Packaging box film coating and sealing device suitable for different sizes

Abstract

The invention provides a packaging box film coating and sealing device suitable for different sizes. The packaging box film coating and sealing device comprises a bottom plate, a conveying belt, a clamping mechanism, a film coating mechanism and edge sealing mechanisms. The two edge sealing mechanisms are mounted on the bottom plate. The clamping mechanism is mounted on the bottom plate and comprises hydraulic cylinders, a linear drive mechanism, guide rails, sliding blocks, single-axis air cylinders, rotating air cylinders and ejector rods. The film coating mechanism is mounted on a supporting frame and comprises an air bellow, an air pipe, a fan, a hot knife, a dual-axis air cylinder I and a winding roller. A packaging box is clamped by the oppositely-arranged ejector rods, the packagingbox is driven to rotate under the action of the rotating air cylinders, and then packaging boxes of different sizes can be clamped; then, the surface of the packaging box is wrapped by a layer of packaging film, and the situation that bubbles are generated in the film coating process to influence packaging is avoided; the fan inputs negative pressure into the air bellow, and the packaging film isclosely attached to the air below; and when film cutting is carried out on the packaging box with packaging completed, later packaging boxes can continue to be packaged, and packaging efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of packaging equipment, in particular to a film-coated sealing device suitable for packaging boxes of different sizes. Background technique [0002] In the field of packaging, various materials are widely used, among which cardboard materials are widely used for their environmental protection characteristics, good performance and low cost. Products can be packaged by processing cardboard into boxes or boxes, but After the packaging is completed, the packaging box also needs to have good pressure resistance, waterproof and moisture-proof properties, and then needs to be covered with a film on the outside of the carton to achieve the waterproof and moisture-proof effect. [0003] Publication No. CN106275639B provides a segmented packaging film automatic positioning and laying device for a cylindrical box body. This device rotates through the box body driven by a negative pressure suction cup, and gradually wra...

Problems solved by technology

[0003] Publication No. CN106275639B provides a segmented packaging film automatic positioning and laying device for a cylindrical box body. This device rotates through the box body driven by a negative pressure suction cup, and gradually wraps around the entire box body. When the box body When the shape is irregular, the negative pressure suction cup cannot hold the box tightly and cannot be laminated
