Embodiment Construction

[0031] Example, refer to figure 2 and image 3 ,in figure 2 It is a structural schematic diagram of the mechanical turning-up device of this embodiment after the turning-up is finished, image 3 It is a structural schematic diagram of the shrinkage state of the turn-up rod of the mechanical turn-up device of this embodiment.

[0032] Such as figure 2 , image 3 , The mechanical turn-up device of this embodiment includes a number of turn-up rods 4 , sliding sleeves 2 , drive ring 1 , swing arm 5 and drive link 3 .

[0033] The number of the turn-up rods 4 can be determined according to the specifications of the tire. In this embodiment, the number of the turn-up rods 4 is 12, and each turn-up rod 4 is equipped with a roller 4-1 at one end, and the other end is hinged on the pendulum. on arm 5. The sliding sleeve 2 is sleeved on the main shaft 6, and a plurality of slide rails 2-1 are arranged on it, and the number of the slide rails 2-1 is corresponding to the number o...

Abstract

Provided is a mechanical turn-up device, comprising several turn-up rods, a slide sleeve sleeved on a main shaft, a drive ring connected on a case, and a turn-up rod drive unit used to drive each turn-up rod to turn up and return to position. The turn-up rod drive unit is arranged between the slide sleeve and the drive ring. The present invention drives turn-up rods to turn up via a mechanical drive unit, thereby overcoming defects brought about by the use of a bladder drum, in addition to achieving a large turn-up height in a limited space, and adapting to tyres with different specifications.

Description

technical field [0001] The invention relates to a front and back wrapping device in the tire building process. Background technique [0002] The two-stage forming machine for radial tires includes a one-stage forming machine and a two-stage forming machine. The one-stage forming machine places the inner liner, carcass cord, reinforcing layer, bead, sidewall and other components in a certain order on the one-stage forming drum. Above, the mechanical device that forms the carcass tube through operations such as wrapping, bead buckling, turning up, and rolling. The carcass tube will then enter the second-stage forming machine through manual or mechanical devices, and finally form the embryo. [0003] figure 1 Shown is a typical structural layout of a one-stage forming machine in the prior art, which mainly includes a chassis 2, a drum 1, left and right front and back packaging devices (31, 32), and a feeding device 4. The main process diagram is as follows: [0004] Step 1....
