Description

Technical Field

[0001] The utility model relates to the technical field of spray gun cleaning equipment, in particular to a spray gun cleaning equipment for a brazing flux spraying production line. Background Art

[0002] Brazing flux refers to the flux used in brazing. Its function is to remove oxides on the surface of the base material and the brazing filler metal. It is usually sprayed onto the surface of the base material with a spray gun before brazing. However, since the brazing flux is easily formed into atomized particles after being atomized by the spray gun, it is easy to cause damage to the spray gun if it is not cleaned in time. Therefore, after the spray gun has been used for a long time, it usually needs to be cleaned with a cleaning equipment.

[0003] However, when the existing spray gun is cleaned in the equipment, usually only the flux mist covering the outer surface of the spray gun is flushed, and the residual flux inside the spray gun cannot be cleaned synchronously. As a result, when the flux inside the spray gun is subsequently cleaned, the flux flushed out is likely to flow to the outer surface of the spray gun again, resulting in the flux on the spray gun not being cleaned thoroughly. In addition, when cleaning the existing flux spray gun, a high-speed water flow is usually used for flushing. However, since the spray gun cannot be well fixed during flushing, the water flow inside the spray gun is likely to rush to the inner wall of the equipment when flushing, resulting in secondary splashing, which makes it impossible to centrally collect the wastewater generated after flushing and carry out subsequent harmless treatment. Utility Model Content

[0004] The purpose of the utility model is to provide a spray gun cleaning device for a brazing flux spraying production line to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spray gun cleaning device for a flux spraying production line, comprising a shell, a horizontal tube fixedly installed on the top of the inner side of the shell, a plurality of nozzles fixedly installed on the bottom end of the horizontal tube, a hose movably connected to one end of the horizontal tube, a docking joint provided on the bottom end of the hose, a movable plate movably embedded in the inner side of the shell, a wire mesh embedded in the top end of the movable plate, a support frame fixedly connected to the middle part of the wire mesh, a spray gun placed on the top end of the support frame, a cover tube provided on one side of the spray gun, a guide pipe passing through the bottom end of the cover tube, a wastewater chamber provided at the bottom of the inner side of the shell, and a wastewater pipe passing through the bottom of one side wall of the shell.

[0006] Preferably, a water pump is fixedly mounted on one side of the top end of the housing, a water pipe is engaged with the output end of the water pump, and the end of the water pipe is engaged and connected with the horizontal pipe.

[0007] Preferably, the output end of the water pump is provided with a mixing box, and the top of the mixing box is movably connected to a solvent cartridge.

[0008] Preferably, a water inlet pipe passes through one side wall of the mixing box, and the water inlet pipe communicates with the interior of the water pump through the mixing box.

[0009] Preferably, a transparent plate is engaged with one side of the top end of the movable plate, and the transparent plate is movably connected to the shell.

[0010] Preferably, electric push rods are fixedly mounted on the middle portions of both side walls of the shell, and the output ends of the two electric push rods are respectively engaged and connected with the docking joint and the cover tube.

[0011] Preferably, the docking joint and the cover tube are movably connected to the gun tail and the nozzle of the spray gun through an electric push rod respectively.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The flux spraying production line uses a spray gun cleaning equipment. Through the horizontal pipe, nozzle, hose and joint, water flows into the outer surface and the inside of the flux spray gun, so that the inside and the outer surface of the spray gun can be flushed by water simultaneously, thereby avoiding the flux residue on the spray gun caused by the internal and external cleaning steps, which is conducive to cleaning the flux on the spray gun.

[0014] 2. The flux spraying production line uses a spray gun cleaning equipment, which passes through the cover tube, guide tube, wire mesh and wastewater chamber. When the inside of the spray gun is being flushed, the water flowing out of the spray gun will flow along the cover tube and guide tube to the wire mesh, making it difficult for the wastewater generated during the spray gun flushing to produce secondary splashes. At the same time, the wastewater chamber can receive the wastewater flowing down from the wire mesh, so that the wastewater generated during the flushing can be collected centrally and discharged to the treatment equipment through the wastewater pipe for subsequent harmless treatment.

[0023] like Figures 1 to 4As shown, the spray gun cleaning equipment for the flux spraying production line of this embodiment includes a shell 1, a horizontal pipe 12 is fixedly installed on the top of the inner side of the shell 1, and a plurality of nozzles 20 are fixedly installed on the bottom end of the horizontal pipe 12. A hose 13 is movably connected to one end of the horizontal pipe 12, and a docking joint 14 is sleeved on the bottom end of the hose 13. A movable plate 9 is movably embedded in the inner side of the shell 1, a wire mesh 10 is embedded in the top of the movable plate 9, and a support frame 16 is fixedly connected to the middle of the wire mesh 10. A spray gun 15 is placed on the top of the support frame 16, and a cover tube 18 is provided on one side of the spray gun 15. A guide tube 19 is passed through the bottom end of the cover tube 18. A wastewater chamber 17 is opened at the bottom of the inner side of the shell 1, and a wastewater pipe 11 is passed through the bottom of one side wall of the shell 1.

[0024] The cleaning fluid of the nozzle 20 at the bottom end of the horizontal pipe 12 can be sprayed on the outer surface of the spray gun 15 on the support frame 16, thereby facilitating the flushing of the residual flux on the outer surface of the spray gun 15. The function of the hose 13 is to allow the high-speed water flow in the horizontal pipe 12 to flow into the docking joint 14, so that the water nozzle of the docking joint 14 can also spray high-speed water flow. The water nozzle at the end of the docking joint 14 can be docked with the connecting hole of the tail of the spray gun 15 under the action of the electric push rod 7, so that the water flow in the docking joint 14 can rush into the interior of the spray gun 15. The movable plate 9 can be pulled out from the opening on the front of the shell 1, thereby facilitating the placement of the spray gun 15 on the support frame 16. The function of the wire mesh 10 is to allow the movable plate 9 to The waste water generated during flushing can be passed into the waste water chamber 17 at the bottom of the shell 1, which is conducive to the centralized collection of the waste water generated during cleaning. The support frame 16 is composed of a clamping ring at the top and a vertical rod at the bottom, which can lift the spray gun 15 in the shell 1 so that the spray gun 15 can be docked with the docking head 14 and the cover tube 18. One end of the cover tube 18 is not closed, and a clip is fixed on the inside, so that the cover tube 18 can cover the nozzle of the spray gun 15, so that the water flow entering the spray chamber can directly enter the cover tube 18 when it is sprayed from the nozzle, thereby reducing the splashing of the waste water sprayed from the nozzle on the inner wall of the shell 1, which is more conducive to the collection of waste water when cleaning the spray gun 15. The function of the guide pipe 19 is to enable the waste water in the cover tube 18 to flow vertically downward to the screen 10. The function of the waste water chamber 17 is to centrally collect the waste water generated during cleaning. The function of the waste water pipe 11 is to discharge the waste water in the waste water chamber 17 into the harmless treatment equipment.

[0025] Furthermore, a water pump 5 is fixedly installed on one side of the top of the shell 1, and a water pipe 6 is engaged with the output end of the water pump 5. The end of the water pipe 6 is engaged with the cross pipe 12. The function of the water pipe 6 is to pass the cleaning liquid in the mixing box 2 into the cross pipe 12, so that the nozzle 20 at the bottom end of the cross pipe 12 can spray out the cleaning liquid.

[0026] Furthermore, the output end of the water pump 5 is provided with a mixing box 2, and the top of the mixing box 2 is movably connected to a solvent cartridge 3. The function of the mixing box 2 is to facilitate the operator to add the cleaning solvent before cleaning and to facilitate the dilution of the solvent, thereby improving the cleaning effect of the equipment on the residual flux in the spray gun 15.

[0027] Furthermore, a water inlet pipe 4 is passed through one side wall of the mixing box 2 , and the water inlet pipe 4 is communicated with the interior of the water pump 5 through the mixing box 2 . The function of the water inlet pipe 4 is to introduce a flushing aqueous solution into the mixing box 2 , thereby flushing the spray gun 15 .

[0028] Furthermore, a transparent plate 8 is engaged on one side of the top of the movable plate 9, and the transparent plate 8 is movably connected to the outer shell 1. The transparent plate 8 can be engaged with the opening on the front of the outer shell 1, so that the opening is in a closed state when the equipment is running, thereby reducing the splashing of droplets out of the equipment during cleaning, and at the same time making it easier for the operator to observe the cleaning status of the spray gun 15 in the equipment.

[0029] Furthermore, electric push rods 7 are fixedly installed in the middle of both side walls of the shell 1, and the output ends of the two electric push rods 7 are respectively engaged with the docking joint 14 and the cover tube 18. The function of the electric push rods 7 is to flexibly adjust the positions of the docking joint 14 and the cover tube 18, thereby reducing the interference caused by placing the spray gun 15 into the equipment.

[0030] Furthermore, the docking joint 14 and the cover tube 18 are movably connected to the gun tail and the nozzle of the spray gun 15 through the electric push rod 7 respectively. When the spray gun 15 is placed in the shell 1, the docking joint 14 and the cover tube 18 can be smoothly docked with the spray gun 15, and at the same time, the spray gun 15 maintains better stability during flushing, which is more conducive to flushing the spray gun 15 clean.

[0031] The method of use of this embodiment is as follows: before using the spray gun 15 to clean the equipment in the flux spraying production line, it is necessary to first connect the equipment to an external power supply, then pull out the movable plate 9 from the opening on the front of the shell 1, place the spray gun 15 on the top of the support frame 16, and then push the movable plate 9 in. At this time, the transparent plate 8 closes the opening on the front of the shell 1, and then put the solvent to be used into the mixing box 2 through the solvent cylinder 3, and then start the electric push rods 7 on both sides of the shell 1, so that the docking joint 14 and the cover cylinder 18 are docked with the gun tail and the nozzle of the spray gun 15 respectively, and then start the water pump 5 so that the water pump 5 pumps clean water for flushing into the mixing box 2 and forms a cleaning solution with the solvent in the mixing box 2. The liquid is then sent into the water delivery pipe 6 by the water pump 5, and then enters the horizontal pipe 12. At this time, part of the cleaning solution will be sprayed from the nozzle 20 at the bottom end of the horizontal pipe 12 to the outer surface of the spray gun 15 to clean the outer surface of the spray gun 15, and the remaining cleaning solution will enter the interior of the spray gun 15 through the hose 13 and the docking joint 14, and then be sprayed out from the nozzle of the spray gun 15. The waste water sprayed from the nozzle will then be intercepted by the cover tube 18 and flow along the guide pipe 19 at the bottom end of the cover tube 18 to the wire mesh 10, and pass through the wire mesh 10 at the same time as the waste water flowing down from the outer surface of the spray gun 15, and then enter the wastewater chamber 17 to be collected centrally. Finally, the collected waste water will be sent to the subsequent harmless treatment equipment through the drain pipe.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
