Abstract
The utility model relates to a device for preventing the turning over of cotton slivers during a conveying process. The utility model is composed of a sliver guiding device, a sliver guiding wheel, a table face, a feed roller and a traction mechanism, wherein the cotton sliver conveying direction which is composed of the sliver guiding device and the sliver guiding wheel is vertical with the cotton sliver conveying direction which is composed of the feed roller and the traction mechanism; the table face is arranged between the sliver guiding wheel and the feed roller; the table face is at least provided with a first sliver guiding nail and a second sliver guiding nail; the first sliver guiding nail is arranged in the cotton sliver conveying direction which is composed of the sliver guiding device and the sliver guiding wheel; the second sliver guiding nail is arranged in the cotton sliver conveying direction which is composed of the feed roller and the traction mechanism; when cotton slivers pass through the connecting line of shaft centers of the first sliver guiding nail and the second sliver guiding nail, the cotton slivers are crossed with the cotton sliver conveying direction which is composed of the sliver guiding device and the sliver guiding wheel and the cotton sliver conveying direction which is composed of the feed roller and the traction mechanism. When the cotton slivers are conveyed, the cotton slivers are gradually turned to 90 DEG along the first sliver guiding nail and the second sliver guiding nail, fiber tension at the inner side and the outer side is even, and thus, the phenomena of turning over and tortuosity after the cotton slivers pass through the sliver guiding nails are reduced.
Description
Technical field:
The utility model relates to textile machine, relates in particular to cotton textile machinery, the particularly feed mechanism of sliver, and concrete is that the device of upset takes place in course of conveying a kind of sliver that prevents.
Background technology:
In the prior art, the feeding frame of sliver lap machines, strip ribbon lap machine and ribbon lap machine adopts elevated structure in a large number, sliver feeds in the strip guide wheel of positive transmission after being drawn out of from the bar bucket and introducing bar-guiding device, and strip guide wheel is transported to sliver on overhead table top, sends into drafter by feeding roller and carries out drawing-off.Because strip guide wheel carries the direction of sliver to become an angle of 90 degrees with the direction that sliver enters on the feeding roller, so on table top, be vertically installed with a sliver nail, the sliver nail is positioned at strip guide wheel and carries the direction and the sliver of sliver to enter the intersection of the direction on the feeding roller, makes sliver turn to 90 degree operations at this.But, in the practical work process, flop phenomenon is constantly taking place through sliver nail back in sliver, entering drafter after the distortion on the table top, if the sliver of distortion feeding drawing frame will influence the drawing-off quality, if feeding strip ribbon lap machine or sliver lap machines, the quality of rouleau is descended, can cause fibre damage, short flannel and noil to increase during combing.
Summary of the invention:
Technical problem of the prior art to be solved in the utility model is: because in the prior art, in the feed mechanism of sliver, strip guide wheel carries the direction of sliver to become an angle of 90 degrees with the direction that sliver enters on the feeding roller, a vertically disposed sliver is followed closely the direction and the sliver that are positioned at strip guide wheel conveying sliver and is entered the intersection of the direction on the feeding roller on the table top, sliver turns to 90 degree operations at this, in the practical work process, flop phenomenon is constantly taking place through sliver nail back in sliver, entering drafter after the distortion on the table top, if the sliver of distortion feeding drawing frame, to influence the drawing-off quality, if feeding strip ribbon lap machine or sliver lap machines, the quality of rouleau is descended, can cause fibre damage during combing, short flannel and noil increase.
The utility model is that technical scheme that solution above-mentioned technical problem of the prior art is adopted provides a kind of sliver that prevents the device of upset takes place in course of conveying, the device of upset takes place by bar-guiding device in the described this sliver that prevents in course of conveying, strip guide wheel, table top, feeding roller and drafter constitute, described bar-guiding device and strip guide wheel are separately positioned in the frame, described feeding roller and drafter also are arranged in the support, the mutual alignment relation of described bar-guiding device and strip guide wheel and described feeding roller and drafter is fixing, bar-guiding device is vertical with the sliver throughput direction that drafter constitutes with feeding roller with the sliver throughput direction that strip guide wheel constitutes, described table top is arranged between described strip guide wheel and the feeding roller, wherein, on described table top, be provided with one first sliver nail and one second sliver nail at least, described first sliver nail is arranged in the sliver throughput direction of described bar-guiding device and strip guide wheel formation, described second sliver nail is arranged in the sliver throughput direction that described feeding roller and drafter constitute, and the sliver throughput direction that sliver throughput direction that constitutes with bar-guiding device and strip guide wheel simultaneously through the line in the axle center of first sliver nail and second sliver nail and feeding roller and drafter constitute is crossing.
Further again, follow closely and the line in the axle center that second sliver is followed closely and one first acute angle of sliver throughput direction formation of bar-guiding device and strip guide wheel formation through first sliver, follow closely and the line in the axle center that second sliver is followed closely and one second acute angle of sliver throughput direction formation of feeding roller and drafter formation through first sliver.
Further, the number of degrees sum of described first acute angle and second acute angle equals 90 degree.
Concrete, bar-guiding device described in the utility model, strip guide wheel, table top, feeding roller, drafter and sliver nail all adopt known technology of the prior art, about bar-guiding device, strip guide wheel, table top, feeding roller, drafter and sliver nail known solution in the prior art, those skilled in the art all knows, so do not repeat them here.
Operation principle of the present utility model is: turn to 90 degree gradually along first sliver nail and second sliver nail when sliver is carried, turn to the situation of 90 degree suddenly with respect to sliver in the prior art, tension force of outside fiber is more even in it, has therefore significantly reduced sliver in the phenomenon of overturning, twisting through sliver nail back.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is by being provided with second sliver nail, original sliver turned to the situations of 90 degree to change into suddenly to finish 90 degree gradually by the obtuse angle of continuous setting turn to, and can effectively reduce sliver in the phenomenon of overturning, twisting through sliver nail back.Simple in structure, use reliable.
Description of drawings:
Fig. 1 is the schematic diagram of drafting of sliver conveying mechanism of the prior art.
Fig. 2 is that the structural representation of the device of upset takes place in course of conveying a kind of sliver that prevents of the utility model.
The specific embodiment:
As shown in Figure 1, in the drafting of sliver conveying mechanism of the prior art, the feeding frame of sliver lap machines, strip ribbon lap machine adopts elevated structure in a large number, sliver 5 is extracted out from bar bucket 8 in the strip guide wheel 2 of introducing the positive transmission of bar-guiding device 1 back feeding, strip guide wheel 2 is sliver 5 defeated being placed on the overhead table top 3, send into drafter 7 by feeding roller 6 and carry out drawing-off, bar-guiding device 1 is vertical with the sliver throughput direction that drafter 7 constitutes with feeding roller 6 with the sliver throughput direction that strip guide wheel 2 constitutes, table top is provided with one first sliver nail 4, makes sliver turn to 90 ° of operations at this.
