Description

An apparatus for automatically processing end points of brassiere wire}

The present invention relates to an end point treatment apparatus of braze wires, in which the powder coating process is completed, and more particularly, to supply and preheat, powder coating, drying and cooling discharge of holders to which the wires are fixed according to the end point treatment of braze wires. The invention relates to a brazier wire end point automatic processing device for the entire process to take place automatically.

The end point treatment of the brazed wire refers to the entire surface of the brazed wire metal wire bent to fit the size of the brazier cup first through a separate coating line to prevent rust. The end is coated, but its shape is sharp, so if it is not processed smoothly, it is impossible to insert into the sewing groove of the bra cup, and when the bra is worn, the end sticks out of the bra sewing seam and damages the body or damages the body. Cause problems. Therefore, in order to increase the safety of the braze wire essentially means that both ends of the primary coating is treated with a predetermined material through a separate process.

Conventionally, the end point treatment of the braze wire has been relied on by hand. That is, in the prior art, the brazier wire, which has been finished with powder coating, was first applied to a coating material (epoxy) by hand by a worker and dried and treated in a separate drying line. Therefore, the above-described conventional working method is very primitive, requires excessive manpower, the processing speed of the end point of the brazier wire is very slow, and there is a lot of work to be moved by each work process. Due to various problems such as deterioration of the productability due to the end point treatment is not constant, the productivity of the brazier wire, which requires a large amount of production, is inevitably deteriorated, resulting in a loss of competitiveness.

On the other hand, epoxy (liquid), which is a coating material used for the end point treatment of conventional brazier wires, is often cracked or broken due to external impact or contact with sewing needles, even though it is dried. There is a problem that adversely affects the human body due to the discharge of the ingredients.

The present invention is to solve the above-mentioned conventional problems, the object of the present invention is to make each process according to the end point treatment of the brazed wire first powder coating process to be made by an automatic system rather than manual operation, high efficiency and low cost In addition to strengthening the competitive edge, the end point processing is always constant and quick to provide an automatic processing device for the end point of the braze wire, which can improve the quality of the braze wire and increase the productivity.
