Description

Technical Field

[0001] The utility model relates to the technical field of cold rolling mills, in particular to a reversible anti-entanglement guide plate for a six-roller cold rolling mill. Background Art

[0002] A cold rolling mill is a new type of equipment for cold-rolling steel bars. With the development of steel industry technology, the market has increasingly stringent requirements for cold-rolled strip products. Anti-entanglement guides serve as auxiliary equipment for rolling. Their function is to ensure that the strip can be threaded smoothly, prevent damage to the working rolls during roll winding, and prevent emulsion from remaining on the surface of the strip, thereby ensuring smooth rolling. An existing reversible cold rolling mill has emulsion spraying devices and anti-entanglement guides on both sides of the working rolls. The emulsion spraying device is located above the anti-entanglement guides. The emulsion spraying device mainly sprays emulsion onto the working rolls. When the emulsion stops spraying, the anti-entanglement guides extend to catch the residual emulsion dripping from the spray port.

[0003] According to the description of a reversible cold rolling mill anti-entanglement guide disclosed on the patent website (authorization announcement number: CN 219052457U), "The utility model discloses a reversible cold rolling mill anti-entanglement guide, including a guide body, a working roll, a strip, an emulsion injection device and a collection box. The two guide bodies are both located above the strip, and the strip moves through the middle position of the corresponding two working rolls. The two emulsion injection devices are respectively located above the corresponding guide bodies. A drive assembly is provided on the side of the two guide bodies away from each other. A guide groove is provided in the two guide bodies. An E-shaped chassis is fixedly installed on the bottom side of the guide body. Two lifting grooves are provided on the inner walls of both sides of the E-shaped chassis. Sliders are movably installed on the corresponding two lifting grooves. Two sets of cleaning rollers clean the emulsion rebounded on the strip, and then complete the cleaning of the emulsion remaining on the surface of the working roll and the strip, thereby preventing the formation of emulsion spots due to untimely cleaning of the residual emulsion, thereby ensuring that there will be no quality problems in the strip production."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During use, the utility model drives the two sets of cleaning rollers to rotate when the strip moves, and the two sets of cleaning rollers clean the emulsion rebounded on the strip, thereby completing the cleaning of the emulsion remaining on the working rollers and the surface of the strip, thereby preventing the residual emulsion from being cleaned in time and forming emulsion spots. However, in actual use, as the cleaning rollers are used for a long time, some impurities will adhere to the surface of the cleaning rollers. Since it is inconvenient to disassemble and replace the cleaning rollers in time, it is easy to affect the subsequent cleaning work of the strip, which has certain limitations. Therefore, it is necessary to improve a reversible anti-entanglement guide plate for a six-roll cold rolling mill to solve the above problems. Utility Model Content
