Abstract
The utility model relates to a lower leather apron rolling tension bracket for a drawing device of a ring spinning frame, aiming at solving the technical problems that the existing lower leather apron tension bracket has high motion resistance for a lower leather apron and is unstable in operation. The lower leather apron rolling tension bracket has the technical scheme that; the tension bracket comprises a tension bracket body which comprises a sliding sleeve, a threaded shaft, an end cover, an opening check ring and a nut, wherein the threaded shaft is molded with the tension bracket body by mould pressing, thus having the functions of connecting and centering; the sliding sleeve is arranged on the threaded shaft so as to form a rolling friction pair; the opening check ring is installed inside a check ring groove arranged on the threaded shaft and positioned on the end cover of the sliding sleeve; and the end cover is arranged at the side surfaces of the sliding sleeve and the opening check ring and is fixed on the threaded shaft by a nut. The lower leather apron rolling tension bracket has the advantages that the lower leather apron has low motion resistance and stable operation and can improve the yarn quality, the comprehensive economic benefit is good, and the like.
Description
Technical field
The utility model relates to a kind of drafting system of ring spinner apron rolling tension bracket down.
Background technology
At present, the most drawing-off forms that adopt the length apron of ring throstle proparea drawing-off.One end of the following apron tension bracket of this drawing-off form is provided with a fixed cover, the other end is provided with a sliding friction axle that is parallel to fixed cover, owing to be sliding friction between sliding friction axle and the following apron, the resistance of motion of following apron is big, make down the apron operation not steady, hindered the further raising of spun yarn yarn quality.
Summary of the invention
The purpose of this utility model is to solve the big and jiggly technological difficulties of operation of the following apron resistance of motion that existing apron tension bracket down exists, and provides the little and drafting system of ring spinner that operates steadily of a kind of apron resistance of motion down with apron rolling tension bracket down.
The utility model for the technical scheme that solves above-mentioned technological difficulties and adopt is: drafting system of ring spinner is with apron rolling tension bracket down, comprise the tension force support body, wherein: it also comprises sliding sleeve, thread spindle, end cap, split washer and nut, thread spindle through mold pressing with the moulding of tension force support body, make thread spindle play the effect that connects and feel relieved, sliding sleeve is contained in forms rolling friction pair on the thread spindle, split washer is contained in the circlip groove that is provided with on the thread spindle and is positioned at the end face of sliding sleeve, and end cap is located at the side of sliding sleeve and split washer and is fixed on the thread spindle through nut.
Because the utility model has adopted technique scheme, change sliding friction into rolling friction, reduced frictional resistance, make bar do the CV% value and improve 0.3%-0.5%, therefore, compare with background technology, it is little and operate steadily and can improve advantages such as yarn quality, overall economic efficiency are good to the utlity model has down the apron resistance of motion.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in drawings, drafting system of ring spinner in present embodiment apron rolling tension bracket down, comprise tension force support body 1, wherein: it also comprises sliding sleeve 2, thread spindle 3, end cap 4, split washer 5 and nut 6, one end of thread spindle 3 through mold pressing with 1 moulding of tension force support body, make thread spindle 3 one ends play the connection effect, the other end plays the effect of centering, sliding sleeve 2 is contained on the thread spindle 3 forms rolling friction pair, split washer 5 is contained in the circlip groove of thread spindle 3 other end settings and is positioned at the end face of sliding sleeve 2, and end cap 4 is located at the side of sliding sleeve 2 and split washer 5 and is fixed on the thread spindle 3 through nut 6.
