In general, an automatic sealer is an embroidery device for manufacturing a decorative fabric by forming a decorative pattern on a fabric in a pattern or pattern preset by a computer or the like. A plurality of utility models have already been applied by the applicant for the automatic sealer. It is.

The decorative fabric is a three-dimensional design by sealing the beautiful shape and pattern using a cord yarn or sequins on the fabric, the cord yarn is a kind of thread used to form a constant pattern on the fabric in the embroidery machine,絲) Because it is made by twisting into several strands, its thickness is much thicker than yarn, and it is possible to express various colors in one cord yarn, and it is possible to manufacture cord yarn of various forms according to the type of yarn used and the twisting method. .

However, in order to seal the cord yarn or sequin together on the fabric, a sealing device for sealing the cord yarn and a sealing device for sealing the sequins should be provided, respectively, and the size of the sealing device becomes large, resulting in high equipment costs. There was this troublesome problem.

In addition, a timing gear was used to operate the sealing device. A conventionally used timing gear simply rotates in conjunction with another timing gear by a timing belt to perform a role of simply transmitting rotational force. Since there is no space for winding the cord yarn at the bottom, the cord yarn is wound at the top of the timing gear to seal the cord yarn and the sequins with a single needle. At this time, the separation distance for separating the sequins through the sequin pressing portion is shortened. There was a problem that could not be properly separated.

The present invention has been made to solve the above problems, when the timing gear is rotated by the timing belt, the cord yarn is wound around the support formed integrally inside the timing gear, and the sealing operation is performed separately or separately with the sequins inserted into the through hole. In particular, in the state in which the swivel is inserted into the support is formed integrally in the center of the front portion, the cord is wound on the swivel and the sequins inserted into the through hole or separately sealing operation is carried out, and after the sealing operation is completed, when pulling the cord yarn, It is an object of the present invention to provide a timing gear for an automatic sealer in which the rotating table is reversely rotated to easily rewind the cord yarn.
