Description

Tire forming machine tread feeding frame with automatic length compensation function

Technical Field

The utility model relates to a rubber tire processing machinery technical field specifically is an automatic length compensation's tire building machine tread feed frame.

Background

At present, a tire building machine is mainly applied to a tire tread in two modes, wherein one mode is a pre-cutting mode. In the former process, the tread is cut according to the process length, placed on a shutter vehicle or a box vehicle and conveyed to the side of a tire forming machine, and then manually moved to a tread feeding frame to attach the pre-cut tread to an attaching drum in the forming process. Because mass production reason, it is longer to lead to the good tread of prejudging to place on tripe car or boxcar, and the sizing material contracts, causes the length to shorten, when laminating on the laminating drum, can not laminate a week completely, needs artifical manual extension to required length, and this kind of artifical laminating of lengthening can lead to tread thickness overall length direction thickness inequality, and this is the leading cause that leads to the unqualified dynamic balance of tire.

The other mode is an online cutting mode of rolling and feeding. The tire tread is rolled and stored in the previous process, and when the tire tread is molded, the tire tread is cut and attached to an attaching drum after being guided away and a tire tread feeding frame is fixed in length on line. In this on-line cutting method, although the cutting length is stable, since the upper surface must be stretched due to a problem in the tread thickness during the application, it is also difficult to ensure the application effect of the wound tread using this device.

At present, the method for measuring the length of the tread is to detect the distance between the head and the tail through a photoelectric detection switch, and then calculate the theoretical length of the tread through calculation. Because the tread is of various types and the thickness and the cutting angle of the tread are different, the calculated data have errors, the length of the tread is still deviated, the measurement is inaccurate, and the tread lengthening accuracy cannot be realized.

Because the tread section is similar to the trapezium, the prior tread stretching compression roller can only press the upper side of the trapezium, and the two inclined sides can not press, which can lead to incomplete stretching. When the tread is laminated on the drum, the laminating compression roller adopts single laminating compression roller more, because the tread section is approximately trapezoidal, single laminating compression roller leads to the tread laminating drum to the drum on, the laminating effect is not good, unable inseparable combination.

At present, the tire tread is attached to the drum, automatic joint cannot be achieved, manual auxiliary joint is needed, labor intensity is increased, and forming time is prolonged. The tread conveying feeding frame forwards sends the action, adopts the cylinder mode, and the cylinder impact force can cause the damage accident of multiple equipment stop device.
