Description

Technical Field

[0001] This application relates to the field of spraying technology, and more specifically, to a quick paint change system. Background Technology

[0002] In the automotive painting process, the paint supply and mixing system is an important component, and its function is to deliver paint to various spraying stations.

[0003] In related technologies, the problem of paint not being recycled due to relatively short branch pipes, and the residual paint in the branch pipes being directly discharged into the waste liquid tank by compressed air, has been solved. Patent CN218962995U provides a ball-bearing rapid color-changing paint supply system. This ball-bearing rapid color-changing paint supply system performs spraying operations through a spraying unit. When the paint needs to be changed, after the previous color is sprayed, the paint in the pipe is first recycled through a ball bearing, and then double-cleaned using solvent and pure water. The pipe passes through the ball bearing, solvent, and pure water in sequence, which can effectively remove the paint adhering to the pipe wall while meeting the function of rapid color change. This avoids defects such as color difference in the paint film of the product after the system changes colors. Moreover, the elimination of branch pipes directly avoids the waste of paint in the branch pipes, saving costs from the production details.

[0004] While the existing technical solutions described above perform spraying operations through a painting unit, and when the paint color needs to be changed, after the previous color is finished, the paint in the pipeline is first recovered through a ball bearing, and then double-cleaned using solvent and pure water; the pipeline passes through the ball bearing, solvent, and pure water in sequence, which can effectively remove the paint adhering to the pipeline wall while meeting the function of rapid color change, avoiding defects such as color difference in the paint film of the product after the system changes color, and the elimination of branch pipelines directly avoids the waste of paint in the branch pipelines, thus saving costs from the production details, the following drawbacks still exist: traditional paint change systems mostly adopt manual or semi-automatic methods, the whole process is time-consuming and inefficient, and it is easy to cause paint waste and environmental pollution due to improper human operation. In addition, frequent downtime for changes also seriously affects the continuous operation capability of the production line and increases production costs.

[0005] In view of this, we propose a quick paint change system. Utility Model Content

[0006] Technical problem to be solved: The purpose of this application is to provide a quick paint replacement system, which solves the technical problems of traditional paint replacement systems, which mostly use manual or semi-automatic methods, resulting in long process time, low efficiency, and easy paint waste and environmental pollution due to improper human operation, thus increasing production costs. The system achieves the technical effect of quick paint replacement.

[0015] Beneficial effects

[0016] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0017] This application utilizes a spray nozzle, connecting pipe, rotating ring, connector, bevel gear set, and connecting rod that work together. Six sets of paint cans are installed inside the mounting rod and locking sleeve, with one end of the connector facing the center point. Rotating the rotating disc causes the connecting rod to rotate synchronously, and the bevel gear set rotates the rotating rod, which in turn rotates the mounting rod. During the rotation of the mounting rod, the paint cans rotate inside the mounting chamber. Color information on the color information panel can be observed through the viewing window, allowing the display of the required paint can color and facilitating the replacement of multiple paint cans.

[0018] This application utilizes a mounting bracket, a compression spring, a linkage rod, a connecting rod, and a mounting frame to work together. After selecting the desired color, the compression spring pushes the pull rod forward, causing the linkage rod to slide the connecting rod inside the mounting frame. This allows one end of the connecting rod to press against the bottom of the paint can, aligning the connector at the top of the paint can with the connecting pipe at the bottom of the spray head, thus completing the connection. This makes spraying more convenient and allows for quick and easy operation. Attached Figure Description

[0025] The present application will be further described in detail below with reference to the accompanying drawings. Example

[0026] Reference Figures 1-5 This application discloses a quick paint change system, comprising: an installation chamber 1, a connecting shell 101 threadedly mounted on the top of the installation chamber 1, a spray head 102 movably mounted on the top of the connecting shell 101, a pneumatic connection port 103 fixedly mounted on one side of the spray head 102, and a connecting pipe 106 extending to the connecting shell 101 fixedly mounted on the bottom of the spray head 102. A replacement mechanism 2 is provided inside the installation chamber 1, the replacement mechanism 2 including a rotating ring 201 rotatably mounted inside the installation chamber 1, and an installation clamping rod 207 rotatably mounted inside the installation chamber 1 via a rotating rod 208. Six paint cans 203 are installed on the outer side of the clamping rod 207. The top of the paint can 203 is fixedly installed with a connector 206 corresponding to the connecting pipe 106. The bottom of the installation chamber 1 is provided with a docking mechanism 3. The docking mechanism 3 includes an installation sleeve 301. An installation frame 302 is fixedly installed inside the installation sleeve 301. A docking rod 303 extending to the installation chamber 1 is slidably installed on the inner side of the installation frame 302. A shrink sleeve 308 is fixedly installed inside the installation sleeve 301. A pull rod 306 is slidably installed inside the shrink sleeve 308. The bottom of the docking rod 303 is movably connected to one end of the pull rod 306. Rotating the plum blossom disc 211 allows the connecting rod 210 to rotate synchronously. The bevel gear set 209 allows the rotating rod 208 to rotate, thereby driving the mounting clamp rod 207 to rotate. During the rotation of the mounting clamp rod 207, the paint can 203 can rotate inside the mounting chamber 1. The color information on the color information plate 204 can be observed through the observation window 205, allowing the paint can 203 of the required color to be displayed, making it convenient to replace multiple paint cans 203.

[0027] Furthermore, a connecting rod 210 is rotatably mounted inside the mounting sleeve 301. One end of the connecting rod 210 is connected to the rotating rod 208 via a bevel gear set 209. A perforated plate 211 is fixedly mounted on one end of the connecting rod 210. A linkage handle 307 extending out of the mounting sleeve 301 is fixedly mounted on the bottom of the pulling rod 306. The pulling rod 306 and the shrink sleeve 308 are movably connected via a compression spring 309. The compression action of the compression spring 309 pushes the pulling rod 306 forward, causing the linkage rod 305 to move the docking rod 303 to slide inside the mounting bracket 302. This causes one end of the docking rod 303 to press against the bottom of the paint can 203, aligning the connector 206 mounted on the top of the paint can 203 with the connecting pipe 106 mounted on the bottom of the spray nozzle 102. Example

[0028] This utility model proposes a quick paint change system. Compared to Embodiment 1, please refer to [link / reference needed]. Figures 2-5 The mounting bracket 302 and the connecting rod 303 are slidably mounted together via a sliding block 304. The pulling rod 306 and the connecting rod 303 are movably connected via a linkage rod 305. A color information plate 204 is fixedly mounted on the outside of the paint can 203, and an observation window 205 corresponding to the color information plate 204 is provided on the mounting chamber 1. The color information on the color information plate 204 can be observed through the observation window 205, allowing the display of the paint can 203 that needs to be the corresponding color, and facilitating the replacement of multiple paint cans 203.

[0029] Furthermore, a locking sleeve 202 corresponding to the paint can 203 is fixedly installed on the inner side of the rotating ring 201. The bottom of the connecting rod 303 corresponds to the bottom of the connecting joint 206. The mounting chamber 1 and the connecting shell 101 are threaded together by an internal thread 104. The outer side of the mounting chamber 1 is provided with a spiral thread 105 that mates with the internal thread 104. By rotating the plum blossom disc 211, the connecting rod 210 can be rotated synchronously. The rotating rod 208 can be rotated by the bevel gear set 209, thereby driving the mounting clamp rod 207 to rotate. During the rotation of the mounting clamp rod 207, the paint can 203 can rotate inside the mounting chamber 1.

[0030] In summary, the paint quick-change system disclosed in this application, when in use, involves installing six sets of paint cans 203 of different colors inside the mounting rod 207 and the locking sleeve 202, with one end of the connector 206 facing the center point. Rotating the swivel disc 211 causes the connecting rod 210 to rotate synchronously, and the bevel gear set 209 causes the rotating rod 208 to rotate, thereby driving the mounting rod 207 to rotate. During the rotation of the mounting rod 207, the paint cans 203 rotate inside the mounting chamber 1, and the color information on the color information plate 204 can be viewed through the observation window 205. By observing, the paint can 203 of the required color is displayed, making it easy to change between multiple paint cans 203. After selecting the required color, the pulling rod 306 is pushed forward by the squeezing action of the compression spring 309, causing the linkage rod 305 to move the docking rod 303 to slide inside the mounting bracket 302. This causes one end of the docking rod 303 to press against the bottom of the paint can 203, allowing the connector 206 installed on the top of the paint can 203 to align with the connecting pipe 106 installed at the bottom of the spray head 102, thus completing the connection. This makes the spraying process more convenient and the operation quick and easy.
