In dustproof coaxial combination roller, the roller axle sleeve of the fixing roller in left side or right side, axle sleeve external diameter is not of uniform size causes for it, forms the step that hinders flyings, fiber and enter dust ring.
In dustproof coaxial combination roller, fix roller and equate with the work outside diameter of kink roller, work outer round surface is processed with valley gutter, or is processed with straight flute, or is processed with annular knurl.
In dustproof coaxial combination roller, the external diameter of combined roller is 42～55mm.
In dustproof coaxial combination roller, the diameter of roller shaft is 20～25mm.
In dustproof coaxial combination roller, ball bearing is single-row ball bearing or single-row roller bearing or double row ball bearing.
The beneficial effect that the utility model is realized:
A kind of dustproof coaxial combination roller of the utility model, dustproof, the anti-greasy dirt structure of combined roller in structural design, are considered emphatically, ball or roller bearing transmission have been adopted simultaneously, suitably strengthen roller diameter, to improve the structure of combined roller, increase the service life, improve frictional drive power circle between roller and apron.
Brief description of the drawings
Fig. 1 is the structural representation of the basic assembled unit embodiment of a kind of dustproof coaxial combination roller of the utility model.
Detailed description of the invention
Below describe the technical solution of the utility model in detail.The utility model embodiment is only for explanation concrete grammar, and its scale of the method is not subject to the restriction of embodiment.
Embodiment
As shown in Figure 1, a kind of dustproof coaxial combination roller of the utility model, in the most basic assembled unit, include roller shaft (1), the fixing roller (21) in left side, roller (22) is fixed on right side, kink roller (3), ball bearing (4), dust ring (5), flat key (6), holding screw (7), the fixing kink roller of roller therebetween of the fixing roller in left side and right side is a pair of roller combination, the combination of a pair of roller corresponding two spindles on fine spining machine, on the roller shaft of each unit, have at least and be set with two pairs of roller combinations, kink roller (3) is transferred on roller shaft (1) by ball bearing (4), between fixing roller and kink roller, dust ring (5) is housed, dust ring is set on fixing roller and kink roller, roller is fixed on dust ring axis hole and left side or right side, the diameter difference that roller shaft coordinates, by the variation of axle journal size in structure, form the seal clearance of step, play prevention flyings, fiber enters bearing.
In dustproof coaxial combination roller, the cylindrical of dust ring (5) forms zero-clearance with the endoporus of kink roller (3) and coordinates, the axis hole of dust ring (5) and the sleeve outer circle of fixing roller, roller shaft form matched in clearance, dust ring has covered the seam of fixing roller and kink roller, the bulk fibre embedding gap between two rollers, by slide to the axle sleeve of fixing roller from the inclined-plane of dust ring, has also prevented that the lubricating oil in bearing from oozing to surface of roller.
In dustproof coaxial combination roller, the axis hole of dust ring matches with sleeve outer circle and the roller shaft of roller respectively, the journal size of sleeve outer circle and roller shaft is different, and the shaft hole diameter size of associated dust ring is also different, and the axis hole of different-diameter is concentric circular hole.
In dustproof coaxial combination roller, the fixing roller of the fixing roller in left side and right side, its structure is all single piece that are made up of roller circle (211,221), roller axle sleeve (212,222), spoke (213,223) three parts, on spoke, there is the through hole that connects left and right two ends, time convenient for cleaning, in the situation that not dismantling, remove the fiber of fixing outside roller axle sleeve with crochet hook.
In dustproof coaxial combination roller, the roller axle sleeve of the fixing roller in left side or right side, axle sleeve external diameter is not of uniform size causes for it, the diameter of axle matching with dust ring is larger, the seal clearance that fixing roller and dust ring form and the sleeve outer circle of fixing roller be not on the same face, and formation obstruction flyings, fiber enter the step of dust ring.
In dustproof coaxial combination roller, fix roller and equate with the work outside diameter of kink roller, work outer round surface is processed with valley gutter, or is processed with straight flute, or being processed with annular knurl, its different surface structure depends on its smooth roll drawing-off or apron draft for drafter.
