Description

Technical Field

[0001] This utility model belongs to the field of spray coating technology, and in particular relates to a cup head structure with uniform atomization. Background Technology

[0002] In the field of electrostatic spraying, the rotary cup nozzle is a key component, and its performance directly affects the spraying quality and efficiency.

[0003] Currently, existing spray cups (such as the structure described in French patent FR0506391A and Chinese patent CN110142162B) generally consist of a cup body, a core, and a rotary drive mechanism. The outer portion of the cup body mostly adopts a simple conical surface or a rounded transition, while the core is often a cylinder of uniform diameter. However, in practical applications, this type of structure suffers from problems because the core lacks taper or has insufficient taper, causing the paint to adhere to the walls prematurely under centrifugal force. This further exacerbates the unevenness of atomization, as the paint adhering prematurely cannot fully utilize the centrifugal force and airflow of the rotating cup for uniform atomization, resulting in some paint being over-atomized and others under-atomized, severely affecting the stability of the entire spraying process and the consistency of the coating quality. Utility Model Content

[0004] This invention provides a cup head structure for uniform atomization, aiming to solve the problem of uneven atomization in current cup heads.

[0005] This utility model is implemented as follows: a cup head structure with uniform atomization includes: a cup head body, the cup head body including an outer expansion cover; the outer expansion cover is provided with a liquid inlet and a spray outlet that communicate with each other; a conduit threadedly installed in the liquid inlet; a sealing nozzle assembled at the liquid inlet end of the conduit; and a diverting nozzle provided at the liquid outlet of the conduit, the diverting nozzle being provided with a nozzle.

[0006] Preferably, a connecting cylinder is fixedly installed inside the spray nozzle, and a limiting cap for limiting the nozzle is threaded onto the connecting cylinder.

[0007] Preferably, a connecting shell is threaded onto the outer wall of the outer expansion cover, and a mesh plate is provided inside the outer expansion cover.

[0008] Preferably, the diverter nozzle has a plurality of diverter holes symmetrically formed on it, and the diverter holes are connected to the internal channel of the conduit.

[0009] Preferably, the nozzle has several atomizing channels, and the limiting cover has a through groove that can accommodate the nozzle.

[0010] Preferably, the sealing nozzle has a through hole for the flow of paint.

[0012] Preferably, the mesh plate has a plurality of filter holes, and the outer expansion cover has an annular groove for limiting the position of the mesh plate.

[0013] Compared with related technologies, the cup head structure with uniform atomization provided by this utility model has the following beneficial effects: The paint is diverted and dispersed through the diversion nozzle, nozzle, diversion hole, and atomization channel. The filter holes of the mesh plate further optimize the paint distribution. Within the atomization space provided by the outer expansion cover, the structure of limiting cover and annular groove stabilizes and limits the position of each component.

[0016] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] This utility model embodiment provides a cup head structure for uniform atomization, such as... Figure 1-7 As shown, the cup head includes: a cup head body 1, the cup head body 1 including an outer expansion cover 2; the outer expansion cover 2 is provided with a liquid inlet 3 and a spray nozzle 4 communicating with each other; a conduit 5 threadedly installed in the liquid inlet 3; a sealing nozzle 6 assembled at the liquid inlet end of the conduit 5; and a diverting nozzle 7 provided at the liquid outlet of the conduit 5, the diverting nozzle 7 being provided with a nozzle 10.

[0018] In this embodiment, the sealing nozzle 6 is assembled at the liquid inlet end of the conduit 5, and then the conduit 5 is threaded into the liquid inlet 3 of the outer expansion cover 2, so that the diverting nozzle 7 is located inside the outer expansion cover 2. The paint enters the conduit 5 through the sealing nozzle 6, and after being sprayed out through the nozzle 10 of the diverting nozzle 7, it is formed into a spray by centrifugal force and airflow inside the outer expansion cover 2, and finally sprayed out from the spray port 4 to complete the coating. This cup head, with its diverter nozzle 7 and spray nozzle 10, can divert and guide the incoming paint, making it easier for the paint to be fully atomized under centrifugal force and airflow after spraying, reducing the premature adhesion of paint to the wall. The outer expansion cover 2 provides suitable space for paint atomization; compared with existing cup heads, this structural design can improve the problem of uneven atomization.

[0019] In a further preferred embodiment of the present invention, a connecting cylinder 8 is fixedly installed inside the spray nozzle 4, and a limiting cap 9 for limiting the nozzle 10 is threadedly installed on the connecting cylinder 8.

[0020] In this embodiment, the limiting cover 9 is threaded onto the connecting cylinder 8. By adjusting the position of the limiting cover 9, it limits the nozzle 10, ensuring that the nozzle 10 is in a stable position during operation. The connecting cylinder 8 provides an installation base for the limiting cover 9, and the limiting cover 9 limits the nozzle 10, which can reduce the positional displacement of the nozzle 10 caused by factors such as force, and help the paint to maintain a stable direction and state when it is sprayed from the nozzle 10, creating more stable conditions for the subsequent atomization of the paint.

[0021] In a further preferred embodiment of the present invention, a connecting shell 12 is threadedly installed on the outer wall of the outer expansion cover 2, and a mesh plate 11 is provided inside the outer expansion cover 2.

[0022] In this embodiment, the mesh plate 11 is placed inside the outer expansion cover 2, and the connecting shell 12 is threaded onto the outer wall of the outer expansion cover 2. The position of the mesh plate 11 is limited by the connecting shell 12 to ensure that the mesh plate 11 is not easily displaced during operation. The mesh plate 11 inside the outer expansion cover 2 can disperse the paint during the atomization process, making the paint particles more evenly distributed when passing through the mesh plate 11. The connecting shell 12 provides a stable installation environment for the mesh plate 11, ensuring that the mesh plate 11 can continue to function.

[0023] In a further preferred embodiment of the present invention, a plurality of diversion holes 14 are symmetrically opened on the diversion nozzle 7, and the diversion holes 14 are connected to the internal channel of the conduit 5.

[0024] In this embodiment, the diverter 7 is installed at the outlet of the conduit 5. The paint in the conduit 5 can flow out through a plurality of diverter holes 14 symmetrically opened on the diverter 7. These diverter holes 14 are connected to the internal channels of the conduit 5 and can disperse and discharge the paint. The diversion holes 14 on the diversion nozzle 7 are symmetrically distributed, allowing the paint to flow out evenly from multiple locations, avoiding uneven atomization caused by the paint being sprayed from one place. This diversion method makes it easier for the paint to be evenly affected by centrifugal force and airflow after entering the outer expansion cover 2.

[0025] In a further preferred embodiment of the present invention, the nozzle 10 is provided with a plurality of atomizing channels 13, and the limiting cover 9 is provided with a through groove that can accommodate the nozzle 10.

[0026] In this embodiment, the nozzle 10 is installed at the outlet of the conduit 5, and the limiting cap 9 is installed at the spray port 4 through the connecting tube 8. The through groove on the limiting cap 9 accommodates the nozzle 10, and the paint in the conduit 5 is sprayed out through a plurality of atomizing channels 13 on the nozzle 10. The atomizing channels 13 on the nozzle 10 can divide the paint into multiple streams, increasing the contact area between the paint and the air, which helps the paint to be better atomized under centrifugal force. The through groove of the limiting cover 9 provides installation space for the nozzle 10, and at the same time plays a certain limiting role for the nozzle 10, reducing its shaking during operation.

[0027] In a further preferred embodiment of the present invention, the sealing nozzle 6 is provided with a through hole 15 for the flow of paint.

[0028] In this embodiment, the sealing nozzle 6 is assembled at the liquid inlet end of the conduit 5. The paint can enter the interior of the conduit 5 through the through hole 15 opened on the sealing nozzle 6. The through hole 15 provides a channel for the flow of the paint. The through-hole 15 on the sealing nozzle 6 guides the paint steadily into the conduit 5, preventing leakage or diversion of the paint during entry. This design allows for a more consistent paint supply, providing a stable paint source for the subsequent atomization process.

[0029] In a further preferred embodiment of the present invention, the outer wall of the conduit 5 is provided with an external thread that matches the thread of the inner wall of the inlet 3.

[0030] In this embodiment, the conduit 5 is fitted with the thread on the inner wall of the inlet 3 through the external thread on its outer wall, and the conduit 5 is rotated to install and fix it inside the inlet 3, thus completing the connection between the conduit 5 and the outer expansion cover 2.

[0031] The external thread on the outer wall of the conduit 5 is compatible with the thread on the inner wall of the inlet 3, allowing the conduit 5 to be stably installed inside the inlet 3 and reducing the possibility of loosening or displacement of the conduit 5 during operation. This threaded connection method also facilitates the disassembly, assembly, and position adjustment of the conduit 5.

[0032] In a further preferred embodiment of the present invention, the mesh plate 11 is provided with a plurality of filter holes, and the outer expansion cover 2 is provided with an annular groove for limiting the mesh plate 11.

[0033] In this embodiment, the screen plate 11 is placed in the annular groove inside the outer expansion cover 2. The annular groove limits the position of the screen plate 11, making it difficult for the screen plate 11 to move during operation. Several filter holes on the screen plate 11 allow the paint material in the atomization process to pass through. The filter holes on the screen plate 11 can filter out larger particles in the paint and help to further disperse the paint, making the paint atomization more uniform. The annular groove inside the outer cover 2 can stabilize the position of the screen plate 11 and ensure its continuous function.

[0034] In summary, compared with related technologies, the paint is diverted and dispersed by the diverting nozzle 7, nozzle 10, diverting hole 14, and atomization channel 13. The paint distribution is further optimized by the filter holes of the mesh plate 11. Within the atomization space provided by the outer expansion cover 2, the stability of each component is limited by the limiting cover 9, annular groove, and other structures. The through hole 15 of the sealing nozzle 6 and the external thread of the guide tube 5 ensure the supply and installation of paint. This makes the cup head as a whole able to improve the problem of uneven atomization and reduce the premature adhesion of paint to the wall.
