4  Attached vacuum feeder, convenient and labor-saving
5  Vacuum pump drainage, reduce product moisture, ensure product quality



screen changer
This is 180 (screen area) single board screen switcher
There are many kinds of screen changers, which can be divided into plate type or column type. They can  be divided into single station or double station. The advantages of plate type are material saving and suitable for materials with good fluidity. The advantage of double-column type is that it can work continuously when changing screen, but the disadvantage is that it may wastes a lot because melting plastic in it



metering pumps
1  Importing 250cc (two gear extrusion volume) Mag brand melt metering pump from Switzerland, accurate and stable.
2  ABB AC frequency conversion control, imported sensors accurately detect the pressure before and after the pump, to ensure that products do not deform.
3  Material with different pressures before pump can be adjusted by metering pump and enter distributor and die with the same pressure after pump.
4  K-type thermocouple detects temperature to prevent friction heating caused by high pressure



mold
The heating rod is inserted in the middle, and the opening of the die lip is changed by rotating the adjusting screw of the die lip. The clockwise rotating opening decreases and the counter-clockwise rotating opening increases (only for the die lip has been depressed, and the flexible die lip is reset through the elastic deformation of the material itself). Chromium plating treatment in runner, polishing to mirror, heating area 11, core 9.
The cuboid in the figure below is a co-extrusion distributor. The distribution structure of material is A+B+A

    

three-stage setting table
1  Water Circulation Cooling
2  Weight close to 12t
3  It is equipped with longitudinal movable device. It can be adjusted by electric and manual operation. It is simple and convenient.
4  Vacuum pumps and hydraulic stations are placed at the rear to make the absorbed products of the fixing table hollow.

Cooling bracket, trimming device
Cooling bracket    
The length is 6000mm. The aluminium idler is connected with the tractor and can move as a whole. It can be equipped with an electrostatic eliminator to prevent static electricity.
trimming device    
The number of cutters is four, the width can be adjusted, and the front and back can be adjusted.

tractor
1  Cots are made of nitrile-butadiene rubber in two groups. Domestic famous Dongli servo motor and speed reducer can be replaced by Huichuan or Anchuan motor with Falk reducer according to customer requirements. 2  Cylinder makes upper roll move up and down to adjust traction force

Upper-cut transverse cutter
The sawing thickness is about 15-17 mm, and the width of the door can be adjusted horizontally.
The meter is imported from Korea to Otunix and controlled by encoder.
Longitudinal movement is pneumatic control.

Electrical control system
The control system adopts Siemens PLC 7 series.

It is a new replacement product after wood formwork, composite steel formwork, bamboo-wood plywood formwork and all-steel large formwork. It can completely replace the traditional steel formwork, wood formwork, square wood, while the amortization cost is low.
Formwork characteristics
1. Smooth and cleaness. Formwork splicing is tight and smooth. After demoulding, the surface finish of concrete exceeds that of clear water formwork. It does not need secondary plastering and saves labor and material.
2. Easy to use. Light weight and strong process adaptability,meanwhile it can be sawed, planed, drilled, nailed,which means arbitrary geometry changing in order to meet the needs of various shapes of building formwork.
3. Simple demoulding. The concrete does not touch the surface of the slab, so it can be easily demoulded without demoulding agent, and it is easy to clear ash.
4. High strength of stable weatherproof machinery. Under the temperature range from minus 20 to 60 degrees, it never shrink, expand, crack and deform, and still with stable size , flame retardant and waterproof.
5. Favorable for maintenance. The formwork does not absorb water and does not need special maintenance or storage.
6. Strong variability. Species, shapes and specifications can be customized according to the requirements of construction projects.
7. Reducing costs. Because it has more turnaround times, such as plane formwork no less than 30 times, column and beam formwork no less than 40 times, so the cost is low.
8. Energy saving and environmental protection. Side materials and waste plates can be recycled.
     


      If as Top Plastic Building Formwork Support: The secondary beam spacing is determined according to the thickness of the slab. Under general construction conditions, the secondary beam spacing (center spacing) of slabs less than 150 thickness is 350-400 mm, and the secondary corrugation spacing (center spacing) of 150-250 mm thick slabs is 300 mm. Compared with the normal bamboo plywood formwork, the spacing of secondary beam is increased by 50 mm, and the flatness deviation of concrete surface is smaller, which really achieves the effect of clear water concrete.
      Shear wall plastic building formwork support: taking the wall height of 2800 and wall thickness of 300 as examples, the vertical secondary spacing (center spacing) of 12mm formwork is 250 mm, and that of 15mm formwork is 300 mm. Compared with normal bamboo plywood formwork, the distance between secondary beam and the flatness deviation of concrete surface are basically the same, but the surface of concrete is smooth, and the effect of PP formwork is the sameas clear water concrete, so the visual quality is better.Jwell machinery was established in 1997.
