Shuttle replacing device of computer flat knitting machine

Abstract

The invention discloses a shuttle replacing device of a computer flat knitting machine, and belongs to knitting machinery. The shuttle replacing device comprises a shuttle replacing frame bottom plate, shuttle replacing frames and motors, first shuttle replacing plates, second shuttle replacing plates, first levers, second levers and a shuttle replacing plate guide plate, wherein a cam is fixed on each motor shaft. The shuttle replacing device is characterized in that the side, facing upwards, of each cam is provided with a first boss, a second boss, a first concave channel and a second concave channel, the first concave channels are located between the two sides of the first bosses, the second concave channels are located between the two sides of the second bosses, first lever rolling wheels are located in the first concave channels, second lever rolling wheels are located in the second concave channels, and the first shuttle replacing plates and the second shuttle replacing plates both act on shuttles; when the first lever rolling wheels are located on the first bosses and the second lever rolling wheels are located on the second concave channels, the second shuttle replacing plates act on the shuttles; when the first lever rolling wheels are located on the first bosses and the second lever rolling wheels are located on the second bosses, the first shuttle replacing plates and the second shuttle replacing plates both do not act on the shuttles; when the first lever rolling wheels are located on the second concave channels and the second lever rolling wheels are located on the second bosses, the first shuttle replacing plates act on the shuttles. Accordingly, the consistency and reliability of the actions are guaranteed, and the shuttle replacing time is short.

Description

technical field [0001] The invention belongs to the technical field of knitting machinery, and in particular relates to a shuttle changing device of a computerized flat knitting machine. Background technique [0002] As known in the industry, the computerized flat knitting machine is equipped with a skybar device and a shuttle changing device. For this, please refer to the "Combining structure of the skybar device and the shuttle changing device of a computerized flat knitting machine" recommended by the invention patent publication number CN104233615A . [0003] And then as known in the industry, because fabrics such as sweaters and knitted garments have a wide variety of designs and colors, there must be yarns of multiple colors or a plurality of yarns to carry out the function of changing weaving. Specifically, when the yarns of different colors are to be replaced according to the weaving process, the shuttle for feeding the yarns of corresponding colors, which is slidab...

Problems solved by technology

[0005] The technical information of the motor shuttle changing device of all computer knitting flat knitting machines can be seen in the disclosed Chinese patent literature, as CN203700691U recommends that "computer knitting flat knitting machine color changing device" and CN203834120U provide "computer knitting flat knitting machine color changing device" ", these two patents have the same effect, but there are the following disadvantages: because there are two shuttle-changing cams, and the two shuttle-changing cams act on two levers (the patent is called "color-changing and warping lever") respectively, so although they can Plays the role of changing the shuttle, but because of the complex structure, it brings troubles to manufacture and assembly, especially because the slopes on the two shuttle changing cams are long, so the time for changing the shuttle is long, which affects the efficiency of yarn changing and knitting
