The bottle embryo bottle mouth blowing device of the bottle blowing machine relates to the technical field of bottle blowing machine auxiliary equipment. The adjusting mechanism is arranged to adjust the bottle embryo of different specifications and sizes to ensure the cooling effect.

[0040] However, the bottle embryo bottle mouth blowing device has only a single station, and cannot perform blowing and cooling operations on multiple bottle mouthes, which is difficult to meet the production needs of factory assembly lines, and the structure needs to be improved.

[0041] In order to solve the technical problems existing in the bottle preform bottle mouth blowing device in the prior art, such as Figure 1 and Figure 2 The utility model provides a bottle blowing mechanism, including base 1 and the work station tray 2 of installing on base 1.

[0043] As shown in Figure 3 The bottle blowing mechanism further comprises a blowing nozzle 4 and a blowing conduit 5.

[0044] The blowing nozzle 4 is fixedly installed in the blowing hole 3 and has a gas guide hole at the top end; preferably, the blowing nozzle 4 is detachably fixedly installed in the blowing hole 3.

[0045] As shown in Figure 3 One end of the blowing conduit 5 is fixedly installed on the blowing nozzle 4 and communicates with the gas guide hole, and the other end is in the shape of a horn mouth. Preferably, the side wall of the gas guide hole is provided with a rubber sealing layer, and one end of the blowing conduit 5 is inserted into the gas guide hole and tightly contacts the rubber sealing layer after penetrating the rubber sealing layer. In this way, by providing the rubber sealing layer, the blowing conduit 5 can be fixedly installed and replaced.

[0046] The other end of the blowing conduit 5 is in the shape of a horn mouth, which is inserted into the bottle preform and close to the bottom of the bottle preform when the bottle blowing mechanism is working. That is, the bottle preform product to be blown and cooled is inverted on the work station tray 2 with the bottom of the bottle preform facing upwards. Since the other end of the blowing conduit 5 is in the shape of a horn mouth, the blowing gas flow can flow uniformly to all directions through the other end of the blowing conduit 5, and the bottom and the surrounding sidewall of the bottle preform can be blown and cooled, so that the whole bottle preform can be uniformly cooled and cooled down.

[0047] In summary, the bottle blowing mechanism can blow and cool multiple bottle preforms by providing multiple blowing holes 3 uniformly distributed along the circumference on the work station tray 2 and providing blowing nozzles 4 on the blowing holes 3, which can well meet the needs of factory assembly line production and solve the problem that the existing bottle preform bottle mouth blowing device has only a single station and cannot blow and cool multiple bottle preform bottle mouths, which is difficult to meet the needs of factory assembly line production, and has good practicability.

[0048] In addition, by providing the blowing conduit 5 and the other end of the blowing conduit 5 in the shape of a horn mouth, the gas flow can be uniformly dispersed and blown to all directions, so that the blowing and cooling gas flow can flow along the surrounding of the bottle preform to uniformly cool and cool down the whole bottle preform.

[0055] Specifically, the air outlet pipe 9 and the air inlet pipe 8 are diagonally arranged, so that the air entering from the air inlet pipe 8 can be fully flowed through the cooling water pipe 7 and effectively cooled, and then flowed out from the air outlet pipe 9, and then sequentially flowed into the bottle embryo product through the air blowing nozzle 4 and the air blowing guide pipe 5, so as to cool the bottle embryo product as a whole.

[0056] As a preferred technical solution, the side wall of the air blowing nozzle 4 is provided with a plurality of exhaust holes 12.

[0057] By arranging a plurality of exhaust holes 12, after the bottle embryo product is cooled and cooled by the cooling air, the airflow can be transported to the air through the exhaust holes 12 to accelerate the cooling effect of the bottle embryo product.
