Description

Technical Field

[0001] The utility model relates to the technical field of coil production, in particular to a tension-adjustable winding machine. Background Art

[0002] A winding machine is a special equipment used to wind coils during the production process of motor rotor coils. It usually consists of a winding frame and a corresponding control system. In the production of motor rotor coils, the winding machine plays a key role. Its main function is to wind the winding wire or coil wire onto the skeleton or core of the rotor coil according to the predetermined winding method and specifications. The winding machine controls parameters such as winding speed, tension and winding direction to ensure uniform distribution and tight bonding of the wire during the coil winding process.

[0003] In the existing winding machines, by controlling the rotation of the rotating frame, the wire between the two pressure regulating wheels can become tighter or looser as the rotating frame rotates, so that the tension of the wire can be adjusted, and then adjustment can be made according to the size requirements of the specific coil, ensuring that the coil is tightly and evenly wound during the winding process, so as to achieve a more precise winding result.

[0004] However, during the actual winding process of the above-mentioned winding machine, due to the lack of a guiding device, the wire will be concentrated in the middle part of the winding roller. When the wire is concentrated in the middle part of the winding roller, the winding tension in this part will increase, while the winding tension on both sides will decrease, which will cause uneven winding tension of the coil and may affect the quality and performance of the coil. In view of this, we propose a winding machine with adjustable tension. Utility Model Content

[0017] Beneficial effects:

[0018] 1. The tension-adjustable winding machine is provided with a bidirectional screw rod, a movable block, and an arc plate. The bottom of the arc plate passes through. Since the middle of the arc plate is higher than the two sides, the wire can be located in the middle of the arc plate, so that the wire is centered and the accuracy of tension adjustment is improved. The movable block reciprocates laterally to evenly arrange the wire on the winding roller, thereby improving the uniformity of the wire tension. At the same time, as the winding roller winds up the wire, the diameter of the winding roller becomes larger and larger. At this time, the electric telescopic rod contracts, so that the movable block also drops synchronously, thereby avoiding changes in the tension of the wire due to the increase in the diameter of the winding roller, and maintaining the consistency of the tension of the winding wire.

The tension of the wire is adjusted by adjusting the position of the pressure regulating roller 10. The top end surface of the mounting seat 1 is fixedly connected with the mounting plate three 11, and the side wall of the mounting plate three 11 is rotatably connected with the winding roller 12. The top end surface of the mounting seat 1 is provided with a guiding device, which includes an electric telescopic rod 13, a connecting piece 14, a bidirectional screw rod 15, a limiting rod 16, a belt 17, a movable block 18, a limiting hole 19, a connecting rod 20, a limiting ring 21, a vertical plate 22, and an arc plate 23.

[0025] In one embodiment of the utility model, the top end surface of the mounting seat 1 is fixedly connected to an electric telescopic rod 13, the electric telescopic rod 13 is fixedly connected to a connecting piece 14, the connecting piece 14 is rotatably connected to a bidirectional screw rod 15, the side wall of the bidirectional screw rod 15 is transmission-connected to a belt 17, the side wall of the rotating shaft 4 is transmission-connected to the belt 17, the rotating shaft 4 rotates through the transmission of the belt 17 to drive the bidirectional screw rod 15 to rotate, the connecting piece 14 is fixedly connected to a limit rod 16, the limit rod 16 is slidably connected to a movable block 18, and the limit rod 16 is fixedly connected to a limit rod 16.

[0026] The wire passes through the winding roller 12 and then passes through the bottom of the arc plate 23. Since the middle of the arc plate 23 is higher than the two sides, the wire can be located in the middle of the arc plate 23, so that the wire is centered. Then the wire passes through the voltage regulating roller 10, and then the wire passes through the limit ring 21 and the limit hole 19, and is wound on the winding roller 5. The drive motor 3 is started to drive the rotating shaft 4 and the winding roller 5 to rotate. The winding roller 5 rotates to rewind the wire.

[0028] In the utility model, when in use, the wire passes through the winding roller 12, and then passes through the bottom of the arc plate 23. Since the arc plate 23 is higher in the middle than the two sides, the wire can be located in the middle of the arc plate 23, so that the wire is centered, and then the wire passes through the voltage regulating roller 10, and then the wire passes through the limit ring 21 and the limit hole 19, and is wound on the winding roller 5. The drive motor 3 is started, driving the rotating shaft 4 and the winding roller 5 to rotate, and the winding roller 5 rotates to reel the wire, and the rotating shaft 4 rotates through the transmission of the belt 17 to drive the bidirectional screw rod 1 5 rotates, thereby causing the movable block 18 to reciprocate laterally, so that the wire is evenly arranged on the winding roller 5. At the same time, as the winding roller 5 winds up the wire, the diameter of the winding roller 5 becomes larger and larger. At this time, the electric telescopic rod 13 contracts, causing the movable block 18 to drop synchronously, so as to maintain the consistency of the tension force of the winding wire. Furthermore, the setting of the arc chamfer can make the wire pass through the limiting hole 19 and the limiting ring 21 more smoothly, reduce resistance and friction, ensure the movement stability and accuracy of the wire, and reduce the risk of damage to the wire.
