Abstract
The utility model discloses a pneumatic sleeve roller machine functional head, comprising an adjusting sleeve, a guiding rod and a spring, wherein a screwed hole is formed in the internal upper part of the adjusting sleeve; a spring hole site is formed in the top of the guiding rod; the guiding rod is nested from the screwed hole at the upper end of the adjusting sleeve; the spring is arranged in the spring hole site; and the adjusting sleeve, the guiding rod and the spring are connected with a piston rod upper component of a pneumatic sleeve roller machine by the screwed hole on the adjusting sleeve. The innovation point of the pneumatic sleeve roller machine functional head is that a guiding hole is also formed in the internal lower part of the adjusting sleeve, a guiding mechanism is formed by the guiding hole and the guiding rod; the diameter of the guiding hole is smaller than the diameter of the screwed hole; and the upper edge of the guiding hole axially limits the guiding rod. The pneumatic sleeve roller machine functional head is simple in structure; when the adjusting sleeve moves relative to the guiding rod, a relatively high vertical coaxiality is provided, so that a vertical and uniform pressure can be provided for a rubber hose, and negative effects of bevel edges and the like are not easy to cause when a rubber-covered roller is sleeved.
Description
Technical field
The utility model belongs to field of textile machinery, relates in particular to a kind of pneumatic cover roller machine functional head.
Background technology
Rubber roll is that one of cardiac component of part mechanism is led in spinning, in the spinning, drawing process, is undertaking fiber movement, is reducing floating fiber and do sth. in advance speed change and reduce effect such as thickness of yarn joint.Existing pneumatic cover roller machine functional head is owing to lack guide frame between regulating sleeve and the guide rod or guiding length is too short, can not guarantee the vertical axiality of regulating sleeve and guide rod, the easy deflection of guide rod, it will not be vertical and uniform power that regulating sleeve imposes on the rubber hose that is enclosed within on the guide head, hypotenuse will appear in the rubber roll rubber hose end face circumference of cover postpone, dynamic property when influencing the rubber roll running causes spinning products of low quality.
Summary of the invention
The utility model purpose is for solving the deficiencies in the prior art, and rubber hose end face circumference was smooth when a kind of cover roller was provided, and do not have the pneumatic cover roller machine functional head of hypotenuse.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of pneumatic cover roller machine functional head, comprise regulating sleeve, guide rod and spring, the regulating sleeve internal upper part is shaped on screwed hole, the guide rod upper top is shaped on the spring eye position, guide rod is inserted in from regulating sleeve upper end snail pit, spring is as in the described spring eye position, by the screwed hole on the regulating sleeve regulating sleeve, guide rod and spring are linked to each other with pneumatic cover roller machine piston rod upper-part, its innovative point is: the bottom also is provided with pilot hole in the described regulating sleeve, form guiding mechanism with described guide rod, described guiding aperture is less than described tapped bore; And the pilot hole upper edge is to the guide rod axial limiting.
Further, described guide rod is divided into three parts, and top section is slightly less than regulating sleeve internal thread path for diameter but greater than the cylinder of described regulating sleeve pilot hole diameter; End section is the cylinder guide section that play the guiding role; The centre is the cone transition portion.
Further, the external shape of described regulating sleeve is the hex nut type, and the hex nut two ends arrange cylinder boss; Also be shaped on escape on the pilot hole in the described regulating sleeve, slightly larger in diameter is in described tapped bore.
Further, the length of described regulating sleeve 〉=1/3 guide rod length.
Further, be matched in clearance between the pilot hole of described regulating sleeve and the guide section of guide rod, fit clearance is 0.8 ~ 1.2mm.
The utility model is simple in structure, at regulating sleeve long pilot hole is set, can guarantee the vertical concentricity of regulating sleeve and guide rod, thereby make pressure that regulating sleeve puts on rubber hose evenly with vertical, the phenomenon of hypotenuse will can not appear in the rubber roll rubber hose end face circumference that overlaps postpone.
Description of drawings
Fig. 1 is the utility model functional head overall structure schematic diagram.
Fig. 2 analyses and observe and vertical view for the utility model regulating sleeve.
Fig. 3 is the utility model guide rod schematic diagram.
The specific embodiment
Shown in Fig. 1,2 and 3: guide rod 2 is divided into three parts, and section 2b in top is that diameter is less than regulating sleeve internal thread aperture but greater than the cylinder in described regulating sleeve guiding aperture; End section is the cylinder guide section 2c that play the guiding role; The centre is cone transition portion 2d; Guide rod 2 is inserted in regulating sleeve 1 from regulating sleeve 1 upper end snail pit 1a, because of the diameter of guide rod top 2b greater than the regulating sleeve aperture of leading, the upper edge of regulating sleeve pilot hole 1b is spacing to guide rod 2, again spring 3 is placed in the spring eye position 2a of described guide rod 2, be connected with parts 4 on the pneumatic cover roller machine piston rod by the screwed hole 1a of described regulating sleeve again, form functional head.
The external shape of described regulating sleeve is set to the hex nut type, at the two ends of hex nut cylinder boss 1d, 1e is set, and is convenient to regulating sleeve 1 is tightened and dismantled; Pilot hole 1b top also is shaped on escape 1c in the described regulating sleeve, is convenient to process the regulating sleeve pilot hole 1b of bottom in the regulating sleeve.
The detailed process of cover roller is as follows:
The utility model is simple in structure, and what cover applied the rubber cushion rubber during roller is vertical and uniform pressure, and difficult generation hypotenuse, side cut phenomenon have improved the quality of rubber roll.
