Description

Technical Field

[0001] The utility model relates to the field of spraying operations, in particular to a nozzle cleaning device. Background Art

[0002] The nozzle is a key component in many types of spraying, atomizing, oil spraying, sandblasting, spraying and other equipment. However, after the spraying operation is completed, the spraying liquid often does not flow and dries on the nozzle surface, so the nozzle needs to be cleaned. If it is not cleaned, the nozzle will often be blocked. After the blockage, the spraying operation cannot continue. If the blockage is serious, the nozzle needs to be replaced. This will directly increase the economic cost of the enterprise and affect production efficiency.

[0003] The existing cleaning method often adopts manual cleaning. Manual cleaning requires the nozzle to be disassembled, and the cleaning liquid is manually inverted on the surface of the nozzle. The nozzle is continuously wiped with a tool to wipe the paint on the nozzle. After wiping, the nozzle is installed on the equipment. The whole process is very cumbersome, and the cleaning process takes a long time, which is not conducive to production. At the same time, it will increase the workload of the operators. At the same time, paint is a harmful substance. Long-term manual cleaning will cause great harm to human health. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations:

[0021] like Figure 1 , 2As shown in Figures 3 and 4, a nozzle cleaning device comprises a manipulator 1, a support frame 2 is connected to the wrist end of the manipulator 1, a nozzle 3 for spraying operation is fixedly connected to the support frame 2, a rotatable cleaning device is arranged on one side of the nozzle 3, the cleaning device comprises a cleaning box 4 with an opening on one side, a turntable 9 is arranged in the cleaning box 4, a brush 10 is arranged on the outside of the turntable 9, a rotating shaft 12 is arranged at the center of the turntable 9, the rotating shaft 12 extends to the outside of the cleaning box 4 and is synchronously driven and connected with the output shaft of the driving motor 6.

[0022] like Figure 4 As shown, the cleaning box 4 and the support frame 2 are connected and fixed via a guide rail type door closer 7.

[0023] like Figure 4 As shown, the cleaning box 4 is provided with a central axis on both upper and lower sides.

[0024] like Figure 4 As shown, two support rods 13 are arranged on one side of the support frame 2, and a cleaning box 4 is rotatably supported between the support rods 13 and is hinged and fixed to the central axis.

[0025] like Figure 2 , 5 As shown, a water outlet 14 is provided at the upper portion of the cleaning box 4, to which a water supply assembly is connected, and a water receiving trough 11 is provided at the lower portion of the cleaning box 4, to which a drain pipe 17 is connected in the middle.

[0026] like Figure 1 , 3 As shown in FIG. 4 , the water supply assembly includes a water pipe 8 connected to the water outlet. The water pipe 8 is connected and fixed to an external water supply tank via a booster pump 15 . A control valve 16 is installed on the water pipe 8 .

[0027] like Figure 1 , 3 As shown in Figure 4, the water pipe 8 is made of a ductile rubber hose.

[0028] The implementation principle of a nozzle cleaning device in the embodiment of the present application is:

[0029] When cleaning the nozzle 3, the guide rail door closer 7 is started, and the guide rail door closer 7 will rotate the cleaning box 4 along the circumferential direction of the central axis 41 to cover the nozzle 3, and the brush 10 will fit closely with the nozzle 3;

[0030] After the cleaning box 4 covers the nozzle 3, the driving motor 6 is started. When the driving motor 6 rotates, the rotating disk 9 is driven to perform circular motion through the rotating shaft 12. At the same time, the brush 10 rotates continuously on the surface of the nozzle 3. During the rotation, the booster pump 15 is started to open the control valve 16, and the cleaning liquid is discharged from the water outlet 14 to the nozzle 3 through the water pipe 8 to ensure the humidity of the nozzle 3 surface. When the brush 10 rotates continuously on the surface of the nozzle 3, the paint on the nozzle 3 is wiped off. At the same time, the wiped liquid is thrown onto the side wall of the cleaning box 4 as the rotating disk 9 rotates, flows into the water receiving tank 11 along the side wall, and flows into the external waste liquid collection place from the drain pipe 17 at the bottom of the water receiving tank 11, thereby completing a cleaning work. The whole process saves time and effort, better avoids a series of problems caused by manual cleaning, and better improves production efficiency.

[0031] When spraying is performed, the guide rail door closer 7 is started, and the cleaning box 4 is rotated to one side of the nozzle 3, and then the spraying operation can be performed.
