Double-shaft needling machine

Abstract

The invention discloses a double-shaft needling machine, belonging to the technical field of non-woven textile machinery. The machine comprises a rack, a power transmission mechanism, a main shaft, an auxiliary shaft and an auxiliary shaft transition transmission mechanism. The machine is characterized in that the auxiliary shaft transition transmission mechanism comprises a first belt wheel, a second belt wheel, a transition belt wheel, a tension belt wheel and a transmission belt, wherein the first belt wheel is fixed at the other end part of the main shaft; the second belt wheel is fixed on the auxiliary shaft and corresponds to the first belt wheel; the transition belt wheel and the tension belt wheel are arranged on the rack; the transmission belt is sleeved on the first and second belt wheels, the transition belt wheel and the tension belt wheel; and the transition belt wheel, the tension belt wheel and the first belt wheel are in a triangular positional relation. The double-shaft needling machine disclosed by the invention has the advantages of avoiding noise, reducing the manufacturing and mounting difficulty, being beneficial to maintaining and replacing a bearing, shortening the shutdown time, ensuring the operation efficiency, saving resources and lowering the cost.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a double-axis needle punching machine. Background technique [0002] The so-called double-axis acupuncture machine means that in addition to the main shaft (called the main drive shaft in the industry), it also has a secondary shaft parallel to the main shaft (called the balance shaft in the industry). The acupuncture machine with this structure can meet the requirements of high-speed acupuncture. Improve the output of non-woven fabrics such as non-woven fabrics and non-woven felts per unit time. [0003] The sub-shaft of the double-axis acupuncture machine is rotated by the meshing of the main shaft gear on the main shaft and the counter shaft gear on the sub-shaft, and the main shaft is driven by the power transmission mechanism arranged on the frame. Specifically, as the power transmission mechanism works, it drives the main shaft connected to it and r...

AI Technical Summary

Problems solved by technology

[0004] The biaxial needle loom with the above structure is commonly used by manufacturers of non-woven products at present, but there are the following technical problems: First, the noise is large, which is harmful to on-site work. environment, because the movement of the auxiliary shaft is realized by driving the auxiliary shaft gear fixed on the main shaft through the main shaft gear fixed on the main shaft, and the meshing movement between the main and auxiliary shaft gears will generate serious noise; 1. The secondary shaft gear wears after a period of use, so it not only increases the noise, but also affects the transmission effect. However,
