Description

Technical Field

[0001] The utility model relates to the technical field of steel coil flattening, in particular to a steel coil flattening mechanism. Background Technique

[0002] Steel coils, also known as coil steel, in the steel processing industry, for the convenience of production, improving efficiency and reducing labor intensity, the raw material steel used is pre-wound into cylindrical steel coils and stored on special loading racks to keep them in a reasonable controlled state. During the production process of steel coil materials, the cylindrical steel coils need to be continuously or intermittently unwound by an uncoiler or a flattening machine, and the flattened steel coils are cut into required sizes by cutting equipment.

[0003] By comparing a steel coil flattening machine for CZ steel production with the patent publication number CN216369596U, in this solution, this device flattens and straightens the uncoiled steel coil through the first pressure roller, the second pressure roller and the third pressure roller. However, before flattening the steel coil after uncoiling, the steel coil needs to be transported. During the transportation process, the surface of the steel coil may generate a certain amount of static electricity due to factors such as friction, and thus the static electricity may adsorb small particles such as iron filings on the surface of the steel coil. Therefore, when the surface of the steel coil is squeezed against the pressure roller during flattening, due to the presence of a certain amount of iron filings on the surface of the steel coil, the squeezed iron filings may cause certain indentations on the surface of the steel coil, causing certain damage to the surface and reducing the production quality of the steel coil.

[0025] The present utility model will be further described below in conjunction with the accompanying drawings:

[0026] As Figures 1-5 shown, a steel coil flattening mechanism includes a bottom plate 100 and an uncoiling mechanism for uncoiling the steel coil. The uncoiling mechanism is located on the front side of the bottom plate 100. It further includes a flattening mechanism for flattening the steel coil, and the flattening mechanism is located on the rear side of the bottom plate 100.

[0027] In this embodiment: The uncoiling mechanism includes a support plate 301 fixedly arranged on the front side of the bottom plate 100. A placing roller 303 is rotatably installed at the upper end of the support plate 301. An uncoiling motor 302 is installed at the rotating end of the placing roller 303.

Then drive the pressing cylinder 308 to drive the rotating frame 309 to move downwards to drive the pressing shaft 310 to move downwards. The pressing shaft 310 abuts against the outer side of the steel coil, thereby preventing the steel coil from expanding outwards and causing danger.

[0029] In this embodiment: The flattening mechanism includes a support frame 201 arranged at the rear side of the bottom plate 100, a flattening assembly for flattening the steel coil, and a cleaning assembly for cleaning the surface of the steel coil before flattening.

[0030] The cleaning assembly includes a connecting frame 204 arranged at the front side of the support frame 201. A telescopic cylinder 205 is installed at the upper end of the connecting frame 204. A water spraying tank 206 is fixed to the telescopic end of the telescopic cylinder 205. A scraper 207 is fixed to the lower end of the water spraying tank 206. The scraper 207 is triangular with the tip facing the front side. A water spraying assembly is arranged on the water spraying tank 206. The water spraying assembly is used for spraying water while the scraper 207 cleans the surface of the steel coil.

[0031] The water spraying assembly includes a plurality of nozzles 208 installed at the upper end of the water spraying tank 206 near the scraper 207. A water receiving tank 211 is arranged below the support frame 201. A filter screen 212 is installed in the water receiving tank 211. A water discharging bin 210 is installed at the lower end of the support frame 201. The two water inlets of the water discharging bin 210 are located on both sides of the support frame 201. A plurality of overflow holes are formed in the side wall of the water discharging bin 210. A water pump 209 is arranged on the side wall of the support frame 201. A suction pipe is connected between the water pump 209 and the bottom end of the water receiving tank 211. A telescopic water delivery pipe is connected between the water pump 209 and the water spraying tank 206.

[0032] The flattening assembly includes two symmetrical connecting plates 213 arranged at the rear side of the support frame 201. A threaded rod 214 is rotatably installed between the connecting plate 213 and the support frame 201. A lifting motor 215 is installed at the rotating end of the threaded rod 214. A lifting frame 216 is slidably installed between the two connecting plates 213. The lifting frame 216 is in threaded connection with the threaded rod 214. A plurality of upper pressing rollers 217 are rotatably installed at the lower end of the lifting frame 216. The plurality of upper pressing rollers 217 are driven by a chain.

The plurality of lower pressing rollers 219 are driven by a chain. Rotating motors 218 are installed at the rotating ends of both the lower pressing rollers 219 and the upper pressing rollers 217. The rotating directions of the two rotating motors 218 are opposite. A limiting assembly is arranged at the front side of the support frame 201. The limiting assembly is used for straightening and positioning the position of the steel coil during transportation.

[0033] The limiting component includes a chute arranged on the front side of the support frame 201. A slide bar 202 is fixed in the chute. Two symmetrical guide plates 203 are slidably mounted on the slide bar 202. A limiting spring is connected between the guide plate 203 and the end of the slide bar 202. The guide plate 203 is inclined. An opening facing forward is formed between the two guide plates 203 in a V shape. Guide wheels are rotatably mounted on the side walls of the guide plates 203 to reduce the friction with the steel coil. Before flattening the steel coil, the cleaning component drives the scraping plate 207 to move downward to abut against the upper surface of the steel coil. Then, while the steel coil is transported backward, the scraping plate 207 scrapes off small particles such as impurities on the surface of the steel coil. With the action of the water spraying component, water is sprayed while scraping the surface of the steel coil. Under the interaction of the water flow and the scraping plate 207, impurities with a large adhesion force on the surface of the steel coil are scraped off, and at the same time, the surface of the steel coil is de-electrified, reducing the adsorption of small particles on the surface of the steel coil by the adsorption characteristics of static electricity during later transportation, improving the flattening accuracy of the steel coil and the production quality.

[0034] Working principle: First, place the steel coil to be processed on the placing roller 303. Then drive the oil cylinder 307 to drive the slide plate 305 to move towards the inner support plate 304, so as to drive the multiple wedges 306 on the slide plate 305 to squeeze with the multiple wedges 306 on the inner support plate 304, and then drive the multiple inner support plates 304 to extend outwards to tightly hold the steel coil. Then drive the lower pressing air cylinder 308 to drive the rotating frame 309 to move downward to drive the pressing shaft 310 to move downward. The pressing shaft 310 abuts against the outer side of the steel coil to prevent the steel coil from expanding outwards and causing danger.

[0035] Subsequently, drive the lifting air cylinder 312 to drive the support table 313 to lift the end of the placing roller 303 away from the oil cylinder 307 to support the placing roller 303. Drive the uncoiling motor 302 to drive the placing roller 303 to rotate, so as to uncoil the steel coil on the placing roller 303. One end of the steel coil moves backward and first squeezes the two guide plates 203 on the front side of the support frame 201, driving the two guide plates 203 to move away from each other. The two guide plates 203 after moving away from each other clamp and limit the two ends of the steel coil, and at the same time straighten the steel coil, so that the position of the steel coil does not shift during transportation. The steel coil continues to move backward along the upper front direction of the support frame 201.

[0036] Then, drive the telescopic cylinder 205 to drive the water spraying tank 206 to move downward, driving the scraper 207 to move downward, so that the scraper 207 abuts against the upper surface of the steel coil. While the steel coil moves backward, the scraper 207 scrapes the upper surface of the steel coil, and then uses multiple nozzles 208 at the upper end of the water spraying tank 206 to spray water on the surface of the steel coil. Combining with the scraping of the scraper 207 on the surface of the steel coil, the iron filings or small particles adhered to the surface of the steel coil are scraped to both sides of the scraper 207 and fall into the water sump 210. At the same time, due to the fact that the surface of the steel coil gets wet, the generation of static electricity on the surface of the steel coil is reduced, and it is less likely that the steel coil will adhere to small particles such as iron filings on the surface again during transportation and is not easy to clean. Subsequently, the scraped wastewater and waste chips fall onto the filter screen 212 at the upper end of the water receiving tank 211 through the water sump 210. The filter screen 212 filters the waste chips on the filter screen 212, and the filtered wastewater is pumped into the water spraying tank 206 by the water pump 209 again for recycling.

[0037] The cleaned steel coil continues to move backward. Drive the lifting motor 215 to drive the threaded rod 214 to rotate, drive the lifting frame 216 to move downward, and drive multiple upper pressing rollers 217 to move downward to abut against the upper surface of the steel coil. Thus, the steel coil is pressed tightly by multiple upper pressing rollers 217 and multiple lower pressing rollers 219. Drive the rotating motor 218 to drive multiple lower pressing rollers 219 to rotate in the opposite direction to the upper pressing rollers 217 to drive the steel coil to move backward, and at the same time perform a stretching and flattening operation on the steel coil, thereby completing the flattening of the steel coil.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
