Description

Technical Field

[0001] This utility model relates to the field of yarn feeder technology, and in particular to an intelligent yarn feeder. Background Technology

[0002] When the existing yarn feeder is conveying multiple yarns, it cannot control the stopping of temporarily unused yarns. Single or multiple yarns that have not been used for a long time continue to be conveyed with the yarn feeder, causing the yarn to slack and triggering the edge yarn holder alarm or yarn winding (when winding, the yarn storage cylinder will usually wrap around dozens of times), which greatly affects the knitting efficiency or wastes yarn (when winding). Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an intelligent yarn feeder to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an intelligent yarn feeder includes a housing, on which a yarn clamping device is installed. A yarn-carrying roller is provided on the front side of the yarn clamping device, and the yarn-carrying roller is driven to rotate by a motor installed inside the housing. The yarn clamping device includes a U-shaped mounting frame. Multiple yarn clamping swing block groups are provided on the top of the mounting frame, and each yarn clamping swing block group includes two yarn clamping swing blocks. A yarn clamping swing rod is rotatably connected between the two yarn clamping swing blocks. Multiple electromagnets are fixed on the rear side of the mounting frame, and each electromagnet corresponds to one yarn clamping swing rod. Multiple yarn inlet ceramic eyes are provided on the top of the mounting frame, and multiple yarn outlet ceramic eyes are provided on the bottom of the frame. Each yarn inlet ceramic eye and each yarn outlet ceramic eye corresponds to one yarn clamping swing rod, and each yarn clamping swing rod corresponds to one yarn path.

[0005] Furthermore, a yarn-clamping baffle is installed at the bottom front end of the mounting frame.

[0006] Furthermore, the side wall of the mounting frame is provided with a stop block, and the front side of the stop block is curved.

[0007] Furthermore, the stop block is made of one of the following materials: rubber, polyurethane, nylon, or polytetrafluoroethylene.

[0008] Furthermore, the yarn clamping swing rod includes a fixed column, with a rotating shaft connected to both ends of the fixed column, a connecting rod at the bottom of the fixed column, and a clamp fixed to the bottom of the connecting rod.

[0009] Furthermore, the chuck has a hollow cylindrical structure.

[0010] Furthermore, the chuck is made of a non-magnetic, magnetically conductive material.

[0011] Furthermore, the outer surface of the chuck is provided with a wear-resistant layer.

[0012] Furthermore, the housing is provided with a tension device fixing frame, on which multiple tension devices are installed, each tension device corresponding to a yarn.

[0013] Furthermore, a control circuit board is provided inside the box, and the control circuit board is electrically connected to the electromagnet.

[0014] Beneficial effects

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] The yarn clamping mechanism swings towards the stop block under the action of an electromagnet, conforming to the curved surface of the stop block and forming a clamping force, thus clamping the yarn between the clamp and the stop block. The yarn clamping mechanism's rotational swing achieves yarn clamping, with the clamping action exhibiting an arc-shaped trajectory, resulting in gentler contact with the yarn. This invention controls yarn feeding by controlling the clamping of the yarn at the yarn inlet, preventing excessive yarn feeding that could cause false alarms or yarn tangling on the edge yarn holder, thereby improving knitting efficiency and reducing yarn waste. The yarn clamping mechanism's fixing block is detachably connected to the mounting frame, facilitating the replacement of the clamping mechanism. Attached Figure Description

[0027] See Figures 1-6A smart yarn feeder includes a housing 1, on which a yarn clamping device 7 is installed. The yarn clamping device 7 includes a U-shaped mounting frame 71. The top of the mounting frame 71 is provided with multiple yarn clamping swing block fixing blocks. Each yarn clamping swing block fixing block group includes two yarn clamping swing block fixing blocks 72. A yarn clamping swing rod 73 is rotatably connected between the two yarn clamping swing block fixing blocks 72. Specifically, the opposite sides of the two yarn clamping swing block fixing blocks 72 are respectively provided with shaft holes 721, and the top is provided with threaded holes 720. The mounting frame 71 is threadedly connected to the threaded holes 720 of the yarn clamping swing block fixing blocks 72 by fixing screws 76, thereby fixing the yarn clamping swing block fixing blocks 72 to the mounting frame 71. The yarn clamping lever 73 includes a fixed post 730, with rotating shafts 731 connected to both ends of the fixed post 730. The rotating shafts 731 are rotatably connected to the shaft holes 721 via bearings. A connecting rod 732 is provided at the bottom of the fixed post 730, and a screw hole 7320 is provided at the bottom of the connecting rod 732. A clamp 733 is fixed to the bottom of the connecting rod 732 by adhesive and / or screws. The clamp 733 has a hollow cylindrical structure. The fixed post, rotating shaft, and connecting rod are made of lightweight materials, such as aluminum alloy or magnesium alloy. In this embodiment, the clamp 733 of the yarn clamping lever is made of a non-magnetic, magnetically conductive material, such as pure iron, silicon steel, or ferrite. A wear-resistant layer is provided on the outer surface of the clamp 733, which is a hard chrome plating or nickel plating applied to the outer surface of the clamp by electroplating.

[0028] Multiple electromagnets 79 are fixed to the rear side of the mounting frame 1, each electromagnet 79 corresponding to a yarn clamping swing rod 73; a stop block 78 is provided on the side wall of the mounting frame 1. The front side of the stop block 78 is curved, and this curved surface is adapted to the curved surface of the clamp 733. The stop block 78 is made of one of the following materials: rubber, polyurethane, nylon, and polytetrafluoroethylene. The surface of the stop block 78 is matte or polished. A yarn clamping swing baffle 75 is installed at the bottom front end of the mounting frame 1. An elastic pad is provided on the side of the yarn clamping swing rod 73 near the yarn clamping swing rod 73 to buffer the swing of the yarn clamping swing rod 73.

[0029] The mounting frame 1 has multiple yarn inlet ceramic eyes 74 at its top and multiple yarn outlet ceramic eyes 77 at its bottom. Each yarn inlet ceramic eye 74 and yarn outlet ceramic eye 75 corresponds to a yarn clamping lever 73, and each yarn clamping lever 73 corresponds to one yarn path. A yarn-carrying roller 4 is located at the front of the yarn clamping device. The yarn-carrying roller 7 is driven to rotate by a motor 3 installed inside the housing 1. The housing 1 has a tension device fixing frame 5, on which multiple tension devices 6 are installed. The tension devices 6 are used to detect the tension of the yarn conveyed by the yarn feeder. The tension devices 6 are existing technology. Each tension device 6 corresponds to one yarn path. A control circuit board 2 is installed inside the housing 1. The control circuit board 2 is electrically connected to the electromagnet 19 and the tension devices 6. The control circuit board has a control chip used to receive the yarn tension data detected by the tension devices 6 to control the switching of the electromagnet 79.

[0030] Working Principle: The yarn enters through the inlet eye and exits through the outlet eye, positioned between the clamping device and the stop block. It then winds around the yarn roller and is finally output via a tension device. A motor rotates, driving the yarn roller to move the yarn forward. The tension device detects the yarn tension and transmits the data to a control chip on the control circuit board to monitor the yarn usage. When the yarn tension is abnormal, the control chip activates an electromagnet. Under the electromagnet's action, the clamping device swings towards the stop block, engaging with its curved surface to create a clamping force. The yarn is then clamped between the clamp and the stop block. This controls the yarn feed by controlling the clamping at the inlet end, preventing excessive yarn feed that could cause false alarms or yarn tangling on the edge of the yarn tray, thus improving knitting efficiency and reducing yarn waste. The clamping device's rotating and swinging motion provides a gentler, arc-shaped contact with the yarn.
