The smart tire inner tubes and flaps filling machines, independently researched and developed by Qingdao Kelida Machinery Manufacture Co., Ltd., were delivered to Prinx Chengshan (Shandong) Tire Co., Ltd. on December 20, 2018. Thus, there are three major domestic tire companies that have ended the history of manual filling of inner tubes and flaps during the truck tire production. 

The mounting speed of this machine of Qingdao Kelida is 100 tires per hour, that is, the mean time between two contiguous tires delivered at the transport rack is no more than 36 seconds. When it is connected with the automatic cover tire sorting line, only one person is required for operating the complete machine. The flap and inner tube loaded into the tire cover are evenly distributed without folding up. Even if there are some flaps turning up, it occurs less than two times among the whole circle with each one no more than 120mm. Thus the success rate of tire mounting is 99% and there is no damage on the tire carcass and no waste products produced.  

The complete machine works automatically and intelligently for 24-hour continuous normal operation in 3 shifts without manual intervention. It can automatically scan the bar code on the cover tire to distinguish the tire model and deploy the corresponding control program accordingly and automatically identify the yellow weight balance marks on the cover tire to timely convert the angle on its center with angle deflection of no more than ±4°. The noise peak of the complete machine during the normal operation is no more than 75dB.

The machine that sent to Chengshan Tire this time is said to apply to more than 10 types of truck radial tires. With high production efficiency, this machine has aroused interests of many tire companies and business negotiations are going on with four big tire companies.
