Description

Technical Field

[0001] The invention belongs to the field of mechanical processing equipment, and in particular relates to an online automatic wiping device. Background Art

[0002] With the rapid development of the automobile industry, automobiles have become an important means of transportation for people's daily life. People are also paying more attention to the corrosion resistance and durability of automobiles. Galvanized steel sheets can meet this requirement well and are widely used in automobile manufacturing. Zinc is a relatively active metal with a standard electrode potential negative to iron. When plated on the surface of ordinary steel, it has the function of sacrificial anode protecting cathode, thereby extending the service life of ordinary steel in water or humid air. Hot-dip galvanized sheet, that is, steel sheet with a zinc layer on the surface, is a large category of steel products and an important industrial material. Because of the zinc layer attached to the surface, it has a strong antioxidant ability and can enhance the corrosion resistance of the device. Therefore, it is widely used in light industry, electronics, machinery and other fields.

[0003] The production process of galvanized sheet is long and the production process is complicated. Its main production process is as follows: coiling → double uncoiling → cutting head and tail → welding → alkali cleaning → primary brushing → electrolytic cleaning → secondary brushing → hot water rinsing → hot air drying → entrance looper → continuous annealing → hot dip galvanizing (ceramic zinc pot) → air knife purging (introduction) → air cooling after plating → water quenching → leveling machine (reserved) → stretching straightener → passivation treatment (reserved for fingerprint resistance) → exit looper → oiling → shearing → coiling → unloading → weighing → packaging. In the production and processing of hot-dip galvanized sheet, due to factors such as rolling equipment, materials and processes, some obvious defects often appear on the surface of hot-dip galvanized sheet, such as rolling injury, inclusions, heavy skin and holes. These complex defects not only destroy the flatness of the surface of hot-dip galvanized sheet and affect the appearance, but also make the hot-dip galvanized sheet very easy to be corroded and worn, seriously reducing the quality of hot-dip galvanized sheet. In addition, the marks left by the oilstone when checking the unevenness of the sheet metal have no effect on the electrophoretic paint film on cold-rolled steel and ordinary hot-dip galvanized plates, but obvious electrophoretic streaks will appear on electro-galvanized pre-phosphating plates. Therefore, when checking the pre-phosphating plates, it is necessary to use 320# or above sandpaper to thoroughly polish the surface defects and oilstone marks.

[0004] With the development of online detection technology and online grinding technology, some hot-dip galvanized sheet manufacturers such as Baosteel have acquired online defect detection and grinding technology, which has greatly improved the defect recognition rate, production efficiency and product quality. If the dust and residues generated after surface grinding are not handled thoroughly and in a timely manner, new defects will be generated in the electrophoresis process, seriously affecting product quality. Therefore, in response to the above problems, this technical solution provides an online automatic wiping device. Summary of the invention

[0005] The present invention provides an online automatic wiping device, which can timely remove oil stone marks, dust and residues generated during the online grinding process of hot-dip galvanized plates without stopping the machine or reducing the speed, thereby improving production efficiency and ensuring product quality. The device is suitable for a continuous production line of hot-dip galvanized plates and solves the problems in the background technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] An online automatic wiping device of the present invention comprises a frame;

[0008] A crossbeam is provided at the top of the frame, and lifting cylinders are installed at the bottom of the left and right sides of the frame. The top of the lifting cylinder is connected to the vertically arranged columns, and the two ends of the crossbeam are respectively connected to the corresponding columns, and the two ends of the crossbeam are respectively connected to the columns. Two driving rollers arranged side by side on the left and right are provided below the crossbeam, and two rubber-coated wiping rollers are provided below the driving rollers, and two free rollers are provided above the driving rollers;

[0009] The free roller, the driving roller and the ends of the rubber-coated wiping roller are installed on the crossbeam through roller brackets. A driving component is connected to the end of the driving roller. A rolled non-woven fabric is wound around the outside of the free roller. One end of the rolled non-woven fabric is wound downwardly around the outside of the rubber-coated wiping roller and then rolled up and wrapped around the outside of the driving roller.

[0010] Furthermore, the crossbeam includes a left crossbeam and a right crossbeam; the left crossbeam and the right crossbeam are detachably connected at one end, and the other ends are rotatably connected to vertically arranged rotating shafts, the rotating shafts are installed on the columns, and the bottom of the rotating shafts is driven and connected with a rotating cylinder, which drives the left crossbeam and the right crossbeam to swing outward and open or close inward and connect in turn through the rotating shafts.

[0011] During operation, the corresponding rotating shaft is driven to rotate by the rotating cylinder, and the left beam or the right beam on the rotating shaft rotates accordingly, which can push and control the left beam and the right beam to swing outward in turn, making it convenient for workers to remove the stained non-woven fabric roll wrapped around the outside of the driving roller or install the clean rolled non-woven fabric to the outside of the free roller. It is also convenient to replace or repair the free roller, driving roller, and rubber-coated wiping roller.

[0012] Furthermore, vertically arranged locking cylinders are provided on the columns on the left and right sides of the frame, and locking blocks are respectively provided at the opposite ends of the left crossbeam and the right crossbeam, and locking holes are opened on the locking blocks. After the left crossbeam and the right crossbeam are closed and spliced ​​inwardly and connected, the end of the locking cylinder is directly opposite to and can be movably extended into the locking hole on the locking block.

[0013] During operation, when it is necessary to use the rubber-coated wiping roller to wipe the surface of the steel belt, the lifting cylinder is controlled to drive the crossbeam down until the rubber-coated wiping roller contacts the surface of the steel belt, and the non-woven fabric on the rubber-coated wiping roller is used to wipe clean the oil stone prints, dust and residues generated during the grinding process of the surface of the steel belt running below. In order to prevent the rubber-coated wiping roller from shifting in the front and rear directions during the wiping process, the end of the locking cylinder is controlled to extend into the locking hole of the locking block to prevent the rubber-coated wiping roller from rotating in the front and rear directions around the rotating axis under force during the wiping process, thereby ensuring the smooth and normal progress of the entire wiping process.

[0014] Furthermore, the left crossbeam is connected to one of the free rollers, the driving roller, and the rubber-coated wiping roller through a roller bracket; the right crossbeam is connected to another free roller, the driving roller, and the rubber-coated wiping roller through a roller bracket; the two free rollers, the two driving rollers, and the two rubber-coated wiping rollers are detachably connected near one end.

[0015] Through the setting, the rotating cylinder drives the corresponding left and right beams to swing outwards and open in turn, and the two free rollers, the two driving rollers and the two rubber-coated wiping rollers are separated, and the left and right beams respectively drive the corresponding roller shafts located below to swing outwards and open, which makes it more convenient for the staff to operate and remove the stained non-woven fabric roll wrapped around the outside of the driving roller, install the clean rolled non-woven fabric to the outside of the free roller, or repair or replace the roller shaft.

[0016] Furthermore, after the two rubber-coated wiping rollers are connected, the roller surfaces have overlapping size areas.

[0017] By setting, it is ensured that the wiping working surfaces of the two rubber-coated wiping rollers can cover the entire strip.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) In this solution, the lifting cylinder drives the crossbeam down until the rubber-coated wiping roller contacts the surface of the steel belt, and the non-woven fabric wrapped around the surface of the rubber-coated wiping roller wipes away the oil stone marks, dust and residues generated during the grinding process of the surface of the steel belt running below;

[0020] (2) Through the cooperation of the driving roller, the free roller and the rubber-coated wiping roller, when working, the driving roller is controlled to rotate, and the clean non-woven fabric on the outside of the free roller is unwound and wound onto the rubber-coated wiping roller, which is convenient for subsequent continuous wiping. The non-woven fabric on the outside of the rubber-coated wiping roller with stains after wiping can be automatically recovered and rolled onto the surface of the driving roller;

[0021] (3) This device can timely and continuously remove the oil stone prints, dust and residues generated during the online grinding of hot-dip galvanized sheets without stopping the machine or slowing down the speed, thereby improving production efficiency and ensuring product quality. It is suitable for the continuous production line of hot-dip galvanized sheets and has good application prospects.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
