Abstract
The invention discloses a secondary crushing device for recycling waste electric wires and cables. The secondary crushing device comprises a box body, wherein a main shaft is supported on the box body; the main shaft is driven by a motor; and the box body is provided with a fixed blade. The secondary crushing device is characterized in that: the main shaft is provided with an eccentric shaft sleeve; and the eccentric shaft sleeve is provided with a movable blade. Compared with the prior art, the secondary crushing device realizes changes of a gap between the fixed blade and the movable blade in the operation process by connecting the eccentric shaft sleeve with the movable blade, so that the aim of simultaneously crushing and effectively recycling the waste electric wires and cables with different diameters is fulfilled.
Description
Technical field
The present invention relates to a kind of retracting device of scrap electrical wires cable, particularly a kind of second-time breakage device that is used for the recovery of scrap electrical wires cable.
Background technology
Copper is the indispensable raw material of modern industry, also is the important strategic goods and materials.Because a large amount of productions of the former pig copper have made limited copper ore resource constantly reduce, the production of the former pig copper simultaneously can produce a large amount of industrial residues, waste liquid, waste gas etc., and seriously contaminated environment is destroyed the ecological balance.Therefore, the recycling of useless composition brass is all paid much attention in countries in the world, and reclaimed copper has become the important source that remedies the copper inadequate resource.
Be accompanied by the development of modern industry and communications industry, the demand of various plain conductors is also increasing, because the cycle of model change shortens, the scrap electrical wires number of cables that needs in the society to reclaim also constantly increases simultaneously.Also relatively shortage of the copper resource of China simultaneously, the therefore recovery of waste and old cable has very important significance for the utilization of copper resource.When reclaiming copper, also can carry out recycling to rubber, the parts of plastics of waste and old cable, therefore the recovery to waste and old cable meets the theory of building a conservation-minded society.
Waste cable retracting device (being commonly called as copper rice machine) is the capital equipment that present waste cable is disassembled.The copper rice machine of various patterns and structure is arranged at present on the market, but generally speaking all forms by five big systems:
(1) primary fragmentation system (also claiming the coarse crushing system): its effect is that breaking up waste cable is become short line segment.Present primary fragmentation system adopts rotation broken mostly.
(2) belt conveyor system: its effect is that the raw material with primary fragmentation is transported to the second-time breakage system, simultaneously in belt system, is typically equipped with the device of body magnetisable material such as iron particle in the absorption raw material.
(3) second-time breakage system (also claiming the fine crushing system): this system is the key of copper rice crusher machine, and its effect is to grain of rice size with the raw material cutting and crushing after the coarse crushing.This system mainly is made up of stationary knife and moving knife.During work, the moving knife rotation, stationary knife is fixed on the cavity, obtains crushing effect preferably by the gap between prior adjustment moving knife and the stationary knife.
(4) screening system: its effect is that copper is separated with wire outer skin.Common separation method has two kinds: the one, and vibration+wind filter method; The 2nd, the washing partition method.
(5) control system: adopt the PLC computer control system, control and coordinate the running of each system.
The subject matter of existing copper rice machine is can only carry out fragmentation to the copper wire of single diameter in the second-time breakage system.Because seek out good crushing effect, need be in the gap between second-time breakage stage adjustment moving knife and the stationary knife, make gap between them be slightly smaller than the diameter of electric wire and greater than the diameter of copper wire, thereby clearance issues is exactly one of key issue of limit copper rice crusher machine different-diameter copper wire.Yet the gap of moving knife and stationary knife is nonadjustable in running in the present copper rice machine second-time breakage device, therefore can only carry out fragmentation to the copper wire of single diameter.When the different-diameter copper wire is sent into the second-time breakage device simultaneously, can't obtain good crushing effect.
Summary of the invention
The present invention is for solving the second-time breakage device that the scrap electrical wires cable reclaims that is used for that the technical problem that exists in the known technology provides a kind of broken different-diameter cable simultaneously and can obtain good crushing effect.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of second-time breakage device that is used for the recovery of scrap electrical wires cable, comprise casing, described casing upper support has main shaft, described main shaft is by motor-driven, on the described casing stationary knife is installed, on the described main shaft excentric sleeve is installed, on the described excentric sleeve moving knife is installed.
Described excentric sleeve is connected by key respectively with described main shaft with described moving knife.
Advantage and good effect that the present invention has are: compared with prior art, by adopting the structure that on excentric sleeve, connects moving knife, realized the variation of stationary knife and moving knife gap in running, and then realized the waste cable with different-diameter is carried out the broken simultaneously purpose that effectively reclaims.

Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1～Fig. 5, a kind of second-time breakage device that is used for the recovery of scrap electrical wires cable, motor 1 drive main shaft 2 motions, and main shaft 2 drives moving knife 5 by excentric sleeve 6 and moves.Gap between moving knife 5 and the stationary knife 4 changes along with the variation of time, thereby has realized cutting simultaneously the purpose of different-diameter cable.
Above-mentioned main shaft 2 is bearing on the casing 3 by bearing.Above-mentioned excentric sleeve 6 is connected by key respectively with described main shaft 2 with described moving knife 5.Therefore should have two keyways at least on the excentric sleeve 6, be respectively applied for connection main shaft and moving knife.
Have certain clearance between above-mentioned moving knife and the stationary knife, the specification of excentric sleeve is depended in the variation in gap, and the maximum difference in gap should be 2e=D-d, and wherein, D represents the maximum ga(u)ge of excentric sleeve; D represents the minimum thickness of excentric sleeve; E represents the eccentric throw of excentric sleeve, and determining of eccentric throw is relevant with the difference that is cut cable diameter, should be and is cut 1/2nd of cable diameter maximum difference.
See also Fig. 5, figure mid point O represents the center of circle of main shaft 2, and the axis at O place is the axis of casing 3; Point O
1The center of circle of expression excentric sleeve 6 cylindricals, excentric sleeve 6 is different with the axis of casing 3.When excentric sleeve 6 under the drive of main shaft 2, during with main shaft 2 rotation, connect moving knife 5 thereon and the gap that is fixed between the stationary knife 4 on the casing 3 constantly changes, be implemented in finally that the gap changes this purpose between stationary knife 4 in the shattering process and the moving knife 5.
Although in conjunction with the accompanying drawings the preferred embodiments of the present invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
