Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of surface coating, specifically a spraying device for demolding lightweight wall panels. Background Technology
[0002] Lightweight wall panels are a type of lightweight partition wall panel commonly used in recent years. They are made of lightweight materials or have a lightweight structure, and have tenons, mortises, and joint grooves on both sides. They are prefabricated panels used for non-load-bearing interior partition walls in industrial and civil buildings. The production of lightweight wall panels mainly involves casting in molds. After the concrete hardens, the panels are removed from the molds for subsequent curing, cutting, and other operations to obtain the finished lightweight wall panels.
[0003] To facilitate the demolding of concrete from the mold, a release agent needs to be sprayed into the mold before pouring. In existing technology, a nozzle is installed, and when the mold is below the nozzle, the nozzle is controlled to move along the length of the mold, completing two sprays of release agent in one round trip. However, because lightweight wall panels have tenons, mortises, and joint grooves, and corresponding grooves or protrusions are located in the mold, the existing nozzles cannot easily spray the release agent into the grooves or under the protrusions of the mold. This leads to damage to the tenons, mortises, and joint grooves of the lightweight wall panels during demolding, resulting in incomplete structures. It also increases the workload of subsequent mold cleaning. Utility Model Content
[0004] The present invention aims to provide a spraying device for demolding lightweight wall panels, which can improve the integrity of the release agent coverage in the mold.
[0005] This utility model provides the following basic solution:
[0006] A spraying device for demolding lightweight wall panels includes a moving channel for the mold to pass through, a first lifting assembly installed on the top of the moving channel, a mounting plate connected to the free end of the first lifting assembly, the length direction of the mounting plate being perpendicular to the length direction of the moving channel, and a rotating nozzle installed on the mounting plate.
[0007] Furthermore, the mounting plate has multiple mounting holes for mounting the rotating nozzles, and these mounting holes are evenly distributed along the length of the mounting plate.
[0008] Furthermore, the rotary nozzle includes a connecting part and a nozzle head for spraying release agent. The connecting part connects to a pipe that passes through a mounting hole and is connected to a mounting plate.
[0009] Furthermore, the first lifting assembly includes two lifting brackets, which are installed on the top of the moving channel, and the free ends of the two lifting brackets are respectively connected to the two ends of the mounting plate.
[0010] Furthermore, there are multiple sets of first lifting components, which are evenly distributed along the length of the moving channel, and each free end of the first lifting component is connected to a mounting plate.
[0011] Furthermore, protective plates are provided at the openings of the moving channels. The protective plates are evenly distributed and their distribution direction is perpendicular to the length direction of the moving channels.
[0012] Furthermore, the protective sheet includes a first protective sheet and a second protective sheet. The first protective sheet is located above the mold, and the second protective sheet is located on both sides of the mold. The length of the first protective sheet is shorter than the length of the second protective sheet.
[0013] Furthermore, a second lifting assembly is installed at the top of the moving channel. The first and second lifting assemblies are arranged sequentially along the mold moving direction, and a blower facing the mold is installed at the free end of the second lifting assembly.
[0014] The beneficial effects of the basic scheme:
[0015] 1. In this solution, a first lifting assembly is installed. When the mold moves below the rotating nozzle, the first lifting assembly is controlled to lower the rotating nozzle, spraying release agent during the descent. As the rotating nozzle descends, it aligns with the grooves or protrusions within the mold. At this point, the sprayed release agent can reach the grooves and below the protrusions, effectively covering the surface of the mold. Furthermore, this solution uses a rotating nozzle for spraying. If any nozzle malfunctions, the others can still spray normally, ensuring continued coverage of the mold's inner surface with release agent. This solution, through the first lifting assembly and the rotating nozzle, effectively covers the inner surface of the mold with release agent, improving the completeness of the release agent coverage within the mold.
[0016] 2. During the spraying process, the atomized release agent may escape from the moving channel through the openings at both ends, polluting the production environment of the lightweight wall panel. This solution incorporates protective plates to block the escape of the release agent, reducing pollution to the production environment. Furthermore, the protective plates are designed with varying lengths to provide protection without interfering with the movement of the mold.
[0017] 3. In this solution, after spraying the release agent, a blower is installed to blow air into the mold. First, the air force makes the release agent flow in the mold and distribute it more evenly, further improving the integrity of the release agent coverage in the mold. Second, the airflow pre-dries the release agent in the mold, shortening the subsequent drying time of the release agent. Attached Figure Description

[0023] Example 1
[0024] A spraying device for demolding lightweight wall panels, as shown in the attached image. Figure 1 As shown, a moving channel 1 is included for the passage of the mold 2. The existing lightweight wall panel production is automated, with the mold 2 automatically moved to a designated position for processing via tracks and a shuttle vehicle. The moving channel 1 is positioned along the movement trajectory of the mold 2, and the length direction of the moving channel 1 is the direction of the movement trajectory of the mold 2.
[0025] As attached Figure 2 As shown, a first lifting assembly 3 is installed at the top of the moving channel 1, and a mounting plate 4 is connected to the free end of the first lifting assembly 3. Specifically, the first lifting assembly 3 includes two lifting brackets located within the moving channel 1 and installed at the top of the moving channel 1. The free ends of the two lifting brackets are respectively connected to both ends of the mounting plate 4. The lifting brackets can be existing electrically controlled push rods, scissor lift platforms, etc. When the lifting bracket uses an electrically controlled push rod, the base of the electrically controlled push rod is fixed to the top of the moving channel 1 with screws, so that the moving end of the electrically controlled push rod is vertically downward. The moving ends of the two electrically controlled push rods are connected to both ends of the same mounting plate 4 by screws or welding. When the lifting bracket uses a scissor lift platform, the base of the scissor lift platform is fixed to the top of the moving channel 1 with screws, so that the free end of the scissor lift platform is downward. The free ends of the two scissor lift platforms are fixedly connected to both ends of the same mounting plate 4 by screws. In this embodiment, a scissor lift platform is used as the lifting bracket.
[0026] The length of the mounting plate 4 is perpendicular to the length of the moving channel 1, and a rotating nozzle 5 is mounted on the mounting plate 4. Specifically, the mounting plate 4 has multiple mounting holes for mounting the rotating nozzle 5, which are evenly distributed along the length of the mounting plate 4, i.e., the distribution direction of the mounting holes is perpendicular to the moving direction of the mold 2. The rotating nozzle 5 includes a connecting part and a spray head for spraying release agent. The connecting part connects to a pipe 6, which passes through the mounting holes and is connected to the mounting plate 4. To accommodate molds 2 of different lengths, the mounting plate 4 has multiple mounting holes, the number of which is more than twice the number of rotating nozzles 5. Those skilled in the art can select the corresponding mounting holes to install the rotating nozzles 5 according to the actual situation. The number of rotating nozzles 5 is selected according to the length of the mold 2 and the spraying range of the rotating nozzles 5. Those skilled in the art can set it according to the actual situation. In this embodiment, the number of rotating nozzles 5 on the same mounting plate 4 is five.
[0027] The rotating nozzle 5 uses existing rotating nozzles, such as multi-outlet atomizing nozzles, square rotating micro-nozzles, 360-degree rotating micro-nozzles, four-outlet cross atomizing nozzles, and rotating multi-fork nozzles. In this embodiment, one end of the pipe 6 passes through the mounting hole and is threadedly connected to the connecting part of the rotating nozzle 5. The other end of the pipe 6 is connected to a liquid supply device (not shown in the figure), such as a water tank, which contains the release agent to be sprayed. A connector plate is provided on the pipe 6 to fix the pipe 6 in the mounting hole of the mounting plate 4. In other embodiments, a compression fitting is provided on the pipe 6 to fix the pipe 6 in the mounting hole of the mounting plate 4.
[0028] When the mold 2 moves below the rotary nozzle 5, the first lifting assembly 3 is controlled to lower the rotary nozzle 5, during which the nozzle sprays release agent. As the nozzle 5 descends, it aligns with the grooves or protrusions within the mold 2. The released agent then reaches the grooves and below the protrusions, effectively covering the surface of the mold 2. Furthermore, this design allows the rotary nozzle 5 to rotate and spray, ensuring that even if any nozzle malfunctions, the others continue to spray normally, maintaining the release agent coverage on the inner surface of the mold 2.
[0029] There are multiple sets of first lifting components 3, evenly distributed along the length of the moving channel 1. The distance between adjacent first lifting components 3 is the distance between two molds 2, and different sets of first lifting components 3 are located above different molds 2. Each free end of a first lifting component 3 is connected to a mounting plate 4, meaning there is a one-to-one correspondence between the first lifting component 3 and the mounting plate 4. In this embodiment, there are three sets of first lifting components 3, corresponding to three mounting plates 4. The rotating nozzles 5 on the three mounting plates 4 simultaneously spray release agent onto the three molds 2, improving production efficiency.
[0030] Protective plates 7 are provided at the opening of each moving channel 1. The protective plates 7 are evenly distributed and their distribution direction is perpendicular to the length direction of the moving channel 1. The protective plates 7 include a first protective plate and a second protective plate. The first protective plate is located above the mold 2, and the second protective plate is located on both sides of the mold 2. The length of the first protective plate is less than the length of the second protective plate. In this embodiment, the protective plates 7 are fixed to the opening of the moving channel 1 by screws. The length of the second protective plate is equal to the distance from the top of the moving channel 1 to the ground, and the length of the second protective plate is equal to the distance from the top of the moving channel 1 to the top of the mold 2.
[0031] During spraying, the atomized release agent may escape from the moving channel 1 through the openings at both ends, polluting the production environment of the lightweight wall panel. In this solution, protective plates 7 are installed to block the escape of the release agent, reducing pollution to the production environment. At the same time, the protective plates 7 are set with different lengths so as not to interfere with the movement of the mold 2 while providing protection.
[0032] Example 2
[0033] The difference between this embodiment and Embodiment 1 is that:
[0034] A spraying device for demolding lightweight wall panels, as shown in the attached image. Figure 3 As shown, a second lifting assembly 8 is installed on the top of the moving channel 1. In this embodiment, the second lifting assembly 8 adopts the same mechanism as the first lifting assembly 3 and is installed in the same way as the moving channel 1. The first lifting assembly 3 and the second lifting assembly 8 are arranged sequentially along the moving direction of the mold 2, that is, during the movement of the mold 2, it first passes under the first lifting assembly 3 and then under the second lifting assembly 8.
[0035] A blower 9 facing the mold 2 is installed at the free end of the second lifting assembly 8. Specifically, a mounting bracket is connected to the end of the second lifting assembly 8 away from the moving channel 1, and the blower 9 is mounted on the mounting bracket. In this embodiment, the mounting bracket and the second lifting assembly 8 are connected by screws, and the blower 9 is fixed to the mounting bracket by screws. The blower 9 can be an existing blow gun, blower, fan, etc. In this embodiment, the blower 9 is a centrifugal fan. When the mold 2 is located below the second lifting assembly 8, the blower 9 is directly facing the mold 2.
[0036] During the spraying of the release agent, the second lifting assembly 8 controls the air blower 9 to descend, causing the air blower 9 to blow air into the mold 2. This serves two purposes: first, the airflow helps the release agent flow and distribute more evenly within the mold 2, further improving the integrity of the release agent coverage; second, the airflow provides initial drying of the release agent within the mold 2, shortening the subsequent drying time. To improve production efficiency, the number of second lifting assemblies 8 is the same as the number of first lifting assemblies 3, with three molds 2 grouped together. After the release agent spraying is completed, they are simultaneously processed by the air blower 9.
