Improved-structure double-shaft needling machine

Abstract

The utility model relates to a structurally improved double-shaft needle loom, which belongs to the technical field of non-woven machinery. Including frame, power transmission mechanism, main shaft, auxiliary shaft and auxiliary shaft transition transmission mechanism, features: auxiliary shaft transition transmission mechanism includes first and second pulleys, transition pulleys, tension pulleys and transmission belts, the first pulley is fixed on the main shaft The end of the second pulley is fixed on the auxiliary shaft, the transition pulley and the tension pulley are set on the frame; the transition pulley is set on the transition pulley shaft seat, and the transition pulley shaft seat is fixed on the frame; the tension pulley is set on On the shaft seat of the tensioning pulley, an adjusting device for the shaft seat of the tensioning pulley is arranged on the frame; a pair of adjusting screw slots are respectively set on the upper and lower parts of the shaft seat of the tensioning pulley, and adjusting screws are arranged at the positions of each adjusting screw slot; The tensioning pulley shaft seat adjusting device comprises a screw nut, a screw seat and a screw rod. Advantages: Avoid noise and improve the environment of the job site.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a double-shaft needling machine with improved structure . 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 sha...

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. After a period of use, the countershaft gears wear out, which not only increases the noise, but also affects the transmission effect. However, it is more troublesome to replace the main and countershaft gears.
