[0001] This utility model relates to the field of current transformer processing technology, and in particular to a height detection and marking device for current transformer cores. Background Technology

[0002] In existing technologies, during the initial processing of iron cores, the core heights vary considerably, requiring rough classification to ensure reliability during subsequent finishing processes. Currently, the height of the pre-processed iron cores is typically measured manually, and cores meeting a certain height standard are marked and classified. This method is inefficient and labor-intensive. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a height detection and marking device for current transformer cores. This device can automatically detect the initial processed current transformer cores, determine whether they meet the height standard, and mark them accordingly.

[0004] This utility model discloses a height detection and marking device for a current transformer core, including a frame and rotating rollers disposed at both ends of the frame. A conveyor belt is wound around the rotating rollers. A drive motor is disposed on the frame at one end of one of the rotating rollers, and the drive motor is connected to the corresponding rotating roller. One end of the conveyor belt is the core input end, and the other end of the conveyor belt is the core output end. A horizontal reference plate is disposed above the middle part of the conveyor belt. The two sides of the reference plate are fixed to the frame, and the two ends of the reference plate are inclined downward to fit against the surface of the conveyor belt. A telescopic mechanism is fixed on the frame above the iron core input end of the conveyor belt. The telescopic mechanism is used to push the iron core on the conveyor belt to the reference plate, and then push it forward from the reference plate onto the conveyor belt. A chute is provided on the frame above the middle part of the reference plate. The chute is horizontally arranged along the conveying direction of the conveyor belt. A slider is provided in the chute on both sides. A compression spring is provided in the chute near the iron core output end.

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] Example 1:

[0017] like Figures 1-5As shown, this utility model discloses a height detection and marking device for a current transformer core, including a frame 1 and rotating rollers 2 disposed at both ends of the frame 1. A conveyor belt 3 is wound around the rotating rollers 2. A drive motor 13 is disposed on the frame 1 at one end of one of the rotating rollers 2, and the drive motor 13 is connected to the corresponding rotating roller 2. One end of the conveyor belt 3 is the core input end, and the other end of the conveyor belt 3 is the core output end. A horizontal reference plate 4 is disposed above the middle part of the conveyor belt 3. The two sides of the reference plate 4 are fixed to the frame 1, and the two ends of the reference plate 4 are inclined downward to fit against the surface of the conveyor belt 3. A telescopic mechanism is fixed on the frame 1 above the iron core input end of the conveyor belt 3. The telescopic mechanism is used to push the iron core on the conveyor belt 3 to the reference plate 4, and then push it forward from the reference plate 4 to the conveyor belt 3. A slide groove 7 is provided on the frame 1 above the middle part of the reference plate 4. The slide groove 7 is horizontally arranged along the conveying direction of the conveyor belt 3. A slider 15 is provided in the slide groove 7 on both sides. A compression spring 17 is provided in the slide groove 7 near the iron core output end. The two ends of the compression spring 17 are respectively connected to the slider 15 and the end of the slide groove 7 on the side of the iron core output end. A horizontal marker rod 6 is provided between the two sliders 15.

[0018] The marking rod 6 has a hollow interior, forming an ink-receiving cavity. A long strip marking groove 8 is provided on the side of the marking rod 6 facing the input end of the iron core. The marking groove 8 is connected to the ink-receiving cavity. The distance between the marking groove 8 and the reference plate 4 is the height of the standard current transformer core. An air pressure balance hole 19 is provided at the top of the marking rod 6.

[0019] The frame 1 serves as the mounting carrier for all components, and its specific structure is not limited. Two rotating rollers 2 are rotatably mounted on the frame 1. One of the rotating rollers 2 is connected to a drive motor 13, which drives the rotating roller 2 to rotate, thereby driving the conveyor belt 3 mounted on the rotating roller 2. To ensure stable operation of the conveyor belt 3 and provide stable support for its iron core, a support plate is provided on the lower surface of the upper conveyor belt 3. The support plate supports the conveyor belt 3. The two ends of the reference plate 4 are inclined downwards and fit against the conveyor belt 3. The two ends refer to the front and rear ends of the conveyor belt 3 in the conveying direction. The downward inclination of the two ends of the reference plate 4 facilitates the pushing of the iron core from the conveyor belt 3 onto the reference plate 4, and allows it to slide smoothly from the reference plate 4 onto the conveyor belt 3. Throughout the process, the telescopic mechanism drives the iron core on the conveyor belt 3 to move from the conveyor belt 3 to the reference plate 4, and then from the reference plate 4 forward onto the conveyor belt. A certain thrust is maintained throughout the entire process. When the height of the iron core reaches a certain standard, the upper end of the iron core contacts the marking rod 6, and the marking groove 8 on the marking rod 6 touches the iron core, causing the ink in the marking groove 8 to make a mark on the iron core, indicating that the height of the iron core is greater than the standard value. When the iron core contacts the marking rod 6, the telescopic mechanism continues to push the iron core, which in turn pushes the marking rod 6 forward. The sliders 15 at both ends of the marking rod 6 overcome the pressure of the compression spring 17 and move within the slide groove 7. Of course, under normal circumstances, the height of the largest initial-processed iron core should also be less than the distance between the marking rod 6 and the conveyor belt 3. Therefore, when the telescopic mechanism continues to push the iron core from the reference plate 4 to the conveyor belt 3, the upper end of the iron core will inevitably detach from the marking rod 6, and the marking rod 6 will return to the middle part of the reference plate 4 under the action of the compression spring 17, so that the next iron core can be marked for inspection.

[0020] To make the slider 15 move more stably in the slide groove 7, a guide rod 18 can be placed horizontally in the slide groove 7, and a guide hole is provided on the slider 15 accordingly. The slider 15 and the guide rod 18 cooperate to slide, so as to achieve stable sliding.

[0021] Limiting plates 5 are provided on both sides of the reference plate 4. The limiting plates 5 are arranged along the conveying direction of the conveyor belt 3, and the ends of the limiting plates 5 near the input end of the iron core extend outward. The limiting plates 5 can effectively limit the conveying range of the iron core on the reference plate 4. The opening of the limiting plate 5 is larger on the side of the iron core input end and smaller on the side of the iron core output end. This ensures stable conveying of the iron core. The height of the limiting plate 5 must be less than the height of the iron core, that is, there is a gap between the limiting plate 5 and the marking rod 6.

[0022] The telescopic mechanism is structured as follows: a mounting plate 9 is provided on the frame 1, a first cylinder 10 is horizontally provided on the mounting plate 9, the telescopic end of the first cylinder 10 faces the conveying direction of the conveyor belt 3, a mounting frame 14 is fixedly provided on the telescopic end of the first cylinder 10, a vertically downward second cylinder 11 is provided on the mounting frame 14, a push plate 12 is fixedly provided on the telescopic end of the second cylinder 11, and the push plate 12 is located within the range between the limiting plates 5.

[0023] The first cylinder 10 is fixed to the mounting plate 9. The first cylinder 10 can drive the mounting bracket 14 and the second cylinder 11 to move forward, and finally push the iron core to the front of the reference plate 4. Since the push plate 12 needs to lower the iron core when pushing it, and needs to be raised to avoid affecting the conveying of the iron core behind, the second cylinder 11 is used to connect the push plate 12 to realize the extension and retraction of the push plate 12, which is stable and efficient.

[0024] The marking groove 8 on the marking rod 6 is located at the end of the horizontal diameter. A feed inlet is provided on the marking rod 6, and a sealing cover 16 is provided at the feed inlet.

[0025] An ink inlet is provided on the marking rod 6 for adding ink, and the inlet is sealed with a sealing cap 16. The marking groove 8 on the marking rod 6 is relatively small, so ink will not overflow automatically during normal operation. Marking can only be made on the iron core when the iron core contacts the marking rod 6. The amount of ink in the marking groove 8 can be determined by the size of the air pressure balance hole 19 and the viscosity of the ink, and can be adjusted according to the actual situation. If the ink viscosity is high, the air pressure balance hole 19 can be larger to ensure that the amount of ink in the marking groove 8 remains stable and usable. If the ink viscosity is low, the air pressure balance hole 19 needs to be smaller to ensure that the amount of ink in the marking groove 8 is stable and will not overflow.
