KR970010057A - Simultaneous Coating on Two Large Diameter Tubes - Google Patents

Abstract

The present invention provides a simultaneous coating apparatus for two large-diameter tubular body to improve the coating efficiency and to enable coating of uniform thickness by depositing two large tubular tubes at the same time and then rotating and depositing the entire tube in the coating liquid. And a pair of support rails installed on the floor to support the tube to be coated for this purpose; A swing arm installed at the end of the support rail by a cylinder operation to transfer a tube placed on the upper portion of the support rail to the front of the support rail; A pipe conveying device for holding the pipe placed on the support rail two by two to move the clamped pipe by self-driving means in an axial direction along a transfer rail installed in the air and to raise or lower the pipe; ; An adhesive container for depositing the tube as an enclosure placed across the transfer rail to the front bottom of the support rail and containing an adhesive applied by pretreatment prior to coating the vertical liquid on the tube; A resin liquid storage container installed in front of the adhesive container and accommodating a pipe body descending from an upper portion thereof to coat the resin liquid; A cooling device installed in front of the resin liquid reservoir and spraying cooling water from both sides of the lowered pipe; A protective solvent accommodating passage installed in front of the cooling apparatus and accommodating a protective solvent applied to protect the resin coating layer; And a discharge rail installed to extend outward from the inside of the transfer rail to discharge the coated pipe body in front of the protective solvent container.
