Schlagblech moving device for computer type tricot machine

Abstract

The invention relates to a schlagblech moving device for a computer type tricot machine, which comprises a schlagblech , two wall plates respectively fixed at the left side and the right side of the top of an oil tank of the tricot machine, and a pressing input shaft positioned between the two wall plates, wherein both ends of the pressing input shaft are respectively inserted into holes of the two wall plates and are connected in the mode of rotating pairs; a bracket is fixed on the outer side face of one of the wall plates and is provided with a servo motor and a speed reducer; one end of the pressing input shaft is connected with an output shaft of the speed reducer after extending out of the wall plates; the pressing input shaft drives the schlagblech to move through two same transmission mechanisms which are provided with eccentric wheels and connecting rods; the eccentric wheels are fixed on the pressing input shaft; the upper ends of the connecting rods and the eccentric wheels are connected in the mode of rotating pairs, and the lower ends of the connecting rods and a connecting piece fixed on the schlagblech are connected in the mode of rotating pairs; and the connecting piece is connected with a schlagblech guiding piece fixed on the side wall plate in the mode of rotating pairs. The invention has the advantages of simple structure, convenient regulation and high-speed operation fit.

Description

technical field [0001] The invention relates to a yarn pressing board moving device of a computer type warp knitting machine. Background technique [0002] The warp knitting machine with yarn pressing function realizes the final execution of the yarn pressing movement is the yarn pressing plate, which is driven by the main shaft of the warp knitting machine. The motion form of the yarn pressing plate is a reciprocating linear motion, and there should be a long pause at the highest position. Existing warp knitting machine is that there is a transmission mechanism between the main shaft and the yarn pressing board to convert the continuous rotation of the main shaft into the reciprocating linear motion of the yarn pressing board. Since there is a time coordination requirement between the yarn pressing movement and the knitting movement, the warp knitting machine takes the position of the main shaft rotation angle as the benchmark for the movement position of the whole machine...

AI Technical Summary

Problems solved by technology

In the two above-mentioned yarn pressing devices, the driving force of the yarn pressing plate movement is output by the main shaft, and the movement is transmitted to the yarn pressing plate through the transmission of the flexible member or the connecting rod mechanism. The structure of other parts of the machine interferes and collides, the transmission movement of the flexible parts is unreliable, and the transmission structure of the connecting rod mechanism is complicated, which makes it difficult for the yarn pressing device to be arranged in the whole machine

The transmission mechanism of the yarn pressing plate movement device disclosed in the above two patents controls the size of the yarn pressing stroke and the corresponding relationship between the position of the yarn pressing plate and the spindle angle through a cam mechanism, which is inconvenient to adjust and not suitable for high speed.
