Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of exhaust line extrusion, in particular to an exhaust line extrusion device. Background Art
[0002] Pressing vent lines on the tread and other semi-components can effectively prevent the phenomenon of air pockets, delamination and delamination in the finished tire. The vent line pressing process requires that the vent lines be arranged equidistantly, run through the entire surface of the tread and other semi-components, and have clear indentations that meet the depth requirements and are consistent in depth. Such indentations can play a good role as vent channels in the subsequent rolling venting process of the molding process.
[0003] At present, the exhaust line device adopts a self-weighted tread roll. The exhaust line device includes a frame spanning above the linkage line, a lifting cylinder arranged on the top of the frame, and a tread roll bracket connected to the cylinder piston. The bracket is equipped with a tread roll with a rotatable outer ring. Taking the tread component as an example, during use, the lifting cylinder controls the lifting of the tread roll, so that the tread roll is close to the tread on the linkage line to be pressed. When the exhaust line is reached, the multiple stick pieces on the tread roll sleeved on the central axis are pressed on the tread surface in accordance with the tread contour. The weight of the stick piece itself is used to make the corresponding edge stick installed under the tread produce an exhaust line indentation on the lower surface of the tread. The self-weighted tread roll has the same pressing force on the stick piece of unit width of the cross section, but the thickness of the tread cross section is different. The same pressing force cannot adapt to the change of thickness, resulting in deep indentation in thin parts and shallow or even no indentation in thick parts. This phenomenon is more obvious in the shoulder and wing rubber parts, resulting in inconsistent depth of the extruded tread exhaust line, and disconnection and discontinuity of the exhaust line in some parts, which cannot meet the process requirements.
[0004] Moreover, when the exhaust line is pressed, the temperature of the extruded semi-component has not cooled down, and the temperature is about 110℃, and there is smoke rising. In the smoke environment, the smoke will slowly condense on the stick pieces, and the stick pieces will condense with each other, affecting the movement of a single piece. The rotation of the outer ring of the thousand-layer piece will also be hindered and cannot rotate flexibly. At this time, the rubber is soft and sticky, and the rubber will also adhere to the stick pieces, affecting the rotation of the outer ring of the thousand-layer piece.
[0005] Based on this, an exhaust line extrusion device is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content
