Product Description

Three-layer co-extrusion film blowing machine/down blowing method

The small film blowing machine refers to the technological process that the double-folded plastic film made by compressed air huffing, vane cooling and frequency conversion traction and the plastic melt being extruded through dies at a certain temperature and certain cutting force.

The small film blowing machine consisted of single screw extruder and film blowing tower. It is mainly used for testing the film blowing feasibility of polymer materials and the colloid status contained in the materials.

Parameters:

Screw diameter	Φ 20
Length diameter ratio	1:28
Screw speed	0 - 95 rpm frequency control
Screw material	It is made of 38CrMoAl chromium-molybdenum steel. With the surface-layer processing of quenching and tempering, nitriding, chroming, polishing and super-precision grinding, roughness Ra≤0.4μm, nitriding depth≥0.6mm, hardness HRC55~60.
Barrel material	It is made of 45# carbon structural steel. With the surface-layer processing of quenching and tempering, nitriding, chroming, polishing and super-precision grinding, roughness Ra≤0.4μm, nitriding depth≥0.6mm, hardness HRC55~60.
Heating zone	3 zone heaters for barrel, 2 zone heaters for machine head, external covered with safety protective wind hood.
Cooling device	3 groups of multi wing fans with super static forced air cooling.
Drive motor	3.7kw precision gear reduction motor
Power	3∮, AC380V, 50Hz Three-phase and five-line
Dimension	1425×550×940 (W×D×H)mm ( excluding adjustable electric cabinet )
Weight	about 465kg

Features

1. This small film blowing machine has compact design and a small body, not occupying too much indoor area.
2. The host and auxiliary machines are of easy assembly with few raw material. The maximum folded diameter of the thin film can reach200mm.
3. This small film blowing machine is equipped with the C-type fast changing handpiece of easy operation and time & labor-saving test.
4. Single-layer or double-layer cooling vane and the closed-loop control of creasing width ensure reliable product quality.
5. The spiral circulation film blowing die of high performance is easy to clean and maintain.
6. The height of the filming blow tower can be adjusted arbitrarily to meet test requirements.
7. The extrusion, traction and rolling have the property of stepless speed regulating, ensuring requirements of film blowing technology to be met.
