Abstract
The invention discloses a pneumatic roller brake which comprises two under frames, wherein a brake hub is erected on the two under frames; a braking and clasping device is arranged below the brake hub; the braking and clasping device comprises flexible cylinders which are externally connected with gas pipes; rocker arms are fixedly connected with two ends of flexible cylinders; two fixing rods arranged right below the brake hub; two ends of each fixing rod are supported on the two under frames; the two fixing rods are parallel in the horizontal direction; connecting holes are formed in the middles of the rocker arms; the fixing rods penetrate through the connecting holes; the rocker arms are movably connected with brake claws through movable part connecting parts; a friction part is formed in one end of each brake claw. Compared with a magnetic powder brake, the braking effect of the brake is free from influence of moisture magnetic powder as the pneumatic brake mode is adopted, and the brake is simpler in structure, good in heat dispersion performance, long in service life and higher in braking efficiency.
Description
Technical field
The present invention relates to the equipment in a kind of papermaking, chemical industry, web-handled field, what be specifically related to is a kind of pneumatic roller brake.
Background technique
At present in papermaking, chemical industry, the normal operation electromagnetic brake is implemented material retractable control in the web-handled field, Chinese patent 97232319.8, a kind of electromagnetic powder brake is disclosed, this brake utilizes magnetic induction intensity and Magnetic flux density principle, control the operating voltage of brake so that the magnetic variable density of brake inside by control system, thereby make brake unit produce the purpose that different moment reaches start and stop, its deficiency is because this type brake applies to magnetic, and the structure of brake can not guarantee fully isolated with external environment, inner magnetic moisture-sensitive and braking effect is produced passive impact, and radiating effect is also not satisfactory in the airtight space.
Summary of the invention
The technical issues that need to address of the present invention are, provide that a kind of simple in structure, long service life, braking quality are high, the pneumatic roller brake of easy adjusting.
Technological scheme of the present invention is: a kind of pneumatic roller brake, comprise two underframe, two added brake hubs that are provided with of underframe, the brake hub below is provided with the braking enclasp device, described braking enclasp device comprises telescopic cylinder, telescopic cylinder is circumscribed with tracheae, the telescopic cylinder two ends are fixedly connected with rocking arm, be provided with two fixing rods under the brake hub, two fixing rod two end supports are on two underframe, two fixing rods are parallel in the horizontal direction; attachment hole is offered at rocking arm middle part, and described fixing rod interted attachment hole, and rocking arm is flexibly connected by active part joint and braking claw; braking claw one end is provided with friction part, described friction part and the mutual friction catch in brake hub surface.
In order to cooperate with roller better, strengthen braking effect, described braking claw is isosceles triangle, and friction part is located at the isosceles triangle bottom and is the indent arc, and the friction part radian is consistent with the circular arc degree of brake hub.
For larger moment is provided, described sub rocker arm is two-part up and down, up and down between two-part in obtuse angle, the upper end of part is provided with protuberance under the rocking arm, described attachment hole is located on the protuberance.
As preferably, described underframe and ground are screwed.
As preferably, every pneumatic roller brake is provided with two described braking enclasp devices, lays respectively at two ends of brake hub.
After adopting technique scheme, the present invention has following advantage:
Compare with magnetic powder brake, owing to adopting aerodynamic brake, do not worry that structure is comparatively simple because magnetic makes moist and braking effect is exerted an influence, perfect heat-dissipating, long service life, retardation efficiency are very high.
Description of drawings
Accompanying drawing 1 is looked schematic diagram for the master of the pneumatic roller brake of the present invention;
Accompanying drawing 2 is the side schematic view of the pneumatic roller brake of the present invention;
Accompanying drawing 3 is the schematic diagram of the braking enclasp device of the pneumatic roller brake of the present invention.
Shown in the figure, 1, underframe, 2, brake hub, 3, protuberance, 4, the braking enclasp device, 5, telescopic cylinder, 6, rocking arm, 7, the active connection part, 8, the braking claw, 9, friction part, 10, tracheae, 11, fixing rod.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
Such as Fig. 1, shown in Figure 2, the pneumatic roller brake of the present embodiment, comprise two underframe 1, two underframe 1 added brake hubs 2 that are provided with, brake hub 2 belows are provided with braking enclasp device 4, braking enclasp device (4) comprises telescopic cylinder 5, telescopic cylinder 5 is circumscribed with tracheae 10, telescopic cylinder 5 two ends are fixedly connected with rocking arm 6, be provided with two fixing rods 11 under the brake hub 2, two fixing rod two end supports are on two underframe, and two fixing rods 11 are parallel in the horizontal direction, and attachment hole is offered at rocking arm 6 middle parts, fixing rod 11 interted attachment hole; rocking arm 6 is flexibly connected by active part joint 7 and braking claw 8, and braking claw 8 one ends are provided with friction part 9, and described friction part 9 and brake hub 2 surfaces are friction catches mutually.
As shown in Figure 3, one end of the telescopic cylinder 5 in the braking enclasp device 4 is fixedly connected with rocking arm 6; rocking arm is two-part about in the of 6 minutes; form in obtuse angle up and down the bending shape of indent between two-part; the other end of rocking arm 6 links to each other with braking claw 8 by active connection part 7; friction part 9 is located at the isosceles triangle bottom and is the indent arc; friction part 9 radians are consistent with the circular arc degree of brake hub 2; protuberance 3 places of rocking arm 6 are provided with attachment hole; be interspersed with fixing rod 11 in the attachment hole; rocking arm 6 rotates around fixing rod 11, the formation lever.
Such as Fig. 1, Fig. 2, shown in Figure 3, when the spool gears of paper roll with after reduction gear in the pneumatic roller brake cooperates, by tracheae 11 air inlets, telescopic cylinder 5 expanses promote rocking arm 6 and rotate, and rocking arm 6 drives braking claw 8 transverse shiftings, along with the spacing of one group of braking claw 8 is dwindled gradually, thereby hold brake hub 2 tightly, slow down, thereby the rotating speed of paper roll is lowered.
Below only be described with regard to the better example of the present invention, but can not be interpreted as it is limitations on claims.The present invention not only limits to and above example, and its concrete structure allows to change, and those skilled in the art can make according to the present invention various changes and distortion, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
