Description

Technical Field

[0001] This utility model relates to the field of transformer processing technology, and in particular to a transformer core coating device with a shielding function. Background Technology

[0002] In transformer manufacturing, the iron core, as one of the core components, typically requires an insulating adhesive coating to prevent inter-laminar short circuits, improve electrical performance, and enhance moisture and corrosion resistance. Traditional coating methods often employ manual brushing or overall spraying, but the coating precision is difficult to control, easily resulting in adhesive being applied to non-target areas, such as mounting holes, joints, or other precision structures within the iron core. This fails to achieve selective protection of specific areas, necessitating additional cleaning work after coating, affecting subsequent assembly and product quality, and even generating scrap due to misapplied adhesive, thus increasing production costs. Therefore, we propose a transformer iron core adhesive coating device with a shielding function. Utility Model Content

[0003] The main purpose of this utility model is to provide a transformer core coating device with shielding function, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A transformer core adhesive coating device with shielding function includes a side support plate. A motor is fixedly installed on one side of the side support plate. An adhesive coating string is fixedly connected to the output end of the motor and is movably connected to the side support plate. A limit ring is fixedly connected to the adhesive coating string. A nut is threadedly connected to the side of the adhesive coating string away from the limit ring. A shielding mechanism is fixedly installed on one side of the side support plate and is movably connected to the adhesive coating string through a bearing. The shielding mechanism includes a support frame, which is fixedly installed with a side support plate and movably connected to an adhesive-coated string rod via a bearing. Multiple shielding components are slidably connected on the support frame.

[0005] Preferably, the support frame includes a triangular support plate, the lower part of which is fixedly connected to an installation sleeve, the installation sleeve being fixedly inserted into the side support plate and movably connected to the glued string rod via a bearing, the upper end of which is fixedly connected to a support frame, and the shielding member being slidably connected within the support frame via a sliding groove.

[0006] By adopting the above technical solution: the triangular support plate, as a load-bearing structure, has good mechanical properties and can effectively enhance the rigidity and stability of the entire shielding mechanism. The mounting sleeve passes through the side support plate and is fixedly connected to it. At the same time, through the cooperation of bearings and glue-coating rods, it is ensured that the shielding mechanism maintains stable operation without affecting the rotation of the glue-coating rods. The support frame connected above provides a guide and load-bearing platform for the shielding components, allowing the shielding components to flexibly adjust their position along the slide, thereby improving the adaptability and ease of operation of the device.

[0007] Preferably, the support frame has a U-shaped structure, and two sliding grooves are symmetrically provided at the front and rear of the support frame.

[0008] By adopting the above technical solution, the rationality and functionality of the spatial layout of the shielding components are improved through the reasonable design of the support frame structure. The U-shaped support frame is not only simple in structure and high in strength, but also provides ample space for the installation and movement of the shielding components. The sliding grooves symmetrically arranged on its front and rear sides can guide the shielding components to slide freely in the plane direction, meet the shielding requirements of iron cores of different sizes and shapes, and enhance the versatility and flexibility of the equipment.

[0009] Preferably, the shielding component includes a shielding plate, and both ends of the shielding plate are fixedly connected to sliding sleeves, and the two sliding sleeves are symmetrically arranged. The two sliding sleeves are slidably connected to the front and rear sides of the support frame through sliding grooves, so that the shielding plate is slidably connected in the support frame.

[0010] By adopting the above technical solution, the shielding plate, as a key component that directly provides shielding, has a stable sliding connection structure formed at both ends through sliding sleeves that engage with sliding grooves on the support frame. This symmetrically arranged sliding sleeve structure not only improves the stability of the shielding plate during movement but also prevents it from tilting or jamming, thus ensuring the continuity and consistency of the shielding effect. Furthermore, the sliding connection method facilitates the quick disassembly and replacement of the shielding components, making daily maintenance and cleaning convenient.

[0011] Preferably, one end of one of the sliding sleeves is fixedly connected to a fixing plate, and a positioning screw is inserted through the middle of the fixing plate, and the positioning screw is threadedly connected to the fixing plate.

[0012] By adopting the above technical solution: by setting a fixing plate on one of the sliding sleeves and installing a rotatable positioning screw on it, the operator can tighten the positioning screw after the shielding plate is adjusted into place to achieve temporary fixation of the shielding component. The threaded connection method facilitates the adjustment of the force, which can ensure the locking effect without damaging the structure due to excessive tightening, thereby improving the ease of operation and practicality of the shielding component.

[0013] Preferably, a positioning groove is provided on one side of the support frame, and the positioning screw is interference-fitted with the positioning groove.

[0014] By adopting the above technical solution, multiple positioning slots on the support frame can form an interference fit with the positioning screws. After the shielding plate is adjusted to the appropriate position, the shielding plate can be securely locked by inserting the positioning screws into the corresponding positioning slots. This structure is not only easy to operate but also accurate in positioning, effectively preventing the shielding plate from shifting due to vibration or airflow disturbance during the glue application process, thereby ensuring the stability of the shielded area and the quality of the glue application.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The shielding mechanism is designed to allow for the installation of one or more shielding components on the support frame, effectively blocking areas of the iron core that do not require adhesive application. This shielding mechanism features a stable overall structure and a rational layout, allowing for flexible adjustment of the shielding range based on the shape characteristics of different iron cores. This prevents adhesive from being accidentally applied to mounting holes, joints, or other critical areas, effectively reducing subsequent cleaning workload and improving product consistency and yield. Furthermore, the shielding mechanism is movably connected to the adhesive application bar via bearings, achieving stable shielding without affecting the normal rotation of the adhesive application bar, thus enhancing the overall coordination and operational reliability of the device.

[0016] 2. Each shielding component includes a shielding plate with sliding sleeves at both ends. These sleeves engage with grooves on the support frame, allowing free sliding along the front and rear sides of the support frame. This enables flexible horizontal adjustment of the shielding position to accommodate cores of different sizes and structures. Once the shielding plate is adjusted to the desired position, the operator can rotate the positioning screw fixed at one end to insert it into a positioning groove on one side of the support frame. An interference fit securely locks the shielding plate in place, preventing displacement during adhesive application due to vibration or airflow disturbances, thus ensuring shielding accuracy and adhesive quality. This structure not only improves the adaptability and ease of operation of the equipment but also significantly enhances the stability and reusability of the shielding components.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-4 This utility model provides a technical solution: A transformer core adhesive coating device with shielding function includes a side support plate 1. A motor 2 is fixedly installed on one side of the side support plate 1. An adhesive coating string 3 is fixedly connected to the output end of the motor 2 and is movably connected to the side support plate 1. A limit ring 4 is fixedly connected to the adhesive coating string 3. A nut 5 is threadedly connected to the side of the adhesive coating string 3 away from the limit ring 4. A shielding mechanism 6 is fixedly installed on one side of the side support plate 1 and is movably connected to the adhesive coating string 3 through a bearing.

[0023] In this embodiment, the shielding mechanism 6 includes a support frame 7, which is fixedly installed on the side support plate 1 and movably connected to the glue-coating rod 3 via bearings. Multiple shielding components 8 are slidably connected on the support frame 7. The support frame 7 includes a triangular support plate 71, with an installation sleeve 72 fixedly connected to the lower part of the triangular support plate 71. The installation sleeve 72 is fixedly inserted into the side support plate 1 and movably connected to the glue-coating rod 3 via bearings. A support frame 73 is fixedly connected to the upper end of the triangular support plate 71. The support frame 73 has a U-shaped structure, with two symmetrical sliding grooves 731 on both the front and rear parts of the support frame 73. The shielding components 8 are slidably connected to the support frame 73 via the sliding grooves 731.

[0024] The above solution involves installing one or more shielding elements 8 on the support frame 73 according to the actual glue application requirements, in order to effectively shield the areas in the iron core that do not require glue application.

[0025] In this embodiment, the shielding component 8 includes a shielding plate 81. Both ends of the shielding plate 81 are fixedly connected to sliding sleeves 82, and the two sliding sleeves 82 are symmetrically arranged. The two sliding sleeves 82 are slidably connected to the front and rear sides of the support frame 73 through sliding grooves 731, thereby slidably connecting the shielding plate 81 within the support frame 73. One end of one of the sliding sleeves 82 is fixedly connected to a fixing plate 83. A positioning screw 84 is inserted through the middle of the fixing plate 83, and the positioning screw 84 is threadedly connected to the fixing plate 83. A positioning groove 732 is provided on one side of the support frame 73, and the positioning screw 84 is interference-fitted with the positioning groove 732.

[0026] The above scheme involves each shielding component 8 including a shielding plate 81. The shielding plate 81 has sliding sleeves 82 at both ends, which can slide freely along the front and rear sides of the support frame 73 via the sliding groove 731, thereby achieving flexible adjustment of the shielding position. After the shielding plate 81 is adjusted to the required position, the operator rotates the positioning screw 84 fixed at one end to insert it into the positioning groove 732 pre-set on one side of the support frame 73. The interference fit is used to achieve a stable lock of the shielding plate 81, preventing it from shifting due to vibration or airflow disturbance during the subsequent glue application process, which would affect the shielding effect.

[0027] It should be noted that this utility model is a transformer core gluing device with a shielding function. During use, the transformer core to be glued is first placed on the gluing rod 3, with one end of the core abutting against the limiting ring 4 for axial positioning. Then, the nut 5 is tightened to firmly fix the core onto the gluing rod 3, ensuring no shifting or loosening during subsequent rotation. Next, according to actual gluing requirements, one or more shielding components 8 are installed on the support frame 73 to effectively shield areas of the core that do not require gluing. Each shielding component 8 includes a shielding plate 81, with sliding sleeves 82 at both ends. These sleeves can slide freely along the front and rear sides of the support frame 73 via a sliding groove 731, allowing flexible adjustment of the shielding position. Once the shielding plate 81 is adjusted to the desired position, the operator can fix it by rotating it. The positioning screw 84 at one end is inserted into the positioning groove 732 pre-set on one side of the support frame 73. The interference fit securely locks the shielding plate 81, preventing it from shifting due to vibration or airflow disturbance during subsequent glue application, thus affecting the shielding effect. After the iron core installation and shielding component 8 are completed, the motor 2 is started. The output end of the motor 2 is fixedly connected to the glue application string 3, driving the glue application string 3 and the iron core fixed on it to rotate synchronously. During this process, glue is applied to the outer surface of the iron core. As the iron core rotates, the glue is evenly applied to the outer circumference of the iron core, achieving a continuous and stable glue application effect. After the glue application is completed, the motor 2 is turned off. First, loosen the nut 5 to remove the iron core. Then, slide or disassemble the shielding component 8 as needed for cleaning or replacement, which facilitates maintenance and reuse, and improves the service life and working efficiency of the equipment.
