The Batch Type Rubber Crawler Shot Blasting Machine is a versatile surface treatment equipment that uses a rubber crawler as the conveying and supporting mechanism for workpieces. It is mainly used for batch surface treatment of small and medium-sized workpieces of various shapes and materials. The equipment has the characteristics of large processing capacity, strong adaptability to workpieces, gentle conveying, and no damage to the workpiece surface. It is widely used in industries such as automotive parts, hardware tools, springs, fasteners, and castings. It can efficiently complete the surface treatment processes such as rust removal, oxide scale removal, surface strengthening, and deburring of workpieces, and is an important equipment to improve the production efficiency and surface quality of batch workpieces.

The working principle of the Batch Type Rubber Crawler Shot Blasting Machine is based on the centrifugal shot blasting principle. The core components include the shot blasting wheel, rubber crawler conveyor, shot recycling system, dust removal system, and control system. During the working process, the workpieces to be processed are placed in the rubber crawler chamber in batches. The rubber crawler is driven by the motor to rotate, and the workpieces are continuously turned over and conveyed forward in the crawler chamber. At the same time, the shot blasting wheel rotating at high speed projects the shot material onto the surface of the workpieces. Due to the continuous turning of the workpieces driven by the rubber crawler, every part of the workpiece surface can be uniformly impacted by the shot material, so as to achieve the purpose of uniform surface treatment. After the shot blasting is completed, the workpieces are conveyed to the discharge port by the rubber crawler for unloading. The shot material and the debris generated during the processing are separated by the shot recycling system, and the clean shot material is recycled to the shot blasting wheel for reuse. The dust generated during the shot blasting process is collected and treated by the dust removal system to meet the environmental protection emission standards.

The structural design of the Batch Type Rubber Crawler Shot Blasting Machine is mainly focused on improving the adaptability to workpieces and processing efficiency. The main body of the machine is made of high-strength steel plate, which is welded with high precision and undergoes stress relief treatment to ensure the overall rigidity and stability of the equipment. The rubber crawler is a key component of the equipment. It is made of high-quality wear-resistant rubber material, which has good elasticity and wear resistance. The surface of the crawler is usually designed with a special pattern to increase the friction between the crawler and the workpiece, ensuring that the workpiece can be fully turned over during the conveying process. The crawler chamber is lined with wear-resistant rubber plates, which can effectively reduce the impact and wear of the shot material on the chamber body, and at the same time avoid scratches on the workpiece surface. The shot blasting system of the equipment is usually equipped with multiple shot blasting wheels, which are arranged above and on both sides of the crawler chamber to ensure that the shot material can cover the workpiece surface comprehensively. The shot blasting wheel is made of high-wear-resistant alloy material, which has a long service life. The shot recycling system consists of a screw conveyor, bucket elevator, separator, and shot storage bin. The screw conveyor conveys the mixture of shot material and debris to the bucket elevator, which lifts the mixture to the separator. The separator separates the shot material from the debris through wind force and gravity, and the clean shot material falls into the shot storage bin for reuse. The dust removal system adopts a bag filter or cartridge filter, which has high dust removal efficiency and can effectively remove the dust generated during the shot blasting process.

The control system of the Batch Type Rubber Crawler Shot Blasting Machine adopts PLC control technology and touch screen human-machine interface, which is easy to operate and has high control precision.
