[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] See also Figs. 1 to 4 As shown, according to an embodiment of this application, an automatic feeding device for slag-blocking rods is provided, including a transport section 1, a feeding section 2, and a dispensing section 3. The feeding section 2 includes a clamping unit and a driving unit. The clamping unit is used to pick up and put down the slag-blocking rods 4. The driving unit is connected to the clamping unit to drive the clamping unit to move, so as to move the slag-blocking rods 4 on the clamping unit from the loading position 51 to the dispensing position 52. The discharge end of the transport section 1 is set at the loading position 51, and a first baffle block 14 is provided on the discharge end. The clamping unit includes a second baffle block 27. The first baffle block 14 and the second baffle block 27 extend to the loading position 51 to position the slag-blocking rods 4. The feeding end of the dispensing section 3 is set at the dispensing position 52.

[0023] By setting up a transportation section 1, a loading section 2, and a dispensing section 3, the slag-blocking bar 4 is automated from conveying to loading, reducing the labor intensity of manual labor, minimizing the impact of harsh working environments on workers, and avoiding slag-blocking failures caused by human error. This significantly improves the stability, accuracy, and efficiency of the loading process, providing a reliable guarantee for the continuous production of the steel plant. By extending the first retaining block 14 and the second retaining block 27 to the loading position 51, the slag-blocking bar 4 can be precisely positioned, preventing it from shifting during loading and ensuring that the loading section 2 can accurately grasp the slag-blocking bar 4.

[0024] The feeding section 2 includes a clamping unit for picking up and placing the slag-blocking rod 4 and a driving unit for providing power. The driving unit is connected to the clamping unit and can output power to move the clamping unit. The discharge end of the transport section 1 is located at the loading position 51. A first baffle block 14 is installed on the discharge end, and a second baffle block 27 is integrated on the clamping unit. Both the first baffle block 14 and the second baffle block 27 extend towards the loading position 51. The first baffle block 14 and the second baffle block 27 cooperate to form a positioning structure, thereby fixing the position of the slag-blocking rod 4 to be clamped. The feeding end of the dispensing section 3 is located at the picking position 52, forming a transfer connection with the loading position 51. During operation, the transport unit 1 transports the slag-blocking rod 4 from the storage area to the loading position 51. The first baffle block 14 and the second baffle block 27 work together to position the slag-blocking rod 4, ensuring that the clamping unit can accurately clamp it. Then, the drive unit drives the clamping unit to move the slag-blocking rod 4 from the loading position 51 to the material-retrieving position 52. The dispensing unit 3 receives the slag-blocking rod 4 from the material-retrieving position 52, completing the feeding process.

[0025] In one embodiment, the loading unit 2 includes a rotating loading frame 21, the driving unit includes a first driving mechanism, the first driving mechanism is connected to the rotating loading frame 21 to drive the rotating loading frame 21 to rotate, and the clamping unit is movably mounted on the rotating loading frame 21.

[0026] By setting up a rotating feeding frame 21 and a first drive mechanism, the clamping unit can rotate, improving the spatial adaptability and operational flexibility of the automatic feeding device. The rotation of the rotating feeding frame 21 can adjust the orientation of the clamping unit, allowing the automatic feeding device to adapt to different installation layouts and material handling angle requirements of the feeding section 3 without requiring significant adjustments to the entire automatic feeding device. The clamping unit is movably mounted on the rotating feeding frame 21, allowing it to not only rotate and adjust its angle with the rotating feeding frame 21, but also move on the rotating feeding frame 21, ensuring that the slag-blocking rod 4 can accurately align with the feeding end of the feeding section 3. This effectively expands the applicability of the automatic feeding device and improves the adaptability and efficiency of automated operations.

[0027] The rotating feeding rack 21 serves as the mounting carrier for the clamping unit. The drive unit includes a first drive mechanism connected to the rotating feeding rack 21, which outputs rotational power to drive the rotating feeding rack 21 to rotate. The clamping unit is mounted on the rotating feeding rack 21 in a movable manner, allowing it to slide or move in other ways along the extension direction of the rotating feeding rack 21. During operation, the first drive mechanism starts and outputs power, driving the rotating feeding rack 21 to rotate, which in turn drives the clamping unit mounted on it to rotate synchronously, adjusting it to an angle corresponding to the loading position 51 of the transport section 1, facilitating the clamping unit to clamp the slag-blocking rod 4. After clamping, the first drive mechanism drives the rotating feeding rack 21 to rotate again, adjusting the clamping unit and the slag-blocking rod 4 to an angle corresponding to the material-receiving position 52 of the delivery section 3, preparing for the subsequent transfer of the slag-blocking rod 4 to the material-receiving position 52. During this process, the clamping unit can move on the rotating feeding rack 21 to ensure precise docking.

[0028] In one embodiment, the first driving mechanism includes a first driving member and a slewing bearing 22, the rotating feeder 21 is rotatably connected to the slewing bearing 22, and the first driving member is drivingly connected to the slewing bearing 22.

[0029] The slewing bearing 22 features high load-bearing capacity, smooth rotation, and high positioning accuracy, providing stable support for the rotating feeder 21 while reducing frictional resistance during rotation, ensuring smooth and uninterrupted rotation of the rotating feeder 21. The first driving component is connected to the slewing bearing 22, accurately transmitting power to the slewing bearing 22 and then to the rotating feeder 21. While driving the rotating feeder 21 to rotate, it achieves precise control over the rotation speed and angle, improving the reliability, stability, and accuracy of the rotating feeder 21's rotation. This provides precise assurance for the angle adjustment of the clamping unit, ensuring accurate angular positioning of the slag-blocking rod 4 during transfer, further reducing the incidence of feeding failures and improving the overall operational stability of the automatic feeding device.

[0030] The slewing bearing 22 is fixedly mounted on the frame or other fixed structure of the automatic feeding device. The rotating feeding frame 21 is rotatably connected through the slewing bearing 22, which provides support for the rotating feeding frame 21 and allows it to rotate around its rotation center. The first driving component can be a power output component such as a motor or hydraulic motor, with a gear at its output end. The gear meshes with the outer ring teeth of the slewing bearing 22, driving the slewing bearing 22 to rotate, which in turn drives the rotating feeding frame 21 to rotate.

[0031] Specifically, the first driving component can be a servo motor.

[0032] In one embodiment, the drive unit further includes a second drive mechanism connected to the rotating feeder 21, and the clamping unit is driven to move by the second drive mechanism.

[0033] By setting a second drive mechanism and driving it to the clamping unit, the clamping unit can both adjust its rotation angle with the rotating feeding frame 21 and move independently on the rotating feeding frame 21 under the drive of the second drive mechanism. This further refines the motion control of the clamping unit, making the transfer process of the slag-blocking rod 4 more flexible and precise. The rotational motion allows for orientation adjustment to adapt to different material picking and unloading requirements. Independent movement on the rotating feeding frame 21 allows for position adjustment of the slag-blocking rod 4 in a specific direction, ensuring that the slag-blocking rod 4 can accurately move from the loading position 51 to the picking position 52. This effectively improves the adaptability of the automatic feeding device to different operating scenarios and different sizes of slag-blocking rods 4, further optimizing the automated feeding process and improving feeding efficiency and accuracy.

[0034] The second drive mechanism is fixedly connected to the rotating feeder 21 via bolts, welding, or other methods, and rotates synchronously with the rotating feeder 21. The clamping unit establishes a drive connection with the second drive mechanism, which outputs power to move the clamping unit relative to the rotating feeder 21. During operation, the first drive mechanism drives the rotating feeder 21 to rotate, causing the second drive mechanism and the clamping unit to adjust their orientation together. Once the appropriate orientation is achieved, the second drive mechanism activates, outputting power to move the clamping unit on the rotating feeder 21, thus adjusting the position of the clamping unit in a specific direction.

[0035] In one embodiment, the second drive mechanism includes a lead screw 24 assembly and a second drive member 23, the second drive member 23 being drivenly connected to the lead screw 24 in the lead screw 24 assembly, and the clamping unit being disposed on the slider 25 in the lead screw 24 assembly. The lead screw 24 transmission is a high-precision transmission method with advantages such as high transmission efficiency, high positioning accuracy, smooth operation, and good repeatability. By driving the second drive component 23 to the lead screw 24, the rotation speed and angle of the lead screw 24 can be precisely controlled. Furthermore, through the cooperation of the lead screw 24 and the slider 25, precise control of the moving distance and speed of the clamping unit can be achieved. This effectively prevents the clamping unit from shifting or shaking during movement, ensuring the stability of the slag-blocking rod 4 during transfer and preventing it from falling or colliding due to unstable movement. Simultaneously, the high-precision transmission control allows the clamping unit to accurately stop at the designated position, ensuring that the slag-blocking rod 4 can precisely align with the loading position 51 and the unloading position 52, further improving the accuracy and reliability of the feeding process and meeting the steel plant's requirements for high-precision operation of automated equipment.

[0036] The lead screw 24 assembly includes a lead screw 24 and a slider 25. The lead screw 24 is rotatably mounted on the rotating feeder 21 via bearings and other components. The slider 25 is fitted onto the lead screw 24 and forms a threaded engagement with it. When the lead screw 24 rotates, it drives the slider 25 to move along the axis of the lead screw 24. The second drive unit 23 can be a power component with precise control capabilities, such as a servo motor or a stepper motor. The output end of the second drive unit 23 is connected to the lead screw 24 in the lead screw 24 assembly via a coupling or other connection structure to drive the lead screw 24 to rotate forward or in reverse. The clamping unit is fixedly mounted on the slider 25 of the lead screw 24 assembly via bolts or other means and moves synchronously with the slider 25. During operation, the second drive unit 23 starts after receiving a control signal, driving the lead screw 24 to rotate. The lead screw 24 drives the slider 25 to move along the axis of the lead screw 24 through thread transmission. The slider 25 then drives the clamping unit installed on it to move synchronously, realizing the linear movement of the clamping unit on the rotating feeder 21. By controlling the operating parameters of the second drive unit 23, the moving distance and moving speed of the clamping unit can be precisely controlled to meet the position requirements for clamping and transferring the slag-blocking rod 4.

[0037] Specifically, in this embodiment, the second driving component 23 can be a servo motor.

[0038] In one embodiment, the lead screw 24 extends in the same direction as the rotary feeder 21, and the rotary feeder 21 is perpendicular to the transport section 1 when the clamping unit clamps the slag-blocking rod 4 from the loading position 51.

[0039] By extending the lead screw 24 in the same direction as the rotary feeding frame 21, the moving direction of the clamping unit is consistent with the extending direction of the rotary feeding frame 21, which facilitates the planning and control of the moving trajectory of the clamping unit and improves the accuracy and stability of the movement. When the clamping unit picks up the slag-blocking rod 4 from the loading position 51, the rotary feeding frame 21 is set perpendicular to the transport section 1, which optimizes the overall structure of the automatic feeding device. At the same time, the vertical layout allows the discharge end of the transport section 1 to form a vertical connection with the clamping unit on the rotary feeding frame 21. After the slag-blocking rod 4 is transported from the transport section 1 to the loading position 51, the clamping unit can directly pick it up from the vertical direction, shortening the clamping time, improving the feeding efficiency, and effectively avoiding interference between the clamping unit and the transport section 1, ensuring a smooth feeding process.

[0040] The axis of the lead screw 24 is aligned with the extension direction of the rotary feeder 21, and both are arranged in the same direction. This ensures that when the slider 25 moves the clamping unit along the lead screw 24, the direction of movement is the same as the extension direction of the rotary feeder 21. When the clamping unit picks up the slag-blocking rod 4 from the loading position 51, the rotary feeder 21 is arranged perpendicular to the transport section 1, meaning that the extension direction of the rotary feeder 21 is perpendicular to the conveying direction of the transport section 1.

[0041] In one embodiment, the clamping unit includes a gripper 26, the gripper 26 and a second baffle block 27 are disposed on the slider 25, and the second baffle block 27 is provided with a receiving bracket 28. The gripper 26 is used to clamp the slag-blocking rod 4 at the loading position 51, and the receiving bracket 28 is used to abut against the conical surface of the slag-blocking rod 4.

[0042] By setting a gripper 26 and a second baffle block 27 with a receiving bracket 28, both mounted on the slider 25, an integrated design of clamping, positioning, and support functions is achieved. The gripper 26 can firmly clamp the slag-blocking rod 4 to prevent it from loosening and falling off during transportation. The second baffle block 27 not only works with the first baffle block 14 to position the slag-blocking rod 4, but its receiving bracket 28 can also abut against the conical surface of the slag-blocking rod 4 to form effective support. At the same time, through the dual fixation of clamping and support, the stability of the slag-blocking rod 4 during transportation is greatly improved. Even during complex movements such as rotation and movement, the slag-blocking rod 4 can maintain a stable posture and will not tilt or shake.

[0043] The clamping unit includes grippers 26 for clamping the slag-blocking rod 4. Both grippers 26 and the second baffle block 27 are fixedly mounted on the slider 25 via bolts or other means, and move synchronously with the slider 25. A receiving bracket 28 is located at the end of the second baffle block 27 furthest from the rotating loading frame 21, i.e., at the end closest to the transport unit 1. The shape of the receiving bracket 28 is adapted to the conical shape of the slag-blocking rod 4, allowing it to abut tightly against the conical surface of the slag-blocking rod 4. During operation, after the slag-blocking rod 4 is transported to the loading position 51 by the transport unit 1, the first baffle block 14 and the second baffle block 27 cooperate to position the slag-blocking rod 4 in a preset clamping position. Subsequently, the grippers 26 operate under the action of the drive mechanism, clamping the slag-blocking rod 4 from both sides or a specific direction, thus achieving clamping and fixing of the slag-blocking rod 4. Meanwhile, the receiving bracket 28 abuts against the conical surface of the slag-blocking rod 4 and provides support for the slag-blocking rod 4 from below and the side. This works in conjunction with the clamping force of the gripper 26 to firmly fix the slag-blocking rod 4 on the clamping unit. During subsequent rotation, movement and other transfer processes, the slag-blocking rod 4 remains stable, preventing it from loosening, tilting or falling off.

[0044] As a feasible embodiment, the gripper 26 can be pneumatically controlled to open and close.

[0045] When the clamping unit picks up the slag-blocking rod 4 from the loading position 51, a gap is left between the receiving bracket 28 and the transport section 1 to avoid interference.

[0046] In one embodiment, the transport unit 1 includes a belt conveyor mechanism, a slag-blocking rod 4 is disposed on the belt conveyor mechanism, the belt conveyor mechanism includes a first side and a second side opposite to each other in the width direction, a first baffle block 14 is disposed on the first side, and the second side is provided with a clearance notch 13 so that the slag-blocking rod 4 can be rotated out of the belt conveyor mechanism through the clearance notch 13, and the second baffle block 27 extends the clearance notch 13.

[0047] The belt conveyor mechanism has the advantages of stable conveying, high conveying efficiency, and minimal damage to the slag-blocking rod 4, enabling continuous and stable conveying of the slag-blocking rod 4. An avoidance notch 13 is provided on the second side of the belt conveyor mechanism, allowing the second baffle block 27 to extend to this notch. This ensures the positioning function of the first baffle block 14 and the second baffle block 27 for the slag-blocking rod 4, while also providing ample space for the rotation and removal of the slag-blocking rod 4. When the clamping unit grips the slag-blocking rod 4 and it needs to rotate away from the belt conveyor mechanism along with the rotating feeder 21, the avoidance notch 13 prevents the slag-blocking rod 4 from colliding with or interfering with the second edge of the belt conveyor mechanism. This ensures that the slag-blocking rod 4 can rotate and move out smoothly and stably, without interference causing it to fall, be damaged, or malfunction of the automatic feeding device.

[0048] The transport section 1 is a belt conveyor mechanism. The slag-blocking rod 4 is placed flat on the belt of the belt conveyor mechanism and is transported to the loading position 51 as the belt rotates. The belt conveyor mechanism is divided into a first side and a second side along its width. The first baffle block 14 is fixedly installed at the edge of the first side and extends towards the conveying surface of the belt. The second side does not have a complete belt edge structure, but instead forms an avoidance notch 13. The second baffle block 27 extends from the clamping unit towards the avoidance notch 13, partially extending into the notch. During operation, the belt conveyor mechanism starts, driving the slag-blocking rod 4 to move towards the loading position 51. When the slag-blocking rod 4 reaches the loading position 51, the first baffle block 14 limits the slag-blocking rod 4 from the first side, and the second baffle block 27 limits the slag-blocking rod 4 from the avoidance notch 13. The two work together to position the slag-blocking rod 4. After the clamping unit's gripper 26 clamps the slag-blocking rod 4, the rotating feeding frame 21 drives the clamping unit and the slag-blocking rod 4 to rotate. Since the second side is provided with an avoidance notch 13, the slag-blocking rod 4 will not collide with the second side of the belt conveyor during rotation. It can smoothly rotate out of the belt conveyor through the avoidance notch 13 and enter the subsequent transfer process.

[0049] In one embodiment, the belt conveyor mechanism includes a first belt 11 and a second belt 12, which are arranged in parallel. The first belt 11 is located on a first side and the second belt 12 is located on a second side. In the length direction of the belt conveyor mechanism, the distance between the first belt 11 and the loading part 2 is smaller than the distance between the second belt 12 and the loading part 2, so as to form an avoidance gap 13 on the second side.

[0050] By arranging the first belt 11 and the second belt 12 in parallel, a stable support and conveying surface can be provided for the slag-blocking rod 4, ensuring that the slag-blocking rod 4 remains stable during conveying and will not tilt or fall. By making the distance between the first belt 11 and the feeding part 2 smaller than the distance between the second belt 12 and the feeding part 2, an avoidance gap 13 is naturally formed, which not only ensures the realization of the avoidance function, but also does not affect the conveying efficiency and conveying stability of the belt conveyor mechanism.

[0051] The belt conveyor mechanism comprises a first belt 11 and a second belt 12, which are arranged parallel to each other and extend along the conveying direction. The first belt 11 is installed on the first side of the belt conveyor mechanism, and the second belt 12 is installed on the second side. The upper surfaces of the two belts are on the same horizontal plane, forming the conveying surface of the slag-blocking rod 4. In the length direction of the belt conveyor mechanism, the distance between the end of the first belt 11 and the loading part 2 is set to be small, while the distance between the end of the second belt 12 and the loading part 2 is set to be large. Since the two belts are parallel and at different distances from the loading part 2, an avoidance gap 13 is naturally formed on the second side. During operation, the slag-blocking rod 4 is placed on both the first belt 11 and the second belt 12 and is conveyed to the loading position 51 with the synchronous rotation of the two belts. The first baffle block 14 and the second baffle block 27 extending to the avoidance gap 13 position the slag-blocking rod 4. After the clamping unit clamps the slag-blocking rod 4, it can be smoothly rotated out from the avoidance gap 13 on the second side, avoiding interference.

[0052] In one embodiment, the automatic feeding device for the slag-blocking rod includes a control unit, which is connected to a first driving member, a second driving member 23, a gripper 26, and a belt conveyor mechanism; sensors are provided at both the loading position 51 and the material picking position 52, and the sensors are connected to the control unit.

[0053] By setting up a control unit and connecting it to various power components and sensors, fully automatic control of the automatic feeding device is achieved. The control unit can receive signals transmitted by the sensors and coordinate the first drive component 23, the second drive component 23, the gripper 26, and the belt conveyor mechanism according to preset programs or real-time signals, ensuring that the actions of each component are orderly and precisely coordinated. The sensors at the loading position 51 and the material removal position 52 can detect the position status of the slag-blocking bar 4 in real time, such as whether the slag-blocking bar 4 has reached the loading position 51 and the material removal position 52, providing accurate feedback information to the control unit. This allows the control unit to adjust the actions of each component in a timely manner, achieving closed-loop control, improving the automation level of the automatic feeding device, enabling unattended operation of the slag-blocking bar 4 feeding, further reducing manual intervention and human error, and improving the accuracy, stability, and efficiency of the feeding process, thus meeting the needs of large-scale, continuous production in steel plants.

[0054] The automatic feeding device for the slag-blocking bar is equipped with a control unit. This control unit can be a control box or module including a PLC controller, relays, and other components. It is connected to the drive mechanisms of the first drive unit, the second drive unit 23, the gripper 26, and the drive motor of the belt conveyor via wires or wireless communication. It can send control commands to these components to control their start, stop, running speed, and running direction. Sensors, such as photoelectric sensors or proximity switches, are installed at both the loading position 51 and the unloading position 52 to detect status information such as whether the slag-blocking bar 4 is in position. These sensors are connected to the control unit via wires and can transmit the detected signals to the control unit in real time. During operation, the sensors continuously monitor the status of the loading position 51 and the unloading position 52. When the sensor at the loading position 51 detects the arrival of the slag-blocking bar 4, it transmits a signal to the control unit. The control unit then sends a command to stop the belt conveyor and simultaneously controls the gripper 26 to clamp the slag-blocking bar 4. Afterward, it controls the first and second drive units 23 to move, driving the clamping unit and the slag-blocking bar 4 to rotate. When the sensor at the material feeding position 52 detects the arrival of the slag-blocking rod 4, the control unit sends a command to control the gripper 26 to relax, and at the same time controls the feeding unit 3 to receive the slag-blocking rod 4. Then, it controls all components to reset, preparing for the next feeding cycle. Through the coordinated work of the control unit and the sensor, the entire feeding process is automated.

[0055] The working steps of the automatic slag-blocking bar feeding device are as follows: Step 1: The belt conveyor of the transport section 1 transports the slag-blocking rod 4 to the loading position 51. The first baffle block 14 and the second baffle block 27 work together to align and position the slag-blocking rod 4.

[0056] Step 2: The gripper 26 of the clamping unit holds the slag-blocking rod 4 tightly, while the receiving bracket 28 on the second material blocking block 27 abuts against the conical surface of the slag-blocking rod 4 to form a double fixation.

[0057] Step 3: The rotating feeder 21 of the feeding section 2 rotates around the center of the slewing bearing 22 under the drive of the first drive mechanism until it is aligned with the feeding end of the dispensing section 3.

[0058] Step 4: The second drive component 23 of the second drive mechanism drives the slider 25 to move through the lead screw 24 assembly. The slider 25 drives the gripper 26, the receiving bracket 28 and the slag-blocking rod 4 to move synchronously, pushing the slag-blocking rod 4 to the material picking position 52.

[0059] Step 5: The feeding part 3 picks up the material from the material picking position 52, the gripper 26 releases and disengages, and the slag-blocking rod 4 is fed.

[0060] Step 6: The second drive unit 23 drives the slider 25 through the lead screw 24 assembly, which in turn drives the gripper 26 and the receiving bracket 28 to retract to the initial position.

[0061] Step 7: The rotating loading rack 21 rotates around the center of the slewing bearing 22 under the drive of the first drive mechanism, and returns to the loading position 51, ready to enter the next loading cycle.

[0062] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.
