DETAILED DESCRIPTION

[0019] In order to make the purpose and advantages of the utility model more clear and obvious, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific implementation manners of the utility model, and does not strictly limit the protection range of the utility model.

[0020] like Figure 1 As shown, an automotive motor cover spraying device includes a liquid supply steel pipe 1 and a paint spray nozzle 2. The paint spray nozzle 2 is fixedly installed on the side wall of the liquid supply steel pipe 1. A protective cover 3 is slidably connected to the outer wall of the paint spray nozzle 2. A cleaning component 4 for cleaning the end of the paint spray nozzle 2 is fixedly connected to one end of the protective cover 3. Drive components 5 are symmetrically arranged on the side wall of the liquid supply steel pipe 1. One end of each drive component 5 is fixedly connected to the top of the two sides of the protective cover 3.

[0021] According to the above structure, during use, the protective cover 3 is pulled upward by the drive component 5 to expose the bottom end of the paint spray nozzle 2, and then the motor cover is painted. After the painting is completed, the protective cover 3 is driven downward by the drive component 5 to completely retract the paint spray nozzle 2 into the protective cover 3. The end of the paint spray nozzle 2 is cleaned by the cleaning component 4 to remove the paint liquid on the end of the paint spray nozzle 2, thereby avoiding the clogging of the paint spray nozzle 2 head caused by the paint drying.

[0022] like Figure 2 As shown, the protective cover 3 includes a sliding cover 31 that is slidably connected to the side wall of the paint spray nozzle 2. One end of the sliding cover 31 is fixedly connected to a cylinder 32. The middle part of the cylinder 32 is provided with an annular groove 33 for installing the cleaning component 4. The side wall of the annular groove 33 is provided with through grooves 34 that are equidistantly distributed around the axis of the annular groove 33. A sliding groove 35 is provided on one side of the sliding cover 31. The air pipe connection end of the paint spray nozzle 2 is slidably connected inside the sliding groove 35.

[0023] According to the above structure, the sliding cover 31 is fitted over the outside of the paint spray nozzle 2. When in use, the sliding cover 31 and the cylinder 32 are pulled upward. When not in use, the sliding cover 31 and the cylinder 32 are pushed downward, so that the head of the paint spray nozzle 2 retracts into the inside of the cylinder 32, thereby facilitating the cleaning of the head of the paint spray nozzle 2. When the sliding cover 31 moves, the air pipe connection end of the paint spray nozzle 2 slides inside the sliding groove 35 to avoid interference.

[0024] like Figure 2 As shown, the cleaning component 4 includes an annular tube 41 fixedly connected inside the annular groove 33. The side wall of the annular tube 41 is fixedly connected to a connecting pipe 42. Cleaning nozzles 43 are fixedly installed on the side wall of the annular tube 41 and are equidistantly distributed around the axis of the annular tube 41. Several cleaning nozzles 43 pass through several through grooves 34 respectively.

[0025] According to the above structure, when not in use, the end of the paint spray nozzle 2 is retracted into the inside of the cylinder 32. Water is introduced into the inside of the annular pipe 41 through the connecting pipe 42. Water is sprayed out through the cleaning nozzle 43 to the head of the paint spray nozzle 2 to rinse the head of the paint spray nozzle 2, thereby causing the paint liquid on the head of the paint spray nozzle 2 to fall off.

[0026] like Figure 3 and 4 As shown, the drive assembly 5 includes an extension plate 51 and a U-shaped plate 52 fixedly connected to the top of the side wall of the slide cover 31. The two ends of the U-shaped plate 52 are fixedly connected to the two sides of the extension plate 51 respectively. The liquid supply steel pipe 1 passes through the U-shaped plate 52. The top of the side wall of the extension plate 51 is symmetrically fixedly connected to a support seat 53. The top of the support seat 53 is fixedly connected to an electric actuator 54. The top of the electric actuator 54 is fixedly connected to the top of the corresponding U-shaped plate 52.

[0027] According to the above structure, when the sliding cover 31 moves, the U-shaped plate 52 is driven to move up and down by the telescopic electric push rod 54. The movement of the U-shaped plate 52 causes the extension plate 51 to move, which in turn drives the sliding cover 31, which is fixedly installed between the two extension plates 51, to move.

[0028] The working principle of this utility model is as follows: During use, the drive assembly 5 pulls the protective cover 3 upwards, exposing the bottom end of the paint nozzle 2. Then, painting is performed on the motor cover. After painting is complete, the drive assembly 5 drives the protective cover 3 downwards, causing the paint nozzle 2 to completely retract into the protective cover 3. The cleaning assembly 4 cleans the end of the paint nozzle 2, removing paint residue and preventing clogging caused by drying paint. The sliding cover 31 is fitted over the paint nozzle 2. During use, the sliding cover 31 and cylinder 32 are pulled upwards; when not in use, the sliding cover 31 and cylinder 32 are pushed downwards, causing the head of the paint nozzle 2 to retract into the cylinder 32. To facilitate cleaning of the head of the paint spray nozzle 2, when the sliding cover 31 moves, the air pipe connection end of the paint spray nozzle 2 slides inside the sliding groove 35 to avoid interference. When not in use, the end of the paint spray nozzle 2 retracts into the inside of the cylinder 32. Water is introduced into the inside of the annular pipe 41 through the connecting pipe 42. Water is sprayed out through the cleaning nozzle 43 to the head of the paint spray nozzle 2 to rinse the head of the paint spray nozzle 2, thereby causing the paint liquid on the head of the paint spray nozzle 2 to fall off. When driving the sliding cover 31 to move, the telescopic electric push rod 54 drives the U-shaped plate 52 to move up and down. The movement of the U-shaped plate 52 causes the extension plate 51 to move, which in turn drives the sliding cover 31, which is fixedly installed between the two extension plates 51, to move.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
