Description

Technical Field

[0001] The utility model relates to the technical field of can cover production, in particular to a coil unwinder used for can cover production. Background Art

[0002] The uncoiler is a special equipment for leveling metal plates. It is used for leveling steel plates and uneven plates. It can be used to form uncoiler, leveling, shearing production lines and other plate product production lines according to relevant configurations. At present, most of the existing uncoiler structures, such as the uncoiler disclosed in the Chinese patent authorization announcement number CN210450370U, include a frame with a rotatable winding roller set on the frame.

[0003] The metal coil is installed on the roll, and the metal coil is limited by the cooperation of the baffle and the clamping plate to realize the conveying of the coil.

The No. 1 power element 3 drives the support plate 2 to rotate, and the material strip on the metal coil is conveyed to the stamping equipment through the guide wheel 5 and the feeding wheel 6. The device does not require the metal coil to be aligned, but only needs to adjust the rotation speed of the support plate 2 to maintain the stable conveyance of the material strip, which can effectively improve the work efficiency.

[0033] In the embodiment, Figure 1 , Figure 2 , Figure 4 As shown, the mounting arm 4 is provided with a mounting block 9, the mounting block 9 is provided with a through hole 10, a threaded hole 11 is provided on one side of the through hole 10, and the mounting block 9 is provided with a connecting rod 12 for cooperating with the through hole 10, and the bottom end of the connecting rod 12 is circumferentially matched with the pressure plate 8.
