On lithium battery at feed opening, for stopping freely sliding for lithium battery, it is to avoid two neighboring lithium battery is mutually close to roll down to
The conveyer belt of drying tunnel, affects the contraction quality of film；Due to there is spring bearer plate stop, cylinder is constantly from the charging of tapping channel
Propulsion lithium battery, extrudes the pressure that the lithium battery at feed opening overcomes spring bearer plate, slides to the conveyer belt of drying tunnel, keeps defeated
The lithium battery for taking is sent to be evenly distributed.
The top of spring bearer plate 47 is provided with the baffle plate 49 for placing balancing weight 48, for the position of fixed weight block.For more preferable
Balancing weight is placed on spring bearer plate, can be to arrange material retaining hood in the top of spring bearer plate, from entering in the face of balancing weight more
Row is spacing, it is to avoid the vibration of spring bearer plate, causes the displacement of balancing weight or drops.
Material retaining hood is slidably fitted on spring bearer plate, and keeps fixing by bolt and spring bearer plate.Material retaining hood edge
Spring bearer plate is slidably matched, and the position of balancing weight is adjustable, according to the lithium battery of Different Weight, can adjust the position of balancing weight, make
The gravity of the pressure and lithium battery that obtain spring bearer plate is adapted, and stops that lithium battery glides.
One end of spring bearer plate 47 is connected on the installing plate 51 above tapping channel 38, and the other end extends to tapping channel
Feed opening at and be pressed on lithium battery, formed limit lithium battery slide backgauge portion 50, lithium battery by extrude backgauge portion
Deformation, discharges tapping channel 38.
The other end of spring bearer plate 47 is to curve downward and to the arc at feed opening, with more preferable barrier effect, control
System only passes through a lithium battery every time.Backgauge portion 50 is in fork-shaped, and middle part is hollow breach, by act on lithium battery two
End, keeps the balance of lithium battery, prevents lithium battery from inclining and skids off.
The foregoing is only the preferable implementation example of the present invention, be not limited to the present invention, it is all in spirit of the invention and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
