Problems solved by technology
Because the lithium battery diaphragm itself is required to be very thin, and the broadband occupied by the belt 12 is removed, the width of the roller surface of the air shaft 2 will be more limited. How to control the tension of the air shaft 2 within the limited width is to ensure that the independent arm 1 important bottleneck of function

The invention belongs to the technical field of slitting machines and relates to an inflating shaft for an independent arm. The inflating shaft for the independent arm includes a hollow shaft fixed onthe independent arm, a supporting body and an inflating piston rod, wherein the supporting body is arranged outside the hollow shaft and can rotate around an axis of the hollow shaft, the inflating piston rod in the hollow shaft stretches out and draws back in the axial direction, a synchronous pulley is fixedly arranged on one side of the supporting body, and a front shroud is fixedly arranged on the other side of the supporting body; and the inflating piston rod abuts against a piston top sheet sealed in the front shroud, the piston top sheet is connected with a wedge ring sleeving outsidethe supporting body, a plurality of inflating bearing bushes are clamped between the wedged ring and the supporting body, the inflating bearing bushes are provided with an oblique plane matched with the shape of the wedged ring, and the axial motion of the wedged ring is switched to radial motion of the wedged ring through the oblique plane. According to the inflating shaft for the independent arm, the structure is compact, fixing and winding of a material coil are achieved, and the inflating shaft for the independent arm is very suitable for the winding operation of a narrow material belt.
Description
technical field [0001] The invention relates to the technical field of slitting machines, in particular to an air expansion shaft for an independent arm. Background technique [0002] The slitting machine is a device used to longitudinally cut strip materials. In the slitting process of the lithium battery separator, in order to avoid the slight difference in the thickness of each strip after slitting, the company designed an independent arm 1 structure, such as figure 1 and figure 2 shown. This independent arm 1 controls the tension of the fine material bands after slitting respectively, which can ensure that each thin material band can be wound tightly. The independent arm 1 is rewound by means of an inflatable shaft 2 driven by a motor 11 through a belt 12 . Because the lithium battery diaphragm itself is required to be very thin, and the broadband occupied by the belt 12 is removed, the width of the roll surface of the air shaft 2 will be more limited. How to contro...
