Numerical control eccentric cam controlled movable fuzzing mechanism

Abstract

The invention relates to a numerical control eccentric cam controlled movable fuzzing mechanism. A drive motor drives an eccentric cam, which is hinged to a drive linkage. The drive linkage is hinged to a travel distribution drive lever, which is hinged to a front drive rod and a rear drive rod. The front drive rod is hinged to a front drive swing arm, which is provided with a moving rod. The rear drive rod is hinged to a rear drive swing arm, which is provided with a tension sensing rod. A reducing mechanism output shaft of the drive motor is provided with an origin signal acquisition mechanism. When the center of circle of the reducing mechanism output shaft, the center of circle of one end of the drive linkage on the eccentric cam and the center of circle of the other end of the drive linkage are on one line and the moving rod on the front drive swing arm is closest to a reed, the moving fuzzing origin position is determined, an electric box drives the drive motor to rotate around the origin position to respectively drive the front and rear drive swing arms through the travel distribution drive lever of the drive linkage and the front and rear drive rods; and under inductive control of a tension sensing mechanism, the warp is driven to move for a certain travel by constant tension.

Description

technical field [0001] The invention relates to a raising mechanism, in particular to a cloth moving raising mechanism controlled by a numerically controlled eccentric cam. Background technique [0002] Raising is a very important process in the finishing of towel fabrics. Using mechanical action to evenly pull out a layer of fluff or long hair on the surface of the fabric, making the fabric bulky and soft, warm and wear-resistant, with concealed weave patterns and soft and beautiful patterns. . The existing raising is divided into two types: reed moving and cloth moving. The traditional reed moving parts have a large structure, high precision requirements, and high weaving costs. However, the traditional cloth moving raising mechanism does not use a rotary drive mechanism with an origin signal mechanism, which is prone to errors. Once A lot of parts will be damaged if mistakes are made, and there are many moving parts, the manufacturing cost is high, the movement adjustmen...

The existing raising is divided into two types: reed moving and cloth moving. The traditional reed moving parts have a large structure, high precision requirements, and high weaving costs. However, the traditional cloth moving raising mechanism does not use a rotary drive mechanism with an origin signal mechanism, which is prone to errors. Once If mistakes are made, many parts will be damaged, and there are many moving parts, the manufacturing cost is high, and the vibration of the moving adjustment operation is large, and the constant tension cannot be controlled when the warp weaving mouth moves back and forth, and the yarn is easy to break
