Spray head of sand-blasting machine with sand-blasting openings arranged in array staggered mode

Abstract

The invention discloses a spray head of a sand-blasting machine with sand-blasting openings arranged in an array staggered mode. The spray head comprises a spray head body, wherein a sand-blasting table-board is arranged at the front end of the spray head body; a plurality of rows of sand-blasting openings, which are arranged in the form of an array, are formed in the sand-blasting table-board; the upper-row sand-blasting openings and the low-row sand-blasting openings in the sand-blasting table-board are arranged up and down in a staggered mode; distances among the sand-blasting openings are the same; the rear ends of the sand-blasting openings are connected with a sand-blasting guide tube; and the rear end of the sand-blasting guide tube is connected on a spraying discharge header tube by virtue of a connecting tube. In this way, the spray head can carry out sand-blasting treatment in a relatively uniform and fine mode; after being sprayed out by the sand-blasting discharge header pipe, the sand-blasting material is dispersed into each sand-blasting opening for being sprayed out, so that the sand-blasting is more uniform, and therefore, the sand-blasting thickness of the material surface is prevented from being uneven.

Description

technical field [0001] The invention relates to the field of sandblasting machines, in particular to a spray head of a sandblasting machine with arrays and staggered arrays of sandblasting ports. Background technique [0002] After sandblasting, the surface of the workpiece will obtain a certain roughness, improve the fatigue resistance of the workpiece, increase the adhesion between it and the coating, prolong the durability of the coating film, and also facilitate the flow of the coating. Peaceful decoration, remove impurities, variegated colors and oxide layers on the surface, roughen the surface of the medium at the same time, eliminate the residual stress of the workpiece and improve the surface hardness of the substrate. However, the traditional sandblasting machine sprays out materials from a single outlet. It is inevitable that due to technical influences, the thickness of the material sprayed on the surface of the material will vary, resulting in unevenness and affe...

Problems solved by technology

However, the traditional sandblasting machine sprays out materials from a single outlet, which will inevitably be affected by technology, which will make the thickness of the material sprayed on the surface of the material vary, resulting in unevenness and affecting the pass rate.
