In more detail, it automatically feeds the handle to the detention part and at the same time supplies the wire to the banding process through the through hole of the handle, and cuts both ends of the wire by a predetermined length, and both ends of the cut wire by the cylinder The present invention relates to a wire banding machine which presses a moving block and a jig to be operated to bend over 1st, 2nd and 3rd stages and to automatically discharge the finished carrying handle after bending.

Products distributed in a liquid state, such as general paints, oils, pharmaceuticals, and foods, are packaged and transported in a container of iron cans or plastic cans. It moves to the target place using the handle wire provided so that both ends were rotatable in the upper part. The handle wire has a shape of an arc or a square as a whole, the handle is banded on both sides so that the handle is inserted in the ordinary wood or synthetic wood so as not to be separated within a certain section, and both ends of the processed wire are bent inward to hook Form. This is done by cutting the wire wound by the worker to a certain length, putting the handle made of synthetic resin or wood by another worker, taking the primary banding of the arc or the corner, and then cutting both ends of the hook form from one side. Since it was dependent on the manual work performed and completed, the workability and productivity were remarkably degraded, the working environment was also poor, and the machining work was performed in the form of the manual work as described above. Due to this, the reliability of the product is lowered, causing excessive spending of labor costs, which is not profitable, and there is a problem to be improved, such as the inability to supply parts smoothly due to a surge in quantity.

In particular, the hook type of the above-mentioned hook type is limited to the iron can of the manufacturing company, which is inevitably used, which is difficult to bind to the upper part of the container because of the hook type, and the handle wire may be deformed during the binding process. Highly likely, the insertion hole formed in the upper portion of the container was limited to the iron can formed through.

When using this in a resin can, that is, a container in which a flange is formed at the top and an insertion hole is formed at the outer surface of the flange, the binding portions at both ends of the wire must be deformed. The problem still remains, which, combined with workability and productivity and profitability, has emerged as an urgent problem to be improved.
