[0044] Working principle: First, move the main body 4 of the automatic air-supply device for the blow molding machine to the insert block 2 and insert it into the slide groove 3, so that the main body 4 of the automatic air-supply device for the blow molding machine can be connected to the bottom plate 1.

Then pass the limit button 902 through the block 901 and connect it with the internal thread of the limit hole 16. At this time, the insert plate 903 can be limited, and then move the bottom plate 1 to the position where the automatic air-supply device body 4 of the blow molding machine needs to be installed, and use the external bolts to pass through. Install the block 11, and thread the external bolts to the installation position to install the bottom plate 1 and the body 4 of the automatic air-filling device for the blow molding machine in place. When the body 4 of the automatic air-filling device for the blow molding machine is working, the fan 6 is controlled to work.

The bottom of the body 4 of the automatic air-filling device for the blow molding machine will take away the heat through the air flow inside the heat dissipation groove 14, and the aluminum bottom plate 1 will absorb the heat of the body 4 of the automatic air-filling device for the blow molding machine and transfer it to a larger area. The installation position is used to assist in heat dissipation, so that the main body 4 of the automatic air-filling device of the blow molding machine is always in the best working state. When the main body 4 of the automatic air-filling device of the blow molding machine needs to be disassembled and repaired, it is only necessary to twist the two limit buttons 902 to disengage the limit buttons 902 from the limit holes 16, and then the plug plate 903 can be pulled out of the plug hole 15, and then the pull ring 12 can be pulled out of the main body 4 of the automatic air-filling device of the blow molding machine from the top of the bottom plate 1, so that the main body 4 of the automatic air-filling device of the blow molding machine can be easily repaired. When installing again, insert the plug block 2 into the slide groove 3, insert the plug plate 903 into the bottom plate 1, lock the two limit buttons 902, and the blow molding machine can be installed without the help of The automatic air supply device body 4 of the blow molding machine can be disassembled and reinstalled without tools, which saves time and effort, improves the efficiency of the maintenance of the automatic air supply device body 4 of the blow molding machine, and avoids the need for more external bolts when installing the automatic air supply device in most existing PE film blow molding machines. When the automatic air supply device is disassembled and repaired, more external bolts need to be disassembled again, affecting the efficiency of disassembly and reinstallation, thereby affecting the maintenance efficiency of the automatic air supply device, and after the internal valve of the automatic air supply device is rotated many times, heat will be generated, which is inconvenient to dissipate quickly, which is easy to affect the normal operation of the automatic air supply device.
