Description

Technical Field

[0001] This invention relates to the field of sheet metal spraying technology, specifically to a rotary uniform spraying device for aluminum panel curtain wall processing. Background Technology

[0002] In the process of spraying curtain wall panels, existing technologies usually achieve the spraying effect by hand-held spraying, single-point large-area spraying, and up-and-down reciprocating spraying. However, these methods all have the problem of uneven spraying. In the end, some parts of the sprayed product are over-sprayed and raised, while other areas are under-sprayed and thin. All of these will affect the subsequent use.

[0003] Currently, the most common spraying process on the market is a reciprocating up-and-down spraying process. However, the equipment supplying the paint is stationary. This causes uneven air pressure during the reciprocating motion of the nozzle in the pipeline. For example, if the nozzle is higher than the paint outlet of the output device, the air pressure will be insufficient, resulting in a smaller spray volume. Conversely, if the nozzle is lower than the paint outlet of the output device, the air pressure will be excessive, resulting in a larger spray volume. These factors all affect the final spraying effect. Although existing technology has adopted differential pressure compensators, in actual application environments, due to pipeline structure, materials, wear, and slight deformation caused by compression, the final spray volume will still fluctuate slightly.

[0004] Furthermore, the coatings used in the spraying process of aluminum curtain wall panels often have a certain degree of adsorption. During or after spraying, the droplets generated to ensure atomization are easily adsorbed at the edges of the nozzle, resulting in stringing or scaling. Over time, this can easily lead to blockage. The spraying range may also change during the spraying process. Usually, staff are arranged to perform regular maintenance and inspections to ensure spraying efficiency. This method is rather cumbersome, and unexpected structural situations cannot be predicted in advance, which also brings certain economic losses to the operation. Summary of the Invention

[0005] The purpose of this invention is to provide a rotary uniform spraying device for aluminum panel curtain wall processing. This device aims to solve the problems in the prior art, such as uneven spraying on the aluminum panel of the curtain wall due to different air pressures during the spraying process at different heights, and reduced spraying efficiency due to scaling and clogging of droplets on the nozzle surface, which leads to aiming errors in the later spraying process.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rotary uniform spraying device for aluminum panel curtain wall processing includes a spraying component, which includes an output component and a conveying pipe connected to the output component; an atomizing component connected to the other end of the conveying pipe; the atomizing component includes a pressure relief shell and a connecting pipe; the pressure relief shell is internally provided with a guide pipe and a pressure relief pipe, the guide pipe and the pressure relief pipe are slidably connected, and an elastic element is fixedly provided inside the pressure relief pipe; the guide pipe squeezes the elastic element to form pressure relief; several sets of first guide grooves are opened on the circumferential sidewall of the guide pipe, and fluid is discharged along the ends of the several sets of first guide grooves; and a lifting component carries the displacement of the connecting pipe.

[0008] Preferably, the guide pipe is slidably connected to the inner wall of the pressure relief shell, and the guide pipe abuts against the pressure relief shell by setting a baffle to keep the discharge flow of the first guide channel constant.

[0009] Preferably, the sidewall of the pressure relief shell is provided with a plurality of diversion holes, the connecting pipe is provided with a first discharge hole on the side near the pressure relief pipe, and the first guide groove is connected to the diversion hole by a pipe, and the end of the first discharge hole extends to the end of the connecting pipe.

[0010] Preferably, when the guide pipe and the pressure relief pipe slide to abutment, the baffle on one side of the first guide groove does not slide to coincide with the horizontal projection of the diversion hole.

[0011] Preferably, the pressure relief pipe and the pressure relief shell are fixedly connected by several sets of rods, and a second flow guide groove is formed between the rods. The side of the pressure relief shell near the pressure relief pipe forms a flow gathering cavity with the pressure relief shell. A second discharge hole is opened at the top of the flow gathering cavity. After the end of the first flow guide groove extends to the flow gathering cavity, it is discharged from the second discharge hole.

[0012] Preferably, the end of the first discharge hole extends to the outlet side of the second discharge hole, the connecting pipe is arc-shaped on the circumferential sidewall of the first discharge hole, and when it extends outward, it diffuses circumferentially. The second discharge hole rotates in the opposite direction to the first discharge hole, and the flow rates of the second discharge hole and the first discharge hole are different.

[0013] Preferably, a rotating platform is provided on the side of the guide pipe near the pressure relief pipe, and a rotating rod is provided on the axis of the rotating platform. The rotating rod extends through the pressure relief pipe and the pressure relief shell to the outlet of the first discharge hole. One end of the rotating rod is limited inside the rotating platform, and the other end is provided with a centrifugal element.

[0014] Preferably, the centrifugal component is fixedly connected to the rotating rod, and the surface of the centrifugal component is provided with several sets of blades.

[0015] Preferably, the rotating rod is hinged to a plurality of push rods on its circumferential sidewall, and a cleaning component is provided at the other end of the push rod.

[0016] Preferably, the push rod and the rotating rod are hinged by a torsion spring. When the cleaning component is attached to the end face of the pressure relief shell, its horizontal projection direction does not coincide with either the second discharge hole or the first discharge hole. When the elastic component fully releases its elastic potential energy, the cleaning component reaches the outer end of the arc surface where the outlet of the first discharge hole is located, without disengaging from the arc surface.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The coating material is output from the spraying equipment along the conveying pipe to the connecting pipe, and then first enters the guide pipe, simultaneously squeezing the elastic element to create pressure relief. At the same time, all the fluid is discharged along the first guide channel to the diversion hole and the second guide channel respectively. The fluid is distributed in two parts and discharged from the second discharge hole and the first discharge hole. At the outlets of the second and first discharge holes, the two sets of fluids rotate and collide in opposite directions, thereby generating finer droplets. Due to the different flow rates of the second and first discharge holes, the airflow can drive the centrifugal element to rotate. While the centrifugal element rotates, further collisions refine the droplets. The cleaning component retracts to the plane of the second discharge hole under the action of the torsion spring, without blocking the second and first discharge holes. When the output component stops the extraction operation, the elastic component releases its elastic force to reset the guide tube, and simultaneously drives the rotating rod to retract. At this time, the cleaning component can squeeze the plane of the second discharge hole and spread outwards to the arc surface of the first discharge hole due to the hinge. The instantaneous acceleration pushes the residual droplets adsorbed on the arc surface of the first discharge hole to the outside, which can ensure that the spraying process can be stopped multiple times until the nozzle is aligned with the aluminum plate before spraying. This saves a lot of costs and can quickly and efficiently clean sticky paint droplets in a short time. Attached Figure Description

[0028] To ensure a clear and complete description of the technical solutions in the embodiments of the present invention, and to make the features and advantages more apparent and understandable, the specific implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figures 1 to 7 This invention provides a rotary uniform spraying device for aluminum panel curtain wall processing, including a spraying component 1, which includes an output component and a delivery pipe 11 connected to the output component. In this design, the output component is a paint delivery pump. For the paint delivery pump, a pneumatic diaphragm pump, such as DDP-90E or Triton 308, can be selected for high viscosity or explosion-proof applications. For in-tank extraction / high flow rate applications, a pneumatic plunger pump, such as the FY or BSY series, can be selected. No specific limitation is made here. The delivery pipe 11 is a flexible hose structure, which allows for bending without folding during bending. Figure 2 and Figure 3 As shown, the existing equipment has a circular diameter hose that folds during the up-and-down movement of the lifting equipment. Because the lifting equipment is frequently raised and lowered during the spraying process, it is prone to folding and wear over a long period of time, and the bending process can also affect the fluid pressure inside the pipe.

[0031] The atomizing component 2 is connected to the other end of the delivery pipe 11. The atomizing component 2 includes a pressure relief shell 21 and a connecting pipe 22. Both the connecting pipe 22 and the pressure relief shell 21 can be made of stainless steel; the specific material is not limited here. The pressure relief shell 21 internally includes a guide pipe 211 and a pressure relief pipe 212. The guide pipe 211 and the pressure relief pipe 212 are also made of stainless steel and need to ensure that their surfaces are smooth and do not easily adsorb droplets. The guide pipe 211 and the pressure relief pipe 212 are slidably connected to ensure that they fit together. A sealing ring can be used between them to achieve a tight seal. The sealing effect is achieved, and an elastic element 2121 is fixedly installed inside the pressure relief pipe 212. The elastic element 2121 can be a spring or other elastic medium, which is not specifically limited here. The flow guide pipe 211 compresses the elastic element 2121 to form pressure relief. Several sets of first flow guide grooves 2111 are opened on the circumferential sidewall of the flow guide pipe 211. The fluid is discharged along the ends of the several sets of first flow guide grooves 2111. In this scheme, when the fluid enters the flow guide pipe 211, it first impacts and contacts the front end of the flow guide pipe 211 located on the same horizontal plane as the first flow guide grooves 2111 and in the flow direction. On the surface, and after the collision, the guide tube 211 is displaced and the elastic element 2121 is compressed. During this process, it is important to note that the end face of the guide tube 211 should be inclined to ensure that the fluid can be guided along the inclined surface to the outlet after squeezing the guide tube 211. Secondly, it is important to note that during this process, the elastic extension range of the elastic element 2121 should be able to withstand the maximum pressure provided by the output component within the delivery pipe 11. Similarly, when the output component provides the minimum pressure required to complete the work, it will also squeeze the elastic element 2121, causing the elastic element 2121 to deform. This ensures that the elastic element 2121 can act as a buffer to balance the pressure inside the pipe at all times, whether facing maximum or minimum pressure. The lifting element 3 carries the connecting pipe 22 to move. The lifting element 3 can be driven by a servo motor with a sleeve and a lead screw, or it can be driven by a conventional track and a motor to move up and down or left and right. It can be determined according to the actual needs of the scenario to ensure that the lifting element 3 drives the connecting pipe 22 to move, thereby achieving the reciprocating spraying process of the aluminum panel curtain wall. The specific lifting equipment is not specifically limited here.

[0032] It is important to note that for different aluminum panels, the emergency stop and start of the output component should be controlled. When the connecting pipe 22 has moved to the end of the aluminum panel curtain wall to be sprayed, the output component should be opened to start operation. During continuous spraying, when the connecting pipe 22 has moved to the other end of the aluminum panel curtain wall, the output component can be stopped by emergency stop. As mentioned above, the lifting component 3 uses a sleeve and lead screw combined with a servo motor for drive displacement, as well as some conventional lifting equipment, it is necessary to ensure the maximum limit of the motion trajectory during the lifting process. Similarly, the maximum limit of the motion trajectory also represents the maximum range of motion. When spraying aluminum panel curtain walls, the movement trajectory is often set to exceed the maximum size of the aluminum panel that can be sprayed. However, when dealing with some small aluminum panels, the output component continues to output even when the connecting pipe 22 exceeds the spraying range that the aluminum panel curtain wall can accept. This leads to a large amount of paint waste. Therefore, this problem can be avoided by setting an emergency stop and start conveying method. During the process of the output component extracting paint and conveying it along the connecting pipe 22, the state of the conveying pipe 11 is as shown in the figure. There will be no sticking or folding. Therefore, while ensuring the normal output pressure of the equipment, the service life of the conveying pipe 11 can also be extended.

[0033] Furthermore, the guide pipe 211 is slidably connected to the inner wall of the pressure relief shell 21, and the guide pipe 211 abuts against the pressure relief shell 21 through a baffle 2112. The baffle 2112 and the pressure relief shell 21 can also be sealed by a sealing ring to ensure that the liquid discharged from the first guide channel 2111 will not flow back into the gap generated by the relative movement between the pressure relief shell 21 and the guide pipe 211. At the same time, the discharge flow rate of the first guide channel 2111 remains constant, so that when the coating impacts the guide pipe 211, it can only relieve pressure without limiting the flow.

[0034] In practical use, the lifting component 3 can be opened first, and the lifting component 3 carries the connecting pipe 22 up and down. During this process, the connecting pipe 22 can spray the aluminum panel curtain wall during the raising and lowering process. During the raising and lowering process, the conveying pipe 11 will not bend or fold at a large angle, thereby reducing the pressure change inside the conveying pipe 11. When the height of the connecting pipe 22 is higher or lower than the height of the output component, even with the presence of a pressure difference compensation device, the pressure will still change. At this time, the pressure output by the output component will be impacted to the squeezing guide pipe 211, which will squeeze the elastic component 2121, thereby achieving the effect of pressure relief. During the process of the paint being squeezed against the elastic component 2121, the elastic potential energy of the elastic component 2121 will be... The pressure is adjusted quickly and without delay based on the actual contact pressure. After the adjustment is balanced, the coating is discharged from the first guide channel 2111. This allows for real-time adjustment based on the pressure transmitted from the conveying pipe 11 to the connecting pipe 22. Discharge after adjustment achieves a uniform spraying effect. During the spraying process, when the conveying pipe 11 is empty, the paint is drawn from the conveying pipe 11 and sprayed out. At the moment when the paint impacts the conveying pipe 11 and is directly discharged, that is, when it comes into contact with the end of the aluminum panel curtain wall, the spraying may be heavier. This results in the final sprayed aluminum panel curtain wall being thicker at both ends and thinner in the middle. The use of elastic element 2121 to release pressure before discharge can avoid this problem, thus making the spraying process smoother.

[0035] Example 2

[0036] Please see Figures 1 to 7 This invention provides a rotary uniform spraying device for aluminum panel curtain wall processing. The pressure relief shell 21 has several diversion holes 213 on its side wall. The connecting pipe 22 has a first discharge hole 221 on the side near the pressure relief pipe 212. The first guide groove 2111 is connected to the diversion hole 213 through a pipe. The end of the first discharge hole 221 extends to the end of the connecting pipe 22. This allows a portion of the fluid to be transported to the diversion hole 213 through the first guide groove 2111 after the coating comes into contact with the guide pipe 211. The fluid is then discharged into the first discharge hole 221 through the pipe and finally discharged from the first discharge hole 221.

[0037] Furthermore, when the guide pipe 211 and the pressure relief pipe 212 slide to contact, the baffle 2112 on one side of the first guide groove 2111 does not slide to overlap with the horizontal projection of the diversion hole 213, ensuring that there is no overlap with the diversion hole 213 within the movement trajectory of the baffle 2112, which would cause blockage.

[0038] Furthermore, the pressure relief pipe 212 and the pressure relief shell 21 are fixedly connected by several sets of rods, and a second flow guide groove 2122 is formed between the rods. A portion of the fluid discharged from the first flow guide groove 2111 flows along the pipe wall of the pressure relief shell 21 to the second flow guide groove 2122. The side of the pressure relief shell 21 near the pressure relief pipe 212 forms a flow convergence cavity 2123 with the pressure relief shell 21. The fluid after passing through the second flow guide groove 2122 enters the flow convergence cavity 2123, such as... Figure 4 and 5 As shown, the flow-gathering cavity 2123 is truncated cone-shaped, and the fluid in the flow-gathering cavity 2123 tends to accumulate. The pressure relief shell 21 has a second discharge hole 2124 at the top of the flow-gathering cavity 2123. After the end of the first guide groove 2111 extends to the flow-gathering cavity 2123, it is discharged from the second discharge hole 2124. The fluid in the flow-gathering cavity 2123 accumulates and is then discharged along the second discharge hole 2124.

[0039] Furthermore, the end of the first discharge hole 221 extends to the outlet side of the second discharge hole 2124. The connecting pipe 22 is arc-shaped on the circumferential sidewall where the first discharge hole 221 is located, and it spreads outward in circumferential direction at the same time. The specific arc-shaped surface can be set according to actual needs to ensure the spraying range.

[0040] The second discharge hole 2124 rotates in the opposite direction to the first discharge hole 221, causing the two sets of coatings to collide and form atomization during the collision. It is also necessary to ensure that the flow rates of the second discharge hole 2124 and the first discharge hole 221 are different.

[0041] The rest of the structure is the same as in Example 1.

[0042] In actual use, when the paint fluid enters the guide pipe 211, it is depressurized after colliding with the compression elastic element 2121 of the guide pipe 211. After depressurization, part of the fluid is discharged through the first guide groove 2111 and enters the pipe through the diversion hole 213, and reaches the first discharge hole 221 along the pipe, and is discharged from the end of the first discharge hole 221. At the same time, another part of the paint fluid is discharged along the first guide groove 2111 and then along the pipe wall of the pressure relief shell 21 through the second guide groove 2122 to reach the flow gathering cavity 2123. After gathering in the flow gathering cavity 2123, it is discharged from the second discharge hole 2124. At this time, the airflows discharged from the ends of the first discharge hole 221 and the second discharge hole 2124 rotate in opposite directions, so as... Figure 5 A collision occurs at point a, thus achieving the effect of collision atomization.

[0043] Example 3

[0044] Please see Figures 1 to 7A rotary uniform spraying device for aluminum panel curtain wall processing is provided, including a guide pipe 211 with a rotating table 24 near the pressure relief pipe 212. A rotating rod 241 is provided on the axis of the rotating table 24. The rotating rod 241 passes through the pressure relief pipe 212 and the pressure relief shell 21 and extends to the outlet of the first discharge hole 221. The rotating table 24 can be integrally formed with the pressure relief pipe 212, and both the rotating table 241 and the rotating rod 241 are made of stainless steel. One end of the rotating rod 241 is limited inside the rotating table 24 and is rotatably connected to the rotating table 24 in the circumferential direction without disengaging. The other end is provided with a centrifugal element 242, which is fixedly connected to the rotating rod 241. The centrifugal element 242 has several sets of blades on its surface.

[0045] It should be noted that the blades of the centrifugal element 242 should be arranged in multiple sets and at an angle to ensure that the gas discharged from both the first discharge port 221 and the second discharge port 2124 can drive the blades to rotate. Similarly, when the fluid directly collides with the centrifugal element 242 and is broken up, some fluid also directly contacts the blades of the centrifugal element 242. Subsequently, the centrifugal force of the blades produces a centrifugal atomization effect. That is, the fluid discharged from the first discharge port 221 first collides with the fluid discharged from the second discharge port 2124. After the collision, due to the interaction between the second discharge port 2124 and the first discharge port 2124, the fluid is further atomized. The different flow rates of the two fluids cause them to rotate in two directions after collision, with the one with the larger flow rate remaining. The fluid then rotates by colliding with the blades of the centrifugal element 242. During the rotation of the centrifugal element 242, some fluid adsorbed onto the surface of the blades is thrown out by the centrifugal element 242, achieving a centrifugal atomization effect. The thrown-out droplets will collide with the fluid that is about to be drawn in and discharged from the first discharge hole 221 and the second discharge hole 2124, achieving a repeated atomization effect. Finally, the fluid after passing through the centrifugal element 242 can be sprayed onto the surface of the aluminum panel curtain wall with a more uniform droplet effect.

[0046] The rest of the structure is the same as in Example 2.

[0047] Example 4

[0048] Please see Figures 1 to 9This invention provides a rotary uniform spraying device for aluminum panel curtain wall processing, comprising a rotating rod 241 with several sets of push rods 243 hinged to the circumferential side wall, and a cleaning component 244 at the other end of the push rod 243. The cleaning component 244 should be made of plastic material and should always be in contact with the end face where the second discharge hole 2124 and the first discharge hole 221 are located. The push rod 243 and the rotating rod 241 are hinged by a torsion spring. When the push rod 243 is subjected to force limit, it can still maintain the tendency to displace in the direction of the push rod 243 axis. The push rod 243 should be relatively narrow, similar to the blades on the centrifugal component 242, to avoid a wide and large range of obstruction of the fluid movement trajectory. The dimensions of the push rod 243 and the blades are not specifically limited here.

[0049] Furthermore, when the cleaning component 244 is attached to the end face of the pressure relief shell 21, its horizontal projection direction does not coincide with either the second discharge hole 2124 or the first discharge hole 221, thus avoiding blockage of the first discharge hole 221 and the second discharge hole 2124. It should be noted that the height of the first discharge hole 221 should be greater than the height of the second discharge hole 2124, which is greater than the horizontal height of the cleaning component 242. This ensures that when the cleaning component 242 is attached to the plane where the second discharge hole 2124 is located, it will not block the first discharge hole 221 during the rotation process with the rotating rod 241. 1. Similarly, the torsion spring should ensure that the centrifugal force generated during the rotation of the rotating rod 241 will not disengage the cleaning component 242 from the plane where the second discharge hole 2124 is located. Similarly, the elastic force of the torsion spring is less than the elastic potential energy of the elastic component 2121. Only when the elastic component 2121 is reset can the cleaning component 242 be driven to overcome the elastic force of the torsion spring and slide along the arc surface where the first discharge hole 221 is located. When the elastic component 2121 completely releases its elastic potential energy, the cleaning component 244 reaches the outer end of the arc surface where the outlet of the first discharge hole 221 is located, and has not disengaged from the arc surface.

[0050] In actual use, when the fluid passes through the centrifugal component 242, the centrifugal component 242 rotates, which in turn drives the rotating rod 241 to rotate. When the rotating rod 241 rotates, the push rod 243 also drives the cleaning component 244 to rotate. When the output component stops conveying fluid, the rotating rod 241 will reset along with the guide pipe 211. During the retraction of the rotating rod 241, the cleaning component 244 comes into contact with the arc surface where the first discharge hole 221 is located and slides along the arc surface to clean. During the sudden stop of the output component, the elastic component 2121 will quickly reset, thereby quickly spreading the cleaning component 244 along the arc surface where the first discharge hole 221 is located and pushing away the paint droplets remaining on the arc surface. Since the lifting component 3 needs to spray multiple times during the spraying of an aluminum panel curtain wall, the arc surface where the first discharge hole 221 is located can be cleaned during each spraying process.

[0051] Furthermore, since the pressure inside the delivery pipe 11 changes as the position of the lifting component 3 rises and falls, the distance the rotating rod 241 extends after the fluid squeezes the guide pipe 211 also changes constantly. When the output pressure is high, the centrifugal component 242 at the end of the rotating rod 241 extends longer, thus reducing the power supplied to the centrifugal component 242. When the output pressure is low, the centrifugal component 242 at the end of the rotating rod 241 extends shorter, thus increasing the power supplied to the centrifugal component 242. The decrease and increase in power here are due to the power loss determined by the fluid movement path, but this is only for reference. The specific implementation plan needs to be based on the extension length of the centrifugal component 242 and the efficiency of the centrifugal component 242 in converting the fluid kinetic energy into rotation. The specific method is not limited here.

[0052] The remaining structure is the same as in Example 3.
