CN-114654782-B - Method for preventing left and right movement of glue component during lamination

Abstract

The invention relates to a method for preventing left and right movement of a rubber component in a pressing manner, and belongs to the field of tire production. The two ends of the cylindrical middle telescopic mechanism are respectively fixed with a cylindrical left capsule drum and a cylindrical right capsule drum, the axes of the middle telescopic mechanism and the left capsule drum and the right capsule drum are overlapped, two sharp compression rollers are arranged behind the middle telescopic mechanism, the glue parts are attached to the left capsule drum, the right capsule drum and the middle telescopic mechanism, the sharp compression rollers are in a pressing waiting position, an inflation control system controls the left capsule drum and the right capsule drum to inflate, the glue parts are inflated at the positions where the left capsule drum and the right capsule drum are contacted, the surfaces of the left capsule drum and the right capsule drum after inflation form two conical surfaces inclining inwards, at the moment, the two sharp compression rollers roll the glue parts from the middle to the two sides respectively, so that the glue parts are prevented from being stringed left and right when rolling, and after pressing, the inflation control system controls the left capsule drum and the right capsule drum to deflate immediately, and the glue parts and the sharp compression rollers return to the initial positions.

1. 1. A method for preventing the left and right sides of a rubber component from moving in a pressing mode includes such steps as fixing cylindrical left and right rubber drums at two ends of said central telescopic mechanism, overlapping the axes of said left and right rubber drums, installing two pointed press rollers behind said central telescopic mechanism, attaching the rubber component to left, right and middle telescopic mechanisms, pressing the pointed press rollers on the left and right rubber drums, inflating the left and right rubber drums by an inflating control system, expanding the rubber component at the contact position between them, and forming a conical surface between them.

Description

Method for preventing left and right movement of glue component during lamination Technical Field The invention belongs to the field of tire production, and in particular relates to a method for preventing left and right movement of a rubber component in a pressing manner. Background As is well known, in the production of a tire building process, after a rubber part is attached to the surface of a capsule drum, a manual hand-held pressing roller is adopted to press the rubber part in a rotary drum mode, and gas in the rubber part is discharged. Disclosure of Invention In order to overcome the defects of the prior art, the invention provides a method for preventing the left and right movement of the glue parts in the pressing manner, which improves the production efficiency and the pressing quality, ensures the positioning precision of the glue parts, prevents the left and right movement of the glue parts and reduces the labor intensity. The technical scheme includes that the method for preventing left and right movement of the glue component in a pressing mode is characterized in that two ends of a cylindrical middle telescopic mechanism are respectively fixed with a cylindrical left capsule drum and a cylindrical right capsule drum, the middle telescopic mechanism coincides with axes of the left capsule drum and the right capsule drum, two sharp compression rollers are arranged behind the middle telescopic mechanism, the glue component is attached to the left capsule drum, the right capsule drum and the middle telescopic mechanism, the sharp compression rollers wait for pressing in a pressing waiting position, an inflation control system controls the left capsule drum and the right capsule drum to inflate at positions where the glue component is contacted with the left capsule drum and the right capsule drum to expand, two conical surfaces which incline inwards are formed on the surfaces of the left capsule drum and the right capsule drum after inflation, one conical surface is formed between the left capsule drum and the right capsule drum and the glue component, the two sharp compression rollers roll the glue component from the middle to two sides respectively, therefore the glue component is prevented from moving in a pressing mode, after pressing is finished, the left capsule drum, the right capsule drum and the right capsule drum are controlled by the inflation control system, the glue component is prevented from being stretched to be deformed by the sharp compression rollers immediately after pressing is finished. The automatic pressing device has the beneficial effects of being convenient to operate, preventing the rubber component from moving left and right after being pressed on the drum, effectively removing bubbles in the rubber component, ensuring the positioning precision of the rubber component, and improving the equipment efficiency and reducing the labor intensity of personnel by replacing manual pressing with automatic pressing. Drawings The invention will be further described with reference to the drawings and examples. Fig. 1 is a schematic structural view of the present invention. Fig. 2 is a schematic view of the present invention when the glue part is pressed. In the figure, a left capsule drum, a middle telescopic mechanism, a sharp press roller, an inflation control system, a glue component and a right capsule drum are respectively arranged at the left and the right sides of the capsule drum. Detailed Description In the figure, the invention is provided with a middle telescopic mechanism 2, two ends of the cylindrical middle telescopic mechanism 2 are respectively fixed with a cylindrical left capsule drum 1 and a cylindrical right capsule drum 6, the axes of the middle telescopic mechanism 2, the left capsule drum 1 and the right capsule drum 6 are overlapped, two sharp compression rollers 3 are arranged at the rear of the middle telescopic mechanism 2, the contact area between the compression rollers and the surfaces of the glue parts is reduced by adopting the sharp compression rollers during rolling, and bubbles among the glue parts can be effectively removed. Before starting the press-fit (see fig. 1), the glue component 5 is attached to the left capsule drum 1, the right capsule drum 6 and the middle telescopic mechanism 2, and the sharp press roller 3 waits for press-fit at a press-fit waiting position. When the pressing starts (see fig. 2), the inflation control system 4 controls the left capsule drum 1 and the right capsule drum 6 to pre-inflate, the positions where the glue parts 5 are contacted with the left capsule drum 1 and the right capsule drum 6 expand, at this time, a conical surface is formed between the left capsule drum 1 and the right capsule drum 6 and the glue parts 5, the surfaces of the left capsule drum 1 and the right capsule drum 6 after inflation form two conical surfaces inclining inwards, the friction force between the surfaces of the left capsule dru
