[0044] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] like Figures 1 to 12 As shown, a powder loading and recycling device for metal plating includes:

[0046] The tank assembly is configured to move multiple unit tanks to a tank assembly position to combine them into a tank body. The tank assembly includes two tank trolleys 51, which are movably connected to the tank trolley track 511 by rollers.

[0047] The powder filling assembly 4 is configured to fill the tank with powder and recover the powder after the tank is opened. The powder filling assembly 4 includes a batching platform 41 and a feeding hopper 43. The tank closing track is located below the batching platform 41. The lower end of the feeding hopper 43 is provided with a discharge pipe 432, which corresponds to the position of the powder inlet of the tank.

[0048] The tank assembly includes two tank trolleys 51, which are movably connected to a tank track 511 via rollers. The tank track 511 is arranged parallel to the length direction of the reinforcing bars.

[0049] One end of the tank-combining platform 512 of the tank-combining vehicle 51 is fixed with a positioning barrel 513 that matches the unit tank, and the other end is provided with an arc-shaped clamping plate 514 for clamping the unit tank. There are two arc-shaped clamping plates 514, and the two arc-shaped clamping plates 514 form a clamping position for clamping the unit tank. The lower end of the arc-shaped clamping plate 514 has a guide groove. The tank-combining vehicle 51 is fixed with a guide bar 515 that is set along the moving direction of the arc-shaped clamping plate 514. The guide bar 515 is located inside the guide groove, and the inner diameter of the arc-shaped clamping plate matches the outer diameter of the unit tank. The setting of the guide groove and the guide bar 515 makes the movement process of the arc-shaped clamping plate 514 more stable.

[0050] Each arc-shaped clamping plate 514 has a corresponding tank-closing upright plate 517 on its end face away from the clamping position. The tank-closing upright plate 517 is equipped with a cylinder that drives the arc-shaped clamping plate 514. The housing of the cylinder is fixedly connected to the tank-closing upright plate 517, and the output shaft of the cylinder is connected to the arc-shaped clamping plate 514.

[0051] The tanker 51 is equipped with two guide wheels 516, which are located on both sides of the unit tank axis. The sidewalls of the guide wheels 516 are in contact with the outer sidewalls of the unit tank.

[0052] The working process of tanker truck 51 is as follows:

[0053] Two unit tanks are installed on two combined tank cars 51 respectively. The arc-shaped clamping plate 514 clamps one end of the opening of the unit tank, and the other end of the unit tank is located inside the positioning barrel 513. The two combined tank cars 51 move towards each other, and the steel bars are inserted into the inside of the unit tank. The unit tanks are connected by a bayonet to form a tank body.

[0054] When adding powder, the tanker truck 51 moves below the batching platform 41 to add powder raw materials into the tank. Then the tanker truck 51 moves to the tanking position, and the tank is moved to the buffer component by the hoisting component.

[0055] When disassembling the tank, the positioning bucket 513 of the tank merging car 51 is aligned with the tank, the two tank merging cars 51 move towards each other, the arc-shaped clamping plate 514 clamps one end of the opening of the unit tank, and then the tank merging car 51 moves to the top of the vibration table 455. After opening the tank's latch, the two tank merging cars 51 move in opposite directions, and the steel bars come out from the two unit tanks and fall on the vibration table 455. After the vibration is completed, the tank merging car 51 returns to the tank merging position.

[0056] Powder filling component 4 includes:

[0057] The batching platform 41 has a tank closing track located below it, and the batching platform 41 has a strip-shaped discharge hole 411 set along the length of the tank body.

[0058] The feeding hopper 43 has an inverted conical structure.

The feeding hopper 43 is movably connected to the feeding track 431 by rollers. The feeding track 431 is arranged parallel to the strip-shaped discharge hole 411.

[0059] The batching tower 42 includes a vacuum feeder 423, a batching tank 421, and a mixing tank 422. The discharge end of the vacuum feeder 423 is connected to multiple raw material tanks. The discharge end of each raw material tank is connected to the mixing tank 422 through an auger. The discharge port of the mixing tank 422 is connected to the feeding hopper 43 through a vacuum feeder. Multiple powder raw materials are mixed by the stirring paddle inside the mixing tank 422.

[0060] The powder filling assembly 4 is equipped with a dust cover on the outside.

[0061] The working process of powder filling component 4 is as follows:

[0062] The powder filling process is as follows: the raw materials are mixed in the mixing tank 422 according to the proportion. The mixed powder is fed into the feeding hopper 43 through the vacuum discharge machine. The feeding hopper 43 moves along the feeding track 431. After the discharge pipe 432 is aligned with the powder inlet of the tank, the valve on the discharge pipe 432 is opened and the powder enters the inside of the tank.

[0063] Powder filling component 4 also includes:

[0064] The vibration frame 45 includes a vibration base 456 and a vibration table 455. A spring 458 is provided between the vibration base 456 and the vibration table 455. A vibration motor 457 is provided on the vibration table 455. A support plate 451 is fixedly provided at the upper end of the vibration table 455. Steel bars 452 are provided at both ends of the support plate 451. Powder guide plates 453 are fixedly provided on both sides of the support plate 451. The end of the powder guide plate 453 away from the support plate 451 is inclined downward. A first baffle 454 is provided on the edge of the powder guide plate 453 away from the support plate 451. The first baffle 454 prevents the steel bars from slipping off the support plate 451. The height of the tank truck 51 is higher than the height of the vibrating frame 45. The vibrating motor 457 adopts, but is not limited to, the existing eccentric wheel motor. The output shaft of the motor is equipped with an eccentric wheel. The spring 458 plays a reset role to keep the vibrating table 455 in a vibrating state. In some embodiments, the lower end of the vibrating table 455 is provided with a guide post. The guide post is located inside the guide hole of the vibrating base 456, and the spring 458 is located outside the guide post, so that the vibrating table 455 can only vibrate in the up and down direction.

[0065] A powder tilting plate 44 is located below a powder guide plate 453. Second baffles 441 are fixed on both sides of the powder guide plate 453. Multiple powder tilting plates 44 are arranged along the length of the tank track 511. A vibration frame 45 is provided between adjacent powder tilting plates 44. The powder guide plate 453 is triangular and located above the powder tilting plate 44. The vertical projections of the powder guide plate 453 and the powder tilting plate 44 overlap along the side of the powder tilting plate 44.

[0066] The powder conveying assembly includes a first auger 46, a vertical elevator 47, and a second auger 48 connected in sequence. The side wall of the first auger 46 has an opening corresponding to the lower end of the powder inclined plate 44, and the discharge end of the second auger 48 corresponds to the upper end of the discharge hopper. The augers and the vertical elevator 47 are existing technologies and will not be described in detail here.

[0067] A rebar transfer assembly 49 is movably connected to a rebar transfer track 491 via rollers. The rebar transfer track 491 is arranged parallel to the length direction of the rebar. The rebar transfer assembly 49 includes a moving platform 494, with a U-shaped hook 492 at its lower end. The crossbar of the U-shaped hook 492 is horizontally arranged. One crossbar of the U-shaped hook 492 is connected to the moving platform 494 via a lifting rod, which is movably connected to the moving platform 494 along the height direction. A third baffle 493 is provided on the other crossbar of the U-shaped hook 492 to prevent the rebar from detaching from the lower crossbar of the U-shaped hook 492. The U-shaped hook 492 can be movably connected to the moving platform 494 along the height direction using a winch.

[0068] The working process of powder filling component 4 is as follows:

[0069] The can unpacking process is as follows: After the can's latch is opened, the two combined tank cars 51 move in opposite directions. Unused powder raw materials flow through the powder guide plate 453 and the inclined flow to the inside of the first auger 46. The reinforcing bars are placed on the support plate 451 of the vibrating frame 45. The vibrating motor 457 is started to drive the reinforcing bars to vibrate, which causes the reinforcing bars to vibrate and separate the powder raw materials from the reinforcing bars. Used powder raw materials flow through the powder guide plate 453 and the powder inclined plate 44 to the inside of the first auger 46. The powder raw materials enter the feeding hopper 43 for reuse through the first auger 46, the vertical elevator 47, and the second auger 48. The lower horizontal bar of the U-shaped hook 492 is located below the reinforcing bars in the initial position. After the powder separation is completed, the U-shaped hook 492 moves upward, causing the reinforcing bars to detach from the support. Then the reinforcing bar transfer assembly 49 moves along the reinforcing bar transfer track 491 to the next process.

[0070] Work process:

[0071] A method for filling and recycling powder includes the following steps:

[0072] The tank assembly moves multiple unit tanks to the tank assembly position to combine them into a tank body, with the reinforcing steel bars located inside the tank body. The specific process is as follows:

[0073] Two unit tanks are installed on two combined tank cars 51 respectively. The arc-shaped clamping plate 514 clamps one end of the opening of the unit tank, and the other end of the unit tank is located inside the positioning barrel 513. The two combined tank cars 51 move towards each other, and the steel bars are inserted into the inside of the unit tank. The unit tanks are connected by a bayonet to form a tank body.

[0074] The powder filling component 4 adds powder raw materials into the tank, and the specific process is as follows:

[0075] The raw materials are mixed in the mixing tank 422 according to the proportion. The mixed powder is fed into the feeding hopper 43 through the vacuum discharge machine. The feeding hopper 43 moves along the feeding track 431. After the discharge pipe 432 is aligned with the powder inlet of the tank, the valve on the discharge pipe 432 is opened and the powder enters the inside of the tank.

[0076] When adding powder, the tanker truck 51 moves below the batching platform 41 to add powder raw materials into the tank. Then the tanker truck 51 moves to the tanking position, and the tank is moved to the buffer component by the hoisting component.

[0077] The hoisting assembly moves the tank to the buffer assembly, and the tank-moving assembly moves the tank from the buffer assembly into the furnace. The specific process is as follows:

[0078] The two curved clamps of the can-lifting jaws move in opposite directions. After the can-lifting jaws move downwards and the curved clamps align with the can body, the two curved clamps move towards each other to clamp the can body. The can-lifting car 51 moves in opposite directions, and then the can-lifting jaws move upwards and to the buffer assembly, placing the can body in the buffer channel.

[0079] The can-transferring assembly moves along the can-transferring track until it is aligned with the buffer channel. The first and second rotating shafts rotate in the same direction, moving the can from the buffer channel into the can-transferring channel. The can-transferring assembly moves along the can-transferring track to the furnace opening. The screw jack moves and lifts the can-transferring lifting plate, aligning the can-transferring channel with the furnace opening. The second rotating shaft rotates and moves the can into the furnace.

[0080] The can-moving assembly moves the can inside the furnace onto the buffer assembly.

[0081] Disassemble the can at point 4 of the powder filling assembly and collect any unused powder.

[0082] During the furnace discharge process, the lifting jaws lift the tank to the corresponding position of the tank assembly car 51, and the tank assembly car 51 clamps the tank and moves it to the tank disassembly position.

[0083] The positioning bucket 513 of the two tank merging cars 51 aligns with the tank body. The two tank merging cars 51 move towards each other, and the arc-shaped clamping plate 514 clamps one end of the opening of the unit tank. Then, the tank merging cars 51 move above the vibration table 455. After opening the tank body's latch, the two tank merging cars 51 move in opposite directions. The reinforcing bars come out from the two unit tanks and fall onto the vibration table 455. After vibration, the tank merging cars 51 return to the merging position. After the tank body's latch opens, the two tank merging cars 51 move in opposite directions. Unused powder raw materials flow through the powder guide plate 453 and the inclined flow to the inside of the first auger 46. The reinforcing bars are placed on the vibration frame 45. On the support plate 451, the vibration motor 457 starts and drives the steel bar to vibrate, so that the vibration of the steel bar separates the powder raw material from the steel bar. The used powder raw material flows through the powder guide plate 453 and the inclined flow to the inside of the first auger 46. The powder raw material enters the feeding hopper 43 for reuse through the first auger 46, the vertical elevator 47, and the second auger 48. The lower end of the crossbar of the U-shaped hook 492 is located below the steel bar in the initial position. After the powder separation is completed, the U-shaped hook 492 moves upward, driving the steel bar to detach from the support. Then the steel bar transfer assembly 49 moves along the steel bar transfer track 491 to the next process.

[0084] The powder filling component 4 not only serves the function of filling powder raw materials, but also plays a role in recovering powder raw materials during the can opening process, thereby improving the utilization rate of plant space and powder materials.

[0085] Compared to traditional manual filling of powder raw materials, the method of filling the tank with powder raw materials through the feeding hopper on the top of the tank and the movement of the tank merging vehicle to complete the tank merging, powder filling and tank dismantling operations in a coordinated manner improves work efficiency.
