[0013] 2. The device of this utility model is equipped with a clamping structure. By driving the cylinder on the electric sliding plate, one of the positioning seats moves, causing the positioning seat to drive the rack plate to mesh with the main gear and rotate. In turn, the main gear drives the positioning seat on the other rack plate to move relative to each other, causing the two clamping plates to move relative to each other to stably clamp the furnace parts. This keeps the parts stable during processing and avoids the impact of vibration or displacement on the spraying effect, thereby improving the stability of the spraying of furnace parts.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5As shown in the figure, this embodiment provides a furnace coating spraying equipment, including a spraying machine base 1. Two guide rails 3 are fixedly and symmetrically installed on the upper end of the spraying machine base 1, and a PLC controller 2 is fixedly installed on one side of the guide rails 3. A spraying structure 4 is fixedly installed on one side of the upper end of the spraying machine base 1. The spraying structure 4 includes a positioning frame 40 fixedly installed on the upper end of the spraying machine base 1. A lifting motor 43 is fixedly installed inside the positioning frame 40. A threaded screw 44 is fixedly connected to the output end of the lifting motor 43. A guide support plate 48 is threadedly connected to the outer wall of the threaded screw 44. An electric push rod 491 is provided above the guide support plate 48. A ring frame 492 is fixedly connected to one end of the electric push rod 491. A ring guide tube 462 is fixedly installed on the inner wall of the ring frame 492, and multiple discharge nozzles 463 are fixedly installed on the inner wall of the ring guide tube 462. A clamping structure 7 is provided on the upper end of the guide rails 3, and a furnace part 6 is provided inside the clamping structure 7.

[0024] like Figures 3 to 4 As shown, a storage tank 41 is fixedly installed on the upper end of the positioning frame 40, and a pump body 45 is fixedly installed on the upper end of the storage tank 41. One end of the pump body 45 and the storage tank 41 are fixedly connected to the same guide tube 46. One end of the guide tube 46 passes through the interior of the positioning frame 40 and the extended end is connected to a telescopic hose 461. The telescopic hose 461 is fixedly connected to an annular guide tube 462. A stirring motor 42 is fixedly installed on the upper end of the storage tank 41, and a stirring frame is fixedly installed on one end of the stirring motor 42. A distance sensor 5 is fixedly installed on the outer wall of the positioning frame 40. Two guide sliders 47 are symmetrically fixedly installed on the outer wall of the guide support plate 48 and are slidably connected to the outer wall of the positioning frame 40. A groove is opened inside the guide support plate 48. The bottom of the annular frame 492 is slidably connected to the groove. The annular frame 492 is adapted to the size of the furnace part 6. An electric push rod 491 is fixedly installed inside the two positioning blocks 49 and the positioning blocks 49 are fixedly connected to the upper end of the guide support plate 48.

[0025] The threaded screw 44 drives the annular frame 492 on the guide support plate 48 to move, causing the guide support plate 48 to slide and be limited on the positioning frame 40 by the guide slider 47. At the same time, the electric push rod 491 drives the annular frame 492 on the annular frame 492 to move and cooperate along the slide groove, so as to align the annular guide tube 462 on the annular frame 492 with the furnace part 6, and facilitate the all-round movement and spraying of the part. At the same time, the stirring motor 42 drives multiple stirring frames to rotate and uniformly stir the coating in the storage tank 41 to prevent solidification.

[0026] like Figure 5As shown, the clamping structure 7 includes an electric slide plate 71 slidably connected to the guide slide rail 3. A cylinder 72 is fixedly installed on one side of the upper end of the electric slide plate 71. One end of the cylinder 72 passes through the interior of the electric slide plate 71 and the extended end is fixedly connected to a positioning seat 73. There are two positioning seats 73 in total, and a rack plate 74 is fixedly installed inside each of the two positioning seats 73. A main gear 75 is meshed with the outer wall of each of the two rack plates 74. The main gear 75 is rotatably installed inside the electric slide plate 71. Two clamping plates 76 are fixedly installed on the upper end of each of the two positioning seats 73, and an anti-slip pad 77 is attached to the outer wall of each clamping plate 76. A limit slider 78 is fixedly installed at the bottom of each of the two positioning seats 73, and the limit slider 78 is slidably connected inside the limit slide rail 79. The two limit slide rails 79 are fixedly installed inside the electric slide plate 71. A placement platform 8 is fixedly installed on the upper end of the electric slide plate 71, and the placement platform 8 is adapted to the position of the furnace part 6.

[0027] By fixing anti-slip pads 77 on the outer walls of both clamping plates 76, it is easier to clamp the furnace parts 6 relatively stably. At the same time, when the two positioning seats 73 move, they use the limiting sliders 78 to slide on the limiting slide rails 79 to facilitate the stable movement of the two clamping plates 76 relative to each other to clamp and position the furnace parts 6.

[0028] The working principle and process of this utility model are as follows: First, the operator places the furnace part 6 to be sprayed on the placement platform 8, then connects the external power supply, and drives the cylinder 72 on the electric slide plate 71 to move one of the positioning seats 73. This causes the positioning seat 73 to drive the rack plate 74 to mesh with the main gear 75 and rotate. As a result, the main gear 75 drives the positioning seat 73 on the other rack plate 74 to move relative to each other, which causes the two clamping plates 76 to move relative to each other to stably clamp the furnace part 6. At the same time, when the two positioning seats 73 move, they slide on the limit slide rail 79 using the limit slider 78 to achieve precise positioning of the furnace part 6. After the furnace part 6 is fixed, the electric slide plate 71 is moved to the front of the positioning frame 40 by the cooperation of the PLC controller 2 and the distance sensor 5.

[0029] At this time, the lifting motor 43 drives the guide support plate 48 on the threaded screw 44 to move downward, and drives the electric push rod 491 on the two positioning blocks 49 to move the ring frame 492, so that the ring frame 492 on the guide support plate 48 fits with the top of the furnace part 6. Then, the pump body 45 drives the paint in the storage tank 41 to be transported to the telescopic hose 461 along the guide pipe 46, so that the paint is sprayed out from multiple discharge nozzles 463 along the ring guide pipe 462 to effectively spray the outside of the furnace part 6. At the same time, after spraying the outer wall of the furnace part 6, the lifting motor 43 drives the guide support plate 48 on the threaded screw 44 to move downward to spray the outer wall of the furnace part 6 in all directions. After the spraying is completed, the ring frame 492 is moved up, and then the furnace part 6 is moved to the next process. The spraying is carried out by moving along the size of the furnace, which reduces material waste and lowers the production cost of the enterprise.
