An inclined dragon belt transmission device

Abstract

The invention discloses an inclined dragon belt transmission device, which includes a frame and a dragon belt transmission mechanism. The dragon belt transmission mechanism includes a dragon belt motor, a dragon belt pulley, a dragon belt, a guide wheel and a set of frictional false twist The dragon belt pulleys are set at both ends of the frame respectively and the dragon belts go around the dragon belt pulleys, a set of friction false twist ingots are scattered and attached to the outer surface of the dragon belt between the two pulley pulleys, and the two sets of guide pulleys are clamped separately At the beginning and end of a group of friction false-twisting spindles on the dragon belt, the dragon belt pulleys and guide wheels are inclined towards the outer side of the frame, and the inclination angle is the same as that of the friction false-twisting spindles; The ingot needs to be rotated at an inclined angle. The invention makes the plane of the belt and the vertical plane form the same angle to carry out horizontal circular movement by placing the belt pulley and the guide wheel at an angle. The belt can be driven without turning over during operation. The frictional false twist spindle rotates, eliminating the need for a slanted wheel device. Therefore, when the dragon belt runs at high speed, it runs smoothly and the spindle speed is uniform. It will not cause waste silk, improve the grade of finished silk, and will not damage the dragon belt, effectively prolonging the life of the dragon belt, greatly Increase productivity.

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
