Semi- automatic bottle blowing machine
It is suitable for producing PET plastic containers and bottles. It is widely used to produce the carbonated bottles, mineral water, carbonated drink bottle, pesticide bottles oil bottles cosmetics, wide-mouth bottles, etc. Adopting double crank to adjust mold, heavy locking mold, stable and fast, Adopt infrared oven to heat the perform, the perform rotated and heated equally. The air system has been divided into two parts: the pneumatic action part and the bottle blow part to meet the different requirements for the action and blow. It can provide sufficient and steady high pressure for blowing large irregular-shaped bottles. The machine is also equipped with a muffler and oiling system to lubricate the mechanical part of the machine. The machine can be operated in the step-by-step mode and the semi-auto mode.
Semi auto blowing machine is small with low investment, easy, and safe to operate.
Features of Semi-Automatic Blow Molding Machine
1, Infrared lamps adopted in the pre-heater ensures PET preforms being heated evenly.
2, Mechanical-double-arm calmping ensures mould being tightly closed under high pressure and high temperature.
3, Pneumatic system consists of two parts: pneumatic acting part and bottle blowing part. In order to meet different requirements for both acting and blowing, it provides sufficient steady high pressure to blowing, and also provides sufficient steady high pressure to blow large irregular shape bottles.
4, Equipped with silencer and oiling system to lubricate the mechanical pars of the machine.
5, Operated step-by-step and in semi-auto made.
6, Wide-mouth jar and hot-fill bottles can also be made.
The blowing process of the bottle blowing machine main steps:
1) Firstly, put the heated plastic embryo into the mold;
2) Use a clamping cylinder to tighten the mold;
3) Use high pressure or mechanical structure to lock the prototype;
4) Medium and high pressure pre-blowing, while stretching the cylinder action to expand the blank;
5) High-pressure blowing, the preform is shaped according to the mold, and the pressure is kept for a certain period of time;
6) Release the high pressure in the formed bottle, reset the cylinder-take the bottle.
