Attached-type winding vacuum aluminizing machine and manufacturing method of reflective warning tape

Abstract

The invention relates to an attached-type winding vacuum aluminizing machine which can be used for producing a product which is distinct in a boundary line between an aluminized area and a non-aluminized area and a manufacturing method of a reflective warning tape, wherein the reflecting tape is manufactured by using the attached-type winding vacuum aluminizing machine, a high-temperature resistant soft fabric barrier in the attached-type winding vacuum aluminizing machine is positioned between a substrate and an evaporating boat and closely attached to the substrate surface without a gap under the action of a tensile force, so that the produced product is distinct in a boundary line between the aluminized area and the non-aluminized area. The attached-type winding vacuum aluminizing machine has the advantages that the definition of the boundary outline of the reflective warning tape manufactured by using the attached-type winding vacuum aluminizing machine is remarkably improved, so that the product quality is improved; the width of an aluminized strip can be changed at will by using a high-temperature fabric, so that the specification and size of the reflective warning tape can be conveniently changed regardless of an A area or a B area, therefore the production cost is effectively reduced and the diversification of the product in terms of specification, size and the like is achieved; and the weight of a mold material is reduced and the loading and unloading time is shortened.

Problems solved by technology

Its disadvantages: First, due to the winding vacuum aluminum plating machine, it evaporates aluminum wire at high temperature in the vacuum chamber, so that the aluminum vapor adheres to the high-speed running substrate to form a uniform aluminum layer. However, it is necessary to realize the negative and positive plating For aluminum, the non-aluminized area must be isolated from the aluminum vapor, but the substrate is continuously operating at high speed in the vacuum chamber, and the temperature of the aluminum vapor is very high, so a metal barrier is used to block between the substrate and the evaporation boat. It is required to make the grid block close to the base material, but due to metal is a hard material, processing technology and processing cost, etc., the grid and the base material cannot be closely bonded and there is a gap, so the negative and positive aluminum plating is inevitable. The demarcation line is unclear and fuzzy, which directly affects the quality of the product; second, the processing technology of the arc-shaped metal grid with a diameter of Φ600 is extremely harsh, and it is very difficult to succeed, and the processing cost is extremely high, resulting in high manufacturing costs
