One, and the downside of connecting rod is connected with the piston rod no. Two, and no. One the piston rod is connected with a cylinder, and no. Two the piston rod is connected with no. Two cylinders. The utility model discloses a can carry out the floating roll that fluctuates, the tension change of the lithium ion battery diaphragm that regulation that can be nimble arouses because of speed changes makes the quality of lithium ion battery diaphragm more stable.
Description
Technical field
This utility model relates to battery technology apparatus field, specifically a kind of lithium ion battery separator float roller device.
Background technology
Lithium ion battery is a kind of secondary cell (rechargeable battery), and it relies primarily on lithium ion and moves work between a positive electrode and a negative electrode.In charge and discharge process, lithium ion comes and goes between two electrodes and embeds and deintercalation；During charging, lithium ion, from positive pole deintercalation, embeds negative pole through electrolyte, and negative pole is in rich lithium state；During electric discharge then contrary.Battery is generally adopted the material containing elemental lithium as electrode, is the representative of modern high performance battery.
In the structure of lithium ion battery, barrier film is one of crucial interior layer assembly.For lithium battery series, owing to electrolyte is organic solvent system, so that there is the diaphragm material of organic solvent-resistant, it is generally adopted the polyolefin porous membrane of high-strength thin-film.
In the transmission stage of lithium ion battery separator in prior art, it does not have the structure of design dancer, when transmission speed is too fast, the tension force on barrier film can increase, thus affecting barrier film quality.
Utility model content
The purpose of this utility model is in that to provide a kind of lithium ion battery separator float roller device, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of lithium ion battery separator float roller device, including two live-rollers, it is connected with dancer between two live-rollers, one end of connecting plate is located at by dancer, and the other end of connecting plate is connected on fixing bearing, in the centre position of connecting plate, is perpendicular to connecting plate and is provided with connecting rod, the upside of connecting rod is connected to a piston rod, the downside of connecting rod is connected to No. two piston rods, and a piston rod and a cylinder connect, and No. two piston rods and No. two cylinders connect.
As further program of the utility model: described fixing bearing and connecting rod are connected each through bolt and connecting plate are fixing.
Compared with prior art, this utility model is by carrying out the dancer fluctuated, it is possible to regulating the tension variation of the lithium ion battery separator caused because of rapid change flexibly, the quality making lithium ion battery separator is more stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of lithium ion battery separator float roller device.
In figure: 1-live-roller, number cylinder of 2-, 3-connecting plate, 4-fix bearing, 5-bolt, 6-connecting rod, No. bis-cylinders of 7-, 8-dancer, number piston rod of 9-, No. bis-piston rods of 10-.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of lithium ion battery separator float roller device, including two live-rollers 1, it is connected with dancer 8 between two live-rollers 1, one end of connecting plate 3 is located at by dancer 8, the other end of connecting plate 3 is connected on fixing bearing 4, centre position at connecting plate 3, it is perpendicular to connecting plate 3 and is provided with connecting rod 6, the upside of connecting rod 6 is connected to a piston rod 9, the downside of connecting rod 6 is connected to No. two piston rods 10, a number piston rod 9 is connected with a cylinder 2, No. two piston rods 10 are connected with No. two cylinders 7, described fixing bearing 4 and connecting rod 6 are connected each through bolt 5 is fixing with connecting plate 3.
When being operated, when transmission speed is too fast, the tension force on lithium ion battery separator surface increases, a number cylinder 2 is compressed, the piston rod 9 being connected with a cylinder 2 drives connecting rod 6, it is applied on connecting plate 3, make dancer 8 moves, reduce the distance between dancer 8 and live-roller 1, so that lithium ion battery separator surface tension reduces, and when speed is by when returning to normal soon, No. two cylinders 7 that bottom is stretched bounce back, No. two piston rods 10 being connected with No. two cylinders 7 drive connecting plate 3, dancer 8 is made to move down, lithium ion battery separator is made to recover normal transmission distance.
This utility model is by carrying out the dancer fluctuated, it is possible to regulating the tension variation of the lithium ion battery separator caused because of rapid change flexibly, the quality making lithium ion battery separator is more stable.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in this utility model.Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but not each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should be made as a whole by those skilled in the art, and the technical scheme in each embodiment through appropriately combined, can also form other embodiments that it will be appreciated by those skilled in the art that.
