Problems solved by technology

[0002] In the process of activating the coating film, the method of spraying with a spray gun is often used. In this method, sometimes the operator uses multiple spray guns improperly, and the pressure of the sprayed activator is too high, thus causing damage to the coating mold.
Moreover, during the spraying process of the spray gun, due to the different distances, it needs to spray back and forth, which will cause the problem of uneven spraying of the activator

Embodiment Construction

[0022] A three-dimensional curved surface coating transfer method, comprising the following steps: (1) transfer film: pre-print the desired pattern with a water-soluble film, provided by the supplier of the coating film; (2) film release: put the coating film Cut it into the required specifications of the workpiece and place it on the water surface, drain the air between the water and the film to make it completely flat on the water surface; (3) Activation: Spray the activator on the film through the activation equipment to activate the pattern on the film. Ink state; (4) Transfer printing: use water pressure to transfer the pattern activated into the ink state on the printed workpiece; (5) Washing: rinse the residual film after transfer with a washing line; (6) Baking Drying: Dry the printed workpiece in an oven; (7) Spray topcoat; spray the dried workpiece with a transparent protective layer [varnish] to protect the surface, and dry it again.

[0023] Such as Figure 1-10 A...

Abstract

The invention discloses a three-dimensional curved surface coating transfer method, which includes the following steps: (1) transfer film: pre-print the required pattern with a water-soluble film, provided by the coating film supplier; (2) film release: Cut the coating film into the required specifications of the workpiece and place it on the water surface, drain the air between the water and the film to make it completely flat on the water surface; (3) Activation: Spray the activator on the film through the activation equipment to make the film (4) Transfer printing: use water pressure to transfer the pattern activated into ink state to the printed workpiece; (5) Washing: rinse the residual film after transfer with a washing line (6) Drying (7) Spray topcoat; The present invention adopts the mode of mobile spraying; Guarantees the distance between the atomizing nozzle and the coating mold all the time, and the activator can be completely coated on the film by one movement , to avoid the problem of uneven spraying, but also to improve work efficiency.

Description

technical field [0001] The invention belongs to the technical field of coating transfer printing, and in particular relates to a three-dimensional curved surface coating transfer printing method. Background technique [0002] In the process of activating the coating film, the method of spraying with a spray gun is often used. In this method, sometimes the operator uses multiple spray guns improperly, and the pressure of the sprayed activator is too high, thereby causing damage to the coating mold. Moreover, during the spraying process of the spray gun, due to the different distances, it needs to spray back and forth, which will cause the problem of uneven spraying of the activator. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a three-dimensional curved surface coating and transfer printing method that uniformly sprays and reduces the number of repetitions during spraying. [0004] In order to ach...
