DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0021] A preform taking mechanism of a four-in-one injection-blowing-filling-sealing machine comprises a base 1, an electric telescopic rod A11 is fixedly installed at the center of the upper surface of the base 1, a carrier plate 2 is fixedly installed at the top of the electric telescopic rod A11, a carrier 3 and a vacuum box 4 are fixedly installed on the upper surface of the carrier plate 2, the number of the carriers 3 is N, and N is an integer, a metal air guide tube 5 is fixedly installed in each of the carriers 3, a sterile air bag 51 is fixedly installed at the exhaust end of the metal air guide tube 5, an air supply tube 52 is installed between the air inlet end of the metal air guide tube 5 and the inner cavity of the vacuum box 4, an electric telescopic rod B41 is embedded and fixedly installed on the rear surface of the vacuum box 4, a push plate 42 is fixedly installed on the front end of the electric telescopic rod B41, a rubber sealing pad 421 is fixedly installed on the front surface of the push plate 42, and the outer surface of the rubber sealing pad 421 is in contact with the inner wall of the vacuum box 4;

[0022] When installing the preform taking mechanism, the metal air guide tube 5 needs to be set just above the preform. When taking the preform out of the mold, the electric telescopic rod A11 is used to drive the carrier plate 2 and the carrier 3 to move downward. During the downward movement of the carrier 3, the metal air guide tube 5 and the sterile air bag 51 are driven to extend into the preform. Then, the electric telescopic rod B41 is extended to drive the push plate 42 and the rubber sealing pad 421 to move to the left. During the movement of the rubber sealing pad 421, the gas in the vacuum box 4 is discharged into the sterile air bag 51 through the air supply pipe 52 and the metal air guide tube 5. The sterile air bag 51 is expanded inside the preform, thereby clamping the preform from the inside. After clamping, the electric telescopic rod A11 is used to drive the carrier plate 2 and the carrier 3 to move upward to remove the preform from the mold. When the preform is put down, the electric telescopic rod B41 is extended to drive the push plate 42 and the rubber sealing pad 421 to move to the right side, and the gas in the sterile air bag 51 is extracted, so that the sterile air bag 51 is deflated. At this time, the metal air guide tube 5 and the sterile air bag 51 can be taken out from the preform. The preform taking structure is simple in structure and can be suitable for taking preforms of different models.

[0023] like Figure 4 As shown, a slide groove 21 is provided on the upper surface of the carrier plate 2, and a slide rod 32 is fixedly installed on the lower surface of the carrier 3. The slide rod 32 is slidably set in the slide groove 21, and a thread is provided on the outer surface of the bottom end of the slide rod 32. Nuts 33 are screwed and installed at the threads of the slide rod 32. The upper surface of the nut 33 is in contact with the lower surface of the carrier plate 2, and the lower surface of the carrier 3 is in contact with the upper surface of the carrier plate 2. In actual use, the nut 33 can be loosened to adjust the distance between two adjacent carriers 3 so as to adapt to the use of bottle embryo molds with different spacings.

[0024] To further facilitate the adjustment of the distance between the carriers 3, as Figure 4 As shown, a distance scale mark 22 is engraved on the front surface of the carrier plate 2, and the distance of the carrier 3 can be accurately adjusted according to the distance scale mark 22 during adjustment.

[0025] Specifically, the front end of the carrier 3 is penetrated with an installation opening 31, and the metal air guide tube 5 is inserted into the installation opening 31. The front surface of the carrier 3 is penetrated with a tightening bolt 311 threadedly installed. After the rear surface of the tightening bolt 311 is fitted with the outer surface of the corresponding metal air guide tube 5, the metal air guide tube 5 is fixed in the installation opening 31. The metal air guide tube 5 can be a tube made of iron, copper or alloy, and the metal air guide tube 5 is clamped in the installation opening 31 of the carrier 3 by the tightening bolt 311.

[0026] Finally, in order to make the carrier plate 2 move up and down more smoothly, as shown in FIG. Figure 1As shown, four guide rods 12 are fixedly mounted on the upper surface of the base 1. After the carrier plate 2 is slid up and down and set between the four guide rods 12, the guide rods 12 can be used to limit the carrier plate 2 circumferentially so that it can move up and down more smoothly.
