Description

Technical Field

[0001] This application relates to the field of heat insulation board production technology, specifically a turning machine for continuous production of fireproof heat insulation boards. Background Technology

[0002] In the continuous production process of fireproof and heat-insulating panels, in order to meet the requirements of double-sided composite process, such as after one side is covered with aluminum sheet, it is necessary to flip it over to process the other side. The efficiency and stability of the flipping process directly affect the overall production line capacity.

[0003] An existing patent (publication number: CN221677138U) discloses a flipping mechanism for fireproof board production, including a first support frame disposed above a base, a baffle on one side of the first support frame, and a shaft assembly between the baffle and the first support frame; a sliding groove disposed at the upper end of the base, a second support frame disposed above the base, a rotating plate on one side of the second support frame, and a motor on the other side of the second support frame; a through groove disposed inside the rotating plate, a fixing block on one side of the rotating plate, pressure plates on the inner sides of both fixing blocks, and a second electric push rod disposed between the pressure plates and the fixing blocks. The clamping mechanism of this flipping mechanism is movable and adjustable, changing the distance between the two fixing blocks, which can clamp and fix one end of fireproof boards of different sizes, making the clamping force of the fireproof board balanced, ensuring the smooth flipping of the fireproof board, and improving the use effect of the flipping mechanism.

[0004] However, the clamping mechanism of this flipping mechanism is movable and adjustable, changing the distance between the two fixed blocks. It can clamp and fix one end of fireproof boards of different sizes, so that the clamping force of the fireproof board is balanced, ensuring the smooth flipping of the fireproof board and improving the use effect of the flipping mechanism. However, the fireproof board needs to be disassembled from the fixture each time it is processed, which is not suitable for continuous production. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a turning machine for continuous production of fireproof and heat-insulating panels, which has the advantages of high turning efficiency and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a turning machine for continuous production of fireproof and heat-insulating boards, comprising a frame, two bearing seats fixedly connected to the upper surface of the middle end of the frame, a turning roller rotatably connected between the two bearing seats, a sliding groove opened inside the turning roller, a bidirectional lead screw rotatably connected between the two ends of the sliding groove, two moving blocks threadedly connected to the two ends of the bidirectional lead screw, the two moving blocks being slidably connected to the sliding groove, a turning disk being provided on the side of the two moving blocks that are close to each other, and a set of turning grooves arranged in a circle being opened on the surface of each of the two turning disks; Rollers are rotatably connected between the front and rear inner sidewalls at both ends of the frame.

[0007] Furthermore, a mounting plate is fixedly connected to one end of the flip plate, a motor is provided on one side of the mounting plate, a fixing ring is fixedly connected to the outer surface of the motor, the fixing ring is fixedly connected to the mounting plate by bolts, and the output end of the motor is fixedly connected to one end of the lead screw.

[0008] The above solution enables quick assembly and disassembly of the motor and the bidirectional lead screw. The bolt fixing method facilitates later maintenance and replacement, while ensuring that the motor output torque can be efficiently transmitted to the lead screw to avoid transmission failure. The reinforced structure of the retaining ring can prevent loosening during motor operation.

[0009] Furthermore, the flip disk is fixedly connected to its adjacent movable block by bolts.

[0010] The above solution makes the flip plate replaceable, which facilitates subsequent maintenance.

[0011] Furthermore, a fixing plate is fixedly connected to the middle of the frame, and a motor is installed on the upper surface of the fixing plate. The output end of the motor is fixedly connected to one end of the turning roller.

[0012] The above method fixes the motor in the middle of the frame and uses the coaxial connection between the motor output shaft and the turning roller to ensure the balance and stability of the turning roller when it rotates.

[0013] Furthermore, guide frames are provided at both the front and rear ends of the frame, and two sets of side columns are rotatably connected to the top of each guide frame. Each side column is located between two adjacent rollers. A bidirectional threaded rod is rotatably connected between the front and rear inner side walls of the frame. One end of the bidirectional threaded rod is fixedly connected to the output end of an external power source. The two guide frames are threadedly connected to both ends of the bidirectional threaded rod. Four limit frames arranged in a matrix are fixedly connected to the upper surface of the frame, and each guide frame is slidably connected to its adjacent limit frame.

[0014] The above solution allows for adjustment of the distance between the two guide frames, which in turn adjusts the distance between the side columns, enabling precise guidance of sheets of different widths. This prevents the sheets from shifting during transport, ensures that the center line of the sheet coincides with the center line of the flipping disc, and improves flipping accuracy.

[0015] Furthermore, the top of each of the side pillars is tapered.

[0016] The above solution guides the plate during flipping, and the conical tip guides the edge of the plate smoothly between the two sets of side posts, reducing collision and wear between the plate and the side posts, and avoiding plate jamming caused by guidance errors.

[0017] Furthermore, a limit frame is fixedly connected to the outer surface of the flipping roller, and a set of limit rods arranged in a circle are fixedly connected to the outer surface of the limit frame. The two flipping discs are slidably connected to the set of limit rods.

[0018] The above solution not only improves the stability of the two flippers when adjusting the distance, but also ensures the mechanical strength of the flippers during flipping, prevents deformation, and ensures the accuracy of the landing point. The ring structure formed by the limit rod can disperse the weight of the plate on the flippers and prevent local stress concentration.

[0019] Furthermore, two photoelectric switches are provided at the top of the frame, one photoelectric switch is located on one side of the flip groove, and the other photoelectric switch is located on one side of the adjacent side column.

[0020] With the above solution, after the board enters the flipping groove, the external control system can drive the flipping disk to rotate and flip the board. In order to avoid the photoelectric switch located on one side of the flipping groove being blocked by the surface of the flipping disk during the flipping process, another photoelectric switch is used for confirmation. That is, when the board enters the flipping groove, the board length is long and may block two photoelectric switches at the same time. At this time, the control system confirms that the board has completely entered the flipping groove before starting the flipping action, so as to avoid the flipping failure caused by the board not being fully in place.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This fireproof and heat-insulating board continuous production turning machine is linked with the conveyor through the rollers at both ends of the frame. The board can automatically slide from the conveyor through the rollers into the turning groove of the turning plate. After turning 180°, it is sent out by the roller at the other end. There is no need for manual disassembly and assembly of the board, realizing uninterrupted continuous turning and significantly improving the efficiency of the production line. The rotating roller is equipped with a bidirectional screw-driven moving block, which drives the two rotating discs to move closer or further apart synchronously, adapting to different widths of plates. At the same time, the rotating discs and the moving block are fixed with bolts, which facilitates quick replacement to meet different specifications and improves the versatility of the equipment. The guide frame adjusts the spacing through a bidirectional threaded rod, which drives the side columns to adapt to different widths of plates. Combined with the conical top design, it can guide the edge of the plate to smoothly enter between the two sets of side columns, reducing collision and wear and preventing plate jamming. It ensures that the center line of the plate coincides with the center line of the rotating disc, improving the rotation accuracy. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figures 1-5 The fireproof and heat-insulating board continuous production turning machine in this embodiment includes a frame 1. Two bearing seats 2 are fixedly connected to the upper surface of the middle end of the frame 1. A turning roller 3 is rotatably connected between the two bearing seats 2. A sliding groove 4 is opened inside the turning roller 3. A bidirectional lead screw 5 is rotatably connected between the two ends of the sliding groove 4. Two moving blocks 6 are threaded to the two ends of the bidirectional lead screw 5 respectively. The two moving blocks 6 are slidably connected to the sliding groove 4. A turning disk 7 is provided on the side of the two moving blocks 6 that is close to each other. A set of turning grooves 8 arranged in a circle is opened on the surface of the two turning disks 7.

[0026] Rollers 9 are rotatably connected between the front and rear inner walls at both ends of the frame 1. Conveyors are connected to both ends of the frame 1. The conveyors transport the external sheet material to the rollers 9 and slide it into the turning groove 8 opened in the turning plate 7, so that one end of the sheet material enters the turning groove 8. By rotating the turning plate 7, the sheet material can be turned over. After turning 180 degrees, the sheet material comes into contact with the roller 9 and the conveyor at the other end and continues to be transported, which facilitates the subsequent processing of the turned side.

[0027] One end of the rotating disk 7 is fixedly connected to the mounting plate 10. A motor 11 is provided on one side of the mounting plate 10. A fixing ring 12 is fixedly connected to the outer surface of the motor 11. The fixing ring 12 and the mounting plate 10 are fixedly connected by bolts. The output end of the motor 11 is fixedly connected to one end of the lead screw, realizing quick disassembly and assembly of the motor 11 and the bidirectional lead screw 5. The bolt fixing method facilitates later maintenance and replacement, while ensuring that the output torque of the motor 11 can be efficiently transmitted to the lead screw to avoid transmission failure. The reinforced structure of the fixing ring 12 can prevent the motor 11 from loosening when it is running. The rotating disk 7 and its adjacent moving block 6 are fixedly connected by bolts, making the rotating disk 7 replaceable and facilitating subsequent maintenance.

[0028] A fixing plate 13 is fixedly connected to the middle of the frame 1. A motor 14 is mounted on the upper surface of the fixing plate 13. The output end of the motor 14 is fixedly connected to one end of the turning roller 3. The motor 14 is fixed to the middle of the frame 1. The output shaft of the motor 14 is coaxially connected with the turning roller 3 to ensure the balance and stability of the turning roller 3 during rotation. Guide frames 15 are provided at the front and rear ends of the frame 1. Two sets of side columns 16 are rotatably connected to the top of each guide frame 15. Each side column 16 is located between two adjacent rollers 9. A bidirectional screw is rotatably connected between the front and rear inner sidewalls of the frame 1. The threaded rod 17 has one end fixedly connected to the output end of an external power source. Two guide frames 15 are threadedly connected to both ends of the threaded rod 17. Four limit frames 18 arranged in a matrix are fixedly connected to the upper surface of the frame 1. Each guide frame 15 is slidably connected to its adjacent limit frame 18, which can adjust the distance between the two guide frames 15, thereby adjusting the distance between the side columns 16. This enables precise guidance of plates of different widths, prevents the plates from shifting during the conveying process, ensures that the center line of the plate coincides with the center line of the flipping disc 7, and improves the flipping accuracy.

[0029] Each side post 16 has a tapered top, which guides the plate during flipping. The tapered top guides the edge of the plate smoothly into the space between the two sets of side posts 16, reducing collision and wear between the plate and the side posts 16, and preventing jamming due to guidance errors. A limit frame 19 is fixedly connected to the outer surface of the flipping roller 3, and a set of circumferentially arranged limit rods 20 are fixedly connected to the outer surface of the limit frame 19. The two flipping discs 7 are slidably connected to the set of limit rods 20, which not only improves the stability when adjusting the spacing between the two flipping discs 7, but also ensures the mechanical strength of the flipping discs 7 during flipping, preventing deformation and ensuring the accuracy of the landing point. The ring structure formed by the limit rods 20 can distribute the plate weight on the flipping discs 7. To prevent localized stress concentration, two photoelectric switches 21 are installed at the top of the frame 1. One photoelectric switch 21 is located on one side of the flipping groove 8, and the other photoelectric switch 21 is located on one side of the adjacent side column 16. After the board enters the flipping groove 8, the flipping disk 7 can be driven to rotate and flip the board through the external control system. In order to avoid the photoelectric switch 21 located on one side of the flipping groove 8 being blocked by the surface of the flipping disk 7 during the flipping process, the other photoelectric switch 21 is used for confirmation. That is, when the board enters the flipping groove 8, the board length may block both photoelectric switches 21 at the same time. At this time, the control system confirms that the board has completely entered the flipping groove 8 before starting the flipping action, so as to avoid the flipping error caused by the board not being fully in place.

[0030] The working principle of the above embodiment is as follows: External conveyors are connected to both ends of the frame 1. The fireproof and heat-insulating board to be flipped is conveyed by the front conveyor to the front roller 9 of the frame 1. The roller 9 reduces friction by rotating, allowing the board to slide smoothly along the length of the frame 1 until the front end of the board enters the flipping groove 8 of the flipping disc 7. Before the front end of the board enters the flipping groove 8, a photoelectric switch 21 located on one side of the flipping groove 8 is blocked. The board continues to slide until the rear end blocks another photoelectric switch 21 located on one side of the flipping groove 8. When both photoelectric switches 21 are blocked, the control system sends a signal to the motor 14. The motor 14 in the middle of the frame 1 starts, and the output shaft drives the flipping roller 3 to rotate 180° around the shaft seat 2. The flipping roller 3 drives the two flipping discs 7 and the board sandwiched in the flipping groove 8 to rotate synchronously, completing step 1. During the 80° flipping process, the ring structure formed by the limiting frame 19 and the limiting rod 20 disperses the weight of the plate, preventing deformation of the flipping disc 7 and ensuring the accuracy of the landing point. After the plate has been flipped, its rear end contacts the roller 9 at the rear end of the frame 1. Under the rotation of the roller 9, the plate continues to slide towards the rear conveyor. The rear conveyor sends the flipped plate to the next process, achieving uninterrupted continuous production. For plates of different widths, an external power source, such as a servo motor 14, drives the bidirectional threaded rod 17 to rotate. The threads at both ends of the bidirectional threaded rod 17 drive the two guide frames 15 to slide along the limiting frame 18, adjusting the spacing of the side columns 16. At the same time, the motor 11 on one side of the flipping disc 7 is fixed to the mounting plate 10 by bolts and starts, transmitting the output torque to the bidirectional lead screw 5, driving it to rotate. When the bidirectional lead screw 5 rotates, the moving blocks 6 connected by threads at both ends slide in opposite directions along the slide groove 4, causing the two flipping discs 7 to move closer or further away synchronously until the spacing of the flipping discs 7 matches the width of the plate.
