Inclined type tangential belt transmission device

Abstract

The invention discloses an inclined type tangential belt transmission device comprising a machine frame and tangential belt transmission mechanisms. Each tangential belt transmission mechanism comprises a tangential belt motor, tangential belt wheels, a tangential belt, guide wheels and a set of friction false twisting spindles, wherein the two tangential belt wheels are arranged at the two ends of the machine frame; the tangential belt passes around the tangential belt wheels; the set of friction false twisting spindles are tightly attached to the surface, between the two tangential belt wheels, of the outer side of the tangential belt in a dispersed mode; the two sets of guide wheels are clamped and installed at the start end and the tail end of the set of friction false twisting spindles on the tangential belt respectively; the tangential belt wheels and the guide wheels incline in the direction of the outer side edge of the machine frame, and the inclined angle is in accord with the inclined angle of the friction false twisting spindles. As the friction false twisting spindles need to incline by a certain angle to rotate, the tangential belt wheels and the guide wheels are arranged in an inclined mode, the same included angle is formed between the plane of each tangential belt and a vertical plane, then horizontal cyclic motion is carried out, the tangential belts can drive the friction false twisting spindles to rotate without being turned over in the operation process, an inclined wheel is removed, and therefore when the tangential belts rotate at a high speed, operation is table, the spindle speed is even, no waste silk is generated, the grade of finished silk is improved, the tangential belts are not damaged, the service life of the tangential belts is prolonged effectively, and production efficiency is improved greatly.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to an elastic yarn machine. Background technique [0002] The chemical fiber stretch yarn machine is a chemical fiber machine that heats and stretches polyester or nylon pre-oriented yarn (POY), and transforms it into a high-strength, low-stretch (or high-stretch) stretch yarn with a certain bulkiness. Machinery is widely used in the subsequent weaving process, and the current spinning speed has reached 1000-1200 m / min. In the texturing spinning process, the speed of the frictional false twist spindle and whether the speed is stable will directly affect the spinning quality. A machine is generally equipped with 216~288 friction false twist ingots. The friction false twist ingots are installed at an angle with the vertical plane of the frame. Its rotation is driven by the dragon belt, which is set on the On the motor spindle pulley, the width direction of the dragon belt moves vert...

AI Technical Summary

Problems solved by technology

Since the rotational speed of the frictional false twist spindle can reach up to 12000 rpm, the linear speed of the dragon belt is about 1000 m / min. In such a high-speed movement, the dragon belt can easily damage the surface during the second turning process through the inclined wheel device. The upper and lower ends of the belt are particularly serious. In severe cases, the dragon belt is damaged and broken, which reduces the service life of the dragon belt

[0003] Since elastic yarn processing is a 24-hour continuous working process, if the belt is damaged or broken, resulting in uneven spindle speed or direct shutdown, it will lead to waste of raw yarn and degradation of finished yarn, and it is cumbersome to replace the belt. The price itself is also very expensive, so it is especially important to extend the service life of the dragon belt
