The working principle of the invention is as follows:

when the bottle opener is used, different die sets 24 are selected according to different bottle sizes, the process is as follows, the driving motor II 26 drives the belt type transmission piece II 28 to rotate, different die sets 24 are moved to be under the welding square plate 25, then the electric telescopic rod II 45 drives the electromagnet 47 to descend and contact with the magnet 34, the electromagnet 47 is started to carry out magnetic adsorption on the magnet 34, at the moment, the electric telescopic rod III 48 drives the lower pressing plate 50 to descend to extrude the square sliding block 41 downwards through the lower pressing block 44, at the moment, the square sliding block 41 compresses the elasticity sleeved outside the vertical rod 40, the vertical rack 42 drives the gear II 43 to rotate when moving downwards, further drives the screw rod 37 to rotate, under the transmission action of the screw rod 37 and the movable plate 36, the positioning rod 39 is retracted from the positioning hole 21 on the sliding seat 30, the die sets 24 are taken down from the two sliding seats 30, then the electric telescopic rod II 45 continues to extend, the mold seat 33 enters the interior of the mold placing cavity 22, then the electric telescopic rod III 48 rises to relieve the downward pressure on the vertical rack 42, under the reset action of the spring, the positioning rod 39 enters the interior of the positioning hole 21 on the mold mounting seat 17 to be clamped, the installation of the mold is completed, and similarly, the mold inside the mold placing cavity 22 can be switched, a plurality of mold groups 24 are preset on the mold storage structure 5, the corresponding mold groups 24 can be switched according to different bottle blowing requirements, the improvement of the adaptability of a bottle blowing system is facilitated, the structure is more optimized, and the design is more reasonable;

the rotating plate 57 is pulled upwards to take the bottleneck positioning block 56 down from the object carrying plate 51, otherwise, the connecting ring 53 enters the connecting groove 54, the limiting groove 61 and the limiting convex rod 62 are clamped, the bottleneck positioning block 56 can be installed, the bottleneck positioning block 56 can be switched, the bottleneck positioning block 56 can be replaced by the mold group 24 which is used at present, the bottleneck positioning block 56 which is matched with the mold group 24 can be replaced, the stability of bottle blank installation is ensured, the transformation of the whole system can realize the replacement of different bottles for bottle blowing operation only by switching the mold group 24 and the bottleneck positioning block 56, and the method is simple, rapid and very convenient;

after the bottle blank is inversely installed on the bottle opening positioning block 56, the driving motor I12 drives the transmission shaft 9 to rotate through the belt type transmission piece I11, so that the transmission shaft 9 drives the material carrying structure 10 to rotate, the bottle blank is moved, after the bottle blank enters the heating bin 3, the bottle blank is heated through the heating rod 15, the transverse rack 14 and the gear I60 are in meshing transmission, so that the rotating plate 57 rotates, the bottle blank is heated and rotates, the bottle blank is heated more comprehensively and uniformly, the precision is high, the heating effect is good, and the subsequent blank blowing operation is facilitated;

after the bottle blank is heated and when the bottle blank is positioned between the two mold placing cavities 22, the two electric telescopic rods 18 extend simultaneously to enable the bottle blank to be positioned in the cavity formed by the two mold seats 33, then the electric telescopic rods 67 extend to enable the electric telescopic rods 67 to be inserted into the air holes 52, then the bottle blank is blown up through the air pump 66 in the bottle blank, the bottle blowing operation is completed, and the related structure resets after the bottle blowing is completed to wait for the next bottle blowing.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
