Detailed Description

The invention will be further described with reference to the accompanying drawings, which are provided for illustration of specific embodiments of the invention only and are not to be construed as limiting the invention in any way, the specific embodiments being as follows:

as shown in fig. 1, the molding joint pressing device includes a fixing base 2, the fixing base 2 is fixed on the central column 1 of the laminating drum, and a spherical shell (not shown) is provided on a side surface of the fixing base. The left end of the first connecting piece 3 is provided with the ball head 31 matched with the spherical shell, the ball head 31 is arranged in the spherical shell, the structure can increase the flexibility, the type joint pressing device can flexibly rotate, and a plurality of parts can be pressed according to pressing requirements. The right end of the first connecting piece 3 is hinged with the left end of the second connecting piece 5. The buffer mechanism 6 is fixed to the right end of the second link 5. The press roller 7 is rotatably connected to the buffer mechanism 6. The buffer mechanism 6 can provide a more constant force to the press roller 7, so that the pressing force of the press roller 7 on each layer of tire material joint on the building drum is more stable.

The left end of the tensioning mechanism 8 is fixedly connected with the fixed seat 2, and the right end of the tensioning mechanism is fixedly connected with the second connecting piece 5. The tensioning mechanism 8 can provide tension so that the press roller 7 can always have downward force to further perform auxiliary compression on each layer of tire material joint on the forming drum. The tension mechanism 8 may be an elastic tension structure that provides a stable tension to a tension spring or a tension rubber band, or the like.

The telescopic mechanism 4 is arranged on the hinged rotating surface where the first connecting piece 3 and the second connecting piece 5 are located, is located below the second connecting piece 5, and is hinged with the first connecting piece 3 at the left end and hinged with the second connecting piece 5 at the right end. The telescopic mechanism 4, the first connecting piece 3 and the second connecting piece 5 form a triangular structure. Through the flexible of telescopic machanism 4, can change the contained angle between first connecting piece 3 and the second connecting piece 5, and then make the right-hand member position of second connecting piece 5 carry out corresponding change. Simultaneously, telescopic machanism 4 provides the holding power for between first connecting piece 3 and the second connecting piece 5, reduces the influence of straining force of straining device 8 between to first connecting piece 3 and the second connecting piece 5, makes things convenient for the workman to carry out corresponding operation. The telescoping mechanism 4 can be an electric push rod, an air cylinder, a hydraulic cylinder and the like.

As shown in fig. 2, the buffer mechanism 6 includes a housing 61, an elastic member 62, a stopper 63, and a buffer rod 64. The limiting member 63 is axially arranged perpendicular to the buffer rod 64, and the two are integrally formed. The limiting member 63 may be a limiting rod, a limiting block or a limiting plate. The buffer rod 64 penetrates the housing 61 to be movable up and down in its own axial direction. The elastic member 62 is disposed inside the housing 61 and between the limiting member 63 and the inner wall of the housing 61, and can generate an elastic force to the limiting member 63, so as to buffer the force transmitted by the buffer rod 64. The elastic member 62 may be a compression spring, a rubber spring, a gas spring, or the like, which is capable of providing elastic force.

The working principle is as follows: 8 one end of straining device is connected with fixing base 2, and the other end is connected with second connecting piece 5, can provide stable pulling force for press roll 7 that is fixed in 5 tip of second connecting piece through buffer gear 6 can assist to compress tightly each layer tire material joint on the building drum. The first connecting piece 3, the second connecting piece 5 and the telescopic mechanism 4 form a triangular structure, and the position between the first connecting piece 3 and the second connecting piece 5 can be limited by the supporting function of the telescopic mechanism 4, so that the acting force of the tensioning mechanism 8 is concentrated at the end part of the second connecting piece 5. Meanwhile, the relative position between the first connecting piece 3 and the second connecting piece 5 can be adjusted by means of the telescopic action of the telescopic mechanism 4, so that the position of the compression roller 7 can be conveniently adjusted. The buffer mechanism 6 is connected with the press roller 7, and can buffer the force from the press roller 7 by the buffer action of the elastic piece 62, so that the pressing force of the press roller 7 on each layer of tire material joint on the building drum is more stable.
