Internal profile production line

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.

Description

technical field [0001] The invention relates to a spacer profile production line. Background technique [0002] At present, most of the commercially available spacer profiles adopt the profile style produced by Technoform, and its production equipment can be found in the patent 201711195732.0-a warm edge spacer production line, which includes a feeding area and a processing area, which was applied by Akfa in 2017. The feeding area includes a base, and the top of the base is provided with a heat-insulating bar rack and a metal sheet rack, and a disc-shaped heat-insulating bar and a disc-shaped metal sheet are respectively erected on the heat-insulating bar rack and the metal sheet rack. The processing area includes the frame, gluing area, roll forming area, assembly area, cooling area and cutting area, and the gluing area, roll forming area, assembly area, cooling area and cutting area are all set on the frame; the gluing area The area includes a hot-melt glue machine, a glu...

Problems solved by technology

[0003] However, because the bonding medium between the heat insulation strip and the metal frame is butyl rubber during processing, and butyl rubber is in the heating channel of the production line, if the channel is too long, the bonding strength on the two wings of the metal frame will decrease. When the channel is too short, the melting effect of butyl rubber is not good, and the metal frame and the heat insulation strip will be evenly bonded, which leads to a higher requirement for the length of the heating channel in this production line. As we all know, because the equipment is in In the workshop at room temperature, due to seasonal and climate changes, no matter how accurate the length of the heating channel is set, there will also be problems of being too long or too short, resulting in the substandard bonding strength between the heat insulating strip and the metal frame.
