Abstract
Description
Technical Field
[0001] This utility model relates to the field of iron oxide ball production technology, and in particular to a ball pressing machine roller gap adjustment mechanism. Background Technology
[0002] Iron oxide scale balls are byproducts produced during steel rolling, formed through crushing, screening, and pressing. They typically contain 60%-70% iron and small amounts of impurities such as CaO and SiO2. With high density and hardness, they can be used as auxiliary raw materials in steelmaking, reducing production costs. When used in converters or electric furnaces, iron oxide scale balls can replace some scrap steel or iron ore, helping to regulate the temperature and chemical composition of the molten pool, while also reducing dust pollution and achieving resource recycling.
[0003] To efficiently produce iron oxide briquettes, a briquetting machine is typically used. The specific production process is as follows: Iron oxide scale mixed with an iron oxide briquette binder is fed into the briquetting machine's hopper between two pressure rollers. Both rollers have spherical grooves. Through the compression of the two rollers, the material is pressed into a spherical shape. As can be seen, the pressure rollers are a crucial component of the briquetting machine. With prolonged use, the roller skins inevitably wear down. As a result, the rollers gradually move closer together, further accelerating the wear process. Utility Model Content

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0018] A briquetting machine roller gap adjustment mechanism includes: a shim structure 1 and a widening device 2. The shim structure 1 is placed between two adjacent rollers. The shim structure 1 includes a bonding plate 11 and a support plate 12. The bonding plate 11 is bonded to one of the rollers. One end of the support plate 12 is fixedly connected to the bonding plate 11. The other end of the support plate 12 is bonded to the other roller. The support plate 12 and the bonding plate 11 form an L-shape.
[0019] Specifically, the bonding plate 11 has a clamping hole 111. The clamping hole 111 corresponds to the sliding track of the pressure roller. When the bonding plate 11 is in contact with the pressure roller, the inner wall of the clamping hole 111 is in contact with the sliding track. There are two bonding plates 11. There are also two support plates 12. The gasket structure 1 also includes a hinge plate 13. The hinge plate 13 is disposed between the support plates 12. One side of the hinge plate 13 is connected to one of the support plates 12, and the other side is connected to the other support plate 12, allowing the support plates 12 to swing relative to each other.
[0020] In practical applications, the two bonding plates 11 are separated from each other. Under the action of the hinge plate 13, the two support plates 12 can swing relative to each other around the hinge plate 13, allowing the two bonding plates 11 to move closer or further apart. The gasket structure 1 is placed in the gap between the two pressure rollers, and the two bonding plates 11 are moved further apart by swinging the support plate 12. The position of the gasket structure 1 is adjusted so that the two bonding plates 11 are located on opposite sides of the pressure roller sliding track. Subsequently, the support plate 12 is swung in the opposite direction, causing the two bonding plates 11 to move closer together. Finally, the two bonding plates 11 are bonded together. At this time, the bonding plates 11 are held together on both sides of the sliding track through the engagement holes 111. The inner wall of the engagement holes 111 is in contact with the sliding track. The insertion protrusion 112 extends into the insertion groove. Thus, the placement of the gasket structure 1 is completed.
[0021] As the briquetting machine runs for a longer period, the gap between the two rollers gradually decreases. Eventually, the bonding plate 11 comes into contact with one of the rollers, and the support plate 12 comes into contact with the other roller. Thus, the gasket structure 1 is placed between the two rollers to adjust the gap between them. This prevents the gap between the rollers from becoming too small, which could affect their service life.
[0022] The widening device 2 includes a hydraulic cylinder 21 and a widening plate 22. The widening plate 22 is used to clamp the gasket structure 1. The widening plate 22 is placed at both ends of the hydraulic cylinder 21. The widening plate 22 is in contact with the ends of the hydraulic cylinder 21.
[0023] Specifically, the widening device 2 also includes an assembly plate 23 and a clamping plate 24. The assembly plate 23 corresponds one-to-one with the widening plate 22. The assembly plates 23 are respectively placed at both ends of the hydraulic cylinder 21. The assembly plates 23 are in contact with the ends of the hydraulic cylinder 21. The assembly plates 23 also correspond one-to-one with the clamping plates 24. The assembly plates 23 and clamping plates 24 are connected. The clamping plates 24 are respectively placed on both sides of the gasket structure 1. The clamping plates 24 are in contact with the gasket structure 1.
[0024] The widening device 2 also includes a support plate 25. The support plate 25 is connected to one of the clamping plates 24. The support plate 25 is disposed on the side of the gasket structure 1 closest to the ground. The length of the support plate 25 is greater than the width of the gasket structure 1.
[0025] In practical applications, the gap between the pressure rollers may be too small, preventing the gasket structure 1 from being directly placed between them. In this case, the gasket structure 1 is adjusted to the open state. That is, the support plate 12 is swung so that the two bonding plates 11 move away from each other. Subsequently, the gasket structure 1 is placed between the two clamping plates 24, so that one clamping plate 24 is in contact with the bonding plate 11, and the other clamping plate 24 is in contact with the support plate 12. At the same time, the bearing plate 25 is located below the gasket structure 1 and is in contact with the support plate 12.
[0026] After the gasket structure 1 is placed, the widening plate 22 is inserted into the gap between the two pressure rollers. The hydraulic cylinder 21 is activated, and under its push, the distance between the assembly plates 23 gradually increases, which in turn increases the distance between the widening plates 22. Driven by the widening plates 22, the gap between the pressure rollers gradually increases. Simultaneously, during the movement of the assembly plates 23, the clamping plates 24 also move synchronously, causing the distance between the two clamping plates 24 to gradually increase. When the gap between the pressure rollers increases to a certain extent, allowing the operator to insert the clamping plates 24 into the gap, the position of the device is adjusted so that the clamping plates 24 are positioned within the gap, and the overall position is adjusted so that the bearing plate 25 is positioned above the pressure roller sliding track.
[0027] As the distance between the assembly plates 23 increases, the clamping plate 24 will drive the bearing plate 25 to move synchronously. During the movement of the bearing plate 25, it will gradually separate from the gasket structure 1. Finally, when the assembly plates 23 have moved a certain distance, the bearing plate 25 will completely detach from the gasket structure 1. Because the length of the bearing plate 25 is greater than the width of the gasket structure 1, the distance the bearing plate 25 moves is greater than the width of the gasket structure 1. At this time, the distance between the pressure rollers provides enough space for the gasket structure 1 to fall. Thus, after the bearing plate 25 detaches from the gasket structure 1, the gasket structure 1 will fall onto the sliding track. At this point, the operator adjusts the gasket structure 1 so that it engages with the sliding track.
[0028] In summary, this greatly facilitates the actual operation for staff.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
