Description

Technical Field

[0001] The utility model relates to the technical field of cored wire equipment, in particular to a cored wire material guide device. Background Art

[0002] Cored wire is widely used in the foundry industry. Made from a steel strip wrapped around a smelting material, the wire is inserted into the desired position using specialized wire feeding equipment. Once the cored wire's outer layer melts, the core dissolves and chemically reacts in the desired position. This effectively prevents reactions between the smelting material and the hot air and slag, preventing waste and increasing the material's absorption rate. It also alters the morphology of molten steel inclusions, thereby improving the quality of steelmaking and casting products. For example, Chinese patent CN118291702A discloses a novel energy-saving and consumption-reducing cored wire device, relating to the technical field of cored wire equipment. The device includes a cored wire unit with an external mounting bracket. This new type of energy-saving and consumption-reducing cored wire device pours the smelted alloy particle raw material into any one storage hopper, and then pours the unsmelted magnesium raw material into another storage hopper. The second motor drives the second shaft to rotate, and under the action of the second auger, the raw material is transported to the mixing barrel and stirred and mixed. A specially designed channel can transport the magnesium raw material separately, without going through the smelting process, and directly put it into the mixing barrel for use, ensuring the convenience of loading. However, the smelting material in the cored wire has a distance from the feeding device to fall onto the steel belt. This makes it impossible to accurately control the amount and position of the smelting material falling on the steel belt during the manufacturing process of the cored wire, which can easily lead to uneven distribution. In severe cases, it can cause some smelting material to be stuck in the joint of the steel belt, thereby affecting the use effect of the product.

[0003] Therefore, it is necessary for those skilled in the art to provide a guide device for cored wire loading so that the smelting material can accurately fall onto the steel strip, ensure the uniformity of the distribution of the smelting material in the steel strip, and improve the use effect of the product. Utility Model Content

[0004] The utility model aims to provide a guide device for cored wire loading, so as to solve the technical problem in the prior art that the weight and position of smelting materials falling on the steel strip cannot be accurately controlled, which easily leads to uneven distribution and affects the use effect of the product.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a cored wire feeding guide device for feeding the cored wire, which is used for feeding the cored wire to the upper surface of the steel strip. The cored wire feeding guide device comprises a bracket, a feeding device arranged above the bracket and a guide device arranged on the bracket. The guide device is located below the feeding device. The steel strip can be slidably arranged on the bracket and pass through the guide device. The guide device can bend the strip-shaped steel strip into an arc shape. The feeding port of the feeding device faces the steel strip and can feed the cored wire to the upper surface of the steel strip. A limiting flow nozzle can be detachably connected to the feeding port of the feeding device, and one end of the limiting flow nozzle extends into the arc surface of the arc-shaped steel strip.

[0006] Furthermore, a mixing bin is provided in the discharge device, and a first discharge channel and a second discharge channel are provided on the discharge device, one end of the first discharge channel and the second discharge channel extend to the outside of the discharge device; the other ends of the first discharge channel and the second discharge channel are connected to the mixing bin, and the first discharge channel and the second discharge channel are isolated from each other.

[0007] Furthermore, the discharge port is arranged on the bottom wall of the discharge device, and the discharge port is a conical structure with a hollow interior. One end of the discharge port is connected to the mixing bin, and the other end of the discharge port faces the upper surface of the steel strip.

[0008] Furthermore, the flow limiting nozzle is detachably connected to one end of the discharge port close to the steel strip, and a flow channel is provided in the flow limiting nozzle, which passes through the flow limiting nozzle and is connected to the discharge port. The diameter of the flow limiting nozzle close to the steel strip is smaller than the diameter of the end away from the steel strip.

[0009] Furthermore, the flow limiting nozzle is threadedly connected to the discharge port at one end away from the steel belt, and the diameter of the flow channel at one end close to the steel belt is smaller than the diameter at one end away from the steel belt.

[0010] Furthermore, part of the steel strip is in a strip shape, and another part of the steel strip is bent in an arc shape, and the arc-shaped steel strip is close to the blanking device.

[0011] Furthermore, the guiding device includes a mounting seat and a limiting roller rotatably arranged in the mounting seat. The mounting seat is a groove-shaped structure with one side open. There are multiple limiting rollers and they are evenly arranged in the mounting seat. The limiting roller portion extends from the open surface of the mounting seat and can abut the bottom surface of the steel belt.

[0012] Furthermore, the guide devices are provided with two and are symmetrically arranged on both sides of the steel strip, and the distance between the ends of the two guide devices close to the blanking device is smaller than the distance between the ends of the two guide devices away from the blanking device.

[0013] Furthermore, the angle between the axis of the limiting roller on the guide device away from the end of the blanking device and the symmetry plane of the steel strip is β, and the angle between the axis of the limiting roller on the guide device close to the end of the blanking device and the symmetry plane of the steel strip is α, α<β, α>0°.

[0014] Furthermore, the plurality of limiting rollers on the guide device are evenly arranged and evenly deflected around the symmetry plane of the steel strip.

[0015] The beneficial effects of the present invention are as follows: by providing a replaceable flow-limiting nozzle at the discharge port, the flow-limiting nozzle is adaptively selected according to the particle size of the smelting material, thereby ensuring the accuracy of the discharge. At the same time, the flow-limiting nozzle can be closer to the upper surface of the steel strip, so that the smelting material in the discharge port can fall directly into the curved surface of the curved steel strip, preventing leakage, and improving the accuracy of the discharge. At the same time, the present invention also utilizes the gradually approaching distance between the limiting rollers and the gradually deflecting and decreasing angle to achieve the bending of the strip-shaped steel strip into an arc shape, thereby facilitating the feeding of the material. The curved steel strip can better receive the smelting material, ensuring the stability of the feeding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0026] See also Figure 1 The utility model provides a guide device for loading cored wires, which is used for unloading the cored wires onto the upper surface of a steel strip 40. The guide device for loading cored wires includes a bracket 10, a unloading device 20 arranged above the bracket 10, and a guide device 30 arranged on the bracket 10. The guide device 30 is located below the unloading device 20. The steel strip 40 can be slidably arranged on the bracket 10 and pass through the guide device 30. The guide device 30 can bend the strip-shaped steel strip 40 into an arc shape. The unloading port of the unloading device 20 faces the steel strip 40 and can unload the cored wire onto the upper surface of the steel strip 40, thereby realizing the unloading process.

[0027] Further, see Figure 2 、 Figure 3 The unloading device 20 is provided with a mixing bin 21. It is also equipped with a first unloading channel 22 and a second unloading channel 23. One end of the first unloading channel 22 and the second unloading channel 23 extends outside the unloading device 20 for connection to a feeding device. The other ends of the first unloading channel 22 and the second unloading channel 23 communicate with the mixing bin 21. The first unloading channel 22 and the second unloading channel 23 are isolated from each other, thereby enabling the injection of different smelting materials into the mixing bin 21. The bottom wall of the unloading device 20 is provided with a unloading port 24. The unloading port 24 has a hollow, conical structure. One end of the unloading port 24 communicates with the mixing bin 21, while the other end faces the upper surface of the steel strip 40. By limiting the size of the unloading area of the unloading port 24, the discharge amount can be controlled.

[0028] Further, see Figure 4 、 Figure 5 The end of the discharge port 24 near the steel strip 40 is detachably connected to a flow limiting nozzle 25, which has a flow channel 26 therein. The flow channel 26 passes through the flow limiting nozzle 25 and connects to the discharge port 24. The diameter of the flow limiting nozzle 25 near the steel strip 40 is smaller than the diameter of the end away from the steel strip 40.

[0029] Part of the steel strip 40 is in the shape of a strip, and the other part of the steel strip 40 is bent into an arc shape by the guide device 30. The arc-shaped steel strip 40 is close to the blanking device 20, and the end of the flow limiting nozzle 25 close to the steel strip 40 extends into the arc surface of the arc-shaped steel strip 40, so that the smelting material in the blanking port 24 can directly fall into the arc surface of the arc-shaped steel strip 40, preventing leakage and improving the accuracy of blanking.

[0030] The flow restrictor 25 is threadedly connected to the discharge port 24 at the end away from the steel strip 40. The diameter of the flow channel 26 at the end close to the steel strip 40 is smaller than the diameter at the end away from the steel strip 40. During use, the flow restrictor 25 is adaptively selected according to the particle size of the smelting material to further ensure the accuracy of material discharge.

[0031] Further, see Figure 6 、 Figure 7 、 Figure 8 The guide device 30 includes a mounting seat 31 and a limiting roller 32 rotatably arranged in the mounting seat 31. The mounting seat 31 is a groove-shaped structure with one side open. There are multiple limiting rollers 32 and they are evenly arranged in the mounting seat 31. Part of the limiting roller 32 extends from the open surface of the mounting seat 31 and can abut the bottom surface of the steel belt 40.

[0032] The guide devices 30 are provided with two and are symmetrically arranged on both sides of the steel belt 40. The distance between the ends of the two guide devices 30 close to the blanking device 20 is smaller than the distance between the ends of the two guide devices 30 away from the blanking device 20. The bending of the steel belt 40 is achieved by utilizing the continuously approaching distance between the two guide devices 30 and the limiting rollers 32 on the guide devices 30 that abut against the bottom surface of the steel belt 40.

[0033] The included angle between the axis of the limiting roller 32 on the end of the guide device 30 away from the blanking device 20 and the symmetric plane of the steel strip 40 is β, and the included angle between the axis of the limiting roller 32 on the end of the guide device 30 close to the blanking device 20 and the symmetric plane of the steel strip 40 is α, α<β, α>0°. The multiple limiting rollers 32 on the guide device 30 are evenly arranged and uniformly deflected around the symmetric plane of the steel strip 40. That is, the included angle between the limiting rollers 32 on the guide device 30 and the symmetric plane of the steel strip 40 gradually changes from β to α. When α is 0, the axis of the limiting roller 32 and the symmetric plane of the steel strip 40 are parallel to each other.

[0034] When in use, the steel belt 40 passes between the two guide devices 30, and the bottom surface of the steel belt 40 abuts against the limiting roller 32. The gradually approaching distance between the limiting rollers 32 and the gradually deflected and reduced angle are utilized to bend the strip-shaped steel belt 40 into an arc shape, thereby facilitating loading. The arc-shaped steel belt 40 can better receive the smelting material and ensure loading stability.

[0035] It can be understood that the symmetry plane between the steel belts 40 refers to the symmetry plane between the two long sides of the steel belt 40. The steel belt 40 passes between the two guide devices 30 under the drive of the traction device, and the moving direction of the steel belt 40 remains stable. When it passes between the two guide devices 30, the deflected limiting roller 32 on the guide device 30 continuously squeezes the steel belt 40, so that the steel belt 40 continues to bend according to a stable angle, thereby realizing the bending of the strip-shaped steel belt 40 into an arc shape.

[0036] The specific operation method of the present invention is as follows: a flow limiting nozzle 25 is installed on the lowering device 30, and the traction device is used to pass the steel belt 40 between the two guide devices 30. At the same time, the steel belt 40 passes under the lowering device 20. The lowering port of the lowering device 20 is facing the steel belt 40 and can discharge the steel belt 40 to the upper surface of the steel belt 40 to complete the lowering operation.

[0037] The present invention provides a replaceable flow-limiting nozzle 25 on the discharge port 24. The flow-limiting nozzle 25 is adaptively selected based on the particle size of the smelting material to ensure the accuracy of the discharge. At the same time, the flow-limiting nozzle 25 can be closer to the upper surface of the steel strip 40, so that the smelting material in the discharge port 24 can fall directly into the curved surface of the curved steel strip 40, preventing leakage and improving the accuracy of the discharge. At the same time, the present invention also utilizes the gradually approaching distance between the limiting rollers 32 and the gradually deflecting and decreasing angle to achieve the bending of the strip-shaped steel strip 40 into an arc shape, thereby facilitating the discharge of the material. The curved steel strip 40 can better receive the smelting material, ensuring the stability of the discharge.

[0038] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
