When the shapes of the pulp moldings are various, a rotating nozzle is required for spraying. The traditional rotating spraying method can spray the special-shaped pulp moldings evenly.

[0003] However, since the nozzle will drive the air flow on the periphery during rotating spraying, thereby disturbing the sprayed coating in the air. Then the coating will adhere to the surface of the sprayed part, and as a result, the coating will adhere to the exposed surfaces such as the nozzle and the support rod. And the adhered coating is difficult to clean, which will affect the overall service life. Summary of the Utility Model

Detailed implementation manners

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-6, the present utility model provides a technical solution: a pulp molding rotary spraying device, including a mounting frame 1. A motor 2 is fixedly connected to the upper end of the mounting frame 1. The output end of the lower end of the motor 2 is fixedly connected to a rotating rod 3. The rotating rod 3 is arranged inside the mounting frame 1. The rotating rod 3 at the lower end of the mounting frame 1 is fixedly connected to a connecting head 4. Both ends of the connecting head 4 are fixedly connected to support rods 5. A connecting member 6 is connected to the support rods 5. A nozzle 7 is connected to the connecting member 6. At the end of the support rod 5 near the connecting head 4, a connecting ring 8 is fixedly connected. The outer side of the connecting ring 8 is threadedly connected to a protective cover mechanism. The protective cover mechanism includes: a cover body 9. One end of the cover body 9 is fixedly connected to a mounting ring 10. The mounting ring 10 is threadedly connected to the connecting ring 8. One end of the cover body 9 is provided with a tightening opening 12. The cover body 9 is arranged outside the support rod 5, the connecting member 6 and the nozzle 7. A positioning ring 13 is fixedly connected to the cover body 9. The positioning ring 13 is magnetically attracted to the end face of the nozzle 7; The mounting frame 1 is fixed inside the spraying machine. A motor 2 is fixedly connected to the upper end of the mounting frame 1. The rotating rod 3 is driven to rotate by the motor 2. The rotating rod 3 rotates inside the mounting frame 1. The lower end of the rotating rod 3 is fixedly connected to a connecting head 4. Both ends of the connecting head 4 are fixed with support rods 5. The support rods 5 can be telescopically adjusted. The support rods 5 are of the prior art and will not be introduced in detail here. The length of the support rods 5 is adjusted according to the size of the pulp molding. A connecting member 6 is sleeved and connected to the end of the support rod 5. The connecting member 6 is tightly connected by fixing screws. A nozzle 7 is connected to the lower end of the connecting member 6. The raw material and the gas source of the nozzle 7 are connected through the outside. After the motor 2 drives the rotating rod 3 to rotate, the support rod 5 is driven to rotate. The nozzle 7 is driven to rotate by the support rod 5. The two nozzles 7 spray the pulp molding. When in use, the positioning ring 13 is first sleeved on the nozzle 7 and magnetically attracted. Then the cover body 9 wraps the support rod 5, the connecting member 6 and the nozzle 7. Then the mounting ring 10 is threadedly connected to the connecting ring 8. In this way, during spraying, the cover body 9 can prevent the paint from spraying on the surfaces of the support rod 5, the connecting member 6 and the nozzle 7. Then the tightening opening 12 is tightened. The advantage of such a design is that it is convenient for the installation and disassembly of the cover body 9, and regular replacement and maintenance can be carried out, thereby prolonging the service life.

[0024] As Figure 3 shown, the protective cover mechanism further includes: a positioning button 15. The positioning button 15 is magnetically attracted to the upper and lower ends of the connecting member 6. The positioning button 15 is arranged outside the upper and lower ends of the cover body 9 and is magnetically connected to the upper and lower ends of the connecting member 6. The positioning button 15 is magnetically attracted to the upper and lower ends of the connecting member 6. After the cover body 9 is completely covered, it is attracted to the upper and lower ends of the connecting member 6 by the positioning button 15. In this way, the cover body 9 is prevented from loosening during rotation. The positioning button 15 and the connecting member 6 clamp and fix the cover body 9.

[0025] As Figure 5As shown, a tightening rope 16 is fixedly connected to the outer end face of the support rod 5. The end of the tightening rope 16 is fixedly connected with a buckle 17. The tightening rope 16 is wound around and bundled on the outside of the cover 9. The other end of the cover 9 is fixedly connected with a through-ring 11, and the through-ring 11 is magnetically attracted to the outer end face of the support rod 5; when the through-ring 11 fixed on the cover 9 is sleeved, it passes through the buckle 17 and the tightening rope 16, and then the redundant part of the cover 9 is bound to the support rod 5 through the tightening rope 16, so as to avoid the cover 9 from loosening and fluttering when rotating.

[0026] As Figure 6 shown, a positioning block 14 is fixedly connected to the end face of the nozzle 7. The positioning ring 13 is sleeved outside the positioning block 14. The positioning block 14 is fixed on the end face of the nozzle 7. When the positioning ring 13 is magnetically attracted, it can be positioned and restricted by the positioning block 14, and similarly, the positioning ring 13 is prevented from rotating and slipping off the nozzle 7.

[0027] As Figure 5 shown, the upper end of the positioning button 15 protrudes, and the area of the magnetic attraction end face is smaller than the area of the upper and lower end faces of the connecting member 6. The upper end of the positioning button 15 protrudes, which is convenient for the operator to take, and the magnetic attraction end face of the positioning button 15 is smaller than the upper and lower ends of the connecting member 6, so that stable magnetic attraction connection can be achieved.

[0028] As Figure 5 shown, the tightening rope 16 is elastically arranged; the elastic tightening rope 16 stretches to bind the redundant part of the cover 9.

[0029] As Figure 5 shown, the cover 9 is transparent; the transparent cover 9 is convenient for external operators to observe and replace.

[0030] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to make equivalent embodiments with equivalent changes, but as long as it does not depart from the technical content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
