Cotton tape buffer early warning device

The utility model discloses a cotton tape buffer early warning device which is composed of a support, cotton tape buffer grooves and sensing devices. The cotton tape buffer grooves are fixedly formed in the support, the cotton tape buffer grooves are of an oblique J-shaped structure, and the number of the cotton tape buffer grooves is at least one. The sensing devices are arranged on the lower portions of the cotton tape buffer grooves. The sensing devices comprise supporting rods, supporting frames and limiting switches. The supporting rods are welded to the outer sides of the left side and the right side of each cotton tape buffer groove. The supporting frames are connected to the lower portions of the left side and the right side of each cotton tape buffer groove in a threaded mode. The limiting switches are fixedly mounted on the supporting frames. A reinforcing plate which horizontally surrounds the outer side wall of each cotton tape buffer groove by a circle is arranged on the top of the outer side wall of the corresponding cotton tape buffer groove. The cotton tape buffer early warning device is arranged between a tape ironing machine and a tape winding machine, six cotton tapes are automatically controlled to be conveyed at the same time, the phenomenon that a plurality of cotton tapes are twined together is avoided, meanwhile, the idling phenomenon of the tape ironing machine and the tape winding machine is avoided, and therefore the working efficiency and the cotton tape quality are improved.
