For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] See also Figure 1-3 The utility model provides a technical solution: an air supply structure for a knife-beating cylinder, comprising an air distribution block assembly 1, the bottom of which is respectively connected with a processing air blowing solenoid valve 11 and a spindle air curtain solenoid valve 12, and the air inlet end of the air distribution block assembly 1 is spliced ​​with a filter pressure reducing valve 2, the air inlet end of the filter pressure reducing valve 2 is connected with a first ventilation pipe 4 through a first filter 3, and an air inlet 5 is arranged on the side wall of the first ventilation pipe 4;

[0023] The air outlet end of the air distributor block assembly 1 is spliced ​​with an oil mist separator pressure reducing valve 6, and the air outlet end of the oil mist separator pressure reducing valve 6 is spliced ​​with a second air distributor block 7. The second air distributor block 7 is connected to a second ventilation pipe 9 through a second filter 8, and an air outlet 10 is provided on the side wall of the second ventilation pipe 9.

[0024] Specifically, the air inlet 5 is connected to an external air source, and the air outlet 10 is connected to an external knife-beating cylinder; the gas enters the first ventilation pipe 4 through the air inlet 5, and is discharged from the second ventilation pipe 9 through the air outlet 10 to provide gas power to the knife-beating cylinder after being filtered, accelerated, and decompressed.

[0025] The filter pressure reducing valve 2 adjusts the air pressure of the input in real time. When the pressure at the input end fluctuates, the pressure reducing valve diaphragm automatically adjusts to make the pressure output stable and ensure the pressure stability. At the same time, the oil, water, dust and other impurities in the input air are filtered and removed to increase the service life of the pressure reducing valve diaphragm and the precision of pressure regulation.

[0026] The oil mist separator pressure reducing valve 6 adjusts the air pressure at the air outlet in real time, so that the air pressure entering the output end remains stable, further improving the air pressure stability of the input air, ensuring that the knife cylinder can obtain a stable gas power source, and further filtering impurities such as oil mist in the input air;

[0027] The first filter 3 and the second filter 8 filter the moisture in the air at the air inlet and the air outlet respectively, so as to prevent the moisture in the air input from the air source from causing adverse effects when the air source provides power for the knife-beating cylinder.

[0028] Furthermore, the air distributor block assembly 1 is composed of a plurality of first air distributor blocks 13 , the first air distributor block 13 near the air inlet end is connected to the processing air blowing solenoid valve 11 , and the first air distributor block 13 near the air outlet end is connected to the spindle air curtain solenoid valve 12 .

[0029] Specifically, the gas distributor block is a pressure-bearing component, and different gas source processing components or solenoid valve seats can be connected to the gas distributor block to perform different processing on the air of the gas source, such as acceleration, filtration, etc.;

[0030] The processing air blowing solenoid valve 11 pressurizes the air source input inside to provide greater power for the knife cylinder; the spindle air curtain solenoid valve 12 is used to control the air source at the spindle air curtain hole 19.

[0032] Specifically, the air inlet 17 of the air tank is connected to the air tank, so that the air in the air tank can be introduced into the device from the outside, thereby increasing the air pressure in the device; the air outlet 18 of the air tank is connected to the air outlet tank, so that the air in the device can be diverted into the air tank, thereby reducing the air pressure in the device; the device can be installed on the machine tool through the spindle air curtain hole 19, and an air curtain can be formed by spraying high-speed airflow to isolate the inside and outside of the spindle, thereby preventing impurities such as dust in the air from entering the connection between the spindle and the second air distributor 7, thereby reducing the wear on the spindle during workpiece processing.

[0033] Furthermore, a first mounting frame 14 is installed at the joint of the filter pressure reducing valve 2 and the first filter 3, and a second mounting frame 15 is installed at the joint of the first gas distributor block 13 located at the middle position and the first gas distributor block 13 near the gas outlet end.

[0034] Furthermore, locking frames 16 are installed at the joints of the filter pressure reducing valve 2 and the first air distributor block 13 near the air inlet end, the joints of the first air distributor block 13 near the air inlet end and the first air distributor block 13 located in the middle, the joints of the first air distributor block 13 near the air outlet end and the oil mist separator pressure reducing valve 6, and the joints of the oil mist separator pressure reducing valve 6 and the second air distributor block 7.

[0035] Specifically, the device is fixedly installed by the first mounting frame 14 and the second mounting frame 15; the joints of the various components are locked by the locking frame 16, so that the joints are tighter, thereby ensuring the stability of the entire device during use.

[0036] Working principle and use process of the utility model: After the utility model is installed, the gas enters the first ventilation pipe 4 through the air inlet 5, and the moisture and impurities in the air are initially filtered through the first filter 3, and then the air pressure is stabilized under the action of the filter pressure reducing valve 2 to ensure that the air pressure is output steadily;

[0037] When passing through the oil mist separator pressure reducing valve 6, the oil mist in the gas is separated and the air pressure is stabilized again to ensure that the gas pressure at the second ventilation pipe 9 and the air outlet 10 can be output smoothly, ensuring that the external knife cylinder can provide a stable power source for the mechanical device during operation.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
