Δ Preform feeding system : including preform hopper, preform elevator, preform sorter
All preforms are kept in preform hopper. Adopting the internationally high-security preform feeding method,
these preforms enter the preform elevator from preform feeding hopper, then transported by the elevator to
the preform sorter. By through two inclined rollers that rotate upward at the same speed,these preforms falling
into the gap of the rollers are automatically arranged and outputted; at the same time, the excess preforms will
be removed by preform removal wheel and return into the feeding hopper again though return pipe.
The process of preform sorting is fully automatic, with high efficiency and without damaging these preforms.
Δ Preform ionic gas de-duster
The positive and negative ion generators neutralize static electricity on the surface of the preform.
Clean compressed air blows the dust on the surface of the preform, and vacuum vacuum suction.
Δ Preform heating furance
► The system is equipped with seven-segment infrared heating lamps;
► It adopts the optimal heating process state of the preform screw thread mouth downward, to reduce
the bad influence of the upward convection hot air on the preform screw-thread mouth, and it is more
convenient to heat the embryo body of preform fully in a limited space.
Besides, it will be more energy efficient and more uniform.
► The Air flow, bottle-neck cooling waterway and air-cooling protection devices in the heating zone have
been carefully designed to effectively protect the bottle-neck.
► Through the furnace temperature sensor and infrared thermometer, the temperature parameters of the
light box and preforms are transmitted to the PLC, and the actual temperature and setted temperature
of these preforms can be displayed and set through the computer screen;
► Through the powerful PID calculation function of PLC, the power of each layer of heating lamp is adjusted
in real time, so that the whole preform can obtain the best temperature curve.
Δ Blowing station
1). These heated preforms are sent to the mold by specialized mechanical hands that along a certain cam curve.
The preform is stretchedand pre-blown, and then passed through the high pressure gas to be finally blown into
one bottle shape.
2). The high-pressure valve unit uses the high-quality products of the Norgren Swiss factory to ensure the stability
and reliability of the blow molding process.
3). The independently developed integrated high pressure valve block and sealing cylinder have smaller dead gas
space than similar products, which is better to reduce the consumption of high pressure compressed air.
4). The high-back-pressure structure inside the sealing cylinder enables the sealing of the nozzle with lower air pressure,
which reduces the impact of the nozzle on the mold, and can reduce the consumption of low-pressure compressed air.
5). Quick and easy positioning of the mold mounting structure, combined with the use of a one-way stop valve &
cooling water quick-connect connector, making the replacement of the mold faster and more convenient, the skilled
workers only take one hour to replace the full set of molds.
