The utility model has the advantages of simple structure, reliable seal, convenient operation, use, and maintenance.
Description
The utility model is a kind of gas dynamic mode roller gap adjusting mechanism that is used for feed processing machinery, belongs to the feed processing machinery technical field, is specially adapted to ring die pelleter.
At present; the adjustment in the mould roller gap of domestic granulator all is a manual adjustments; need cut off main motor power during adjusting; open door closure after the shutdown; after taking off the pressing mold cover mould roller gap is adjusted, and can not correctly be shown mould roller gap when adjusting, granulator ring mould can not make pressure roller rapidly away from the pressing mold inner surface after stopping up; thereby cause the cleaning difficulty, it is difficult to use, safeguard.
The purpose of this utility model provides a kind of gap that can regulate the mould roller before operation, in the running as required at any time; granulator ring mould can make pressure roller rapidly away from the pressing mold inner surface after stopping up; and regulate reliable; operate steadily the gas dynamic mode roller gap adjusting mechanism that mould roller gap energy digital form shows.
The technical solution of the utility model is: air motor 2 is fixed on the branch oil axle 5 by screw 1, adapter sleeve 4 one ends are fixed on the air motor 2 by screw 42, the other end is by spline and splined shaft 10 sockets, splined shaft 10 passes mainshaft gland 7, main shaft 9, gap between the two pressure roller assemblies 24 and pressing plate 16 backs socket-connect with the deceleration device of being made up of worm screw 23 and two worm gears 19 that is installed in the casing 18, two worm gears 19 are connected with two worm-wheel shafts 20 by internal gear, two worm-wheel shafts 20 are connected with an end of two adjusting rods 21 by trapezoidal thread, the other end of adjusting rod 17 is serially connected by bearing pin 33 mutually with transferring crack wheel 30, transfers the pressure roller shaft 31 in crack wheel 30 and the pressure roller assembly 24 to socket-connect by interior external gear; Divide oil axle 5 to be fixed on the mainshaft gland 7 and mainshaft gland 7 is fixed on the main shaft 9 by screw 8 by screw 6; Casing 18 is fixed on the pressing plate 16 by screw 17, pressing plate 16 is fixed on the main shaft 9 by screw 15 again, two pressure roller assemblies 24 are movably connected in respectively on main shaft 9 and the pressing plate 16 by the two ends of pressure roller shaft 31, main shaft 9 is installed in the empty axle 11 of transmission by bearing, anchor ear 13 by screw 12 empty axle 11 of transmission and ring mould 14 Joints: displacement transducer 36 by holder 35 with divide oil axle 5 affixed, its contact is near an end of adapter sleeve 4 band eccentric structures, and from the highlight distance of eccentric structure is A, the other end is connected with turn-sensitive device 39 by connecting line 37, turn-sensitive device 39 1 ends are connected on the branch oil axle 5 by screw 38, the other end is connected on the big casing by retainer ring 40, turn-sensitive device 39 links to each other with control system 26 by connecting line 25, control system 26 is linked to each other by control line 27 with baric systerm 28, baric systerm 28 links to each other with a minute oil axle 5 by tracheae 29, and dividing in the oil axle 5 has gas circuit to pass to the end away from adapter sleeve 4 of air motor 2.Adjusting rod 21 is formed by two, and two adjusting rod 21 extensions are identical, and extension is 50% of an adjusting rod trapezoidal thread length; Owing to is installed between casing 18 and the worm-wheel shaft 20 spherical bearing 34 is arranged, and worm-wheel shaft 20 is connected by trapezoidal thread with adjusting rod 21, but the compound motion of the interior swing composition of adjusting rod 21 moving linearlies and certain limit then.Shaft center line 44 offset distances of the shaft center line 43 of pressure roller 41 and pressure roller shaft 31 are B, and the rotating band dynamic pressure roller 41 of pressure roller shaft 31 is toward or away from rotatablely moving of ring mould 14; Distance between displacement transducer 36 and the adapter sleeve 4 highlights is A, and A is generally at 2～4mm.
Operation principle of the present utility model is before production or in the production process, need to regulate mould roller gap, promptly regulate between pressure roller 41 excircles and ring mould 14 inner surfaces apart from the time, but the button on the opening control 26 is also given the setting value in mould roller gap, at this moment control system 26 starts baric systerm 28 by the setting value requirement, baric systerm 28 outputs have the compressed air of certain pressure, this compressed air enters branch oil axle 5 through tracheae 29, because the pressure reduction of air drives air motor 2 and rotates, the rotating band of air motor 2 is dynamically connected and overlaps 4, splined shaft 10, worm screw 23, worm gear 19 and worm-wheel shaft 20 rotations, the rotation of worm-wheel shaft 20 drives adjusting rod 21 moving linearlies by trapezoidal thread, again owing on the worm-wheel shaft 20 spherical bearing 34 is housed, so worm-wheel shaft 20 and adjusting rod 21 can be swung within the specific limits, adjusting rod 21 is by bearing pin 33 and transfer crack wheel 30, backing pin 32 drives pressure roller shaft 31 rotations with eccentric structure, thereby pressure roller 41 is left or the approaching inner surface that encircles mould 14, when adjusting rod 21 is overhanging, pressure roller 41 cylindricals are near ring mould 14 inner surfaces, and promptly die gap reduces; Otherwise when contracting in the adjusting rod, mould roller gap increases.Control system can be sent signal and makes pressure roller rapidly away from the pressing mold inner surface when putty occurring.Because distance is A between displacement transducer 36 and the adapter sleeve 4, but because adapter sleeve has the off-centre operation structure, so when adapter sleeve rotated, actual range was at A
1～A
2Between change (see figure 4).
When mould roller gap reached the reading of setting in the control system 26, control system 26 was sent information by control line 27 to baric systerm 28, and baric systerm 28 quits work, and locatees after this original mold roller gap will reach predefined numerical value.
The available pneumatic and manual two kinds of methods of the adjustment in mould roller gap.Rotatable worm gear axle bed 22 during manual adjustments drives worm screw 23, worm gear 19 rotations, thereby realizes the purpose of adjustment.
The advantage of gas dynamic mode roller gap adjusting mechanism of the present utility model is to regulate mould roller gap as required at any time, and regulates rapidly, and is reliable and stable; And when putty, can make pressure roller 41 break away from the inner surface of ring mould 14 fast, so that clear up and maintenance; Can realize automatic and far distance controlled fully; Simple in structure, volume is little; Owing to also can adjust during work, so work front mould roller gap can be bigger, reduce the gap in the work gradually to setting value, thereby reduce the wearing and tearing of ring mould 14 and pressure roller 41, need not shut down and adjust mould roller gap.
