Method and device for manufacturing sticking film with three-dimensional pattern

Abstract

The invention discloses a method and a device for manufacturing a sticking film with a three-dimensional pattern. The method comprises the following steps of: placing a PVC (polyvinyl chloride) film material printed with transparent gypsophila patterns on a die of which the surface has a raised shape; firmly adsorbing the film material on the surface of the die by means of vacuumizing; and baking the film material. The device comprises the die of which the surface has the raised shape, a vacuumizing apparatus, a heating apparatus and a pushing apparatus, wherein the external contour line of the raised shape of the die is corresponding to that of a printed pattern at a specified position on the film material, the die is provided with at least one air hole penetrating through the upper and lower surfaces of the die, the air hole is communicated with the vacuumizing apparatus, the vacuumizing apparatus is used for extracting air between the film material and the die after the film material is placed on the die, and thus, the film material can be firmly absorbed on the surface of the die, the heating apparatus is used for baking the film material, and the pushing apparatus is used for exerting pressure on the film material on the die.

Description

technical field [0001] The invention relates to the technical field of film sticking, in particular to a film sticking manufacturing method and device presenting three-dimensional patterns. Background technique [0002] The mobile phone shell film of the prior art is generally a film of a plane pattern, and its manufacturing method is to print a plane pattern on the film material, and then add a self-adhesive sticker on the back of the film to complete the manufacturing process of the film. The film pattern of the plane pattern There is no three-dimensional effect and lack of realistic and dynamic effects, so the flat pattern sticking films of the prior art need to be improved urgently. Contents of the invention [0003] Features and advantages of the invention are set forth in part in the description which follows, or may be obvious from the description, or may be learned by practice of the invention. [0004] In order to solve the problems of the prior art, the pres...
