Description

Technical Field

[0001] The utility model relates to the technical field of color printing carton processing, and particularly relates to a cardboard laminating device for color printing carton processing. Background Art

[0002] A color printing carton generally refers to a paper packaging box printed with color patterns or designs. Such cartons are widely used in the packaging of various products, such as food, cosmetics, electronic products, etc. Color printing cartons can not only protect the products, but also enhance the appearance and brand image of the products.

[0003] Color printing cartons usually adopt high-quality printing technologies, such as offset printing, digital printing, etc., to ensure that the patterns are bright in color and clear in details. During the processing of color printing cartons, a laminating treatment will be carried out, that is, a protective film is laminated on the color printing cardboard to improve the waterproof ability and the like of the color printing carton.

[0004] The existing cardboard laminating device for color printing carton processing does not have a heating structure and cannot heat the protective film, thus unable to improve the laminating efficiency. Therefore, a cardboard laminating device for color printing carton processing is proposed. The protective film is pressed on the color printing cardboard by a first pressure roller for laminating, and the electric heating wire works to heat the heat-conducting silica gel sleeve. During the laminating process, the film can be heated to make it heated and softened, so that the protective film is more easily laminated on the color printing cardboard. Content of the Utility Model

[0005] Aiming at the problems in the prior art, the utility model provides a cardboard laminating device for color printing carton processing. The protective film is pressed on the color printing cardboard by a first pressure roller for laminating, and the electric heating wire works to heat the heat-conducting silica gel sleeve. During the laminating process, the film can be heated to make it heated and softened, so that the protective film is more easily laminated on the color printing cardboard.

[0006] The technical solution adopted by the utility model to solve its technical problems is a cardboard laminating device for color printing carton processing, including a belt conveyor. A laminating assembly is arranged on the top of the belt conveyor. The laminating assembly includes a first gantry fixed to the top of the belt conveyor by bolts. An internally threaded sleeve is welded to the top of the first gantry. A screw rod is sleeved inside the internally threaded sleeve. The bottom end of the screw rod located inside the first gantry is connected to a first structural frame through a bearing. The bottom of the first structural frame is rotatably connected to a first pressure roller through a bearing. A heat-conducting silica gel sleeve is sleeved outside the first pressure roller. Electric heating wires are equidistantly embedded inside the heat-conducting silica gel sleeve;

[0007] On the top of one side of the first gantry of the belt conveyor, a material pressing component is provided. The material pressing component includes a second gantry fixed to the top of the belt conveyor by bolts. At both ends of the top of the second gantry, vertical rods are sleeved through. At the bottom end of the vertical rod inside the second gantry, a second structural frame is fixed by bolts. At the bottom of the second structural frame, a second material pressing roller is rotatably connected through a bearing. Outside the top of the second structural frame of the vertical rod, a compression spring is sleeved.

[0008] By adopting the above technical solution, the compression spring pushes the second material pressing roller downward to press the protective film on the color-printed cardboard. Rotating the screw rod pushes the first material pressing roller downward to tightly press the protective film on the color-printed cardboard for film laminating. The electric heating wire heats the heat-conducting silica gel sleeve, which can heat the protective film to soften it.

[0009] Specifically, at both ends of the top of the first structural frame, first auxiliary rods are connected through threaded grooves. The first auxiliary rods penetrate through the first gantry. At the top end of the screw rod, a rocker is fixedly sleeved through a flat key.

[0010] Specifically, a temperature controller is installed on one side of the first gantry through a mounting seat. The detection end of the temperature controller is located inside the heat-conducting silica gel sleeve. The current output end of the temperature controller is electrically connected to the current input end of the electric heating wire through a power cord.

[0011] Specifically, on the top of the belt conveyor between the first gantry and the second gantry, a cutting component is provided. The cutting component includes a third gantry fixed to the top of the belt conveyor by bolts. Inside the third gantry, a lead screw is rotatably connected through a bearing. On one side of the third gantry, a driving motor is installed through a mounting frame. The output shaft on one side of the driving motor is fixedly connected to one end of the lead screw through a connecting sleeve.

[0012] Specifically, an internally threaded slider is sleeved outside the lead screw. At the bottom of the internally threaded slider, a cutting knife is fixed by bolts. Inside the third gantry at the top of the lead screw, a second auxiliary rod is fixed by bolts. The second auxiliary rod penetrates through the internally threaded slider.

[0013] Specifically, a placement rack is fixed to one end of the belt conveyor by bolts.

[0015] (1) For the cardboard film laminating device for color-printed paper box processing of the present utility model, the set value of the temperature controller is set to control the heating of the electric heating wire. The heat-conducting silica gel sleeve quickly absorbs the temperature after being heated by the electric heating wire, heats the protective film during film laminating to soften it, so that the protective film is more easily adhered to the color-printed cardboard, and the film laminating efficiency can be improved.

[0016] (2) In the cardboard film laminating device for color printing carton processing of the present utility model, the compression spring pushes the second structural frame downward, and the protective film is pressed on the color printing cardboard through the second pressure roller. As the color printing cardboard and the protective film on its top are pushed by the belt conveyor and move into the first gantry, the screw rod is rotated, and the first structural frame is pushed downward through the internal thread sleeve, so that the first pressure roller presses the protective film on the color printing cardboard for film laminating.
