Description

Technical Field

[0001] The present application relates to the technical field of concrete prefabrication, and in particular to a release agent coating device for cement concrete prefabricated parts production. Background Art

[0002] Release agent is a functional substance between the mold and the finished product. Release agent is chemically resistant and will not dissolve when in contact with the chemical components of different resins, especially styrene and amines. Release agent is also heat and stress resistant, not easy to decompose or wear, release agent can be bonded to the mold without transferring to the processed part, and does not hinder painting or other secondary processing operations.

[0003] In the process of construction, concrete blocks are a very commonly used material. Concrete blocks include cubic concrete blocks and cylindrical concrete blocks. The concrete blocks are often made by casting and demolding concrete test molds. In order to conveniently remove the cured concrete components, before pouring, it is necessary to evenly apply the release agent to the surface of the concrete prefabricated formwork. The release agent can produce a layer of isolation film to lubricate and isolate, which can effectively reduce the adhesion between the concrete and the formwork, so that the concrete can be smoothly separated from the formwork when demolding, and keep the shape of the concrete intact and smooth.

[0004] The existing demoulding agent brushing device includes a frame, a material storage bottle is installed on the top of the frame, a material feeding mechanism is connected to the material discharging end at the bottom of the material storage bottle, a hand-push control mechanism is installed on the frame and below the material storage bottle, a mounting seat is fixed at the bottom of the frame, two brushing brackets are hingedly connected to the left and right sides of the mounting seat through a damping shaft, and a brushing roller is rotatably installed at the lower end of the brushing bracket. This structure continuously supplies demoulding agent to the brushing roller through the material storage bottle, so that the brushing roller always has suitable demoulding agent, thereby improving the brushing efficiency.

[0005] The device requires the operator to push the device through the hand-pushing control mechanism, and the brush roller contacts the template to evenly apply the release agent to the template. The output flow of the release agent can be adjusted through the flow regulating valve to keep the brush roller at a better humidity; after moving from one end of the template to the other end, the device is moved horizontally for a distance, which is roughly the axial spacing between the two brush rollers, so that one of the brush rollers moves to the uncoated area left in the gap between the two brush rollers during the first brushing, and brushes in this way until the brushing is completed. In addition, the spraying workload is large, time-consuming and labor-intensive, and the work efficiency is low. At the same time, the quality and effect of brushing vary from person to person, and uneven coating may occur, and the stability of quality cannot be guaranteed. Summary of the invention

[0006] In order to solve the above problems, the present application provides a release agent coating device for cement concrete precast parts production.

[0007] The present application provides a release agent brushing device for cement concrete prefabricated parts production, which adopts the following technical solution: A release agent brushing device for cement concrete prefabricated parts production, comprising: An annular base, wherein a cleaning through hole and a painting through hole are provided on the annular base; A turntable is located inside the annular base, and a first manipulator is arranged on the turntable. The rotation of the turntable drives the first manipulator to rotate, so that the first manipulator has a clamping station, a cleaning station, a painting station and a returning station located around the turntable, the cleaning station is located above the cleaning through hole, and the painting station is located above the painting through hole; A cleaning mechanism, disposed below the cleaning through hole, for scraping off debris on the inner wall of the mold when the first manipulator clamps the mold to the cleaning station; The brushing mechanism is arranged below the brushing through hole and is used for brushing the inner wall of the mold when the first manipulator clamps the mold to the brushing station.

[0008] By adopting the above technical solution, the release agent brushing device integrates an annular base, a turntable, a cleaning mechanism and a brushing mechanism, and realizes the automatic cleaning of the inner wall of the mold and the brushing of the release agent. The annular base is provided with a cleaning through hole and a brushing through hole, which correspond to the cleaning station and the brushing station respectively, ensuring the precise positioning of the mold at different stations. The manipulator on the turntable moves between the various stations as the turntable rotates, realizing the continuous automatic operation of clamping, cleaning, brushing and putting back the mold, improving the production efficiency and the uniformity of the release agent brushing, reducing the labor intensity, and at the same time ensuring the consistency of the brushing quality through automatic control, which helps to improve the production efficiency and finished product quality of the prefabricated parts.

[0009] Optionally, the brushing mechanism includes a second manipulator disposed next to the annular base, a movable body, and a brush strip; the movable body includes a driving motor fixed to the second manipulator, a movable head mounted on the driving motor, and a brush strip is provided on the movable head.

[0010] By adopting the above technical solution and setting the second manipulator, the movement of the movable body and the brush head is made more flexible, thereby achieving efficient painting of the inner wall of the mold.

[0011] Optionally, the movable head can be detachably mounted on the drive motor; the movable head comprises a plurality of movable pieces, each of which is in the shape of a Reuleaux triangle and has the same size, and each of which is provided with the brush strip on its periphery, and the end surface of the movable piece farthest from the drive motor is provided with the brush strip; When a plurality of movable sheets are aligned and stacked, the movable head is movably mounted on the output shaft of the driving motor, so that the output shaft of the driving motor rotates to drive the edge movement track of the movable sheet to be a square; When a plurality of the movable sheets are stacked in an interlaced manner, the movable head is fixedly mounted on the output shaft of the driving motor, so that the output shaft of the driving motor rotates to drive the edge moving track of the movable sheet to be circular.

[0012] Although it is convenient to use a general brush roller to paint a flat surface, there will be dead corners when painting a circular bottom surface, and it is not convenient to apply a release agent to the side wall of a cylindrical mold. By adopting the above technical solution, the driving motor in the movable body cooperates with the movable head, so that the movable head can be adaptively adjusted according to the specific shape of the mold (square or round), thereby ensuring that the release agent can be evenly and accurately coated on the inner wall of the mold. This not only improves the flexibility and adaptability of the brushing device, but also improves the brushing efficiency of the release agent, ensures the consistency of the brushing quality, reduces the uncertainty and labor intensity of manual operation, and also reduces material waste.

[0013] Optionally, the structure of the cleaning mechanism is consistent with that of the movable body, and the outer triangle formed by the movable sheet of the brushing mechanism and the brush strip is consistent in shape and size with the outer triangle of the movable sheet of the cleaning mechanism.

[0014] By adopting the above technical solution, due to the similarity between the cleaning mechanism and the movable body structure, the process from cleaning to painting can be completed without complex structural changes, which not only improves the production efficiency of the painting device, but also reduces the maintenance cost of the painting device.

[0015] Optionally, an arc-shaped through hole is provided on the annular base, and the extension direction of the arc-shaped through hole is consistent with the trajectory of the first manipulator, one end extends to the painting station, and the other end extends to the return station; the first manipulator is used to rotate the mold so that the opening faces downward after the painting mechanism paints the inner wall of the mold until the mold moves to the return station, and the first manipulator is used to rotate the mold so that the opening faces upward.

[0016] Using a general brush roller can easily cause uneven coating, and there is often excess release agent at the bottom of the mold, which not only causes waste of release agent, but also causes problems such as excessive release agent on the surface of the concrete test block making it difficult to mark, affecting the strength of the concrete test block. By adopting the above technical solution, the first manipulator can smoothly rotate the mold to the opening facing downward after the mold is painted, so that excess release agent can flow out, reducing material waste, and ensuring the cleanliness of the mold to prepare for subsequent processes. In addition, the first manipulator rotates the mold to the opening facing upward when the mold arrives and is put back to the workstation. This continuous action improves the smoothness and automation level of the operation, reduces manual intervention, and improves production efficiency and operational safety.

[0017] Optionally, when the first robot moves to the painting station, the first robot extends into the painting through hole so that the mold is located below the annular base, and the mold opening faces sideways, and the painting mechanism extends into the mold along a horizontal moving trajectory.

[0018] By adopting the above technical scheme, the brushing mechanism extends into the mold along a horizontal movable trajectory and effectively coats the inner wall of the mold from the side, which not only improves the accuracy and uniformity of the brushing, but also avoids the release agent from flowing downward to the brushing mechanism, thereby preventing contamination of the brushing mechanism and ensuring the cleanliness and efficiency of the brushing process.

[0019] Optionally, when a plurality of the movable sheets are aligned and stacked, after the coating mechanism coats the inner wall of the mold, the first manipulator is used to drive the mold to rotate; When a plurality of the movable sheets are stacked in an alternating manner and the brushing mechanism is brushing the inner wall of the mold, the first manipulator is used to drive the mold to rotate.

[0020] By adopting the above technical solution, when the movable sheets are aligned and stacked, when applying the release agent to the inner wall of the square mold, the first manipulator drives the mold to rotate after the application is completed, so that the release agent on the inner wall of the mold can be more uniform; and when the movable sheets are staggered and stacked, when applying the release agent to the inner wall of the circular mold, the first manipulator drives the mold to rotate during the application process, so that the release agent on the inner wall of the mold can be more uniform. The first manipulator adapts to the mold rotation requirements under different brushing mechanism configurations, ensuring the consistency of brushing quality.

[0021] Optionally, it also includes an air blowing mechanism, which is located on one side of the cleaning mechanism and is used to blow air into the mold after the cleaning mechanism scrapes the inner wall of the mold.

[0022] By adopting the above technical solution, after the cleaning mechanism scrapes away the debris on the inner wall of the mold, the blowing mechanism blows air into the mold to clean it, effectively removing the remaining debris and impurities, thereby improving the adhesion effect of the release agent and the demoulding efficiency of the mold.

[0023] Optionally, it also includes a first conveyor belt arranged beside the clamping station, which is used to receive the mold and transport the mold to the annular base.

[0024] By adopting the above technical solution, the mold can be directly received by the first manipulator from the first conveyor belt, and then smoothly transported to the annular base for subsequent cleaning and painting processes. This automated transportation method not only reduces the need for manual operation and labor intensity, but also improves the continuity and stability of production.

[0025] Optionally, it also includes a second conveyor belt arranged beside the putting back station, which is used to receive the mold and transport the mold away from the turntable.

[0026] By adopting the above technical solution, after the mold is painted, it can be placed on the second conveyor belt by the first robot and transported to the turntable to prepare for subsequent processing or storage of the mold. This process not only reduces manual intervention, reduces the risk of operating errors and mold damage, but also ensures the continuity and stability of the production process.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. The release agent brushing device integrates an annular base, a turntable, a cleaning mechanism and a brushing mechanism, realizing the automatic cleaning of the inner wall of the mold and the brushing of the release agent. The manipulator on the turntable moves between various stations as the turntable rotates, realizing the continuous automatic operation of clamping, cleaning, brushing and putting back the mold, improving the production efficiency and the uniformity of the release agent brushing, reducing the labor intensity, and ensuring the consistency of the brushing quality through automatic control, which helps to improve the production efficiency of prefabricated parts and the quality of finished products.

[0028] 2. The cooperation between the driving motor and the movable head in the movable body enables the movable head to be adaptively adjusted according to the specific shape of the mold (square or round), thereby ensuring that the release agent can be evenly and accurately coated on the inner wall of the cubic mold and the cylindrical mold.

[0040] When the mold is in the cleaning process, the mold opening faces downward, and when the mold is in the painting process, the mold is located below the annular base 1 and the opening faces sideways.

[0041] The painting mechanism 5 comprises a second manipulator 51 disposed beside the annular base 1, a movable body 52, and a brush strip 53. The movable body 52 comprises a driving motor 521 fixed to the second manipulator 51, a movable head 522 mounted on the driving motor 521, and a brush strip 53 is disposed on the movable head 522.

[0042] In this embodiment, the movable head 522 is detachably mounted on the drive motor 521. The movable head 522 includes a plurality of movable pieces, each of which is a Reuleaux triangle and has the same size, and is provided with a brush strip 53 at the periphery. The end surface of the movable piece farthest from the drive motor 521 is provided with a brush strip 53.

[0043] When a plurality of movable sheets are aligned and stacked, the movable head 522 is movably mounted on the output shaft of the driving motor 521, so that the output shaft of the driving motor 521 rotates to drive the edge movement track of the movable sheet to be a square.

[0044] When a plurality of movable sheets are stacked in an interlaced manner, the movable head 522 is fixedly mounted on the output shaft of the driving motor 521 , so that the output shaft of the driving motor 521 rotates to drive the edge movement track of the movable sheet to be circular.

[0045] Reference Figure 2 When multiple movable sheets are aligned and stacked, the middle of the output shaft of the driving motor 521 is rotatably connected to the rotating part 523, and the end is fixedly connected to the first bevel gear 524.

The end of the connecting rod 525 is located on the side of the first bevel gear 524 and is fixedly connected to the rotating part 523. The first bevel gear 524 is meshed with the second bevel gear 526. The output shaft of the driving motor 521 rotates, driving the first bevel gear 524 to rotate, thereby driving the second bevel gear 526 to rotate around the first bevel gear 524, so that the outermost circle of the movable head 522 is a square, and the inner wall of the square mold can be painted.

[0046] Reference Figure 3 When multiple movable sheets are staggered and stacked, the connecting rod 525 is fixedly connected to the output shaft of the driving motor 521. The output shaft of the driving motor 521 rotates, driving the connecting rod 525 to rotate, thereby driving the movable head 522 to rotate, so that the outermost circle of the movable head 522 is circular, and the inner wall of the circular mold can be coated.

[0047] The structure of the cleaning mechanism 4 is consistent with that of the movable body 52 , and the outer triangle formed by the movable piece of the brushing mechanism 5 and the brush strip 53 is consistent in shape and size with the outer triangle of the movable piece of the cleaning mechanism 4 .
