Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, and more specifically to an automatic cutting device for paper pad strips. Background Art

[0002] Paper strips are often used to separate some electronic products. According to the required size of the product, the paper strips are cut into a suitable width for use in the electronic products. At present, the paper strips are generally cut by a cutting device, which cuts the paper strips into strips of appropriate width. However, since the raw material of the paper strips before cutting is usually in a coiled form with a certain length, most of the existing cutting devices can only cut the paper strips by width. After reaching the appropriate length, the staff still needs to manually cut it. Manual cutting is prone to deviation, which makes it difficult for the cut paper strips to match the electronic products. For this reason, the utility model proposes an automatic cutting device for paper strips. Utility Model Content
