[0001] The present application relates to the technical field of metal tube shell spraying, and in particular to a metal tube shell spraying mechanism. Background Art
[0002] Spraying is a coating method that uses a spray gun or a disc atomizer to disperse the spray into uniform and fine droplets by pressure or centrifugal force and apply it to the surface of the object. It can be divided into air spray, airless spray, electrostatic spray and various derivative methods of the above basic spray forms, such as high-flow low-pressure atomization spray, thermal spray, automatic spray, multi-group spray, etc.
[0003] However, in practical applications, when the inner wall of most existing metal pipes is sprayed with a spray gun, it is not convenient to adjust the spray angle arbitrarily according to the actual spraying situation due to the limitation of the internal space of the metal pipe. As a result, the operation is relatively limited, and the uniformity of the spraying cannot be guaranteed, which is not conducive to promotion and use.
[0004] Therefore, those skilled in the art provide a metal tube shell spraying mechanism to solve the problems raised in the above background technology. Utility Model Content

[0011] In summary, this application includes the following beneficial technical effects:
[0012] 1. By setting the nozzle, according to the diameter of the metal tube shell, the bidirectional screw is twisted. When the bidirectional screw rotates, it drives the two L-shaped hangers to move closer to each other. After the spacing between the two L-shaped hangers is adjusted, the metal tube shell is placed on the two L-shaped hangers. At this time, the nozzle is located inside the placed metal tube shell. When the paint pump is working, the paint can be sprayed onto the inner wall of the metal tube shell using the nozzle. Compared with the manual spraying method of the spray gun, the limitations of the spraying can be effectively reduced. At the same time, the output shaft of the motor drives the transmission disk to rotate, the transmission disk drives the L-shaped hanger to rotate, and the L-shaped hanger drives the placed metal tube shell to rotate, so that the spraying can be more uniform, which is conducive to promotion and use.

The screw rod 6, when the bidirectional screw rod 6 rotates, drives the two L-shaped suspension rods 5 to move closer to each other. After the spacing between the two L-shaped suspension rods 5 is adjusted, the metal tube shell is placed on the two L-shaped suspension rods 5. At this time, the nozzle 8 is located inside the placed metal tube shell. When the paint pump 7 is working, the paint can be sprayed onto the inner wall of the metal tube shell using the nozzle 8. Compared with the manual spraying method of the spray gun, the limitations of the spraying can be effectively reduced. At the same time, the output shaft of the motor 3 drives the transmission disk 4 to rotate, the transmission disk 4 drives the L-shaped suspension rod 5 to rotate, and the L-shaped suspension rod 5 drives the placed metal tube shell to rotate, so that the spraying can be made more uniform, which is conducive to promotion and use.
[0020] In the present application, the outer sides of the two L-shaped suspension rods 5 are slidably sleeved with U-shaped limit rods 9, and the outer centers of the two U-shaped limit rods 9 are threadedly connected with extrusion bolts; by setting the U-shaped limit rods 9, when the metal tube shell is placed on the L-shaped suspension rod 5, the U-shaped limit rods 9 are manually adjusted downward, and the U-shaped limit rods 9 can be used to limit the front and rear positions of the metal tube shell to avoid falling during the rotation process, and the extrusion bolts can fix the adjusted U-shaped limit rods 9 by using the extrusion limit formed on the L-shaped suspension rod 5 to avoid displacement during use.
[0021] In the present application, the inner walls of the two transverse holes are fixedly connected with guide rods 10, and the two L-shaped suspension rods 5 are respectively slidably connected with the two guide rods 10; by setting the guide rods 10, when the L-shaped suspension rod 5 moves, the guide rods 10 can be used to limit the L-shaped suspension rod 5 to ensure that the L-shaped suspension rod 5 maintains horizontal movement to avoid deviation.
[0022] In the present application, the two L-shaped hangers 5 are both located directly above the paint box 1; by setting the L-shaped hangers 5 to be directly above the paint box 1, when the nozzle 8 sprays the paint onto the inner wall of the metal tube shell, the excess paint will slide down, and the fallen paint will drip back into the paint box 1, thereby achieving the purpose of reuse and avoiding waste.

[0025] The implementation principle of a metal tube shell spraying mechanism in the embodiment of the present application is as follows: when in use, the bidirectional screw rod 6 is twisted according to the diameter of the metal tube shell. When the bidirectional screw rod 6 rotates, it drives the two L-shaped suspension rods 5 to move closer to each other. After the spacing between the two L-shaped suspension rods 5 is adjusted, the metal tube shell is placed on the two L-shaped suspension rods 5. At this time, the spray pipe 8 is located inside the placed metal tube shell. When the paint pump 7 is working, the paint can be sprayed onto the inner wall of the metal tube shell using the spray pipe 8. Compared with the manual spraying method of the spray gun, the limitations during spraying can be effectively reduced. At the same time, the output shaft of the motor 3 drives the transmission disk 4 to rotate, and the transmission disk 4 drives the L-shaped suspension rod 5 to rotate, and the L-shaped suspension rod 5 drives the placed metal tube shell to rotate, so that the spraying can be more uniform, which is conducive to popularization and use. After the metal tube shell is placed on the L-shaped suspension rod 5, the U-shaped limit rod 9 is manually moved downward to adjust At this time, the U-shaped limit rod 9 can be used to limit the front and rear positions of the metal tube shell to prevent it from falling during the rotation process. The extrusion bolt can fix the adjusted U-shaped limit rod 9 by using the extrusion limit formed on the L-shaped suspension rod 5 to prevent displacement during use. When the L-shaped suspension rod 5 moves, the guide rod 10 can be used to limit the L-shaped suspension rod 5 to ensure that the L-shaped suspension rod 5 keeps moving in the horizontal direction to avoid deviation. The L-shaped suspension rods 5 are all located directly above the paint box 1. When the nozzle 8 sprays the paint onto the inner wall of the metal tube shell, the excess paint will slide down and the fallen paint will drip back into the paint box 1, thereby achieving the purpose of reuse and avoiding waste.
