TECHNICAL FIELD
[0001] The present application relates to a slagging arm telescopic mechanism of a slagging device. BACKGROUND
[0002] In the traditional aluminum processing smelting process, manual slagging is generally used. However, due to the high-temperature and high-heat environment in front of the aluminum melting furnace door and the presence of harmful gases, the overall working environment is poor, which exceeds the range that the body of the worker can withstand. Therefore, in recent years, it is more and more difficult to find workers. The existing slagging machines on the market generally include a moving mechanism, a mechanical arm mounted on the moving mechanism, and the mechanical arm can perform up-down tilting, axial telescoping, and horizontal rotating movements. During work, the mechanical arm first telescopes axially to extend the front-end slagging claw into the deepest part of the aluminum melting furnace, then controls the mechanical arm to lower, so that the slagging claw contacts the slag, then controls the mechanical arm to retract the slagging claw, so as to remove the slag. In the process of retracting the mechanical arm, in order to remove the slag from the liquid metal and ensure that the slag can float above the liquid surface, the front end of the mechanical arm needs to be tilted upward to gradually pull out the slagging claw, so that the slag is removed upward by the slagging claw. This process is very slow, and the slagging efficiency is too low. Especially when the slagging claw is in the deepest part of the aluminum melting furnace, it needs to wait for the process of falling into the slag. The closer the aluminum melting furnace is to the deepest part, the higher the temperature is. The mechanical arm and the slagging claw will absorb a large amount of heat. These heat will be conducted to the rear end through the mechanical arm, which will adversely affect the motor and control components at the rear end. Therefore, it is necessary to minimize the time of the slagging claw staying in the deepest part of the aluminum melting furnace and the liquid metal, so as to minimize the impact of heat and improve the slagging efficiency as much as possible. SUMMARY
[0003] The purpose of the present application is to provide a slagging arm telescopic mechanism of a slagging device. By utilizing the change of the center of gravity during the movement of the mechanical arm, the tilting angle is automatically adjusted by the compression spring, so that the front end of the mechanical arm automatically tilts downward during the extension of the mechanical arm into the aluminum melting furnace, and the front end of the mechanical arm automatically tilts upward during the retraction of the mechanical arm, so as to realize the function of removing the slag from below the liquid surface. Therefore, the time of the slagging claw staying in the deepest part of the aluminum melting furnace and the liquid metal can be minimized, the slagging efficiency can be improved, the energy consumption of the driving mechanism for driving the tilting movement of the mechanical arm can be reduced, and the thermal impact on the mechanical arm and the components at the rear end can be reduced.
[0004] The technical solution of the present application is as follows: a slagging arm telescopic mechanism of a slagging device includes: a rack; a mechanical arm assembled on the rack and axially movable relative to the rack, the front end of the mechanical arm being provided with a slagging claw; a plurality of guide rollers in rolling contact with the upper surface and the lower surface of the mechanical arm respectively to guide the mechanical arm, each guide roller including a roller seat and a roller rotatably assembled on the roller seat; The guide spring mechanism includes multiple guide spring units that are arranged one-to-one with the guide rollers. Each guide spring unit includes a guide sleeve and a spring. One end of the guide sleeve is connected to the roller seat of the corresponding guide roller, and the other end is vertically connected to the frame. The spring provides the guide roller with an elastic force toward the robotic arm to squeeze the robotic arm and achieve guide fit. When the robotic arm moves axially relative to the frame, the pitch angle of the robotic arm relative to the frame will change due to the change in the center of gravity.
[0005] The beneficial effects of this technical solution are as follows: When the slag removal arm telescopic mechanism of the slag removal device is in use, as the robotic arm carrying the slag removal claw extends into the aluminum melting furnace, the center of gravity of the robotic arm, supported by multiple guide rollers and guide spring units, moves forward. This increases the compression of the springs near the front end and decreases the compression of the springs near the rear end. The robotic arm gradually tilts relative to the frame, causing the slag removal claw to automatically move closer to the slag, thereby reducing the running time and energy consumption of the subsequent pitch drive mechanism. When the slag removal claw contacts the slag, the robotic arm retracts to the rear end. The compression of the springs at the rear end gradually increases, while the compression of the springs at the front end decreases. The front end of the robotic arm gradually lifts up, thereby using the slag removal claw to lift the slag from the molten metal to the surface. Therefore, this application utilizes the change in the center of gravity during the movement of the robotic arm to automatically compress the spring and achieve pitch angle adjustment. Thus, during the extension of the robotic arm into the aluminum melting furnace, the front end of the robotic arm automatically swings downward, and during the retraction of the robotic arm, the front end of the robotic arm automatically tilts upward to achieve the function of scraping slag from below the liquid surface. This minimizes the time that the slag scraping claw spends in the deepest part of the aluminum melting furnace and in the molten metal, improves the efficiency of slag scraping, reduces the energy consumption of the drive mechanism that drives the pitching motion of the robotic arm, and reduces the thermal impact on the robotic arm and its rear components.
[0006] Based on the above solution, further improvements are made as follows: A telescopic drive mechanism is also included to drive the robotic arm to move axially. This mechanism includes a drive motor and a driving sprocket driven by the motor. Driven sprockets are symmetrically arranged on both sides of the driving sprocket. A chain is also included, with both ends connected to the two ends of the upper surface of the robotic arm. The drive motor and driving sprocket are mounted on the frame. The driven sprockets are rotatably mounted on sprocket seats. The two sprocket seats are perpendicularly connected to the frame via guide spring units. The springs in the guide spring units corresponding to the sprocket seats provide elastic forces to the driven sprockets towards the pressing chain and the robotic arm. With the guide spring units on the driven sprockets, the driven sprockets can still maintain good contact and engagement with the chain during the pitching and swinging of the robotic arm relative to the frame.
[0007] Based on the above scheme, the following improvements are made: the guide sleeve includes an inner sleeve and an outer sleeve that are nested together. The ends of the inner sleeve and the outer sleeve that are close to each other are stopped by a ring boss. With the help of a spring, the deformation can be buffered and the deformation can be controlled to be limited to a set displacement range.
[0008] Based on the above scheme, the following improvements are made: the frame includes a rectangular sleeve, the robotic arm extends and retracts within the rectangular sleeve, and each guide spring unit is vertically connected to the top and bottom plates of the rectangular sleeve, respectively.
[0009] Based on the above scheme, further improvements are made as follows: at least two guide spring units are connected to the top plate and bottom plate of the rectangular sleeve, and each guide spring unit is arranged symmetrically along the length of the rectangular sleeve.
[0010] Based on the above scheme, the following improvements are made: the frame includes an L-shaped mounting plate, the mounting plate includes a vertical plate and a horizontal plate located at the upper end of the vertical plate, the drive motor and the drive sprocket are mounted on the mounting plate, and the guide spring units corresponding to the two sprocket seats are respectively vertically connected to the horizontal plate of the mounting plate.
[0011] Based on the above scheme, the following improvements are made: the upper surface of the robotic arm is provided with guide rails extending along its length direction, two guide rails are symmetrically arranged along the width direction of the robotic arm, the upper surface of the guide rails rolls with the rollers, and the two guide rails form a chain groove for accommodating the chain, the depth of the chain groove is greater than the thickness of the chain, and the driven sprocket extends into the chain groove.

[0016] The features and performance of the present invention will be further described in detail below with reference to embodiments.
[0017] A specific embodiment of the slag-removing arm telescopic mechanism of the slag-removing device of the present invention: as follows Figures 1-6 As shown, the slag removal device's slag removal arm telescopic mechanism includes a mobile platform 1, a mechanical arm 4, a rectangular sleeve 8, a rotary drive mechanism 2, a pitch drive mechanism 3, a telescopic drive mechanism 7, a guide roller 5, and a guide spring unit 6.
[0018] The frame includes a rectangular sleeve 8, comprising a top plate 81, a bottom plate 82, and side plates. A robotic arm 4 is mounted on the frame and can move axially relative to it. A scraping claw is installed at the front end of the robotic arm 4. Multiple guide rollers 5, including roller seats 51 and rollers 52, respectively guide and roll in cooperation with the upper and lower surfaces of the robotic arm 4 to guide it. The rollers 52 are rotatably mounted on the roller seats 51. The guide spring mechanism includes multiple guide spring units 6, each corresponding to one of the guide rollers 5. Each guide spring unit 6 includes a guide sleeve 62 and a spring 61. One end of the guide sleeve 62 is connected to the roller seat 51 of the corresponding guide roller 5, and the other end is perpendicularly connected to the frame. The spring 61 provides an elastic force to the guide roller 5 towards the robotic arm 4, compressing the robotic arm 4 to achieve a guiding fit. When the robotic arm 4 moves axially relative to the frame, its pitch angle relative to the frame changes due to the change in its center of gravity.
[0019] The telescopic drive mechanism 7 is used to drive the robotic arm 4 to move axially. It includes a drive motor and a drive sprocket 71 driven by the drive sprocket 71. Driven sprockets 72 are symmetrically arranged on both sides of the drive sprocket 71. It also includes a chain 73, with both ends of the chain 73 connected to the two ends of the upper surface of the robotic arm 4. The drive motor and the drive sprocket 71 are mounted on the frame. The driven sprockets 72 are rotatably mounted on sprocket seats 710. The two sprocket seats 710 are perpendicularly connected to the frame through guide spring units 6. The springs 61 of the guide spring units 6 corresponding to the sprocket seats 710 provide the driven sprockets 72 with an elastic force that compresses the chain 73 and the robotic arm 4. After the driven sprockets 72 are equipped with guide spring units 6, the driven sprockets 72 can still maintain good contact and cooperation with the chain 73 during the pitching and swinging of the robotic arm 4 relative to the frame. The guide sleeve 62 includes an inner sleeve 621 and an outer sleeve 622 that are nested together. The ends of the inner sleeve 621 and the outer sleeve 622 that are close to each other are stopped by an annular boss 623. With the help of the spring 61, the deformation can be buffered and the deformation can be controlled to be limited to a set displacement range. The frame includes a rectangular sleeve 8. The robotic arm 4 extends and retracts in the rectangular sleeve 8. Each guide spring unit 6 is perpendicularly connected to the top plate 81 and the bottom plate 82 of the rectangular sleeve 8, respectively. There are at least two guide spring units 6 connected to the top plate 81 and the bottom plate 82 of the rectangular sleeve 8. Each guide spring unit 6 is symmetrically arranged along the length of the rectangular sleeve 8. The frame includes an L-shaped mounting plate 83. The mounting plate 83 includes a vertical plate and a horizontal plate located at the upper end of the vertical plate. The drive motor and the drive sprocket 71 are mounted on the mounting plate 83. The guide spring units 6 corresponding to the two sprocket seats 710 are perpendicularly connected to the horizontal plate of the mounting plate 83, respectively. The upper surface of the robotic arm 4 is provided with guide rails 41 extending along its length direction. Two guide rails 41 are symmetrically arranged along the width direction of the robotic arm 4. The upper surface of the guide rails 41 rolls with the roller 52. The two guide rails 41 form a chain groove 42 for accommodating the chain 73. The depth of the chain groove 42 is greater than the thickness of the chain 73. The driven sprocket 72 extends into the chain groove 42.
[0020] When the slag removal device's slag removal arm extension mechanism is in use, as the robotic arm 4, carrying the slag removal claw, extends into the aluminum melting furnace, the center of gravity of the robotic arm 4, supported by multiple guide rollers 5 and guide spring units 6, shifts forward. This causes the compression of the spring 61 near the front end of the guide spring unit 6 to increase, while the compression of the spring 61 near the rear end decreases. The robotic arm 4 gradually tilts relative to the frame, causing the slag removal claw to automatically move closer to the slag, thereby reducing the running time and energy consumption of the subsequent pitch drive mechanism 3. When the slag removal claw contacts the slag, the robotic arm 4 retracts to the rear end. The compression of the spring 61 at the rear end gradually increases, while the compression of the spring 61 at the front end decreases. The front end of the robotic arm 4 gradually lifts up, thereby using the slag removal claw to lift the slag from the molten metal to the surface. Therefore, this application utilizes the change in the center of gravity during the movement of the robotic arm 4 to automatically compress the spring 61 to achieve pitch angle adjustment. Thus, during the extension of the robotic arm 4 into the aluminum melting furnace, the front end of the robotic arm 4 automatically swings downward, and during the retraction of the robotic arm 4, the front end of the robotic arm 4 automatically tilts upward to achieve the function of scraping slag from below the liquid surface. This minimizes the time that the slag scraping claw spends in the deepest part of the aluminum melting furnace and in the molten metal, improves the efficiency of slag scraping, reduces the energy consumption of the drive mechanism that drives the pitching motion of the robotic arm 4, and reduces the thermal impact on the robotic arm 4 and its rear components.
