Description

Technical Field

[0001] The invention relates to the technical field of cord winders, and in particular to a steel cord winder. Background Art

[0002] Pneumatic tires are mainly composed of rubber parts and cord layers. The outer surface of the tire is all rubber, but the rubber only plays a role in cushioning, puncture resistance, and wear resistance in the tire carcass. The cord hidden in the rubber is the real "worker". The cord is also called cord fabric or cord line. It is a fabric with thicker warp and denser weaving, and thinner weft and sparser weaving. The cord is used as a skeleton material in the tire and is the main force-bearing component of the tire.

[0003] Usually, in the production process, each layer of tire cord is a combination of rubber + steel cord + rubber. The steel cord and rubber are vulcanized to improve the tire's load-bearing capacity and wear resistance. As a steel cord manufacturer, in order to understand whether the various indicators of steel cords of different specifications produced by it meet the standard requirements after rubber calendering and vulcanization, and then guide the adjustment of the steel cord production process, it is necessary to configure a cord extruder for testing. However, the cord extruders used for testing on the market are not equipped with corresponding wire take-up machines. The cords after steel wire and rubber calendering need to be manually collected, which is inconvenient to operate. Except for the middle section for sampling and testing, a large section of cords needs to be scrapped at the beginning and end. Because there is no cord collection device, the on-site operating environment is untidy and the discarded cords are placed everywhere, causing waste. Summary of the invention

[0004] The purpose of the present invention is to provide a steel cord winder to solve the problems in the prior art, so as to facilitate the automatic collection of the cord after vulcanization calendering and extrusion, and to facilitate packaging after collection, thereby preventing the chaotic environment on site.
