Description

Technical Field

[0001] The utility model relates to the technical field of covering devices, in particular to an automatic covering device for hemp fiberboard. Background Art

[0002] The automatic hemp fiberboard wrapping device is used to cover the surface of hemp fiberboard with a protective film or other packaging material. The device typically consists of a conveying system, a gluing mechanism, a wrapping mechanism, and a control system. During operation, the hemp fiberboard enters the device through the conveying system, is sprayed with glue or adhesive by the gluing mechanism, and finally passes through the wrapping mechanism, where the protective film or packaging material is applied to the surface of the hemp fiberboard. This device improves the appearance and protective properties of the hemp fiberboard, while also increasing production efficiency and saving labor costs.

[0003] When some existing automatic covering devices for hemp fiberboards are used, adhesive is usually applied directly to the hemp fiberboard, so that uneven application may occur during the application process. As a result, when the protective film or packaging material is covered, adhesive overflow may occur, resulting in the need to trim the hemp fiberboard later. Therefore, this problem needs to be solved. Utility Model Content
