Abstract
The invention relates to an internal profile production line. The interval profile production line comprises an extrusion roller, a heat insulation strip conveying roller and a metal sheet roller, the heat insulation strip conveying roller and the metal sheet roller are arranged on the upstream of the extrusion roller, a heating channel, a cooling channel, a straightening device and a slitting device are sequentially arranged on the downstream of the extrusion roller, and a fixing frame located on the heat insulation strip conveying roller and the metal sheet roller is further arranged on the upstream of the extrusion roller. A linear core mold is hinged to the fixing frame, the linear core mold sequentially penetrates through the heating channel, the cooling channel and the straightening device after winding around the extrusion position of the extrusion roller and is in lap joint with a workbench of the slitting device, and the tail end of the core mold is located on the upstream of the slitting position of the workbench. By means of the characteristic that the core mold is located in a cavity defined by a metal sheet and a heat insulation strip all the time, continuous heating is kept in the heating channel, lasting cooling is kept in the cooling channel, and therefore the bonding strength between the heat insulation strip and a metal frame is improved.
