Description

Technical Field

[0001] This utility model relates to the field of tire production equipment, and more specifically to a tire tread exhaust line device. Background Technology

[0002] As is well known, during the tire manufacturing process, air may accumulate between tire layers due to factors such as tread material, tire profile, and manufacturing process. If this air is not expelled in time, it will form air bubbles or cavities inside the tire, seriously affecting the tire's quality and service life. Summary of the Invention

[0003] To overcome the shortcomings of the existing technology, this utility model provides a tread venting device that can press specific venting grooves into the tire tread to provide a venting channel for air accumulated between layers, ensuring that the gas inside the tire can be smoothly discharged, thereby improving the tire's quality and service life.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a tire tread exhaust line device, which is provided with a conveying roller. The feature is that an exhaust roller is installed between two parallel conveying rollers, and a pressure roller is installed parallel above the exhaust roller. Several convex ribs with the same structure and size are evenly distributed in the circumferential direction of the exhaust roller. The convex ribs are horizontal with the axial direction of the exhaust roller and have the same length in the extension direction.

[0005] The conveying roller and the exhaust roller have the same diameter.

[0006] The uppermost sides of the exhaust roller and the conveyor roller are on the same horizontal plane.

[0007] The beneficial effects of this invention are that by adding venting lines to the tread, the gas between layers is ensured to be smoothly discharged during the molding and pressing process, achieving a uniform and effective venting effect. By venting the accumulated gas between layers, air bubbles or cavities are avoided inside the tire, thereby improving tire quality and service life. At the same time, the device has a simple structure, is easy to implement, and is convenient to operate, making it suitable for various tire manufacturing production lines.

[0013] In the figure, the present invention includes a conveying roller 3, an exhaust roller 4 installed between two parallel conveying rollers 3, and a pressure roller 2 installed parallel above the exhaust roller 4. Several convex ribs 5 of the same structure and size are evenly distributed around the circumference of the exhaust roller 4. The convex ribs 5 are axially horizontal with the exhaust roller 4 and have the same length in the extension direction. The uppermost sides of the exhaust roller 4 and the conveying roller 3 are on the same horizontal plane. The conveying roller 3 and the exhaust roller 4 are on the same side and have the same diameter. The convex ribs 5 and the exhaust roller 4 are both made of rigid material and are designed as a single piece, ensuring the stability and durability of the convex ribs 5. The convex ribs 5 are evenly distributed around the circumference of the exhaust roller 4, ensuring the uniformity of the exhaust line. The axial horizontal of the convex ribs 5 and the length in the extension direction are consistent with the exhaust roller, ensuring the continuity and consistency of the exhaust line.

[0014] The conveyor roller 3 carries and drives the tread 1. The exhaust roller 4 has raised ridges 5 on its surface, which are used to press exhaust grooves 6 into the tread 1. The pressure roller 2 is located directly above the exhaust roller 4 and is used to apply pressure to the tread 1 so that it fits tightly against the exhaust roller 4. During production, the tread 1 is placed on the conveyor roller 3 and carried and driven by the conveyor roller 3. When the tread 1 passes the pressure roller 2, it is subjected to pressure and fits tightly against the exhaust roller 4. The raised ridges 5 on the surface of the exhaust roller 4 press out transverse exhaust grooves 6 of equal distance and depth on the lower surface of the tread 1.
