Product Overview
seven-layer co-extrusion blown film unit
Purpose:
The main feature of the seven-layer co-extrusion blown film unit newly developed by our company Chengheng Plastic Machinery Co., Ltd. is that it adopts a plane stacked head, which is divided into seven layers. There is no dead point, and there is a heat insulation layer between the plates, which can individually control the temperature of each layer of the machine head. The temperature difference between adjacent layers is between 50°C (degrees). The entire machine head is compact and the machine The head also adopts a rotary upper traction and constant control fully automatic winder. The products produced by this unit have the characteristics of high strength, many layers and good uniformity.
The extruder adopts a vacuum automatic feeding device, the hopper is made of stainless steel, the screw, barrel and screen changer, and the filter is made of 38CrMoAI (chrome-molybdenum-aluminum) material, which has good thermal mechanical stability , It also meets the hygienic and environmental protection requirements of the products. The motor adopts frequency conversion control, which can accurately adjust the speed of the main machine and control the feeding amount.
The machine head of this unit adopts a double-channel multi-layer plane stacking head, and the plane stacking head is made of disc-shaped sheets, and each layer of disc-shaped sheets has two layers.
Two layers of film can be extruded, each layer is evenly heated, which effectively improves the material flow performance, side feeding, less inflection points in the flow channel in the head, and no dead angle

The whole machine head is made of 42CrMo (chromium molybdenum) material, after a special heat treatment process, the internal electroplating and polishing processing methods ensure a smoother film surface, and the mouth film of the machine head can be adjusted to reduce the uniformity of film thickness The precise internal structure design greatly improves the uniformity of material extrusion.
The operation part of the machine is all completed by the touch screen, and all the operation buttons and display instruments are all completed by the touch screen. The three touch screens can realize the man-machine dialogue very conveniently. The main control part adopts the Austrian B&R computer programmable controller (PCC).
