The chiller for the carbonated bottle is about five times larger than the chiller for the water bottle. How much chiller is needed for the carbonated beverage bottle blowing machine to blow the bottle? For example, the water and air jacket are damaged, and the maintenance works are more troublesome. However, the most significant hidden danger of the equipment is mainly on the seals of the water jacket and air jacket.

How to operate the bottle blowing machine, and which accessories should be checked?Īs long as the equipment is controlled strictly following the method in the instruction manual and the performance of each safety door is checked regularly, the equipment as a whole is safe.

If the customer’s conditions permit, you can refer to the imported machine to install central air-conditioning in the production workshop to keep the ambient temperature of the workshop at an average temperature. It only needs to increase the air-cooling or water-cooling of the bottle mouth. During the heating process, the temperature continues to accumulate, and the bottle mouth bulges and deforms. What should I do if the bottle’s mouth-blown by the bottle blowing machine is deformed?īottle mouth deformation Generally, during the heating process of the preform, the transmission chain drives the bottle base to transfer the temperature to the preform mouth. It is recommended that the stretching ratio between the preform and the bottle body is preferably 1:2.5 (excluding the mouth part), and at the same time adjust the heating temperature to extend the pre-blowing. The common factor for bottle accumulation is that the stretching rod is not adjusted in place. What should I do with the bottom of the bottle blown by the bottle blowing machine? 5D/12D/20D Double Station Blow Molding Machine Common problems and solutions in the blowing process of the bottle blowing machine 1. Still, hot-filled bottles must ensure that it is fully released above the glass transition temperature. For gas-filled beverage bottles, it can resist internal pressure, which is beneficial. In the process of rapid blow moulding and cooling, induced stress is generated in the bottle wall. if possible, it is better to control the overall temperature distribution of the preform, bottle The temperature gradient of the inner and outer walls of the blank. Therefore, it is necessary to adjust: stretching start timing, stretching speed, pre-blowing start and end timing, pre-blowing pressure, pre-blowing flow, etc. The three actions are concise, but they must be well-coordinated, especially the first two steps to determine the overall distribution of the material and the blowing quality. The blowing process includes stretching-blowing once-blowing twice. This temperature is determined by the length of the cooling time during the injection moulding process (such as the Aoki bottle blowing machine), so the relationship between the injection and blowing stations must connect. The PET exhibits a highly elastic state in this interval and becomes a transparent bottle after rapid blow moulding and cooling, and setting. The wall thickness of the preform should not exceed 4.5mm.īlowing is carried out between the glass transition temperature and the crystallization temperature, generally controlled between 90 and 120 degrees. It is necessary to control the stretch-inflation ratio:ĭo not exceed 3.5-4.2 in the radial direction and 2.8-3.1 in the axial direction.

It has good airtightness.Īlthough stretching helps to increase strength, it should not be overstretched. It improves the tensile, tensile, and impact strength. In this process, the PET chain is extended, oriented and arranged in two directions, which increases the mechanical properties of the bottle wall.

The blow moulding machine process of the bottle blowing machine is a two-way stretching process. 5D/12D/20D Double Station Blow Molding Machine The process flow of the bottle blowing machine Significantly accelerate the rate of production. The automatic bottle blowing machine combines the two operations of bottle blowing through the operation of the manipulator, eliminating the need for the manual process of putting the preheated preform into the blowing mould. The preheated preform is placed in the blow mould, and the inside is inflated with high pressure to blow the preform into the required bottle. To maintain the shape of the bottle mouth, the preform mouth does not need to be heated, so a particular cooling device is required to cool it. Warm-upĪn infrared high-temperature lamp irradiates the preform to heat and soften the preform.

The blowing process of the bottle blowing machine is divided into two parts. The principle of the bottle blowing machine
