The Disa DSL326 tumble belt shot peening machine is an efficient equipment specially designed for surface cleaning and strengthening treatment of small and medium-sized workpieces. With stable performance, automated operation processes and a closed-loop medium circulation system, it is widely used in industries such as machinery manufacturing, auto parts, and hardware tools. It can quickly remove oxide scales, rust, oil stains and impurities on the surface of workpieces, improve the surface roughness of workpieces, and lay a high-quality foundation for subsequent processes such as painting and electroplating.

I. Composition of Core Structure

The core structure of the equipment is precisely coordinated to ensure efficient and stable operation, mainly consisting of five core components: the main machine serves as the main supporting structure of the equipment, carrying the core processes of workpiece processing; the drum, as a component for carrying and moving workpieces, realizes the separation of abrasives and workpieces through a perforated design; the process oscillation device provides stable oscillation power for the spray gun to ensure uniform abrasive spraying; the spiral dust collector (including a spiral separator) undertakes the dual functions of dust filtration and abrasive recovery; the electrical control box realizes full-process automatic control and accurately regulates the operation rhythm of each component.

II. Automated Operation Process

The equipment adopts a user-friendly automated design with a clear and easy-to-understand operation process, requiring no complex manual intervention. The specific steps are as follows:

1. Loading Stage: Open the equipment door, place the workpieces to be processed evenly into the drum inside the box, ensuring that the placement of the workpieces does not exceed the load-bearing range of the drum.

2. Operation Startup: After closing the door, start the machine through the electrical control box. The drum then runs forward, driving the workpieces to roll smoothly inside the box to ensure that all surfaces of the workpieces can be processed evenly.

3. Sandblasting Treatment: Simultaneously turn on the oscillating device of the process spray gun. The abrasive is uniformly sprayed out through the spray gun under the drive of high-pressure gas, impacting and cleaning the surfaces of the rolling workpieces.

4. Precise Timing Control: When the sandblasting operation reaches the preset time, the sandblasting action stops automatically, and the equipment switches to the gas blowing stage to remove the residual fine abrasives and dust on the surface of the workpieces.

5. Operation Conclusion: When the gas blowing reaches the preset time, the blowing action stops, the oscillating device of the process spray gun is turned off simultaneously, and then the drum stops running, completing the workpiece cleaning process.

6. Unloading Stage: When the door is opened, a linkage switch is triggered, and the drum automatically runs in reverse to smoothly send the processed workpieces out of the box; after all workpieces are sent out, the drum stops automatically, and closing the door completes a single operation cycle.

III. Closed-Loop Medium Circulation System

The equipment is equipped with an efficient closed-loop medium circulation system, which not only significantly improves the utilization rate of abrasives and reduces the cost of consumables, but also effectively reduces dust pollution, achieving green and environmentally friendly operations. The circulation process is as follows:

1. Abrasive falling: The abrasives sprayed during the sandblasting operation directly fall into the lower storage hopper through the perforated plate of the drum, realizing the initial separation of abrasives and workpieces.

2. Recovery and transportation: The abrasives in the storage hopper are quickly sucked back by the spiral dust collector through a dedicated recovery pipe to avoid waste caused by abrasive accumulation.

3. Dust filtration: The sucked-back abrasives enter the spiral separator, and through the precision filtration structure of the separator, the dust and impurities mixed in the abrasives are effectively separated to ensure the purity of the abrasives.

4. Circulation and reuse: The filtered clean abrasives are re-transported to the process spray gun by the spiral separator, realizing the closed-loop circulation and reuse of abrasives without the need for frequent replenishment of new abrasives.

IV. Core Advantages and Highlights

1. High degree of automation: The entire process is precisely controlled by the electrical control box, and the operations from workpiece loading, processing to unloading are all automated, which greatly reduces labor costs and improves work efficiency.

2. Uniform processing effect: The forward rotation of the drum drives the workpiece to roll, and with the spray gun oscillation device, it ensures that the abrasives evenly cover all surfaces of the workpiece, resulting in consistent cleaning and strengthening effects.

3. Energy saving and environmental protection: The closed-loop medium circulation system improves the utilization rate of abrasives and reduces the waste of consumables; the spiral dust collector effectively filters dust, reduces environmental pollution, and meets environmental protection requirements.

4. Convenient and safe operation: With the box door linkage switch design, when the box door is opened, the drum automatically reverses to discharge materials, and the operation can only be started after closing the box door, ensuring the safety of operators; the operation steps are simple, and no professional skills are required to get started quickly.
