Automatic needle loom manufacturers take you to understand the main thorn reinforcement process

The manufacturer of automatic needle loom tells you that the main needling is the needling of the pre-needled web to increase the needle punch density.
main feature:

1. The distance between the stripping plate and the supporting plate is small;
2. The automatic needle loom manufacturer tells you that the frequency of needle loom is high;
3. The acupuncture stroke is small;
4. The needle board has a higher density of needles and shorter needles.
The main acupuncture process comes in many forms:
1. The automatic needle loom manufacturer tells you how many needle plates are counted, including single needle plate, double needle plate and multi-needle plate.
2. According to the acupuncture direction, there are unidirectional acupuncture and counter-needling, and counter-needling can be divided into ectopic counter-needling and homo-location counter-needling, alternate acupuncture and simultaneous acupuncture.
3. Upper thorn; lower thorn;
4. A needling area;
5. Two acupuncture areas.
Needle plate movement direction:
1. The automatic needle loom manufacturer tells you that the movement direction of the needle plate is usually perpendicular to the fiber web, but there are also upward or downward slanting needles. Oblique punching can increase the needling depth. For example, the 60° oblique punching is 13% higher than the vertical needling punching depth. The resulting product has greater strength, lower elongation at break, higher density and lower air permeability. Improve dimensional stability.
2. The automatic needle loom manufacturer tells you that the commonly used inclination angles are 45°, 60°, and 75°.
