Blow expansion ratio When the size and quality of the parison are fixed, the larger the size of the product is, the larger the blow expansion ratio of the parison is. The choice of the Blowing machine product at sea must be determined.
At present, after the reform and opening up, the domestic Blowing machine industry has developed a deep large-scale Blowing machine under the guidance of scientific analysis. However, its appearance still needs to be improved.
Properly and appropriately adjust the blowing ratio, and control the blowing ratio at l: (excluding 1). The product thickness will maintain a certain proportion, and gradually reduce to the main force plane without traction and speed.
In this case, it mainly involves_ Forklifts, passenger cars, others, the demand for more than the machine head, and the takeover area and other factors.
We always hope that everyone can operate correctly. For us, the above equally important operation methods are affirmative, but we must pay attention to them, otherwise it is easy to cause accidents.
Blowing machine equipment is a plastic processing machine. After the liquid plastic is sprayed out, the plastic body is blown to a certain place by using the wind force from the machine.
Jinmingjing machine (300281), polishing machine, remove the cover of the motor bearing, and also have corresponding tools and glue powder.
High machining accuracy of the tungsten wire rod of the press: the adjustment of the DC motor of the ink tray equipment has greatly extended the maintenance time, improved the service life of the machine, and provided material quality at the same time. High processing accuracy of tungsten wire rod: the electric radiation torque of low-temperature silicone rubber products makes the rubber products elastic.

Previous one: internal mixer Next one: open mixer, small open mixer, belt conveyor, tablet press, hydraulic strip cutter.
Open mixer is the abbreviation of open rubber mixer. In plastic products factory, people are used to call it thermoplastic roll,
The internal mixer is mainly used for rubber molding and mixing, and it is one of the main equipment of the rubber plant. The rubber plant uses the above called open mill. What are the precautions for the operation of the plastic molding machine?
● Open the film head and enter the next: when the material of the mixer is under positive pressure, when the material is under positive pressure.
● Turn on the power supply, and the heating of the electric heating coil should not be too high. To ensure that the machine is in good condition.
● No feeding at the feeding position: check several conditions: whether the hopper is out of material; if yes: it is necessary to feed quickly; if not: please check whether the control contactor of the hoist is powered on; if it is, check whether the motor is powered on and loaded, because it is likely that the bottle preform (embryo) has blocked the lifting belt. At this time, it is simple to help lift manually. If the control contactor of the hoist is not powered on, check whether the bottle embryo detection electric eye is not in the same line with the reflector.
● The feeding tray is stuck when feeding: this is a headache. From experience, if the length of the preform (embryo) is longer and the cutting weight is larger, this phenomenon is relatively rare.
Please check your exhaust time setting. If the exhaust setting is normal and the failure occurs once the bottle is blown each time, it can be judged that it is the problem of the exhaust valve. Please open the exhaust valve and check the condition of its springs and seals (another phenomenon of this failure is that the exhaust sound is loud or there is a noise that cannot be discharged).
If you encounter the situation that many molds can not be opened occasionally due to normal production, please check whether the locking pin has a broken screw in it. In addition, please check whether the locking force is too large. If it is too large, it should be readjusted according to the standard.
