Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded three-dimensional configuration of the leather pattern forming apparatus according to the invention, Figure 2 is a combined three-dimensional configuration of Figure 1, Figure 3 is a cross-sectional plan view of Figure 2, Figure 4 is a front face of the pattern forming part of the forming roller This is the schematic view from.

Here, "A" of FIG. 1 is an enlarged view of the excerpt, and [A] to [C] of FIG. 4 is a configuration diagram showing various embodiments of the pattern forming part of the forming roller.

As shown in Figure 1 to 4, the leather pattern forming apparatus using the radiant heat of the built-in heat generating means according to the present invention,

It consists largely of the heat ray mounting body 10, the support 20, the heating wire 30, the forming roller 40 and the frame 50.

Looking at each configuration,

Heat wire assembly (10)

A body 11 having a predetermined length, and

The receiving portion 12 of the plurality of recessed in the longitudinal direction while being arranged radially on the outer peripheral surface of the body (11)

It is made, including.

The term 'constant length' means a length corresponding to the width of the leather, the molding position, and the size of the pattern, which are major products for forming the pattern.

The support 20 is

To be inserted through the center of the body 11 of the heat ray mounting body 10,

Round pipe 21, and

Inlet 22 formed in the pipe 21

It is made, including.

Here, the inlet part 22 is formed of a central hole 221 inside the pipe 21 and an opening hole 222 penetrating outside the pipe 21 and connected to the center hole 221. Inlets 22 are formed at both ends of the pipe 21.

The inlet 22 serves as an inlet space for the external power supply line 1.

And the pipe 21 of the support 20 is preferably greater in length than the roller body 41 of the forming roller 40 to be described later.

As a result, both ends of the support body 20 arranged inside the roller body 41 of the forming roller 40 are exposed to the outside of the roller body 41, and the clamping member 52 to be described later is mounted on both exposed ends.

On the other hand, the pipe 21 of the support 20 is a thermal expansion deformation occurs by the radiant heat of the heating wire 30, this thermal expansion deformation can damage the heat wire mounting body 10,

In order to prevent this, the pipe 21 has a slit 23 in the longitudinal direction to induce deformation inward during thermal expansion deformation of the pipe 21.

On the other hand, the pipe 21 of the support 20 is provided with two supports 60 which respectively support both ends of the hot wire mounting body 10 and having a power supply line 1 distributor 61.

The support 60 has the distribution part 61 formed at a position corresponding to each receiving part 12 of the hot wire mounting body 10.

Accordingly, an end portion of the heating wire 30 exiting from one of the receiving parts 12 to the receiving part 12 is a power supply line 1 drawn into the distribution part 61 at a position corresponding to the one receiving part 12. ).

Heating line 30

Is connected to the power supply line (1) drawn through the inlet 22 of the support 20, and arranged in each receiving portion 12 of the heat ray mounting body 10,

In one receiving portion 12 to the other receiving portion 12 to form a structure that is continuously wound to lead to another receiving portion 12, wherein the heating end 30 and the end of the heating wire assembly 30 (10) It is arranged at both end sides, respectively.

In addition, the start end and the end of the heating wire 30 arranged at both ends of the heating wire mounting body 10 are connected to the power supply line 1, respectively.

As a result, it is connected to the power supply line 1 drawn into the inlet 22 formed at each end of the pipe 21 of the support 20.

The heating wire 30 may be selected from various heating wires such as a PVC-based heating wire, an alloy heating wire, a silicon heating wire, a non-magnetic heating wire, a planar heating element, a carbon heating wire, and a non-magnetic silicon (magnetic-free + silicon type).

In addition, the heating wire 30 is preferably in the form of a coil in order to maximize the heating effect.

Forming roller 40

The hot wire mounting body 10 is to be spaced apart to be rotatably mounted on the support 20,

Cylindrical roller body 41 having a hollow 411, and

A pattern forming part 42 provided on an outer circumferential surface of the roller body 41 to mold a pattern on leather through the radiant heat of the heating wire 30.

It is made, including.

Here, the hollow 411 of the roller body 41 is larger than the diameter of the pipe 21 of the support 20 to form a space between the two components (roller body and the pipe).

This is to eliminate the interference between the roller body 41 and the pipe 21 through the spaced space portion to enable the free rotation operation of the roller body 41.

And referring to Figure 4, the pattern molding portion 42

In a first embodiment, as shown in Fig. 4A, a plurality of connection holes 421 formed at both ends of the roller body 41 and wires 422 wound around the connection holes 421 are formed. .

As a result, the leather, which is a large molding product, is shaped to conform to the shape of the wire 422 of the pattern forming part 42 which is brought into contact by the front and rear rolling operation.

In a second embodiment, as shown in [b] of FIG. 4, an embossed pattern (for example, a star shape) is formed on the outer circumferential surface of the roller body 41,

In a third embodiment, as shown in [C] of FIG. 4, a pattern (eg, a star) of an intaglio is formed on the outer circumferential surface of the roller body 41.

In addition, as described in the first embodiment described above, the pattern molding part 42 is rolled back and forth on the leather, which is a large molding product, to form the respective patterns.

The present invention is not limited to each embodiment described above, and various modifications and changes may be possible.

On the other hand, in the hollow 411 at both ends of the roller body 41, bearing members 80 are mounted by bolts, respectively, and the pipes 21 of the support body 20 pass through the bearing members 80. do.

As a result, the support member 20 is non-rotated through the bearing member 80, and the forming roller 40 is capable of rolling back and forth.

On the other hand, a lubricant is used for the bearing member 80 and the support 20. Since grease is commonly used because of poor heat resistance, it is preferable to use a graphite lubricant for high temperature.

Frame 50 is

To be connected to both ends of the support 20,

‘ㄷ’ -shaped connecting frame (51),

Two clamping members 52 provided at each end of the connecting frame 51, and

Cross frame 53 is connected to the connection frame 51 stop portion

It is made, including.

Wherein the clamping member 52 is composed of two pressing pieces 521 of mutually opposite form, each pressing piece 521 is mutually using a bolt and a nut in the state fitted to the pipe 21 of the support 20 It is mounted with a clamping structure according to the fastening in the opposite direction.

And the cross frame 53 of the frame 50 is preferably provided with a grip portion 70 of the form that is easy to hold by hand,

In addition, it is preferable that a temperature control unit 90 is provided for setting / maintaining a pattern forming appropriate temperature.

The temperature control unit 90 connects or cuts off the power applied to the heating line 30 according to a temperature value sensed through a temperature sensor (not shown) or the like, so that the surface of the forming roller 40 (ie, the pattern forming unit) (42) It keeps the temperature at 150-500 degreeC.

Leather pattern forming apparatus of the present invention looked into the above configuration

After contacting the leather with the forming roller 40 heated to an appropriate temperature through the radiant heat of the built-in heating wire 30,
