Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of the production of easy-to-tear packaging bags. More specifically, the utility model relates to an on-line manufacturing device for easy-to-tear packaging bags. Background Art
[0002] An easy-to-tear packaging bag is a packaging bag that is easy to open. The most prominent feature of an easy-to-tear packaging bag is the presence of an easy-tear opening. This design element allows consumers to easily open the bag without using any tools such as scissors. The easy-tear opening is usually made of a special material with a low tear strength and can be neatly torn along a predetermined path.
[0003] When the existing easy-to-tear packaging bags are produced, intermittent tear lines can be formed on the packaging bags by means of mechanical gear rolling. Without being torn, these roll-formed intermittent tear lines can maintain the sealing performance of the packaging. However, before rolling, it is not convenient to guide the packaging bags, and the packaging bags are prone to deflection, resulting in poor use effects. Summary of the Utility Model

A first heat-sealing assembly is arranged on the first fixing frame, and the first heat-sealing assembly includes a second hydraulic cylinder and a transverse heat-sealer.
[0010] Furthermore, the top end of the second hydraulic cylinder is fixedly connected to the first fixing frame, and the bottom end of the second hydraulic cylinder is fixedly connected to the transverse heat-sealer.

A second heat-sealing assembly is arranged on the second fixing frame, and the second heat-sealing assembly includes a third hydraulic cylinder and a longitudinal heat-sealer.
[0013] Furthermore, the top end of the third hydraulic cylinder is fixedly connected to the second fixing frame, and the bottom end of the third hydraulic cylinder is fixedly connected to the longitudinal heat-sealer.
[0014] It can be seen that in the above technical solution, the longitudinal heat-sealer longitudinally seals the packaging bag.
