Description

Technical Field

[0001] This invention relates to the field of spraying equipment technology, specifically to an automatic release agent spraying system. Background Technology

[0002] Precast concrete components are concrete products that are manufactured in a standardized manner in a factory and assembled on site. Their core advantages are stable quality, short construction period, and green environmental protection. They are the core components of prefabricated buildings.

[0003] When manufacturing precast concrete components, a release agent needs to be sprayed onto the formwork surface to facilitate the separation of the formwork and the precast component after it has been formed. However, existing spraying equipment has the problem of atomized droplets spreading into the environment during spraying. The spread release agent can adhere to the surfaces of other uncast or just-setting components, significantly reducing the adhesion of coatings / mortars during subsequent painting, tiling, and decorative finishing, easily leading to peeling, hollowing, and detachment. Furthermore, the spread of the release agent can affect the health of workers. Therefore, in the current process of manufacturing precast concrete components, the release agent is generally applied manually. The specific method involves pouring the release agent onto the formwork and then manually spreading it evenly with a mop, similar to mopping the floor. This method of applying the release agent minimizes its spread during the application process, reducing the adverse effects caused by the spread of the release agent.

[0004] However, the above-mentioned method of applying release agent still has the following drawbacks: due to the large amount of labor involved in manual application, and the fact that manual operation cannot accurately repeat each operation as machine operation, the method of applying release agent manually has the problem of poor coating smoothness, which affects the smoothness of the surface of the precast components that are subsequently cast. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic release agent spraying system to solve the problems of large workload and poor coating surface smoothness in the prior art when manually applying release agent.

Furthermore, the nozzle frame is also equipped with a suction component, the air inlet of which is located inside the air curtain formed by the jet component, so as to discharge the air containing atomized droplets inside the air curtain and create a negative pressure in the space inside the air curtain.

[0007] Preferably, the nozzle frame is a rectangular box structure with an opening at the bottom, and the nozzle is disposed inside the nozzle frame; The jetting component includes a jet nozzle located at the lower edge of the nozzle frame, and an air inlet pipe is connected to the jet nozzle; The suction component includes an air extraction pipe installed at the upper end of the nozzle frame.

[0008] Preferably, during spraying, the direction of travel of the spray head assembly is forward, and the direction opposite to the direction of travel of the spray head assembly is backward, and a scraper is provided at the rear of the spray head frame; The nozzle located in front of the nozzle frame is tilted, and gradually tilts forward from top to bottom.

[0009] Preferably, a baffle is provided near the lower end of the scraper, and the baffle is located directly below the air nozzle behind the nozzle frame, so that the air ejected from the air nozzle behind the nozzle frame falls on the baffle.

[0010] Preferably, the baffle is sealed to the front of the scraper, and the height of the end where the baffle and scraper are connected is higher than the height of the lower end of the scraper.

[0011] Preferably, the baffle is disposed in front of the scraper, the baffle includes a connecting part, a connecting rod is disposed between the connecting part and the scraper, a blocking part is integrally disposed at the lower end of the connecting part, the blocking part is inclined and gradually inclined downward along the direction close to the scraper, there is a gap between the lower end of the blocking part and the scraper, and the height of the lower end of the blocking part is higher than the height of the lower end of the scraper, so that the air blown on the blocking part is guided by the blocking part and blown onto the scraper.

[0012] Preferably, the scraper is provided with a toothed groove at the position directly opposite the lower end of the blocking part, the length direction of the toothed groove is consistent with the width direction of the scraper, and the toothed groove extends from one side of the scraper to the other side of the scraper.

[0013] Preferably, the automatic release agent spraying system further includes an air source component, which includes an air box. The air box has a recovery chamber and an air supply chamber inside. The air supply chamber is sealed outside the recovery chamber. The suction pipe is connected to the recovery chamber, and the inlet pipe is connected to the air supply chamber. The air source assembly also includes an air pump, the air pump's inlet end being connected to the recovery chamber, and the air pump's outlet end being connected to the air supply chamber.

[0014] Preferably, the automatic release agent spraying system further includes a release agent tank, which is fixed to the lower part of the air box and connected to the spray nozzle.

[0015] Preferably, the automatic release agent spraying system further includes a walking component, which includes two opposing portal frames, a sliding frame slidably disposed between the two portal frames, a sliding table slidably disposed on the sliding frame, a rotating platform rotatably disposed on the sliding platform, a motor disposed on the sliding platform, the motor and the rotating platform being connected, an air box coaxially disposed at the lower part of the rotating platform, and a short column disposed between the air box and the rotating platform.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: 1. The automatic release agent spraying system of the present invention forms an air curtain around the nozzle, which blocks the atomized droplets generated during the spraying process from spreading to the environment outside the air curtain. At the same time, a suction component is also arranged on the nozzle frame to draw air from inside the air curtain, creating a directional airflow that continuously flows towards the air inlet of the suction component. The scattered atomized droplets are guided and constrained by the directional airflow and drawn into the suction component, further reducing the diffusion of atomized droplets during the spraying process. The improved spraying equipment can be used for the spraying of release agents during the production of precast concrete components without causing the problem of random diffusion of atomized droplets of release agent. Thus, the improved spraying equipment replaces manual application, solving the problems of high labor intensity and poor coating smoothness associated with manual application.

[0017] 2. Air curtains can block dust, atomized droplets, etc. from passing through, thus preventing the spread of atomized droplets. At the same time, the negative pressure environment can lock the atomized droplets, which also reduces the spread of atomized droplets. By improving the existing spraying equipment, a small-scale environment surrounded by an air curtain can be formed around the nozzle, and this small-scale environment can be kept under negative pressure. This innovative approach of modifying the small-scale environment around the nozzle solves the diffusion problem existing in traditional spraying equipment.

[0018] 3. The air nozzles behind the spray head frame are close to the scraper, and the lower end of the scraper is only a small distance from the template. While ensuring normal scraping operation, the lower end of the scraper is structurally optimized to prevent the air ejected from the air nozzles behind the spray head frame from acting on the template. At the same time, because the lower end of the scraper is very close to the template, the air curtain formed by the air nozzles behind the spray head frame also acts on the position very close to the template, ensuring the sealing effect of the air curtain at this point. This design concept utilizes the existing scraper layout characteristics and achieves the purpose of ensuring the sealing effect of the air curtain while avoiding the air curtain acting on the template and affecting the spraying effect through simple structural optimization.

[0019] 4. By guiding the air curtain's blowing direction at the scraper, the air curtain's force acts on the scraping position of the scraper, avoiding direct force from the air curtain onto the template where the release agent has just been sprayed. Simultaneously, the air curtain's force spreads excess release agent laterally, replenishing areas on the template where release agent is insufficient. The air curtain's force also sweeps away excess release agent from the scraping position, redistributing it and preventing release agent adhesion. Furthermore, due to the toothed design on the scraper, the air curtain sprayed onto the scraper does not impact the template downwards but flows along the inclined surface of the toothed grooves. Eventually, the air pressure gradually decreases until it reaches atmospheric pressure, preventing the air curtain from acting directly on the template's sprayed surface and causing uneven coating surface.

[0022] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0023] Example 1 In existing technologies, during the fabrication of precast concrete components, a release agent needs to be sprayed onto the formwork surface to facilitate the separation of the formwork and the precast component after molding. However, existing spraying equipment suffers from the problem of atomized droplets spreading into the environment during spraying. This diffused release agent adheres to the surfaces of other uncast, newly set components, significantly reducing the adhesion of coatings / mortars during subsequent painting, tiling, and decorative finishing, leading to peeling, blistering, and detachment. Furthermore, the diffusion of the release agent also affects the health of workers. Therefore, the fabrication of precast concrete components currently typically relies on manual labor. The specific method for applying the release agent is to pour the release agent onto the template and then manually spread it evenly with a mop, similar to mopping the floor. This method of applying the release agent prevents it from spreading too much, reducing the adverse effects caused by the spread. However, the manual application method still has the following drawbacks: due to the large amount of labor involved, and the fact that manual work cannot be as precise as machine work in repeating each operation, the coating smoothness is poor, affecting the smoothness of the surface of the precast components that are subsequently cast.

[0024] The core improvement of this embodiment lies in the fact that the air curtain can block dust, atomized droplets, etc. from passing through, thereby preventing the diffusion of atomized droplets. At the same time, the negative pressure environment can lock the atomized droplets, which also has the effect of reducing the diffusion of atomized droplets. By improving the existing spraying equipment, a small-scale environment surrounded by an air curtain is formed around the nozzle 12, and this small-scale environment is kept in a negative pressure state. The innovative idea of ​​modifying the small-scale environment around the nozzle 12 solves the diffusion problem existing in traditional spraying equipment. The improved spraying equipment can be used for the spraying of release agent during the production of precast concrete components without causing the problem of random diffusion of atomized droplets of release agent. In addition, the improved spraying equipment replaces manual application, solving the problems of high labor intensity and poor coating smoothness caused by manual application.

[0025] like Figures 1 to 4 as well as Figure 12 In this embodiment, an automatic mold release agent spraying system includes: The nozzle assembly 1 includes a nozzle holder 11, on which a nozzle 12 is disposed; Among them, the nozzle frame 11 is also equipped with air jetting elements 13 around the nozzle 12 to form an air curtain around the nozzle 12, and the spraying range of the nozzle 12 is within the air curtain. In addition, a suction component 14 is provided on the nozzle frame 11. The air inlet of the suction component 14 is located inside the air curtain formed by the jet component 13, so as to discharge the air containing atomized droplets inside the air curtain and create a negative pressure in the space inside the air curtain.

[0026] Working principle of automatic mold release agent spraying system: Figure 2 The nozzle holder 11 is used to mount the nozzle 12. At the same time, the nozzle holder 11 serves as a carrier to arrange air jets 13 around the nozzle 12 to form an air curtain around the nozzle 12. The air curtain blocks the atomized droplets generated during the spraying process from spreading to the environment outside the air curtain. Meanwhile, a suction component 14 is also arranged on the nozzle holder 11. The suction component 14 draws air from inside the air curtain, creating a directional airflow that continuously flows towards the air inlet of the suction component 14. Scattered atomized droplets are guided and constrained by the directional airflow and enter the suction component 14 to be sucked away, further reducing the diffusion of atomized droplets during the spraying process.

[0027] It should be noted that the suction component 14 creates a slight negative pressure in the space inside the air curtain, such as between -5 and -12 Pa. When the release agent is sprayed, it has a certain spraying pressure. After the release agent is atomized and sprayed out, most of it adheres to the template 5 to form a coating. The smaller atomized droplets of release agent and the rebounding release agent form a scattered and drifting pollution source. Since the suction component 14 is under slight negative pressure, it mainly sucks up the scattered and drifting pollution source part, while having almost no effect on the main deposition of the release agent with a certain spraying pressure.

[0028] It should be noted that, as with existing technology, the nozzle 12 sprays the release agent in a fan shape to ensure a certain spraying area. For the air jet 13, it sprays perpendicular to the template 5, and at the spraying surface of the template 5, the spraying range of the nozzle 12 is within the air curtain formed by the air jet 13. The outer edge of the spraying range of the nozzle 12 and the inner edge of the air curtain are a certain distance, such as 2-5cm, to avoid the air curtain and the sprayed release agent from contacting each other and affecting the deposition of the release agent.

[0029] It should be noted that the number of nozzles 12 on the nozzle holder 11 is designed according to the width of the template 5, so that the spraying range of the nozzles 12 covers the template 5 in the width direction, so as to complete the spraying operation of the entire template 5 in one spraying.

[0030] like Figure 2 and Figure 4 In this embodiment, the nozzle frame 11 is a rectangular box structure with an opening at the lower end, and the nozzle 12 is disposed inside the nozzle frame 11. The jet component 13 includes a jet nozzle 131 located at the lower edge of the nozzle frame 11, and an air inlet pipe 132 is connected to the jet nozzle 131. The suction component 14 includes an air extraction pipe 141 disposed at the upper end of the nozzle frame 11.

[0031] The nozzle holder 11 adopts a rectangular box structure with an opening at the bottom. Of course, except for the opening at the bottom of the nozzle holder 11, the rest of the nozzle holder 11 is sealed to prevent the atomized droplets from spreading outward at the nozzle holder 11. The bottom of the nozzle holder 11 is integrally provided with an outward flange for installing the air nozzles 131. That is, the air nozzles 131 are installed on the flange at the bottom of the nozzle holder 11. Specifically, the air nozzles 131 are evenly spaced on the flange, and the air sprayed by two adjacent air nozzles 131 partially overlaps to avoid diffusion gaps. The air extraction pipe 141 is specifically arranged at the top of the nozzle holder 11. Of course, the air extraction pipe 141 is connected to the space inside the air curtain.

[0032] like Figure 2 , Figure 3 and Figure 12 In this embodiment, during spraying, the direction of travel of the nozzle assembly 1 is forward, and the direction opposite to the direction of travel of the nozzle assembly 1 is backward. A scraper 15 is provided at the rear of the nozzle frame 11. The nozzle 131 located in front of the nozzle frame 11 is tilted, and gradually tilts forward in a downward direction.

[0033] By installing a scraper 15 on the nozzle holder 11, the sprayed coating is smoothed, improving the flatness of the release agent coating. Specifically, the scraper 15 is installed by setting a vertical strip hole on the scraper 15, inserting a bolt through the strip hole, and setting a screw hole on the nozzle holder 11. The bolt passes through the strip hole and is threaded into the screw hole. Tightening the bolt fixes the scraper 15. Through this design, the installation height of the scraper 15 can be adjusted to adapt to different spraying needs.

[0034] In addition, the air nozzle 131 located in front of the nozzle frame 11 is inclined. That is, when the release agent is sprayed, the air nozzle 131 located in front of the nozzle assembly 1 in the direction of movement is inclined. With this design, the air sprayed from the air nozzle 131 in front can be used to blow the template 5, improve the cleanliness of the template 5 surface during spraying, and thus improve the spraying quality. Of course, when the air nozzle 131 in front of the nozzle frame 11 is inclined, the distance between the air nozzles 131 on both sides of the nozzle frame 11 and the air nozzle 131 in front of the nozzle frame 11 can be adapted to ensure the air curtain in front of the nozzle frame 11 and the air curtain on both sides of the nozzle frame 11 are sealed and transitioned.

[0035] Example 2 It is understandable that in Embodiment 1, when the nozzle assembly 1 moves forward to spray, since the nozzle 12 is in front of the air nozzle 131 behind the nozzle holder 11, the air sprayed by the air nozzle 131 behind the nozzle holder 11 will fall on the coating just sprayed by the nozzle 12. Although the air pressure of the air sprayed by the air nozzle 131 is not high, it is only enough to maintain the air curtain sealing effect. However, the direct impact of the air on the coating will still cause the coating to deform, or even the release agent to splash, affecting the smoothness of the coating.

[0036] The core improvement of this embodiment lies in the fact that the air nozzle 131 behind the spray head frame 11 is close to the scraper 15, and the lower end of the scraper 15 is only a small distance away from the template 5. While ensuring the normal leveling operation of the scraper 15, the lower end of the scraper 15 is structurally optimized to prevent the air sprayed by the air nozzle 131 behind the spray head frame 11 from acting on the template 5. At the same time, since the lower end of the scraper 15 is very close to the template 5, the air curtain formed by the air nozzle 131 behind the spray head frame 11 also acts on the position very close to the template 5, ensuring the sealing effect of the air curtain at this location. This design concept utilizes the existing layout characteristics of the scraper 15 and achieves the purpose of ensuring the sealing effect of the air curtain and avoiding the air curtain acting on the template 5 and affecting the spraying effect through simple structural optimization.

[0037] like Figures 5 to 6 To solve the above problems, a baffle 16 is provided near the lower end of the scraper 15. The baffle 16 is located directly below the air nozzle 131 behind the nozzle frame 11, so that the air ejected from the air nozzle 131 behind the nozzle frame 11 falls on the baffle 16.

[0038] Working principle of baffle 16: Figure 5 The air ejected from the nozzle 131 behind the nozzle holder 11 moves downward to form an air curtain. When the air comes into contact with the baffle 16 near the lower end of the scraper 15, the baffle 16 blocks the air from moving further downward, thereby preventing the air ejected from the nozzle 131 behind the nozzle holder 11 from directly acting on the area of ​​the template 5 where the release agent has just been sprayed. This ensures the quality of the release agent spraying and reduces the impact of the air curtain on the spraying. This design, combined with the existing scraper 15 structure, only requires design optimization of the lower end structure of the scraper 15 to achieve the effect of scraping the coating while blocking the air from blowing directly onto the coating.

[0039] It should be noted that the baffle 16 and the scraper 15 form a hook-shaped structure with the opening of the hook-shaped part facing upward. The baffle 16 and the scraper 15 can be an integral structure designed as one piece, or they can be two independent parts that are fixedly connected. The specific fixed connection method can be bolt connection, riveting or welding.

[0040] like Figure 6 In this embodiment, the baffle 16 is sealed to the front of the scraper 15, and the height of the end where the baffle 16 and the scraper 15 are connected is higher than the height of the lower end of the scraper 15.

[0041] When the scraper 15 is working, the excess release agent scraped by the scraper 15 will move upward along the surface of the scraper 15. The connection position between the baffle 16 and the scraper 15 is close to the lower end of the scraper 15. When the scraped excess release agent moves upward and hits the baffle 16, the baffle 16 will block the scraped excess release agent from continuing to move upward. The scraped excess release agent and the baffle 16 will form a squeezing action. Through this squeezing action, the scraped excess release agent will spread laterally along the scraper 15, thereby making the scraped excess release agent replenish the adjacent laterally. This will replenish the release agent in the areas on the template 5 where the release agent spraying is less, improve the scraping effect of the scraper 15, and thus improve the spraying quality.

[0042] Example 3 It is understandable that in Embodiment 2, if the distance between the baffle 16 and the lower end of the scraper 15 is too far, the excess release agent scraped off will have difficulty moving to contact the baffle 16, and the excess release agent scraped off will have difficulty spreading laterally, thus failing to achieve the purpose of lateral redistribution of the excess release agent scraped off. If the distance between the baffle 16 and the lower end of the scraper 15 is too close, the space between the baffle 16 and the lower end of the scraper 15 will be small, making it difficult to accommodate the excess release agent scraped off, which will easily cause local accumulation of release agent, affecting the overall smoothness of the coating. Moreover, the excess release agent scraped off is easy to accumulate on the scraper 15 as dried residue, dirt or glue, which will cause uneven coating thickness and leave scratches on the coating.

[0043] The core improvement of this embodiment is that, unlike the blocking design of the air curtain at scraper 15 in Embodiment 2, the design of this embodiment is to guide the blowing direction of the air curtain at scraper 15, so that the wind force of the air curtain acts on the scraping position of scraper 15, avoiding the wind force of the air curtain acting directly on the template 5 that has just been sprayed with release agent. At the same time, the wind force of the air curtain is used to spread the excess release agent scraped off laterally, supplementing the insufficient release agent on the template 5. At the same time, the wind force of the air curtain is used to sweep the scraping position of scraper 15, promptly blowing away excess release agent for redistribution, and preventing the release agent from adhering to the scraping position of scraper 15.

[0044] like Figures 7 to 8 To solve the above problems, a baffle 16 is disposed in front of the scraper 15. The baffle 16 includes a connecting part 161, and a connecting rod 17 is disposed between the connecting part 161 and the scraper 15. A blocking part 162 is integrally disposed at the lower end of the connecting part 161. The blocking part 162 is disposed at an angle and gradually tilts downward along the direction close to the scraper 15. There is a gap between the lower end of the blocking part 162 and the scraper 15, and the height of the lower end of the blocking part 162 is higher than the height of the lower end of the scraper 15, so that the air blown on the blocking part 162 is guided by the blocking part 162 and blown onto the scraper 15. The scraper 15 is provided with a toothed groove 151 at the position directly opposite the lower end of the blocking part 162. The length direction of the toothed groove 151 is consistent with the width direction of the scraper 15, and the toothed groove 151 extends from one side of the scraper 15 to the other side of the scraper 15.

[0045] The working principle of the baffle 16 guiding the air curtain: as follows Figures 7 to 8 The air ejected from the nozzle 131 behind the nozzle holder 11 moves downwards and contacts the blocking part 162 of the baffle 16, reducing the air pressure of the air curtain. Because the blocking part 162 is inclined and its lower end faces the scraper 15, it guides the air curtain to move towards its lower end. Finally, the air curtain moves out of the blocking part 162 and sprays onto the scraper 15. A groove 151 is provided on the scraper 15 corresponding to the position where the air curtain is sprayed. Excess release agent scraped by the scraper 15 moves upwards along the surface of the scraper 15. The material moves into the tooth groove 151. Within the tooth groove 151, due to the shape of the tooth groove 151 and the blowing action of the air curtain, the excess release agent scraped off is more easily spread laterally within the tooth groove 151. This enhances the effect of lateral redistribution of the excess release agent and promotes the replenishment of release agent in areas where the amount of release agent sprayed is insufficient. At the same time, the air curtain's force acts on the scraper 15, making it easier for the excess release agent scraped off to spread laterally and flow downwards, preventing the excess release agent scraped off from accumulating on the scraper 15.

[0046] It should be noted that the air ejected from the nozzle 131 behind the nozzle holder 11 forms an air curtain. After the air curtain contacts the blocking part 162 of the baffle 16, the air pressure of the air curtain decreases. Subsequently, the air curtain moves out of the blocking part 162 and sprays onto the toothed groove 151 of the scraper 15. The air pressure of the air curtain decreases further. At the same time, due to the design of the toothed groove 151 on the scraper 15, the air curtain sprayed on the scraper 15 will not impact the template 5 downwards along the scraper 15, but will flow along the inclined surface of the toothed groove 151. During this process, the air pressure of the air curtain gradually decreases until it is balanced with atmospheric pressure, thus preventing the air curtain from acting on the spraying surface of the template 5.

[0047] Of course, such as Figures 9 to 10 The automatic release agent spraying system also includes an air source component 2, which includes an air box 21. The air box 21 is provided with a recovery chamber 211 and an air supply chamber 212. The air supply chamber 212 is sealed outside the recovery chamber 211. The air extraction pipe 141 is connected to the recovery chamber 211, and the air inlet pipe 132 is connected to the air supply chamber 212. The air source assembly 2 also includes an air pump 22, the air inlet of which is connected to the recovery chamber 211, and the air outlet of which is connected to the air supply chamber 212.

[0048] The air pump 22's air inlet is indirectly connected to the recovery chamber 211 and the air extraction pipe 141 to draw air from the inside of the air curtain. After the air containing atomized droplets is drawn into the recovery chamber 211, the atomized release agent is recovered by filtration. Alternatively, it can be removed by physical adsorption. The recovery chamber 211 has an exhaust port, through which the filtered or physically adsorbed clean air is discharged. The air pump 22's air outlet is connected to the air supply chamber 212 and the air inlet pipe 132 to provide air with a certain pressure to the air nozzle 131 to form the air curtain.

[0049] In addition, such as Figure 9 The automatic release agent spraying system also includes a release agent tank 3, which is fixed to the lower part of the air box 21 and connected to the spray nozzle 12.

[0050] The mold release agent tank 3 stores mold release agent. Specifically, the mold release agent tank 3 delivers the mold release agent to the nozzle 12 for spraying through a pressure pump. This is a mature method in the existing technology and will not be described in detail here.

[0051] Furthermore, such as Figure 11 The automatic release agent spraying system also includes a walking component 4, which includes two opposing portal frames 41, a sliding frame 42 slidably disposed between the two portal frames 41, a sliding table 43 slidably disposed on the sliding frame 42, a rotating table 44 rotatably disposed on the sliding table 43, a motor 45 disposed on the sliding table 43, the motor 45 and the rotating table 44 are connected, an air box 21 is coaxially disposed at the lower part of the rotating table 44, and a short column 46 is disposed between the air box 21 and the rotating table 44.

[0052] The traveling component 4 drives the spray nozzle component 1, the air source component 2, and the release agent tank 3 to move together for spraying operations.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed application.
