Description

Technical Field

[0001] The utility model specifically relates to the technical field of laser tear lines, and specifically is a laser tear line device for packaging films. Background Technique

[0002] The tear line of a packaging film is a deliberately designed line or area on the packaging film that is easy to tear; without destroying the continuity, the tear line forms a linear structure that is easy to tear, facilitating people to tear open the packaged product, making it more convenient to use and improving the user experience.

[0003] However, the current processing method for traditional tear lines is pressing. The tear line on the packaging film is formed by stamping through a stamping process. During production, the quality of the tear line is affected by the change in the pressure of the equipment. When the punching pressure of the equipment is too large, the packaging film will be cut off, resulting in the inability to guarantee the continuity of the packaging film; when the punching pressure of the equipment is small, the processing and forming of the tear line cannot be effectively guaranteed.

[0004] In view of the above situation, we provide a laser tear line device for packaging films. In this device, the packaging film that needs to be processed with a tear line is transported to the first guiding and driving roller by multiple driving rollers in the transmission assembly, and then transported to the second guiding roller by the first guiding and driving roller, making the packaging film between the first guiding and driving roller and the second guiding roller parallel to the baffle. Then, the processed packaging film is transported to the third guiding roller by the second guiding roller, making the packaging film in a "J" shape when passing through the baffle. The packaging film transported between the first guiding and driving roller and the second guiding roller is processed by laser printing using a laser emitter. During the laser printing of the tear line, the angle of the laser emitter can be effectively adjusted through the spherical adjusting head between the laser emitter and the moving frame. During processing, the movement of the horizontal lead screw driven by the second driving motor can also be used to drive the slider to drive the moving frame to move, thereby effectively realizing the left-right adjustment of the laser emitter to ensure that the laser emitted by the laser emitter is located at the midline position of the packaging film. The movement of the vertical lead screw driven by the first driving motor can also be used to make the moving plate slide up and down along the vertical slide rail installed on the box body through the ear plate and the supporting slide frame, ensuring that the laser emitted by the laser emitter is located at the processing position of the tear line of the packaging film. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a laser tear line device for packaging film.
