Description

Technical Field

[0001] This utility model belongs to the technical field of galvanized steel sheet production equipment, and in particular relates to a spraying device for the wet finishing machine roller system in galvanized steel sheet production. Background Technology

[0002] The wet finishing process in a galvanized steel sheet production line is a crucial step in eliminating the yield plateau and improving the sheet shape. When the galvanized steel sheet passes through the wet finishing machine, zinc particles and powder from the galvanized sheet gradually adhere to the work rolls that contact the sheet and the support rolls that support them. As the throughput of the finishing machine increases, these zinc particles and powder gradually accumulate to form zinc dross, altering the surface roughness of the work rolls. This roughness directly affects the surface quality of the steel sheet. Furthermore, the zinc dross adhering to the work rolls causes poor contact with the steel sheet, preventing the finishing process from achieving its intended effect. Therefore, high pressure is typically applied to the upper and lower work rolls and the upper and lower support rolls of the finishing machine. Water jet blowing devices, while commonly used, can move along the roller axis. However, they cannot adjust the distance between the nozzle and the roller surface or the blowing angle. Prolonged blowing at a single angle, under the long-term impact and reaction force of the high-pressure water flow, will cause the fixed support of the blowing device to bend and deform, resulting in a change in the blowing position. This prevents accurate targeting of areas requiring focused blowing and also fails to remove slag from other areas on the roller. Consequently, zinc slag on the working and support roller surfaces is difficult to remove completely, significantly impacting the quality of the finished sheet. Furthermore, once bent, the blowing device becomes unusable, has a short lifespan, and requires periodic replacement, affecting both overall production progress and increased production costs.

[0022] like Figure 1-4As shown, the present invention relates to a galvanizing line wet finishing machine roller system blowing device, comprising a blowing pipe 1, a support frame 2, and a support beam 3. The support beam 3 is located between two columns 43 at the discharge end of the wet finishing machine 4, and is parallel to and corresponds to the working roller 41 and support roller 42 of the wet finishing machine 4. The blowing pipe 1 is arranged in pairs at the upper and lower ends of the support frame 2, and is mounted on the support beam 3 via the support frame 2. The support frame 2 and the support beam 3 are slidably connected, and a corresponding translation device 5 is provided between them. The support frame 2 can slide left and right along the support beam 3 under the action of the translation device 5, thereby driving the blowing pipe 1 to move left and right relative to its working roller 41 and support roller 42 at the discharge end of the wet finishing machine 4. The outlet end of the blowing pipe 1 corresponds to the working roller 41 and support roller 42 of the wet finishing machine 4, and its inlet end is externally connected to a corresponding high-pressure water pipe. The high-pressure water pipe provides high-pressure water to the blowing pipe 1. The zinc dross adhering to the surfaces of the working rollers 41 and support rollers 42 of the wet finishing machine 4 is blown away from the outlet end of the blowing pipe 1. A corresponding adjusting device 6 is provided between the blowing pipe 1 and the support frame 2. The adjusting device 6 can adjust the distance and angle between the outlet end of the blowing pipe 1 and the wet finishing machine 4, thereby realizing multi-force and multi-directional blowing of the working rollers 41 and support rollers 42 of the wet finishing machine 4 by the blowing pipe 1. A control console 7 associated with the above components is provided on the outside of the wet finishing machine 4. The operator presets and controls the operation of the blowing device through the control console 7. In use, the roller system blowing device of the wet finishing machine of the galvanizing line of this utility model is set in pairs on the upper and lower sides of the discharge end of the wet finishing machine 4. The two blow the working rollers 41 and support rollers 42 on the upper and lower sides of the steel plate 44 respectively. In this embodiment, the blowing device above the steel plate 44 is taken as an example.

[0023] The jetting pipe 1 is mirror-image positioned at the upper and lower ends of the support frame 2, corresponding to the support roller 42 and working roller 41 of the wet finishing machine 4, respectively. In this embodiment, the jetting pipe 1 at the upper end of the support frame 2 is used as an example. It is installed at the top of the support frame 2 via a corresponding adjusting device 6, corresponding to the support roller 42. It includes a high-pressure nozzle 11, an outlet pipe 12, an inlet pipe 13, and a telescopic pipe 14. The high-pressure nozzle 11 is located at the outlet end of the outlet pipe 12, corresponding to the wet finishing machine 4. The inlet end of the outlet pipe 12 is connected to the outlet end of the inlet pipe 13. The inlet end of the inlet pipe 13 is externally connected to a corresponding high-pressure water circuit. A control valve 16 associated with the control console 7 is installed on the inlet pipe 13. The control console 7 controls the flow of high-pressure water in the inlet pipe 13 via the control valve 16. Under the control of the control valve 16, high-pressure water is supplied to the outlet pipe 12. The high-pressure water in the outlet pipe 12 is sprayed out to the wet finishing machine 4 through the high-pressure nozzle 11, thereby washing away the zinc slag on the corresponding roller surface. The telescopic pipe 14 is located between the inlet pipe 13 and the outlet pipe 12. It is a telescopic hose. When the adjustment device adjusts the distance and angle between the high-pressure nozzle 11 and the wet finishing machine 4, the telescopicity of the telescopic pipe 14 provides an auxiliary function. In this embodiment, the two spray pipes 1 corresponding to the upper and lower ends of the support frame 2 and the adjustment device 6 corresponding to the spray pipes 1 are mirror-corresponding to each other along the center line. The two spray pipes 1 spray the corresponding working roller 41 and support roller 42 on the wet finishing machine 4 respectively. The inlet ends of the inlet pipes 13 of the two spray pipes 1 are connected in parallel to each other, and the two are connected in parallel to the same high-pressure water circuit.

The outlet end of the water inlet pipe 13 passes through the fourth support 26 and connects to the telescopic pipe 14. The water inlet pipe 13 and the fourth support 26 are fixedly connected. Thus, with the assistance of the guide groove 27 and the cooperation of the telescopic pipe 14, the high-pressure nozzle 11 can change the distance between itself and the corresponding support roller 42 through the outlet pipe 12 under the action of the horizontal hydraulic cylinder 61 as its horizontal telescopic rod 64 extends and retracts. The vertical hydraulic cylinder 62 is provided on the side corresponding to the horizontal hydraulic cylinder 61 in the vertical direction. In this embodiment, it is provided below the horizontal hydraulic cylinder 61. Its bottom end is rotatably connected to the support frame 2 through the corresponding vertical base 65. Its top end is provided with a corresponding The vertical telescopic rod 66 has its top end rotatably connected to the side wall of the horizontal telescopic rod 64. When the vertical telescopic rod 66 extends or retracts under the action of the vertical hydraulic cylinder 62, the top end of the horizontal telescopic rod 64 can slide in a fan shape with the horizontal base 63 as the center, and the blowing direction of the high-pressure nozzle 11 is adjusted accordingly. In use, the control console 7 controls the distance between the high-pressure nozzle 11 and the wet polishing machine 4 through the horizontal hydraulic cylinder 61, and controls the blowing direction of the high-pressure nozzle 11 through the vertical hydraulic cylinder 62. In this way, through the cooperation of the horizontal hydraulic cylinder 61 and the vertical hydraulic cylinder 62, the blowing angle and direction of the high-pressure nozzle 11 on the support roller 42 in the vertical direction can be flexibly adjusted.
