Non-inertial beating-up mechanism of weaving machine and sley motion method for implementing non-inertial beating-up

Abstract

The invention relates to a non-inertial beating-up mechanism of a weaving machine and a sley motion method for implementing non-inertial beating-up. The beating-up mechanism mainly comprises a geometrically-closed conjugate cam and a swing arm, wherein a roller which is arranged on the swing arm is conjugate with the cam, the rotational motion of the cam enables the swing arm to obtain a rotation angle through the roller, the swing arm is fixedly connected with a beating-up shaft through a beating-up support arm, and an aluminum sley and a steel reed are fixedly arranged on the beating-up support arm; the warp face of fabric passes through the steel reed and forms a cloth fell at a cloth support plate, and the throughout S area of the cloth fell is a non-inertial beating-up area. In the method for implementing the non-inertial beating-up, in the beating-up area, the angular acceleration speed of the sley is in a smaller value of negative acceleration and has reverse direction with the motion of the sley, and the inertia force of the sley at the beating-up area also points to the cloth fell, that is to say, when the sley moves at high speed, the inertia force that points to the cloth fell is smaller than the beating-up resistance once the sley enters into the beating-up area and before the sley reaches the front of the limited beating-up position. The invention has the characteristics of simple structure, convenient and reliable use, improved weaving quality, stable performance, simple and reliable implementation method, and the like.

Description

technical field [0001] The invention relates to a non-inertia conjugate cam beating-up mechanism of a loom and a realization method thereof, belonging to the beating-up mechanism of textile machine weaving equipment. Background technique [0002] The characteristics of traditional inertial beating-up: The characteristics of the sley movement of inertial beating-up are: the angular acceleration of the sley in the beating-up area is at a relatively large negative acceleration and is opposite to the direction of motion of the sley, and the inertial force on the sley points to the weaving fell. The inertial force of the sley overcomes the beating-up resistance of the weaving fell to perform the work of beating-up, and the inertial force is always greater than the beating-up resistance in the beating-up process, so as to ensure the inertial beating-up, the moment of inertia of the sley is equal to the moment of inertia of the sley and The product of angular acceleration. However...

AI Technical Summary

Problems solved by technology

However, when the loom is in the transition process of starting and the speed of the loom has not reached the normal operating speed, the negative acceleration of the slay when entering the beating is smaller than the negative acceleration of the normal operation, and the inertial force generated cannot overcome the beating resistance of the weaving fell, and cannot Inertial beating-up cannot be realized
