Problems solved by technology
[0003] In the existing unwinding machine, every time the upper and lower winding shafts are replaced, the side guards of the machine need to be removed, and a block of equal height should be placed on it before replacement, especially when the reel is changed or the center is shifted during work. Prying and adjusting with manpower consumes a lot of manpower and material resources

The invention discloses an Oldham coupling and an unreeling machine using same. The unreeling machine using the Oldham coupling comprises a base, a magnetic powder brake, a reeling shaft, supports and the Oldham coupling; the magnetic powder brake is fixedly connected to the left side of the base; the support is respectively arranged at the left end and the right end of the base; the reeling shaft which sleeves the supports are connected with the magnetic powder brake through the Oldham coupling; the Oldham coupling comprises a semi-coupling-sleeve and a sliding block; the sliding block is in a butterfly shape; the center of the sliding block is provided with a limit hole; the sliding block is arranged inside the semi-coupling-sleeve; bilateral sides of the semi-coupling-sleeve are provided with gaps; the outer edge of the sliding block is adhered to the gaps on bilateral sides of the semi-coupling-sleeve. The unreeling machine using the Oldham coupling has the advantages of saving a large amount of time for replacing the reeling shaft and solving the problem of inaccurate positioning due to applications of the coupling.
Description
technical field [0001] The invention relates to a slider coupling and its application to an unwinding machine. Background technique [0002] The unwinding machine is an important part of the automatic production line, which mainly realizes the functions of coil positioning and clamping and circumferential step unwinding. When in use, when the coil is sent to the unwinder by the feeding car and lifted to an appropriate height, the two-way chuck of the unwinder automatically moves, stretching from the left and right directions to the coil material hole for positioning, after clamping properly , to stop the axial movement. When the unwinding signal is issued, the coil can rotate smoothly to release the material. [0003] In the existing unwinding machine, every time the upper and lower winding shafts are replaced, the side guards of the machine need to be removed, and a block of equal height should be placed on it before replacement, especially when the reel is changed or the...
