Description

Technical Field

[0001] The utility model relates to the technical field of easy-tear processing of packaging bags, in particular to a novel connecting rod mechanism of an easy-tear integrally formed mold for a plastic packaging bag. Background Art

[0002] Plastic packaging bags are made of plastic as raw material and are used to produce various daily necessities. They are widely used in daily life and industrial production, but this temporary convenience brings long-term harm. Commonly used plastic packaging bags are mostly made of polyethylene film, which is non-toxic, so it can be used to hold food. There is also a film made of polyvinyl chloride, which itself is non-toxic, but the additives added according to the purpose of the film are often harmful to the human body and have certain toxicity. Therefore, this type of film and plastic bags made from this film are not suitable for holding food.

[0003] An easy-tear notch usually refers to a specially designed area on a package or item that is easy to tear. On many product packaging, such as food packaging bags and daily necessities packaging, an easy-tear notch is set to make it easier for people to open the package quickly and easily without the aid of tools, thereby improving the convenience of use. It is generally achieved through special shape design, weak structure or special material processing to achieve the effect of being easy to tear.

[0004] During the processing of the easy-tear edge on the packaging bag, an integrated molding mold is used to punch the packaging bag to make an easy-tear edge. However, the inventors found in their daily work that the mold connecting rod mechanisms in the existing plastic packaging bag easy-tear edge one-piece molding mold industry are all split-type, which will result in a short mold service life during the processing process and a serious waste of raw materials during the machine adjustment process.

Through the above components, when the cylinder is retracting, the cylinder drives the support rod to move, and the support rod drives connecting rod one and connecting rod two to rotate on shaft rod one on the surface of the support seat and the movable seat respectively. When rotating, connecting rod two pushes the movable seat and slider one downward to move on the slide rail, and the upper mold knife seat cooperates with the lower mold knife seat to perform stamping to form an easy-to-tear opening.
