Embodiment Construction
[0014] The present invention will be described in further detail below by means of specific embodiments: the local sandblasting technique of no ink covering, comprises the following steps:
[0015] ①. Punch the product into shape.
[0016] ②, product polishing treatment: put the material tray for the product to be polished and place it in front of the material loader, take a product with each hand and put it on the jig of the automatic line at the same time, and perform friction cutting operation on the surface of the product through the polishing cloth wheel , prepare the corrugated board before unloading, put the corrugated board containing the product in front of the position, remove the polished product from the jig of the automatic line with both hands at the same time, and discharge it into the card slot of the corrugated board one by one. The polishing surface treatment process uses cloth wheels of various materials and polishing abrasives to perform friction cutting on...

Abstract
The invention discloses an ink-shielding-free local sand blasting technology. The technology is characterized by comprising the following steps: 1, product punching and molding; 2, product polishing treatment: performing friction-cutting operation on the surface of the product by using a polishing rag wheel; 3, anodic oxidation lightening: placing the product on a positive electrode, and applying a voltage and current to facilitate formation of an oxidization film on the surface of the product; 4, sand blasting: performing sand blasting operation on the product through a spray gun, performing cutting treatment on the surface of the product by using sand grains in order to form fine convex-concave pits on the surface of the product, and smoothening the convex-concave pits by using an alkali etching process and a chemical polishing process; 5, anodic oxidation dyeing. By adopting the local sand blasting technology, ink shielding printing is not required, a polished surface and a sand-blasted surface can coexist, and the problem that the product with a deformed surface cannot be printed is solved.
Description
technical field [0001] The invention relates to the technical field of surface treatment, in particular to the partial sandblasting technology without ink masking. Background technique [0002] In the traditional process, the same product needs to have a bright surface and a sandblasted surface at the same time. It is necessary to use printing ink to cover and print the bright surface, then sandblast, and then remove the ink and then oxidize and dye. However, the special-shaped surface of some products cannot be printed. , so it is impossible to have a bright surface and a sandblasted surface at the same time. The special-shaped surface includes a raised surface or an uneven surface, etc. Therefore, for products with special-shaped surfaces, it is necessary to have a bright surface and a sandblasted surface at the same time A difficult problem in traditional craftsmanship. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present inventio...
