Embodiment Construction

[0020] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] see figure 2 As shown, the compensation air path of the above-mentioned blow molding machine uses the sealing cylinder 1 that moves up and down to seal the preform and then blows it. The preform is located in the mold 2. The sealing cylinder 1 includes an air inlet valve and an exhaust valve. valve.

[0022] The compensation gas circuit of the bottle blowing machine includes a gas output device, a blowing gas pipeline for blowing the preform, and a compensation gas pipeline for blowing the mold 2. The blowing gas pipeline and the compensation gas pipeline are both It is connected to the exhaust valve, and the blowing gas pipeline and the compensation gas pipeline are simultaneously fed into the blowing gas pipeline through the exhaust valve.

[0023] The gas output device includes a first blowing pipeline 3 for outputting a f...

Abstract

The invention discloses a complemental air circuit for a bottle blowing machine. Air is blown into a bottle blank through a sealing cylinder; the bottle blank is located in a mold; the sealing cylinder comprises an air inlet valve and an air release valve; the complemental air circuit for the bottle blowing machine comprises a gas output device, a bottle blowing air pipeline and a complemental air pipeline; the bottle blowing air pipeline is used for blowing air into the bottle blank; the complemental air pipeline is used for blowing air into the mold; both the bottle blowing air pipeline and the complemental air pipeline are connected onto the air release valve; the gas output device comprises a first air blowing pipeline and a second air blowing pipeline; the first air blowing pipeline is used for outputting the first circuit of high-pressure gas and the second air blowing pipeline is used for outputting the second circuit of high-pressure gas; and both the first air blowing pipeline and the second air blowing pipeline are connected onto the air inlet valve. According to the complemental air circuit for the bottle blowing machine, both the bottle blowing air pipeline used for blowing the bottle blank and the complemental air pipeline used for compensating the mold are connected to the air release valve of the sealing cylinder; and air is supplied to the bottle blowing air pipeline and the complemental air pipeline alternately through the first air blowing pipeline and the second air blowing pipeline which are connected onto the air inlet valve of the sealing cylinder, so that an air circuit system of the bottle blowing machine is simplified, and the cost is reduced.

Description

technical field [0001] The invention relates to a compensation gas path of a bottle blowing machine. Background technique [0002] When the bottle blowing machine blows the bottle, because the cavity of the mold is filled with high-pressure air, the mold must be pushed outward, which will cause the joint to become larger and affect the quality of the blown bottle. Therefore, the compensation gas is connected to the outside of the mold to compensate the pressure in the mold cavity and eliminate its influence on the mold clamping gap, thereby improving the quality of the blown bottle. [0003] traditional methods such as figure 1 As shown, the compensation gas is connected from the second blowing pipeline 4, connected to the compensation ring pipe through the compensation air pipe, and then connected to the compensation valve 8 through the compensation ring pipe, and connected to the mold base through the compensation valve 8 to output to the mold 2 Compensation gas.
