Description

In, low rigid Bulky Waste disintegrating machine

Technical field

The utility model relates to a kind of Bulky Waste disintegrating machine, particularly in ready-made clothes, rag class, footwear, leatherware case and bag class, plastic products class, the bamboo wood furniture class etc., low rigid Bulky Waste disintegrating machine.

Background technology

At present, enhancing gradually along with people's environmental consciousness, domestic waste develops to nuisanceless resource direction, waste incineration and generating electricity is comparatively ideal waste disposal method, the sorting of rubbish is pretreated important step, for the high heating value that sub-elects, in, low rigid Bulky Waste, as ready-made clothes, the rag class, footwear, leatherware case and bag class, the plastic products class, bamboo wood furniture class etc., now extensively adopt pair roller type to disassemble disintegrating machine and scissor shredding machine carries out granulation, the former, as depicted in figs. 1 and 2, comprise charging aperture 20, frame 21, discharging opening 22, bearing 32 by two ends is installed in the double-roller type broken shaft 23 on the frame 21, drive double-roller type broken shaft 23 and make the Power Drive Unit of relative differential rotation, wherein every roll crushing axle 23 comprises main shaft 24, be installed on the main shaft 24 by flat key, several axle sleeves 25 that have the sword tooth, all axle sleeves 25 are fixing by step on the main shaft 24 and locking nut 26; Power Drive Unit is made up of motor 27, belt gear 28, reductor 29, shaft coupling 30, a pair of gear 31 that is installed on two main shafts 24, and this Power Drive Unit also can be formed (not shown) by the belt gear and the motor that connect with two main shafts respectively; Double-roller type broken shaft 23 is driven by Power Drive Unit and does relative differential rotation, rubbish in the middle of the double-roller type broken shaft by the time discharged from both gaps by the chopping of the sword tooth on the axle sleeve 25 back, this disintegrating machine has following shortcoming: (1) is when Bulky Waste falls into from charging aperture when carrying out fragmentation between the double-roller type broken shaft 23, because Bulky Waste has out-of-shape, the accumulation voidage is big, the characteristics of mobile difference, wherein the less rubbish of proportion difficult between the double-roller type broken shaft 23 by carrying out fragmentation, cause part rubbish to be deposited in the top of two pair roller type broken shafts 23 for a long time, can not normally walk material, feeding speed is uncontrollable, has reduced crushing efficiency; (2) owing to there is big space between the double-roller type broken shaft 23, the possibility of leaking material is arranged, cause broken back granularity inequality; (3) the flexible rubbish that proportion is less, area is bigger in the middle of double-roller type broken shaft 23 by the time the suffered power of pullling deficiency, blanking velocity is slower, has further reduced crushing efficiency.

The utility model content

The purpose of this utility model is the above-mentioned shortcoming at prior art, provide a kind of can control feeding speed and guarantee broken back even-grained in, low rigid Bulky Waste disintegrating machine, it has the high advantage of crushing efficiency.

For achieving the above object, in of the present utility model, low rigid Bulky Waste disintegrating machine, comprise charging aperture, frame, discharging opening, double-roller type broken shaft, drive the Power Drive Unit that the double-roller type broken shaft is done relative differential rotation, it is characterized in that also being provided with the forced feeding device between charging aperture and double-roller type broken shaft, this forced feeding device comprises that being installed in twice material rollers, twice material rollers of driving of also being installed with one group of blade on the frame respectively makes counterrotating Power Drive Unit;

Twice material rollers of above-mentioned driving are made counterrotating Power Drive Unit and are comprised and the engagement gear ring on the reductor that connects of material roller and motor, a pair of axle journal that is separately positioned on outer twice material rollers of frame once wherein; Drive twice material rollers by motor, reductor and a pair of gear ring and do relative rotation with two groups of blades, rubbish by charging aperture by after between twice material rollers, part proportion the greater, thereby directly contact with the double-roller type broken shaft by discharge after the chopping, part proportion smaller is stacked into to a certain degree and contacts with the blade on top, under the extruding of blade, be compressed, evenly quicken to pass through between the double-roller type broken shaft downwards, thereby realization has improved crushing efficiency to the control of charging rate;

As further improvement of the utility model, described every roll crushing axle comprises two main shafts that several axle sleeves and dise knife are installed at interval, each axle sleeve outer is provided with tooth, each dise knife on two main shafts embeds in the teeth groove of corresponding axle sleeve on the other side's main shaft respectively, can obviously reduce the space between the double-roller type broken shaft, anti-leak-stopping material guarantees to pulverize the back epigranular; The flexible rubbish that simultaneously part proportion is less, area is bigger is down pullled by brute force with after the crown on the axle sleeve contacts, and blanking velocity is fast, has further improved crushing efficiency.

In sum, the utility model can be controlled feeding speed and guarantee broken back epigranular, has the high advantage of crushing efficiency.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

By Fig. 3, Fig. 4 and shown in Figure 5, should in, low rigid Bulky Waste disintegrating machine, comprise that charging aperture 1, frame 2, discharging opening 3, the bearing 17 by two ends are installed in double-roller type broken shaft 4 on the frame 2, drive double-roller type broken shaft 4 and make the Power Drive Unit of relative differential rotation, be arranged on the forced feeding device between charging aperture 1 and the double-roller type broken shaft 4; Every roll crushing axle 4 comprises several axle sleeves 11 and the dise knife 12 that is installed in main shaft 13 by flat key at interval, and axle sleeve 11 and dise knife 12 are fixed on the main shaft 13 by step on the main shaft 13 and locking nut 16, each axle sleeve 11 outer is provided with tooth, on two main shafts 13 each coiled in the teeth groove that 12 cuttves embed corresponding axle sleeve 11 on the other side's main shaft 13 respectively, can obviously reduce the space between the double-roller type broken shaft 4, guarantee to pulverize the back epigranular; This Power Drive Unit is by forming with the belt gear 14 and the motor 15 of the connection of two main shafts respectively; This forced feeding device comprises that the bearing 5 by two ends is installed in twice material rollers 6 on the frame 2, twice material roller all is installed with one group of blade 7, wherein once material roller is driven by motor 8 and reductor 9, and pair of meshing gear ring 10 is separately positioned on the axle journal of outer twice material rollers 6 of frame;

The course of work of the present utility model is: rubbish is entered in the frame 2 by charging aperture 1, under stirring of blade 7 squeezed, be compressed and evenly quicken, pass through downwards, discharge by gap between the two thereby part proportion the greater directly contacts by the chopping back with the dise knife 12 of two groups of differential rotations; Part proportion smaller is stacked into the extruding that to a certain degree is subjected to upper blade 7, is pushed away down by force, after the crown of band tooth axle sleeve 11 contacts, is down pullled by brute force, is discharged by the dise knife 12 chopping backs that differential rotates; Because the dise knife 12 of two groups of differential rotations embeds respectively in the teeth groove of the other side's axle sleeve 11, do not leak the material possibility so do not exist, grinding particle size is even.
