Methods to prevent left and right movement when pressing adhesive parts

Abstract

This invention relates to a method for preventing lateral movement of rubber components during pressing, belonging to the field of tire manufacturing. A cylindrical telescopic mechanism has cylindrical left and right bladder drums fixed at both ends. The axis of the telescopic mechanism coincides with that of the left and right bladder drums. Two pointed pressure rollers are installed behind the telescopic mechanism. The rubber component is attached to the left and right bladder drums and the telescopic mechanism. With the pointed pressure rollers in the pressing waiting position, the inflation control system controls the left and right bladder drums to inflate. The contact points between the rubber component and the left and right bladder drums expand, forming two inwardly inclined conical surfaces on the inflated surfaces of the left and right bladder drums. At this time, the two pointed pressure rollers press the rubber component from the center outwards, ensuring that the rubber component does not move laterally during pressing. After pressing, the inflation control system immediately deflates the left and right bladder drums, and the left and right bladder drums, rubber component, and pointed pressure rollers return to their initial positions.

Description

Technical Field

[0001] This invention belongs to the field of tire manufacturing, and more specifically, it is a method for preventing left-right movement of rubber components during pressing. Background Technology

[0002] As is well known, in the tire forming process, after the rubber components are attached to the surface of the bladder drum, the rubber components are currently pressed manually using a hand-held roller in conjunction with a rotating drum to expel the gas from the rubber components. This method is not only inefficient, but also prone to causing the rubber components to move left and right on the drum during the pressing process due to the uneven surface and inconsistent diameter of the drum below the rubber components. This affects the positioning accuracy of the rubber components. The entire pressing process requires manual pressing and handling, which is labor-intensive and results in unsatisfactory pressing results. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a method for preventing left-right movement of adhesive components during pressing, thereby improving production efficiency and pressing quality, ensuring the positioning accuracy of adhesive components, preventing left-right movement of adhesive components, and reducing labor intensity.

[0004] The technical solution adopted by this invention to solve its technical problem is: a method for preventing left-right movement during the pressing of adhesive components, comprising a central telescopic mechanism, characterized in that cylindrical left and right capsule drums are respectively fixed at both ends of the central telescopic mechanism, the central telescopic mechanism is aligned with the axes of the left and right capsule drums, and two pointed pressure rollers are installed at the rear of the central telescopic mechanism; the adhesive component is adhered to the left and right capsule drums and the central telescopic mechanism, the pointed pressure rollers wait for pressing in the pressing position, and the inflation control system controls the left and right capsule drums. During inflation, the rubber component expands at the contact points with the left and right capsule drums, forming two inwardly inclined conical surfaces on the surfaces of the inflated left and right capsule drums. A conical surface is also formed between the left and right capsule drums and the rubber component. At this time, two pointed pressure rollers press the rubber component from the middle to both sides to ensure that the rubber component does not move from side to side during pressing. After pressing, the inflation control system controls the left and right capsule drums to deflate immediately, and the left and right capsule drums, the rubber component, and the pointed pressure rollers return to their initial positions to prevent the rubber component from being stretched and deformed.

[0005] The advantages of this invention are that it is easy to operate, prevents the adhesive components from moving left and right after being pressed on the drum, effectively eliminates air bubbles inside the adhesive components while ensuring the positioning accuracy of the adhesive components, and automatically presses instead of manually presses, thereby improving equipment efficiency and reducing the labor intensity of personnel.

[0006] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0007] Figure 1 This is a schematic diagram of the structure of the present invention.

[0008] Figure 2 This is a schematic diagram of the process of pressing the adhesive components according to the present invention.

[0010] In the figure, the present invention is provided with an intermediate telescopic mechanism 2. The cylindrical intermediate telescopic mechanism 2 has a cylindrical left capsule drum 1 and a right capsule drum 6 fixed at both ends. The axis of the intermediate telescopic mechanism 2 coincides with that of the left capsule drum 1 and the right capsule drum 6. Two pointed pressure rollers 3 are installed behind the intermediate telescopic mechanism 2. The pointed pressure rollers reduce the contact area between the pressure roller and the surface of the glue component during rolling, which can effectively remove air bubbles between the glue components.

[0011] Before starting the pressing process (see attached) Figure 1 The adhesive component 5 is attached to the left capsule drum 1, the right capsule drum 6, and the intermediate telescopic mechanism 2, while the pointed pressure roller 3 waits in the pressing waiting position for pressing. When pressing begins (see attached...), Figure 2 The inflation control system 4 controls the left capsule drum 1 and the right capsule drum 6 to pre-inflate. The rubber component 5 expands at the contact points with the left and right capsule drums 1 and 6, forming a conical surface between them. Furthermore, the inflated surfaces of the left and right capsule drums 1 and 6 form two inwardly inclined conical surfaces. Pre-inflation of the left and right capsule drums 1 and 6 increases the friction between their surfaces and the rubber component 5. At this time, the two pointed pressure rollers 3 press the rubber component 5 from the center outwards. This pre-inflation method ensures that the rubber component 5 does not move laterally during pressing. After pressing (see appendix)... Figure 1 The left capsule drum 1, right capsule drum 6, rubber component 5, and pointed pressure roller 3 return to their initial positions, and the pressing is completed. The inflation of the left capsule drum 1 and right capsule drum 6, the pressing of the rubber component 5, and the deflation of the left capsule drum 1 and right capsule drum 6 are controlled by the inflation control system 4 to ensure that the left capsule drum 1 and right capsule drum 6 deflate immediately after the pressing of the rubber component 5 is completed, to prevent the rubber component 5 from being stretched and deformed.
