Yarn carrier moving device for circular knitting machine

Abstract

The invention discloses a yarn carrier moving device for a circular knitting machine. The yarn carrier moving device comprises a yarn carrier, a shuttle and a square shuttle plate. The yarn carrier is installed on the shuttle, and the shuttle is controlled to drive the yarn carrier to move. The yarn carrier moving device further comprises a torsion mechanism and a back-and-forth displacement mechanism, wherein the torsion mechanism comprises a shuttle base, a torsion spring, an axial position screw, a machine frame and a torsion air cylinder. The machine frame is fixed to the shuttle base through screws, the torsion air cylinder is installed on the machine frame, and a piston rod is arranged in the torsion air cylinder and can abut against a torsion arm of the torsion spring when the piston rod stretches out. The back-and-forth displacement mechanism comprises a hinge pin and a tension spring, wherein the hinge pin is installed between the upper portion of the shuttle and the machine frame and enables the shuttle and the machine frame to be hinged; one end of the tension spring is connected with the bottom of the machine frame, and the other end of the tension spring is connected with the bottom of the shuttle. Through the structure, the yarn carrier can reach a more ideal yarn feeding point in the yarn feeding process, and moving of the yarn carrier can be accurately controlled.

Description

technical field [0001] The invention belongs to the field of knitting machines, in particular to a yarn feeder moving device for a circular knitting machine. Background technique [0002] In the fabric weaving process, the yarn feeder is usually carried by the shuttle to weave, but the conventional shuttle generally only has two working states of full position and half position, so when driving the yarn feeder, it is only a one-dimensional movement, but with the People's pursuit of fashion has also increased the requirements for patterns, which requires the yarn feeder to complete more knitting actions, and it is difficult to meet the requirements for one-dimensional movement at this time. At the same time, the bottom yarn and the colored yarn should be very clear when weaving, that is, the bottom yarn is on the bottom and the colored yarn is on the top, but due to the wrong movement of the yarn feeder, the position of the bottom yarn and the colored yarn is opposite, that i...

Problems solved by technology

[0002] In the fabric weaving process, the yarn feeder is usually carried by the shuttle to weave, but the conventional shuttle generally only has two working states of full position and half position, so when driving the yarn feeder, it is only a one-dimensional movement, but with the People's pursuit of fashion also increases the requirements for patterns, which requires the yarn feeder to be able to complete more knitting actions. At this time, the one-dimensional movement is difficult to meet the requirements.

At the same time, the bottom yarn and the colored yarn should be very clear when weaving, that is, the bottom yarn is on the bottom and the colored yarn is on the top, but due to the wrong movement of the yarn feeder, the position of the bottom yarn and the colored yarn is opposite, that is, the reverse yarn phenomenon occurs. In the prior art, since the yarn feeding point of the yarn feeder cannot be precisely controlled, it cannot be effectively solved
