Abstract

The invention belongs to a needle machine in the technical field of non-woven fabric production machines. In order to resolve technical problems such as great centrifugal force, noise and current loads, the invention provides an internally-eccentric ultra-high speed needle machine. The needle machine comprises a needle beam, a counterweight beam and a crankshaft. The body of the crankshaft is equipped with two first internally-eccentric eccentric parts. The body of the crankshaft is equipped with two second eccentric parts located between the two eccentric parts. The eccentric directions of the first eccentric parts are opposite to those of the second eccentric parts. The top of the needle beam is connected with the first eccentric parts through first opening and closing connecting rods. The top of the counterweight beam is connected with the second eccentric parts through second opening and closing connecting rods. The eccentric parts in two opposite directions on the crankshaft can balance rotary centrifugal force and moment of the crankshaft and can balance reciprocating inertia force and moment of the needle beam and the counterweight beam. When such force and moment reach selfbalance, load of the crankshaft is reduced. When centrifugal force of the crankshaft is on the decrease, the machine operates more stably.

Description

technical field [0001] The invention belongs to the technical field of nonwoven fabric production machinery, and relates to a needling machine. Background technique [0002] Acupuncture non-woven technology is a reinforcement method that uses the puncture effect of a needle to entangle the fibers in the fiber web with a certain degree of uniformity processed by the previous process to form a non-woven fabric with a certain strength and thickness. However, in the actual production of needling reinforcement, the improvement of needling frequency and needling density is affected by the vibration of the equipment's eccentric main shaft and the strength of the main shaft. In order to realize the high-frequency and high-speed operation of the acupuncture machine, the use of counterweights is an effective means to reduce the vibration of the acupuncture machine. Through scientific and reasonable selection, calculation, and processing of counterweights, the reciprocating inertial f...
