[ The outer diameter enlarging portion 130 is installed on the outer circumferential surface of the roller 110 so that the steel plate coil 2 is fitted and fixed to the roller 110. Here, the outer diameter enlarging portion 130 may have various thicknesses and the outer diameter enlarging portion 130 having a suitable thickness may be provided on the roller 110 according to the inner diameter of the steel plate coil 2. [

A plurality of outer diameter enlarging portions 130 are provided, and a plurality of outer diameter enlarging portions 130 are disposed apart from each other along the circumference of the roller 110.

The outer diameter enlarging portion 130 is provided on each support plate 111 and may have a length (cylindrical length) equal to or similar to that of the roller 110 corresponding to the longitudinal direction of the roller 110, The width of the support plate 111 may be equal to or smaller than the width of the support plate 111. That is, the outer diameter enlarging portion 130 does not have to be in contact with the entire surface of the inner circumferential surface of the steel coil 2, so that it can be separated from the inner circumferential surface of the steel coil 2 (see FIG. 3) .

As described above, the feeding roller portion 100a of the present invention includes the roller 110, the pressing portion 120, and the outer diameter enlarging portion 130 so that the feeding roller portion 100a is moved along the inner diameter of the steel plate coil 2, . Particularly, since the supply roller portion 100a is provided with the outer diameter enlarging portion 130, even the steel plate coil 2 having an inner diameter larger than the outer diameter of the roller 110 maximally expanded by using the pressing portion 120 can be stably supported can do. Accordingly, the feeding roller portion 100a can stably support the steel plate coil 2 regardless of the inner diameter of the steel plate coil 2, so that the steel plate can be supplied to the slitter 20 with a constant tension, It is possible to prevent the phenomenon of crying.

The engagement hole 131a may be formed as a hole having a uniform inner peripheral surface so that the screw 141 simply passes through when the screw 141 is installed on the piston 122. Alternatively, 131 may be threaded on the inner circumferential surface. That is, the coupling hole 131a of the base plate 131 is a hole in which the screw 141 is located. At this time, the engaging hole 131a is made smaller than the bolt 142 so that the base plate 131 is not detached from the screw 141.

The friction plate 132 is provided on the base plate 131 and is in close contact with the steel plate coil 2. The friction plate 132 may be made of a second material (to be described later), and the friction plate 132 is provided with a coupling hole 131a A through hole 132A through which a bolt 142 described later is inserted may be formed. Here, the through hole 132a may be formed to be larger than the hole bolt 142, which is formed so that the bolt 142 does not protrude from the friction plate 132, and may be a through hole.

In addition, the first material and the second material may be made of different materials, and the first material is made of a material having a higher rigidity than the second material, and the second material is made of a material having a higher coefficient of friction than the first material Lt; / RTI >

That is, for example, the base plate 131 may be made of any one or combination of stainless steel, steel, and alloys, and the friction plate 132 may be made of any one of urethane, polyurethane, rubber, . The friction plate 132 and the base plate 131 are integrally formed so that the friction plate 132 is coupled with the adhesive on the base plate 131 so that the friction plate 132 and the base plate 131 can be coupled to the support plate 111 by the engagement member 140 , And can be applied and fixed.

In addition, it is possible to prevent the outer diameter enlarging portion 130 from slipping on the inner side of the steel plate coil 2 by the high frictional coefficient of the surface abutting the steel plate coil 2, thereby preventing the feed roller portion 100a from being idle .

The outer diameter enlarging unit 130 may be formed of a base plate and a friction plate made of the same material. In this case, the base plate and the friction plate may be formed of a single integrated plate. At this time, the outer diameter enlarging unit 130 may be made of a wood material, but not limited thereto, and may be made of various materials such as urethane.

The engaging member 140 may include a screw 141 and a bolt 142 to prevent the outer diameter enlarging portion 130 from being detached.

When the piston 122 is moved in a direction perpendicular to the supporting plate 111 (as shown in FIG. 7) The piston 122 may be provided at a right angle with respect to the piston 122. At this time, the screw 141 may be elastically supported by a spring 141a on the inside of the piston 122 so as to be protruded or inhaled from the support plate 111. Specifically, a spring 141a is provided on the inside of the piston 122 so that the screw 141 is elastically supported to protrude through the support plate 111, so that the screw 141 protrudes from the outer diameter enlarging portion 130, The bolt 142 can be fastened on the part 130 (see Figs. 3, 4 and 6).

The engaging member 140 is inserted into the outer diameter enlarging portion 130 so that the engaging member 140 does not directly come into contact with the steel plate coil 2 The outer circumferential surface of the portion 130 abuts on the inner circumferential surface of the steel coil 2 so that the area of contact with the inner surface of the steel coil 2 is reduced so as to increase frictional force so that the steel coil 2 does not rotate .

When the outer diameter enlarging portion 130 is separated from the supporting plate 111, the screw 141 can be pushed to the inside of the supporting plate 111 with the outer diameter enlarging portion 130 removed from the supporting plate 111, A screw thread is formed on the inside of the support plate 111 so that the screw is screwed and screwed so that the screw can be prevented from being projected at random.

At this time, when the screw 141 is protruded from the supporting plate 111, a screw is formed at one end of the screw 141 and the other end is formed of a non-uniform pattern. 141a, the other end portion of the non-woven pattern is pressed and protruded, so that the time for screwing can be shortened.

A hole (not shown) through which the bolt 142 is inserted is formed in the support plate 111 so as to prevent the bolt 142 from being lost so that the bolt 142 ) May be fastened and stored.

As shown in FIGS. 3 and 9, the feeding roller portion 100a of the present invention may further include a sleeve 150. FIG. The sleeve 150 may be formed in a cylindrical shape so as to surround the upper surfaces of the plurality of outer diameter enlarging portions 130. The sleeve 150 may have various thicknesses and may be made of an elastic material The outer circumferential surface thereof abuts against the outer diameter enlarging portion 130 and is brought into close contact with the inner circumferential surface of the outer circumferential surface steel coil 2, .

Although the screw 141 of the coupling member 140 is installed in the piston 122 in the present embodiment, the screw may be separated from the piston 122 and fastened to the support plate 111 to be.

In other words, in the first embodiment, one end of the screw 141 is resiliently supported by the piston 122, but as shown in Fig. 10, in the supply roller portion 100b of the second embodiment, And the screw 1411 are simply provided between the support plate 111 and the outer diameter enlarging portion 130.

This is because a screw thread is screwed into the coupling hole 131a of the base plate 131 and another screw 1411 is inserted through the coupling hole 131a from one side to the other side, 142 are fastened together.

Here, the roller 110 and the pressing portion 110 provided in the supplying roller portion 100b of the second embodiment are the same as or similar to the supplying roller portion 100a of the first embodiment, and therefore duplicate explanations are omitted.
