Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment, and in particular relates to a transfer equipment. Background Art

[0002] At present, consumers have higher and higher requirements on the appearance of industrial products.

Currently, the main processes for mass printing and coloring of the surfaces of structural parts include screen printing, spraying, and pad printing.

[0003] Among them, screen printing can only print 2D flat surfaces and smaller curved surfaces, but cannot print large curved surfaces and special-shaped surfaces; spraying can achieve coloring of various special-shaped surfaces, but cannot color precise patterns and fixed areas, and can only be done blindly, and cannot replicate precise patterns and spraying of fixed areas in large quantities, and the spraying process is costly and not environmentally friendly; the traditional pad printing process can print borders, lines, text and local precise patterns on various curved and special-shaped surfaces, but cannot print on large surfaces, because the middle position of the pad printing rubber head cannot be vented when taking ink, which will result in the inability to take ink in the middle of the rubber head or incomplete ink taking, and the pressure in the middle position of the rubber head is the highest during printing, which will cause the ink in the middle to diffuse to the surrounding area, the ink in the middle is thin, and the ink thickness is uneven, which ultimately leads to very poor color consistency on the workpiece surface.

[0048] The elastic transfer film assembly 50 is disposed on the screen printing platform 42 .

[0049] The support device 10 can be used to install the product installation device 20 and the screen printing device 30 on the transfer device, wherein the product installation device 20 is arranged on the support device 10, and the screen printing device 30 is arranged on one side of the support device 10. The product installation device 20 can be used to install the product to be printed, and the screen printing device 30 can print the pattern to be printed on a certain flat object or a small curved surface object. The elastic transfer film assembly 50 is elastic and can be used for transfer. After the screen printing device 30 prints the pattern on the elastic transfer film assembly 50, the elastic transfer film assembly 50 can transfer the pattern to the product. Because the elastic transfer film assembly 50 itself is elastic, when transferring to a special-shaped product, the elastic transfer film assembly 50 can fully fit the special-shaped product to transfer the pattern to the special-shaped product.
