Background technique

In semi-steel radial tires, the carcass ply is the main stress-bearing part, which bears extremely complex forces such as periodic stretching, bending, and shearing, and is the stress-bearing skeleton layer of the tire. The quality of the carcass cord directly affects the performance and quality of the tire to ensure that the tire has the necessary strength and dimensional stability. Its strength and elasticity can withstand complex stress and strain when the tire is in use, and ease the vibration and impact of the external road surface. Its performance determines the quality and performance of the tire.

The tire manufacturing company uses a cord cutting machine to cut the cord into rectangular cord strips according to the width requirements set by the process, and then automatically laps the cut cord strips in turn, and finally curls them into certain required rolls for the forming machine.

At present, the radial tire cord cutting machine has the following problems: slow lap joint speed, low positioning accuracy, etc., which cannot meet the increasing needs of output and quality.

At present, the lap joint device of the cord cutting machine uses a cylinder or other linear motion elements to drive the pressure plate to move up and down to perform pressing, and presses and presses the lap joints of the cords that have been put together.

The conveying mechanism 52 has the functions of automatic deviation correction and material edge detection, so as to ensure that the material edge position of the cord conveying remains unchanged . The cutting mechanism 53 is located behind the conveying mechanism 52 along the direction of material introduction, and is used for cutting the cord with a predetermined length to form a cloth strip 90 to be overlapped. The leading material mechanism 54 is positioned at the back of the cutting mechanism 53 along the material leading direction, and after it utilizes the clamps to clamp the cord, the cord is pulled out from the cutting mechanism 53 by a set length, so that the cutting mechanism 53 can cut to length.

When crimping is not required, the telescopic driver 18 pushes up the upper rolling roller 11 to allow the cloth strip 90 to be overlapped to pass through. The pressure roller 11 and the lower rolling roller group 12 form a crimping gap, which compresses the overlapping positions of the two cloth strips 90 to be overlapped.
