What are the contents of non-woven needle maintenance

Non woven needles are specialized needles used for producing non-woven fabrics. The needle body is formed into a triangular shape, with each edge in a peak shape and 2-3 hooked teeth on its upper hook. The hooks of non-woven needles drive fibers through the fiber mesh material, so it is very important to determine the shape, quantity, arrangement, length, depth, height, and cutting angle of the hooks on the edges of the working section. The commonly used non-woven needles have three hooks on each edge. In some special applications that use bottom fabric materials, the Lu'an Elderly Apartment only has hooks on one or two edges. The bending direction of the handle can be left or right to protect the bottom fabric material longitudinally or transversely, minimizing damage. The direction of the non-woven needle depends on the position of the hooked edge.

The working part of a non-woven needle has a gradual transition from the tip to the top, and its hook also has a gradual transition from small to large from the tip to the end. This design makes it easier for the needle to puncture the fiber mesh. Non woven needles are mainly used in the manufacturing of fabrics with high needle breakage rates, which are mostly made from renewable or natural fibers such as cotton, linen, and jute. But this needle type is not suitable for all situations, as it may be contained on the surface of the fabric, causing relatively large needle holes.

After installation and debugging, the non-woven needle production line must be maintained strictly according to its necessary maintenance procedures while being put into production. The following points need to be achieved:

1. All oil injection points of the equipment must be regularly filled with engine oil, lubricating oil or grease according to their location requirements.

2. Seals (vulnerable parts) must be inspected daily and replaced immediately if damaged.

3. Check the protective panel of the room every day and replace it immediately if it is damaged.

4. Conduct a secondary inspection of the shot blasting machine guard plate, blades, impellers, directional sleeves, and dividing wheels per shift, and replace them immediately if damaged.

5. The electrical system should undergo a secondary inspection.

6. All transmission components are inspected twice a week.

7. The operator should check the cleaning effect at any time, and if there are any abnormalities, stop the machine immediately, connect the reactor in series, and conduct an overall inspection of the equipment.
