiment Construction

[0009] Such as figure 1 , figure 2 As shown, a sizing roller includes a sizing roller body 1, a circle of sinking grooves 2 are respectively arranged on the inner sides of the two ends of the sizing roller body 1, and a disc-shaped fixed sleeve 3 is arranged on the sinking groove 2, and the fixed shaft The sleeve 3 is fixed on the sizing roller body 1 by bolts 4 . By processing an inner sinking groove 2 at both ends of the sizing roller body 1, the fixed sleeve 3 can adopt a disk shape and be fixed on the sizing roller body 1 by bolts 4, which neither increases the thickness of the two ends of the sizing roller body 1 nor reduces the The quality of the fixed shaft sleeve 3 is improved, the overweight phenomenon is avoided, and the service life of the equipment is improved.

Abstract

The invention relates to an applicator roll, which can be used for solving the problems that the thickness of the end part of the applicator roll can not be increased, and only a fixing shaft sleeve is installed in the roll to be connected with a shaft. The applicator roll comprises an applicator roll body and is characterized in that ring sinking grooves are respectively formed on the inner sides of the two ends of the applicator roll, and are provided with disc-shaped fixing shaft sleeves, and the fixing shaft sleeves are fixed on the applicator roll body by a bolt. According the applicator roll, the weight of the applicator roll is lightened, the service lives of other devices can be prolonged, and simultaneously, the thickness of the end part of the applicator roll is not increased.

Description

technical field [0001] The invention relates to a sizing roller. Background technique [0002] The sizing roller is used to add some sizing material on the surface of the wet paper to improve the quality of the paper, especially to improve the napping, printing, and reduce the stain on the paper surface, and to improve the smoothness of the paper, so the end of the sizing roller It is not allowed to increase the thickness of the sizing roller. It can only be connected to the shaft by inserting a fixed bushing at both ends of the sizing roller. Under long-term high-speed operation, it is easy to cause short service life of other equipment due to being too heavy. Contents of the invention [0003] The purpose of the present invention is to provide a sizing roller to solve the problem that the thickness of the end of the sizing roller can only be connected with the shaft by installing a fixed sleeve in the roller. [0004] The technical solution adopted by the present inven...
