Abstract
The invention relates to a strand throwing mechanism for production of a continuous glass fiber strand mat, which is characterized in that the strand throwing mechanism comprises an autorotating pulling wheel and a strand throwing wheel, wherein a plurality of gaps extending axially are distributed on the circumference surface of the pulling wheel uniformly; the strand throwing wheel is mounted in the pulling wheel; radial bulges capable of being embedded from the interior of the pulling wheel and stretching out of the gaps of the pulling wheel are formed on the external surface of the strand throwing wheel; and the strand throwing wheel can swing within a certain included angle along the inner arc surface of the pulling wheel. Strands pass through a stand guiding roll, then enter the strand throwing mechanism, and are wound on the partial circumference surface of the pulling wheel in a wrapping manner; the wrap angle of the pulling wheel is larger; the strand throwing wheel autorotates and swings within the certain included angle along the inner arc surface of the pulling wheel when the pulling wheel rotates; and when the strand throwing wheel is engaged with the pulling wheel, the glass fiber strands clung to the surface of the pulling wheel at an engaged part are separated and thrown onto a moving mesh belt below the strands by the action of a centrifugal force, cover the whole width of the mesh belt, and form a continuous strand mat.
Description
Technical field
The present invention relates to a kind of glass fibre continuous strand felt production throwing machine structure, particularly a kind of silk of throwing is effective and consume energy glass fibre continuous strand felt production throwing machine structure low.
Background technology
Glass fibre continuous strand felt is that a kind of Novel glass fiber nonwoven strengthens base material, it is owing to having isotropism, leading good fluidity, resistance to erosion, cover that mould is good, mechanical strength is high, easily discharge the advantages such as bubble, be widely used in the forming process of glass fiber reinforced plastics such as pultrusion, mold pressing, winding, hand paste, vacuum forming, the article of fiber reinforced plastics that strengthens with this base material is widely used in the fields such as space flight and aviation, chemical anticorrosion, automobile, ships and light boats, completion, sports equipment, building materials, electronics, electrical equipment, amusement appliance.
At present China's glass fibre continuous felt is glass fibre to be laid on form the felt base on the guipure when the production moulding, sprays upper binding agent or emulsion again, cut edge after drying, the cooling, rolling continuous felt.Glass fibre is when forming the felt base of guipure width, traditional method adopts shock plate method and conveyor belt method, the shock plate method is also named and is moved oven process, it is a kind of older molding mode, the glass fibre that is got off by bushing is through being shed glass fiber on the guipure of operation by yarn-throwing apparatus behind baster, the buncher, and yarn-throwing apparatus ceaselessly moves back and forth back and forth along vertical web tape running direction, is paved into the uniform felt base of thickness, fiber drawing furnace need move around, and it is high that whole equipment moves back and forth power consumption.Conveyor belt method is that fiber drawing furnace is motionless, only yarn-throwing apparatus motion, and shortcoming is: back and forth can make fibre diameter produce fluctuation in the process.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of glass fibre continuous strand felt production throwing machine structure that silk is effective and consume energy low of throwing.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of glass fibre continuous strand felt production throwing machine structure, its innovative point is: but comprise drawing wheel and throwing the silk wheel of rotation, described drawing on the wheel periphery is evenly distributed with some axially extended slits, throwing silk wheel is installed in and draws in the wheel, throwing silk wheel outer surface is provided with can be from drawing wheel to be embedded in and stretching out the radial pattern projection of drawing the wheel slit, and described throwing silk wheel can be along drawing the wheel intrados to do the swing of certain angle.
Further, described wheel and the throwing silk wheel of drawing waits the linear speed motion by mechanical traditional structure connection.
Further, the described silk wheel of throwing is by wheel is inner realizes throwing the silk wheel with respect to the oscillating traverse motion of drawing wheel to draw planetary structure centered by the wheel center of circle to be installed in to draw.
The invention has the advantages that: precursor enters the throwing machine structure through behind the godet roller, surround on the part circumferential surface that draws wheel, its cornerite is larger, draws wheel to rotate the while, throws silk wheel rotation and edge and draws the wheel intrados to do the swing of certain angle, after throwing the silk wheel and drawing the wheel engagement, break away from so that the glass fiber precursor that draws wheel surface is close at this place, and under centrifugal action, the precursor throwing below on the mobile guipure, cover whole guipure width, form the continuous strand felt.
Description of drawings
Fig. 1 is glass fibre continuous strand felt production of the present invention throwing machine structure front view.
Fig. 2 is glass fibre continuous strand felt production of the present invention throwing machine structure side view.
The specific embodiment
As shown in Figure 1, 2, but comprise drawing wheel 1 and throwing silk wheel 2 of rotation, drawing wheel 1 periphery to be evenly distributed with some slits 3, this slit 3 is along drawing wheel 1 periphery to extend axially, throwing silk wheel 2 is installed in and draws in the wheel 1, form a similar internal gear pair structure with drawing wheel 1, throwing silk wheel 2 outer surfaces are provided with can be from drawing wheel 1 to be embedded in and stretching out the radial pattern projection 4 of drawing wheel 1 slit, and throwing silk wheel 2 can be along drawing wheel 1 intrados to do the swing of certain angle.
Draw wheel 1 and throwing silk wheel 2 to connect by mechanical traditional structure and wait the linear speed motion.Concrete, throw silk wheel 2 by wheel 1 is inner realizes throwing silk wheel 2 with respect to the oscillating traverse motion of drawing wheel 1 to draw planetary structure centered by wheel 1 center of circle to be installed in to draw.
Operation principle: precursor enters the throwing machine structure through behind the godet roller, surround on the part circumferential surface that draws wheel 1, its cornerite is larger, draws wheel 1 to rotate the while, throws silk wheel 2 rotations and edge and draws wheel 1 intrados to do the swing of certain angle, when throw silk wheel 2 with draw wheel 1 engagement after, draw the glass fiber precursor on wheel 1 surface to break away from so that this place is close to, and under centrifugal action, the precursor throwing below on the mobile guipure, cover whole guipure width, form the continuous strand felt.
