The equipment adopts a horizontal through-type structure design, mainly composed of a mesh belt conveyor system, shot blasting chamber, shot circulation system, dust removal system, and electrical control system. The mesh belt is woven from high-strength wear-resistant steel wire and equipped with an automatic tensioning device to ensure smooth and reliable conveying. Multiple high-efficiency shot blasters are arranged inside the shot blasting chamber, allowing for uniform treatment of workpieces from different angles.
The QWD series equipment has significant advantages in processing thin-walled and brittle parts. Its unique mesh belt conveyor method keeps workpieces stable during transport, effectively preventing collisions. By adjusting the power of the shot blasters and the mesh belt speed, the shot blasting intensity can be precisely controlled to meet the processing requirements of workpieces of different materials. The equipment achieves a surface cleanliness level of Sa2.5 on processed workpieces while maintaining original dimensional accuracy.
This equipment is particularly suitable for the following industries:
Automotive Parts: Aluminum alloy housings, thin-walled castings, etc.
Precision Casting: Small castings, stainless steel parts, etc.
Electronics & Electrical Appliances: Ceramic components, insulating parts, etc.
Aerospace: Precision parts, special alloy parts, etc.
Daily Hardware: Tools, locks, and other small parts.
The equipment adopts a modular design, with various conveyor belt widths available from 400 mm to 2000 mm, and a processing height range of 50-150 mm. The conveyor speed is steplessly adjustable via a frequency converter, ranging from 0.5-5 m/min. The equipment is equipped with a high-efficiency dust removal system, with emission concentrations below 15 mg/m³, and operating noise controlled below 80 decibels.
The equipment features strong continuous operation capability and a high degree of automation. Workpieces are continuously conveyed via the conveyor belt, enabling uninterrupted production. A unique shot blasting circulation system ensures a shot purity of over 99%, significantly reducing operating costs. The equipment is equipped with an intelligent control system that monitors the operating status of each component in real time.
The equipment features multiple safety protection devices, including an emergency stop button, overload protection, and access interlocks. An automatic conveyor belt misalignment detection system promptly adjusts the conveyor belt position to prevent equipment damage. The dust removal system is equipped with a spark-proof device to ensure production safety.
Equipment maintenance is convenient. Routine maintenance mainly includes checking the conveyor belt tension, inspecting worn parts of the shot blasting unit, and cleaning the dust removal system. Key components adopt standardized designs, making replacement easy and effectively reducing maintenance costs.
