Embodiment Construction
[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.
[0023] Example.
[0024] see Figure 1 to Figure 3 , the recycling method of strip-shaped scraps of thermoplastic composite materials in this embodiment includes the following steps: (1) winding strip-shaped scraps 2 into rolls through a winding device 7, and the width of scraps 2 is less than 10 cm; The leftover material 2 is placed on the constant tension unwinding device 3; (3) enter the extruder 1 through the side feeding system 4 of the extruder 1 to extrude the pellets; (4) the extruded pellets are passed through injection molding or molding, etc. The molding method produces the desired finished product.
[0025] The winding device 7 in the present embodiment comprises a body 71, a motor 72, a slide block 73...

Abstract
The invention relates to a recycling and reusing method for strip-shaped leftover materials of a thermoplastic composite material and belongs to the field of material recycling. The strip-shaped leftover materials are wound in a roll mode through a winding device and then enter an extruder through a constant tension unwinding device to be extruded, then material particles are extruded, and the material particles are subjected to moulding modes such as injection molding or mould pressing to manufacture needed finished products. Recycling and utilization can be effectively achieved, the cost is reduced, pollution to the environment is reduced, and the promotion effect for development of the continuous fiber reinforced thermoplastic resin composite material is achieved.
Description
technical field [0001] The invention relates to a method, in particular to a method for recycling strip-shaped scraps of thermoplastic composite materials, which belongs to the field of material recycling. Background technique [0002] In the production process of continuous fiber reinforced thermoplastic resin composite material sheets or fabrics, according to the product width specification requirements, the edge width needs to be trimmed, and a certain width of the strip-shaped sheet or fabric will be reduced on the left and right sides. If this kind of leftover material is discarded, it will pollute the environment and increase the cost of the product. [0003] The existing processing method is to crush such strip-shaped scraps first, and then directly mold the crushed materials into products or use them as an intermediate layer to fill continuous rolling pressed boards. This production method will cause the mechanical properties of the materials to be lower than those m...
