Description

Technical Field

[0001] The present invention relates to the technical field of powder feeding, and particularly relates to an automatic feeding line for rare earth metal powder. Background Art

[0002] In the rare earth metal electrolysis process, rare earth metals need to be mixed in a certain ratio and then added to the electrolysis furnace for electrolysis. The materials added to the electrolysis furnace are in powder form; during the production process, metal powders are automatically added to a mixer in a certain ratio for mixing, and after being filled into barrels according to a specific weight, the mixed materials are then manually poured into a feeder according to experience or sucked into the feeder by a vacuum feeding machine and then transported to the feeder, and finally added to the electrolysis furnace through the feeder.

[0003] However, during the process of adding the mixed materials to the feeder in the above manner, a large amount of dust will fly, which is likely to cause waste of raw materials and pollute the working environment; moreover, the feeding time is relatively long, increasing the working intensity of the staff. Summary of the Invention

[0004] In view of this, the present invention provides an automatic feeding line for rare earth metal powder to solve the problems that a large amount of dust will fly during the process of adding the mixed materials to the feeder in the existing feeding method, which is likely to cause waste of raw materials and pollute the working environment, and the feeding time is relatively long, and the working intensity of the staff is large.

[0005] The present invention provides an automatic feeding line for rare earth metal powder, including:

[0006] A feeder for adding the mixed materials to the electrolysis furnace;

[0007] A feeding mechanism arranged above the feeder, and the feeding mechanism includes:

[0008] A bracket;

[0009] A lifting assembly slidably arranged in the vertical direction on the bracket;

[0010] A clamping assembly rotatably connected to the side wall of the lifting assembly by a rotating assembly and used for clamping a barrel filled with materials;

[0011] A material pouring assembly is arranged on the top end surface of the clamping assembly, and the material pouring assembly includes a main mounting frame arranged on the clamping assembly, and the main mounting frame is provided with a sealed material guide cylinder, and a sealing member is provided on the inner wall of one end of the sealed material guide cylinder facing the barrel, and the end of the sealed material guide cylinder away from the barrel is arranged as a material guide port, and the material guide port is used to be plugged into the feeding end of the feeder, and the sealed material guide cylinder is driven by a telescopic member to move in a vertical direction, and the sealed material guide cylinder has a first state in which it is sleeved on the outside of the barrel opening, and a second state in which it is separated from the barrel opening; the sealed material guide cylinder is provided with a valve.

[0012] The automatic feeding line for rare earth metal powder according to the present invention has at least the following beneficial effects:

[0013] By rotating the clamping assembly to connect to the side wall of the lifting assembly, and setting the pouring assembly at the clamping end of the clamping assembly, when the material needs to be added to the feeder, first the barrel containing the material is transported to the bottom of the clamping end of the clamping assembly, at which time the opening of the barrel is in an open state; then the clamping assembly descends to clamp the barrel, and then the telescopic member is started to drive the sealing guide barrel to descend and sleeve the outside of the barrel opening, at which time the sealing member fills and seals between the inner wall of the sealing guide barrel and the outer wall of the barrel opening; then the lifting assembly drives the barrel, the clamping assembly and the pouring assembly to rise, and then rotates 180 degrees so that the guide port faces downward, and then rotates During the rotation process, because the valve is in a closed state and the inner wall of the sealed material guide cylinder and the outer wall of the barrel opening are filled and sealed, the material will not spill out; then the material guide port is driven down and plugged into the feeding end of the feeder. At this time, the gap between the outer side of the material guide port and the inner side of the feeding end of the feeder is extremely small, and the material cannot pass through the gap.

[0072] The following combines Figures 1 to 20 , to describe the embodiments of the present invention.

[0073] like Figures 1 to 5 as well as Figures 7 to 9 As shown, an automatic feeding line for rare earth metal powders provided according to an embodiment of the present invention comprises a feeder 100 and a feeding mechanism 300, wherein the feeder 100 is used to feed the proportioned and mixed materials into the electrolytic furnace 200; the feeding mechanism 300 is arranged above the feeder 100, and the feeding mechanism 300 comprises a bracket 310, wherein the bracket 310 is provided with a lifting assembly 320 slidingly arranged in the vertical direction, and the side wall of the lifting assembly 320 is rotatably connected with a clamping assembly 330, and the clamping assembly 330 is driven to rotate by a rotating assembly, and the clamping assembly 330 is used to clamp a barrel 340 filled with materials; the top surface of the clamping assembly 330 is provided with a pouring assembly 350, and the The material pouring assembly 350 includes a mounting main frame 351 arranged on the clamping assembly 330, and the mounting main frame 351 is provided with a sealing material guide cylinder 352, and the inner wall of the sealing material guide cylinder 352 at one end facing the barrel 340 is provided with a sealing member 3521, and the end of the sealing material guide cylinder 352 away from the barrel 340 is provided with a material guide port 3522, and the material guide port 3522 is used to be plugged into the feeding end of the feeder 100, and the sealing material guide cylinder 352 is driven by a telescopic member to move in a vertical direction, and the sealing material guide cylinder 352 has a first state in which it is sleeved on the outer side of the opening of the barrel 340, and a second state in which it is separated from the opening of the barrel 340; the sealing material guide cylinder 352 is provided with a valve 354.

[0074] In this embodiment, the automatic feeding line rotatably connects the clamping assembly 330 to the side wall of the lifting assembly 320, and arranges the pouring assembly 350 at the clamping end of the clamping assembly 330. When adding materials to the feeding machine 100, first, the material bucket 340 filled with materials is conveyed to directly below the clamping end of the clamping assembly 330. At this time, the opening of the material bucket 340 is in an open state; then the clamping assembly 330 descends to clamp the material bucket 340, and then the telescopic member is started to drive the sealing guide cylinder 352 to descend and sleeve outside the opening of the material bucket 340. At this time, the sealing member 3521 is filled and sealed between the inner wall of the sealing guide cylinder 352 and the outer wall of the opening of the material bucket 340; then the lifting assembly 320 drives the material bucket 340, the clamping assembly 330 and the pouring assembly 350 to rise, and then rotates 180 degrees so that the material guide port 3522 faces downward. During the rotation process, because the valve 354 is in a closed state, and the space between the inner wall of the sealing guide cylinder 352 and the outer wall of the opening of the material bucket 340 is filled and sealed, the materials will not spill out from the material guide port 3522; then drive the material guide port 3522 to descend and insert it into the feeding end of the feeding machine 100. At this time, the gap between the outside of the material guide port 3522 and the inside of the feeding end of the feeding machine 100 is extremely small, and the materials cannot pass through this gap. During the process of opening the valve 354 to quickly add the materials in the material bucket 340 into the feeding machine 100 under the action of gravity, it is ensured that there will be no dust flying, which will neither cause waste of raw materials nor pollute the working environment. At the same time, the entire feeding process has a high degree of automation, high replenishment efficiency, and reduces the working intensity of the staff.

[0075] It should be noted that the materials in this embodiment refer to rare earth metal powders. Of course, in specific applications, they can also be common metal powders.

[0076] It should be noted that during the process of opening the valve 354 to add materials into the feeding machine 100, because the material bucket 340 is in a vertical state, the materials in the material bucket 340 can quickly enter the feeding machine 100 through the sealing guide cylinder 352 under the action of gravity.

[0077] It should be noted that after the materials in the material bucket 340 are added into the feeding machine 100 to complete the feeding, first close the valve 354, then start the lifting assembly 320 to drive the material guide port 3522 to rise and disengage from the feeding end of the feeding machine 100. Then drive the material bucket 340, the clamping assembly 330 and the pouring assembly 350 to rotate 180 degrees, and then lower the material bucket 340, the clamping assembly 330 and the pouring assembly 350 together to a set position. Then start the lifting member to switch the sealing guide cylinder 352 from the first state to the second state, and then remove the clamping force applied by the clamping assembly 330 to the material bucket 340, so as to replace the empty material bucket 340 with another material bucket 340 filled with materials.

[0078] In specific applications, in order to ensure the reliability of clamping the material bucket 340, anti-slip patterns are provided at the positions on the outer sidewall of the material bucket 340 for clamping by the clamping assembly 330.

[0079] In order to enable the materials in the material bucket 340 to quickly and smoothly pass through the sealed material guiding cylinder 352 into the feeding machine 100 under the action of gravity, as Figure 8 shown, specifically, the material guiding port 3522 is set in a straight cylinder shape, the part of the sealed material guiding cylinder 352 relatively close to the material bucket 340 is set in a funnel shape, and the end of the sealed material guiding cylinder 352 facing the material bucket 340 is the large-diameter end.

[0080] Specifically, an annular groove is recessed in the inner wall of the sealed material guiding cylinder 352 at the position corresponding to the seal 3521, and the seal 3521 is fitted in the annular groove.

[0081] Specifically, the valve 354 is set as a pneumatic slide gate valve.

[0082] As Figure 8 and Figure 9 shown, specifically, the installation main frame 351 is provided with a through hole 3511 penetrating in the vertical direction, and the sealed material guiding cylinder 352 can slide vertically through the through hole 3511.

[0083] As Figure 7 shown, specifically, the telescopic member includes two cylinders 353, and the two cylinders 353 are symmetrically arranged about the center line of the sealed material guiding cylinder 352, so that the forces at all positions of the cross-section of the sealed material guiding cylinder 352 perpendicular to the vertical direction are more uniform, thereby ensuring the sealing effect at the connection between the sealed material guiding cylinder 352 in the first state and the opening of the material bucket 340.

[0084] In some embodiments, a seal part 122 that can be inflated is provided on the inner wall of the feeding end of the feeding machine 100; after driving the material guiding port 3522 to descend and insert into the feeding end of the feeding machine 100, the seal part 122 operates to inflate and expand, filling and sealing between the outside of the material guiding port 3522 and the inside of the feeding end of the feeding machine 100. During the process of opening the valve 354 to add the materials in the material bucket 340 into the feeding machine 100, it is ensured that the materials will not leak from the connection between the material guiding port 3522 and the feeding end of the feeding machine 100 to the outside and cause dust flying.

[0085] It should be noted that after adding the materials in the material bucket 340 into the feeding machine 100 to complete the feeding and closing the valve 354, the seal part 122 can deflate, so that there is a gap between the seal part 122 and the outside of the material guiding port 3522, so as to raise the material guiding port 3522 and separate it from the feeding end of the feeding machine 100.

[0086] As Figure 3As shown, in some embodiments, the lifting assembly 320 includes a lifting main frame 321 and a lifting electric cylinder 322. The lifting main frame 321 is slidably arranged on the bracket 310, and the clamping assembly 330 is rotatably connected to the side wall of the lifting main frame 321; the lifting electric cylinder 322 is arranged at the lower end of the bracket 310, and the piston end of the lifting electric cylinder 322 is connected to the bottom end of the lifting main frame 321. In the process of adding materials to the feeder 100, by controlling the extension and contraction of the piston end of the lifting electric cylinder 322, the clamping assembly 330 and the pouring assembly 350 can be accurately driven to smoothly lift to the required height position together with the lifting main frame 321. The whole structure is compact and the feeding operation is convenient.

[0087] like Figures 3 to 6 As shown, specifically, a mounting platform 334 is provided on the side of the lifting main frame 321 away from the clamping assembly 330, and a hydraulic station 410 is provided on the mounting platform 334; the rotating assembly includes a rotating seat 420 and a first gear rack swing cylinder 430, the rotating seat 420 is rotatably connected to the lifting main frame 321 toward the side of the clamping assembly 330 through a rotating shaft 421, the clamping assembly 330 is connected to the rotating seat 420, the first gear rack swing cylinder 430 is provided on the mounting platform 334, the first gear rack swing cylinder 430 is connected to the hydraulic station 410, and the end of the rotating shaft 421 away from the rotating seat 420 extends to the outside of the lifting main frame 321 and is connected to the first gear rack swing cylinder 430. By setting the hydraulic station 410 on the mounting platform 334, the hydraulic station 410 and the first gear rack swing cylinder 430 can be lifted and lowered synchronously with the lifting main frame 321, ensuring that the positional relationship between the hydraulic station 410 and the first gear rack swing cylinder 430 will not change during the lifting process, thereby simplifying the connecting pipeline between the hydraulic station 410 and the first gear rack swing cylinder 430 and stably supplying oil for the operation of the first gear rack swing cylinder 430; at the same time, by driving the rotating shaft 421 to rotate through the first gear rack swing cylinder 430, the rotating seat 420, the clamping assembly 330 and the pouring assembly 350 can be driven to rotate smoothly, thereby facilitating the accurate addition of materials into the feeder 100.

[0088] like Figure 3As shown, specifically, the bracket 310 includes two spaced-apart struts 311. A crossbeam 312 is connected between the tops of the two struts 311. Concave chutes 3111 are provided on the mutually facing sides of the two struts 311. Lifting pulleys are provided on the side of the lifting main frame 321 facing the struts 311, and the lifting pulleys are rollingly arranged in the chutes 3111. The two struts 311 slidably support both sides of the lifting main frame 321. The lifting main frame 321 reduces the friction between the lifting main frame 321 and the struts 311 by the rolling cooperation of the lifting pulleys and the chutes 3111, so that on the basis of using the more environmentally friendly jacking electric cylinder 322 as the power source, the clamping assembly 330 and the tipping assembly 350 are driven to smoothly lift and lower to the required height position together with the lifting main frame 321. At the same time, the two struts 311 are connected by the crossbeam 312 to increase the structural strength of the entire bracket 310.

[0089] To increase the rolling contact area between the lifting main frame 321 and the struts 311, more specifically, four lifting pulleys are provided on each side of the lifting main frame 321 facing each strut 311.

[0090] As Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown in

[0091] As Figure 10 andFigure 11 As shown, specifically, the first semi-circular clamping jaw 332 is rotatably arranged on the clamping main frame 331 through the active connecting shaft 335, and the second semi-circular clamping jaw 333 is rotatably arranged on the clamping main frame 331 through the driven connecting shaft 336; the driving assembly includes a second gear-rack swing oil cylinder 440, a main gear 441 and a driven gear 442. The second gear-rack swing oil cylinder 440 is connected to the hydraulic station 410, the second gear-rack swing oil cylinder 440 is connected to the active connecting shaft 335, the main gear 441 is coaxially arranged on the active connecting shaft 335, the driven gear 442 is coaxially arranged on the driven connecting shaft 336, and the driven gear 442 meshes with the main gear 441. By using the second gear-rack swing oil cylinder 440 as the power source to drive the main gear 441 to rotate forward or backward, and through the meshing relationship between the main gear 441 and the driven gear 442, the first semi-circular clamping jaw 332 and the second semi-circular clamping jaw 333 are accurately driven to rotate synchronously and approach or move away from each other, and by using the incompressible property of the oil, the fastening of the clamped bucket 340 is ensured, effectively avoiding the bucket 340 falling off when driving the bucket 340 filled with materials to flip 180 degrees; at the same time, during the lifting process, the positional relationship between the second gear-rack swing oil cylinder 440 and the hydraulic station 410 will not change, so as to stably supply oil for the operation of the second gear-rack swing oil cylinder 440 on the basis of simplifying the connecting pipeline between the hydraulic station 410 and the second gear-rack swing oil cylinder 440; especially effectively avoiding the connecting pipeline between the hydraulic station 410 and the second gear-rack swing oil cylinder 440 from being stretched or compressed, resulting in insufficient oil supply and insufficient clamping force on the bucket 340.

[0092] Specifically, the installation main frame 351 is connected to the clamping main frame 331.

[0093] In specific applications, the first semi-circular clamping jaw 332 and the second semi-circular clamping jaw 333 have the same structure, that is, the first semi-circular clamping jaw 332 and the second semi-circular clamping jaw 333 are mirror-symmetrically arranged, and the main gear 441 and the driven gear 442 use the same gear, so as to drive the first semi-circular clamping jaw 332 and the second semi-circular clamping jaw 333 to rotate synchronously and approach or move away from each other.

[0094] Specifically, a main connecting arm 337 is arranged between the first semi-circular clamping jaw 332 and the active connecting shaft 335, and the first semi-circular clamping jaw 332 is detachably connected to the main connecting arm 337 through the first connecting pin shaft 3371; it is convenient to disassemble and assemble the first semi-circular clamping jaw 332, thereby reducing the maintenance difficulty and maintenance cost.

[0095] Such as Figure 10 and Figure 11As shown, specifically, a slave connecting arm 338 is provided between the second semi-circular clamping jaw 333 and the driven connecting shaft 336, and the second semi-circular clamping jaw 333 is detachably connected to the slave connecting arm 338 through a second connecting pin shaft 3381; this facilitates the disassembly and assembly of the second semi-circular clamping jaw 333, thereby reducing the maintenance difficulty and maintenance cost.

[0096] As Figure 1 and Figures 3 to 5As shown, in some embodiments, the automatic feeding line further includes a horizontally arranged slide rail 510 that connects the material bucket storage area and the empty bucket placement area. The material bucket storage area is used to place the material buckets 340 filled with materials, and the empty bucket placement area is used to place the empty material buckets 340. The feeding machine 100 is arranged between the material bucket storage area and the empty bucket placement area. The bottom end of the bracket 310 is rotatably arranged on the main frame 520 and is driven to rotate by a rotating mechanism. The main frame 520 is slidably arranged on the slide rail 510 and is driven to move horizontally by a horizontal driving mechanism. When it is necessary to add materials to the feeding machine 100, the horizontal driving mechanism drives the entire feeding mechanism 300 to move towards the material bucket storage area until the clamping end of the clamping assembly 330 is directly above the material bucket 340 filled with materials. Subsequently, the clamping assembly 330 descends to clamp the material bucket 340 filled with materials. Then, the telescopic member is activated to drive the sealing material guiding cylinder 352 to descend and sleeve outside the opening of the material bucket 340. At this time, the seal 3521 is filled and sealed between the inner wall of the sealing material guiding cylinder 352 and the outer wall of the opening of the material bucket 340. Then, the lifting assembly 320 drives the material bucket 340, the clamping assembly 330, and the pouring assembly 350 to rise, and then rotates 180 degrees so that the material guiding port 3522 faces downward. During the rotation process, since the valve 354 is in the closed state and the space between the inner wall of the sealing material guiding cylinder 352 and the outer wall of the opening of the material bucket 340 is filled and sealed, the materials will not spill out. Subsequently, the horizontal moving mechanism drives the feeding mechanism 300 to move away from the material bucket storage area until the material guiding port 3522 is directly above the feeding end of the feeding machine 100. Then, the material guiding port 3522 is driven to descend and inserted into the feeding end of the feeding machine 100. At this time, the gap between the outside of the material guiding port 3522 and the inside of the feeding end of the feeding machine 100 is extremely small, and the materials cannot pass through this gap. When the valve 354 is opened and the materials in the material bucket 340 are quickly added to the feeding machine 100 under the action of gravity, it is ensured that no dust will fly, neither causing waste of raw materials nor polluting the working environment. After the materials in the material bucket 340 are added to the feeding machine 100 to complete the feeding, the valve 354 is closed, and then the lifting assembly 320 is activated to drive the material guiding port 3522 to rise and disengage from the feeding end of the feeding machine 100. Subsequently, the material bucket 340, the clamping assembly 330, and the pouring assembly 350 are driven to rotate 180 degrees, and then the feeding mechanism 300 is driven to move towards the empty bucket placement area until it reaches the idle station. Then, the rotating mechanism drives the feeding mechanism 300 to rotate around the vertical axis until the material bucket 340 is directly above the idle station, and then the empty material bucket 340 is lowered and placed at the idle station. It realizes separating the placement area of the material bucket 340 filled with materials from the placement area of the empty material bucket 340, automatically clamping the material bucket 340 filled with materials at the material bucket storage area, automatically adding the materials in the material bucket 340 to the feeding machine 100, and finally automatically transferring the empty material bucket 340 and placing it in the empty bucket placement area. The entire process has a high degree of automation.

[0097] AsFigures 12 to 14 As shown, specifically, an external gear type crossed roller bearing 521 is provided at the top end of the main frame 520. A rotating flat plate 360 is coaxially rotatably provided at the top end of the external gear type crossed roller bearing 521. The bracket 310 is provided on the rotating flat plate 360. The rotating mechanism includes a rotating gear 531 and a rotating motor 532. The rotating gear 531 is provided at the bottom end of the rotating flat plate 360 and meshes with the outside of the external gear type crossed roller bearing 521. The rotating motor 532 is provided at the top end of the rotating flat plate 360. The output end of the rotating motor 532 extends outside the bottom end of the rotating flat plate 360 and is connected to the rotating gear 531. When it is necessary to drive the feeding mechanism 300 to rotate about the vertical axis, the rotating motor 532 drives the rotating gear 531 to rotate. At this time, since the external gear type crossed roller bearing 521 is fixed to the main frame 520, the rotating gear 531 can rotate circumferentially relative to the external gear type crossed roller bearing 521, so that the rotating motor 532 rotates together with the rotating flat plate 360, realizing a stable drive for the feeding mechanism 300 to rotate.

[0098] As Figure 3 shown, specifically, the lifting electric cylinder 322 is provided at the top end of the rotating flat plate 360.

[0099] As Figure 3 , Figure 5 and Figures 12 to 14 shown, specifically, there are two slide rails 510. Vertical parts 522 are folded downwards on both sides of the main frame 520. Translation guide wheels 523 are respectively provided on the mutually facing sides of the two vertical parts 522. The translation guide wheels 523 are rollingly provided on the slide rails 510. By providing two slide rails 510, the sliding connection area of the main frame 520 is increased, thereby improving the stability of driving the feeding mechanism 300 to horizontally move between the material bucket inventory area and the empty bucket placement area. At the same time, by rollingly providing the translation guide wheels 523 on the slide rails 510, it is beneficial to reduce the friction between the translation guide wheels 523 and the slide rails 510, thereby improving the smoothness of the horizontal movement of the feeding mechanism 300 between the material bucket inventory area and the empty bucket placement area.

[0100] More specifically, the horizontal driving mechanism includes a horizontal rack 541, a translation gear 542, and a translation motor 543. The horizontal rack 541 is horizontally arranged between the two slide rails 510. The translation gear 542 is rotatably arranged at the bottom end of the main vehicle frame 520, and the translation gear 542 meshes with the horizontal rack 541. The translation motor 543 is arranged at the bottom end of the main vehicle frame 520 and drives the translation gear 542 to rotate. Since the horizontal rack 541 is fixed to the foundation or the ground, when the translation motor 543 drives the translation gear 542 to rotate, the translation gear 542 can horizontally move along the horizontal rack 541, thereby stably driving the main vehicle frame 520 to horizontally move between the material bucket storage area and the empty bucket placement area.

[0101] As Figures 15 to 19 shown, in some embodiments, the feeding machine 100 includes a feeding frame 110, and the feeding frame 110 is arranged below the feeding mechanism 300. The opposite upper ends of the feeding frame 110 are provided with a feeding bin 120, and the feeding end of the feeding bin 120 is used for the guide port 3522 to be inserted and communicated. The discharging end of the feeding bin 120 is communicated with a feeding assembly for outputting the materials in the feeding bin 120. The feeding frame 110 is rotatably connected with a tipping hopper 130, and the tipping hopper 130 is driven to rotate by a rotation driving mechanism. The tipping hopper 130 is used for receiving the materials output by the feeding assembly. The opposite lower ends of the feeding frame 110 are provided with a distributing pipe 140. The feeding end of the distributing pipe 140 is used for receiving the materials output by the tipping hopper 130, and the discharging end of the distributing pipe 140 is used for adding the materials into the electrolytic furnace 200. The tipping hopper 130 has a third state of inclining to pour the materials into the distributing pipe 140 and a fourth state of being horizontally arranged and stopping pouring the materials into the distributing pipe 140. By connecting a tipping hopper 130 between the feeding assembly and the distributing pipe 140, after the feeding assembly conveys a fixed amount of materials into the tipping hopper 130 in the fourth state, while stopping the feeding assembly from outputting materials, the tipping hopper 130 is driven to rotate so that the tipping hopper 130 switches from the fourth state to the third state, realizing accurately adding a fixed amount of materials into the electrolytic furnace 200 through the distributing pipe 140 once, improving the weight accuracy of the materials added into the electrolytic furnace 200 each time, and ensuring the quality of electrolysis.

[0102] Specifically, the feeding bin 120 is arranged in a conical shape, and the upper large end of the feeding bin 120 has four symmetrically arranged mounting ears 121, and the mounting ears 121 are mounted on the top of the feeding frame 110.

[0103] Specifically, the inner wall of the feeding end of the feeding bin 120 is provided with an inflatable and expandable sealing part 122.

[0104] AsFigure 16 and Figure 19 As shown, specifically, a rotary mounting base 131 is provided between the tipping hopper 130 and the feeding frame 110. The tipping hopper 130 is rotatably connected to the top of the rotary mounting base 131 through a mounting shaft 132. A weighing sensor is provided at the top of the rotary mounting base 131. The weighing sensor, the rotary driving mechanism and the feeding assembly are all connected to a controller. The tipping hopper 130 in the fourth state presses against the weighing sensor. At this time, when materials are conveyed into the tipping hopper 130, the weighing sensor can detect the weight of the materials in the tipping hopper 130 in real time and transmit the measured weight value to the controller. When the measured weight value is the same as the set weight value, a control signal is transmitted to the rotary driving mechanism and the feeding assembly, so that while stopping the feeding assembly from outputting materials, the tipping hopper 130 is driven to rotate, causing the tipping hopper 130 to switch from the fourth state to the third state, realizing accurately adding a quantitative amount of materials into the electrolytic furnace 200 through the material distribution pipe 140 once, improving the weight accuracy of the materials added into the electrolytic furnace 200 each time, and ensuring the quality of electrolysis.

[0105] In order to further improve the accuracy of the weighing sensor in weighing the materials located in the tipping hopper 130, as Figure 16 shown, more specifically, the mounting shaft 132 is located on one side of the center of the rotary hopper relatively close to the material distribution pipe 140, so that the tipping hopper 130 in the fourth state fully presses against the weighing sensor.

[0106] As Figure 20As shown, specifically, the rotation drive mechanism includes a rotary cylinder 191 disposed on the feeding frame 110. A drive plate 192 is provided at the output end of the rotary cylinder 191. Two feet 1321 are provided at one end of the mounting shaft 132 facing the rotary cylinder 191. The two feet 1321 are spaced apart. The drive plate 192 is embedded between the two feet 1321. When the tipping hopper 130 is in the fourth state, the drive plate 192 is disengaged from the feet 1321. By providing two feet 1321 at intervals on the end face of the mounting shaft 132 facing the rotary cylinder 191 and embedding the drive plate 192 between the two feet 1321, since the height dimension of the drive plate 192 is greater than the distance between the two feet 1321 and the thickness direction of the drive plate 192 is less than the distance between the two feet 1321, after switching the tipping hopper 130 to the fourth state, the drive plate 192 can be rotated to a position where it does not contact the two feet 1321. At this time, the tipping hopper 130 is basically supported by the rotary mounting seat 131, ensuring that the weighing sensor can accurately detect the weight of the tipping hopper 130 and the materials in the tipping hopper 130. When it is necessary to switch the tipping hopper 130 from the fourth state to the third state, the rotary cylinder 191 first drives the drive plate 192 to rotate a free stroke until the drive plate 192 abuts against the two feet 1321, and then rotation can be used to switch the tipping hopper 130 from the fourth state to the third state.

[0107] As Figure 16 shown, in some embodiments, the tipping hopper 130 is disposed obliquely below the discharge end of the feeding bin 120. The feeding machine 100 further includes a first feeding member 150 disposed on the feeding frame 110. The projection of the discharge end of the feeding assembly in the vertical direction falls within the range of the first feeding member 150. The projection of the discharge end of the first feeding member 150 in the vertical direction falls within the range of the tipping hopper 130 in the fourth state. A first linear vibrator 151 is provided between the bottom end of the first feeding member 150 and the feeding frame 110. Since the tipping hopper 130 needs to rotate to automatically switch between the third state and the fourth state, a first feeding member 150 is provided between the discharge end of the feeding assembly and the tipping hopper 130, and there is a clearance space between the first feeding member 150 and the tipping hopper 130 in the vertical direction. This clearance space is used for the part of the tipping hopper 130 that relatively approaches the first feeding member 150 to pass through during flipping and cannot contact the first feeding member 150 to cause interference, realizing the transportation of materials into the tipping hopper 130 without interfering with the rotational movement of the tipping hopper 130. At the same time, by applying a vibration excitation to the materials in the first feeding member 150 through the first linear vibrator 151, the materials are loosened while being transported into the tipping hopper 130 to avoid material caking.

[0108] Specifically, the feeding frame 110 is provided with a mounting table 152, and the first linear vibrator 151 is disposed on the mounting table 152.

[0109] As Figure 16 and Figure 18 shown, specifically, the feeding assembly includes a double-screw conveyor 181. One end of the double-screw conveyor 181 is provided with a driving motor 182, and the other end is provided with a discharge pipe 183. The discharge pipe 183 communicates with the discharge end of the feeding bin 120, and the discharge pipe 183 is used for conveying materials into the tipping hopper 130. The double-screw conveying amount of the double-screw conveyor 181 is more controllable, and it is less likely for the conveyed materials to agglomerate, which is beneficial to improving the later weighing accuracy.

[0110] More specifically, an opening is provided at the upper end of the discharge pipe 183 in the vertical direction, and the opening is connected to the discharge end of the feeding bin 120.

[0111] As Figures 15 to 19 shown, in some embodiments, a first discharge portion 141 and a second discharge portion 142 are communicated with the lower end of the material distribution pipe 140. The first discharge portion 141 and the second discharge portion 142 are oppositely arranged, and the first discharge portion 141 and the second discharge portion 142 respectively feed materials into the corresponding electrolysis furnace 200; a material distribution hopper 160 is rotatably arranged in the feed end of the material distribution pipe 140 through a rotating rod. The material distribution hopper 160 has a fifth state of inclining to pour materials into the first discharge portion 141, a sixth state of horizontally receiving the materials output by the tipping hopper 130, and a seventh state of inclining to pour materials into the second discharge portion 142; one end of the rotating rod extends outside the material distribution pipe 140 and is provided with a third gear 171, and the third gear 171 meshes with a third rack 172, and the third rack 172 is driven by a first electric cylinder 173 to reciprocate linearly. By communicating the first discharge portion 141 and the second discharge portion 142 with the lower end of the material distribution pipe 140, rotatably arranging the material distribution hopper 160 in the feed end of the material distribution pipe 140, and the material distribution hopper 160 alternately conveying a fixed amount of materials to the first discharge portion 141 and the second discharge portion 142, it is realized that only one feeding machine 100 can alternately convey a fixed amount of materials to two electrolysis furnaces 200. At the same time, by providing a third gear 171 meshing with the third rack 172 at one end of the rotating rod, only by controlling the first electric cylinder 173 to drive the third rack 172 to extend and retract, the third gear 171 can be driven to rotate forward or backward, and the material distribution hopper 160 can be automatically driven to switch between the fifth state, the sixth state and the seventh state.

[0112] Specifically, the first discharge portion 141, the second discharge portion 142 and the material distribution pipe 140 are integrally formed and are arranged in an inverted Y shape.

[0113] As Figure 18 and Figure 19 shown, specifically, a sensor mounting seat 111 is provided on one side of the third rack 172 on the feeding frame 110. A first proximity switch 112, a second proximity switch 113 and a third proximity switch 114 are sequentially arranged at intervals along the length direction of the third rack 172 on the sensor mounting seat 111. The first proximity switch 112, the second proximity switch 113, the third proximity switch 114 and the first electric cylinder 173 are all connected to a controller. When the material distribution hopper 160 is in the fifth state, the third rack 172 triggers the first proximity switch 112. When the material distribution hopper 160 is in the sixth state, the third rack 172 triggers the second proximity switch 113. When the material distribution hopper 160 is in the seventh state, the third rack 172 triggers the third proximity switch 114. By respectively providing a proximity switch for the material distribution hopper 160 in different corresponding states, and each proximity switch is connected to the controller, when the third rack 172 moves to trigger one of the proximity switches (the first proximity switch 112, the second proximity switch 113 or the third proximity switch 114), it can be fed back to the controller, and the controller then controls the first electric cylinder 173 to stop, so as to accurately control the telescopic stroke of the first electric cylinder 173, and thus accurately control the material distribution hopper 160 to switch to the fifth state, the sixth state or the seventh state.

[0114] As Figures 15 to 17As shown in the figure, specifically, second conveying members 143 are connected to the discharge ends of the first discharge portion 141 and the second discharge portion 142 in a communicating manner, and the projection of the discharge end of the second conveying member 143 along the vertical direction falls within the range of the corresponding electrolysis furnace 200; a second linear vibrator 144 is provided at the bottom end of the second conveying member 143, and a connecting platform 1443 is provided at one end of the second linear vibrator 144 away from the second conveying member 143. Both the connecting platform 1443 and the feeding frame 110 are adapted to be installed on the ground. Since the temperature of the electrolysis furnace 200 during electrolysis operation is at least 1000 °C, if the discharge ends of the first discharge portion 141 and the second discharge portion 142 are directly above the electrolysis furnace 200, it is easy to cause wear and inconvenient for maintenance; therefore, in this embodiment, the second conveying member 143 is connected in a transitional manner between the discharge ends of the first discharge portion 141 and the second discharge portion 142 and the corresponding electrolysis furnace 200, and the second conveying member 143 is separately provided from the first discharge portion 141 and the second discharge portion 142. When the part of the second conveying member 143 close to the electrolysis furnace 200 is worn and deformed, the worn part can be cut off and continue to be used, which is convenient for short-term maintenance, and only when the total length is not enough, it needs to be replaced. At the same time, the second linear vibrator 144 applies a vibration excitation to the materials located in the second conveying member 143, so that the materials are loosened while being conveyed to the corresponding electrolysis furnace 200 to avoid caking of the materials.

[0115] Specifically, two equal-angle steel bars 145 are provided directly below each of the second linear vibrators 144. The equal-angle steel bars 145 are provided on the connecting platform 1443, and the arrangement direction of the equal-angle steel bars 145 is parallel to the arrangement direction of the second conveying member 143; a support frame 1441 is provided at the bottom end of the second linear vibrator 144, and the bottom end of the support frame 1441 is slidably provided on the equal-angle steel bars 145 through a support V-shaped wheel 1442; by slidably arranging the two second conveying members 143 on the equal-angle steel bars 145 through the support V-shaped wheels 1442, it is possible to adjust the two second conveying members 143 to move towards each other or move away from each other. On the one hand, the relative distance between the discharge end of the second conveying member 143 and the electrolysis furnace 200 can be flexibly adjusted manually, which is convenient for adjusting the optimal feeding port; on the other hand, the two second conveying members 143 can be adjusted to move towards each other, so that the discharge end of the second conveying member 143 is not directly above the electrolysis furnace 200, thus facilitating the work of replacing the furnace platform or anode plate of the electrolysis furnace 200, etc.; on the third hand, when the part of the second conveying member 143 close to the electrolysis furnace 200 is worn and deformed, the worn part can be cut off, and then the two second conveying members 143 are adjusted to move away from each other, so as to ensure that the discharge end of the second conveying member 143 is in the optimal feeding position on the basis of cutting off the worn part of the second conveying member 143 and continuing to use it.

[0116] Specifically, two support V-shaped wheels 1442 are provided between the bottom end of the support frame 1441 and each equal-angle steel 145.

[0117] Such as Figure 1As shown, in some embodiments, the automatic feeding line is applied to a production workshop. The production workshop includes a top layer 600, a middle layer 700, and a bottom layer 800 arranged vertically from top to bottom. On the bottom layer 800, an automatic weighing and scanning area 810, a incoming material inventory area 820, and a feeding machine 100 are sequentially arranged at horizontal intervals. The bottom layer 800 is also provided with a first AGV forklift 830. The first AGV forklift 830 is used to transfer the materials unloaded from a truck to the automatic weighing and scanning area 810. After completing weighing and scanning and entering the scanning data into the ERP system, the first AGV forklift 830 is used to transport the materials that have completed weighing and scanning to the incoming material inventory area 820; A hoist 840 is arranged between the top layer 600 and the bottom layer 800. One end of the hoist 840 is arranged between the automatic weighing and scanning area 810 and the incoming material inventory area 820. The first AGV forklift 830 is also used to transport the materials that have completed weighing and scanning to the hoist 840. The hoist 840 is used to lift the materials from the bottom layer 800 to the top layer 600; On the top layer 600, a stock preparation warehouse 610 and a mixing machine 620 are sequentially arranged at horizontal intervals. The feeding port of the mixing machine 620 is on the floor of the top layer 600. The discharging end of the mixing machine 620 passes through the top layer 600 and extends to the middle layer 700. The stock preparation warehouse 610 is located on the side of the mixing machine 620 relatively close to the hoist 840. The top layer 600 is also provided with a second AGV forklift 630. The second AGV forklift 630 is used to transfer the materials from the hoist 840 to the stock preparation warehouse 610; A grab manipulator 640, an unpacking conveyor line 650, and an unpacking machine 660 are sequentially arranged between the stock preparation warehouse 610 and the mixing machine 620. The grab manipulator 640 is used to grab and transfer the materials on the pallet in the stock preparation warehouse 610 to the unpacking conveyor line 650. The unpacking conveyor line 650 flows the materials into the unpacking machine 660. The unpacking machine 660 unpacks the materials and flows the materials into the mixing machine 620. After the mixing machine 620 completes mixing, it flows a set weight of materials into a bucket 340 at a time and forms a material stack 710; The middle layer 700 is sequentially arranged with a stock preparation inventory area 720, a bucket inventory area, a feeding mechanism 300, and an empty bucket placement area. The stock preparation inventory area 720 is arranged corresponding to the discharging end of the mixing machine 620. The middle layer 700 is provided with a third AGV forklift 730. The third AGV forklift 730 is used to transfer the material stack 710 to the stock preparation inventory area 720; When it is necessary to transport the materials to the feeding machine 100 through the feeding mechanism 300, the third AGV forklift 730 is also used to transfer the material stack 710 from the stock preparation inventory area 720 to the feeding station in the bucket inventory area. After the materials are poured into the feeding machine 100 through the feeding mechanism 300, the entire process from incoming materials to final feeding has a high degree of automation and does not require manual intervention. The material flow is identified and stored through coding, which is traceable, and it is better to master and control the quality of the produced products; At the same time, it avoids workers from intervening in the mixing area with dust and high temperature.

[0118] Specifically, the mixer 620 adopts a conical twin-screw mixer.

[0119] It should be noted that the unpacking conveyor line 650 can be any one of conveyors such as belt conveyors, roller conveyors, and chain plate conveyors. However, considering the load-bearing and better prevention of leakage, a belt conveyor is preferably used.

[0120] As Figure 2 shown, in specific applications, two feeding mechanisms 300 are arranged in parallel, and one third AGV forklift 730 serves the two feeding mechanisms 300 to realize automatic feeding of the two feeders 100.
