Description

Processing equipment to process engraved patterns on leather goods

The present invention relates to a non-flammable processing device, and more specifically, through the improvement of the structure of the non-flammable processing device for processing the engraved pattern on the surface of the product to be able to mass-produce products of constant quality regardless of the operator's skill The present invention relates to a non-flammable processing apparatus for processing engraved patterns on the surface of a product to realize precise non-fabrication processing and to enable precise product processing by forming a stable connecting structure.

Polyurethane leather is a material widely used in diaries, bags, clothes, shoes, etc. The manufacturing process is largely divided into wet and dry.

Wet process for producing polyurethane artificial leather is composed of a polyurethane solution coating, coagulation, moisture removal, drying process, each process will be described as follows.

In the polyurethane solution coating step, a polyurethane solution of 700 g or more per square meter is applied to a base fabric such as a nonwoven fabric. The solvent of the polyurethane solution is pure D.M.F. (Dimethyl formamid).

In the coagulation process, the polyurethane solution is coated on the fabric and then passed through a water bath containing water to solidify the polyurethane solution. At this time, the organic solvent D.M.F. in the drug is combined with water, and the remaining solids are solidified.

The solidification process is a part which shows a great difference from the dry manufacturing process of polyurethane artificial leather. After the application of the dry silver polyurethane solution on the release paper, it passes directly through the dryer, so that all solvents evaporate and only the polyurethane solids remain. After the film is thinned to about 20 to 30% of the thickness of the initially applied polyurethane solution, the wet is almost 100% of the thickness of the polyurethane solution applied by the coagulation process in water remains.

The water removal process is a state in which the D.M.F. combined with the solidified polyurethane solids and water is mixed in the solidified polyurethane film layer and passes through two compression rollers to remove water from the polyurethane film layer. The removal of water causes D.M.F., which is bound to water, to escape from the first applied polyurethane solution, creating an innumerable cell, which creates cushions, breathability, and a leathery feel.

The drying is to smooth the moisture-removed product with a dryer.

In addition, a dry process for producing a polyurethane artificial leather is composed of a polyurethane solution coating, primary drying, adhesive coating, secondary drying, bonding, aging and separation process, each process is as follows.

In the polyurethane solution coating process, the polyurethane solution is coated on a release paper with a thickness of about 0.15 to 0.2 mm (about 100 to 150 g of polyurethane solution per 1 m 2).

The primary drying step is to evaporate the polyurethane solution applied to the release paper with hot air so that the polyurethane solution is in a film state of 100% solids.

In the adhesive applying process, the adhesive is applied to the dried film to bond the film and the base fabric.

The secondary drying step is a step of drying by applying hot air to the adhesive applied to the film. At this time, in order to become a suitable adhesive force for bonding the base fabric, all of the solvent of the adhesive is dried and removed, and the adhesive force is excellent when the adhesive is cured by approximately 50%. This is a process in which drying and chemical reactions are performed at the same time as the first drying, and the adhesive is excellent in adhesive strength by controlling the reaction rate by the mixing ratio of the solvent and the adhesive and the temperature of the dryer.

In the bonding process, the base fabric is attached to the adhesive having the proper adhesive strength through the secondary drying, and the film is adhered by pressing with a pressing roll.

Since the aging process is only 50% of the adhesive is cured through the secondary drying, the adhesive is completely cured by storing at least 80 hours in a aging room at 80 ° C.

The separation process is a process of separating the release paper from the product after the aging process and the separated release paper is reused. Since the surface of the release paper is embossed, the embossed form of the release paper is transferred to a polyurethane film to produce a three-dimensional polyurethane artificial leather.

As described above, the polyurethane artificial leather is manufactured in a dry and wet manner, and only the wet synthetic polyurethane leather can be heat burned.

The impurity processing refers to stamping a trademark, a figure, a character, etc. on the polyurethane artificial leather in an intaglio form by pressing a mold heated on the polyurethane artificial leather.

In this case, the non-flammable processing may be a product made of paper, wood, and PVC material used for business cards, promotional materials, etc., as well as leather products such as wallets and diaries.

On the other hand, the wet polyurethane artificial leather is a form in which there are a myriad of empty spaces (cell) in the film, such as a sponge, when pressed to the mold heated to about 180 ℃ to the cell inside the film is pressed and the mold and The contacted film surface is burned slightly. Then, when the mold is peeled off, the portion pressed into the mold is not recovered and remains pressed.

Heat burnishing as described above compresses the cells by heat and pressure to fill the cells, so that only the portion in contact with the mold is locally deformed without deforming the other side of the film.

In other words, the physical force is applied to reduce the volume of the film, and the area pressed by the mold is made in the form of intaglio, and the surface is burned with heat to make the color or gloss different from other parts.

However, there is a problem in the conventional non-deformation processing by the manual workability and product productivity is lowered, as well as the difference in workability according to the processing skill of the operator to reduce the quality of the product.
