Mechanical assembly drum, anti-package equidistant control device and control method thereof

Abstract

The invention discloses a mechanical assembly drum, an anti-package equidistant control device and a control method thereof. The anti-package equidistant control device comprises the mechanical assembly drum which comprises anti-package rod devices arranged on two sides of a green tire and a driving device which controls the anti-package rod devices to operate; each of the anti-package rod devices comprises an anti-package rod (3) and a pressure sensor (4) for detecting stress of the anti-package rod (3). The mechanical assembly drum also comprises a comparing device for pressure values of the pressure sensors (4) on the anti-package rods on two sides. The comparing device is in communication connection to the driving device. The anti-package equidistant control device provided by the invention can adjust the pressure values of the anti-package rods effectively, so that the pressure values on two sides of the green tire tend to be same, so that synchronous movement of the anti-package rods on two sides is ensured, the stress on two sides of the green tire is same, and the quality of the green tire is improved.

Description

technical field [0001] The invention relates to the technical field of tire processing equipment, in particular to a mechanical building drum, turn-up isometric control device and a control method thereof. Background technique [0002] In the turn-up stage of tire forming, the mechanical building drum needs the turn-up rod to support the rubber material like an umbrella, so that the rubber material such as the inner liner and the cord can wrap the bead and form it into the required shape of the raw tire. [0003] At present, the movement of the turn-up rod is powered by the motor, which is boosted to drive the movement, and the turn-up rod moves along the inclined plane on the forming drum. The movement position of the turnup rod is judged by the formed raw tire, and the parameters of the servo motor are adjusted. [0004] However, both sides of the mechanical forming drum are provided with a turn-up rod device and a driving device, and the driving device controls the opera...

AI Technical Summary

Problems solved by technology

Since the turn-up rods on the turn-up rod devices on both sides of the mechanical forming drum are controlled by a separate driving device, it is inevitable that the pressure on both sides of the mechanical forming drum is different. In this case, the pressure on both sides of the green tire The pressing state of the turnup rod is unstable, and the deviation of the pressure on both sides makes the quality of the raw tire unstable
