Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transformer spraying technology, and specifically relates to a spraying device. Background Technology
[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, the iron core (magnetic core), and the outer shell. Currently, in order to improve the performance of transformers, special spraying equipment is usually required to spray protective coating on their exterior.
[0003] A high-efficiency transformer manufacturing spraying device, disclosed in CN202420030830.8, utilizes the synergistic action of spraying, rotating, moving, and fixed components to simultaneously spray three sides of the transformer casing. The device rotates the transformer casing during spraying, enabling complete casing spraying without multiple disassemblies and reassemblies. While it boasts high spraying efficiency and excellent results, significantly improving work efficiency, this device still has shortcomings in practical applications. Particularly in spraying the bottom of the transformer, structural limitations prevent effective coverage of the bottom area, resulting in incomplete spraying. After the initial spraying, the transformer must be disassembled and the bottom sprayed separately, increasing operational complexity and significantly reducing overall work efficiency, thus affecting the smoothness of the production process. Utility Model Content
[0004] In view of this, the present invention provides a spraying device that can achieve uniform coverage of the entire surface of a transformer in a single operation through the synergistic effect of a three-dimensional spraying layout and a synchronous lifting mechanism, effectively avoiding the problems of missed spraying or repeated spraying, significantly improving work efficiency, while reducing paint loss and ensuring the consistency of coating quality.
[0005] To solve the above-mentioned technical problems, this utility model provides a spraying device, including a spraying chamber and a hoisting line set at the upper end of its inner cavity. The spraying chamber is also equipped with a spraying mechanism, which includes guide rods symmetrically arranged on both sides of the inner cavity of the spraying chamber. A mounting frame is slidably connected between two adjacent guide rods on the same side. Multiple spray heads are provided on the inner side of the mounting frame, and multiple spray heads are provided on both sides of the inner side of the mounting frame. A spraying pipeline is provided at one end of the mounting frame, and two spraying pipelines are staggered. The spraying chamber is also equipped with a drive component for driving the mounting frame to move up and down reciprocally. That is, through the synergistic effect of the three-dimensional spraying layout and the synchronous lifting mechanism, the entire surface of the transformer can be uniformly covered in a single operation, effectively avoiding the problems of missed spraying or repeated spraying, significantly improving the work efficiency, while reducing paint loss and ensuring the consistency of coating quality.
[0006] The drive assembly includes lead screws that are rotatably connected to both sides of the inner cavity. The lead screws are threadedly connected to the adjacent mounting brackets on the same side, thus driving the mounting brackets and their auxiliary mechanisms.
[0007] The drive assembly also includes fixed plates symmetrically arranged at the top of the spray booth. A rotating rod is rotatably connected between the two fixed plates. Both ends of the rotating rod are provided with bevel gear one, and the upper extension end of the lead screw is provided with bevel gear two. The bevel gear two meshes with the adjacent bevel gear one on the same side, thus playing the role of rapid transmission.
[0008] The drive assembly also includes a motor located on one side of the upper end of the spray booth. The output shaft of the motor is fixedly connected to one end of the rotating rod, thus providing the drive source.
[0009] A protective shell is provided between the two fixed plates. The rotating rod, bevel gear one, and bevel gear two are all located inside the protective shell, which forms an isolation and protection for their internal structure.
[0010] The inner cavity of the spray booth is equipped with protective covers on both sides, and each protective cover has a through-hole that is compatible with the mounting bracket, which can isolate and protect it.
[0011] The multiple spray heads at the top are all tilted downwards, while the multiple spray heads at the bottom are all tilted upwards, enabling a three-dimensional spraying operation on the transformer.
[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0013] 1. The transformer to be coated is suspended in the center of the spray booth via a hoisting line. The drive assembly drives the mounting frame and its auxiliary mechanisms to move up and down along the guide rod. During the movement of the mounting frame, the downward-sloping spray head 1, the upward-sloping spray head 1, and the horizontally placed spray head 2 work together to form multi-angle coverage. Simultaneously, with the lifting and lowering of the mounting frame, the top, sides, and bottom of the transformer can be sprayed at the same time. The staggered spray pipelines ensure that both ends of the transformer are sprayed. Through the synergistic effect of the three-dimensional spray layout and the synchronous lifting mechanism, the entire surface of the transformer can be uniformly covered in a single operation, effectively avoiding missed spraying or repeated spraying, significantly improving work efficiency, reducing paint waste, and ensuring consistent coating quality.
[0014] 2. Start the motor. Its output shaft drives the rotating rod and the first bevel gear at both ends to rotate synchronously. When the first bevel gear rotates, it drives the lead screws on both sides to rotate synchronously through the second bevel gear that meshes with it. This causes the mounting frame and its auxiliary mechanism to move up and down along the guide rod, thus achieving synchronous movement.
[0015] 3. The protective shell and protective cover provide isolation and protection for the internal structure. Attached Figure Description

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0023] This embodiment provides a spraying device, such as Figure 1-5 As shown: The spray booth 100 includes a hoisting line 200 located at the upper end of its inner cavity. The spray booth 100 is also equipped with a spraying mechanism, which includes guide rods 300 symmetrically arranged on both sides of the inner cavity of the spray booth 100. A mounting frame 301 is slidably connected between two adjacent guide rods 300 on the same side. Multiple spray heads 302 are provided on the inner side of the mounting frame 301. Multiple spray heads 303 are provided on both sides of the inner side of the mounting frame 301. A spraying pipeline 304 is provided at one end of the mounting frame 301. Two spraying pipelines 304 are staggered. The spraying pipeline 304, the second spray head 303, and the first spray head 302 are all connected to the corresponding external material supply pipe. The spray booth 100 is also equipped with a drive assembly for driving the mounting frame 301 to move up and down reciprocally.
[0024] The transformer to be coated is suspended in the center of the spray booth 100 via the hoisting line 200. Then, the drive assembly drives the mounting frame 301 and its auxiliary mechanisms to move up and down along the guide rod 300. During the movement of the mounting frame 301, the downward-sloping spray head 302, the upward-sloping spray head 302, and the horizontally placed spray head 303 work together to form multi-angle coverage. At the same time, with the lifting and lowering of the mounting frame 301, the top, sides and bottom of the transformer can be sprayed simultaneously. The staggered spray pipeline 304 ensures that both ends of the transformer are sprayed. Through the synergistic effect of the three-dimensional spray layout and the synchronous lifting mechanism, the entire surface of the transformer can be uniformly covered in a single operation, effectively avoiding the problems of missed spraying or repeated spraying, significantly improving work efficiency, reducing paint loss and ensuring the consistency of coating quality.
[0025] like Figure 1-5 As shown, the drive assembly includes lead screws 400 rotatably connected to both sides of the inner cavity. The lead screws 400 are threadedly connected to the adjacent mounting brackets 301 on the same side. The drive assembly also includes fixed plates 401 symmetrically arranged at the upper end of the spray booth 100. A rotating rod 402 is rotatably connected between the two fixed plates 401. Both ends of the rotating rod 402 are provided with bevel gears 403. The upper extension end of the lead screws 400 is provided with bevel gears 404. The bevel gears 404 are meshed with the adjacent bevel gears 403 on the same side. The drive assembly also includes a motor 405 arranged on one side of the upper end of the spray booth 100. The output shaft of the motor 405 is fixedly connected to one end of the rotating rod 402.
[0026] When the motor 405 is started, its output shaft drives the rotating rod 402 and the bevel gears 403 at both ends to rotate synchronously. When the bevel gear 403 rotates, it drives the lead screws 400 on both sides to rotate synchronously through the bevel gear 404 that meshes with it. This causes the mounting bracket 301 and its auxiliary mechanisms to move up and down along the guide rod 300, thus achieving a rapid driving effect.
[0027] like Figure 1-5 As shown, a protective shell 500 is provided between the two fixed plates 401. The rotating rod 402, bevel gear one 403 and bevel gear two 404 are all located inside the protective shell 500, and the protective shell 500 forms an isolation and protection for its internal structure.
[0028] like Figure 1-4 As shown, protective covers 600 are provided on both sides of the inner cavity of the spray booth 100. Each protective cover 600 has a through-hole that is compatible with the mounting bracket 301. The lead screw 400 is located inside the protective cover 600, which can isolate and protect it to ensure its normal operation.
[0029] like Figure 1-4As shown, the multiple spray heads 2 303 at the top are all tilted downwards, while the multiple spray heads 2 303 at the bottom are all tilted upwards, enabling a three-dimensional spraying operation on the transformer.
[0030] The working principle of the spraying device provided by this utility model is as follows: The transformer to be sprayed is suspended in the center of the spray booth 100 by the hoisting line 200. Then, the motor 405 is started, and its output shaft drives the rotating rod 402 and the bevel gears 403 at both ends to rotate synchronously. When the bevel gear 403 rotates, it drives the lead screws 400 on both sides to rotate synchronously through the bevel gear 404 meshing with it. This causes the mounting frame 301 and its auxiliary mechanism to move up and down along the guide rod 300. During the movement of the mounting frame 301, the downward tilting spray head 302 and the upward tilting spray head 302 and the lead screw 403 at both ends rotate synchronously. The horizontally placed spray head 303 works together to form multi-angle coverage. Simultaneously, with the lifting and lowering of the mounting bracket 301, the top, sides, and bottom of the transformer can be sprayed at the same time. The staggered spray pipeline 304 ensures that the two ends of the transformer are sprayed. Through the synergistic effect of the three-dimensional spraying layout and the synchronous lifting mechanism, the entire surface of the transformer can be uniformly covered in a single operation, effectively avoiding the problems of missed spraying or repeated spraying, significantly improving work efficiency, reducing paint loss, and ensuring the consistency of coating quality. The protective shell 500 and the protective cover 600 respectively form isolation and protection for its internal structure.
[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
