Description

Technical Field

[0001] The utility model relates to the technical field of pipeline coating, in particular to a pipeline rapid automatic coating system. Background Art

[0002] The pipeline coating process generally consists of pre-treatment, spraying, drying and other processes. Pre-treatment is to polish the outer wall of the pipeline, spraying is to spray paint on the pipeline, and drying is to dry the paint film after spraying. However, the product specifications of most existing large-scale pipeline coating production lines are relatively simple, and it is impossible to achieve mixed production of multiple processes, which leads to low production efficiency in the production process. It is difficult for a simple spraying production line for pipelines to produce high-quality coating products.

[0003] During the pipeline painting process, multi-angle spraying is required to achieve the effect of uniform paint film thickness. The pipeline that has been sprayed needs to be transported to the next drying stage. During the transportation process, the paint film on the pipeline is very easy to be bumped and scratched, that is, the paint film drying process cannot be carried out at the position where the spraying is completed on the pipeline, resulting in unqualified pipeline quality and low pipeline painting production efficiency.

Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0038] Embodiment 1

[0039] like Figure 1-Figure 8 As shown, a pipeline 4 rapid automatic coating system of this embodiment includes a spraying device 1 and a drying device 2;

[0040] Specifically, the spraying device 1 includes a first box body 11, multiple first rollers 12, a spraying mechanism 13 and a clamping device 14. The first box body 11 has openings at the bottom and both ends. The multiple first rollers 12 are installed on the bottom wall of the first box body 11 at intervals and can be rotated. The pipeline 4 is placed flat on the multiple first rollers 12. The axial direction of the pipeline 4 is perpendicular to the axial direction of the first rollers 12. The friction force of the pipeline 4 when moving on the multiple rollers is smaller, which is more conducive to the movement of the pipeline 4 on the multiple rollers; the clamping device 14 can be raised and lowered into the first box body 11 or is located below the first box body 11, and the clamping device 14 can clamp the pipeline 4 and drive the pipeline 4 to rotate around the axis of the pipeline 4 when it is inside the first box body 11. By setting the clamping device 14, the pipeline 4 can be clamped. Since the clamping device 14 can rotate, it can drive the pipeline 4 to rotate around the axis of the pipeline 4, so that the spraying mechanism 13 can spray the pipeline 4 at various angles, avoiding that a certain part of the pipeline 4 is not sprayed by the spraying mechanism 13, thereby reducing the quality of the pipeline 4; a long through hole along the length direction of the first box body 11 is opened on the top wall of the first box body 11 located directly above the pipeline 4, and the spraying mechanism 13 is movably installed on the long rail 111 through the first rail 111. In the through hole, the spraying mechanism 13 can move back and forth on the first track 111, so as to realize the spraying of the pipeline 4; a plurality of drying devices 2 are installed at equal intervals on the upper part of the side walls on both sides of the first box body 11, and the drying device 2 can be opened or closed to immediately dry the pipeline 4 after spraying. After the spraying mechanism 13 completes the spraying of the pipeline 4, the drying mechanism can be immediately opened to dry the pipeline 4 after spraying, thereby realizing the integration of spraying and drying, improving work efficiency, and at the same time improving the production quality of the pipeline 4.

[0041] Furthermore, the spraying mechanism 13 includes a spray gun 131 and a telescopic member 132; the spray gun 131 is installed on the first rail 111 through the telescopic member 132, and the telescopic member 132 can drive the spray gun 131 to rise and fall vertically, thereby realizing the spraying of pipelines 4 of different diameters and pipelines 4 at different heights between the pipelines 4 and the top of the first box body 11, thereby improving the efficiency of the spraying mechanism 13 and making the spraying mechanism 13 more adaptable.

[0042] Furthermore, the clamping device 14 includes a first clamping mechanism 141 and a second clamping mechanism 142; the first clamping mechanism 141 and the second clamping mechanism 142 are relatively arranged in a direction perpendicular to the first roller 12 and the axes of the first clamping mechanism 141 and the second clamping mechanism 142 are always consistent during the lifting process, which can not only clamp the pipeline 4, but also avoid the angle change of the pipeline 4, thereby avoiding uneven spraying of the pipeline 4 during the spraying process and avoiding the reduction of the quality of the pipeline 4; the first clamping mechanism 141 is fixedly installed at the bottom of the first box body 11, and the second clamping mechanism 142 is movably installed at the bottom of the first box body 11. The second clamping mechanism 142 can move in a direction close to or away from the first clamping mechanism 141, thereby clamping pipelines 4 of different lengths, thereby improving the adaptability and practicality of the clamping device 14.

[0043] Specifically, the first clamping mechanism 141 includes a first fixed seat 1411, a first lifting cylinder 1412, a first clamping piece 1413 and a first bearing 1414; the first fixed seat 1411 is located below the first box body 11, the fixed end of the first lifting cylinder 1412 is connected to the top of the first fixed seat 1411, the protruding end of the first lifting cylinder 1412 is detachably connected to the first clamping piece 1413 through the first bearing 1414, and the axis of the first lifting cylinder 1412 is perpendicular to the axis of the first clamping piece 1413; the second clamping mechanism 142 includes The second fixing seat 1421, the second lifting cylinder 1422, the first motor 1423, the second clamping member 1424, the moving seat 1425, the second track 1426 and the second cylinder 1427 are both fixedly mounted below the first box 11, the moving seat 1425 is movably mounted on the second track 1426 and the tail end of the moving seat 1425 is connected to the protruding end of the second cylinder 1427, and the second lifting cylinder 1422 is mounted on the top of the moving seat 1425 through the second fixing seat 1421. By arranging the second cylinder 1427, the second track 1426 and the moving seat 1425, the second clamping member 1424 can be driven to move along the track, thereby adapting to clamping pipelines 4 of different lengths. The first motor 1423 is installed on the top of the second lifting cylinder 1422 and the motor is detachably connected to the second clamping member 1424. The axis of the second clamping member 1424 is perpendicular to the axis of the second lifting cylinder 1422. By providing the first motor 1423, the second clamping member 1424 can be driven to rotate. Since the first clamping member 1413 is connected to the first lifting cylinder 1412 through the first bearing 1414, the first clamping member 1413 can rotate with the rotation of the second clamping member 1424, thereby driving the pipeline 4 to rotate. By providing the first lifting cylinder 1412 and the second lifting cylinder 1422, the lifting and lowering of the first clamp 1413 and the second clamp 1424 are realized. In the initial state, the first clamp 1413 and the second clamp 1424 are lowered to the bottom of the first box 11, so that the pipeline 4 can quickly enter the first box 11 from the second box 31; when spraying, the first clamp 1413 and the second clamp 1424 rise to the inside of the first box 11, thereby clamping the pipeline 4. Preferably, the first clamp 1413 and the second clamp 1424 are both conical and the vertebral bodies of the first clamp 1413 and the second clamp 1424 are arranged relative to each other, which can realize the clamping of pipelines 4 of different diameters. At the same time, the first clamp 1413 and the second clamp 1424 are detachably connected, which can be more convenient for replacement.

[0044] Furthermore, if Figure 5-Figure 8As shown, the drying device 2 includes a mounting base 21, an ultraviolet lamp tube 22, a protective cover 23 and a rotating mechanism 24; one side of the mounting base 21 is connected to the upper part of the side wall of the first box body 11 and a groove is provided on the side wall of the mounting base 21 opposite to the side wall of the first box body 11, and both ends of the ultraviolet lamp tube 22 are connected to the side walls of the groove through a connecting rod, the protective cover 23 is placed in the groove and both ends of the protective cover 23 are sleeved on the connecting rod through a rotating mechanism 24, and the rotating mechanism 24 can drive the protective cover 23 to rotate around the axis of the connecting rod to turn on or off the drying of the pipeline 4. By providing the mounting base 21, the ultraviolet lamp tube 22, the protective cover 23 and the rotating mechanism 24, the rotating mechanism 24 can drive the protective cover 23 to rotate around the axis of the ultraviolet lamp tube 22, so that during spraying, the protective cover 23 covers the ultraviolet lamp tube 22 to avoid the paint being sprayed onto the outer wall of the ultraviolet lamp tube 22 during spraying, thereby avoiding the reduction of the drying efficiency of the ultraviolet lamp tube 22; after spraying, the rotating mechanism 24 can drive the protective cover 23 to rotate, so that the protective cover 23 is hidden in the groove, so that the ultraviolet lamp tube 22 can dry the paint film on the sprayed pipeline 4; because the rotating mechanism 24 is sleeved on the connecting rod, the protective cover 23 can rotate, but the ultraviolet lamp tube 22 is fixed. Preferably, the cross-sections of the groove and the protective cover 23 are both semicircular, wherein the shape of the groove is semi-cylindrical, the shape of the protective cover 23 is a semi-cylindrical hollow structure, and the inner contour of the groove is consistent with the outer contour of the protective cover 23, which can ensure that the protective cover 23 does not interfere with the mounting base 21 when rotating around the axis of the ultraviolet lamp tube 22.

[0046] Furthermore, the rapid automatic painting system for pipelines 4 of the present embodiment further includes a grinding device 3 , which can grind the outer wall of the pipeline 4 so as to better spray the outer wall of the pipeline 4 .

[0047] Specifically, Figure 3 and Figure 4As shown, the grinding device 3 includes a second box 31, a plurality of second rollers 32 and a grinding mechanism 33; the second box 31 is provided with openings at the bottom and both ends, and the plurality of second rollers 32 are rotatably installed at the bottom of the second box 31 at intervals, so as to reduce the friction force of the pipeline 4 on the plurality of second rollers 32, so that the pipeline 4 moves more smoothly. The grinding mechanism 33 is placed inside the second box 31 and in the middle of the second box 31; the axis of the pipeline 4 is consistent with the axis of the grinding mechanism 33 and the pipeline 4 is placed flat on the plurality of second rollers 32, the axial direction of the pipeline 4 is perpendicular to the axial direction of the second rollers 32 and the pipeline 4 can pass through the grinding mechanism 33, so that the grinding mechanism 33 grinds the outer wall of the pipeline 4.

The side walls of the multiple grinding pieces 335 facing the axis of the third rotating cylinder 333 form a circle, which can better adapt to the outer wall of the pipeline 4, thereby being able to better and more efficiently grind the outer wall of the pipeline 4; the screw 336 passes through the outer wall of the third rotating cylinder 333 and the screw 336, the mounting plate 334 and the grinding piece 335 are connected in sequence. The screw 336 can be screwed into the outer wall of the third rotating cylinder 333 and move toward the axis of the third rotating cylinder 333. It can drive the grinding piece 335 to move toward the axis of the third rotating cylinder 333, thereby adapting to the grinding of pipelines 4 with different diameters, making the grinding device 3 more adaptable.

[0049] Through the above structure, the working principle of a pipeline 4 rapid automatic coating system of this embodiment is:

[0050] like Figure 1-Figure 8As shown, the system is first assembled, and then the pipeline 4 is stably placed on the multiple second rollers 32. The equipment pushes or rotates the pipeline 4 to move in a direction perpendicular to the multiple second rollers 32. At this time, the axis of the pipeline 4 is consistent with the axis of the grinding device 3; at the same time, the second motor 337 drives the second rotating drum 332 to rotate, and then drives the grinding mechanism 33 to rotate, and the grinding piece 335 in the grinding mechanism 33 also rotates around the axis of the third rotating drum 333, so that the pipeline 4 passes through the first rotating drum 331, the second rotating drum 332 and the third rotating drum 333. When the pipeline 4 passes through the third rotating drum 333, the outer wall of the pipeline 4 is polished by the multiple grinding pieces 335, so that the paint can be better adhered during subsequent painting. After the outer wall of the pipeline 4 is polished by the polishing mechanism 33 , the pipeline 4 enters the first box 11 from the second box 31 and moves along an axis perpendicular to the plurality of first rollers 12 . At this time, the first clamping mechanism 141 and the second clamping mechanism 142 are located below the first box 11 . When the pipeline 4 moves to a specific position, the first clamping member 1413 and the second clamping member 1424 are lifted due to the extension of the first lifting cylinder 1412 and the second lifting cylinder 1422, so that the tip of the cone of the first clamping member 1413 enters into the interior of the pipeline 4, and one end of the pipeline 4 is stuck on the outer wall of the first clamping member 1413. At the same time, the second clamping member 1424 is driven by the second cylinder 1427 to move along the second track 1426, driving the second clamping member 1424 to move in a direction close to the first clamping member 1413 (when the length of the pipeline 4 is too long, the second clamping member 1424 moves in a direction away from the first clamping member 1413), and the tip of the second clamping member 1424 enters into the interior of the pipeline 4, and the other end of the pipeline 4 is stuck on the outer wall of the second clamping member 1424, so that the pipeline 4 is stuck on the first clamping member 1413 and the second clamping member 1424. When the first clamping member 1413 and the second clamping member 1424 stably clamp the pipe 4, the first motor 1423 is driven to drive the second clamping member 1424 to rotate, thereby driving the pipe 4 to rotate around the axis of the pipe 4; at the same time, the spraying mechanism 13 starts to operate. According to the distance between the pipe 4 and the spray gun 131, the distance between the spray gun 131 and the pipe 4 is adjusted by the telescopic member 132, and then the pipe 4 is sprayed with paint by the spray gun 131; at the same time, the spraying mechanism is driven to reciprocate along the first track 111, so that the spraying mechanism can spray paint at various positions of the outer wall of the pipe 4 so that the paint is sprayed evenly.During the painting process, the protective cover 23 is in a state of protecting the ultraviolet lamp 22, that is, the protective cover 23 wraps the ultraviolet lamp 22; after the painting is completed, the first oil cylinder 244 extends (or retracts), driving the latch 243 to extend (or retract), thereby driving the gear 241 to rotate, and then driving the protective cover 23 to rotate around the axis of the ultraviolet lamp 22, so that the protective cover 23 is located in the groove, and the pipeline 4 is started to be dried at this time. After drying, the pipeline 4 is transported to the next working position.
