Description

Technical Field

[0001] The utility model relates to the field of compound machines, in particular to a high-efficiency energy-saving drying tunnel of a compound machine. Background Art

[0002] The glue on the laminating machine is usually dried before use. In the process of the laminating machine, the glue needs to be dried after coating to ensure that the glue can fully solidify and form a stable composite structure. The working principle of the dry laminating machine is to stick different plastic films together through a dry laminating process. After the glue is applied, the solvent in the glue is fully dried by heating and exhausting, and then the laminating is carried out in a "dry" state.

[0003] The heating and exhaust process needs to be completed through a drying channel. The structure of the existing drying channel includes a hot air blower and an oven. The oven has a drying channel. The composite material after glue coating passes through the drying channel. The hot air blower passes hot air into the oven and exhausts it from the air outlet of the oven. During continuous operation, the heating of the glue by the hot air will emit a pungent odor and pollute the surrounding environment. At the same time, the hot air discharged from the air outlet is equivalent to the intake air. These hot air require electricity consumption, so the energy consumption is very large, which also causes waste and is accompanied by pollution. Utility Model Content
