Description

Cutting device for cylindrical fabrics {HEATING CUTTER FOR CYLINDRICAL FABRIC}

The present invention relates to a device for cutting a cylindrical fabric with a heater, and in particular, by heat-treating the cylindrical fabric with hot air and then cutting it with a hot wire, it is possible to easily post-process the cut fabric by easily preventing curling of the cut portion. The present invention relates to a cutting device for cylindrical fabric.

Cylindrical fabric is generally referred to as a circular knit (knit) called Daimaru, which is a structure formed in a cylindrical shape while forming a loop in the horizontal direction, and using both threads continuously or alternately using different kinds of threads. It is generally stretchy compared to the woven products by squeezing the nose.

Such a fabric may be used as it is in a cylindrical shape, but usually after the fabric is cut in the longitudinal direction and spread out flatly, it is post-processed.

Thus, the related art cutting device for cylindrical fabrics is configured to generate heat by applying electricity to a heating wire in a fixed state, and then transfer the fabric in the longitudinal direction to pass the heating wire.

Since the conventional cutting device cuts the cylindrical fabric as it is, the elasticity of the fabric causes curling at the cut portion, which makes post-treatment work such as setting processing of the fabric very difficult, thus cutting and post-processing the cylindrical fabric. The disadvantage is that it is difficult to proceed continuously.

The present invention was invented to solve the problems of the prior art as described above, by heat-treating the cylindrical fabric with hot air and then cutting it with a hot wire, thereby easily preventing the curling phenomenon of the cut portion to conveniently cut the fabric after It is an object of the present invention to provide a cutting device of a cylindrical fabric that can be processed.

In order to realize the above object, the present invention is a cutting device for a cylindrical fabric consisting of a fabric supported by two fabric guide members spaced apart from each other by the width of the fabric is cut by a hot wire while proceeding in the longitudinal direction, The central fabric support rod for guiding the inner center portion of the fabric in the longitudinal direction is disposed in parallel with the heating wire, and a heater for heating air is installed at the outlet side of the blower, and the hot air guide member surrounding the heater is opened at the lower side of the blower. Cylindrical fabric comprising a spaced apart in parallel to the fabric center support rod in communication with the outlet of the air is heated by the heater is heated by the heater to heat the upper central portion of the fabric through the lower portion of the hot air guide member It provides a cutting device of.

The cutting device of the cylindrical fabric according to the present invention is heated by the heater is discharged to the lower side of the hot air guide member while being heated by the heater to heat the upper center portion of the fabric in the longitudinal direction and heat-treated the fabric Since the cutting is performed in a state where the cut portion is heat-treated, the curling phenomenon of the cut portion is easily prevented, and thus there is an advantage that the cut fabric can be conveniently post-processed.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 is a view showing a cutting device of a cylindrical fabric according to the present invention, the cutting device of the present invention, as in the prior art, is provided with two fabric guide members 2 spaced apart from each other in the width of the fabric (1) Doing.

Since the fabric 1 surrounds the fabric guide member 2 and proceeds in the longitudinal direction, the fabric 1 is guided by the fabric guide member 2 and proceeds in the longitudinal direction, and the fabric 1 The upper central portion of the fabric 1 is cut along the longitudinal direction by the heating wire 3 while being supported by the fabric guide member 2 and traveling in the longitudinal direction.

In the present invention, the upper central portion of the fabric 1 is to be heat-treated with hot air before being cut by the hot wire (3).

That is, the center fabric support rod 11 for guiding the inner central portion of the fabric 1 in the longitudinal direction is disposed in parallel with the heating wire 3.

And a heater 12 for heating the air is installed on the outlet side of the blower 13, the hot air guide member 14 surrounding the heater 12 while opening to the lower side in communication with the outlet of the blower (13) It is spaced apart in parallel with the fabric center support rod (11).

Of course, the fabric center support rod 11 is installed between the two fabric guide member (2), the blower 13 and the hot air guide member 14 to the frame 4 (only a small portion is shown briefly) It is fixed.

Thus, the present invention includes a structure in which the air moving by the blower 13 is heated by the heater 12 to heat the upper central portion of the original fabric 1 through the lower portion of the hot air guide member 14.

2 and 3, the cutting device of the cylindrical fabric according to the present invention is formed so that the upper center portion is cut by the heating wire 3 and unfolded while the fabric 1 moves to the left side of FIG. do.

At this time, the air forced by the blower 13 is heated while passing through the circumferential surface of the heater 12 before the upper center portion of the fabric 1 reaches the hot wire 3, and the heated air is heated by the hot air guide member. It is discharged to the lower side under the guidance of (14).

And the hot air discharged to the lower side of the hot air guide member 14 passes through the upper central portion of the fabric 1 to heat-treat the fabric 1.

Then, even if the upper center portion of the fabric 1 heat-treated by hot air is cut by the heating wire 3, the cut portion is not dried because it is in a set state by heat.

Therefore, although not shown, it is possible to easily realize a post-treatment process such as setting the entire fabric by transferring the fabric edge portion cut by the heating wire 3 to the pin.

On the other hand, if the fabric heated by the high-temperature air discharged from the hot air guide member 14 can be more smoothly cut by the hot wire 3, as shown in FIG. The fabric blown by the air discharged from the hot air guide member 14 is cooled by the blower 15 to the outside air immediately before being cut by the hot wire 3, the blower 15 is It is provided between the outlet outer surface of the blower 13 and the heating wire 3.

Then, the central portion of the fabric deviating from the lower side of the hot air guide member 14 may be cooled by the air of the outside air discharged from the blower 15, so that the fabric cooled by the outside air is smoothly cut by the hot wire 3. will be.
