Description

Technical Field

[0001] This invention relates to the field of spray painting equipment technology, specifically a spray painting device for processing colored glass bricks. Background Technology

[0002] The production of colored glass bricks begins with precise raw material proportions. Quartz sand, soda ash, limestone, and metal oxide colorants are melted at high temperatures to form a uniform colored glass liquid. The glass liquid is then pressed into shape using molds or cast into shape, and then annealed in a precisely controlled annealing furnace to eliminate internal stress and ensure the stability of the brick structure. To meet special decorative or functional requirements, one side of the brick is sprayed with a high-performance epoxy primer and polyurethane topcoat, and then heated and cured in a tunnel furnace to form a durable coating with brilliant colors and strong adhesion, greatly expanding its possibilities for architectural and artistic applications.

[0003] There are two major drawbacks in the current technology for painting glass bricks: First, due to the smooth and inert nature of the glass surface, the traditional manual polishing process is rough and the cleaning is not thorough, resulting in insufficient paint adhesion and problems such as peeling and flaking, which seriously affect the durability of the finished product. Second, there is a lack of efficient automated masking methods, which makes it very easy to contaminate the sides and back of the glass bricks during the spraying process. This not only destroys the original light transmission and aesthetics of the glass bricks, but more importantly, the contaminated surface will greatly weaken the adhesion to the building mortar, creating a safety hazard for the stability of the wall after construction. Summary of the Invention

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] In one embodiment, see Figure 1A painting device for processing colored glass bricks includes a column 1, a rotating ring 5 on the outside of the column 1, the rotating ring 5 being rotatably connected to the column 1, a connecting plate 6 fixed on the side wall of the rotating ring 5, a support plate 7 fixed at the end of the connecting plate 6 away from the rotating ring 5, a shielding mechanism 2 on the top of the support plate 7 for shielding the side wall of the glass brick, wherein a first mounting plate 8, a second mounting plate 9, and a third mounting plate 10 are sequentially fixed on the side wall of the column 1 according to the rotation direction of the rotating ring 5, a grinding mechanism 3 is installed at the bottom of the first mounting plate 8 for grinding the top of the glass brick, a cleaning mechanism 4 is installed at the bottom of the second mounting plate 9 for cleaning the top of the ground glass brick, and a paint spray head 11 for spraying paint on the top of the glass brick is installed at the bottom of the third mounting plate 10.

[0029] In this embodiment, when the device is spraying paint on the glass bricks, the glass bricks are placed on top of the support plate 7, and the rotating ring 5 is driven to rotate by an external rotating device. The rotating ring 5 drives the support plate 7 to move in a circle around the column 1 through the connecting plate 6. When the support plate 7 rotates to a certain position, the shielding mechanism 2 on the top of the support plate 7 automatically shields the four sides of the glass bricks, which can effectively prevent the paint from contaminating the non-painted surfaces of the glass bricks during the subsequent painting process. On the one hand, it can ensure the light refraction effect of the glass bricks during subsequent use, and on the other hand, it can ensure the adhesion of the non-painted surfaces of the glass bricks to the mortar, thereby improving the stability of the wall. In addition, when the shielding mechanism 2 shields the non-painted surfaces of the glass bricks, it also... This mechanism acts as a positioning and clamping device for the glass brick, ensuring stability during the subsequent grinding of the top of the glass brick and the precision of the paint spraying head 11. After the masking mechanism 2 has masked the non-painted surfaces of the glass brick, the glass brick will pass under the first mounting plate 8, the second mounting plate 9, and the third mounting plate 10 in sequence as the rotating ring 5 continues to rotate. When the glass brick passes under the first mounting plate 8, the grinding mechanism 3 at the bottom of the first mounting plate 8 grinds the top of the glass brick, thereby damaging the smooth top of the glass brick and creating micro-roughness, which improves the adhesion of the subsequent paint and ensures the painting effect. When the glass brick passes under the bottom of the second mounting plate 9, the grinding mechanism 3 at the bottom of the second mounting plate 9 grinds the top of the glass brick, thereby damaging the smooth top of the glass brick and creating micro-roughness, which improves the adhesion of the subsequent paint and ensures the painting effect. The cleaning mechanism 4 cleans the top of the polished glass brick, thus preventing dust generated during polishing from adhering to the top of the glass brick and affecting subsequent painting, further ensuring the adhesion of the paint. When the glass brick passes under the third mounting plate 10, the top of the glass brick can be painted through the paint spray head 11 at the bottom of the third mounting plate 10. The paint spray head 11 can be connected to external painting equipment. After the glass brick is painted, as the rotating ring 5 continues to rotate, the shielding mechanism 2 automatically releases the shielding of the side wall of the glass brick, making it convenient for workers to remove the painted glass brick from the support plate 7. That is, the present invention can sequentially complete the shielding and polishing of the glass brick through the circumferential movement of the support plate 7. The process involves four key steps: cleaning, painting, and spraying. The shielding mechanism 2 wraps around the four sides of the glass brick, effectively preventing paint contamination. This maintains the original light transmission and refraction characteristics of the glass brick while ensuring the permanent adhesion strength between the non-painted surface and the building mortar. At the same time, this mechanism also provides a stable clamping for the brick, providing precise positioning for subsequent processing. The grinding mechanism 3 grinds the top of the glass brick, significantly enhancing coating adhesion through surface roughening treatment. The subsequent cleaning mechanism 4 thoroughly removes grinding dust, providing an ideal base surface for spraying. Finally, a dedicated spray head 11 completes the uniform spraying. This process fundamentally solves the core problem of weak adhesion of glass materials and the issue of paint easily contaminating the non-painted surface of the glass brick, significantly improving painting efficiency, adhesion, and finished product reliability.

[0030] Please see Figure 3The shielding mechanism 2 includes multiple shielding plates 23 arranged in a matrix above the support plate 7. Each shielding plate 23 is connected to a transmission component, which is used to drive the multiple shielding plates 23 to rotate synchronously, so that the shielding plates 23 are in contact with the side wall of the glass brick.

[0031] When spraying paint on glass bricks, the device places the glass bricks on top of the support plate 7 and drives the rotating ring 5 to rotate through an external rotating device. The rotating ring 5 drives the support plate 7 to make a circular motion around the column 1 through the connecting plate 6. When the support plate 7 rotates to a certain position, the transmission component drives multiple shielding plates 23 to flip upwards synchronously until the shielding plates 23 are in contact with the sides of the glass brick. At this time, the shielding plates 23 play a shielding role on the four sides of the glass brick, effectively avoiding the subsequent paint from contaminating the non-painted surfaces of the glass brick. In addition, the shielding plates 23 also play a positioning and clamping role for the glass brick during the flipping process, thereby ensuring the stability of the glass brick top grinding process and the accuracy of the paint spray head 11 spraying paint on the glass brick.

[0032] Please see Figure 3 , Figure 4 and Figure 5 The transmission assembly includes multiple support seats 211 fixedly connected to the top of the support plate 7 and arranged in a matrix. Each support seat 211 is rotatably connected to a transmission rod 213. The transmission rod 213 is fixedly connected to a rotating plate 24. Symmetrically distributed torsion springs 212 are fixed on the side wall of the rotating plate 24. The other end of the torsion spring 212 is fixedly connected to the inner wall of the support seat 211. The rotating plate 24 is connected to a baffle plate 23 through an adjustment component. The adjustment component is used to adjust the position of the baffle plate 23. The support plate 7 is connected to a pressing component. The pressing component is used to press the rotating plate 24, thereby causing the rotating plate 24 to drive the baffle plate 23 to rotate.

[0033] When the device is spraying paint on glass bricks, the rotating ring 5 drives the support plate 7 to rotate in a circle around the column 1 via the connecting plate 6. When the support plate 7 rotates to a certain position, the pressing component presses the rotating plate 24, causing the rotating plate 24 to rotate upward. As the rotating plate 24 rotates, the adjusting component drives the shielding plate 23 to shield the side wall of the glass brick, thereby preventing subsequent paint from contaminating the non-painted surfaces of the glass brick. After the glass brick is sprayed, as the rotating ring 5 continues to rotate, the pressing component stops pressing the rotating plate 24, and the rotating plate 24, under the action of the torsion spring 212, drives the shielding plate. 23 is reset, thereby removing the obstruction of the glass brick sidewall by the shielding plate 23, making it easier for workers to remove the painted glass brick from the support plate 7. In addition, the position of the shielding plate 23 can be adjusted by adjusting the components so that after the shielding plate 23 has finished obstructing the glass brick sidewall, the top of the shielding plate 23 can be flush with the top of the glass brick. On the one hand, this allows the shielding plate 23 to completely obstruct the glass brick sidewall, and on the other hand, it can prevent the top of the shielding plate 23 from exceeding the top of the glass brick and interfering with the subsequent grinding mechanism 3. This makes the device applicable to glass bricks of different thicknesses.

[0034] Please see Figure 2 , Figure 4 and Figure 5 The extrusion component includes a stop plate 27 disposed below the support plate 7. The top of the stop plate 27 is fixed with push rods 25 arranged in a rectangle and capable of extruding the rotating plate 24. The push rods 25 all pass through the support plate 7 and are slidably connected to the support plate 7. Each push rod 25 is provided with a first spring 26. The two ends of the first spring 26 are fixedly connected to the bottom of the support plate 7 and the top of the stop plate 27, respectively. The bottom of the stop plate 27 is fixed with a stop rod 28. The column 1 is provided with an extrusion ring 21 that can extrude the stop rod 28. The extrusion ring 21 is fixedly connected to the column 1 through a fixing plate 22.

[0035] When the device sprays paint on glass bricks, the rotating ring 5 drives the support plate 7 to move in a circular motion around the column 1 via the connecting plate 6. The support plate 7 drives the abutment plate 27 and the abutment rod 28 to move in a circular motion via the push rod 25. The extrusion ring 21 is divided into a high layer and a low layer, and the connection between the high layer and the low layer is chamfered. Initially, the bottom of the abutment rod 28 is in contact with the low layer of the extrusion ring 21, and the extrusion ring 21 does not apply pressure to the abutment rod 28. When the support plate 7 rotates to a certain position, the chamfer at the connection between the high layer and the low layer extrudes the abutment rod 28. The abutment rod 28 drives the push rod 25 to move upward via the abutment plate 27. As the push rod 25 moves upward, it pushes the rotating plate 24, so that the shielding plate 23 can shield the side wall of the glass brick. When the lower end of rod 28 moves to the upper position, the pressure of the compression ring 21 on the abutment rod 28 no longer changes. At the same time, the baffle plate 23 is also in contact with the side wall of the glass brick, thus blocking the rotating side wall of the glass. After the glass brick is painted, as the rotating ring 5 continues to rotate, the abutment rod 28 will move to the bottom position of the compression ring 21 again. At this time, the pressure of the compression ring 21 on the abutment rod 28 decreases. The abutment plate 27 drives the push rod 25 to move downward under the action of the first spring 26. The push rod 25 no longer squeezes the rotating plate 24. The rotating ring 5 automatically resets under the action of the torsion spring 212, thereby releasing the baffle plate 23 from blocking the side wall of the glass brick, making it convenient for the staff to remove the painted glass brick from the support plate 7.

[0036] Please see Figure 5 The adjusting component includes a sliding groove disposed inside the rotating plate 24. A slider 29 is fixed on the side of the baffle plate 23 near the rotating plate 24. The end of the slider 29 away from the baffle plate 23 is located inside the sliding groove and is slidably connected to the sliding groove. A threaded rod 210 is rotatably connected inside the sliding groove. The threaded rod 210 passes through the slider 29 and is slidably connected to the slider 29. The threaded rod 210 passes through the side wall of the rotating plate 24 and is rotatably connected to the side wall of the rotating plate 24.

[0037] When spraying paint on glass bricks, the device can also rotate the threaded rod 210. Through the threaded connection between the threaded rod 210 and the slider 29, the baffle plate 23 is moved, thereby adjusting the position of the baffle plate 23. After the baffle plate 23 has finished covering the side wall of the glass brick, the top of the baffle plate 23 can be flush with the top of the glass brick, thus making the device applicable to glass bricks of different thicknesses.

[0038] Please see Figure 6 and Figure 7The grinding mechanism 3 includes telescopic rods 31 that are fixedly connected to the bottom of the first mounting plate 8 and are symmetrically distributed. A lifting plate 36 is fixed to the lower end of the telescopic rod 31. A rotating rod 35 passes through the inside of the lifting plate 36. The rotating rod 35 is connected to a rotating assembly, which is used to drive the rotating rod 35 to rotate. A rotating column 37 is fixed to the bottom of the rotating rod 35. Sandpaper 39 is covered at the bottom of the rotating column 37. A holding assembly 310 is provided on the side wall of the rotating column 37, which is used to fix the sandpaper 39. A moisturizing assembly is connected to the sandpaper 39, which is used to increase the humidity of the sandpaper 39.

[0039] When spraying paint on glass bricks, the device places the glass brick on top of the support plate 7 and drives the rotating ring 5 to rotate via an external rotating device. The rotating ring 5 drives the support plate 7 to move in a circular motion around the column 1 via the connecting plate 6. When the glass brick moves below the first mounting plate 8, the rotating ring 5 stops rotating. At this time, the telescopic rod 31 drives the lifting plate 36 to move downward. The lifting plate 36 drives the rotating column 37 to move downward via the rotating rod 35 until the sandpaper 39 covering the bottom of the rotating column 37 is in contact with the top of the glass brick. Then, the rotating assembly drives the rotating rod 35 to rotate. The rotating rod 35 drives the sandpaper 39 to rotate via the rotating column 37. The sandpaper 39 polishes the top of the glass brick, thereby damaging it. The smooth top of the glass brick creates a micro-roughness, which improves the adhesion of subsequent paint and ensures the painting effect. After the top of the glass brick is polished, the rotating component stops driving the rotating rod 35 to rotate, and the telescopic rod 31 drives the lifting plate 36 to move upward. Then, the rotating ring 5 drives the support plate 7 to continue rotating through the connecting plate 6. The sandpaper 39 is fixed by the holding component 310, which makes it convenient for the staff to replace the sandpaper 39. The holding component 310 can be a fastener, magnetic part or simple spring clip commonly used in the prior art, which will not be described in detail here. In addition, the moisturizing component can keep the sandpaper 39 moist, thereby improving the polishing effect of the sandpaper 39 on the top of the glass brick.

[0040] Please see Figure 6 The rotating assembly includes a motor 32 fixed to the top of the lifting plate 36. A rotating shaft is installed at the output end of the motor 32. The rotating shaft passes through the lifting plate 36 and is rotatably connected to the lifting plate 36. A first gear 33 is fixed at the bottom of the rotating shaft, and a second gear 34 is fixed outside the rotating rod 35. The first gear 33 and the second gear 34 mesh with each other.

[0041] When the glass block moves to below the first mounting plate 8, the rotating ring 5 stops rotating. At this time, the telescopic rod 31 drives the lifting plate 36 to move downward. The lifting plate 36 drives the rotating column 37 to move downward through the rotating rod 35 until the sandpaper 39 covering the bottom of the rotating column 37 is in contact with the top of the glass block. Then the motor 32 is started. The motor 32 drives the rotating shaft to rotate. The rotating shaft drives the first gear 33 to rotate. Through the meshing of the first gear 33 and the second gear 34, the rotating rod 35 is driven to rotate, which in turn enables the rotating column 37 to drive the sandpaper 39 to rotate, thereby achieving the grinding of the top of the glass block.

[0042] Please see Figure 6 and Figure 7 The moisturizing component includes a branch pipe 311 fixedly connected to the bottom of the first mounting plate 8. The lower end of the branch pipe 311 extends into the interior of the rotating rod and is rotatably connected to the inner wall of the rotating rod 35. The bottom of the rotating column 37 is provided with a water outlet 312. The interior of the rotating column 37 is provided with a cavity, which communicates with the water outlet pipe 314 and the inner cavity of the rotating rod 35. The bottom of the first mounting plate 8 is fixed with a pressure cylinder 317. A piston 316 is slidably connected inside the pressure cylinder 317. The bottom of the piston 316 is fixed with a support rod 38. The support rod 38 passes through the bottom of the pressure cylinder 317 and is fixedly connected to the lifting plate 36. A water inlet pipe 313 and a water outlet pipe 314 are connected below the piston 316 and on the side wall of the pressure cylinder 317. The water outlet pipe 314 communicates with the branch pipe 311. A water tank 315 is installed on the top of the first mounting plate 8. The water tank 315 communicates with the water inlet pipe 313.

[0043] When the glass brick moves below the first mounting plate 8, the rotating ring 5 stops rotating. At this time, the telescopic rod 31 drives the lifting plate 36 to move downward. As the lifting plate 36 moves downward, it drives the piston 316 to move downward through the support rod 38. As the piston 316 moves downward, it squeezes the water below it. The water enters the branch pipe 311 through the water outlet pipe 314, and then enters the cavity inside the rotating column 37 through the branch pipe 311 and the inner cavity of the rotating rod 35. Finally, it is discharged from the water outlet 312 at the bottom of the rotating column 37 and wets the sandpaper 39, thus effectively... The moisture content of the sandpaper 39 is maintained, which improves the polishing effect of the sandpaper 39 on the top of the glass brick. After the top of the glass brick is polished, the telescopic rod 31 drives the lifting plate 36 to move upward. The lifting plate 36 drives the piston 316 to move upward through the support rod 38. At this time, a negative pressure is formed below the piston 316, which then draws clean water from the water tank 315 through the water inlet pipe 313, so that the clean water in the water tank 315 can be stored again in the pressure cylinder 317. In order to ensure the unidirectional flow of clean water, both the water inlet pipe 313 and the water outlet pipe 314 are equipped with one-way valves.

[0044] Please see Figure 8The cleaning mechanism 4 includes a fixing block 410 fixedly connected to the bottom of the second mounting plate 9. The bottom of the fixing block 410 is provided with a plurality of air blowing pipes 411. The fixing block 410 has an air chamber inside. The air chamber is connected to the air blowing pipes 411 and is connected to an air intake component. The air intake component is used to inject hot air into the air chamber.

[0045] When the device is spraying paint on the glass brick, the glass brick is placed on top of the support plate 7, and the rotating ring 5 is driven to rotate by an external rotating device. The rotating ring 5 drives the support plate 7 to make a circular motion around the column 1 through the connecting plate 6. When the glass brick passes the bottom of the second mounting plate 9, the air intake component injects hot air into the air chamber inside the fixed block 410. The hot air is discharged through the air blowing pipe 411 at the bottom of the fixed block 410 and acts on the top of the glass brick. As the glass brick moves in a circular motion, the hot air discharged from the air blowing pipe 411 will sweep over the top of the glass brick, thereby cleaning the top of the glass brick. On the one hand, it can prevent the micro dust generated during the grinding process from adsorbing on the top of the glass brick and affecting the subsequent painting. On the other hand, it can also dry the top of the glass brick, further ensuring the adhesion of the subsequent paint.

[0046] Please see Figure 8 The air intake assembly includes a pneumatic cylinder 45 fixedly connected to the second mounting plate 9. A pneumatic rod 44 passes through the bottom of the pneumatic cylinder 45. A push plate 42 is fixed to the bottom of the pneumatic rod 44. A second spring 43 is fixed to the top of the push plate 42. The upper end of the second spring 43 is fixedly connected to the bottom of the pneumatic cylinder 45. A trapezoidal ring 41 capable of squeezing the push plate 42 is fixed to the top of the connecting plate 6. The pneumatic cylinder 45 is connected to an air inlet pipe 46 and an air outlet pipe 47. A heating box 48 is installed on the top of the second mounting plate 9. The heating box 48 is connected to the air outlet pipe 47. A connecting pipe 49 is connected to the side wall of the heating box 48. The other end of the connecting pipe is connected to the air cavity inside the fixed block 410.

[0047] When spraying paint onto glass bricks, the device places the glass bricks on top of the support plate 7 and rotates the rotating ring 5 via an external rotating device. The rotating ring 5, through the connecting plate 6, causes the support plate 7 to rotate around the column 1. When the glass bricks rotate to a certain position, the trapezoidal ring 41 at the top of the connecting plate 6 compresses the push plate 42. The push plate 42 drives the pneumatic rod 44 upward, which in turn compresses the gas inside the pneumatic cylinder 45. This gas then enters the heating chamber 48 through the outlet pipe 47, where it is heated. The heated gas enters the air chamber inside the fixed block 410 through the connecting pipe 49, and finally the high-temperature clean airflow is sprayed out by the blowing pipe 411 to blow away and dry the polishing dust on the top of the glass brick, thus completing the cleaning. When the hot air discharged from the blowing pipe 411 sweeps over the top of the glass brick, as the rotating ring 5 rotates, the trapezoidal ring 41 no longer squeezes the push plate 42, and the air pressure rod 44 automatically resets under the action of the second spring 43. At this time, a negative pressure is formed inside the air pressure cylinder 45, and then external gas is drawn out through the air inlet pipe 46. In order to ensure unidirectional gas flow, both the air inlet pipe 46 and the air outlet pipe 47 are equipped with one-way valves.

[0048] Working Principle: When spraying paint on glass bricks, the device places the glass bricks on top of the support plate 7. An external rotating device drives the rotating ring 5 to rotate. The rotating ring 5, through the connecting plate 6, drives the support plate 7 to rotate around the column 1. The support plate 7, through the push rod 25, drives the abutment plate 27 and the abutment rod 28 to rotate. The compression ring 21 is divided into a high layer and a low layer, with a chamfer at the connection between the high and low layers. Initially, the bottom of the abutment rod 28 contacts the low layer of the compression ring 21, and the compression ring 21 does not apply pressure to the abutment rod 28. When the support plate 7 rotates to a certain position, the chamfer at the connection between the high and low layers compresses the abutment rod 28. The abutment rod 28, through the abutment plate 27, drives the push rod 25 upward. Simultaneously, the upward movement of the push rod 25 pushes the rotating ring 7. The rotating plate 24 drives the shielding plate 23 to shield the side wall of the glass brick. When the lower end of the abutment rod 28 moves to the upper position, the pressure of the compression ring 21 on the abutment rod 28 no longer changes. At the same time, the shielding plate 23 is also in contact with the side wall of the glass brick. At this time, the shielding plate 23 provides shielding for the four sides of the glass brick, effectively preventing paint from contaminating the non-painted surfaces of the glass brick during subsequent painting. When the glass brick moves below the first mounting plate 8, the rotating ring 5 stops rotating. At this time, the telescopic rod 31 drives the lifting plate 36 to move downward. The lifting plate 36 drives the rotating column 37 to move downward through the rotating rod 35 until the sandpaper 39 covering the bottom of the rotating column 37 is in contact with the top of the glass brick. Then, the motor 32 is started. Machine 32 drives the rotating shaft to rotate, which in turn drives the first gear 33 to rotate. Through the meshing of the first gear 33 and the second gear 34, the rotating rod 35 rotates. The rotating column 37 drives the sandpaper 39 to rotate, thus polishing the top of the glass brick and damaging its smooth surface. This creates micro-roughness, improving the adhesion of subsequent paint and ensuring a good painting effect. Simultaneously, as the lifting plate 36 moves downward, it drives the piston 316 downward via the support rod 38. As the piston 316 moves downward, it squeezes the water below it. The water enters the branch pipe 311 through the water outlet pipe 314, and then flows through the branch pipe 311 and the inner cavity of the rotating rod 35 into the cavity inside the rotating column 37. Finally, it is discharged from the water outlet 312 at the bottom of the rotating column 37. The sandpaper 39 is then moistened, effectively ensuring its humidity and improving its polishing effect on the top of the glass brick. After the top of the glass brick is polished, as the rotating ring 5 continues to rotate, the trapezoidal ring 41 on the top of the connecting plate 6 squeezes the push plate 42. The push plate 42 drives the pneumatic rod 44 to move upward. As the pneumatic rod 44 moves upward, it squeezes the gas inside the pneumatic cylinder 45, causing the gas inside the pneumatic cylinder 45 to enter the heating box 48 through the air outlet pipe 47. The heating box 48 heats the gas, and the heated gas enters the air chamber inside the fixed block 410 through the connecting pipe 49. The hot gas is discharged through the air blowing pipe 411 at the bottom of the fixed block 410 and acts on the top of the glass brick. With the circumferential movement of the glass brick...The hot air exhausted from the air pipe 411 passes over the top of the glass block, thus cleaning it. This prevents dust generated during polishing from adhering to the top of the glass block and affecting subsequent painting, and also dries the top of the glass block, further ensuring good paint adhesion. When the glass block passes under the third mounting plate 10, the top of the glass block can be painted through the paint spray head 11 at the bottom of the third mounting plate 10.
