Description

Technical Field

[0001] The utility model relates to the technical field of enamel spraying, in particular to a preheating tube enamel spraying device. Background Art

[0002] Enamel spraying is a surface spraying technology that coats enamel powder on the metal surface. It can improve the corrosion resistance and wear resistance of the preheating tube and reduce its aging and damage caused by long-term high temperature, high pressure and corrosion.

[0003] At present, when spraying enamel on the preheating tube, the enamel spraying of the preheating tube is generally achieved by holding the spraying equipment and moving it along the direction of the preheating tube. However, this method is more challenging for the experience and technical level of the staff. During the spraying process, the operator needs to grasp the walking time to ensure that the surface of the preheating tube is sprayed evenly. If the speed is too fast or too slow during a period of time, it will lead to uneven spraying. At the same time, since some preheating tubes themselves have the characteristics of bending, they are very likely to deform or displace when spraying, which will lead to missing coating.

[0004] In summary, the existing preheating tube enamel spraying equipment has the following problems in actual operation:

[0005] 1) During the enamel spraying process on the preheating tube, too fast or too slow speed will cause uneven spraying of the preheating tube;

[0006] 2) Since some preheating tubes have the characteristics of bending, they are very likely to deform or displace when spraying, which may lead to coating leakage. Utility Model Content

The workbench 1 stores enamel spray material inside, and the serpentine tube 11 is stretchable to facilitate the movement of the delivery pipe 12 for spraying. A moving part 2 is provided on the surface of the workbench 1 and at one end of the delivery pipe 12, and a stretching part 3 is provided inside the workbench 1;

[0031] The moving part 2 includes a shell 21 fixed to the inside of the workbench 1. A motor 22 is installed inside the workbench 1 and on one side of the shell 21. A screw 23 is rotatably connected to the inside of the shell 21. The output end of the motor 22 passes through the inside of the shell 21 and extends to the inside of the screw 23 and is fixedly connected to it. A slider 24 is threadedly connected to the surface of the screw 23. A slide groove 25 is provided on both sides of the slider 24. The slide groove 25 is located at the top of the inner side of the shell 21 and is movably connected to it. The slider 24 extends to the top of the shell 21 and is movably connected to it. The output end of the motor 22 is movably socketed with the shell 21. The motor 22 is located inside the workbench 1 and is fixedly connected to it. At the same time, the delivery pipe 12 is located at the top of the slider 24. One end of the serpentine tube 11 is fixedly connected to one side of the delivery pipe 12 to facilitate the delivery of enamel paint.

[0032] The stretching member 3 includes a bidirectional electric push rod 31 fixed to the inner side of the workbench 1 . The output ends of the bidirectional electric push rod 31 are fixedly connected to a moving block 32 . One end of the moving block 32 is fixedly connected to a guide block 33 . The guide block 33 is T-shaped.

[0033] The stretching member 3 further includes a guide groove 34 provided on the inner side of the workbench 1 . The guide block 33 is located inside the guide groove 34 and is movably connected thereto. The guide groove 34 is also T-shaped, which can position the movable block 32 and make it more stable during movement.

[0034] The other end of the moving block 32 is fixedly connected to a U-shaped rod 35, and the other end of the U-shaped rod 35 is fixedly connected to a positioning ring 36. The positioning ring 36 is located on the surface of the workbench 1 and is oval in shape. Figure 4 As shown, a movable groove is provided at the bottom of the positioning ring 36. Figure 1 As shown, the surface of the workbench 1 is fixedly connected to a guide rod, and the movable groove is located on the surface of the guide rod and is movably connected thereto, which can increase the stability of the positioning ring 36 when it moves.

[0035] The interior of the positioning ring 36 is movably connected to a positioning arc plate 38, and the top of the positioning arc plate 38 is rotatably connected to a bolt 39. One end of the bolt 39 extends to the top of the positioning ring 36 and is threadedly connected to it. The bolt 39 is used to drive the positioning arc plate 38 to fix the preheating tube. At the same time, the inner side of the positioning arc plate 38 is installed with equidistantly arranged arc-shaped rubber strips, which can facilitate the fixation of the preheating tube.

The limiting blocks 381 are located inside the limiting groove 37 and are movably connected thereto, thereby ensuring the stability of the positioning arc plate 38 when it moves.

[0037] When in use, place the two ends of the preheating tube inside the positioning ring 36 respectively, and at the same time rotate the bolt 39 to push the positioning arc plate 38 through the limit blocks 381 on both sides thereof and descend along the limit groove 37 inside the positioning ring 36 until the preheating tube is fixed;

[0038] Then, by starting the bidirectional electric push rod 31, it pushes the two sets of moving blocks 32 to move slowly along the inside of the guide groove 34 through the guide block 33 and move toward the two ends of the workbench 1, so that the two sets of driving positioning rings 36 are moved away from each other until the preheating tube is pulled into a straight state;

[0039] Then, the motor 22 is started to drive the screw 23 to rotate and the slider 24 to move horizontally. At the same time, the enamel is sprayed on the surface of the straightened preheating tube through the nozzle 13. In this process, the stability of the nozzle 13 during movement can be maintained, and the uniformity of the enamel spraying on the preheating tube can be ensured, thereby avoiding the difficulty in maintaining speed balance during manual operation and the uneven spraying on the preheating tube.
