Description

Technical Field

[0001] This utility model relates to the technical field of aircraft tire manufacturing, and in particular to a constant pressure injection device for aircraft tire tackifier. Background Technology

[0002] In aircraft tire production, tackifiers need to be precisely injected into the interface between the tire cord layer and the inner liner layer, and the injection needs to be completed within 90-120 seconds after the cord is bonded. Exceeding this time can easily cause the cord pretreatment agent to fail.

[0003] Existing constant pressure injection devices for aviation tire tackifiers, such as the aviation tire ply bonding mechanism disclosed in utility model patent application number 202323611153.3, mainly include a base plate, a vertical plate, a rotating shaft, and a rotating drum. The vertical plate is set at the top of the base plate, and the rotating shaft is rotatably set on the vertical plate. The rotating drum is installed on the rotating shaft, which is driven by a motor. In use, two sets of hoops are fitted onto the rotating drum, and then the rubber parts and ply are wrapped around the two sets of hoops. Adhesive is applied to the outside of the ply, and then the tire rubber layer is wrapped around the outside of the ply.

[0004] However, most existing injection devices are open, making it easy for dust to fall onto the fabric and affect the injection effect. Moreover, most existing tackifier injections are transferred to the spraying station after the fabric layers are bonded, which can easily cause the tire blank to shift. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a constant pressure injection device for aviation tire tackifier that not only isolates external dust and prevents dust from falling onto the curtain fabric, thus ensuring the injection effect of the tackifier, but also eliminates the trouble of transferring the curtain fabric and prevents the cord from shifting during the transfer process.

[0006] This utility model discloses a constant-pressure injection device for aviation tire tackifier, comprising a bonding mechanism; it also includes a sealing mechanism, a feeding mechanism, a storage mechanism, an injection mechanism, and an adjustment mechanism.
