Description

Technical Field

[0001] The present application belongs to the technical field of tire production equipment, and more specifically, relates to a tread straight puncture hole device. Background Art

[0002] The tread of a tire is formed by pressing at least two layers of rubber products. Bubbles are easily generated between the rubber products of the tread, and the existence of such bubbles has a great impact on the quality of the tire. Therefore, the tread needs to be punctured after pressing to facilitate the discharge of gas between the rubber products.

[0003] The existing tread puncture has the following main disadvantages: it is completed by manual acupuncture, and its efficiency is very low; with the advancement of technology, some manufacturers have also developed mechanical automatic or semi-automatic puncturing devices, which are all independent of the tread production line and cannot perform online puncturing on the tread production line, which is still not conducive to improving production efficiency.
