Abstract
The utility model relates to a novel drawing frame pressure bar device. The novel drawing frame pressure bar device comprises a pressure bar (1) and pressurizing and positioning arms (2), wherein the cross section of the pressure bar (1) is in the shape of a water drop streamline; a boss (11) is arranged at one end of the pressure bar (1); the pressurizing and positioning arms (2) are provided with pressurizing and positioning surfaces (21), rotating holes (22), installment holes (23) and a clamping groove (24); the two ends of the pressure bar (1) are installed in the installment holes (23) of the pressurizing and positioning arms (2); the boss (11) is inserted into the clamping groove (24); shaft sleeves at the two ends of a drafting belt roller are sleeved with the pressurizing and positioning arms (2) through the rotating holes (22). The novel drawing frame pressure bar device has the advantages of being simple in structure, practical, and capable of being used for conveniently setting a machine going and generating bars and reducing friction force in the drafting process, and improving yarn evenness of finished yarn bars.
Description
Technical field
The utility model relates to a kind of drawing frame, is specifically related to a kind of novel pressure bar device of drawing frame.
Background technology
Drawing frame is the Spining Robot that the ribbon after some combings or the combing is processed into the ribbon with certain quality requirements.The effect of drawing frame is the internal structure of improving strip, thereby improves its uniformity, reduces simultaneously weight unevenness, make the straightening of fibers in the strip parallel, reduce crotch, make fineness up to specification, the raw material of variety classes or different qualities is mixed, reach the mixing ratio of regulation.
Present pressure bar device of drawing frame is because of the design defect of pressurization and location, and the carded sliver that is unfavorable for driving operates, and in drafting process, frictional force is larger, is unfavorable for the bar evenness of slivering.
Summary of the invention
The purpose of this utility model is to provide a kind of novel pressure bar device of drawing frame, and is simple and practical, uses can conveniently the drive carded sliver operation of this device, can reduce the frictional force in the drafting process, improves the bar evenness of slivering.
The technical solution adopted in the utility model is: a kind of novel pressure bar device of drawing frame, comprise pressure bar 1 and pressurization registration arm 2, the cross section of pressure bar 1 is the water droplet streamlined, one end of pressure bar 1 is provided with boss 11, be provided with pressurization locating surface 21, rotating hole 22, installing hole 23 and draw-in groove 24 on the pressurization registration arm 2, the two ends of pressure bar 1 are installed in the installing hole 23 of pressurization registration arm 2, boss 11 is inserted in the draw-in groove 24, and pressurization registration arm 2 is sleeved on the axle sleeve at drawing-off roller two ends by rotating hole 22.
Described pressurization locating surface 21 has the α angle with the line of centres of rotating hole 22 and installing hole 23, and the α angle is between 5 °～90 °.
The utility model compared with prior art has following beneficial effect: simple and practical, use can conveniently the drive carded sliver operation of this device, and can reduce the frictional force in the drafting process, improve the bar evenness of slivering.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of pressurization registration arm 2;
Fig. 3 is the cross-sectional view of pressure bar 1.
The specific embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of novel pressure bar device of drawing frame, this device comprises pressure bar 1 and pressurization registration arm 2, the cross section of pressure bar 1 is the water droplet streamlined, one end of pressure bar 1 is provided with boss 11, be provided with pressurization locating surface 21 on the pressurization registration arm 2, rotating hole 22, installing hole 23 and draw-in groove 24, pressurization locating surface 21 has the α angle with the line of centres of rotating hole 22 and installing hole 23, the α angle is 45 °, the two ends of pressure bar 1 are installed in the installing hole 23 of pressurization registration arm 2, boss 11 is inserted in the draw-in groove 24, and pressurization registration arm 2 is sleeved on the axle sleeve at drawing-off roller two ends by rotating hole 22.
During the driving carded sliver, pressure bar can together lift with the drawing-off roller by the pressurization registration arm, make things convenient for carded sliver operation, during spinning, pressure bar is by the pressurization locating surface pressurization location of pressurization registration arm, and the water droplet streamlined cross section of pressure bar can reduce the frictional force in the drafting process, improves the bar evenness of slivering.
