Description

[Detailed Description of the Invention] The present invention relates to a guide device for a flocking needle that protrudes and retracts from the top of an outer cylinder in a flocking sewing machine. The top end of the outer cylinder of the needle feed mechanism in conventional flocked sewing machines is open,
In the case of hair transplantation, the head of a vinyl chloride doll, which is the object to be transplanted, is placed on an outer cylinder, and the head is automatically transferred stitch by stitch as the sewing machine operates. By the way, when hair is transplanted to the collar area, the sides of the ears, and the bangs of the doll's head, the doll's head 6 is bent approximately 90 degrees to the left or right as shown in FIG. When the needle, which has strong elasticity, is inserted into the doll's head, it is pulled by the bent head and is bent extremely in the same direction. At the moment when this bent needle hooks the yarn and is drawn into the outer cylinder, the restoring action of the needle causes the inside of the annular yarn formed by the previous needle operation on the back of the grafted body, that is, the doll's head. It has the disadvantage that it cannot pass through, and the needle jaws cut the circular thread. The present invention was made with the aim of eliminating this drawback, and an arc-shaped opening 3 is provided at the top end of the outer cylinder 1 through which the flocking needle 2 can move in and out. Hole edges 4 and 5 on both sides of tube 1
is formed on the guide of the hair transplant needle 2. As illustrated in FIG. 5, the conventional outer cylinder has an open upper end, so that during hair transplantation, the needles are bent by the above-mentioned hair transplantation operation of the doll head 6, and this bending is caused by the retraction of the needles and the elasticity of the needles. As shown in Figure 6, the needle quickly returns to a straight line, but since the degree of curvature at the time of protrusion is large, the needle oscillates greatly when recessed into the outer cylinder, which causes the annular part formed in the previous operation to It has the disadvantage that it deforms the thread, cannot pass through the annular part, and cuts the thread with the jaws of the needle. If the yarn (corresponding to the hair in this case) is cut on the back side of the doll's head, the hair will fall out as shown in Figure 7, so there is no point in transplanting the hair, and in fact no hair will be transplanted.

According to the present invention, as described above, an arcuate hole 3 having a required width through which the needle moves in and out is formed at the upper end of the outer cylinder, and the hole edges 4 and 5 on both sides of this opening are used as guides for the needle 2 to move in and out. Since the needle moves along this guide and emerges and retracts, the curvature of the needle is suppressed by the guide, so there is no wobbling of the hand when it is retracted, and the action of returning to a straight line is achieved. is fast, therefore, it is formed one stitch in advance and passes through without any trouble without deforming the ring of the chain annular part.

Therefore, according to the present invention, the hair transplanting operation is carried out smoothly, the breakage of the needles is reduced, and the production of defective products in which the doll's hair falls out is prevented, and the efficiency of the hair transplantation work is further improved.
