Next, the emboss roller 40 is configured to form an emboss on the surface of the leather that has passed through the leather spreading device 30.

The emboss roller 40 is configured to circulate the heated oil to the inside so that the embossing can be well formed by supplying the heat source to the surface 48 including the embossment 48a.

In detail, the emboss roller 40 will be described in detail.

3, a first oil supply line 41 for supplying heated oil to the emboss roller 40 is formed at one side (left side in FIG. 3) of the emboss roller 40, The second oil supply line 42 for moving the heated oil supplied through the supply line 41 to the heating line 43 adjacent to the surface 48 on which the embossment 48a is formed is formed on the emboss roller 40, Is formed in the central portion in the axial direction in which the first and second base plates 21 and 22 extend.

On both sides of the heating line 43 are formed first and second discharge chambers 44 and 45 for discharging the oil that has been deprived of the heat source after coming into contact with the surface 48. The first and second discharge chambers 44 and 45, and a second oil discharge line 47 formed in the second discharge chamber 45 for discharging the oil to the outside.

The thickness of the surface 48 of the emboss roller 40 is preferably 55 to 65 mm.

Next, the first roller (R1) is formed on the lower side between the leather transferring unit (20) and the leather spreading device (30) so as to be able to move while supporting the lower part of the leather to be transferred.

Next, the second roller R2 is formed so as to be able to transport the leather in cooperation with the first roller R1.

However, the second roller R2 is positioned by adjusting the vertical position with respect to the first roller R1 so that the leather to be conveyed can be moved in a horizontal state in a horizontal direction, but the leather can be more contacted with the emboss roller 40 The embossing roller 40 and the embossing roller 40 are arranged to be in close contact with each other.

Next, the driving roller 50 is configured to move the leather together with the emboss roller 40.

Particularly, in the driving means 50 described above, a pair of drive roller shafts 51, which are formed by forging the inner side with the shock absorbing grooves 51a formed therein, as shown in Fig. 4, are connected by the connecting member 52 A plurality of flanges 53 are formed in the axial direction of the driving roller shaft 51 and the connecting member 52 and the plurality of shock absorbing holes 53a are formed in the outer peripheral surface of the driving roller shaft 51 and the connecting member 52, And a surface portion 54 formed by bending an iron plate at the outer side of the metal plate 53.

Here, the thickness of the surface portion 54 of the driving roller 50 is preferably 55 to 65 mm.

The function and effect of the ultra-high-pressure embossing machine according to the present invention having the above-described structure will be described below.

First of all, the leather to be supplied is roughly divided into the leather spreading device 30 by the first felt 21 of the leather transferring part 20 coupled to the housing 10, In the direction in which the guide member is formed.

At this time, the first contacting portion 31 of the leather spreading device 30 disposed on the upper side of the leather transferring portion 20 comes in contact with the first felt 21, and the wrinkles and the like of the leather passing therethrough are spread So that the leather can be unfolded first.

Meanwhile, the leather immediately after passing through the leather transfer part 20 acts to spread the leather once again while abutting against the second contact part 32 of the leather spreading device 30, so that the second leather can be stretched.

That is, before and after the embossing process, the work of unfolding the leather is performed so as to improve the merchantability of the leather.

Particularly, the leather spreading device 30 is rotatably coupled to the housing 10 by a rotation shaft 33. Even if a thick leather is passed through the leather spreading device 30, the leather spreading device bracket 34 is lifted upward, The present invention can be applied to various thicknesses of leather, and continuous work can be performed without stopping the machine, and the leather can be processed to a certain thickness during the process of increasing the leather.

Here, the position of the second contact portion 32 of the leather spreading device 30 is determined by the action of the first and second rollers R1 and R2 in the section where the leather moves flat in the horizontal direction So that it can be efficiently performed.

In the meantime, the embossed leather is moved on the surface by the emboss roller 40. In particular, embossing is maintained for a long time by the heat source applied to the emboss roller 40, thereby enhancing the merchantability of the leather, Further, since the second roller R2 is disposed at a position where the contact area between the leather and the emboss roller 40 can be increased, the effect of forming the emboss on the surface of the leather can be obtained.

The embossing roller 40 is rotated by the driving roller 50 disposed at the lower side of the embossing roller 40 so that the embossing can be formed on the surface of the leather by the operation of the embossing roller 40 and the driving roller 50.

In the meantime, the emboss roller 40 according to the present invention supplies oil at an intermediate position in the axial direction of the emboss roller 40 when the heated oil is injected into the emboss roller 40 so that the heat source transmitted across the entire surface 48 is almost constant Thereby enhancing the efficiency of the embossing process.

That is, in the present invention, the heated oil supplied to the first oil supply line 41 extending in the horizontal direction passes through the second oil supply line 42 formed at the center of the axial direction of the emboss roller 40, The oil is supplied to the heating line 43 for supplying the heat to the surface 48 on which the oil 48a is formed.

Since the heated oil moved to the center moves in the direction in which the first discharge chamber 44 on the left side and the second discharge chamber 45 on the right side are formed, the travel distance of the oil having the heat source is very short compared with the conventional one, The heat source can be delivered to the surface 48 evenly within a short period of time to improve the efficiency of the embossing process.

In order to circulate the oil, the emboss roller 40 of the present invention includes a first oil discharge line 46 at the center of the outermost surface 48, a first oil discharge line 46 at the middle portion, Since the line 41 has a triple structure, it is possible to prevent bending and breakage of the emboss roller 40 even when applied to a large apparatus using an ultra-high pressure.

The driving roller 50 in the present invention has a plurality of flanges 53 and a surface portion formed by bending an iron plate on the outside of a pair of driving roller shafts 51 having an inner shock- 54).

Therefore, even when applied to a large apparatus using an ultra-high pressure, impact absorption is performed by the shock absorbing groove 51a of the drive roller shaft 51 and the shock absorbing hole 53a formed in the flange 53, Since the plurality of flanges 53 are supported in the axial direction, deformation due to warpage and breakage are prevented from occurring, so that it is possible to obtain an effect that can be used for large equipment that generates an ultra-high pressure.

Particularly, in the present invention, the emboss roller 40 having embossed patterns 48a formed at the upper end of the housing 10 is stored in the holder 11, and then the hoist H is used to quickly replace the emboss roller 40 The workability can be improved.
