Conveyor-type automatic sandblasting machine / Continuous batch-processing conveyor-type automatic sandblasting machine

This conveyor‑type sandblasting machine is built from high‑quality carbon steel plates of no less than 4mm thickness, shaped through laser cutting, precision bending, and full‑penetration CO₂ welding. After welding, the entire structure undergoes shot blasting and electrostatic powder coating with a film thickness exceeding 80μm, delivering outstanding corrosion resistance and impact strength to ensure long‑term stable operation even in dusty, high‑humidity workshop environments. As a pass‑through automatic sandblasting machine specifically engineered for continuous assembly‑line work, its variable‑frequency belt conveyor system provides infinitely adjustable speeds from 0.5 to 5 metres per minute. Coupled with multiple oscillating blast guns that perform a synchronised reciprocating motion, it guarantees a highly uniform blasting effect on flat sheets, profiles, and irregular workpieces—achieving a consistency and precision unattainable with manual or batch‑type equipment. The oscillation speed and angle of each gun can be independently adjusted, and the PLC‑based intelligent control system, together with a touch‑screen human‑machine interface, allows all key parameters (blast pressure, oscillation frequency, conveying speed, and processing time) to be digitally preset and stored as recipes. When switching between different workpiece types, one‑touch recall dramatically reduces setup time and minimises reliance on highly skilled operators. In terms of application versatility, this flat‑bed conveyor‑type automatic sandblasting machine is widely employed for removing mill scale and rust from metal sheets, deburring and pre‑coating roughening of automotive parts (e.g., brake discs, engine blocks), creating a matte satin finish on 3C electronic products (mobile phone frames, laptop shells), as well as surface engraving and anti‑slip texturing on non‑metallic materials such as stone, glass, and wood. Whether for pretreatment before electroplating or painting, surface strengthening, decorative finishing, or refurbishing old parts, the machine handles all tasks with high efficiency. In environmental safety and operational economy, this fully automatic continuous conveyor sandblasting equipment integrates an upper‑cyclone separator and a pulse‑reverse cartridge dust collector, achieving 99.99% filtration efficiency for particles down to 0.3μm, with exhaust emissions consistently below 30mg/m³—fully compliant with the strictest environmental regulations. The abrasive recycling rate exceeds 85%, significantly cutting consumable costs. The entire machine features a fully enclosed negative‑pressure blast chamber with double‑layer curtain seals and an automatic wiper for observation windows, effectively preventing dust leakage; operating noise is kept below 75 decibels. All rotating parts are equipped with CE‑compliant safety covers and emergency pull‑cords, enabling rapid shutdown within 0.2 seconds and audible/visual alarms in case of any abnormality, greatly safeguarding operator health and safety. With its continuous high‑throughput production mode and comprehensive ergonomic safety design, this conveyor‑type sandblasting machine not only helps enterprises boost productivity and maintain quality stability, but also stands as the indispensable core equipment for any modern, environmentally responsible surface‑finishing workshop.
