[0002] Plastic spraying is a technology that uses corrosion-resistant materials on the inner walls of equipment such as metal or concrete to isolate corrosive media from the matrix equipment, thereby playing an anti-corrosion role. This technology is widely used in various fields, including household products, industrial products, and medical devices, etc. During the plastic spraying process, it is necessary to pay attention to selecting suitable paint materials and construction environments, as well as keeping tools clean and mastering spraying techniques. In addition, for different types of plastic materials and different spraying requirements, suitable plastic spraying methods and equipment need to be selected.

[0003] Currently, most common plastic spraying nozzles are straight nozzles, and the spraying direction of the nozzle can only spray forward. When the spraying part is located at the bottom or top direction of the nozzle and is parallel to the nozzle, the operator needs to spray the nozzle vertically downward or hold it up for spraying, which is laborious and inconvenient.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment:

[0024] Please refer to Figures 1-3 , this embodiment provides a nozzle for plastic spraying, including a spraying pressure handle 1. One end of the pressure spray pipe of the spraying pressure handle 1 is connected to a sleeve 2. One end of the sleeve 2 is connected to a connecting pipe 4. The outer ring surface of one end of the connecting pipe 4 is threadedly connected to a hexagonal nut 5. One end of the connecting pipe 4 is connected to a control valve 6. An adjusting cylinder 8 is rotatably connected to the outer ring surface of the connecting pipe 4 between the control valve 6 and the hexagonal nut 5. One side of the outer ring surface of the adjusting cylinder 8 is fixedly connected to a nozzle 2 10. After the hexagonal nut 5 is tightened, the adjusting cylinder 8 can be squeezed against one end of the control valve 6. During the spraying process of plastic parts, when the spraying surface of the plastic part is at the top or bottom of the spraying device and parallel to the nozzle, first loosen the hexagonal nut 5, then rotate the adjusting cylinder 8 so that the nozzle 2 10 on the adjusting cylinder 8 is perpendicular to the spraying surface of the plastic part, and then tighten the hexagonal nut 5. At this time, the operator only needs to hold the spraying pressure handle 1 horizontally to spray the plastic part, which is labor-saving and more convenient to operate.

[0025] In this embodiment, as Figure 1 and Figure 2 shown, the outer ring surface of the connecting pipe 4 is provided with an external thread, and the hexagonal nut 5 is threadedly connected to the external thread on the connecting pipe 4. After the hexagonal nut 5 is tightened clockwise, the distance between one end of it and the control valve 6 is less than the distance between the adjusting cylinders 8. Therefore, when the hexagonal nut 5 is loosened, the adjusting cylinder 8 can be released to rotate, and when the hexagonal nut 5 is tightened clockwise, the adjusting cylinder 8 can be squeezed to fix its position.

[0026] In this embodiment, as Figure 1 and Figure 2 shown, one end of the control valve 6 is connected to a nozzle 1 7. The control valve 6 rotates clockwise to open and counterclockwise to close. The spraying direction of the nozzle 1 7 is on the same line as the connecting pipe 4. When the spraying surface of the plastic part is perpendicular to the connecting pipe 4, the nozzle 1 7 can be used to spray the plastic part.

[0027] In this embodiment, as Figure 1 and Figure 2 shown, one end of the connecting pipe 4 is provided with an inner groove 401 between the hexagonal nut 5 and the control valve 6. Through holes 402 are provided in four directions on the outer ring surface of the inner groove 401. The adjusting cylinder 8 is rotatably sleeved on the outer ring surface of the inner groove 401, thereby limiting the rotation of the adjusting cylinder 8.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, sealing rings 9 are fixedly installed at both ends of the adjusting cylinder 8. The size of one end of the feed pipe of the second nozzle 10 matches the size of the through hole 402. After the second nozzle 10 rotates counterclockwise on its feed pipe, the second nozzle 10 can be closed, thereby preventing the paint from spilling out of the second nozzle 10 when the first nozzle 7 is spraying, and at the same time ensuring the sealing performance of the adjusting cylinder 8.

[0029] Working principle: When the plastic spraying nozzle is in use, when the spraying surface of the plastic part is perpendicular to the connecting pipe 4, the first nozzle 7 can be used to spray the plastic part without adjusting the angle of the nozzle. During the spraying process of the plastic part, when the spraying surface of the plastic part is at the top or bottom of the spraying device and parallel to the nozzle, first rotate the control valve 6 counterclockwise to close the first nozzle 7, then loosen the hexagonal nut 5. At this time, rotate the adjusting cylinder 8 to make the second nozzle 10 on the adjusting cylinder 8 perpendicular to the spraying surface of the plastic part, and then tighten the hexagonal nut 5. At this time, the operator only needs to hold the spraying pressure handle 1 flat to spray the plastic part, which is labor-saving and more convenient to operate.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiment is a preferred implementation scheme of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
