PP hollow construction board production line introduction:


The hollow board production line is used for continuous production of grid plates in PC, PE and PP. Products are widely used in architectural decoration, advertising layout, road sound insulation for packaging. PE and PP grid plates can be used as packaging boxes instead of cardboard boxes, which are light in weight, high in strength, moisture-proof and anti-corrosive. Finished sheet width 1220-2100mm pp hollow grid board equipment, thickness 2-12mm.


1. Extruder: The special design of the screw and advanced temperature control system ensure the plasticization effect of the raw material is good and the high output is stable and extruded.


2. Screen changer: The hydraulic quick change screen device is adopted to make the screen change process fast and effective, the double station and the special sealing structure ensure the stable operation of the screen changer.


3. Mold: The mold is made of high-quality alloy steel with high-activity throttling device, so that the distribution pressure of the raw material flow in the die is uniform, and the upper and lower die are differentially adjusted to ensure uniform thickness of the upper and lower walls.

4. Vacuum setting table: There is a fast heat exchange refrigeration system in the shaping system. And the vacuum system is effectively staggered, the suction distribution is even and reasonable. Qingdao hollow grid plate equipment, this distribution ensures the setting accuracy. The vacuum system consists of two separate subsystems. Each subsystem is equipped with a plurality of three-point fixed-cycle vacuum groups, each of which carries a vacuum adjustment system and a vacuum display system to make the vacuum on the surface of the plate uniform and stable.


5. Traction machine: The tractor is distributed with the first group and the second group. The first group of tractors are high-power, large reduction ratio, multi-roller type, with excellent low-speed dynamic rotation performance, large traction force, and can simultaneously pull the plates out of the vacuum setting table. The second group of tractors cooperates with the product stress. It is also equipped with a trimming device pvc hollow grid plate equipment to ensure the effective width and edge quality of the board.


6. Stress eliminator: The advanced large-area conduction heating method can effectively eliminate the stress of the plate and further increase the flatness of the plate.


 Cutting machine: equipped with precise instantaneous fixed length cutting and automatic lifting and unloading device, special alloy wear-resistant cutting edge to ensure the quality of the cut surface of the board. Thick plates of 5mm or more are sawed.


 The device is used for the production of PC, PP, PE hollow grid panels. Products are widely used in construction, decoration, advertising layout, road noise isolation and packaging. PP hollow sheet can be used as a packing box instead of carton, with light weight, high strength, moisture proof and anti-corrosion. The finished board has a width of 1220-3000mm and a thickness of 2-16mm.
