1.principle of operation
SME-750 pneumatic steel mesh cleaning machine is a new and high-performance SMT steel mesh cleaning equipment with compressed air as energy source. Manually put the steel mesh into the cleaning room, adjust the cleaning and drying time, close the door and press the start switch, and the steel mesh will be automatically cleaned and dried. Stop running automatically when the set time arrives; The time to open the door is reset, so as to realize the next workflow. This machine is convenient for operators to clean steel mesh and greatly improve production efficiency; Among them, because the liquid used for cleaning can be recycled in this machine, the consumption and cost of the liquid are greatly reduced, the operation time is greatly shortened, and the operator does not need to touch the liquid, which will not harm the human body.
The power source used in this machine is compressed air, which does not need any power input, so that its safety performance reaches 100% and there is no requirement for liquid. All control elements are imported brands, which make the machine run stably and have a long service life, and reduce the after-sales service after the warranty period. The waste gas generated by drying is discharged through the exhaust device with special structure inside the machine, which reduces the volatilization of liquid, reduces the consumption of liquid and compressed air, and does not emit liquid odor.
2.And its structural characteristics
1)The machine adopts double-layer door sealing design, with the edge of sealant, which has good sealing performance and can effectively reduce the environmental pollution caused by gas and liquid overflow;
2)Clean the transparent liquid level window and liquid level sign of the liquid tank, which is convenient for operators to observe the changes of liquid level and water quality at any time;
3)The machine is made of high-quality SUS304 material, which has strong corrosion resistance and good temperature resistance;
4)Smooth rotating spray design, strong plate washing ability;
5)The liquid pressure can be displayed by the panel pressure gauge, and the cleaning pressure can be adjusted independently, which is suitable for any material screen;
6)Unique exhaust design, lower liquid consumption;
7)All door panels of the machine are attached with sound insulation cotton to reduce noise and improve the working environment;
8)
The bottom of the cylinder is inclined, so that the liquid in the cylinder can be completely drained, which is more convenient for cleaning and maintenance.
3.Pneumatic control characteristics
1)The master control box is centrally controlled and placed on the machine operation surface to facilitate the operation control and maintenance of the machine;
2)The machine is controlled by automatic counter, which makes the operation simple and clear, and reduces the difficulty of employee training;
3)The indicator light and pressure gauge are designed to ensure that the staff can accurately understand the running status of the equipment. When the machine is abnormal, the indicator light will be displayed in red, but the indicator of the pressure gauge will not indicate correctly;
4) Install a protective device at the main entrance of the machine to prevent danger caused by forgetting to close the door due to human factors;
5)Both liquid recovery and discharge are filtered by three stages, which effectively reduces the production cost and meets the discharge requirements;
6)The air pressure regulating filter is installed at the side door, and the air pressure parameters can be adjusted according to products with different specifications;
7)The whole machine adopts pneumatic control to prevent any fire or personal safety accident.
4.Characteristics of spray filtration system
1)The nozzles are installed at an angle of 5 ~ 15, and the spraying is uniform and overlapping is avoided;
2)
Quick nozzle installation, easy installation, disassembly and cleaning;
3)The spray is equipped with a pressure gauge, which can facilitate inspection and adjust the appropriate spray pressure;
4)
The double filtering design of the filter device of the liquid tank and the filter screen at the lower layer of the spray chamber not only effectively filters the dregs in the cleaning liquid and the rinsing liquid to prevent the liquid pump and the nozzle from being blocked, but also greatly improves the use efficiency of the liquid.
