Abstract
The utility model relates to a roller for a magnetic compact spin, which comprises an optical shaft, a skewed tooth portion or a straight tooth portion arranged between the optical shaft at intervals, a guide hole and a guide pillar, wherein the shaft diameter of the skewed tooth portion or the straight tooth portion is equal to the shaft diameter of the optical shaft. The utility model makes diameters of the working surface and non-working surface of roller equal, not only having the advantages of convenience to machine and high availability ratio of material, but also diminishing the stress made by changing the diameter of non-working surface and gear-part working surface, thereby promoting the transverse strength of roller.
Description
Technical field
The utility model relates to a kind of roller of textile machine, especially relates to a kind of roller that magnetic is closely spun that is used for.
Background technology
Common roller is by the optical axis of non-working surface and be disposed on the helical teeth part of working face between the optical axis or straight-tooth part and guide hole and guide pillar constitute, every roller is typically provided with four, six or eight helical teeth or straight-tooth working face, be rove four ingot rollers, spun yarn six ingot rollers or spun yarn eight ingot rollers etc., the diameter of the working face of the every every ingot of roller is identical, but working face is different with the non-working surface diameter, in use often after being under pressure, Yin Luola has bending and influences spinning effect.In addition because the hand of spiral of distribution straight-tooth or helical teeth is symmetrically distributed in twos on every roller, spiral angle equates, when fiber was twisted by roller and roller, the motion of fiber disperseed, because fibre bundle does not gather, and causing bar stem organization state loose, the ribbon dry strength is low.For solving the problem that fibre bundle is loose and intensity is low, can adopt compact spinning at present, the set district is set in the draw zone downstream of drafting system, this set district is that the jaw line with outlet side is the border, when ribbon is distinguished by set, under the effect of air intake device, twist boundling, filoplume even collecting ribbon under the wind-force effect that ribbon is done, resultant yarn is even, and improves the intensity that ribbon is done.But the air intake device power consumption is many, causes the compact spinning apparatus cost higher, and complex structure, and cleaning is safeguarded cumbersome.
Summary of the invention
The purpose of this utility model provides a kind of roller that magnetic is closely spun that is used for that can improve machining accuracy and anti-bending strength.
The utility model for the technical scheme that achieves the above object is: a kind ofly be used for the roller that magnetic is closely spun, comprise optical axis, be disposed on helical teeth part or straight-tooth part and guide hole and guide pillar between the optical axis, it is characterized in that: the diameter of axle of described helical teeth part or straight-tooth part is identical with the diameter of axle of optical axis.
The utility model is owing to working face and the non-working surface with roller is same diameter, not only easy to process, the stock utilization height, and once mill processing, improve the machining accuracy of roller, and reduce the tooth portion reducing of the optical axis of non-working surface and working face and the stress that produces, can improve the bending strength of roller greatly, the assurance roller is not steadily walked about in operation process, has improved yarn quality.So when the magnet of magnetic tightening device is pressed on the roller of the present utility model, because the working face and the non-working surface of roller are isometrical, can make the complete and roller compact applying of magnet, between magnetic tightening device and the roller because of there not being the space, can form the negative pressure chamber of a complete closed with roller, make yarn in drafting process, form mandatory boundling simultaneously by the yarn guiding port on the magnetic tightening device, reach the reduction Yarn filoplume, improve the purpose of ribbon dry mass, can be widely used in and spin cotton textiles, cotton and synthetic fiber blending, isozygoty into fiber yarn etc.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a laura structure schematic diagram of the present utility model.
Fig. 2 is roller of the present utility model and front leather roller, the structural representation when drawing yarn roller and the assembling of magnetic tightening device.
Wherein: the 1-roller, the 11-guide hole, the 12-optical axis, 13-helical teeth part, the 14-guide pillar, 2-front leather roller, 3-draw the yarn roller, 4-magnetic tightening device.
The specific embodiment
See shown in Figure 1, the utility model is used for the roller that magnetic is closely spun, comprise optical axis 12, be disposed on the guide pillar 14 of helical teeth part 13 between the optical axis 12 or straight-tooth part and guide hole 11, roller one end is provided with guide hole 11, be provided with screw thread in the guide hole 11, and another distolateral guide pillar 14 is provided with screw thread, each roller can be spun and interconnect.See shown in Figure 1, the diameter of axle D1 of roller 1 helical teeth part 13 of the present utility model or straight-tooth part is identical with the diameter of axle D2 of optical axis 12, and the length of optical axis 12 is greater than the length of helical teeth part 13 or straight-tooth part, the length L of whole roller can be between 300～700mm, and the teeth groove of helical teeth part 13 or straight-tooth portion is trapezoidal teeth groove or garden arc teeth groove.See shown in Figure 1ly, the teeth groove helixangle of roller 1 its helical teeth part 13 of the present utility model is between-6 °～6 °.
See shown in Figure 2, roller of the present utility model 1 rolls 2 with preceding skin, draw yarn skin rod 3 and magnetic tightening device 4 when being used, magnetic tightening device 4 is close together with roller 1 surface under the effect of magnet, owing to do not have the space between magnetic tightening device 4 and the roller 1, formed the negative pressure chamber of a complete closed with roller 1, make yarn in drafting process, form mandatory boundling by the yarn guiding port on the magnetic tightening device 4 simultaneously, play the reduction Yarn filoplume, improve the purpose of ribbon dry mass.
