"Jingcheng" DM series plastic mulch
film blowing machine set is composed of extruder,
mono-layerfilm
blowing die head, cooling air ring, hauling machine, coiling
machine, temperature and electriccontrol system, etc. It is mainly
used to produce LDPE agricultural and mulch films. After
changingcertain
components, it also can produce HDPE, LLDPE films. The structural
and
matchedcharacteristics of the series of
machine set are as follows:
1.
The screw and barrel of the extruders are uniquely designed by our
company, and areprocessed by domestic famous
professional manufacturer. It has good plasticization property and
highoutput.
2.
The reliable hard surface gear box has properties of low noise,
high driving efficiency, stablerunning and long service
life.
3.
It adopts cylindrical type filter. The screen changing period is
**8 times of common screenchanging type. It not only makes up
the defect of material leakage of fast screen changing device,
butalso effectively prolongs screen
changing time space.
4.The die head adopts central
material feeding type spial runners.The material of die head is
high quality carbon steel. Through several times of heat treatment
technology, its deformation defect decreases
greatly.
5.Hauling roller and coiling roller
are conducted dynamic balancing test,rectifying,and accurate
grinding processing.
6.
The upper hauling device adopts short chain to transmit.It not only
solves the problem of easy clamping and short service life of
direct connection type,but also overcomes the defecta of large
vibration and noise of long chain.
7.It
is matched with middle partition device and automatic metering
device.
8.It
is matched with dual-row chain wheel.which can be operated
conveniently and rapidly.
9.The supporting electronic
components are famous domestic brand
products.
