Detachable silicone rubber ring device of engineering radial tire one-step forming machine

Abstract

The utility model relates to a detachable silicone rubber ring device of an engineering radial tire one-step forming machine, and belongs to the field of tire production equipment. And the left end of the triple sleeve is hermetically connected with the left turn-up capsule through a left silicon rubber ring, and the right end of the triple sleeve is hermetically connected with the right turn-up capsule through a right silicon rubber ring. The forming drum bead ring supporting block has the advantages that the silicone rubber ring is tightly bound at the position of the forming drum bead ring supporting block, a seam allowance portion is in contact with the silicone rubber ring during production, and the situation that a capsule adheres to the seam allowance portion is avoided.

Description

Technical Field

[0001] The utility model relates to the field of tire processing equipment, in particular to a detachable silicone rubber ring device of a one-step molding machine for an engineering radial tire. Background Art

[0002] As we all know, in the one-step molding production of engineering radial tires, the tire blank needs to be produced in conjunction with the bladder, and is produced by reverse packaging and pressing. In the existing engineering radial tire manufacturing process, when the one-step molding machine produces 16.00R25TL569A and other airtight layer bag mouth forms, the capsule mouth is stuck with capsule fluff, which affects the fluidity of the vulcanized rubber and easily causes glue shortage; at the same time, the molded tire mouth is seriously stuck with the capsule, and the tire cannot be unloaded normally. Manual operation is required for tire unloading, which easily causes damage to the mouth, damages the bladder and seriously affects production efficiency. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a detachable silicone rubber ring device for an engineering radial tire one-step molding machine, which eliminates the problem of bladder sticking at the mouth of the tire blank and ensures normal production efficiency and product quality.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a detachable engineering radial tire one-step forming machine silicone rubber ring device, which is provided with a triple sleeve, and is characterized in that the left end of the triple sleeve is sealed and connected with the left reversed capsule through the left silicone rubber ring, and the right end of the triple sleeve is sealed and connected with the right reversed capsule through the right silicone rubber ring.

[0005] The utility model has the beneficial effect that the silicone rubber ring is tightly bound at the position of the steel wire ring support block of the forming drum, and during production, the sub-mouth part contacts with the silicone rubber ring, thereby avoiding the situation that the sub-mouth part is adhered to the capsule. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0007] Figure 1 A schematic structural diagram of the utility model.

[0008] In the figure, 1. left reverse capsule, 2. triple sleeve, 3. left silicone rubber ring, 4. right reverse capsule, 5. right silicone rubber ring. DETAILED DESCRIPTION

[0009] In the figure, the utility model is provided with a triple sleeve 2, the left end of the triple sleeve 2 is sealed connected to the left reverse capsule 1 through the left silicone rubber ring 3, and the right end of the triple sleeve 2 is sealed connected to the right reverse capsule 4 through the right silicone rubber ring 5.

[0010] A set of detachable silicone rubber ring devices is added to the main forming drum, which is tightly bound to the position of the steel wire ring support block of the forming drum. During production, the mouth of the sub-piece is in contact with the silicone rubber ring, which avoids the situation where the capsule sticks to the mouth of the sub-piece; the silicone rubber ring is tightly bound to the position of the steel wire ring support block of the forming drum, which increases the wear resistance of the capsule; the mouth of the sub-piece is in contact with the silicone rubber ring, which reduces the generation of capsule fluff and reduces the rework rate of the mouth of the sub-piece due to lack of glue; due to the high elasticity of the silicone rubber ring, it can expand synchronously with the inflation of the capsule, ensuring that the position of the forming support block does not shift and ensuring the stability of the process parameters.

Claims

1. A detachable silicone rubber ring device for a one-step building machine for engineering radial tires, provided with a triple sleeve, characterized in that: The left end of the triple sleeve is sealed and connected to the left reverse capsule via a left silicone rubber ring, and the right end of the triple sleeve is sealed and connected to the right reverse capsule via a right silicone rubber ring.
