Continuous Teflon press for thermoplastic composite material

Abstract

The invention discloses a continuous Teflon press for a thermoplastic composite material. The press includes a frame, a group of a driving roller and a tensioning roller which are arranged up and downand a Teflon conveying belt coating the driving roller and the tensioning roller are respectively arranged on the frame, a transmission device for driving the Teflon conveying belt to rotate is arranged between the driving roller and the tensioning roller, the transmission device is connected with the Teflon conveying belt through an elastic part, a heating area for heating a thermoplastic composite material and a cooling area for cooling the thermoplastic composite material are respectively arranged in the frame, and a thickness determining device for determining the thickness value of the thermoplastic composite material is arranged between the heating area and the cooling area.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a continuous Teflon press for thermoplastic composite materials. Background technique [0002] Both continuous fiber reinforced thermoplastic composites (CFRT) and glass fiber mat reinforced thermoplastic composites (GMT) have high strength, high rigidity and high toughness, and their performance is generally higher than that of short fiber reinforced thermoplastic composites (SFT). Structural parts and secondary load-bearing parts. As the automobile industry continues to require automobiles to reduce weight and reduce energy consumption, thermoplastic composite materials are widely used in bumper beams, instrument panel frames, engine covers, anti-stone impact covers, seat frames, battery brackets, car bottom guards, Various automotive parts such as wheel housings, luggage racks, and roof covers. In addition, due to the excellent performance of CFRT and GMT...

[0003] At present, the Chinese Patent Application Publication No. CN108340611A discloses a rolling flat press machine, which presses rubber and plastic materials through two pressing units, but this patent cannot effectively guarantee the thickness of rubber and plastic materials, etc., there is How to effectively request the thickness of rubber and plastic materials

[0004] In addition, there is currently a Chinese patent application publication number CN102529293A which discloses a double-steel-belt continuous press for the integrated production of composite plates with heating, cooling and shaping. The patent uses a driving roller and a driven roller to form upper and lower parts to press the slab. And transmission, there are also requirements that cannot effectively guarantee the thickness of the slab, etc., there is a problem of how to effectively require the thickness of the slab
