Description
Technical field
The utility model relates to a kind of battery manufacturing equipment, relates in particular to a kind of power lithium-ion battery coater head bin design.
Background technology
lithium ion battery is new generation of green high-energy rechargeable battery, has that voltage is high, an outstanding advantages such as energy density is large, good cycle, self discharge are little, memory-less effect.In lithium ion battery is manufactured, closing slurry coating is one of important operation.Close the process of slurry coating by liquid medium and both positive and negative polarity active material, conductive agent, binding agent mixes, and obtains cell size, is then coated on collector, utilizes the method such as to be dried and to remove described liquid medium.Because cell size is the suspension system being mixed by different material, different materials has the different rates of settling.Even if system is uniformly dispersed, also can be because sedimentation causes slurry layering after certain hour.For the slurry of less stable, system particle is easy to reunite, and is easy to occur sedimentation in a period of time.Cause in the time of coating, slurry layering, prepared pole piece homogeneity is poor.This pole piece, for battery, can affect the performance of battery.As: the internal resistance of cell is high, capacity is on the low side, cycle performance is poor etc.The hopper part of existing coater head is the groove of a kind of wedge shape of being made up of two side shields, rear baffle and paint roller.In coating process, in order to prevent the phenomenon of electrode slurry generation sedimentation, need operating personnel ceaselessly to stir the slurry in hopper.In actual production process, this method is not only unreliable aspect the sedimentation of prevention slurry, also can cause the waste of manpower.
Utility model content
The purpose of this utility model is to provide one can prevent in coating process, the novel bin design of slurry generation sedimentation phenomenon in coater head hopper.
The purpose of this utility model can be achieved through the following technical solutions:
One power lithium-ion battery coater head hopper mechanism, comprise applicator roll, described applicator roll and right baffle plate, right baffle-plate and the backboard that is connected right baffle plate, right baffle-plate form wedge shape hopper, described wedge shape hopper bottom level is provided with feed pipe, upper level is provided with discharge nozzle, described feed pipe upper side is provided with charging hole, and the described discharge nozzle side corresponding with feed pipe is provided with discharge opening.
Described charging hole is 12 independent circular holes that two row are parallel to each other, and described discharge opening is 12 independent circular holes of a line.
Described discharge nozzle one end be provided with " S " and the discharge nozzle interface of type, the other end is blind end, described feed pipe one end is made as that " " the feed pipe interface of type, the other end is blind end to S.
The beneficial effects of the utility model: the utility model has increased discharge nozzle and feed pipe that slurry can constantly be circulated in coater head wedge shape bin design, can prevent the generation of the slurry sedimentation phenomenon in hopper in the process of coating, the utility model is simple in structure, easy to use.
