Problems solved by technology

[0002] Because nylon film has good oil resistance and heat resistance, it is widely used in packaging fried food. In order to facilitate food packaging, a slitter is used to cut the film into appropriate sizes according to the volume of the food. Nylon film is placed on the film frame of the cutting machine, and the rotating roller drives the film to be conveyed through the slitting knife for slitting; in the prior art, when the slitting machine is used to slit the nylon film, because the nylon film is easy to absorb moisture, when the moisture in the air When the content is large, the nylon film absorbs water molecules in the air, causing the film to stick to the surface of the rotating roller, and the friction coefficient increases, the conveying speed of the rotating roller to the film slows down, and the cutting position is prone to misalignment, resulting in the size of the slitting film. Different sizes, affect normal on food packaging

Abstract

The invention discloses film slitting equipment which structurally comprises a base, machine bodies, a film frame and a motor. The machine bodies are installed at the tops of the two ends of the base respectively; and the film frame is horizontally fixed between the machine bodies. Due to the fact that a nylon film absorbs moisture in air, the film is attached to the surface of a rotating roller; a pushing ball of a vibration mechanism moves in a supporting ring under the action of centrifugal force to impact a deformation block, so that airflow in the deformation block is discharged along an opening, a film attached to the outer wall of the rotating roller is separated from the rotating roller under the thrust of the airflow, the conveying speed of the rotating roller to the film is increased, cutting position dislocation is reduced, the sizes of the slit films are kept the same, and food can be normally packaged; and due to the fact that liquid in the films drips downwards under the extrusion force of the rotating roller, the liquid dripped from the films is collected through an accumulation cavity formed in the opening, so that liquid gathering on the outer wall of the rotating roller is reduced, friction force between the films and the rotating roller is reduced, and the film conveying speed is increased.
