Abstract
The utility model discloses a double-surface slit mould horizontal coating machine, which belongs to a range of manufacturing equipment of battery pole sheets. A sealing coating box of the double-surface slit mould horizontal coating machine is installed on the middle position of the double-surface slit mould horizontal coating machine. Infrared generation elements, hot air suspending devices, rotary deviation rectifying guide rollers and supporting rollers are all installed in three drying boxes. The current collecting bodies of battery pole sheets pass through an automatic deviation rectifying coil release device, a constant tension transducer, the supporting rollers, the rotary deviation rectifying guide rollers, a slit mould extrusion coating head and the three drying boxes to an automatic deviation rectifying constant tension coil release device. Due to the fact that the interior and the exterior of a coating layer are simultaneously heated, moisture is favorably discharged. The double-surface slit mould horizontal coating machine not only solves the firstly exterior and secondly interior drying defect caused due to hot air drying, but also saves energy resources of 30-50 percent. The double-surface slit mould horizontal coating machine, a battery pole sheet rolling machine and a continuous strip division machine can be combined to form a battery pole sheet coating connecting and rolling system, and the length of equipment can be shortened by 50 percents. The battery pole sheets can have temperature to roll and press by coating, connecting and rolling, the deformation resistance of the battery pole sheets and thickness rebound amount after the battery pole sheets are rolled and pressed are reduced, the production efficiency of the double-surface slit mould horizontal coating machine is enhanced by two times, and the manufacturing precision of the battery pole sheets is enhanced.
Description
Technical field
The utility model belongs to battery pole piece manufacturing equipment scope, particularly is used for the horizontal coating machine of a kind of two-sided slit die of battery pole piece dual coating.
Background technology
Because fossil energy crisis and environmental pollution, novel energy such as ni-mh, lithium ion, lighium polymer, zinc air fuel cell, solar cell and energy storage mode develop rapidly.Therefore the demand of the pole piece manufacturing equipment of batteries such as ni-mh, lithium ion, the empty fuel of zinc, the empty fuel of aluminium, the empty fuel of hydrogen is also soaring day by day, and especially the demand of battery pole piece coating equipment is more urgent.At present, import or homemade battery pole piece coating equipment are that single face or two-sided one by one horizontal transfer formula apply, the hot-air seasoning method.This occupation area of equipment is big, energy consumption is high, efficient is low, pole piece quality problems such as bubble, pore, corn, be full of cracks often occur, and can not directly be connected to form automatic production line with rear portion equipment.
Summary of the invention
The purpose of this utility model provides the horizontal coating machine of a kind of two-sided slit die of the battery pole piece dual coating of batteries such as being used for lithium ion, lighium polymer.It is characterized in that: the sealing of this coating machine applies the centre position that case 1 is installed in coating machine body 22, and sealing applies permanent tension force automatic deviation correction unwinding device 2 and slit die extrusion coated 4 and 10 is installed in the case 1.First drying baker, 7 tops are provided with vent 8, inner infrared generating device 5, hot blast levitation device 6 and rotation correction deflector roll 9 and the carrying roller 11 installed.Second drying baker, 14 tops are provided with vent 8, inner infrared generating device 5, hot blast levitation device 6 and the rotation correction deflector roll 9 installed.The 3rd drying baker 20 inside are provided with vent 13, and infrared generating device 5, carrying roller 11, rotation correction deflector roll 9 and stationary barrier 17 are installed.Regulator cubicle 21 is placed on, the lower-left end of coating machine body 22.Permanent tension rolling device 24 is installed in the right-hand member of coating machine body 22, permanent tension rolling device 24 inner permanent tension pick-up 23, deflector roll 15 and the automatic deviation correction wrap-ups 16 installed.Supporting leg 18 be installed in coating machine body 22 below.
The beneficial effects of the utility model: the one, realized that by banded collector horizontal movement the battery pole piece tow sides apply one-shot forming, production efficiency improves more than 100%; The 2nd, the direct extrusion coated of the slurry of active material is at the tow sides of collector, and one-shot forming, problems such as battery pole piece tension force vibrates in the coating, the parts accumulated error is big have been avoided shifting, improved the coating uniformity of battery pole piece, meanwhile the coating thickness of all right online adjustment active material; The 3rd, infrared heating is heated the coat inside and outside simultaneously, is convenient to wet gas and discharges smoothly, has not only solved the oven dry defective of the outside in that hot-air seasoning causes, and as pole piece quality problems such as bubble, pore, corn, be full of cracks, and saves 30～50% energy; The 4th, make device length shorten 50% by battery pole piece " S " type motion, saved widely and taken up room; The 5th, can realize coating continuous-rolling, make battery pole piece band hot rolling, reduce the resistance of deformation of battery pole piece and the thickness rebound amount after the battery pole piece roll extrusion.
