[0002] A rotary blow molding machine is a device that uses a blow molding process to make plastic particles into hollow containers. Common models include a one-step extrusion blow molding machine that uses PP and PE, a two-step injection stretch blow molding machine that uses PET, PC or PP, and newly developed multi-layer hollow extrusion blow molding and stretch blow molding. Most blow molding machines are still two-step blow molding machines, that is, the plastic raw materials must first be made into bottle blanks and then blown.

[0003] The high-pressure air generated by the air compressor contains a large amount of water, dust or oil, and the compressed air directly enters the bottle blowing machine, which not only easily damages the electronic components and shortens their service life, but also enters the bottle blank and affects the product quality. Utility Model Content

[0004] The purpose of the utility model is to provide a high-pressure air processing system for a bottle blowing machine, which performs gas-liquid separation, filtration and deodorization on the compressed air through a post-processing component, thereby solving the problem that the existing compressed air directly enters the bottle blowing machine, easily causing damage to electronic components and entering the bottle blank, thereby affecting product quality.

The compressed air is filtered by the filter B and then passes into the blowing working end.

[0011] As a preferred technical solution of the present invention, an air flow meter and a high-pressure ball valve are connected in series to the air inlet end of the filter A.

[0012] As a preferred technical solution of the present invention, a safety valve is connected in series to the air outlet end of the filter B.

DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0026] See also Figure 1 and 2 As shown, the present invention is a high-pressure air processing system for a bottle blowing machine, including an air compressor unit, which includes a screw air compressor 1, a first air tank 2, a booster 3, a second air tank 4, a post-processing assembly 5, and a third air tank 6, which are sequentially connected in series in a compressed air pipeline. The screw air compressor 1, the first air tank 2, the booster 3, the second air tank 4, the post-processing assembly 5, and the third air tank 6 are all mounted on the same base platform 8, allowing for overall mobility, transportation, and convenient disassembly.

[0027] Furthermore, the first, second, and third gas tanks 2, 4, and 6 are arranged in a row, making it easier to inspect and maintain each tank simultaneously. Each tank is equipped with a pressure gauge, a safety valve on top, and an automatic drain valve at the bottom. Each drain valve is connected by a hose and fed into a sewage pipe.

[0028] The compressed air generated by the screw compressor 1 enters the air tank 2 and then enters the booster 3, where the air pressure is increased to the high pressure standard for bottle blowing. The air then passes through the second air tank 4, the post-processing component 5, and the third air tank 6 before entering the bottle blowing machine.

[0029] like Figure 3 As shown, the post-processing component 5 includes a gas-liquid separator 501, a primary filter 502, a freeze dryer 503, a secondary filter 504, a tertiary filter 505 and a deodorizing filter 506 which are sequentially connected in series through pipelines.

[0030] The compressed air enters the gas-liquid separator 501 from the second gas storage tank 4 , and the gas-liquid separator 501 separates a large amount of water, which is discharged from the automatic electronic drain valve at the bottom and then enters the primary filter 502 .

[0031] The filtration precisions of the primary filter 502, the secondary filter 504, and the tertiary filter 505 increase in order. For example, the filtration precision of the primary filter 502 is 1 μm, and the residual oil content after filtration can reach 1 ppm. The filtration precision of the secondary filter 504 is 0.1 μm, and the residual oil content after filtration can reach 0.1 ppm. The filtration precision of the tertiary filter 505 is 0.01 μm, and the residual oil content after filtration can reach 0.01 ppm.

[0032] The filtration accuracy of the three filters increases sequentially, achieving step-by-step filtration of the compressed air and improving the filtration effect. This significantly reduces the water and oil content in the compressed air, preventing water and oil accumulation inside the solenoid valve and cylinder of the bottle blowing machine, which could damage electronic components. This effectively extends the service life of the entire equipment and effectively ensures product quality.

[0033] like Figure 4 As shown, compressed air filtered by post-processing assembly 5 enters third air storage tank 6 and then enters the blow molding machine. The blow molding machine is equipped with an internal reprocessing assembly 7, which includes filters A701 and B702 connected in series. The compressed air is filtered by filter B702 before entering the blow molding machine. Furthermore, an air flow meter 703 and a high-pressure ball valve 704 are connected in series to the inlet of filter A701, and a safety valve 705 is connected in series to the outlet of filter B702.

[0034] The compressed air passing through the air flow meter 703 can display the specific pressure and flow rate, and the high-pressure ball valve 704 can close the inlet and outlet of the compressed air, making it convenient to properly shut down the equipment for maintenance.

[0035] Filter A701 has a filter element precision of 0.01 μm, reducing residual oil to 0.01 ppm after filtration. Filter B702 has a filter element precision of 0.01 μm, reducing residual oil to 0.003 ppm after filtration. The purified compressed air then passes through safety valve 705 and piping into the blow molding machine for bottle blowing. Adding the internal reprocessing component 7 further enhances the compressed air purification and drying effects.

[0036] Safety valve 705 can prevent the gas pressure in the pipeline or device from exceeding the specified value, thereby achieving the purpose of safety protection. Its opening and closing parts are in a normally closed state under the action of external force. When the gas pressure in the equipment or pipeline increases and exceeds the specified value, it automatically opens. By discharging gas to the outside of the system, it prevents the pressure in the pipeline or equipment from exceeding the specified value, playing an important protective role in personal safety and equipment operation. This part can operate independently. When an alarm is sounded, the ball valve can be closed to disconnect the high-pressure gas. It is easy to maintain and components can be replaced in time, saving time and cost.
