The invention relates to a broad-width multi-layer compound package material joint device and a method. A regulation screw nut (8) is sequentially connected with a knife body of a casting (1), a heat insulation pad (2), a heating block (3) and an aluminum block I heat sealing knife (4) from top to bottom, and is positioned at the upper part of the middle of the device, an aluminum block II heat sealing knife (7) is positioned right under the aluminum block I heat sealing knife (4), and is connected with a bottom fixed device, a Teflon high-temperature cloth (5) is covered outside the aluminum block I heat sealing knife (4) and is used as a heat insulation device, and the upper surface of the aluminum block II heat sealing knife (7) is provided with a silicon rubber high-temperature resistance strip (6) to be used as a heat insulation device. The method comprises the following process flows in sequence: unreeling new rolls of composite materials, lapping and overlapping new rolls of materials and old rolls of materials, clamping and fixing two layers of materials, heating a hot sealing knife and tightly clamping the hot sealing knife for hot sealing and releasing. The invention can solve the problem of the hot sealing of composite materials with large thickness in the prior art.
Description
technical field [0001] The invention belongs to the field of wrapping paper manufacturing, and in particular relates to a joint device and method for wide-width multi-layer composite packaging materials. Background technique [0002] Multi-layer composite packaging material is composed of cardboard, aluminum foil, and multi-layer plastic. It is characterized by a very thick thickness of 300-500mm and a width of 1.4m. It uses the general heat sealing technology-ultrasonic high frequency method It is difficult to achieve the effect of tight sealing joint. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wide-width multi-layer composite packaging material joint device and method, so as to solve the problem of heat-sealing composite materials with large thickness in the prior art. [0004] The technical scheme adopted by the present invention to solve its technical problems is: provide a kind of wide-width multi-la...
