Description

Technical Field

[0001] The utility model relates to the technical field of printing and packaging, in particular to a film laminating device for packaging printing. Background Art

[0002] Packaging lamination is a surface processing technology after printing, also known as post-printing lamination, post-printing mounting or post-printing film. It refers to the use of a laminating machine to cover the surface of the printed product with a layer of transparent plastic film to form a paper-plastic integrated product processing technology. As a process for protecting and decorating the surface of printed products, lamination accounts for a large share in post-printing processing. The surface of the printed product after lamination will be smoother, brighter, more stain-resistant, water-resistant and wear-resistant. The colors of the book and magazine covers are more vivid and eye-catching and not easily damaged. The wear resistance, folding resistance, tensile resistance and moisture resistance of the printed products have been greatly enhanced, which protects the appearance of various printed products and increases their service life.

[0003] At present, a Chinese utility model with publication number CN220662013U discloses a laminating device for printing and packaging, comprising an axle, wherein a film is wrapped around the axle, a bottom plate arranged parallel to the axle is provided directly below the axle, and both ends of the bottom plate are connected and fixed with vertically arranged support plates, and upper positions of the opposing surfaces of the two support plates are provided with bayonet holes, one side of the support plate is connected and fixed with a first support arm plate, and one side of the other support plate is connected and fixed with a second support arm plate matching the first support arm plate, a round rod is installed between the first support arm plate and the second support arm plate, a fine hair portion is fixed on the outer surface of the round rod, a plastic sleeve is provided on the round rod that is in sliding contact with the fine hair portion, and a pull-out rod arranged parallel to the round rod is installed at the lower position of the outer surface of the plastic sleeve, and the end of the pull-out rod away from the plastic sleeve passes through a guide hole. The utility model has the following beneficial effects: the end of the film is separated from the film roll, which is convenient for personnel to quickly pull the end of the film and improve the efficiency of laminating.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that although the above equipment can solve the problem that the film needs to be cut after it is pasted on the surface of the printed packaging article, the cut film is easy to adhere to the surface of the rolled film on the shaft again due to its light weight, which requires personnel to spend more time looking for the end of the film, affecting work efficiency. However, during use, the device is not equipped with an auxiliary cutting structure. The user needs to manually cut the film after the existing film is pasted, which not only reduces the accuracy of film cutting, but also reduces the work efficiency of film pasting, while reducing the quality of film pasting.

A servo motor 92 is fixedly mounted on the rear side of the adjustment plate 91. A bidirectional screw 93 is fixedly connected to the output end of the servo motor 92. The front side of the bidirectional screw 93 penetrates to the front side of the inner wall of the adjustment plate 91. Positioning frames 94 are threadedly connected to both sides of the surface of the bidirectional screw 93.

[0025] As a technical optimization scheme of the utility model, by setting a positioning component 9, when the film 4 needs to be cut, the user starts the servo motor 92 on the rear side of the adjustment plate 91, so that the servo motor 92 drives the bidirectional screw 93 to rotate, and drives the positioning frame 94 to move inward through the bidirectional screw 93, so that the positioning frame 94 can position the cutting part, thereby improving the stability of the film 4 when cutting.

[0026] refer to Figure 1 and Figure 4 The replacement component 10 includes a slot 101, which is opened at the top of the adjustment plate 91. The number of slots 101 is set in three groups. The inner wall of the slot 101 is movably connected with an insert block 102. A replacement slot 103 is opened at the top of the cutting knife 8, and the insert block 102 is movably connected to the inner wall of the replacement slot 103.

[0027] As a technical optimization solution of the utility model, by setting up a replacement component 10, the insert block 102 can be effectively inserted into the inner wall of the replacement groove 103 through the slot 101, so that the cutting knife 8 can be fixed.

[0036] The working principle and use process of the utility model are as follows: when in use, the user first rotates the film 4 on the surface of the shaft 3 to pull the film 4 into the inner side of the positioning frame 94, and then measures the film 4 through the scale 17 and the scale groove 18. When the cutting position of the film 4 is determined, the user starts the servo motor 92 on the rear side of the adjustment plate 91, so that the servo motor 92 drives the bidirectional screw 93 to rotate, and drives the positioning frame 94 to move inward through the bidirectional screw 93, so that the positioning frame 94 can position the cutting part, and the anti-slip strip 12 can improve the stability of the film 4 when it is positioned, and prevent the film 4 from sliding or loosening. Phenomenon, and then the limiting rod 14 on the inner wall of the sliding limiting plate is used to limit the two sides of the film 4 to prevent the film 4 from being offset or tilted and causing cutting deviation. Then the user starts the electric push rod 6 on the inner wall of the mounting frame 5, and drives the cutting knife 8 inside the mounting seat 7 through the electric push rod 6 to cut the film 4, thereby improving the cutting efficiency of the film 4 and the accuracy of cutting the film 4, so as to achieve the effect of auxiliary cutting function. When the cutting knife 8 is damaged and needs to be replaced, the user takes out the plug 102 on the inner wall of the replacement slot 103 through the slot 101, so that the user can replace the cutting knife 8 conveniently.

[0037] To sum up: this kind of film laminating device for packaging printing, by setting up a mounting frame 5, an electric push rod 6, a mounting seat 7 and a cutting knife 8, by starting the electric push rod 6 on the front side of the inner wall of the mounting frame 5, the electric push rod 6 drives the cutting knife 8 inside the mounting seat 7, and the cutting knife 8 can cut the film 4, which solves the problem that the device is not provided with an auxiliary cutting structure. After the existing film is coated, the user needs to manually cut the film, which not only reduces the accuracy of film cutting, but also reduces the work efficiency of film coating, and at the same time reduces the quality of film coating.
