Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically a pipeline spraying device for uniform coating. Background Technology

[0002] Spray coating is a surface treatment method widely used in various fields, including industrial production, construction, artistic creation, and the manufacture of everyday items. The core of this technology lies in using a spray gun to atomize and evenly spray liquid coating materials (including but not limited to paints, latex paints, and powder coatings) onto the surface of a target object, thus forming a protective or decorative coating. The application of spray coating technology goes beyond simply enhancing the appearance of items; it can also impart rich colors and unique textures. Furthermore, the resulting coating possesses multiple practical functions such as corrosion resistance, rust prevention, weather resistance, and insulation, greatly enhancing the performance and lifespan of the items.

[0003] To improve the corrosion resistance of metal pipes, a special protective layer is usually applied to their surface. During the spraying process, workers hold a spray gun and move it back and forth along the pipe surface to cover the entire surface with paint. However, this handheld spraying may result in repeated spraying of the same area, leading to uneven paint distribution. Uneven coating reduces the paint's protective properties, such as rust prevention, corrosion resistance, and weather resistance, thus affecting the lifespan of the object. Summary of the Invention

[0004] The purpose of this invention is to provide a pipeline spraying device for uniform coating, so as to solve the problem of uneven coating in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipeline spraying device for uniform coating, comprising an equipment base, an equipment shell fixedly mounted on the equipment base, a protective cover fixedly mounted at one end of the equipment shell, a positioning mechanism installed inside the equipment shell, the positioning mechanism comprising a positioning frame fixedly mounted inside the equipment shell and a hydraulic cylinder fixedly mounted at one end of the equipment shell, a first conical clamping block rotatably mounted at one end of the positioning frame, a sliding crossbeam slidably mounted at the other end of the positioning frame, a second conical clamping block rotatably mounted on the sliding crossbeam, and the output end of the hydraulic cylinder fixedly connected to the sliding crossbeam, and a spraying mechanism provided on one side of the positioning frame.

[0006] Preferably, both the first and second conical clamping blocks are provided with movable shafts, and a movable sliding groove is provided on one side of the positioning frame.

[0007] Preferably, one end of the equipment housing has a through hole, and the output end of the hydraulic cylinder extends into the equipment housing through the through hole.

[0008] Preferably, the first conical clamping block is rotatably mounted on one end of the positioning frame via a movable shaft, the second conical clamping block is rotatably mounted on the sliding crossbeam via a movable shaft, and the second conical clamping block is slidably mounted on the other end of the positioning frame via the sliding crossbeam.

[0009] Preferably, the spraying mechanism includes a drive screw rotatably mounted in a movable slide and a drive motor fixedly mounted on a protective cover. The output end of the drive motor is fixedly mounted with a drive shaft. The drive screw is provided with a first reducer, which drives a second reducer on the movable shaft. A screw slider is connected to the drive screw, and a spray head is fixedly mounted on the screw slider. The drive shaft, the drive screw, and the movable shaft are all provided with helical gears, and the helical gears mesh together in pairs.

[0010] Preferably, the protective cover is provided with a bearing, and the drive shaft is movably mounted inside the protective cover via the bearing.

[0011] Preferably, the lead screw slider is slidably mounted on the positioning frame via a movable slide groove, and the nozzle is movably mounted within the positioning frame via the lead screw slider.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, after the drive motor is started, it will drive the drive shaft to rotate. After being reduced in speed by the first and second reducers, the drive shaft will then drive the drive screw and the movable shaft to rotate. After the movable shaft rotates, it will cause the first conical clamp to rotate, which in turn will drive the pipe to be coated to rotate. At the same time, the rotation of the drive screw will drive the screw slider to move laterally. The lateral movement of the slider will guide the nozzle to move along the rotating pipe to be coated, so as to achieve uniform spraying of the coating material on the surface of the pipe.

[0014] 2. In the application process of this application, the pipe to be coated is first placed between the first conical clamp and the second conical clamp. Then, the sliding beam is moved forward by the hydraulic cylinder. The forward movement of the sliding beam will cause the second conical clamp to move forward synchronously, thereby clamping the pipes to be coated with different diameters, so as to facilitate the coating operation on pipes of different sizes.

[0020] 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.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a pipe spraying device for uniform coating, including a device base 1, a device housing 2 fixedly installed on the device base 1, a protective cover 3 fixedly installed at one end of the device housing 2, a positioning mechanism 4 installed inside the device housing 2, and a spraying mechanism 5 provided on one side of the positioning frame 401. Through the cooperation of the positioning mechanism 4 and the spraying mechanism 5, the coating can be uniformly sprayed onto the surface of pipes of different diameters.

[0022] like Figure 2 and Figure 3 As shown, the positioning mechanism 4 includes a positioning frame 401 fixedly installed inside the equipment housing 2 and a hydraulic cylinder 406 fixedly installed at one end of the equipment housing 2. A first conical clamping block 402 is rotatably installed at one end of the positioning frame 401, and a sliding crossbeam 407 is slidably installed at the other end of the positioning frame 401. A second conical clamping block 405 is rotatably installed on the sliding crossbeam 407, and the output end of the hydraulic cylinder 406 is fixedly connected to the sliding crossbeam 407. Both the first conical clamping block 402 and the second conical clamping block 405 are provided with movable shafts 403. A movable sliding groove 404 is opened on one side of the positioning frame 401, and a through hole is opened at one end of the equipment housing 2. The output end of the hydraulic cylinder 406 extends into the equipment housing 2 through the through hole.

[0023] Specifically, when the pipe to be coated is placed between the first conical clamp 402 and the second conical clamp 405, the sliding beam 407 can be moved forward by the hydraulic cylinder 406. As the sliding beam 407 moves forward, it further pushes the second conical clamp 405 forward as well, thus firmly clamping pipes of different diameters between the first conical clamp 402 and the second conical clamp 405. This design makes spraying operations on pipes of various diameters more convenient and efficient.

[0024] like Figure 2 and Figure 4 As shown, the spraying mechanism 5 includes a drive screw 506 rotatably mounted in the movable slide 404 and a drive motor 501 fixedly mounted on the protective cover 3. The output end of the drive motor 501 is fixedly mounted with a drive shaft 503. The drive screw 506 is provided with a first reducer 504, which drives the movable shaft 403 to be provided with a second reducer 505. The drive screw 506 is connected to a screw slider 507, and the screw slider 507 is fixedly mounted with a spray head 508. The drive shaft 503, the drive screw 506 and the movable shaft 403 are all provided with helical gears 502, and the helical gears 502 mesh together in pairs. The protective cover 3 is provided with a bearing, and the drive shaft 503 is movably mounted in the protective cover 3 through the bearing.

[0025] Specifically, when the drive motor 501 is started, it begins to rotate, causing the drive shaft 503 to rotate accordingly. During rotation, the drive shaft 503, through the reduction action of the first reducer 504 and the second reducer 505, drives the drive screw 506 and the movable shaft 403 to rotate together. The rotation of the movable shaft 403 further causes the first conical clamp 402 to rotate. With the rotation of the first conical clamp 402, it causes the pipe to be coated to begin rotating. Simultaneously, the rotation of the drive screw 506 causes the screw slider 507 to move laterally. During this lateral movement, the screw slider 507 drives the nozzle 508 to move along the rotating pipe to be coated. In this way, the nozzle 508 can evenly spray the coating material onto the surface of the pipe, ensuring the uniformity and efficiency of the coating process.

[0026] Working principle: When using this equipment, the pipe to be coated is first placed between the first conical clamp 402 and the second conical clamp 405. Then, by operating the hydraulic cylinder 406, the sliding beam 407 is driven forward. As the sliding beam 407 moves forward, it further pushes the second conical clamp 405 forward, thus firmly clamping pipes of different diameters between the first conical clamp 402 and the second conical clamp 405. Then, the drive motor 501 can be started. Starting the drive motor 501 will drive the drive shaft 503 to rotate. After being reduced in speed by the first reducer 504 and the second reducer 505, the drive shaft 503 will drive the drive screw 506 and the movable shaft 403 to rotate. After the movable shaft 403 rotates, it will drive the first conical clamp 402 to rotate. After the first conical clamp 402 rotates, it will drive the pipe to be coated to rotate. After the drive screw 506 rotates, it will drive the screw slider 507 to move laterally. After the screw slider 507 moves laterally, it will drive the nozzle 508 to move along the rotating pipe to be coated, thereby spraying the spray material evenly on the surface of the pipe to be coated.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
