[0036] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] First of all, in the spraying equipment, the spray gun is a core component, which is mainly composed of a spray cap, a nozzle, a needle valve and a gun body. If it is not cleaned in time after use, the spray cap, the nozzle and other components are very likely to be clogged due to paint residue; in the past spraying industry, spray gun cleaning was done manually by manual disassembly and cleaning, but this was time-consuming and the effect was poor, so there are endless equipment for cleaning spray guns (for example, a spray gun cleaning machine shown in publication number CN207805861U) to assist in cleaning, but the existing spray gun cleaning machines also have poor cleaning effect and low cleaning efficiency.

[0039] In view of this, please refer to Figure 1 and Figure 2 The schematic diagram of the overall and partial structures (excluding the main housing and the bottom plate) of a spray gun cleaning machine provided by this embodiment is shown, and the spray gun cleaning machine includes:

[0040] A shell body 1, wherein an opening 2 is formed at the top of the shell body 1;

[0041] A cleaning component, which is arranged inside the housing 1;

[0042] The cleaning assembly includes a brush 3 and a cleaning part that cooperate with each other. The cleaning part and the brush 3 are both arranged in cooperation with the opening 2. The cleaning part is used to spray cleaning agent on the brush 3; the brush 3 is used to clean the spray gun extending into the shell 1 through the opening 2.

[0043] In this embodiment, the cleaning assembly is a main component for cleaning the spray gun. At the same time, since the spray gun is easily blocked at the spray gun head, the spray gun head is cleaned in this embodiment. Specifically, the spray gun head can be extended into the shell 1 through the opening 2 at the top of the shell 1, and the spray gun is cleaned by the cleaning part and the brush 3. At this time, in order to enhance the cleaning effect of the spray gun, the cleaning part sprays the cleaning agent to the brush 3, and then the brush 3 cleans the spray gun, which greatly improves the cleaning effect of the spray gun.

[0044] In a preferred embodiment, if Figure 3 As shown, the cleaning assembly further includes: a cleaning bracket 4, which is disposed in the housing 1; the cleaning bracket 4 includes: two support panels 41 and a middle panel 42 disposed between the two support panels 41; a brush 3 is disposed between the middle panel 42 and one of the support panels 41;

[0045] The cleaning bracket 4 is an integrated bracket, which can be directly placed inside the shell 1 , and a brush 3 is also arranged thereon, so when the brush 3 needs to be maintained at a later stage, the brush 3 can be directly maintained by taking out the cleaning bracket 4 .

[0046] The driving member 5 is arranged on one side of the housing 1; the driving end of the driving member 5 extends into the housing 1 and is in transmission connection with the brush 3, and is used to drive the brush 3 to swing, so as to clean the spray gun more comprehensively. The driving member 5 is selected as a swing cylinder, and a protective shell 20 is arranged outside the driving member 5, and a valve interface for supplying gas required by the driving member 5 is arranged on the protective shell 20 (see Figure 4 ). It should be noted that the setting of the valve interface depends on the type of the driving member 5, which is selected as a swing cylinder, so that the cleaning machine can have an explosion-proof function and can be used in places with a higher explosion-proof level to avoid safety hazards and unnecessary risks.

[0047] In a preferred embodiment, as 3 and Figure 4 As shown, the cleaning unit includes:

[0048] A spraying bracket 6, which is arranged inside the housing 1; a spraying valve 7 is arranged on the spraying bracket 6, and a spraying pipe 8 is connected to the spraying valve 7;

[0049] The input end of the spray valve 7 passes through the housing 1 and extends to the outside of the housing 1 . The output end of the spray pipe 8 is arranged corresponding to the brush 3 for spraying cleaning agent to the brush 3 .

[0050] Among them, the type of spray gun valve 7 can be selected as a three-way valve, in which the air inlet (equivalent to the input end) passes through the shell 1 and extends to the outside of the shell 1, and is used to be connected to an external container storing a cleaning agent through a pipeline, and the remaining two air outlets (equivalent to the output end) can be respectively connected to different pipelines and valve bodies located on both sides of the brush 3 (for example, a one-way valve is selected). In this way, the cleaning part can spray the cleaning agent to both sides of the brush 3 at the same time.

[0051] In a preferred embodiment, if Figure 2 or Figure 3 As shown, the cleaning part further includes: a travel rod 9, which is disposed between two support panels 41; the travel rod 9 is connected to a moving plate 10 via a slidable sleeve 91; the moving plate 10 is located above the brush 3;

[0052] In order to ensure stable movement of the moving plate 10, two travel rods 9 can be selected and both are arranged in parallel; two sliding sleeves 91 are slidably arranged on the two travel rods 9, and the four sliding sleeves 91 are evenly distributed on both sides of the moving plate 10 to jointly drive the moving plate 10 to move.

[0053] An elastic member 11 is provided between the sliding sleeve 91 and the supporting panel 41 on the side close to the driving member 5; the moving plate 10 can slide along the extending direction of the travel rod 9;

[0054] The type of the elastic member 11 can be a spring, which is arranged between the sliding sleeve 91 and the supporting panel 41 on the side close to the driving member 5. The setting of the elastic member 11 can ensure that the movable plate 10 maintains a stable posture and does not slide at will when it is not pushed by any external force. At the same time, since the movement of the movable plate 10 will compress the elastic member 11, when you want to reset the movable plate 10, the elastic member 11 will also speed up the resetting speed of the movable plate 10.

[0055] In addition, if Figure 1 or Figure 2 As shown, the movable plate 10 is provided with a spray gun fixing port 101, which is located in the opening 2; the spray gun fixing port 101 moves in the opening 2 as the movable plate 10 slides. The spray gun fixing port 101 is used to accommodate and support the spray gun head. When the spray gun fixing port 101 arrives above the brush with the movable plate 10, the brush 2 can clean it. The specifications of the spray gun fixing port 101 need to match the spray gun to be cleaned.

[0056] In a preferred embodiment, if Figure 3 As shown, a leak bucket 12 is also provided on the cleaning bracket 4. The leak bucket 12 is located on the side of the middle panel 42 away from the brush 3 and below the movable plate 10. A flow channel is formed in the leak bucket 12 for discharging sewage used for cleaning the spray gun.

[0057] The leaky bucket 12 can be set on the cleaning bracket 4 by an extended edge of the leaky bucket 12. When selected, the leaky bucket 12 can be slightly larger than the spray gun head. After the spray gun is cleaned, the movable plate 10 can stay above the leaky bucket 12 to discharge the sewage left on the spray gun or the clean water after cleaning from the leaky bucket 12 to the outside of the shell 1.

[0058] In a preferred embodiment, if Figure 3 As described above, in order to achieve cleaning and drainage of the spray gun, the opening 2 extends from above the leak bucket 12 to above the brush 3;

[0059] At this time, the movable plate 10 has a first station and a second station; when the movable plate 10 is located at the first station, the spray gun fixing port 101 is located above the leak bucket 12; when the movable plate 10 is located at the second station, the spray gun fixing port 101 is located above the brush 3.

[0060] For the convenience of the entire cleaning process, when the movable plate 10 is located at the first working position, the elastic member 11 is in a natural state, so when the movable plate 10 is not subjected to external force, it can be maintained above the leak bucket 12; if the spray gun needs to be cleaned, the spray gun head needs to be placed at the spray gun fixing port 101. At this time, pushing the spray gun can drive the movable plate 10 to move, and the elastic member 11 will be compressed. The movable plate 10 will also move along the stroke rod 9. When the spray gun fixing port 101 reaches above the brush 3, stop pushing the spray gun.

[0061] It should be noted that in the embodiments of the present application, a robot is generally used to place and move the spray gun, so the insertion depth and stop position of the spray gun are completed by the robot according to the instructions set in advance by the technician.

[0062] In a preferred embodiment, if Figure 1 As shown, a raised edge 102 is formed at the spray gun fixing port 101 , and the raised edge 102 is used to fix the spray gun and cooperate with the edge of the opening 2 to constrain the travel of the moving plate 10 in the opening 2 .

[0063] The raised edge 102 is essentially inclined, and the transverse cross-section of the raised edge 102 gradually increases from close to the movable plate 10 to away from the movable plate 10, thereby playing a certain supporting and limiting role for the spray gun, ensuring that the spray gun will not fall directly from the spray gun fixing port 101.

[0064] In addition, the raised edge 102 is also higher than the shell 1, so during the movement of the spray gun fixing port 101, the raised edge 102 will engage with the opening 2 to stop the moving plate 10 from moving, thereby restricting its travel.

[0065] In a preferred embodiment, a blowing portion 13 is disposed on the top of the shell 1, and the blowing portion 13 is located at the opening 2. The blowing portion 13 is provided with a plurality of blowing holes 131, and the blowing holes 131 are used to blow air to the spray gun.

[0066] The blowing part 13 is provided with a general air source interface. When the air source interface is connected to an external air source, the cleaned spray gun in the spray gun fixing port 101 can be blown dry through the multiple blowing holes 131 on the blowing part 13, so that the spray gun can be put into use as soon as possible.

[0067] In a preferred embodiment, if Figure 1 and Figure 5 As shown, the housing 1 includes a top cover plate 14, a main housing 15 and a bottom plate 16; the top cover plate 14 and the main housing 15 are movably connected; the bottom plate 16 is composed of two inclined plates, and the two inclined plates form an angle with the opening facing the top of the housing 1;

[0068] The bottom plate 16 is also provided with a main leakage bucket 17 penetrating therethrough. The port of the main leakage bucket 17 is flush with the end surface of the bottom plate 16 and is provided corresponding to the leakage bucket 12 . The caliber of the main leakage bucket 17 is larger than that of the leakage bucket 12 .

[0069] Specifically, the top cover 14 and the main housing 15 are in a flip-up active connection, which is equivalent to the top cover 14 being directly opened by a handle 19 provided thereon; the bottom plate 16 is composed of two inclined plates to form a V-shaped structure (see details). Figure 5 ), during use, it is convenient to discharge the waste liquid after cleaning the spray gun from the main leakage barrel 17 outside the shell 1, which effectively solves the problem of waste liquid residue caused by the flat bottom structure, and does not require personnel to frequently clean and maintain, thereby improving work efficiency; the main leakage barrel 17 is equivalent to opening a through hole in the bottom plate 16, and a barrel-shaped structure extends below the through hole, so the port of the main leakage barrel 17 is equivalent to being flush with the end surface of the bottom plate 16.

[0070] It should be noted that in order to speed up the discharge of the waste liquid remaining on the spray gun, the bottom of the leakage bucket 12 can be extended to a certain distance inside the main leakage bucket 17, but a gap needs to be left between the two to ensure that the waste liquid in the shell 1 is discharged smoothly.

[0071] In a preferred embodiment, if Figure 1 , Figure 2 or Figure 3 As shown, a telescopic support frame 18 is also provided at the bottom of the housing 1, and the telescopic support frame 18 is used to adjust the height of the housing.

[0072] The telescopic support frame 18 can make the overall height of the spray gun cleaning machine adjustable. Specifically, the telescopic support frame 18 can adopt a two-stage plug-in and telescopic structure. When in use, the height is adjusted according to the on-site conditions and then locked and fixed by the locking bolts, which can meet the use under different working conditions and heights.

[0073] Based on the above description, the embodiment of the present application proposes a spray gun cleaning machine, and its specific working principle is as follows:

[0074] The cleaning robot places the head of the spray gun to be cleaned into the spray gun fixing port 101 and pushes the spray gun, controls the movable plate 10 to drive the spray gun head to move to the second station, that is, to the top of the brush 3. At this time, the spray valve 7 will spray the cleaning agent to the brush 3 through the nozzle 8, and the brush 3 will swing under the control of the driving part 5 to comprehensively clean the spray gun head.

[0075] After cleaning is completed, the movable plate 10 can be quickly reset to the first working position with the assistance of the elastic member 11, that is, back to the top of the leak bucket 12. At this time, the waste liquid remaining at the head of the spray gun can be discharged from the shell 1 through the leak bucket 12 and the main leak bucket 17; at the same time, the external air source can be started at this time to make the blowing hole 131 blow air to the spray gun to accelerate the drying speed of the spray gun.

[0076] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
