The present invention relates to a vinyl coating device of the waterproofing rod, and more specifically, to make a strong adhesion by pressing the vinyl paper and the sack which is coated on the inside of the sack and when the weaving machine is stopped from the coating adhesive portion of the sack and Vininyl paper. The heating rollers are spaced apart to prevent damage to the bed and the plastic sheet.

In general, the sack is one of the packaging containers for transporting and storing agricultural products, marine products and various industrial raw materials, but is used throughout the industry, but the conventional sack is not waterproof, so the contents are vulnerable to moisture or fine powder. Since it flows between the tissues of the fabric constituting the sack, there is a drawback that is subject to a lot of restrictions on the contents to be stored. In recent years, a waterproof stool is proposed by coating a plastic sheet on the inside of the stool by improving the defects of the conventional sack as described above. have.

On the other hand, as a method of coating the plastic sheet on the inside of the stem, conventionally, the outer diameter is the same size as the inside diameter of the stem, and the mandling which is sealed by adding water to the inside is put into the inside of the plastic sheet coated with the heat-sealing resin, and the vinyl sheet is coated. It spreads by the ring and heats the mandling by ultrasonic heating the water contained in the mandling, so that the heat-sealed resin applied to the vinyl paper melts and adheres to the inside of the rod, and at the same time bonds the vinyl paper and the rod by the ironing effect of the mandling. Put the tube-shaped plastic paper inside of the stool and the stem and blow the air into the plastic sheet to expand the plastic sheet. There was bonding.

 However, the bonding of the plastic paper to the sack using the mandling has a variety of specifications of the sack, so that a number of mandlings with a number of standards, which requires a lot of equipment and equipment costs, even if the sack of the same standard Depending on the weaving type and the weaving conditions, such as weaving, the diameter varies or changes slightly irregularly.In the part where the diameter of the hem is wider, the mandling is often stuck in the part where the hem and the vinyl paper are not bonded and the diameter is narrow. The product has high defects and the work is interrupted from time to time, resulting in poor productivity, and putting air into the plastic paper to coat the plastic paper with the vinyl paper and the bed close by the pressure of the air. Not only the adhesive strength of the plastic sheet is weak, but the plastic sheet is torn If incorrectly bruise drill because air leaks vinyl Sack paper and the adhesive could not be a high percentage of defective defects.

The present invention has been made to improve the above-mentioned drawbacks as described above to use a heating roller to press the plastic paper and the sack tightly to adhere firmly, and if necessary, the heating roller can be lifted and lowered apart from the stool. The purpose of the present invention is to propose a vinyl coating device for a waterproofing rod to obtain a high quality waterproofing rod by preventing the formation of the glue and the plastic sheet by the heat of the heating roller or the unbonded portion.

In order to achieve the above object, the present invention is a pair of upper and lower airtight rollers (9, 901), respectively, which is positioned between a pair of air compressor nozzles of the compressor in the needle and the plastic paper to form a needle and The air is supplied through the vinyl, and the hole drilled by the air supply nozzle passes through the lower airtight roller 901 so that the remaining air is trapped between the upper and lower airtight rollers (9) and 901 so that the inner plastic paper ( The vinyl paper 701 is unfolded within the sack 601 by expanding the 701 so that the sack 601 is brought into close contact with the sack 601 or the expanding machine is in contact with the sack 601.
