Description

Technical Field

[0001] This invention relates to the field of molding and feeding equipment technology, specifically to an automatic feeding device and process for molding and processing magnesia-carbon bricks. Background Technology

[0002] Magnesia-carbon bricks are non-burning carbon composite refractory materials made from high-melting-point alkaline oxide magnesium oxide and high-melting-point carbon materials that are difficult to be wetted by slag, with the addition of various non-oxide additives and carbonaceous binders. They need to be pressurized during the molding process. Magnesia-carbon bricks are mainly used for the lining of converters, AC electric arc furnaces, DC electric arc furnaces, and slag lines of ladles. Before the molding of magnesia-carbon bricks, the material to be molded needs to be automatically fed. Generally, during feeding, a robotic arm moves the hopper below the feeding point. After the hopper is full of material, the robotic arm moves the hopper above the mold and opens the hopper to distribute the material into the mold cavity. Since the outlet of the hopper is usually located in the center of the mold cavity, when the material falls through the hopper opening, it will form a cone-shaped accumulation pattern in the mold cavity, which is high in the middle and low around the edges. It is not easy to evenly cover the entire interior of the mold cavity. This can easily lead to excessive pressure in the center of the accumulated material and insufficient compaction around the edges during subsequent extrusion molding. This can easily cause deformation or cracking of the brick blank during subsequent molding, affecting the feeding efficiency and subsequent coverage efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic feeding device and process for the molding and processing of magnesia-carbon bricks, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to an automatic feeding device for the molding and processing of magnesia-carbon bricks, comprising two main bodies, a connecting plate fixedly connected to the bottom of the two main bodies, and a sensor fixedly connected to the end of the two main bodies away from the connecting plate. It also includes: A connecting mechanism is installed on the side wall of the main body to prevent uneven distribution of materials in the mold cavity during feeding. An auxiliary mechanism is installed on the side wall of the connecting mechanism to prevent material from accumulating during feeding.

[0005] Furthermore, the main body includes: The feeding assembly is installed between the two main bodies; The rotating component is installed inside the feeding component.

[0006] Furthermore, the connecting mechanism includes two toothed frames installed inside the feeding assembly, with a central plate fixedly connected between the two toothed frames. The connecting mechanism also includes: A shaking component is installed at the bottom of the center plate; The swing assembly is mounted on the side wall of the wobbling assembly.

[0007] Furthermore, the auxiliary mechanism includes several L-plates disposed on the sidewall of the swaying component, and the auxiliary mechanism also includes: The elastic component is installed on top of several L-plates.

[0008] Furthermore, the feeding assembly includes a hopper that is slidably connected between the two main bodies, and electric push rods are fixedly connected to the left and right sides of the hopper. The output end of the electric push rods is rotatably connected to two connecting shafts. A gate is rotatably connected between the two connecting shafts; The rotating assembly includes a second connecting plate fixedly connected to the side of the gate plate near the connecting shaft, and a rotating rod fixedly connected between the two second connecting plates. Gears are fixedly connected to the outer surface of the rotating rod located inside the hopper.

[0009] Furthermore, the gear carrier is meshed between the two gears, and the center plate is fixedly connected between the two gear carriers; The wobbling assembly includes two spring-loaded telescopic rods rotatably connected to the bottom of the center plate, with a movable plate rotatably connected to the end of the spring-loaded telescopic rods away from the center plate.

[0010] Furthermore, rotating plates are rotatably connected to both the left and right sides of the movable plate, and the side walls of the rotating plates are provided with several inclined grooves. Several bending springs are fixedly connected between the two rotating plates, and the bending springs are distributed at equal intervals. Two L-bars are slidably connected to the side wall of one of the rotating plates; The two L-bars are slidably connected, and the sidewalls of the L-bars are rotatably connected to inclined plates.

[0011] Furthermore, several L-plates are arranged in a circular array of four, with each group of L-plates fixedly connected to the outer surface of the movable plate; Each set of L-plates has a corrugated plate 1 fixedly connected to its top, a tension spring fixedly connected to its top, and a corrugated plate 2 fixedly connected to the end of each of the four tension springs furthest from the L-plate.

[0012] Furthermore, a spring ball is fixedly connected to the top of the second wave plate, and a fixing rod is fixedly connected to the side wall of the second wave plate. The outer surface of the fixing rod is in contact with the side wall of the inclined plate. When the tension spring is in the initial position, it will be in a bent state between the L plate and the second wave plate and accumulate elastic potential energy for reset.

[0013] Furthermore, a method for using an automatic feeding device for magnesia-carbon brick molding and processing, the method comprising the following steps: S1: Connection and installation: First, install the hopper between the two main bodies and fix the hopper between the two main bodies using the fixing device. Then, connect this device to the external robotic arm through the connecting plate. S2: Moving material: When it is necessary to feed the material before molding, the robotic arm moves the hopper to below the discharge port of the feeding point and picks up the material of a predetermined weight. Then, the robotic arm moves the hopper carrying the material to above the mold cavity of the molding equipment. S3: Start feeding: After the sensor positions the material, the electric push rod is activated. When the electric push rod is working, it will push the gate through the two connecting shafts and cause the gate to drive the connecting plate 2 to rotate. At this time, the two gates will open at the bottom of the hopper, and the material will be transported into the mold cavity when the gates are open, thus completing the feeding purpose of magnesia-carbon brick molding.

[0014] The present invention has the following beneficial effects: 1. This invention, by guiding the material with a rotating plate and swinging the rotating plate driven by a spring telescopic rod, can reduce the cone-shaped accumulation of material in the mold cavity when it falls, which is high in the middle and low around the edges. At the same time, it can also make the material evenly cover the inside of the mold cavity. This can further reduce the situation where the accumulated material is subjected to excessive pressure in the center and insufficient pressure around the edges during subsequent extrusion molding, which leads to deformation and cracking of the material after being compressed. This can improve the feeding efficiency of the material during feeding and the covering efficiency of the material in the mold cavity during feeding.

[0015] 2. In this invention, when the spring telescopic rod drives the rotating plate to continue swinging, the rotating plate will swing upwards against the direction of material falling. At this time, when the side wall of the rotating plate contacts the material, it can reduce the swing amplitude of the rotating plate driven by the spring telescopic rod to swing to both sides. This can reduce the situation where the material is excessively scattered and some material splashes outside the mold cavity due to the excessive rotation amplitude of the rotating plate driven by the spring telescopic rod during the fall. This can reduce the waste of material during the swing of the rotating plate driven by the spring telescopic rod, ensure the integrity and accuracy of the material during the feeding process, and improve the feeding efficiency.

[0016] 3. In this invention, when the second wave plate is shaking, the second wave plate will drive multiple spring balls at the top to shake when the material falls. The shaking of the second wave plate and multiple spring balls can reduce the compression of the falling space between the rotating plate and the hopper caused by the shaking of the rotating plate driven by the spring telescopic rod when the material falls, which may lead to material blockage or pulse feeding. This ensures the continuity of the feeding process while ensuring the stability of the feeding process and improves the feeding efficiency.

[0017] 4. In this invention, when there is a small amount of material in the hopper after the two rotating plates are reset, the material will drive the movable plate through the rotating plates, causing the movable plate to rotate at the bottom of the spring telescopic rod. At this time, the movable plate and the rotating plate at the bottom of the two spring telescopic rods will be in an inclined state. The inclination of the two movable plates and the rotating plates on both sides can ensure that the material inside the hopper continues to fall without being blocked by the rotating plates after reset, thereby reducing the situation of material residue during the feeding process and further improving the stability and feeding efficiency of continuous feeding.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1 - Figure 10 As shown, the present invention is an automatic feeding device for magnesia-carbon brick molding and processing, comprising two main bodies 1, with a connecting plate 101 fixedly connected to the bottom of the two main bodies 1, and a sensor 102 fixedly connected to the end of the two main bodies 1 away from the connecting plate 101, and further comprising: The connecting mechanism 2 is installed on the side wall of the main body 1 to prevent uneven distribution of materials in the mold cavity during feeding. Auxiliary mechanism 3 is installed on the side wall of connecting mechanism 2 to prevent material accumulation during feeding.

[0024] Entity 1 includes: Feeding component 11 is installed between the two main bodies 1; Rotating component 12 is installed inside the feeding component 11.

[0025] The connecting mechanism 2 includes two toothed frames 201 installed inside the feeding assembly 11, and a center plate 202 is fixedly connected between the two toothed frames 201. The connecting mechanism 2 also includes: Shaking component 21 is installed at the bottom of center plate 202; The swing assembly 22 is mounted on the side wall of the swaying assembly 21.

[0026] The auxiliary mechanism 3 includes a plurality of L-plates 301 disposed on the side wall of the swaying assembly 21, and the auxiliary mechanism 3 further includes: The elastic component 31 is installed on top of several L-plates 301.

[0027] The feeding assembly 11 includes a hopper 111 that is slidably connected between two main bodies 1. Electric push rods 112 are fixedly connected to the left and right sides of the hopper 111. The output end of the electric push rods 112 is rotatably connected to two connecting shafts. A gate 113 is rotatably connected between the two connecting shafts; The rotating assembly 12 includes a second connecting plate 121 fixedly connected to the side of the gate 113 near the connecting shaft, and a rotating rod 122 fixedly connected between the two connecting plates 121. Gears are fixedly connected to the outer surface of the rotating rod 122 inside the hopper 111. First, the hopper 111 is installed between the two main bodies 1 and fixed between the two main bodies 1 by a fixing device. Then, this device is connected to the external robotic arm through the connecting plate 101.

[0028] The gear frame 201 is meshed between two gears, and the center plate 202 is fixedly connected between the two gear frames 201; The swaying assembly 21 includes two spring telescopic rods 211 rotatably connected to the bottom of the center plate 202. The end of the spring telescopic rod 211 away from the center plate 202 is rotatably connected to a movable plate 212. When the gear rotates, it will drive the two gear frames 201 and the center plate 202 between the two gear frames 201 to slide downward. When the gear frames 201 and the center plate 202 slide downward, the center plate 202 will drive the spring telescopic rods 211, the movable plate 212 and the rotating plate 213 to slide downward and extend out of the outlet of the hopper 111.

[0029] The movable plate 212 is rotatably connected to the left and right sides of the rotating plate 213, and the side wall of the rotating plate 213 is provided with several inclined grooves. Several bending springs are fixedly connected between the two rotating plates 213, and the bending springs are distributed at equal intervals. Two L-shaped rods 221 are slidably connected to the side wall of one of the rotating plates 213; The two L-bars 221 are slidably connected, and an inclined plate 222 is rotatably connected to the side wall of the L-bars 221. When the two L-bars 221 drive the inclined plate 222 to slide relative to each other, the two L-bars 221 will exhibit a certain shape when the material falls. Figure 9 When the material is tilted, the tilting plate 222 will guide the falling material.

[0030] Several L-plates 301 are arranged in a circular array of four in a group, and each group of L-plates 301 is fixedly connected to the outer surface of the movable plate 212. Each set of L-plates 301 has a corrugated plate 311 fixedly connected to its top. A tension spring is also fixedly connected to the top of the L-plate 301. A corrugated plate 312 is fixedly connected to the end of each of the four tension springs away from the L-plate 301. When the fixed rod 313 is pushed, it will cause the corrugated plate 312 to rotate on the top of the corrugated plate 311. At this time, the corrugated plate 312 will slide against the top of the corrugated plate 311 during the rotation, causing the corrugated plate 312 to sway up and down.

[0031] A spring ball is fixedly connected to the top of the wave plate 312, and a fixing rod 313 is fixedly connected to the side wall of the wave plate 312. The outer surface of the fixing rod 313 is in contact with the side wall of the inclined plate 222. When the tension spring is in the initial position, it will be in a bent state between the L plate 301 and the wave plate 312 and accumulate elastic potential energy for reset.

[0032] A method for using an automatic feeding device for magnesia-carbon brick molding and processing, the method comprising the following steps: S1: Connection and installation: First, install the hopper 111 between the two main bodies 1 and fix the hopper 111 between the two main bodies 1 using the fixing device. Then, connect this device to the external robotic arm through the connecting plate 101. S2: Moving and picking up materials: When it is necessary to feed materials before molding, the robotic arm moves the hopper 111 to below the discharge port of the feeding point and picks up the predetermined weight of materials. Then, the robotic arm moves the hopper 111 carrying the materials to above the mold cavity of the molding equipment. S3: Start feeding: After being positioned by sensor 102, start electric push rod 112. When electric push rod 112 is working, it will push gate 113 through two connecting shafts and cause gate 113 to drive connecting plate 121 to rotate. At this time, the two gates 113 will open at the bottom of hopper 111. At the same time, the material can be transported into the mold cavity when the gates 113 are open, thus completing the feeding purpose of magnesium carbon brick molding.

[0033] In use, the hopper 111 is first installed between the two main bodies 1 and fixed between the two main bodies 1 by a fixing device. Then, the device is connected to the external robotic arm through the connecting plate 101. When the material needs to be fed before molding, the robotic arm moves the hopper 111 to the outlet of the feeding point and picks up the material of a predetermined weight. Then, the robotic arm moves the hopper 111 carrying the material to the mold cavity of the molding equipment. After being positioned by the sensor 102, the electric push rod 112 is activated. When the electric push rod 112 is working, it will push the gate 113 through the two connecting shafts and make the gate 113 drive the connecting plate 121 to rotate. At this time, the two gates 113 will open at the bottom of the hopper 111. At the same time, the material can be transported into the mold cavity when the gates 113 are open, thus completing the feeding purpose when molding magnesia-carbon bricks.

[0034] When the gate 113 drives the connecting plate 121 to rotate and open, the rotation of the connecting plate 121 will drive the rotating rod 122 and the gear on the surface of the rotating rod 122 to rotate. When the gear rotates, it will drive the two gear frames 201 and the center plate 202 between the two gear frames 201 to slide downward. When the gear frames 201 and the center plate 202 slide downward, the center plate 202 will drive the spring telescopic rod 211, the movable plate 212 and the rotating plate 213 to slide downward and extend outside the outlet of the hopper 111. Then, when the material falls, the material will flow and impact the rotating plates 213 on both sides of the movable plate 212. At this time, the rotating plates 213 on both sides of the movable plate 212 will rotate relative to each other when the material flows, presenting a... Figure 9 As shown in the diagram, when the two rotating plates 213 rotate relative to each other on the side wall of the movable plate 212, the rotated plate 213 guides the falling direction of the material and forces the center of the falling material to be forcibly broken and dispersed laterally. At the same time, when the material falls on the surface of the rotated plate 213, the spring telescopic rod 211 drives the rotated plate 213 to swing back and forth around the junction between the spring telescopic rod 211 and the center plate 202. Thus, by guiding the material through the rotating plate 213 and swinging the rotating plate 213 driven by the spring telescopic rod 211, the conical accumulation of material with a high center and low periphery in the mold cavity can be reduced when the material falls. At the same time, the material can be evenly covered inside the mold cavity. This can further reduce the situation where the center of the accumulated material is subjected to excessive pressure while the periphery is not compacted enough during subsequent extrusion molding, resulting in deformation and cracking of the material after being compressed. This can improve the feeding efficiency of the material during feeding and the covering efficiency of the material in the mold cavity during feeding.

[0035] When the falling material causes the spring telescopic rod 211 to swing the movable plate 212 and the rotated plate 213, the swinging of the two movable plates 212 will cause the two L-bars 221 to slide back and forth relative to each other as the rotating plate 213 swings. When the two L-bars 221 drive the inclined plate 222 to slide relative to each other, the two L-bars 221 will exhibit the following characteristics when the material falls: Figure 9 In the tilted state, the tilting plate 222 guides the falling material. Then, when the spring telescopic rod 211 drives the rotating plate 213, causing the two L-bars 221 to slide away from each other, the tilting plate 222 pushes the falling material as the L-bars 221 slide. At this time, the top area of ​​the tilting plate 222 rotates to a state approximately horizontal with the L-bars 221 due to the material's obstruction. The sidewalls of the tilting plate 222 then face the direction of material descent. Simultaneously, as the spring telescopic rod 211 drives the rotating plate 213 to continue swinging, the rotating plate 213... This will cause an upward swing against the direction of material descent. At this time, when the side wall of the rotating plate 213 contacts the material, it can reduce the swing amplitude of the rotating plate 213 driven by the spring telescopic rod 211 to swing to both sides. This can reduce the situation where the material is excessively scattered and some material splashes outside the mold cavity due to the excessive rotation amplitude of the rotating plate 213 driven by the spring telescopic rod 211 during descent. This can reduce the waste of material during the swing of the rotating plate 213 driven by the spring telescopic rod 211, ensure the integrity and accuracy of the material during the feeding process, and improve the feeding efficiency.

[0036] When the gear frame 201 drives the spring telescopic rod 211, movable plate 212, and rotating plate 213 to slide downwards via the center plate 202, the downward sliding of the rotating plate 213 will drive the L-rod 221 and inclined plate 222 to slide downwards. When the inclined plate 222 slides downwards, the side of the bottom area of ​​the inclined plate 222 will separate from the fixed rod 313. When the inclined plate 222 separates from the fixed rod 313, the wave plate 312 will drive the fixed rod 313 to rotate and reset under the restoring potential energy of the multiple tension springs at the bottom. At this time, the fixed rod 313 will contact the middle area of ​​the inclined plate 222 after it has slid downwards. Then, when the reciprocating motion of the two L-rods 221 drives the inclined plate 222 to slide synchronously, the reciprocating sliding of the inclined plate 222 will affect the side of the fixed rod 313. The wall is pushed intermittently. When the fixed rod 313 is pushed, it will drive the second wave plate 312 to rotate on the top of the first wave plate 311. At this time, the second wave plate 312 will slide with the top of the first wave plate 311 during the rotation and make the second wave plate 312 swing up and down. When the second wave plate 312 is swinging, it will drive the multiple spring balls on the top to swing when the material falls. The swinging of the second wave plate 312 and the multiple spring balls can reduce the compression of the falling space between the rotating plate 213 and the hopper 111 caused by the swinging of the spring telescopic rod 211 when the material falls, which may lead to material blockage or pulse feeding. This ensures the continuity of feeding while ensuring the stability of feeding and improves feeding efficiency.

[0037] As the material inside the hopper 111 gradually decreases, the weight of the material on the rotating plate 213 decreases. At this time, the two rotating plates 213 will reset under the potential energy release of the multiple bending springs at the bottom. When the two rotating plates 213 reset and there is less material in the hopper 111, the material will drive the movable plate 212 through the rotating plate 213, causing the movable plate 212 to rotate at the bottom of the spring telescopic rod 211. At this time, the movable plate 212 and the rotating plate 213 at the bottom of the two spring telescopic rods 211 will be in an inclined state. The inclination of the two movable plates 212 and the two rotating plates 213 on both sides can ensure that the material inside the hopper 111 continues to fall without being blocked by the rotating plate 213 after reset, thereby reducing the situation of material residue during the feeding process and further improving the stability and feeding efficiency of continuous feeding.

When the electric push rod (112) is working, it will push the gate (113) through the two connecting shafts and make the gate (113) drive the connecting plate (121) to rotate. At this time, the two gates (113) will open at the bottom of the hopper (111). At the same time, the material will be transported into the mold cavity when the gate (113) is opened, thus completing the feeding purpose of magnesium carbon brick molding.
