[0001] This utility model relates to the field of fireproof board processing technology, specifically to a continuous extrusion molding device for fireproof boards. Background Technology

[0002] Fire-resistant boards are a common building material, mainly made of wood, fiberglass, and resin. They are characterized by fire resistance, high temperature resistance, moisture resistance, and corrosion resistance, and are widely used in public places, kitchens, bathrooms, basements, and other locations requiring fire protection. The processing of fire-resistant boards typically includes wood treatment, hot pressing, and drying.

[0003] The extrusion molding process involves feeding, extrusion molding, and removing the finished product, which is repeated multiple times. This reduces the extrusion efficiency of the fireproof board. Furthermore, the surface of the extrusion plate used in the extrusion molding process may be covered with dust or solid debris, which can easily cause contamination or damage to the fireproof board material during extrusion, thus reducing the quality of the fireproof board.

[0004] Therefore, this utility model provides a continuous extrusion molding device for fireproof boards. Utility Model Content

This invention, through the lifting and adjusting of the hot pressing mechanism, can alternately hot press the molding dies and fireproof board raw materials placed on the first and second conveyor belts, thereby improving the hot pressing efficiency of fireproof boards. Furthermore, the cleaning mechanism, including the collection box, side cover plate, and cleaning rod, facilitates the cleaning of dust or solid debris on the outer wall of the electrically heated pressing plate, preventing dust or solid debris from affecting the processing of fireproof boards, thus demonstrating high practicality.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a continuous extrusion molding device for fireproof boards, comprising a molding box with a fixed horizontal plate inside and a cleaning mechanism. Through slots are provided inside the top and bottom of the molding box corresponding to the upper and lower sides of the fixed horizontal plate. A first conveyor belt and a second conveyor belt are respectively installed inside the through slots at the top and bottom. The second conveyor belt is longer than the first conveyor belt. A molding die is placed on top of the first and second conveyor belts. A hot pressing mechanism is provided inside the molding box via a hydraulic cylinder.

A transmission mechanism is provided between the first and second lifting plates. The cleaning mechanism includes a collection box, a side scraper, and a cleaning rod. The electrically heated pressure plate is positioned above the first and second conveyor belts.

[0007] Furthermore, both the first and second conveyor belts include mounting frames and stainless steel chain plates. The mounting frames are symmetrically fixedly installed on the inner sides of the top and bottom through grooves. The two ends of the mounting frames correspond to the outer sides of the forming box. A photoelectric sensor is fixedly installed on the top of one side of the mounting frame, and a reflector is fixedly installed inside the outer wall of one side of the forming mold.

[0008] Furthermore, a rotating roller is rotatably mounted between the two ends of the mounting frame, and the stainless steel chain plate is disposed between the two mounting frames on the outer side of the rotating roller. A support plate is horizontally fixedly mounted in the middle of the two mounting frames, and the support plate is supported on the bottom of the upper end of the stainless steel chain plate.

[0009] Furthermore, the hydraulic cylinder is fixedly installed at the center of the top of the molding box, and limit rods are fixedly installed on the top of the first lifting plate corresponding to both sides of the hydraulic cylinder. The limit rods are symmetrically slidably installed inside the top of the molding box.

[0010] Furthermore, the fixed cross plate has symmetrically provided mounting grooves at both ends, and the transmission mechanism includes gears and racks. The gears are rotatably mounted on both sides of the top of the molding box through shafts installed inside them.

[0011] Furthermore, the first lifting plate and the second lifting plate are respectively arranged above the first conveyor belt and the second conveyor belt, corresponding to the upper and lower sides of the fixed horizontal plate.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a continuous extrusion molding device for fireproof boards. A first conveyor belt and a second conveyor belt transport the molding die and fireproof board raw material into the molding box. A hydraulic cylinder adjusts the height of the first lifting plate, which in turn lowers the top electric heating pressure plate to hot-press the fireproof board raw material. Simultaneously, the first lifting plate, through a transmission mechanism including a fixed rod, gears, and racks, adjusts the height of the second lifting plate. This allows the top and bottom electric heating pressure plates to alternately hot-press the molding die and fireproof board raw material placed on the first and second conveyor belts, thereby improving the hot-pressing efficiency of the fireproof board. Furthermore, the first and second conveyor belts move the collection box, facilitating the cleaning of dust or solid debris on the outer wall of the electric heating pressure plate using the collection box, side cover, and cleaning rods. This prevents dust or solid debris from affecting the processing of the fireproof board, making it highly practical. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a continuous extrusion molding device for fireproof boards, including a molding box 1 with a fixed horizontal plate 13 inside and a cleaning mechanism. The top and bottom of the molding box 1 have through grooves 2 corresponding to the upper and lower sides of the fixed horizontal plate 13. A first conveyor belt 3 and a second conveyor belt 4 are respectively installed inside the through grooves 2 at the top and bottom. The second conveyor belt 4 is longer than the first conveyor belt 3. A molding die 5 is placed on top of the first and second conveyor belts 3 and 4. A hot pressing mechanism 7 is installed inside the molding box 1 via a hydraulic cylinder 6. The hot pressing mechanism 7 includes a first lifting plate 8, a second lifting plate 12, and an electrically heated pressing plate 15. A transmission line is provided between the first lifting plate 8 and the second lifting plate 12. The cleaning mechanism includes a collection box 21, a side scraper 22, and a cleaning rod 23. The electric heating plate 15 is located above the first conveyor belt 3 and the second conveyor belt 4. The first lifting plate 8 can be raised and lowered by the hydraulic cylinder 6. The first lifting plate 8 can be raised and lowered by the transmission mechanism 11 to adjust the second lifting plate 12. This allows for the alternating raising and lowering of the top and bottom electric heating plate 15 to hot press the fireproof board material inside the forming mold 5 on the first conveyor belt 3 and the second conveyor belt 4, thereby improving the hot pressing efficiency of the fireproof board. It is highly practical. The cleaning mechanism can clean the dust or solid debris on both sides and the bottom of the electric heating plate 15, avoiding any impact on the hot pressing of the fireproof board.

[0024] In this embodiment, both the first conveyor belt 3 and the second conveyor belt 4 include mounting frames 19 and stainless steel chain plates 20. The mounting frames 19 are symmetrically fixedly installed on the inner sides of the top and bottom through grooves 2. The two ends of the mounting frames 19 correspond to the outer sides of the forming box 1. A photoelectric sensor 16 is fixedly installed on the top of one side of the mounting frame 19. A reflector is fixedly installed inside the outer wall of one side of the forming mold 5. A rotating roller is rotatably installed between the two ends of the mounting frames 19. The stainless steel chain plate 20 is disposed on the outer side of the rotating roller between the two mounting frames 19. The middle position of the two mounting frames 19 is horizontally fixed. A support plate 14 is installed, which is supported at the bottom of the upper end of the stainless steel chain plate 20. The rotation of the rotating roller facilitates the operation of the stainless steel chain plate 20, thereby facilitating the conveying of the forming mold 5. The support plate 14 can support the top of the stainless steel chain plate 20 and the forming mold 5, thereby improving the stability of the stainless steel chain plate 20 and the forming mold 5. The photoelectric sensor 16 can detect the reflector and position the forming mold 5, making it easy to move the forming mold 5 under the electric heating pressure plate 15, so that the forming mold 5 can be squeezed by the electric heating pressure plate 15 in the future.

[0025] In this embodiment, the hydraulic cylinder 6 is fixedly installed at the center of the top of the forming box 1. Limiting rods 9 are fixedly installed on the top of the first lifting plate 8 corresponding to both sides of the hydraulic cylinder 6. The limiting rods 9 are symmetrically slidably installed inside the top of the forming box 1. The fixed horizontal plate 13 has symmetrically opened mounting grooves at both ends. The transmission mechanism 11 includes a gear 18 and a rack 17. The gear 18 is rotatably installed on both sides of the top of the forming box 1 via a shaft installed inside it. The first lifting plate 8 and the second lifting plate 12 are respectively positioned above the first conveyor belt 3 and the second conveyor belt 4, corresponding to the upper and lower sides of the fixed horizontal plate 13. Fixing rods 10 are symmetrically fixed at the bottom of both ends of the first lifting plate 8 and the top of both ends of the second lifting plate 12. The rack 17 is fixedly installed on one side of the outer wall, and the rack 17 meshes with both sides of the gear 18. The mounting configuration includes a fixed rod 10 slidably installed inside the mounting groove, a gear 18 positioned above the mounting groove, and an electric heating plate 15 fixedly installed at the bottom of the first lifting plate 8 and the second lifting plate 12. The front and rear ends of the electric heating plate 15 are flush with the outer walls of the front and rear ends of the forming box 1. The first lifting plate 8 is adjusted by the hydraulic cylinder 6. The first lifting plate 8 can drive the second lifting plate 12 to move up and down through the transmission mechanism 11, including the fixed rod 10, rack 17, and gear 18. The first lifting plate 8 and the second lifting plate 12 can move closer or further apart, facilitating alternating hot pressing of the forming mold 5 on the first conveyor belt 3 and the second conveyor belt 4, thus improving the efficiency of the hot pressing of the fireproof board. The mounting groove can limit the movement of the fixed rod 10, thereby improving the stability of the fixed rod 10, the first lifting plate 8, and the second lifting plate 12.

[0026] In this embodiment, the collection box 21 is placed on top of the first conveyor belt 3 and the second conveyor belt 4. The side scrapers 22 are symmetrically fixed on the top two sides of the front end of the collection box 21. The cleaning rod 23 is fixedly installed between the front ends of the two side scrapers 22. The inner side of the side scraper 22 and the top wall of the cleaning rod 23 are respectively in contact with the two side walls and the bottom wall of the electric heating plate 15. The first conveyor belt 3 and the second conveyor belt 4 can drive the collection box 21 to move, so that the side scrapers 22 and the cleaning rod 23 can contact the two outer side walls and the bottom wall of the electric heating plate 15 and clean them, so as to avoid the dust or solid debris on the surface of the electric heating plate 15 from affecting the processing of the fireproof board. The collection box 21 can collect the cleaned dust and solid debris.

[0027] When using this continuous extrusion molding device for fireproof boards, the molding die 5 containing the fireproof board raw material is first placed on top of the first conveyor belt 3. The first conveyor belt 3 transports the molding die 5 into the molding box 1. The photoelectric sensor 16 is electrically connected to and controlled by a computer via a cable. The photoelectric sensor 16 emits a light signal to detect the reflector on the side wall of the molding die 5. The reflected light signal is received by the photoelectric sensor 16, which then stops the first conveyor belt 3, causing the molding die 5 to move below the top electric heating plate 15. The hydraulic cylinder 6 is then activated, causing the first lifting plate 8 to descend. The first lifting plate 8 simultaneously moves the limit rod 9, the top electric heating plate 15, and the fixing rod 1. The first lifting plate 8 descends from 0, and the electric heating plate 15 is energized and heated. The limiting rod 9 can limit the first lifting plate 8, which can improve the stability of the first lifting plate 8. The electric heating plate 15 heat-presses the fireproof board material inside the forming mold 5. The fixing rod 10 drives the second lifting plate 12 to rise through the meshing action of the gear 18 and the rack 17. The second lifting plate 12 drives the bottom electric heating plate 15 to separate from the forming mold 5 on the second conveyor belt 4. The second conveyor belt 4 continues to transport other forming molds 5 and moves them to the bottom of the forming box 1, below the corresponding bottom electric heating plate 15. The photoelectric sensor 16 detects the forming mold 5. After the top fireproof board is heat-pressed, the first lifting plate 8 is driven by the hydraulic cylinder 6. As the conveyor belt rises, the top electric heating platen 15 separates from the forming mold 5 on the first conveyor belt 3. Simultaneously, the first lifting platen 8 drives the second lifting platen 12 to descend via the transmission mechanism 11. The second lifting platen 12 then uses the bottom electric heating platen 15 to hot-press the forming mold 5 on the second conveyor belt 4 and the fireproof board material inside. By alternating the lifting and lowering of the first lifting platen 8 and the second lifting platen 12, it is convenient to perform alternating hot-pressing of the fireproof board, thereby improving the processing efficiency of the fireproof board. When it is necessary to clean the outer wall of the electric heating platen 15, the collection box 21 is placed on top of the first conveyor belt 3 and the second conveyor belt 4, and the first lifting platen 8 and the top electric heating platen 15 are adjusted to the highest position. 3. The collection box 21 is moved so that the side scraper 22 and the cleaning rod 23 clean the inner walls on both sides and the bottom wall of the top electric heating plate 15, and collect dust or solid debris. After the second lifting plate 12 and the bottom electric heating plate 15 are adjusted to the top, the collection box 21 is moved by the second conveyor belt 4 so that the side scraper 22 and the cleaning rod 23 clean the inner walls on both sides and the bottom wall of the bottom electric heating plate 15, and collect dust or solid debris. This avoids dust or solid debris affecting the processing of fireproof board, and is highly practical. The front and rear ends of the electric heating plate 15 are flush with the front and rear ends of the forming box 1, which makes it convenient to manually clean the dust and solid debris on the front and rear outer walls of the electric heating plate 15.Motors are installed on one side of the rotating rollers at both ends of the first conveyor belt 3 and the second conveyor belt 4. The motors drive the first conveyor belt 3 and the second conveyor belt 4. The bottom wall of the collection box 21 and the surface of the stainless steel chain plate are both roughened to facilitate the conveying of the collection box 21. The outer wall of the forming mold 5 is made of non-reflective black.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
