Description

Styrofoam engraving machine

The present invention relates to a styrofoam engraving machine capable of engraving styrofoam.

In general, sculptures can be made by carving styrofoam. When carving styrofoam, various tools can be used. For example, a rotating tool such as a drill tool can be used, and a heating wire can be used.

Using a heating wire can be divided into two types, for example, one can be used to cut out the outline of a sculpture, and the other can be used for a delicate sculpture.

That is, when carving styrofoam, as described above, three tools can be selected to perform carving, and the heating wire can be bent and used according to the intention of the worker.

The conventionally known technology will be described in more detail with reference to Patent Documents 1 to 3.

Patent Document 1 is a styrofoam model cutter using a nichrome wire. The patent document 1 is a technique in which a nichrome line is traversed in a horizontal direction and a styrofoam is carved while moving the nichrome line according to an X-Y left sign value. The patent document 1 is used to roughly cut the external shape of a sculpture when carving styrofoam, and there is a limit to making delicate carving.

In addition, Patent Document 2 is a hot wire engraver. Patent Literature 2 is a technique for improving the engraving work speed by allowing the heating wire to be produced in a desired shape. As described above, when sculpting styrofoam, there is no choice but to use a variety of tools, but Patent Document 2 is a single tool that uses a hot wire, and there is a limit to roughly and quickly sculpting the external shape of the sculpture to be engraved.

In addition, Patent Document 3 is a styrofoam processing apparatus. Patent Literature 3 is a configuration that includes a hot wire tool and a drill tool, which can roughly sculpt the external shape of a sculpture using a hot wire tool and can perform detailed processing using a drill tool.

However, Patent Literature 3 requires that the drill tool be avoided so that it does not interfere with the work of the hot wire tool when carving styrofoam using a hot wire tool. It is too high, and there is an inconvenience of securing a high ceiling of the factory.

In more detail, the cutting tool left and right operating means are installed in the frame so as to move in the front-rear direction, and the cutting tool vertical operating means are installed on the cutting tool left and right operating means to move the cutting tool in the vertical direction.

That is, in Patent Document 3, when the cutting tool is not in use, the cutting tool up and down operation means is operated to move it to the upper position to return to the avoided position. In this case, the height of the uppermost end of the cutting tool up and down operation means is above the frame. There is a problem in that the ceiling of the work space must be secured high because the height of the work space has to be raised by protruding.

In addition, Patent Document 3 is a configuration in which the heating wire is installed to be transverse in the left-right direction, and the styrofoam can be sculpted while moving in a vertical direction while performing relative motion with the styrofoam.

On the one hand, as a configuration to move the heating wire up and down, the motors for heating wires are installed on both left and right sides.To keep the heating wire in a horizontal state, the motor for heating wires must be accurately synchronized and controlled and operated at the same time with accurate values. In the field, there are many errors in synchronizing the two motors, and there is a risk of carving in a state where the heating wire is not level, unlike the intention of the operator.

Meanwhile, the helical directions of the second screw 435 and the third screw 436 may be opposite to each other. As a result, the third pulley 463 described above may be installed on the third screw 436, and the first and second gears 471 and 472 may be deleted.

Therefore, the styrofoam engraving machine according to the embodiment of the present invention further simplifies the configuration of the head assembly 400 and has an effect of implementing the movement direction of the rotary tool 452 and the finishing hot wire cutting unit 454 in the opposite direction. Can be implemented.

In addition, the styrofoam engraving machine according to an embodiment of the present invention may be configured to include a third plate 423 as shown in FIG. 9, and the third plate 423 may be formed of the first plate 421. Can be placed on the lower side.

One of the second and third screws 435 and 436 may be installed on the second plate 422, and the other side of the second and third screws 435 and 436 is attached to the third plate 423. Can be installed.

As a result, the second and third screws 435 and 436 are supported by both sides, so that they can be operated stably with arbitrary shaking.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. I will be able to.

Therefore, the embodiments described above should be understood as illustrative and non-limiting in all respects, and the scope of the present invention is indicated by the claims to be described later, and derived from the meaning and scope of the claims and the concept of equivalents thereof. All changes or modified forms should be construed as being included in the scope of the present invention.

The styrofoam engraving machine according to an embodiment of the present invention can be used to engrave styrofoam.
