Foreign material contamination prevention device for powder coating

The present invention relates to a foreign material contamination prevention device for powder coating, and more particularly, in a powder coating system comprising a pretreatment step, a drying step, a coating step, a heat treatment step, etc. By installing the foreign matter collecting plate on the circulating hanger device, it is possible to block and collect pollutants such as foreign matter falling to the subject, thereby minimizing the defective rate caused by it, stabilizing the product quality and improving the working environment. It relates to a foreign material contamination prevention device of a powder coating drying furnace.

In general, the reason of applying powder coating on the surface of the finished metal product is slightly different depending on the material property and usage of the product, but it usually maintains corrosion resistance, acid resistance, alkali resistance, moisture resistance, weather resistance, etc. There are important objectives to maintain long service life of the product, and other objectives to improve the merchandise that may vary depending on the quality of the outer surface expressed by the thickness or color of the coating film.

The facilities of each company that specializes in such powder coating, although there are slight differences depending on factors such as the size, quantity, use of the object, etc., has established a system as shown in FIG.

In detail, the pretreatment process and the drying furnace are arranged in the workshop of a certain area, and the automatic or manual coating process, the heat treatment and the drying process, which are selected according to the size of the subject, are spaced at a fixed distance, In each process, a hanger device that transports and circulates a fixed object is arranged to circulate along a predetermined track.

In such a hanger device, a guide rail is conventionally fixed to the upper side so as to be circulated according to each process, and a plurality of hangers are provided at equal intervals between the roller, the support, and the fixed rail. The dog is rotatable.

Such a hanger device has a relatively small amount of pollutants in the early stages of the construction of the facility, so the drop rate of the hanger is low. However, as a result, the wastes generated from the rotating rollers circulating along the guide rails are passed. Various contaminants such as oil and dust will drop onto the moving object while being fixed to the hanger.

The contaminants such as waste oil are solidified or discolored as the lubricants injected regularly or irregularly over time so that the operation of the rotary roller is smoothed and pushed out of the friction surface of the rotary roller. It falls down by vibration and self-weight, which causes fatal defects in the product.

Particularly, due to the characteristics of the painting work, powders scattered in the painting process are accumulated on the guide rails, and then fall as the rotary roller moves and fall to the subject, which is another source of contamination. As a result of coating the pollutant on the object as it is, the surface of the product becomes irregular or damages the aesthetics.

The defective rate of products caused by these facilities is higher than expected, so it is not profitable, and in order to solve this problem, it is necessary to completely remove the painted coating on the surface of the product and rework. As a result, problems such as deterioration of workability and productivity and inequality of working environment existed.

The present invention has been researched and created to fundamentally solve all the problems of the prior art as described above, the main object of providing the same is to install the foreign matter collecting device in the hanger device that circulates along a certain orbit while fixing the subject to the process It is intended to block and collect pollutants such as foreign substances falling onto the object by installing them.

Another object of the present invention is to minimize the defect rate of the product due to the removal of contaminants such as foreign matter by the above-mentioned foreign matter collection device, thereby to stabilize the product quality.

Still another object of the present invention is to improve the working environment of each process because the pollutant is removed by the foreign matter collection device.
