Problems solved by technology

[0003] With the improvement of people's awareness of environmental protection, the use of green packaging film is also increasing. Film lamination is an essential step in packaging. The traction mechanism of the existing laminating machine cannot be used according to the thickness of the packaging film. Adjusting the height by itself leads to the phenomenon that multiple films are pulled out at the same time after changing the packaging film of different thickness, which reduces the quality of the packaging and causes waste of the film. Therefore, we propose a self-adjusting height according to the thickness of the film. Laminating device for green packaging film

Abstract

The invention relates to the technical field of green packaging films, and discloses a film covering device capable of automatically adjusting height for a green packaging film according to film thickness. The device comprises a traction wheel, wherein the traction wheel is internally provided with hydraulic cavities which are annularly formed, and the opposite sides of the hydraulic cavities are provided with oil return holes and oil inlet holes; ball plugs are rotatably connected into the oil return holes, an elastic air bag is welded between the front inner wall and the rear inner wall of the traction wheel, annularly arranged traction mechanisms are inserted into the outer portion of the traction wheel, and annularly arranged adjusting mechanisms are inserted into the inner side wall of the traction wheel. An upward extrusion force of the packaging film is applied to a control panel located on a lower portion, then the control panel located on the lower portion is driven to contract, when the control panel contracts, an extrusion plate is driven by a supporting spring to extrude an elastic oil bag, and hydraulic oil in the elastic oil bag enters a hydraulic cavity from an oil inlet hole under the action of pressure till the control panel does not continue to contract, and therefore, the height of the traction mechanism can be automatically adjusted according to the film thickness.

Description

technical field [0001] The invention relates to the technical field of green packaging films, in particular to a laminating device for green packaging films that can self-adjust height according to film thickness. Background technique [0002] Green packaging materials refer to the process of production, use, scrapping and recycling, which can save resources and energy, can be quickly and naturally degraded or reused after being discarded, will not destroy the ecological balance, and have a wide range of sources, low energy consumption, and are easy to use Recycled and recycled materials or material products with high recycling rates, common green packaging materials generally include degradable plastics and natural biomolecular materials. [0003] With the improvement of people's awareness of environmental protection, the use of green packaging film is also increasing. Film lamination is an essential step in packaging. The traction mechanism of the existing laminating machi...
