Movement, under the action of spring three vibrating boom 83 along conveyer belt 8 sliding slot 82 move up and down, thus make top waste and old lithium
Battery vibration, loosens waste lithium cell, small size crushed material can smoothly enter into the hemispherical groove 81 of transmission, large sized object
Keep rolling for next time more efficient due to loosening.
As shown in Fig. 2, the feed opening 311 of the material storage tube 31 is located at the lower position of 8 end of conveyer belt, feed opening 311
Quantity is two, and 31 upper surface of material storage tube is in the position of feed opening 311 setting collection flitch 9, and collection flitch 9 is for making to fall on conveyer belt 8
Under metallic composite fall into material storage tube 31；The driving device 33 is worm gear, and worm gear is located at 31 top of material storage tube, worm gear
It is rotatably installed in by shaft on the front and rear wall of cabinet 1, torsional spring is provided between shaft and cabinet 1, worm gear is located at material storage tube 31
Middle position, recessing groove 313 is arranged in position of the material storage tube 31 below worm gear, and worm gear bottom passes through recessing groove 313 and is located at storage
In barrel 31, helical tooth 322 is arranged in middle position in broken shaft 32, and broken shaft 32 is meshed by helical tooth 322 with worm gear, breaks
Flight 321 on broken axis 32 is located at the left and right sides of helical tooth 322, and discharge hole 312 is located at the lower section of flight 321, discharging
312 quantity of hole is two；Winding wire ropes 10 in the shaft, 10 one end of wirerope are fixed in shaft, 10 other end of wirerope
It is connected with 24 bottom of quartering hammer.During quartering hammer 24 moves up and down, wirerope 10 is due in shaft, in torsional spring
Under the collective effect of restoring force, worm gear positive and negative rotation, rotation the nibbling by worm gear and the helical tooth 322 of broken shaft 32 of worm gear are driven
Resultant motion rotates broken shaft 32, and the rotation of broken shaft 32 drives flight 321 to carry out the metallic composite in material storage tube 31
It is repeatedly crushed back and forth, broken positive and negative pole material is fallen by discharge hole 312, and flows out cabinet 1 from discharge port 41.
Detailed process is as follows:
When work, waste lithium cell is put into cabinet 1 by feed inlet 31, then, motor rotation band moving cam 23
Movement, cam 23 periodically push pressing plate 22, and under the elastic force effect of spring one, rolling bar 21 periodically moves up and down,
The up and down motion of pressing plate 22 makes air bag 1 generate compressed air simultaneously, since helicla flute, rolling bar is arranged in 21 surface of rolling bar
21 rotate while the through-hole along cover board 3 moves downward, so that quartering hammer 24 be driven to rotate when moving downward, make
Crushing cutter 25 is rolled to waste lithium cell and circumgyration incision, improves the crushing effect of waste lithium cell, broken lithium
After battery passes through filter hole under the effect of gravity, the air that spray head 27 is blown out makes the plastics in crushed material in dropping process from modeling
13 blowout of material outlet, the plastics of blowout are fallen into collecting box 5, and metallic composite is then fallen into material storage tube 31 by feed opening 311,
Driving device 33 drives broken shaft 32 to rotate, and flight 321 crushes the metallic composite in material storage tube 31 again, just
Negative electrode material is fallen by discharge hole 312, realizes the separation of positive and negative pole material and waste residue, the positive and negative anodes for having discharge hole 312 to fall
Material, which flows out cabinet 1 through discharge port 41, realizes collection.
When rolling bar 21 drives quartering hammer 24 to move downward, rack gear 6 is located at one end and the cabinet 1 in 24 outside of quartering hammer
The contact of 11 inner wall of circular platform type groove, continues to move down, rack gear 6 is pressed into arc groove 241, and rack gear 6 is in arc with quartering hammer 24
Crushing cutter 25 is driven to rotate when movement in shape slot 241, to make crushing cutter 25 that rotation occur, crushing effect is more preferable, prismatic protrusion
On the one hand 14 presence enables waste lithium cell be pierced when gliding along 11 inner wall of circular platform type groove of cabinet 1 by prismatic protrusion 14
It is broken, broken effect is played, another aspect prismatic protrusion 14 can be such that rack gear 6 back and forth transports in the arc groove 241 of quartering hammer 24
It is dynamic, to make 25 positive and negative rotation of crushing cutter, improve broken effect.
When rack gear 6 moves back and forth in arc groove 241, the compressed air that elastic balloon 7 generates makes the piston rod of cylinder 17
The piston rod of movement, cylinder 17 pulls conveyer belt 8 along fixed block 15 to side, and the hemispherical groove 81 of conveyer belt 8 carries
Smashed waste lithium cell to 15 1 Slideslip of fixed block, and can smoothly enter into the rectangular recess 12 of cabinet 1, cylinder 17
It shakes conveyer belt 8 while pulling conveyer belt 8, crushed material in hemispherical groove 81 is shaken off out of hemispherical groove 81, bullet
The presence of spring two moves conveyer belt 8 under the action of elastic force to two side of spring, so that conveyer belt 8 carries crushed material by solid
Determine 15 other side of block to enter in the rectangular recess 12 of cabinet 1.Side-to-side movement under the action of cylinder 17 and spring two of conveyer belt 8
When, the vibrating boom 83 in 1 circular platform type groove 11 of cabinet is contacted with smashed lithium battery, with the movement of conveyer belt 8,
Vibrating boom 83 moves up and down along the sliding slot 82 of conveyer belt 8 under the action of spring three, thus make the waste lithium cell vibration of top,
Loosen waste lithium cell, small size crushed material can smoothly enter into the hemispherical groove 81 of transmission, and large sized object is due to loosening
Keep rolling for next time more efficient.
During quartering hammer 24 moves up and down, wirerope 10 is due in shaft, in being total to for torsional spring restoring force
Under same-action, worm gear positive and negative rotation is driven, the rotation of worm gear is made brokenly by the gear motion of worm gear and the helical tooth 322 of broken shaft 32
Broken axis 32 rotates, and the rotation of broken shaft 32 drives flight 321 to carry out repeatedly back and forth the metallic composite in material storage tube 31
Broken, broken positive and negative pole material is fallen by discharge hole 312, and flows out cabinet 1 from discharge port 41.
More than, it is illustrated about one embodiment of the present invention, but the present invention is not limited to the above embodiments,
It does not depart from and is able to carry out various changes in the range of present subject matter.
