Description

Technical Field

[0001] The invention belongs to the technical field of tire production, and in particular relates to a slitting and guiding device based on the linkage production of wide cord fabric and narrow cap band. Background Art

[0002] The existing tire production process requires the combination of a wider cord layer and two narrower cap layers. Both the cord layer and the cap layer require longitudinal cutting machines to cut out the blanks. The cap layer roll and the cord roll are divided into two layers of telescopic feeding ends, which are sequentially wound and bonded into shape during the tire molding process.

[0003] Regarding the cutting of the crown layer, since the crown layer is narrow, the number of coils cut out is large. If a 22-station slitting machine is needed to reel the crown layer, the operation is cumbersome and occupies a large area.

[0004] If the cord layer and the cap layer are produced in conjunction (including the unloading process), the tire production efficiency can be greatly improved. In this process, if the belt body blank is cut into multiple sub-belt bodies, and then the sub-belt bodies are cut into two cap layers and one cord layer for centralized cutting, the number of rolls can be greatly reduced and there is no need for cutting and winding the cap layer, which greatly improves the production efficiency and the floor space occupied by the equipment.

[0005] However, the difficulty in the above process is that if the cord layer and two cap layers are cut and directly conveyed to the forming process, the cap layers are located on both sides of the cord layer, which are too far away from the two sides of the forming drum, which is not conducive to the positioning, guiding and subsequent forming and winding of the cap layers. Therefore, designing a specific material guiding device is a problem that needs to be solved by the staff in this field. Summary of the invention

[0006] The purpose of the present invention is to provide a slitting and guiding device based on the joint production of wide cord and narrow cap layer, by eliminating the separate longitudinal slitting, striping and winding of the cap layer, so that the cap layer and the cord layer are combined in front of the forming equipment for joint slitting and material guiding, the occupied belt body width is large, which is conducive to the longitudinal slitting and winding of the raw material blank, greatly improving the production efficiency, and reducing the floor space occupied by the equipment.
