[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0028] In the present application, unless otherwise stated, the orientation words such as "up, down, top, bottom" are generally directed to the directions shown in the drawings, or are directed to the vertical, perpendicular or gravity direction of the components themselves. Similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer relative to the contour of each component itself, but the above orientation words are not used to limit the present application.

[0029] In order to solve the problem of poor performance of the cord joint device in the prior art, the present application provides a cord joint device and a tire production system.

[0030] As shown in Figures 1 to 5 The cord joint device in the present application includes a joint frame body assembly 10, a joint pressing plate 20, a material head baffle 30, and a material tail baffle 50. At least a part of the material head baffle 30 and at least a part of the joint pressing plate 20 have a first guide structure 40 that cooperates with each other, and the joint pressing plate 20 and the material head baffle 30 can move relative to each other along the first guide structure 40; the material tail baffle 50 is arranged on the side of the joint pressing plate 20 away from the material head baffle 30; the joint pressing plate 20, the material head baffle 30, and the material tail baffle 50 are respectively connected with the joint frame body assembly 10 and can move relative to the joint frame body assembly 10 in the vertical direction.

[0031] When the cord joint device in the present application is used, the position of the cord joint can be accurately controlled through the cooperation of the joint pressing plate 20, the head end baffle 30 and the tail end baffle 50, and the accuracy and stability of the cord joint are improved. At the same time, through the setting of the first guide structure 40, the joint pressing plate 20 and the head end baffle 30 can move relatively, so that efficient and accurate butt joint of the cord joint is realized, and the production efficiency and product quality are significantly improved. The application of the cord joint device in the present application in the tire production system can further optimize the production process, reduce the waste rate in the production process, reduce the production cost and improve the economic benefit of the enterprise. And since the head end baffle 30 and the joint pressing plate 20 have the first guide structure 40 that cooperates with each other, the cord will not be squeezed between the joint pressing plate 20 and the head end baffle 30 during the lifting or falling of the head end baffle 30 or the joint pressing plate 20, so as to reduce the failure points and improve the joint quality and joint efficiency. Therefore, the cord joint device in the present application effectively solves the problem of poor performance of the cord joint device in the prior art.

The design of the toothed surface can ensure the position accuracy of the cord during the joint, and avoid the misalignment of the cord butt joint due to slight deviation, especially in high-speed vehicle tire production. This high-precision joint is the key to ensuring the stability of the tire during high-speed driving, and has a significant effect on improving the overall performance of the tire.
