[0018] In the first embodiment of the present application, as Figure 1 and Figure 2 shown, this hot-dip galvanizing production line with both hanging and blowing functions (hereinafter simply referred to as "this application") includes a loading machine 1, a loading machine track 2, a closed pickling tank 3, an unloading pit 4, a fixture 5, a galvanizing pot 8, a water tank inspection conveyor 9, a blowing and passivating roller path 10, a bagging conveyor 11, a bagging machine 12, a cooling tank 13, a hanging passivating tank 14, a galvanizing machine 16, an RGV vehicle 17, a circular track 18, a blowing feeding assembly 19, a transfer chain machine 19-1, an automatic material distributor 19-2, a material turning machine 19-3, and a feeding conveyor 19-4. The loading machine 1 hangs the fixture 5 and runs back and forth on the loading machine track 2. One end of the loading machine track 2 enters the closed pickling tank 3, and an unloading pit 4 is arranged at the outlet of the closed pickling tank 3. A circular track 18 connected end to end is arranged above the unloading pit 4. Below the circular track 18, a translatable blowing transfer 6, a galvanizing pot 8, a cooling tank 13, and a hanging passivating tank 14 are arranged in sequence; the blowing transfer 6 is connected to a blowing line 7, and the blowing line 7 is connected to the automatic material distributor 19-2 through the transfer chain machine 19-1 of the blowing feeding assembly 19. The automatic material distributor 19-2 is connected to the galvanizing pot 8 through the feeding conveyor 19-4. The feeding conveyor 19-4 is equipped with a material turning machine 19-3. The upper part of the galvanizing pot 8 is equipped with a galvanizing machine 16, and the galvanizing machine 16 is equipped with a galvanizing machine translation and maintenance mechanism 15. The cooling tank 13 is connected to the blowing and passivating roller path 10 through the water tank inspection conveyor 9. The blowing and passivating roller path 10 is connected to the bagging conveyor 11 and the bagging machine 12. Three groups of RGV vehicles 17 run unidirectionally on the circular track 18, and the three groups of RGV vehicles 17 are connected to the fixture 5 through hooks.

[0019] The structure of the second embodiment is basically the same as that of the first embodiment, except that the closed pickling tank 3 is a closed space, and inside the closed pickling tank 3, there are pickling tanks, weight reduction tanks, rinsing tanks, and plating assistant tanks. There are three groups of RGV vehicles 17 installed inside the closed pickling tank 3 to complete the process actions of workpiece grasping, lifting, workpiece water control, transportation, lowering, discharging, and angle adjustment.

[0020] To further optimize the working efficiency of this application and dry the workpieces as soon as possible, the discharging pit 4 is equipped with a drying device.

[0021] For ease of operation, the plating transfer 6 is equipped with a ground rail vehicle and a manual hoist. To make it easier for the workpieces to be extracted from the cooling tank 13 by the water tank inspection conveyor 9, the cooling tank 13 is provided with a lifting device that cooperates with the water tank inspection conveyor 9.

[0022] The production method of the hot-dip galvanizing production line with dual lifting and blowing plating for the hanging plating line includes the following steps:

[0023] In the blowing plating mode, the workpieces sequentially pass through the loading machine 1, the loading machine track 2, the closed pickling tank 3, the discharging pit 4, the blowing plating transfer 6, the blowing plating line 7, the galvanizing machine translation and maintenance mechanism 15, the galvanizing pot 8, the cooling tank 13, the water tank inspection conveyor 9, the blowing plating passivation roller path 10, the bagging conveyor 11, and the bagging machine 12 to finally complete the blowing plating process;

[0024] In the hanging plating mode, the workpieces sequentially pass through the loading machine 1, the loading machine track 2, the closed pickling tank 3, the discharging pit 4, the galvanizing pot 8, the cooling tank 13, and the hanging plating passivation tank 14, and are finally transported out of the production line by the overhead crane on the ground to finally complete the hanging plating process.

[0025] When in use, install a hot-dip galvanizing production line with dual lifting and blowing plating, and the equipment can be put into use.

[0026] When this application is in use, the specific operation is as follows:

[0027] When in use, the workpieces are grasped by the fixture 5, and then fed through the side entrance ground rail vehicle along the loading machine track 2 by the loading machine 1, and sent into the closed pickling tank 3 to ensure the sealing of the closed room. The blowing plating and hanging plating share the same loading. Then, the RGV vehicle 17 in the closed pickling tank 3 hoists the fixture 5 and passes through the pickling tank, weight reduction tank, rinsing tank, and plating assistant tank one by one. The three groups of RGV vehicles 17 are used to complete the process actions of workpiece grasping, lifting, workpiece water control, transportation, lowering, discharging, and angle adjustment; the materials are then sent into the discharging pit 4, and after being dried by the drying device in the discharging pit 4, they can enter the hanging plating line or the blowing plating line respectively.

[0028] When entering the blowing plating line, the RGV vehicle 17 on the circular track 18 grabs the fixture 5, and the fixture 5 places the workpiece on the blowing plating transporter 6. The blowing plating transporter 6 then conveys it to the blowing plating line 7. After being processed by the blowing plating line 7, it is then conveyed to the galvanizing pot 8 for galvanizing by the transfer chain machine 19-1, automatic material distributor 19-2, material turning machine 19-3, and feeding conveyor 19-4 of the blowing plating loading assembly 19. At this time, the galvanizing machine 16 is moved out of the galvanizing pot 8 through the galvanizing machine translation maintenance mechanism 15. After the workpiece for blowing plating is galvanized in the galvanizing pot 8, it is output to the cooling pool 13 through the output roller table, cooled by the cooling pool 13, and then enters the warehouse after being processed by the water tank inspection conveyor 9, blowing plating passivation roller table 10, and packing conveyor 11 in sequence;

[0029] When entering the hanging plating line, the RGV vehicle 17 on the circular track 18 directly conveys the materials in the discharging pit 4 to the galvanizing pot 8 through the fixture 5, and the galvanizing is carried out by the galvanizing machine 16 that has been reset. After the galvanizing is completed, it is cooled by the cooling pool 13, then enters the hanging plating passivation pool 14 for treatment, and finally is lifted to the transport vehicle by the RGV vehicle 17 through the fixture 5 and sent to the warehouse.

[0030] In summary, for a hanging and blowing dual-purpose hot-dip galvanizing production line according to an embodiment of the present application, by adding a blowing plating line 7, one production line can be shared for blowing plating and hanging plating, greatly improving the utilization rate of the galvanizing pot, diversifying the products, and making up for the deficiencies of blowing plating and hanging plating.
