Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tire manufacturing, in particular to a belt layer joint device. Background Art
[0002] Tires are the parts of automobiles that are in direct contact with the ground, and their performance directly affects the safety of the car. The belt cutting process is a very important process in tire production. During the cutting and splicing process, specifically, the belt joint splicing process is to splice the belt joint formed by the tail part of the previous belt layer and the head part of the next belt layer. If the joint quality is unstable, it is easy to have poor conditions such as virtual joints or overlaps at the belt joints, which will lead to quality defects such as poor X-ray detection and uniformity dynamic balance detection of the finished tire. In the prior art, the joint mechanism of the traditional cutting equipment generally uses a single set of umbrella wheels for sewing operations. When there is a deviation in the feeding position of the belt layer, direct sewing operations are likely to cause overlapping of the belt joints. When there is an abnormal amount of warping after the belt layer is cut, the umbrella wheel directly presses down to sew, which is easy to cause the belt joint to be dislocated and the local overlap is poor, thereby affecting the quality of the finished tire.

[0029] During operation, the umbrella wheels 6 and the front pre-pressure roller 4 are pressed down to the surface of the cord fabric. The separating knife 5 drops to the middle of the front and rear joint cord fabrics to play a partitioning role. The front pre-pressure roller 4 first flattens the surface of the belt layer, and then the umbrella wheels 6 perform joint stitching to complete the belt layer joint operation.
[0030] It can be understood that the umbrella wheel bracket 2 and the front cylinder 3 are firmly installed on the combined bracket 1 to ensure that the front cylinder 3 and the umbrella wheel bracket 2 do not shake and are stably installed.

[0042] The working principle of this embodiment:
[0043] During operation, after the belt layer is cut, it is conveyed under the joint machine. The combined support 1 drops under the action of the first cylinder 10. Under the action of the bevel gear 6 and the separating knife 5, the front and rear cord fabric joints are butted and sewn to ensure that there is no overlapping phenomenon at the joint. At the same time, the front pre-pressing roller 4 is driven by the front cylinder 3 to lift and lower. For the cutting warping of the head and tail materials of the large rolling curtain caused by the tension fluctuation, during the joint splicing process, the cord fabric warping is first processed by the front pre-pressing roller 4, and then the splicing operation is carried out under the action of the bevel gear 6, avoiding the virtual connection or overlapping of the joint caused by the warping, ensuring the stability of the belt layer joint quality, helping to improve the product quality, improving the production efficiency, reducing the waste of raw materials caused by the belt layer joint problems, and reducing the production cost.
