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

1 is a view showing a tensile test stress strain curve of a conventional thermoplastic resin, and FIG. 2 is a view showing types of stress strain curves according to the properties of the resin.

As the core for the brim, a thermoplastic resin that can be molded into a plate-shaped synthetic resin material is used. Conventional thermoplastic resins (HDPE, LDPE, PP, PVC, PS, etc.) show similar properties according to tension, and the stress strain curve of FIG. 1 is a graph showing these properties.

When a certain stress is increased for a synthetic resin sheet or rod, the strain and elongation are increased in a certain manner within the elastic range. When the elastic deformation range is exceeded, the yield point is reached at some point, and when the yield point is exceeded, it has plastic deformation properties before reaching the breaking point. The present invention intends to apply the point that, when elongated with a tension greater than or equal to the yield point, elasticity is removed and plastic properties are obtained, and thus a shape memory aspect is shown.

According to the material of the resin, the pattern of stress deformation is different, and according to the material properties, the same aspects as A, B, C, D, and E of FIG. 2 are shown. A material such as polymer GEL exhibits the same characteristics as A, but is flexible and brittle. PS, acrylic resin, etc., show the same characteristics as B, but are hard and brittle. ABS, Teflon, PP, HDPE, etc. have the same characteristics as C, but they are flexible and strong. Materials such as R-PVC, AS, and FRP show the same properties as D and can be evaluated as hard and strong, and materials such as POM, PA, PC, and HIPS show the same properties as E, which is hard and tough. means

In order to arbitrarily deform the brim shim by elongating beyond the yield point to remove elasticity, and to prevent the deformed state from returning, use a flexible and strong resin such as C. In particular, it is preferable to adopt HDPE or a mixture thereof. . After the plate-shaped shim is molded with such a resin, it has plastic deformation properties when pulled, and the properties can be slightly changed according to the pulling displacement.

3 is a view showing the production process sequence of the brim shim according to the present invention. Referring to Figure 3, the above-described HDPE mixed resin is extruded to form a square plate-shaped resin plate (S10), cooled to room temperature (S20), and cut to an appropriate size.

After the resin plate is mounted in a property changing device to be described later, heated to an appropriate temperature (S30), it is transferred in the property changing device, and both sides of the resin plate are pulled and expanded (S40).

The resin plate heated to a high temperature loses elasticity as both sides are pulled above the yield point. However, if it is pulled too much, it reaches the breaking point and is torn or damaged, so it is necessary to determine an appropriate range. appear.

After that, the cooled resin plate (S50) is collected in the physical property changing device, cut and press-cut to the shape of a brim core if necessary, and inserted into the hat to be used.

4 is a view showing an apparatus for changing the physical properties of a brim core according to the present invention. Referring to FIG. 4 , the main body 10 is formed in a long shape of several meters, and the transfer device 20 is disposed in the longitudinal direction of the main body 10 . The transfer device 20 functions to move the resin plate 1 used as the brim core along the longitudinal direction of the body 10 at a constant speed from a starting point on one side to an end point on the other side.

The transfer device 20 includes transfer wheels such as a linear transfer wheel 21 and an extended transfer wheel 25, and the transfer line 23 is wound around the transfer wheel, and the transfer line 23 is rotated according to the rotation of the transfer wheel. will move to one side. The transfer wheel may use a chainring, a gear, a roller, and the like, and the transfer line 23 may be applied by selecting various chains, belts, ropes, and the like. The transfer wheels are arranged in combination on the main body 10 by a pair, and the transfer line 23 also forms a pair of opposing two-line lines.

A fixing device 30 is coupled to the transfer line 23 and moves together with the movement of the transfer line 23, which is formed side by side at the opposite corresponding positions of the transfer line 23 on both sides, and the fixing devices on both sides The resin plate (1) between (30) is coupled and fixed.

When the upper transfer line 23 wound up according to the rotation of the transfer wheel moves from one side to the other side of the main body 10, the fixing device 30 positioned above it and the resin plate 1 fixed therebetween will also move together.

At this time, near the starting point, the heating device 40 is disposed on the upper side, and the resin plate 1 passing to the lower part is heated. The resin plate 1 becomes flexible as the temperature rises according to the heating of the heating device 40, and changes into a state in which deformation is easy.

The transferred resin plate 1 exits the heating device 40, passes the linear feed wheel 21a, and is disposed wider than the width between the pair of linear feed wheels 21a. The section of the extended feed wheel 25a will pass through If the distance of the linear feed wheel 21a is constant, the distance of the extended feed wheel 25a is gradually increased, and the pair of opposite feed lines 23 guide the path so that the distance is gradually increased.

Accordingly, the distance between the fixing devices 30 fixed to the transfer line 23 is also widened, and the resin plate 1 automatically coupled thereto is pulled on both sides. The distance between the extended feed wheels 25a and 25 will be selected according to the thickness and size of the resin plate 1, and should be selected as a point to have an elongation between the yield point and the breaking point of the resin plate 1 .

5 is a view showing the device for changing the physical properties of the brim core according to the present invention from another direction. Referring to FIG. 5 , the resin plate 1 initially fixed to the fixing device 30 of the transfer device 20 is heated and heated by the heating device 40 while passing through the linear heating section.

Then, as the resin plate 1 is transferred to the expansion section, the transfer line 23 of the transfer device 20 is opened, and the resin plate 1 is pulled to both sides. At this time, it is preferable that the interval between the transfer lines 23 is widened by about 5 times the initial width. After the above process is completed, the resin plate 1 is cooled to room temperature in an open state, separated from the fixing device 30, and additional work is performed as necessary.

6 is a view showing a state in which the brim shim according to the present invention is disposed in the physical property changing device. Referring to FIG. 6 , the brim is seated on the transfer line 23 through the fixing device 30 .
