Description

Technical Field

[0001] The utility model belongs to the technical field of building material production equipment, and particularly belongs to a production line for microcrystalline heat-insulating and decorative integrated boards. Background Art

[0002] At present, the production process adopted by traditional heat-insulating and decorative integrated boards is an adhesive secondary composite process. The secondary composite process is to first prepare the required heat-insulating layer material into a finished heat-insulating board through a heat-insulating board production device. After the heat-insulating board is prepared, an organic cementitious material is used to compound the heat-insulating board and the decorative panel into an integrated board through a composite device. The bonding material used for compounding the decorative panel such as calcium silicate board and the heat-insulating board can usually only be an organic cementitious material. The organic cementitious material is prone to aging during later use, resulting in delamination and peeling of the decorative panel and the heat-insulating layer; the strength of expanded perlite used in the industry for producing expanded perlite heat-insulating boards is generally not high. During the production process, a high compression ratio method (using 2 cubic meters of expanded perlite to press into 1 cubic meter of board) is usually adopted to improve the tensile and compressive strength of the expanded perlite heat-insulating board. However, this method is prone to crushing the expanded perlite, resulting in poor water resistance, freeze-thaw resistance, and pull-out resistance of the board itself, and the board is prone to powdering later.

[0003] Therefore, the applicant has developed a microcrystalline heat-insulating and decorative integrated board, which is durable, water-resistant, freeze-thaw resistant, and aging resistant, and is also simple in construction. One-time construction can achieve the heat insulation and exterior decoration of a building; after the product is mass-produced in the factory, it is installed on-site and does not require on-site cutting, reducing the on-site cutting link, saving the construction cost and protecting the on-site construction environment; however, the production of this integrated board lacks automated equipment or production lines. Summary of the Utility Model

[0004] In view of this, the purpose of the present utility model is to overcome the deficiencies in the prior art and provide a production line for microcrystalline heat-insulating and decorative integrated boards. The present application provides the following technical solutions:

[0005] It includes a feeding hopper, a four-column press, a slurry spreading machine, a slurry scraping device, and a foaming device arranged in sequence according to workstations; a feeding platform is slidably arranged below the feeding hopper. The feeding platform is used to push the material received from the feeding hopper onto the working surface of the four-column press after receiving the material. A conveyor belt is arranged below the slurry spreading machine, the slurry scraping device, and the foaming device. A product tray is placed on the conveyor belt. The slurry spreading machine, the slurry scraping device, and the foaming device are arranged in sequence along the conveyor belt.

[0006] The materials in the feeding hopper are die-cast by a four-column press to initially form a microcrystalline heat-insulating board, which is then placed on a product tray and conveyed by a conveyor belt. During the conveying process, a slurry spreading machine spreads slurry on the microcrystalline heat-insulating board, and then a slurry scraper levels the slurry to make it uniform. Then, a bubble remover removes the bubbles on the surface of the slurry to make the surface formed after the slurry solidifies smoother and more beautiful. After the conveyor belt outputs the product tray, the product tray is uniformly left standing manually or by a manipulator. After a period of time, the slurry solidifies on the microcrystalline heat-insulating board to form a decorative layer, and finally a microcrystalline heat-insulating stone decorative integrated board is formed.

[0007] It further includes a frame, and the feeding hopper, the slurry spreading machine, the slurry scraper, the bubble remover, the feeding platform and the conveyor belt are all installed on the frame.

[0008] The four-column press includes a base. Guide columns are fixedly installed at the four corners of the top of the base. A top seat is fixedly installed at the top of the four guide columns. A hydraulic cylinder with a telescopic end facing down is arranged below the top seat. The telescopic end of the hydraulic cylinder is connected with an upper die base. A hydraulic cylinder with a telescopic end facing up is arranged above the base. The telescopic end of the hydraulic cylinder is connected with a lower die base. The upper die base and the lower die base are both slidably sleeved on the guide columns. A middle die base is further arranged between the upper die base and the lower die base. The middle die base is fixed on the guide columns. A die-casting through groove is arranged in the middle of the middle die base. An upper pressing block that fits the die-casting through groove is fixed below the upper die base. A lower top block that fits the die-casting through groove is fixed above the lower die base.

[0009] With the above settings, during die-casting, the lower top block extends into the bottom of the die-casting through groove to form a containing cavity. Then, materials are injected into the die-casting through groove, and then the upper top block descends. The extrusion between the upper top block and the lower top block die-casts the materials. After the materials are die-cast into shape, the upper top block rises and the lower top block descends, and the formed microcrystalline heat-insulating board descends with the lower top block and is removed from the die-casting through groove, which is convenient for taking the die-cast microcrystalline heat-insulating board.

[0010] The feeding platform includes a loading table located directly below the feeding hopper and a pushing plate closely attached to the upper surface of the loading table. The side of the loading table is closely attached to the middle die base and the upper surfaces are flush. A material through groove is arranged on the pushing plate. Both ends of the pushing plate are installed on linear guide rails arranged on the frame. A telescopic cylinder is installed on the frame. The telescopic end of the telescopic cylinder is connected with the pushing plate. The telescopic cylinder drives the pushing plate to reciprocate along the linear guide rails, so that the material through groove moves above the loading table and the die-casting through groove.

[0011] The feeding hopper is fixed on the frame, and a blanking device is slidably arranged at the bottom. The upper port of the blanking device is movably butted with the lower port of the feeding hopper. The lower port of the blanking device is slightly higher than the pushing plate. Both ends of the blanking device are installed on linear guide rails arranged on the frame.

[0012] With the above settings, when the feeding hopper needs to discharge materials, the materials can be discharged through the blanking device. When not working, the blanking device can be moved out from the bottom of the feeding hopper along the linear guide rails, which is convenient for inspecting and maintaining the blanking device.

[0013] A lifting frame is arranged on the frame and above the conveyor belt. A linear guide rod is screwed to the top of the lifting frame, and the linear guide rod is installed in a linear bearing screwed to the frame. A lifting frame driving structure is arranged on the frame. The working part of the lifting frame driving structure is connected to the lifting frame and is used to drive the lifting frame to lift. The slurry scraping device and the foaming device are both installed on the lifting frame.

[0014] The slurry distributing machine includes a slurry hopper. A discharge gate is arranged at the bottom of the slurry hopper. Both sides of the slurry hopper are installed on linear guide rails arranged on the frame. The linear guide rails are arranged perpendicular to the conveying direction of the conveyor belt. A left - right hand thread ball screw and a servo motor for driving the screw are also installed on the frame and are connected to the slurry hopper. The screw is arranged parallel to the linear guide rails.

[0015] The slurry scraping device includes a scraper support. A scraper clamp is screwed to the bottom of the scraper support. A serrated blade is clamped at the bottom of the scraper clamp. Both sides of the scraper support are installed on linear guide rails arranged on the lifting frame. The linear guide rails are arranged perpendicular to the conveying direction of the conveyor belt. A left - right hand thread ball screw and a servo motor for driving the screw are also installed on the lifting frame and are connected to the scraper support. The screw is arranged parallel to the linear guide rails.

[0016] The foaming device includes a foaming support. A foaming roller is installed at the bottom of the foaming support through a bearing. A plurality of bubble - pricking thorns perpendicular to the surface of the foaming roller are fixed on the foaming roller. Both sides of the foaming support are installed on linear guide rails arranged on the lifting frame. The linear guide rails are arranged perpendicular to the conveying direction of the conveyor belt. A left - right hand thread ball screw and a servo motor for driving the screw are also installed on the lifting frame and are connected to the foaming support. The screw is arranged parallel to the linear guide rails.

[0017] On both sides of the conveyor belt below the lifting frame, a centering mechanism is further provided. The centering mechanism includes a set of push plate structures oppositely arranged on both sides of the conveyor belt. The push plate structure includes a guide rail bracket fixed on the machine frame. A linear guide rail is arranged on the guide rail bracket, and a movable clamping plate is installed on the linear guide rail. The movable clamping plate is located on the side part of the conveyor belt surface. A small cylinder is installed on the machine frame at a position corresponding to the movable clamping plate, and the telescopic end of the small cylinder is connected to the movable clamping plate to drive the movable clamping plate to approach the conveyor belt.

[0018] By setting the centering structure to push and center the product tray on the conveyor belt, it is prevented that the deviation generated during the conveying process of the product tray affects the work of the slurry scraping machine and the foaming device.

[0019] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0020] An automated production line for manufacturing microcrystalline heat-insulating and decorative integrated boards is provided, which can mechanize the production of microcrystalline heat-insulating and decorative integrated boards, making up for the deficiencies of the prior art.

[0035] Please refer to Figure 1-8 As shown, a production line of a microcrystalline heat-insulating and decorative integrated board provided by the present utility model includes a feeding hopper 1, a four-column press 2, a slurry spreading machine 3, a slurry scraping device 4, and a foaming device 5 arranged in sequence according to work positions; a feeding platform 6 is slidably arranged below the feeding hopper 1. The feeding platform 6 is used for receiving the materials falling from the feeding hopper 1 and then pushing them onto the working surface of the four-column press 2. A conveyor belt 7 is arranged below the slurry spreading machine 3, the slurry scraping device 4, and the foaming device 5. A product tray 71 is placed on the conveyor belt 7. The slurry spreading machine 3, the slurry scraping device 4, and the foaming device 5 are arranged in sequence along the conveyor belt 7.

[0036] It further includes a frame 8. The feeding hopper 1, the slurry spreading machine 3, the slurry scraping device 4, the foaming device 5, the feeding platform 6, and the conveyor belt 7 are all installed on the frame 8.

[0037] The four-column press 2 includes a base 21. Guide columns 22 are fixedly installed at the four corners of the top end of the base 21. A top seat 23 is fixedly installed at the top ends of the four guide columns 22. A hydraulic cylinder with a telescopic end facing downwards is arranged below the top seat 23. An upper die holder 24 is connected to the telescopic end of the hydraulic cylinder. A hydraulic cylinder with a telescopic end facing upwards is arranged above the base 21. A lower die holder 25 is connected to the telescopic end of the hydraulic cylinder. Both the upper die holder 24 and the lower die holder 25 are slidably sleeved on the guide columns 22. A middle die holder 26 is further arranged between the upper die holder 24 and the lower die holder 25. The middle die holder 26 is fixed on the guide columns 22. A die-casting through groove 261 is arranged in the middle of the middle die holder 26. An upper pressing block 241 that fits the die-casting through groove 261 is fixed below the upper die holder 24. A lower ejecting block 251 that fits the die-casting through groove 261 is fixed above the lower die holder 25.

[0038] Among them, the hydraulic cylinder on the top seat 23 plays a main role during die-casting and is the main oil cylinder. The hydraulic cylinder on the base 21 is mainly used for unloading. Compared with the function of the ejecting cylinder in the prior art, but different from the prior art, in the prior art, the ejecting cylinder extends to eject the materials from the mold, while in this solution, the hydraulic cylinder on the base 21 relies on contraction to move the product out from below the die-casting through groove 261.

[0039] The feeding platform 6 includes a loading table 61 located directly below the feeding hopper 1 and a pusher plate 62 closely attached to the upper surface of the loading table 61. The side of the loading table 61 is closely attached to the middle die holder 26 and the upper surfaces are flush. A material through groove 621 is provided on the pusher plate 62. Both ends of the pusher plate 62 are installed on linear guide rails provided on the frame 8. A telescopic cylinder 63 is installed on the frame 8, and the telescopic end of the telescopic cylinder 63 is connected to the side of the pusher plate 62 away from the middle die holder 26. The telescopic cylinder 63 drives the pusher plate 62 to reciprocate along the linear guide rail, so that the material through groove 621 moves above the loading table 61 and the die casting through groove 261.

[0040] Among them, to ensure that the upper surfaces of the loading table 61 and the middle die holder 26 are flush, the loading table 61 can be integrally formed with the middle die holder 26 as an extended part of the middle die holder to the outside, or the loading table 61 is fixedly installed on the frame. An integral plate is arranged on the surfaces of the loading table 61 and the middle die holder 26, or when the loading table 61 is installed on the frame, a leveling tool is used to measure that its upper surface is flush with the upper surface of the middle die holder and then it is fixed.

[0041] The feeding hopper 1 is fixed on the frame 8, and a blanking device 11 is slidably arranged at the bottom. The upper port of the blanking device 11 is movably docked with the lower port of the feeding hopper 1. The lower port of the blanking device 11 is slightly higher than the pusher plate 62. Both ends of the blanking device 11 are installed on linear guide rails provided on the frame 8.

[0042] Among them, the blanking device 11 includes a housing. Multiple feeding shafts are installed in the housing by bearings. Multiple feeding blades are fixed on the feeding shafts. The bearings are located on the housing wall. The feeding shafts pass through the bearings and are fixedly installed with driven gears outside the housing. A motor is also fixedly bolted outside the housing. A driving gear is installed on the main shaft of the motor. The driving gear and the driven gear are connected by a toothed belt or a chain. The motor drives the feeding shafts to rotate so that the material passes through the feeding shafts from the upper end of the housing and then falls from the lower end of the housing to achieve blanking. The upper port of the blanking device 11 is slightly larger than the lower port of the feeding hopper 1. When the blanking device 11 is directly below the feeding hopper 1, the lower port of the feeding hopper 1 is within the range of the upper port of the blanking device 11, and there is only a small gap between the two ports.

[0043] A lifting frame 81 is arranged on the frame 8 and above the conveyor belt 7. A linear guide rod is screwed to the top of the lifting frame 81 and installed in a linear bearing screwed to the frame 8. A lifting frame driving structure 82 is arranged on the frame 8. The working part of the lifting frame driving structure 82 is connected to the lifting frame 81 and is used to drive the lifting frame 81 to lift and lower. The slurry scraping device 4 and the foaming device 5 are both installed on the lifting frame 81.

[0044] In a feasible solution, the lifting driving structure 82 includes multiple telescopic rods. The main body of the telescopic rod is fixedly bolted to the frame 8, and the telescopic end is bolted to the lifting frame 81. When the telescopic rod expands and contracts, it drives the lifting frame 81 to lift and lower along the linear guide rail.

[0045] As Figure 7 shown, in another feasible solution, the lifting drive structure 82 includes a motor installed on the frame 8. The main shaft of the motor is connected to and drives four screw lifts through multiple transmission shafts and multiple gear steering devices. The main body of the screw lift is fixedly installed on the frame 8, and its lifting end is fixedly installed with the lifting frame 81.

[0046] The pulp distributor 3 includes a pulp hopper 31. A discharge gate 32 is provided at the bottom of the pulp hopper 31. Both sides of the pulp hopper 31 are installed on linear guide rails provided on the frame 8. The linear guide rails are arranged perpendicular to the conveying direction of the conveyor belt 7. A left-right hand double-start ball screw and a servo motor for driving the screw are also installed on the frame 8. The screw is arranged parallel to the linear guide rail.

[0047] Among them, the discharge gate 32 includes a discharge switch. The discharge switch includes an arc-shaped plate that tightly seals the discharge port of the pulp hopper 31. Connecting plates are integrally formed at both ends of the arc-shaped plate. The upper ends of the connecting plates are installed on bearings fixed on the outer side wall of the pulp hopper 31. A connecting block also extends outward from the outer side wall of the pulp hopper 31. A telescopic rod is hinged on the connecting block. The telescopic end of the telescopic rod is hinged to one side of the arc-shaped plate. When the telescopic rod expands and contracts, it pulls the arc-shaped plate to rotate around the bearing, making it away from the discharge port of the pulp hopper 31, so that the discharge port is opened, and the pulp in the pulp hopper 31 falls from the discharge port.

[0048] When laying the pulp, the rotation of the main shaft of the servo motor drives the screw to rotate. The rotation of the screw makes the slider part on the screw move linearly along the screw. The slider part is fixedly installed with the side part of the pulp hopper 31. Both sides of the pulp hopper are fixedly installed on the sliders of the linear guide rails. The rotation of the screw drives the pulp hopper 31 to slide along the linear guide rail. During the sliding process, the discharge gate 32 opens and closes, and the pulp is fed. The pulp falls into the product tray on the conveyor belt 7 below it.

[0049] The pulp scraper 4 includes a scraper support 41. A scraper clamp 42 is fixedly installed at the bottom of the scraper support 41. A serrated blade 43 is clamped at the bottom of the scraper clamp 42. Both sides of the scraper support 41 are installed on linear guide rails provided on the lifting frame 81. The linear guide rails are arranged perpendicular to the conveying direction of the conveyor belt 7. A left-right hand double-start ball screw and a servo motor for driving the screw are also installed on the lifting frame 81. The screw is arranged parallel to the linear guide rail.

[0050] When scraping the material, the main shaft of the servo motor rotates to drive the lead screw to rotate. The rotation of the lead screw causes the slider part on the lead screw to move linearly along the lead screw. The slider part is screwed to the side of the scraping bracket 41, and both sides of the scraping bracket 41 are screwed to the slider of the linear guide. The rotation of the lead screw drives the scraping bracket 41 to slide along the linear guide. After the lifting frame 81 descends, the scraping bracket 41 slides to drive the serrated blade 43 to slide, and the bottom of the serrated blade 43 scrapes the slurry on the product tray 71.

[0051] The foam generator 5 includes a foam generating bracket 51. A foam roller 52 is installed at the bottom of the foam generating bracket 51 through bearings. Multiple foam piercing thorns 53 perpendicular to the surface of the foam roller 52 are fixed on the foam roller 52. Both sides of the foam generating bracket 51 are installed on the linear guide provided on the lifting frame 81. The linear guide is arranged perpendicular to the conveying direction of the conveyor belt 7. A left-right hand thread ball screw and a servo motor for driving the ball screw are also installed on the lifting frame 81 and are connected to the foam generating bracket 51. The ball screw is arranged parallel to the linear guide.

[0052] When generating foam, the main shaft of the servo motor rotates to drive the lead screw to rotate. The rotation of the lead screw causes the slider part on the lead screw to move linearly along the lead screw. The slider part is screwed to the side of the foam generating bracket 51, and both sides of the foam generating bracket 51 are screwed to the slider of the linear guide. The rotation of the lead screw drives the foam generating bracket 51 to slide along the linear guide. After the lifting frame 81 descends, the foam generating bracket 51 slides to drive the foam roller 52 to slide, and the foam piercing thorns 53 on the foam roller 52 slide and roll over on the product tray 71 to burst the bubbles on the slurry.

[0053] On both sides of the conveyor belt 7 below the lifting frame 81, a centering mechanism 72 is also provided. The centering mechanism 72 includes a set of push plate structures arranged oppositely on both sides of the conveyor belt 7. The push plate structure includes a guide rail bracket 721 fixed to the frame 8. A linear guide is provided on the guide rail bracket 721. A movable clamping plate 722 is installed on the linear guide. The movable clamping plate 722 is located on the side of the surface of the conveyor belt 7. A small cylinder 723 is installed at the corresponding position of the frame 8 and the movable clamping plate 722. The telescopic end of the small cylinder 723 is connected to the movable clamping plate 722 to drive the movable clamping plate 722 to approach the conveyor belt 7.

[0054] When centering, the small cylinder 723 expands and contracts to drive the movable clamping plate 722 to approach the conveyor belt along the linear guide. The movable clamping plates 722 on both sides simultaneously approach the conveyor belt to push the product tray 71 to achieve centering.

[0055] In specific implementation, the prepared materials are placed into the feeding hopper 1 through a conveying pipeline or manually. The materials in the feeding hopper 1 fall into the material through-channel 621 of the pushing plate 62 and on the material loading table 61 through the blanking device 11. Then, the telescopic cylinder 63 extends to push the pushing plate 62 towards the middle die base 26. When the material through-channel 621 communicates with the die-casting through-channel 261, the materials fall into the die-casting through-channel 261 and above the lower ejector block 251. Then, the hydraulic cylinder on the top seat of the four-column press 2 extends to make the upper die base 24 together with the upper pressing block 241 descend to approach the lower ejector block 251, and die-casting is performed on the materials. After die-casting is completed, the upper die base 24 rises, and the hydraulic cylinder on the base 21 contracts to make the lower die base 25 together with the lower ejector block 251 and the formed microcrystalline heat-insulating board on the lower ejector block 251 descend and move out from below the die-casting through-channel 261. Then, a worker or a manipulator moves the microcrystalline heat-insulating board into the product tray 71, and the conveyor belt conveys the product tray 71. During the conveying process, the centering mechanism 72 performs centering adjustment on the product tray. Then, the product tray 71 sequentially passes through the slurry spreading machine 3, the scraping device 4, and the foaming device 5. The slurry spreading machine 3 spreads the slurry in the product tray 71 and on the surface of the microcrystalline heat-insulating board. The scraping device 4 scrapes and levels the slurry on its surface. The foaming device 5 pricks and removes the bubbles on the slurry. Then, the product tray 71 is uniformly placed on the bracket by a manipulator or manually and left standing. After standing for a period of time, a microcrystalline heat-insulating and decorative integrated board is formed in the product tray.

[0056] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application.
