The non woven spunbond machine is mainly composed of a frame, a net feeding mechanism, a needle punching mechanism, a pulling mechanism, a pattern mechanism, a transmission mechanism, etc., of which the pattern mechanism is only provided by the pattern needle punching machine.
What is the function of non woven spunbond machine?
What is the technological process of non woven spunbond machine?
What are the process characteristics of non woven spunbond machine?
The non woven spunbond machine is a blanket-forming equipment that knits a certain thickness of refractory fiber blanket blanks into refractory fiber blankets through compaction and needle punching. The web is repeatedly punctured with barbed needles having a triangular or other cross-section with barbs on the edges. The fiber web unloaded by the cross-laid or air-laid machine is very fluffy when fed into the needle punching machine, but a certain strength is generated by the cohesion between the fibers, but the strength is very poor. When the needle is pierced into the fiber web, the barbed hook on the needle will drive the fibers on the surface and subsurface of the fiber web to move from the plane direction of the fiber web to the vertical direction of the fiber web, causing the fibers to move up and down, resulting in up and down displacement. The fibers in the fiber web will be squeezed to a certain extent, so that the fibers in the fiber web will be compressed.
The non woven spunbond machine drives the needle beam, the needle plate and the felting needle to reciprocate up and down together through the crank-link mechanism. The fluffy web is fed into the needling zone under the grip of the feed curtain. When the needle plate moves downward, the felting needle penetrates the fiber web, and the fiber web is close to the supporting web plate. When the needle plate moves upward, the friction between the fiber web and the felting needle makes the fiber web and the felting needle move upward together, and the fiber web is close to the stripping plate. The feeding and output speeds are matched, which can be intermittently stepped or continuously moved. After the web passes through the needling area, it has a certain strength, density and thickness before being sent to the main needling.
1. It is suitable for all kinds of fibers, and the original characteristics of the fibers are not affected after mechanical entanglement.
2. Flexible entanglement between fibers, with good dimensional stability and elasticity.
3. It can greatly improve the life of papermaking felt.
4. Good permeability and filtration performance.
5. The terry-shaped product feels plump.
6. No pollution, the leftover material can be recycled.
7. Various geometric patterns or three-dimensional molding products can be manufactured according to requirements.
