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

A kind of application roll

Technical field

the present invention relates to a kind of application roll.

Background technology

application roll is to be used on wet paper surface, increases some sizing materials, to improve the quality of paper; Particularly improve plucking property, printing, and reduce the paper surface stain; With improve smoothness of paper, so the application roll end do not allow to increase thickness, can only through fill at the application roll two ends fixed hub realize with spool be connected; But the big quality of fixed hub volume is big, increases facility load, also causes the problem that lays particular stress on easily; Run up for a long time down at application roll, easily because remake into very much the short problem of other service life of equipments.

Summary of the invention

the object of the present invention is to provide a kind of application roll, and solution application roll end can not increase thickness can only be through installing and fixing the problem that axle sleeve is connected with axle in roller.

the technical solution adopted for the present invention to solve the technical problems is: a kind of application roll; Comprise the application roll body; It is characterized in that; Inboard, described application roll two ends is respectively equipped with a circle deep gouge, and deep gouge is provided with the plate-like fixed hub, and fixed hub is through being bolted on the application roll body.

the invention has the beneficial effects as follows: alleviate application roll weight, prolong the service life of other equipment, also do not increase the application roll end portion thickness simultaneously.

Description of drawings

Fig. 1 is a structural representation of the present invention,

Fig. 2 is the right view of Fig. 1.

Among figure: 1 application roll body, 2 deep gouges, 3 fixed hubs, 4 bolts.

The specific embodiment

are like Fig. 1, and are shown in Figure 2, a kind of application roll; Comprise application roll body 1; Inboard, described application roll body 1 two ends is respectively equipped with a circle deep gouge 2, and deep gouge 2 is provided with plate-like fixed hub 3, and fixed hub 3 is fixed on the application roll body 1 through bolt 4.Through inner groove 2 of processing at application roll body 1 two ends; Fixed hub 3 can adopt plate-like and be fixed on the application roll body 1 through bolt 4; The thickness that neither increases application roll body 1 two ends has alleviated the quality of fixed hub 3 again, has avoided laying particular stress on phenomenon, has improved the service life of equipment.

Claims (1)

1. an application roll comprises the application roll body, it is characterized in that, inboard, described application roll body two ends is respectively equipped with a circle deep gouge, and deep gouge is provided with the plate-like fixed hub, and fixed hub is through being bolted on the application roll body.
