Description

Technical Field

[0001] The utility model relates to the technical field of sealing and cutting machines, in particular to an L-shaped sealing and cutting machine for pharmaceutical plastic sealing machines. Background Technique

[0002] In order to ensure the tightness and aesthetics of drug packaging, before the drugs leave the factory, the drugs will be subjected to a plastic sealing packaging, and the film sleeved outside the drugs will be subjected to a sealing and cutting treatment by an L-shaped sealing and cutting machine. The L-shaped sealing and cutting machine has an L-shaped workbench surface, allowing the article to move horizontally on the conveyor belt while also performing a vertical sealing and cutting operation to facilitate the subsequent heat shrinkage of the film.

[0003] When the L-shaped sealing and cutting machine continuously conveys the film, the film will be guided by two triangular plates, and the conveying mechanism is used to intermittently convey the film. Generally, two synchronous belts are set on the equipment to achieve the clamping and conveying of one side of the film. When the L-shaped sealing and cutting machine clamps and conveys the film through two synchronous belts, due to the possible uneven tension of the film material, the force received during the conveying process is uneven, resulting in the displacement of the film. Moreover, if the position of the film material is not properly placed, or the angle of the film material around the triangular plate is not properly adjusted, it may also cause the edge of the film to displace during the conveying process. When the edge of the film displaces, it may cause problems such as machine jamming and shutdown, thus affecting the production efficiency, and also affecting the normal sleeving and sealing and cutting operations of the drugs.
