Description
Technical field
The utility model relates to the production equipment field for plastics or moulding material pipe, is specially for thermoplastic prepreg and strengthens the wrapping machine that tubing is produced.
Background technology
At present, plastic plate is divided into individual layer conventionally, three layers and five layers, individual layer sheet material manufacturing equipment is by a single screw extrusion machine, a flat mouth extrusion die, a set of three-roller calendar, cooling calibrator, hauling machine, plate trimming machine, the production line of the installation compositions such as sheet cutting machine, the monolayer plastic sheet material of this device fabrication, in structure, without latticed fiber reinforcement, three-layer plastic plate production equipment is by a single screw extrusion machine and two flat mouth extrusion dies or two single screw extrusion machines and two flat mouth extrusion dies, a single layer fibre unwinding device, a set of three-roller calendar, cooling calibrator, hauling machine, plate trimming machine, the production line of the installation compositions such as sheet cutting machine, the three-layer plastic sheet material of this device fabrication, the intermediate layer of structure is latticed fortifying fibre, upper and lower two-layer is plastics, because fibrage is placed in the middle position of sheet material section, when sheet material is subject to evenly load, do not have drawing-resistant function, but along with the stretching of plastics, produce deformation, do not have the effect of counter-bending distortion.
On market, five laminate material manufacturing equipments are by three extruders and three flat mouth extrusion dies or two single screw extrusion machines and three flat mouth extrusion dies, a double-deck fiber unwinding device, a set of three-roller calendar, four roller cooling calibrators, hauling machine, plate trimming machine and trimmer, the production line of the installation composition such as sheet cutting machine and trimmer, five layers of plastic plate of this device fabrication, from the center to being followed successively by central core outward, inferior middle level, intermediate layer, inferior skin and skin, wherein intermediate layer and upper and lower skin are all plastic layers, the inferior middle level of lower surface layer is all latticed fortifying fibre layer, this structure because of fiberglass mesh non-integral continuous, plastic plate after moulding is not had to the effect of enhancing, do not reach the requirement of template strength.
The inferior middle level that on market, the another kind of reinforcing material of five laminate material manufacturing equipments is upper and lower surface layer is all Chopped Strand Mat, have three-layer plastic and two-layer fiber, five layers of plastic plate is because fibrage is placed in the inferior middle level of the surface layer up and down of sheet material section, but this equipment can only keep in the utmost point short time, five layers of compound plastic plate of unshaped being rolled, plastics cannot be incorporated in glass carpet veneer, cannot form five layer materials and combine together, the requirement of the template strength of arriving.
What no matter sheet material was subject to is evenly load or load, and the fibrage of stress surface can play tension, counter-bending effect, greatly improves bending strength and the elastic modelling quantity of sheet material, has met the requirement of various uses sheet material to intensity and modulus.In actual applications, sheet material is as structure stress material (part), bearing the loads such as evenly load from plate face, load, play the similar effect of continuous beam, simply supported beam, Cantilever Beams, its section structure should play resistance to compression effect, play again the effect of tension, also will have the stable requirements such as linear expansion coefficient simultaneously.And plastic layer in existing plastic plate part especially the plastics of intermediate layer part do not pass through inorganic or fiber reinforcement, the flexible material that belongs to low elastic modulus and low the moment of inertia material, under the pressure producing under external force load action and pulling force and the acting in conjunction of heat expansion power, pure plastic material compression strength in existing plastic plate section structure is inadequate, the plastic plate tensile strength strengthening by two, time middle level glass fiber reticular cloth is inadequate, its section structure very easily produces deformation outside under pressure, then make sheet material bend, warpage, shrink, the metabolies such as elongation, cannot meet building template, building wall board, car and boat plate, the instructions for use of furniture panel etc.
