Description

Technical Field

[0001] This invention relates to the field of spraying technology, and more specifically to a demolding machine spraying equipment. Background Technology

[0002] Construction formwork is a tool used to assist in the setting and shaping of concrete during the construction of houses. With continuous technological improvements, aluminum alloy formwork has now largely replaced the original wooden formwork. In construction work, multiple aluminum alloy formworks need to be spliced ​​together to form a complete aluminum formwork frame, and concrete is poured inside the frame.

[0003] In existing technologies, due to the adhesive nature of concrete, a release agent needs to be applied to the surface of the aluminum alloy formwork to facilitate demolding. The formwork can only be installed after the release agent has dried. Currently, workers manually apply the release agent to the aluminum alloy formwork surface, which is physically demanding and prone to fatigue, thus reducing application efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a release agent spraying equipment that uses a mechanized approach to reduce manual labor intensity and improve spraying efficiency when spraying release agent.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0006] A mold release machine spraying device includes a bracket for placing an aluminum template, a door-shaped mounting plate slidably mounted on the bracket, an installation area between the mounting plate and the aluminum template, a spraying component connected to the mounting plate in the installation area, the spraying component being connected to a storage tank filled with a mold release agent via a first hose, a blowing component for blowing the surface of the aluminum template on the side of the spraying component, a grinding component for roughening the surface of the aluminum template on the side of the blowing component, a driving component for driving the mounting plate to move along the length of the bracket on one side of the mounting plate, and the first hose having a margin to accommodate the range of movement of the mounting plate.

[0007] In this solution, the aluminum template is placed on a support with the surface to be sprayed with the release agent facing upwards. Then, the grinding component is activated, and the drive component moves the mounting plate along the length of the aluminum template. The grinding component removes residual concrete or other debris from the surface of the aluminum template and also grinds the surface to the set roughness. While grinding, the blowing component blows away impurities from the surface of the aluminum template to ensure cleanliness. The rough surface is composed of countless tiny concave and convex structures, forming interconnected channels. After the surface of the aluminum template is ground, the spraying component is activated, and the drive component moves the mounting plate. The spraying component evenly sprays the release agent in the storage tank onto the surface of the aluminum template. The entire spraying process is basically mechanized. Compared with manual painting, the labor intensity of workers is lower, which helps to improve spraying efficiency.

[0008] The release agent fills the depressions on the rough surface, forming a continuous lubricating film. During subsequent reinforcement work, workers will pile steel and other materials on the aluminum formwork and walk around frequently. The constant friction between their feet and the aluminum formwork or the handling of steel can easily cause the release agent to fall off the formwork. The rough surface, by increasing the surface area and its uneven structure, allows the release agent to be more firmly anchored to the surface of the aluminum formwork, reducing the risk of falling off during construction. At the same time, it can also hinder the flow of the release agent, avoiding local accumulation or loss after spraying, forming a more uniform coating. This reduces the resistance to demolding later and avoids damage to the concrete surface. The rough surface also helps to expel air between the concrete and the formwork, reducing air bubble defects. At the same time, the lubricating effect of the release agent and the roughness work together to form a denser concrete surface layer.

[0009] Optionally, the support is inclined, with its upper end hinged to the upper floor slab. The upper floor slab has a transfer opening that allows the aluminum template to pass through. A fixed pulley is installed on the bottom surface of the upper floor slab, and a steel wire rope is threaded through the fixed pulley. One end of the steel wire rope is connected to the lower end of the support, and the other end is connected to a winch on the ground. The winch drives the support to transfer the aluminum template coated with release agent to the transfer opening.

[0010] Optionally, the grinding assembly includes a grinding motor and a grinding disc. The grinding motor is mounted on the bottom surface of the mounting plate, and the grinding disc is connected to the output end of the grinding motor. The grinding disc contacts the surface of the aluminum template, and the grinding motor drives the grinding disc to rotate to grind the surface of the aluminum template into a rough surface.

[0011] Optionally, a first hydraulic cylinder is provided between the grinding motor and the mounting plate. The output end of the first hydraulic cylinder faces vertically downward and is connected to a fixing plate. The fixing plate is connected to the housing of the grinding motor.

[0012] Optionally, multiple grinding motors are distributed on the fixing plate. The extension line of the long side of the fixing plate and the extension line of the short side of the mounting plate form an angle. The multiple grinding motors are spaced apart along the length of the fixing plate. The diameter of the grinding discs changes gradually along the length of the fixing plate. Adjacent grinding discs do not contact each other, but the grinding areas along the length of the aluminum template overlap. The grinding areas of the multiple grinding discs together cover the surface of the aluminum template.

[0013] Optionally, the grinding disc is a nylon abrasive grinding disc, the abrasive material is silicon carbide, the particle size is 80-120 mesh, and the surface roughness Ra of the aluminum template after grinding is 6-15μm.

[0014] Optionally, the top surface of the aluminum template is located above the top surface of the support.

[0015] Optionally, the spraying assembly includes a main spray pipe and a nozzle. The middle part of the main spray pipe is connected to one end of the first flexible hose. The nozzles are spaced apart on the bottom surface of the main spray pipe along its length. The two ends of the main spray pipe are closed. The top surface of the main spray pipe is connected to the bottom surface of the mounting plate. The spraying direction of the nozzles is perpendicular to the top surface of the aluminum template.

[0016] Optionally, the purging assembly includes an air duct connected to the side wall of the main nozzle, with both ends of the air duct closed. The air duct is located on the left side of the main nozzle, and a grinding assembly is located on the left side of the air duct. A second flexible hose is connected to the air duct and is connected to an external compressor. The second flexible hose has a margin to accommodate the movement range of the mounting plate. A purging port facing the surface of the aluminum template is provided on the side wall of the air duct.

[0017] Optionally, the mounting plate has a slider at the bottom and the bracket has grooves on both sides of the aluminum template. The slider is located in the grooves and the two ends of the grooves are closed. The drive assembly includes a second hydraulic cylinder, which is mounted on the bracket and the output end of the second hydraulic cylinder is connected to the side of the mounting plate.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. In this invention, the aluminum template is placed on the support, and then the grinding component is activated. The drive component drives the mounting plate to move along the length of the aluminum template. The grinding component removes residual concrete or other debris from the surface of the aluminum template and grinds the surface into a set rough surface. While grinding, the blowing component blows away impurities from the surface of the aluminum template to ensure surface cleanliness. The rough surface is composed of countless tiny concave and convex structures, forming interconnected channels. After the surface of the aluminum template is ground, the spraying component is activated. The drive component moves the mounting plate, and the spraying component evenly sprays the release agent in the storage tank onto the surface of the aluminum template. The entire spraying process is basically mechanized. Compared with manual painting, the labor intensity of workers is lower, which helps to improve spraying efficiency.

[0020] 2. After the release agent is sprayed onto the surface of the aluminum formwork, it fills the depressions of the rough surface, forming a continuous lubricating film. During subsequent reinforcement work, workers will pile steel and other materials on the aluminum formwork and walk around frequently. The constant friction between their feet and the aluminum formwork or the handling of steel can easily cause the release agent to fall off the aluminum formwork. The rough surface, by increasing the surface area and the uneven structure, makes the release agent more firmly anchored to the surface of the aluminum formwork, reducing the risk of falling off during construction. At the same time, it can also hinder the flow of the release agent, avoiding local accumulation or loss after spraying, forming a more uniform coating. This reduces the resistance to demolding later and avoids damage to the concrete surface. The rough surface also helps to expel air between the concrete and the formwork, reducing air bubble defects. At the same time, the lubricating effect of the release agent and the roughness work together to form a denser concrete surface layer.

[0021] 3. The winch can lift the support frame upwards. One end of the support frame is hinged to the upper floor slab. The support frame can rotate vertically at the hinge point, thereby lifting the aluminum template after spraying to the transfer port. Workers above can take out the aluminum template from the transfer port and place it in the designated position. This reduces the labor intensity of manual handling and improves the efficiency of transferring aluminum templates. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0035] A demolding machine spraying device includes a bracket 11 for placing an aluminum template 10. A door-shaped mounting plate 4 is slidably mounted on the bracket 11. An installation area 17 is provided between the mounting plate 4 and the aluminum template 10. A spraying component 5 connected to the mounting plate 4 is provided in the installation area 17. The spraying component 5 is connected to a storage tank 7 filled with a release agent through a first hose 29. A blowing component 9 for blowing the surface of the aluminum template 10 is provided on the side of the spraying component 5. A grinding component 3 for grinding the surface of the aluminum template 10 into a rough surface 27 is provided on the side of the blowing component 9. A driving component for driving the mounting plate 4 to move along the length direction of the bracket 11 is provided on one side of the mounting plate 4. The first hose 29 has a margin to adapt to the movement range of the mounting plate 4.

[0036] In this embodiment, as Figure 1As shown, the aluminum template 10 is placed on the support 11 with the surface to be sprayed with the release agent facing upwards. Then, the grinding component 3 is started, and the drive component drives the mounting plate 4 to move along the length of the aluminum template 10. The grinding component 3 removes residual concrete or other debris from the surface of the aluminum template 10 and grinds the surface into a set rough surface 27. While grinding, the blowing component 9 blows away impurities from the surface of the aluminum template 10 to ensure the surface is clean. The rough surface 27 is composed of countless tiny concave and convex structures 28, forming interconnected channels. After the surface of the aluminum template 10 is ground, the spraying component 5 is started, and the drive component moves the mounting plate 4. The spraying component 5 evenly sprays the release agent in the storage tank 7 onto the surface of the aluminum template 10. A booster pump can be used to pump the release agent from the storage tank 7 to the spraying component 5. The entire spraying process is basically mechanized. Compared with manual painting, the labor intensity of workers is lower, which helps to improve the spraying efficiency.

[0037] like Figure 8 As shown, the release agent fills the depressions of the rough surface 27, forming a continuous lubricating film. During subsequent reinforcement work, workers will pile steel and other materials on the aluminum formwork 10 and walk around frequently. The constant friction between their feet and the aluminum formwork 10 or the handling of steel can easily cause the release agent to fall off the aluminum formwork 10. The rough surface 27, by increasing the surface area and the uneven structure 28, makes the release agent more firmly anchored on the surface of the aluminum formwork 10, reducing the risk of falling off during construction. At the same time, it can also hinder the flow of the release agent, avoiding local accumulation or loss after spraying, forming a more uniform coating. This reduces the resistance to demolding later and avoids damage to the concrete surface. The rough surface 27 also helps to expel air between the concrete and the formwork, reducing air bubble defects. At the same time, the lubricating effect of the release agent and the roughness work together to form a denser concrete surface layer.

[0038] Furthermore, the support 11 is inclined, and the upper end of the support 11 is hinged to the upper floor slab 1. The upper floor slab 1 has a transfer port 2 that allows the aluminum template 10 to pass through. A fixed pulley 14 is installed on the bottom surface of the upper floor slab 1, and a steel wire rope 13 is threaded through the fixed pulley 14. One end of the steel wire rope 13 is connected to the lower end of the support 11, and the other end is connected to the winch 12 on the ground. The winch 12 drives the support 11 to transfer the aluminum template 10 sprayed with release agent to the transfer port 2.

[0039] Specifically, after the first floor of concrete is poured, the aluminum formwork 10 needs to be disassembled and transferred to the next floor for continued use through the transfer opening 2 on the floor slab. Currently, it is usually manually lifted to the transfer opening 2, and then the workers above carry it to the designated location. This results in high labor intensity for the workers and low transfer efficiency.

[0040] Therefore, in this application, if Figure 2As shown, one end of the support 11 is hinged to the bottom surface of the upper floor slab 1, allowing the support 11 to rotate at the hinge point. A fixed pulley 14 is installed on the bottom surface of the upper floor slab 1, and the winch 12 is fixed to the ground. One end of the steel wire rope 13 passes through the fixed pulley 14 and is connected to the bottom end of the support 11, while the other end is connected to the winch 12. The entire support 11 is tilted, and the aluminum template 10 is also tilted after being placed on the support 11. After the aluminum template 10 is sprayed, the winch 12 is started, and the winch 12 winds the steel wire rope 13. 3. The steel wire rope 13 drives the support 11 to rotate around the hinge point and move closer to the upper floor slab 1 until the aluminum formwork 10 is close to the transfer port 2. The worker can then touch the aluminum formwork 10 on the upper floor slab 1. The worker above can then transfer the sprayed aluminum formwork 10 to the designated position for installation. This reduces the manual lifting process, greatly reduces the labor intensity of the workers, and improves the transfer efficiency. This solution can realize both the spraying function and the transfer function of the aluminum formwork 10, thus improving the work efficiency.

[0041] Furthermore, the polishing assembly 3 includes a polishing motor 19 and a polishing disc 16. The polishing motor 19 is mounted on the bottom surface of the mounting plate 4, and the polishing disc 16 is connected to the output end of the polishing motor 19. The polishing disc 16 contacts the surface of the aluminum template 10, and the polishing motor 19 drives the polishing disc 16 to rotate to polish the surface of the aluminum template 10 into a rough surface 27.

[0042] Specifically, such as Figure 3 and Figure 4 As shown, the grinding assembly 3 mainly consists of a grinding motor 19 and a grinding disc 16. The output end of the grinding motor 19 faces downward and is mounted on the bottom surface of the mounting plate 4. The grinding motor 19 drives the grinding disc 16 to rotate, and the grinding disc 16 contacts the surface of the aluminum template 10, thereby achieving grinding of the surface of the aluminum template 10, removing stains and debris, and forming a rough surface 27. The rough surface 27 is composed of several spiral-shaped concave and convex structures 28. At the same time, the driving device drives the mounting plate 4 to move along the length direction of the bracket 11, so that the surface of the aluminum template 10 can be ground along the length direction.

[0043] Furthermore, a first hydraulic cylinder 21 is provided between the grinding motor 19 and the mounting plate 4. The output end of the first hydraulic cylinder 21 is vertically downward and connected to a fixing plate 20. The fixing plate 20 is connected to the outer shell of the grinding motor 19.

[0044] Specifically, the fixing plate 20 is installed on the bracket 11 on the side close to the upper floor slab 1. The first hydraulic cylinder 21 is installed on the bottom surface of the mounting plate 4. The telescopic end of the first hydraulic cylinder 21 is connected to the fixing plate 20. The first hydraulic cylinder 21 drives the fixing plate 20 to move in the direction of the aluminum template 10, so that the grinding disc 16 contacts the top surface of the aluminum template 10, thereby achieving grinding. After grinding, the fixing plate 20 is driven to drive the grinding motor 19 away from the aluminum template 10, so that the grinding disc 16 is separated from the aluminum template 10.

[0045] Furthermore, multiple grinding motors 19 are distributed on the fixing plate 20. The extension line of the long side of the fixing plate 20 and the extension line of the short side of the mounting plate 4 form an angle. The multiple grinding motors 19 are spaced apart along the length direction of the fixing plate 20. The diameter of the grinding discs 16 changes gradually along the length direction of the fixing plate 20. Adjacent grinding discs 16 do not contact each other, but the grinding areas 15 along the length direction of the aluminum template 10 overlap. The grinding areas 15 of the multiple grinding discs 16 together cover the surface of the aluminum template 10.

[0046] Specifically, such as Figure 6 As shown, in order to achieve one-time grinding of the surface of the aluminum template 10, multiple grinding motors 19 can be set up. The fixing plate 20 is set at an angle, and the multiple grinding motors 19 are distributed at intervals along the length direction of the fixing plate 20. The grinding discs 16 on each grinding motor 19 have different diameters. The diameter of the grinding discs 16 changes gradually along the length direction of the fixing plate 20. The grinding discs 16 do not contact each other. In two adjacent grinding discs 16, the grinding area 15 of the larger diameter grinding disc 16 overlaps with the grinding area 15 of the smaller diameter grinding disc 16. In this way, when multiple grinding discs 16 grind the surface of the aluminum template 10 along the length direction of the aluminum template 10, the surface of the aluminum template 10 can be completely covered in one go, avoiding the appearance of un-grinded areas 15 between two adjacent grinding discs 16. Taking three polishing discs 16 as an example, the upper polishing disc 16 has the smallest diameter, the middle polishing disc 16 has a slightly larger diameter, and the lower polishing disc 16 has the largest diameter. The polishing area 15 of the upper polishing disc 16 overlaps with the polishing area 15 of the middle polishing disc 16, and the polishing area 15 of the middle polishing disc 16 overlaps with the polishing area 15 of the lower polishing disc 16.

[0047] like Figure 7 As shown, the rough surfaces 27 in two adjacent grinding areas 15 partially overlap, creating an uneven structure 28 that forms interconnected channels. During concrete pouring, these channels provide escape paths for air, preventing air bubbles from being trapped at the interface between the formwork and the concrete. Smooth surfaces tend to form sealed interfaces, allowing air to escape upwards through the concrete, which can leave air bubbles inside. The raised portions of the rough surface 27 exert a micro-compression effect on the concrete slurry, promoting the rearrangement of slurry particles, reducing porosity, and increasing the density of the concrete surface layer. See the comparison results table below:

[0048] Template surface condition Number of bubbles (bubbles / m²) Surface porosity (%) 28-day compressive strength (MPa) Smooth surface + release agent 15~20 1.8~2.2 48~52 Rough surface + release agent 5~8 0.9~1.2 54~58

[0049] Furthermore, the grinding disc 16 is a nylon abrasive grinding disc, the abrasive material is silicon carbide, the particle size is 80-120 mesh, and the surface roughness Ra of the aluminum template 10 after grinding is 6-15μm.

[0050] Specifically, the roughness of surface 27 needs to be moderate. If it is too rough, mold release agent will remain, and if it is too fine, the air venting function will be lost.

[0051] Furthermore, the top surface of the aluminum template 10 is located above the top surface of the support 11.

[0052] Specifically, a pelvic cavity is formed inside the support 11, and the aluminum template 10 can be placed directly inside the pelvic cavity. The top surface of the aluminum template 10 is higher than the top surface of the support 11, which makes it easier to remove the aluminum template 10 later.

[0053] Furthermore, the spraying assembly 5 includes a main spray pipe 25 and a nozzle 26. The middle part of the main spray pipe 25 is connected to one end of the first flexible hose 29. The nozzles 26 are distributed at intervals along the length of the main spray pipe 25 on the bottom surface of the main spray pipe 25. The two ends of the main spray pipe 25 are closed. The top surface of the main spray pipe 25 is connected to the bottom surface of the mounting plate 4. The spraying direction of the nozzles 26 is perpendicular to the top surface of the aluminum template 10.

[0054] Specifically, a main spray pipe 25 with both ends closed is installed on the bottom surface of the mounting plate 4. The main spray pipe 25 is located on the right side of the grinding assembly 3. The main spray pipe 25 is connected to the storage tank 7 through the first hose 29. The length of the first hose 29 is moderate, which can accommodate the rotation of the bracket 11 and avoid being pulled and broken, and can also accommodate the movement of the mounting plate 4. Multiple nozzles 26 are distributed at intervals on the ground of the main spray pipe 25. The booster pump delivers the release agent from the storage tank 7 through the first hose 29 to the nozzles 26, and sprays it from the nozzles 26 onto the aluminum template 10. The mounting plate 4 moves along the length of the aluminum template 10 to achieve spraying on its surface.

[0055] Furthermore, the purging assembly 9 includes an air duct 23, which is connected to the side wall of the main nozzle 25. The air duct 23 is closed at both ends and is located on the left side of the main nozzle 25. The grinding assembly 3 is located on the left side of the air duct 23. A second flexible hose 30 is connected to the air duct 23 and is connected to an external compressor 8. The second flexible hose 30 has a margin to accommodate the movement range of the mounting plate 4. A purging port 24 facing the surface of the aluminum template 10 is provided on the side wall of the air duct 23.

[0056] Specifically, the air duct 23 is connected to the side of the main nozzle 25. The air duct 23 is closed at both ends and connected to the compressor 8 through the second hose 30. The length of the second hose 30 is moderate, which can accommodate the rotation of the bracket 11 and the movement of the mounting plate 4, and avoid being pulled and broken. The air duct 23 is located between the grinding assembly 3 and the main nozzle 25. The side of the air duct 23 is provided with a purge port 24. Multiple purge ports 24 are arranged at intervals along the length of the air duct 23. The purge ports 24 blow air downwards at an angle to purge the surface of the aluminum template 10 after grinding. Moreover, the aluminum template 10 is tilted during grinding, so that the debris is easily blown away. During the purge, the operator can wear a mask.

[0057] Further, such as Figure 5 and Figure 9 As shown, the mounting plate 4 has a slider 18 at its bottom end, and the bracket 11 has grooves 22 on both sides of the aluminum template 10. The slider 18 is located in the grooves 22, and the two ends of the grooves 22 are closed. The driving component includes a second hydraulic cylinder 6, which is mounted on the bracket 11. The output end of the second hydraulic cylinder 6 is connected to the side of the mounting plate 4.

[0058] The working principle of this invention is as follows: Initially, the entire support 11 is tilted. The worker places the aluminum template 10 to be sprayed tilted on the support 11, with the long side of the aluminum template 10 parallel to the long side of the support 11. Then, the grinding motor 19, the first hydraulic cylinder 21, and the second hydraulic cylinder 6 are started. The first hydraulic cylinder 21 drives the grinding disc 16 to contact the surface of the aluminum template 10, and then stops. The grinding motor 19 drives the grinding disc 16 to rotate to achieve grinding. At the same time, the second hydraulic cylinder 6 drives the mounting plate 4 to move along the length of the aluminum template 10, with the moving speed matching the grinding speed. Multiple grinding discs 16 cover the surface of the aluminum template 10 along its length, making the entire surface of the aluminum template 10 reach the desired roughness 27. During grinding, the compressor 8 is started, and the gas blown out through the blow port 24 blows away the impurities on the surface of the aluminum template 10. Grinding is then complete. Afterwards, the grinding motor 19 and compressor 8 stop, the first hydraulic cylinder 21 retracts, and at this time, the booster pump starts to deliver the release agent in the storage tank 7 to the nozzle 26. The second hydraulic cylinder 6 retracts, and the release agent is evenly sprayed onto the rough surface 27 until the rough surface 27 is completely sprayed. At this time, the mounting plate 4 is moved away from the placement range of the aluminum template 10 by the second hydraulic cylinder 6. The second hydraulic cylinder 6 stops, and the winch 12 starts. The winch 12 adopts a JK0.5-JK5 single drum winch 12. The winch 12 winds the steel wire rope 13 to drive the support 11 to rotate upward until the aluminum template 10 is close to the transfer port 2, so that the worker can directly contact the aluminum template 10. The length of the transfer port 2 can be appropriately increased to provide a passage area for the mounting plate 4. This can maximize the rotation of the support 11 to a horizontal position, making it easier for the worker to remove the aluminum template 10.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Based on the technical essence of the present invention, any simple modifications, equivalent substitutions, and improvements made to the above embodiments within the spirit and principles of the present invention shall still fall within the protection scope of the present invention.
