Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

The back press roll device of the forming machine comprises a turbine box 1 and a rotating arm 3 connected with a turbine shaft 2 of the turbine box 1, the rotating arm 3 comprises a base 14 connected with the turbine shaft 2, one end of the base 14 is provided with a hollow cylindrical arm 16 extending vertically upwards, the base 14 and the cylindrical arm 16 are of an integral structure, a rotating shaft 4 is installed in the cylindrical arm 16, the top of the rotating shaft 4 is located outside the cylindrical arm 16 and provided with a press roll shaft 5, the press roll shaft 5 is connected with a press roll 6 through a bearing, the bottom of the rotating shaft 4 is located outside the cylindrical arm 16 and provided with a backup wheel connecting rod 7, the backup wheel connecting rod 7 is connected with a backup wheel 8, and a piston mechanism used for driving the rotating shaft 4 to rotate is installed on the rotating arm 3.

The specific structure of the piston mechanism is as follows: the piston mechanism comprises a shell 15 and a cavity 9 arranged in the shell 15, a piston 10 is arranged in the cavity 9, the piston 10 is connected with a rack 11, the rack 11 is meshed with a gear 12, and a rotating shaft 7 is arranged on the circle center of the gear 12;

the worm gear case 1 is connected with a shaping plate 17 through a fixing plate 10, the shaping plate 17 is positioned above the worm gear case 1 and is parallel to the upper surface of the worm gear case 1, and the idler wheel 8 is contacted with the side wall of the shaping plate 17; because the drum shoulder of the forming drum has a certain curve profile, when the pressing roller 6 presses the curtain cloth at the drum shoulder, the pressing roller 6 is required to be ensured to be always consistent with the normal direction of the curve at the pressing part when pressing the drum shoulder, thereby ensuring compaction and compaction. In order to ensure that the movement track of the compression roller 6 is close to the drum shoulder curve, a template 17 is arranged on the outer side of the turbine box 1, a wheel-leaning connecting rod 7 is leaned on the template 17 and used for controlling the rolling track of the compression roller 6 and simultaneously achieving coordinated and coherent control with the actions of advancing, retreating, left-right moving of the rotating arm 3, so that the comprehensive movement track of the compression roller 6 is the same as the drum shoulder curve, the drum shoulder is compacted and pressed firmly without air leakage, and the tire quality is ensured;

a spring 13 is sleeved outside the rack 11, the bottom of the spring 13 is in contact with the piston 10, and the top of the spring 13 is in contact with the top wall of the chamber 9; the press roll 6 is a cup-type press roll.

During operation, the piston 10 drives the rack 11 to move, and the rack 11 drives the gear 12 to rotate, so as to drive the rotating shaft 7 to rotate, and the compression roller 6 at the upper end of the rotating shaft 7 rotates. The whole rotating arm 3 is arranged on the turbine box 1, and when the worm wheel shaft 2 rotates, the whole pressing roller 6 is driven to rotate to a required position as required for rolling. When the compression roller 6 leans against the drum, when the rolling surface has uneven height difference, the compression roller 6 can be rotated by a certain reaction force, and because the bottom of the compression roller 6 is finally connected with the piston 10, compressible gas is arranged in the piston 10, and the spring 13 is arranged, a certain buffer effect can be achieved, the compression roller 6 can be compacted and firmly pressed, and the problem that the tire blank is damaged by hard collision of a stress can be avoided.
