Description

Technical Field

[0001] The utility model relates to a PVC plastic pipe plastic spraying mechanism, belonging to the field of PVC plastic pipe plastic spraying processing equipment. Background Art

[0002] Powder coating is a common surface treatment process that forms a strong and durable coating by spraying powder coating onto the surface of an object and then heating it to melt and solidify it. Existing PVC plastic pipes are sprayed with powder on the outer surface during the production process to increase the service life of the PVC plastic pipes.

[0003] Before the outer surface of the plastic pipe is sprayed, the plastic pipe needs to be fixed with internal support so that the plastic pipe is suspended inside the spray chamber to facilitate the rotation of the plastic pipe during the spraying process. However, in the internal support fixation of the plastic pipe, four sets of clamps are usually used to perform internal support fixation from the four sides of the inner wall of the plastic pipe. In the process of internal support fixation of the circular plastic pipe, since there are fewer force points for internal support fixation, deformation of the circular plastic pipe will occur during internal support fixation, thereby reducing the quality of the PVC plastic pipe spraying process.

[0004] In summary, the present invention provides a PVC plastic pipe spraying mechanism to solve the above problems. Utility Model Content

The spraying bin 3 is cylindrical with an open front. The two spraying pipe groups 4 are respectively connected to the front and rear sides of the outer cylinder surface of the spraying bin 3. The back of the inner wall of the spraying bin 3 is rotatably connected to an electric rotating shaft 6. The electric rotating shaft 6's axial surface fixing sleeve is provided with an internal support clamp 5, and the spray-molding pipe group 4 includes six feed pipes 41. The six feed pipes 41 are evenly distributed in a circle with the center of the spray-molding bin 3 as the center, and penetrate the outer cylinder surface of the spray-molding bin 3. One end of each feed pipe 41 located inside the spray-molding bin 3 is connected to an atomizing nozzle 42. Each feed pipe 41 is used to transport the spray-molding paint, and transports the paint by connecting to an external pump body and sprays the surface of the PVC plastic pipe fixed inside the spray-molding bin 3. The electric shaft 6 is a device for converting electrical energy into mechanical energy. The rotational torque generated by the motor is transmitted to the shaft, thereby driving the load in the mechanical system.

The output end of each second electric push rod 57 extends to the outside of the second octagonal seat 52 through the mounting groove 53. A second inner support plate 58 is fixedly connected between the output ends of every two adjacent second electric push rods 57. By starting each first electric push rod 54, the four first inner support plates 55 are pushed to move at the same time to expand the spacing, so that the PVC plastic tube sleeved on the outside of the inner support fixture 5 can be preliminarily supported and fixed. Then, each second electric push rod 57 is started to push the four second inner support plates 58 to move and expand the spacing. The inner tube surface of the PVC plastic tube between the two adjacent first inner support plates 55 is supported by the four second inner support plates 58, thereby increasing the contact area between the inner support fixture 5 and the inner tube wall of the PVC plastic tube, thereby improving the inner support stability of the PVC plastic tube. By starting the electric rotating shaft 6, the inner support fixture 5 is used to drive the PVC plastic tube to rotate during the spraying process, and the plastic tube fixing effect is more stable.

[0028] See also Figure 2-5 , each first inner support plate 55 is fixedly connected to a first anti-slip rubber pad 56 on one side away from the second octagonal seat 52, and each second inner support plate 58 is fixedly connected to a second anti-slip rubber pad 59 on one side away from the second octagonal seat 52, and the first anti-slip rubber pad 56 and the second anti-slip rubber pad 59 are both corrugated and concave on the side away from the second octagonal seat 52.

[0029] Specific implementation method: By placing the PVC plastic pipe to be processed into the interior of the spray molding bin 3 and sleeved on the outside of the inner support fixture 5, by starting each first electric push rod 54, the four first inner support plates 55 are pushed to move and expand the spacing, so that the PVC plastic pipe sleeved on the outside of the inner support fixture 5 can be initially supported and fixed, and then each second electric push rod 57 is started to push the four second inner support plates 58 to move and expand the spacing, and the inner tube surface of the PVC plastic pipe between the two adjacent first inner support plates 55 is supported by the four second inner support plates 58, thereby improving the internal support fixture 5 and the PVC plastic pipe. C The contact area between the inner tube wall of the plastic tube improves the internal support stability of the PVC plastic tube. By starting the electric rotating shaft 6 and using the internal support clamp 5 to drive the PVC plastic tube to rotate during the spraying process, the plastic tube fixing effect is more stable. The inner tube wall of the PVC plastic tube is internally supported and fixed from eight stress points through four first internal support plates 55 and four second internal support plates 58, so that the force during the internal support and fixation of the PVC plastic tube is more uniform, avoiding the phenomenon of round tube deformation caused by uneven internal support fixation force during the spraying process of the PVC plastic tube, and effectively improving the spraying processing quality of the PVC plastic tube.

[0031] Start the electric rotating shaft 6 and use the internal support clamp 5 to drive the PVC plastic pipe to rotate. At the same time, start the external pump body, transport the spray paint through the two spray pipe groups 4, and evenly spray the outer tube surface of the plastic pipe. The spray paint that slides down on the inner wall of the spray bin 3 will be concentrated along the arc-shaped concave bottom of the inner cylinder surface of the spray bin 3 and transported to the inside of the drain port 7, so that it can be concentratedly transported to the inside of the liquid collection box 8 for centralized collection, which effectively improves the convenience of recycling waste spray paint from PVC plastic pipes.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
