The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, the structure of the utility model automatic expansion shaft is, comprises leading screw 16, and leading screw 16 passes wallboard 7, is provided with drive part at the driving end of leading screw 16, is provided with in the operating side of leading screw 16 from the part that expands.The structure of drive part is, driving end one side of wallboard 7 is fixed with motor fixing seat 2, direct current generator 1 is installed on the motor fixing seat 2, leading screw 16 is by flexible connection 3 and 1 coaxial connection of direct current generator, be set with fixed cover 5 on the leading screw 16, be provided with deep groove ball bearing 6 between fixed cover 5 and the motor fixing seat 2, deep groove ball bearing 6 is provided with retainer nut 4 towards a side of direct current generator 1; Leading screw 16 links to each other by flexible connection 3 with direct current generator 1.
Structure from the part that expands is, the leading screw 16 of operating side one side of wallboard 7, outwards pass magnetic powder brake 8 successively from wallboard 7, connecting plate 9, sleeve 12, the hollow shaft sleeve of magnetic powder brake 8 is wherein fixedlyed connected with connecting plate 9, connecting plate 9 is connected with sleeve 12 by fifth wheel 10, the two ends of sleeve 12 are connected with leading screw 16 by radial bearing 11, on the circumference of sleeve 12 vertically symmetry have some grooves 20, the inside of sleeve 12 is provided with the screw 15 with leading screw 16 sockets, the excircle of screw 15 is scalene cone, the scalene cone of screw 15 is provided with the sliding tray 19 corresponding with each groove 20, in each sliding tray 19, be provided with a bloated sheet 14, the inner face of sheet 14 towards the axle center that expand is an inclined-plane, bloated sheet 14 outer face of circumference outward is a boss 13, the expand two ends of sheet 14 are provided with the spring mounting platform, are connected by spring 18 between the inwall of this spring mounting platform and sleeve 12.
Be used to realize that from the part that expands the swelling of paper web fixes and loosen.
Fig. 2 is from the A-A cutaway view partly that expands among Fig. 1.Sleeve 12 is fixedlyed connected with fifth wheel 10, fifth wheel 10 and connecting plate 9 are fixed together by bolt, connecting plate 9 welds together with the hollow shaft sleeve of magnetic powder brake 8 again, can rotate with axle sleeve, behind magnetic powder brake 8 logical upward exciting currents, will produce damping torque, the size of the size of the damping torque that produces and the exciting current of feeding is approximate linear, exciting current is big more, the damping torque that produces is also big more, so obtain needed damping torque (coupling mechanism force just) by the size of actual conditions adjustment feeding exciting current; On the circumference of sleeve 12 vertically symmetry have four grooves 20, put in the boss 13 of the sheet 14 that expands in each groove 20; Screw 15 and leading screw 16 sockets, the scalene cone of screw 15 are provided with the sliding tray 19 corresponding with four grooves 20, and the inner face of the sheet 14 that expands is installed in the sliding tray 19, and leading screw 16 is provided with stop collar 21, are used for mobile spacing to screw 15.
Fig. 3 is that bloated sheet in the utility model device is at the structural representation of swelling state, leading screw 16 drives screw 15 forward rotation, because the sliding tray 19 on the screw 15 is surface grooves, and the boss 13 of the sheet 14 that expands is subjected to groove 20 restrictions of sleeve 12, the sheet 14 that make to expand can not move horizontally with screw 15, so the F direction translation that screw 15 can only be in figure, the sheet 14 that expands is just outwards ejected by screw 15, boss 13 just stretches out groove 20 and exceeds the outer circumference surface of sleeve 12, thus the swelling paper web.H is the height of boss 13 among the figure, h is the wall thickness of sleeve 12, the height H of boss 13 must be greater than the wall thickness h of sleeve 12 and the spring 18 height sum after by compression, could guarantee that the outer circumference surface of boss 13 when spring 18 is subjected to expand sheet 14 compressions exceeds the outer circumference surface of sleeve 12, realizes pushing up and the swelling paper web.
Fig. 4 is that bloated sheet in the utility model device is at the structural representation of relaxation state, control leading screw 16 backward rotation, screw 15 moves the roof pressure of releasing to the sheet 14 that expands along E direction among the figure, the sheet 14 that expands shrinks to the axle center under the effect of spring 18, the outer circumference surface of boss 13 is lower than the outer circumference surface of sleeve 12, can load and unload paper web.Screw 15 is exactly that (sheet 14 drops from sliding tray 19 and screw 15 withstands on the bearing insert 17 if do not have stop collar 21 to make to expand at stop collar 21 places to the extreme position that the E direction moves, end ring is produced destruction, make bearing insert 17 and radial bearing 11 be ejected sleeve 12).
The course of work of the utility model automatic expansion shaft is:
When needs swelling paper web, earlier paper web is installed on the sleeve 12, feed exciting current for magnetic powder brake 8, magnetic powder brake 8 will produce damping torque, the sleeve 12 that restriction and fifth wheel 10 are consolidated is with leading screw 16 and screw 15 motions, and along with leading screw 16 is just changeing, screw 15 moves to right.The sheet 14 that expands is installed in the groove 20 of sleeve 12, and the sheet 14 that expands makes screw 15 not rotate, under the rotation of leading screw 16 screw 15 to the translation of F direction (as the F moving direction of Fig. 3), so the boss 13 of the sheet 14 that expands just ejected by screw 15, thereby the swelling paper web.After paper web was by swelling, screw 15 just can't continue to move to right again, made direct current generator 1 load strengthen.When damping torque that the motor-driven torque produces greater than magnetic powder brake, motor will drive paper web and rotate, thereby prevents that motor from being burnt out.Postpone the bloated sheet of regular hour assurance swelling paper web reliably by control system, control system is with magnetic powder brake 8 outages then, the damping torque of magnetic powder brake 8 disappears, the hollow shaft sleeve of magnetic powder brake 8 will rotate with sleeve 12, and the paper web that leading screw 16 just can normally drive sleeve 12 and swelling rotates puts paper or collection is operated normally.
When needs take off paper web, stop the rotation of leading screw 16 and paper web earlier, give magnetic powder brake the 8 logical exciting currents of going up, produce damping torque, restriction sleeve 12 rotates, this timed unit makes leading screw 16 backward rotation, screw 15 oppositely moves (as the E direction among Fig. 4) and unclamps the jack-up of sheet 14 of expanding, the sheet 14 that expands bounces back to the axle center under the effect of spring 18, the boss 13 of bloated sheet 14 loosens the swelling to paper web, screw 15 can only move to stop collar 21 places to the E direction, and at this moment paper web just can be removed easily.
The structure of the automatic expansion shaft of the utility model device has compared with prior art cut compressed air source unit, replaces artificial inflatable operation with electric device, makes the automatic swelling of bloated sheet in the sleeve and loosens paper roll, thereby realize that paper roll loads and unloads automation completely.
