Description

TECHNICAL FIELD

[0001] The present application relates to the field of tire blank production, in particular to a tire blank automatic marking device based on a winding machine device. BACKGROUND

[0002] In the field of tire manufacturing technology, the degree of automation and precision of tire production is constantly improving, which is of great significance to improve production efficiency and ensure product quality. Especially in the production of engineering tires, the application of equipment such as the winding machine of radial tires makes the production process more efficient. For example, a double-head synchronous radial tire winding machine disclosed in Chinese patent No. CN119239021B can simultaneously press the rubber strip on the rotating tire blank through the cooperation of the X-axis drive assembly, Y-axis drive assembly and rotary drive assembly on the two winding mechanisms.

[0003] In the tire blank production process, the center line and other markings provide an important basis for subsequent detection or process reference standard positioning, and their accuracy directly affects the quality and performance of the tire. In the conventional process of tire blank production in tire manufacturers, in order to mark the center line and other markings, the method commonly used is to mark the laser marking under the light cursor column, and then manually hold the marking paint pot close to the rotating tire blank according to the laser marking. There are corresponding marking paint pots suitable for manual holding available on the market. In addition, during the entire tire production process, the positioning of the markings mainly relies on the manual operation of the workers and the reference of the laser markings, and lacks more automated and accurate positioning means.

[0004] However, the existing technology of manually holding the marking paint pot according to the laser marking has obvious defects. Since this process is operated by hand, the workers' operation proficiency varies, and the laser marking itself also has deviations. This series of factors leads to the accumulation of deviations, which in turn causes the deviations of the subsequent detection or reference standards, and cannot meet the requirements of high-precision markings for tire production.
