Problems solved by technology

During the whole process, there will be the following problems: due to the high temperature of the evaporator (up to about 1550 ° C), the baffle is located directly above the evaporator, so that the baffle will be deformed by heat and arch downward; and in order to ensure evaporation The material will not overflow from the evaporator too much, and the distance between the baffle and the upper rail of the evaporator is very close (less than 1cm); in this way, during the shielding process of the baffle, a large amount of aluminum evaporation material will adhere to the bottom of the baffle, causing When the baffle needs to be removed before the start of thin-film aluminum plating, it is stuck and cannot be removed

Embodiment Construction

[0010] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0011] like figure 1 As shown, the anti-deformation structure of the evaporator baffle plate in the vacuum aluminum plating equipment of the present invention includes a body 300 and at least two rows of milling grooves 301. The milling grooves 301 are on the body 300, and each row of milling grooves 301 is parallel to each other. The shape of the milling grooves 301 is Oval.

[0012] The structure of the main body is a structure similar to a plate stiffener. On the premise of not destroying the circulating waterway, the present invention mills grooves on the main body, which reduces the material used for the baffle and enhances the water cooling effect (from about 200°C to about 120°C), which reduces the weight of the body, reduces the longitudinal expansion, and reduces the deformation caused by heat and ...

Abstract

The invention discloses an evaporator baffle deformation-preventing structure in vacuum aluminizing equipment. The evaporator baffle deformation-preventing structure comprises a body and at least two rows of milled slots, each row of milled slots are in parallel on the body, and the milled slots are elliptic. The weight and the longitudinal expansion rate are reduced and the deformation caused by heat and heavy weight is reduced, so that the total thermal deformation of the evaporator baffle deformation-preventing structure is reduced, and the service life of a baffle is prolonged.

Description

technical field [0001] The invention relates to a vacuum aluminum coating equipment, in particular to an anti-deformation structure of an evaporator baffle in the vacuum aluminum coating equipment. Background technique [0002] Aluminized film products have strong barrier properties, which can block sunlight and prevent ultraviolet rays. The common aluminized film can be used for solar explosion-proof film: mainly used for the lamination of automobile glass; electronic shielding film: mainly used for electromagnetic shielding of electronic products. [0003] Vacuum aluminum plating equipment is a device that evenly coats a layer of aluminum on a paper or plastic film. In order to ensure the purity and uniformity of the coating, the equipment adopts the technical method of vacuum aluminum plating to work. Its working principle is: the coil is evaporated by the evaporation process. In the vacuum chamber, the evaporation material (aluminum) is evaporated with the aid of a su...
