Abstract

The invention relates to double-side bottle blowing equipment, and relates to the field of bottle blowing equipment. The double-side bottle blowing equipment is used for blowing air to the two sides of a partition plate in a bottle body, and comprises a rack, a conveying device and a forming device, wherein the conveying device and the forming device are arranged on the rack; the conveying device comprises a plurality of conveying seats and a conveying portion used for conveying the conveying seats to the forming device one by one; through holes are vertically formed in the conveying seats; the forming device comprises two molds arranged on the two sides of the conveying direction of the conveying seats, a driving assembly used for driving the two molds to be close to or away from each other, and a high-pressure air blowing assembly located below the conveying seats; the high-pressure air blowing assembly comprises an air source, an air blowing piece and air blowing nozzles; the air blowing piece is used for blowing high-pressure air in the air source out of the air blowing nozzles; and the two air blowing nozzles are arranged, are used for being arranged in the through holes in a penetrating mode, and are used for blowing air to the two sides of the partition plate in the bottle body. The double-side bottle blowing equipment has the effect of avoiding leakage on the two sides of the partition plate of the plastic bottle.

Description

technical field [0001] The present application relates to the field of bottle blowing equipment, in particular to a double-sided bottle blowing equipment. Background technique [0002] Existing a plastic bottle, such as figure 1 As shown, the cross-section of the bottle body is elliptical, and one end of the bottle body is open. A partition is fixed inside the short diameter of the bottle body. The length direction of the partition is the same as that of the bottle body, and the height of the partition is the same as that of the bottle body. , The partition divides the inside of the bottle into two chambers. [0003] The current molding process of the above-mentioned plastic bottle is to firstly blow mold the preform with a circular cross-section by blow molding equipment to form a bottle body with an oval cross-section, and then fix the partition in the bottle body. In this molding method, since the partition is fixed to the bottle body after the bottle body is formed, it...
