Description

Technical Field

[0001] This utility model relates to the technical field of nozzle structures, specifically to a multi-directional spray nozzle structure. Background Technology

[0002] The flux spraying process for air conditioner condenser and radiator cores is a surface treatment technique used for subsequent furnace welding. Before brazing, the condenser needs to be pretreated by spraying flux onto the workpiece surface to ensure that each workpiece surface is covered with flux. During the flux spraying process, to ensure that both the surface and interior of the workpiece are coated with flux, the workpiece needs to be sprayed from different directions.

[0003] Chinese utility model patent CN214813125U discloses a cleaning line brazing system, including a workbench with a conveyor network and a brazing assembly connected to it. The brazing assembly spans the conveyor network and includes a nozzle, a spray pipe, a crossbeam, side plates, a storage bin, and a spray frame. The storage bin is mounted on the top surface of the spray frame. Vertical side plates are fixed to both sides of the spray frame, and a crossbeam is placed between the side plates. A spray pipe runs through the crossbeam, with one end of the spray pipe connected to the storage bin. In this cleaning line brazing system, during the spraying process, the spraying drives the sealing plate and rotating shaft to rotate, converting the spray flow rate into the rotation speed of the shaft. A speed sensor converts the detected shaft rotation speed signal into a digital signal displayed on the control screen, thus obtaining optimal flow data based on the product after brazing. This system is easy for beginners to use, includes an instrument to record the brazing flow rate for monitoring the brazing status, and has the function of recording and saving optimal brazing parameters, making it simple to learn. The current brushing system in this cleaning line can only brush the workpiece from the top and bottom. When the workpieces to be brushed have significant size differences, it cannot be adjusted according to the workpiece size, which can easily lead to insufficient flux being applied to certain parts of the workpiece surface, affecting the brushing effect. The existing nozzle structure has the technical problem of poor brushing effect when brushing workpieces of different sizes. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a multi-directional spray nozzle structure, which includes an inlet pipe and two side pipes. This multi-directional spray nozzle structure has the advantage of better spraying effect.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A multi-directional spray nozzle structure includes an inlet pipe and two side pipes. The side pipes are connected to the inlet pipe and are connected to an adjustable spray nozzle assembly. The adjustable spray nozzle assembly includes a fixed frame, an adjusting plate, an adjusting pipe, a flexible connecting pipe, and a side spray nozzle. One end of the adjusting plate is rotatably connected to the fixed frame. The adjusting pipe is fixedly mounted on the adjusting plate.

The side spray nozzle is connected to the adjusting pipe and is equipped with a side nozzle. An adjusting mechanism is provided between the fixed frame and the adjusting plate. A spray nozzle space is provided between the two adjustable spray nozzle assemblies, and the side spray nozzle faces the spray nozzle space.

[0007] By adjusting the tilt angle of the adjusting plate and adjusting pipe on the fixed frame through the adjustment mechanism, the height of the side spray pipe and side nozzle on the adjusting plate is adjusted, so that the side nozzle can be used for workpieces of different heights. This ensures that the surface of workpieces of different heights is fully and evenly coated with flux, avoiding the situation where some parts of the workpiece surface are not adequately coated with flux, thus achieving the advantage of better flux coverage.

[0008] Preferably, the adjustment mechanism includes a screw, a locking block, and an adjusting nut. The screw passes through the fixed frame, the locking block is fixedly connected to the screw, the locking block has an upward-facing slot for the adjustment plate to be inserted, and the adjusting nut is threadedly connected to the screw and engaged with the fixed frame.

[0009] This setup enables the adjustment mechanism to rotate the adjustment plate.

[0010] Preferably, the screw is threaded with a locking nut, which abuts against the adjusting nut.

[0011] This design prevents the adjusting nut from loosening and turning accidentally.

[0012] Preferably, the adjustment plate is arranged vertically.

[0013] This design allows for easy support of the adjustment plate via the card slot.

[0020] Preferably, it also includes a bottom branch pipe connected to the inlet pipe, the bottom branch pipe being connected to a bottom flow branch pipe, the bottom flow branch pipe being connected to a plurality of bottom nozzles, the bottom nozzles being equipped with bottom nozzles with upward openings, and bottom valves being installed between the top nozzles and bottom nozzles in the spraying space.

[0021] By setting it up this way, the bottom nozzle that cannot spray flux onto the workpiece is turned off, thus improving utilization efficiency.

[0022] Preferably, the regulating pipe is connected to at least two side nozzles, which are arranged along the axial direction of the regulating pipe.

[0023] With this setup, the workpiece can be brazed at different heights using two side nozzles, ensuring that the surface of different parts of the workpiece is fully covered and improving the brazing coverage effect.

[0024] Preferably, the side pipe is equipped with a side valve.

[0026] Compared with the prior art, this utility model has achieved beneficial technical effects:

[0027] 1. By adjusting the tilt angle of the adjusting plate and adjusting pipe on the fixed frame through the adjusting mechanism, the height of the side spray pipe and side nozzle on the adjusting plate is adjusted, so that the side nozzle can be used for workpieces of different heights. This ensures that the surface of workpieces of different heights is fully and evenly sprayed when performing brazing on workpieces of different heights, avoiding the situation where some parts of the workpiece surface are not fully covered, thus achieving the advantage of better coverage.

[0028] 2. A roller conveyor is installed in the soldering space to transport the workpiece.

[0033] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.

[0034] refer to Figure 1 and Figure 2 A multi-directional spray nozzle structure includes an inlet pipe 11, a top branch pipe 13, a bottom branch pipe 14, and two side branch pipes 12, all of which are connected to the inlet pipe 11.

[0035] The side pipe 12 is connected to an adjustable spraying assembly, which includes a fixed frame 21, an adjusting plate 22, an adjusting pipe 28, a flexible connecting pipe 23, and a side spray pipe 24. One end of the adjusting plate 22 is rotatably connected to the fixed frame 21. The adjusting pipe 28 is fixedly installed on the adjusting plate 22. Both ends of the flexible connecting pipe 23 are connected to the adjusting pipe 28 and the side pipe 12, respectively. The side spray pipe 24 is connected to the adjusting pipe 28 and is equipped with a side nozzle 25. A spraying space 15 is provided between the two adjustable spraying assemblies, and the side spray pipe 24 faces the spraying space 15. The side pipe 12 is equipped with a side valve 29. The adjusting plate 22 can be vertically flipped on the fixed frame 21, so that when the adjusting plate 22 rotates on the fixed frame 21, it can drive the side spray pipe 24 and the side nozzle 25 to adjust their height. The liquid inlet pipe 11 and the fixed frame 21 are fixed by a bracket, and the liquid inlet pipe 11 and the fixed frame 21 are fixed to the ground.

[0036] An adjustment mechanism is provided between the fixed frame 21 and the adjusting plate 22. The adjustment mechanism includes a screw 31, a locking block 32, and an adjusting nut 34. The screw 31 passes through the fixed frame 21, and the locking block 32 is fixedly connected to the screw 31. The locking block 32 has an upward-facing slot 33 for the adjusting plate 22 to be engaged. The adjusting nut 34 is threadedly connected to the screw 31 and engages with the fixed frame 21. The locking block 32 engages with the adjusting plate 22. A locking nut 35 is threadedly connected to the screw 31, and the locking nut 35 abuts against the adjusting nut 34. The adjusting plate 22 is vertically oriented. A support plate 26 is fixedly connected to the adjusting plate 22, and the support plate 26 engages with the side nozzle 24. The support plate 26 has a limiting groove 27 for the side nozzle 24 to be engaged.

[0037] The top branch pipe 13 is connected to a top flow branch pipe 41, which in turn is connected to multiple top nozzles 42. Each top nozzle 42 is equipped with a downward-opening top nozzle 43 and a top valve 44. The bottom branch pipe 14 is connected to a bottom flow branch pipe 51, which in turn is connected to multiple bottom nozzles 52. Each bottom nozzle 52 is equipped with an upward-opening bottom nozzle 53 and a bottom valve 54. The spray nozzle space 15 is located between the top nozzles 43 and the bottom nozzles 53. The regulating pipe 28 is connected to at least two side nozzles 24, which are arranged axially along the regulating pipe 28.

[0038] This embodiment has the following advantages:

[0039] By adjusting the tilt angle of the adjusting plate 22 and the adjusting pipe 28 on the fixed frame 21, the height of the side spray pipe 24 and the side nozzle 25 on the adjusting plate 22 is adjusted, so that the side nozzle 25 can be used for workpieces of different heights. When performing brazing on workpieces of different heights, it can ensure that the surface of the workpieces of different heights is fully and evenly brazed, avoiding the situation where some surfaces of the workpieces are not fully brazed, thus achieving the advantage of better brazing effect.

[0040] A roller conveyor is installed in the soldering space 15 to transport the workpiece to the soldering space 15. A pump is used to feed flux into the inlet pipe 11, which then delivers the flux into the side pipe 12, top pipe 13, and bottom pipe 14. The flux in the top pipe 13 is sprayed onto the upper surface of the workpiece from the top through the top spray pipe 42 and top nozzle 43; the flux in the bottom pipe 14 is sprayed onto the lower surface of the workpiece through the bottom spray pipe 52 and bottom nozzle 53; and the flux in the side pipe 12 is sprayed onto the side wall of the workpiece through the flexible connecting pipe 23, adjusting pipe 28, side spray pipe 24, and side nozzle 25. This allows flux to be sprayed onto the workpiece surface from multiple directions, ensuring thorough soldering and improving the soldering effect.

[0041] Rotating the adjusting nut 34 drives the screw 31, which is threaded to it, to move vertically. The screw 31's electric locking block 32 moves vertically. By adjusting the height of the locking block 32, the adjusting plate 22 is rotated on the fixed frame 21, thus realizing the function of rotating the adjusting plate 22 through the adjusting mechanism.

[0042] Tighten the locking nut 35 so that it presses against the adjusting nut 34. The friction between the locking nut 35 and the adjusting nut 34 prevents the adjusting nut 34 from rotating, thus preventing it from loosening and rotating accidentally.

[0043] The vertically positioned adjustment plate 22 is easier to insert into the slot 33, making it convenient to support the adjustment plate 22 through the slot 33.

[0044] The support plate 26 provides support to the side nozzle 24, thereby improving the stability of the side nozzle 24.

[0045] The inner wall of the limiting groove 27 provides support to the side nozzle 24, further improving the stability of the side nozzle 24.

[0046] By controlling the opening and closing of different top nozzles 42 through valves, when the workpiece size is small and the flux sprayed from some top nozzles cannot reach the workpiece, the top nozzles 42 that cannot spray flux onto the workpiece are closed, thereby avoiding the waste of flux and improving the utilization efficiency of flux.

[0047] By controlling the opening and closing of different bottom nozzles 52 through valves, when the workpiece size is small and the flux sprayed from some bottom nozzles cannot reach the workpiece, the bottom nozzles 52 that cannot spray flux onto the workpiece are closed, thereby avoiding flux waste and improving flux utilization efficiency.

[0048] When the adjusting pipe 28 is flipped along with the adjusting plate 22, the two side nozzles 24 are staggered in the vertical direction, so that the two side nozzles 24 are at different heights. This allows the workpiece to be sprayed and brazed at different heights through the two side nozzles 24, ensuring that the surface of different positions of the workpiece can be fully sprayed and brazed, thus improving the spraying and brazing effect.

[0049] When it is not necessary to spray flux from the side, closing the side valve 29 will prevent flux from flowing into the side nozzle 24, making it convenient to use.

[0050] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the utility model.
