            Three floors 2600

            The unit adopts patented three-layer co-extrusion internal cooling die, horizontal traction rotation device and automatic center winder. The automatic center winder has three winding methods: surface friction winding, center winding and gap winding, which can adapt to various functional film winding such as ultra-thin, ultra-thick film and self-adhesive film. The machine is highly automated, easy to operate and maintain, and is widely used in the production of LLDPE, LDPE, mLLDPE, HDPE, PP, PA and other high quality films.

            Surface friction rewinding

            Function

            Eliminate manual mixing. Flexible control of layer thickness for each extruder layer. Combined with internal cooling control. Online direct control of each layer thickness.

            Advantage

            Special exhaust design.

            Tension closed-loop control.

            測厚儀.png

            Thickness Gauge

            Function

            Non-contact capacitive sensors designed for in-line film thickness measurement, which measure thickness in-line without scratching the film surface, are especially suitable for the production of more viscous and surface-sensitive films.

            Advantage

            The probe has two sensors that work in parallel to produce separate capacitances. This combination allows the thickness to be calculated regardless of the distance. It does not affect the results in the case of continuously changing air gaps (ranging from 100 to 350um).

            Horizontal upward rotating traction device

            Function

            Horizontal rotary traction adopts horizontal ±360°swinging rotation, with constant film linear speed, scientific and reasonable structure, energy-saving and easy maintenance. It replaces the rotary die head, simplifies the die head structure, and completely solves a series of problems such as long rotary die head runners, difficult melt sealing, easy material leakage, uneven heating, difficult maintenance, and large film tolerance. At the same time, it simplifies the difficulty of formulating materials and controlling production process for multi-layer co-extruded products. If combined with the film bubble internal cooling system, it can produce film products with higher transparency and better physical properties.

            Advantage

            The film produced by using this device has extraordinary flatness and precise cylindricity of the film roll, so that the film thickness deviation triggered by the die head, wind ring and tower is evenly distributed on the film roll, which ensures high quality of film roll forming in the winder and meets the requirements of high precision and high speed printing lamination.

            中心收卷系統.png

            Centralized winding system

            Function

            It adopts the center of the reel to wind up, plus the taper control of the system to calculate the winding diameter in real time. It can overcome the problem of equal tension due to different roll diameters. Finally, it can achieve the purpose of tightening the product inside and loosening it outside, so that the film roll will not be deformed.
