Detailed description of the invention
For making to have a better understanding and awareness architectural feature of the present invention and effect of reaching, coordinating detailed description in order to preferred embodiment and accompanying drawing, being described as follows:
As shown in Figure 1, a production unit for plastic flat fiber, comprises extrusion mechanism 61, T-shaped die head 62, cooling body 63, drier 64, divided mechanism, arc drawing-off drying-plate 65, drawing mechanism 66, arc sizing drying-plate 67, haulage gear 68, wire drawing mechanism 69.
Raw material through multiple physical condition effect, becomes molten condition in extrusion mechanism 61, after extruded to cool through cooling body 63 by T-shaped die head 62 and form diaphragm; Diaphragm is dissected by divided mechanism and is formed flat filament base after drier 64 drying; Flat filament base coordinates drawing mechanism 66 to stretch after the heating of arc drawing-off drying-plate 65; Flat filament base after secondary stretching, after arc sizing drying-plate 67 heat-shaping, is moved wire drawing mechanism 69 to by haulage gear 68 traction and is received silk.
Wherein, arc drawing-off drying-plate 65 is identical with arc sizing drying-plate 67 structure.As shown in Figure 2, heating arrangements comprises a box body; Fit upper cover is the curved surface be bent upwards; Box body comprises several drawers a, is provided with thermal source b in drawer a; The length of thermal source is equal to or greater than the width of diaphragm.Flat filament base is close to cartridge upper surface and is advanced, and the surface of curved surface makes flat filament base contact more abundant with box body upper cover.Thermal source b in drawer a starts after being energized to heat up, and because thermal source b does not contact with upper cover, institute thermal source b carries out divergence expression heating to upper cover, and upper cover is heated evenly.Flat filament base moves to the other end from heating arrangements upper cover one end, and heating path is long, so the temperature of each thermal source b should not make flat filament base rupture without the need to very high, suitable temperature, homogeneous heating, to make follow-up drawing effect better.
Certainly, according to the requirement difference making flat filament thickness, width, heating-up temperature can be adjusted in real time, such as can turn off wherein several thermal source b, to meet heating-up temperature requirement.
Thermal source can be the electrothermal tube often used in life.
As shown in fig. 3 to 7, divided mechanism, comprises blade 1, axle 2, spacer ring 3.The surface of axle 2 is provided with several holes 21 along axis.The center line line in several holes 21 and the axis being parallel of axle 2.Blade 1 is inserted in 21 li, hole, and spacer ring 3 this axle 2 sheathed is between adjacent two blades 1; The two ends of axle 2 are provided with fastening assembly; Fastening assembly is close to blade 1 is fixed on axle 2 by extruding between spacer ring 3 and blade 1.
According to the direction of transfer of plastic foil, the present invention is parallel with the radial section of axle 2 by the sidewall of blade 1.The degree of depth in hole 21 is 1/3 height of blade 1.The thickness of spacer ring 3 is 1/3 height of blade.That is, after blade 1 patchhole 21, and spacer ring 3 is set in after on axle 2, and the surface portion that blade 1 exposes spacer ring 3 accounts for 1/3 of blade 1 highly.Certainly, different according to blade material, rigidity is also different, so for the blade of different-stiffness, the degree of depth in hole and the thickness of spacer ring can adjust to some extent.
When blade 1 is with plastic foil effect, because blade 1 is thinner, the situation of rocking of easily vacillating now to the left, now to the right, the plastic wire base width cut out is uneven.In order to ensure the plastic wire quality cut out, blade 1 is designed to triangle or trapezoidal by the present invention, or other the shape with same function, its up-narrow and down-wide design, and the fixation of spacer ring 3 about it, blade 1 is not waved when stressed and rocks.
Plastic foil through divided mechanism, is the surface walking of being close to this spacer ring 3, and in order to not destroy plastic foil, the outer surface of spacer ring 3 provided by the invention forms a smooth surface.
Certainly, must fit tightly between spacer ring 3 and blade 1, just have the power that enough frictional force is subject to when chopping to offset blade 1.So the present invention arranges fastening assembly at the two ends of axle 2.Fastening assembly can be that one end of axle 2 is provided with the screw thread coordinated with clamp nut 4, and the other end is provided with baffle plate; Or the two ends of axle 2 are provided with the screw thread coordinated with clamp nut 4; By precession nut extruding spacer ring 3 and blade 1.
As shown in Figure 8, in order to increase the frictional force between spacer ring 3 and blade 1, spacer ring 3 provided by the invention is made for hard rubber material, and rubber itself has larger coefficient of friction.Or spacer ring 3 is made up of other hard materials, but at its sidewall, several rubber bumps 31 are set with increasing friction force.
As shown in Figure 9, the radial section of conventional clamp nut 4 is polygon, and be generally hexagon, clamp nut 4 provided by the invention is quadrangle, and the spanner matched with it is also quadrangle spanner 5.
In specific works, according to the difference of plastic wire base width requirement, select the spacer ring 3 of dimension, first blade 1 is inserted in 21 li, corresponding hole, spacing between adjacent two panels blade is met the requirements, spacer ring 3 is disposed between adjacent two panels blade 21 successively simultaneously.Then relatively screw extruding spacer ring 3 and blade 1 by the clamp nut 4 at axle 2 two ends, be fixed on axle to make blade 1.So far, a point silk device for plastic flat wire blank provided by the invention can be put in production.
Raw material is extruded to cool through cooling body 63 by T-shaped die head 62 and is formed diaphragm after extrusion mechanism 61 melting; Diaphragm is dissected by divided mechanism and is formed flat filament base after drier 64 drying; Flat filament base is stretched by drawing mechanism 66 after the heating of arc drawing-off drying-plate 65; Flat filament base after secondary stretching, after arc sizing drying-plate 67 heat-shaping, is drawn to wire drawing mechanism 69 by haulage gear 68 and receives silk.So far, Flat Yarn Production terminates.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and description; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain of application claims is defined by appending claims and equivalent thereof.
