Overview of the Functions of the Carriage Shot Blasting Machine
The carriage shot blasting machine is a large-scale steel structure roller conveyor-type shot blasting cleaning system. It represents advanced specialized equipment designed and manufactured to meet specific user requirements. This machine is particularly suitable for comprehensive shot blasting cleaning of large-sized steel structural components, such as trailer chassis, car carriages, and heavy-duty truck carriages. Through shot blasting cleaning, not only can rust, oxide scale, dirt, and other surface contaminants be effectively removed, but the process also restores the metallic luster of the workpiece surface, alleviates internal stress, enhances fatigue resistance, and improves paint adhesion when the workpiece is coated. Ultimately, this achieves the dual objectives of enhancing both the surface and internal quality of the workpiece.
The vehicle body, frame, and trailer chassis are critical components of automobiles, characterized by relatively large dimensions and specifications. Rust removal and cleaning have traditionally posed significant challenges in this domain. Prior to painting, shot blasting machines are employed to remove sand and oxidation from these components.
The car body cleaning solution utilizes roller conveyor through-type shot blasting machines, significantly reducing worker labor intensity while mitigating potential safety hazards.
Introduction to Car Compartment Shot Blasting
For car compartment cleaning, our company, drawing on years of user experience, recommends the use of roller conveyor-type shot blasting machines. The process involves the following steps:
1. Place the car compartment on the roller conveyor system.
2. The machine transports the compartment into the shot blasting cleaning chamber.
3. Within the chamber, the shot blasting machine propels steel shots at high velocity. These steel shots impact the metal surface of the car compartment, effectively removing impurities such as sand, iron oxide, and rust, thereby improving the quality of the metal surface.
4. The process increases the roughness of the metal surface, enhancing the adhesion between the applied paint and the metal surface of the car compartment. This step is integral to the anti-corrosion treatment of the car compartment.
5. The machine is equipped with a dust collector, ensuring compliance with stringent national environmental protection inspection standards and eliminating concerns regarding dust pollution.
The frame shot blasting machine comprises a shot blasting cleaning chamber, a shot blasting machine assembly, a shot material circulation purification system (including screw conveyors, elevators, separators, and shot control systems), a roller conveyor system, a purging mechanism, a maintenance platform, a dust removal system, a pneumatic control system, and an electrical control system. Utilizing a continuous roller conveyor for workpiece transportation, the machine enables simultaneous loading/unloading and shot blasting cleaning operations, markedly improving operational efficiency.
The electrical control system of the carriage shot blasting machine features an automatic/manual switching function and incorporates safety protection mechanisms such as electrical interlocks, self-locking, and fault alarms to ensure safe equipment operation. Additionally, the system supports advanced functionalities like PLC human-machine interface, fault detection, and alarm notifications.
