Packaging cup sealing device with accurate sealing film alignment and high flatness

Abstract

The invention discloses a packaging cup sealing device with accurate sealing film alignment and high flatness. The packaging cup sealing device comprises a film feeding device, a film collecting device, a packaging cup clamp, a hot-pressing device and a flattening-aligning device, wherein the two ends of a sealing film are connected on the film feeding device and the film collecting device; a to-be-sealed packaging cup is clamped on the packaging cup clamp; the packaging cup clamp is arranged below the sealing film; the hot-pressing device is arranged above the sealing film; the hot-pressing device moves downwards for pressing the sealing film to a cup mouth of a packaging cup; a clamping hole position used for clamping the to-be-clamped to-be-sealed packaging cup is formed in the packaging cup clamp; the inner diameter of the clamping hole position is smaller than the outer diameter of the packaging cup; the flattening-aligning device is arranged above the sealing film; and the flattening-aligning device moves downwards for extruding the sealing film. On the basis of realizing automatic packaging cup film-sealing, cutting and ejecting, the packaging cup sealing device further overcomes the defect that a conventional packaging cup sealing film is liable to have wrinkles and the defect that patterns of the sealing film are not liable to align.

Description

technical field [0001] The invention relates to a packaging cup sealing device, in particular to a packaging cup sealing device with accurate sealing film alignment and high flatness. Background technique [0002] Packaging cup is the general term for various cup-shaped packaging containers used in the packaging industry. It has the characteristics of large mouth and small body. In the traditional packaging form, after filling the material, the mouth of the packaging cup should be covered and sealed. Since the sealing is mostly a hot-pressing process, it is easy to wrinkle the sealing film after the air expands and contracts. Product information etc. are printed on the sealing film, and the buyer will obviously notice that the sealing film is wrinkled when reading the product information, which will bring a perception of poor quality. At present, the wrinkles are mostly eliminated by reducing the pressing temperature, shortening the pressing time, changing the type of film,...

[0002] Packaging cup is the general term for various cup-shaped packaging containers used in the packaging industry. It has the characteristics of large mouth and small body. In the traditional packaging form, after filling the material, the mouth of the packaging cup should be covered and sealed. Since the sealing is mostly a hot-pressing process, the sealing film will easily wrinkle after the air expands and contracts, which will affect the appearance. Product information etc. are printed on the sealing film, and buyers will obviously notice that the sealing film is wrinkled when reading the product information, resulting in a perception of poor quality

At present, the wrinkles are mostly eliminated by reducing the pressing temperature, shortening the pressing time, changing the type of film, etc., but the effect is not good, and it also brings a series of quality problems.

[0003] Moreover, since the product information is printed on the sealing film, when sealing the sealing film on the mouth of the packaging cup, it is necessary to align the part printed with the product information with the mouth of the cup. When the pattern or product information is not pressed against the mouth of the cup , the look and feel of the packaging cup has dropped significantly, bringing a strong sense of inferiority

Most of the current correction systems are adjusted perpendicular to the direction of movement of the sealing film to ensure that the direction of movement of the sealing film is a straight line. There is a lack of a device that can adjust the position of the sealing film in the direction of movement of the sealing film, and there is no device that can adjust the position of the sealing film in the direction of movement of the sealing film.
