The manufacturer of High speed needle punch carpet Production Line tells you that the acupuncture 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. Among them, the most important is the acupuncture mechanism. The acupuncture nonwoven process forms include: pre-punching, main pricking, pattern needling, ring needling and tubular needling, etc.

The main pricking of the needling machine is to needling the pre-needled web to increase the needling density. the
(1) The manufacturer of High speed needle punch carpet Production Line tells you the main features. The distance between the stripping plate and the supporting plate is small, the needling frequency is high, the needling movement is small, and the needle plate density is high. The needles are shorter.
(2) There are various forms of the main acupuncture process: High speed needle punch carpet Production Line The manufacturer tells you the number of needle boards, there are single needle boards, double needle boards and multi-needle boards. According to the acupuncture direction, there are unidirectional acupuncture and paired needling, and paired needling can be divided into heterotopic needling, homopositional needling, alternate needling and simultaneous needling up.
(3) The movement direction of the needle plate. The manufacturer of High speed needle punch carpet Production Line tells you that the movement direction of the needle board is usually perpendicular to the fiber web, but there are also upward or downward oblique thrusts. Oblique piercing can increase the needling depth. For example, 60° oblique needling is 13% higher than vertical needling depth. The resulting product has greater strength, lower breaking elongation, greater density and less air permeability Improves dimensional stability.
