Description

A safety-equipped hot-melting device

The present invention relates to a hot-melt device equipped with a safety device, and more specifically, the gap between the driving stop and the upper and lower rollers is automatically performed by the operator's emergency switch pressing operation in response to an emergency situation or the safety cover rising operation by the operator. It relates to a hot-melt device equipped with a safety device to promote the safety of workers.

In various fields, there are many processes of applying and attaching adhesive to the product during production, and when the worker manually applies, the thickness of the adhesive does not become constant and the work efficiency decreases because the adhesive must be applied individually along the adhesive application site. There was.

In recent years, hot melts, which are thermoplastic resins, have been used as adhesives that have little harm to humans compared to ordinary bonds. Such a hot melt is a solid adhesive that does not contain an organic solvent and is in a solid or semi-solid state at room temperature, melted by heating, coated, and solidified while being cooled and adhered.

A hot-melt device equipped with a heating means is used in various fields so that the adhesive in the form of a hot-melt thermoplastic resin can be maintained in a liquid state. And in the Republic of Korea Patent Office Registration No. 10-1322508 "Album inlay manufacturing apparatus using a hot-melt film" is a device for laminating the hot-melt film to the support after applying heat to the support, without directly applying heat to the hot-melt film.

In addition, a hot-melt device is formed in a table shape, and an operator is inserted between the lower roller and the upper roller to insert the object to be adhered, resulting in an accident in which the operator gets his or her hand when the object is inserted. In addition, the lower roller and upper roller are fixed to the body frame, so it is difficult to disassemble and cannot be quickly taken out when the operator's hand is caught. A bolt that adjusts the distance between the lower roller and the upper roller is located on the upper part of the heating device and burns. There was a problem that it could lead to a secondary accident because of the high risk of wearing it.
