Description

Technical Field

[0001] This utility model relates to the field of sintered magnesia brick forming technology, specifically to a mold filler leveling device for enhancing the forming of sintered magnesia bricks. Background Technology

[0002] Magnesia bricks are classified into fired magnesia bricks and unfired magnesia bricks. Fired magnesia bricks are further divided into silicate-bonded magnesia bricks, directly bonded magnesia bricks, and rebonded magnesia bricks.

[0003] During the molding process of fired magnesia bricks, raw materials are manually or quantitatively poured into the mold using a feeding machine. When poured, the material is generally higher in the center and lower around the edges, resulting in uneven distribution. This uneven distribution leads to problems with the brick blanks, especially the corners, where the density is low and the strength is poor. In severe cases, corner chipping may occur. Therefore, it is necessary to level the raw material within the mold. Currently, manual leveling is mostly used, employing a scraper to level the raw material to the same height as the mold. However, this method is inefficient, labor-intensive, and the leveling effect needs improvement. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides a mold filler leveling device for enhancing the molding of fired magnesia bricks. The device uses an electric slide rail to move a pair of second arc-shaped scrapers and a first square scraper to one side to perform a rough leveling of the raw material, and then moves in the opposite direction to perform a fine leveling using a straight scraper. This ensures that the inner edge and four corners of the mold are filled with raw material. The device features high worktable efficiency, a high degree of automation, and good leveling effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold filler leveling device for enhancing the molding of fired magnesia bricks, comprising a mold, a pair of electric slide rails, a pair of sliding bodies, a first arc-shaped scraper, a pair of second arc-shaped scrapers, a straight scraper, a drive assembly, and a sliding component. The pair of electric slide rails are fixedly arranged on the front and rear sides of the mold. The pair of sliding bodies are horizontally slidably arranged on the electric slide rails. One end of each pair of second arc-shaped scrapers is fixedly connected to the side wall of the sliding body, and the other end is connected to both ends of the first arc-shaped scraper. The concave and convex sides of the first arc-shaped scraper are opposite to those of the second arc-shaped scraper. The bottoms of the first and second arc-shaped scrapers are set at a certain distance from the upper surface of the mold. The convex sides of the pair of second arc-shaped scrapers are vertically slidably connected to the side wall of the straight scraper through the sliding component. The drive assembly is fixedly arranged on the concave side of the first arc-shaped scraper. The drive assembly can drive the straight scraper to move vertically and make the bottom of the straight scraper contact the surface of the mold.

[0006] Preferably, the drive assembly includes a motor, a threaded rod, and a moving block. The motor is fixedly connected to the concave side of the first arc-shaped scraper, the lower end of the threaded rod is fixedly connected to the output end of the motor, and the moving block is fixedly connected to the center position of the side wall of the straight scraper. The moving block has a threaded hole, which is screwed to the threaded rod.

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.

[0018] like Figure 1-3 As shown, a filler leveling device for a mold 7 used to enhance the molding of fired magnesia bricks includes a mold 7, a pair of electric slide rails 12, a pair of sliding bodies 2, a first arc-shaped scraper 5, a pair of second arc-shaped scrapers 3, a straight scraper 11, a drive assembly, and a sliding component. The pair of electric slide rails 12 are fixedly arranged on the front and rear sides of the mold 7. The pair of sliding bodies 2 are respectively horizontally slidably arranged on the electric slide rails 12. One end of the pair of second arc-shaped scrapers 3 is fixedly connected to the side wall of the sliding body 2, and the other end is respectively connected to both ends of the first arc-shaped scraper 5. The concave and convex sides of the first arc-shaped scraper 5 are opposite to those of the second arc-shaped scraper 3. The bottom of the first arc-shaped scraper 5 and the second arc-shaped scraper 3 are set at a certain distance from the upper surface of the mold 7. The convex sides of the pair of second arc-shaped scrapers 3 are vertically slidably connected to the side wall of the straight scraper 11 through the sliding component. The drive assembly is fixedly arranged... On the concave side of the first arc-shaped scraper 5, the driving assembly can drive the straight scraper 11 to move vertically and make the bottom of the straight scraper 11 contact the surface of the mold 7; the driving assembly includes a motor 8, a threaded rod 6, and a moving block 9. The motor 8 is fixedly connected to the concave side of the first arc-shaped scraper 5, the lower end of the threaded rod 6 is fixedly connected to the output end of the motor 8, and the moving block 9 is fixedly connected to the center position of the side wall of the straight scraper 11. The moving block 9 has a threaded hole, which is screwed to the threaded rod 6 through the threaded hole; the sliding component includes a slider 4 and a slide groove 10. The slide groove 10 is vertically opened on the side wall of the straight scraper 11, and the slider 4 is fixedly set on the convex side of the second arc-shaped scraper 3. The slider 4 is slidably connected to the slide groove 10; the first arc-shaped scraper 5 and the second arc-shaped scraper 3 are bolted together; limit plates 1 are provided on both sides of the electric slide rail 12.

[0019] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:

[0020] According to the instruction manual Figure 1-3 It can be seen that when this utility model is working, the drive component drives the straight scraper 11 to move vertically so that its bottom is higher than or level with the bottom of the first arc-shaped scraper 5 and the second arc-shaped scraper 3. Initially, the first arc-shaped scraper 5, the second arc-shaped scraper 3, and the straight scraper 11 are located outside the mold 7, and the material is fed manually or by an injection machine. Figure 1Taking the design direction as an example, firstly, the electric slide rail 12 drives the slide body 2, the second arc-shaped scraper 3, the first arc-shaped scraper 5, and the straight scraper 11 to move to the left to flatten the raw material. However, since the bottoms of the first arc-shaped scraper 5 and the second arc-shaped scraper 3 are set at a certain distance from the upper surface of the mold 7, this distance can be determined according to the size of the mold 7 and the working experience of the technicians. Therefore, when flattening, the raw material may not be parallel to the surface of the mold 7, and there may be cases where the right edge or corner is not fully filled. This flattening is called rough flattening. However, since the convex side of the first arc-shaped scraper 5 faces the raw material, it can reverse the flow of the raw material in the middle to both sides, that is, allow the raw material to fill the edge. The concave side of the second arc-shaped scraper 3 faces forward, gathering the raw material to ensure the filling effect of the edge. After the first arc-shaped scraper 5, the second arc-shaped scraper 3, and the straight scraper 11 move to the leftmost end, the straight scraper 11 moves downwards when the drive assembly works, so that its bottom abuts against the surface of the mold 7. Then, the electric slide rail 12 works to make the straight scraper 11 flatten the raw material. After flattening, the raw material is parallel to the surface of the mold 7, and all positions are filled with raw material, resulting in fine flattening. This utility model uses the electric slide rail 12 to drive a pair of second arc-shaped scrapers 3 and first arc-shaped scrapers to move to one side to perform a rough flattening of the raw material, and then moves in the opposite direction to perform fine flattening through the straight scraper 11, ensuring that the inner edge and four corners of the mold 7 are filled with raw material. The worktable has high efficiency, a high degree of automation, and good flattening effect.

[0021] The drive assembly includes a motor 8, a threaded rod 6, and a moving block 9. The motor 8 is fixedly connected to the concave side of the first arc-shaped scraper 5. The lower end of the threaded rod 6 is fixedly connected to the output end of the motor 8. The moving block 9 is fixedly connected to the center position of the side wall of the straight scraper 11. The moving block 9 has a threaded hole, through which it is screwed onto the threaded rod 6. During operation, the output end of the motor 8 rotates, driving the threaded rod 6 to rotate. Since the moving block 9 is screwed onto the threaded rod 6 through the threaded hole, and the straight scraper 11 is vertically limited by the second arc-shaped scraper 3 through a sliding member, it can drive the straight scraper 11 to move vertically for position adjustment. The structure is simple and the drive is stable.

[0022] The sliding component includes a slider 4 and a groove 10. The groove 10 is vertically formed on the side wall of the straight scraper 11. The slider 4 is fixedly set on the convex side of the second arc-shaped scraper 3. The slider 4 is slidably connected to the groove 10 to ensure the stability of the vertical movement of the straight scraper 11.

[0023] The first arc-shaped scraper 5 and the second arc-shaped scraper 3 are connected by bolts, which can be disassembled for easy repair and maintenance.

[0024] The electric slide rail 12 is equipped with limit plates 1 on both sides to limit the movement range of the first arc-shaped scraper 5, the second arc-shaped scraper 3 and the straight scraper 11, so as to ensure the safety of the working area.

[0025] 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.
