Description

Technical Field

[0001] The utility model specifically relates to the technical field of adhesive tape slitting, in particular to an adhesive tape slitting component with a deviation-correcting structure. Background Art

[0002] Adhesive tape is a strip of adhesive material that is widely used in daily life and many industrial fields. After production, the tape is generally produced in the form of a cylindrical tape mother roll. In order to adapt to different applications, the tape mother roll needs to be cut using a tape slitting machine. The tape slitting machine is a device used to cut wide tape materials into narrow tapes. The tape mother roll is driven by a rotating mechanism to rotate at a constant speed, and the tape mother roll is cut in cooperation with the same rotating slitting mechanism.

[0003] However, in practice, the slitting knives of the tape slitting machine are usually circular blades, which are arranged according to the required width spacing. When the tape passes through the knife, the blade will cut the tape into multiple narrow tapes. These blades can be fixed or adjustable, which is convenient for setting according to different slitting width requirements;

[0004] Since the slitting tool is equipped with multiple blades, the rotating blades will drive the tape mother roll to slit after contacting the tape mother roll, and the rotating blades will drive the tape mother roll to rotate. Since the tape mother roll is directly connected to the rotating roller, the tape mother roll is prone to axial deviation during rotation, resulting in spiral cutting between the blades and the tape mother roll, thereby affecting the slitting accuracy of the tape mother roll.

The inner ring of the installation bearing is interference fit with the two ends of the support rod 52, and the outer ring of the installation bearing is interference fit with the two ends of the outer sleeve 6.

[0031] In this embodiment, a shaft rod 53 is integrally provided on a side of the mother roll feeding rack 5 away from the extension rack 51 , and an end of the shaft rod 53 is movably connected to the triangular plate.

[0032] In this embodiment, the mother roll corrector 9 includes a positioning frame 92, a through hole 93 is opened at the center of the positioning frame 92, and guide rollers 94 are arranged in a circular array on the side of the through hole 93, and each guide roller 94 is movably connected to the positioning frame 92.

[0033] In this embodiment, the two sides of the positioning frame 92 are symmetrically fixedly connected with the connecting plates 91, and the side of the connecting plate 91 away from the positioning frame 92 is threadedly engaged with the threaded roller shaft 7;

[0034] The end of the threaded roller shaft 7 passes through the connecting plate 91 and is movably connected to the inner side of the supporting main frame 1 .
