The front end of the third electric telescopic rod 22 extends to the front side of the back plate 21 and is fixedly connected to a side cutter 23.

[0032] After the blow molding tube 17 carries the blank, it heats and softens the blank. After softening, the moving table 16 moves the blank to the corresponding position of the mold mechanism, and then the mold mechanism and the air pump mechanism work to blow mold the blank.

[0033] After processing, the moving table 16 moves the cosmetic packaging bottle to the corresponding position of the side cutter 23 and the bottle mouth cutter 30. Then, the fourth electric telescopic rod 29 drives the bottle mouth cutter 30 to contact the bottom of the bottle mouth. Then, the third electric telescopic rod 22 extends, driving the side cutter 23 to contact the side of the bottle mouth. Finally, the blow molding tube 17 rotates to cut off the waste material on the bottle mouth.

[0034] The cutting operation is simple and quick, reducing the workload of staff and improving the production and processing efficiency of cosmetic packaging bottles.

[0035] After the moving table 16 rotates, its top surface can be tilted to dump the waste material remaining on its surface, keeping the surface of the moving table 16 clean. This is beneficial for the subsequent production of cosmetic packaging bottles, improves the quality of the finished cosmetic packaging bottles, and increases the production qualification rate of cosmetic packaging bottles.

[0043] In this embodiment, after the moving platform 16 moves the blow molding tube 17 between the two upper molds 20, the second electric telescopic rod 19 can extend to bring the two upper molds 20 closer to each other. After the two upper molds 20 are spliced ​​together to form a mold, the air pump mechanism works to inject airflow into the blow molding tube 17 to perform blow molding.

[0044] Furthermore, the air pump mechanism includes a first electric telescopic rod 3, an air inlet 37, an air pump body 4, and a connector 6. The first electric telescopic rod 3 is vertically fixed to the bottom of the inner wall of the housing 2, the air pump body 4 is fixedly connected to the top of the first electric telescopic rod 3, the air inlet 37 is opened on the side wall of the housing 2, the connector 6 is vertically connected to the air outlet of the air pump body 4, and the bottom of the moving platform 16 is provided with an air inlet 27 adapted to the connector 6.

[0045] In this embodiment, the first electric telescopic rod 3 extends and drives the top end of the insertion tube 6 to be inserted into the air inlet 27.

The air inlet of the dust collection fan 10 is connected to an air inlet pipe 5, and the other end of the air inlet pipe 5 is connected to the dust collection tray 33.

[0049] In this embodiment, when the dust extraction fan 10 is working, it can draw airflow from inside the dust extraction disk 33 through the air inlet pipe 5, thereby creating negative pressure inside the dust extraction disk 33, which can then extract and remove the dust generated during the cutting process, thus preventing the dust from affecting the surrounding environment.

[0050] Furthermore, the exhaust pipe of the vacuum fan 10 extends into the inner cavity of the dust collection box 34, and a dust removal bag 7 is detachably installed therein. An exhaust window 35 is provided at the bottom of the dust collection box 34, and an inspection door is detachably installed on the side wall of the dust collection box 34.

[0051] In this embodiment, the dust drawn by the vacuum fan 10 is discharged into the interior of the dust collector bag 7. After the dust collector bag 7 collects the dust in the airflow, the airflow is discharged through the exhaust window 35.

[0052] The working principle and usage process of this invention: After the invention is installed, the blow molding tube 17 carries the preform and heats and softens it. After softening, the moving table 16 moves the preform to the corresponding position of the mold mechanism. Then, the mold mechanism and the air pump mechanism work to blow mold the preform. After processing, the moving table 16 moves the cosmetic packaging bottle to the corresponding position of the side cutter 23 and the bottle mouth cutter 30. Then, the fourth electric telescopic rod 29 drives the bottle mouth cutter 30 to contact the bottom end of the bottle mouth. Then, the third electric telescopic rod 22 extends and drives the side cutter 23 to contact the side of the bottle mouth. By rotating the blow molding tube 17, the waste on the bottle mouth can be cut off, improving the production efficiency of cosmetic packaging bottles. After the moving table 16 rotates, the top surface of the moving table 16 can be tilted to dump the waste remaining on the surface of the moving table 16, keeping the upper surface of the moving table 16 clean, which is beneficial to the subsequent production of cosmetic packaging bottles.
