What is the working principle of non-woven needle punching machine?

PET non-woven needle punching machine is the production of non-woven fabrics by needle punching method. It is complete through a mechanical action, that is, the puncturing action of the needle punching machine, to reinforce and cohere the fluffy fiber web to obtain strength.

What to do in the failure analysis of PET non-woven needle punching machine?

First, find out the needle mark produced by the PET non-woven needle punching machine, determine the position where the needle mark is produced, stop to check the needle board puncture condition, and replace the puncture needle at that position. All the needles are replaced and remanufactured to see if there are still needle marks. If there are still needle marks, it is the problem of needle board layout. It is estimated that when the equipment manufacturer allocates the needle board, there is a problem with the needle board needle distribution in the entire production line. If the needle marks are gradually produced, you can adjust each The frequency of acupuncture can be fine-tuned to see if it can break the resonance distribution. If it cannot be solved, only the equipment manufacturer can change the needle plate. This process takes time to explore.

How to measure and calibrate the needle depth of non-woven needle punching machine?

The needle length of each non-woven needle punching machine is different, turn the needle plate to the bottom dead center, and then adjust the bottom needle plate to the zero position of the needle tip when the bottom needle plate is leveled, and then adjust the scale to the indicator The tip of the ruler can be aligned with zero, and the needle penetration depth is how much the bottom needle plate rises in mm. For zero, the gap between the needle tip and the bottom needle plate can be struck by a 5-wire carding machine spacer.

What is the working principle of non-woven needle punching machine?

The non-woven needle punching machine uses the barbed barbs on the edges of the triangular section (or other sections) to repeatedly puncture the fiber web. As the barbs pass through the web, the surface and local inner fibers of the web are forced into the interior of the web. Due to the friction between the fibers, the originally fluffy web is compressed. When the needles exit the web, the pierced fiber bundles break away from the barbs and remain in the web so that many fiber bundles are entangled in the web and can no longer be restored to its original fluffy state. After many times of needling, a considerable number of fiber bundles are stabbed into the fiber web, so that the fibers in the fiber web are entangled with each other, thereby forming a needle-punched nonwoven material with a certain strength and thickness.
