Detailed Implementation

[0031] Traditional sand-type coating methods mainly employ manual brushing or simple spraying equipment. However, manual brushing is inefficient, and current spraying equipment lacks the function of stirring and recycling the sprayed paint, leading to paint sedimentation, reduced spraying efficiency, and paint waste.

[0032] In view of this, this application provides a casting sand mold flow coating machine. The concept is to place the workpiece to be coated on the spraying platform, draw coating from the storage tank through a delivery pump, and spray the workpiece with a handheld nozzle through a delivery hose. At the same time, a mixer stirs the coating in the storage tank to prevent it from settling. Excess coating generated by spraying the workpiece on the spraying platform with the handheld nozzle is returned to the storage tank through a recycling channel for reuse, reducing waste. This solves the problems of slow coating efficiency and coating waste on the surface of sand molds caused by manual brushing and the use of spraying equipment lacking stirring and recycling functions in the prior art.

[0038] Example

[0039] This application provides a flow coating machine for casting sand molds, such as... Figures 1 to 4 As shown, the casting sand mold mobile coating machine includes a spraying platform 1, a mixer 3, a delivery pump 4, a delivery hose 5, and a handheld nozzle 6.

[0040] The spraying platform 1 is located on one side of the storage tank 2, and a recycling channel 7 is provided on the side of the platform closest to the storage tank 2. The recycling channel 7 is connected to the storage tank 2.

[0041] Specifically, the spraying platform 1 includes a support 8, a spraying working surface 9, and a side baffle 10. The spraying working surface 9 is welded to the top of the support 8, and its two ends are inclined inward to form paint collection channels 11. The side baffle 10 is arranged around the spraying working surface 9 and is vertically arranged. It has flow holes 12. The paint collection channels 11 are connected to the recycling channels 7 through the flow holes 12. Preferably, the spraying working surface 9 is inclined downward from the end away from the storage tank 2 to the end closer to the storage tank 2. The storage tank 2 includes at least two storage chambers 14, which are arranged sequentially from the end closer to the spraying platform 1 to the end away from the spraying platform 1. The recycling channels 7 include a first recycling channel 15 and a second recycling channel 16. The first recycling channel 15 is connected to the spraying platform 1, and the second recycling channel 16 is slidably sleeved on the end of the first recycling channel 15 away from the spraying platform 1.

[0042] The bracket 8 provides a support base for the workpiece placed on the spraying surface 9. The side baffle 10 holds the spraying paint, which splashes out of the spraying platform 1 during application. The two ends of the spraying surface 9 are inclined inwards, allowing the paint sprayed onto the surface to flow into the paint collection channel 11 along the inclined surface. Simultaneously, because the spraying surface 9 is inclined downwards from the end furthest from the storage tank 2 towards the end closer to the storage tank 2, the paint collected in the paint collection channel 11 flows into the recovery channel 7 through the flow hole 12. The first recovery channel 15 has a recovery chute on its outer side, which does not extend to the end. The second recovery channel 16 has a recovery slider on its inner side. The second recovery channel 16 connects the recovery chute and the... The recovery slider is slidably connected to the first recovery channel 15. It should be noted that the recovery channel 7 is also inclined downward from the end near the spraying platform 1 to the end away from the spraying platform 1, so that the paint on the recovery channel 7 can enter the storage tank 2 better. To prevent the second recovery channel 16 from sliding down automatically under the action of gravity, a number of adjustment holes are provided in the recovery chute. The second recovery channel 16 is provided with a positioning through hole. When the second recovery channel 16 slides to the corresponding position outside the first recovery channel 15, a positioning pin is inserted into the positioning through hole and one of the adjustment holes to fix the second recovery channel 16. By adjusting the length of the second recovery channel 16 sliding out of the first recovery channel 15, it is determined which storage chamber 14 the recovered paint in the recovery channel 7 enters.

[0043] The mixer 3 is mounted on the storage tank 2 and is used to stir the coating material in the storage tank 2.

[0044] Specifically, the mixer 3 is movably mounted on the storage tank 2 via a movable mounting assembly. The movable mounting assembly includes a sliding frame, a slider 21, and a mounting plate 22. The sliding frame includes a first sliding frame 23 and at least two second sliding frames 24. The second sliding frames 24 are connected to the storage tank 2, and each second sliding frame 24 is located on one side of a storage chamber 14. The first sliding frame 23 is connected to the end of each of the at least two second sliding frames 24 away from the storage tank 2. The first sliding frame 23 is provided with a first sliding groove 25, and the second sliding frame 24 is provided with a second sliding groove 26. The second sliding groove 26 communicates with the first sliding groove 25. The slider 21 is slidably disposed in the first sliding groove 25 or the second sliding groove 26. The mounting plate 22 is connected to the slider 21, and the mixer 3 is fixedly mounted on the mounting plate 22.

[0045] The slider 21 can slide within the first slide groove 25 and at least two second slide grooves 26, thereby adjusting the position of the mixer 3 so that it can be positioned above any of the storage chambers 14. To prevent the mixer 3 and the mounting plate 22 from pulling the slider 21 out of the first slide groove 25 or the second slide groove 26, causing the mixer 3 to fall, both the first slide groove 25 and the second slide groove 26 are T-shaped, and the first sliding frame 23 and the second sliding frame 24 are integrally formed structures.

[0046] The inlet of the conveying pump 4 is connected to the storage tank 2, and its outlet is connected to the conveying hose 5. The end of the conveying hose 5 away from the outlet of the conveying pump 4 is connected to the handheld nozzle 6, which is used for spraying paint.

[0047] Specifically, the conveying pump 4 is installed on one side of the storage tank 2 via the mounting bracket 17, and its inlet is connected to the main inlet pipe 18. The other end of the main inlet pipe 18 is connected to at least two inlet branch pipes 19. The other end of each inlet branch pipe 19 is connected to a storage chamber 14, and a valve 20 is provided on the inlet branch pipe 19.

[0048] The operator can choose to open different valves 20 to select the delivery pump 4 to deliver the corresponding paint from the storage chamber 14 to the handheld nozzle 6. It should be noted that, in order to prevent paint mixing, when changing the spray paint, it is necessary to let it run empty for one minute to clean the delivery pump 4, delivery hose 5 and handheld nozzle 6 of the previous paint residue, and at the same time clean the spraying surface 9. Waste liquid is collected at the end of the recycling channel 7 through the waste liquid bucket. Compared with the paint wasted by spraying for a long time without recycling, the paint wasted by letting it run empty for one minute is very small. Overall, it still reduces paint waste. The handheld nozzle 6 is a duckbill nozzle, which is made of seamless steel pipe.

[0049] In some embodiments, the side baffle 10 is provided with a plurality of lifting hooks 13. Specifically, the plurality of lifting hooks 13 are provided at the four corners of the side baffle 10, and the lifting hooks 13 facilitate the movement of the spraying platform 1.

[0050] In some embodiments, the movable mounting assembly further includes a stabilizing structure, which includes a first positioning hole 27, a second positioning hole 28, and a stabilizing pin 29. The first positioning hole 27 is formed on the second sliding frame 24 and passes through the second sliding groove 26. The second positioning hole 28 is formed on the slider 21. When stabilizing, the stabilizing pin 29 passes through the first positioning hole 27 and the second positioning hole 28 to fix the slider 21, the mounting plate 22, and the mixer 3.

[0051] In summary, the casting sand mold mobile coating machine provided in this application places the workpiece to be coated on the spraying platform, uses a delivery pump to draw coating from the storage tank, and sprays the workpiece through a delivery hose and a handheld nozzle. At the same time, a mixer stirs the coating in the storage tank to prevent it from settling. Excess coating generated by the handheld nozzle when spraying the workpiece on the spraying platform is returned to the storage tank through a recycling channel for reuse, reducing waste. This solves the problems of slow coating efficiency and coating waste on the sand mold surface caused by manual brushing and the use of spraying equipment lacking stirring and recycling functions in the prior art.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
