Sealing process of louver hollow leaf

Abstract

The invention relates to a method for sealing hollow blade of louver, wherein it comprises the hollow plastic blades with two open ends. And the method comprises that: (1), producing mould with sealing hole relative to the section of blade, and the mould has sealing device; (2), starting and setting sealing device; (3), inserting one end of blade into sealing hole, the end will be extruded to close the open, and the sealing device will adhere the open to seal it. The invention has low cost and high efficiency.

Description

(1) Technical field [0001] The invention relates to a sealing process for hollow louver blades, in particular to a process for quickly sealing hollow louver blades made of plastic. (2) Background technology [0002] Blinds are a sun-shading structure used for light adjustment on windows, and are widely used because they can prevent others from peeping in addition to the sun-shading function. The curtain blades of traditional blinds are generally molded integrally with plastic, and thin metal plates are pressed into metal sheets with arc-shaped cross-sections. Although the metal sheet is lighter, it is easy to be damaged due to the low bending strength of the curved cross-section, and the shading degree is not strong, and the heat insulation and sound insulation effects are not good. The solid plastic structure consumes more materials, is heavier, and has higher manufacturing costs. Since the blades are solid, the blades become a good conductor of heat and noise. In order t...

Problems solved by technology

Although the metal sheet is lighter, it is easy to be damaged due to the low bending strength of the curved cross-section, and the shading degree is not strong, and the heat insulation and sound insulation effects are not good

The solid plastic structure consumes more materials, is heavier, and has higher manufacturing costs. Because the blades are solid, the blades become a good conductor of heat and noise.

In order to solve the above problems, the applicant invented a hollow blade of a louver made of plastic, which basically overcomes the shortcomings of the existing blades. However, due to the openings at both ends of the hollow blade, a new problem of quickly sealing the blade has emerged.
