Description

A double-station roll-changing mechanism and edge material winding machine

Technical Field

The utility model relates to the technical field of edge material winding equipment, in particular to a double-station roll-changing mechanism and an edge material winding machine.

Background Art

In the production of film, it is necessary to trim the irregular edges on both sides of the film so that the film can be neatly rolled up and the quality of the film roll can be improved. The continuous edge material formed after the existing film trimming is usually processed in the following two ways: first, the edge material is guided back to the beginning of the production line for recycling through online recycling; second, the continuous edge material is rolled up.

The existing edge material rewinder has only one rewinding shaft. When changing the roll, the machine needs to be stopped, the roll needs to be unloaded, and a new paper core needs to be put on before rewinding. However, in this production line, the film is constantly flowing out of the front-end equipment. Therefore, the edge material generated during the edge material stoppage and rewinding process can only be placed anywhere, which increases the operator's work of sorting the edge material later.

It can be seen that the existing technology still needs to be improved and enhanced.

Similarly, when the second winding shaft 7 is winding, the second rotating mechanism 5 drives the fourth driven wheel 51 to rotate. Since the fourth driven wheel 51 and the third driving wheel 72 rotate synchronously, the second winding shaft 7 is driven to rotate under the cooperation of the third driving wheel 72, the third driven wheel 71 and the third synchronous belt 73, so that the edge material can be continuously wound after automatic reel changing.

Similarly, the second rotating mechanism 5 drives the fourth driven wheel 51 to rotate, and drives the second reel 7 to rotate with the cooperation of the third driving wheel 72, the third driven wheel 71 and the third synchronous belt 73, so that the edge material can be rewound onto the paper tube core located on the second reel 7.
