This spraying device fixes both ends of the pipe to the clamping mechanism before spraying. Since the pipes vary in length due to different dimensions, this spraying device can only spray individual pipes. After spraying, the pipe needs to be loaded for further spraying, making continuous pipe spraying impossible and reducing the overall processing efficiency of the thermal insulation pipe.

Detailed Implementation

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figure 1 and Figure 3This embodiment proposes a novel processing device for duplex polyurethane insulation pipes, including two outer frames 1. The inner walls of the two outer frames 1 are provided with centering components 2 for centering the pipe. A spraying frame 3 for spraying is also fixedly installed on the inner wall of the outer frames 1. A liquid storage ring 31 for conveying spraying liquid is fixedly installed on the outer side of the spraying frame 3. A spraying ring 32 for rotating spraying is rotatably connected to the inner wall of the liquid storage ring 31. The outer side of the spraying ring 32 is rotatably connected to the inner wall of the spraying frame 3. Multiple telescopic nozzles 33 for spraying are connected to the inner wall of the spraying ring 32. A rotating component 4 for driving the spraying ring 32 to rotate for spraying is provided on the inner wall of the spraying frame 3. Conveying components 5 for uninterrupted pipe transport are provided on both sides of the outer frames 1. An adjusting plate 34 is fixedly installed on the outer side of the telescopic nozzle 33. A component is fixedly installed on one side of the adjusting plate 34. A second electric telescopic rod 35 is provided, with its fixed end fixedly connected to the inner wall of the spraying ring 32. The insulation pipe is continuously and uninterruptedly conveyed by the conveying component 5, thereby conveying the insulation pipe to the centering component 2. The centering component 2 then assists in centering the insulation pipe. As the insulation pipe continues to move forward to the inner side of the spraying ring 32, the telescopic nozzle 33 can be adjusted by the second electric telescopic rod 35 to move to a suitable position with the insulation pipe. The polyurethane used inside the liquid storage ring 31 can be connected to the spraying ring 32 and conveyed to the inside of the spraying ring 32. The spraying ring 32 sprays polyurethane from the telescopic nozzle 33 onto the insulation pipe. At the same time, the rotating component 4 drives the spraying ring 32 to rotate on the inner wall of the spraying frame 3, which can improve the uniformity of the polyurethane spraying operation on the insulation pipe.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5This embodiment proposes a novel processing device for duplex polyurethane insulation pipes. The centering component 2 includes a centering frame 21 fixedly installed on the inner wall of the outer frame 1. Four first electric telescopic rods 22 are fixedly installed on the inner wall of the centering frame 21. Push plates 23 are fixedly installed at the telescopic ends of the four first electric telescopic rods 22. When the insulation pipe moves to the position of the centering frame 21, the first electric telescopic rods 22 on the inner wall of the centering frame 21 can drive the push plates 23 to push, so that the four push plates 23 can assist the insulation pipe in being in the position of the centering frame 21, maintaining the centering of the insulation pipe when it moves to the inner wall of the spraying ring 32. The rotating component 4 includes a drive gear ring 41 fixedly installed on the outer side of the spraying ring 32. The outer side of the drive gear ring 41 is rotatably connected to the inner wall of the spraying frame 3. The rotating assembly 4 also includes a drive motor 42 fixedly mounted on the outside of the spray frame 3. A drive gear 43 is fixedly mounted on the output end of the drive motor 42. The drive gear 43 meshes with the drive gear ring 41. The spray ring 32 is driven by the drive motor 42 to rotate the drive gear 43, thereby driving the drive gear ring 41 to rotate, increasing the uniformity of polyurethane spraying by the telescopic nozzle 33. The conveying assembly 5 includes four conveying seats 51. Adjusting screws 52 are threaded to both ends of the four conveying seats 51. Displacement rods 53 are fixedly mounted on both sides of the conveying seats 51. The outer sides of the adjusting screws 52 and the displacement rods 53 are rotatably connected to the inner sidewall of the outer frame 1. Component 5 also includes two pulleys 54 rotatably connected to the inner wall of the conveyor seat 51. A transmission belt 55 is fitted onto the outer side of each pulley 54. A conveyor motor 56 is fixedly installed on the inner wall of the conveyor seat 51, and the output end of the conveyor motor 56 is fixedly connected to one end of each pulley 54. The conveyor assembly 5 also includes a main motor 57 fixedly installed on the top of the outer frame 1. Both ends of the adjusting screw 52 are fixedly fitted with linkage wheels 58. A first belt 59 and a second belt 510 are respectively fitted onto the outer side of the linkage wheels 58. The distance between the two relative conveyor seats 51 can be adjusted according to the size of the insulation pipe. The main motor 57 drives the adjusting screw 52, ​​allowing the adjusting screw 52 to pass through the linkage wheels 58 and the first belt 59. The function is to adjust the distance between the two conveyor seats 51. At the same time, through the action of the linkage wheel 58 and the second belt 510, the conveyor seats 51 on both sides of the spray frame 3 can be driven to adjust the distance synchronously. While the distance between the two opposite conveyor seats 51 is adjusted, the displacement rod 53 slides on the outer frame 1, so that the two conveyor seats 51 can be adjusted to the same distance upward and downward relative to the center position of the spray frame 3, which improves the determination of the center height position of the insulation pipe. The insulation pipe on the conveyor seat 51 can be driven by the conveyor motor 56 to drive the pulley 54 to rotate, so that the pulley 54 can drive the transmission belt 55 to drive the insulation pipe forward. After the surface of the sprayed insulation pipe is dried, it moves to the other end of the outer frame 1 to the conveyor seat 51 position for output.

[0026] In this embodiment, during use, the insulation pipe can be continuously and uninterruptedly transported by the transmission belt 55 on the conveyor seat 51. The first electric telescopic rod 22 drives the push plate 23 to fit and limit the insulation pipe around its perimeter, so that the insulation pipe moves towards the inside of the spray frame 3 in a central position. This effectively moves the insulation pipe to the central position of the spray frame 3. At this time, the spray ring 32 sprays the polyurethane inside the liquid storage ring 31 from the telescopic nozzle 33. The spray ring 32 is driven to rotate inside the spray frame 3 by the drive gear 43. At this time, the telescopic nozzle 33 on the spray ring 32 performs efficient and uniform spraying treatment, thereby improving the working efficiency of the overall processing device in spraying the insulation pipe.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
