[0026] Reference Figure 1-2 The valve seat of the bottle making machine comprises an upper valve seat 1 and a lower valve seat 2 fixed on the lower side of the upper valve seat 1. A plurality of solenoid valve mounting positions are arranged on the upper side of the upper valve seat 1, and solenoid valve inlet and outlet holes 3 are arranged at the solenoid valve mounting positions. Transverse distribution air passages 4 are opened on both sides of the upper valve seat 1, and the inner ends of the distribution air passages 4 are connected to the solenoid valve inlet and outlet holes 3. An upper branch air passage 10 connected to the middle part of the distribution air passage 4 is arranged on the lower side of the upper valve seat 1, a lower branch air hole 15 connected to the upper branch air passage 10 is arranged on the upper side of the lower valve seat 2, a slip ring air passage connecting hole 7 is arranged on the lower side of the lower valve seat 2, and a lower branch air passage connecting the lower branch air hole 15 and the slip ring air passage connecting hole 7 is arranged inside the lower valve seat 2.

[0027] Multiple solenoid valve installation positions are arranged along the length direction of the upper valve seat 1. An air supply channel 5 is opened in the middle of the upper valve seat 1. The air supply channel 5 is arranged along the length direction of the upper valve seat 1. The air supply channel 5 is connected to the air inlet holes in all the solenoid valve inlet and exhaust holes 3. Throttle valves are arranged at the air distribution channels 4 on both sides of the upper valve seat 1. The two opposite air distribution channels 4 are the air inlet channel and the exhaust channel respectively. The speed of the action of each cylinder is controlled by synchronously adjusting the two oppositely arranged throttle valves.

[0028] A bottle blowing air supply passage 11 is provided on one side of the lower valve seat 2, and the bottle blowing air supply passage 11 is connected to the slip ring air passage connection hole 7. A bottle blowing air supply solenoid valve is provided at the bottle blowing air supply passage 11 for controlling the air supply on and off of each bottle blowing station.

[0029] A slip ring connection groove 6 is provided on the lower side of the lower valve seat 2, and a lower air hole 15 is provided in the slip ring connection groove 6. During installation, the slip ring is installed in the groove 9, and the lower air hole 15 is connected to the slip ring air passage of the slip ring, and the compressed gas is sent into the slip ring and finally delivered to the bottle making station, or the compressed gas discharged from the bottle making station is sent into the air distribution passage 4 of the upper valve seat 1 or the bottle blowing air supply passage 11 of the lower valve seat 2 after passing through the slip ring, and the compressed gas is discharged, and the intake pressure or exhaust pressure is adjusted by the throttle valve to meet the molding requirements of glass bottle making.

[0030] A plurality of slip ring connection holes for connecting the slip rings are also provided in the slip ring connection groove 6. Bolts pass through the slip ring connection holes to fix the outer ring of the slip ring. The outer ring of the slip ring is fixedly arranged, and the inner core shaft is rotatably arranged. The lower part of the lower valve seat 2 is formed with a larger non-porous space by using the air distribution channel 4 and the lower flow channel in the lower valve seat 2, so as to facilitate the installation of the core shaft.

[0031] A groove 9 is provided in the middle of the lower side of the upper valve seat 1, and a connecting hole 8 is provided on the lower side of the upper valve seat 1. The connecting hole 8 connects the solenoid valve inlet and exhaust holes 3 and the distribution flow duct 4. The connecting hole 8 is arranged in the groove 9. When processing the upper valve seat 1, the solenoid valve inlet and exhaust holes 3 are connected through the connecting hole 8, and then the distribution flow duct 4 is processed from the side of the upper valve seat 1 until it is connected with the connecting hole 8, thereby realizing the connection between the distribution flow duct 4 and the solenoid valve inlet and exhaust holes 3. After completion, the lower ends of the connecting holes 8 need to be sealed respectively with bolt seals in the future. The setting of the groove 9 facilitates the installation of the bolts.

[0032] See also Figure 3-6 Some lower branch flow channels are directly connected downward to the sliding ring air channel connection hole 7, but usually only two groups of lower branch flow channels can be directly connected to the sliding ring air channel connection hole 7, and other lower branch flow channels include the first flow channel 12, the second flow channel 13 and the third flow channel 14 connected in sequence, wherein the first flow channel 12 and the third flow channel 14 are arranged vertically, the second flow channel 13 is arranged horizontally, and the first flow channel 12 is located directly below the upper branch flow channel 10, and the two are connected to each other. Since the sliding ring has a plurality of air channels, it is necessary to open a plurality of lower branch flow channels on the inner side of the lower valve seat 2, which makes the internal space of the lower valve seat 2 more crowded. For this reason, the second flow channels 13 of each lower branch flow channel in this embodiment are arranged alternately in the height direction in the lower valve seat 2.

[0033] When working, the compressed air source is connected to the air supply channel 5 to uniformly supply air to all the solenoid valves. The solenoid valve realizes the opening and closing of each air distribution channel 4 according to the control of the controller to complete the air intake or exhaust. Since the air flow channels connecting the solenoid valve and the slip ring are respectively opened on the first valve seat and the second valve seat, the structure is simple and the processing is convenient. In addition, transverse air distribution channels 4 are opened on both sides of the upper valve seat 1. The air distribution channels 4 connect the solenoid valve air inlet and outlet holes 3 and the slip ring air channel. The solenoid valve air inlet and outlet holes 3 of the upper valve seat 1 are expanded to both sides, forming a larger space in the middle of the lower side of the lower valve seat 2, thereby avoiding the solid shaft inside the slip ring, and convenient installation.

[0034] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes.
