Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 、 Figure 2 and Figure 3 The utility model provides an embodiment: a winding device for processing small transformers for household appliances, comprising a support shell 1 for providing support, a driving shaft 2 for driving a fixed shaft 3 to move left and right is arranged inside the support shell 1, a skeleton 4 for rotating and winding a silk thread is arranged near the rear of the driving shaft 2 inside the support shell 1, a fixed shaft 3 for providing support and guidance is arranged on the top of the outer wall of the driving shaft 2, a mounting plate 1 5 for providing support is arranged on the top of the fixed shaft 3, a rolling assembly is arranged on the top of the mounting plate 1 5, and the rolling assembly includes a roller 1 51 and a roller 2 53. After the silk thread passes between the two sets of rollers 1 51 and roller 2 53, the rollers 1 51 and roller 2 53 can rotate as the silk thread moves, thereby reducing friction and improving the quality of silk thread winding.

[0034] Furthermore, the top of the mounting plate 1 5 is slidably connected to a positioning rod 52 supporting roller 2 53, and roller 2 53 is slidably connected to the outer wall of the positioning rod 52. A connecting rod 57 is hinged on the outer side of the top of the mounting plate 1 5. When processing and winding the wire of a small transformer for household appliances, the upper and lower groups of connecting rods 57 cooperate with each other to position roller 2 53 at the center position between mounting plate 1 5 and mounting plate 2 58, so that the wire can be stably positioned in the middle for transportation. The right side of the connecting rod 57 is hinged to a supporting rod 56 and a supporting ring 55 for positioning the positioning frame 54. The inner wall of the support ring 55 is slidably connected to a supporting rod 56 that cooperates with the supporting ring 55 and the connecting rod 57 to position the positioning frame 54 and roller 2 53 at the center position between mounting plate 1 5 and mounting plate 2 58. A limiting component is provided on the front surface of the mounting plate 1 5. The limiting component includes a positioning plate 6 that provides support, and the positioning plate 6 is fixedly connected to the front surface of the mounting plate 1 5.

[0035] Reference Figure 3 、 Figure 4 and Figure 5 The limiting assembly also includes a support block 62 supporting the mounting plate 2 58. The support block 62 is fixedly connected to the front surface of the mounting plate 2 58 near the top of the positioning plate 6. The top of the positioning plate 6 is fixedly connected to a limiting plate 61 that cooperates with the limiting block 66 to slide into the limiting groove 64 to limit the upward movement of the mounting plate 2 58. The left side of the limiting plate 61 is provided with a limiting groove 64 that cooperates with the limiting block 66 to slide into the limiting groove 64 to limit the upward movement direction of the mounting plate 2 58. The right side of the support block 62 is slidably connected to a pull rod 63 that drives the limiting block 66 to move. The left side of the pull rod 63 is fixedly connected to a limiting block 66 that slides into the limiting groove 64 to limit the upward movement direction of the mounting plate 2 58.

[0036] Reference Figure 2 、 Figure 3 and Figure 4 The right side of the support rod 56 is fixedly connected to the right side of the support ring 55 with a positioning frame 54 supporting the second roller 53. The second roller 53 is rotatably connected to the inner wall of the positioning frame 54. The top of the mounting plate 1 5 is close to the top of the positioning frame 54 and a mounting plate 2 58 supporting the first roller 51 is provided. The positioning frame 54 is set to a U shape. The positioning frame 54 is set to a U shape to support the second roller 53. The middle part of the mounting plate 2 58 is rotatably connected to the roller 1 51 that cooperates with the second roller 53 to transmit the silk thread.

[0037] Reference Figure 2 、 Figure 3 and Figure 4, the positioning rod 52 passes through and is slidably connected to the middle of the second mounting plate 58 near the left side of the roller 1 51, and the connecting rod 57 and the roller 1 51 are provided in two groups, and the two groups of connecting rods 57 and the roller 1 51 are symmetrically arranged with the center line of the roller 2 53 as the axis of symmetry, and the other group of roller 1 51 is rotatably connected to the middle of the mounting plate 1 5, and the support rod 56, the positioning frame 54, the support ring 55, the roller 2 53, and the positioning rod 52 are provided in two groups, and the two groups of support rods 56, the positioning frame 54, the support ring 55, the roller 2 53, and the positioning rod 52 are symmetrically arranged with the center line of the mounting plate 1 5 as the axis of symmetry. The arrangement is symmetrical with respect to the axis. When processing and winding the wire of a small transformer for household appliances, the wire can be positioned between the two groups of rollers 1 51 and the two groups of rollers 2 53 by arranging two groups of rollers 1 51 and 53, thereby reducing the contact area with the wire, reducing friction, and improving the winding quality of the wire. At the same time, the two groups of rollers 1 51 and the two groups of rollers 2 53 roll along with the wire transmission, thereby effectively reducing the friction between the wire and the rollers 1 51 and 53, thereby greatly reducing the risk of wear on the wire surface and improving the quality and effect of wire processing.

[0038] Reference Figure 2 、 Figure 3 and Figure 4 The left bottom end of the limit block 66 is set as an inclined surface. When the wire of the small transformer of household appliances is processed and wound, the inclined surface of the limit block 66 can be directly squeezed to make the limit block 66 move outward to cooperate with the squeezing spring 65. After the roller 1 51 contacts the wire, the reverse force of the spring 65 is squeezed to make the limit block 66 reset and slide into the limit groove 64 to position the support block 62 and the mounting plate 2 58 in the upward direction, so that the wire can be supported and stably transmitted in cooperation with multiple groups of rollers 1 51 and rollers 2 53. The limit block 66 slides on the inner wall of the limit groove 64, and the limit block 6 6 is elastically connected to the support block 62 through a spring 65. The left end of the spring 65 is fixedly connected to the right side of the limit block 66. The right end of the spring 65 is fixedly connected to the right side of the inner wall of the support block 62. A pull disc is fixedly connected to the right side of the pull rod 63. When winding the wire of a small transformer for household appliances, the pull disc can be pulled to drive the pull rod 63 and the limit block 66 to move outward to release the limit of the support block 62 and the mounting plate 2 58, so that the distance between the two groups of rollers 2 53 and the two groups of rollers 1 51 can be adjusted, so that it can adapt to the transmission of wires of different thicknesses, thereby improving applicability.

[0039] Furthermore, there are multiple groups of limit grooves 64, and the multiple groups of limit grooves 64 are all opened on the right side of the limit plate 61. The limit plate 61 passes through and is slidably connected to the top of the support block 62. When processing and winding the wire of a small household transformer, by adjusting the position of the mounting plate 2 58 by moving upward, another group of connecting rods 57 and the support ring 55 can be pulled by the mounting plate 2 58 to move. The support ring 55 moves upward and is pulled by the connecting rod 57 at the same time, so that the support ring 55 moves upward and outward at the same time. Through the cooperation of the two groups of connecting rods 57, the support ring 55 can always be positioned at the center position between the mounting plate 1 5 and the mounting plate 2 58, so that the roller 2 53 is also positioned and always positioned at the center position between the mounting plate 1 5 and the mounting plate 2 58. Therefore, when the wire is transmitted, the two groups of rollers 1 51 and roller 2 53 can always be supported at the center position of the outer wall of the wire, thereby improving the stability of the wire transmission and reducing the contact area with the wire, reducing friction, and improving the transmission effect and the quality of the wire.

[0040] Working principle: When in use, first, pass the silk thread through the two sets of rollers 1 51 and roller 2 53 between the mounting plate 1 5 and the mounting plate 2 58. When the silk thread moves, rollers 1 51 and rollers 2 53 will rotate accordingly, thereby reducing friction and improving the quality of silk thread winding. When it is necessary to adjust the distance between rollers 1 51 and rollers 2 53 to adapt to silk threads of different thicknesses, the pull plate is pulled to drive the pull rod 63 and the limit block 66 to move outward, and the limit of the support block 62 and the mounting plate 2 58 can be released. At this time, move the mounting plate 2 58 and roller 1 51 upward and adjust them to the appropriate position. After that, after the silk thread passes between the multiple groups of rollers 1 51 and roller 2 53, loosen the mounting plate 2 58 and move it downward to drive the support block 62 to move. When the limit plate 61 squeezes the inclined surface of the limit block 66, the limit block 66 moves outward and compresses the spring 65. When the roller 1 51 contacts the silk thread, the reverse force of the spring 65 causes the limit block 66 to reset and slide into the limit groove 64, positioning the support block 62 and the mounting plate 2 58 in the upward direction. Therefore, by adjusting the distance between the two groups of rollers 2 53 and the two groups of rollers 1 51, it can adapt to the transmission of silk threads of different thicknesses and improve applicability.

[0041] When the position of the mounting plate 2 58 is moved upward to adjust the position, the mounting plate 2 58 will pull another set of connecting rods 57 and the support ring 55 to move. The support ring 55 is pulled by the connecting rod 57 while moving upward, so that the support ring 55 moves upward and outward at the same time. The cooperation of the two sets of connecting rods 57 always positions the support ring 55 at the center position between the mounting plate 1 5 and the mounting plate 2 58, so that the roller 2 53 is also always positioned at the center position between the mounting plate 1 5 and the mounting plate 2 58. In this way, when the silk thread is transmitted, the two sets of rollers 1 51 and roller 2 53 are always supported at the center position of the outer wall of the silk thread, which improves the stability of the silk thread transmission, reduces the contact area with the silk thread, reduces the friction, and improves the transmission effect and the quality of the silk thread.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
