Abstract

The utility model relates to a lateral blowing silk-floating preventing device of polyester staple fiber spinning production, which is characterized in that a wind screen is arranged in a crack between a machine frame of a spinning machine and a side frame of a lateral blowing device. The wind screen is a folded plate with a right angle, and the folded plate is connected with a sloping plate which is deviated outwards from a vertical line for 30 degrees. The lateral blowing silk-floating preventing device can eliminate tortuous flow formed by refraction of cooling wind air current, and intensifies the penetrability of cooling wind, thereby, nascent fiber on two ends can be operated downwards stably after the nascent fiber leaves a rectangular spinneret plate, and the nascent fiber can be neatly arranged. The lateral blowing silk-floating preventing device solves the chain problems that a drawing roller is coiled, broken filament of a feeder beater is twisted on a roller and the like due to silk floating, improves the operation rate of a spinning device, lowers the consumption of welding fluid, and also reduces the defects in post processing products of polyester staple fiber simultaneously.

Description

The anti-silk device that wafts of the lateral blowing of polyester staple fiber spinning production

Technical field

The utility model relates in lateral blowing anti-the waft silk device, the particularly crack between the frame of spinning machine frame and lateral blowing device of polyester staple fiber spinning production, is provided with the anti-silk device that wafts of deep bead.

Background technology

The main production process of polyester staple fiber is: measuring pump is quantitatively sent the polyester fondant under the molten condition into the rectangle filament spinning component, extrudes from the spinnerets micropore after assembly filters, and the side direction cooling air cooling after coagulation of process uniform temperature and temperature becomes as-spun fibre; As-spun fibre is through the barrel-shaped one-tenth precursor that oils, reels, falls, and after precursor reaches some, stretched again, typing, curls, cuts off, and promptly obtains polyester staple fiber.Carry-over pinch rolls and the feeding-wheel silk that wafts usually takes place in the polyester staple fiber technological operation twine car, the production efficiency of spinning before having influence on causes a large amount of waste silks, therefore often the waste silk rate as the key index of weighing device technique level and workshop management level height.It is because the silk that wafts causes mostly that carry-over pinch rolls and feeding-wheel twine car, the main cause that the silk that wafts produces is: after melt is extruded the formation as-spun fibre from spinneret orifice, the strand operation is extremely unstable when being subjected to the lateral blowing cooling, because the side-blown cooling air is behind vertical strainer filtering, air-flow is radial diffusion, become " fan-shaped " to blow out, the cooling air that blows out in lateral blowing device both sides, and thereby refraction formation sinuous flow takes place in the dividing plate collision back of spinning between the position, make the vibration aggravation of outboard end strand, so as-spun fibre about 10-15cm place after leaving spinneret orifice very easily causes the silk that wafts, wafing thread moves downward the formation fracture of wire, at the saddle type rotor, straight shape rotor, all may form lousiness on carry-over pinch rolls or the feeding-wheel, lousiness is poly-more many more, thereby causes twining car, does not twine car even if cause, these fracture of wires form overlength and fault in the processing of back, influence the finished fiber quality.

Summary of the invention

The purpose of this utility model is the anti-silk device that wafts of lateral blowing that a kind of polyester staple fiber spinning production will be provided, and in its crack between the frame of spinning machine frame and lateral blowing device, is provided with deep bead, reaches the effect of the anti-silk that wafts.

The anti-silk device that wafts of the lateral blowing of polyester staple fiber spinning production described in the utility model is characterized in that: in the crack between the frame of spinning machine frame and lateral blowing device, be provided with deep bead.

Deep bead described in the utility model is the flap connection one at a band right angle and the swash plates of outer inclined to one side 30 degree of vertical line.

The beneficial effects of the utility model are, it can eliminate the sinuous flow that the refraction of cooling air air-flow forms, strengthen the cooling air penetrability, thereby make as-spun fibre after leaving the rectangle spinnerets, the as-spun fibre at two ends operates steadily downwards, marshalling, each spins the silk that wafts of position and reduces to per 10 minutes less than 1 by 4～6 of per minutes, a phenomenon of wafing significantly reduces, solved because the silk that wafts causes linksystem problems such as coiling drawing roller and the curling round the roll of feeding-wheel lousiness, effect is very obvious, has improved the device for spinning running rate, reduce melt consumption, also reduced the fault in the converted products behind the polyester staple fiber simultaneously.

Description of drawings

Fig. 2 is a deep bead schematic diagram of the present utility model.

Among the figure: 1. charging aperture, 2. filament spinning component, 3. deep bead, 4. the lateral blowing device, 5. as-spun fibre, 6. finish oil disc, 7. descend oil tanker, 8. saddle type rotor, 9. straight shape rotor, 10. holder guide frame, 11. carry-over pinch rolls, 12. feeding-wheels, 13. precursor, 14. spinning machine frames.

The specific embodiment

The anti-silk device that wafts of the lateral blowing of polyester staple fiber spinning production described in the utility model as depicted in figs. 1 and 2, in the crack between the frame of spinning machine frame 14 and lateral blowing device 4, is provided with deep bead 3.Deep bead 3 is the flap connection one at a band right angle and the swash plates of outer inclined to one side 30 degree of vertical line.

Polyester staple fiber production master operation is as follows: melt enters filament spinning component 2 from charging aperture 1, extrude the spinnerets micropore in filament spinning component 2 then, under the lateral blowing cooling curing effect that lateral blowing device 4 blows out, form as-spun fibre 5, oil through finish oil disc 6 and following oil tanker 7 again, form polyester staple fiber precursor 13 through saddle type rotor 8, straight shape rotor 9, holder guide frame 10, carry-over pinch rolls 11 and feeding-wheel 12 successively, after precursor 13 is deposited certain hour, stretched again, typing, curl, cut off, obtain the polyester staple fiber product.

30,000 tons of/year polyester staple fiber process unitss use rectangle filament spinning component 2 and lateral blowing device 4, spinnerets in the filament spinning component 2, its hole count is up to 4150 holes, every capable hole count as many as 320 holes, after 4 filtrations of side-blown cooling air process lateral blowing device, the rectification, air-flow is radial diffusion, becomes " fan-shaped " to blow out, in order fully to cool off tow, the lateral blowing wind speed reaches 2.8-3.0m/s.But the cooling air that blows out in lateral blowing device 4 both sides, and the dividing plate that spins between the position bumps, and air-flow reflects, thereby forms sinuous flow, makes as-spun fibre 5 outboard end strands vibration aggravation, very easily causes the silk that wafts.

The utility model material therefor is a thin aluminum top, thickness is 1mm, thin aluminum top is cut into one that is of a size of 250mm (length) * 150mm (wide), it is processed as deep bead 3, as shown in Figure 2, wherein the flap height with the right angle is 20mm, base length is 30mm, connection one and the outer inclined to one side 30 long 200mm of swash plate that spend of vertical line, the right and left respectively has a slit between the frame of spinning machine frame 14 and lateral blowing device 4, stitches about wide about 1-1.5mm, leaves the place of spinning pack 2 near as-spun fibre 5 in this slit, each inserts a slice deep bead 3, as Fig. 1.The utility model can be eliminated the sinuous flow that the refraction of cooling air air-flow forms, and strengthens the cooling air penetrability, thereby makes as-spun fibre after leaving the rectangle spinnerets, and the as-spun fibre at two ends operates steadily downwards, and marshalling reduces a phenomenon of wafing.
