Description

Technical Field

[0002] In modern industrial production, tires are an important part of vehicles, and their quality and performance are directly related to the driving safety and comfort of vehicles. With the continuous development of the automobile industry, the requirements for tires are also increasing. In the traditional tire production process, the gluing process often relies on manual operation, which is not only inefficient, but also difficult to ensure the uniformity of the gluing. Manual gluing is also easily affected by factors such as the operator's technical level and working status, resulting in unstable gluing quality. At the same time, manual gluing is labor-intensive and costly, and it is difficult to meet the needs of large-scale production. In order to solve these problems, tire gluing machines came into being. Tire gluing machines can achieve accurate and efficient gluing operations through automated technical means. It can accurately control the thickness and uniformity of the glue coating and improve the quality and performance of the tire. In addition, the glue coating machine can also improve production efficiency, reduce production costs, and bring significant economic benefits to tire manufacturers. For example, announcement number CN108144776B discloses a tire glue coating machine, including a glue coating device for coating the inner wall of the tire with glue and a tire unloading device for transporting the glued tire from the glue coating device. The glue coating device includes a support roller for driving the tire, a spray gun arranged above the support roller and capable of extending into the inner ring of the tire, and also includes a movable limiting roller arranged on one side of the support roller. The tire unloading device includes a driving device that drives the movable limiting roller to extend forward to resist the side end face of the tire or retract backward to allow the tire to pass, a tire unloading roller supported by the support roller, and a tire rotating device capable of moving back and forth between the support roller and the tire unloading roller. The tire transfer mechanism is provided with a blocking roller which abuts against the end face of one side of the tire relative to the tire unloading roller. Compared with the traditional tire glue coating machine, the tire transfer mechanism can automatically recycle the tire after gluing, thereby improving production efficiency. The glue coating machine in the prior art can meet the needs of use, but when in use, the extension spacing required is different due to the different sizes of tires, and this device cannot adjust the spacing, resulting in uneven glue coating, thereby affecting product quality. At the same time, this device cannot limit the tire during the gluing process. The movement of the tire will cause the glue coating thickness to be uneven, thereby failing to produce the expected effect. The device needs to position the tire before gluing, which is not only inefficient but also has certain safety hazards. Summary of the invention
