The utility model relates to the technical field of film laminating equipment, and discloses plastic packaging box film laminating equipment which comprises a supporting bottom plate, a heating and cooling mechanism is fixedly connected to the interior of a first supporting base and the interior of a second supporting base, and a cooling fan is fixedly connected to the side, away from the second supporting base, of the second supporting base. A heating fitting column is rotatably connected to the interior of the heat dissipation fan, a cooling plate is fixedly connected to the top side of the interior of the second supporting base, and supporting connecting plates are fixedly connected to the interiors of the two sides of the second supporting base. According to the utility model, through the heat dissipation fan and the heating fitting column, rapid film laminating and fitting on the surface of the plastic box are realized under different conditions, the cooling plate and the heat dissipation holes work cooperatively, heat is absorbed and dissipated effectively, the electric telescopic column and the rolling column further flatten the surface of the plastic box, the film laminating and fitting quality is improved, and the production efficiency is improved; and it is ensured that the surface of the plastic box reaches the optimal flatness and attractiveness after being cooled.

This application relates to a spacing adjustment device, a cabinet, and a refrigerator, specifically in the field of refrigerator technology, and aims to provide a device for facilitating the adjustment of the spacing between the door and the cabinet when closed. The spacing adjustment device includes a housing, a support assembly, and an adjustment assembly. The housing has an adjustment cavity, and a first insertion hole and a second insertion hole communicating with the adjustment cavity. A portion of the support assembly is located within the adjustment cavity, and another portion of the support assembly extends out of the adjustment cavity via the first insertion hole. A portion of the adjustment assembly is inserted into the second insertion hole, and a portion of the adjustment assembly is located within the adjustment cavity. The adjustment assembly is configured to have a switchable first state and a second state. When the adjustment assembly is in the first state, the portion of the adjustment assembly located in the adjustment cavity is drively connected to the support assembly to adjust the insertion depth of the support assembly within the first insertion hole. When the adjustment assembly is in the second state, it prevents the adjustment assembly from driving the support assembly to adjust the insertion depth within the first insertion hole.
