Preferably, the plates of the barrel body and the end cover are metal plates, and the thickness of the metal plates is 0.6 mm-1.2 mm; the thickness of the film coating layers on the back surfaces of the two end covers is 0.06-0.1 mm.

Preferably, the heating temperature of the heating part for the two end covers is 110-260 ℃.

Preferably, the heating part is a high-frequency heating pipe or an electric heating pipe.

Preferably, the film coating layer is one of a PET film and EVA film combination, a PET film, a PE film, a PP film or a PA film.

Compared with the prior art, the utility model has the advantages that:

(1) According to the heating device for the curled cover of the film-covered barrel, disclosed by the utility model, the film-covered layers on the adjacent barrel bodies at the curled edge are fused with the film-covered layers on the end covers by heating instead of simple extrusion and then are attached to each other, so that the two ends of the barrel bodies are sealed, and the film-covered barrel can still maintain good sealing performance after long-term practical use.

(2) In the utility model, the thickness of the film layers on the back sides of the two end covers is 0.06 mm-0.1 mm, so that the film layers on the adjacent barrel bodies at the curled edges and the film layers on the end covers can be better fused, the thickness of the film layers on the back sides of the two end covers is thickened, and further, the good sealing of the two ends of the barrel bodies is realized.

Detailed Description

The following describes the present utility model in further detail with reference to specific examples:

in the description of the utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," etc. indicate or are based on the orientation or positional relationship shown in the drawings, merely for convenience of description and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the utility model.

As shown in fig. 1 and 2, a heating device for a curled cover of a film-covered barrel comprises a barrel body, wherein end covers 5 are arranged at two ends of the barrel body through curling, film-covered layers are attached to the front and back surfaces of the barrel body and the end covers 5, and heating mechanisms for heating the two end covers 5 are arranged at two axial sides of the barrel body; the heating mechanism comprises a heating part and a driving piece for driving the heating part to axially move along the barrel body 4, and the heating part is a high-frequency heating pipe or an electric heating pipe; in the embodiment, the heating part is a high-frequency heating pipe 2, and the driving part is a cylinder 3; the plates of the barrel body and the end cover 5 are metal plates, and the thickness of the metal plates is 0.6 mm-1.2 mm; the thickness of the film layer 1 on the back surfaces of the two end covers 5 is 0.06-0.1 mm, the thickness of the film layer 1 on the back surfaces of the two end covers 5 is thickened, and the arrangement is that the film layer on the adjacent barrel body 4 at the curled edge and the film layer on the end covers 5 can be fused better, so that good sealing of the two ends of the barrel body 4 is realized.
