Detailed description of the invention
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
External pressure roller 42 formula granulator, comprises pedestal 1, hopper 5, ring mould 2, pressure roller 42 and motor 3, it is characterized in that: pressure roller 42 is arranged on outside ring mould 2, and hopper 5 is arranged on above the gap between pressure roller 42 and ring mould 2.The present invention breaks traditions the extruder grain mode of ring mould 2 granulator, pressure roller 42 is arranged on outside ring mould 2, by ring mould 2 exocyclic mould 2 inner chamber extruder grain, such design makes ring mould 2 greatly increase with the storing space of pressure roller 42 contact site, namely increase the space of moment constricted zone, make the working ability of granulator obtain rapid growth, due to the working environment high temperature in forming cavity in conventional particles machine, high humidity, high dust, the interior pressure roller shaft 41 arranged of pressure roller 42 be arranged in ring mould 2 inner chamber is held to be needed to safeguard frequently, and immediately carry out thoughtful and comprehensively safeguard, pressure roller shaft 41 is held and is also very easily damaged, by above-mentioned design, pressure roller 42 is arranged on outside ring mould 2, the working environment that pressure roller shaft 41 is held obtains and improves greatly, reduce the frequency of maintenance that pressure roller shaft 41 is held, this not only reduces the replacement cost of consumable accessory, also reduce equipment failure rate simultaneously, the normal production time of support equipment, improve working (machining) efficiency, reduce production cost, in addition, there is ring mould 2 exocyclic mould 2 inner chamber extruder grain, using ring mould 2 inner chamber as the collection space of particle and terminal, do not need the structure of additional designs collecting granules, make the structure of granulator more simple, be convenient to safeguard, during conventional particles agent running, pressure roller 42 not only wants pressing materials to do work, also has a big chunk energy for overcoming the resistance of material in forming cavity simultaneously, make pressure roller 42 and ring mould 2 smooth rotation, by design of the present invention, the merit of the overwhelming majority is used for extruder grain by granulator, wastes energy in other respects hardly, substantially increases the utilization ratio of energy.
Hopper 5 is made up of two blocks of side plates 51 and two end plates 52, and the outline of the bottom shape of side plate 51 and ring mould 2 and pressure roller 42 contact site matches, and two end plates 52 is respectively near the lateral surface of pressure roller 42 and ring mould 2.Because the rotation direction of ring mould 2 and pressure roller 42 is contrary; be all from top to bottom, ecto-entad rotates towards gap; at hopper 5 and ring mould 2 with do not need between hopper 5 and pressure roller 42 to design extra leakage preventing mechanism; the side plate 51 bottom design Cheng Yuhuan mould 2 of hopper 5 and the outline of pressure roller 42 is only needed to match; when granulator works; along with the rotation of pressure roller 42 and ring mould 2; negative pressure can be formed at end plate 52 and pressure roller 42 and end plate 52 with the contact site of ring mould 2, make material can not spill hopper 5.
The width of hopper 5 bottom discharge mouth is not more than the width of the narrower person of width in ring mould 2 and pressure roller 42.Due to hopper 5 and special design, in fact hopper 5 also has accurately to the effect of effective constricted zone feeding, also narrower than the width of the narrower person of width in ring mould 2 and pressure roller 42 by the bottom opening width design of hopper 5, anti-leak-stopping material on the one hand, conveniently control rate of feeding on the other hand, prevent the too fast overload that causes of feeding from getting stuck.
Ring mould 2 is arranged on die holder 21, die holder 21 is connected with the axle center of gear wheel 8 by the power transmission shaft 81 running through mould bases plate 22, mould bases plate 22 is run through in power transmission shaft 81 one end, its other end is rotating to be fixed on gear frame plate 32, gear wheel 8 is engaged by the power gear 31 be connected with motor 3 and obtains kinetic energy, and mould bases plate 22 and gear frame plate 32 are set in parallel on pedestal 1.By the design of mould bases plate 22 and gear frame plate 32, ring mould 2 and transmission mechanism are securely fixed on pedestal 1, action is transmitted directly, and structure is simple, is convenient to safeguard.
Pressure roller 42 is fixed between two regulating arms be arranged in parallel 7 by pressure roller shaft 41, be fixed on pedestal 1 by Connection Block 72 is rotating bottom regulating arm 7, regulating arm 7 top is connected with telescoping mechanism 6, and regulating arm 7 stage casing is provided with axis hole 71, and pressure roller shaft 41 is arranged in axis hole 71.By the design of regulating arm 7 and telescoping mechanism 6, utilize lever principle cleverly, strengthen the strength of adjustment for pressure roller 42 and degree of regulation; Due to pressure roller 42 along with use can be worn and torn, often need in production process often to shut down adjusting play, thus ensure the stable of production process, but this can cause a large amount of wastes of time undoubtedly, manual adjustment also needs to drop into a large amount of manual labor frequently simultaneously, " online " adjustment pressure roller 42 gap can be realized by such design, namely need not shut down and adjust pressure roller 42 gap as required at any time in process of production, also a saving manpower while enhancing productivity, production cost is reduced; In addition; by the programming Control to telescoping mechanism 6; can realize automatic in the case of an overload the gap between pressure roller 42 and ring mould 2 being tuned up; reach the effect reducing load, prevent stuck situation, after load is reduced to predetermined value; gap is adjusted to normal value by telescoping mechanism 6 again; by such adjustment, can not only effectively prevent to get stuck the situation causing motor 3 to burn out, and the equipment that also achieved completes the process of overload unloading under non-stop-machine situation.
Gear frame plate 32 and mould bases plate 22 top are provided with built-in beam 61, and built-in beam 61 stretches out to ring mould 2 side, and the base of telescoping mechanism 6 is fixedly installed on built-in beam 61.By built-in beam 61 being designed the scheme at gear frame plate 32 and mould bases plate 22 top; reduce the number of components that pedestal 1 is arranged, simplify the structure of granulator entirety, make granulator overall structure simple; be convenient to safeguard, reduce assembling complexity and production cost simultaneously.
Telescoping mechanism 6 selects hydraulic jack.Oil cylinder structure of hydraulic is simple, reliable operation, and when realizing moving back and forth with it, can remove deceleration device from, and not have drive gap, stable movement, its action control is accurate simultaneously, High power output and steadily, can ensure carrying out smoothly of extruder grain process.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
