PRODUCTS:3-layer Co-extrusion Haul-Off rotary film Production line  
MODEL:SQW

 

Ⅰ.The main purposes:

 

membrane within the cold water level rotating co -extrusion traction multi-storey composite film production line, I was the adoption of advanced foreign technology, optimize the common development of multi-layer co-extrusion technology from the international advanced level in the plastic blown film unit, is At present the ideal replacement machinery blown film products, but also the development direction of the development of plastic machinery.

 

This series of blown film unit has its unique advantages in cold traction device rotating series of scientific and rational, reliable operation, better foot high accuracy, high speed color printing, composite, coated products require the use, production efficiency, wide Fume used in the production of substrate, the protection of film, cable film, polymer adhesive film, liquid film, film-industry products, and continuously expand the scope of application.

 

    Ⅱ. The main characteristics:

 

1, the bubble in the film cold, the unit production capacity significantly improved, enhancing transparency film, in the cold advanced and reliable device, membrane bubble packs Drive small deviation.

 

 2, the level of use of traction-swing rotation, a smooth rotation, rotation speed of Promise regulation.

 

3, to replace rotating die, die simplified structure. Completely solve the rotating die caused by leaking material, sealed difficult, difficult maintenance and other problems.

 

4, vol overcome the size of the first film, elastic-quality problems, such as to ensure the smoothness of a good film.

 

5, EPS photoelectric corrective system, automatically correcting direction, and ensure an orderly winding film.

 

6, air-cushion-oriented steel rollers and a new arc-roll-oriented exhibition, film and tidy formation.

 

 7, high-precision molds and wind ring cooling system to ensure that a good film thickness uniformity, output and high efficiency.

 

8, advanced and reliable operation of electrical systems.

 

 9, to raw materials: LDPE, LLDPE, HDPE, EVA, and so on.

 

    Ⅲ, the three-tier co-extruded in the cold and the wind dies, Central

 

1, the International digestion and absorption of advanced technologies, use a computer to coextrusion die and wind ring has been optimized design, with significant competitive advantages.

 

2, die within a scientific and rational flow design, material flow evenly distributed to ensure that the production of thin film products with good thickness uniformity, but also greatly shortened the time to adjust with membrane and mold, reduce the film thickness uniformity of regulation time is too long and the Members of material consumption and waste, thereby lowering the production cost of film products.

 

 

 

Third, the three-tier co-extruded in the cold and the wind dies, Central

 

 1, the International digestion and absorption of advanced technologies, use a computer to coextrusion die and wind ring has been optimized design, with significant competitive advantages.

 

 2, die within a scientific and rational flow design, material flow evenly distributed to ensure that the production of thin film products with good thickness uniformity, but also greatly shortened the time to adjust with membrane and mold, reduce the film thickness uniformity of regulation time is too long and the Members of material consumption and waste, thereby lowering the production cost of film products.

 

 3, the design of fluid flow, no dead ends: the fine-grinding, polishing chrome plated hardware, surface finish, effectively shortening the material in the mold of the residence time, reduce the formation of crystal point, the plot easy to overcome internal mold materials and paste Expected, Coke materials, so that the production of thin film products with good transparency and gloss.

 

 4, a new type of highly efficient cooling winds Central: Optimal Design of the new Central wind, air-flow stability in uniform, can provide a high cooling effect and membrane bubble stability, thus ensuring a high yield, good transparency and thickness tolerance.

 

 5, before finishing in the mold, after hardening and elimination of stress to ensure that die in size to maintain long-term stability.

 

 6, Die Making: self-precision processing, and some processes of the Association of imports by the processing center to complete 4-axis linkage to ensure that the processing precision molds and materials at all levels of uniformity.

 

 7, a mold runner after plating, polishing and grinding hard chromium, wear-resistant corrosion-resistant, long life.

 

Fourth, the film bubble cooling system: membrane within the bubble cooling device (IBC) is a proven increase blown film production line production methods, to the film by providing air-conditioned bubble within the flow of air into the device and the heat from the exhaust air device Composition. In the cold devices:

 

 (1) Two sets of fans can speed, variable frequency control.

 

 (2) An ultrasonic sensor (Germany births) of the digital-diameter gas control system.

 

 (3) The presentation of high-precision control system Path, a PLC control, through the fan speed adjustment of the regulation of gas, high-precision control, the film tracks the bubble pack of small deviation.

 

 (4) Heat exchangers control air temperature.

 

5, Blown Film Auxiliaries: including traction and auxiliary winding auxiliary

 

1, auxiliary traction: four-storey tower, the overall stability, easy to operate.

 

2, winding machine: duplex bit passive friction winding, A, B or volume of sub-adjustable.

 

3, EPS photoelectric corrective system, automatically correcting orientation:

 

(1) Non-contact test for quick detection.

 

(2) Anti-interference capability and long-term stability.

 

(3) A memory function, automatically correcting direction, film deviation can automatically returns to ensure that film winding tidy.

 

(4), closed-loop tension control system: The new automatic tension control system, according to the film by measuring changes in tension, and tension automatically adjust to ensure that film winding constant tension.

 

6, the main quality indicators:

 

(1), the smooth functioning of the entire production lines, electrical control of sensitive and reliable,

 

(2), blowing 0.02 mm ~ 0.15mm film products.

 

(3), may be blowing 800 mm ~ 3200mm wide film products.

 

(4), uniform thickness distribution, film formation volumes, tidy and constant tension.
