Technical Field

[0001] The utility model relates to the field of tire production equipment, in particular to an edge wrapping device and a tire production system. Background Art

[0002] The belt layer plays a vital role in the tire production process. The belt layer is produced by cutting the steel cord into cord strips according to the angle and width required by the tire process, and then feeding, splicing, unloading, wrapping and adhering the cord strips, and finally winding them onto the trolley. With the market demand for giant tires and process innovation, the requirements for the width of the belt layer are constantly increasing.

[0003] The belt layer edge wrapping and wedging process is completed by the edge wrapping device. The spliced ​​belt layer is centered by the mechanical centering mechanism of the edge wrapping device, and then the film is laminated and compacted on the edge wrapping conveyor belt. After the padding attached to the film is peeled off, it is wrapped by the edge wrapping mechanism and compacted by the rear drive roller to complete the edge wrapping process. The above-mentioned film can be laminated from outside or inside the line. At present, the maximum width of conventional all-steel belt layers or engineering tire belt layers is 850mm. Now the width required for giant tires is between 200mm-1350mm. In addition, the existing giant tire hemming device generally adopts a centering hemming structure, in which the center of the belt layer coincides with the center of the conveyor belt and the hemming mechanism for the hemming process, and there are the following problems: since the belt layer is wide, the required conveyor belt width is also wide, and the edge of the belt layer on the non-operating side is always on the other side of the center of the conveyor belt, resulting in inconvenient operation; and because the belt layer process between 200mm-1350mm must be met, when the belt layer is wider than 850mm, there is too much overhang in the middle, and the belt layer will collapse and twist, thereby affecting the completion of the hemming process.

[0004] Therefore, there is a problem in the prior art that the giant tire welting device has poor performance. Utility Model Content

[0026] In order to solve the problem of poor performance of giant tire edge wrapping devices in the prior art, the present application provides an edge wrapping device and a tire production system.

[0027] Furthermore, the tire production system in the present application includes the following edge wrapping device.

[0028] like Figure 1 to Figure 2 As shown, the edging device in the present application includes a feeding assembly 10, an edging conveyor belt assembly 20, and an edging assembly 30.

[0029] When the hemming device in the present application is used, since there is a feeding assembly 10 and the feeding assembly 10 is arranged near the feed end of the hemming conveyor belt assembly 20, the film and the belt layer can be respectively conveyed to the hemming conveyor belt assembly 20 by the feeding assembly 10, and the belt layer can be conveyed to the hemming assembly 30 by the hemming conveyor belt assembly 20 for hemming operation. At the same time, since the hemming assembly 30 has a first hemming portion 31 and a second hemming portion 32, and the first hemming portion 31 is arranged at the edge of the hemming conveyor belt assembly 20, in the present application, the operating side of the belt layer can be hemmed by the first hemming portion 31, and the second hemming portion 32 corresponds to the non-operating side of the belt layer. At this time, during the process of conveying the belt layer through the hemming conveyor belt assembly 20, the operating side of the belt layer can be conveyed along the edge of the hemming conveyor belt assembly 20.

That is to say, the edge wrapping and wedging device in the present application completes the edge wrapping and wedging process of the belt layer in the form of fixed edge, which can avoid the problem that the non-operating side is always on the other side of the center of the conveyor belt compared with the traditional fixed centering form. At the same time, it is more convenient to operate. Therefore, the edge wrapping and wedging device in the present application effectively solves the problem of poor performance of the giant tire edge wrapping and wedging device in the prior art.

[0030] In the present application, the hemming assembly 30 also includes a driving unit 200, and the driving unit can drive the second hemming unit 32, so as to ensure that the second hemming unit 32 can move relative to the first hemming unit 31.
