Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0017] Example 1: This invention provides an intelligent spraying device, see [link to example]. Figures 1-4The device includes a housing 10, with a first nozzle 11 fixed to its front end. The first nozzle has a first spray chamber 11-1 inside and a first nozzle outlet 11-2 communicating with the first spray chamber at its front end. A feeding pipe 12 communicating with the first spray chamber is located inside the housing. A bypass pipe 11-3 is located near the front end of the first nozzle, communicating with the first spray chamber. The outlet of the bypass pipe faces away from the first nozzle outlet. A sealing block 11-4 is located inside the first spray chamber corresponding to the inlet of the bypass pipe. The sealing block contains magnetic material. During manufacturing, magnetic components such as iron blocks can be embedded in the sealing block, or an adhesive layer can be directly applied to the surface of the magnetic components such as iron blocks. This is well known to those skilled in the art. The details are omitted here; an electromagnet 11-5 is fixed in the first spray chamber at the position corresponding to the sealing block. In a preferred embodiment, a bypass pipe is provided on both the top and bottom surfaces of the first nozzle; support columns 11-6 are provided in the first spray chamber at the front and rear sides of the sealing block. The top end of the support column is connected to the top surface of the first nozzle, and the bottom end of the support column is connected to the bottom surface of the first nozzle. A support plate 11-7 is provided between the two support columns, and the two ends of the support columns are fixed to the corresponding support columns; the electromagnet is fixed on the support plate; a connecting plate 11-8 is connected to the front and rear sides of the sealing block, and the connecting plate is slidably connected to the corresponding support column; a spring 11-9 is provided between the connecting plate and the support plate.

[0018] In actual manufacturing, it is preferable to also provide a second nozzle 13 and a third nozzle 14 at the front end of the outer shell. The second nozzle is located above the first nozzle, and the third nozzle is located below the first nozzle. The structure of the second and third nozzles can refer to the structure of the first nozzle, except that a bypass pipe is not required. The front end of the outer shell corresponds to the position of the first nozzle with a first extension pipe 10-1. The first nozzle passes through the first extension pipe and is slidably connected to the first extension pipe and the outer shell. A first annular magnet 10-2 is fixed at the rear end of the first nozzle. The front end of the outer shell corresponds to the position of the second nozzle with a second extension pipe 10-3. The second nozzle passes through the second extension pipe and is slidably connected to the second extension pipe and the outer shell. A second annular magnet 10-4 is fixed at the rear end of the second nozzle. A partition 12-1 is fixed inside the feeding pipe. The partition is provided with a central hole 12-2, a first electromagnet 12-3, and a second electromagnet 12-4. The first electromagnet is set corresponding to the first annular magnet, and the second electromagnet is set corresponding to the second magnet. The first annular magnet can be an iron ring, an annular electromagnet, or an annular permanent magnet.

[0019] When the above-mentioned intelligent spraying device is in use, the feeding pipe 12 is used to connect the spraying material supply device. The spraying material supply device housing provides high-pressure flowing spraying material. After passing through the feeding pipe, the spraying material can provide spraying material to the first nozzle 11, the second nozzle 13 and the third nozzle 14. When spraying the product surface, under the supporting force of spring 11-9, the blocking block 11-4 blocks the bypass pipe, controls the first electromagnet 12-3 to repel the first annular magnet 10-2, and pushes the second nozzle 13 against the housing. Similarly, controls the second electromagnet 12-4 to repel the second annular magnet 10-4, and pushes the third nozzle 14 against the housing. In this way, the spraying material enters the first nozzle, the second nozzle and the third nozzle after passing through the feeding pipe and is sprayed forward. By moving the device horizontally, a relatively large area spraying operation can be completed. When spraying the product's strip groove, the first electromagnet 12-3 is controlled to attract the first annular magnet 10-2, and the second nozzle 13 slides backward until the first annular magnet contacts the first electromagnet, blocking the middle hole. Similarly, the second electromagnet 12-4 is controlled to attract the second annular magnet 10-4, and the third nozzle 14 slides backward until the second annular magnet contacts the second electromagnet, blocking the middle hole. In this way, the coating material can only enter the first nozzle after passing through the supply pipe, and is sprayed into the strip through the first nozzle. When the edge of the strip groove folds inward, the electromagnet 11-5 can be controlled to attract the blocking block, causing the blocking block to squeeze and release the blockage of the bypass pipe, and the coating material is sprayed backward through the bypass pipe. In summary, compared with existing spraying devices, this spraying device is suitable for spraying products with flat surfaces, grooves, and inwardly folded edges. It does not require multiple spraying devices to complete the above-mentioned spraying operations, making the spraying operation relatively time-saving and labor-saving.

[0020] In actual manufacturing, a valve 15 can also be installed on the feeding pipeline. The valve can be a solenoid valve or a flow control valve.

[0021] For ease of operation, an operating part 16 is provided at the bottom of the housing, wherein the operating part can be a handle or a connection part for connecting to devices such as intelligent robots.

[0022] In actual manufacturing, the end of the material supply pipe that is not connected to the first nozzle can extend to the outside of the device body to facilitate connection to the spraying material supply device.

[0023] Example 2, see Figure 6 and Figure 6Example 2 has a structure that is largely the same as Example 1, except for the arrangement of the second and third nozzles. Specifically: the second nozzle includes a second nozzle body 13-1, a second connecting pipe 13-2, and a second sleeve 13-3. The second connecting pipe penetrates the outer shell, and one end of the second sleeve is fitted onto the second connecting pipe and fixedly connected to the second connecting pipe and the outer shell. A second sphere 13-4 is provided at the rear end of the second nozzle body, and a second annular channel 13-5 is provided on the second sphere. A second inlet 13-6 communicating with the second annular channel is provided at the rear end of the second sphere, and a second outlet 13-7 communicating with the nozzle is provided at the front end of the second sphere. The other end of the second connecting pipe is fitted onto the second sphere, and a second notch 13-8 is provided at the top. A second motor capable of driving the second sphere to rotate is installed on the outer shell or sleeve. The third nozzle includes a third nozzle body 14-1, a third connecting pipe 14-2, and a third sleeve 14-3. The third connecting pipe penetrates the outer shell, and one end of the third sleeve is fitted onto the second connecting pipe 13-4. The third connecting pipe is fixedly connected to the third connecting pipe and the outer shell. A third sphere 14-4 is provided at the rear end of the third nozzle body. A third annular channel 14-5 is provided on the third sphere. A third inlet 14-6 communicating with the third annular channel is provided at the rear end of the third sphere. A third outlet 14-7 communicating with the nozzle is provided at the front end of the third sphere. The other end of the third connecting pipe is fitted onto the third sphere and has a third notch 14-8 at its bottom. A device capable of driving the third... The third motor, which rotates the sphere, is used in this structure to spray the product's strip grooves. The first motor drives the second nozzle body 13-1 to rotate counterclockwise. After rotation, the second nozzle body passes through the second notch 13-8 and becomes vertical or inclined, while the second inlet 13-6 is gradually blocked as it rotates. Similarly, the second motor drives the third nozzle body 14-1 to rotate clockwise. After rotation, the third nozzle body passes through the third notch 14-8 and becomes vertical or inclined, while the third inlet 14-6 is gradually blocked as it rotates. In this way, the coating material can only enter the first nozzle after passing through the feeding pipe.

[0024] Of course, the second and third nozzles can also be configured in other ways, as long as the following functions are achieved: In the initial state, the second and third nozzles are respectively connected to the feeding pipe, and the front ends of the second nozzle, the first nozzle, and the third nozzle are located on the same plane; the second and third nozzles are movable, such that the front ends of the second nozzle and the third nozzle are both located behind the bypass pipe; when the front ends of the second nozzle and the third nozzle are both located behind the bypass pipe, the second and third nozzles are isolated from the feeding pipe. No specific limitations are made here.

[0025] The embodiments described above are merely illustrative of implementation methods of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
