[0002] A transformer is composed of multiple large and small components, among which the transformer coil is particularly important. When manufacturing the transformer coil, it needs to be wound and shaped in advance before being installed on the main component of the transformer. After searching, the existing technology (publication number: CN209591796U) records "a transformer coil winding tension control and protection device, including a winding machine and a coil frame. The winding machine side surface is provided with a rotating shaft, and the rotating shaft is symmetrically provided with fixed plates. The fixed plates are open-type structures, and winding blocks are provided between them. The ends of the rotating shaft are rotatably connected with nuts. The coil frame as a whole is a frame structure, and hooks are symmetrically provided on the inner surfaces of both sides. The hooks are provided with hanging rods. The upper surface of the horizontal bar at the bottom of the coil frame is provided with a rope threading block. The rope threading block is connected to the guide block through a connecting rope.

In this application, the winding block is provided between the fixed plates, and the fixed plates can be used to stabilize the winding block, so as to effectively stabilize the coil during the winding process of the transformer coil, thereby achieving the beneficial effects of improving work efficiency, reducing work time, and ensuring product quality."

[0003] Although the transformer coil winding tension control device in the prior art achieves the effect of stabilizing and protecting the coil, it is unable to monitor and adjust in time when the tension changes. Secondly, for the winding of large transformer coils, it is necessary to constantly switch the winding direction to ensure uniform and smooth winding. Utility Model Content

[0004] In order to overcome the defects of the existing technology, a tension control device for the transformer coil winding process is provided to solve the problem that the transformer coil winding tension control device in the existing technology cannot monitor and adjust the tension in time and lacks the winding direction adjustment function.

[0005] To achieve the above-mentioned purpose, a tension control device for a transformer coil winding process is provided, comprising: a crossbeam and an adjustment assembly, wherein the crossbeam is connected between the coil frame and the winding machine, and a pulley tension sensor is installed on the inner side of the crossbeam, and the adjustment assembly is arranged between the crossbeams, and the adjustment assembly comprises a vertical plate connected to the inner side of the crossbeam, and a guide roller is slidably connected to the inner side of the vertical plate, and the vertical plate is provided with a fork assembly on the upper and lower sides of the guide roller, and the fork assembly is slidably connected to the surface of the guide roller.

[0006] Furthermore, the adjustment components are provided in two groups, and the copper wire led out from the coil frame passes through the pulley tension sensor and the two groups of adjustment components in sequence.

[0007] Furthermore, a vertical guide groove is provided inside the vertical plate, and a lifting shaft is slidably connected inside the guide groove, and the lifting shaft is rotatably connected to both ends of the guide roller.

[0008] Furthermore, the front and rear ends of the beam are provided with mounting plates, and electric push rods are installed on the upper and lower ends of the mounting plates, and the piston rod end of the electric push rod is fixedly connected to the connecting block welded to the outer wall of the lifting shaft.

[0009] Furthermore, the fork assembly includes a screw block and an extrusion plate connected thereto, and a slot is provided at one end of the extrusion plate away from the screw block.

[0010] Furthermore, a motor is installed on the outer wall of the vertical plate, and a screw rod is arranged between the vertical plates and parallel to the upper and lower sides of the guide roller, and one end of the screw rod is connected to the motor.

[0011] Furthermore, the screw rod is threadedly connected to the threaded block, and the extrusion plate is clamped to the upper and lower outer walls of the guide roller through the clamping groove.

[0012] The beneficial effects of the present invention are:

[0013] 1. During use, the copper wire passes through the pulley tension sensor to achieve real-time monitoring of the winding process. When the tension is too high, the electric push rod included in the adjustment component pushes the two sets of lifting shafts closer together, so that the guide rollers tend to be in the same horizontal plane, thereby making the copper wire tend to be transmitted and wound on the horizontal plane, which can reduce the tension. Conversely, when the tension is too low, the two sets of guide rollers move away from each other, increasing the tortuosity of the copper wire and increasing the tension, thereby achieving the effect of facilitating tension adjustment.

[0014] 2. During the winding process, by setting the motor, screw and fork assembly on the adjustment assembly close to the winding machine side, the fork assemblies on the upper and lower sides of the guide roller move left and right at the same time, thereby controlling the swing direction of the copper wire inside the two forks, so that uniform and smooth winding can be achieved on the winding machine.

[0020] Reference Figures 1 to 4 As shown, the utility model provides a tension control device for the winding process of a transformer coil, comprising: a crossbeam 1 and an adjustment component 2, the crossbeam 1 being connected between the coil frame 4 and the winding machine 5, and a pulley tension sensor 3 being installed on the inner side of the crossbeam 1, the adjustment component 2 being arranged between the crossbeams 1, and the adjustment component 2 comprising a vertical plate 21 connected to the inner side of the crossbeam 1, and a guide roller 25 being slidably connected to the inner side of the vertical plate 21, the vertical plate 21 and a fork assembly 27 being provided on the upper and lower sides of the guide roller 25, and the fork assembly 27 being slidably connected to the surface of the guide roller 25.

[0021] In this embodiment, the crossbeam 1, the adjustment assembly 2 and the pulley tension sensor 3 constitute the main structure of the tension control device in the transformer coil winding process involved in this application.

[0022] Specifically, the pulley tension sensor 3 is configured as a tension sensor with a three-pulley structure in the prior art, and the copper wire is in a horizontal S-shape and passes through the three pulleys in sequence.

[0023] Specifically, the cross beams 1 are provided in two groups, upper and lower, and each group includes a pair of parallel cross beam 1 structures.

[0024] It should be noted that the threshold of the pulley tension sensor 3 is set by an external controller and is electrically connected to the electric push rod 22 .

[0025] like Figures 1 to 4In the figure, there are two groups of adjustment components 2, and the copper wire led out of the coil frame 4 passes through the pulley tension sensor 3 and the two groups of adjustment components 2 in sequence. A vertical guide groove 211 is opened inside the vertical plate 21, and a lifting shaft 24 is slidably connected inside the guide groove 211, and the lifting shaft 24 is rotatably connected to the two ends of the guide roller 25. The front and rear ends of the beam 1 are provided with mounting plates, and electric push rods 22 are installed at the upper and lower ends of the mounting plate, and the piston rod end of the electric push rod 22 is fixed to the connecting block 23 welded to the outer wall of the lifting shaft 24. Fixed connection, the fork assembly 27 includes a screw block 271 and an extrusion plate 272 connected thereto, and a slot 273 is provided at one end of the extrusion plate 272 away from the screw block 271, a motor 26 is installed on the outer wall of the vertical plate 21, and a screw rod 28 is provided between the vertical plates 21 and parallel to the upper and lower sides of the guide roller 25, and one end of the screw rod 28 is connected to the motor 26, the screw rod 28 is screwed through the screw block 271, and the extrusion plate 272 is clamped on the upper and lower outer walls of the guide roller 25 through the slot 273.

[0026] Specifically, the outer end of the lifting shaft 24 and the piston rod of the electric push rod 22 are in the same vertical plane.

[0027] Specifically, the depth of the slot 273 involved in the fork assembly 27 is greater than the outer diameter of the guide roller 25, so that the guide roller 25 can slide up and down inside the slot 273, and the front and rear inner walls of the slot 273 are slidably connected to the guide roller 25.

[0028] Specifically, the copper wire passes through the upper surface of the first guide roller 25 and the lower surface of the second guide roller 25 while being between the two extrusion plates 272 .

[0029] It should be noted that the axial width of the movement of the two extrusion plates 272 is set by the width of the wound transformer coil.

[0030] During use, the copper wire passes through the pulley tension sensor to achieve real-time monitoring of the winding process. When the tension is too large, the electric push rod included in the adjustment component pushes the two sets of lifting shafts to move closer, so that the guide rollers tend to be in the same horizontal plane, and the copper wire tends to be transmitted and wound in a horizontal plane, which can reduce the tension. On the contrary, when the tension is too small, the two sets of guide rollers move away from each other, so that the curvature of the copper wire is increased, and the tension is increased, thereby achieving the effect of easy tension adjustment. During the winding process, the motor, screw rod and fork assembly are set on the adjustment component close to the side of the winding machine, so that the fork assemblies on the upper and lower sides of the guide roller move left and right at the same time, thereby controlling the swing direction of the copper wire inside the two forks, so that uniform and smooth winding can be achieved on the winding machine.

[0031] The tension control device for the transformer coil winding process of the present invention can effectively solve the problems in the prior art that the transformer coil winding tension control device cannot monitor and adjust the tension in time and lacks the winding direction adjustment function. It is realized on the basis of the existing technology of the tension control device for the transformer coil winding process, and is convenient for the transformer coil winding tension control device to monitor and adjust the tension in time, and to increase the swing direction adjustment function of the wound copper wire.
