First, the structural characteristics of single screw extruder
Single screw extruder is currently the most widely used domestic extruder. Its structure
Features are: extruder plastic system is composed of a screw and barrel with the composition of the material
Bucket, electric heating and cooling systems and porous plates and filters and other components with the work to complete the original
Material of the extrusion plastic work.This single screw extruder as long as the replacement of different structural screw,
You can complete the different kinds of thermoplastic extrusion molding work.
Second, single E pole extruder specifications and basic parameters
The basic parameters of the single screw extruder specified in ZBG 9500.1-88 are shown in Table 2-1 and Table
2-2. Table 2-1 is a basic single-screw extruder consisting mainly of extruded polyolefin-based plastics
Parameters can also be extruded to produce soft PVC plastic products. Table 2-2 is based on extrusion
Forming a soft, hard polish ethylene plastic products consisting mainly of single screw extrusion 'machine basic
The basic parameters of the single screw extruder for forming polypropylene plastic products are shown in the table.
JB / T 8061-1996 of the provisions of the single screw extruder Tsuen Township number
The 2. The basic parameters of single screw extruder
0 screw diameter refers to the screw part of the outer diameter of the screw. D said, the unit
For mm.
O screw length to diameter ratio
Expressed in LID.
③ screw speed range
With ,, am-nmio.
Refers to the ratio of the length of the screw thread to the diameter of the screw.
Refers to the maximum number of revolutions and the minimum value of the screw.
④ Motor power refers to the motor power for driving the screw rotation. With P,
The unit is kW.
The Barrel heating power refers to the barrel with a resistance wire heating power consumption. The unit is kW.
⑥ barrel heating section of the barrel with a resistance wire heating sub-n control, but also temperature
Control the number of segments.
O extruder production refers to the extruder per hour production of plastic products quality (weight
child). Expressed in q, the unit is kg / h.
⑧ nominal ratio of power refers to the extruder per hour production of plastic products required for electric quality
The sum of the machine power is expressed by P ', ie P' = P / q., In kW / (kg / h).
⑨ than the flow refers to the rotation of each screw produced by the screw in the quality of plastic products. It can be
The production efficiency of the extruder is expressed by q = qj / n $ M. The unit is (kg /
h) / (r / min). ,
The center of the center of the barrel of the extruder is the height of the center line of the screw
h, the unit is mm.
