Problems solved by technology

However, the plastic layer part in the existing plastic sheet, especially the plastic in the middle layer part, has not been reinforced by inorganic or fiber, and belongs to the flexible material with low elastic modulus and low moment of inertia material. And under the joint effect of thermal expansion force, the compressive strength of pure plastic material in the existing plastic sheet cross-section structure is not enough, and the tensile strength of the plastic sheet reinforced by the two-sided glass fiber mesh cloth in the second middle layer is not enough, and its cross-sectional structure is under external pressure. Under the action, it is easy to produce deformation, and then cause the plate to bend, warp, shrink, elongate and other deformation phenomena, which cannot meet the use requirements of building formwork, building wall panels, vehicle and ship panels, furniture panels, etc.

Embodiment 2

[0091] A winding machine used for the production of thermoplastic prepreg reinforced pipes, including a prepreg heating winding machine and a tractor. The prepreg heating winding machine includes two types of forward rotation and reverse rotation, forward rotation and reverse rotation There are at least two each. All prepreg heating and winding machines are arranged to overlap each other with their central axes. The specific structure is:

[0092] The electric heater 4 uses a hair dryer, which is fixed at the lower half of the rotating disc 2 near the inner tube 100. Each hair dryer is fixedly connected with the conductive copper collar 12 with a cable, and the hot air blown by the hair dryer blows directly to The outer surface of the inner pipe 100 and the thermoplastic prepreg tape are wound at the junction. After the outer surface plastic of the inner pipe 100 and the thermoplastic prepreg tape are heated to a molten state at the same time, the molten prepreg tape is wound onto...

Description

Technical field [0001] The invention relates to the field of production equipment for plastic or plastic material pipes, in particular to a winding machine for the production of thermoplastic prepreg reinforced pipes and a method of use thereof. Background technique [0002] At present, plastic sheets are usually divided into single-layer, three-layer and five-layer. The single-layer sheet manufacturing equipment consists of a single screw extruder, a flat extrusion die, a set of three-roll calender, cooling setting machine, A production line composed of tractors, sheet trimming machines, sheet cutting machines and other devices. The single-layer plastic sheet produced by this equipment is structurally free of grid fiber reinforcement. The three-layer plastic sheet production equipment is extruded by a single screw Machine and two flat extrusion dies or two single-screw extruders and two flat extrusion dies, a single-layer fiber unwinding device, a set of three-roll calender, coo...
