Description

Technical Field

[0001] The invention relates to the technical field of building material processing equipment, in particular to a continuous production line for heat-insulating color-coated plates and color-coated plates. Background Art

[0002] Thermal insulation color coated plate is a product with metal coil (such as cold-rolled plate, hot-dip galvanized plate, aluminum-coated plate, high aluminum alloy plate and stainless steel plate, etc.) as the base material, and various organic coatings or plastic films coated or laminated on the surface. Thermal insulation color coated plate is a new type of building material that combines thermal insulation, heat insulation and decorative functions. It not only improves the comfort and energy-saving effect of the building, but also has both beauty and practicality. It shows broad application prospects in industrial and civil buildings.

[0003] Publication No. CN117225653A discloses a highly efficient heat-insulating color-coated plate production device and color-coated plate. Through the coordinated use of components such as a cleaning plate, a piston plate and an air pipe, the gas stored in the gas cylinder enters the corresponding exhaust pipe and the nozzle position from the air pipe. The ejected gas cooperates with the cleaning plate to brush and further remove stubborn stains.

[0004] However, the thermal insulation effect of color-coated plates achieved only by thermal insulation coatings needs to be improved. Therefore, some core-filled and sandwich composite thermal insulation color-coated plates have appeared in the industry. The corrugated structure thermal insulation color-coated plates currently commonly used in the industrial field, although the galvanized substrate is three-dimensionally processed by the roll forming process, which effectively improves the structural strength of the plate, still have significant technical bottlenecks in the actual application system. From the perspective of manufacturing process, when the core layer is filled with foamed insulation material, the volume expansion effect of the material during the curing stage is likely to cause flatness deviation of the composite plate, resulting in difficulty in accurately controlling the surface flatness; and at the structural mechanics level, the directionally arranged corrugated shape can only enhance its bending resistance in the extension axis, resulting in significant strength differences in the plate in different stress directions. This structural anisotropy restricts its application range under complex working conditions.

[0005] Publication No. CN117961353A discloses a high-strength thermal insulation color-coated board production line. The structure improves the strength of the thermal insulation color-coated board by welding multiple connectors between the upper and lower original boards. This prevents the board surface from deforming due to the expansion of the thermal insulation material during the production process, and improves the strength during use; the upper and lower original boards and the thermal insulation layer are also not easy to separate.

[0006] However, in the production process of traditional high-strength thermal insulation color-coated panels, the stamping-assembly-fixing process cannot be completed on the same production line, and needs to be operated step by step (such as manual transfer to the welding station after stamping), resulting in process interruption and limited efficiency. The machine needs to be stopped during unloading and installing the frame, resulting in production intervals, which further restricts production efficiency. Increasing the strength of thermal insulation color-coated panels by only using multiple connectors is a complicated processing process and requires a large number of connectors, which reduces the environmental protection requirements of the product.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In the description of the present invention, it is necessary to understand that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0027] See also Figure 1 - Fig.13 The embodiment of the present invention provides a technical solution: a continuous production line for heat-insulating color-coated panels, including a stamping punch 20, wherein two groups of stamping punches 20 are arranged, and the two groups of stamping punches 20 are arranged opposite to each other up and down; and also including a stamping die 13, wherein two groups of stamping die 13 are arranged, and the two groups of stamping die 13 are arranged opposite to each other up and down, and the height of the stamping die 13 is located between the two groups of stamping punches 20, so as to realize double-station synchronous stamping, thereby realizing synchronous forming of the panels on both sides of the heat-insulating color-coated panels, wherein the stamping punch 20 moves in a horizontal direction so that the stamping punch 20 is opposite or not to the stamping die 13, the area where the stamping die 13 is located is the stamping station, and the position where the stamping punch 20 is not opposite to the stamping die 13 is the skeleton assembly station.

[0028] The continuous production line for heat-insulating color-coated panels provided in this embodiment also includes a negative pressure hole, which is arranged on the stamping punch 20. Preferably, the negative pressure hole is arranged near the edge of the stamping punch 20 to improve the adsorption effect, thereby fixing the color-coated panel body 3 at the stamping station on the stamping punch 20, so that when the stamping punch 20 moves to the skeleton assembly station, the color-coated panel body 3 is carried and released to the skeleton assembly station, which is beneficial to subsequent assembly.

[0029] The continuous production line for thermal insulation color-coated panels provided in this embodiment also includes a polyurethane foam injection component, which is arranged on one side of the frame assembly station to inject polyurethane foam into the assembly gap between the thermal insulation color-coated panel frame and the released color-coated panel body 3.

[0030] like Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig.12 and Fig.13As shown in the figure, to improve the injection effect of polyurethane foam, the continuous production line of heat-insulating and heat-preserving color-coated plates provided in this embodiment further includes a limiting component, which is arranged at the skeleton assembly station and is used to limit the color-coated plate body 3 released by the stamping punch 20 during the assembly process.

[0031] Specifically, the limiting component includes fixed frames 36 symmetrically arranged at the skeleton assembly station. The fixed frames 36 are symmetrically arranged vertically and horizontally. On both sides inside the fixed frames 36, there are accommodating grooves 21. Inside the accommodating grooves 21, there are rotatably connected abutting blocks 22. On one side of the fixed frames 36, there is a transmission structure to drive the abutting blocks 22 to rotate for abutting against the side of the color-coated plate body 3. Among them, there is a relief groove 38 on the side of the stamping punch 20, and the relief groove 38 is adapted to the abutting block 22.

[0032] Specifically, during the working process of the polyurethane foam injection part, the abutting block 22 is moved through the transmission structure to apply pressure to the released color-coated plate body 3, so as to maintain the tight connection between the color-coated plate body 3 and the heat-insulating and heat-preserving color-coated plate skeleton, improve the stability during the injection of polyurethane foam, and at this time, the stamping punch 20 can be separated from the color-coated plate body 3, so as to facilitate the rapid return of the stamping punch 20 and the re-combination with the stamping die 13, thereby further improving the production and processing efficiency and ensuring the continuous production of heat-insulating and heat-preserving color-coated plates.

[0033] As Figure 4 、 Figure 8 and Fig.13 shown, the polyurethane foam injection part includes a fixed frame 14 arranged on one side of the skeleton assembly station. A third cylinder 11 is fixed on the fixed frame 14. The telescopic end of the third cylinder 11 is installed with a polyurethane foam injection nozzle 27. The input end of the polyurethane foam injection nozzle 27 is connected with a polyurethane input pipe to inject polyurethane foam into the assembly gap between the heat-insulating and heat-preserving color-coated plate skeleton and the color-coated plate body 3 to form a formed part 7, realizing the synchronous completion of the three processes of stamping - assembly - injection in a linear production line, thereby greatly improving the production and processing efficiency. Through the filling of polyurethane foam, the internal structure stability of the formed part 7 can be improved, and the heat preservation effect of the formed part 7 can also be improved. It should be noted that after the polyurethane foam enters the surface drying inside the formed part 7, it can be unloaded. The unloaded formed part 7 needs to be maintained in a high-pressure environment for more than 12 hours to further improve the structural stability of the formed part 7.

[0034] As Fig.12 and Fig.13 shown, the transmission structure provided in this embodiment includes a rotating pipe sleeve 40. The rotating pipe sleeve 40 is rotatably installed at the telescopic end of the third cylinder 11, and the inner wall of the rotating pipe sleeve 40 is provided with a spiral groove 24. The telescopic end of the third cylinder 11 is provided with a ball 25 adapted to the spiral groove 24. The telescopic movement of the third cylinder 11 makes the ball 25 drive the rotating pipe sleeve 40 to rotate.

[0035] The transmission structure provided in this embodiment also includes a rotating shaft 37, which is rotatably connected to both sides of the fixed frame 36 and fixedly connected to the stop block 22, and is used to drive the stop block 22 to rotate. A central gear 39 is provided on the outside of the rotating sleeve 40, and a linkage member is provided on the fixed frame 14. The linkage member is used for the central gear 39 to drive the rotating shaft 37 to rotate, and to make any two adjacent rotating shafts 37 rotate in opposite directions.

[0036] Furthermore, the linkage member includes a first linkage gear symmetrically mounted on the fixed frame 14 and a second linkage gear symmetrically centered on the center gear 39, wherein the second linkage gear meshes with the first gear, wherein two rotating shafts 37 symmetrically centered on the center gear 39 are both equipped with a first driven gear, the first driven gear meshes with the second linkage gear, and the remaining two rotating shafts 37 symmetrically centered on the center gear 39 are both equipped with a second driven gear, the second driven gear meshes with the first linkage gear, so that any two adjacent rotating shafts 37 rotate in opposite directions. It should be noted that it is preferred that the rotation speeds of the first driven gear and the second driven gear are kept as consistent as possible to ensure that the rotation angles of the rotating shafts 37 are the same.

[0037] like Figure 1 - Fig.11 As shown, the continuous production line for heat-insulating color-coated panels provided in this embodiment also includes a lower frame 1 and an upper frame 2. The upper frame 2 is located above the lower frame 1. The lower frame 1 and the upper frame 2 are superimposed and fixed to each other. A connecting frame is provided between the lower frame 1 and the upper frame 2. A supporting plate 15 is installed on the connecting frame, and the upper and lower sides of the supporting plate 15 are fixedly connected to the stamping die 13 respectively.

[0038] It also includes a second movable frame 6, which has two second movable frames 6 and slides horizontally along the lower frame 1 and the upper frame 2 respectively. A hydraulic cylinder 19 is fixed on the second movable frame 6, and a mold base 23 for installing a stamping punch 20 is fixed at the telescopic end of the hydraulic cylinder 19. Preferably, a linear positioning rail slidably connected to the second movable frame 6 is provided on the lower frame 1 and the upper frame 2 to make the movement of the second movable frame 6 more stable. In addition, a position sensor is preferably provided on the linear positioning rail to locate the precise position of the second movable frame 6 to ensure the accuracy during the processing. In addition, in order to facilitate the fixation of the color-coated plate body 3, a negative pressure adsorption pump can be installed on the mold base 23, and the negative pressure adsorption pump is connected to the adsorption hole through a pipeline.

[0039] In order to improve the stability of the stamping process, the continuous production line for thermal insulation color-coated plates provided in this embodiment also includes guide columns slidably arranged at the four corners of the second movable frame 6 and springs arranged on the outside of the guide columns, wherein one end of the guide column passes through the second movable frame 6 and is provided with a limit plate to prevent the guide column from being separated from the second movable frame 6, and the other end of the guide column is fixedly connected to the die base 23 to pull the die base 23 up and down, thereby driving the stamping punch 20 to move. It should be noted that the spring is located between the second movable frame 6 and the limit plate to maintain the stability of the force on the die base 23, thereby improving the stability during stamping.

[0040] In order to realize the assembly between the color-coated plate body 3 formed after stamping and the thermal insulation color-coated plate frame, the thermal insulation color-coated plate continuous production line provided in this embodiment also includes a first movable frame 5. The first movable frame 5 is located at the frame assembly station. The first movable frame 5 is provided with two symmetrical clamping positions, and the clamping positions are used to fix the thermal insulation color-coated plate frame. The connecting line of the two clamping positions is perpendicular to the moving direction of the stamping punch 20 in the horizontal direction. Any clamping position of the first movable frame 5 can be moved to the space between the two fixed frames 36, so that the thermal insulation color-coated plate frame reaches the position of the stamping punch 20 and does not conflict with the position of the stamping die 13. The first movable frame 5 slides to alternately transport the thermal insulation color-coated plate frame, thereby avoiding affecting the equipment working efficiency due to the unloading of the formed parts 7 and the installation of the thermal insulation color-coated plate frame.

[0041] like Fig.11 As shown, a fixed abutment plate 26 is fixed to the middle section of the interior of the first movable frame 5 provided in this embodiment, and movable abutment plates 9 are slidably connected to the two ends of the interior of the first movable frame 5. Second cylinders 10 are also fixed to the two ends of the first movable frame 5. The second cylinder 10 is used to drive the movable abutment plate 9 to slide inside the first movable frame 5, so that the movable abutment plate 9 and the fixed abutment plate 26 clamp the thermal insulation color-coated plate skeleton. It should be noted that a contact sensor is installed on the fixed abutment plate 26, and contacts adapted to the contact sensor are provided on the two mold bases 23 to locate the position of the thermal insulation color-coated plate skeleton on the first movable frame 5, so that the positional relationship between the thermal insulation color-coated plate skeleton and the color-coated plate body 3 on the stamping punch 20 is adapted.

[0042] like Fig.11 As shown, in order to facilitate the movement of the first mobile frame 5, side frames 4 are symmetrically fixed on the outer side of the lower frame 1, and slide rails are provided on the two side frames 4. The first mobile frame 5 is provided with a sliding groove slidably connected to the slide rail to pull the first mobile frame 5 to move and improve the stability of the first mobile frame 5 when moving.

[0043] In addition, in order to drive the first movable frame 5 to move, a first cylinder 8 is installed between the lower frame 1 and the upper frame 2. The first cylinder 8 is used to drive the first movable frame 5 to slide between the two side frames 4, thereby controlling the position of the first movable frame 5.

[0044] To ensure that the thermal insulation color-coated board skeleton on the first moving frame 5 can be moved between two color-coated board bodies 3, the width of the side frame 4 provided in this embodiment is the same as the width of the lower layer frame 1, and the length of the first moving frame 5 is greater than 2 / 3 of the maximum distance between the two side frames 4, so as to ensure that the axial length of the first moving frame 5 always runs through the width of the lower layer frame 1, so that the thermal insulation color-coated board skeleton on the first moving frame 5 can be accurately moved between the two color-coated board bodies 3, facilitating the assembly of the color-coated board body 3 and the thermal insulation color-coated board skeleton.

[0045] As Figure 1 - Figure 5 shown, to realize the synchronous horizontal movement of the two second moving frames 6, in the thermal insulation color-coated board continuous production line provided in this embodiment, a driving assembly is provided between the lower layer frame 1 and the upper layer frame 2, and the driving assembly is used to drive the second moving frame 6 to move horizontally.

[0046] Among them, the driving assembly includes a ball screw 16 rotatably arranged inside the lower layer frame 1 and the upper layer frame 2. The ball screw 16 is threadedly connected to the second moving frame 6, and one end of the ball screw 16 extends to the outside of the lower layer frame 1 and the upper layer frame 2 and is provided with a synchronous pulley 17. A synchronous transmission belt 18 is provided between the synchronous pulleys 17. The other end of the lower layer frame 1 is fixed with a motor 12, and the motor 12 is used to drive one of the ball screws 16 to rotate.

[0047] Specifically, in use, the motor 12 is used to drive one of the ball screws 16 to rotate, and then the synchronous pulley 17 connected thereto rotates. Through the transmission between the synchronous pulley 17 and the synchronous transmission belt 18, the remaining synchronous pulleys 17 rotate synchronously, and then the other ball screws 16 rotate. Through the threaded connection between the ball screw 16 and the second moving frame 6, and in cooperation with the sliding of the second moving frame 6 with the lower layer frame 1 and the upper layer frame 2, the second moving frame 6 moves in the lower layer frame 1 and the upper layer frame 2, and further the position of the color-coated board body 3 can be controlled.

[0048] During use (during operation), the color-coated board body 3 is input between the stamping punch 20 and the stamping die 13. The hydraulic cylinder 19 is started to drive the die holder 23 to drive the stamping punch 20 to move towards the stamping die 13.
