Technical Field
[0001] This utility model relates to the field of enameled wire production technology, and in particular to a coating roller suitable for flat enameled wires of different specifications. Background Technology
[0002] Flat enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. However, producing products that meet both standard requirements and customer needs is not easy. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires differ, but they all possess four major properties: mechanical, chemical, electrical, and thermal properties.
[0003] In order to reduce friction and protect the insulation layer of the flat enameled wire during the winding process, the enameled wire is coated with lubricating oil after the insulating varnish is applied. The traditional coating process involves immersing the coating roller in lubricating oil and threading the enameled wire through the corresponding coating groove of the coating roller. When the coating roller rotates, the lubricating oil is applied to the flat enameled wire.
[0004] Due to customer needs, flat enameled wires are produced in various specifications. However, the width of the coating grooves on traditional coating rollers is fixed, making it impossible to adapt to the requirements of different specifications of flat enameled wires. Therefore, this application provides a coating roller suitable for flat enameled wires of different specifications to meet these needs. Utility Model Content
[0005] The purpose of this application is to provide a coating roller suitable for flat enameled wires of different specifications, in order to solve the technical problem that the coating grooves on existing coating rollers cannot be adapted to the production needs of flat enameled wires of different specifications.

Each of the plurality of threaded tubes is threaded onto a screw with a rotating handle, and both ends of the screw are rotatably provided with mounting flanges. Each of the adjacent threaded tubes is threaded onto the forward thread section and the reverse thread section of the screw, respectively.
[0008] It also includes a positioning unit for positioning the screw after adjustment.
[0009] Preferably, a plurality of universal balls are arranged in a circular pattern on the inner ring wall where the adjusting ring contacts the roller body and on the outer wall where the driving ring contacts the inner cavity wall of the adjusting ring.
[0010] Preferably, the positioning unit includes a metal plate fixedly mounted on the left mounting flange and a magnetic ring fixedly mounted on the opposite end of the rotating handle and the mounting flange, and the rotating handle is slidably connected to the screw via a slider.

[0024] 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.
[0025] Example: Reference Figure 1 The coating roller shown is suitable for coating flat enameled wires of different specifications. It includes a coating roller with multiple coating grooves arranged side by side on the coating roller. The size of these grooves can be adjusted as needed to accommodate the coating of flat enameled wires of different specifications.
[0026] As a preferred embodiment of this example, Figure 1-3 and Figure 5As shown, the coating roller includes a roller body 1, on which several retaining rings 2 are fixedly sleeved at equal intervals, and two adjusting rings 3 are sleeved between each two adjacent retaining rings 2. An adjusting gap is provided between the two adjusting rings 3, and the distance between the two adjusting rings 3 and the adjacent retaining rings 2 is equal. Each of the several adjusting rings 3 has a limiting block 15 on its inner ring wall, and the lower end of the limiting block 15 is inserted into a movable groove 16 provided on the roller body 1. Each of the several adjusting rings 3 has a rotatable driving ring 4 on its outer wall, and a threaded tube 6 is fixedly installed on the outer wall of each driving ring 4. Each of the several threaded tubes 6 is threaded onto a screw 7 with a rotating handle 10, and both ends of the screw 7 are rotatably provided with mounting flanges 14. Two adjacent threaded tubes 6 are respectively threaded onto the forward thread section and the reverse thread section of the screw 7. The roller also includes a positioning unit for positioning the screw 7 after adjustment.
[0027] The roller body 1 and screw 7 can be installed on the coating machine. The screw 7 is located above the lubricating oil. When dealing with flat enameled wires of different specifications, the rotating handle 10 can be held and rotated to drive the screw 7 to rotate. Through the cooperation with the threaded tube 6, the forward thread section and the reverse thread section, the two adjusting rings 3 located between the retaining rings 2 can move relative to each other or in opposite directions, thereby changing the width of the coating groove (i.e., the accommodating space formed between the retaining ring 2 and the adjacent adjusting ring 3) to adapt to the needs of flat enameled wires of different specifications. After adjustment, the screw 7 can be fixed by the positioning unit to prevent it from rotating. When the roller body 1 rotates, the adjusting rings 3 are driven to rotate together by the limiting block 15, so that the adjusting rings 3 can be immersed in the lubricating oil to facilitate the coating of lubricating oil on the side of the flat enameled wire.
[0028] It should be noted that the length of the limit block 15 is less than the width of the adjusting ring 3.
[0029] As a preferred embodiment of this example, Figure 3 As shown, several universal balls 5 are arranged in a circular pattern on the inner ring wall where the adjusting ring 3 contacts the roller body 1 and on the outer wall where the drive ring 4 contacts the inner cavity wall of the adjusting ring 3.
[0030] The purpose of setting the universal ball bearing 5 is to reduce the friction between the adjusting ring 3 and the roller 1, as well as between the drive ring 4 and the adjusting ring 3, to prevent the generation of friction debris that would affect the quality of the lubricating oil. It also facilitates the adjustment of the coating groove (i.e., the adjusting ring 3 can be moved with a small force).
[0031] As a preferred embodiment of this example, Figure 1 and Figure 4As shown, the positioning unit includes a metal plate 13 fixedly mounted on the left mounting flange 14 and a magnetic ring 12 fixedly mounted on the opposite end of the rotating handle 10 and the mounting flange 14. The rotating handle 10 is slidably connected to the screw 7 via a slider 11. When rotating the screw 7, the rotating handle 10 can be gripped and moved along the extension direction of the screw 7, causing the magnetic ring 12 to be adsorbed and separated from the metal plate 13. At this time, the screw 7 can be rotated. After adjustment, the rotating handle 10 is moved so that the magnetic ring 12 on it contacts the metal plate 13 to form magnetic adsorption fixation, which can effectively prevent the screw 7 from rotating. By using magnetic adsorption fixation, the screw 7 can be fixed in any position, which is beneficial for high-precision adjustment of the coating groove width.
[0032] As a preferred embodiment of this example, Figure 3 As shown, bearings 8 are fixedly sleeved on the mounting shafts of both the screw 7 and the roller body 1, and the two bearings 8 are connected by a connecting plate 9. The purpose of this is to limit the adjustment rings 3 by the screw 7, so as to prevent multiple adjustment rings 3 and the screw 7 as a whole from moving back and forth laterally on the roller body 1 before the coating roller is installed in the coating machine, which would cause serious wear. It is also to avoid the inconsistency between the two adjustment rings 3 and the adjacent retaining rings 2 after installation (which would easily cause the width of the two adjacent coating grooves to be inconsistent after adjustment, which would reduce the number of lines that can be coated at one time).
[0033] As a preferred embodiment of this example, Figure 1 As shown, the length of the movable groove 16 is less than the width of the adjusting ring 3. During the entire adjustment process, the movable groove 16 is blocked by the adjusting ring 3. The purpose is to prevent the movable groove 16 from being partially located in the coating groove, which would prevent the partial surface of the coating groove from contacting the outer surface of the flat enameled wire, thus preventing the outer surface of the flat enameled wire from being coated with lubricating oil.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
