Numerical control fly reed mechanism of towel machine

Abstract

The invention relates to a numerical control fly reed mechanism of a towel machine, comprising an electric control box, a numerical control motor, an origin signal acquisition mechanism, a main signal acquisition mechanism and a fly reed, wherein the origin signal acquisition mechanism is arranged on a shaft or a gear which is synchronous with a rotating shaft of the fly reed; the main signal acquisition mechanism is arranged on a shaft or a gear which is synchronous with a main shaft of the towel machine; the main signal acquisition mechanism generates an electric signal and sends the electric signal to the electric control box to control the numerical control motor to rotate forwardly or reversely so as to drive the fly reed to be opened or closed; and the origin signal acquisition mechanism generates an electric signal and controls the numerical control motor to stop working by the electric control box. The numerical control fly reed mechanism adopts the main signal acquisition mechanism to control the opening and closing of the fly reed and adopts the origin signal acquisition mechanism to control the closing and stationary of the fly reed; and the numerical control motor adjusts a rotating angle of a reed seat, thus being capable of realizing fast or slow weaving of various fur-type or special-type furs, and the wool yarn has good weaving quality. The numerical control fly reed mechanism has simple structure, convenient operation, stable running, low energy consumption, low noise and long service life.

Description

technical field [0001] The invention relates to a movable reed mechanism for a towel machine, in particular to a movable reed mechanism for numerical control fluffing. Background technique [0002] At present, domestic towel machines often use cam rotation to fluff, which is driven by the mechanical selection mechanism through the rack to rotate the rotating gear, thereby driving the rotating cam fixed on the rotating shaft to rotate and transmit to the movable sley to realize the reed stretching and relying on spring force to return The disadvantage of realizing closed reed is: there are many transmission parts, and it is only suitable for low-speed weaving. When the weaving speed is fast, the inertia of the rotating shaft is large. When inching and starting during towel weaving, the requirements for the adjustment of the auxiliary return spring are high. High-speed and low-speed weaving The change of wool height is easy to produce high and short wool phenomenon; the mechan...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the mechanical drive sley opening and closing beating-up in the prior art, the inertia of the rotating shaft is large, the adjustment requirements of the auxiliary return spring are high, the variable range of the reed amount is small, the weaving wool type is few, the weaving quality is poor, or the servo motor is used to drive the movable chest. When the beam and the back beam are beating up, there are many moving parts moving back and forth at the loom, the warp yarns move in a large range, the yarn is easy to break, the energy consumption of the mechanism is high, and the noise is large. Zhang reed, the variable range of the reed amount is large, many wool types can be woven, and the friction coefficient of the warp yarn is small, it is not easy to break the yarn, the rotating shaft has no inertia, the mechanism energy consumption is low, and the noise is low.
