Blow molding machine with air conditioning

Abstract

A blow molding machine with air conditioning that while minimizing the introduction rate of outside air, realizes maintaining of constant temperature in not only a plant building but also the interior of a blow molding machine and production of a bottle as a final configuration with stability in its measurement value. The blow molding machine with air conditioning is constructed so that air for use in biaxially stretching blow molding together with hot air of heating zone (1) and internal air of a plant building is suctioned by means of suction chamber (4), filtered by means of primary filer (6) and secondary filter (7) into clean air, brought into heat exchange with primary cooling coil (8), fed under pressure by air blower (10) and released through low-temperature duct (12) into the interior of the plant building. Further, the construction is made so that housing (3) on its side face is provided with vent (3a) so as to allow reflux of the clean air released into the interior of the plant building and flow into the heating zone (1) and blow zone (2).

Description

technical field [0001] The present invention relates to an air-conditioned blow molding machine, and more particularly to a machine capable of suppressing the intake of external air to a minimum and keeping An air-conditioned blow molding machine that maintains a constant temperature in the factory building and inside the blow molding machine to stabilize the measured value of the bottle as the final shape. Background technique [0002] Conventionally, in factories such as food processing factories and food container manufacturing factories, in order to prevent the inside of the factory buildings from being contaminated by bacteria from the outside, the air pressure inside the factory buildings was set higher than the outside air pressure to positively pressurize. Therefore, when introducing outside air (air outside the factory building) into the factory building, it is introduced after filtering the air through a filter or the like to remove bacteria and the like as much as...

AI Technical Summary

Problems solved by technology

[0010] As mentioned above, when the temperature inside the factory building is kept constant by introducing outside air, a filter and an air conditioner with a large filtering area are required, and there is a problem of an increase in cost related to this.

[0011] In addition, in the air conditioner of the above-mentioned injection stretch blow molding machine, only the dehumidification of the injection molding station is performed, and the blow molding station for stretch blow molding is not air-conditioned. The problem of changes in the measurement value of the bottle still exists
