Description

Technical Field

[0001] This utility model relates to the technical field of transformer coil processing, specifically to a pressure roller adjustment structure for a transformer coil winding machine. Background Technology

[0002] A rectifier transformer is a power transformer used in rectifier equipment. A rectifier equipment is characterized by an AC input on the primary side and a DC output on the secondary side after passing through rectifier elements. Converter technology encompasses three operating modes: rectification, inversion, and frequency conversion, with rectification being the most widely used. The transformer used as the power supply for a rectifier device is called a rectifier transformer. Most industrial rectified DC power supplies are obtained from the AC power grid through rectifier transformers and rectifier equipment.

[0003] During the winding process of transformers, corresponding equipment is required for assistance. For example, a transformer winding device with existing patent publication number CN221708551U allows users to freely adjust the length of the control wire by using the foot switch through the winding assembly. This allows for adjustments based on actual needs, avoiding problems caused by the control wire being too long or too short, making it more convenient to use.

[0004] However, it is inconvenient to control the winding direction and lacks practicality. Utility Model Content

[0023] Example

[0024] Please see Figure 1-4 A pressure roller adjustment structure for a transformer coil winding machine includes a base frame 1, a reciprocating motor 2, a threaded rod 3, a slider 4, a threaded sleeve 5, an outer frame 6, a first roller 7, a first pressure roller 8, a spring 9, an inner frame 10, a second roller 11, a second pressure roller 12, and a guide rail 20. One side of the base frame 1 is connected to the inner side of the reciprocating motor 2. The output end of the reciprocating motor 2 is connected to one end of the threaded rod 3. The threaded rod 3 is rotatably mounted inside the base frame 1. The bottom end of the base frame 1 is connected to the bottom end of the guide rail 20. The outer side of the guide rail 20 is laterally slidably connected to the bottom side of the slider 4. A threaded sleeve 5 is provided on the inner side of the middle part of the slider 4. The inner wall of the threaded sleeve 5 is screwed to the outer wall of the threaded rod 3. The top end of the slider 4 is connected to the middle of the bottom end of the outer frame 6. A first roller 7 is rotatably mounted on the right side inside the outer frame 6. The outer wall of the first roller 7 is connected to the inner wall of the first pressure roller 8. The outer frame 6 is connected to the middle left side of the inner frame 10 via spring 9. A roller shaft 11 is rotatably installed inside the inner frame 10, and the outer wall of roller shaft 11 is connected to the inner wall of pressure roller 12. The base frame 1 is fixed on one side of the transformer coil winding station. During winding, the wire is placed inside the two sets of pressure rollers 8 and 12. Under the elastic action of spring 9, the inner frame 10 is pushed inward, so that pressure rollers 8 and 12 are in contact with the wire. At the same time as winding, the reciprocating motor 2 runs, causing the threaded rod 3 to rotate. The threaded rod 3 is screwed into the threaded sleeve 5, and the threaded sleeve 5 drives the slider 4 to slide laterally on the outside of the base frame 1, so that the outer frame 6 moves left and right. The roller shaft 7 inside the outer frame 6 drives the pressure roller 8 to rotate, and the roller shaft 11 inside the inner frame 10 drives the pressure roller 12 to rotate, thus constraining the wire laterally.

[0025] It also includes a sliding sleeve 13, a sliding rod 14, and a pull tab 15. The inner side of the left middle of the outer frame 6 is connected to the outer side of the sliding sleeve 13. The inner wall of the sliding sleeve 13 is slidably connected to the outer wall of the sliding rod 14. The outer end of the sliding rod 14 is connected to the middle of the inner end of the pull tab 15. The inner end of the sliding rod 14 is connected to the inner side of the spring 9 in the middle of the outer end of the inner frame 10. By holding the pull tab 15, the sliding rod 14 can be connected to slide outward through the sliding sleeve 13, which drives the inner frame 10 to move outward, separating the pressure roller 8 and the pressure roller 12, facilitating the inner side of the wire and improving convenience.

[0026] It also includes an oil injection nozzle 16. An oil injection nozzle 16 is provided on the left-middle side of the top of the sliding sleeve 13. The output end of the oil injection nozzle 16 is connected to the inner wall of the sliding sleeve 13. Oil can be injected into the inner wall of the sliding sleeve 13 through the oil injection nozzle 16, which is convenient for lubrication and maintenance.

[0027] It also includes an oil filling cap 17, and the outer side of the oil filling nozzle 16 and the inner side of the oil filling cap 17 can be detachably installed; after the oil filling cap 17 is installed on the outer side of the oil filling nozzle 16, the inside of the oil filling nozzle 16 can be sealed and protected, improving reliability.

[0028] It also includes corrugated sleeves 18. The outer sides of the threaded rods 3 on the left and right sides inside the base frame 1 are respectively connected to the outer ends of a set of corrugated sleeves 18. The inner ends of the two sets of corrugated sleeves 18 are respectively connected to the outer sides of the threaded sleeves 5 on the left and right sides of the base frame 1. The two sets of corrugated sleeves 18 can adapt to deformation and always wrap around the outside of the threaded rods 3, providing shielding and protection and improving reliability.

[0029] It also includes an information board 19, with the upper right side of the outer frame 6 connected to the inner side of the information board 19; the information board 19 can display information about the device, making it easier to read and use, and improving convenience.

[0030] In summary, when using a pressure roller adjustment structure for a transformer coil winding machine, the base frame 1 is fixed to one side of the transformer coil winding station. During winding, the sliding rod 14, connected to the gripping pull plate 15, slides outward through the sliding sleeve 13, causing the inner frame 10 to move outward, separating the pressure roller 8 and the pressure roller 12 to facilitate the inner wire feeding. The wire is placed inside the two sets of pressure rollers 8 and 12. Under the elastic action of the spring 9, the inner frame 10 is pushed inward, causing the pressure rollers 8 and 12 to move and fit against the wire. Simultaneously, the reciprocating motor 2 rotates the threaded rod 3, which is screwed into the threaded sleeve 5. The threaded sleeve 5 drives the slider 4 to slide laterally on the outside of the base frame 1, causing the outer frame 6 to move left and right. The inner roller shaft 7 of the outer frame 6 drives the pressure roller 8 to rotate, and the inner roller shaft 11 of the inner frame 10 drives the pressure roller 12 to rotate, thus constraining the line laterally. In addition, the inner wall of the sliding sleeve 13 can be injected with oil through the oil injection nozzle 16 for convenient lubrication and maintenance. After the oil injection cap 17 is installed on the outside of the oil injection nozzle 16, the inside of the oil injection nozzle 16 can be sealed and protected. The two sets of corrugated sleeves 18 can adapt to deformation and always wrap around the outside of the threaded rod 3 to provide shielding and protection. The information board 19 can display the information of the device, which is convenient for reading and assisting in use, thus improving convenience.
