Toothbrush's slim fur and method of therefore

The present invention relates to a method for manufacturing a slim hair and a slim hair, and in particular, by brushing the edge portion of the upper edge located in the lower side of the slim hair which is planted in a folded state folded in the head of the toothbrush, brushing, It prevents gums from being damaged during the process and prevents the slender hair from bending in the outward direction of the head to extend its life.

In general, the toothbrush is to use a toothbrush with a slim hair is formed in the shape of the needle tip in the form of a needle to prevent damage to the gum during the brushing process.

These slim hairs were prepared in the form of needles by treating the end of the yarn form made of nylon or polybutylene terephthalate (P.B.T) with alkaline solution.

In the process of manufacturing the end of the slim hair needle, there was a problem that a lot of defects occur because it is difficult to adjust the total length and taper length accurately.

In addition, the gum is damaged by the end of the slim hair or there was another problem that the gap between the teeth.

In addition, even when not used for a long time due to the weakness of the slim hair, the needle part of the slim hair had another problem of shortening its lifespan as it was deformed to the outer side of the toothbrush head.

An object of the present invention is to provide a slim hair manufacturing method and a slim hair which can prevent the gums from being damaged during brushing and at the same time prevent the slim hair from bending in the outward direction of the head to extend its life.

The present invention provides a method for manufacturing a slim wool planted in the head of the toothbrush, the slim hair yarn extrusion step (S100) is the raw material is extruded in the form of yarn going through the extruder; A hardening step (S200) in which the extruded yarn is naturally cured; A cutting step (S300) in which the cured yarn is cut by a cutter and formed in a unit hair; A sharpening step (S400) in which one side of the cut unit hair is sharpened by an alkaline solution and manufactured as a unit slim hair; A cutting surface polishing step (S500) in which the other side of the unit slim wool having one side sharpened is transferred to a grinder by a feeder and the cutting surface is polished flat; An edge polishing step (S600) in which the edge of the polished unit slim wool is polished again; The slim edge storage unit is characterized by consisting of a slim hair storage step (S700) is drawn out of the polishing machine and stored in the storage box.

In addition, the edge of the edge polishing step (S500) is to provide a method of manufacturing a slim wool, characterized in that the rounded or tapered shape.

On the other hand, the present invention is a slim hair planted in the head of the toothbrush, the slim hair is formed on one side sharply and the other side is gathered a plurality of unit slim hair formed with a polished portion is planted in the folded state 1/3 is folded in the head The grinding portion is horizontally cut so that the polished edge is formed to be inclined from the round shape or from the other side to the other side.

And the horizontal grinding portion to provide a slim hair characterized in that the groove is formed in the form of a mountain.

The present invention has the effect of preventing the gums from being damaged during the brushing process by allowing the edge portion of the upper edge located in the folded state folded in the folded state of the head of the toothbrush to be polished round or tapered. Can be obtained.

In addition, it is possible to further prevent the slim hair from bending in the outward direction of the head to extend the life.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

Slim hair 200 according to the present invention, as shown in Figures 3 and 4, to be planted to have a predetermined interval gathered in a folded state a plurality of unit slim hair 210 in the head 110 of the toothbrush pole 100 The unit slim cap 210 is formed at the top end sharpened portion is formed and the polished portion 230 is formed on the top of a certain length of about the entire height or 1/3 of the length from the sharpened portion And, the polishing unit 230 is configured to be integrally formed to be horizontally cut and polished edge in a round shape or inclined from one side to the other side.

In addition, as shown on the right side of FIG. 4, the horizontally cut surface of the polishing unit 230 is provided with a groove 240 having a mountain shape to prevent gums from being damaged in the process of brushing and at the same time slim hair ( By supporting the lower portion of the 200) it can be prevented from being deformed in the open state.

The method of manufacturing a slim wool having such a configuration is as shown in Figs. 1 and 2, first, in the yarn extrusion step (S100), the synthetic resin, which is polyester-based, is extruded into a yarn shape that is melted in the extruder 400, and then extruded yarn. Natural curing in the process of being transported (hardening step (S200)).

Next, the hardened yarn in the cutting step (S300) is cut to a predetermined length by the cutter 410, one unit hair 210 is formed, the cut unit hair 210 is one side sharpened by an alkaline solution One unit slim wool 220 is manufactured (preparation step (S400)).

Next, the cut unit slim hair 220 is transferred to the grinder 430 by the feeder 420, and the cut surface is polished flat (cut surface polishing step S500).

Next, the edge of the polished unit slim hat 220 is polished through the edge polishing step (S600), and the edge- polished unit slim hat 220 is drawn out of the polisher 430 and stored in the tray 440. Slim hair is manufactured through the slim hair storage step (S700) to be stored.

At this time, the edge of the unit slim wool 210 in the edge polishing step (S600) is preferably to be polished in a round or tapered form.

1 is a process chart showing a slim hair manufacturing method according to the present invention.

Figure 2 is a block diagram of the equipment used in the method for manufacturing slim hair according to the present invention.

Figure 3 is a cross-sectional view of the slim cap according to the present invention.

Figure 4 is an exemplary view showing various forms of unit slim hat according to the present invention.
