Description

Technical Field

[0001] This utility model belongs to the field of refractory brick forming technology, specifically relating to a four-station continuous operation refractory brick forming device. Background Technology

[0002] Refractory bricks are important building materials capable of withstanding high temperatures and possessing good thermal stability and chemical resistance. They are widely used in the lining of high-temperature equipment in metallurgy, building materials, chemical industry, and power industry. Common refractory bricks include high-alumina bricks, magnesia-carbon bricks, silica bricks, and clay bricks, characterized by high refractoriness, high compressive strength, and good thermal shock resistance. The molding quality of refractory bricks directly affects their service life and performance stability under high-temperature environments; therefore, it is necessary to ensure the internal density and dimensional accuracy of the bricks during the production process.

[0003] In existing technologies, refractory bricks are typically manufactured using a single-station pressing process. The traditional process involves manually filling the mold with raw materials, initially leveling the surface using vibration or manual scraping, then pressing the bricks in a single pass, and finally manually removing and transporting the brick blanks. Because each step relies on manual labor, the overall production cycle is slow, resulting in low efficiency and making it difficult to meet the demands of large-scale, continuous production. Utility Model Content

[0004] This utility model provides a four-station continuous operation refractory brick forming device to solve the problems of slow production cycle and low production efficiency in the existing refractory brick production process mentioned in the background art.

[0005] The technical solution adopted by this utility model is: a four-station continuous operation refractory brick forming device, including a turntable, which can rotate along its vertical center line. Four mold mounting cavities are evenly distributed on the upper surface of the turntable, and brick pressing molds are installed in the mold mounting cavities. The turntable is arranged with a feeding station, a leveling station, a brick pressing station and a discharging station in sequence around its perimeter. The leveling station includes a scraper that can move up and down and back and forth. The scraper can move from one end of the mold mounting cavity to the other end, and the lower surface of the scraper has a serrated structure.

[0006] Four positioning slots are evenly distributed along the edge of the turntable. A positioning cylinder is installed on the outside of the turntable. The telescopic end of the positioning cylinder is connected to a positioning plate. When the positioning cylinder is activated, the positioning plate can be inserted into the positioning slot.

[0007] Guide plates are provided on both sides of the positioning plate to provide guidance for the positioning plate.

[0008] The feeding station is equipped with a screw conveyor. When the turntable rotates to the designated position, the discharge port of the screw conveyor is located directly above the mold mounting cavity.

[0009] The leveling station also includes a base frame, with a vertically arranged guide rod above the base frame. A lifting frame is slidably mounted on the guide rod, and a rotating wheel is rotatably mounted above the lifting frame. The axis of the rotating wheel is parallel to the horizontal plane. A rotatable gear plate is mounted in the middle of the lifting frame. One end of the gear plate extends upward and forms a strip groove in the middle. A fixed shaft is installed at a position off-center from the rotating wheel, and the fixed shaft is slidably mounted in the strip groove.

[0010] The lower part of the lifting frame is equipped with a horizontally movable rod, and the outer surface of the movable rod is provided with a rack, which meshes with the teeth on the edge of the gear plate.

[0011] One end of the scraper is fixed with a connecting rod, and the end of the connecting rod is connected to the moving rod.

[0012] The brick pressing station is a brick forming machine set on one side of the turntable. When the turntable rotates to the designated position, the hammer of the brick forming machine is located directly above the mold installation cavity.

[0013] The discharge station includes a pusher cylinder located below the turntable. A pusher plate is connected above the telescopic rod of the pusher cylinder. The pusher plate can pass through the turntable and push the formed bricks onto the surface of the turntable.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention achieves continuous operation of feeding, leveling, pressing, and discharging via a turntable, significantly improving the production efficiency of refractory bricks. Positioning grooves and cylinders ensure precise positioning and stable force distribution of the turntable during pressing. The leveling station uses a serrated scraper instead of vibration, effectively improving the density and dimensional consistency of the brick blanks and avoiding the impact of vibration on the mold and forming accuracy. The discharging station uses a pushing mechanism to automatically discharge bricks, reducing labor intensity. It boasts advantages such as simple overall structure and reliable operation, making it suitable for continuous and large-scale production of refractory bricks. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] As shown in the figure, a four-station continuous operation refractory brick forming device includes a turntable 1, which can rotate along its vertical center line. The rotation of the turntable 1 is mainly driven by a drive motor 28. Figure 2 As shown, a fixed base 31 is provided below the turntable 1. A guide rail 13 protrudes upward from the base 31. The guide rail 13 has an overall annular structure. A blind hole is provided on the lower surface of the turntable 1, and a spring 16 is installed in the blind hole. The lower end of the spring 16 is connected to a support rod 15, and the lower end of the support rod 15 is connected to a roller 14. The roller 14 is rotatably connected to the guide rail 13. The purpose of setting the spring 16 is to be compressed during the brick pressing process, so that the turntable 1 contacts the base 31. The base 31 supports the turntable 1. A drive motor 28 is installed in the middle of the base 31. The drive motor 28 can be a servo motor, which controls it to perform actions according to specific instructions (in this example, it is mainly used to drive the turntable 1 to rotate 90° each time and then stop rotating). The shaft end of the drive motor 28 extends to the center hole of the turntable 1, and a gear 29 is connected to the shaft end of the drive motor 28. The gear 29 meshes with the internal teeth 30 formed on the inner wall of the turntable 1. Both the gear 29 and the teeth are straight teeth, which can facilitate the micro-movement of the turntable 1 up and down.

[0023] Four mold mounting cavities 2 are evenly distributed on the upper surface of the turntable 1, and brick pressing molds 3 are installed in the mold mounting cavities 2.

[0024] The turntable 1 is equipped with a feeding station, a leveling station, a brick pressing station, and a discharging station arranged sequentially around its perimeter. The leveling station includes a scraper 4 that can move vertically and horizontally, moving from one end of the mold mounting cavity 2 to the other. The lower surface of the scraper 4 has a serrated structure. By sequentially arranging these feeding, leveling, brick pressing, and discharging stations around the turntable 1, continuous multi-station operation can be achieved, significantly improving brick pressing production efficiency. The scraper 4 in the leveling station can not only move vertically to accommodate material layers of different heights but also move horizontally and horizontally, effectively achieving uniform spreading and leveling of the raw material.

[0025] Specifically, the lower surface of scraper 4 is designed with a serrated structure. Compared to the traditional smooth scraper 4, the serrated scraper 4 can create micro-disturbances on the surface of the raw material during the scraping process, thereby effectively breaking up accumulated particles, filling gaps, preventing the raw material from piling up into clumps or forming air pockets, and improving the density and uniformity of the raw material. The serrated structure can also achieve slight particle rearrangement during the scraping process, which helps reduce the risk of voids in the subsequent pressing process and improves the overall density and mechanical properties of the formed bricks.

[0026] Four positioning slots 5 are evenly provided on the edge of the turntable 1. A positioning cylinder 7 is installed on the outside of the turntable 1. The telescopic end of the positioning cylinder 7 is connected to a positioning plate 6. When the positioning cylinder 7 is activated, the positioning plate 6 can be inserted into the positioning slot 5. In this example, the positioning plate 6 is arranged in the vertical direction and has a chamfer at the front end to facilitate its entry into the positioning slot 5. It is mainly used for precise positioning of the turntable 1.

[0027] The positioning plate 6 is provided with guide plates 8 on both sides, which are configured to provide guidance for the positioning plate 6. They can not only provide guidance, but also provide lateral support for the positioning plate 6, thus preventing the positioning cylinder 7 from being damaged by large shearing forces.

[0028] The feeding station is equipped with a screw conveyor 9. When the turntable 1 rotates to the designated position, the discharge port of the screw conveyor 9 is located directly above the mold mounting cavity 2, which is mainly used to transport the raw materials into the mold cavity.

[0029] The leveling station also includes a base frame 18, with a vertically arranged guide rod 19 above the base frame 18. A lifting frame 24 is slidably mounted on the guide rod 19. The lifting operation of the lifting frame 24 is achieved by a motor combined with a lead screw. A rotating wheel 27 is rotatably mounted above the lifting frame 24. The axis of the rotating wheel 27 is parallel to the horizontal plane. A rotatable gear disk 23 is mounted in the middle of the lifting frame 24. One end of the gear disk 23 extends upward and forms a strip groove 25 in the middle. A fixed shaft 26 is installed at a position off-center from the rotating wheel 27. The fixed shaft 26 is slidably disposed in the strip groove 25. In this example, the rotating wheel 27 is controlled to rotate by a motor. When the rotating wheel 27 rotates, the fixed shaft 26 can slide in the strip groove 25, thereby driving the gear disk 23 to rotate around its own rotation center, thus causing the lower end of the gear disk 23 to form an oscillating working state.

[0030] The lower part of the lifting frame 24 is equipped with a horizontally movable rod 22. The outer surface of the movable rod 22 is provided with a rack 21, which meshes with the teeth on the edge of the gear disk 23. Since the gear disk 23 swings left and right when working, it can drive the movable rod 22 to move back and forth in the horizontal direction. The movable rod 22 is radially limited by the limiting sleeve 20 installed on the lifting frame 24 to ensure that the movable rod 22 moves along its own axial direction.

[0031] One end of the scraper 4 is fixed with a connecting rod 17, and the end of the connecting rod 17 is connected to the moving rod 22. When the moving rod 22 moves back and forth, the connecting rod 17 and the scraper 4 can move back and forth, so that after entering the mold mounting cavity 2, the scraper 4 can be used to level the internal raw material.

[0032] The brick pressing station is a brick pressing and forming machine set on one side of the turntable 1. When the turntable 1 rotates to the designated position, the hammer 10 of the brick pressing and forming machine is located directly above the mold mounting cavity 2, which can press the flattened raw material to form the brick blank.

[0033] The discharge station includes a pusher cylinder 11 located below the turntable 1. A pusher plate 12 is connected above the telescopic rod of the pusher cylinder 11. The pusher plate 12 can pass through the turntable 1 and push the formed bricks onto the surface of the turntable 1. In this example, each mold mounting cavity 2 has a pusher hole 32 at its bottom, which is used by the pusher cylinder 11 to drive the pusher plate 12 into the pusher hole 32 and push out the formed bricks together with the mold. In addition, in other embodiments, the pusher plate 12 can also serve as the bottom plate of the brick pressing mold 3. In this structure, the pusher plate 12 can be raised directly to push out the brick blanks directly.

[0034] In this four-station continuous operation refractory brick forming device, the turntable 1 rotates intermittently at a set angle under the drive of the drive motor 28, and sequentially sends the mold mounting cavity 2 to the feeding station, leveling station, brick pressing station and discharging station.

[0035] When turntable 1 rotates to the feeding station, screw conveyor 9 starts and transports the raw material into mold mounting cavity 2. Then turntable 1 continues to rotate to the leveling station, scraper 4 moves down to the material layer and moves back and forth in the mold cavity to spread and level the raw material. The serrated structure on the lower surface of scraper 4 can break up particles and fill gaps during scraping, improving the density and uniformity of the material layer.

[0036] After leveling, the mold moves to the brick pressing station with the turntable 1. The hammer 10 of the brick pressing machine presses down to vertically press the raw material in the mold. After pressing, the mold moves to the discharge station, the push cylinder 11 is started, and the push plate 12 pushes the formed brick blank to the surface of the turntable 1 through the push hole 32 at the bottom of the mold, completing one work cycle.

[0037] During the rotation of turntable 1, the positioning cylinder 7 and the positioning plate 6 are inserted into the positioning groove 5 of turntable 1 to achieve precise positioning of each station, ensuring the stability and consistency of the operation process.

[0038] Through the above continuous cycle operation, this device can efficiently complete the feeding, leveling, pressing and discharging of raw materials, greatly improving the production efficiency of pressed bricks and the quality of brick blanks.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
