High-frequency apposition opposite-needling machine

Abstract

The invention discloses a high-frequency apposition opposite-needling machine, comprising a machine frame, a net feeding mechanism, a lower net removing plate, an upper net removing plate, needling mechanisms and a drawing mechanism, wherein the upper needling mechanism comprises two upper transmission shaft components and two upper needle components; the lower needling mechanism comprises two lower transmission shaft components and two lower needle components. The high-frequency apposition opposite-needling machine is characterized in that each of the upper transmission shaft components and the lower transmission shaft components comprises a left half shaft, a right half shaft and a plurality of bent shafts; each bent shaft comprises two shaft heads and a boss which are all connected integrally; each boss is columnar; the center line of each boss is deviated from the axes of the corresponding shaft heads; one bent shaft from the upper transmission shaft components corresponds to one upper lifting transmission mechanism; the upper end of an upper swing arm of the upper lifting transmission mechanism is connected with the boss of the corresponding bent shaft in a sleeving manner; one bent shaft from the lower transmission shaft components corresponds one lower lifting transmission mechanism; the lower end of a lower swing arm of the lower lifting transmission mechanism is connected with the boss of the corresponding bent shaft in the sleeving manner. The high-frequency apposition opposite-needling machine has the advantages that the needling frequency is high, the vibration provoking quantity is smaller, and the production efficiency and product quality are beneficially improved.

Description

technical field [0001] The invention relates to an acupuncture machine, in particular to a high-frequency parallel punching machine. Background technique [0002] Acupuncture is one of the most important processing techniques for nonwovens. There are many types of acupuncture machines, one of which is the iso-punching machine. [0003] The co-located punching machine usually includes a frame, a mesh feeding mechanism, a lower stripping mesh plate, an upper stripping mesh plate, a needle punching mechanism and a pulling mechanism; the upper stripping mesh plate is above the lower stripping mesh plate; the needle punching mechanism includes a needle punching drive device , The upper acupuncture mechanism and the lower acupuncture mechanism, the upper acupuncture mechanism is located above the upper stripping screen plate, and the lower acupuncture mechanism is located below the lower stripping screen plate; Stab at the rear of the mechanism. The gap between the lower strippi...

Problems solved by technology

[0007] However, since the above-mentioned upper transmission shaft assembly and the lower transmission shaft assembly are composed of several eccentric wheels installed on the central shaft, the eccentric wheels are larger in size, their rotating mass is heavier, their reciprocating inertial force is larger, and the amount of vibration aroused is quite large. , so the acupuncture frequency of the acupuncture mechanism is greatly restricted (the highest acupuncture frequency of most acupuncture mechanisms can only reach 1000rnp / min), which restricts the improvement of the quality and production efficiency of nonwovens, and produces more noise
