Description

Technical Field

[0001] This utility model relates to the field of extruded insulation board production technology, specifically a film coating device for extruded insulation board production. Background Technology

[0002] Extruded polystyrene (XPS) insulation board is a rigid foam plastic board made from polystyrene resin, along with other raw materials and polymers. The mixture is heated and mixed while a catalyst is injected, then extruded and molded. It possesses moisture-proof and waterproof properties, allowing for a reduction in the thickness of the building's external envelope, thereby increasing usable indoor space. Coating XPS insulation board slows down oxidation and reduces corrosion. Coating involves applying a transparent plastic film to the surface of printed materials through hot pressing, providing protection and enhancing gloss.

[0003] Patent CN220995445U discloses a laminating device for extruded insulation boards, comprising: a conveying roller mounted on a device frame, with an electrical control cabinet on one side of the device frame; a second frame mounted above the device frame, with a U-shaped mounting frame on the inner side of the second frame, a pressure roller below the U-shaped mounting frame, a second motor on one side of the U-shaped mounting frame, and a heater inside the pressure roller; and a mounting plate mounted above the U-shaped mounting frame, with a spring between the U-shaped mounting frame and the mounting plate, and a first electric telescopic rod above the mounting plate. This laminating device's conveying mechanism has a limiting structure, ensuring smooth conveying of the extruded insulation board, allowing the film to correspond to the extruded insulation board, and thoroughly pressing the film onto the extruded insulation board. This facilitates laminating extruded insulation boards of different sizes and improves laminating efficiency.

[0004] The film coating device for extruded insulation boards mentioned in the above patent has a heating device located inside the pressure roller. The pressure roller heats and presses the film onto the surface of the extruded insulation board. During long-term use, uneven plastic residue will adhere to the surface of the pressure roller, affecting subsequent film coating work. Therefore, we need to propose a film coating device for the production of extruded insulation boards. Utility Model Content

A cleaning assembly for real-time cleaning of the extrusion assemblies is installed on the top of the fixed seat. A heater is fixedly connected to the bottom of the fixed seat, located between the two sets of extrusion assemblies.

[0007] Preferably, the extrusion assembly includes two sets of fixing grooves formed on the surface of the fixing base, and the inner cavities of the two sets of fixing bases are rotatably connected to pressure rollers.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a film coating device for the production of extruded insulation board, including a roller conveyor 1 for conveying extruded insulation board. One end of the top of the roller conveyor 1 is fixedly installed with an unwinding assembly for placing film. The unwinding assembly includes fixed plates 14 fixedly installed on both sides of the top of the roller conveyor 1. Unwinding rollers 15 are rotatably installed on the inner side of the two sets of fixed plates 14. Film rolls 16 are wound on the surface of the unwinding rollers 15.

[0022] The roller conveyor 1 is used to transport extruded insulation boards. During the transport process, one end of the film roll 16 can be pulled out and laid flat on top of the extruded insulation board for subsequent heating and laminating processes. The fixed plate 14 and the unwinding roller 15 work together to support and position the film roll 16, allowing it to be mounted on top of the roller conveyor 1.

[0023] Preferably, a support frame 2 is fixedly installed on the top of the roller conveyor 1. A fixed seat 3 is slidably connected to the inner cavity of the support frame 2. A lifting assembly for driving the fixed seat 3 to move up and down is installed on the top of the support frame 2. The lifting assembly includes a lifting cylinder 10 fixedly installed on the top of the support frame 2. A connecting frame 11 is fixedly connected to the top of the fixed seat 3. The telescopic end of the lifting cylinder 10 passes through the support frame 2 and extends to the bottom of the support frame 2 and is fixedly connected to the top of the connecting frame 11. Both sides of the bottom of the fixed seat 3 are provided with extrusion assemblies for pressing the film onto the surface of the extruded insulation board. The extrusion assembly includes two sets of fixing grooves 5 opened on the surface of the fixed seat 3. A pressure roller 6 is rotatably connected to the inner cavity of both sets of fixed seats 3. The upper and lower sides of the pressure roller 6 pass through the fixing grooves 5 and extend to the upper and lower sides of the fixed seat 3. A heater 4 is fixedly connected to the bottom of the fixed seat 3 and located between the two sets of extrusion assemblies.

[0024] The heater 4 heats the film. During the conveying of the extruded insulation board, the user can move the fixed seat 3 downward through the lifting cylinder 10, so that the pressure roller 6 presses against the top of the extruded insulation board to press the film onto the surface of the extruded insulation board. As the extruded insulation board moves, it will drive the pressure roller 6 to rotate. Its rotation can press the heated film onto the surface of the extruded insulation board, thereby achieving the coating of the extruded insulation board.

[0025] The top of the fixed base 3 is equipped with a cleaning component for real-time cleaning of the extrusion assembly. The cleaning component includes two sets of scrapers 7 that are attached to the pressure roller 6. Support seats 8 are fixedly installed at both ends of the two sets of scrapers 7. The bottom of the two sets of support seats 8 is fixedly connected to the top of the fixed base 3. A collection groove 9 is opened at the center of the top of the fixed base 3. The two sets of scrapers 7 are respectively located on both sides of the collection groove 9.

[0026] In this embodiment, the scraper 7 is installed in conjunction with the pressure roller 6. During the rotation of the pressure roller 6, the scraper 7 can scrape off the film residue on the surface of the pressure roller 6. In this embodiment, both sets of scrapers 7 are inclined towards the central collection groove 9. The scraped residue will be concentrated in the collection groove 9 under the push of subsequent residues. The user can clean the collection groove 9 periodically.

[0027] It is worth noting that the two sides of the fixed base 3 are slidably connected to the inner wall of the support frame 2 via limiting components. The limiting components include limiting blocks 12 fixedly installed on both sides of the fixed base 3. Limiting grooves 13 corresponding to the limiting blocks 12 are opened on both sides of the inner cavity of the support frame 2. The surface of the limiting blocks 12 is slidably connected to the inner wall of the limiting grooves 13. By setting the limiting components, the stability of the movement of the fixed base 3 can be improved. When the fixed base 3 moves, it will drive the limiting blocks 12 on both sides to slide in the inner cavity of the limiting grooves 13.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
