Description

Technical Field

[0001] The invention relates to the technical field of glass bottle processing, in particular to a glass bottle processing blow molding process. Background Art

[0002] Glass bottles are a type of transparent product widely used as packaging containers with a long history and diverse uses. The main features of glass bottles include high transparency, easy cleaning, good chemical stability, no pollution to contents, high air tightness, and excellent storage performance. They can be sealed with lids or stoppers to quantitatively hold various materials, such as beverages, alcoholic beverages, chemicals, medicines, educational supplies, and cosmetics. In the glass bottle processing process, the glass bottles are usually blow molded by the pressure-blowing method.

[0003] As disclosed in a Chinese patent: A glass bottle extrusion molding machine capable of reducing defective products, application number: CN202322087281.6, including a mechanical base, a horizontal movable pair, a motion mechanism, a vertical movable pair, a fixed bracket, a blowing device, a mold and an upper mold, etc.; the mold is slidably connected to the middle of the upper part of the mechanical base, the upper mold is connected to the mechanical base, and the upper mold is directly above the mold, the upper part of the mechanical base is slidably connected to the horizontal movable pair, the upper part of the horizontal movable pair is connected to the motion mechanism, the left side of the horizontal movable pair is connected to the vertical movable pair, and the front part of the vertical movable pair is slidably connected to the fixed bracket, and the gear and the rack are driven to move by a rotating motor, thereby driving the reciprocating motion of the horizontal movable pair, so that the air outlet of the blowing device and the blowing mold port can be on the same horizontal plane.

[0004] However, in the above technical solution, when the glass bottle needs to be blow-molded, it is necessary to insert the blow tube into the bottle embryo, and then use the blow tube to send compressed air into the bottle embryo to make the bottle embryo gradually larger for blow molding. However, during the molding process, the bottom of the glass bottle will gradually move away from the air outlet of the blow tube, causing a huge change in the distance between the air outlet of the blow tube and the bottom of the glass bottle, resulting in uneven distribution of the blow molding air pressure on the bottle bottom due to the change in distance, increasing the probability of uneven thickness of the bottle bottom. Summary of the invention
