Description

Technical Field

[0001] This application relates to the field of paper insertion into the core of a flat wire motor, and more particularly to a paper insertion machine for a flat wire motor core. Background Technology

[0002] Reference Figure 1 The iron core of the flat wire motor is centered around a through hole 11. Several insulating grooves 12 are evenly distributed circumferentially along the inner wall of the through hole 11. The gaps between adjacent insulating grooves 12 form iron core teeth 13 for winding copper wire. Since direct contact between the copper wire and the iron core can lead to insulation failure and affect the motor's operational stability, insulating paper needs to be inserted into the insulating grooves to isolate the copper wire from the iron core and prevent short circuits. The excellent insulation properties of the insulating paper also significantly improve the motor's efficiency and service life, making it a crucial component for ensuring the normal operation of the stator.

[0003] In related technologies, Chinese Patent Publication No. CN223218969U discloses a flat wire motor core paper inserter, including a drive box, a telescopic rod, and a gear ring. The drive box drives the telescopic rod to extend and retract, and one end of the telescopic rod is fixedly connected to an abutment plate. An annular rack is fixedly connected to the inner wall of the gear ring, and a rotating block is fitted onto the top of the gear ring. The rotating block has a conical opening. Workers can place bent insulating paper inside the conical opening, and the abutment plate, driven by a first motor, reciprocates to contact the insulating paper. The conical shape of the opening allows the insulating paper to extend into the core of the flat wire motor within a designated insulating groove, thus completing the paper inserting function.

[0004] Regarding the aforementioned technologies, the inventors believe that when using the flat wire motor core paper inserter, each time the flat wire motor core paper inserter inserts insulating paper into one of the insulating slots, the operator needs to take a new insulating paper, bend it again, and place it inside the conical opening, which is quite cumbersome and has room for improvement. Utility Model Content

[0005] To address the cumbersome process of having to manually remove and re-fold the insulating paper before placing it inside the conical opening whenever the paper inserter for the flat wire motor core inserts the insulating paper into one of the insulating slots, this application provides a paper inserter for the flat wire motor core.

[0006] The paper insertion machine with a flat wire motor core provided in this application adopts the following technical solution: A flat wire motor core paper inserter includes a base, a mounting base rotatably connected to the base, two conveying rollers rotatably connected to the base, a rotary drive for driving the two conveying rollers to rotate relative to each other, a cutter hinged to the base, and a cutting motor for driving the cutter to rotate. The two conveying rollers cooperate to form a gap for inserting insulating paper, and the cutter is disposed between the mounting base and the conveying rollers.

[0007] By adopting the above technical solution, when it is necessary to insert insulating paper into the insulating groove of the iron core, the insulating paper is bent and passed through the gap between the two conveying rollers. The rotating drive drives the two conveying rollers to rotate relative to each other, automatically conveying the insulating paper towards the mounting base. After the insulating paper is inserted into the insulating groove, the cutting motor drives the cutter to rotate and cut the insulating paper. Then the mounting base is rotated so that the insulating paper is aligned with another insulating groove. There is no need for the staff to take out new insulating paper and place it each time, which simplifies the operation process and improves the paper insertion efficiency.

[0008] Optionally, the base includes a base body and a mounting portion integrally connected to the base body and disposed perpendicular to the base body, wherein the mounting portion is provided with a mounting groove for the mounting seat to be partially embedded.

[0009] By adopting the above technical solution, the mounting part of the base provides good support for the mounting seat. The mounting seat is partially embedded in the embedding groove of the mounting part, which enhances the stability of the mounting seat when rotating, reduces the shaking of the mounting seat, and improves the accuracy of the insertion position of the insulating paper.

[0010] Optionally, a gear ring is arranged on one side of the mounting base extending outside the embedding groove, and a drive gear that meshes with the gear ring is rotatably connected to the base body. The base body is also provided with a rotating motor whose output shaft is fixedly connected to the drive gear.

[0011] By adopting the above technical solution, when the rotating motor is working, the output shaft of the rotating motor drives the drive gear to rotate, and the drive gear meshes with the gear ring, thereby driving the mounting base to rotate, realizing the angle adjustment of the iron core, so that the insulating paper can be inserted into different insulating grooves in sequence. The degree of automation is high and the convenience of rotating the mounting base is improved.

[0012] Optionally, the mounting base has a mounting groove for mounting the iron core on the side near the gear ring, and at least two screws extending into the mounting groove are threadedly connected to the mounting base, the screws being spaced apart along the rotational circumference of the mounting base.

[0013] By adopting the above technical solution, after the iron core is placed in the mounting groove, the screw is rotated, and the screw extends into the mounting groove and presses against the iron core, fixing the iron core on the mounting base, thus reducing the probability of the iron core shifting during paper insertion.

[0014] Optionally, the mounting base is provided with an arc-shaped abutment block in the mounting groove that corresponds one-to-one with the screw, and the arc-shaped abutment block is rotatably connected to one end of the screw.

[0015] By adopting the above technical solution, the arc-shaped contact block has a larger contact area with the outer circumference of the iron core, which can more stably press against the iron core and improve the stability of the iron core installed in the mounting base.

[0016] Optionally, the rotary drive includes a drive gear fixedly connected to one of the conveying rollers, a driven gear fixedly connected to the other conveying roller, and a drive motor connected to the output shaft and the drive gear, wherein the drive gear and the driven gear mesh.

[0017] By adopting the above technical solution, when the drive motor is working, the output shaft of the drive motor drives the active gear to rotate. The active gear meshes with the passive gear, and the active gear and the passive gear are respectively fixedly connected to the two conveying rollers, thereby driving the two conveying rollers to rotate relative to each other, thus realizing the function of conveying insulating paper and improving the convenience of driving the conveying rollers to rotate.

[0018] Optionally, it also includes a mounting cylinder fixedly connected to the base, a limiting rod embedded and sliding within the mounting cylinder, and a locking rod threadedly connected to the mounting cylinder. The mounting cylinder is located on the side of the conveying roller near the mounting base. The limiting rod has a tapered opening for the insulating paper to pass through. One end of the locking rod abuts against the limiting rod.

[0019] By adopting the above technical solution, the insulating paper is conveyed by the conveying roller and passes through the conical opening of the limiting rod. The conical opening guides the insulating paper, and the limiting rod slides along the mounting cylinder to adjust its height position, adapting to the paper insertion requirements of iron cores of different sizes, thus improving the versatility and paper insertion accuracy of the paper insertion machine.

[0020] Optionally, it also includes two guide plates fixedly connected to the base. The guide plates are located on the side of the conveying roller away from the mounting base, and the two guide plates are integrally connected on the side of the base, forming a V-shaped guide rail.

[0021] By adopting the above technical solution, the V-shaped guide rail guides the insulating paper before it enters the conveying roller. Utilizing the converging effect of the V-shaped structure, the insulating paper tends to be folded before entering the gap between the two conveying rollers. This eliminates the need for workers to bend the insulating paper before feeding it into the gap between the two conveying rollers, thus improving the convenience of conveying the insulating paper.

[0022] Optionally, a pressure plate is fixedly connected to the side of the guide plate away from the integral connection, and there is a gap between the pressure plate and the guide plate for the insulating paper to pass through.

[0023] By adopting the above technical solution, when the insulating paper passes through the gap between the pressure plate and the guide plate, the pressure plate and the guide plate work together to shape the insulating paper, so that the insulating paper is kept in a bent state and enters the conveying roller, which further improves the convenience of conveying the insulating paper.

[0024] Optionally, the base may be detachably connected to a mounting shaft for mounting a roll of insulating paper on the side away from the mounting seat.

[0025] By adopting the above technical solution, the paper roll of insulating paper is directly installed on the mounting shaft, realizing a continuous supply of insulating paper and improving the automation level of the equipment.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The rotating drive unit drives two conveying rollers to transport insulating paper into the insulating groove, and then the cutter cuts the insulating paper. The rotating mounting base aligns the insulating paper with another insulating groove, eliminating the need for workers to take new insulating paper and place it each time, thus improving the paper insertion efficiency. 2. The rotating motor drives the drive gear to rotate, thereby rotating the mounting base and adjusting the angle of the iron core so that the insulating paper can be inserted into different insulating slots in sequence, which improves the convenience of rotating the mounting base; 3. The insulating paper passes through the tapered opening of the limiting rod, and the limiting rod slides along the mounting cylinder to adjust its height position, adapting to the paper insertion requirements of iron cores of different sizes, thus improving the versatility of the paper insertion machine.
