Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a film-covering and sealing device for food packaging and processing. Background Art

[0002] Food packaging box lamination is also called "film pasting". The specific operation is to use transparent plastic film to seal the top of the food packaging box through hot pressing so as to use it for food fresh-keeping packaging. If you want to laminate the food packaging box, you will inevitably need to use laminating and sealing equipment for food packaging processing.

[0003] Existing equipment mostly uses a pressing plate and a hot pressing mechanism and a cutting mechanism to reciprocate up and down to perform lamination. Although this method can perform lamination processing, it is inevitable that there are still some shortcomings in its actual use. For example, the device lacks an adaptive displacement mechanism, so that after the food packaging box is laminarized, it will not be able to leave the transparent film processing range in time, resulting in inconvenience in its removal and replacement. In order to avoid such problems, a laminating and sealing device for food packaging processing is proposed to solve the existing problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a film coating and sealing device for food packaging processing, which solves the problem that the device lacks an adaptive displacement mechanism, resulting in the inability to promptly remove the food packaging box from the transparent film processing range after coating, making it inconvenient to remove and replace it.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a film coating and sealing device for food packaging processing, comprising a workbench and a processing frame, wherein two processing frames are provided, and the two processing frames are elastically slidably arranged on both sides of the top of the workbench, the top of the workbench is fixedly connected to an electric telescopic rod through a bracket, the bottom of the extended end of the electric telescopic rod is fixedly connected to a pressing plate, and the bottom of the pressing plate is provided with a processing mechanism used in conjunction with the processing frame, the two processing frames are fixedly connected to guide rollers on the opposite sides, and L-shaped extrusion rods used in conjunction with the guide rollers are fixedly connected to both sides of the pressing plate, and an ejection mechanism is provided between the processing frame and the pressing plate.

[0006] Preferably, the processing mechanism includes a limiting sleeve, four limiting sleeves are provided, and the four limiting sleeves are all provided at the bottom of the pressure plate, the limiting sleeve is internally slidably connected to a limiting telescopic rod, a second return spring is fixedly connected between adjacent limiting telescopic rods and the limiting sleeve, the bottoms of two adjacent limiting telescopic rods are commonly fixedly connected to a heating press plate, and the bottom of the pressure plate and the outer surface of the heating press plate are fixedly connected to a cutting knife through a bracket.

[0007] Preferably, the ejection mechanism includes a limiting cylinder, two limiting cylinders are provided, and the two limiting cylinders are respectively fixedly arranged on the opposite sides of the two processing frames, the limiting cylinder is internally slidably connected to a limiting slide rod, a third return spring is fixedly connected between the limiting slide rod and the limiting cylinder, a special-shaped U-shaped rod is fixedly connected to the bottom of the limiting slide rod, a support plate is provided on the top of the special-shaped U-shaped rod and located inside the processing frame, and a pressing handle used in conjunction with the special-shaped U-shaped rod is fixedly connected to the front side of the L-shaped extrusion rod.
