Crankcase structure for needling machine

Abstract

The crankcase for needle punching machine as one non-woven fabric making machine has the structure including one case, one main shaft with ends on the case, one pair of first link rods, and one pair of second link rods located in the first pair of link rods, one pair of guide rods, one pair of push rods, and one flywheel on the main shaft. It features one balance weight over the main shaft to slip fit the guide rods. The crankcase in the improved structure can raise the needle punching speed of the needle punching machine for high output.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a crankcase structure of an acupuncture machine. The improvement of the crankcase structure of the engine. Background technique [0002] Due to the relatively simple structure and low cost of single-shaft-driven single-link, single-push-rod, single-needle beam, and single-needle plate needlelooms, it is widely used in non-woven product manufacturers, but this needle The machine also has its own disadvantages, that is, the speed is usually only around 600-800n / min, so the production efficiency is relatively low. [0003] In view of the above, the Chinese Invention Patent Application Publication No. CN1916258A discloses a transmission balance mechanism of an acupuncture machine. It is developed based on the crankcase structure and has a strong pertinence. Since the scheme can make the modified crankcase meet the needling speed of 1200-1500n / min required b...

Problems solved by technology

However, it is difficult or even impossible for this structure to offset the inertial force produced by the complicated motion of the first and second connecting rods 3 and 5, because as known in the industry, the movement of the connecting rods seems to be simple, but in fact it is extremely complicated. As far as this structure is concerned In other words, the big head of the connecting rod (the first and second connecting rods 3, 5, the same below) exhibits circular motion, while the middle part of the connecting rod has both circular motion and up and down motion, and furthermore, the small end of the connecting rod presents a complete Therefore, although the inertial force of the connecting rod is inconspicuous, it is proportional to the square of the speed, so when the speed of the acupuncture machine is greater than 1000n / min, it will seriously cause machine vibration and lateral movement. swing, which is present by the figure 1 The main reason why the crankcase structure of the disclosed single-shaft, single-connecting rod, single push rod, single-needle beam, and single-needle plate needle loom cannot increase the needling speed and affect production capacity
