Abstract
The present disclosure provides a knitting apparatus, including: a frame; a primary yarn guide mounted on the frame; a primary yarn control rod connected to the primary yarn guide; a secondary yarn guide mounted on the frame; a secondary yarn control rod connected to the secondary yarn guide; a needle plate provided at lower ends of the primary yarn guide and the secondary yarn guide; a control cam separately drives the primary yarn control rod to control the primary yarn guide to move, and drives the secondary yarn control rod to control the secondary yarn guide to move; a tension spring connected to the control cam; and an electromagnet. A magnetic force of the electromagnet drives the tension spring to extend and retract, and further drives the control cam to rotate up and down.
