Numerical control rotating cam control fulcrum chute fuzzing mechanism

Abstract

The invention relates to a numerical control rotating cam and control fulcrum chute fuzzing mechanism. The mechanism consists of a numerical control fuzzing drive mechanism, a fixed stroke reciprocating mechanism and a beating-up slay sword part which is under limiting control through a beating-up drive link and a numerical control fuzzing drive mechanism, wherein an electric box of the numerical control fuzzing drive mechanism drives an eccentric rotating cam through a numerical control motor and a reducing mechanism sequentially, and the eccentric rotating cam carries out drive control on a chute seat with a chute through a push-pull drive mechanism; and one end of the beating-up drive link is hinged with the fixed stroke reciprocating mechanism, the other end of the beating-up drive link is movably hinged to a slay sword, and the beating-up drive link is provided with a sliding block or a rotor which is limited in the chute and slides or rolls along the direction of the chute. A conjugate cam group or a crank changes a linear stroke of the beating-up drive link when the beating-up drive link moves towards the slay sword to a limiting point, so that the slay sword is stabilized, and beating up can be adjusted to beat weft yarns at different positions of a fell; and the mechanism is simple in structure, is convenient to manufacture and use and can be adjusted to meet different fuzz height requirements at any time.

Description

technical field [0001] The invention relates to a weft-beating and raising mechanism of a towel loom, in particular to a numerically controlled rotary cam-controlled fulcrum chute and live reed raising mechanism capable of weaving different wool heights. Background technique [0002] The raising mechanism of the traditional towel machine is divided into the raising of the reed and the raising of the cloth. The raising of the cloth adopts the control of the movable chest beam and the back beam of the loom so that the loom can be moved to complete the raising. The driving energy consumption is high, the yarn friction is large, and the strength requirements are high. It is not easy to synchronize the front and back, and the production efficiency is low; the reed moving fluffing controls the relative displacement of the beating point of the reed to control the height of each weft to achieve fluffing. It has the advantages of small line friction and high production efficiency. ...
