Embodiment 1

[0016] Embodiment 1, the number of fixed rollers is 1, the number of driving rollers is 7, the fixed rollers are arranged on the top of the roller driving device, and the remaining driving rollers are arranged on both sides of the fixed rollers and form a circular shape together with the fixed rollers. , the position of the center of the circle is provided with an interlocking plate, and the fixed roller, the driving roller and the interlocking plate are connected through a connecting rod. The power input shaft realizes the power input, and through the power distribution of the gear transmission and the cardan shaft, the drive of other drive rollers can be operated, and the number of drives can be selected according to actual needs (the roller expansion and contraction device described in the present invention only needs to There are 4 wheels with drive (including 1 fixed roller) to meet the triangle glue bonding operation. The more drive wheels, the higher the efficiency, but the

Abstract

The invention relates to a roller expansion and shrinkage device. The roller expansion and shrinkage device is characterized in that an expansion and shrinkage cylinder, a gear transmission device and a chassis are arranged on a support; a roller driving device is arranged on the chassis; a fixed roller and a driving roller are arranged in the roller driving device; the fixed roller is connected with the expansion and shrinkage cylinder; the gear transmission device is arranged between the driving roller and the fixed roller. When the roller expansion and shrinkage device disclosed by the invention is used, steel wire rings are uniformly tensioned through the roller driving device, power input is realized through a power input shaft of the fixed roller, and accordingly the driving for other driving rollers is operated through the distribution for the power of the gear transmission device and a universal transmission shaft; the driving amount can be selected according to practical requirements, and the steel wire rings are tensioned by adopting the fixed roller and the driving roller, so that the deformation of the steel wire rings can be reduced, and the manufacturing quality and production efficiency of tires are ensured.
