However, 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 interlayer and outer steel plate not being firmly bonded. In addition, the composite board needs to be trimmed during production and processing to improve the sealing of the two composite boards after they are combined and reduce the difficulty of later assembly. The existing composite board trimming machine has low working efficiency and the trimming working environment is dusty, which affects the health of the staff.

The upper and lower steel plates are produced into the required shape under the action of the forming machine. The upper and lower steel plates move at a set speed under the action of the conveying mechanism. After the steel plates enter the glue spraying room, the lower steel plate is sprayed with rock wool special glue as needed. The rock wool equipment is carried out synchronously. The rock wool strips generated by the previous cutting, among which the rock wool strips located at one edge are driven by the clamping and conveying mechanism 1-4 and enter the cutting channel 1-2 of the trimming mechanism 1. After the rock wool strips are trimmed by the trimming mechanism 1, It moves forward under the drive of power, so that the rock wool strips fall onto the lower steel plate as needed, and then the feeding mechanism 3 sprays the foaming agent as needed to the rock wool falling on the steel plate, and then the upper and lower steel plates and the rock wool foaming agent below enter the crawler heating machine 5 together. The crawler heating machine 5 adopts electric heating, and moves forward at the set speed under the action of the side seals on both sides and the limiting and heating of the upper and lower crawler plates. When the plate comes out of the crawler heating machine 5, the rock wool and polyurethane double-layer composite board we need is formed, which is cut in sections by the band saw machine 4-3 on the cutting mechanism 4 to obtain the rock wool composite board of the required length.
