We often use I. S Machine to produce glass bottles of various sizes and styles. During production period, the speed of processing glass bottles is not the same, some fast and some slow.What are the factors that affect the processing speed of the equipment?
1. The bottle preform
Bottle blank, also known as type blank, is PET granules injection molding, after injection molding or reheated bottle blank cooling for more than 48h, and the storage time of the used bottle blank can not exceed 6 months, different production dates, especially long spacing bottle blank can not be mixed. The main reason is that the raw material type used in the bottle blank, the proportion of secondary materials mixed in and the residual stress in the bottle blank are different, and these factors have a serious impact on the molding process of the bottle making machine, which should be viewed in detail according to the different environment.
2. Heat
The heating of the bottle blank is completed by the heating furnace, which is set manually and adjusted automatically. The height of the heating furnace is about 25mm, 19.6mm away from the delivery wheel. However, if the heating furnace is not adjusted properly, it will form the uneven distribution of the blown bottle wall thickness (as light as below), the bottle mouth becomes large and exceeds the standard, hard neck and other product defects, and even form the torsion fault of mechanical parts.
3. The blow
The function of pre-blowing in the process of blowing is to make the bottle blank take shape and increase its longitudinal strength by longitudinal stretching with the stretching rod. The whole process is the pre-blowing CAM in the process of blowing the three-way valve to the pre-blowing position, and completed by the one-way valve. Pre-blown position, pressure and flow rate,these factors all affect bottle quality.
4. Stretching rod
The stretching rod is a device for stretching the heated bottle blank at the same time with the co-operation of pre-blowing. It is reset after high pressure blowing and before exhaust. The stretching rod can move smoothly vertically up and down in the bottle blowing process of the bottle making machine, the driving pressure is 0.55-0.8mpa, and the gap with the bottom die is 2.3-2.5mm, that is, the thickness of the bottle blank is 1/3-1/2. If the gap is big, the center point of the bottle bottom will shift The clearance is too small and the center point will become thin.
5. High pressure blows
The role of high pressure blowing is to make the molten material fully extended, close to the mold body, so that the bottle fully formed, at the same time stop transverse stretching, further its transverse strength. The main influencing factors are position and pressure.
6. The mold
Mould is one of the important factors affecting the bottle blowing. The bottle body is a huff mold, and the bottom of the bottle is independent, which is a typical blow molding mold. In the process of consumption, we should adhere to the mold constant temperature, clean, exhaust holes. When the mold heating and cooling system presents problems, there will be defects such as tilted bottleneck, tilted bottle, volume and height change, and heavy bottom. Maintaining the constant temperature of the mold can also avoid the mold surface condensation.
The bottle blowing process of bottle making machine is affected by the above six factors. When we use the equipment to produce glass bottles, we should operate in accordance with the relevant requirements. In the process of processing, we should pay attention to the above points so as to complete the processing of glass bottles with high efficiency.
