Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically to a coating nozzle structure. Background Technology

[0002] Coating refers to the process of applying paint to the surface of an object to form a solid film with a certain strength and continuity. Spray nozzles are used during coating.

[0003] In some existing printheads, after the painting operation is completed, some paint residue remains inside the printhead and gradually solidifies, adhering to the inner wall of the printhead. Over time, this may clog the printhead, affecting its working efficiency and potentially its service life, thus presenting certain limitations. Utility Model Content

[0004] The purpose of this invention is to provide a spray nozzle structure for coating, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a coating nozzle structure, including an outer tube, the front end of which is connected to a nozzle, and a fixing mechanism disposed at the outer end of the nozzle;

[0006] The fixing mechanism includes a connecting ring, a connecting arm, a cleaning plate, a fixing plate, and a fixing ring. A set of connecting rings is provided at the outer front end of the nozzle. At least two sets of connecting arms are provided at equal intervals at the front end of the connecting rings. A set of cleaning plates is connected to the end of each connecting arm away from the connecting ring. At least two sets of fixing plates are provided at the rear end of the connecting rings. A fixing ring is provided on the outer side of the fixing plate.

[0007] Preferably, each of the fixing plates has a set of fixing grooves at its outer middle end.

[0008] Preferably, the fixing ring can be inserted into the fixing groove, and the front end of the fixing groove is provided with an inclined surface.

[0009] Preferably, the outer side of the fixing plate is inclined.

[0010] Preferably, the outer ends of the cleaning plates are chamfered and fit against the inner side of the nozzle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The fixing mechanism located on the outside of the nozzle includes components such as a connecting ring, a connecting arm, a cleaning plate, a fixing plate, and a fixing ring. The front end of the nozzle has a connecting ring, and the front end of the connecting ring is connected to the cleaning plate through the connecting arm. The cleaning plate extends to the inside of the nozzle and fits against its inner side. By rotating the connecting ring, the cleaning plate can be rotated to cut and separate the paint solidified in the nozzle. This facilitates the removal of solidified paint and prevents the solidified paint from clogging the internal pipes of the nozzle, thus affecting the painting efficiency. It has strong practicality.

[0018] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0019] Please see Figure 1 This utility model provides a coating nozzle structure, including an external pipe 1 that can be connected to external equipment, a nozzle 2 for coating operations connected to the front end of the external pipe 1, and a fixing mechanism 3 located at the outer end of the nozzle 2.

[0020] Please see Figure 2-4This utility model provides a spray nozzle structure for painting. The fixing mechanism 3 includes a connecting ring 31, a connecting arm 32, a cleaning plate 33, a fixing plate 34, and a fixing ring 35. A set of connecting rings 31 is provided at the outer front end of the spray nozzle 2. At least two sets of connecting arms 32 are provided at equal intervals at the front end of the connecting rings 31. A set of cleaning plates 33 is connected to the end of each connecting arm 32 away from the connecting rings 31. The outer ends of the cleaning plates 33 are all chamfered and fit against the inner side of the spray nozzle 2 to facilitate the separation of solid impurities, such as solidified paint, inside the spray nozzle 2. The rear end of the connecting ring 31 is provided with no less than two sets of fixing plates 34. The outer side of the fixing plate 34 is provided with a fixing ring 35. The middle of the outer side of the fixing plate 34 is provided with a set of fixing grooves 341. The fixing ring 35 can be inserted into the fixing groove 341. The front end of the fixing groove 341 is provided with an inclined surface, which is conducive to the insertion and removal of the fixing ring 35. The outer side of the fixing plate 34 is inclined and raised from front to back. When the fixing ring 35 moves backward, it can squeeze the rear end of the fixing plate 34, so that it clamps and fits against the outside of the nozzle 2, connecting the fixing mechanism 3 to the nozzle 2.

[0021] The working principle is as follows:

[0022] In use, the fixing ring 35 can be pushed forward to remove it from the fixing groove 341 and move it to the front end of the fixing plate 34 to release the fixed connection between the nozzle 2 and the connecting ring 31. Then, the connecting ring 31 is rotated, and the cleaning plate 33 is driven to rotate inside the nozzle 2 through the connecting arm 32 to scrape off the paint solidified inside the nozzle 2, especially the paint that is stuck to the inner wall of the nozzle 2, so that it is separated from the nozzle 2 for easy cleaning.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
