Abstract
The utility model discloses a double-surface seam mould extrusion coating machine of a battery pole sheet, which belongs to the range of making equipment of a battery pole sheet. The double-surface seam mould extrusion coating machine of a battery pole sheet is used for coating the active substance of a battery pole sheet of a lithium battery, particularly coating the active substance of meshy collecting liquid. A constant tension automatic coil release device and a speed adjusting constant tension coil receiving device are respectively arranged at the left side and the right side of the lower part of the double-surface seam mould extrusion coating machine of a battery pole sheet. Both heads of the battery pole sheet are respectively coiled on accurate positions on the constant tension automatic coil release device and the speed adjusting constant tension coil receiving device. A snake-shaped path which is walked by the battery pole sheet is formed from an air floating guide roller, a small guide roller, a large guide roller, a deviation correcting probe and a rotary deviation correcting device on the way, the length of equipment is effectively shortened and the space occupation of the equipment is saved. The double-surface seam mould extrusion coating machine of a battery pole sheet not only enhances coating efficiency, but also creates conditions for coating and tandem rolling. The noncontact type turn of the battery pole sheet which is well coated is carried out by the air floating guide roller, infrared heating drying step by step is realized, and the quality problem of the battery pole sheet is solved; meanwhile, the utility model can save energy 30-50 percent.
Description
Technical field
The utility model belongs to battery pole piece manufacturing equipment scope, the two-sided slit die extrusion coated of a kind of battery pole piece machine of particularly two-sided slit die extrusion coated.
Background technology
Because natural energy resources crisis and ecological deterioration, novel energy such as ni-mh, lithium ion, 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 (collector) coating equipment is more urgent.At present, import or homemade battery pole piece coating equipment all are single face or two-sided one by one horizontal transfer formula coating machine, and drying mode is 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, feels simply helpless especially for the coating of the reticulated collectors pole piece of the poly-lithium battery of fast development.
Summary of the invention
The purpose of this utility model is that the floor space at prior art the deficiency of pole piece quality problems such as bubble, pore, corn, be full of cracks greatly, often occurs and is provided for the two-sided slit die extrusion coated machine that the electrodes of lithium-ion batteries active material applies.
The technical scheme that realizes above-mentioned purpose is in the two-sided slit die extrusion coated of battery pole piece machine, the permanent tension rolling device 15 of permanent automatic unwinding device 1 of tension force and speed governing is placed on the left and right sides of coating machine bottom respectively, two of battery pole piece (collector) 21 is wound on respectively on the accurate position on unwinding device 1, the wrap-up 15, has formed the serpentine path that battery pole piece 21 is walked through air supporting deflector roll 5, little deflector roll 3, big deflector roll 10, the first correction probe 2, tension pick-up 12, rotation deviation correcting device 13 and the second correction probe 14 on the way; But temperature adjustment batch can 19 places on the helicoidal pump 17, and conduit 16 connects helicoidal pump 17 and 4, two slit die application heads 4 of two slit die application heads are separately fixed on the bent plate 20; Fixing infrared heating element 9 respectively in a drying baker 6, two drying bakers 7 and three drying bakers 8; Control cubicle 18 is arranged on the back side of the automatic unwinding device 1 of permanent tension force.
The beneficial effects of the utility model: the one, by the motion vertically upward of banded collector, especially reticulated collectors, create condition for the coating continuous-rolling of realizing coating one-shot forming of battery pole piece tow sides and battery pole piece, also improved production efficiency greatly; The 2nd, the direct extrusion coated of the slurry of active material is at the tow sides of collector, and one-shot forming, not only avoided shifting apply in battery pole piece tension force vibration unstable problem, and solved the problem that the poly-lithium battery reticulated collectors can't level applies; The 3rd, infrared heating heats the coat inside and outside simultaneously, being convenient to wet gas discharges smoothly, solved the oven dry defective of the outside in that hot-air seasoning causes, not only solved pole piece quality problems such as bubble, pore, corn, be full of cracks, and save 30～50% energy; The 4th, realized the contactless turning of the battery pole piece that do not parch fully as yet by gas suspension, dwindled device height effectively; The 5th, battery pole piece is walked serpentine curve by deflector roll in whole drying course, has shortened device length effectively, has saved widely to take up room.
