Description

Tape winding device

technical field

The utility model relates to an adhesive tape winding device applied in the field of tire manufacturing.

Background technique

Tires are the main action components of motor vehicles. The quality of tire processing determines the stability of its performance. Whether it meets the requirements of processing standards will directly determine the safe use of motor vehicles. At present, in the rubber tire processing process, each part of the semi-finished tire needs to be bonded on the forming drum, such as the winding and bonding process of the adhesive tape on the belt layer bonding drum.

The existing tape winding process adopts a pressure roller laminating device. With the help of manual positioning, the tape is first wound on the belt drum, and then the belt drum is driven by a motor to rotate, and passes between the pressure roller and the belt drum. The squeezing force winds the tape around the drum. When the winding process is finished, the adhesive tape is cut off, and the thread ends remaining after winding also need to be cut off by people to prepare for the next winding process.

The above-mentioned existing tape winding device and process need to be completed by manual operation and assistance. The positioning of the winding device, the bonding of the tape on the drum, and the treatment of the thread ends must be completed manually, which not only affects the execution of the processing technology, but also prolongs the time of the winding process. It is also difficult to maintain uniform control of tape winding quality in the process of large-volume tire processing.
