Apex strip bundling device

Abstract

The patent relates to the field of tire manufacturing technological equipment and discloses an apex strip bundling device. The apex strip bundling device is characterized in that support rods in circumferential distribution and bearing platforms are used for placing an apex strip bundle, and the bearing platforms horizontally jack up the apex strip bundle. A spiral rack is rotated to wrap the apex strip bundle in the spiral rack. As the spiral rack is flexible, the spiral rack can be bent and deformed in the length direction while the diameter of the spiral rack is kept unchanged, and after the apex strip bundle is placed in the spiral rack, the spiral rack is circular-ring-shaped. A motor is started to drive a driving roller to rotate; and as the driving roller is propped against the spiral rack, the driving roller drives a bundling head to perform spiral movement along the spiral rack, accordingly, the bundling head continually moves from the outer side of the apex strip bundle to the inner side and then moves from the inner side of the apex strip bundle to the outer side, and further, a packing strap on a packing strap roller is spirally wound on the apex strip bundle to finish bundling of the apex strip bundle. The patent aims to achieve the purpose of bundling the annular apex strip bundle.

Description

technical field [0001] The invention relates to the field of tire production process equipment. Background technique [0002] The main function of the bead in the tire is to firmly fix the tire on the rim, overcome the stress generated by internal pressure, the centrifugal force generated at high speed, etc., and ensure the normal driving of the car. The bead is usually composed of steel wire ring, apex, chafer and so on. The apex acts as a filler in the bead, if there is no apex, it may form a dead angle in the bead. The production of apex strips is produced by an extruder. After the rubber raw material is added to the extruder, the extruder continuously extrudes thin strips of apex strips through a molding die. The continuous production of the extruder makes the length of the extruded apex very long, and it is usually necessary to coil the apex into a ring and pack it in bundles for easy transportation. [0003] For the bundling and packaging of ring objects, ring body ...

AI Technical Summary

Problems solved by technology

However, when using the ring body winding machine to bundle the apex strips, since the cross section of the apex strips that has been coiled into a ring is composed of multiple strands of apex strips, the rotating roller cannot drive the apex strips to rotate as a whole. Therefore, The existing ring body winding machine cannot pack the apex strips whose cross-section is composed of multiple strands of thin apex strips.
