Description

Technical Field

[0001] This application relates to the field of galvanizing production lines, and in particular to a fully automated zinc-adding system. Background Technology

[0002] Hot-dip galvanizing, also known as hot-dip zinc plating, is an effective method of metal corrosion protection. It typically involves immersing rust-removed steel parts in molten zinc at temperatures above 500°C, causing a zinc layer to adhere to the surface of the steel parts and thus providing corrosion protection.

[0003] When galvanizing products, the products need to be galvanized in a furnace filled with molten zinc. During the galvanizing process, the molten zinc is continuously consumed. Insufficient molten zinc will result in the products not being adequately covered by the zinc, thus affecting the zinc layer thickness. To ensure the quality and effect of hot-dip galvanizing, an appropriate amount of zinc ingots needs to be added to the molten zinc to replenish it. However, directly adding zinc ingots to the molten zinc and allowing them to completely melt will cause the zinc content in the molten zinc to rise rapidly, affecting the fluidity and coating performance of the molten zinc, and consequently impacting the quality of the products to be galvanized.

[0004] The existing zinc-addition method involves using zinc ingots with pre-drilled receiving holes. During hot-dip galvanizing, the zinc ingots are typically hoisted manually using an electric hoist. The hoist, carrying the ingots, is then moved above the furnace via a control rail. The ingots are manually raised and lowered based on the zinc molten metal level in the furnace. Specifically, when the zinc molten metal level is below the low level line, the worker operates the electric hoist to immerse the ingot in the molten metal; when it is above the high level line, the worker operates the hoist to move the ingot away from the furnace and out of the molten metal. The temperature of the molten zinc is typically maintained above 500 degrees Celsius during melting, resulting in high ambient temperatures and the potential release of harmful gases. Furthermore, the zinc ingots used for melting are large in mass and volume, leading to a significant daily consumption of zinc ingots for hot-dip galvanizing and substantial workload for on-site workers. Summary of the Invention

[0005] To overcome the shortcomings of existing zinc-addition methods, this application provides a fully automatic zinc-addition system.

[0006] This application provides a fully automatic zinc-adding system, which adopts the following technical solution:

[0007] A fully automatic zinc feeding system includes a frame with a zinc ingot loading position, a zinc ingot unloading position, a zinc ingot flipping position, a zinc ingot hoisting position, and a zinc ingot melting position arranged sequentially along the feeding direction. The frame is equipped with a conveying mechanism for conveying zinc ingots from the zinc ingot loading position to the zinc ingot unloading position, a flipping mechanism for receiving zinc ingots at the zinc ingot unloading position and flipping the zinc ingots at the zinc ingot flipping position, a first sliding mechanism for driving the flipping mechanism back and forth between the zinc ingot unloading position and the zinc ingot hoisting position, a lifting mechanism for hoisting zinc ingots at the zinc ingot hoisting position and reciprocating up and down the zinc ingots at the zinc ingot melting position, a second sliding mechanism for driving the lifting mechanism back and forth between the zinc ingot hoisting position and the zinc ingot melting position, and a zinc melting mechanism located at the zinc ingot melting position for melting the zinc ingots.

[0008] The conveying mechanism includes a feeding track that extends along the feeding direction and passes through the zinc ingot loading position and the zinc ingot unloading position. The tilting mechanism includes a tilting base, a tilting bucket, and a tilting drive. The tilting base is connected to the first sliding mechanism. The tilting bucket is used to receive zinc ingots and is connected to the tilting drive. The tilting drive is mounted on the tilting base and is used to rotate the tilting bucket. The lifting mechanism is connected to the second sliding mechanism. The lifting mechanism includes a lifting drive and a lifting jaw connected to the lifting drive. The lifting drive is used to drive the lifting jaw to reciprocate vertically. The lifting jaw is used to penetrate the receiving hole of the zinc ingot.

[0009] By adopting the above technical solution, during zinc addition, an AGV forklift can place zinc ingots onto the feeding track. Multiple zinc ingots are placed orderly on the feeding track, which transports them to the unloading position so that they can be received by the tilting bucket. After the tilting bucket receives the zinc ingot, the feeding track stops transporting it, and the first sliding mechanism drives the tilting base away from the conveying mechanism. The tilting bucket then carries the zinc ingot away from the feeding track and to the tilting position. At the tilting position, the tilting drive rotates the tilting bucket, causing the zinc ingot to rotate. After rotation, the axis of the receiving hole on the zinc ingot changes from vertical to horizontal, facilitating subsequent clamping by the lifting claws. After tilting, the first sliding mechanism drives the tilting base towards the zinc ingot lifting position, allowing the tilting bucket to reach that position. At the zinc ingot hoisting position, the lifting drive mechanism lowers the hoisting jaws, which then insert two teeth into the receiving holes of the zinc ingot to hold it. Once the jaws have secured the ingot, the lifting drive mechanism raises them. After the ingot is raised to a certain height, the second sliding mechanism moves the lifting drive mechanism toward the zinc ingot melting position. At the melting position, the lifting drive mechanism can move the hoisting jaws into or away from the zinc melting mechanism.

[0010] In summary, through the coordination of the conveying mechanism, the tilting mechanism, the first sliding mechanism, the lifting mechanism, the second sliding mechanism, and the zinc melting mechanism, automatic hoisting, automatic transfer, and automatic melting of zinc ingots are achieved, greatly reducing the labor intensity of on-site workers.

[0011] Optionally, the frame is further provided with a guide mechanism located at the zinc ingot feeding position. The guide mechanism includes two limiting plates, which are disposed opposite to each other on both sides of the feeding track. Guide balls are rolled on the surfaces of the two limiting plates near the feeding track and are used to fit in contact with the zinc ingot.

[0012] By adopting the above technical solution, when the zinc ingot is placed on the feeding track, it may shift or tilt. If the position of the zinc ingot is not adjusted in time, it may fall off the feeding track or fail to enter the tilting hopper at the zinc ingot unloading position. The feeding track carries the zinc ingot through the guide mechanism located at the zinc ingot loading position. Two limiting plates guide the zinc ingot. Guide balls are set on the limiting plates so that they fit against the zinc ingot. As the zinc ingot moves toward the zinc ingot unloading position, the guide balls also roll, which can guide the zinc ingot and reduce friction during the guiding process.

[0013] Optionally, the frame is provided with a centering mechanism between the zinc ingot loading position and the zinc ingot unloading position. The centering mechanism includes a centering drive and a centering head. The centering head is connected to the centering drive and is used to fit into the receiving hole of the zinc ingot. The centering drive is used to drive the centering head to pass into the receiving hole of the zinc ingot.

[0014] By adopting the above technical solution, the zinc ingot may become skewed when it moves on the feeding track. A centering mechanism is set between the zinc ingot loading position and the zinc ingot unloading position. When the zinc ingot passes the centering mechanism, the centering drive unit drives the centering head to move into the receiving hole of the zinc ingot, which can correct the position of the zinc ingot so that the zinc ingot on the feeding track can move neatly toward the zinc ingot unloading position and smoothly enter the tipping hopper.

[0015] Optionally, the frame is provided with an air blowing mechanism for blowing away impurities on the surface of the zinc ingot between the zinc ingot loading position and the zinc ingot unloading position. The air blowing mechanism includes a nozzle support mounted on the frame and an air blowing nozzle mounted on the nozzle support. The nozzle of the air blowing nozzle is directed toward the zinc ingot.

[0016] By adopting the above technical solution, some dust or other impurities may adhere to the surface of the zinc ingot during transportation. These impurities may cause unevenness in the coating during subsequent hot-dip galvanizing. By setting up a blowing mechanism during the transportation of zinc ingots, the air nozzles can blow away the impurities adhering to the surface of the zinc ingots.

[0017] Optionally, each of the two teeth of the lifting jaws is provided with a wing plate, and a positioning cone pin is protruding on the wing plate. Two auxiliary lifting mechanisms are arranged opposite each other on both sides of the zinc ingot lifting position to assist the lifting jaws in opening. The auxiliary lifting mechanism includes a vertically arranged first support column, an opening cylinder that reciprocates along the axis of the first support column, and a sliding drive component for driving the opening cylinder to slide. The axis of the output shaft of the opening cylinder is horizontally arranged, and a positioning hole adapted to the positioning cone pin is opened at the end of the output shaft of the opening cylinder away from the first support column. The positioning cone pin is used to pass through the positioning hole.

[0018] By adopting the above technical solution, when the lifting mechanism lifts the zinc ingot at the zinc ingot lifting position, the lifting drive component drives the lifting jaws to descend. During the descent of the lifting jaws, the positioning cone pins set on the two jaw teeth are inserted into the positioning holes. The output shafts of the two opening cylinders move in the direction away from the lifting jaws. The two jaws of the lifting jaws open under the drive of the output shafts of the opening cylinders so that they can be subsequently passed into the receiving hole of the zinc ingot.

[0019] Optionally, a positioning mechanism is provided at the zinc ingot hoisting position, the positioning mechanism comprising:

[0020] A horizontal positioning mechanism includes a first positioning sensor for detecting the receiving hole of a zinc ingot in the horizontal direction. The first positioning sensor is also used to send the horizontal positioning result to a controller of a first sliding mechanism, which then closes the first sliding mechanism based on the horizontal positioning result.

[0021] A vertical positioning mechanism includes a second positioning sensor and a sensor connecting rod. The sensor connecting rod is vertically arranged, with one end connected to the opening cylinder and the other end connected to the second positioning sensor. The second positioning sensor is used to detect the position of the receiving hole of the zinc ingot when the opening cylinder reciprocates along the axial direction of the first support column, and sends the vertical positioning result to the controller of the sliding drive. The controller of the sliding drive shuts down the sliding drive based on the vertical positioning result.

[0022] By adopting the above technical solution, the first sliding mechanism drives the flipping mechanism carrying the zinc ingot to move toward the zinc ingot hoisting position. When the first positioning sensor detects the receiving hole of the zinc ingot, the first sliding mechanism stops driving the flipping mechanism. Simultaneously, as the hoisting mechanism and the opening cylinder descend together, the second positioning sensor also descends under the drive of the opening cylinder. When the second positioning sensor detects the receiving hole of the zinc ingot, it sends the vertical positioning result to the controller of the sliding drive component. The controller of the sliding drive component shuts down the sliding drive component, and the opening cylinder stops moving downwards. When the opening cylinder stops moving downwards, the hoisting jaws also stop moving downwards. At this time, the position of the clamping teeth of the hoisting jaws is flush with the position of the receiving hole of the zinc ingot.

[0023] Optionally, the tilting bucket includes a first opening for the zinc ingot to enter the tilting bucket, a second opening for the zinc ingot receiving hole to be exposed, a first support plate disposed relative to the first opening, a second support plate disposed relative to the second opening, a third support plate, and a fourth support plate disposed relative to the third support plate.

[0024] By adopting the above technical solution, the tilting bucket has a hexahedral structure. The zinc ingot enters the tilting bucket from the first opening and is lifted out of the tilting bucket by the lifting mechanism from the second opening. The first support plate, second support plate, third support plate and fourth support plate of the tilting bucket can support the zinc ingot when the tilting bucket is transporting and tilting the zinc ingot.

[0025] Optionally, the fourth support plate is provided with a clamping support and a clamping device. The clamping device includes a clamping cylinder hinged to the clamping support, a clamping shaft rotatably connected to the clamping support, a first connecting rod, a first connecting plate, a second connecting rod, and a clamping ball. One end of the first connecting rod is hinged to the output shaft of the clamping cylinder, and the other end is fixedly connected to the clamping shaft. One end of the first connecting plate is fixedly connected to the clamping shaft, and the other end is used to fit against the surface of the zinc ingot parallel to the first opening. One end of the second connecting rod is fixedly connected to the clamping shaft, and the other end is connected to the clamping ball. The fourth support plate has a clamping groove adapted to the clamping ball, and the clamping ball is used to pass into the clamping groove and abut against the zinc ingot.

[0026] By adopting the above technical solution, the first connecting plate can rotate under the drive of the clamping cylinder until it is in contact with the surface of the zinc ingot parallel to the first opening surface. This arrangement can clamp the zinc ingot when the tilting bucket carries the zinc ingot away from the feeding track, preventing the zinc ingot from slipping out of the tilting bucket due to friction during the transfer process. After the tilting bucket carries the zinc ingot away from the feeding track, the clamping balls can be inserted into the clamping groove under the drive of the clamping cylinder to abut against the zinc ingot. This arrangement can apply clamping force to the zinc ingot when the tilting bucket drives the zinc ingot to rotate.

[0027] Optionally, the flipping drive includes a flipping cylinder hinged to the flipping base, a rotating shaft support fixedly connected to the flipping base, a flipping shaft rotatably connected to the rotating shaft support, and a flipping connecting rod with one end hinged to the output shaft of the flipping cylinder and the other end fixedly connected to the flipping shaft. One end of the flipping shaft is fixedly connected to the first support plate.

[0028] By adopting the above technical solution, when the tilting drive drives the tilting bucket to rotate, the output shaft of the tilting cylinder drives the tilting connecting rod to rotate 90 degrees around the axis of the tilting shaft. The tilting shaft is also driven to rotate 90 degrees by the tilting connecting rod, and the tilting shaft in turn drives the tilting bucket to rotate 90 degrees around the axis of the tilting shaft.

[0029] Optionally, the zinc melting mechanism includes a pre-melting pot for containing molten zinc. The pre-melting pot is equipped with a level sensor for detecting the level of molten zinc in the pre-melting pot. The level sensor is used to send a level signal to the lifting drive, and the lifting drive controls the zinc ingot to rise or fall based on the level signal.

[0030] Optionally, the third support plate is provided with a conveying groove adapted to the feeding track, the conveying groove being used for the feeding track to convey the zinc ingot into the tipping bucket.

[0031] By adopting the above technical solution, the conveyor trough ensures that the third support plate will not interfere with the conveyor belt when the tilting bucket receives zinc ingots.

[0032] By adopting the above technical solution, when the lifting drive is above the zinc ingot melting position, the lifting drive can drive the lifting jaws to rise or fall according to the zinc liquid level in the pre-melting pot. When the liquid level sensor detects that the zinc liquid level is equal to or lower than the preset minimum zinc liquid level, the lifting drive drives the lifting jaws to fall, and the zinc ingot enters the pre-melting pot. When the liquid level sensor detects that the zinc liquid level is greater than or equal to the preset maximum zinc liquid level, the lifting drive stops falling and adding zinc until the liquid level is lower than the set value, and then continues to fall and add zinc. When it falls to the set lower limit position, it holds for a set time and then raises the lifting jaws to prepare to lift the next zinc ingot.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. Through the coordination of the conveying mechanism, the tilting mechanism, the first sliding mechanism, the lifting mechanism, the second sliding mechanism, and the zinc melting mechanism, the automatic hoisting, automatic transfer, and automatic melting of zinc ingots are realized, which greatly reduces the labor intensity of on-site workers.

[0035] 2. By installing a clamping device on the tilting bucket, the zinc ingot can be prevented from sliding out of the tilting bucket when the tilting bucket moves the zinc ingot away from the feeding track, and the zinc ingot can also be prevented from falling out of the tilting bucket when the tilting bucket moves the zinc ingot to rotate.

[0036] 3. By installing a liquid level sensor in the pre-melting pot, when the lifting drive is above the zinc ingot melting position, the lifting drive can drive the lifting jaws to rise or fall according to the zinc liquid level in the pre-melting pot. When the liquid level sensor detects that the zinc liquid level is equal to or lower than the preset minimum zinc liquid level, the lifting drive drives the lifting jaws to fall, and the zinc ingot enters the pre-melting pot. When the liquid level sensor detects that the zinc liquid level is greater than or equal to the preset maximum zinc liquid level, the lifting drive stops falling and adding zinc until the liquid level is lower than the set value, then continues to fall and add zinc. When it falls to the set lower limit position, it holds for a set time and then raises the lifting jaws to prepare to lift the next zinc ingot. Attached Figure Description

[0062] The present application will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the application and are not intended to limit the scope of the application.

[0063] This application discloses a fully automated zinc-adding system. (Refer to...) Figure 1 A fully automatic zinc feeding system includes a frame 1, which is sequentially arranged along the feeding direction as a zinc ingot loading position 01, a zinc ingot unloading position 02, a zinc ingot flipping position 03, a zinc ingot hoisting position 04, and a zinc ingot melting position 05. Further, the frame 1 is equipped with a conveying mechanism 2 for conveying zinc ingots 00 from the zinc ingot loading position 01 to the zinc ingot unloading position 02; a flipping mechanism 3 for receiving zinc ingots 00 at the zinc ingot unloading position 02 and flipping them at the zinc ingot flipping position 03; a first sliding mechanism 4 for driving the flipping mechanism 3 back and forth between the zinc ingot unloading position 02 and the zinc ingot hoisting position 04; a lifting mechanism 5 for hoisting zinc ingots 00 at the zinc ingot hoisting position 04 and reciprocating up and down the zinc ingots 00 at the zinc ingot melting position 05; a second sliding mechanism 6 for driving the lifting mechanism 5 back and forth between the zinc ingot hoisting position 04 and the zinc ingot melting position 05; and a zinc melting mechanism 7 located at the zinc ingot melting position 05 for melting the zinc ingots 00.

[0064] Reference Figure 1 and Figure 2 The conveying mechanism 2 includes a feeding track 21, which extends along the feeding direction and passes through the zinc ingot loading position 01 and the zinc ingot unloading position 02. In different embodiments, the feeding track 21 can have different structures, as long as it can transport multiple zinc ingots 00 from the zinc ingot loading position 01 to the zinc ingot unloading position 02. As an example, the feeding track 21 is a double-track belt conveyor. The conveyor belt of the double-track belt conveyor is used to receive and transport the zinc ingots 00.

[0065] Reference Figure 3 The tilting mechanism 3 includes a tilting base 31, a tilting bucket 32, and a tilting drive 33. The tilting base 31 is connected to the first sliding mechanism 4 and is used to drive the tilting drive 33 and the tilting bucket 32 ​​to slide along the feeding direction. The tilting drive 33 is mounted on the tilting base 31 and is used to rotate the tilting bucket 32. The tilting bucket 32 ​​is connected to the tilting drive 33 and is used to receive zinc ingots 00 and drive the zinc ingots 00 to rotate.

[0066] During the zinc feeding process, the tilting bucket 32 ​​undergoes both positional and angular changes. Specifically, when the feeding track 21 conveys zinc ingots 00 towards the zinc ingot unloading position 02, the tilting bucket 32 ​​is positioned on the zinc ingot unloading position 02, meaning it is above the feeding track 21. After the zinc ingot 00 enters the tilting bucket 32, the first sliding mechanism 4 drives the tilting base 31 to move, and the tilting bucket 32 ​​leaves the feeding track 21, reaching the zinc ingot tilting position 03. At the zinc ingot tilting position 03, the tilting drive 33 drives the tilting bucket 32 ​​to rotate, causing the zinc ingot 00 to rotate. After rotation, the axis of the receiving hole of the zinc ingot 00 changes from a vertical to a horizontal orientation, facilitating the subsequent clamping of the zinc ingot by the lifting claw 52. After the tilting bucket 32 ​​has completed rotating the zinc ingot 00, the first sliding mechanism 4 continues to drive the tilting base 31 to move, and the tilting bucket 32 ​​reaches the zinc ingot lifting position 04.

[0067] Reference Figure 2 and Figure 3 In different embodiments, the tilting bucket 32 ​​can have different structures, as long as it can receive the zinc ingot 00 at the zinc ingot unloading position 02 and ensure that the zinc ingot 00 does not fall out of the tilting bucket 32 ​​during rotation and tilting. As an example, the tilting bucket 32 ​​is a hexahedral structure, including a first opening surface 321 for the zinc ingot 00 to enter the tilting bucket 32, a second opening surface 322 for the receiving hole of the zinc ingot 00 to be exposed, a first support plate 323 set relative to the first opening surface 321, a second support plate 324 set relative to the second opening surface 322, a third support plate 325, and a fourth support plate 326 set relative to the third support plate 325. When the tilting bucket 32 ​​is located above the feeding track 21 waiting for the zinc ingot 00 to enter the tilting bucket 32, the first opening surface 321 and the first support plate 323 are set facing the feeding direction, and at this time the third support plate 325 is close to the conveyor belt of the double-track belt conveyor. In order to enable the double-track belt conveyor to transport zinc ingot 00 into the tilting bucket 32, the third support plate 325 is provided with two conveying grooves 3251 that are adapted to the conveyor belt of the double-track belt conveyor. The conveying grooves 3251 ensure that the third support plate 325 will not interfere with the conveyor belt when the tilting bucket 32 ​​receives zinc ingot 00.

[0068] Furthermore, when the tipping bucket 32 ​​moves the zinc ingot 00 away from the conveyor belt of the dual-track belt conveyor, friction will occur between the zinc ingot 00 and the conveyor belt. Although the first support plate 323, the second support plate 324, the third support plate 325, and the fourth support plate 326 can all support the zinc ingot 00 when the tipping bucket 32 ​​rotates, the zinc ingot 00 may still slip out from the first opening surface 321 or the second opening surface 322. Therefore, to prevent the zinc ingot 00 from falling out of the tipping bucket 32 ​​during transfer and tipping, refer to... Figure 4 and Figure 5Specifically, but not limitingly, a clamping device 35 is proposed, comprising a clamping cylinder 351, a clamping shaft 352, a first connecting rod 353, a first connecting plate 354, a second connecting rod 355, and clamping balls 356. A clamping support 34 is provided on the fourth support plate 326 of the tilting bucket 32. The clamping cylinder 351 is hinged to the clamping support 34. (See reference...) Figure 2 The clamping shaft 352 is rotatably connected to the clamping support 34. (Refer to...) Figure 3 One end of the first connecting rod 353 is hinged to the output shaft of the clamping cylinder 351, and the other end is fixedly connected to the clamping rotating shaft 352. (Refer to...) Figure 4 One end of the first connecting plate 354 is fixedly connected to the pressing shaft 352, and the other end is used to fit against the surface of the zinc ingot 00 parallel to the first opening surface 321. (Refer to...) Figure 5 One end of the second connecting rod 355 is fixedly connected to the clamping shaft 352, and the other end is connected to the clamping ball 356. The fourth support plate 326 has a clamping groove (not shown in the figure) adapted to the clamping ball 356, and the clamping ball 356 is used to pass into the clamping groove and abut against the zinc ingot 00. The projection of the axis of the first connecting plate 354 and the axis of the second connecting rod 355 onto the axial direction of the clamping shaft 352 does not coincide.

[0069] The clamping device 35 has three states: (Refer to...) Figure 2 When there is no zinc ingot 00 in the tilting bucket 32, the clamping device 35 is in its initial state. At this time, the first connecting plate 354 is not at the first opening surface 321, and the clamping ball 356 has not entered the clamping groove; refer to Figure 4 When the tipping bucket 32 ​​carries the zinc ingot 00 away from the conveyor belt of the double-track belt conveyor, the clamping device 35 is in its first state. At this time, the clamping cylinder 351 drives the first connecting rod 353 to move, the first connecting rod 353 drives the clamping shaft 352 to rotate, and the clamping shaft 352 drives the first connecting plate 354 and the second connecting rod 355 to rotate. The first connecting plate 354 rotates until it is in contact with the surface of the zinc ingot 00 parallel to the first opening surface 321. At this time, the clamping ball 356 is still not inserted into the clamping groove. With this setting, the first connecting plate 354 can clamp the zinc ingot 00 when the tipping bucket 32 ​​carries the zinc ingot 00 away from the feeding track 21, preventing the zinc ingot 00 from slipping out of the tipping bucket 32 ​​due to friction during the transfer process. At this time, the clamping ball 356 is not in contact with the zinc ingot 00 and will not apply pressure to the zinc ingot 00 vertically, thus increasing the friction between the zinc ingot 00 and the conveyor belt. (Refer to...) Figure 5After the tilting bucket 32 ​​carries the zinc ingot 00 away from the feeding track 21, before the tilting bucket 32 ​​tilts, the clamping device 35 is in the second state. At this time, the clamping cylinder 351 continues to drive the first connecting rod 353 to move, the first connecting rod 353 continues to drive the clamping shaft 352 to rotate, and the clamping shaft 352 continues to drive the first connecting plate 354 and the second connecting rod 355 to rotate. The clamping ball 356 can be inserted into the clamping groove and abut against the zinc ingot 00 under the drive of the clamping shaft 352. In this way, a clamping force can be applied to the zinc ingot 00 when the tilting bucket 32 ​​drives the zinc ingot 00 to rotate. After the tilting bucket 32 ​​has finished driving the zinc ingot 00 to rotate, the clamping device 35 can return to the first state or the initial state.

[0070] Reference Figure 3 and Figure 6 In different embodiments, the tilting drive 33 can have different structures, as long as it can drive the tilting bucket 32 ​​to rotate. As an example, the tilting drive 33 includes a tilting cylinder 331 hinged to the tilting base 31, a rotating shaft support 332 fixedly connected to the tilting base 31, a tilting rotating shaft 333 rotatably connected to the rotating shaft support 332, and a tilting connecting rod 334 with one end hinged to the output shaft of the tilting cylinder 331 and the other end fixedly connected to the tilting rotating shaft 333. One end of the tilting rotating shaft 333 is fixedly connected to the first support plate 323. (Refer to...) Figure 7 Specifically, when the tilting drive 33 drives the tilting bucket 32 ​​to rotate, the output shaft of the tilting cylinder 331 drives the tilting connecting rod 334 to rotate 90 degrees around the axis of the tilting shaft 333. The tilting shaft 333 is also driven to rotate 90 degrees by the tilting connecting rod 334, and the tilting shaft 333 in turn drives the tilting bucket 32 ​​to rotate 90 degrees.

[0071] In different embodiments, the first sliding mechanism 4 can have different structures, see reference. Figure 2 As an example, the first sliding mechanism 4 includes a first electric telescopic rod 41, a slide rail 42, and a pulley 43 mounted on the bottom of the tilting base 31. Both the first electric telescopic rod 41 and the slide rail 42 extend along the feeding direction. The first electric telescopic rod 41 is connected to the tilting base 31, and the pulley 43 is slidably connected to the slide rail 42. When the tilting base 31 needs to slide, the first electric telescopic rod 41 drives the tilting base 31 to slide, and the tilting base 31 slides along the slide rail 42.

[0072] Reference Figure 8 The lifting mechanism 5 is connected to the second sliding mechanism 6. The lifting mechanism 5 includes a lifting drive component 51 and a lifting jaw 52 connected to the lifting drive component 51. The lifting drive component 51 drives the lifting jaw 52 to reciprocate vertically. The lifting jaw 52 is used to insert into the receiving hole of the zinc ingot 00. The lifting drive component 51 can be an electric hoist, and the electric hoist is connected to the lifting jaw 52. (Refer to...) Figure 1The second sliding mechanism 6 is a linear motor installed above the conveying mechanism 2, the flipping mechanism 3, the first sliding mechanism 4, the zinc melting mechanism 7, and the auxiliary hoisting mechanism 12. The slide rail of the linear motor is set along the feeding direction. The mover of the linear motor is connected to the lifting drive component 51. An auxiliary pulley can also be installed on the lifting drive component 51. The auxiliary pulley is slidably connected to the slide rail of the linear motor.

[0073] Reference Figure 9 Each of the two teeth of the lifting gripper 52 is provided with a wing plate 521, and a positioning cone pin 522 is protruding on the wing plate 521. On both sides of the zinc ingot lifting position 04, there are two auxiliary lifting mechanisms 12 for assisting the lifting gripper 52 to open. The auxiliary lifting mechanism 12 includes a vertically arranged first support column 121, an opening cylinder 122 that slides back and forth along the axis of the first support column 121, and a sliding drive component 123 for driving the cylinder to slide. The axis of the output shaft of the opening cylinder 122 is horizontally arranged. The end of the output shaft of the opening cylinder 122 away from the first support column 121 is provided with a positioning hole 1211 that is adapted to the positioning cone pin 522. The positioning cone pin 522 is used to pass through the positioning hole 1211. When the lifting mechanism 5 lifts zinc ingot 00 at zinc ingot lifting position 04, the lifting drive component 51 drives the lifting jaws 52 to descend. During the descent of the lifting jaws 52, the positioning cone pins 522 set on the two jaw teeth are inserted into the positioning holes 1211. The output shafts of the two opening cylinders 122 move away from the lifting jaws 52. The two jaws of the lifting jaws 52 open under the drive of the output shafts of the opening cylinders 122 so that they can be inserted into the receiving holes of the zinc ingot 00 to hold the zinc ingot 00.

[0074] Furthermore, in order to accurately hoist the zinc ingot 00, a positioning mechanism 11 is also provided on the zinc ingot hoisting position 04. The positioning mechanism 11 includes a horizontal positioning mechanism 111 and a vertical positioning mechanism 112. The horizontal positioning mechanism 111 includes a first positioning sensor 1111 for detecting the receiving hole of the zinc ingot 00 in the horizontal direction. The first positioning sensor 1111 sends the horizontal positioning result to the controller of the first sliding mechanism 4. In this embodiment, the controller of the first sliding mechanism 4 is the controller of the first electric telescopic rod 41. The controller of the first electric telescopic rod 41 closes the first electric telescopic rod 41 based on the horizontal positioning result. When the first electric telescopic rod 41 is closed, it will stay at the position it was in when it was closed. The vertical positioning mechanism 112 includes a second positioning sensor 1121 and a sensor connecting rod 1122. The sensor connecting rod 1122 is vertically arranged, with one end connected to the opening cylinder 122 and the other end connected to the second positioning sensor 1121. When the opening cylinder 122 reciprocates along the first support column 121, the second positioning sensor 1121 detects the position of the receiving hole of the zinc ingot 00 and sends the vertical positioning result to the controller of the sliding drive 123. The controller of the sliding drive 123 closes the sliding drive 123 based on the vertical positioning result. The sliding drive 123 can be a linear motor. The slide rail of the linear motor is arranged on the first support column 121 along the axial direction of the first support column 121, and the mover of the linear motor is fixedly connected to the opening cylinder 122. The sliding drive component 123 may also include a second electric telescopic rod, a second slide rail, and a second pulley mounted on the bottom of the opening cylinder 122. The second electric telescopic rod and the second slide rail are arranged along the axial direction of the first support column 121, and the second pulley is slidably connected to the second slide rail.

[0075] The first sliding mechanism 4 drives the flipping mechanism 3, which carries the zinc ingot 00, to move toward the zinc ingot hoisting position 04. When the first positioning sensor 1111 detects the receiving hole of the zinc ingot 00, the first sliding mechanism 4 stops driving the flipping mechanism 3. Simultaneously, as the lifting mechanism 5 and the opening cylinder 122 descend together, the second positioning sensor 1121 also descends under the drive of the opening cylinder 122. When the second positioning sensor 1121 detects the receiving hole of the zinc ingot 00, it sends the vertical positioning result to the controller of the sliding drive component 123. The controller of the sliding drive component 123 shuts down the sliding drive component 123, and the opening cylinder 122 stops moving downwards. When the opening cylinder 122 stops moving downwards, the lifting jaw 52 also stops moving downwards. At this time, the position of the jaw teeth of the lifting jaw 52 is flush with the position of the receiving hole of the zinc ingot 00.

[0076] Furthermore, the zinc melting mechanism 7 includes a pre-melting pot 71 for containing molten zinc. A level sensor (not shown in the figure) is installed in the pre-melting pot 71 to detect the level of the molten zinc within it. The level sensor sends a level signal to the lifting drive 51, which controls the zinc ingot 00 to rise or fall based on the level signal. Specifically, when the level sensor detects that the molten zinc level is equal to or lower than a preset minimum molten zinc level, the lifting drive 51 drives the lifting gripper 52 to descend, and the zinc ingot 00 enters the pre-melting pot 71. When the level sensor detects that the molten zinc level is greater than or equal to a preset maximum molten zinc level, the lifting drive 51 stops descending to add zinc until the level is lower than the set value, then continues descending to add zinc. When the level reaches the set lower limit, it is held for a set time before the lifting gripper 52 is raised, ready to lift the next zinc ingot 00.

[0077] Reference Figure 10 The frame 1 is also equipped with a guide mechanism 8 located at the zinc ingot loading position 01. The guide mechanism 8 includes two limiting plates 81, which are arranged opposite each other on both sides of the feeding track 21. Guide balls 82 are rolled on the surfaces of the two limiting plates 81 near the feeding track 21, and the guide balls 82 are used to fit against the zinc ingot 00. When the zinc ingot 00 is placed on the feeding track 21, some displacement or tilting may occur. If the position of the zinc ingot 00 is not adjusted in time, the zinc ingot 00 may fall on the feeding track 21 or fail to enter the tilting hopper 32 at the zinc ingot unloading position 02. The feeding track 21 drives the zinc ingot 00 to pass through the guide mechanism 8 located at the zinc ingot loading position 01. The two limit plates 81 can guide the zinc ingot 00. Guide balls 82 are set on the limit plates 81 so that the guide balls 82 are in contact with the zinc ingot 00. When the zinc ingot 00 moves toward the zinc ingot unloading position 02, the guide balls 82 also roll, which can guide the zinc ingot 00 and reduce the friction during the guiding process.

[0078] A centering mechanism 9 is provided between the zinc ingot loading position 01 and the zinc ingot unloading position 02 on the frame 1. The centering mechanism 9 includes a centering drive member 91 and a centering head 92. The centering head 92 is connected to the centering drive member 91 and is used to adapt to the receiving hole of the zinc ingot 00. The centering drive member 91 is used to drive the centering head 92 to pass into the receiving hole of the zinc ingot 00. Specifically, the receiving holes of the zinc ingot 00 are usually arranged symmetrically in twos. Therefore, the centering mechanism 9 in this embodiment is also arranged in pairs, with the two centering mechanisms 9 symmetrically arranged on both sides of the feeding track 21. Further, the centering mechanism 9 of this application is provided in one set at the end of the feeding track 21 near the zinc ingot loading position 01 and in another set at the end of the feeding track 21 near the zinc ingot unloading position 02. As an example, the centering drive member 91 can be an electric push rod, and the centering head 92 is installed at the end of the electric push rod. A centering mechanism 9 is set at one end of the feeding track 21 near the zinc ingot loading position 01, and a centering mechanism 9 is set at the other end of the feeding track 21 near the zinc ingot unloading position 02. When the zinc ingot 00 passes the centering mechanism 9, the centering drive 91 drives the centering head 92 to enter the receiving hole of the zinc ingot 00, which can correct the position of the zinc ingot 00 so that the zinc ingot 00 on the feeding track 21 can move neatly toward the zinc ingot unloading position 02 and smoothly enter the tilting bucket 32.

[0079] Reference Figure 11 The frame 1 is provided with an air blowing mechanism 10 for blowing away impurities on the surface of the zinc ingot 00 between the zinc ingot loading position 01 and the zinc ingot unloading position 02. The air blowing mechanism 10 includes a nozzle support 101 provided on the frame 1 and an air blowing nozzle 102 provided on the nozzle support 101. The nozzle of the air blowing nozzle 102 is set towards the zinc ingot 00.

[0080] The implementation principle of this application embodiment is as follows: When adding zinc, the zinc ingot 00 is placed on the feeding track 21 by an AGV forklift. After passing through the guide mechanism 8, centering mechanism 9, air blowing mechanism 10, and centering mechanism 9, the zinc ingot 00 is conveyed to the zinc ingot unloading position 02. At the zinc ingot unloading position 02, the zinc ingot 00 is received by the tilting bucket 32. After the tilting bucket 32 ​​receives the zinc ingot 00, the feeding track 21 stops conveying the zinc ingot 00. Specifically, the centering mechanism 9 can perform a centering operation on the zinc ingot 00 when the feeding track 21 stops. After the zinc ingot 00 enters the tilting bucket 32, the first sliding mechanism 4 drives the tilting base 31 away from the conveying mechanism 2. The tilting bucket 32 ​​drives the zinc ingot 00 away from the feeding track 21 and to the zinc ingot tilting position 03. During this process, the first connecting plate 354 is driven by the pressing cylinder 351 to the first opening surface 321 to fit against the zinc ingot 00, preventing the zinc ingot 00 from sliding out of the tilting bucket 32 ​​during the transfer process. After the tilting bucket 32 ​​reaches the zinc ingot tilting position 03, the clamping ball 356, driven by the clamping cylinder 351, abuts against the zinc ingot 00. The tilting drive 33 rotates the tilting bucket 32, which in turn drives the zinc ingot 00 to rotate. After rotation, the axis of the receiving hole of the zinc ingot 00 changes from a vertical position to a horizontal position, so as to facilitate the subsequent clamping of the zinc ingot 00 by the lifting claw 52. After the tilting is completed, the clamping device returns to the initial state or the first state, and the first sliding mechanism 4 continues to drive the tilting base 31 so that the tilting bucket 32 ​​reaches the zinc ingot lifting position 04. At zinc ingot hoisting position 04, lifting drive component 51 drives hoisting jaw 52 to descend, positioning cone pin 522 enters positioning hole 1211, opening cylinder 122 drives hoisting jaw 52 to open, hoisting jaw 52 and opening cylinder 122 descend together until the clamping teeth of hoisting jaw 52 are flush with the receiving hole of zinc ingot 00, opening cylinder 122 drives hoisting jaw 52 to close, the clamping teeth of hoisting jaw 52 clamp zinc ingot 00 through the receiving hole of zinc ingot 00, after hoisting jaw 52 has clamped zinc ingot 00, lifting drive component 51 drives hoisting jaw 52 to rise. After the lifting claw 52 lifts the zinc ingot 00 to a certain height, the second sliding mechanism 6 drives the lifting drive component 51 to move toward the zinc ingot melting position 05. At the zinc ingot melting position 05, the lifting drive component 51 drives the lifting claw 52 to enter or move away from the pre-melting pot 71 according to the zinc liquid level in the pre-melting pot 71.

[0081] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
