Technical Field
[0001] The utility model relates to the technical field of high-speed unwinding of metal flat wires and special-shaped wires, in particular to a reverse tension unwinding machine. Background Art
[0002] During the operation of the reverse tension uncoiler, the natural tendency of the material being processed is to unfold and accelerate. Because the diameter of the coil changes as the material unfolds, the linear speed of the material increases, and the volume of metal passing through per unit time must remain equal to ensure the balance and stability of the processing process. When the speed of the wire changes significantly, the material is prone to being over-stretched or squeezed, and the wire will become tangled, broken, or stuck, which will affect subsequent processing and even cause safety accidents.
[0003] Therefore, the utility model provides a reverse tension uncoiler. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the reverse tension uncoiler in the prior art that when the speed of the wire changes greatly during operation, the material is easily over-stretched or squeezed, causing damage to the material and even leading to safety accidents.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a reverse tension uncoiler, comprising an uncoiler body, a support frame fixedly mounted on the surface of the uncoiler body, a support structure provided on the surface of the support frame, the support structure comprising a variable frequency motor, the surface of the variable frequency motor is fixedly connected to the support frame, the internal rotation of the variable frequency motor is connected to a rotating shaft, the rotating shaft passes through the support frame, and an inductor is fixedly mounted on the surface of the support frame.
[0006] The effect achieved by the above components is that by providing the support structure, the stability of wire transportation can be improved during wire transportation.
[0007] Preferably, a bearing is fixedly installed inside the support frame, and the inner wall of the bearing is fixedly connected to the rotating shaft.
[0008] Preferably, the effect achieved by the above components is that the bearing can support the rotation of the shaft
[0009] A cleaning structure is provided on the surface of the support frame, and the cleaning structure includes two rotating rods, both of which are rotatably inserted into the interior of the support frame, a connecting frame is fixedly installed on the surface of the rotating rod, and two mounting frames are fixedly installed on the surfaces of the two connecting frames, and a groove is opened on the surface of the mounting frame, and a brush is slidably connected to the inner wall of the groove.
[0010] The effect achieved by the above components is: by setting up a cleaning structure, the surface of the conveyed wire can be cleaned when the reverse tension uncoiler processes the wire, so that debris will not stick to the processed wire, and the impact of debris on the subsequent use of the wire can be avoided as much as possible.
[0011] Preferably, a control frame is fixedly mounted on the surface of the two brushes.
[0012] The effect achieved by the above components is that the brush can be moved with the help of the control frame.
[0013] Preferably, two fixing brackets are fixedly installed on the surfaces of the two mounting brackets, and the surfaces of the fixing brackets are rotatably connected to a rotating plate.

[0014] The effect achieved by the above components is: when the rotating plate is rotated to a certain angle, the rotating plate is clamped into the inner wall of the clamping hole. At this time, the rotating plate is against the surface of the brush, so that the brush is fixed on the inner wall of the groove.
[0015] Preferably, two balancing racks are fixedly mounted on the surfaces of the two mounting racks, and a support cylinder is rotatably sleeved on the surface of the balancing rack.
[0016] The effect achieved by the above components is that the support tube can support the movement of the wire.
[0017] In summary:
[0018] 1. In the utility model, when the wire is conveyed, the rotating shaft will support the movement of the wire. When the wire feeding is 100kg / min, exceeding or falling below this value, the variable frequency motor will obtain a signal through the sensor, so that the variable frequency motor gives the wire a reverse torque or a positive torque to maintain balance. Conventional wire breakage is related to the inertia of shutdown and startup. When starting and stopping by the variable frequency motor, the speed can be precisely controlled by the inverter, so that the startup and shutdown speed becomes relatively slow, avoiding wire breakage. At the same time, the stable start and stop and conveying reading of the variable frequency motor makes the speed of the wire during unfolding stable, thereby maintaining the diameter size stability to avoid wire jamming caused by different diameters. By setting a support structure, the stability of wire transportation can be improved when conveying the wire.
[0019] 2. In the present invention, when the reverse tension uncoiler processes the wire, the wire will move along the surface of the two brushes. During the movement, the brushes will remove debris on the surface of the wire. By setting a cleaning structure, the surface of the conveyed wire can be cleaned when the reverse tension uncoiler processes the wire, so that debris will not stick to the processed wire, and the subsequent use of the wire can be avoided as much as possible.

[0026] The specific configuration and functions of the support structure 4 and the cleaning structure 3 are described in detail below.
[0027] Reference Figure 3 and Figure 4 As shown, in this embodiment: the support structure 4 includes a variable frequency motor 41, the surface of the variable frequency motor 41 is fixedly connected to the support frame 2, the internal rotation of the variable frequency motor 41 is connected to the rotating shaft 43, the rotating shaft 43 passes through the support frame 2, the surface of the support frame 2 is fixedly installed with a sensor 42, the interior of the support frame 2 is fixedly installed with a bearing 44, the inner wall of the bearing 44 is fixedly connected to the rotating shaft 43, and the bearing 44 can support the rotation of the rotating shaft 43.
[0028] Reference Figure 2As shown, specifically, the cleaning structure 3 includes two rotating rods 302, and the two rotating rods 302 are rotatably inserted into the interior of the supporting frame 2. A connecting frame 303 is fixedly installed on the surface of the rotating rod 302, and two mounting frames 304 are fixedly installed on the surfaces of the two connecting frames 303. A groove 311 is provided on the surface of the mounting frame 304, and a brush 305 is slidably connected to the inner wall of the groove 311. A control frame 306 is fixedly installed on the surface of the two brushes 305, and the brush 305 can be moved with the help of the control frame 306. Two fixing frames 308 are fixedly installed on the surface of the two mounting frames 304, and the surface of the fixing frame 308 is rotatably connected to a rotating plate 309. Two card holes 307 are provided on the surface of the two mounting frames 304, and the inner wall of the card hole 307 is slidably connected to the rotating plate 309. The effect achieved by the above components is: rotate the rotating plate 309, and after the rotating plate 309 rotates a certain angle, the rotating plate 309 is stuck in the inner wall of the clamping hole 307. At this time, the rotating plate 309 is against the surface of the brush 305, so that the brush 305 is fixed on the inner wall of the groove 311. Two balancing frames 310 are fixedly installed on the surface of the two mounting frames 304. The surface of the balancing frame 310 is rotated with a support tube 301, and the support tube 301 can support the movement of the wire.
[0029] Working principle: When conveying wire, the rotating shaft 43 will support the movement of the wire. When the wire feeding rate is 100kg / min, exceeding or falling below this value, the variable frequency motor 41 will obtain a signal through the sensor 42, so that the variable frequency motor 41 will give the wire a reverse torque or a positive torque to maintain balance. By setting the support structure 4, the stability of the wire conveying can be improved when conveying the wire.
[0030] When the reverse tension uncoiler processes the wire, the wire moves along the surface of the two brushes 305. During the movement, the brushes 305 remove debris from the surface of the wire. When the brushes 305 need to be replaced, the rotating plate 309 is rotated. After the rotating plate 309 rotates a certain angle, the rotating plate 309 moves out of the inner wall of the clamping hole 307. At this time, the surface of the rotating plate 309 no longer rests on the brush 305. At this time, the brush 305 can be taken out of the groove 311 with the help of the control frame 306, and then a new brush can be replaced. 305 is placed in the groove 311, and then the rotating plate 309 is rotated. After the rotating plate 309 rotates a certain angle, the rotating plate 309 is stuck in the inner wall of the clamping hole 307. At this time, the rotating plate 309 is against the surface of the brush 305, so that the brush 305 is fixed on the inner wall of the groove 311. By setting the cleaning structure 3, the surface of the conveyed wire can be cleaned when the reverse tension uncoiler processes the wire, so that debris will not stick to the processed wire, and the subsequent use of the wire can be avoided as much as possible.
