The application discloses an automatic wallboard pouring system, which comprises a rack, a pouring workbench installed on the rack, a pouring pipe fixedly connected to the pouring workbench, and a support plate fixedly connected to the pouring workbench. A baffle is arranged below the support plate and located outside a pouring opening at the lower end of the pouring pipe to shield concrete splashes falling from the pouring opening. A rotating device is arranged on the support plate and driven to swing the baffle by a pushing device fixed to the rack. The baffle blocks the splashes generated during pouring to reduce the splashes splashing outside the mold. During the back-and-forth movement of the pouring workbench, the baffle is reversed to the side of the pouring pipe close to the outside of the mold to block and scrape the material behind. The position is kept stable under the action of an elastic element.

Description

Technical Field

[0001] This invention relates to the field of precast wall panel production equipment technology, specifically to an automated wall panel casting system. Background Technology

[0002] Precast wall panels are building components manufactured in a factory using concrete and steel reinforcement, then transported to the construction site for assembly. They offer advantages such as high factory production efficiency, high mechanization, reduced on-site wet work, labor savings, mitigation of seasonal influences, and shorter construction cycles. With the development of the construction industry and precast wall panel assembly technology, precast wall panels are increasingly being used in modern buildings.

[0003] In the production of precast wall panels, concrete is mixed according to the required materials to form concrete. The reinforcing steel frame for the wall panels is placed inside a wall panel forming mold. The mixed concrete is then poured into the forming mold on the production line. The mold and the concrete-filled wall panels are then transported to the next process for demolding and curing. When pouring concrete into the wall panel mold, the mold is typically placed below the concrete pouring outlet. For example, Chinese Patent Publication No. CN216609464U discloses a concrete precast component pouring machine, which shows concrete from the pouring outlet being poured into the mold below via a rotating chute. However, in such prior art devices, the concrete falls from the pouring outlet into the mold, causing splashing during the pouring process. This splashed cement slurry lands on the equipment outside the mold, causing dirt and grime on the equipment surface. Once the cement dries and hardens, it is difficult to clean, posing significant challenges to equipment maintenance. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems and provide an automated wall panel casting system.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] An automated wall panel casting system includes a frame and a casting worktable mounted on the frame. A casting pipe is fixedly connected to the casting worktable, with the lower end of the casting pipe passing through the casting worktable and suspended above the wall panel mold. A support plate is fixedly connected to the casting worktable, and a baffle is provided below the support plate. The baffle is located outside the casting port at the lower end of the casting pipe and blocks concrete splashes falling from the casting port. A rotating device mounted on the support plate, under the action of a pushing device fixed on the frame, drives the baffle to swing.

[0007] Furthermore, the rotating device includes a rotating tube rotatably connected to the support plate, with a baffle fixedly connected to the lower end of the rotating tube; a connecting rod extending along the upper surface of the support plate is fixedly connected to the upper end of the rotating tube, and a first column is fixedly connected to the end of the connecting rod away from the central axis of the rotating tube, the first column being located above the support plate; a second column is fixedly connected to the support plate, and an elastic element generating contractile elastic force is fixedly connected between the first column and the second column; a third column and a fourth column are fixedly connected to the upper surface of the support plate, the first column and the second column being located on both sides of the line connecting the third column and the fourth column; the pushing device is located on both sides of the support plate and is used to push the first column so that the first column rotates around the rotating tube and, under the tension of the elastic element, abuts the connecting rod against the side wall of the third column or the fourth column.

[0008] Furthermore, the pushing device includes a support rod fixed on the frame and a lever fixed on the support rod. The lever is located on the side of the support rod closer to the first column. When the casting workbench moves to both sides of the frame, the lever pushes the first column away from the lever.

[0009] Furthermore, the side of the actuating block that abuts against the first column is inclined and faces away from the second column.

[0010] Furthermore, the first column is located in the area between the center point of the rotating pipe and the center point of the pouring pipe, and the baffle is located on the side of the rotating pipe away from the first column.

[0011] Furthermore, the second column is located on the side of the rotating pipe away from the pouring pipe, and the third and fourth columns are located on both sides of the line connecting the rotating pipe and the second column.

[0012] Furthermore, the center line connecting the first column and the rotating tube is perpendicular to the baffle; the baffle is located above the wall panel mold, and the lower edge of the baffle is provided with a scraping slope, the lower edge of which is inclined away from the rotating tube.

[0013] Furthermore, the elastic element is a tension spring.

[0014] Furthermore, the rotating tube includes an upper tube section and a lower tube section that is slidably connected to the upper tube section, and a compression spring is provided between the upper tube section and the lower tube section.

[0015] Furthermore, the frame includes a horizontally arranged guide rod, a threaded rod parallel to the guide rod, and vertical plates fixed to both ends of the guide rod. The two ends of the threaded rod are rotatably connected to the vertical plates. A first drive motor is installed on the vertical plates. The first drive motor is connected to the threaded rod in a transmission manner, thereby driving the threaded rod to rotate. The guide rod passes through the casting worktable and guides the lateral movement of the casting worktable. The threaded rod passes through the casting worktable and is threadedly engaged with the casting worktable for transmission.

[0016] Furthermore, the bottom of the upright plate is provided with rollers, which are mounted on the workshop floor guide rail and move along the guide rail. The guide rail is arranged perpendicular to the threaded rod. A second drive motor is mounted on the upright plate. A rack is fixedly connected to one side of the guide rail. The output shaft of the second drive motor is driven by a gear. The gear meshes with the rack, causing the second drive motor to drive the frame to move along the guide rail.

[0017] Furthermore, the pouring system also includes a mixing tank for mixing concrete, the outlet of which is connected to a concrete pump. The concrete pump pumps the concrete in the mixing tank through a pipeline to the pouring pipe, and pours it from the pouring pipe into the wall panel mold.

[0018] The automated wall panel casting system provided by this invention has the following advantages: A first drive motor drives a threaded rod to rotate forward and backward, thereby driving the casting worktable to move back and forth laterally along a guide rod, thus casting concrete back and forth onto the mold; a baffle blocks the splashes generated by the concrete falling from the casting nozzle, reducing the amount of splashes outside the mold; simultaneously, during the back-and-forth movement of the casting worktable, the baffle is positioned behind the casting pipe. When the casting pipe reaches one side of the mold, a pushing device drives the baffle to swing and change direction, thereby reversing the baffle so that the casting pipe is closer to the outside of the mold. On one side, the baffle blocks the splashes from the outside of the mold; when the pouring workbench moves to one end of the frame, the actuating block contacts the first column and pushes the first column to rotate around the rotating tube. Under the tension of the elastic element, the first column causes the connecting rod to swing and move from the state of abutting against the side wall of the third column (fourth column) to the state of abutting against the side wall of the fourth column (third column), thereby driving the baffle to swing, so that the baffle is kept behind the direction of the pouring port, thereby scraping the material behind it; and under the tension of the elastic element, it maintains a stable position.

[0029] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] It should be noted that in the embodiments of the present invention, all directional indications (such as up-down-left-right-forward-backward...) are only used to explain the relative positional relationship and movement between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0032] like Figures 1-7As shown, an automated wall panel casting system is used to cast wall panels. It includes a frame 1 and a casting workbench 2 mounted on the frame 1. A casting pipe 3 is fixedly connected to the casting workbench 2, and the lower end of the casting pipe 3 passes through the casting workbench 2 and is suspended above the wall panel mold 18. A support plate 4 is fixedly connected to one side of the casting workbench 2. A baffle 5 is provided below the support plate 4. The baffle 5 is located outside the casting port at the lower end of the casting pipe 3 and blocks concrete splashes falling from the casting port. A rotating device 6 is provided on the support plate 4, which drives the baffle 5 to swing under the action of a pushing device 7 fixed on the frame 1.

[0033] In this invention, the rotating device 6 includes a rotating tube 61 rotatably connected to a support plate 4, with a baffle 5 fixedly connected to the lower end of the rotating tube 61; a connecting rod 62 extending along the upper surface of the support plate 4 is fixedly connected to the upper end of the rotating tube 61, and a first column 63 is fixedly connected to the end of the connecting rod 62 away from the central axis of the rotating tube 61, the first column 63 being located above the support plate 4; a second column 64 is fixedly connected to the support plate 4, and an elastic element 65 generating contractile elastic force is fixedly connected between the first column 63 and the second column 64; a third column 66 and a fourth column 67 are fixedly connected to the upper surface of the support plate 4, the first column 63 and the second column 64 being located on both sides of the line connecting the third column 66 and the fourth column 67; the pushing device 7 is located on both sides of the support plate 4 and is used to push the first column 63 to rotate around the rotating tube 61 so that the first column 63, under the pulling force of the elastic element 65, abuts the connecting rod 62 against the side wall of the third column 66 or the fourth column 67. The first column 63 is located in the area between the center point of the rotating pipe 61 and the center point of the pouring pipe 3. The baffle 5 is located on the side of the rotating pipe 61 away from the first column 63. The second column 64 is located on the side of the rotating pipe 61 away from the pouring pipe 3. The third column 66 and the fourth column 67 are located on both sides of the line connecting the rotating pipe 61 and the second column 64, respectively. Under the pushing action of the pushing device 7, the first column 63 disengages from the third column 66 or the fourth column 67 and rotates. During the rotation, the distance between the first column 63 and the second column 64 increases, which increases the tension of the elastic element 65. When the first column 63 passes around the center line connecting the second column 64 and the rotating tube 61 during the pushing process, the distance between the first column 63 and the second column 64 decreases. The elastic element 65 contracts and pulls the first column 63 to rotate, so that the connecting rod 62 rests on the third column 66 or the fourth column 67 on the other side of the center line connecting the second column 64 and the rotating tube 61. The connecting rod 62 drives the rotating tube 61 to rotate, thereby causing the baffle 5, which is fixedly connected to the lower end of the rotating tube 61, to rotate and swing together with the rotating tube 61 to change direction.

[0034] In this invention, the pushing device 7 includes a support rod 71 fixed to the frame 1 and a lever block 72 fixed to the support rod 71. The lever block 72 is located on the side of the support rod 71 closer to the first column 63. When the casting workbench 2 moves to both sides of the frame 1, the lever block 72 pushes the first column 63 away from the lever block 72. The side of the lever block 72 that abuts against the first column 63 is inclined and faces away from the second column 64.

[0035] In this invention, the center line connecting the first column 63 and the rotating tube 61 is perpendicular to the baffle 5; the baffle 5 is located above the wall panel mold 18, and the lower edge of the baffle 5 is provided with a scraping inclined surface 51, the lower edge of which is inclined away from the rotating tube 61. The rotating tube 61 includes an upper tube section 611 and a lower tube section 612 that is slidably connected to the upper tube section 611. A compression spring 613 is provided between the upper tube section 611 and the lower tube section 612. Specifically, to prevent rotation between the upper tube section 611 and the lower tube section 612 of the rotating tube 61, a guide post 614 is slidably connected between the upper tube section 611 and the lower tube section 612. The upper tube section 611 and the lower tube section 612 can slide up and down along the guide post 614, which is parallel to either the upper tube section 611 or the lower tube section 612. When the baffle 5 collides with an object during its movement, the compression spring 613 contracts, causing the baffle 5 to move upwards to avoid hard contact and prevent damage to the device.

[0036] In some embodiments, the elastic element 65 may be a tension spring; or it may be other elastic elements 65 that generate contractile force, such as a rubber band.

[0037] In this invention, the frame 1 includes a horizontally arranged guide rod 11, a threaded rod 12 parallel to the guide rod 11, and a vertical plate 13 fixed to both ends of the guide rod 11. The two ends of the threaded rod 12 are rotatably connected to the vertical plate 13. A first drive motor 14 is installed on the vertical plate 13. The first drive motor 14 is connected to the threaded rod 12 in a transmission manner, thereby driving the threaded rod 12 to rotate. The guide rod 11 passes through the casting worktable 2 and guides the lateral movement of the casting worktable 2. The threaded rod 12 passes through the casting worktable 2 and is threadedly engaged with the casting worktable 2 for transmission.

[0038] In this invention, the bottom of the upright plate 13 is provided with rollers 15, which are mounted on a workshop floor guide rail 16 and move along the guide rail 16. The guide rail 16 is arranged perpendicularly to the threaded rod 12. A second drive motor 17 is mounted on the upright plate 13. A rack is fixedly connected to one side of the guide rail 16. The output shaft of the second drive motor 17 is driven by a gear, which meshes with the rack, causing the second drive motor 17 to drive the frame 1 to move along the guide rail 16. By having the second drive motor 17 drive the frame 1 to move along the guide rod 11 and the first drive motor 14 drive the pouring worktable 2 to move along the threaded rod 12, movement in two mutually perpendicular directions is achieved, thereby pouring concrete into the wall panel mold 18 in both the transverse and longitudinal directions, thus facilitating complete filling of the mold.

[0039] In this invention, such as Figure 8 As shown, the pouring system also includes a mixing tank 8 for mixing concrete. The outlet of the mixing tank 8 is connected to a concrete pump 9. The concrete pump 9 pumps the concrete from the mixing tank 8 through a pipeline to the pouring pipe 3, and then pours it from the pouring pipe 3 into the wall panel mold 18. Materials are batched, mixed into concrete, and placed in the mixing tank 8. The concrete pump 9 then transports the material to the pouring pipe 3 for pouring into the wall panel mold 18. The wall panel mold 18 is placed on a conveyor belt. After pouring, the wall panel mold 18 is conveyed to the next station for preliminary solidification, followed by demolding and curing to produce the finished product. During the production process, the first and second drive motors are controlled by PLC programming to achieve automatic pouring of the wall panel mold.

[0040] During operation, the first drive motor 14 drives the threaded rod 12 to rotate forward and backward, driving the pouring worktable 2 to move back and forth laterally along the guide rod 11, thereby pouring concrete back and forth onto the mold. The baffle 5 blocks the splashes generated by the concrete falling from the pouring nozzle, reducing the amount of splashes that fly outside the mold. Simultaneously, during the back-and-forth movement of the pouring worktable 2, the baffle 5 is positioned behind the pouring pipe 3. When the pouring pipe 3 pours to one side of the mold, the pushing device 7 drives the baffle 5 to swing and change direction, causing the baffle 5 to move to the side of the pouring pipe 3 closer to the outside of the mold, thus blocking splashes from the outside of the mold. The pouring worktable 2 then moves to the frame 1. At one end, the actuating block 72 contacts the first column 63 and pushes the first column 63 to rotate around the rotating tube 61. Under the pulling force of the elastic element 65, the first column 63 causes the connecting rod 62 to swing and move from the state of abutting against the side wall of the third column 66 to the state of abutting against the side wall of the fourth column 67, or the connecting rod 62 moves from the state of abutting against the side wall of the fourth column 67 to the state of abutting against the side wall of the third column 66, thereby driving the baffle 5 to swing, so that the baffle 5 is kept behind the direction of movement of the pouring port, thereby scraping the material behind; and maintaining a stable position under the pulling force of the elastic element 65.

[0041] The parts not covered in this technical solution can be implemented using existing technologies.

[0042] The foregoing has shown and described the basic principles, main features, and characteristics of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
