Embodiment Construction

[0007] see figure 1 , the technical process of the present invention comprises:

[0008] 1. Send the glass fiber raw material to the glass fiber cutting machine through the glass fiber conveying pipe, cut the glass fiber into a specified length, and spread it evenly on the non-woven fabric. The speed of the glass fiber cutting machine is input into the computer console through calculation, so that the length and capacity of the glass fiber can meet the specified requirements. The non-woven fabric is conveyed by a conveyor belt.

[0009] 2. By controlling the speed of the powder spreader and the vibrator, evenly sprinkle the specified capacity of hot melt adhesive powder (PE powder) on the non-woven fabric and glass fiber.

[0010] 3. Use an infrared preheater to preheat the non-woven fabric, glass fiber and hot-melt adhesive powder with infrared rays. The power of the infrared preheater is 0-100KW, which can be adjusted in the range of 0-100% according to the requirements o...

Abstract

The invention relates to a method for processing vehicle polyurethane plate, which includes the processes of: cutting glass fiber and evenly scattering the glass fiber on one surface of unwoven cloth in sequence, scattering hot melt adhesive powder, infrared pre-heating and rolling; the material for processing is conveyed by a conveyer belt among various processes; the method for processing the polyurethane plate is characterized in that: the glass fiver and the hot melting adhesive powder are continuously and evenly scattered on the other surface of the unwoven cloth in sequence and the infrared preheating is carried out after the process of infrared preheating and then the rolling process is conducted to hit the target of combining and forming the products in one go. The method for processing the polyurethane plate has the advantages that: the secondary combination and formation of the vehicle polyurethane plate are changed into one-time combination and formation, thus not only enhancing the production efficiency by one time but also enhancing and stabilizing the product quality.

Description

technical field [0001] The invention relates to a processing method for a polyurethane vehicle roof plate composed of PU, non-woven fabric, hot melt adhesive powder, glass fiber and hot melt adhesive film. Background technique [0002] At present, the method of processing polyurethane roof panels in China is single-sided composite: that is, the front side of the polyurethane roof panel is composited first, and then the reverse side is composited. Its disadvantage is that the production efficiency is low, and due to the step-by-step processing of both sides, it is difficult to ensure consistent overall performance, which affects product quality. Contents of the invention [0003] The purpose of the present invention is to provide a processing method for polyurethane roof panels, which realizes the purpose of two-sided composite molding of polyurethane roof panels, solves the problem of low production efficiency in the prior art, and is difficult to process due to the step-b...
