Description

Technical Field

[0001] The utility model relates to the technical field of needle selectors, in particular to a rotating shaft type needle selector. Background Art

[0002] Currently, common needle selectors can be divided into electromagnetic and piezoelectric types, which realize needle selection operation through different working principles. Piezoelectric needle selectors use piezoelectric ceramic materials as conversion elements, receive pulse signals sent by the controller, and bend the piezoelectric elements to a pre-memorized shape through the inverse piezoelectric effect of the piezoelectric material to select needles. The electromagnetic needle selector controls the electromagnetic spiral tube to pass current in different directions, causing the polarity of the head end of the electromagnetic spiral tube to change, or is used in conjunction with a permanent magnet, using the attraction and repulsion between the electromagnet and the permanent magnet to swing the needle selection head, that is, the needle selection action of the needle selector is controlled by pressing the needle or directly changing the polarity of the electromagnet, so that the knitting needles are separated into different tracks to complete the needle selection operation.

A slide groove 3 is provided on the top of the bottom shell 1 of the needle selector, and sliders 5 are fixedly connected to the two sides of the bottom of the top cover 2. The sliders 5 correspond to the slide grooves 3, and the sliders 5 are slidably connected to the inside of the slide grooves 3. The slide grooves 3 play the role of limiting the sliders 5. The top cover 2 and the outer side walls of the bottom shell 1 of the needle selector are fixedly connected with mounting plates 4, and screws 6 are provided on the outside of the bottom shell 1 of the needle selector. The top cover 2 is fixedly connected to the bottom shell 1 of the needle selector by screws 6, and the top cover 2 is fixedly connected to the bottom shell 1 of the needle selector by sliders 5. The device is quickly installed on the closed needle selector bottom shell 1, and then quickly fixed by screws 6. A switch interface 11 is fixedly connected to the inside of the needle selector bottom shell 1 on one side. The controller connects the power line to the switch interface 11. Multiple sets of circuit boards 12 are fixedly connected to the inside of the needle selector bottom shell 1. The output end of the circuit board 12 is fixedly connected to a rotating shaft 13. The rotating shaft 13 is then controlled to rotate by the circuit board 12. Multiple sets of rotating shafts 13 are rotatably connected to the inside of the needle selector bottom shell 1. The outer wall of the rotating shaft 13 is fixedly connected to an inclined panel 14. Through the rotation of the rotating shaft 13, The inclined panel 14 will be driven to rotate. A fixed rod 16 is fixedly connected to the inside of the needle selector bottom shell 1, and the outer wall of the fixed rod 16 is rotatably connected to multiple groups of needle selector blades 15.
