Problems solved by technology
[0002] At present, the compounding of decorative films on the visible surface of profiles in the domestic market is mainly laminating by laminating machines or spraying and printing on spraying printing machines, which are very unsatisfactory in terms of economy, firmness and aesthetics; it is necessary to increase the investment in laminating or printing equipment. After the profile is extruded, secondary processing is required off-line, which requires additional materials such as glue and paint and a large amount of artificial energy input, prolonging the product processing time and increasing costs, and spray printing will also cause environmental pollution and cause physical damage to workers , so these lamination processes currently used are far from being able to meet the needs of the market

Embodiment Construction
[0017] A method for manufacturing a decorative film co-extruded composite profile, comprising the following steps:
[0018] (1) First fix the decorative film on the top, bottom or both sides of the die;
[0019] (2) Use the conveying device synchronized with the tractor to convey the decorative film to the dedicated channel for the die head plane;
[0020] (3) Use the waste heat of the die to heat the decorative film. The melting temperature is 150°C-200°C. After the bottom film is melted, the decorative film is clad on the visible surface of the substrate at the exit of the die through a special coating device;
[0021] (4) The base material after coating enters the vacuum setting mold and the cooling setting mold for setting, and the decorative film is very firmly combined with the base material;
[0022] (5) The compounded profiles are sent to the cut-to-length cutting table by the synchronous tractor for cut-to-length cutting. A pollution-free and low-cost film-coated pr...

The invention relates to a method for producing a decorative film coextrusion compound profile, which comprises the following steps: (1) firstly fixing decorative films on the upper and lower parts or both sides of a die head; (2) utilizing a conveying device synchronous with a tractor to convey the decorative films to a channel special for the die head plane; (3) utilizing the waste heat of the die head to heat the decorative films, and cladding the decorative films on the visible sides of a substrate at the die head outlet by a film laminating device after the bottom film is melted; (4) arranging a laminated substrate in a vacuum stock mold and a cooling stock mold to carry out molding, and compounding the decorative films and the substrate very firmly; and (5) conveying the compounded profile to a sizing cutting station by the synchronous tractor to carry out sizing cutting. The decorative film coextrusion of the invention is produced and completed with the profile once in an extruding line, has simple process, avoids investment of the off-line laminating printing equipment, reduces the working hours, reduces production cost, and has better adhesive attraction.
