Product Description Battery Production Transfer Coater with Intermittent & Continuous Coating SystemZL-LB series coater is a professional coating equipment for lithium battery.1.It is suitable for the coating process of slurry systems such as oily or water-based lithium iron phosphate, oily lithium cobaltic acid, ternary, lithium manganate, nickel cobalt lithium manganate, oily or water-based negative carbon graphite, lithium titanate, etc;2.The tension control accuracy can reach ±1N level by using the full-automatic PID closed-loop tension control system;3.The imported standard parts such as OMRON PLC control system and high-precision servo motor are used to ensure the ultra-high consistency and stability of the coated products in terms of surface density and size. The proportion of imported standard parts is as high as 85%.SpecificationsSuitable materialsOil or water-based lithium iron phosphate, lithium cobalt, lithium manganate, ternary, lithium nickel cobalt manganate, lithium titanate, carbon graphite and other systemsOperating substrate parametersAluminum foil:Thickness: 10-30um; Width: 200-620mm; Coil diameter: max.500mm; Weight: max.500kg; Copper foil:Thickness: 6-30um; Width: 200-620mm; Coil diameter: max.500mm; Weight: max.500kg;Design width of roller650 mmEffective coating width200~580mmMechanical operation speed of equipment12m/minCoating speed0.5-8m/minSuitable material viscosity2000~12000 CpsSingle side coating dry thickness range50-150μmMinimum intermittent length5mmMinimum coating length of multi-stage20mmSolvent propertiesOily solvent: NMP(s.g=1.033,b.p=204oC)Aqueous solvent: H2O/NMP(s.g=1.000,b.p=100oC)Suitable solid contentAnode: S.C. 60%±20%Cathode:S.C. 50%±10%(PVDF system)S.C. 50%±5%(SBR system)Relative densityAnode: 1.5-2.59/cm2Cathode: 1~1.89/cm2Coating methodDouble layer double side 3-stage unequal distance intermittent transfer coating / second side automatic tracking / continuous transfer coatingRoll change modemanualBase material running directionForward coating, substrate forward and reverse empty foil operation Machine structure1. Unwinding mechanism (single arm manual rewinding)The unwinding part mainly has three functions: active unwinding, real-time automatic correction and automatic tension control;The active unwinding is powered by the motor through the synchronous pulley, and the unwinding speed is determined according to the real-time change of tension and coating speed. The whole process runs automatically to ensure the perfect matching of unwinding speed and coating speed. It avoids the large fluctuation of tension caused by the non-linear power output of the magnetic powder which can not control the unwinding speed in real time and actively when the conventional magnetic powder is passively unwinding, which affects the coating speed.Installation structure of rollerIntegral vertical plate installation (thickness 30mm)Roller surface treatmentOxidation treatment of aluminum roll surface, the surface hardness is HRC65, the run out of roll is ≤ 20 μ m, the surface roughness is Ra0.8, the parallelism is ≤ 0.1mm;Tension control systemFull automatic PID closed-loop control constant tension; unwinding tension range: 0~50N; tension control accuracy ± 1N;Correction methodAutomatic EPC control, stroke 120mmWinding methodUncoiling in up and down directionThe coil is fixed with 3-inch inflatable shaft and inflatable shaftUnwinding single inflatable shaft, double-sided supportManual splicing platform, double compression bar modeSubstrate running directionforward and backwardSubstrate running speed12m/minMaximum unwinding diameterФ500mmMaximum bearing capacity of inflatable shaft500KgNumber of unwinding inflatable shafts1Control systemSet the function operation button, which can complete the operation of tape extension, pause, emergency stop, forward and reverse, left and right alignment, etcUnwinding speedThe unwinding speed is controlled by PLC according to the set coating speed and real-time tension change data; the unwinding power is provided by AC motor + turbine reducer; 2.Coating mechanismThe head of the machine is mainly composed of scraper mechanism, steel roller mechanism, rubber roller mechanism and rubber roller drive.·The scraper mechanism drives the high-precision screw rod to drive to the inclined block through the worm reducer, and transfers to the up and down movement of the scraper through the horizontal movement of the inclined block and the inclined block, which makes the adjustment accuracy more accurate, easier to control, and greatly reduces the reverse clearance.·The steel roller mechanism is connected with the steel rod through the double diaphragm coupling through the servo motor. The steel roller bearing adopts high-precision imported bearing, which ensures the runout below 1.5um after installation through unique installation method.·Compared with the traditional rubber roller mechanism, the driving motor is fixed, and the soft connection of the double diaphragm coupling avoids the influence of the motor vibration on the coating, ensures the coating accuracy, avoids the motor and the rubber roller moving back and forth together, prolongs the service life of the motor, and reduces the inertia of the rubber roller during the coating.·The rubber roller driving mechanism connects the motor and the rubber roller through the screw rod, and converts the rotation movement of the motor into the front and back movement of the rubber roller. The rubber roller seat and the motor are installed on the movable slide block, with fast response and high precision.Installation structure50 mm thick overall vertical plate structure, 1 ton overall weightMain drive motorServo motor (750W)Intermittent push motorServo motor (750W)Roller surface treatmentThe surface of aluminum roll is oxidized, the surface hardness is HRC65, the run out of roll is ≤ 20 μ m, the surface roughness is Ra0.8, the parallelism is ≤ 0.1mm;Reducer100:1 with 750W reducerScraper structureDouble sided comma scraper, electroplated, outer diameter Φ 128mm,Blade angle rotation controlHandle rotationCoating roller (steel roller)The surface is plated with imported hard chromium, with a diameter of 128mm;TensionFull automatic PID closed-loop control constant tension, tension range 0 ~ 50N, tension control accuracy ± 1nBack roll160mm diameter, imported EPDM for surface bread, fine grinding for roll surfaceTrough mixingStraight movement of rodless cylinder, adjustable speedBaffle plateSaigang material, sealed with styrofoam, equipped with special knife mouldBlade intermittent height adjustmentServo motor adjustment: set the intermittent size of scraper and steel roller on the touch screen, with the minimum adjustment size of 0.1umStand alone head positionInstallation and operation before drying 3.Drying mechanism(infrared heating + electric heating of stainless steel heating tube) In the drying part, the fan is controlled by the frequency converter to supply air to the oven, which is heated by the electric heater before entering the oven. And equipped with hot air recycling function, effectively reducing the cost of use. Because the frequency converter is used to control the air supply motor, the air volume regulation is convenient. The fan is made of stainless steel and durable.Oven structureSingle layer independent heating, up and down arrangement, the first two heating ovens adopt the up and down independent heating bag heating mode, the second two heating ovens adopt the common heating bag heating mode.First 2 auxiliary heatingThe infrared auxiliary heating structure is adopted to prevent the cracking in the heating process and accelerate the drying speed.Oven length12m (3m / section, 4 sections in total)texture of materialStainless steel, internal container national standard SUS304 (1.0mm), external container national standard SUS201 (1.2mm)Driving mode of oven guide rollerAll guide rollers are mainly driven by servo motor with diameter of Φ 60mm and surface plated with hard chromium; the first and second guide rollers are in ascending arc distribution, the third and fourth guide rollers are in descending arc distribution with total drop of 200mm.Temperature controlIt is divided into normal working temperature control and protection control of over temperature monitoring alarm.
