Description

Technical Field

[0001] The utility model belongs to the technical field of wide-width stainless steel production and manufacturing, and particularly relates to a device for controlling dirty prints on the surface of a wide-width stainless steel panel. Background Art

[0002] During the production and processing of stainless steel strips, the residual liquid on the surface of the steel strips needs to be quickly cleaned before and after laminar cooling and rolling to avoid water stains, black spots and other surface dirt on the surface. The existing steel strip surface cleaning devices have the following technical problems during use: 1) Gas is used for purging. During the purging process, liquid water droplets will be blown up by the gas, causing them to splash on the surface of the steel strip, and it is impossible to separate the water droplets from the surface of the steel strip in the first time, which has a local impact on the surface temperature of the steel strip; 2) In the existing purging devices, the purging heads are mostly arranged parallel to the steel strip, resulting in the residual water stains on the surface of the steel strip, which will gather and roll along the steel strip during the purging process. Especially on the surface of wide stainless steel, due to its wide cross-section, the purging heads arranged parallel to the steel strip cannot quickly blow the water stains away from the surface of the steel strip, resulting in water marks and other dirt on the surface of the steel strip.

[0003] After searching, the prior art CN218133757U discloses a blowing device for improving the surface quality of steel strip, comprising a steel strip conveying device, two sets of mounting seats are symmetrically installed on opposite sides of the steel strip conveying device, and a blowing pipe is detachably installed between the two sets of mounting seats, and the blowing pipe is connected to at least two nozzles facing the steel strip conveying device, and the mounting seat comprises a lower mounting seat, and the lower mounting seat is detachably connected to an upper mounting seat on a side away from the steel strip conveying device, and an arc groove that cooperates with the blowing pipe is provided at one end of the upper mounting seat and the lower mounting seat that are close to each other, and the above technical scheme is provided with a blowing pipe and a nozzle above the steel strip conveying device to blow and clean the processed steel strip surface, and at the same time, it is convenient to replace the blowing pipe; however, the above technical scheme has the following technical problems during use: because the nozzle is arranged parallel to the steel strip, when it blows the steel strip surface, impurities such as surface oxide scale particles and water stains will roll on the steel strip surface, and it is difficult to quickly detach from the steel strip surface, resulting in the gathering of water stains and the accumulation of particles, thereby producing water marks, black spots and other dirty marks on the steel strip surface, affecting the surface quality.

[0004] For another example, the prior art CN220195949U discloses an external blowing device for a strip steel rolling mill, comprising two support frames, a lifting assembly is arranged between the two support frames, the lifting assembly comprises two bidirectional screws, two first motors and four blowing assemblies, the two bidirectional screws are respectively rotatably arranged on the inner walls of the two support frames through sealed bearings, and the surfaces of the two bidirectional screws are threadedly connected to two cross plates through screw nuts; the rotation of the two first motors will drive the four cross plates to move, and the four cross plates all move in the direction close to the strip steel, the four cross plates drive the four moving frames and four connecting cylinders to move, and the four connecting cylinders drive a number of first nozzles and a number of second nozzles to move, so that the number of first nozzles and the number of second nozzles can automatically approach the strip steel of different thicknesses to ensure the blowing effect of the emulsion; however, the above technical solution has the following problems during use: 1) the middle connection part of the two groups of blowing assemblies lacks nozzles, resulting in poor blowing effect on the middle part of the steel strip; 2) the blowing assembly can adjust the angle to blow the surface of the steel strip, but it will cause splashing of the liquid mixture during the blowing process, affecting the surrounding environment and easily causing pollution. Summary of the invention

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a device for controlling dirty marks on the surface of a wide stainless steel panel. By arranging an air blowing head perpendicular to the movement direction of the steel strip, during the blowing process for wider stainless steel, impurities such as particles and water stains on the surface of the steel strip can be quickly blown away along the cross-sectional direction to avoid impurities such as water stains mixed with particles rolling and gathering on the surface of the steel strip to produce surface dirty marks, thereby ensuring the cleanliness of the wide stainless steel surface and improving the quality of the stainless steel.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A device for controlling dirty marks on the surface of a wide stainless steel panel comprises a support frame, a guide rod, an electric telescopic rod I, a sliding base, a purge pipe, an air blowing head, a hose I, a bellows, a blower, a protective box, an electric telescopic rod II, a protective cover, a movable seat, a water-absorbing sponge, a water-drawing pipe, a motor, a hose II, a collection box, and a negative pressure blower. The support frame is provided with a guide rod, and two sets of sliding bases are movably installed on the guide rod. One side of the sliding base is fixedly connected to one end of the electric telescopic rod I, and the other end of the electric telescopic rod I is fixedly installed on the support frame. A purge pipe is provided on the sliding base, and a plurality of air blowing heads are provided on the purge pipe. One end of the purge pipe is closed, and the other end passes through the hose I. A ventilation box is fixedly connected, one side of the bellows is fixedly connected to the blower, a support frame is provided with a slide rail on the top of which one end of an electric telescopic rod II is fixedly installed, the other end of the electric telescopic rod II is fixedly connected to a protective cover, both ends of the protective cover are fixedly installed on a movable seat, one side of the movable seat is movably engaged and installed on a slide rail on one side of the support frame, a water suction pipe is movably installed on the movable seat, a water-absorbing sponge is wrapped around the outside of the water suction pipe, a number of water-permeable holes are opened on the water suction pipe, one end of the water suction pipe is closed and fixedly connected to the output end of the motor, the motor is fixedly installed at one end of the movable seat, the other end of the water suction pipe is connected to a collection box through a rotating joint in the movable seat and cooperates with a hose II, and the top of the collection box is fixedly connected to a negative pressure fan.

[0008] The support frame is provided with an electric telescopic rod III fixedly installed at the bottom of one side of the guide rail, and a scraper is fixedly installed at the other end of the electric telescopic rod III. The scraper can scrape water droplets from the lower surface of the steel belt on the roller to ensure that no water stains remain and control dirty marks on the surface of the steel belt.

[0009] A protection box is fixedly installed on one side of the support frame. When the steel strip is purged by the purging pipe through the air blowing head, the liquid blown off can fly into the protection box to avoid splashing.

[0010] The inner side of the protective cover is provided with a squeezing plate I, a squeezing plate II, and a squeezing plate III in sequence. The squeezing plate I, the squeezing plate II, and the squeezing plate III have different contact angles with the water-absorbing sponge, which can generate different pressures on the water-absorbing sponge. When the water-absorbing sponge rotates with the water suction pipe, the water-absorbing sponge can be squeezed step by step in batches, and the squeezing and drainage work can be completed more thoroughly, thereby ensuring the recycling of the water-absorbing sponge.

[0011] The air blowing head on the blowing pipe is installed perpendicularly to the moving direction of the steel strip. The air blowing head installed perpendicularly to the steel strip can quickly blow water stains on the surface of the steel strip out of the surface of the steel strip, thereby preventing the water stains from gathering and rolling on the surface of the steel strip during the blowing process, resulting in surface defects such as water marks and dirty marks.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1) The purge head on the purge pipe is installed vertically to the steel strip, which can gradually purge the surface of the steel strip along the cross-section of the steel strip, so that water stains, particles and other impurities on the surface of the steel strip are blown out of the surface of the steel strip in the shortest path, achieving the purpose of rapid cleaning, avoiding the accumulation and rolling of water stains, particles and other impurities on the surface of the steel strip during the purge process, and avoiding the generation of surface dirty defects such as water marks and black spots on the surface of the steel strip, which greatly improves the surface quality of the steel strip, increases the pass rate, and reduces the subsequent processing costs;

[0014] 2) During the process of blowing the steel strip surface, a protective box is fixedly installed on one side of the support frame. When the blowing pipe blows the steel strip through the blowing head, the blown liquid can fly into the protective box to avoid splashing of the liquid mixture, effectively ensuring the cleanliness of the surrounding environment and reducing pollution to the workshop environment;

[0015] 3) A water-absorbing sponge is arranged behind the purge pipe. The electric telescopic rod II drives the water-absorbing sponge to contact the upper surface of the steel belt through the movable seat to absorb the remaining small water stains. During the absorption process, the water pumping pipe drives the water-absorbing sponge to rotate in the direction of the arrow in the figure. When rotating, the water-absorbing sponge contacts the extrusion plate I, the extrusion plate II, and the extrusion plate III in turn. The extrusion plate I, the extrusion plate II, and the extrusion plate III have different contact angles with the water-absorbing sponge, which can produce different pressures on the water-absorbing sponge. When the water-absorbing sponge rotates with the water pumping pipe, the water-absorbing sponge can be squeezed step by step, and the squeezing and drainage work can be completed more thoroughly to ensure the recycling of the water-absorbing sponge. The water generated after squeezing will enter the water pumping pipe through the water permeable hole, and be pumped into the collection box for centralized storage with the negative pressure fan. The water stains on the lower surface of the steel belt are directly scraped off by the scraper. By treating the upper and lower surfaces of the steel belt, the remaining small water stains on the surface of the steel belt can be further removed to avoid the small water stains in the subsequent work to produce rust spots and other dirty marks, further ensure the surface quality of the steel belt, and improve the qualified rate of the steel belt.
