Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.

The present invention will be further described with reference to the accompanying drawings and preferred embodiments.

Example (b):

as shown in fig. 1, for the basic structure of the preferred embodiment of the present invention, a tire inner liner provided with sub-opening glue, including an airtight layer 2 for preventing tire leakage, a transition layer 1 laminated with the airtight layer 2, and two first sub-opening glue strips 3 sandwiched between the airtight layer 2 and the transition layer 1 and fixedly connected with the airtight layer 2 and the transition layer 1, wherein the two first sub-opening glue strips 3 are respectively located at two sub-opening positions of the inner liner and are parallel to two side edges of the inner liner. In the embodiment, the first seam allowance adhesive tape 3 is directly used as a part of the inner liner and is directly processed between the air-tight layer 2 and the transition layer 1, the inner liner needs to be extended into a film with a certain thickness through a rolling process, and the first seam allowance adhesive tape 3 is tightly pressed between the air-tight layer 2 and the transition layer 1 in the rolling process of the inner liner, so that the strength of the inner liner at a seam allowance part can be improved, the possibility of tilting the first seam allowance adhesive tape 3 can be reduced, the requirement of manually pressing the first seam allowance adhesive tape 3 by workers is reduced, and the production efficiency is improved.

At present, the manual pressing sub-opening rubber strips of workers are required to be lifted up with the tire blank in a state of keeping the axis horizontal, the heads of the workers stretch into the tire blank so as to observe and press the sub-opening rubber, and the tire blank is easy to injure the workers by falling aslant in the pressing process. When the sub-opening glue is pressed manually, in order to enable the sub-opening glue to be smoothly attached to the inner liner and the tire body, workers are inevitably subjected to large pressure, and the sub-opening is easily damaged; the embodiment reduces the need of a worker for manually pressing the first seam allowance rubber strip 3, and also reduces the possibility that the green tire damages the worker and the possibility that the seam allowance is extruded and damaged by the worker.

This embodiment still includes two and transition layer 1 fixed connection's second bead adhesive tapes 4, and two second bead adhesive tapes 4 are close to the both sides limit of transition layer 1 respectively to be parallel to each other with the both sides limit of transition layer 1 respectively. In the embodiment, the strength of the inner liner layer at the seam allowance part is improved by the aid of the second seam allowance rubber strip 4 and the first seam allowance rubber strip 3, so that the first seam allowance rubber strip 3 does not need to be arranged too thick, and the possibility of tilting of the first seam allowance rubber strip 3 is further reduced; and because the second bead rubber strip 4 only plays an auxiliary role, the second bead rubber strip 4 also does not need to be arranged too thickly, and the possibility of the second bead rubber strip 4 tilting is reduced.

Specifically, two accommodating grooves 11 used for accommodating the second seam allowance rubber strip 4 are formed in one side, away from the airtight layer 2, of the transition layer 1, and the two seam allowance rubber strips are fixed in the two accommodating grooves 11 respectively. When the matrix is assembled together with the inner liner, the matrix is closely attached to one side of the transition layer 1 departing from the airtight layer 2, the matrix is blocked at one side of the accommodating groove 11 departing from the airtight layer 2, and the possibility of tilting the second seam allowance rubber strip 4 can be reduced.

Specifically, each second bead adhesive tape 4 is embedded into the corresponding accommodating groove 11, and the groove wall of the accommodating groove 11 clamps the second bead adhesive tape 4 tightly in the accommodating groove 11, so that the possibility of tilting the second bead adhesive tape 4 is further reduced.

This embodiment still includes and is arranged in preventing two second bead adhesive tapes 4 from the reinforcement film 5 of perk in two holding tanks 11, and reinforcement film 5 fixed connection is in transition layer 1 and deviates from one side of air barrier 2 to prevent two second bead adhesive tapes 4 to deviate from in two holding tanks 11, further reduced the possibility of second bead adhesive tape 4 perk.

Specifically, in the present embodiment, two reinforcing rubber sheets 5 are provided, and the two reinforcing rubber sheets 5 are respectively located on one side of the two second seam allowance rubber strips 4 away from the inner liner 2.

Specifically, the two second bead adhesive tapes 4 are not located on the side, away from the airtight layer 2, of the two first bead adhesive tapes 3, so that the two second bead adhesive tapes 4 are prevented from being bent when the two first bead adhesive tapes 3 are bent.

In summary, in the embodiment, the bead filler is directly used as a part of the inner liner, and is directly fixedly connected with the air-tight layer 2 and the transition layer 1, and the bead filler is tightly pressed on the air-tight layer 2 and the transition layer 1 by means of the rolling process of the inner liner, so that the strength of the inner liner at the bead part can be improved, the possibility of tilting of the bead filler can be reduced, the need of manually pressing the bead filler by a worker is reduced, the production efficiency is improved, and the possibility of crushing the tire blank to hurt the worker and the possibility of extruding and damaging the bead are also reduced.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
