Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion materials technology, specifically a coating machine for spraying 3PE anti-corrosion materials. Background Technology

[0002] 3PE anti-corrosion material is a commonly used external anti-corrosion material for pipelines. Its full name is three-layer polyethylene anti-corrosion coating. With its excellent anti-corrosion performance, good mechanical properties, strong weather resistance and convenient construction characteristics, 3PE anti-corrosion material plays an important role in many pipeline anti-corrosion fields. It is one of the more ideal external anti-corrosion solutions for pipelines. Spraying equipment is required when applying 3PE anti-corrosion coating to the surface of steel pipes.

[0003] Existing spraying equipment has a relatively fixed spraying range, making it difficult to comprehensively and evenly cover the surfaces of workpieces with varying shapes and sizes. This leads to situations where the coating is too thick or too thin in certain areas when spraying 3PE anti-corrosion materials on workpieces. This not only affects the effective utilization of the anti-corrosion material but, more importantly, fails to guarantee the consistency and reliability of the overall anti-corrosion effect on the workpiece. Areas with insufficient protection may show signs of corrosion earlier, shortening the service life of the workpiece and even causing safety hazards; while areas with excessive thickness may waste anti-corrosion materials and increase costs. Therefore, a coating machine for spraying 3PE anti-corrosion materials is proposed. Utility Model Content

[0026] 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.

[0027] Example 1

[0028] like Figures 1-5 As shown, this embodiment proposes a housing 1 and a support leg 4 fixedly disposed on the bottom surface of the housing 1. The housing 1 is provided with a spraying mechanism 2 and a placement mechanism 5.

[0029] The placement mechanism 5 is located below the spraying mechanism 2;

[0030] The spraying mechanism 2 includes a spraying part and a rotating part;

[0031] The spraying section includes two sprayers 21 and a storage box 25, and the rotating section includes a gear 27 and a gear ring 28;

[0032] A ring rail 210 is fixedly installed on the top inner side of the outer casing 1. Two sliding sleeves 29 are slidably fitted on the surface of the ring rail 210. Two connecting brackets 22 are fixedly installed on the bottom surface of the two sliding sleeves 29 respectively. The bottom surface of the two connecting brackets 22 is fixedly connected to the top surface of the two sprayers 21 respectively. The surface of the two sliding sleeves 29 is fixedly connected to the inner side of the gear ring 28. A motor 26 is fixedly installed on the top surface of the outer casing 1. The bottom surface of the output end of the motor 26 extends through the top surface of the outer casing 1 into the interior of the outer casing 1. The surface of the output end of the motor 26 is fixedly connected to the inner side of the gear 27. The tooth surface of the gear 27 meshes with the tooth surface of the gear ring 28. A connecting pipe 23 is fixedly installed through the top surface of the outer casing 1 and extends outward. Inside the shell 1, a three-way pipe 213 is slidably fitted on the surface of the connecting pipe 23. Two connecting pipes 23 are respectively installed through the left and right ends of the three-way pipe 213. The two connecting pipes 23 are respectively fixedly connected to the liquid inlet ends of the two sprayers 21. The top surface of the shell 1 is fixedly connected to the bottom surface of the storage box 25. The back of the connecting pipe 23 is fixedly installed through the front of the storage box 25 and extends into the storage box 25. A liquid inlet pipe 24 is fixedly installed through the top surface of the storage box 25 and extends into the storage box 25. An annular groove is opened on the inner side of the three-way pipe 213. A fixing ring 212 is fixedly fitted on the surface of the connecting pipe 23. The surface of the fixing ring 212 is slidably connected to the inner wall of the annular groove.

[0033] In this embodiment, the motor 26 in the spraying mechanism 2 drives the gear 27 to rotate. Through the meshing of the gear 27 and the gear ring 28, the sliding sleeve 29, which slides along the ring rail 210, causes the spraying machine 21 to move circumferentially, expanding the spraying area, ensuring uniform coating on the workpiece surface, and improving the anti-corrosion effect. Simultaneously, the material conveying structure composed of the connecting pipe 23, the tee pipe 213, and the fixing ring 212, while ensuring a tight connection, allows the 3PE anti-corrosion material in the storage tank 25 to be stably conveyed to its inlet end as the spraying machine 21 moves, ensuring smooth coating operations.

[0034] Example 2

[0035] like Figures 1-5As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the placement mechanism 5 includes two fixing blocks 51, the bottom surfaces of which are fixedly connected to the inner bottom surface of the outer casing 1. Two lifting sleeves 58 are slidably sleeved on the surfaces of the two fixing blocks 51, and a placement plate 55 is fixedly installed on the top surface of each of the two lifting sleeves 58. Two clamping plates 56 are slidably installed on the top surface of the placement plate 55, and a through groove is opened through the top surface of the placement plate 55. Two control blocks 53 are slidably installed on the inner wall of the through groove, and the top surfaces of the two control blocks 53 are respectively connected to the two clamping plates 56. The bottom surface of the holding plate 56 is fixedly connected, and the right side of the placement plate 55 is fixedly provided with a fixing frame 59. The right end of the inner side of the fixing frame 59 is rotatably provided with a double-axis threaded rod 54 through a bearing seat. The left end of the double-axis threaded rod 54 passes through the right side of the two control blocks 53 and extends to the left side of the left control block 53. The top surface of the placement plate 55 is provided with a wedge-shaped groove. Two wedge blocks 57 are slidably provided on the inner wall of the wedge groove. The top surfaces of the two wedge blocks 57 are fixedly connected to the bottom surfaces of the two clamping plates 56 respectively. The front of the outer shell 1 is provided with a door, and the inner wall of the door is hinged to a door panel 3.

[0036] In this embodiment, when fixing a workpiece, the placement mechanism 5 places the workpiece on the placement plate 55. Rotating the dual-axis threaded rod 54 moves the clamping plate 56 towards the center, enabling convenient fixing of workpieces of different sizes. When adjusting the workpiece height, the electric telescopic rod 52, connected to the placement plate 55, allows the placement plate 55 to be moved up and down as needed, adjusting workpieces of different heights to the optimal coating position, thus improving the equipment's versatility and convenience.

[0037] In use, open the door panel 3, place the workpiece that needs to be coated with 3PE anti-corrosion material on the placement plate 55, and manually control the dual-axis threaded rod 54 to rotate. When the dual-axis threaded rod 54 rotates, the two clamping plates 56 can be moved towards the middle of the placement plate 55 through the two control blocks 53. The two clamping plates 56 can fix the workpiece on the placement plate 55 when they move towards the middle of the placement plate 55. After placement, adjust the height of the placement plate 55 according to the height of the workpiece. The placement plate 55 can be moved up and down by turning on the electric telescopic rod 52. After the workpiece height is adjusted, turn off the electric telescopic rod 52.

[0038] After placement, 3PE anti-corrosion material is first supplied to the storage tank 25 through the liquid inlet pipe 24. Then, the two sprayers 21 are turned on. After the two sprayers 21 are turned on, the 3PE anti-corrosion material inside the storage tank 25 can be extracted through the two connecting pipes 23, the three-way pipe 213 and the liquid delivery pipe 211. The workpiece can be coated with 3PE anti-corrosion material through the liquid outlet of the two sprayers 21. During the coating process, the motor 26 is turned on. When the output end of the motor 26 rotates, the gear 27 rotates. When the gear 27 rotates, the two sliding sleeves 29 can move in a circle through the gear ring 28. During the circumferential movement of the two sliding sleeves 29, the two sprayers 21 can be moved, thereby expanding the spraying area of ​​the two sprayers 21. Furthermore, the two sprayers 21 can coat the workpiece more evenly when moving in a circle.

[0039] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
