Abstract
The utility model discloses a tension separating device comprising a first roller and a second roller which are arranged at intervals and in parallel, wherein the first roller and the second roller oppositely rotate under the drive of a driving device; a diaphragm is transmitted between the first roller and the second roller; the diaphragm moves in an S shape between the first roller and the second roller. The tension separating device has the advantages that wrinkles are not easy to generate and the diaphragm is not easy to stretch during coating.
Description
Technical field
The utility model relates to battery diaphragm process equipment, especially relates to a kind of barrier film and in the time of coating, is difficult for the tension force partition apparatus that produces fold and be stretched.
Background technology
Along with the development of coating technique, be now widely used in various technical fields, especially, in battery production, need to be coated with processing to battery diaphragm.Coating is the important operation of one in lithium ion battery separator production process, its process is exactly being coated on base material continuously even the slurry of making or interruption, barrier film coating because of base materials employed extensibility larger, therefore to carry out low-tension control, the deformation quantity that how to reduce base material on tension force cuts off or controls is a key factor that affects coated product quality.
Existing coating machine is in the time being coated with processing to battery diaphragm, to use the tension force of traditional steel rider+nip roll to cut off mode, because the thrust at two ends is inhomogeneous, while easily making barrier film coating, produce serious wrinkle phenomenon at tension force partition place, and because barrier film exists draftability, under the effect of the coating machine tension force of thrust, easily produce larger stretching, cause the outward appearance of coating machine products made thereby and mechanical property not to reach qualified requirement.
Utility model content
For addressing the above problem, the utility model object is to provide a kind of barrier film in the time of coating, to be difficult for the tension force partition apparatus that produces fold and be stretched.
The utility model is realized by following technical measures, a kind of tension force partition apparatus, comprise the first roller and second roller that spaced and parallel arranges, described the first roller and second roller opposite direction rotating under the driving of drive unit, between described the first roller and second roller, transmission has barrier film, and described barrier film becomes S shape to move between the first roller and second roller.
As a kind of optimal way, in described the first roller and second roller, one is rubber roll, and another root is steel rider.
As a kind of optimal way, one end of described the first roller and second roller is in transmission connection by two pitch wheels.
As a kind of optimal way, one in described the first roller and second roller is rotated by drive unit transmission by belt pulley.
As a kind of optimal way, described drive unit is servomotor.
As a kind of optimal way, described the first roller and second roller can be rotatably set between two fixed heads.
As a kind of optimal way, described barrier film is coated on the first roller roll surface or/and the cornerite forming on second roller roll surface is 150 °-200 °.
Compared with the tension force partition apparatus of traditional steel rider+nip roll, the utility model is because two rollers do not contact, and ensureing under the prerequisite that tension force cuts off, and barrier film is difficult for the fold producing and is stretched in the time of coating, in the time that coating completes, the outward appearance of resulting product and mechanical property are all much better than like product.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment when barrier film is not installed;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the left view of the utility model embodiment when barrier film is installed;
Fig. 4 is the side view of the utility model embodiment while using.
Detailed description of the invention
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
A kind of tension force partition apparatus of the present embodiment, please refer to accompanying drawing 1 to Fig. 3, comprise the first roller 5 and second roller 6 that spaced and parallel arranges, described the first roller 5 and second roller 6 opposite direction rotating under the driving of drive unit 1, between described the first roller 5 and second roller 6, transmission has barrier film 10, and described barrier film 10 becomes S shape to move between the first roller 5 and second roller 6.
This tension force partition apparatus is because two rollers do not contact, barrier film 10 becomes S shape to move between the first roller 5 and second roller 6, therefore ensureing under the prerequisite that tension force cuts off, the fold and the stretching that can significantly reduce barrier film coating time, easily produce, in the time that coating completes, the outward appearance of resulting product and mechanical property are all much better than like product.
The tension force partition apparatus of the present embodiment, on the basis of previous technique scheme, can also be specifically, in the first roller 5 and second roller 6, one is rubber roll, another root is steel rider.The glue plane materiel matter of rubber roll is EPDM, NBR, and the case hardness of rubber roll is Shao Shi 60-80 degree.Steel roller faces hard chrome plating, more than case hardness HRC40.
The tension force partition apparatus of the present embodiment, please refer to accompanying drawing 1 to Fig. 3, on the basis of previous technique scheme, can also be specifically, and one end of the first roller 5 and second roller 6 is in transmission connection by two pitch wheels 4,3.
The tension force partition apparatus of the present embodiment, please refer to accompanying drawing 1 to Fig. 3, on the basis of previous technique scheme, can also be specifically, and one in the first roller 5 and second roller 6 is rotated by drive unit 1 transmission by belt pulley 2.
The tension force partition apparatus of the present embodiment can also be specifically that drive unit 1 is servomotor on the basis of previous technique scheme.
The tension force partition apparatus of the present embodiment, please refer to accompanying drawing 4, on the basis of previous technique scheme, can also be specifically, and the first roller 5 and second roller 6 can be rotatably set between two fixed heads 7.
More than that the utility model tension force partition apparatus is set forth; be used for helping to understand the utility model; but embodiment of the present utility model is not restricted to the described embodiments; anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify; all should be equivalent substitute mode, be included in protection domain of the present utility model in.
