5. Electronic parts processing: matte surface and etching of the chip, removal of impurities on the back of the wafer, overflow of electronic parts packaging, removal of printing on the surface of finished products, and cleaning of ceramic heating.

(1) Mould processing: sandblasting of general mould surface, matte treatment after mould bite flower, wire cutting mould, glass mould, tire mould, conductive rubber mould, Shoe mold, bakelite mold, electroplating mold, button mold, plastic product mold.

(2) Processing of large workpieces: large workpieces, such as: oil tank, chemical tank, ship hull, copper structure, iron house, container, automobile industry, etc. rust removal, paint removal, maintenance and large-scale Automatic matte treatment of flat glass. This sandblasting machine is suitable for sandblasting of large flat glass, iron, aluminum and other metals, and non-metallic sheet materials.

2. Installation instructions:

(1) Select a site: The sandblasting machine should be installed in a place with good ventilation, dry site, access to power supply, and convenient air source.

(2) Select the power supply: The power supply used by the sandblasting machine is AC380V, 50HZ AC, and the power switch is 4P, 40A air switch.

(3) Select the air source: the air inlet pipeline of the sandblasting machine should use iron pipes of 1 inch or more for air supply, and the air source needs to be dry and clean.

(4) The site, the power supply and air supply are ready, please check the screws and parts of the machine to see if they are loose or smashed. If so, please fix them firmly, or update new products.

(5)Put the dust collector against the back of the main unit, and connect the vacuum tube and power supply to the main unit.

(6)Turn on compressed air. (7)Turn on the mains power. (8)The installation is complete.

(9) with installation parameters

1. Turn on the power supply after the assembly is completed, and check whether the phase sequence of the power supply is correct. If the phase sequence is disordered, just replace any two positions of the three-phase power cord. Fourth, the test operation steps of the sandblasting machine

2. Start the fan and check whether the fan rotates in the correct direction. If the fan is reversed, switch any two positions of the power wires of the fan.

3 After the fan is started, slowly pour an appropriate amount of sand into the machine.

4. Turn on the air inlet switch, pull out the adjustment knob of the pressure regulating valve gently, adjust it according to the direction specified on the knob, refer to the pressure gauge to adjust the air pressure you need, and press the knob after the adjustment. Lock down, turn to “ten ” or “H” when adjusting to increase the air pressure, and turn to “ A " or "L" rotation will lower the air pressure.

Note: When the knob of the pressure regulating valve cannot be adjusted, do not forcibly rotate it, otherwise the pressure regulating valve will be damaged.

(1) Start the conveyor belt and start the swing of the spray gun, turn on the spray gun switch, and check the sand output.

(2) After the sand production is normal, the test machine is completed.

Five, the operation of sandblasting machine

1, sand adding: start the dust collector and slowly pour the sand material into the sand blasting machine. The amount of sand added for the first time is about 50-60kg. During the blasting process, the sand material will be consumed, so an appropriate amount of new sand needs to be supplemented in the blasting process so that enough sand material can be circulated in the machine and the uniformity of the sand material particle size can be maintained.

Note: (1) When the new machine is used for the first time, it is necessary to clean up the residual iron filings and other impurities and sundries in the machine.

        (2) The amount of sand added should not be too much, nor too little, and always keep about 50-60kg sand in the machine span>Material.

2. Before each operation, the condition of each spray gun must be checked to see if it is necessary to replace the nozzle, sand pipe and other vulnerable materials. Then, start the swing motor and turn on the switch of each spray gun separately. Check whether the sand output is normal.

3. After the inspection, set the transmission speed after the inspection is normal, start the dust collector, start the swing of the spray gun, start the conveyor belt, turn on the switch of the spray gun, and then the sand blasting can be started. Put in the product, and remove the processed product from the discharge port.

4, dust cleaning operation of the dust collector: the dust collector should be shut down for cleaning once every 4 hours of operation, and the fan blades should be completely stopped during cleaning. The most effective cleaning method is After every day of use, open the door of the dust collector, tap the cloth tube several times and shake the cloth tube lever, then open the lower cover of the dust collector to release the collected dust.

5, sand discharge operation: start the dust collector to discharge the 3 inch plug at the lower end of the separator, and the sand will flow out.

6. Safety instructions and precautions for sandblasting machine

1, please read the operation manual carefully before operation.

2, the input pressure of sandblasting machine should not exceed 8kg/cm2

3 Please wear safety gear and gloves, goggles, earmuffs (or earplugs), safety shoes, etc. before operation.

4. When operating, the owner must be trained to be able to work, and it is strictly forbidden to operate this machine after drinking.

5. It is forbidden to use toxic and corrosive abrasives.

6. The sandblasting machine should be grounded reliably to avoid electrostatic accumulation.

Seven, sandblasting machine maintenance and precautions

1, the sandblasting machine is a machine with a lot of dust, so it is necessary to keep the machine clean and tidy, especially cleaning bearings and electrical motors.

2. The bearings need to be lubricated to prevent dry grinding, and oil needs to be refueled once a month.

3, the belt bracket and the gun rocking rod in the sandblasting machine are consumables, and can be wrapped with rubber during maintenance. Check the wear level every 8 hours of work, and find that the rubber is worn too much When it is large, please replace it in time.

4, the nozzle is a consumable item. When the nozzle diameter is worn to 11MM, it needs to be replaced. The service life of the nozzle is different from the material of the nozzle (the service life of the tungsten steel nozzle is about 70 hours, the service life of domestic boron carbide nozzles is about 300 hours, and the service life of better boron carbide nozzles is about 800 hours)

5, the spray gun is a consumable item, every 100 hours of operation, please balance and rotate the air core of the spray gun by 45. Horn. Let the air core wear evenly on each surface, which can greatly prolong the service life of the spray gun. The sand core of the spray gun is the most easily worn part. Every 24 hours of work, it is necessary to check whether the sand core is broken or perforated. If there is perforation, replace the sand core in time to ensure normal sandblasting.

6, sand pipes are consumables, and the normal wear time is about 250 hours. Therefore, the wear and tear must be checked before starting the machine every day. In addition, please pay attention to the sand pipes during the use of the machine. Try not to rub against each other with other parts to avoid abnormal wear.

7. The place where the rubber is attached to the inside of the sandblasting machine is particularly prone to wear. After working for 8 hours a day, please check the wear degree of each rubber plate. If you find severely worn parts, you must immediately attach a rubber sheet to protect the body.

8, When the machine is running, turn off the light to reduce the load of the electric box. The main function of the light is to adjust the position of the spray gun, repair the machine and check the sand production of the spray gun.

9, dust collector maintenance, every 4 hours of operation, the dust collector needs to be shut down to clean up the dust of the dust collector. can be installed later.

Note: Frequent cleaning is of great help to the dust collection effect. If the dust is not cleaned in time, the machine will be blocked.

8. Common faults and troubleshooting methods of sand machine

1, can not spray sand

NOTE: When checking the gun suction, be sure to have the nozzle on.

2, poor vacuuming

3, the machine does not start
