characteristic:The triangular belt is used to transport the workpiece, which will not accumulate sand. The belt speed can realize variable frequency speed regulation according to the requirements of sand blasting process; The angle of each spray gun can be adjusted freely, the gun holder can realize automatic frequency conversion and swing, and fixed-point sand blasting can be carried out, with strong flexibility and wide applicability; Advanced cyclone separation system configuration is adopted, with good dust separation effect and high sand blasting efficiency; PLC advanced electrical control system is adopted, with high degree of automation, good stability and low failure rate; The nozzle is made of special high wear-resistant ceramic material with long service life; Independent bag dust removal system, good dust extraction and ventilation effect; (also optional; pulse filter element type dust removal); The abrasive recovery adopts the combination of screw conveying and pneumatic recovery, with good recovery stability.Applicable working conditions1) Environmental conditions: the machine shall work normally under the ambient temperature of - 10 ~ + 45 ℃ and the relative humidity of no more than 85%;2) Power supply conditions: single phase AC power supply, 220V, 50Hz. See attached table-3 for the maximum power of the machine;3) Air source conditions: the gauge pressure of the compressed air connected to the machine is 0.4 ~ 0.7MPa, and the compressed air flow is not less than 1m3 / min.The user site shall meet the above conditionsSand material used:Jichuan abrasives are supplied throughout the year: brown corundum sand, glass sand, silicon carbide glass, walnut sand, resin sand, emery, alumina sand, steel sand and steel shot, plastic particles (nylon sand), ceramic beads, etc.Main purpose of automatic sand blasting machine1. Cleaning and strengthening of external surface of parts;2. Cleaning and strengthening of tools, fixtures and materials;3. Surface cleaning of parts before electroplating, oxidation and coating;4. Remove pollutants on the surface of barrels, tubes, plates, cans and utensils;5. Cleaning of tools, molds, pipes, plates and operating parts;6. Surface cleaning of glass mold, rubber mold, metal casting and extrusion;7. Repair welds;8. Surface glaze of workpiece;9. Remove the oxide scale on the workpiece surface and remove the color difference during and after processing (castings and forgings);10. Clean large turbines, engine castings or complex small parts;11. Clean parts (such as cylinder block, piston and spark plug) during engine maintenance;12. Clean the surfaces of brushes, contactors and wiring technology to improve conductivity;13. Cleaning and preservation of parchment and other works of art;14. Remove the old paint and dirt on the workpiece surface.Operating proceduresAccording to the different requirements of workpiece material and processing technology, qualified sand shall be added before processing. Set the speed of the conveyor belt, the swing frequency of the spray gun, the amount of sand, the air pressure, etc. the workers only operate the control system and load and unload the workpiece, and the sandblasting on the workpiece surface is automatically completed by the machine.Start the suction and dust removal system and start the spray gun.Place the workpiece on the conveyor belt. (for small and light workpieces, the customer needs to customize the fixture)The conveyor belt conveys the workpiece into the sandblasting chamber at a uniform speed; The spray gun is driven by the swing motor to do repeated swing sand blasting to automatically sand blast the workpiece surface.After processing, the workpiece enters the blowing room (dust cover), and the internal blowing gun blows the residual sand on the workpiece surface to remove static electricity; Automatic output, just remove the product.The machine adopts continuous sand blasting.Turn off the power switch when not in use.The machine needs more than 2 operators (one for storage and one for retrieval)
