[0022] See Figures 1-4 This utility model provides the following two technical solutions:

[0023] First embodiment: An array-type spray pretreatment device in a strip steel pickling system, including a mounting frame 1, the mounting frame 1 being connected to a treatment component for spray pretreatment in the strip steel pickling system, the treatment component including:

[0024] Adjusting component 2, set on mounting frame 1 for adjusting the position of the spray end, includes an array of screws 21 threaded to both sides of mounting frame 1, a bidirectional screw 23 rotatably connected to the middle of mounting frame 1, a first motor 24 fixedly connected to the front of mounting frame 1 for driving the bidirectional screw 23 to rotate, a spray component 25 connected to the bidirectional screw 23, and a set of sliding rods 22 fixedly connected to both ends of the inner side of mounting frame 1 for providing support for the spray component 25. The spray component 25 includes two sets of movable frames 251 threaded to both sides of the bidirectional screw 23 and slidably connected to the sliding rods 22, an array of sleeves 252 rotatably connected to the lower side of movable frames 251, a rotating block 253 fixedly connected to the right side of sleeves 252, a nozzle 254 vertically fixedly connected to the rotating block 253, and a bellows 255 fixedly connected to the top of nozzle 254.

[0025] The driving component 3 is set on the mounting frame 1 for driving the sleeve 252. The driving component 3 includes an array of cross shafts 31 rotatably connected in the mounting frame 1. The cross shafts 31 are slidably connected to the sleeve 252. A second motor 32 for driving the cross shafts 31 to rotate is fixedly connected to the left side of the mounting frame 1. The output end of the first motor 24 is coaxially fixedly connected to the bidirectional screw 23. A set of sliding grooves slidably connected to the slide rod 22 are provided on both sides of the moving frame 251. A cross groove slidably connected to the cross shaft 31 is provided in the middle of the sleeve 252.

[0026] The bellows 255 is connected to the external pickling solution supply end. The slide bar 22 and the bidirectional screw 23 are both set on the mounting frame 1 along the Y-axis. The driving component 3 also includes a drive shaft 33 rotatably connected to the inside of the rear side of the mounting frame 1 and driven by the second motor 32. The drive shaft 33 is connected to a set of bevel gear assemblies 34 corresponding to the cross shaft 31. A positioning plate 35 is coaxially fixedly connected to the right side of the cross shaft 31. An electric push rod 36 is fixedly connected to the front end of the positioning plate 35 on the inner side of the mounting frame 1. A positioning pin 37 is fixedly connected to the end of the electric push rod 36 near the positioning plate 35 on the extended side of the electric push rod 36. The output end of the second motor 32 is coaxially fixedly connected to the drive shaft 33. The output end of the drive shaft 33 is coaxially fixedly connected to the driving bevel gear in the bevel gear assembly 34. The driven bevel gear in the bevel gear assembly 34 is coaxially fixedly connected to the cross shaft 31. A first movable groove is provided on the side of the mounting frame 1 near the bevel gear assembly 34.

[0027] Both the first motor 24 and the second motor 32 are servo motors. The mounting frame 1, slide bar 22, bidirectional screw 23, and the first motor 24 cooperate with each other to adjust the horizontal spacing of the two sets of moving frames 251, several sleeves 252, rotating blocks 253, and nozzles 254. The array of bevel gear assemblies 34, cross shaft 31 cooperate with the second motor 32 and drive shaft 33 to synchronously adjust the angles of several sleeves 252, rotating blocks 253, and nozzles 254 so that the nozzles 254 face the end of the strip to be pickled.

[0028] The main difference between the second implementation method and the first implementation method is that:

[0029] The positioning plate 35 has several positioning grooves on its edge corresponding to the positioning pin 37. The positioning pin 37 matches the positioning groove. The inner side of the mounting frame 1, near the positioning plate 35 and the positioning pin 37, has a second movable groove. After the nozzle 254 is rotated to a suitable angle, the electric push rod 36 drives the positioning pin 37 to be inserted into the positioning groove on the side of the positioning plate 35, thereby locking the angle of the nozzle 254.

[0030] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0031] In use, the user installs the mounting frame 1 in the corresponding position within the steel strip pickling system using screws 21, electrically connecting the first motor 24, the second motor 32, and the electric push rod 36 to an external controller. Several corrugated pipes 255 are installed at their upper ends on the pickling solution supply end. The installation of the corrugated pipes 255 is existing technology, so its specific steps will not be detailed here. The first motor 24 is started, and it adjusts the distance between the two sets of moving frames 251 via a bidirectional screw 23. The moving frames 251 slide along the two sets of sliding rods 22, driving several sleeves 252, rotating blocks 253, and nozzles 254 to move synchronously. During this process, the sleeves 252 slide along the cross shaft 31. When the two sets of moving frames 25... 1. After reaching a suitable distance, the first motor 24 is turned off. The second motor 32, drive shaft 33, and array bevel gear assembly 34 work together to drive array cross shaft 31 to rotate. The rotation of cross shaft 31 adjusts the angle of rotating block 253 and nozzle 254 through sleeve 252. During this process, drive shaft 33 drives positioning disk 35 to rotate. After nozzle 254 rotates to a suitable angle, electric push rod 36 drives positioning pin 37 to insert into positioning groove on the side of positioning disk 35 to lock the angle of nozzle 254. When strip steel passes through spraying component 25, liquid is supplied to bellows 255 and nozzle 254 through external liquid supply end. Nozzle 254 sprays pickling liquid and performs spray pretreatment on strip steel.
