Why Does The Slip Shaft Heat Up?

The slip shaft is an important component on the lithium battery slitter (slitting machine). It is mainly used for the reel. Its main purpose is to manipulate the tension adjustment of the material during the winding process.

Its working principle is: the central air pressure slip shaft is a tension adjustment type slip shaft, and the slip ring is independently slipped. The slip shaft is centered on the precision air core ventilation main shaft. The piston is used to push the piston in the cavity, so that the shaft core generates friction torque between the friction member and the slip ring, which further drives the obliquely expanding piece on the inclined base. The radial direction expands, squeezing the take-up reel, and transmitting the torque of the take-up reel to achieve constant tension take-up.

The slip shaft sometimes has a fever, and if it is heated for a long time, it is easy to cause some malfunctions. The manufacturer of the slip shaft below tells you the cause of the fever.

First of all, the slip axis is ideal when starting to wind up. When going to the large diameter, you will obviously see that the speed of the coil is very different from the speed of the shaft, that is, the slip ring is always in the axis. Friction, this excessive friction produces a lot of heat, and even burns your hands when the situation is serious. If there is no looseness in the coil diameter in the case of large coil diameter, we need to adjust the speed ratio of the machine at this time, usually 1:1.1 is ideal, and it will be related to the winding. Material related.

Secondly, if you go to the big diameter path, there will be different tensions and deviations. At this time, you should first increase the air pressure, because the tension required for the large diameter is relatively large, when the tension we provide is not large enough. Under the circumstances, there will be a phenomenon of unevenness in the deviation, especially the loose phenomenon. At this time, the tension must be increased. Conversely, if the tension is too tight and the material is severely deformed, we should Turn the tension down.
In short, whether it is to increase the tension or adjust the tension, we have only one goal, which is to adjust the slip axis to an ideal slitting and winding state.
The slip axis is slightly heated under normal use conditions. If the hand touches the slippery shaft and the hand feels hot or feels hot, then we need to find out the reason, whether it is the speed ratio or the tension setting. Incorrect, both need to be considered to find out the problem and adjust the slip axis to the optimal use state.
