The processing is as follows: workers only operate the control system and load and unload the workpiece, and the sandblasting of the workpiece surface is automatically completed by the machine.

The processing sequence is as follows:

1. When sandblasting, the workers put the workpiece on the conveyor belt of the sandblasting machine (for small and light workpieces, customers need to provide their own fixtures).

2. The conveyor belt drives the workpiece to the sandblasting chamber, and the spray gun automatically sandblasting the workpiece according to the required orientation.

3. The processed workpiece will enter the blowing chamber immediately, and the blowing gun will blow away the residual sand dust on the workpiece, and then output it from the other end of the transmission device.

4. The worker removes the workpiece from the output.

5. The machine adopts continuous processing mode.

Features of conveying automatic sand blasting machine:

1. The operation is simple and the efficiency is high. The sand material with different particle size can be replaced according to different process requirements. The sand material can be recycled automatically and the cost can be saved.

2. The conveying speed of the workpiece can be adjusted steplessly according to the process parameters of the workpiece to achieve satisfactory sandblasting effect.

3. The workpiece enters the sandblasting area automatically and sandblasting as required. The sandblasting time can be set according to the sandblasting effect.

4. The spray gun adopts angle swing mode, and can adjust various spray angles to achieve good machining effect.

5. The sand material adopts spiral + wind lifting mode, which can ensure the recycling of sand material.

6. Equipped with filter core type dust collector, it can remove the dust generated in the work.

Shell conveyor for sandblasting

The thickness of steel plate is 5mm-2.5mm. A shield and rubber skin are set at the feeding and discharging ends to prevent dust from escaping. A filter screen is set at the lower part of the engine room to prevent large debris and workpieces from falling into the sand. In the suction chamber, there is a blowing device to clean the sand and dust remaining on the workpiece. The main machine of sandblasting machine is equipped with an observation window, which can observe the whole processing process and deal with emergencies at any time.

Size of sandblasting area: 1200mm (length) × 1200mm (width) × 800mm (height).

Overall dimension: 3800 mm (length) × 1440 mm (width) × 3800 mm (height).

Spray: 12 in 3 groups (swing speed can be adjusted by frequency conversion, and the angle can be adjusted by 360 ° at will);

2. Spray gun swing device:

The swing distance and position of the spray gun can be adjusted according to the sand blasting effect. The swing speed of the spray gun is 15m / min. The swing motor adopts Taiwan Chengbang brand three-phase gear reducer motor with power of 0.75KW. The swing shaft and gun frame of sandblasting machine are made of cold drawn steel, Q235 and 45 ᦇ steel. The heat treatment method is quenching treatment, and the hardness is hrc45.

3. Spray gun group:

This machine is equipped with 12 spray guns, each of which has a group of 4. Spray gun material is aluminum alloy, model: xt-b. The nozzle is made of high quality wear-resistant boron carbide. Nozzle diameter: Ф 8mm. The distance, angle and position of the spray gun can be adjusted according to the user's product needs. It can be set to swing or not to swing. The start-up of each spray gun is controlled separately, and the required number of spray guns can be started according to the processing requirements.

4. Sand collecting hopper:

It is welded by 2.5mm high quality low carbon steel plate, and the surface is sprayed with paint. A filter screen is set in the sand collecting hopper to prevent the workpiece or large foreign matters from falling into the material cabin and blocking the spray gun and affecting the normal operation.

5. Access door:

It is welded by 2.5mm high-quality low carbon steel plate, and its surface is sprayed with paint. It is equipped with an observation window to observe the sandblasting process and deal with unexpected situations at any time.

6. Dust removal system:

The machine is equipped with a set of 6 filter element dedusting boxes, and the Sino Japanese joint venture Phoenix brand special dust removal filter element is prepared. The filtration efficiency is 99% greater than 10 micron particles. It can effectively separate dust and gas, remove dust from work, and greatly reduce the harm to environmental pollution. The waste gas emission can meet the environmental protection emission standard (GB - / t16157-1996): TSP ≤ 120mg / m3.
