"Jingcheng" DM series plastic mulch filmblowing machine set is composed of extruder, mono-layer film blowing die head,cooling air ring, hauling machine, coiling machine, temperature and electric controlsystem, etc. It is mainly used to produce LDPE agricultural and mulch films.After changing certain components, it also can produce HDPE, LLDPE films. Thestructural and matched characteristics of the series of machine set are asfollows:

      1. The screw and barrel of the extrudersare uniquely designed by our company, and are processed by domestic famousprofessional manufacturer. It has good plasticization property and high output.

      2. The reliable hard surface gear box hasproperties of low noise, high driving efficiency, stable running and longservice life.

      3. It adopts cylindrical type filter. Thescreen changing period is 7-8 times of common screen changing type. It not onlymakes up the defect of material leakage of fast screen changing device, butalso effectively prolongs screen changing time space.

     4．The diehead adopts central material feeding type spial runners.The material of diehead is high quality carbon steel. Through several times of heat treatmenttechnology, its deformation defect decreases greatly.

5.Hauling roller and coiling roller areconducted dynamic balancing test,rectifying,and accurate grinding processing.

6. The upper hauling device adopts shortchain to transmit.It not only solves the problem of easy clamping and short servicelife of direct connection type,but also overcomes the defecta of largevibration and noise of long chain.

7.It is matched with middle partitiondevice and automatic metering device.

8.It is matched with dual-row chainwheel.which can be operated conveniently and rapidly.

9.The supporting electronic components arefamous domestic brand products.
