One-way automatic sandblasting machine

Abstract

The invention relates to an automatic unidirectional sand blasting machine. The automatic unidirectional sand blasting machine comprises a shell, sand blasting heads are arrayed in a sand blasting chamber formed in the shell, the shell is provided with a push-in port allowing pushing of pipe fittings into the sand blasting chamber, the shell is provided with a dustproof portion at the push-in port, and the dustproof portion covers the push-in port. A water curtain circulation device comprises a water spraying pipeline and a circulation water tank, the water spraying pipeline and the pipe fittings are parallel are arranged on two sides of the sand blasting chamber respectively, and a plurality of water spraying ports are formed sequentially along the length direction. The circulation water tank is positioned at the bottom of the sand blasting chamber, one end of the circulation water tank serves as a circulation end to extend outside the shell, and the height of the bottom of the circulation water tank is gradually decreased along with approaching of the circulation end. A filter screen for filtering quartz sand is arranged at the joint of the circulation water tank and the wall of the shell, and a secondary grinding device for reutilization of blast sand for grinding is arranged in the sand blasting chamber. The automatic unidirectional sand blasting machine is high in quartz machining efficiency, and work environment pollution caused by flying dust is avoided.

Description

technical field [0001] The invention relates to a sandblasting machine, in particular to a one-way automatic sandblasting machine. Background technique [0002] Due to the impact and cutting effect of abrasives on the surface of the workpiece, the surface of the workpiece can be obtained with a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved, thus improving the fatigue resistance of the workpiece and increasing its The adhesion between the coating and the coating prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating. It removes impurities, variegated colors and oxide layers on the surface, and at the same time roughens the surface of the medium to eliminate the residual stress of the workpiece. and improve the surface hardness of the substrate.

Problems solved by technology

[0003] The traditional sandblasting machine includes a shell, in which there is a sandblasting chamber, and a sandblasting head is arranged in the sandblasting chamber. When the pipe is pushed in from one side of the sandblasting chamber, the sandblasting head sprays quartz sand on the pipe, and the quartz The sand collides with the outer periphery of the pipe fittings to remove the dirt and rust stains on the outer periphery of the pipe fittings. The above-mentioned sandblasting machine has the following problems: ①After the quartz sand hits the pipe fittings, it will generate dust, which will pollute the working environment around the sandblasting machine. On the one hand, the dust It is easy to cause explosion, and on the other hand, it affects the health of the staff; ②The quartz sand is vertically impacted on the outer circumference of the pipe fittings, and most of the quartz sand is rebounded by the pipe fittings after the impact, resulting in low processing efficiency of the quartz sand and serious waste of quartz sand; ③It is difficult to collect quartz sand after use, and it is often discarded after sorting out, which increases the production cost; ④After the pipe fitting enters the sandblasting room, it will not rotate automatically, and it can only be blasted at the same time by setting the sandblasting head in multiple directions, resulting in the same mechanism duplication and complexity of the internal structure
