Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a tension adjustment device for a winding machine. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). During the operation of the transformer winding machine, tension regulating equipment is typically used to adjust the conductor tension to ensure the stability and controllability of the conductor tension during the winding process, thereby guaranteeing the winding quality and transformer performance.

[0015] 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.

[0016] Please see Figure 1-2 This utility model provides a technical solution: a tension adjustment device for a winding machine, including a slide rail 1, an mounting plate 2 at one end of the slide rail 1, a groove on the slide rail 1, and an elastic plate 4 slidably disposed inside the groove. A guide wheel 5 is rotatably disposed at the lower end of the side of the elastic plate 4 away from the mounting plate 2. A nut seat 6 is installed at the upper end of the side of the slide rail 1 away from the mounting plate 2. An elastic adjustment component for adjusting the elastic plate 4 is installed inside the nut seat 6. The elastic adjustment component can adjust the length of the elastic plate 4 exposed outside the groove, thereby adjusting the deformable length of the elastic plate 4 and adjusting the tension adjustment range to meet the winding requirements at different speeds.

[0017] Furthermore, the mounting plate 2 has evenly distributed mounting holes on its side to facilitate the installation and fixation of the entire device.

[0018] Furthermore, a support plate 3 is provided at the lower end of the side of the slide rail 1 away from the mounting plate 2. The bottom of the support plate 3 is connected to the lower side of the mounting plate 2, which serves to stably support the slide rail 1.

[0019] Furthermore, the elastic adjustment component includes an elastic column 7 threadedly connected inside the nut seat 6. A connecting plate 41 is rotatably provided at the telescopic end of the elastic column 7. The connecting plate 41 is connected to the end of the elastic plate 4 away from the guide wheel 5. When the elastic column 7 is rotated, the elastic column 7 can drive the elastic plate 4 to move inside the slide groove through the connecting plate 41, thereby adjusting the elastic plate 4. When the winding speed of the guide wire increases, the elastic plate 4 can squeeze the elastic column 7 through the connecting plate 41, thereby increasing the length of the elastic plate 4 exposed outside the slide groove. At this time, the degree of bending of the elastic plate 4 increases, thereby preventing the guide wire from being over-tensioned and breaking.

[0020] Furthermore, a handle 71 is provided at the end of the elastic column 7 away from the connecting plate 41 to facilitate the rotation of the elastic column 7.

[0021] The elastic column 7 is a telescopic rod structure with an internal spring. In order to enable the elastic column 7 to be threadedly connected to the nut seat 6, a thread is provided on the side of the fixed end of the elastic column 7.

[0022] When using:

[0023] Rotate the elastic column 7, and the elastic column 7 will drive the elastic plate 4 to move along the slide groove through the connecting plate 41, thereby adjusting the length of the elastic plate 4 exposed outside the slide groove;

[0024] During the transformer winding process, the wire passes through the upper side of the conductor wheel 5 and moves downwards and wraps around the transformer winding core;

[0025] Under normal winding conditions, the wire applies a certain pressure to the elastic plate 4 through the wire wheel 5, causing the elastic plate 4 to bend downward at a certain angle.

[0026] When the winding speed is fast, the elastic plate 4 deforms and bends downward again, thus keeping the wire taut. At the same time, the elastic plate 4 drives the connecting plate 41 to move along the groove, increasing the length of the elastic plate 4 exposed outside the groove, allowing it to deform to a greater extent, thus preventing the wire from breaking due to excessive force. During this process, the connecting plate 41 squeezes the elastic column 7 to shorten it.

[0027] When the winding speed is slow, the elastic plate 4 resets and drives the guide wheel 5 to move upward, thereby keeping the guide in a taut state.

[0028] This invention adopts a mechanical adjustment method without a power source, which can adjust the tension adjustment range according to the winding speed. It has a simple structure, low maintenance cost, can reduce production cost, and is easy to operate and use.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
