Description

Technical Field

[0001] This invention relates to the field of exterior wall spraying technology, and more specifically, to an intelligent exterior wall spraying machine with omnidirectional adjustable position. Background Technology

[0002] Exterior wall spraying is a common method of exterior wall decoration and protection during construction. After spraying, the exterior wall surface can present different textures and effects, such as real stone paint, elastic coating, and textured coating. This process can not only enhance the aesthetics of the building, but also increase the weather resistance and waterproofness of the exterior wall. When spraying exterior walls, an exterior wall spraying machine is required.

[0003] An exterior wall spraying machine is a machine used to spray paint on the exterior walls of buildings. It includes a paint bucket, a sprayer, a drive unit, and a slide rail. The paint bucket is installed on the sprayer. When spraying is required, the sprayer can be suspended on the side of the building's exterior wall, and the drive unit pushes the sprayer to move back and forth on the slide rail to achieve the effect of spraying the building's exterior wall.

[0004] In existing technologies, before spraying paint on the exterior walls of buildings, it is necessary to clean the surface of the exterior walls, remove various attachments, and make the wall surface smooth before spraying can be carried out. However, existing sprayers do not have the function of cleaning the wall surface in advance, and workers can only clean it with tools such as steel wool and scrapers, which is quite troublesome. If it is not cleaned, the paint on the wall surface is easy to fall off after spraying, and it will make the exterior wall surface uneven, affecting the aesthetics. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention proposes an intelligent spraying machine for building exterior walls with omnidirectional adjustable position.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a omnidirectional adjustable intelligent exterior wall spraying machine, comprising a machine body, a hanging rod fixedly connected to the top of the machine body, a support rod fixedly connected to the bottom of the machine body, a balance wheel rotatably connected to the bottom of the support rod, a storage tank threadedly connected to the top of the machine body, a hose provided at the bottom of the storage tank, a sprayer fixedly connected to the other side of the hose, a tray provided at the bottom of the sprayer, a micro motor provided on the inner wall of the tray, the bottom of the sprayer fixedly connected to the output end of the micro motor, a spray pipe threadedly connected to one side of the sprayer, a scraping component for cleaning the exterior wall provided on one side of the machine body, a limiting component for limiting the spraying range provided on one side of the machine body, a spraying component for wetting the exterior wall provided on one side of the tray, a cleaning component for cleaning the hose provided on the inner wall of the hose, and a mixing component for mixing the paint provided at the top of the storage tank.

A rotary motor is fixedly connected to one side of the sliding frame, and a reciprocating lead screw is fixedly connected to the output end of the rotary motor. The reciprocating lead screw is disposed on the inner wall of the sliding frame, and a ball nut is slidably connected to the outer wall of the reciprocating lead screw. The top end of the ball nut is fixedly connected to the bottom of the support plate. Push rods are fixedly connected to both sides of the machine body, and a limiting plate is fixedly connected to the output end of the push rod. The sliding frame passes through the limiting plate, and a limiting block is fixedly connected to the inner wall of the limiting plate. The limiting block is sleeved on the outer wall of the reciprocating lead screw. A bracket is fixedly connected to one side of the limiting block, and a limiting wheel is rotatably connected to the side of the bracket away from the limiting block. A detection head is fixedly connected to the top of the sprayer.

[0008] Furthermore, the scraping assembly includes a toothed plate fixed to one side of the slide frame, a hoop fixed to one side of the support plate, a rotating rod rotatably connected to the inner wall of the hoop, a gear fixed to the outer wall of the rotating rod, the gear meshing with one side of the toothed plate, a striking plate fixed to one side of the rotating rod, the striking plate being made of rubber, a base plate fixed to the bottom of the support plate, a scraper fixed to one side of the base plate, a transmission rod fixed to the top of the base plate, the transmission rod being L-shaped, and the bottom of the transmission rod being located on the side of the base plate near the scraper.

[0009] Furthermore, the spraying assembly includes a water tank fixed to the bottom of the base plate, a connecting pipe fixed to the top of the water tank, the bottom of the connecting pipe extending into the inner wall of the water tank, a rotating rod rotatably connected to the top of the connecting pipe, a transmission rod fixed to the bottom of the rotating rod, the bottom of the transmission rod extending into the inner wall of the connecting pipe, a conveying plate fixed to the outer wall of the transmission pipe, the conveying plate being spiral-shaped and made of rubber, the outer wall of the conveying plate being tightly attached to the inner wall of the connecting pipe, a transmission pipe fixed to the top of one side of the connecting pipe, a sprayer fixed to the bottom of the base plate, and the end of the transmission pipe away from the connecting pipe fixed to one side of the sprayer.

[0010] Furthermore, the cleaning assembly includes a drain pipe fixed to the top of the machine body and located at the bottom of the storage tank. A scraper is provided at the top of the drain pipe, the circumference of which is greater than the circumference of the inner wall of the drain pipe. A rubber strip passes through the center of the scraper, and a threaded rod is fixed to the top of the rubber strip. A threaded cap is threaded to the outer wall of the threaded rod and is located at the top of the scraper. The bottom of the rubber strip extends into the inner wall of the spray nozzle, which has a groove. A protrusion is slidably connected to the inner wall of the groove, and a pulling piece is fixed to the inner wall of the protrusion. The rubber strip is fixed to the center of the pulling piece.

[0011] Furthermore, the stirring assembly includes a filter screen, which is fixed to the bottom of the storage tank. A stirring rod is rotatably connected to the center of the filter screen. A top rod is fixed to the top of the stirring rod. A connecting plate is fixed to the outer wall of the top rod. The side of the connecting plate away from the top rod is sleeved on the top of the rotating rod. A support plate is fixed to the outer wall of the rotating rod. The support plate is disposed at the bottom of the connecting plate.

[0012] Furthermore, a top block is fixed to the top of the detection head, and a scraper is rotatably connected to the inner wall of the top block via a rotating shaft. The end of the scraper away from the rotating shaft extends out of the inner wall of the top block, and a spring is fixed to the inner wall of the top block. The side of the spring away from the top block is fixed to the scraper.

[0013] The technical effects and advantages of the intelligent building exterior wall spraying machine with omnidirectional adjustable position according to the present invention are as follows:

[0014] (1) By setting up a scraper plate, the scraper plate can be driven to move closely against the wall when the base plate moves back and forth with the support plate. When the scraper plate moves, it can remove the attached objects on the wall. At the same time, the hoop on one side of the support plate can drive the rotating rod and gear to rotate while moving, and drive the striking plate to rotate together. When the striking plate hits the transmission rod, it vibrates, and the vibration is transmitted to the scraper plate, which adds a vibration effect to the scraper plate, thus making it more conducive to removing the attached objects on the wall. Since the material of the striking plate is rubber, it can be easily moved away from one side of the transmission rod, which is beneficial for the next striking treatment.

[0015] (2) By setting a transmission rod and a conveyor plate at the bottom of the rotating rod, the transmission rod and the conveyor plate can be rotated together when the rotating rod rotates, thereby drawing water from the water tank to the upper part of the inner wall of the connecting pipe, which can supply water to the sprayer. Water mist can be sprayed on the wall surface through the sprayer. Since the sprayer is set at the bottom of the shovel plate, water mist can be sprayed on the wall surface in advance, which can soften the wall surface and make it easier to remove the surface. The water mist can keep the wall moist and prevent the paint layer from cracking and peeling due to the wall being too dry. At the same time, the characteristics of the conveyor plate can make the gear only spray water once during one reciprocating motion, which can prevent the water mist from being sprayed out too much and causing the wall surface to be too wet, making it easier to control the humidity of the wall surface within a suitable range.

[0016] (3) By installing a rubber strip inside the spray pipe, when the spray pipe needs to be removed for cleaning after the spraying operation is completed, the rubber strip and scraper can be moved together by pulling the spray pipe outward. When the scraper moves to one side, it can scrape off the paint residue on the inner wall of the hose, thus cleaning the inner wall of the hose and preventing the paint from solidifying inside the hose.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Reference Figure 1-12 The system includes a machine body 1, a hanging rod 2 fixedly connected to the top of the machine body 1, a support rod 3 fixedly connected to the bottom of the machine body 1, a balance wheel 4 rotatably connected to the bottom of the support rod 3, a storage tank 5 threadedly connected to the top of the machine body 1, a hose 6 provided at the bottom of the storage tank 5, a sprayer 8 fixedly connected to the other side of the hose 6, a support plate 7 provided at the bottom of the sprayer 8, a micro motor provided on the inner wall of the support plate 7, the bottom of the sprayer 8 fixedly connected to the output end of the micro motor, a spray pipe 9 threadedly connected to one side of the sprayer 8, a scraping component for cleaning the exterior wall provided on one side of the machine body 1, a limiting component for limiting the spraying range provided on one side of the machine body 1, a spraying component for wetting the exterior wall provided on one side of the support plate 7, a cleaning component for cleaning the hose 6 provided on the inner wall of the hose 6, and a mixing component for mixing the paint provided at the top of the storage tank 5.

[0034] To address the issue of inconvenient wall cleaning before spraying, when spraying is required, the mixed paint is poured into storage tank 5, and a winch is used to hook the steel cable onto boom 2. The machine body 1 is then placed on one side of the exterior wall, and balance wheels 4 keep it sliding downwards. By incorporating a limiting component, the trajectory of the sprayer 8 can be restricted according to the spraying area, ensuring that the sprayer 8 can only spray the designated area. Before spraying, the spraying component can be used to spray the wall below, softening any adhering substances and making them easier to remove. This also helps control the wall's moisture content, allowing the paint to adhere better to the wall surface. The surface is less prone to bubbling and cracking. The scraping component above can then be used to remove protruding deposits from the wall, making the surface smoother. The paint from the storage tank 5 is then fed into the sprayer 8 via the hose 6 and sprayed out through the nozzle 9, allowing for wall painting. The detection head 17 can observe any missed areas on the wall. A micro motor allows for fine-tuning of the spraying direction. A stirring component agitates the paint in the storage tank 5 during spraying, preventing large particles from clogging the spray nozzle. After spraying, the cleaning component removes the paint from the hose 6 and sprayer 8, preventing hardening and blockage of the hose 6.

[0035] Reference Figure 1-2 The limiting assembly includes a sliding frame 14, which is fixedly connected to one side of the machine body 1. A rotary motor 13 is fixedly connected to one side of the sliding frame 14. A reciprocating screw 15 is fixedly connected to the output end of the rotary motor 13. The reciprocating screw 15 is disposed on the inner wall of the sliding frame 14. A ball nut 16 is slidably connected to the outer wall of the reciprocating screw 15. The top end of the ball nut 16 is fixedly connected to the bottom of the support plate 7. Push rods are fixedly connected to both sides of the machine body 1. A limiting plate 10 is fixedly connected to the output end of the push rod. The sliding frame 14 passes through the limiting plate 10. A limiting block 18 is fixedly connected to the inner wall of the limiting plate 10. The limiting block 18 is sleeved on the outer wall of the reciprocating screw 15. A bracket 11 is fixedly connected to one side of the limiting block 18. A limiting wheel 12 is rotatably connected to the side of the bracket 11 away from the limiting block 18. A detection head 17 is fixedly connected to the top of the sprayer 8.

[0036] When the area to be sprayed needs to be defined, the distance between the two sets of limiting plates 10 can be adjusted by controlling the two sets of push rods. The inner wall of the limiting plate 10 is provided with limiting blocks 18, which can limit the movement of the ball nut 16 by limiting blocks 18 sleeved on the reciprocating screw 15. The bracket 11 and limiting wheel 12 provided on one side of the limiting plate 10 can align the limiting plate 10 with the right angle surface of the wall. When encountering a concave surface of the building, the two sets of outer limiting wheels 12 can abut against the two sides of the concave surface of the building. When encountering a convex surface of a building, two sets of inner limit wheels 12 can be used to clamp the two sides of the convex surface of the building, which makes it easy to limit the movement of the machine body 1. When spraying is required, the rotary motor 13 can be started, which drives the reciprocating screw 15 to rotate and drive the ball nut 16 on the reciprocating screw 15 to slide on the slide frame 14. This allows the sprayer 8 and the spray pipe 9 to slide back and forth within a specified range on the slide frame 14, so that the designated area of ​​the building exterior wall can be sprayed.

[0037] Reference Figure 1-4 The scraping assembly includes a toothed plate 19, which is fixedly connected to one side of the slide frame 14. A hoop 20 is fixedly connected to one side of the support plate 7. A rotating rod 21 is rotatably connected to the inner wall of the hoop 20. A gear 22 is fixedly connected to the outer wall of the rotating rod 21. The gear 22 meshes with one side of the toothed plate 19. A striking plate 23, made of rubber, is fixedly connected to one side of the rotating rod 21. A base plate 24 is fixedly connected to the bottom of the support plate 7. A scraper plate 26 is fixedly connected to one side of the base plate 24. A transmission rod 25, which is L-shaped, is fixedly connected to the top of the base plate 24 near the scraper plate 26.

[0038] During the spraying operation, the pallet 7 reciprocates with the ball nut 16, thus moving the base plate 24 and scraper 26. The scraper 26 removes the attached material from the wall during this movement. Simultaneously, a hoop 20 on one side of the pallet 7 drives the rotating rod 21 and gear 22 to move together with the pallet 7. The gear 22 meshes with the rack, so as it moves, it rotates on one side of the rack, causing the rotating rod 21 to rotate as well. When the rotating rod 21 rotates, it drives the bottom-mounted beater... The plate 23 rotates, and when the striking plate 23 strikes the transmission rod 25, the transmission rod 25 vibrates. This vibration is then transmitted to the scraper plate 26, giving the scraper plate 26 an additional vibration effect, which makes it easier to remove the attachments on the wall. Since the striking plate 23 is made of rubber, when the striking plate 23 strikes the transmission rod 25, it will shift due to the material of the striking plate 23. After striking, the rubber striking plate 23 will return to its original position, which is beneficial for the next striking process.

[0039] Reference Figure 3-7 The spraying assembly includes a water tank 27, which is fixed to the bottom of a base plate 24. A connecting pipe 43 is fixed to the top of the water tank 27, and the bottom of the connecting pipe 43 extends into the inner wall of the water tank 27. A rotating rod 21 is rotatably connected to the top of the connecting pipe 43, and a transmission rod 28 is fixed to the bottom of the rotating rod 21. The bottom of the transmission rod 28 extends into the inner wall of the connecting pipe 43. A conveying plate 29 is fixed to the outer wall of the transmission pipe 30. The conveying plate 29 is spiral in shape and made of rubber. The outer wall of the conveying plate 29 is in close contact with the inner wall of the connecting pipe 43. The top of one side of the connecting pipe 43 is fixed to the transmission pipe 30. A sprayer 31 is fixed to the bottom of the base plate 24, and the end of the transmission pipe 30 away from the connecting pipe 43 is fixed to one side of the sprayer 31.

[0040] Before spraying, add clean water to the water tank 27. When the rotating rod 21 rotates, it drives the bottom transmission rod 28 to rotate as well. The rotation of the transmission rod 28 causes the outer conveyor plate 29 to move along with it. The connecting pipe 43 is fixed to the top of the water tank 27, so it does not rotate with the transmission rod 28. Since the conveyor plate 29 is spiral-shaped and the bottoms of both the transmission rod 28 and the conveyor plate 29 extend into the water tank 27, it is easy to extract water from the tank. Because the conveyor plate 29 is made of rubber and fits tightly against the inner wall of the connecting pipe 43, when the conveyor plate 29 rotates, water can spirally rise from the water tank 27 to the top of the connecting pipe 43, facilitating the... Water is transferred to the transmission pipe 30, which in turn sends water to the sprayer 31. The sprayer 31 then sprays water mist onto the wall. Since the sprayer 31 is located at the bottom of the scraper plate 26, the wall can be sprayed with water mist in advance, which softens the adhering substances on the wall and makes them easier to remove. The water mist also keeps the wall moist, preventing the paint layer from cracking and peeling due to excessive dryness. When the support plate 7 slides in the opposite direction, the transmission rod 28 and the conveyor plate 29 rotate in the opposite direction, preventing the water from flowing upward. This prevents the sprayer 31 from spraying water mist, thus preventing excessive water mist from making the wall too wet and keeping the humidity of the wall within a suitable range.

[0041] Reference Figure 8-12The cleaning assembly includes a drain pipe 32, which is fixed to the top of the machine body 1 and located at the bottom of the storage tank 5. A scraper 34 is provided at the top of the drain pipe 32, and the circumference of the scraper 34 is greater than the circumference of the inner wall of the drain pipe 32. A rubber strip 33 passes through the center of the scraper 34, and a threaded rod is fixed to the top of the rubber strip 33. A threaded cap is threaded to the outer wall of the threaded rod and is located at the top of the scraper 34. The bottom of the rubber strip 33 extends into the inner wall of the spray pipe 9, and a groove is provided in the inner wall of the spray pipe 9. A protrusion 36 is slidably connected to the inner wall of the groove, and a pulling piece 35 is fixed to the inner wall of the protrusion 36. The rubber strip 33 is fixed to the center of the pulling piece 35.

[0042] When the spray nozzle 9 needs to be installed, the threaded end of the rubber strip 33 can be inserted into the sprayer 8 and the hose 6 until the threaded rod protrudes from the drain tube 32 at the top of the hose 6. Then, the scraper 34 can be passed through the center of the threaded rod and installed at the top of the drain tube 32 with the threaded cap. During the spraying operation, the paint can flow into the hose 6 through the multiple holes provided on the drain tube 32. The pull plate 35 is rotatably connected to the spray nozzle 9 through the protrusion 36, which can facilitate the connection between the pull plate 35 and the rubber strip 33 when the spray nozzle 9 is rotated for installation and removal. After the spraying operation, the spray nozzle 9 can be rotated out and then pulled. The rubber strip 33 and the scraper 34 can be moved together at the same time. When the scraper 34 moves, it can scrape out the paint remaining in the hose 6, thereby preventing the paint from solidifying in the hose 6.

[0043] Reference Figure 8-11 The stirring assembly includes a filter screen 42, which is fixed to the bottom of the storage tank 5. A stirring rod 41 is rotatably connected to the center of the filter screen 42. A top rod is fixed to the top of the stirring rod 41. A connecting plate 37 is fixed to the outer wall of the top rod. The side of the connecting plate 37 away from the top rod is sleeved on the top of the rotating rod 21. A support plate is fixed to the outer wall of the rotating rod 21. The support plate is located at the bottom of the connecting plate 37.

[0044] By installing a filter screen 42 at the bottom of the storage tank 5, the unmixed paint can be trapped in the storage tank 5 during the spraying operation, preventing the unmixed paint from clogging the hose 6. When the rotating rod 21 moves back and forth with the pallet 7, the rotating rod 21 will drive the top connecting plate 37 to rotate. The bottom of the connecting plate 37 is fixedly connected to the top rod and the stirring rod 41. Therefore, when the connecting plate 37 rotates back and forth, it will drive the stirring rod 41 to rotate back and forth as well, which can keep the paint in the storage tank 5 in a stirred state and help to mix the paint evenly.

[0045] Reference Figure 1-6The top of the detection head 17 is fixedly connected to a top block 38. The inner wall of the top block 38 is rotatably connected to a scraper 40 via a rotating shaft. The end of the scraper 40 away from the rotating shaft extends out of the inner wall of the top block 38. A spring 39 is fixedly connected to the inner wall of the top block 38. The side of the spring 39 away from the top block 38 is fixedly connected to the scraper 40.

[0046] When the detection head 17 moves back and forth with the tray 7, it can drive the top block 38 at the top of the tray 7 to move together. Due to inertia, the scraper 40 set inside the top block 38 will shift in the opposite direction of the movement of the tray 7, and at the same time squeeze the spring 39 on one side. When the scraper 40 moves against the wall, it will move back and forth on the wall after spraying to prevent the paint from being sprayed too thickly on some parts of the wall.

[0047] Working Principle: To address the issue of inconvenient wall cleaning before spraying, the mixed paint is poured into storage tank 5 before spraying. Two sets of push rods are used to adjust the distance between two sets of limiting plates 10. Limiting blocks 18 are installed on the inner wall of each limiting plate 10, which restrict the movement of the ball nut 16 by fitting onto the reciprocating screw 15. A bracket 11 and limiting wheels 12 on one side of the limiting plate 10 align the limiting plate 10 with the right-angled surface of the wall. When encountering a concave surface, the two outermost limiting wheels 12 abut against the sides of the concave surface; when encountering a convex surface, the two innermost limiting wheels 12 clamp the sides of the convex surface, facilitating the positioning of the machine. The movement position of the main body 1 is limited, and the steel cable hook is hung on the boom 2 by a winch. Then, the main body 1 is placed on one side of the outer wall, and the balance wheel 4 keeps the main body 1 sliding downward. When spraying is required, the rotary motor 13 can be started, which drives the reciprocating screw 15 to rotate, and drives the ball nut 16 on the reciprocating screw 15 to slide on the slide frame 14. This allows the pallet 7, sprayer 8 and spray pipe 9 to slide back and forth within a specified range on the slide frame 14. Then, the paint in the storage tank 5 can be flowed into the sprayer 8 through the hose 6, and the paint can be sprayed out through the spray pipe 9 to spray the wall. The filter screen 42 can trap the insufficiently stirred paint in the storage tank 5 to prevent the paint from being not stirred properly. The evenly mixed paint clogs the hose 6. The area of ​​missed spraying on the wall can be observed through the detection head 17. A micro motor allows for fine-tuning of the spraying direction. A clamp 20 on one side of the tray 7 drives the rotating rod 21 and gear 22 to move together with the tray 7. The gear 22 meshes with the rack, so as it moves, it rotates on one side of the rack, causing the rotating rod 21 to rotate as well. When the rotating rod 21 rotates, it drives the bottom transmission rod 28 and conveyor plate 29 to move together. Since the conveyor plate 29 is spiral-shaped, and the bottoms of both the transmission rod 28 and the conveyor plate 29 extend into the water tank 27, it facilitates the extraction of water from the tank 27. Because the conveyor plate 29 is made of rubber and fits tightly against the inner wall of the connecting pipe 43, it... When the conveyor plate 29 rotates, water spirals upward from the water tank 27 to the top of the connecting pipe 43, facilitating its transfer to the transmission pipe 30. The transmission pipe 30 then delivers water to the sprayer 31, allowing water mist to be sprayed onto the wall. Since the sprayer 31 is located at the bottom of the scraper plate 26, water mist can be sprayed onto the wall in advance, softening any adhering substances and making them easier to remove. The water mist also keeps the wall moist, preventing the paint layer from cracking and peeling due to excessive dryness. When the support plate 7 slides in the opposite direction, the transmission rod 28 and the conveyor plate 29 rotate in opposite directions, preventing water from flowing upwards. This prevents the sprayer 31 from spraying water mist excessively, thus preventing the wall from becoming too wet.To facilitate controlling the humidity of the wall surface within a suitable range, the reciprocating movement of the support plate 7 drives the bottom plate 24 and scraper plate 26 to move as well. The scraper plate 26 removes the attached substances from the wall surface during movement. The rotating rod 21, when rotating, drives the bottom-mounted striking plate 23 to rotate as well. When the striking plate 23 strikes the transmission rod 25, it causes the transmission rod 25 to vibrate, thus transmitting the vibration to the scraper plate 26, adding a vibration effect to the scraper plate 26, which is more effective at removing the attached substances from the wall surface. Because the striking plate 23 is made of rubber, when it strikes the transmission rod 25, the striking plate 23 will shift due to its material. After striking, the rubber striking plate 23 will return to its original position, facilitating the next striking process. As the rotating rod 21 reciprocates along with the support plate 7, it drives the top connecting plate 37 to rotate. The bottom of the connecting plate 37 is fixedly connected to the top rod and the stirring rod 41. Therefore, when the connecting plate 37 reciprocates, it drives the stirring rod 41 to reciprocate as well, which helps to keep the paint in the storage tank 5 in a stirred state and facilitates uniform mixing of the paint. When the pallet 7 moves back and forth, it can drive the top block 38 to move together. Due to inertia, the scraper 40 installed inside the top block 38 will shift in the opposite direction of the movement of the pallet 7, while squeezing the spring 39 on one side. When the scraper 40 moves along the wall, it will move back and forth on the sprayed wall surface to prevent the paint from being sprayed too thickly on some parts of the wall. After the spraying operation is completed, the spray pipe 9 can be rotated out and then pulled. This will simultaneously pull the rubber strip 33 and the scraper 34 to move together. When the scraper 34 moves, it can scrape out the paint remaining in the hose 6, thereby preventing the paint from solidifying in the hose 6 and facilitating the next spraying operation.
