The process steps of angle steel galvanizing are pickling-water washing-immersion plating solvent-drying preheating-hang plating-cooling-passivation-cleaning-polishing. The angle iron cooled in the cooling pool is transported to the passivation chamber for passivation treatment. The passivation treatment can form a protective film on the metal surface after cleaning to slow down corrosion. In the prior art, a conveyor belt is provided between the cooling pool and the passivation chamber, and an active roller and a driven roller are rotatably connected to the cooling pool. The active roller is located above the conveyor belt in the vertical direction, and the driven roller is located in the cooling pool. The active roller and the driven roller are connected by a chain. A placement plate for carrying the angle iron is provided on the chain. The rotation of the active roller drives the chain to slide, so that the angle iron in the cooling pool can be driven to move to the conveyor belt through the placement plate, and then the angle iron is transported to the passivation chamber through the conveyor belt.
[0003] However, in the actual production process, it is found that there may be stacking between the angle irons placed on the conveyor belt, which affects the passivation effect of the angle irons and thus affects the quality of the manufactured angle irons. Utility Model Content
[0004] In order to improve the passivation effect of angle irons, the present application provides a transfer device applied to a production line for cooling and passivating angle irons one by one.
[0005] The present application provides a transfer device for the production line of angle iron cooling and passivation, which adopts the following technical solution:

[0007] By adopting the above technical solution, the angle iron cooled in the cooling pool is transported to the storage rack, and then moved to the diversion rack under the action of the transportation component, and moved to the conveying rack after diversion by the diversion component, and finally moved to the passivation chamber under the action of the conveying component. The diversion component can be used to control the number of angle irons placed on the conveying rack at a time, so that the angle irons transported to the passivation chamber are not easy to stack, thereby improving the passivation effect of the angle irons.

Through the setting of the transition block, in the process of placing the angle iron on the transition block, the two angle irons can be separated under the action of vibration, that is, the angle iron can be further diverted, so that the angle iron moved to the conveying rack is not easy to stack, thereby improving the passivation effect of the angle iron.
[0014] Preferably, a plurality of weight-reducing through holes are formed through the diverter block.
[0015] By adopting the above technical solution, the cost for producing the shunt block is reduced by setting the weight-reducing through holes; a plurality of weight-reducing through holes are set, which reduces the production cost and makes the shunt block less likely to deform.
[0016] Preferably, the cross-section of the diverter protrusion is an acute-angled isosceles triangle.
[0017] By adopting the above technical solution, the diverter protrusion can be embedded between the two right-angle sides of the angle iron when the diverter block moves, so that the angle iron can be diverted when being transported by the diverter protrusion, and the number of moved angle irons can be screened, thereby improving the reliability of diverting and moving the angle iron through the diverter block.
[0018] Preferably, a plurality of loading rollers are rotatably connected to the loading block, and the rotation axes of the loading rollers are arranged perpendicular to the length direction of the loading block, and the angle irons on the loading block are fitted with the loading rollers.

[0029] The following is combined with Figure 1-2 The utility model is described in further detail.
[0030] The present application embodiment discloses a transfer device for a production line of angle iron cooling and passivation, which is used to transport the cooled angle iron to a passivation chamber. Figure 1 , including a storage rack 1, a diversion rack 2 and a conveyor rack 3. The angle iron cooled in the cooling pool is conveyed to the storage rack 1. The storage rack 1 is provided with a transport assembly for driving the angle iron to move toward the diversion rack 2. The transport assembly includes three transport belts 11 slidably arranged on the conveyor rack 3. The transport belts 11 slide perpendicularly to the length direction of the angle iron. The storage rack 1 is also rotatably connected with two transport rollers 12. The transport rollers 12 are arranged along the length direction of the angle iron. One of the transport rollers 12 is located at one end of the storage rack 1 close to the diversion rack 2, and the other transport roller 1 2 is located at one end of the storage rack 1 away from the diverter rack 2, three transport synchronous wheels 121 are coaxially fixed on a single transport roller 12, the transport synchronous wheels 121 on the two transport rollers 12 are correspondingly arranged, and the corresponding two transport synchronous wheels 121 are connected through a transport belt 11. A transport motor 13 is also fixedly connected to the storage rack 1, and the output shaft of the transport motor 13 is coaxially fixed with the transport roller 12 close to the diverter rack 2. When the transport motor 13 is started, the angle iron placed on the transport belt 11 can move toward the diverter rack 2 under the action of the belt drive.
[0031] Reference Figure 1The diverter rack 2 includes three inclined loading blocks 21, which are arranged along the length direction of the angle iron. The end of the loading block 21 close to the storage rack 1 is higher in the vertical direction than the end of the loading block 21 close to the conveying rack 3. The end of the loading block 21 close to the storage rack 1 is located at the conveying roller 12 close to the diverter rack 2. The angle iron can move onto the loading block 21 under the action of the belt drive, and then slide along the loading block 21 in the direction away from the storage rack 1 under the action of its own gravity. A loading stopper 211 is provided at the end of the loading block 21 away from the storage rack 1. The loading stopper 211 is used to limit the angle iron from sliding along the loading block 21 under the action of inertia to separate from the loading block 21. There are multiple loading rollers 212 rotatably connected to the loading block 21, and the rotation axis of the loading rollers 212 is arranged perpendicular to the length direction of the loading block 21. The number of the loading rollers 212 depends on the length of the loading block 21, so that the angle iron transported to the loading block 21 is fitted with the side wall of the loading rollers 212. Through the setting of the loading rollers 212, the friction between the angle iron and the loading block 21 is reduced, which facilitates the angle iron to slide along the loading block 21 under the action of its own gravity and reduces the wear of the angle iron during the sliding process.
[0032] Reference Figure 1 , a diversion assembly is provided on the diversion rack 2. The angle iron on the diversion rack 2 is moved to the conveying rack 3 after being diverted by the diversion assembly. The angle iron after being diverted by the diversion assembly is not easy to stack. In the embodiment of the present application, only two angle irons are transported to the passivation chamber at a time, which effectively improves the passivation effect of the angle iron. The diversion assembly includes a diversion block 22 and two control blocks 23. The diversion block 22 is arranged along the sliding direction of the conveying belt 11. With the cooperation of the diversion block 22 and the control block 23, the angle iron on the loading block 21 can be driven to move. In the embodiment of the present application, there are two groups of diversion assemblies. The two groups of diversion assemblies are respectively arranged on both sides of the diversion rack 2. Through the arrangement of the two groups of diversion assemblies, the reliability of driving the angle iron to move by the diversion assembly is improved.
[0033] Reference Figure 1 , two diverter rollers 24 are rotatably connected to the diverter frame 2, one of the control blocks 23 is rotatably connected to one of the diverter rollers 24, and the other control block 23 is rotatably connected to the other diverter roller 24. Both diverter rollers 24 are coaxially provided with diverter synchronous wheels 242, and the diverter frame 2 is slidably connected to the diverter synchronous belt 241. The two diverter synchronous wheels 242 are connected through the diverter synchronous belt 241. When one of the diverter rollers 24 rotates, the other diverter roller 24 can rotate synchronously under the action of the diverter synchronous belt 241, thereby improving the reliability of driving the diverter block 22 to move by the rotation of the control block 23. A diverter motor 25 is fixedly connected to the diverter frame 2, and the output shaft of the diverter motor 25 is coaxially fixed to one of the diverter rollers 24. The diverter motor 25 is started to drive the diverter roller 24 to rotate.
[0034] Reference Figure 1A transition block 26 is provided at one end of the loading block 21 close to the conveying rack 3, and the transition block 26 extends toward the conveying rack 3. A transition stopper 261 is provided at one end of the transition block 26 away from the storage rack 1. The transition stopper 261 is used to limit the angle iron from separating from the transition block 26. The angle iron on the loading block 21 can be placed on the transition block 26 first under the action of the diverter block 22, and the angle iron previously placed on the transition block 26 can be moved to the conveying rack 3 under the action of the diverter block 22. Through the setting of the transition block 26, during the process of placing the angle iron on the transition block 26, the two angle irons can be separated under the action of vibration, that is, the angle iron can be further diverted, so that the angle iron moved to the conveying rack 3 is not easy to stack, thereby improving the passivation effect of the angle iron.
[0035] Reference Figure 1 Two groups of diversion protrusions 221 are provided on the side of the diversion block 22 away from the control block 23. The two groups of diversion protrusions 221 are symmetrically arranged on both sides of the axis of the diversion block 22. There are three single-group diversion protrusions 221. The cross-section of the diversion protrusion 221 is an acute-angled isosceles triangle. When the diversion block 22 moves, the diversion protrusion 221 can be embedded between the two right-angled sides of the angle iron, which can not only divert the angle iron when transporting the angle iron and screen the number of the moved angle iron, but also make it difficult for the angle iron on the diversion block 22 to detach from the diversion block 22 during the movement of the diversion block 22, thereby improving the reliability of diverting and moving the angle iron through the diversion block 22.
[0036] Reference Figure 1 , a plurality of weight-reducing through holes 222 are provided on the shunt block 22. In the embodiment of the present application, there are two weight-reducing through holes 222. The provision of the weight-reducing through holes 222 reduces the cost of producing the shunt block 22. A sensor 27 is fixedly connected to the loading block 21. The sensor 27 is used to identify the angle iron moved to the loading block 21. In the embodiment of the present application, the sensor 27 is an infrared sensor 27. The position of the sensor 27 is adjusted. When the two angle irons move to one end of the loading block 21 close to the transition block 26, the red line emitted by the sensor 27 can be blocked. Then the shunt motor 25 is started. By moving the shunt block 22 to transport the angle iron, it is not easy for the shunt block 22 to be empty, thus saving energy.
[0037] Reference Figure 2 and Figure 3The conveying frame 3 is provided with a conveying assembly for driving the angle iron to be conveyed toward the passivation chamber. The conveying assembly includes a plurality of conveying rollers 31 rotatably connected to the conveying frame 3. The rotation axis of the conveying roller 31 is arranged along the length direction of the angle iron. The number of conveying rollers 31 depends on the length direction of the conveying frame 3. A conveying synchronous sprocket 311 is coaxially arranged on the conveying roller 31. A synchronous chain 32 is arranged on the conveying frame 3. The synchronous sprockets 311 on the plurality of conveying rollers 31 are all meshed with the synchronous chain 32. A conveying motor 33 is also fixedly connected to the conveying frame 3. The output shaft of the conveying motor 33 is coaxially fixed with one of the conveying rollers 31. After the conveying motor 33 is started, the conveying roller 31 can rotate synchronously under the action of the chain drive. The end of the conveying frame 3 away from the diverter frame 2 is overlapped with the passivation chamber. The diverter block 22 can move the angle iron on the transition block 26 to the conveying roller, and then the angle iron slides toward the passivation chamber under the action of the transmission roller.
[0038] The implementation principle of a transfer device used in a production line for cooling and passivating angle irons one by one in an embodiment of the present application is as follows: the angle irons cooled in a cooling pool are conveyed to a storage rack 1, and then moved to a loading block 21 under the action of a transport assembly; the angle irons on the loading block 21 move to one end of the loading block 21 close to the conveying rack 3 under the action of their own gravity; the two angle irons on the loading block 21 are moved to a transition block 26 through the movement of a diverter block 22; at the same time, the two angle irons originally on the transition block 26 are moved to the conveying rack 3; finally, the angle irons are moved to a passivation chamber under the action of a conveying assembly.
