According to the stirrer, the stability of the viscosity of the sizing agent is guaranteed, the sizing agent is conveyed to the sub-feed tube from the online stirrer through the peristaltic pump, then the sizing agent is conveyed to the coating box through the sub-feed tube, feed holes are respectively formed in two side walls of the coating box, the original manner of feeding with one tube in the middle of one side is changed into the manner of multi-path simultaneous feeding at two sides, therefore, the uniformity of the sizing agent in the coating box and the stability of the sizing agent liquid level are guaranteed, horizontal coating uniformity in the coating process is guaranteed, and the uniformity of a pole plate is further guaranteed.
Description
Technical field
The utility model relates to a kind of negative pole applying device, belongs to surperficial coating field.
Background technology
The negative material of Ni-MH battery be coated on base material-nickel plated steel strip take the MH(hydrogen storage material) be the active material of main body.The characteristics such as nickel plated steel strip smooth surface, MH proportion are bigger than normal all require the viscosity of cathode size to want high (between 100,000～180,000 cps).And the viscosity height can directly affect the mobility of slurry, and then the uniformity of impact coating.
Traditional negative pole applying device: being delivered in the slurry box by a feed pipe after the pressurization of the slurry in slurry tank, adopt the middle pipe charging of a side, flow to the both sides of slurry box under the natural gravity pressure-acting.The base material of cathode nickel plated steel strip passes slurry box (guaranteeing that by the bottom roller steel band passes bottom the slurry box) and realizes the coating engineering.In coating process, the flow complete compression weight by slurry self of slurry from the centre to both sides.Large due to viscosity, mobility is bad, when causing arriving both sides, the viscosity of slurry changes, the starching amount also changes thereupon: mid portion viscosity is low, the starching amount is little, both sides viscosity is large, the starching amount is higher.This variation has no rule and can say along with the variation of temperature, humidity, time etc., can not form rigorous quantitative management, unfavorable and quality of production management.
For above problem, a large amount of different counter-measures were done by each manufacturer, and such as reducing slurry viscosity, change coated substrate, reducing application temperature etc., all without obviously improving, perhaps, though be improved, the basic function of negative material is subject to obvious impact.
Summary of the invention
The purpose of this utility model is to provide the pasting of a kind of raising negative pole inhomogeneity negative pole applying device.
Technical solution:
The utility model comprises agitator, agitator feed pot discharging opening is provided with the feeding sebific duct, the feeding sebific duct is divided into two-way, be equipped with peristaltic pump on every road feeding sebific duct, first via feeding sebific duct is connected with sub-feed tube one port, and the second tunnel feeding sebific duct is connected with the sub-feed tube another port, is provided with at least two discharging rubber tubes on sub-feed tube, a discharging rubber tube is connected with the charging hole of pasting box one side, and another root discharging flexible pipe is connected with the charging hole of pasting box opposite side.
The magnitude setting of described discharging rubber tube is 2 multiple.
the utility model agitator is guaranteed the stability of slurry viscosity, by peristaltic pump, slurry is transported to sub-feed tube from online agitator, be transported to again in the pasting box through sub-feed tube, open respectively charging hole on the two side of slurry box, a pipe charging in the middle of an original side, due to cathode size viscosity large (between 100,000～180,000 cps), poor fluidity, by the both sides multitube charging after improving, the uniformity of the slurry in the slurry box and the stability of slurry liquid level have been guaranteed, improved the uniformity of horizontal starching in the pasting process, and then guaranteed the uniformity of pole plate, improved production efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1 online agitator; 2 paddles; 3 feed pipes; 4 peristaltic pumps; 5 pasting boxes; 6 sub-feed tubes.
The specific embodiment
Be provided with paddle 2 in the feed pot of the utility model agitator 1, the feed pot discharging opening is provided with feeding sebific duct 3, feeding sebific duct 3 is divided into two-way, be equipped with peristaltic pump 4 on every road feeding sebific duct, first via feeding sebific duct 3 is connected with sub-feed tube 6 one ports, the the second tunnel feeding sebific duct 3 is connected with sub-feed tube 6 another port, six roots of sensation discharging rubber tube is housed on sub-feed tube 6, wherein three discharging rubber tubes are connected with charging hole on pasting box 5 one sides, and another three discharging flexible pipes are connected with charging hole on pasting box 5 opposite sides.
The course of work is as follows:
Slurry applies the workshop from moving to mixing tank between batch mixing, the static placement, slurry is drawn onto in agitator 1, after making slurry viscosity keep stablizing, enter feeding sebific duct 3 from the feed pot discharging opening, slurry is transported to slurry in sub-feed tube 6 by the peristaltic pump 4 of every road feeding sebific duct 3, and isocon length conforms to substantially with base material, pasting box 5 width.Sub-feed tube 6 is evenly opened 6 discharging openings according to pasting box 5 width, and six discharging openings on isocon 6 flow out slurry to slurry box 5.At this moment slurry is because feed pressure, speed are identical, when flowing into the slurry box not only viscosity number do not change, and it is also very even to distribute, and extremely is conducive to the control of starching amount.
This slurry feed device was advanced repeatedly test, warp and former comparison of design evidence, and pasting is effective, and the pole plate uniformity is high, has improved production efficiency, and has improved greatly quality and the uniformity of battery.
