[0033] See also Figure 1 and Figure 3 , Figure 1 A schematic diagram of the structure of an automatic charging device 100 for an induction furnace provided in an embodiment of the utility model; Figure 2 A schematic diagram of the structure of a silo mechanism 10 in an automatic charging device for an induction furnace provided in an embodiment of the utility model; Figure 3 It is a partial structural schematic diagram of the feeding mechanism 20 in the automatic feeding device for an induction furnace provided in an embodiment of the utility model.

[0034] The embodiment of the utility model first provides an automatic charging device 100 for an induction furnace, including a silo mechanism 10 and a charging mechanism 20. The silo mechanism 10 includes a silo body 11 and a silo cover 12 for charging. The silo body 11 includes a charging port 111 at its top. The silo cover 12 is connected to the upper side of the charging port 111 in the vertical direction and can be flipped relative to the silo body 11 to close or open the charging port 111.

[0035] The feeding mechanism 20 includes a guide rail 21, a lifting structure 22 and a hopper 23. The guide rail 21 is arranged on the upper side of the silo mechanism 10 in the vertical direction. The lifting structure 22 is slidably connected to the guide rail 21 to move along the guide rail 21. The lifting structure 22 includes a lifting rope 221. The lifting rope 221 is connected to the hopper 23. The hopper 23 is pulled up or down by the lifting rope 221, and the angle of the hopper 23 can be changed.

[0036] It can be understood that the automatic feeding device 100 for the induction furnace is mainly used to automatically add materials to the induction furnace 200, wherein the main function of the silo mechanism 10 is to guide the materials and ensure that the materials can smoothly enter the induction furnace 200, which includes a silo body 11 that can accommodate materials, and a feeding port 111 is provided at the top of the silo body to facilitate the addition of materials, and a silo cover 12 is provided at the feeding port 111, and the silo cover 12 can be flipped in the vertical direction to close or open the feeding port 111 to ensure that the materials are prevented from overflowing when not feeding. The feeding mechanism 20 is the key part for realizing automatic feeding, which includes a guide rail 21, a hoisting structure 22 and a hopper 23. The guide rail 21 is arranged on the upper side of the silo mechanism 10 in the vertical direction, providing a moving path for the hoisting structure 22, so as to transport the materials to the upper side of the feeding port 111; the hoisting structure 22 includes a hoisting rope 221, and the hoisting rope 221 is connected to the hopper 23. By the traction of the suspension rope 221, the hopper 23 can rise or fall, and the vertical conveying of the material is realized. In addition, the suspension rope 221 can also change the angle of the hopper 23 so that the material is poured into the charging port 111 from the hopper 23 smoothly.

[0037] Therefore, the induction furnace automatic charging device 100 can realize an automatic and efficient charging process, avoiding the inconvenience and potential safety risks of manual charging. The automation level is high, while reducing the error rate of manual operation. Compared with the prior art, the overhead crane charging can improve the charging efficiency, reduce the operation risk, and reduce the maintenance cost.

[0038] Furthermore, the bin body 11 can be set on the top or periphery of the induction furnace 200, and is preferably connected to the periphery of the induction furnace 200, wherein the bin body 11 can be set to have a certain angle, or be set horizontally and have a built-in automatic conveyor belt (not shown in the figure) to add materials into the induction furnace 200.

[0039] like Figure 2 Furthermore, the bin body 11 and the bin cover 12 are connected by a hinge structure 13, and the hinge structure 13 includes a support rib 131 and a hinge seat 132; wherein the support rib 131 is configured to be L-shaped, and its long side is connected to the upper side of the bin cover 12 and extends along the width direction of the bin cover 12; the hinge seat 131 is connected to the outer wall of the bin body 11 and is hinged to the end of the short side of the support rib 131.

[0040] It can be understood that the support ribs 131 can provide structural support for the bin cover 12, ensuring the structural stability and strength of the bin cover 12, so that it can be flexibly opened and closed. The hinge seat 132 is connected to the outer wall of the side of the bin body 11, and is hinged to the end of the short side of the support rib 131. This allows the bin cover 12 to rotate around this point to achieve the opening and closing action with the bin body 11. Through such a hinge structure design, the bin mechanism 10 of the automatic charging device of the induction furnace can be easily opened and closed during the charging operation, while also ensuring the close connection between the bin body 11 and the bin cover 12 to prevent material overflow. In addition, the sturdiness and durability of the support ribs 131 and the hinge seat 132 ensure the stability and service life of the entire device and avoid deformation of the bin cover 12.

[0041] Furthermore, the silo mechanism 10 further includes a baffle 14, which is disposed at the edge of the feed port 111. When materials are added to the silo 23, the baffle 14 can prevent the materials from splashing or overflowing the feed port 111, thereby ensuring accurate measurement and storage of the materials and keeping the interior of the silo clean.

[0042] like Figure 3 The guide rail 21 includes two parallel linear guide rails 211, and the hoisting structure 22 includes:

[0043] The first slide 222 and the second slide 223 are respectively slidably connected to the linear guide rail 211;

[0044] The first electric hoist 224 and the second electric hoist 225 are fixedly connected to the first slide 222 and the second slide 223 respectively. The first electric hoist 224 and the second electric hoist 225 are respectively connected to the lifting rope 221. The other end of the lifting rope 221 away from the electric hoist is connected to both sides of the hopper 23. The first electric hoist 224 and the second electric hoist 225 control the lifting rope 221 to pull the hopper up or down and change the angle of the hopper 23.

[0045] It can be understood that the guide rail 21 includes two parallel linear guide rails 211, which provide a more stable and reliable sliding path, so that the hoisting structure 22 can transport the hopper from the loading area to the silo mechanism 10 along the guide rails 21. The hoisting structure 22 further includes a first slide 222 and a second slide 223, which are respectively slidably connected to the linear guide rails 211. To increase the overall stability and load capacity of the hoisting structure 22. The first slide 222 and the second slide 223 are also fixedly connected to an electric hoist, namely a first electric hoist 224 and a second electric hoist 225, which are used to control the lifting and lowering and angle changes of the hoisting ropes 221221.

[0046] Specifically, the first electric hoist 224 and the second electric hoist 225 are respectively connected with a section of a suspension rope 221. The other ends of these suspension ropes 221 are away from the electric hoist and connected to the two sides of the hopper 23. By controlling the first electric hoist 224 and the second electric hoist 225 to rotate synchronously, the material head 23 can be controlled to rise. On the contrary, the first electric hoist 224 and the second electric hoist 225 are reversed, and the hopper 23 is lowered at this time; if the first electric hoist 224 and the second electric hoist 225 rotate asynchronously, the lengths of the suspension ropes 221 on both sides of the hopper 23 will gradually become inconsistent. For example, when the hopper 23 rises, the speed of the first electric hoist 224 is controlled to be greater than that of the second electric hoist 225. At this time, the suspension rope corresponding to the first electric hoist 224 is shorter than the suspension rope of the second electric hoist 225, and the hopper 23 will be tilted at an angle, so as to realize the tilting and pouring of the materials in the hopper 23.

[0047] Furthermore, the induction furnace automatic feeding device 100 also includes a visual mechanism 31 and a laser radar 32, and the visual mechanism 31 and the laser radar 32 are connected to any one of the first slide 222 and the second slide 223. This connection mode enables the visual mechanism 31 and the laser radar 32 to move with the movement of the slide, so that the working state of the induction furnace 200 and the position and posture of the hopper 23 can be monitored in real time. The visual mechanism 31 usually includes one or more cameras for capturing images of the induction furnace 200 and the hopper 23. Through image processing and analysis, the visual mechanism 31 can identify information such as the material state in the furnace, the position and posture of the hopper. This information is used to further control the feeding process, such as adjusting the placement position and angle of the hopper, or determining whether a feeding operation is required. The laser radar 32 measures the distance and angle between the hopper 23 or the silo mechanism 10 and the laser radar by emitting a laser beam and receiving the reflected signal. The posture information of the hopper 23 and the material condition in the feeding port 111 can be quickly and accurately obtained, providing key feedback information for the automatic control system. Based on this information, the control system can more intelligently adjust the position and angle of the hopper to ensure the accuracy and efficiency of the feeding. By integrating the visual mechanism 31 and the laser radar 32, the induction furnace automatic feeding device 100 can achieve more advanced intelligent functions. For example, it can automatically identify the distribution and state of the materials in the furnace and dynamically adjust the feeding strategy; monitor the position and posture of the hopper 23 in real time and automatically correct the deviation; combine the working state of the induction furnace 200 and the feeding demand to achieve adaptive feeding control, etc.

[0048] Further, the induction furnace automatic charging device 100 also includes a multi-side tilt sensor (not shown), which is connected to the hopper 23 to read the angle of the hopper 23 in at least one horizontal direction. The main function of the multi-side tilt sensor is to read the angle change of the hopper 23 in the horizontal direction. Generally, this sensor has multiple sensors or measuring elements, so that it can simultaneously detect the tilt angle of the hopper in at least two different directions. By detecting the tilt angle of the hopper in multiple directions, its tilt state can be more accurately judged, thereby providing real-time feedback for the first electric hoist 224 and the second electric hoist 225. For example, when the hopper 23 tilts in a certain direction, the sensor will immediately capture this change and transmit the signal to the control unit of the first electric hoist 224 and the second electric hoist 225. The control unit will then feedback adjust (i.e., PID adjust) the rotation speed of the first electric hoist 224 and the second electric hoist 225 according to the received data to adjust the position or posture of the hopper 23 in real time to ensure the stability and accuracy of the charging process. In addition, the use of multi-tilt sensors can also help prevent problems such as material spillage or uneven feeding caused by hopper tilt. By real-time monitoring and adjustment of the hopper tilt state, it can ensure that the material always maintains proper distribution and flow during the feeding process, thereby improving production efficiency and product quality.

[0049] Furthermore, the induction furnace automatic feeding device 100 also includes a weight sensor, which can be optionally a crane scale. The weight sensor is arranged at the hoisting structure 22 to sense the weight data of the hopper 23 to provide data for automatic feeding; and when the material in the hopper 23 exceeds the preset limit, an alarm can be triggered or other safety measures can be taken to prevent the hoisting structure 22 from being overloaded or damaged.

[0050] In the embodiment of the utility model, the feeding mechanism 20 also includes a connecting structure 24, which is arranged at the connection between the hopper 23 and the lifting rope 221. Specifically, the connecting structure 24 includes a buckle 241, a counterweight connecting block 242 and a fixed clamp arm 243; one end of the counterweight connecting block 242 is connected to the buckle 241, and is directly buckled with the buckle 241 and the lifting rope 221, and the other end is screwed to the fixed clamp arm 243, and at the same time, the fixed clamp arm 243 is fixedly connected to the upper side of the hopper 23 at one end away from the connection 242.

[0051] It can be understood that the connecting structure 24 can keep the hopper 23 balanced, especially when there is less material in the hopper 23 or it is empty, effectively reducing the shaking of the hopper 23; at the same time, the design of the connecting structure 24 also takes into account the convenience of installation and maintenance, through the buckle 241 and the sling 221 adopting a buckling method, and the counterweight connecting block 242 and the fixed clamp arm 243; are directly threadedly connected. When maintenance is required, or when replacing a hopper of other sizes, the hopper 23 and the fixed clamp arm 243 can be conveniently adjusted or replaced together, without the need for complicated disassembly and assembly processes, thereby speeding up work efficiency.

[0052] Furthermore, a stopper 25 is provided on the guide rail 21 to constrain the sliding stroke of the first slide 222 and the second slide 223 on the linear guide rail 211. The slide is ensured to move within a predetermined range and prevented from exceeding the set stroke, thereby ensuring the normal operation and safety of the entire device.

[0053] Continue reading Figure 1 The induction furnace automatic charging device 100 also includes a bracket mechanism 40 for providing structural support. The silo mechanism 10 and the charging mechanism 20 are both connected to the bracket mechanism 40, and an area for personnel operation and monitoring can be provided.

[0054] Continue to combine Figures 1 to 5 , Figure 4 This is a front view of the automatic charging device 100 for an induction furnace provided by the embodiment of the utility model, when the hopper 23 is in the charging state, Figure 5 It is an axial schematic diagram when the hopper 23 is in the feeding state.

[0055] like Figure 1 In the initial state, the hoisting structure 22 carries the hopper 23 and is located at the end of the guide rail 21 away from the silo mechanism 10. The hoisting structure 22 lengthens the hoisting rope 221 to lower the hopper 23, so that the hopper 23 is located in the feeding area and is convenient for loading. The loading can be optionally automatic loading by a conveyor belt. When the material is loaded (the conveyor belt moves to the target position and the weight of the hopper 23 reaches the target value), the hoisting structure 22 pulls up the hopper 23 synchronously through the first electric hoist 224 and the second electric hoist 225. When the hopper 23 is pulled to the target height, the hoisting structure 22 slides along the guide rail 21 to the upper side of the silo mechanism 10. At this time, after the visual mechanism 31 determines that the required target position has been reached, the silo cover 12 flips to open the feeding port 111, and the laser radar 32 starts synchronous scanning. The first electric hoist 224 and the second electric hoist 225 operate asynchronously at this time, so that the hopper 23 is tilted. Figure 4 and Figure 5As shown. When the material enters the feeding port 111, the laser radar 32 starts to combine the posture information of the hopper 23 and the three-dimensional information of the material at the feeding port 111, and continuously fine-adjusts the position and angle of the hopper 23 to avoid concentrated blockage of the material; when the feeding is completed, the bin cover 12 covers the feeding port 111, and the hoisting structure 22 carries the hopper 23 back to the initial state, and the entire automated feeding work is completed.

[0056] In summary, an automatic feeding device 100 for an induction furnace provided by an embodiment of the utility model comprises a silo mechanism 10 and a feeding mechanism 20. The silo mechanism 10 comprises a silo body 11 and a silo cover 12 located at a feeding port 111. The silo cover 12 is reversible to achieve closure or semi-closure to ensure that no other impurities enter during a non-feeding process. The feeding mechanism 20 realizes automatic feeding through a guide rail 21, a hoisting structure 22 and a hopper 23. The hoisting structure 22 comprises a hoisting rope 221, through which the hopper 23 is pulled up or down, and the angle of the hopper can be changed. The automatic feeding device 100 for an induction furnace reduces the number of manual operations, improves the efficiency and accuracy of feeding, greatly improves the efficiency of feeding through automatic feeding, accurately controls the amount and time of feeding, avoids the uncertainty and error of manual operation, and helps to improve the quality and stability of the product.
