[0022] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0023] Please refer to Figures 1 to 5 As shown, a bottle blowing device with integrated sealing valve comprises a triple solenoid valve assembly and a sealing assembly, wherein one side of the sealing assembly is connected to one side of the triple solenoid valve assembly;

[0024] The triple solenoid valve assembly comprises a high-pressure gas distribution block, a triple high-pressure valve body, a first solenoid valve assembly, a second solenoid valve assembly and a third solenoid valve assembly. The first solenoid valve assembly, the second solenoid valve assembly and the third solenoid valve assembly have the same structure. The high-pressure gas distribution block is provided with a first air inlet and a first exhaust port. The triple high-pressure valve body is arranged on the high-pressure gas distribution block. The first solenoid valve assembly, the second solenoid valve assembly and the third solenoid valve assembly are respectively arranged on the triple high-pressure valve body. The first solenoid valve assembly is used to control the output of high-pressure gas to the sealing assembly. The second solenoid valve assembly is used to control the recovery of high-pressure gas. The third solenoid valve assembly is used to control the discharge of high-pressure gas.

[0025] The first solenoid valve assembly includes a solenoid valve switch, a cylinder body and a piston. The cylinder body is provided with a second air inlet and a second air outlet. The solenoid valve switch is arranged on the cylinder body and is used to control the air inlet and outlet of the cylinder body. The cylinder body is arranged on the triple high-pressure valve body. The piston is arranged between the cylinder body and the triple high-pressure valve body, and the piston forms two pressure air chambers with the cylinder body and the triple high-pressure valve body respectively.

[0026] The principle of the present invention is as follows: the solenoid valve switch controls the closing or opening of the solenoid valve by controlling whether the gas pressure in the pressure air chamber on the upper part of the piston is greater than the pressure air chamber on the lower part of the piston. Before bottle blowing begins, the mouth of the bottle embryo is sealed with a sealing assembly, and then high-pressure gas is blown into the bottle from the first air inlet. In the initial state, the solenoid valve switch is in a closed state, and the gas pressure in the pressure air chamber on the upper part of the piston is greater than the pressure air chamber on the lower part of the piston. The solenoid valve switch is turned on to discharge the gas in the pressure air chamber on the upper part of the piston of each solenoid valve assembly (referring to the first, second and third solenoid valve assemblies) from the second exhaust port, and the gas pressure in the pressure air chamber on the lower part of the piston is greater than the pressure air chamber on the upper part of the piston. The gas pressure in the pressure air chamber is increased, and the piston moves upward so that the high-pressure gas is not restricted by the piston. At this time, the first solenoid valve assembly delivers the high-pressure gas to the sealing assembly to blow and shape the bottle embryo. After the bottle embryo is molded, the solenoid valve switch is closed, and the second solenoid valve assembly recovers the remaining high-pressure gas from the second air inlet of the exhaust cylinder of each solenoid valve assembly to the pressure air chamber on the upper part of the piston for reuse, so that the gas pressure in the pressure air chamber on the upper part of the piston is greater than the gas pressure in the pressure air chamber on the lower part of the piston. The piston moves downward to close the solenoid valve, and finally the third solenoid valve assembly discharges the remaining high-pressure gas from the first exhaust port, thereby completing the blowing and shaping of the bottle embryo.

[0027] From the above description, it can be seen that the beneficial effects of the present invention are: by directly connecting the triple solenoid valve assembly and the sealing assembly together to form an integral body, no additional pipe fittings are required to connect the two, thereby reducing the equipment volume and equipment cost, and greatly reducing the volume of gas circulating between the triple solenoid valve assembly and the sealing assembly, reducing gas waste, and improving energy saving effects. In addition, the gas can be recycled and reused, so that the gas can be used sustainably, further improving the energy saving effect.

[0028] Furthermore, the shape of the piston is T-shaped, and the top surface area of ​​the piston is larger than the bottom surface area.

[0029] From the above description, it can be seen that since the pressure formula is: pressure = pressure * area, by setting the shape of the piston to be T-shaped, the top surface area of ​​the piston is larger than the bottom surface area, and the pressure air cavity in the lower half of the piston is introduced with high-pressure gas for blow molding of the bottle embryo. By adding an appropriate amount of low-pressure gas to the pressure air cavity in the upper half of the piston, the gas pressure of the pressure air cavity in the upper half of the piston can be greater than the gas pressure of the pressure air cavity in the lower half of the piston (that is, the low-pressure gas pressure in the upper half of the piston * the top surface area of ​​the piston > the high-pressure gas pressure in the upper half of the piston * the bottom surface area of ​​the piston), and then by controlling the extraction and discharge of the low-pressure gas in the pressure air cavity in the upper half of the piston, the up and down movement of the piston can be controlled at high speed, thereby improving the control efficiency.

[0030] Furthermore, the first solenoid valve assembly also includes a fixing ring, the fixing ring is adapted to the piston, and the fixing ring is arranged below the piston.

[0031] It can be seen from the above description that by arranging a fixing ring under the piston, the stability of the piston movement can be improved.

[0032] Furthermore, the first solenoid valve assembly also includes a first sealing ring, and the first sealing ring is arranged at the connection between the piston and the fixing ring.

[0033] It can be seen from the above description that providing a first sealing ring at the connection between the piston and the fixing ring can improve the sealing performance when the piston moves.

[0034] Furthermore, the triple solenoid valve assembly also includes a muffler, and the muffler is arranged on the first exhaust port.

[0035] From the above description, it can be seen that since the high-pressure gas will produce a loud noise when discharged from the first port, thereby causing noise pollution, a muffler is provided on the first exhaust port, which can greatly reduce the sound of the high-pressure gas being discharged, thereby greatly reducing noise pollution.

[0036] Furthermore, the triple solenoid valve assembly also includes a valve sealing connection block, and the valve sealing connection block is arranged between the triple solenoid valve assembly and the sealing assembly.

[0037] It can be seen from the above description that by providing a sealing valve connecting block between the triple solenoid valve assembly and the sealing assembly, the connection between the triple solenoid valve assembly and the sealing assembly can be made more stable.

[0038] Furthermore, it also includes a pre-blowing assembly, one side of which is connected to the other side of the sealing assembly;

[0039] The pre-blowing assembly comprises a fourth solenoid valve assembly, a pre-blowing connection seat and a control assembly. The fourth solenoid valve assembly has the same structure as the first solenoid valve assembly. The fourth solenoid valve assembly is arranged on the pre-blowing connection seat, and the control assembly is arranged on the other side of the pre-blowing assembly.

[0040] The control component includes a throttling shaft and a throttling plug, one end of the throttling plug is arranged inside the other side of the pre-blowing connecting seat, and the other end of the throttling plug is arranged outside the other side of the pre-blowing connecting seat and connected to one end of the throttling shaft, one end of the throttling shaft can drive the throttling plug to rotate on the pre-blowing connecting seat, and when rotating, one end of the throttling plug can move between the two sides of the pre-blowing connecting seat.

[0041] From the above description, it can be known that before the sealing group introduces high-pressure gas to perform high-pressure blowing on the preform, the pre-blowing component is first used to introduce low-pressure gas into the sealing group to pre-blow the preform, so as to prevent the preform from being "suddenly" subjected to high-pressure blowing and causing damage to the preform. The throttling shaft is rotated to control the throttling plug to extend and retract in the pre-blowing connecting seat to control the flow rate of the low-pressure gas, and the operation is simple and convenient.

[0042] Furthermore, the control component also includes a shaft fixing block, which is arranged on the other side of the pre-blowing component, and one end of the throttling shaft passes through the shaft fixing block and is rotatably connected to the pre-blowing component.

[0043] It can be seen from the above description that by providing the rotating shaft fixing block, the rotating shaft can rotate more stably, thereby increasing stability.

[0044] Furthermore, the control component also includes a position display, which is arranged on the shaft fixing block, and one end of the throttling shaft passes through the position display and the shaft fixing block in sequence and is connected to the other end of the throttling plug.

[0045] From the above description, it can be known that by arranging a position indicator on the shaft fixing block, the rotation of the throttling shaft can be controlled more accurately, thereby accurately controlling the flow rate of the gas and improving the precision of the device.

[0046] Furthermore, it also includes a second sealing ring and a third sealing ring, the second sealing ring is arranged at the connection between the throttling shaft and the throttling plug, and the third sealing ring is arranged at the connection between the throttling shaft and the shaft fixing block.

[0047] It can be seen from the above description that, by providing the second sealing ring and the third sealing ring, the sealing performance between the throttling shaft, the throttling plug and the shaft fixing block is improved, gas loss is reduced, and thus gas costs are saved.
