Q:What raw material does the extruder use?
The utility model has the function that the plastic melt from the extruder barrel is well distributed in the die runner so as to be extruded and formed from the die at a uniform speed. The forming action of an extrusion die is in the process of complete extrusion (see plastics processing). A plastic extruder consists of an extrusion system, a drive system and a heating and cooling system. The classification system of extrusion system includes 1. extrusion screw, barrel, hopper, head, and mould, plastic extrusion system by plasticizing evenly into the melt, the establishment of Liu Hesheng basic information name in this process and Liu Hesheng taught: - professional engineering
Q:What is the adjustment method of China's extrusion machine die?
(2) run mode: plastic glue on the plasticizing after adjustment for mold screw, die according to how much glue circle, ran glue, side adjustment, adjustment should be loose thin screws, tighten the screws run glue thick; at the same time sampling check plastic thickness is eccentric, until evenly so far, then tighten the screw die respectively.
Q:Plastic double screw extruder, pumping air will accumulate material, how is it going on?
Adjust the assembly and check the exhaust block
Q:Why do screw extruders often extrude light red plastic products?
Cause this situation. Please clean the hopper thoroughly. The screw is also drawn out and cleaned up. It should be easy to solve.
Q:Taper twin screw extrusion machining of plastic masterbatch? What ancillary equipment do you need?
Can, but need feeding machine and related auxiliary mixing granulator, the cost is not low, but the effect is less than double make flat,
Q:Extrusion blow molding machine, storage or continuous type good?
and material in the screw for a long time to use the storage type is also in order to meet the demand for raw materials productsIf you are doing small things, your hourly output will not consume the maximum hour.
Q:why production is not strong?I have several new co extrusion machines, but the blown plastic bags are not produced by others
The recipe is either too large or too small. Do you mean that the tension is not enough, transverse or vertical?
Q:Basic parameters of extruder screw
2. The ratio of the length to diameter of the screw, the length of the screw L/Ds and the ratio of L to the diameter of the screw Ds is called the ratio of length to diameter. When the other conditions are constant (such as the diameter of the screw), increasing the ratio of length to diameter means increasing the length of the screw. The L/Ds value is large and the temperature distribution is reasonable, which is beneficial to the mixing and plasticizing of plastics. At the same time, the heating time of the plastic in the barrel is longer, and the plasticization of the plastic will be sufficient and more uniform. So as to improve the quality of machine plastics. If the plastic quality requirement is constant, the rotation speed of the screw can be increased after the ratio of length to diameter increases, thereby increasing the extrusion amount of the plastic. However, too large length diameter ratio, power consumption will increase the screw, and the screw and barrel of the processing and assembly of chicken more difficult; the possibility of screw bending will increase, will cause the abrasion of the screw and the inner wall of the cylinder, reduce the service life. In addition, the heat sensitive plastic, large diameter and long retention time than thermal decomposition, the plasticizing and impact plastic extrusion quality. Therefore, in the full use of the advantages of increasing the ratio of length to diameter, the selection should be based on the physical properties of the processed plastics and the quality requirements of the products.
Q:There is a 90 extrusion machine, used in the production of communication cables (outside the cable core is extruded with a layer of LLDPE), now is the configuration of Y2-280M-490KW167A inverter type ACS510197A + ABB), General Motors now found low speed when the current is too large, what reason? How to solve? The details are as follows: used for communication cable production HYA30*2*0.4, 1, line speed is 50 m / min, inverter display frequency 35.3HZ current: 116A; 2, line speed is 40 m / min, inverter display frequency of 28.2hz, current: 140A3, line speed is 35 m / min, the frequency converter significantly method: 157A 24.6HZ frequency current, because the product variety and technical reasons, we need to be in the frequency of 10HZ production. Now, it seems that if I reduce the speed again, the current will probably exceed the rated current. What should I do? Is the motor changed to frequency conversion motor? Or inverter? How to solve? Please heroes pointing, thank you!
See the ACS510 manual, this type of inverter used in fan pump type, 2605 control methods of determining its U/F, the default value is 2 (the square type, namely fan pump type); for constant torque load, should be set to 1 (linear). When not available, does the debugger not modify the parameter to 1? If that's the case, will the top floor say what happened?
Q:Ask everyone about the extrusion machine at the wire factory...... How do you adjust the speed of the motor?
One is the use of frequency converter connection, in accordance with the frequency converter user manual guidance method to adjust the speed, in addition to the use of electromagnetic speed control motor, through the speed box above potentiometer adjust speed.
