Description

Technical Field

[0001] This utility model relates to wrapping wire technology, specifically a paper tape wrapping device for high-temperature resistant and anti-corona wrapping wire for high-voltage motors. Background Technology

[0002] Wrapped wire is an insulated conductor used in motor windings, mainly in large and medium-sized motors and electrical equipment. The precise ratio of its conductor diameter, wrapping film width and thickness, overlap ratio, wrapping pitch and angle directly affects the insulation performance, and the tensile characteristics of the film must be taken into account during engineering design.

[0003] Concentric wrapping machines are specialized equipment in the cable manufacturing industry. They tightly wrap wrapping tape (such as insulating paper, metal foil, fiber tape, etc.) concentrically around the surface of the cable conductor or core, giving the cable insulation, shielding, and mechanical protection functions. Its core working principle is based on a coordinated "rotation + traction" motion: the high-speed rotation of the wrapping head drives the wrapping tape to move in a circular motion around the core, while the traction device pulls the core axially forward at a constant speed. The combination of these two actions causes the wrapping tape to spiral tightly adhere to the core, forming a uniform and continuous wrapping layer.

[0004] The wrapping structure of a concentric wrapping machine consists of a material tray and a roller assembly. The material tray is used to wind the paper tape, and the roller assembly is used to guide the paper tape. However, both the material tray and the roller assembly are arranged on the same side of the material tray seat, which occupies a large area and requires a large material tray seat. Moreover, the existing material trays are generally fixed. When it is necessary to switch to paper tapes of different widths, the entire material tray needs to be removed to replace it with a new size material tray, which is complicated to operate and has poor adaptability. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a paper tape wrapping device for high-voltage motors with high-temperature resistant and anti-corona winding. It features a reasonable layout of the material tray and roller group, improving space utilization, reducing the size of the material tray seat, and allowing for material tray adjustment to accommodate paper tapes of different widths.

[0006] To achieve the above technical objectives, this utility model adopts the following technical solution: a paper tape wrapping device for high-temperature resistant and anti-corona wrapping wire for high-voltage motors, comprising a material tray base, a drive unit and a roller group respectively provided on both sides of the material tray base, the drive unit driving the material tray base and the roller group to rotate, and a plurality of unwinding units provided on all four sides of the material tray base; the unwinding unit includes a rotating shaft, the rotating shaft being rotatably connected to the side wall of the material tray base, an inner material tray fixed in the middle of the rotating shaft, and a threaded part provided at the end of the rotating shaft, the threaded part being threadedly engaged with a pressure plate, the pressure plate facing inward. An outer material tray is fixed to one side of the material tray; the roller assembly includes a mounting base, a fixed base, and several adjustment units. The mounting base is fixed to one side of the turntable base by several connecting rods. The fixed base is fixedly connected to the mounting base by several guide rods.

The two wrapping timing pulleys are respectively sleeved on the output shaft and the main shaft of the wrapping motor. The main shaft is fixed at the center of the material tray seat, and the wrapping timing belt connects the two wrapping timing pulleys.

[0008] Preferably, the material tray seat is equipped with an unwinding motor, and both the output shaft and the rotating shaft of the unwinding motor are fitted with unwinding synchronous pulleys, and the two unwinding synchronous pulleys are connected by an unwinding synchronous belt.

[0028] Example 1:

[0029] like Figure 1 As shown in Figure 2, a paper tape wrapping device for high-temperature resistant and anti-corona wrapping wire for high-voltage motors includes a material tray seat 31. A drive unit and a roller group 4 are respectively provided on both sides of the material tray seat 31. The drive unit drives the material tray seat 31 and the roller group 4 to rotate. Several unwinding units are provided on all four sides of the material tray seat 31.

[0030] The paper tape wrapping device for high-voltage motor high-temperature resistant and anti-corona wrapping wire in this embodiment has a material tray set around the material tray seat 31, and the roller group 4 and the drive unit set on both sides of the material tray seat 31. The layout is reasonable, effectively utilizes the space around the material tray seat 31, reduces the size of the material tray seat 31, and adopts an unwinding unit. The paper tape can be reloaded simply by removing the outer material tray 38. The distance between the outer material tray 38 and the inner material tray 32 can be adjusted, so as to effectively clamp and position paper tapes of different widths.

[0031] like Figure 3 As shown, the unwinding unit includes a rotating shaft, which is rotatably connected to the side wall of the material tray seat 31. An inner material tray 32 is fixed in the middle of the rotating shaft, and a threaded part is provided at the end of the rotating shaft. The threaded part is threadedly engaged with the pressure plate 39. An outer material tray 38 is fixed on the side of the pressure plate 39 facing the inner material tray 32. Rotating the pressure plate 39 can screw in the outer material tray 38, adjust the distance between the outer material tray 38 and the inner material tray 32 to accommodate paper tapes of different widths, or remove the outer material tray 38 to facilitate the replacement of new paper tapes.

[0032] like Figure 4 As shown in Figure 5, the roller assembly 4 includes a mounting base 41, a fixed base 42, and several adjustment units. The mounting base 41 is fixed to one side of the turntable base via several connecting rods. The fixed base 42 is fixedly connected to the mounting base 41 via several guide rods 48. The adjustment units are located between the mounting base 41 and the fixed base 42. The adjustment units include a moving frame 45, an intermediate roller 46, and a wrapping roller 47. The two ends of the moving frame 45 are respectively provided with guide rods 48. The moving frame 45 is provided with a fixed rod. The intermediate roller 46 and the wrapping roller 47 are both provided with clamps on the fixed rods. The clamps are threaded with locking bolts on the side away from the intermediate roller 46 or the wrapping roller 47. The clamps can be adjusted by locking the clamps to lock or release the fixed rods. In this way, the angles of the wrapping roller 47 and the intermediate roller 46 can be adjusted according to the wrapping speed and traction speed, so as to better guide the paper tape through and improve adaptability.

[0033] The drive unit includes a wrapping motor 1, a wrapping timing belt, and two wrapping timing pulleys 2. The two wrapping timing pulleys 2 are respectively mounted on the output shaft and the main shaft of the wrapping motor 1. The main shaft is fixed at the center of the material tray seat 31. The wrapping timing belt connects the two wrapping timing pulleys 2. The wrapping motor 1 drives the wrapping timing pulleys 2 to rotate. Through the transmission of the wrapping timing belt, the two wrapping timing pulleys 2 rotate synchronously, thereby causing the main shaft to drive the material tray seat 31 and the roller group 4 to rotate.

[0034] Through holes are provided at the center of the main shaft, the tray seat 31, the mounting seat 41 and the fixed seat 42. The wire core 6 passes through the through holes in sequence through the main shaft, the tray seat 31, the mounting seat 41 and the fixed seat 42.

[0035] The material tray base 31 is equipped with an unwinding motor 33. The output shaft and rotating shaft of the unwinding motor 33 are both fitted with unwinding synchronous pulleys 35. The two unwinding synchronous pulleys 35 are connected by an unwinding synchronous belt 36. Since the speed of wrapping is relatively fast, the paper tape is subjected to a large tension, which can easily lead to the paper tape breaking. Therefore, an unwinding motor 33 is set up to drive the inner material tray 32 to rotate through the unwinding synchronous pulleys 35 and the unwinding synchronous belt 36, so that the paper tape can be extended quickly and avoid the paper tape breaking due to excessive tension.

[0036] The pressure plate 39 is provided with handles 37 on both sides; the handles 37 make it easy for the operator to rotate the pressure plate 39.

[0037] The turntable base is equipped with a discharge roller 34; the intermediate roller 46 is at the same height as the discharge roller 34; the discharge roller 34 allows the paper tape to be smoothly guided from the inner material tray 32 to the intermediate roller 46, and then guided to the wrapping roller 47 through the intermediate roller 46, thereby completing the wrapping of the wire core 6.

[0038] The mounting base 41 is equipped with an adjusting motor 43. A lead screw 44 is provided between the mounting base 41 and the fixed base 42. The two ends of the lead screw 44 are rotatably connected to the mounting base 41 and the fixed base 42, respectively. The lead screw 44 is threadedly engaged with a nut, and the nut is fixed to the movable frame 45. The adjusting motor 43 drives the lead screw 44 to rotate, which allows the movable frame 45 to move along the guide rod 48, thereby adjusting the distance between the movable frame 45 and the fixed base 42 to adapt to different wrapping speeds and traction speeds.

[0039] A camera 5 is installed above the roller group 4; the camera 5 can capture the effect of the paper tape wrapping the wire core 6, which makes it convenient for operators to test and check the wrapping effect, and facilitates subsequent adjustment of the roller group 4, wrapping speed and traction speed.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
