[0002] Currently, magnetic cores made of amorphous materials and nanocrystalline materials are available on the market. Usually, amorphous materials and nanocrystalline materials are rolled into magnetic cores of specific specifications and magnetized to obtain amorphous and nanocrystalline magnetic cores.

[0003] The Chinese utility model with the announcement number CN220085837U records a double-station differential mode winding machine, which includes a frame, on which a first core fixture, a second core fixture, and a core conveying device that shuttles between the two are installed, and the first core fixture and the second core fixture are respectively installed with a wire feeding device, a threading device, and a cycloidal device, and the cycloidal device is located between the first core fixture and the second core fixture, and synchronously performs position change operations on the cores located in the first core fixture and the second core fixture. However, in the process of winding the core with the threading device and the cycloidal device of the equipment, the core is easy to scratch the sheath or insulation coating of the core, and because the fracture of the core after cutting is relatively sharp, it is easy to scratch the operator. Summary of the invention

[0004] In order to solve the problems existing in the above-mentioned prior art, the purpose of the utility model is to provide a magnetic core winding device which is not easy to scratch the magnetic core sheath or insulating coating, and the processed magnetic core is not easy to scratch the operator.

[0005] In order to achieve the above-mentioned first purpose, the magnetic core sheath cutting device provided by the utility model includes a frame, on which a first wire feeding device, a first magnetic core fixing device, a first threading device and a cycloidal device are arranged; the cycloidal device and the first threading device are both arranged close to the first magnetic core fixing device; the frame is also provided with a first tape wrapping device, the first tape wrapping device is located between the wire feeding device and the magnetic core fixing device, the first tape wrapping device includes a material storage mechanism, a tape cutting mechanism and a tape wrapping mechanism, the material storage mechanism includes a first rotating shaft, and the first rotating shaft is provided with tape; the material storage mechanism, the tape cutting mechanism and the tape wrapping mechanism are arranged in sequence along the feeding direction of the tape; the tape cutting mechanism cuts and separates the tape after the tape wrapping mechanism wraps the material with tape.

[0006] As can be seen from the above, the first tape wrapping device is set to wrap the cut tail end of the wire core with tape. Since the front end of the wire core is fixed, this can effectively prevent the first threading device and the cycloid device from wrapping the tail end of the magnetic core with tape during the process of winding the magnetic core, and the magnetic core sheath will not be scratched. At the same time, when carrying out the next step, it is convenient for the operator to take the end wrapped with tape, and it can play a certain identification role, which can reduce the risk of injury to the operator.

[0007] A further solution is that the tape cutting mechanism includes a loading table, a loading table driving member, a pressure roller, a pressure driving member, an ejector, an ejector driving member, a cutting knife and a cutting driving member; the pressure roller, the pressure driving member, the ejector, the ejector driving member, the cutting knife and the cutting driving member are all arranged on the loading table; the loading table driving member drives the loading table to move along the feeding direction; the loading table includes a loading surface, the pressure roller is located above the loading surface, and the pressure driving member drives the pressure roller to approach or move away from the loading surface; a first through hole and a second through hole are provided on the loading table, and the first through hole and the second through hole are arranged along the feeding direction of the tape, the cutting knife is penetrated in the first through hole, and the ejector is penetrated in the second through hole; the ejector driving member drives the ejector to extend out of the first through hole and protrude from the loading surface; the cutting driving member drives the cutting knife to extend out of the second through hole and protrude from the loading surface.

[0008] As can be seen from the above, the pressure roller of the tape mechanism presses the tape, and the ejector lifts up the end of the tape close to the rubber coating mechanism, making it convenient for the rubber coating mechanism to wrap the end of the wire core with tape, and then the cutter extends out to cut off the excess tape, thereby realizing automatic rubber coating without manual operation.

[0013] A further solution is that the tape cutting mechanism also includes a limiting platform, and a wire clamping groove is provided on the limiting platform.

[0014] As can be seen from the above, the wire core is limited by the provided wire clamping groove to prevent the wire core from moving during the operation of the rubber tape wrapping device.

[0015] A further solution is that a accommodating groove is also provided on the limit table, and the extension direction of the accommodating groove is perpendicular to the wire feeding direction of the first wire feeding device; the wire clamping groove is located on the opposite side walls of the accommodating groove; the tape cutting mechanism also includes a wire pressing piece and a wire pressing driving piece, the wire pressing piece is located in the accommodating groove, and the wire pressing driving piece drives the wire pressing piece to move along the extension direction of the accommodating groove.
