Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of decorative film production and processing, in particular to a film laminating device for decorative film production. BACKGROUND

[0002] The decorative film is a new type of decorative material made of high molecular polymer (PVC) as raw material, adding various additives, and being compounded by calendering. It can be compounded with wood, plastic board, aluminum plate, iron plate and other base materials to make multi-purpose decorative materials, which are widely used in household appliances, surface decoration of sound, indoor decoration, interior decoration of airplanes, ships and trains. In addition, it can also be used for billboards, etc. The adhesive process of the decorative film refers to the process of pre-gluing the decorative film and then compounding it with the film. First, the glue solution is applied to the decorative film, then the glued decorative film is compounded with the film provided by the user with the manufacturer's printed matter, and finally the compounded decorative film is wound.

[0003] For example, the Chinese patent with publication number CN215551725U discloses a decorative film adhesive device for bonding decorative film. The adhesive device for decorative film includes a rack, a glue applying assembly and an adhesive assembly. The glue applying assembly includes a glue applying roller, which is in contact with the decorative film. The adhesive assembly includes a support, a fixed roller, a contact roller, a film roller, a contraction rod, an adjusting piece and an elastic piece. The contact roller is arranged opposite to the fixed roller. The film roller is arranged on one side of the fixed roller. The contraction rod includes a fixed rod and an adjusting rod. The adjusting rod includes a smooth section and a threaded section. The smooth section extends into the fixed rod. The threaded section is fixedly connected with the support. The adjusting piece is sleeved on the threaded section. The elastic piece is elastically arranged between the adjusting piece and the fixed rod. By rotating the adjusting piece, the fixed rod moves up and down due to the elastic effect of the elastic piece. The fixed rod drives the contact roller to move up and down, adjusting the distance between the contact roller and the fixed roller to adapt to different types of decorative film, which has good versatility and prevents bubbles from occurring between the decorative film and the film.

[0004] After the production of the decorative film is completed, some residual impurities and dust will be left on the surface of the decorative film, and if the dust on the surface of the decorative film is not treated before bonding, the dust will affect the gluing effect, and bubbles will still occur between the decorative film and the film. In addition, in the patent, the gluing assembly comprises a glue bin, a gluing roller and gluing cotton, the glue bin is arranged on the rack, the gluing roller is rotatably arranged on the rack, wherein the gluing roller is located at the top of the glue bin, and the top of the gluing roller abuts against the decorative film, so that the gluing roller can uniformly glue the surface of the decorative film, the gluing cotton is arranged in the glue bin, one end of the gluing cotton abuts against the bottom wall of the glue bin, and the other end of the gluing cotton abuts against the gluing roller. In order to fully utilize the glue in the glue bin, the cross section of the groove bottom wall of the glue bin is in a trapezoidal shape, and the two waists of the trapezoidal shape are in an inclined structure, and the gluing cotton abuts against the bottom wall of the trapezoidal shape. Therefore, when the glue in the glue bin is less, the glue at the bottom of the glue bin is gathered at the bottom wall of the trapezoidal shape, so that the gluing cotton can fully absorb the glue in the glue bin. However, when the glue in the glue bin is less, only the gluing cotton can fully absorb the glue in the glue bin, and the glue absorbed on the gluing cotton cannot be completely applied to the gluing roller, causing waste of glue.
