Description
Technical field
The present invention relates to a kind of roll-setting gear of extruding tablet press machine, be specifically related to a kind of roll-setting gear with two nuts.
Background technology
Extruding tablet press machine is that rubber is produced the equipment generally adopting, the goods of extruding tablet press machine have many different thickness requirements, so extrude tablet press machine when work, distance between two compressing tablet rollers often needs to adjust, as shown in Figure 1, traditional roll-setting gear of extruding tablet press machine only has a nut, nut is fixedly connected with frame, screw mandrel is driven and rotates by worm-and-wheel gear (worm gear and guide screw lock stressed joint), along the rotation of hold-down nut internal thread, move up and down and carry out roll adjustment, tradition roll-setting gear leading screw not only rotates but also move up and down, after long-term running repeatedly, leading screw head produces wearing and tearing to contact part, affect roll adjustment precision, particularly when load roll adjustment, wearing and tearing are larger, therefore traditional roll-setting gear roll adjustment that can only stop, gap after roll-setting gear turns round repeatedly between leading screw and nut can be strengthened gradually, along with the gap between nut and leading screw is strengthened gradually, when leading screw is when positive and negative both direction commutates, the screw pair of nut and leading screw also just strengthens in axial shifting amount thereupon, so just reduced roller roll adjustment accuracy, even also can cause vibrations, and gap after strengthening is difficult to recover, conventionally only have by changing the method for nut and replacing leading screw and just can reduce this gap, cost increases a lot.
Summary of the invention
The object of this invention is to provide a kind of roll adjustment precision high, adjust cost low, the double nut roll-setting gear of extruding tablet press machine of the roll adjustment of can loading.
The technical scheme that the present invention adopted is for achieving the above object: extrude tablet press machine double nut roll-setting gear, comprise leading screw (10), housing gland (11), housing (12), housing gland (11) forms enclosed cavity with housing (12), housing is equipped with worm-and-wheel gear in (12), housing (12) is fixedly connected with frame, leading screw (10) is fixedly connected with roller bearing, also comprise adjusting screw nut (7) and roll adjustment pad (8), the worm gear and nut of described worm-and-wheel gear (1) is threaded with leading screw (10), adjusting screw nut (7) is connected by the first screw (9) with worm gear and nut (1) with roll adjustment pad (8), adjusting screw nut (7) is threaded with leading screw (10), leading screw (10) is fixedly connected with frame, worm gear and nut (1) drive adjusting screw nut (7) together wrapping wire thick stick (10) rotation moves up and down leading screw (10).
Described leading screw (10) is provided with keyway.
Described adjusting screw nut (7) outside connects by first key (6) with worm gear and nut (1).
Described worm-and-wheel gear is comprised of worm screw (13) and worm gear and nut (1), and worm screw (13) is by electronic or manual drives.
Journal bearing (2) and thrust bearing (4) are installed on described worm gear and nut (1).
The upper fuel filler neck (5) of installing of described housing gland (11).
The present invention extrudes tablet press machine double nut roll-setting gear, during excesssive gap between worm gear and nut and adjusting screw nut, can reduce the thickness adjustment of roll adjustment pad, thereby reduce the shifting amount of screw thread pair, can reduce screw thread pair shifting amount, improve roll adjustment precision, adjust cost much lower compared with traditional approach, avoid leading screw to rotate the roll adjustment of can loading that weares and teares.
Accompanying drawing explanation
Fig. 1 is that tradition is extruded tablet press machine roll-setting gear schematic diagram;
Fig. 2 is the structural representation that the present invention extrudes tablet press machine double nut roll-setting gear.
Wherein: 1, worm gear and nut 2, journal bearing 3, pad 4, thrust bearing 5, fuel filler neck 6, first key 7, adjusting screw nut 8, roll adjustment pad 9, the first screw 10, leading screw 11, housing gland 12, housing 13, worm screw 14, the second screw 15, packing ring 16, the second key 17, the 3rd screw.
The specific embodiment
As shown in Figure 2, double nut roll-setting gear, mainly by housing 12, housing gland 11, worm-and-wheel gear, leading screw 10, adjusting screw nut 7 and roll adjustment pad 8 form, worm-and-wheel gear is arranged in housing 12, housing gland 11 forms enclosed cavity with housing 12, the worm gear and nut 1 of worm-and-wheel gear is threaded with leading screw 10, adjusting screw nut 7 is connected by the first screw 9 with worm gear and nut 1 with roll adjustment pad 8, adjusting screw nut 7 is threaded with leading screw 10, housing 12 is fixedly connected with frame, leading screw 10 is fixedly connected with roller bearing, leading screw 10 connects by the second key 16 with frame, the second key 16 is fixedly connected in frame by the 3rd screw 17, on leading screw 10 with keyway, the second key 16 can only slide up and down in keyway, leading screw 10 can not rotate, worm screw 13 is by electronic or manual drives, worm screw 13 drives worm gear and nut 1 to rotate, worm gear and nut 1 drive adjusting screw nut 7 together wrapping wire thick stick 10 rotations moves up and down leading screw 10, leading screw 10 can only move up and down, do not rotate, can slow down and nut between gap form, leading screw 10 heads can not rotate wearing and tearing and affect roll adjustment precision contact part simultaneously, and can realize load roll adjustment, journal bearing 2 and thrust bearing 4 are installed on worm gear and nut 1, reduce worm gear and nut 1 and rotate bias and axial float, also improved roll adjustment precision, fuel filler neck 5 is installed in order to inject lubricating oil on housing gland 11, journal bearing 2 and thrust bearing 4 and worm-and-wheel gear are lubricated, make device smooth operation, packing ring 15 is fixed on the bottom of housing 12 by the second screw 14.
Extrude tablet press machine in continuous roll adjustment process, gap between leading screw 10 and worm gear and nut 1 and adjusting screw nut 7 can be strengthened gradually, when this gap is influential to compressing tablet roller roll adjustment, can be by reducing the thickness of roll adjustment pad 8, reduce the gap between screw rod 10 and worm gear and nut 1 and adjusting screw nut 7, it is such reducing gap specific operation process: open housing gland 11, screw off the first screw 9, take out adjusting screw nut 7, take out again roll adjustment pad 8, with grinding machine, suitably grind off the thickness of roll adjustment pad 8, and then by contrary order, above-mentioned part is installed, so just can reduce gap between adjusting nut 8 and worm gear and nut 1, reduce the screw thread pair axial movement value that leading screw and nut form, can improve the precision of leading screw axial displacement.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
