New description: [New technical field] It refers to a kind of blowing bottle. This creation department is related to the blowing equipment, and the gas recovery device of the machine is more detailed. [Prior Art] According to the conventional blowing device for manufacturing a container by an extended blow molding method, the blowing pressure system and the operating pressure system use air pressure as a power source = the action of the second blowing, and the blowing system is mainly The air pressure (high gold air) is used to blow the preform, and the operating pressure system uses air pressure (low pressure air) to drive different mechanisms (such as the embryo mechanism, the bottle discharging mechanism, the preform conveying mechanism driven by the pneumatic cylinder and Extension agencies and other institutions). Since the air in the blow molding system and the operating pressure system is continuously consumed, the compressor must be operated frequently to continuously generate air with a predetermined relocation force, and consumes a lot of electricity. In order to solve these problems, as shown in the Patent Case No. 841, No. 7548 of the Republic of China, "Extension = Air Manipulation and Installation of Gas Forming Machine", the main characters are switching valves (solenoid valves) and check valves. The air circuit is connected to the air blowing circuit of the blowing mode=, the material shape~, and the air circuit is switched by the switching valve to use the human milk as part of the air-pressure recovery. Part. Although the technology disclosed in the previous patent can indeed solve the problem of power consumption caused by the frequent operation of the I shrinking machine of the stomach blowing equipment, the recovery system 5 M302467 f increases the operation time of the original blowing and exhausting two stages. In order to blow the bottle, recycle, and excavate -1 and the action time, although the energy saving effect can be achieved, the overall blowing time is prolonged, resulting in a decrease in the output of the machine. [New content] The main purpose of this creation is to provide a gas recovery device that can solve the bottle machine of the person who has previously lost the problem. The exhaust gas and the air recovery mechanism are synchronized, which can achieve energy saving effect without affecting the blowing bottle. Time. Lu Yuan is, in order to achieve the above objectives, the present invention provides a gas recovery device for a blow molding machine, which is a blowing pressure system connected to the blowing machine for using the air used for forming the preform. Recycling and transporting to the operating pressure system for utilization; characterized in that the gas recovery device comprises a recovery circuit connecting an exhaust control valve of the blow molding system and an intake circuit of the operating pressure system, and a pressure storage buffer a container disposed on the recovery line for storing and buffering the air recovered by the blowing pressure system, and a check valve connected to the recovery line so that the recovered air can only flow into the pressure storage buffer The reverse flow 'flow device' is not disposed on the side of the recovery line for allowing the recovery line to discharge an appropriate amount of air to control the amount of recovered air. [Embodiment] The following is a preferred embodiment of the present invention, and further detailed description with reference to the following: Referring to the first figure, the 6 M3 of the blow molding machine of the preferred embodiment is created. 02467 The gas recovery device 10 is connected to a blow molding system (not shown), a blow molding system 1 and an operation pressure secret 2, and includes a recovery pipeline 12 connected to the blow molding system 1 The air control valve 13 and the intake circuit 14 of the operating pressure system 2 can be used to convey all the air discharged from the exhaust control valve 13 to a pressure accumulating buffer 15, which is a solenoid valve. The accumulator buffer 15 is disposed in the middle of the recovery line 12, which is a gas tank that can accommodate air and buffer air pressure, and a check valve 16 is connected to the recovery line 12 and interposed between the exhaust control valve. 13 with a pressure buffer. Between the calls, the recovered air can only flow into the accumulator buffer 15 without reverse flow back to the 'one exhaust line 17, one end connected to the stomach side of the recovery line 12, the flow device 18, The throttle valve is disposed on the exhaust line 17 for allowing the recovery line 12 to discharge an appropriate amount of air to control the recovery of the air. In addition, the gas recovery device 10 further includes a muffler 19 connected to the end of the exhaust line 17. _ In this way, the operation of the gas recovery device 10 is as follows: When the blowing pressure system 1 completes the blowing operation of the preform, the exhaust control valve 13 is switched to the open state, and the blowing gas will be The discharge control valve 13 is discharged into the recovery line 12, and then flows into the accumulator buffer 15 to store and buffer the pressure (the recovery line 12 also has the effect of storing and relieving the gas pressure), In the operation (4), the mechanisms of the system 2 (the seeding mechanism 22 driven by the pneumatic cylinder, the bottle discharging mechanism 24, the preform conveying mechanism 26, the mold frame driving mechanism 28, and the extension mechanism 3, etc.) are activated. M3 02467 consumes the air of the air tank 32. At this time, the recovery pipeline 12 can transport the recovered empty milk to the intake circuit 14 of the operating pressure system 2 to compensate the air consumed by the air tank 32, such that In this way, the operating frequency of the compressor (not shown) can be reduced, and the running time can be shortened, thereby reducing the power consumption. Secondly, in order to avoid the air pressure accumulated in the recovery line 12, the recovered air can be discharged to the outside through the control of the exhaust line 丨7 and the throttle valve 18, and the damper can be silenced. The device l9 silences. As can be seen from the above, the gas recovery device of the blow molding machine provided by the present invention can recover all the blown gas discharged from the blow molding system 1 from the recovery line 12 and the accumulator buffer 15 and timely transport Up to the intake circuit 14 of the operating pressure system 2, the operation rate of the compressor can be greatly reduced to improve the energy saving effect, and the creation is not only the exhaust gas and the recovered gas, compared with the gas recovery device of the conventional blow molding machine. The action system is carried out simultaneously, which can achieve energy-saving effect without affecting the blowing time; the reason is that the creation does comply with the requirements of the new patent, and the application is made according to law.
