Description

Technical Field

[0001] This utility model relates to the field of electromagnetic wire production technology, specifically a four-unit winding and wrapping machine. Background Technology

[0002] As a core power conversion device in power systems, industrial equipment, and household appliances, the operating efficiency, safety, stability, and service life of transformers depend primarily on the performance and quality of the internal electromagnetic wire. As a key component of transformer windings, the electromagnetic wire must possess excellent insulation strength, heat resistance, and structural stability. The wrapping process, as the core step in electromagnetic wire processing, directly determines the insulation performance and anti-aging ability of the electromagnetic wire.

[0003] The wrapping reels of existing magnet wire production wrapping machines are mostly fixed with bolts or a single snap-fit ​​structure. When changing wrapping reels of different specifications, the fasteners need to be disassembled one by one, which involves many steps and is time-consuming, thus affecting the wrapping efficiency of magnet wire. Therefore, we have proposed a four-unit wrapping machine to solve the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a four-piece wrapping machine according to an embodiment of the present invention includes a base plate 1, a support base 2 fixed on the top of the base plate 1, a cylinder 3 rotatably connected to the support base 2, four connecting plates 4 fixed on the surface of the cylinder 3, a wrapping tape reel 5 limitedly sleeved on each connecting plate 4, a snap-fit ​​assembly 6 for limiting and fixing the four wrapping tape reels 5 is provided above the base plate 1, and a drive mechanism 7 for driving the cylinder 3 to rotate is installed on the support base 2;

[0031] The snap-fit ​​assembly 6 includes four circular plates 61 disposed above the base plate 1. To enhance the stability of the circular plates 61 when rotating with the connecting plate 4, two telescopic sleeves are fixed between the same circular plate 61 and the connecting plate 4 on one side. However, the telescopic sleeves are not shown in the figure. Four connecting rods 62 are rotatably connected to one side wall of each circular plate 61 through a pin. Four locking blocks 63 adapted to the tape reel 5 are slidably connected to the connecting plate 4. The other end of the connecting rod 62 is rotatably connected to the corresponding locking block 63 through a pin. Four guide rails adapted to the locking blocks 63 are fixed to one side wall of the same connecting plate 4, which can guide and support the locking blocks 63. A push mechanism 64 for driving the four circular plates 61 to move synchronously is installed on the support base 2.

[0032] The working principle and usage process of this utility model: During the use of this four-piece wrapping machine, a support is provided at the front end to support the electromagnetic wire roller, while a winding mechanism is provided at the rear end to wind up the wrapped electromagnetic wire. Before operation, the wrapping tape reels 5, each wrapped with different insulating tapes, are respectively secured to the connecting plate 4. When the electromagnetic wire passes through the cylinder 3, one end of each insulating tape can be fixed sequentially on its surface according to the winding direction of the wrapped electromagnetic wire. Then, starting the drive mechanism 7 will drive the cylinder 3 to rotate. After the cylinder 3 rotates, it will drive the four sets of wrapping tape reels 5 to rotate, and then, in conjunction with the rear winding mechanism, drive the electromagnetic wire to wind up. At this point, it is possible to sequentially stack and wrap different materials of tape around the surface of the electromagnetic wire. When the tape reel 5 needs to be replaced later, the pushing mechanism 64 can be activated to move the four circular plates 61 to one side. After the circular plates 61 move, with the cooperation of the connecting rod 62, the four locking blocks 63 on the same connecting plate 4 can move towards their center position. After the locking blocks 63 move, they will release the restriction on the tape reel 5, and then it can be removed one by one. During installation, after the tape reel 5 is respectively fitted onto the protrusion of the connecting plate 4, the pushing mechanism 64 can be activated again to move the four circular plates 61 to the other side. After the circular plates 61 move, with the cooperation of the connecting rod 62, the four locking blocks 63 on the same connecting plate 4 can move around them. After the locking blocks 63 move, they will limit and fix the tape reel 5, and then the installation of the tape reel 5 can be completed.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the pushing mechanism 64 includes a guide seat 641 fixed to one side wall of the support base 2. An annular seat 642 is slidably connected to the upper limit of the guide seat 641. Two grooves are formed in the guide seat 641, and the annular seat 642 slides inside the two grooves. A movable ring 643 is fixed to one side wall of the annular seat 642. A rotating ring 644 is rotatably connected to the annular groove formed in one side wall of the movable ring 643. The circular plates 61 are all fixedly connected to the rotating ring 644. A one-way cylinder 645 is fixed to one side wall of the guide seat 641. The one-way cylinder 645 ejects... The end slides through the guide seat 641 and is fixedly connected to the annular seat 642. In use, the one-way cylinder 645 with self-locking function can drive the annular seat 642 to move. After the annular seat 642 moves, it will drive the moving ring 643 to move synchronously. Since the rotating ring 644 is limited to rotating on the surface of the moving ring 643, when the top end of the one-way cylinder 645 extends or retracts, it can drive the circular plate 61 to move. Finally, the fixing of the tape reel 5 is completed by the linkage block 63 through the connecting rod 62. Since the rotating ring 644 rotates on the moving ring 643, the circular plate 61 will not be interfered with when it rotates.

[0034] like Figure 3 As shown, in some embodiments, the drive mechanism 7 includes a drive shaft 71 rotatably connected to the side wall of the support base 2 via a bearing. A drive gear 72 is fixed on the surface of the drive shaft 71, and a gear ring 73 is fixed on the surface of the cylinder 3. The gear ring 73 meshes with the drive gear 72. In use, a motor is fixed on one side wall of the support base 2, and the output end of the motor is fixedly connected to one end of the drive shaft 71. After the motor is started, it can drive the drive shaft 71 to rotate. After the drive shaft 71 rotates, it will drive the drive gear 72 on its surface to rotate. After the drive gear 72 rotates, it will drive the gear ring 73 meshing with it to rotate. Therefore, the cylinder 3 can be driven to rotate.

[0035] like Figure 1 , Figure 7 and Figure 8 As shown, in some embodiments, two sets of guide roller assemblies 8 for supporting the wrapped electromagnetic wire are mounted on the top of the base plate 1.

[0036] The guide roller assembly 8 includes a bracket 81 fixed to the top of the base plate 1. A support platform 82 is fixed to the top of the bracket 81. Two transverse rollers 83 are rotatably connected between the inner walls of the two sides of the support platform 82 via bearings. A bidirectional cylinder 84 is fixed to the bottom of the support platform 82. An adjusting plate 85 is fixed to each of the two ejector ends of the bidirectional cylinder 84. The top of the adjusting plate 85 slides through the support platform 82 and extends above it, where a horizontal plate 86 is fixed. The top of the horizontal plate 86 is rotatably connected to two longitudinal rollers 87 via bearings. The two transverse rollers 83 and the two longitudinal rollers 87 are all plastic rollers. The surface of the plastic rollers has a certain elasticity and wear resistance. When the electromagnetic wire comes into contact with the rollers, the plastic material adheres to the surface of the electromagnetic wire through slight deformation, which maintains contact stability and avoids rigid friction. Meanwhile, the plastic material has good insulation properties, which can reduce static electricity generated by friction between the electromagnetic wire and the roller. During use, the two transverse rollers 83 can support the electromagnetic wire during movement. When lateral limiting is required for electromagnetic wires of different shapes or diameters, the bidirectional cylinder 84 with self-locking function can be activated to drive the two adjusting plates 85 to move synchronously in opposite directions. After the two adjusting plates 85 move, the longitudinal rollers 87 on both sides can be adjusted through the transverse plate 86. Therefore, it can be used to guide electromagnetic wires of different shapes and sizes.

[0037] like Figure 3 and Figure 6 As shown, in some embodiments, the protrusions of the connecting plate 4 are provided with strip-shaped limiting grooves 9 in an annular array, and the card holes of the tape reel 5 are fixed with strip-shaped blocks 10 that are adapted to the strip-shaped limiting grooves 9 in an annular array. When the strip-shaped blocks 10 at the card holes of the tape reel 5 are aligned with the strip-shaped limiting grooves 9 of the protrusions of the connecting plate 4 and inserted, the tape reel 5 can be circumferentially limited on the surface of the connecting plate 4, so as to avoid the tape reel 5 slipping on the connecting plate 4 during subsequent rotation, and ensure that the tape output speed is consistent with the rotation speed of the cylinder 3.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
