Description

Technical Field

[0001] The utility model relates to the technical field of laminating machines, in particular to a heatable feeding mechanism of a laminating machine. Background Art

[0002] During the production process of panels, some panels, such as mirror panels or paint panels, need to be covered with a protective film on one side due to special processing requirements to avoid damage to the panels during subsequent logistics. The existing laminating work is generally performed by a panel laminating machine.

[0003] A cold laminator is a non-heated laminating machine that operates at room temperature. It directly adheres the sticky film to the printed matter by applying pressure. This type of machine is cheap and widely used in the sheet metal industry (aluminum plate, iron plate, plastic plate, wood plate, steel plate, glass plate, etc.), decoration industry, hardware industry, etc. Since the film used is sticky in itself, the cold laminator generally does not need to heat the film during its operation, so no heating mechanism such as a heating roller is set. However, in winter when the temperature is low, the low temperature will cause the viscosity of the film to decrease, seriously affecting the lamination quality. At this time, replacing equipment with a heating mechanism will lead to a significant increase in cost, so a heating mechanism that can be easily installed and disassembled is needed.
