High Frequency Alignment Stimulation Machine

Abstract

A high-frequency co-location punching machine, including a frame, a net feeding mechanism, a lower web stripping board, an upper web stripping board, a needling mechanism and a pulling mechanism; the upper needling mechanism includes two upper drive shaft assemblies and two upper The needle assembly, the lower acupuncture mechanism includes two lower transmission shaft assemblies and two lower needle assemblies, and is characterized in that: the upper transmission shaft assembly and the lower transmission shaft assembly each include a left half shaft, a right half shaft and a plurality of crankshafts, The crankshaft includes two shaft heads and a boss integrally connected. The boss is cylindrical and its center line deviates from the axis of the shaft head; one crankshaft in the upper transmission shaft assembly corresponds to an upper lifting transmission mechanism, and the upper shaking in the upper lifting transmission mechanism The upper end of the arm is socketed on the boss of the corresponding crankshaft; one crankshaft in the lower transmission shaft assembly corresponds to a lower lifting transmission mechanism, and the lower end of the lower rocker arm in the lower lifting transmission mechanism is socketed on the boss of the corresponding crankshaft. The invention has high acupuncture frequency and small vibration excitation, which is beneficial to improve production efficiency and product quality.

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
