Roller conveyor automatic sandblasting machine is a commonly used sandblasting equipment for surface sandblasting of workpieces. The working principle is as follows:
Workpiece handling: First, the workpieces to be processed are fed into the blasting chamber via a conveyor. The conveyor can be used as rollers, belts or chains to smoothly transport the workpiece to the blasting area.
Sandblasting chamber: The blasting chamber is the main area of the sandblasting process. It is usually an enclosed chamber with adjustable inlet and outlet doors to control the inflow and exit of the workpiece.
Abrasive blasting system: The blasting chamber is equipped with a blasting system, including compressed air and abrasives** system. Compressed air passes through the nozzle to create a high-velocity airflow that draws the abrasive from the abrasive bin below the blast chamber and sprays it onto the surface of the workpiece.
Sandblasting effect: The high-speed airflow carries the abrasive to the surface of the workpiece to achieve the sandblasting effect. The choice of abrasives can be determined according to the workpiece material and processing requirements, and the common abrasives are quartz sand, glass beads, steel shots, etc.
Complete sandblasting: After the workpiece is processed by the sandblasting system in the sandblasting room for a certain period of time, the abrasive, dirt, oxide layer, etc. are impacted and thrown down. After the blasting is complete, the workpiece exits the blasting chamber through the discharge door.
Discharging and collection: The processed workpiece is sent out of the blasting chamber by the conveyor and enters the next process. At the same time, dirt and abrasives in the blasting chamber are collected and treated through the discharge system for recycling.
In general, the roller conveyor automatic sandblasting machine feeds the workpiece into the sandblasting chamber through the conveying device, and uses the sandblasting system to generate high-speed airflow and abrasives to impact and throw the surface of the workpiece to achieve the sandblasting effect. The dirt and abrasives in the blasting chamber are treated by a collection system, while the blasted workpieces continue to be conveyed. This kind of sandblasting machine has the characteristics of automatic operation, efficient processing and recycling, and is widely used in the field of surface treatment in industrial production.
