Description

Butt splicing device for roll-to-roll process

This creation is about a butt-joint film splicing device for the roll-to-roll process, especially the roll manufacturing equipment for splicing two rolls of film materials. It can smoothly connect the old materials and prepare materials during the uninterrupted production process, so as to improve the quality of the rolls. The productivity efficiency of manufacturing equipment and the film material bonding device that reduces the loss of production materials.

The butt-joint film splicing device of this roll-to-roll process usually consists of the tail end of the old film in one direction and the new film to be continued along this direction, and a double-sided tape is pasted on the upper part of the overlap between the old and new film, and along the direction The direction front tape is attached to the tail end of the membrane material for reinforcement. In the known structure, when the material membranes are connected, double-sided adhesive tape is used to bond or rely on the reinforcing tape, so a thicker connection section is formed at the butt joint of the old and new membrane materials.

In the known device, the old film material that is about to be used up and the new film material that needs to be replaced are overlapped and connected with adhesive tape, so a thicker connection section is formed at the junction of the old and new film materials, which is easy to cause damage after winding. The film roll for storing the film roll cannot be rolled up smoothly, and the joint convex part will also cause indentation of other film materials, resulting in defective products and increased loss.

In addition, the traditional film splicing device rolls the old and new web materials to form a thicker connection section at the junction of the old and new web materials. In other roll-to-roll processes such as coating, slitting,,,,, etc., it is easy to cause mistakes and break the film , The frequent occurrence of the above situations will cause the machine to crash and stop running, which will delay the operation of the production line, and may even cause damage to the machine in severe cases.
