Description

Technical Field

[0001] The invention belongs to the technical field of composite board production, and in particular relates to a production line for lightweight composite wallboards. Background Art

[0002] Lightweight composite wall panels are a new type of building material that the country has encouraged and promoted in recent years. They have thermal insulation and sound insulation, light weight, fast construction speed, and cheap construction materials. They are widely used in the interior walls of civil buildings, kitchen partitions, bathroom partitions, office partitions, factory partitions, hotel interior walls and other fields.

[0003] In the production process of composite panels, the following problems exist: there is no overall optimization of the production line for rock wool and polyurethane double-layer composite panels. The existing production lines are mostly aimed at producing sandwich layers of a single material. As the advantages of this type of composite panel gradually become more prominent, the following defects are mainly improved in the production process: 1. In order to keep the production of the production line simple and improve production efficiency, it is urgent to rationalize the auxiliary feeding mechanism of the rock wool block. 2. Due to the unreasonable structural design, the slitting efficiency of the rock wool block is low, and dust pollution is prone to occur during the slitting process. In the process of composite board forming, the following problems exist: it is necessary to use glue spraying treatment on the inner side of the two outer steel plates, but the existing glue spraying equipment structure is not reasonable, the glue spraying gun cannot adjust the position arbitrarily, and the glue spraying effect is not uniform, resulting in the existing inner sandwich and outer steel plate The fit is not firm enough. In addition, the existing composite panel trimming machine has great difficulty in trimming operations, which affects work efficiency and trimming quality, and the trimming operation has a lot of dust in the working environment, which affects the health of the staff. In the production process of composite panels, when the steel plate is bonded to the internal interlayer, a complete sandwich panel will be formed. At this time, a cutting device is required to cut the sandwich panel into segmented insulation panels according to the length required by the customer. The band saw machine itself cannot be moved, which will limit production. Summary of the invention
