Double hard panel polyurethane composite insulation board production line

Abstract

The invention discloses a polyurethane composite thermal insulation board production line with double-hard panels, which includes a panel feeding mechanism, a panel conveying mechanism and a coating mechanism. The feeding mechanism includes an upper layer feeding mechanism and a lower layer feeding mechanism. The plate conveying mechanism includes an upper plate conveying mechanism and a lower plate conveying mechanism, the upper plate conveying mechanism and the lower plate conveying mechanism are respectively provided with a heating mechanism, and the upper plate conveying mechanism and the lower plate conveying mechanism are arranged at an angle less than 45° . It effectively solves the problem of difficult feeding of the upper and lower composite boards in the production process of the double-hard surface polyurethane composite insulation board, and realizes the continuous transfer operation of the boards, which greatly improves the production efficiency. At the same time, through the coating of polyurethane foam Preheating the board bridge before the material, effectively guarantees the reliability of the composite bonding of the boards, greatly improves the production quality of the double-hard polyurethane composite insulation board, and its quality is more stable.

Description

technical field [0001] The invention belongs to the technical field of a composite thermal insulation board production line, and in particular relates to a polyurethane composite thermal insulation board production line with double-hard panels. Background technique [0002] With the application of thermal insulation and energy-saving materials in the construction industry more and more widely, the double-hard panel polyurethane composite thermal insulation board has been greatly recognized by the market for its excellent performance. It has strong bending load resistance and good impact resistance. Good bonding performance, waterproof and fireproof. The market prospect is broad, but because the current continuous production line can only be suitable for hard-faced metal coils or single-sided plates, it is difficult to achieve effective continuous production for double-sided composite hard-faced plates, and its production efficiency is low, and it is difficult to meet market ...

AI Technical Summary

Problems solved by technology

Its disadvantages are: 1) The material of the layers is slow, and it is difficult to achieve continuous production; 2) It is easy to cause misalignment between the upper and lower layers, and manual operation is not easy to align neatly, labor-intensive, time-consuming, laborious, difficult to control quality, and high scrap rate , which greatly affects the overall performance and production cost of the panel

There is also the traditional manual molding method, but its production efficiency is extremely low, the cost is high, the quality is unstable, and it is more difficult to meet the market demand
