Description

Technical Field

[0001] This utility model relates to winding technology, specifically a paper tape adjustment device for high-temperature resistant and anti-corona winding wires used in 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. The paper must be released from the spool under tension to ensure the paper tape wraps around the core with appropriate force, guaranteeing a certain degree of flexibility in the wrapping wire and preventing wrinkles or breakage of the paper tape.

[0004] However, in actual production, as the paper tape is consumed, the outer diameter of the paper tape becomes smaller and smaller. If the damping torque remains unchanged, the tension of the paper tape will become larger and larger. For the product, the paper tape will become tighter and tighter, which will reduce its flexibility. Moreover, the tension of the paper tape will be unstable when it is released due to the influence of the wrapping speed and the tightness of the paper ring. This will cause wrinkles or breakage when the paper tape is wrapped around the wire. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides a paper tape adjustment device for high-temperature resistant and anti-corona winding wire for high-voltage motors, which can effectively adjust the paper tape tension, ensure the winding wire performance, and prevent paper tape wrinkles or breakage.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: a paper tape adjustment device for high-temperature resistant and anti-corona winding of high-voltage motor, comprising a material tray seat, a drive unit and a roller group respectively provided on both sides of the material tray seat, the drive unit driving the material tray seat and the roller group to rotate, and a plurality of unwinding units provided on all four sides of the material tray seat.

[0007] The unwinding unit includes a rotating shaft and a tension roller. The rotating shaft is rotatably connected to the side wall of the material tray seat. An inner material tray is fixed in the middle of the rotating shaft. The inner material tray contains paper tape. The material tray seat is equipped with an unwinding motor. Both the output shaft of the unwinding motor and the rotating shaft are fitted with unwinding synchronous pulleys. The two unwinding synchronous pulleys are connected by an unwinding synchronous belt. The tension roller is connected to a force sensor through a connecting rod. The force sensor is fixed to the material tray seat. The tension roller is arranged parallel to the rotating shaft. The force sensor is connected to the unwinding motor.

[0008] Preferably, the drive unit includes a wrapping motor, a wrapping timing belt, and two wrapping timing pulleys. 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.

[0009] Preferably, 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 adjustment unit is located between the mounting base and the fixed base.

Changes in paper tape tension cause changes in the angle of the tension roller. The change in the angle of the tension roller is detected by a linkage-driven power sensor, which indirectly obtains the paper tape tension data change and generates a control signal that is transmitted to the unwinding motor. This causes the unwinding motor to adjust the speed of the inner turntable, so that the tension of the paper tape is maintained within the range required for wrapping. Attached Figure Description

[0027] Example 1:

[0028] like Figure 1 As shown in Figure 2, a paper tape adjustment device for high-temperature resistant and anti-corona winding of high-voltage motor 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.

[0029] like Figure 3 As shown in Figure 4, the unwinding unit includes a rotating shaft and a tension roller 34. The rotating shaft 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. The inner material tray 32 is provided with paper tape. The material tray seat 31 is provided with an unwinding motor 33. The output shaft of the unwinding motor 33 and the rotating shaft are both fitted with unwinding synchronous pulleys 35. The two unwinding synchronous pulleys 35 are connected by an unwinding synchronous belt 36. The tension roller 34 is connected to a force sensor 30 through a connecting rod 37. The force sensor 30 is fixed to the material tray seat 31. The tension roller 34 is arranged parallel to the rotating shaft. The force sensor 30 is connected to the unwinding motor 33.

[0030] 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.

[0031] The paper tape is drawn out from the inner feed tray 32, passes through the tension roller 34, the intermediate roller, and the wrapping roller in sequence, and then wraps around the surface of the core 6. As the paper tape is gradually consumed, the outer diameter of the paper tape becomes smaller and smaller, which will cause the tension roller 34 to change angle. At this time, the force sensor 30 detects the angle change of the tension roller 34 and transmits the data to the control module circuit board. The control module indirectly obtains the paper tape tension data change and generates a control signal to transmit to the unwinding motor 33, which controls the unwinding motor 33 to increase the rotation speed of the turntable, so that the paper tape is released quickly, thereby reducing the total tension of the paper tape. When the paper tape tension is low, the control module controls the unwinding motor 33 to reduce the rotation of the inner feed tray 32, so that the paper tape is released slowly, thereby increasing the paper tape tension.

[0032] In this embodiment, the paper tape adjustment device for high-voltage motor high-temperature resistant and anti-corona winding line uses paper tape tension changes to drive tension roller 34 to change angle. The connection rod 37 drives the power sensor 30 to detect the angle change of tension roller 34, indirectly obtaining the paper tape tension data change and generating a control signal to transmit to unwind motor 33. This causes unwind motor 33 to adjust the speed of inner material tray 32, so that the paper tape tension is maintained within the range required for winding.

[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] 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 37. The fixed base 42 is fixedly connected to the mounting base 41 via several guide rods. The adjustment units are located between the mounting base 41 and the fixed base 42. The adjustment units include a movable frame 45, an intermediate roller, and a wrapping roller. The movable frame 45 has guide rods at both ends and a fixed rod. The intermediate roller and the wrapping roller are both mounted on the fixed rods via grippers. The grippers are threaded with locking bolts on the side away from the intermediate roller or the wrapping roller. The grippers can be adjusted by locking the grippers to lock or release the fixed rods. This allows the angles of the wrapping roller and the intermediate roller to be adjusted according to the wrapping speed and traction speed, better guiding the paper tape and improving adaptability.

[0035] 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, thereby adjusting the distance between the movable frame 45 and the fixed base 42 to adapt to different wrapping speeds and traction speeds.

[0036] The end of the rotating shaft is provided with a threaded part, which is threadedly engaged with the pressure plate 39. The pressure plate 39 has an outer material plate 38 fixed on the side facing the inner material plate 32. Both sides of the pressure plate 39 are provided with handles. The threaded part and the pressure plate 39 enable the pressure plate 39 to drive the outer material plate 38 to rotate, adjust the distance between the inner material plate 32 and the outer material plate 38, and adapt to paper tapes of different widths.

[0037] 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.

[0038] 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.
