Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, specifically to a centering and wire-laying machine. Background Technology

[0002] As a core power conversion device in power systems, industrial equipment, and household appliances, the operating efficiency, safety, stability, and service life of transformers depend primarily on the performance and quality of the internal electromagnetic wire. As a key component of transformer windings, the electromagnetic wire must possess excellent insulation strength, heat resistance, and structural stability. During the production and winding process of electromagnetic wire, a wire-laying machine is used to continuously release the coiled electromagnetic wire wound on the reel in a stable and controllable manner.

[0003] However, current wire feeding machines for electromagnetic wires are prone to causing the electromagnetic wires to deviate and sway significantly during feeding, resulting in poor stability and affecting subsequent processing. Furthermore, dust and impurities easily adhere to the surface of the electromagnetic wires. Since the wire feeding machine does not have the function of cleaning the fed electromagnetic wires, it will affect the quality of subsequent winding of the electromagnetic wires. Therefore, we propose a centering wire feeding machine to solve the above problems. Utility Model Content

[0029] 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.

[0030] Example

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the centering and feeding machine proposed in one embodiment of the present invention includes a support base 1, and a support foot is fixed at the bottom of the support base 1, but the support foot is not shown in the figure. The support base 1 is equipped with a drive assembly 2 for driving the electromagnetic wire reel to rotate and feed the wire, an adjustable guide roller assembly 3 for guiding the electromagnetic wire to be fed, and a cleaning assembly 4 for cleaning the surface of the electromagnetic wire to be fed.

[0032] The drive assembly 2 includes a drive shaft 21 rotatably connected to the side wall of the support base 1 via a bearing. A motor is fixed to one side wall of the support base 1, and the output end of the motor is fixedly connected to one end of the drive shaft 21. A drive plate 22 is fixed to one end of the drive shaft 21. A rotating ring 5 is fixed to one side wall of the drive plate 22, which is adapted to the annular groove of the support base 1. The rotating ring 5 can provide auxiliary support and guidance for the drive plate 22, thereby making it more stable during rotation. Placement rods 23 for guiding the electromagnetic coil are fixed in an annular array on one side wall of the drive plate 22. The surface of the placement rods 23 is provided with threaded holes, which can limit and fix the electromagnetic coil after it is placed.

[0033] The adjustable guide roller assembly 3 includes a guide seat 31 fixed to the support seat 1 by two mounting brackets. Two horizontal rollers 32 are rotatably connected between the inner walls of the two sides of the guide seat 31 by bearings. Two bidirectional cylinders 33 are fixed to the bottom of the guide seat 31. The bidirectional cylinders 33 have a self-locking function, so that when the distance between the two adjustment plates 35 is adjusted, it can prevent them from moving on their own. Two moving plates 34 are fixed to the top end of the two bidirectional cylinders 33. The top of each moving plate 34 slides through the guide seat 31 and extends above it and is fixed with an adjustment plate 35. The top of each adjustment plate 35 is rotatably connected with three vertical rollers 36 by bearings.

[0034] The working principle and usage process of this utility model are as follows: In use, the electromagnetic wire reel is adapted to the placement rods 23. After placing the electromagnetic wire reel on the four placement rods 23, it can be locked with bolts. Then, starting the motor drives the drive shaft 21 to rotate. The rotation of the drive shaft 21 drives the drive plate 22 to rotate, which in turn drives the electromagnetic wire reels placed on the four placement rods 23 to rotate. At this time, the wire feeding operation can be realized. The fed electromagnetic wire can be placed on the horizontal rollers 32 and passed through the cleaning component 4, and then connected to the subsequent wrapping machine. When the electromagnetic wire is located on two horizontal rollers 32, the two bidirectional air... The cylinder 33 causes the top ends on both sides to retract simultaneously, which in turn causes the moving plates 34 on both sides to move in opposite directions synchronously. After the two moving plates 34 move, they will drive the adjusting plates 35 to move, and the adjusting plates 35 will drive the vertical rollers 36 on their tops to move. At this time, the vertical rollers 36 on both sides will move towards the middle position, thereby limiting the two sides of the electromagnetic wire after it is unloaded, so as to prevent it from deviating or shaking significantly during the unloading process. When the electromagnetic wire passes through the cleaning component 4, the dust and impurities on its surface can be cleaned by the cleaning component 4. Finally, the cleaned electromagnetic wire will be sent to the wrapping machine.

[0035] like Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, the cleaning assembly 4 includes a bracket 41 fixed on the support base 1. An air blower 42, an air suction cylinder 43, and a filter cylinder 410 are fixed on the bracket 41. To prevent contamination of the electromagnetic wires during air blowing cleaning, a filter structure can be provided at the air inlet pipe of the air blower 42. Furthermore, since the pipe on the cover plate 414 is a flexible hose, there will be no interference when installing or removing the cover plate 414. The top of the filter cylinder 410 is inserted into the cover plate 414, and a cathode magnetic ring 415 is fixed to the top of the filter cylinder 410. An anode magnetic ring 416 is fixed to the bottom of the cover plate 414. The cathode magnetic ring 415 and the anode magnetic ring 416 attract each other. By magnetically fixing the cover plate 414 and the filter cylinder 410, subsequent cleaning... The filter screen 413 is easier to clean. The filter screen 413 is fixed inside the filter cartridge 410. Piston plates 44 are slidably connected inside both the blower 42 and the suction cylinder 43. A reciprocating mechanism 45 for driving the two piston plates 44 up and down is installed on the support base 1. A dust-collecting component 46 is fixed on the bracket 41, and a blower 47 is fixed on the dust-collecting component 46. A U-shaped tube 48 is connected and fixed to the dust-collecting component 46, and a U-shaped tube 49 is connected and fixed to the blower 47. The air outlet pipe of the blower 42 is connected and fixed to the U-shaped tube 49. The air inlet pipe of the suction cylinder 43 is connected and fixed to the air outlet of the filter cartridge 410. The air inlet hose of the filter cartridge 410 is connected and fixed to the U-shaped tube 48. The air inlet pipe of the blower 42 is... An inlet check valve 411 is installed on the inlet pipe of the air inlet cylinder 43, and an outlet check valve 412 is installed on the outlet pipe of the air blower 42 and the outlet pipe of the air inlet cylinder 43. During use, the reciprocating mechanism 45 drives the piston plate 44 inside the air blower 42 and the air inlet cylinder 43 to move up and down. When the piston plate 44 inside the air blower 42 moves up and down, with the cooperation of the inlet check valve 411 on its inlet pipe and the outlet check valve 412 on its outlet pipe, it can draw in outside air into the air blower 42. Then, through the outlet pipe of the air blower 42, the air can be sent to the inside of the U-shaped tube 49, and then through the U-shaped tube 49 to the nozzle of the air blowing component 47 for expulsion. Finally, the air can be expelled. The air is blown onto the surface of the electromagnetic wire, thus separating the dust from the wire. When the piston plate 44 of the suction cylinder 43 moves up and down, the air intake one-way valve 411 on its intake pipe and the air outlet one-way valve 412 on its outlet pipe can draw the cleaned dust into the suction unit 46. Then, the dust-laden airflow is drawn into the filter cartridge 410 through the U-shaped tube 48. After being filtered by the filter screen 413, the dust is trapped inside the filter cartridge 410, while the clean air is drawn into the suction cylinder 43 and finally discharged through the outlet pipe of the suction cylinder 43. By blowing and sucking at the same time, the dust blown during cleaning can be prevented from causing secondary pollution to the electromagnetic wire.

[0036] like Figure 6 and Figure 9 As shown, in some embodiments, the reciprocating mechanism 45 includes two rotating shafts 451 rotatably connected to the support base 1 via bearings. A cam 452 is fixed to one end of each rotating shaft 451, and a connecting rod 457 is fixed between the two cams 452. L-shaped seats 458 are fixed to the inner walls of both sides of the support base 1. The connecting rod 457 is rotatably connected to the two L-shaped seats 458 via bearings, connecting the two cams 452 to ensure that the two rotating shafts 451 and the cams 452 rotate completely synchronously. The L-shaped seats 458 provide auxiliary support for the connecting rod 457, making it more stable during rotation. A connecting rod 453 is movably connected to each cam 452. The top end of one connecting rod 453 is rotatably connected to the piston plate 44 inside the air blower 42 via a pin, and the top end of the other connecting rod 453 is connected to the air intake 43 via a pin. The internal piston plate 44 is rotatably connected. A driven sprocket 454 is fixed on the surface of one of the rotating shafts 451, and a driving sprocket 455 is fixed on the surface of the drive shaft 21. The driven sprocket 454 and the driving sprocket 455 are connected by a chain 456. In use, with the cooperation of the driving sprocket 455, the driven sprocket 454 and the chain 456, when the drive shaft 21 rotates, it can drive one of the rotating shafts 451 to rotate. After the rotating shaft 451 rotates, it will drive the cam 452 to rotate. When the cam 452 rotates, it can drive the connecting rod 453 to move up and down reciprocally. Since the top ends of the two connecting rods 453 are movably connected to the piston plate 44 inside the air blower 42 and the air suction cylinder 43 respectively, the air blowing of the air blower 42 and the air suction of the air suction cylinder 43 can be realized. Furthermore, the drive shaft 21 serves as the power source, so there is no need to set up an additional drive motor, which saves production costs.

[0037] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
