Problems solved by technology

[0003] In the Chinese patent with the authorized announcement number CN101966756B, a fully automatic tread lamination machine and its lamination method are provided, which mainly solves the problem that there is a certain error between the tread rubber after cutting and the circumference of the carcass surface, which often leads to If the tread rubber is not long enough or there is an excess head, it can effectively save the tread rubber material, control the longitudinal centering and coaxiality between the tread rubber and the carcass, avoid deviation, and make the lamination operation accurate High resistance, strong tightness, not easy to leave air bubbles
[0004] At present, the existing bonding roller moves along the axis of the auxiliary drum from one side of the tread rubber to the other side to roll and bond the tread rubber in the overlapping area, but the stroke of the bonding roller is limited, so there is no It is suitable for the preparation of wide-tread tires; moreover, the rolling direction of the pressure roller in the prior art is perpendicular to the arc direction of the tread overlapping area, which is not conducive to the exhaust at the overlapping area, causing the tire to be easily damaged at the overlapping area. Affect tire quality

Abstract

The invention relates to a tire tread laminating machine and a laminating method thereof, and belongs to the technical field of tire tread forming. An auxiliary drum component comprises an auxiliary drum and a movement mechanism for driving the auxiliary drum to move; and a compression roller component comprises a compression roller, a large air cylinder driving the compression roller to move in the vertical direction, a small air cylinder driving the compression roller to move in the horizontal direction and a fine adjustment assembly. An air exhaust hole penetrating through the upper wall ofa cover body is formed in the upper portion of the cover body, the lower ends of the two side walls, perpendicular to the axis direction of the compression roller installed in the cover body, of thecover body are in a curved surface shape, and sealing rubber strips are installed at the lower ends of the four side walls of the cover body. By the adoption of the laminating machine, the running mode and the acting direction of the compression roller are changed, the length of the compression roller is increased, tread laminating is conducted in an air exhaust mode, and the tread lap joint quality can be improved.

Description

technical field [0001] The invention relates to the technical field of tire tread molding, in particular to a tire tread bonding machine and a bonding method thereof. Background technique [0002] When the vehicle is running, the tire running surface that is in contact with the ground is the tire tread. In the tire production process, on the auxiliary building drum, one or more layers of belt layers are firstly pasted, and then the cut and fixed-length tread rubber is pasted on the belt layer. Two parts of the tread rubber The ends need to be lapped and pressed tightly; the tread formed into a ring is then moved to the main building drum for overall tire building. In order to ensure the bonding effect of the overlapping parts, the end of the tread is generally cut out with a slope to maintain a certain width of the overlap, and the slope is overlapped. [0003] In the Chinese patent with the authorized announcement number CN101966756B, a fully automatic tread lamination ma...
