High-frequency raising needling machine

Abstract

The invention discloses a high-frequency raising needling machine, comprising a machine frame, a feeding mechanism, a brush ring curtain, a net removing plate, a needling mechanism and a drawing mechanism, wherein the needling mechanism comprises a needling driving device, two transmission shaft components and two needle components; the two transmission shaft components are arranged abreast in a front-rear direction; the two needle components are arranged abreast in the front-rear direction; the two transmission shaft components are at the same rotating speed, but are in opposite rotating directions. The high-frequency raising needling machine is characterized in that each transmission shaft component comprises a left half shaft, a right half shaft, and a plurality of bent shafts which are sequentially connected between the left half shaft and the right half shaft; 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 corresponds to a lifting transmission mechanism; the lifting transmission mechanism comprises a swing arm, a push rod and a guiding sleeve; the upper end of the swing arm sleeves the boss of the corresponding bent shaft; the lower end of the swing arm is hinged to the upper end of the push rod; the lower end of the push rod is connected with the corresponding needle component. The high-frequency raising 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 a needling machine, in particular to a high-frequency napping needling machine. Background technique [0002] Needle punching is one of the most important processing techniques for nonwovens. There are many types of needle punching machines, among which the fleece needle punching machine is one of them. [0003] The fleece needling machine usually includes a frame, a feeding mechanism, a brush ring curtain, a stripping board, a needle punching mechanism and a pulling mechanism. The stripping board is above the brush ring curtain, and the needle punching mechanism is located Above, the feeding mechanism is arranged in front of the acupuncture mechanism, and the pulling mechanism is arranged in the rear of the acupuncture mechanism. [0004] The brush ring curtain is the supporting net mechanism of the napping needle loom. Generally, the brush ring curtain includes a ring-shaped brush curtain formed by connecting multiple brushe...

Problems solved by technology

However, since the above-mentioned drive shaft assembly is formed by installing several eccentric wheels on the central shaft, the eccentric wheels are larger in size, heavier in rotating mass, larger in reciprocating inertial force, and quite large in vibration excitation. The needling frequency is greatly restricted (the highest needling frequency of most needling mechanisms can only reach 1000rnp / min), which restricts the improvement of the quality and production efficiency of nonwovens, and the noise generated during work is also relatively large
