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 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.
Description
technical field [0001] The invention relates to the technical field of rubber pasting, in particular to a roller expansion and contraction device used on a triangle rubber pasting machine. Background technique [0002] At present, the apex glue needs to be bonded with the traveler on the sticking machine, and the traveler needs to be evenly tightened. However, in the prior art, during the tensioning process, because the expansion force cannot be controlled, and because the structure of the expansion and contraction mechanism is set Defects cause uneven tension and make the traveler deform during the tension process, thus affecting the quality of the tire and the efficiency of production. Contents of the invention [0003] The purpose of the present invention is to provide an improved roller expansion and contraction device, which can overcome some shortcomings in the prior art that the tension is uneven, making the traveler deform during the tensioning process, thereby aff...
