High degree of automation: simple structure, automation of all operation processes, less and simple personnel operation
Flexible transportation mode: the customer can choose the transportation mode according to the workpiece: roller pass through or rotary table, and press the button to automatically discharge and feed
Adjustable spray gun speed: stepless speed regulation can be controlled by frequency converter according to sand blasting effect
Good sand blasting effect: the surface will not produce scratches, indentations, "s" line, yin and Yang surfaces and other defects
Low operation cost: the cyclone separator is used for sand return, which can fine tune the separation of sand materials between 150 #-320 # and reduce abrasive loss
Environmental protection standard: cyclone dust collector and filter element dust collector are used for secondary dust removal, with a dust removal rate of more than 95%, which is absolutely in line with the national environmental protection requirements
Rotary automatic dry sand blasting machine: suitable for automatic sand blasting of the inner and outer surfaces of disc, column and square workpieces, such as handicrafts, baking pans, glass lampshades, non stick pots, communication equipment and other workpieces.
Roller pass automatic dry sand blasting machine: it is suitable for sand blasting of relatively regular workpieces such as flat plate, square, plate, profile, such as: plate, aluminum plate, profile, ordinary steel plate, panel, glass plate, stone, computer motherboard, non stick pot, computer chassis, baking pan, toaster, etc.
The sand blasting operation of the full-automatic dry sand blasting machine is to use the spray gun and lighting to operate in the sand blasting work box. Most of the abrasives are recovered in the form of pneumatic force. The air purification device includes dust bag, bag dust collector and filter cartridge dust collector. When the workpiece is cleaned in the sand blasting box, the fan of the ventilation and dust removal system makes the whole system in a negative pressure state, and the outside air enters the sand blasting box through the air inlet on the sand blasting box to remove dust and fine abrasives, Reusable abrasives and impurities generated by blast cleaning are sucked into the abrasive recovery / separator. Abrasives and impurities are first separated from dust and fine abrasives in the abrasive recovery / separator. Reusable Abrasives enter the storage hopper through the filter screen for storage. The air, with dust and fine abrasives, enters the dust removal device for purification and is discharged into the atmosphere.
The full-automatic dry sandblasting machine room is welded with 3mm thick high-quality carbon steel plate and 100*100 square steel, and the lining is 3mm thick rubber plate to protect the service life of the room. |  |
 | With independent sandblasting part, the abrasive capacity is greatly improved, and different tank diameters are available. Customers can choose the corresponding model according to the actual application; The pressure tank container of sandblasting machine is welded from boiler steel plate. All welds shall be subject to magnetic particle inspection and pressure test. The technical indexes fully meet the national safety technical index standards. The tank surface shall be painted (two layers of antirust paint and one layer of finish paint). The middle of the tank is equipped with an access hole to facilitate workers' assembly, disassembly and maintenance. The sand volume control valve adopts manual control, and the operator can adjust the air flow and sand flow according to the sand blasting requirements, so that the air flow and sand flow can get an ideal mixing ratio, and improve the efficiency of sand blasting. |

The main function of the sand valve is to control the opening and closing of the sand material, and adjust the sand blasting volume infinitely. It is installed at the bottom of the sand blasting host. The nine way adopts the imported clemco pneumatic control sand blasting valve, and the air clamp control mode, which has the advantages of high accuracy, large sand production, uniform sand production, convenient adjustment, safety and reliability, long service life (more than 3000 hours). Customers can also choose Thomson or domestic sand valves. | The function of the rotary feeding valve is to control the opening and closing of the sand and adjust the sand blasting flow. It is installed on the top of the sand blasting host. It has a jacket structure. The driving part is a diaphragm cylinder, which has stable and reliable performance, almost no maintenance, large sand output and sensitive control. In addition, the material level sensor is installed on the sand blasting tank, which is conducive to the personnel to identify the sand adding amount of the sand blasting tank. When the sand reaches the set value, the rotary feeding valve automatically closes, which is simple and efficient. | The main function of the stop valve is to close the stop valve when the rotary charging valve is replaced or repaired, so that it is not necessary to discharge all the sand when replacing and repairing the rotary charging valve, which saves time and effort. | The independently developed and designed high-speed sandblasting gun, venturi shaped nozzle, is made of boron carbide, with a long service life of 800-1000 hours; Compared with the ordinary spray gun, the venturi spray gun has faster sand blasting speed, 50% higher working efficiency, and the working efficiency can reach 35m2/h, with small recoil force, high efficiency and labor saving. | Wear resistant special sand blasting pipe is adopted, and the model is φ 32*51*20m, one end of the sand blasting pipe is equipped with a flexible and convenient quick connector, and the other end is equipped with a nozzle connector. |
The wind speed and pressure of the dedusting fan are used to recover the shot and some dust, and then the different gravity of the shot and dust and the friction of the separator are used to separate the dust and shot. The dust is discharged directly after being dedusted by the cyclone bag filter, while the useful shot is retained in the hopper for re shot blasting. The waste generated during shot blasting is filtered out by the screen of the cyclone separator, and the whole process is automated, The separation effect of dust and pellets is good, and the waste gas meets the national emission standard. |  |
 | Automatic dry sand blasting machine is welded with high-quality steel plate folding! The transmission and drive adopt plane thrust bearings and deep groove ball bearings. Double sided dust-proof bearings can be used in large dust to ensure long-term use of bearings! In addition, the bearing of the drive wheel is protected by a dust cover! Add thickened rubber plate on the surface of the bearing workpiece of the rotary table, and φ 5mm holes with a spacing of 20 × 15mm for the recovery of sand. |
The filter cartridge structure is adopted, and the filter material of the filter cartridge is a new material produced by Donaldson technology. The filter material is 100% polyester fiber, with a thickness of 0.80mm, the highest heat resistance: 80 ℃, air permeability: 220m3/m2/h, weight: 260g/m2, filtration accuracy: 5um-10um, filtration resistance: ≤ 46pa, filtration efficiency: ≥ 99.99%. The filter cartridge is made of folded cylindrical structure, with an outer diameter of 325mm, an inner diameter of 220mm, and a barrel height of 660mm. The filtering area of a standard filter cartridge is 15m2, while the filtering area of a bag type dust collector of the same size is only 1m2, which greatly reduces the volume of the dust collector. |  |
 | The electrical control system of the full-automatic dry sandblasting machine adopts brand electrical, the main original components adopt domestic first-line brands, the low-voltage electrical adopts Schneider, the proximity switch and photoelectric switch adopts Omron, the travel switch and foot switch adopt Korean Kaikun, and the PLC control panel can set and display the swing speed of the spray gun, sandblasting time, remaining time, purging time, etc. |
