Abstract
The utility model discloses a full rubber-coated passivation roller, include the roll body and fix first back shaft, second back shaft and the bearing installation axle at the roll body both ends, first back shaft constitutes the stair structure with the second back shaft, the surface of roll body, the side end face of roll body, the surface of first back shaft, the side end face of first back shaft and the surface of second back shaft all are provided with acid and alkali-resistant glue film. The utility model discloses a coating acid and alkali-resistance glue film of large tracts of land has avoided the direct contact of passivation liquid with the passivation roller, great extension the life of passivation roller, reduced manufacturing cost to output has been improved.
Description
Technical Field
The utility model relates to a board production facility technical field of precoating especially relates to a formula passivation roller is glued to package entirely.
Background
Passivation is an important step in galvanized steel pipe production, the purpose is to make its metal surface turn into the state of being difficult for oxidizing, and passivation roller is the essential important part in passivation, passivation roller generally refers to be used for scribbling the material roller and the sizing roller with passivation liquid contact, as shown in figure 1, because passivation liquid exists corrosion, generally all carry out rubber coating on the roll body and handle, be provided with acid and alkali-resistant glue film 1-2 on the surface of roll body 1-1, but passivation liquid can uncontrollably appear the phenomenon of splashing or flow on back shaft 1-3 along acid and alkali-resistant glue film 1-2 in the high-speed running process, cause the corruption to the back shaft, thereby the cracked phenomenon appears, serious influence passivation roller's life, not only increased use cost, and reduced production efficiency.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to avoid prior art's weak point, provide a formula passivation roller is glued entirely to effectively solve the weak point that exists among the prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a totally encapsulated passivation roller, includes the roll body and fixes first back shaft, second back shaft and the bearing installation axle at the roll body both ends, first back shaft and second back shaft constitute stair structure, the surface of roll body, the side end face of roll body, the surface of first back shaft, the side end face of first back shaft and the surface of second back shaft all are provided with acid and alkali resistant glue film.
Further, be provided with first annular on the first support shaft, acid and alkali-resistant glue film fills first annular.
Further, the first ring groove is provided with a position which is arranged in the middle of the first support shaft.
Further, be provided with the second annular on the second back shaft, acid and alkali-resistant glue film fills the second annular.
Further, the second annular groove is provided with two places, and the two places second annular groove sets up about second back shaft symmetry.
The above technical scheme of the utility model following beneficial effect has: the utility model discloses a coating acid and alkali-resistance glue film of large tracts of land has avoided the direct contact of passivation liquid with the passivation roller, great extension the life of passivation roller, reduced manufacturing cost to output has been improved.

Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1, the passivation roller of full rubber-coated type described in this embodiment includes roll body 1 and fixes first support shaft 2, second support shaft 3 and bearing installation axle 4 at roll body 1 both ends, and first support shaft 2 constitutes stair structure with second support shaft 3, and roll body 1's surface, roll body 1's side end face, first support shaft 2's surface, first support shaft 2's side end face and second support shaft 3's surface all are provided with acid and alkali-resistant glue film 5.
The utility model discloses a coating acid and alkali-resistance glue film 5 of large tracts of land has avoided the direct contact of passivation liquid with the passivation roller, great extension the life of passivation roller, reduced manufacturing cost to output has been improved.
Be provided with first annular 2a on the first support shaft 2, acid and alkali-resistant glue film 5 fills first annular 2a, and first annular 2a is provided with one, and it sets up in the middle part of first support shaft 2.
Be provided with second annular groove 3a on the second back shaft 3, acid and alkali-resistant glue film 5 fills second annular groove 3a, and second annular groove 3a is provided with two places, and two places second annular groove 3a sets up about 3 symmetries of second back shaft.
Through setting up first annular 2a and second annular 3a, can further improve the adhesion of acid and alkali-resistant glue film 5 and passivation roller.
The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
