[0054] For a better understanding of the technical solution of this utility model, please refer to... Figure 1 and Figure 2To address the issues of poor corner cleaning and paint / solvent residue when using a single-layer rotating nozzle in a rapid color-changing cleaning process, this invention proposes a spraying equipment cleaning device 1, comprising: a paint container 10, multiple spraying components 2, a first pipeline 3, a second pipeline 4, and a control device 7; the multiple spraying components 2 are arranged in layers inside the paint container 10, including a sprayer 21 and a first fastener 22; the first pipeline 3 connects to the sprayer 21 and delivers cleaning solvent to the sprayer 21; the second pipeline 4 delivers compressed air and connects to the first pipeline 3; the control device is connected to the first and second pipelines and controls the transmission of cleaning solvent and / or compressed air; wherein, the first fastener 22 connects the sprayer 21 to the first pipeline 3 and fixes the sprayer 21 in a cleaning direction, which is any direction perpendicular to the axis of the first pipeline 3 corresponding to the sprayer 21. In one embodiment, the solvent supply device 5 and the compressed air supply device 6 provide solvent and compressed air for cleaning to the first pipeline 3 and the second pipeline 4, respectively. The first pipeline 3 enters the paint container 10 through a solvent inlet located on the side wall of the paint container 10. The second pipeline 4 is divided into a first part located outside the paint container 10 and a second part located inside the paint container 10. The second part of the first pipeline 3 connects to the sprayers 21 of multiple spraying components 2 arranged in layers inside the paint container 10, and provides solvent and compressed air to the multiple sprayers 21 to perform three-dimensional cleaning of multiple areas inside the paint container 10. In one embodiment, the control device 7 can be a switch device for manual operation by the operator, or it can be an automatic control device composed of a microprocessor. In one embodiment, the first pipeline 3 can be fixed inside the paint container by a retaining ring and a screw or nut, or by welding, and is not limited thereto. Multiple spraying components 2 are fixed to the first pipeline 3 by first fasteners 22, thereby arranging multiple spraying components 2 in layers inside the paint container.
[0055] Please see Figure 3 and Figure 4 In one embodiment, for the layered sprayers 21, when a layer includes multiple sprayers 21, the multiple sprayers 21 are symmetrically arranged around the geometric center of the layer containing the paint container. In another embodiment, the layered sprayers do not overlap in the height direction of the paint container. The beneficial effect of this embodiment is that it provides three-dimensional cleaning of multiple areas inside the paint container 10, resulting in a good cleaning effect.
[0056] In one embodiment, three spraying components 2 are symmetrically arranged at the center of the upper layer A for cleaning the upper part of the paint container and its lid; three spraying components 2 are symmetrically arranged at the center of the middle layer B for cleaning the middle part of the paint container and the shaft of the agitator; and one spraying component 2 is arranged in the lower layer C for cleaning the lower part of the paint container and the agitator. The multiple spraying components 2 are staggered within the paint container 10 at angles such as... Figure 4 As shown, this allows for uniform cleaning from multiple angles, resulting in better cleaning performance. Those skilled in the art will understand that multiple spraying components 2 can be arranged in layers and staggered within the paint container 10, with more or fewer layers as needed. The staggered angles can also be varied and are not limited to this. Furthermore, the shape of the paint container 10 is not limited to a cylindrical shape. In one embodiment, the spraying components 2 arranged in the upper layer A, middle layer B, and lower layer C do not overlap in the height direction of the paint container; in other embodiments, the spraying components 2 may overlap in the height direction of the paint container.
[0057] Please see Figure 5 In one embodiment, the spraying assembly 2 further includes a second fastener 23, which is used to further secure the first fastener 22, the first pipeline 3, and the sprayer 21. The sprayer 21 includes a nozzle 211 and a three-way connector 212. The first fastener 22 can be a retaining sleeve or a retaining ring, and is fixedly connected to the first pipe 3 via the three-way body 212 of the sprayer 21. The first fastener 22 can rotate 360 degrees around the axis of the first pipe 3. Therefore, during the cleaning and debugging phase, the angle between the first fastener 22 and the axis of the first pipe 3 can be adjusted to change the spraying position of the sprayer 21. After determining the spraying position of the sprayer 21, the first fastener 22 is then tightened to the three-way body 212 of the sprayer 21 (this tightening method can be by further tightening the retaining ring or retaining sleeve, or by applying pressure to the retaining ring or retaining sleeve to increase the contact area with the three-way body 212, etc.). The first fastener 22 can also be other types of fasteners, as long as they can fix the sprayer 21 to the first pipe 3 and can rotate around the axis of the first pipe 3. This invention is not limited to these types. Furthermore, the first fastener 22 allows the sprayer 21 to be adapted to more sizes of first pipes 3. In one embodiment, the second fastener 23 can be threaded or clamped to the first fastener 22 to further strengthen the fixing strength between the first fastener 22, the sprayer 21, and the first pipeline 3. In one embodiment, the sprayer 21 also includes a three-way pipe 213 in the three-way body 212, which can protect the three-way body 212 and extend its service life.
[0058] In one embodiment, the second fastener 23 has a protrusion 231, and the first fastener 22 has a recess 221, with the protrusion 231 corresponding to the recess 221. The snap-fit connection between the second fastener 23 and the first fastener 22 facilitates installation.
[0059] In one embodiment, such as Figure 1 As shown, the control device 7 is a programmable logic controller (PLC). The PLC is connected to the first pipeline 3 and the second pipeline 4 through the solvent supply device 5 and the compressed air supply device 6, and controls the transmission of cleaning solvent and / or compressed air. PLC pulse control of the solvent and compressed air transmission can further save solvent.
[0060] In one embodiment, the paint container 10 is provided with a container lid, a stirring part, and a stirring shaft. The container lid is located on the top of the main body of the paint container 10, and the stirring part and stirring shaft are connected inside the paint container.

In one embodiment, the container lid of the paint container 10 is also provided with a siphon pipe and a return pipe. When cleaning the container lid, the spraying equipment cleaning device 1 can simultaneously clean the siphon pipe and the return pipe.
[0061] In one embodiment, the paint container 10 further includes at least one exhaust vent 12 located on the side wall.
[0062] In one embodiment, the paint container 10 further includes at least one waste liquid discharge hole 11 located at the bottom of the side wall.
[0063] In one embodiment, the inner bottom surface of the paint container 10 has an inclined angle θ relative to the outer bottom surface of the paint container 10. Through the above design of the paint container 10, waste liquid and waste gas can be automatically discharged while the paint container 10 is being cleaned, without the need for manual intervention.
[0064] In one embodiment, the lowest point of the inner bottom surface of the paint container 10 is connected to the waste liquid discharge hole 11, so that all the waste liquid can be discharged from the waste liquid hole and will not remain in the paint container barrel.
[0065] In one embodiment, the aforementioned spraying equipment cleaning device 1 can be applied to a rapid color-changing spraying system. After the paint-containing bucket lid and its components are cleaned online or offline by the paint container 10, the cleaned bucket lid and its components, together with the paint, are conveyed to the spraying device for spraying operations by the color-changing component. The spraying equipment cleaning device 1 is used to clean the container lid, siphon pipe, and return pipe provided on the paint container 10, as well as the stirring part and stirring shaft inside the paint container. In this embodiment, the spraying device and color-changing component are conventional equipment in the art and will not be described in detail. It should be noted that the aforementioned spraying equipment cleaning device 1 can also be applied to other types of spraying operation systems, and is not limited thereto.
