Screw and Barrel for Rubber Machine manufacturers take you to understand the use conditions and methods of rubber extruder barrels

Screw and Barrel for Rubber Machine manufacturers tell you that for a rubber extruder, the screw and the barrel are very important components. In order to play the role of the barrel, the operator should master the conditions and methods of its use.

1. Heating method
Screw and Barrel for Rubber Machine manufacturers tell you that resistance heating is often used in urgent heating methods, and thermocouples are used to achieve the effect of segmental temperature control. Resistive heating uses electrical resistance to generate heat that heats the barrel, which in turn transfers heat to the raw material inside the barrel. Screw and Barrel for Rubber Machine manufacturers tell you that this heating method has the advantages of small price increase, simple operation, low cost, and easy maintenance. Of course, there are also some other heating methods, which will not be repeated here.
2. Heating power
Screw and Barrel for Rubber Machine manufacturers tell you that two points need to be considered when determining the heating power of the barrel. One is to meet the amount of heat used when the material is plasticized, and the other is to consider the productivity during injection molding to ensure that The barrel temperature and speed meet the requirements. Screw and Barrel for Rubber Machine manufacturers tell you that generally speaking, the heating time for small machines should not exceed 30min, and if it is a large and medium-sized machine, the heating time should be about 1h.
3. Cooling method
Screw and Barrel for Rubber Machine manufacturers tell you that under normal circumstances, the barrel does not need an additional cooling control system, and natural cooling can meet the needs of production, but if the temperature of the feeding port is relatively high during use, it is prone to feeding difficulties. At this time, in order to ensure the smooth progress of the feeding, it is necessary to install a cooling jacket (slot) at the feeding port, especially when running at a high speed, it is necessary to perform cooling and temperature control on the machine.
In addition, when using the rubber extruder barrel, it is also necessary to do electrical protection work. The Screw and Barrel for Rubber Machine manufacturer tells you that before starting the operation, you should check whether the power line is bitten by mice and whether the plug is in contact. If it is not good, whether the voltage and current meet the requirements, after the end of the operation, make sure that the power supply of the equipment has been disconnected.
