1. What should I do with the bottom of the bottle blown out by the blow molding machine?
Analysis: The common factor of bottle accumulation is that the stretching rod is not adjusted in place. It is recommended that the stretching ratio between the preform and the bottle body should be 1:2.5 (excluding the bottle mouth), and at the same time adjust the heating temperature to prolong the pre-blowing gas.
2. What should I do if the mouth of the bottle blown by the blow molding machine is deformed?
Analysis: The bottle mouth is deformed. Generally, during the heating process of the preform, the transmission chain drives the bottle base to transmit the temperature to the preform mouth. During the heating process, the temperature continues to accumulate, and the bottle mouth is swollen and deformed. It is only necessary to increase the air cooling or water cooling to the bottle mouth. If the customer's conditions permit, you can refer to the practice of imported machines and install central air conditioners in the production workshop to keep the ambient temperature of the workshop at normal temperature.

3. How should the blow molding machine operate, and which accessories should be checked?
Analysis: As long as the equipment is controlled strictly according to the method in the instruction manual, and the performance of each safety door is checked regularly, the equipment is generally safe. However, the biggest hidden danger of the equipment is mainly on the sealing parts of the water jacket and the air jacket.
4. How many chillers does the carbonated beverage bottle blowing machine need to blow bottles?
The chiller equipped with the carbonated bottle is about 5 horses larger than the chiller equipped with the water bottle. A simpler algorithm can be calculated by 1200 bottles/horse, for example: 36000 bottles/hour can be equipped with a 30-horse chiller. In order to ensure the stress requirements of the bottom of the carbonic acid bottle, the cooling time is generally 1.2 seconds, and the temperature of the bottom mold is 11 degrees. The number of lamp zones equipped with the heating furnace can refer to the configuration of the hot filling machine, and the effective heating time of the preform should be no less than 33 seconds.
5. What is the maximum temperature resistance of the amorphous bottle mouth of the hot filling bottle blowing machine? How many grams of preform do I need?
Analysis: At present, the preform mouths used in the production of hot-filling bottles in the industry are generally divided into crystalline mouths and non-crystalline mouths, and non-crystalline mouths are divided into 28 mouths and 38 mouths. As far as the bottle mouth is concerned, the crystalline mouth can withstand 100 degrees without deformation, but the upper limit of heat resistance of the non-crystalline mouth is only 92 degrees. If it is higher, the bottle mouth will be deformed by heat. The preform and gram weight used for blowing the medium temperature bottle should preferably be selected according to the requirements of hot filling.
