Embodiment Construction

[0009] Such as figure 1 As shown, the present invention includes a base 1, a film guide roller 2, and a spiral groove 3, and is characterized in that: the base 1 is provided with a film guide roller 2, and the film guide roller 2 is provided with a spiral groove 3 around it. The rotation direction of both ends of the spiral groove 3 is symmetrical along the center of the film guiding roller 2 .

[0010] Working principle of the present invention: the stretched film passes through the lower side of the film guide roller 2, and when the stretched film twitches, it drives the film guide roller 2 to rotate, and the external expansion force generated when the spiral groove 3 on the film guide roller 2 is used to rotate The stretch film is stretched to both sides to prevent the stretch film from curling after entering the working room.

Abstract

The invention discloses a film guide roller of a stretch film packer. The film guide roller comprises a base, a film guide roller and spiral grooves, and is characterized in that the film guide roller is arranged above the base, wherein the spiral grooves are formed around the film guide roller; and the rotating directions at the two ends of the spiral grooves are horizontally symmetric about the center of the film guide roller. The film guide roller of the stretch film packer has the following beneficial effects: external expansion force generated by rotating the spiral grooves stretches a stretch film to two sides to prevent the stretch film from being wound after entering a studio, so that the surface of a product package is prevented from generating drapes; and meanwhile, traditional equipment is little modified, the modification cost is low, and the promotion and the modification are facilitated.

Description

technical field [0001] The invention relates to a film guiding roller, in particular to a film guiding roller of a stretch film packaging machine. Background technique [0002] At present, the stretch film on the ordinary stretch film packaging machine enters the heat sealing studio of the packaging machine, and the upper film curls due to the stretching force, resulting in wrinkles on the surface of the product after packaging, resulting in waste products and increasing production costs. . Contents of the invention [0003] The purpose of the present invention is to provide a film guide roller of a packaging machine that can prevent the upper film from being curled due to force stretching after the stretched film enters the heat-sealing working chamber of the packaging machine. [0004] In order to achieve the above object, the technical solution of the present invention includes a base, a film guide roller, and a spiral groove, and it is characterized in that: a film gu...
