[0002] According to Section 4204, "Determination of Leachables in Pharmaceutical Packaging Materials," of the General Chapter IV of the Chinese Pharmacopoeia (2025 Edition), when conducting leachable tests on plastic bottles (such as polyester and polyethylene bottles) used as pharmaceutical packaging materials, it is necessary to cut multiple plastic pieces, each 5 cm long and 0.3 cm wide, according to relevant standards. Currently, this is generally done manually by testing personnel using scissors. This involves cutting a large number of pieces, which is time-consuming. Furthermore, because the plastic pieces are only 0.3 cm wide, it is difficult to guarantee this width manually, and there is a risk of injury when cutting these pieces.

[0003] In view of the above problems, it is necessary to study a bottle cutting device that can cut plastic bottles into multiple plastic strips with a width of 0.3 cm, thereby eliminating the need for test personnel to manually cut the plastic strips, ensuring that the width of the plastic strips meets the requirements and effectively reducing the risk of injury to personnel.
