Description

Technical Field

[0001] The invention relates to the technical field of plastic packaging bottle production, and in particular to a bottle blowing device and method for producing cosmetic plastic packaging bottles. Background Art

[0002] A bottle blowing machine refers to a machine for blowing bottles. The most obvious explanation is that it is a machine that can blow plastic granules or finished bottle embryos into bottles through certain process means. In the production process of cosmetic plastic packaging bottles, plastic packaging bottles are generally processed by blowing bottles.

[0003] During use, the existing bottle blowing equipment for producing cosmetic plastic packaging bottles clamps the bottle mouth of the preform through two molding molds. When air is pressed into the bottle preform, the impact of the gas can easily cause the bottle mouth to fall from the two molding molds, posing a hidden danger of unstable clamping. At the same time, during the blow molding process, the bottle mouth of the preform does not need to be shaped, and a large amount of compressed gas introduced into this position can easily cause deformation of the bottle mouth, resulting in defects in the bottle mouth of the blow-molded packaging bottle, thereby reducing the use value of the bottle blowing equipment. Summary of the invention

5. A bottle blowing method for producing cosmetic plastic packaging bottles, using the bottle blowing equipment for producing cosmetic plastic packaging bottles according to claim 4, characterized in that: The following steps are involved: Step 1: After the preform is moved between the two mold bodies (2), the air cylinder 1 (11) is adjusted to drive the two mold bodies (2) to close, and then the hydraulic cylinder 1 (4) is adjusted to drive the sleeve frame (14) to move to the outside of the bottle mouth; Step 2: After adjusting the hydraulic cylinder 2 (12) to drive the blowing pipe (15) to descend to the specified position, the bottle mouth is fixed and the upper and lower ends of the bottle mouth are sealed through the sealing inner support component (16). After the sealing inner support is completed, the air compressor (8) is started. The air compressor (8) introduces compressed gas into the blowing pipe (15) and sprays it out through the blowing hole below the blowing pipe (15), and the blow molding process begins; Step 3: After the blow molding is completed, the cylinder 1 (11) drives the mold body (2) to reset. After the two mold bodies (2) are separated, if the formed packaging bottle is stuck in one of the mold bodies (2), the cylinder 2 (1813) is adjusted to drive the fitting plate (1801) to separate from the mold body (2), and the air pump (1805) is started. The air pump (1805) guides the condensed gas into the nozzle (1811), and sprays it through the gap between the fitting plate (1801) and the mold body (2) through the air jet hole (1810) to the formed packaging bottle. The cold gas cools it and blows it to achieve the packaging bottle unloading.
