PET Bottle Automatic Blow Moulding Machine for Water Bottle / Soft Drinks Bottle / Oil Bottle

This series is widely applied in making PET bottles for mineral water, carbonated soft drink, medium temperature filling drink,

milk, edible oil, food, pharmacy, daily chemical……etc.

Machine Features and Advantages

Summary

BLMS Series linear blow molding machine is a high speed automatic PET blower designed and developed with the most

advanced bottle blowing technology at present, the advantages of which can be described as speedy, stable, simple, general

purposed and environmental safe. It is mainly applicable in blow molding cold filling and mesothermal filling PET containers for

drinking water, beverage, food, daily chemical products, etc. The machine yields abundantly with high efficiency.The capacity of

each cavity has been increased to 1750bph from original 1000bph when the bottle size is equal to or less than 600ml

respectively, which can meet the high-end customer's requirements. Equipped with preform auto loading system, the machine

works fully automatically with consistent performance and high speed, without any operator's interference during the whole

processes. Accordingly, chance of contamination can be reduced manifestly, which assures the quality of products.

Technology Development

The mold movement mechanism: the servo motor reducer synchronical transmission system is adopted to fulfill the

reciprocating up and down motion of the two hinge mechanisms on both sides of the mold hauled by two linkage rods

respectively. In this way, the two mold holding plates in the middle move oppositely or towards each other, which is generally

known as mold opening and closing. The hauling wheel driven by the servo motor makes clockwise rounds continuously. Each

round leads to a complete cycle of mold holding plates movement------open and close. Also the high pressure air supercharged

mold locking mechanism is applied which buffs the impact between mold plates and effectively protects molds. Besides, it does

help to reduce the visibility of parting lines on finished bottles. The servo motor driven mold movement mechanism is designed

and created upon rigid engineering simulation analysis, which ensures that the series of the mold motions are simple, accurate,

consistent and speedy, making cycle time 0.3~0.5 seconds.

The stepping mechanism: the transmission motions of preform heating, delivering and bottle out feeding are all the results of

a servo motor's synchronical high speed and precise positioning. (Adopted servo motor to drive the chuck, and the chuck

moves a round, a stepping cycle is completed. It means that at the meantime, loading 4 pcs performs, 4 pcs heated performs

come into the blow mould, 4 pcs finished bottles are taken out by the robot.) Slider stepping by orbit is swift and stable with less

cycle time and higher efficiency.

The stretching mechanism: the stretching rods are driven by a servo motor all at once, which ensures the synchronicity of the

motion of the rods and makes it easier to do adjustment prior to production.

(After interchanging the blow mould, makes it much easier to adjust the height of stretching rods, just need to input the data on

the touch screen, no need to do the adjustment by manual.)

Energy-efficient heating system

Using the latest technology of energy saving type infrared lamp,the penetration of lamp is stronger, more uniform! And

compared to the conventional lamps, it can save electricity up to 30-20%.

The homothermal heater adopts auto reflection and closed loop adjusting system which have the power supplied constantly in

proportion, not affected by the fluctuation of voltage. Each lamp pipe in the heater can be controlled individually. Moreover, the

heaters are equipped with the converter controlled circulating air cooling system that can keep the temperature constant inside

the heater and preforms heated consistently, which makes high good part rate. Additionally, the homothermal heater works

excellently in the condition where temperature fluctuates greatly (10℃~30℃). The positioning of heating stepping system is

conducted by the servo motor, swift and stable.
