[0002] With the development of the rubber industry, more and more people are pursuing low-carbon, environmentally friendly, low-energy, low-noise, zero-pollution, high-efficiency, and low-cost rubber equipment processes to produce rubber products. This is also the development trend of today's rubber equipment technology level.

[0003] The lamination of apex rubber and cloth-wrapped steel rim is an important process in tire molding. At present, most domestic tire manufacturers still use manual lamination in the production process of all-steel truck tires, which has the defects of high labor intensity, low production efficiency and unstable product quality. Or single-station automation also has the problem of low efficiency. The current lamination plates are generally less versatile. Different lamination plates need to be designed for different products, which increases production costs.

[0004] CN201910276361.1 discloses a laminating disk assembly device of an automatic apex glue laminating machine, which includes a base, a rotating base is installed laterally on the base, and a sliding guide mechanism and a transverse driving mechanism are arranged between the rotating base and the base; a double-station switching seat is installed on the rotating base, and a rotation positioning mechanism and a switching seat rotation driving mechanism are arranged between the double-station switching seat and the rotating base; two station laminating rings are symmetrically installed on the double-station switching seat, and the station laminating ring includes a mounting ring, and a coaxial rotating disk is also rotatably installed on the mounting ring, and a rotating disk rotation driving mechanism is arranged between the rotating disk and the mounting ring; although the device has two stations, it cannot simultaneously perform the two steps of loading and unloading wire rings and apex glue laminating.
