TECHNICAL FIELD
[0001] The utility model relates to a tire production equipment technical field, concretely relates to a joint mould that improves inner tube welding quality, simple structure, positioning is reliable, convenient to change mould, high joint efficiency. BACKGROUND
[0002] In the production process of the inner tube for vehicle, the inner tube sleeve is extruded by the extruder, and then is connected on the inner tube joint machine to form a ring-shaped inner tube semi-finished product, and then is vulcanized and installed with a valve to form a finished inner tube. Therefore, the quality of the inner tube joint is the key to determine the quality of the finished inner tube. The inner tube joint mould is an important tool for connecting the two ends of the inner tube sleeve to form a ring-shaped inner tube in the inner tube joint machine, and the structure of the inner tube joint mould determines the quality and efficiency of the inner tube joint.
[0003] The traditional joint of the inner tube for vehicle is usually manually operated by a pressure roller. Since the temperature, pressure and time during the joint of the inner tube sleeve are only controlled by the intuitive feeling of the operator, it is difficult to control the joint, which may cause the joint to be not firm, the joint to crack, and the joint to have low adhesive strength. Therefore, the production efficiency is low, and the quality of the joint is unstable.
[0004] At present, when the inner tube for vehicle is connected to form a ring, the inner tube joint machine is generally used for welding. During the welding, the inner tube sleeve is positioned by fixed blocks and movable blocks arranged on the frame of the joint machine, and a pressing block is used to press the sleeve, so that the two ends of the sleeve are pushed against each other to be welded by the movable blocks and the corresponding pressing blocks. Since the inner tube sleeve is positioned by the fixed blocks and the movable blocks, the corresponding fixed blocks and movable blocks need to be replaced for different specifications of the inner tube. Since the fixed blocks and the movable blocks need to have a space for operation, a complex cantilever structure is formed, and the operation is difficult when the fixed blocks and the movable blocks are replaced. Therefore, in the prior art, adjustable positioning width movable structures are arranged on the fixed blocks and the movable blocks, respectively, to adjust the movable structures to meet the positioning needs of different specifications of the inner tube, so as to solve the problems of frequent replacement and inconvenience of replacement of the blocks. However, since the movable structures are usually connected by guide rails and sliding blocks, the inner tube is usually sprayed with an anti-sticking agent to prevent sticking. When the anti-sticking agent on the inner tube dissolves, it is easy to fall into the gap between the guide rail and the sliding block, which makes it difficult to adjust the width and even causes the movable structure to be stuck. In order to adjust the width smoothly, the gap between the guide rail and the sliding block is usually increased. Although this basically solves the problem of being stuck, the large gap will cause the positioning surface to be inclined and affect the positioning accuracy, which reduces the reliability of the positioning.
