Description

[Detailed Description of the Invention] "Purpose of the Invention""Industrial Application Field" This invention is a roller for coating which is coated with various synthetic resins or paints. The present invention relates to a member which can be easily taken out and is not only firmly fitted but also smoothly rotated so that synthetic resin, paint or the like does not enter the shaft hole.

"Prior Art" As a premise of this invention, the most advanced one is the registered patent No. 1599827 utility model patent (Japanese Patent Application No. 56-175814, Japanese Utility Model Publication No. 59-) also devised by the present applicant.
36311) "Coating roller" was present.

This prior invention is to demonstrate the ease of attachment / detachment of the spin coater and the shaft support and the smoothness of rotation as they are.
Since the position of the tubular cylinder is located near the middle of the shaft,
The rotation of the spin coater may be tilted to the left and right, and it is unavoidable that synthetic resin, paint, etc. enter the shaft hole and hinder the rotation.

"Problems to be solved by the device" Therefore, in the coating roller according to the present invention, the shaft hole of the rotary coating body is bottomed, and the position of the tubular cylinder of the shaft support is changed.
In addition, since the collar-shaped bearing is arranged at the root of the shaft support to eliminate these drawbacks, its details will be described below.

"Constitution of device""Means for solving problems" That is, a rotary coated body comprising a surface layer 1 made of a flexible coated body and a cylindrical core body 4 having a shaft hole 3 with a bottom 2 on one side. The shaft 10 extending from the arm 5 is provided with a bearing 10 which is adapted to be fitted into the shaft hole 3, and a circumferential groove having a slightly smaller diameter from the center of the shaft 6 toward the distal end. 7. A shaft support formed by loosely fitting an elastic tubular cylinder 9 provided with 7 and having a slightly narrowed tip and a longitudinal split 8 into the shaft so that the slightly thin tip engages with the circumferential groove. The shaft portion, which is composed of a body, is fitted into the shaft hole of the tubular core of the rotary coating body, and the bearing is also fitted into the shaft hole.

"Function" The surface layer 1 of the flexible coated body may be formed by winding a hairy band or may be formed by a porous material of synthetic resin. Of course, it is good if you can paint on things.

This coating roller comprises a surface layer 1 made of a flexible coating material and a cylindrical core body 4 having a shaft hole 3 having a bottom 2 on one side. The shaft portion 6 in which 9 is loosely fitted is inserted.

Since the tubular cylinder 9 has a slightly smaller diameter at its tip and the tip of the tubular cylinder is engaged with the peripheral hole 7 of the shaft portion, it does not fall off from the shaft portion 6 and is fitted into the shaft hole 3. Since it is easy to insert and the engagement is relatively easy, it goes without saying that it will not break down.

The tubular cylinder 9 fitted into the shaft hole has the vertical slits 8 and is elastic, so that while the peripheral surface is pressed by the hole surface of the shaft hole of the cylindrical core body 4, The hole surface is elastically pressed and integrated with the so-called cylindrical core body, and the shaft portion in the loose fitting relation is rotatable, and in the end, the rotary coating body and the shaft support body are smoothly rotatably attached. .

In this case, when the cylindrical core is made of wood, if the tubular cylinder is made of an elastic synthetic resin body, it is suitable for frequent use without damaging the cylindrical core when attaching and detaching. Is.

Further, if the diameter of the tubular cylinder is made relatively large or the thickness thereof is increased, the integration with the cylindrical core becomes strong.

Moreover, in the present invention, since the circumferential groove 7 is provided from the center of the shaft portion 6 toward the front end direction, the tubular cylinder 9 engaged therewith has the bottom of one of the shaft holes 3 of the cylindrical core body. Since the bearing 10 inserted in the vicinity of the shaft portion 6 extending to the arm portion 5 is fitted into the inlet of the shaft hole, the shaft portion 6 is arranged between the tubular cylinder 9 and the bearing 10. It is pivotally supported in two places, and its rotation is smooth and unbiased. And, various synthetic resins and paints attached to the rotary coating body have one of the shaft holes 3 of the cylindrical core closed by the bottom 2, and the bearing 10 is inserted into the other inlet of the shaft hole. Since it exists, it does not penetrate into it.

When pulling out the shaft support from the rotary coating body, it is sufficient to simply pull it out, and since the tubular cylinder only presses the hole surface of the shaft hole by its elasticity, it is not necessary to remove the screw, The bearing 10 which is inserted into the shaft portion 6 and fitted into the entrance of the shaft hole is also removed.

[Example] In the example, the diameter of the shaft portion was about 6 mm, the outer diameter of the tubular cylinder was about 12 mm, and the outer diameter of the bearing was 11.8 mm. As shown in FIG. 4, the tubular cylinder may be thickened in a tapered shape from the front end to the rear end 11.

Note that the size is not limited to this, and it goes without saying that the size may be appropriately configured.

"Effects of the device" As described above, the coating roller according to the present invention applies various synthetic resins and paints adhered to the surface layer of the flexible coated object of the rotating object onto the object while rotating very smoothly. It is a highly practical device that can be attached and removed, and the rotary coating and the shaft support can be attached and detached without complicated operations, and that synthetic resin and paint do not enter the shaft hole and do not hinder rotation.
