Description

Technical Field

[0001] The utility model relates to the technical field of steel coil processing, in particular to a steel plate uncoiling device. Background Art

[0002] Steel coil, also known as coiled steel. Steel is hot-pressed or cold-pressed into a coil, which is convenient for storage and transportation. Steel coils are processed by uncoiling equipment and flattening equipment to produce steel plates that meet customer needs. When the steel coils are transported to the manufacturer for use, they need to be uncoiled. Uncoiling devices are one of the essential and important equipment in the metal processing industry.

[0003] Publication No. (CN214719503U) discloses an unwinding device for automatically pressing against a steel coil. After the steel coil is sleeved on the support roller, the staff energizes the roller body. After energization, the roller body generates magnetism. Since the magnetic poles of the roller body are opposite to the magnetic poles of the pressing plate, the roller body generates a magnetic repulsive force on the pressing plate, causing the pressing plate to move away from the roller body. Due to the restrictions of the extension rod and the clamping block, the pressing plate moves in the direction of the roller cross-sectional radius, that is, moves toward the inside of the steel coil, until it contacts and presses against the steel coil. This process compresses the buffer spring, which is compressed and accumulates elastic potential energy. The three pressing plates press against the inside of the steel coil at the same time, which plays a role in pressing and fixing the steel coil. After that, the staff installs the baffle and turns on the drive motor to start unwinding the steel coil.

[0004] When installing a new steel coil, the above device needs to remove multiple bolts on the three baffles respectively. After the steel coil is installed, the multiple bolts on the three baffles need to be reinstalled, which will affect the installation efficiency and needs to be improved. Utility Model Content
