Problems solved by technology

[0004] The purpose of this invention is to propose a spraying device baffle for forming metallized film screen strips, which can effectively solve the problem of small-sized metallized films due to the dense distribution of screen strips and uneven oil vapor of each nozzle. The problem of fuzzy blackening can improve the capacitive performance of the metallized film

Embodiment Construction

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0016] The present invention is arranged at the outlet of the spraying device for spraying shielding oil vapor on the surface of the film, see figure 1 , 2 shown. The inner side of the baffle 1 is provided with an air storage cavity 11 for storing shielding oil vapor. The baffle 1 is provided with nozzles 2 distributed along the length direction for spraying shielding oil on the surface of the film. Hole 21, the top of the air storage chamber 11 is provided with a sub-air storage chamber 22 with enlarged cross-section at the inlet end of the fuel injection hole 21 of each nozzle 2 for buffering the pressure, and the depth of the sub-air storage chamber 22 is 0.1-0.15 cm. The sub-air storage chamber 22 may be a cylinder, an elliptical cylinder or a cone, or may be a stepped shape with a diameter gradually decr...

Abstract

The invention belongs to the technical field of metalized film processing and discloses a spraying device baffle plate for forming a metalized film screen zone. A gas storage chamber for storing screening oil vapor is arranged inside the baffle plate which is provided with nozzles which are distributed along the length direction and used for spraying the screening oil to the surface of the film, oil spray holes communicated with the gas storage chamber are formed in the middle of the nozzles, and a branch gas storage chamber with an enlarged section for buffering the pressure is formed at the inlet end of the oil spray hole of each nozzle on the top of the gas storage chamber, wherein the depth of the branch gas storage chamber is 0.1-0.15cm. By forming the branch gas storage chambers, pressure buffering regions are arranged between the inner cavity of the spray device and the nozzles, so that the oil pressures of the nozzles are tend to be consistent, and therefore, the problem that the edge of the metalized film screen zone is blurry and black is eliminated and the electric performance of the metalized film is improved.

Description

technical field [0001] The invention belongs to the technical field of metallized film processing, and in particular relates to a baffle plate of a spraying device for forming a small-sized metallized film screen strip. Background technique [0002] Metallized film is to evaporate metal aluminum and zinc on the surface of BOPP film or BOPET film to form a metal coating. According to the width of the metal coating according to the user's needs, a blank margin with a certain width is reserved on one side of the metal coating, which is called screen belt. The margin area must be clear and uncoated, the connection between the blank margin area and the metal coating must be clear, and there must be no blurred buffer zone. In production, oil coating and shielding are usually used, that is, before the film is evaporated, a layer of oil film is sprayed on the corresponding blank margin area in advance to prevent metal adhesion during evaporation. This kind of spraying equipment for...
