Description

Improved turn-up bladder for producing run-flat tire

Technical Field

The utility model relates to a run-flat tire technical field, concretely relates to turn-up capsule of production run-flat tire of improvement.

Background

Compared with the common tire, the run-flat tire is additionally provided with the supporting rubber for ensuring the running stability of the tire when the tire is damaged and deflated, thereby ensuring the safety of passengers. In the production of semi-steel run-flat tire, need set up the recess on the building drum and be used for laminating support rubber, this has led to inside lining sizing material and building drum's area of contact to reduce, and the inside lining has after cutting and cuts the walking angle, generally 5-10 degrees angles, and material tip reaches the capsule surface earlier when laminating on the drum, and the inside lining sizing material will appear if the tip can not bond on the capsule surface and fall the problem of material, influences the production efficiency and the production quality of tire.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model aims at providing a production run-flat tire's of improvement turn-up bladder, it can make the inside lining sizing material not fall the material when laminating, and turn-up bladder shrink can not lead to the inside lining sizing material to contract together to improve the production efficiency and the yields of tire child base.

The specific technical scheme is as follows:

the utility model provides a turn over and wrap capsule of production run-flat tire of improvement, turn over and wrap the capsule and include capsule main part, elasticity cloth and air cock, the cladding has one deck elasticity cloth on the surface of capsule main part, the hole has been seted up on the elasticity cloth, be provided with the air cock in the capsule main part.

Preferably, the holes are uniformly arranged on the elastic cloth along the circumference, and the holes are close to one side edge of the elastic cloth.

Preferably, the air nozzles are uniformly arranged on the capsule body along the circumference.

Preferably, glue is smeared at the round holes.

The utility model has the advantages that:

when producing the semi-steel run-flat tire, evenly distributed has a plurality of apertures on the anti-sticking cloth of the outer surface of the left and right sides turn-up bladder, make the inside lining sizing material contact with the turn-up bladder of rubber material, suitably improve the cohesive force of inside lining sizing material and turn-up bladder, guarantee when laminating inside lining sizing material, both can not produce because of the area of contact of shaping drum and inside lining sizing material reduces and fall the material, also can not contract with the sizing material when turning-up bladder contracts together, thereby reduce the frequency of manual intervention, improve the production efficiency and the yields of tire blank greatly.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 in conjunction with fig. 2: an improved turn-up bladder for producing run-flat tire, the turn-up bladder 40 includes a bladder body 41 with a hollow interior for inflation and deflation, an elastic cloth 42 and air nozzles 43, the outer surface of the bladder body 41 is covered with a layer of elastic cloth 42, the elastic cloth 42 is provided with a plurality of holes 421, and the bladder body 41 is provided with a plurality of air nozzles 43.

Furthermore, the holes 421 are uniformly arranged on the elastic cloth 42 along the circumference, and the holes 421 are close to one side edge of the elastic cloth 42; this arrangement facilitates the holes 421 to be in sufficient contact with the lining compound 50 when the compound is applied.

Further, the air nozzles 43 are uniformly provided on the capsule body 41 along the circumference.

Further, glue is coated on the holes 421; this arrangement can enhance the adhesion between the capsule body 41 and the lining rubber 50.

The working principle is as follows: during the use, install both ends about forming drum 10 respectively with left capsule drum 20 and right capsule drum 30, install respectively on left capsule drum 20 and right capsule drum 30 with turning up capsule 40 (need to ensure when turning up capsule 40 installs that one side that is provided with hole 421 is towards forming drum 10, in order to ensure during the rubberizing, inside lining sizing material 50 can contact with hole 421), follow closely around 10 circumference laminating inside lining sizing material 50, the surface of turning up capsule 40 should be with forming drum 10 drum face parallel and level (as shown in fig. 3) when laminating inside lining sizing material 50, inside lining sizing material 50 laminating back, the side that has hole 421 on the turning up capsule 40 outer wall is embedded into inside lining sizing material 50, capsule body 41 sees through hole 421 and inside lining sizing material 50 bonds mutually.

The elastic cloth 42 on the outer surface of the reverse-wrapping capsule 40 is used for preventing the lining rubber material 50 from being bonded with the reverse-wrapping capsule 40, so that the problem of folding caused by the fact that the lining rubber material 50 shrinks along with the reverse-wrapping capsule 40 shrinks when the reverse-wrapping capsule 40 shrinks is avoided; the rubber material of the capsule main body 41 can be leaked out through the arrangement of the holes 421 on the elastic cloth 42, the rubber material of the capsule main body 41 and the lining rubber material 50 have good cohesiveness, the cohesiveness between the turn-up capsule 40 and the lining rubber material 50 can be adjusted to a proper range by changing the arrangement mode and the diameter of the holes 421, the lining rubber material 50 can be prevented from falling due to the fact that the contact area of the lining rubber material 50 and the drum surface of the forming drum 10 is small, and the fact that the rubber material cannot shrink when the turn-up capsule 40 shrinks can be guaranteed.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
