Description

Technical Field

[0001] This utility model relates to the field of fireproof board production technology, specifically to a large-plate extruder for producing wide-width fireproof boards. Background Technology

[0002] Fireproof boards are building decorative panels made from inorganic materials or organic-inorganic composite materials as the matrix, covered with decorative paper and a wear-resistant layer, and manufactured using high-temperature and high-pressure processes. They are widely used in interior partitions, ceilings, furniture manufacturing, and other fields. With the rapid development of industrialized construction and prefabricated decoration, the market demand for the size of fireproof boards (especially the "wide" specifications with a width ≥ 2m) has increased significantly. Wide-width fireproof boards can reduce the number of splicing seams, improve construction efficiency and decorative aesthetics, and are particularly suitable for large public buildings (such as airports and convention centers) and high-end commercial spaces.

[0003] Wide-width fireproof boards can be processed by extrusion molding. In existing extrusion molding machines, the material usually enters the die head directly after being discharged from the extruder. The material flows and diffuses in the die head. However, relying on the natural flow and diffusion of the material in the die head makes it difficult to ensure that the material is evenly distributed in the die head, which can easily lead to thickness deviation or surface bubble defects. Based on this, this application proposes a large-format extruder for the production of wide-width fireproof boards. Utility Model Content

[0023] 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.

[0024] This utility model provides an embodiment: Please refer to Figures 1-7 An extruder for producing wide-width fireproof panels is disclosed, comprising an extruder body 1. The extruder body 1 is a publicly available technology, requiring only that it stably extrudes the molten fluid of the raw material for producing wide-width fireproof panels; therefore, it will not be described in detail here. The extrusion end of the extruder body 1 is connected to an extrusion die 3 via a uniform distribution structure 2. The extrusion die 3 is adapted to the wide-width fireproof panel production process. In use, the fluid extruded from the extruder body 1 enters the uniform distribution structure 2 for uniform distribution, and then enters the extrusion die 3. This ensures uniform fluid distribution within the extrusion die 3, thereby guaranteeing the quality of the panel formation. Furthermore, the fluid experiences uniform extrusion pressure during its flow within the extrusion die 3, further ensuring the panel formation quality. The extrusion die 3 is a publicly available technology, adapted to the wide-width fireproof panel production process; therefore, it will not be described in detail here.

[0025] The uniform distribution structure 2 includes a uniform distribution box 5. One end of the uniform distribution box 5 is connected to the extrusion end of the extruder body 1 through a fluid inlet pipe 15. The fluid extruded from the extruder body 1 can enter the uniform distribution box 5 through the fluid inlet pipe 15. The other end of the uniform distribution box 5 is detachably connected to a sealing cover 14. The sealing cover 14 is provided with an extrusion groove 13 adapted to the fluid inlet end of the extrusion die 3. The uniform distribution box 5 is connected to the extrusion die 3 through the sealing cover 14. The fluid uniformly distributed in the uniform distribution box 5 can enter the extrusion die 3 through the extrusion groove 13, so that the fluid is evenly distributed in the extrusion die 3. In actual use, by replacing the sealing cover 14, the uniform distribution structure 2 can adapt to various extrusion dies 3, thereby enabling the application to adapt to large plates of various sizes and improving the adaptability of the application.

[0026] Both the walls of the distribution box 5 and the fluid inlet pipe 15 are equipped with flow channels, which are connected to form a heat-insulating flow channel 23 for fluid insulation. A circulating mold temperature controller 4 is installed on one side of the extruder body 1. One end of the heat-insulating flow channel 23 is connected to the outlet end of the circulating mold temperature controller 4 through the inlet pipe 8, and the other end of the heat-insulating flow channel 23 is connected to the return end of the circulating mold temperature controller 4 through the outlet pipe 17. The combined use of the circulating mold temperature controller 4 and the heat-insulating flow channel 23 can achieve the insulation of the fluid in the distribution box 5, preventing changes in the fluid temperature. The circulating mold temperature controller 4 is a publicly available technology, which only needs to meet the requirement of being able to drive the heat transfer medium to circulate in the heat-insulating flow channel 23 through a pump, transferring heat to the inner cavity of the distribution box 5, preventing changes in fluid temperature, and maintaining a stable fluid temperature.

[0027] A groove 24 is provided in the middle of the top of the extrusion groove 13. A vacuum suction plate 25 and a protective plate 26 adapted to the vacuum suction plate 25 are movably connected to the inner cavity of the groove 24. The air inlet end of the vacuum suction plate 25 and the protective plate 26 are both located on the side of the vacuum suction plate 25 close to the uniform distribution box 5. The vacuum suction plate 25 is connected to the sealing cover 14 through the first lifting structure 12. Under the action of the first lifting structure 12, the position of the vacuum suction plate 25 can be changed. When the vacuum suction plate 25 is tightly fitted to the bottom of the extrusion groove 13, the vacuum suction plate 25 achieves the sealing of the inner cavity of the uniform distribution box 5. A vacuum pump 7 is provided on one side of the uniform distribution box 5. The air inlet end of the vacuum pump 7 is connected to the inner cavity of the vacuum suction plate 25 through the first vacuum pipe 20. The vacuum pump 7 can remove the air in the uniform distribution box 5, so that the inner cavity of the uniform distribution box 5 is in a vacuum state, avoiding air from affecting the extrusion molding quality of the large plate. A vacuum gauge 18 is installed on one side of the uniform distribution box 5. The vacuum gauge 18 is used to detect the vacuum level inside the uniform distribution box 5 in real time. The controller of this application can determine the vacuum level of the uniform distribution box 5 based on the detection result. When the vacuum level of the uniform distribution box 5 meets the requirements, the vacuum pump 7 stops working. The first vacuum tube 20 is a telescopic structure, and its material can be selected according to requirements, which is not limited here. The end of the first vacuum tube 20 away from the vacuum pump 7 is movably connected to the sealing cover 14. A one-way valve is provided at the air inlet end of the first vacuum tube 20.

[0028] The protective plate 26 is connected to the sealing cover 14 through the second lifting structure 10. When the vacuum pump 7 stops working, the controller of this application controls the second lifting structure 10 to move the protective plate 26 down until the protective plate 26 blocks the air inlet of the vacuum suction plate 25, so as to prevent the vacuum degree in the uniform distribution box 5 from being destroyed.

[0029] The first lifting structure 12 is a publicly available technology, and it only needs to be able to achieve stable movement and precise positioning of the vacuum suction plate 25. The second lifting structure 10 is a publicly available technology, and it only needs to be able to achieve stable movement and precise positioning of the protective plate 26.

[0030] A fluid extrusion plate is movably connected to the inner cavity of the distribution box 5. Both ends of the distribution box 5 are equipped with drive structures adapted to the fluid extrusion plate. The output shaft of each drive structure is connected to a first electromagnet 34, which is adapted to the fluid extrusion plate. When the output shaft of the drive structure is in close contact with the fluid extrusion plate and the first electromagnet 34 is energized, the first electromagnet 34 and the fluid extrusion plate are magnetically attracted. Under the action of the drive structure, the fluid extrusion plate can move within the distribution box 5. When the drive structure moves the fluid extrusion plate, it extrudes the fluid entering the distribution box 5, filling it completely and achieving uniform distribution of the fluid within the distribution box 5. The drive structure is a publicly available technology; it only needs to achieve stable movement and precise positioning of the fluid extrusion plate within the distribution box 5.

[0031] There are two fluid extrusion plates, including a main plate 36 and a disassembly plate 28. The main plate 36 has a second electromagnet 31 at both its top and bottom, and the disassembly plate 28 is located at its bottom. When the main plate 36 and the disassembly plate 28 are tightly fitted together, and the second electromagnet 31 is energized, the second electromagnet 31 and the disassembly plate 28 are magnetically attracted to each other. The disassembly plate 28 and the main plate 36 are connected through the energized second electromagnet 31, and the main plate 36 and the disassembly plate 28 are in a snap-fit ​​state. A locking lever 33 is symmetrically arranged at the bottom of the main plate 36, and a corresponding slot 32 is provided at the top of the disassembly plate 28 to match the locking lever 33. The locking lever 33 and the slot 32 are used to snap the main plate 36 and the disassembly plate 28 together, improving the horizontal compressive strength of the fluid extrusion plate and facilitating its use.

[0032] The side wall of the disassembly plate 28 is provided with a third electromagnet 30. Both ends of the inner cavity of the uniform distribution box 5 are provided with slots 9 that are adapted to the fluid extrusion plate. Another disassembly plate 28 is provided at the bottom of the inner cavity of the slot 9. When the disassembly plate 28 is located at the bottom of the inner cavity of the slot 9 and the third electromagnet 30 is energized, the third electromagnet 30 and the uniform distribution box 5 are magnetically attracted to each other, which can realize the fixation of the disassembly plate 28 and the uniform distribution box 5.

[0033] A fluid extrusion plate transfer assembly is provided on the top of the distribution box 5. This assembly includes a lifting and translating structure 6 connected to the top of the distribution box 5 and a lifting plate 19 connected to the bottom of the lifting and translating structure 6. The lifting plate 19 is adapted to the slot 9. A fourth electromagnet 29 is provided at the bottom of the lifting plate 19. When the fourth electromagnet 29 is energized, it is magnetically attracted to the disassembly plate 28. The position of the fluid extrusion plate can be changed using the lifting and translating structure 6, allowing the two fluid extrusion plates to be used cyclically within the distribution box 5. The lifting and translating structure 6 is existing technology and only needs to ensure stable movement and precise positioning of the lifting plate 19 in both vertical and horizontal directions.

[0034] The air inlet of the vacuum pump 7 is connected to the bottom of the cavity of the slot 9 through the second vacuum tube 35, and an electric ball valve 21 is provided at one end of the second vacuum tube 35. The vacuum pump 7 can be used to remove the air in the slot 9 to prevent air from entering the distribution box 5 when the fluid extrusion plate is used for circulation.

[0035] As described above, when this application solution is used, the driving structure drives the fluid extrusion plate to squeeze the fluid in the uniform distribution box 5. Under the action of the extrusion pressure, the fluid can enter the extrusion die 3, which facilitates the extrusion molding of the large plate. When the fluid extrusion plate moves to below the slot 9 away from the extruder body 1, the fluid extrusion plate transfer assembly can transfer the fluid extrusion plate to the slot 9 near the extruder body 1. The fluid extrusion plate can cyclically squeeze the fluid, which facilitates the continuous extrusion of the large plate. During the transfer process, another fluid extrusion plate continues to squeeze the fluid under the action of the driving structure near the extruder body 1.

[0036] In addition, a vibrator 11 is installed at the bottom of the inner cavity of the distribution box 5. The vibration of the vibrator 11 can accelerate the uniform distribution of fluid within the distribution box 5. The vibrator 11 is a publicly available technology, and it is only necessary to satisfy the requirement of accelerating the uniform distribution of fluid within the distribution box 5 through vibration.

[0037] The first electromagnet 34, the second electromagnet 31, the third electromagnet 30 and the fourth electromagnet 29 mentioned above are all existing technologies, and their models can be selected according to requirements without restriction. The material of the fluid extrusion plate can also be selected according to requirements without restriction.

[0038] All electrical components involved in this application are existing technologies. Those skilled in the art can select appropriate models of electrical components according to their needs. No restrictions or elaborations are made here. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies are connected by wires. According to the actual situation, appropriate controllers are selected to meet control requirements. For specific connections and control sequences, please refer to the description below. The electrical connections between each electrical component are completed in the order of their operation. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0039] The present application will be further described below through an embodiment.

[0040] For ease of description, in this embodiment, the drive structures located on both sides of the distribution box 5 are respectively referred to as the first drive structure 16 and the second drive structure 27. When the large-format extruder for producing wide fireproof boards is in use, the controller of this application controls the first lifting structure 12 to work, causing the first lifting structure 12 to move the vacuum suction plate 25 until the vacuum suction plate 25 seals the extrusion groove 13. The vacuum pump 7 is then started, and the air in the distribution box 5 is drawn away through the first vacuum tube 20 and the vacuum suction plate 25 until the vacuum degree in the distribution box 5 meets the requirements. At the same time, the vacuum pump 7 stops working, and the controller controls the second lifting structure 10 to work, causing the second lifting structure to move the protective plate 26 until the bottom of the protective plate 26 is tightly attached to the bottom of the extrusion groove 13. The protective plate 26 protects the vacuum suction plate 25. At this time, the inner cavity of the distribution box 5 is protected by the protective plate 26, and the vacuum suction plate 25 can be reset under the action of the first lifting structure 12.

[0041] The extruder body 1 forces the fluid used for producing wide fireproof boards into the distribution box 5 through the fluid inlet pipe. The vibrator 11 inside the distribution box 5 vibrates, accelerating the uniform distribution of the fluid within the box. The controller determines the fluid volume in the distribution box 5 based on the extrusion rate of the extruder body 1. Once the fluid has completely filled the inner cavity of the distribution box 5, the lifting plate 19, under the action of the lifting and translating structure 6, presses against the fluid extrusion plate near the extruder body 1 until the fluid extrusion plate is located within the inner cavity of the distribution box 5. At this point, the second electromagnet 31 at the top of the fluid extrusion plate is de-energized, and the disassembly plate located at the bottom of the slot 9... The third electromagnet 30 on the side wall of 28 is energized. The disassembly plate 28 located at the bottom of the cavity of the slot 9 is fixed to the uniform distribution box 5. When the bottom of the fluid extrusion plate is tightly attached to the bottom of the cavity of the uniform distribution box 5, the protective plate 26 moves up under the action of the second lifting structure 10 until it is reset. The second electromagnet 31 at the output end of the first drive structure 16 is energized. When the first drive structure 16 pushes the fluid extrusion plate to move, the fluid extrusion plate squeezes the fluid and squeezes the fluid evenly into the extrusion die 3 through the extrusion groove 13. The fluid can be evenly distributed in the extrusion die 3, which is convenient for the extrusion molding of the large plate.

[0042] During the fluid extrusion process, the fluid extrusion plate transfer assembly moves another main plate 36 and a disassembly plate 28 connected to the top of the other main plate 36 into the slot 9 near the extruder body 1. When the bottom end of the other main plate 36 is located in the inner cavity of the slot 9, the air in the slot 9 is removed by the vacuum pump 7 and the second vacuum tube 35. When the other main plate 36 is engaged and connected with the disassembly plate 28 at the bottom of the inner cavity of the slot 9, the other main plate 36 and the disassembly plate 28 at the bottom of the inner cavity of the slot 9 form another fluid extrusion plate.

[0043] When the fluid extrusion plate, which is pressing the fluid, is about to move below another slot 9 (the position of the fluid extrusion plate here can be set according to requirements and is not limited here), the second drive structure 27 connects to the fluid extrusion plate. The second drive structure 27 drives the fluid extrusion plate to continue moving until the fluid extrusion plate moves directly below the other slot 9. During the continued movement of the fluid extrusion plate, the first drive structure 16 resets. When the fluid extrusion plate moves directly below the other slot 9, the other fluid extrusion plate is located in the inner cavity of the distribution box 5 and is connected to the first drive structure 16. When the fluid extrusion plate moves directly below the other slot 9, the second electromagnet 31 at the top of the fluid extrusion plate is in a magnetic attraction state, realizing the connection with the disassembly plate 28 at the bottom of the inner cavity of the other slot 9. The fluid extrusion plate can be removed using the fluid extrusion plate transfer assembly. During the movement of the fluid extrusion plate, the first drive structure 16 drives the other fluid extrusion plate to continue pressing the fluid, which facilitates the continuous extrusion molding of large plates.

The specific connection methods of each structure adopt conventional technical means such as bolt connection that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The materials of each component can be selected according to the requirements and are not limited here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
