Tyre surface is transported to the carcass surface by rear conveying device 4, front conveying device 3 successively, and deciliter press-roller device 1 is pressed together on the carcass surface with tread rubber.
Tread rubber is pressed together in the process on carcass surface, 301 pairs of tread rubbers of the carrying roller 300 of front conveying device 3 and front pressure roller apply a vertical clamping action power, meanwhile in the middle of the downward spreading tread rubber of roller 311 and with the tread rubber stretching of extending longitudinally.
In the present embodiment, the tread rubber after severing is shorter than the girth on carcass surface, by the downward spreading tread rubber of middle roller 311, it is stretched to the length that is complementary with the carcass surface perimeter.
For example, be 180 centimetres (brief note is A1) by cutting device 5 with the tread rubber severing, and the carcass surface perimeter is 185 centimetres, tread rubber length after namely stretching should reach 185 centimetres (brief note is A3), and the physical length that tread rubber is extended in drawing process is the variable (brief note is A2) of a dynamic change.
The master control system that Full-automatic tire surface laminating machine is equipped with is recorded storage with above-mentioned three kinds of length data, to realize following concrete control procedure.
Vertically extended by middle roller 311 spreadings after stretching, the physical length A2 of tread rubber strengthens gradually.
The rotary encoder 306 that use connects at roller carrier shaft 302 sides, the tread rubber physical length amount of note to by carrying roller 300 and front pressure roller 301 time.
Rotary encoder 306 often revolves the distance that turns around and be fed forward corresponding to tread rubber, and the number of turns of rotation is fed back to the physical length A2 that is converted into after master control system after tread rubber is extended stretching.
In the time of between tread rubber is through carrying roller 300 and front pressure roller 301, tread rubber drives carrying roller 300 rotations, this moment, master control system began to calculate the rotating cycle of rotary encoder 306, along with the downward spreading of middle roller 311, tread rubber physical length A2 from A1 little by little close to A3.
Middle 311 pairs of downward spreadings of tread rubber of roller or upwards be separated from switching between the tread rubber surface state, and middle roller 311 is applied to the pressure size on tread rubber surface, in the middle of driving by rotation cylinder 314, pressure roller swing arms 313 are regulated.
The adjusting of the displacement of rotation cylinder 314 drive rods and output dynamics, can realize by the adoption rate control valve, be that the adoption rate control valve is regulated rotation cylinder 314 air demands and supply gas pressure, and then form displacement that drive rod stretches out/bounce back and the size adjustment of the dynamics of output.
