Description
Technical field
The present invention relates to a kind of efficient blow-forming facility of hollow container and technique.
Background technology
The hollow container (such as bottle, bucket) of extrusion blow is typically blown with 8bar compressed airs, and mold design has water channel, is passed through cold
Freeze water, take away heat, make plasthetics shaping perfect in mould water channel design comparison, blow air pressure, freeze hydraulic pressure/water temperature
Under normal circumstances, in order to improve the manufacturing cycle, have producer both at home and abroad and use in subzero 25 degree of 8bar compressed airs blowing
Empty container, and using interruption blowing method (one, which blows a row, takes away heat, such as blows 3S, arranges 0.5S), facts have proved effectively
Shorten and be manufactured the cycle up to 15% or so.
But current cold air blowing hollow container technology has the following disadvantages.
It is real as a result of interruption blowing method (one, which blows a row, takes away heat), subzero 25 degree of 8bar compressed airs
May there was only 6bar pressure in the container blown on border, the heat that mould chilled water is taken away can be influenceed, can also influence to make in addition
Some mark definition on product surface.
With subzero 25 degree of compressed air blown container, the blow needle of prior art, can only ensure container blowing mouth that
Portion of gas flows, one, which blows a row, takes away heat, and container bottom or remotely, and interruption blowing effect is limited.
The content of the invention
The present invention seeks to：A kind of efficient blow-forming facility of hollow container and technique are provided.
In order to solve the above-mentioned technical problem, a kind of technical scheme for using of the present invention is：
A kind of efficient blow-forming facility of hollow container, including for the source of the gas preparation device for manufacturing low temperature compressed air and the gas
The blowning installation and exhaust apparatus that source preparation device is connected, the blowning installation includes blow needle, blow needle centre is provided with
The blow needle central tube that can be twitched up and down.
Further：1-3mm gaps are provided between the blow needle central tube and the blow needle.
Further：The source of the gas preparation device includes being used for by the booster pump of Ordinary Compression supercharging air and via cooling
The air conditioner that device is connected with the booster pump.
Further：The blow needle central tube is connected by heat-preserving hose with the air conditioner, and the blow needle center
Pipe is connected with sensor and valve by heat-preserving hose.
Further：The blow needle central tube is driven by the cylinder.
Further：The exhaust apparatus includes the exhaust shutter that the blow needle is provided with.
The efficient technological process for blowing of hollow container of the present invention, including have the following steps：
1）Low temperature compression source of the gas prepares；
2）Low temperature compressed air, which is continuously blown, blows hollow container while is vented.
Further：The step 1）Including by Ordinary Compression supercharging air, then cool, it is empty that low temperature compression is made
Gas.
Further：The step 2）Low temperature compressed air goes out from hollow container bottom blowing.
Further：The step 2）Discharge part gas while continuous air blowing.
It is an advantage of the invention that：
1. invention increases blow needle central tube, and continuously air blowing/exhaust, and gas is gone out from container bottom blowing, is made whole
Container internal gas flow, takes away heat.
The present invention blows hollow container using continuous blow, and shortens the molding cycle of extrusion blow hollow container, in practice it has proved that
Effective shorten is manufactured the cycle up to 20% or so.
The present invention will further cool down after Ordinary Compression supercharging air, shorten the molding cycle of extrusion blow hollow container.
The present invention is provided with exhaust shutter, controls capacity, and exhaust ensures container internal pressure while taking away heat.
Blow needle central tube of the present invention is connected with valve group, air conditioner by heat-preserving hose, prevents low temperature compressed air to be heated
Heating.
