Abstract
The utility model discloses a drawing roller for cotton spinning. The drawing roller comprises a roller seat, a roller optical axis and a leather ring pin. Three equidistant oblique tooth grooves are arranged on the roller optical axis mounted on the roller seat. The rotation direction of tooth forms of two adjacent oblique tooth grooves is opposite. A layer of chromium is electroplated on the surface of the roller optical axis. Two ends of the leather ring pin are connected to the roller seat through supporters. The clearance between the leather ring pin and the roller is 0.4+/-1.98mm. The drawing roller is simple in structure, a roller shaft is less prone to abrasion, wear resistance of the roller is increased by the electroplated chromium, a floating area is reduced, and fiber control is enhanced.
Description
Technical field
The utility model relates to technical field of textile machine, particularly relates to a kind of cotton spinning drawing rollers.
Background technology
Its hardness of drawing rollers that domestic existing cotton spinning is used is not high, not wear-resistant, and service life is short, and the drawing-off of roller is swum the district greatly, and the towing area longitudinal frictional force distributes also inhomogeneous, causes roller shaft to frequent wearing and tearing, relatively poor to fiber control, it is unusual that drawing-off easily occurs, and causes yarn quality to descend.
Summary of the invention
In order effectively to overcome the above problems, the utility model provides a kind of cotton spinning drawing rollers, and is simple in structure, is difficult for producing wearing and tearing, and ABRASION RESISTANCE is strong, and the control of fiber is good.
To achieve these goals, the technical solution adopted in the utility model is: a kind of cotton spinning drawing rollers, the optical axis, the apron pin that comprise roller stand, roller, equidistantly be provided with the helical teeth groove more than three or three on the described roller optical axis that is installed in roller stand, the profile of tooth direction of rotation of adjacent helical teeth groove is opposite, and roller optical axis surface electrical is coated with one deck chromium; Described apron pin two ends are connected on the roller stand by support member, and apron pin and roller gap are 0.4 ± 1.98mm.
Compared with prior art, the utility model has the advantage of: simple in structure, roller shaft is to being difficult for producing wearing and tearing, and electrodeposited chromium layers can strengthen its ABRASION RESISTANCE, and the district of swimming dwindles, and has strengthened the control to fiber.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model apron pin and supporting piece structure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Consult Fig. 1, Fig. 2, a kind of cotton spinning drawing rollers, the optical axis 2, the apron pin 4 that comprise roller stand 1, roller, equidistantly be provided with the helical teeth groove 3 more than three on the described roller optical axis 2 that is installed in roller stand 1, the profile of tooth direction of rotation of adjacent helical teeth groove 3 is opposite, and roller optical axis 2 surface electrical are coated with one deck chromium; Described apron pin 4 two ends are connected on the roller stand 1 by support member 5, and apron pin 4 is 1.98mm with the roller gap.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have change and change.All within spirit of the present utility model and principle, any modification of doing, improvement etc. all should be included within the protection domain of the present utility model.
