Cutting tool bit for point broken line of packaging bag

Abstract

The invention discloses a cutting tool bit for a point broken line of a packaging bag and relates to a cutter for producing plastic packaging bags. The cutting tool bit comprises a long-plate shaped cutter body, wherein a plurality of tool bits are arranged on the cutter body; the cutting tool bit is characterized in that: partition slots are formed among the plurality of tool bits, so that the tool bits can be separated from one another; an inclined surface is formed on the end face of one lateral end of each tool bit; and an inclination angle formed between the inclined surface and each tool bit is 20 to 40 degrees. The cutting tool bit for the point broken line of the packaging bag has the advantages that: the point broken line of a cut plastic bag is easy to break, and harm to the plastic bag can be avoided.

Description

technical field [0001] The invention relates to a cutter used in the production of plastic packaging bags. Background technique [0002] In the production of plastic packaging bags, some plastic bags are not cut off, but connected to each other, such as the packaging bags used in supermarkets, which are wound into rolls. For ease of use, a dotted line is cut at the bottom of each plastic bag so that it can be broken from the dotted line by simply pulling the plastic bag. However, due to the unsatisfactory cutting ratio of the broken line, it is not easy to break when pulling the plastic bag, and even with a little force, the plastic bag is pulled and damaged, which affects the use. Contents of the invention [0003] In order to solve the above problems, the present invention provides a cutting cutter head for broken lines of packaging bags, which can make the broken lines of cut plastic bags easy to break without affecting the use of plastic bags. [0004] In order to ac...
