Description

Technical Field

[0001] The utility model relates to the technical field of coil material feeding, in particular to a fixture for quickly switching tube cores. Background Art

[0002] When die-cutting materials, the coil is sleeved on the conveying shaft for film material conveying. The conveying shafts on the existing production lines are all small-sized shafts, and the outer diameter of the conveying shaft is generally 3 inches. With the increase in the requirements for the curling degree of the coil, some coils are wound with 6-inch or larger sleeves, which requires the coil corresponding to the large sleeve to be sleeved on the small-sized conveying shaft. A switching tube core jig must be used for reliable sleeve assembly. The existing switching tube core jig processes the corresponding annular metal sleeve according to the size to be expanded, and the inner ring of the annular metal sleeve and A tensioning mechanism needs to be set on the outer ring, and the annular metal sleeve is set at the corresponding position in the length direction of the conveying shaft. Then the large sleeve is put on the corresponding annular metal sleeve, and then the tensioning mechanisms corresponding to the inner ring and the outer ring are inflated and tightened, so that the entire mechanism can convey the film material normally. When the large sleeve needs to be removed, the tensioning mechanism is deflated to complete the removal of the large sleeve. In the process of loading the large sleeve coil, since the annular metal sleeve is relatively heavy, mechanical equipment is required to assist in loading, which makes the loading operation of the large sleeve coil complicated; therefore, it is urgently needed to develop a lightweight and fast switching tube core fixture.
