Electronic type hair bulb winding-shaping apparatus

Abstract

The invention discloses a hair bulb winding and shaping device for a roving machine, which comprises a front roller, a traverse bar, and a sliding block fixed with the traverse bar. A hinge of the sliding block is at one end of a connecting rod, a crank link mechanism is connected with a servo motor which is driven by a servo controller driver, the servo controller driver is connected with a frequency converter of a main motor, a shaft of a rotary encoder is concentrically and mechanically connected with the front roller, and the rotary encoder detects change signals of revolution speed of the front big roller and feeds back the change signals to a PLC programmable controller which controls a servo driver and the frequency converter. The device can adjust shaping angles of wool tops through replacing a synchronous pulley in the state of no stopping, has simple machine work, and reduces processing cycle.

Description

technical field [0001] The invention relates to a hair ball winding and forming device for a roving frame, in particular to an electronic hair ball winding and forming device. Background technique [0002] At present, the principle of the wool ball winding device on the roving frame of general wool spinning equipment is that the rotary motion of the winding drum is separated from the reciprocating motion of the wire rod, so that the roving hair ball on the winding drum can only rotate and not reciprocate. . The guide rod completes the reciprocating motion through the variable speed rotary mechanism of the oval gear and the curved slider mechanism. The reciprocating speed of the yarn guide must always be kept constant, so that the winding prisoner hair ball can be kept flat without concave or The drum shape is beneficial to the unwinding of the roving wool balls in the next process and avoids accidental stretching, and the forming angle of the top must be adjusted by changin...

AI Technical Summary

Problems solved by technology

[0003] However, in actual mechanical processing, the number of parts is large, the processing accuracy is high, and the installation accuracy is harsh. Especially the processing of oval gears is difficult to improve the accuracy of existing equipment, and the assembly is cumbersome. In the actual production process, due to The processing accuracy of the elliptical gear often causes the winding hair ball to have a concave or drum shape, which cannot meet the technical requirements and affects the production progress
