Plastic extruder bearing in the plastic extrusion machine, the plastic extrusion machine is an important part of the drive mechanism.
Which controls the rotation speed of the screw, the screw rotation speed determines the production of plastic extrusion machine.
The power needed by the polymer viscosity (
Resistance to flow)
Decision.
And polymer viscosity depends on the temperature and flow rate, with the increase of temperature and shear stress decreases.
Plastic extruder with mesh, impurities will stop on the screen.
To avoid shutdown, mesh should be able to automatically change.
When processing resin with impurities, such as recycle material, this is particularly important.
Squeeze molding machine screw feed zone, plasticizing, melting, the temperature according to the technological parameters of plastic particles and model according to the screw diameter of 20, 36, 52, 65, 75, 95, 120, 135.
Plastic particles when heated by a screw motion to change the original state, type many, the concrete application.
Frequency conversion capacity is proportional with the diameter of the screw, then according to the different adjustment of raw materials.
So say, plastic extrusion machine bearing need to choose a good material for who, is, of course, linqing bearing manufacturing co. , LTD!
