Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of heater.
Embodiment
Below with reference to accompanying drawing, the present invention is described in detail, as shown in Figure 1-2: the electrode slice rolling device of the present embodiment, comprise left support abutment 1 and right support abutment 2, pressure roller 3 and lower compression roller 4 is provided with between described left support abutment and right support abutment, upper pressure roller two ends are rotationally connected with left support abutment and right support abutment respectively by the first rotating shaft 5, lower compression roller two ends are also rotationally connected with left support abutment and right support abutment respectively by the second rotating shaft 6, air nozzle 7 is provided with above described upper pressure roller, also comprise air pump 8, air nozzle and air pump are all by corresponding supports support, this is prior art, described air pump is communicated with air nozzle by gas flow tube 9, described gas flow tube is provided with heater 10, in the present embodiment, described heater comprises the casing 101 be communicated with gas flow tube, electric heating tube 102 is provided with in described casing, when air-flow is by heater, can be heated.The electrode slice rolling device of this structure, lower compression roller is driven to rotate by motor, lower compression roller drives upper pressure roller to rotate, electrode slice passes from roll gap, carries out compacting, in the course of the work by upper lower compression roller to electrode slice, from air nozzle, ejection has the thermal current of certain flow rate, on the one hand, the dust accumulated on upper pressure roller and lower compression roller is blown off, avoid the consolidation effect of the interference effect electrode slice of dust; On the other hand, thermal current plays desiccation, can make the environment relatively dry of electrode slice roll-in, avoids the impact of wet environment on electrode slice consolidation effect.In sum, the electrode slice rolling device of this structure, does not have the interference of dust, and operational environment relatively dry, effectively improves the consolidation effect of electrode slice.
As the further improvement of technique scheme, described first rotating shaft left end is through left support abutment, first rotating shaft left end is arranged with driving gear 11, the driven gear 12 engaged with driving gear is provided with above driving gear, driven gear is by corresponding supports support, this is prior art, described left support abutment top is vertically provided with the first slide bar 13, the first slide block 14 is arranged with outside described first slide bar, described driven gear is connected with the first slide block by connecting rod 15, connecting rod one end and driven gear inner side end hinged near the position of profile, the other end and the first slide block hinged, the second slide bar 16 is provided with in the horizontal direction above described upper pressure roller, described second slide bar overcoat is provided with the second slide block 17, the movement of the second slide block can not interfere with air nozzle, described second slide block is connected with the first slide block by stay cord 18, back-moving spring 19 is provided with between left support abutment and the second slide block, the upper hairbrush 20 contacted with upper roller surface is provided with below second slide block.In the course of the work, first rotating shaft drives driving gear to rotate simultaneously, driving gear drives driven gear to rotate, driven gear, connecting rod and the first slide block form crank block structure, driven gear rotates and the first slide block can be driven to move up and down along the first slide bar, when the first slide block moves down, the back-moving spring being in compressive state can promote the second slide block and move from left to right along the second slide bar, thus drive above hairbrush to brush the dust on upper pressure roller from left to right, when the first slide block moves, the second slide block is driven to move from right to left by stay cord again, thus make hairbrush also movement from right to left brush the dust on upper pressure roller, so, upper hairbrush can move back and forth in left-right direction, to brush the dust that upper pressure roller gathers further, further increase the effect to electrode slice compacting.
